Description

Technical Field

[0001] The present invention relates to a tapping device.

Background Art

[0002] Conventionally, it has been known to impregnate a non-woven fabric such as cotton with lotion and perform patting (the act of continuously tapping the skin). By using this non-woven fabric, the amount of lotion permeating into the stratum corneum can be increased.

[0003] Also, conventionally, devices for gently tapping (tapping) human skin have been known. Patent Document 1 discloses a tapping type beauty device that gently and rhythmically taps (taps) facial skin with a tapping member about the size of a fingertip.

Summary of the Invention

Problems to be Solved by the Invention

[0005] When impregnating a non-woven fabric with lotion and performing patting (the act of continuously tapping the skin), for example, place the center of the non-woven fabric on the pad of the middle finger, and sandwich the end of the non-woven fabric with the middle finger, index finger, and ring finger to tap the skin. However, it is necessary and difficult to get used to tapping the skin while properly holding the non-woven fabric. Also, only simple patting with the pad of the middle finger can be performed. For example, while holding the non-woven fabric in the hand, it is not possible to tap with multiple fingers as is done in esthetics.

[0006] In the prior art, the striker of the tapping member rotates around the mounting portion. Since most of the tapping member is exposed from the housing of the device and the area where the tapping member moves is large, the tapping member may come into contact with objects other than the object to be tapped (tapped). Further, in the prior art, while holding the device by hand so that the striker strikes the skin with an appropriate strength, it is necessary to adjust the distance between the skin and the striker, and it is difficult to appropriately apply the striker to the skin while keeping the distance constant.

[0007] An object of one embodiment of the present invention is to provide a tapping device that can perform tapping safely and easily in close contact with the skin without the member performing the tapping coming into contact with objects other than the tapping target.

Means for Solving the Problems

[0008] The disclosed tapping device is a tapping device including a plurality of sliders each having a finger portion, a drive member that moves the slider in a first direction, and a pressing member that presses the slider in a second direction opposite to the first direction, and further includes a cover that covers the plurality of finger portions of the plurality of sliders.

Effects of the Invention

[0009] The tapping device can be brought into close contact with the skin, and tapping can be performed safely and easily without the member performing the tapping coming into contact with objects other than the tapping target.

Embodiments for Carrying Out the Invention

[0011] The present embodiment will be described below with reference to the drawings.

[0012] First, the appearance of the tapping device 1 will be described.

[0013] FIG. 1A is a front view of the tapping device 1 according to the present embodiment. FIG. 1B is a side view of the tapping device 1 according to the present embodiment. First, the directions will be described. A coordinate axis is shown in FIG. 1. In the side view of FIG. 1A and the front view of FIG. 1B, the longitudinal direction of the tapping device 1 (the left - right direction in FIGS. 1A and 1B) is defined as the X - axis, the right direction is the +X direction, and the left direction is the -X direction. In the front view of FIG. 1B, the width direction of the tapping device 1 (the up - down direction in FIG. 1B) is defined as the Y - axis, the up direction is the +Y direction, and the down direction is the -Y direction. In the side view of FIG. 1A, the height direction of the tapping device 1 (the up - down direction in FIG. 1A) is defined as the Z - axis, the up direction is the +Z direction, and the down direction is the -Z direction. The tapping target is tapped along the Z - axis so as to be parallel to the X - Y plane.

[0014] The tapping device 1 includes a gripping portion 100 and a tapping head portion 200.

[0015] The gripping portion 100 is the part that a user holds by hand when using the tapping device 1. The gripping portion 100 of the present embodiment is provided with a power switch 110. Further, it may be provided with an operation portion such as a setting switch other than the power switch 110 and a display portion indicating the operation state. The gripping portion 100 of the present embodiment incorporates a part of a control board 40, a battery 50, and a tapping mechanism portion 400, which will be described later.

[0016] The tapping head portion 200 is the part that is pressed against an object such as the skin to be tapped by the user. The tapping head portion 200 of the present embodiment incorporates a part of the tapping mechanism portion 400, which will be described later.

[0017] The tapping device 1 according to the present embodiment further includes a cover 300 at the portion that is pressed against the tapping target.

[0018] Next, the configuration of the tapping device 1 will be described.

