[0032] DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] It should be noted that, in the description of the present invention, if the terms "first", "second", etc. appear, "first" and "second" are only used to facilitate the description of different components or names, and cannot be understood as indicating or implying a sequential relationship, relative importance, or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, if "and / or" appears in the full text, its meaning is to include three parallel solutions. Taking "A and / or B as an example", it includes solution A, or solution B, or solutions that meet both A and B.

[0035] The embodiment of the present utility model provides a physical therapy device for performing micro-current stimulation on the skin.

[0036] Please refer to Figures 1 to 6 The physiotherapy device includes a housing 10, electrodes 20, elastic conductors 30, conductive connectors 40, and a circuit board 50. Each of the electrodes 20, elastic conductors 30, and conductive connectors 40 is provided in pairs, one for each pair. The housing 10 is provided with two mounting holes 111, and the two electrodes 20 are mounted in the mounting holes 111 in a one-to-one correspondence. The electrodes 20 are used to contact the skin. The elastic conductors 30, conductive connectors 40, and circuit board 50 are located within the housing 10. The two conductive connectors 40 are respectively fixed to and electrically connected to the circuit board 50. The ends of the elastic conductor 30 elastically abut against the electrodes 20 and conductive connectors 40, respectively.

[0037] In this embodiment of the present invention, when the skin simultaneously contacts the two electrodes 20, the two electrodes 20, the two elastic conductors 30, the two conductive connectors 40, and the circuit board 50 together form a closed circuit, thereby providing microcurrent stimulation to the skin. The elastic conductors 30 and the conductive connectors 40 serve as conductive components, achieving electrical connection between the electrodes 20 and the circuit board 50.

[0038] Because the elastic conductor 30 is elastic, the elasticity of the elastic conductor 30 can be used to adapt the distance between the electrode 20 and the conductive connector 40. Even if there are certain assembly errors and processing errors or shaking, it can ensure that the elastic conductor 30 is in elastic contact with the electrode 20 and the conductive connector 40, that is, the elastic conductor 30 can always contact the electrode 20 and the conductive connector 40, and the conductive connector 40 is directly fixed on the circuit board 50. The relative position between the two is stable and has a stable electrical connection. In this way, it is equivalent to ensuring the stability of the electrical connection between the electrode 20 and the circuit board 50, thereby improving the user experience. Furthermore, it can also ensure that the electrode 20 and the conductive connector 40 are installed in the appropriate position and are not affected by the length of the elastic conductor 30.

[0039] Furthermore, in some cases, the elastic conductor 30 and the electrode 20 are elastically connected in a manner that does not require welding, which facilitates the disassembly and assembly of the two, and is conducive to the maintenance or replacement of related parts.

[0040] In some embodiments, the electrode 20 includes a top wall 21 and a side wall 22 disposed along the edge of the top wall 21. The top wall 21 covers the mounting hole 111, and the side wall 22 is at least partially located within the mounting hole 111. The end of the elastic conductor 30 abuts against the top wall 21 and also contacts the side wall 22. In this embodiment, the elastic conductor 30 is disposed near the edge of the electrode 20. By contacting the side wall 22 at the edge, the side wall 22 can limit the end of the elastic conductor 30, preventing the elastic conductor 30 from moving beyond the side wall 22 and escaping from the abutment with the top wall 21. The top wall 21 and the side wall 22 form a shape similar to the lid 70. On the one hand, they block the mounting hole 111, specifically by sealing the mounting hole 111, for example, using a sealant or a sealing ring. On the other hand, the side wall 22 extends into the mounting hole 111 to limit the electrode 20 and the elastic conductor 30 from moving radially along the mounting hole 111.

[0041] In addition, in other embodiments, a smaller groove may be provided at the bottom of the electrode 20 , and the end of the elastic conductor 30 may be embedded in the groove for positioning.

