[0043] The following describes the specific implementation of this application in detail with specific embodiments:

[0044] Please refer to Figure 1 、 Figure 2 、 Figure 3 In some embodiments of this application, a physiotherapy device is provided. The physiotherapy device includes a housing 10, a light-transmitting member 20, a light-emitting device 30, and a sealing member 40. The housing 10 is provided with a receiving cavity 11 and an installation opening 12 communicating with the receiving cavity 11. The light-transmitting member 20 is located in the receiving cavity 11 and is disposed close to the installation opening 12. The light-emitting device 30 is disposed in the receiving cavity 11 and is used for emitting light toward the light-transmitting member 20. The sealing member 40 includes a first sealing portion 41 disposed around the installation opening 12, and the first sealing portion 41 seals the gap between the light-transmitting member 20 and the housing 10.

[0045] It should be noted that the housing 10 is the housing component of the physiotherapy device. The housing 10 is provided with a receiving cavity 11 and an installation opening 12. The receiving cavity 11 can be used to accommodate components (such as the light-transmitting member 20 and the light-emitting device 30, etc.), and the installation opening 12 communicates the receiving cavity 11 to the outside of the housing 10. The housing 10 can encapsulate and protect the components disposed therein. The shape and size of the housing 10 can be set as required.

[0046] The light-transmitting member 20 is made of a light-transmitting material and has light-transmitting properties. The light-transmitting member 20 is disposed in the receiving cavity 11 and is disposed close to the installation opening 12. The light-emitting device 30 is disposed in the receiving cavity 11, especially on the inner side of the light-transmitting member 20, that is, on the side of the light-transmitting member 20 facing away from the installation opening 12. The light-emitting device 30 is disposed adjacent to the light-transmitting member 20, and the light-emitting side of the light-emitting device 30 faces the light-transmitting member 20. The light-emitting device 30 can emit light toward the light-transmitting member 20, and the light emitted by the light-emitting device 30 can pass through the light-transmitting member 20 and be emitted to the outside through the installation opening 12. Among them, the light emitted by the light-emitting device 30 can be some light rays with physiotherapy effects and phototherapy effects, such as infrared rays, blue light, near-infrared, etc.

[0047] The seal 40 includes a first sealing portion 41 which is arranged in a ring shape and surrounds the inside of the mounting opening 12. The first sealing portion 41 seals the gap between the light transmissive member 20 and the housing 10, that is, the first sealing portion 41 can be sealed between the outer periphery of the light transmissive member 20 and the housing 10. Among them, the seal 40 can be made of an elastic material to enable the seal 40 to have better sealing performance.

[0048] In summary, the physiotherapy device provided by the embodiment of the present application can set the light transmissive member 20 in the area of the accommodation cavity 11 close to the mounting opening 12, and set the light emitting device 30 inside the light transmissive member 20, so that the light emitted by the light emitting device 30 can pass through the light transmissive member 20 and be emitted to the outside through the mounting opening 12, so that the physiotherapy device at least has a light therapy effect (that is, it can irradiate the human skin with light of a specific wavelength and intensity to produce a photobiological effect, so as to achieve light therapy effects such as treating diseases, promoting wound healing, and improving skin conditions).

[0049] On this basis, the first sealing portion 41 can also be arranged in a ring around the mounting opening 12 to seal the gap between the light transmissive member 20 and the housing 10 through the first sealing portion 41. Based on this, it is possible to prevent external liquids, dust, etc. from entering the accommodation cavity 11 along the gap between the light transmissive member 20 and the housing 10. Thus, by combining the functions of the housing 10, the seal 40 and the light transmissive member 20, the protection effect on the components (especially electrical components such as the light emitting device 30) in the accommodation cavity 11 can be improved, and thus the risk of damage to the components (especially electrical components such as the light emitting device 30) in the accommodation cavity 11 due to water ingress and impurity ingress can be reduced, and the service reliability and service life of the components (especially electrical components such as the light emitting device 30) in the accommodation cavity 11 can be improved.

[0050] Please refer to Figure 2 、 Figure 3 , in some embodiments of the present application, the housing 10 is provided with a limiting member 13 around the mounting opening 12, and the limiting member 13 is located outside the accommodation cavity 11. The physiotherapy device further includes a ball 50 which is installed in the space formed by the enclosure of the limiting member 13, the first sealing portion 41 and the light transmissive member 20, and part of the ball 50 protrudes outwards from the limiting member 13. The limiting member 13 restricts the ball 50 from disengaging from the mounting opening 12 outwards.