[0019] FIG. 2 is an exploded perspective view of the tapping device 1 according to the present embodiment.

[0020] The tapping device 1 includes a housing 10. The housing 10 is formed by connecting a top cover 11 and a bottom cover 12. A gripping portion 100 is provided on the housing 10. A frame portion 15 is provided at the tip portion of the bottom cover 12. The frame portion 15 constitutes a part of the tapping head portion 200 and is provided so as to cover the periphery of the side surface of a finger portion 411 described later. A cover 300 is attached to the frame portion 15.

[0021] The housing 10 includes a mechanical box 20 inside the housing 10. The mechanical box 20 is formed by connecting a mechanical box top cover 21 and a mechanical box bottom cover 22. The mechanical box 20 incorporates a part of the tapping mechanism portion 400. Sound is generated when the tapping mechanism portion 400 operates. For example, sound is generated from a motor which is a driving portion 423 of the tapping mechanism portion 400. By incorporating the tapping mechanism portion 400 in the mechanical box 20, the tapping mechanism portion 400 is doubly surrounded by the mechanical box 20 and the housing 10, so that it is possible to prevent sound from leaking outside the housing 10. Therefore, the tapping device 1 can be made quieter.

[0022] Also, the mechanical box 20 is installed in the housing 10 via a cushioning material 30. Vibration is generated when the tapping mechanism portion 400 operates. By interposing the cushioning material 30, it is possible to prevent the vibration from being transmitted to the housing 10. Furthermore, it is possible to prevent the sound of the tapping mechanism portion 400 from being transmitted outside the housing 10. Therefore, by installing the mechanical box 20 of the present embodiment as described above, the tapping device 1 can be made quieter.

[0023] The housing 10 includes a control board 40 and a battery 50 inside the top cover 11 and the bottom cover 12. The control board 40 includes a circuit and the like for driving and controlling the driving portion 423 of the tapping mechanism portion 400. The battery 50 supplies power for driving the driving portion 423 of the tapping mechanism portion 400 and the control board 40 respectively.

[0024] Next, the tapping mechanism section 400 of the tapping device 1 will be described. The tapping device 1 performs a tapping operation by the tapping mechanism section 400.

[0025] FIG. 3 is a perspective view of the tapping mechanism section 400 of the tapping device 1 according to the present embodiment. FIG. 4 is a perspective view of the slider 410 of the tapping device 1 according to the present embodiment.

[0026] The tapping mechanism section 400 includes a slider 410, a drive member 420, and a pressing member 430.

[0027] Each member of the tapping mechanism section 400 will be described.

[0028] The slider 410 includes a finger portion 411 and a connecting member 412. The tapping device 1 of the present embodiment includes three sliders 410. In the tapping device 1 of the present embodiment, the three sliders 410 are arranged side by side in a straight line horizontally. By arranging them in a straight line, it is possible to tap like a human finger.

[0029] The finger portion 411 is a member that taps the skin through the cover 300 when performing tapping. The shape of the finger portion 411 is imitated from the shape of a human finger. Specifically, it has a substantially rectangular shape when viewed from the front. A part of the cross-section of the finger portion 411 is preferably a part of a substantially ellipse imitating the shape of the belly of a finger. In the present embodiment, the finger portion 411 is formed of a single member, but it may be formed using a plurality of members. For example, it may be formed by combining a rectangular parallelepiped and a rounded member.

[0030] Note that the finger portion 411 may be detachable from the connecting member 412. By making it detachable, the user can select a finger portion 411 with a preferred shape or a finger portion 411 with a shape preferable for the treatment.

[0031] The connecting member 412 is a member that connects the finger portion 411 and a cam receiving portion 421, which will be described later, at a predetermined interval.

[0032] Next, the drive member 420 will be described. The drive member 420 includes a cam receiving portion 421, a camshaft 422, and a drive portion 423.

[0033] The cam receiving portion 421 is a member that engages with a cam 425, which will be described later. One cam receiving portion 421 is provided for each slider 410. The tapping device 1 of the present embodiment includes a total of three cam receiving portions 421. The cam receiving portion 421 is attached on the side opposite to the finger portion 411 of the connecting member 412.

