Description

[Technical Field]

[0001] The present invention relates to the technical field of massage equipment, and particularly to a reciprocating rotary massage comb with electrical stimulation function. [Background technology]

[0002] With the development of society and the improvement of living standards, people's demands for scalp health and head relaxation are increasing, and therefore various head massage devices have appeared, among which combs with massage functions can not only comb hair as a normal comb but also massage the scalp as a massager, are easy to hold, have diverse functions and are therefore popular with consumers. Such combs with massage functions generally incorporate a vibration massage function, and some products also have an electrical stimulation function, with the aim of promoting blood circulation in the scalp and relieving head fatigue through the synergistic effect of physical vibration and electrical stimulation.

[0003] Most of the common massage combs currently available on the market with vibration massage functions use a motor equipped with an eccentric block to achieve the vibration massage function. For example, Chinese Utility Model Patent CN217245467U discloses the following massage comb: A motor is fixedly connected within a housing, and an eccentric block is fixedly connected to the motor's output shaft. The center of the eccentric block is offset from the motor's output shaft. When the motor drives and rotates the eccentric block, centrifugal force is generated in the eccentric block. This centrifugal force drives the motor to vibrate along its radial direction. The motor transmits the vibrations to the comb needle assembly, causing it to vibrate. During the vibration process, the comb needle assembly repeatedly presses against the head, thereby massaging the head.

[0004] However, such vibration methods driven by a motor with an eccentric block have obvious limitations. First, because such vibration methods transmit vibrations to the comb needle assembly via radial vibrations of the motor body, they are unable to drive the comb teeth to rotate back and forth. Therefore, some users may feel a sense of "shaking" rather than a "massage," which may reduce the relaxing effect on the head. Second, such vibration methods drive the entire comb, causing it to vibrate together, which may generate a relatively loud noise that may be uncomfortable for the user. Furthermore, the hand holding the comb also vibrates significantly, making it uncomfortable to hold.

[0005] Therefore, how to improve the mechanical massage method of massage combs to provide a more comfortable massage feeling that better meets the needs of the human body has become a technical problem that needs to be solved urgently in the technical field. Summary of the Invention [Problem to be solved by the invention]

[0006] The purpose of this invention is to provide a reciprocating rotary massage comb with an electrical stimulation function that can solve the technical problems of conventional massage combs, which have the drawback of providing a less comfortable and effective massage due to the use of a motor equipped with an eccentric block to achieve vibration massage.

DETAILED DESCRIPTION OF THE INVENTION

[0020] In order to facilitate the understanding of those skilled in the art, the present invention will be further described below with reference to examples and drawings, and the contents mentioned in the embodiments are not intended to limit the present invention.

[0021] As shown in Figures 1 to 9, the reciprocating rotary massage comb with electrical stimulation function according to the present invention comprises an outer case 1, a control circuit board 2, a conductive comb mechanism 3, a conductive mechanism 4, an electrical stimulation module, a reciprocating rotary drive 5, and a power supply mechanism 6. The electrical stimulation module, the reciprocating rotary drive 5, and the power supply mechanism 6 are all connected to the control circuit board 2. One end of the conductive mechanism 4 is connected to the electrical stimulation module and the other end is connected to the conductive comb mechanism 3. The output shaft 51 of the reciprocating rotary drive 5 is connected to the conductive comb mechanism 3. The reciprocating rotary drive 5 drives the conductive comb mechanism 3 to perform a small-angle reciprocating rotation around the output shaft 51. Preferably, the small-angle reciprocating rotation occurs in a plane perpendicular to the output shaft 51, with a rotation angle of 4° to 20° and a reciprocating rotation frequency of 20 to 60 times per second. One reciprocating rotation is completed by rotating from the starting point to the end point and then from the end point to the starting point. Specifically, the reciprocating rotary drive unit 5 is an existing drive unit that can realize small-angle reciprocating rotation. For example, the ultra-small reciprocating oscillator disclosed in Chinese Utility Model Patent CN206195579U and the moving magnet type small-angle reciprocating rotary motor disclosed in Chinese Utility Model Patent CN218514265U can both be used as the reciprocating rotary drive unit 5 of the present application. Therefore, a detailed description of the specific structure of the reciprocating rotary drive unit 5 will be omitted here.