[0051] It should be noted that the housing 10 is provided with a limiting member 13 which is arranged in a ring shape. The limiting member 13 can be detachably connected to the mounting opening 12 so that the limiting member 13 surrounds the inside of the mounting opening 12. At least part of the limiting member 13 is located outside the accommodation cavity 11. Among them, the limiting member 13 and the mounting opening 12 can be detachably connected or fixedly connected. As Figure 3 shown, in some embodiments, the limiting member 13 and the mounting opening 12 can be buckled to each other via a convex ring and an annular groove.

[0052] The ball 50 is spherical and made of a light-transmitting material. A part of the ball 50 can be accommodated in the space formed by enclosing the limiting member 13, the first sealing portion 41, and the light-transmitting member 20, and another part of the ball 50 can protrude outward from the ring opening of the limiting member 13 and be exposed. The projected size of the ring opening of the limiting member 13 is smaller than the cross-sectional size of the (great circle passing through the center of the sphere) of the ball 50, so that the limiting member 13 can limit the ball 50 from disengaging from the ring opening of the limiting member 13, thereby restricting the ball 50 from separating outward from the mounting opening 12.

[0053] By adopting the above solution, the limiting member 13 arranged around the mounting opening 12 and located outside the accommodating cavity 11, in cooperation with the first sealing portion 41 and the light-transmitting member 20, can realize the rollably and reliably mounting of the ball 50 on the outer side of the light-transmitting member 20. Based on this, during the use of the physiotherapy device, the part of the ball 50 protruding outward from the limiting member 13 can roll and contact the human skin, and the light emitted by the light-emitting device 30 can pass through the light-transmitting member 20 and the ball 50 and irradiate the skin contacted by the ball 50, thereby optimizing the structure of the physiotherapy device and improving the performance of the physiotherapy device.

[0054] Please refer to Figure 2 、 Figure 3 In some embodiments of the present application, a circumferential limiting groove 21 is provided on the circumferential side of the light-transmitting member 20, a part of the first sealing portion 41 is embedded in the limiting groove 21, and the side of the first sealing portion 41 facing the mounting opening 12 also abuts against the limiting member 13.

[0055] By adopting the above solution, by embedding a part of the first sealing portion 41 into a circumferential limiting groove 21 on the outer circumference of the light-transmitting member 20, a circumferentially continuous sealing line can be formed between the first sealing portion 41 and the outer circumference of the light-transmitting member 20, thereby improving the sealing effect between the first sealing portion 41 and the outer circumference of the light-transmitting member 20, enabling the first sealing portion 41 to reliably seal the gap between it and the outer circumference of the light-transmitting member 20, and reliably preventing external liquids, dust, etc. from entering the accommodating cavity 11 along the gap between the outer circumference of the light-transmitting member 20 and the first sealing portion 41.

[0056] By adopting the above solution, by making the side of the first sealing portion 41 facing the mounting opening 12 abut against the limiting member 13, a reliable sealing line can be formed between the first sealing portion 41 and the limiting member 13, thereby improving the sealing effect between the first sealing portion 41 and the limiting member 13, enabling the first sealing portion 41 to reliably seal the gap between it and the limiting member 13, and reliably preventing external liquids, dust, etc. from entering the accommodating cavity 11 along the gap between the limiting member 13 and the first sealing portion 41.

[0057] Please refer to Figure 2 、 Figure 3, in some embodiments of the present application, one side of the light-transmitting member 20 facing the mounting opening 12 has a first concave arc surface 22, and an inner peripheral wall of the first sealing portion 41 is provided with a second concave arc surface 411. The balls 50 are respectively adapted to cooperate with the first concave arc surface 22 and the second concave arc surface 411.

[0058] By adopting the above scheme, the inner peripheral wall of the first sealing portion 41 can be locally adapted to cooperate with the balls 50 through the second concave arc surface 411, and one side of the light-transmitting member 20 facing the mounting opening 12 can be locally adapted to cooperate with the balls 50 through the first concave arc surface 22. Based on this, on the one hand, the balls 50 can be guided to smoothly roll and not move around in the hemispherical space formed by the first concave arc surface 22 and the second concave arc surface 411, so as to improve the installation position stability and rolling flexibility of the balls 50. On the other hand, the hemispherical space formed by the first concave arc surface 22 and the second concave arc surface 411 can accommodate a part of the balls 50 to compress the size of the physiotherapy device in the opening direction of the mounting opening 12, which is beneficial to the miniaturization of the physiotherapy device.