[0034] The camshaft 422 is a member that rotates the cam 425. The camshaft 422 includes the same number of cams 425 as the sliders 410. The camshaft 422 is rotated by the drive portion 423. As a result, the cam 425 provided on the camshaft 422 rotates. The rotating cam 425 engages with the cam receiving portion 421 and moves the cam receiving portion 421 in the Z direction (the first direction).

[0035] The drive portion 423 is a member that rotates the camshaft 422. In the present embodiment of FIG. 3, specifically, it is a motor. A speed reducer may be provided between the drive portion 423 and the camshaft 422. Note that the rotation speed of the drive portion 423 or the camshaft 422 may be adjustable. For example, by increasing the rotation speed, tapping can be performed at a fast rhythm, or by decreasing the rotation speed, tapping can be performed at a slow rhythm.

[0036] Next, the pressing member 430 will be described.

[0037] The pressing member 430 is a member that presses the slider 410 in the -Z direction (the second direction), which is the direction opposite to the Z direction (the first direction). In the present embodiment, a compression spring provided between the slider 410 and the mechanical box stop cover 21 is used as the pressing member 430. The maximum force with which the compression spring of the present embodiment presses the slider 410, that is, the force of the compression spring (maximum load) when the compression spring is most compressed when the tapping device 1 is operated, is desirably 1 to 10 N. Further, it is desirably 3 to 4 N. By setting the force to press the slider 410 in such a manner, the tapping strength that reproduces tapping by a human finger is achieved.

[0038] The pressing member 430 may be any member that can press the slider 410, for example, an elastic member such as a spring or rubber. Regarding the spring, in the present embodiment, the pressing member 430 uses a compression spring, but a tension spring may be used as the pressing member 430 to pull the slider 410 from below to press it.

[0039] Next, the damper 500 will be described.

[0040] FIG. 5 is a cross-sectional perspective view of the damper 500 of the tapping device 1 according to the present embodiment. The damper 500 is a member that attenuates the speed when the slider 410 moves in the -Z direction (the second direction), which is the direction opposite to the Z direction (the first direction).

[0041] The tapping device 1 of the present embodiment includes a damper 500 for each slider 410. The damper 500 includes a piston 510, an O-ring 520, and a cylinder 530.

[0042] The piston 510 of the present embodiment is integrated with the cam receiving portion 421. The shape of the piston 510 is substantially rod-shaped. A groove with a semicircular cross-section is formed on the outer peripheral surface of the tip side of the piston 510. Approximately half of the cross-section of the O-ring 520 is inserted and mounted in the groove.

[0043] The shape of the cylinder 530 in this embodiment is a substantially cylindrical shape with a bottom. The cylinder 530 in this embodiment is formed on the mechatronics box bottom cover 22.

[0044] The piston 510 is inserted into the cylinder 530. At that time, the O-ring 520 is in close contact with the semi-circular groove of the cross-section of the piston 510 and the inner surface of the cylinder 530. Thereby, the space surrounded by the piston 510, the O-ring 520, and the cylinder 530 is in a sealed state. When the piston 510 is pushed into the cylinder 530 during tapping, the air in the cylinder 530 is compressed, so that the speed of the slider 410 can be attenuated. In this way, the damper 500 operates as an air damper.

[0045] When the slider 410 is stopped in a high-speed state, a relatively large impact sound is generated. By providing the damper 500, the slider 410 can be stopped in a state where its speed is appropriately attenuated. Thereby, the impact sound can be reduced. Therefore, the tapping device 1 can be made quieter.

[0046] Note that, as the damper 500 in this embodiment, an air damper is adopted, but a damper other than the air damper may be adopted. For example, a hydraulic type may be used. Also, an elastic member such as rubber or a spring may be used.

[0047] Next, the cover 300 will be described with reference to FIGS. 1, 2, and 6.

[0048] FIG. 6 is a cross-sectional view of the tapping device 1 according to this embodiment. FIG. 6 is a cross-sectional view taken along the line A-A of FIG. 1B. Note that FIG. 6 shows a cross-section in the vicinity of the tapping head portion 200. FIG. 6 shows a state where all the sliders 410 are stationary (stationary state) and the finger portion 411 is at the lowest point.

[0049] The tapping device 1 of this embodiment includes three sliders 410. Each slider 410 includes a finger portion 411. The cover 300 is attached so as to cover the plurality of finger portions 411.