[0042] In some embodiments, the top wall 21 is meniscus-shaped and has two corners 24 at either end. The elastic conductor 30 is located near one of the corners 24. Because the top wall 21 is generally meniscus-shaped, it is narrower at the ends and wider in the middle. Consequently, the two corners 24 at the ends have a smaller space for confinement, allowing the elastic conductor 30 to be better confined to one of the two corners 24 and held by the side walls 22, reducing the risk of the elastic conductor 30 moving around. Furthermore, the wider middle portion of the top wall 21 provides a larger contact area with the skin, achieving better electrical stimulation therapy.

[0043] Of course, in other embodiments, the top wall 21 may be in a circular, square, irregular shape, or the like.

[0044] In some embodiments, a limiting flange 23 is further provided at one end of the side wall 22 away from the top wall 21. The limiting flange 23 abuts against the inner wall of the housing 10 to prevent the electrode 20 from upwardly disengaging from the mounting hole 111. Optionally, the limiting flange 23 may be annular and disposed around the mounting hole 111.

[0045] Furthermore, the outer surface of the shell 10 includes a coating surface 112, and the shell 10 is also formed with a liquid channel 113. The liquid outlet end of the liquid channel 113 passes through the coating surface 112, and the liquid inlet end of the liquid channel 113 is used to connect to the liquid container 80. In some embodiments, the coating surface 112 is a concave arc surface centered on the liquid outlet end, so that the liquid outlet end is located at the lowest point of the coating surface 112. The coating surface 112 is provided with mounting holes 111, and the two mounting holes 111 are distributed on two opposite sides of the liquid outlet end. Since the coating surface 112 is a concave arc surface, it can better fit the concave and convex characteristics of human skin. For example, it can be applied to the chin and electrically stimulated.

[0046] Specifically, the liquid in the liquid container 80, such as a sunscreen bottle, eye cream bottle, face cream bottle or essence bottle, enters the liquid channel 113 from the liquid inlet end, and finally flows out from the liquid outlet end to the coating surface 112 to be applied to the human skin. During the application process, since the human body contacts the two electrodes 20, a microcurrent can be generated to stimulate the skin to better absorb the skin care products.

[0047] In some embodiments, the electrode 20 is flush with the coating surface 112 , so as to ensure that the liquid outlet can fully contact the skin and avoid liquid residue at the liquid outlet.

[0048] Alternatively, in some embodiments, the electrodes 20 protrude from the coating surface 112, which greatly increases the likelihood of the electrodes 20 contacting the skin.

[0049] Please refer to Figure 2 、 Figure 7 and Figure 8In some embodiments, the housing 10 includes a top cover 11 and a base 12. The top cover 11 has a mounting hole 111. The base 12 covers the end of the top cover 11 away from the mounting hole 111. The base 12 is provided with a support member 123. The support member 123 is supported on the side of the conductive connector 40 away from the mounting hole 111. By providing the housing 10 with two parts, the top cover 11 and the base 12, the two parts can be processed separately, reducing the overall processing difficulty. In addition, by providing the support member 123 on the base 12 to support the conductive connector 40, the conductive connector 40 can be prevented from being elastically squeezed by the elastic conductor 30 and falling off. At the same time, the conductive connector 40 can be clamped by the elastic conductor 30 and the support member 123 to limit its position.

[0050] The top cover 11 is generally a hollow structure with an opening downward, and a mounting hole 111 is provided on the top surface of the top cover 11. The base 12 seals and covers the opening at the lower end of the top cover 11 to prevent water, dust, etc. from entering the space formed by the base 12 and the top cover 11.