[0059] Please refer to Figure 2 , Figure 3 , Figure 4 , in some embodiments of the present application, the first sealing portion 41 includes a first skirt 412, a second skirt 413 and a connecting wall 414 which are respectively annular. The second skirt 413 is spaced inside the first skirt 412. Two sides of the connecting wall 414 are respectively connected to the first skirt 412 and the second skirt 413. The first skirt 412 is in sealing contact with the inner wall surface of the housing 10. A part of the second skirt 413 is embedded in the limiting groove 21, and the connecting wall 414 is in sealing contact with the limiting member 13.

[0060] It should be noted that the first skirt 412 is annular, the second skirt 413 is annular and is spaced inside the ring of the first skirt 412, and the connecting wall 414 is annular and is connected to one side of the first skirt 412 and the second skirt 413 close to the limiting member 13. In some embodiments, the connecting wall 414 and the first skirt 412, and the connecting wall 414 and the second skirt 413 can be integrally connected, that is, the first sealing portion 41 is an integrally formed structure. Of course, in other embodiments, it is allowed to adopt a split connection between the connecting wall 414 and the first skirt 412, and between the connecting wall 414 and the second skirt 413.

[0061] By adopting the above solution, the first sealing portion 41 can be in sealing abutment with the inner wall surface of the housing 10 through the annular first skirt 412 to seal the gap between the first sealing portion 41 and the inner wall of the housing 10. The first sealing portion 41 can also be embedded in a circumferential limiting groove 21 on the outer periphery of the light transmissive member 20 through the second skirt 413 which is annular and arranged at intervals within the ring of the first skirt 412 to seal the gap between the first sealing portion 41 and the outer periphery of the light transmissive member 20. The first sealing portion 41 can further be in sealing abutment with the limiting member 13 through the connecting wall 414 connecting the first skirt 412 and the second skirt 413 on the side close to the limiting member 13 to seal the gap between the first sealing portion 41 and the limiting member 13. Based on this, the first sealing portion 41 can form three sealing lines of defense between the outer periphery of the light transmissive member 20 and the housing 10, and can layer by layer seal the gap between the light transmissive member 20 and the housing 10, thereby improving the sealing effect of the first sealing portion 41 between the light transmissive member 20 and the housing 10, and reliably preventing external liquids, dust, etc. from entering the accommodation cavity 11 along the gap between the light transmissive member 20 and the housing 10.

[0062] As Figure 4 shown, in some embodiments, the first sealing portion 41 includes at least one reinforcing rib 415. The reinforcing rib 415 is arranged in the space formed by enclosing the first skirt 412, the second skirt 413 and the connecting wall 414, and the reinforcing rib 415 is respectively connected to the first skirt 412, the second skirt 413 and the connecting wall 414. With such an arrangement, the structural strength and connection strength of the first skirt 412, the second skirt 413 and the connecting wall 414 can be strengthened via the reinforcing rib 415, and the first skirt 412, the second skirt 413 and the connecting wall 414 can be made to reliably and tightly seal and abut against other components.

[0063] Please refer to Figure 2 , Figure 3 , Figure 5 , in some embodiments of the present application, the housing 10 is provided with a fixing port 14 communicating the accommodation cavity 11 with the outside, and a key assembly 60 is provided in the fixing port 14. The sealing member 40 further includes a second sealing portion 42 integrally formed with the first sealing portion 41. The second sealing portion 42 is located within the accommodation cavity 11 and seals the gap between the key assembly 60 and the fixing port 14.

[0064] It should be noted that the housing 10 is provided with a fixing port 14 which communicates the accommodation cavity 11 to the outside of the housing 10, and the fixing port 14 is used for installing the key assembly 60. The key assembly 60 is used for a user to press to trigger some functions of the physiotherapy device (such as turning on the light emitting device 30, turning off the light emitting device 30, adjusting the light intensity of the light emitting device 30, etc.).

[0065] In this case, the seal 40 is provided with a second sealing portion 42, and the second sealing portion 42 is integrally formed and integrally connected with the first sealing portion 41. The second sealing portion 42 is located within the accommodation cavity 11 and is correspondingly arranged with the fixing port 14. The second sealing portion 42 can seal the gap between the key assembly 60 and the fixing port 14 on the inner side of the fixing port 14.

[0066] By adopting the above solution, in the case where the housing 10 is provided with the fixing port 14 for installing the key assembly 60, the seal 40 can be provided with the second sealing portion 42 within the accommodation cavity 11, especially on the inner side of the fixing port 14, so as to seal the gap between the key assembly 60 and the fixing port 14 via the second sealing portion 42. Based on this, the sealing effect of the seal 40 can be optimized, and it can reliably prevent external liquids, dust, etc. from entering the accommodation cavity 11 along the gap between the key assembly 60 and the fixing port 14, thereby improving the protection effect on the components within the accommodation cavity 11, reducing the risk of damage to the components within the accommodation cavity 11 due to water ingress and impurity ingress, and improving the use reliability and service life of the components within the accommodation cavity 11.