[0022] In actual use, the user activates the massage comb and brings the conductive comb mechanism 3 into contact with the scalp. The conductive comb mechanism 3 is provided with multiple comb teeth (including multiple first comb teeth 310 and multiple second comb teeth 320). When the multiple comb teeth contact the scalp, a concave arc surface is formed together, which can adapt to the arc degree of the user's scalp and ensure that all of the multiple comb teeth can contact the scalp. The control circuit board 2 controls the reciprocating rotary drive unit 5 and / or the electrical stimulation module to be activated. The reciprocating rotary drive unit 5 drives the conductive comb mechanism 3 to rotate at a small angle. The electrical stimulation module outputs a current of a specific frequency and wavelength, which is conducted to the conductive comb-tooth mechanism 3 via the conductive mechanism 4. After the comb teeth contact the scalp and conduct, a weak current is generated, massaging the scalp and relieving scalp fatigue and tension. The reciprocating rotary drive device 5 and the electrical stimulation module may be activated simultaneously or independently, thereby meeting different user needs.

[0023] In this embodiment, the reciprocating rotary drive unit 5 drives the comb teeth on the conductive comb-tooth mechanism 3 to rotate back and forth over a small angle on the scalp, thereby achieving a massage effect similar to that of a person's fingers moving back and forth over the scalp, similar to the scratching sensation experienced by a massage. This mechanical massage method does not cause the user to feel a "shaking" sensation, allowing the head to be more relaxed during massage. Furthermore, the reciprocating rotary drive unit 5 drives the conductive comb-tooth mechanism 3 to rotate back and forth over a small angle via the output shaft 51. In other words, this mechanical massage method in this embodiment does not drive the entire massage comb to vibrate together. Compared to the vibration massage method driven by a motor with an eccentric block in the prior art, this not only effectively reduces noise during use of the massage comb, but also avoids the feeling of vibration in the user's hands holding the comb, thereby improving the user's comfort when using the massage comb.

[0024] Furthermore, as shown in FIG. 5 , the conductive mechanism 4 includes a positive conductive assembly 41 and a negative conductive assembly 42, the positive conductive assembly 41 includes a positive conductive spring 411 and a positive conductive elastic piece 412, the negative conductive assembly 42 includes a negative conductive spring 421 and a negative conductive elastic piece 422, one end of the positive conductive spring 411 is connected to the positive electrode of the output terminal of the electrical stimulation module and the other end is connected to the positive conductive elastic piece 412, the negative conductive spring 421 is connected to the negative electrode of the output terminal of the electrical stimulation module and the other end is connected to the negative conductive elastic piece 422, and the end of the positive conductive elastic piece 412 remote from the positive conductive spring 411 and the end of the negative conductive elastic piece 422 remote from the negative conductive spring 421 are both connected to the conductive comb tooth mechanism 3, respectively. In this embodiment, a positive conductive spring 411 and a positive conductive elastic piece 412 are used as the positive conductive assembly 41, and a negative conductive spring 421 and a negative conductive elastic piece 422 are used as the negative conductive assembly 42. Because the spring and elastic piece can be elastically deformed, when the positive conductive elastic piece 412 and the negative conductive elastic piece 422 follow the conductive comb tooth mechanism 3 and rotate back and forth at a small angle together, the ends of the positive conductive spring 411 and the negative conductive spring 421 that are connected to the electrical stimulation module do not move, thereby ensuring the stability of the connection of the positive conductive spring 411 and the negative conductive spring 421 to the electrical stimulation module.

[0025] 5 and 8 , the positive conductive assembly 41 and the negative conductive assembly 42 are respectively mounted on opposite sides of the output shaft 51, and an insulating bushing 52 is further provided around the output shaft 51. The end of the positive conductive elastic piece 412 remote from the positive conductive spring 411 and the end of the negative conductive elastic piece 422 remote from the negative conductive spring 421 are both mounted in the insulating bushing 52. In this embodiment, the insulating bushing 52 is provided on the output shaft 51, and the positive conductive elastic piece 412 and the negative conductive elastic piece 422 are mounted in the insulating bushing 52. On the one hand, the insulating bushing 52 insulates the positive conductive elastic piece 412 and the negative conductive elastic piece 422 from each other. On the other hand, the output shaft 51 is connected to the conductive comb mechanism 3. With this arrangement, when the conductive comb mechanism 3 is attached to the insulating bushing 52 of the output shaft 51, the conductive comb mechanism 3 and the conductive mechanism 4 can be connected.