[0051] Please refer to it again Figure 8 In some embodiments, the base 12 includes a covering portion 121 and a fixing protrusion 122. The covering portion 121 covers the top cover 11. The covering portion 121 can be generally disc-shaped or circular-shaped. The fixing protrusion 122 is connected to the covering portion 121 and is located in the space enclosed by the top cover 11 and the covering portion 121. The fixing protrusion 122 is hollow and has an opening 1221. The opening 1221 is located on the side of the covering portion 121 facing away from the top cover 11 and is used to insert the end of the liquid container 80. The fixing protrusion 122 is also provided with a connecting hole 1223 connected to its interior. The top cover 11 is provided with a liquid channel 113. One end of the liquid channel 113 passes through the outer side of the top cover 11, and the other end is connected to the connecting hole 1223. Specifically, the inner wall of the fixing protrusion 122 can be provided with an internal thread, and the end of the liquid container 80 can be provided with an external thread to match the internal thread. Alternatively, the end of the liquid container 80 can be directly inserted into the fixing protrusion 122 through the opening 1221 for a tight fit. When the liquid container 80 is mated with the base 12, the liquid channel 113 communicates with the liquid container 80 through the communication hole 1223. The liquid in the liquid container 80, such as sunscreen, eye cream, face cream, essence, or other skin care products, flows out of the liquid channel 113 onto the application surface 112 and acts on the user's skin.

[0052] In some embodiments, the support member 123 is formed on the fixing protrusion 122. Specifically, the support member 123 is disposed at one end of the fixing protrusion 122 close to the top wall 21, and a side of the support member 123 away from the fixing protrusion 122 supports the conductive connector 40. In other embodiments, the support member 123 may also be directly formed on other inner sidewalls 22 of the base 12 or on the top cover 11.

[0053] Please refer to it again Figure 7 and Figure 8 In some embodiments, the base 12 is concave facing the top cover 11, that is, the covering portion 121 is concave, and the end of the top cover 11 is adapted to be inserted into the base 12; the base 12 is also provided with a protrusion 124, which forms a limiting groove 1241. The inner wall of the top cover 11 is provided with a limiting rib 114, which extends along the insertion direction of the top cover 11 and the base 12, and the limiting rib 114 is inserted into the limiting groove 1241. Taking the up-down direction as an example, the limiting rib 114 and the limiting groove 1241 extend along the up-down direction. When installing, the top cover 11 is inserted from top to bottom into the concave of the base 12. At this time, the limiting rib 114 moves along the limiting groove 1241, guiding and preventing the top cover 11 from rotating relative to the base 12. When the top cover 11 and the base 12 are installed in place, the lower end of the top cover 11 is accommodated in the base 12, the outer peripheral wall of the top cover 11 contacts the inner peripheral wall of the base 12, and the limiting protrusion on the inner side of the top cover 11 engages with the limiting groove 1241 on the base 12, so that both the inner and outer sides of the top cover 11 are limited. In addition, the provision of the protrusion 124 on the base 12 also strengthens the structure of the base 12.

[0054] Furthermore, a receiving groove 1222 is further provided on the side of the fixing protrusion 122 facing the mounting hole 111, and a communicating hole 1223 passes through the bottom of the receiving groove 1222. A sealing gasket 60 (such as Figure 6 As shown), the sealing gasket 60 has a through hole, the top cover 11 includes a conduit, a liquid channel 113 is formed inside the conduit, the lower end of the conduit abuts against the sealing gasket 60, and the through hole connects the liquid channel 113 with the communicating hole 1223.

[0055] Please refer to it again Figure 6 In some embodiments, the conductive connector 40 is plate-shaped and disposed facing the mounting hole 111. The plate-shaped conductive connector 40 provides a larger support area for the elastic conductor 30, thereby providing a more stable support effect and conductive connection. In this embodiment, the conductive connector 40 is disposed substantially perpendicular to the circuit board 50.

[0056] In some embodiments, the elastic conductor 30 is a spring. Of course, the elastic conductor 30 can also be a metal strip, and the two ends of the metal strip can be bent to form elastic arms.

[0057] Please refer to it again Figure 1 Furthermore, the physiotherapy device also includes a cover 70, which covers the upper end of the shell 10 to cover the electrode 20 and the liquid outlet end of the liquid channel 113 inside.

[0058] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