[0067] Moreover, the design of integrally forming and integrally connecting the second sealing portion 42 and the first sealing portion 41 can improve the connection reliability, relative position stability, and relative state stability between the second sealing portion 42 and the first sealing portion 41, thereby enabling the second sealing portion 42 and the first sealing portion 41 to jointly exert the sealing effect in a stable relative position and relative state, thus improving the overall sealing effect of the seal 40. Also, the design of integrally forming and integrally connecting the second sealing portion 42 and the first sealing portion 41 is also convenient for the overall forming of the seal 40, improving the processing convenience of the seal 40; it can also reduce the number of components in the physiotherapy device, improving the assembly convenience and assembly efficiency of the physiotherapy device.

[0068] As Figure 3 、 Figure 5 shown, in some embodiments, along the through direction of the fixing port 14, the projected area of the second sealing portion 42 is larger than the projected area of the fixing port 14, such that the second sealing portion 42 can completely cover the inner side of the fixing port 14. The portion of the second sealing portion 42 that extends beyond the fixing port 14 can be sealingly attached to the inner wall of the housing 10. With such a setting, the sealing effect of the second sealing portion 42 on the gap between the key assembly 60 and the fixing port 14 can be optimized.

[0069] Of course, in other embodiments, the second sealing portion 42 and the first sealing portion 41 can be two separately formed components. After being separately formed, the second sealing portion 42 and the first sealing portion 41 can be separately connected to each other or can be separately and independently arranged.

[0070] Please refer to Figure 2 、 Figure 3 、 Figure 5, in some embodiments of the present application, the button assembly 60 includes a button base 61, and a trigger portion 62 and a conductive post 63 mounted on the button base 61. On one side of the second sealing portion 42 facing the fixing port 14, a first groove 421 is provided, and the button base 61 is fitted into the first groove 421. The second sealing portion 42 further has a first through hole 422 and a second through hole 423 penetrating the bottom of the first groove 421. The trigger portion 62 is hermetically inserted through the first through hole 422, and the conductive post 63 is hermetically inserted through the second through hole 423.

[0071] It should be noted that the button base 61 is the mounting base of the button assembly 60 and can be used to mount the trigger portion 62 and the conductive post 63. Correspondingly, on one side of the second sealing portion 42 facing the fixing port 14, a first groove 421 is provided, and a part of the button base 61 is embedded in the first groove 421.

[0072] The trigger portion 62 is used to press and trigger the corresponding function. The number of trigger portions 62 provided can be set as required. For example, Figure 5 as shown, in some embodiments, two trigger portions 62 are provided. Correspondingly, the bottom of the first groove 421 is provided with a first through hole 422 in a penetrating manner. The number and position of the first through holes 422 correspond to the number and position of the trigger portions 62. The trigger portions 62 are inserted through the first through holes 422 one by one, and the outer wall of the trigger portion 62 is hermetically attached to the hole wall of the first through hole 422.

[0073] The conductive post 63 is used to press and trigger the conduction of the circuit (i.e., switch triggering). The number of conductive posts 63 provided can be set as required. For example, Figure 5 as shown, in some embodiments, one conductive post 63 is provided. Correspondingly, the bottom of the first groove 421 is provided with a second through hole 423 in a penetrating manner. The number and position of the second through holes 423 correspond to the number and position of the conductive posts 63. The conductive posts 63 are inserted through the second through holes 423 one by one, and the outer wall of the conductive post 63 is hermetically attached to the hole wall of the second through hole 423.

[0074] In the case where the button assembly 60 includes a button base 61, a trigger portion 62, and a conductive post 63, by adopting the above solution, it is convenient for the second sealing portion 42 to accommodate, install, limit, and position the button base 61 via the first groove 421 and the fixing port 14, so that the structure of the second sealing portion 42 can be optimized, and the installation stability and reliability of the button assembly 60 can be improved. The second sealing portion 42 can also allow the trigger portion 62 to be hermetically inserted therethrough via the first through hole 422, so as to reliably seal the gap between the outer wall of the trigger portion 62 and the hole wall of the first through hole 422 on the basis of maintaining the triggering function of the trigger portion 62, thereby reducing the risk of water and impurities entering through the gap between the outer wall of the trigger portion 62 and the hole wall of the first through hole 422; the second sealing portion 42 can also allow the conductive post 63 to be hermetically inserted therethrough via the second through hole 423, so as to reliably seal the gap between the outer wall of the conductive post 63 and the hole wall of the second through hole 423 on the basis of maintaining the switch triggering function of the conductive post 63, thereby reducing the risk of water and impurities entering through the gap between the outer wall of the conductive post 63 and the hole wall of the second through hole 423; thus, on the basis of maintaining the triggering function of the button assembly 60, the structure of the second sealing portion 42 can be optimized, and the sealing effect of the second sealing portion 42 can be improved.