[0050] As shown in FIG. 6, the cover 300 includes a plurality of convex portions 310 corresponding to the finger portions 411, and a cover frame portion 320 that surrounds the convex portions 310 and covers the frame portion 15. The cover 300 is attached by fitting the cover frame portion 320 of the cover 300 and the frame portion 15 of the bottom cover 12. Further, the finger portion 411 is inserted from the side opposite to the tapping target side of the convex portion 310.

[0051] Here, the positional relationship between the finger portion 411 and the frame portion 15 of the tapping device 1 of this embodiment will be described. As will be described later, the slider 410 is in a state where it does not move in the Z direction and the slider 410 is stationary (stationary state) when the cam receiving portion 421 of the driving member 420 and the cam 425 are not engaged. In such a stationary state, the finger portion 411 protrudes by a distance a toward the tapping target side from the frame portion 15 as shown in FIG. 6. In the tapping device 1 of this embodiment, the distance a is about 3 mm.

[0052] As described above, corresponding to the fact that the finger portion 411 protrudes toward the tapping target side from the frame portion 15, the convex portion 310 protrudes by a distance b toward the tapping target side from the cover frame portion 320. In the tapping device 1 of this embodiment, the distance b is about 3 mm, the same as the distance a. Note that the distance a and the distance b may be the same distance or different distances.

[0053] The combined thickness of the epidermis and dermis of human skin is about 2.2 mm. With the cover surface of the cover frame portion 320 applied to the skin during driving, the convex portion 310 can be pushed in by about 3 mm. As a result, by protruding the convex portion 310 by about 3 mm, the convex portion 310 can be pushed into the dermis layer including capillaries and lymphatic vessels. By pushing it into the dermis, it becomes possible to effectively promote the circulation of body fluids.

[0054] In the tapping device 1 of this embodiment, since the frame portion 15 and the cover frame portion 320 are provided, in the usage state by driving the finger portion 411 so that the cover frame portion 320 touches the skin, the distance between the skin and the finger portion 411 can be easily adjusted. Further, since the frame portion 15 and the cover frame portion 320 are provided, it is possible to prevent the cover frame portion 320 from pressing too strongly on the finger portion 411 against the skin.

[0055] The cover 300 is preferably a cover that does not permeate liquid, that is, a liquid-impermeable cover. The material of the cover 300 is preferably flexible since it comes into contact with the skin. For example, the material of the cover 300 is rubber, elastomer, etc. In particular, it is preferably urethane or silicone. By using the flexible cover 300, it is possible to approximate the feeling of human skin when in contact.

[0056] The cover 300 of the tapping device 1 of this embodiment covers a plurality of finger portions 411 with one cover 300. By doing so, the number of parts can be reduced as compared with covering each finger portion 411 with an individual cover. Further, by covering the space between the finger portions 411 with a cover, it is possible to improve water resistance and prevent something from being caught in the gaps between the finger portions 411.

[0057] The cover 300 of the tapping device 1 of this embodiment is attached by fitting the cover frame portion 320 into the frame portion 15, and thus can be removed. Since the cover 300 can be removed, for example, it is possible for the user to change the cover 300 or use a cover 300 with different specifications such as thickness. Further, since it can be removed, the cover 300 can be removed and washed when it gets dirty.

[0058] In addition, the surface of the cover 300 of the present embodiment is not limited to a smooth surface (curved surface). For example, it may be provided with protrusions on the surface. Also, the surface of the cover 300 may be changed according to the tapping application. For example, a smooth-surfaced cover 300 may be used during daily skin care, and a cover 300 with protrusions may be used during massage.

[0059] Next, a sheet 700 used in combination with the tapping device 1 and a mounting ring 600 for mounting the sheet 700 will be described.

[0060] FIG. 7 is a front view showing a state in which the sheet 700 and the mounting ring 600 of the tapping device 1 are mounted. As described in the prior art, it is known that applying a cosmetic base such as lotion using a non-woven fabric has the effect of increasing the penetration amount of the lotion into the stratum corneum. In the tapping device 1 of the present embodiment, tapping can be performed while using a sheet 700 containing a cosmetic base. The sheet 700 is attached onto the cover 300 of the tapping device 1 by the mounting ring 600.

