Description

BACKGROUND OF THE PRESENT INVENTION

[0001] 1. Field of Invention

[0002] The present invention relates to a hair removal device, and more particular to an epilation method and apparatus thereof which is an electrical powered device for effectively plucking the hair at the follicle level by means of threading technique.

[0003] 2. Description of Related Arts

[0004] Threading is an ancient method of hair removal, wherein it is extremely effective and is becoming very popular in the West. Accordingly, threading technique involves a cotton thread being held the practitioner's hands to roll over untidy hairlines, moustaches and other areas of unwanted hair, so as to pluck the hair in a twisting motion. However, threading can be hard for an inexperienced person to practice that the cotton thread will break the hair instead of pluck the hair. In fact, it can be hard to find someone who experiences threading hair and can be hard for someone to learn threading.

[0005] An epilator is provided as a thread holder to hold the thread in position for threading. The epilator generally comprises two moving arms as the practitioner's hands to hold the thread in a twisted manner. The user is able to move the moving arms to simulate the threading motion to remove the hair. However, the moving arms require relatively large space to move reciprocatingly. In other words, the epilator cannot apply to small area such as moustaches to remove the hairs thereat. In addition, the epilator can only be operated manually, i.e. by the user hands to move the moving arms. The epilator cannot be incorporated with any powering device, such as a motor, because the powering device must generate a corresponding motion for each moving arm while such motions of the moving arms must be synchronized to simulate the threading motion.

[0008] Another advantage of the invention is to provide an epilation apparatus, wherein the thread is driven to twist by the rotatable arm to simulate a threading motion. In other words, the thread will only be twisted to generate the threading motion without substantially pulling or stretching the thread during operation.

[0009] Another advantage of the invention is to provide an epilation apparatus, wherein the thread is coupled with the rotatable arm through a resilient element such that the resilient force is applied to the thread during twisting to self-adjusting the tension of the thread so as to prevent the thread being broken.

[0010] Another advantage of the invention is to provide an epilation method, which is simple and easy to operate, wherein an inexperienced person is able to operate the epilation apparatus to provide a professional threading technique.

[0011] Another advantage of the invention is to provide an epilation method, wherein the user is able to easily couple the thread to the epilation apparatus by only coupling three points of the thread to the epilation apparatus.

[0012] Another advantage of the invention is to provide an epilation apparatus, which is extremely sanitary that only the thread will touch the skin of the user and the thread will be thrown away after use.

[0013] Another advantage of the invention is to provide an epilation apparatus, which can hold any existing thread to complete the threading operation, so as to minimize the additional cost of the thread incorporating with the epilation apparatus.

[0014] Another advantage of the invention is to provide an epilation apparatus, wherein no expensive or complicated structure is required to employ in the present invention in order to achieve the above mentioned objects. Therefore, the present invention successfully provides an economic and efficient solution for providing a device for effectively generating a threading motion to twist the thread for removing finest and smallest hair, such as facial hair, with ease without leaving the area extremely swollen or red like waxing does.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0031] Referring to FIGS. 1 to 3 of the drawings, an epilation apparatus according to a preferred embodiment of the present invention is illustrated, wherein the epilation apparatus is arranged for holding a thread 10 in position to complete the threading operation. The epilation apparatus comprises a body 20 and a thread operating device 30.

[0032] The body 20 comprises a housing 21 defining a front side 211, and two spaced apart holding arms 22 frontwardly extended from the front side 211 of the housing 21. The housing 21 has a receiving cavity therein to receive the thread operating device 30. In particular, the two holding arms 22 are integrally extended from the housing 21 to define two free ends of the holding arms 22. Accordingly, the two holding arms 22 are immovable with respect to the housing 21 that a distance between the free ends of the holding arms 22 are fixed.

[0033] The thread operating device 30 comprises a powering unit 31 supported within the housing 21 of the body 20 and a rotatable arm 32 extended from the body 20 between the holding arms 22. In particular, the rotatable arm 32 is extended from the front side 211 of the housing 21 at a position between the holding arms 22.

[0034] As shown in FIGS. 1 to 3, the thread 10, such as a cotton thread, is held by the epilation apparatus by a three-point support. Two free ends of the thread 10 are detachably coupled at the free ends of the holding arms 22 respectively. A mid-portion of the thread 10 is detachably coupled at the free end of the rotatable arm 32. In other words, the thread 10 is held in a V-shaped configuration. When the rotatable arm 32 is driven to reciprocatingly rotate by the powering unit 31, the mid-portion of the thread 10 is twisted to simulate a threading motion. Therefore, by placing the thread 10 on the skin of the user, the threading motion of the thread 10 will trap hairs in the twisted thread 10 and will pull the hairs out.