[0075] Moreover, since the seal 40 and the second sealing portion 42 are made of an elastic material, and since the first groove 421 is a groove-shaped structure, the bottom of the first groove 421 has the characteristics of a relatively thin thickness and good elasticity. Based on this, by arranging the first through hole 422 and the second through hole 423 at the bottom of the first groove 421, the trigger portion 62 and the conductive post 63 can be inserted through the bottom of the first groove 421. Thus, during the process of pressing the trigger portion 62 (or the conductive post 63), the bottom of the first groove 421 can generate adaptive elastic deformation and accumulate elastic force; and during the process of releasing the pressing of the trigger portion 62 (or the conductive post 63), the bottom of the first groove 421 can provide elastic force to prompt the trigger portion 62 (or the conductive post 63) to quickly reset; thereby improving the service performance and reliability of the button assembly 60.

[0076] Please refer to Figure 2 、 Figure 3 、 Figure 5 In some embodiments of the present application, two second grooves 424 are provided on the side of the second sealing portion 42 facing away from the fixing port 14, and the two second grooves 424 are respectively arranged on opposite sides of the first groove 421 and extend along the edge of the first groove 421.

[0077] It should be noted that the two second grooves 424 are both provided on the side of the second sealing portion 42 facing away from the fixing port 14 and are respectively arranged on opposite sides of the first groove 421. The second grooves 424 extend along the corresponding edges of the first groove 421. The shape of the second grooves 424 can be set as required, such as Figure 5As shown, in some embodiments, the second groove 424 is conical.

[0078] By adopting the above solution, the second sealing portion 42 can be provided with two second grooves 424 on the side facing away from the fixing port 14, so as to correspondingly reduce the thickness of the second sealing portion 42. Based on this, the problem of glue shrinkage caused by too large wall thickness during the processing can be reduced, and the structural reliability and sealing reliability of the second sealing portion 42 can be improved. Moreover, based on the design that the two second grooves 424 are respectively arranged on opposite sides of the first groove 421, it is beneficial to improve the elastic performance of the bottom of the first groove 421. Based on this, during the process of releasing the pressing of the trigger portion 62 (or the conductive post 63), the bottom of the first groove 421 can be prompted to provide a large elastic force, so as to prompt the trigger portion 62 (or the conductive post 63) to reset quickly and smoothly, thereby improving the use performance and use reliability of the key assembly 60.

[0079] Please refer to Figure 2 、 Figure 3 、 Figure 5 In some embodiments of the present application, the key base 61 is provided with a first hook 611, and the bottom of the first groove 421 is provided with a bayonet 4211, and the first hook 611 is hermetically clamped in the bayonet 4211.

[0080] By adopting the above solution, the key base 61 of the key assembly 60 can be positioned and stably installed relative to the first groove 421 of the second sealing portion 42 by clamping its first hook 611 in the bayonet 4211. Based on this, the installation stability and installation reliability of the key assembly 60 relative to the second sealing portion 42 and the housing 10 can be improved. Moreover, the first hook 611 and the bayonet 4211 are hermetically clamped to reliably seal the gap between the outer wall of the first hook 611 and the inner wall of the bayonet 4211. Thus, on the basis of realizing the connection and fixation between the key base 61 and the first groove 421, the risk of water and impurities entering from the gap between the first hook 611 and the bayonet 4211 can be reduced, and the sealing effect of the second sealing portion 42 can be improved.

[0081] Of course, in other embodiments, the key base 61 can be positioned or fixed relative to the second sealing portion 42 and the housing 10 in other ways. For example, by adhesion, etc.

[0082] Please refer to Figure 2 、 Figure 3 、 Figure 4, in some embodiments of the present application, the housing 10 includes a first housing 15 and a second housing 16. The first housing 15 and the second housing 16 are separately provided and jointly form a receiving cavity 11. The seal 40 further includes a third sealing portion 43 integrally formed with the second sealing portion 42. The third sealing portion 43 is sleeved between the second housing 16 and the first housing 15 and seals the gap between the second housing 16 and the first housing 15.