[0061] When performing tapping, it is preferable that the cosmetic base is impregnated into the sheet 700. Also, the cosmetic base may be applied to the sheet surface of the sheet 700.

[0062] The sheet 700 may be any that can be impregnated or coated with a cosmetic base. For example, it is preferably a sheet having a three-dimensional porous structure, particularly preferably any one of a non-woven fabric, a sponge, and a cloth. In particular, a non-woven fabric containing cotton is preferable.

[0063] The cosmetic base applied simultaneously with the tapping device 1 of the present embodiment preferably contains a water-soluble active ingredient. Further, the water-soluble active ingredient is preferably a moisturizing ingredient or a whitening ingredient. The moisturizing ingredient preferably contains glycerin. The whitening ingredient preferably contains any one of tranexamic acid, a vitamin C derivative, arbutin, potassium 4-methoxysalicylate, and nicotinamide.

[0064] Since the sheet 700 is attached to the tapping device 1 of the present embodiment, there is no need to hold the sheet 700 by hand. Therefore, with one hand operation of the tapping device 1, it is possible to tap while applying the cosmetic base to the skin.

[0065] Since the tapping device 1 of the present embodiment performs tapping by a plurality of sliders 410, it is possible to perform tapping such as a beautician's finger tapping simultaneously with padding by a non-woven fabric. Thereby, a higher beauty effect and a comfort that cannot be felt by one's own hand can be realized.

[0066] Next, the operation of the tapping mechanism unit 400 will be described.

[0067] FIGS. 8A, 8B, and 8C are diagrams for explaining the tapping operation of the slider 410 of the tapping device 1 according to the present embodiment.

[0068] The camshaft 422 rotates by the drive unit 423. When the camshaft 422 rotates, the cam 425 rotates. In FIG. 8, the cam 425 rotates counterclockwise (in the direction of arrow R).

[0069] FIG. 8A is a diagram of a state before the cam 425 and the cam receiving portion 421 are engaged. Since the slider 410 is pressed in the -Z direction (the second direction), which is the direction opposite to the Z direction (the first direction), by the pressing member 430, the finger portion 411 is at the lowest point. And it is in contact with the skin S to be tapped via the cover 300. Note that the cover 300 and the sheet 700 are omitted in FIGS. 8A, 8B, and 8C.

[0070] FIG. 8B is a view of the state in which the cam 425 and the cam receiving portion 421 are engaged. When the cam 425 is driven, the cam 425 and the cam receiving portion 421 are engaged. When the cam 425 and the cam receiving portion 421 are engaged, as the cam 425 rotates, the slider 410 moves in the Z direction (the first direction). The spring which is the pressing member 430 is compressed and elastic energy is accumulated.

[0071] FIG. 8C is a view of the state immediately after the engagement between the cam 425 and the cam receiving portion 421 is disengaged. When the cam 425 rotates in the state where the cam 425 and the cam receiving portion 421 are engaged, the engagement is disengaged. When the engagement is disengaged, the slider 410 linearly moves in the -Z direction (the second direction), which is the direction opposite to the Z direction (the first direction), as the elastic energy accumulated in the spring which is the pressing member 430 is released. Then, it moves and the finger portion 411 collides with the skin S to be tapped to perform tapping.

[0072] Here, the influence of the force applied to the skin will be described. For example, when a force is applied to the skin in the lateral direction by a roller or the like, it may damage the junction between the epidermis and the dermis and cause sagging and spots. Since the striking member of the prior art also rotates around the attachment portion in the prior art, it is difficult to strike the skin perpendicularly. The slider 410 of the tapping device 1 of the present embodiment moves linearly. Therefore, when tapping the skin without applying a force in the lateral direction to the skin, a force can always be applied perpendicularly to the skin. Therefore, the tapping device 1 of the present embodiment can tap the skin without damaging the junction between the epidermis and the dermis which causes sagging and spots during tapping.

[0073] In the tapping mechanism portion 400 of the present embodiment, after the engagement between the cam 425 and the cam receiving portion 421 is disengaged, tapping is performed by the repulsive force of the spring which is the pressing member 430. Therefore, the skin can be tapped with substantially constant strength. Further, even if the rotation speed of the drive portion 423 is changed, the tapping strength does not change and tapping can be performed with a constant strength.