[0035] It is worth mentioning that the two holding arms 22 are immovable such that only the mid-portion of the thread 10 is twisted by the rotatable arm 32 so as to provide a stable threading operation. In addition, the twisting motion of the thread 10 will minimize the tension of the thread 10 to prevent the thread 10 from being broken.

[0036] As shown in FIGS. 1 and 4, the body 20 further comprises a through slot 23 provided at the front side 211 of the housing 21 at a position between the holding arms 21, wherein the through slot 23 is arranged to communicate with the receiving cavity of the housing 21. In particular, the rotatable arm 32 is aligned with the through slot 23 such that the mid-portion of the thread 10 can couple at the free end of the rotatable arm 23 through the through slot 23. The rotatable arm 32 is also adapted to be pulled out of the front side 211 of the body 20 through the through slot 23 thereof when the thread is twisted.

[0037] The front side 211 of the housing 21 is configured as a concave surface, wherein the through slot 23 is formed at a vertex of the concave front side 211 of the housing 21, so as to maximize the distance between the free end of the rotatable arm 32 and the free end of each of the holding arms 22. In other words, the length of the thread 10 will be prolonged to enhance the threading operation.

[0038] As shown in FIGS. 2, 3 and 5, the powering unit 31 comprises a power source 311 and a motorized unit 312 operatively linked to the power source 311 for generating a reciprocatingly rotational power to the rotatable arm 32.

[0039] The power source 311, which is supported within the housing 21, comprises a rechargeable battery and a charging outlet provided at a rear side of the housing 21. It should be appreciated that the power source 311 can be embodied as a battery compartment for receiving a battery thereat to operatively link to the motorized unit 312, wherein the battery can be a disposable battery or a rechargeable battery.

[0040] The motorized unit 312 comprises an electric motor supported within the housing 21 and an output shaft extended from the electric motor for generating a reciprocatingly rotational power. Accordingly, the reciprocatingly rotational power is transmitted to the rotatable arm 32 in order to drive the rotatable arm 32 to rotate.

[0041] The powering unit 31 further comprises an operation switch 313 provided at the top side of the housing 21 and a circuit board 314 supported within the housing 21, wherein the operation switch 313 is arranged to activate the motorized unit 312 through the circuit board 314 in order to drive the rotatable arm 32 to rotate. In particular, when a depression force is applied to the operation switch 313, the motorized unit 312 will be activated. When the depression force is then applied to the operation switch 313, the motorized unit 312 will be deactivated.

[0042] As shown in FIGS. 2 and 3, the rotatable arm 32 comprises a resilient arm 321 extended at the first side 211 of the body 20 for coupling with the mid-portion of the thread 10, wherein the resilient arm 321 is arranged for applying a resilient force to the thread 10 to self-adjusting a tension of the thread 10 when the thread 10 is driven to twist. According to the preferred embodiment, the resilient arm 321 is a compression spring having a front end as the free end of the rotatable arm 32 to couple with the mid-portion of the thread 10.

[0043] Accordingly, when the mid-portion of the thread 10 is twisted, the thread 10 will be pulled against the free ends thereof. When a substantial pulling force is applied to create large enough tension of the thread 10, the thread 10 will be broken. Therefore, the resilient arm 321 will form a buffering element to reduce the tension and to minimize the sudden pulling force at the thread 10.

[0044] In order to allow the mid-portion of the thread 10 being easily coupled at the free end of the rotatable arm 32, the body 20 further comprises a thread coupling unit 24 for coupling the thread 10 with the rotatable arm 32. The thread coupling unit 24 comprises a folding tab 241, a tubular arm sleeve 242, and an end blocker 243.

[0045] The folding tab 241 is foldably coupled at the housing 21 at the upper side thereof to communicate with the through slot 23, wherein the folding tab 241 has an pusher arm 244 extended downwardly to the through slot 23. Preferably, the folding tab 241 is pivotally coupled with the housing 21, wherein the pusher arm 244 has a U-shaped configuration. When the folding tab 241 is pivotally and upwardly folded, the pusher arm 244 is driven to move frontwardly.

[0046] The arm sleeve 242 has a cavity to slidably and coaxially receive the rotatable arm 32 therein , wherein the arm sleeve 242 has an operation slot 245 indently formed at the outer circumferential side of the arm sleeve 242. The pusher arm 244 is engaged with the operation slot 245 to couple the arm sleeve 242 with the folding tab 241. The arm sleeve 242 is slidably supported in the housing 21 to encircle around the rotatable arm 32.

[0047] The end blocker 243 is coupled at the free end of the rotatable arm 32 and is blocked by the front end of the arm sleeve 242 to retain the free end of the rotatable arm 32 out of the cavity of the arm sleeve 242. In other words, the size of the end blocker 243 is larger than the diameter of the arm sleeve 242 to prevent the end blocker 243 being slid into the arm sleeve 242. At the normal position, the end blocker 243 is held at the front end of the arm sleeve 242 such that the free end of the rotatable arm 32 is retained in front of the arm sleeve 242.