[0083] By adopting the above solution, the housing 10 can be made to include the first housing 15 and the second housing 16 that are separately formed and separately connected, so as to facilitate assembling components such as the light-emitting device 30 into the receiving cavity 11 jointly formed by the first housing 15 and the second housing 16 before the assembly of the first housing 15 and the second housing 16 is completed. Thus, the assembly of the physiotherapy device can be facilitated, and the assembly convenience of the physiotherapy device can be improved. In this case, the seal 40 can sleeve the third sealing portion 43 between the second housing 16 and the first housing 15 to seal the gap between the second housing 16 and the first housing 15 via the third sealing portion 43, thereby preventing external liquids, dust, etc. from entering the receiving cavity 11 along the gap between the second housing 16 and the first housing 15. Thus, the protection effect on the electrical components in the receiving cavity 11 can be improved, the risk of damage to the electrical components in the housing 10 due to water ingress and impurity ingress can be reduced, and the overall use reliability and service life of the physiotherapy device can be improved.

[0084] Moreover, based on the design that the third sealing portion 43 and the second sealing portion 42 are integrally formed and integrally connected, the connection reliability, relative position stability, and relative state stability between the third sealing portion 43 and the second sealing portion 42 can be improved. Thus, it can be promoted that the third sealing portion 43 and the second sealing portion 42 can jointly exert the sealing effect in a stable relative position and relative state, thereby improving the overall sealing effect of the seal 40. And the design that the third sealing portion 43 and the second sealing portion 42 are integrally formed and integrally connected also facilitates the overall forming of the seal 40, improves the processing convenience of the seal 40; it can also reduce the number of components in the physiotherapy device and improve the assembly convenience and assembly efficiency of the physiotherapy device.

[0085] Of course, in other embodiments, the third sealing portion 43 and the second sealing portion 42 can be two separately formed components. After being separately formed, the third sealing portion 43 and the second sealing portion 42 can be separately connected to each other or can be separately and independently provided.

[0086] Please refer to Figure 2 、 Figure 3 、 Figure 4, in some embodiments of the present application, the first housing 15 is cylindrical with one end opening as the installation opening 12, and the other end opening is sleeved with a third sealing portion 43. The first housing 15 is provided with a fixing opening 14. The second sealing portion 42 extends along the axial direction of the first sealing portion 41 and is connected to one side of the first sealing portion 41 and the third sealing portion 43.

[0087] By adopting the above scheme, the layout of the first sealing portion 41, the second sealing portion 42 and the third sealing portion 43 of the seal 40 can be optimized, the structure of the seal 40 can be optimized, and the assembly and cooperation between the seal 40 and the first housing 15 can be facilitated. During the assembly process, the first sealing portion 41 of the seal 40 can be installed around the installation opening 12 of the first housing 15, and the third sealing portion 43 of the seal 40 can be sleeved on the opening of the first housing 15 away from the installation opening 12. At this time, the second sealing portion 42 integrally connected to the same side of the first sealing portion 41 and the third sealing portion 43 basically realizes "extending along the axial direction of the first sealing portion 41 and sealing the fixing opening 14 of the first housing 15". Thus, the assembly steps of the seal 40 and the first housing 15 can be simplified, and the assembly convenience and assembly efficiency of the seal 40 and the first housing 15 can be improved.

[0088] Please refer to Figure 2 、 Figure 3 、 Figure 6 、 Figure 7 , in some embodiments of the present application, the physiotherapy instrument further includes a fixing bracket 70 provided in the accommodation cavity 11. The light-transmitting member 20 is integrally formed with the fixing bracket 70. A first installation cavity 71 is formed by enclosing between the light-transmitting member 20 and the fixing bracket 70, and the light-emitting device 30 is installed in the first installation cavity 71.

[0089] It should be noted that the fixing bracket 70 can be fixed relative to the housing 10 by means of detachable connection or fixed connection. The light-transmitting member 20 is integrally formed and integrally connected to the side of the fixing bracket 70 close to the installation opening 12. The light-transmitting member 20 and the fixing bracket 70 can be integrally formed as a whole with a light-transmitting material. Of course, the light-transmitting member 20 can also be made of a light-transmitting material alone, and then the light-transmitting member 20 and the fixing bracket 70 made of different materials are integrally connected by means of injection molding or the like. In this case, the fixing bracket 70 is not limited to being made of a light-transmitting material.

[0090] There is a gap space between the light-transmitting member 20 and the fixing bracket 70, and this gap space forms the first installation cavity 71. One side of the first installation cavity 71 is provided with an opening. The opening of the first installation cavity 71 does not face the light-transmitting member 20 nor face away from the light-transmitting member 20, but is provided on other sides of the first installation cavity 71. The light-emitting device 30 can be installed into the first installation cavity 71 through the opening of the first installation cavity 71.