[0074] Further, for example, when forcibly moving a slider as in a cam mechanism or a crank mechanism using a plate cam and a contactor, if a force is applied to the slider in the direction opposite to the moving direction, the operation may stop or, in some cases, malfunction. Also, the slider will be strongly pressed against the skin in proportion to the force pressing the slider against the skin.

[0075] In the tapping mechanism unit 400 of the present embodiment, for example, even if the cover 300 is pressed against the skin to push the slider 410 in the Z direction, it is possible to move in the Z direction against the force of the pressing member 430. Therefore, even when the cover 300 is pressed against the skin, a failure of the tapping mechanism unit 400 can be prevented.

[0076] As shown in FIG. 3, the tapping device 1 of the present embodiment includes three sliders 410. In the present embodiment, tapping is sequentially performed in the order of the sliders 410 arranged in sequence starting from the slider 410 close to the drive unit 423. By tapping in such a manner, it is possible to tap in a way that simulates a person tapping with a finger in sequence. Also, by tapping in sequence, a continuous and constant pressure stimulus can be applied to the skin.

[0077] Note that the order of tapping is not limited to the example of the present embodiment. For example, tapping may be sequentially performed in order starting from the slider 410 far from the drive unit 423. Also, instead of tapping in order, each slider 410 may tap individually with a timing shift from each other. Further, all the sliders 410 may tap simultaneously.

[0078] Also, in FIG. 8, the number of protrusions engaging with the cam receiving portion 421 of the cam 426 was one, but the number of protrusions is not limited to one. For example, two protrusions may be provided as in the cam 426 of FIG. 9, or three or more protrusions may be provided. Also, it is preferable to determine the rotational speed of the above-described drive unit 423 or camshaft 422 and the number of protrusions of the cam 425 so as to have a rhythm that reproduces a person's tapping.

[0079] Next, the usage method of the tapping device 1 will be described.

[0080] FIG. 10 is a diagram for explaining the usage method of the tapping device 1 according to the present embodiment.

[0081] The tapping device 1 is used according to the following procedure.

[0082] (1) Incorporate the cosmetic base into the sheet 700 (for example, a cotton non-woven fabric). (2) Attach the sheet 700 to the tapping device 1. (3) Turn on the power of the tapping device 1. (4) Bring the tapping head portion 200 of the tapping device 1 into close contact with the central part of the face. (5) As shown in FIG. 10, slowly slide the tapping device 1 horizontally from the center of the face toward the outside. (6) Repeat (5) several times while changing the location. (7) Turn off the power of the tapping device 1.

[0083] In this way, tapping can be performed using the tapping device 1 of the present embodiment.

[0084] Next, the features of the tapping device 1 of the present embodiment will be summarized.

[0085] In the tapping device 1 of the present embodiment, the tapping mechanism portion 400 is housed inside the housing 10 and the cover 300. Therefore, since the operating portion of the tapping mechanism portion 400 is not exposed to the outside and does not come into contact, it can be used safely.

[0086] Further, the tapping device 1 of the present embodiment is used with the cover 300 in close contact with the skin. Therefore, when using the tapping device 1, it is not necessary to adjust the distance between the skin and the tapping element as in the prior art, and it is easy to perform alignment. Therefore, tapping can be easily performed.

[0087] Furthermore, the cover 300 of the present embodiment is a liquid-impermeable cover. Therefore, even if a liquid base makeup agent is impregnated into the sheet 700 and used from the outside, the base makeup agent will not enter the inside of the housing. Also, it is possible to prevent malfunctions caused by liquid entering the inside of the tapping device 1.

[0088] In addition, since the tapping device 1 of the present embodiment can perform tapping by mounting a sheet 700 containing a base makeup agent, tapping using the base makeup agent in combination can be easily performed.

[0089] Note that the tapping device 1 of the present embodiment includes three sliders 410, but the number is not limited to three. Two or more are sufficient. For example, four sliders 410 may be used. Also, there may be one slider 410.

[0090] Moreover, in the tapping device 1 of the present embodiment, a plurality of sliders 410 are arranged linearly, but the arrangement of the sliders is not limited to being arranged linearly. For example, they may be arranged in a curved shape. Also, the tapping device 1 of the present embodiment has one row, but two or more rows may be arranged.