In this embodiment, the first conductive comb tooth assembly 31 and the second conductive comb tooth assembly 32 are installed and connected to the positive conductive elastic piece 412 or the negative conductive elastic piece 422, respectively, so that the multiple first comb teeth 310 and the multiple second comb teeth 320 form electrodes of different polarities, which makes it easy to contact the scalp and form a conductive circuit.

[0027] 1, 5 and 8, the conductive comb mechanism 3 further includes an insulating base plate 33, the first conductive support and the second conductive support are both installed on the insulating base plate 33, an insulating sleeve 331 is provided at the center of the insulating base plate 33 to protrude upward, a first contact block 313 is provided on the first conductive support in a direction close to the insulating sleeve 331, and a second contact block 313 is provided on the second conductive support in a direction close to the insulating sleeve 331. A contact block 323 is extended, and the first contact block 313 and the second contact block 323 are installed at an interval within the insulating sleeve 331, and the first contact block 313 and the second contact block 323 are installed through the wall of the insulating sleeve 331, and the insulating sleeve 331 is fitted on the outside of the insulating bush 52, and one of the first contact block 313 and the second contact block 323 contacts the positive electrode conductive elastic piece 412, and the other contacts the negative electrode conductive elastic piece 422. In this embodiment, by installing an insulating sleeve 331, the insulating sleeve 331 can be fitted around the outside of the insulating bush 52, thereby realizing the connection between the conductive comb tooth mechanism 3 and the output shaft 51. Furthermore, the first contact block 313 and the second contact block 323 are installed through the wall of the insulating sleeve 331, so that by fitting the insulating sleeve 331 around the outside of the insulating bush 52, the first contact block 313 and the second contact block 323 can be connected to the positive electrode conductive elastic piece 412 and the negative electrode conductive elastic piece 422, respectively. Furthermore, by installing in this manner, the conductive mechanism 4 is not exposed, improving safety during use.

[0028] 8 , the first conductive support includes an outer ring member 311 and a number of first support sheets 312, which are spaced apart inside the outer ring member 311 and connected to the outer ring member 311. The second conductive support includes an inner ring member 321 and a number of second support sheets 322, which are spaced apart outside the inner ring member 321 and connected to the inner ring member 321. In this embodiment, the outer ring member 311 is connected to a number of first support sheets 312, thereby connecting the conductive mechanism 4 to the outer ring member 311 or one of the first support sheets 312, thereby achieving electrical continuity throughout the first conductive support. The inner ring member 321 is connected to a number of second support sheets 322, thereby connecting the conductive mechanism 4 to the inner ring member 321 or one of the second support sheets 322, thereby achieving electrical continuity throughout the second conductive support.

In this embodiment, a number of first support sheets 312 and a number of second support sheets 322 are arranged alternately and at intervals along the circumferential direction of the outer ring member 311. On the one hand, the space of the massage comb can be rationally utilized to arrange the first support sheets 312 and the second support sheets 322, and the area of ​​the first support sheets 312 and the second support sheets 322 can be increased as much as possible within the limited space range, thereby effectively increasing the contact area between the conductive comb tooth mechanism 3 and the human scalp; on the other hand, the first support sheets 312 and the second support sheets 322 have a petal-like shape, improving the aesthetics.

[0030] Furthermore, the conductive comb tooth mechanism 3 is integrally injection molded using a two-color injection molding process, which not only improves the production efficiency of the conductive comb tooth mechanism 3 but also improves the connection stability between the first conductive comb tooth assembly 31, the second conductive comb tooth assembly 32, and the insulating base plate 33.

In this embodiment, the conductive comb tooth mechanism 3 and the output shaft 51 are detachably connected, which on the one hand makes it easy for the user to remove and clean the conductive comb tooth mechanism 3, and on the other hand makes it easy for the user to replace it with a different type of conductive comb tooth mechanism 3 or replace it with a non-conductive comb tooth mechanism as needed, as shown in FIG. 10 .