[0091] By adopting the above solution, by integrally connecting the light-transmitting member 20 to the side of the fixing bracket 70 close to the installation opening 12, the connection and fixation of the light-transmitting member 20 and the fixing bracket 70 can be conveniently and quickly achieved. Moreover, it is convenient to directly form the first installation cavity 71 via the gap space between the light-transmitting member 20 and the fixing bracket 70, so as to install and accommodate the light-emitting device 30 via the first installation cavity 71. Based on this, the light emitted by the light-emitting device 30 can directly pass through the light-transmitting member 20, and whether the fixing bracket 70 is made of a light-transmitting material or not will not affect the light transmission of the light-emitting device 30, thereby optimizing the layout among the light-transmitting member 20, the fixing bracket 70, and the light-emitting device 30.

[0092] Of course, in other embodiments, the light-transmitting member 20 can be fixedly connected or detachably connected to the side of the fixing bracket 70 close to the installation opening 12, and is not limited to integral connection.

[0093] Please refer to Figure 2 , Figure 3 , Figure 6 , Figure 7 , in some embodiments of the present application, the fixing bracket 70 is further provided with a second installation cavity 72 and a third installation cavity 73. The third installation cavity 73, the second installation cavity 72, and the first installation cavity 71 are sequentially distributed along the opening direction of the installation opening 12. A battery 80 is provided in the second installation cavity 72, and a vibrator 90 is provided in the third installation cavity 73.

[0094] It should be noted that the fixing bracket 70 is further provided with a second installation cavity 72 and a third installation cavity 73. The third installation cavity 73, the second installation cavity 72, and the first installation cavity 71 are sequentially distributed along the opening direction of the installation opening 12 and along the direction close to the installation opening 12. A battery 80 is provided in the second installation cavity 72. The battery 80 is electrically connected to other power-consuming components (such as the light-emitting device 30, the vibrator 90, etc.). The battery 80 can be a storage battery 80, and the battery 80 is used to provide the electrical energy stored therein for the power-consuming components. A vibrator 90 is provided in the third installation cavity 73. When the vibrator 90 is started, the whole physiotherapy device can be driven to vibrate via the fixing bracket 70 and the housing 10 fixedly connected to the fixing bracket 70. Among them, the vibrator 90 can be fixed to the fixing bracket 70 by a detachable connection method or a fixed connection method, such as by adhesion.

[0095] By adopting the above solution, the light-emitting device 30 can be installed via the first installation cavity 71 of the fixing bracket 70, the battery 80 can be installed via the second installation part of the fixing bracket 70, the vibrator 90 can be installed via the third installation cavity 73 of the fixing bracket 70, and the vibrator 90, the battery 80, and the light-emitting device 30 can be arranged in sequence in the direction close to the installation opening 12. Based on this, the layout of the vibrator 90, the battery 80, and the light-emitting device 30 on the fixing bracket 70 can be optimized, which is convenient for the vibrator 90 and the light-emitting device 30 to be electrically connected to the battery 80 respectively to facilitate the battery 80 to perform the power supply function, convenient for the light-emitting device 30 to be arranged close to the light-transmitting member 20 to facilitate the light-emitting device 30 to perform the light-emitting function, and convenient for the vibrator 90 to drive the whole physiotherapy device to vibrate via the fixing bracket 70 and the housing 10 fixedly opposite to the fixing bracket 70. Thus, it is convenient to modularly assemble the fixing bracket 70 and the components installed on the fixing bracket 70 first, and then assemble the modular component into the housing 10, thereby optimizing the structure of the physiotherapy device, enriching the functions and physiotherapy effects of the physiotherapy device, and improving the assembly convenience, assembly efficiency, and service performance of the physiotherapy device.

[0096] Please refer to Figure 2 、 Figure 3 、 Figure 6 、 Figure 7 In some embodiments of the present application, one side of the first installation cavity 71 is provided with an opening, and a second hook 74 is provided on the periphery of the opening of the first installation cavity 71, and the hook portion of the second hook 74 hooks the light-emitting device 30.

[0097] It should be noted that one side of the first installation cavity 71 is provided with an opening to facilitate the installation of the light-emitting device 30 into the first installation cavity 71 via the opening of the first installation cavity 71. At least one second hook 74 is provided on the periphery of the opening of the first installation cavity 71, and the hook portion of the second hook 74 can hook the side of the light-emitting device 30 facing it.