[0048] When the folding tab 241 is folded upwardly, the arm sleeve 242 is pushed frontwardly via the pusher arm 244 so as to push the end blocker 243 frontwardly to expose the free end of the rotatable arm 32 out of the through slot 23. Therefore, the user is able to easily access the rotatable arm 32 to couple the mid-portion of the thread 10 thereat. When the folding tab 241 is downwardly folded flat to align with the upper side of the housing 21, the arm sleeve 242 is moved rearwardly. Therefore, the end blocker 242 is move rearwardly to move the free end of the rotatable arm 32 back into the through slot 23. In other words, the free end of the rotatable arm 32 is hidden within the housing 21.

[0049] It is worth mentioning that when the resilient arm 321 is stretched to prolong the length thereof by the resilient force in response to the tension of the thread 10, the end blocker 243 is also pulled out of the through slot 23. However, the arm sleeve 242 is remained at its normal position without being pushed frontwardly.

[0050] FIGS. 6A and 6B illustrate an alternative mode of the thread coupling unit 24A for coupling the thread 10 with the rotatable arm 32, wherein the thread coupling unit 24A comprises an elongated operation slot 241A and an operation tab 242A.

[0051] The operation slot 241 A is formed at the bottom side of the housing 21 and is aligned with the through slot 23 thereat. In particular, the operation slot 241A is a through slot to communicate the interior of the housing 21.

[0052] The operation tab 242A which is coupled with the rotatable arm 32 and is slidably engaged with the operation slot 241A. In particular, the operation tab 242A has an inner portion coupled with the rotatable arm 32 and an outer portion slidably engaged with the operation slot 241A. In other words, when the outer portion of the operation tab 242A is slid along the operation slot 241A, the rotatable arm 32 is driven to slide correspondingly.

[0053] As shown in FIG. 6A, the free end of the rotatable arm 32 is hidden within the housing 21. When the outer portion of the operation tab 242A is slid frontwardly along the operation slot 241A, the rotatable arm 32 is driven to slide frontwardly until the free end of the rotatable arm 32 exposes out of the through slot 23 as shown in FIG. 6B. Therefore, the user is able to easily access the rotatable arm 32 to couple the mid-portion of the thread 10 thereat. When the outer portion of the operation tab 242A is slid rearwardly along the operation slot 241A, the rotatable arm 32 is driven to slide rearwardly such that the free end of the rotatable arm 32 is moved back into the through slot 23 as shown in FIG. 6A.

[0054] As shown in FIGS. 2 and 3, the rotatable arm 32 further comprises a driving arm 322 rearwardly extended from the resilient arm 321 to operatively couple with the motorized unit 312 of the powering unit 31. In particular, the driving arm 322 is coupled to the resilient arm 321 end-to-end. Accordingly, in order to operatively couple the rotatable arm 32 with the motorized unit 312 of the powering unit 31, a drive gear unit 323 is provided to operatively link the driving arm 322 with the output shaft of the motorized unit 312 as shown in FIGS. 3 and 5. Therefore, the reciprocatingly rotational power is transmitted from the output shaft to the driving arm 322 in order to drive the resilient arm 321 to rotate. It is appreciated that the rotatable arm 32 can be embodied as the output shaft that the motorized unit 312 generates the reciprocatingly rotational power directly to the rotatable arm 32.

[0055] Accordingly, the drive gear unit 323 comprises a first gear coupled at the shaft of the motorized unit 312 and a second gear couple at the driving arm 322 of the rotatable arm 32, wherein the first and second gears are meshed with each other to transmit the reciprocatingly rotational power from the motorized unit 312 to the rotatable arm 32.

[0056] In order for the user to couple the thread with the epilation apparatus, the present invention further comprises a thread unit 40 to incorporate with the thread 10. The thread unit 40 has two thread slots 41 indentedly provided at the two free ends of the holding arms 22 respectively, two thread couplers 42 provided at the free ends of the thread 10 to detachably couple with the holding arms 22 respectively, and a thread retainer 43 provided at the mid-portion of the thread 10 to detachably couple with the rotatable arm 32.

[0057] Each of the thread couplers 42 is embodied as an enlarged coupling element preferably tied at the respective free end of the thread 10, wherein a size of the thread coupler 42 is larger than a width of the thread slot 41, such that when the thread 10 is held along the thread slot 41, the thread coupler 42 will retain the thread 10 at the thread slot 41 by the tension of the thread 10, so as to detachably couple the free end of the thread 10 at the corresponding free end of the holding arm 22.

[0058] The thread retainer 43 is provided at the mid-portion of the thread 10, preferably at the mid-point of the thread 10. The thread retainer 43 is embodied as a retaining ring to couple with the free end of the rotatable arm 32. According to the preferred embodiment, the free end of the resilient arm 321, as a compression spring, forms a hook end to engage with the thread retainer 43 so as to hold the mid-portion of the thread 10 in position.

[0059] Alternatively, the thread retainer 43A can be integrally formed at the free end of the rotatable arm 32 as shown in FIG. 6B, wherein the thread 10 can pass through the thread retainer 43A to hold the mid-portion of the thread 10 in position. It is worth mentioning that when two ends of the thread 10 are held at the free ends of the holding arm 22 respectively, the mid-portion of the thread 10 will be self-adjusted to be held by the thread retainer 43A.

[0060] In order to use the epilation apparatus, the present invention further provides a method of removing hair the epilation apparatus which comprises the following steps.

[0061] (1) Couple two free ends of the thread 10 at two free ends of the holding arms 22 respectively. According to the preferred embodiment, the free ends of the thread 10 are detachably coupled at two free ends of the holding arms 22 by the thread couplers 42.

[0062] (2) Couple the mid-portion of the thread 10 at the free end of the rotatable arm 32. According to the preferred embodiment, the mid-portion of the thread 10 is detachably coupled at the free end of the rotatable arm 32 by the thread retainer 43.

[0063] Accordingly, in the step (2), the folding tab 241 is folded to expose the free end of the rotatable arm 32. Therefore, the user is able to couple the thread retainer 43 to the rotatable arm 32 easily. Once the engagement therebetween is completed, the folding tab 241 can be folded back on the upper side of the housing 21.

[0064] It is worth mentioning that after the mid-portion of the thread 10 is detachably coupled at the rotatable arm 32, the thread 10 will form a V-shaped configuration and will define two equally length thread sections. Each thread section of the thread 10 is extended from the free end of one of the holding arms 22 to the free end of the rotatable arm 32.

[0065] (3) Apply the rotational force at the rotatable arm 32 to reciprocatingly rotate the rotatable arm 32 for twisting the thread 10 to simulate the threading motion. Accordingly, the rotatable arm 32 is powered by the motorized unit 312 to generate the reciprocatingly rotational power to the rotatable arm 32. When the rotatable arm 32 is rotated forwardly to twist the thread 10, the two thread sections of the thread 10 will be wound to form the wound portion starting from the rotatable arm 32 toward the free ends of the holding arms 22. When the rotatable arm 32 is kept rotating, the wound portion of the thread 10 will be increased towards the free ends of the holding arms 22. When the rotatable arm 32 is rotated backwardly, the wound portion of the thread 10 will be reduced towards the free end of the rotatable arm 32. The winding manner of the thread 10 will simulate the threading motion to remove the hair when the thread 10 is placed on the skin of the user as the traditional threading technique.

[0066] In the step (3), the method further comprises a step of applying the resilient force at the thread 10 to self-adjust a tension of the thread 10. Accordingly, the rotational force and the resilient force are applied to the thread 10 by the rotatable arm 32 at the same time. In other words, the resilient arm 321 will be driven to rotate and will be stretched out at the same time when the wound portion of the thread 10 is increased towards the free ends of the holding arms 22. It is worth mentioning that the free end of the resilient arm 321 may be pulled out of the front side 211 of the housing 21 through the through slot 23 when the wounding portion of the thread 10 reaches its maximum length, so as to prevent the thread 10 being broken by its tension. The resilient arm 321 will be driven to rotate and will be pulled back at the same time when the wound portion of the thread 10 is decreased towards the free end of the rotatable arm 32. In other words, the rotatable arm 32 is arranged to control the length of the wound portion of the thread 10. It is worth mentioning that the resilient force by the resilient arm 321 will be adjusted by the tension of the thread 10. When the tension of the thread 10 increases, i.e. increasing the length of the wound portion of the thread 10, the stretching force of the resilient arm 321 will be correspondingly increased. It is worth mentioning that the resilient force is applied perpendicular to the first side 211 of the body 20. In particular, the resilient force is aligned with the winding direction of the thread 10.

[0067] It is worth mentioning that after the threading operation is completed, the thread 10 should be removed from the epilation apparatus and disposed for one time use.

[0068] One skilled in the art will understand that the embodiment of the present invention as shown in the drawings and described above is exemplary only and not intended to be limiting.

[0069] It will thus be seen that the objects of the present invention have been fully and effectively accomplished. It embodiments have been shown and described for the purposes of illustrating the functional and structural principles of the present invention and is subject to change without departure from such principles. Therefore, this invention includes all modifications encompassed within the spirit and scope of the following claims.