[0098] By adopting the above solution, the fixing bracket 70 can be provided with one or more second hooks 74 on the periphery of the opening of the first installation cavity 71, so as to hook the side of the light-emitting device 30 facing the second hook 74 via the hook portion of the second hook 74, thereby limiting the light-emitting device 30 between the second hook 74 and the first installation cavity 71, so as to realize the limit installation of the light-emitting device 30, improve the installation convenience, installation stability, and installation reliability of the light-emitting device 30. Moreover, it is also convenient for the subsequent disassembly, maintenance, and replacement of the light-emitting device 30.

[0099] Of course, in other embodiments, other methods can be used to fix the light-emitting device 30 in the first installation cavity 71, such as using adhesion, etc.

[0100] Please refer to Figure 2 、 Figure 3 、 Figure 6, Figure 7 , in some embodiments of the present application, one side of the second installation cavity 72 is open, and a main control board 100 is provided at the opening of the second installation cavity 72. The main control board 100, the light-emitting device 30, the battery 80, and the vibrator 90 are electrically connected. A third hook 75 is provided on the peripheral edge of the opening of the second installation cavity 72, and the hooked portion of the third hook 75 hooks the main control board 100.

[0101] It should be noted that one side of the second installation cavity 72 is open to facilitate the installation of the battery 80 into the second installation cavity 72 through the opening of the second installation cavity 72. In the case where the battery 80 is installed in the second installation cavity 72, the main control board 100 can be optimally arranged at the opening of the second installation cavity 72. Based on this, it is convenient to establish electrical connections between the main control board 100 and the light-emitting device 30, the battery 80, and the vibrator 90 respectively. There are integrated circuits on the main control board 100, and the main control board 100 can control the light-emitting device 30, the battery 80, and the vibrator 90. As Figure 2 shown, in some embodiments, the button assembly 60 is installed in the fixing port 14 and is arranged opposite to the main control board 100. The button assembly 60 is used to trigger the main control board 100 to implement corresponding functions.

[0102] By adopting the above solution, the physiotherapy device can set the main control board 100 in the accommodation cavity 11 to control the operation of components such as the light-emitting device 30, the battery 80, and the vibrator 90 through the main control board 100. Based on this, the structure of the physiotherapy device can be optimized, and the performance of the physiotherapy device can be improved. Moreover, in the case where the battery 80 is installed in the second installation cavity 72, this embodiment can optimally arrange the main control board 100 at the opening of the second installation cavity 72 to optimize the layout of the main control board 100, the fixing bracket 70, the light-emitting device 30, the battery 80, and the vibrator 90, so as to optimize and stabilize the installation position and installation state of the main control board 100, and facilitate the establishment of electrical connections between the main control board 100 and the light-emitting device 30, the battery 80, and the vibrator 90 respectively. Moreover, after installing the main control board 100, it is also convenient to relatively close the opening of the second installation cavity 72 through the main control board 100, and conveniently and quickly limit and fix the battery 80.

[0103] It should also be noted that at least one third hook 75 is provided on the peripheral edge of the opening of the second installation cavity 72. The number and position of the third hooks 75 can be set as required. As Figure 6 shown, in some embodiments, four third hooks 75 are provided. Each of the third hooks 75 jointly limits the main control board 100.

[0104] By adopting the above solution, the fixing bracket 70 can be in abutting cooperation with the main control board 100 through its side surface facing the main control board 100 to preliminarily stabilize the installation position and state of the main control board 100; then, through the rod parts of the third hooks 75 distributed on the periphery of the main control board 100, circumferential limitation of the main control board 100 is realized to strengthen and stabilize the installation position and state of the main control board 100; further, through the hook parts of the third hooks 75, abutting cooperation is carried out with the side surface of the main control board 100 facing the hook parts of the third hooks 75 to limit the main control board 100 from detaching from the fixing bracket 70. Thus, the all-round limitation and stabilization of the main control board 100 on the fixing bracket 70 can be conveniently, quickly and reliably realized, and the installation convenience and stability of the main control board 100 can be improved. Moreover, by using the third hooks 75 to limit and fix the main control board 100, most of the main control board 100 can be exposed, which is convenient for the connection and cooperation of the main control board 100 with components such as the light-emitting device 30, the battery 80, and the vibrator 90, and is also convenient for the heat dissipation of the main control board 100.

[0105] Of course, in other embodiments, the main control board 100 can be fixed to the fixing bracket 70 in other ways, such as by bonding.

[0106] Please refer to Figure 3 、 Figure 6 、 Figure 7 In some embodiments of the present application, the fixing bracket 70 is provided with a first rib 76.

Moreover, the setting of the second ribs 17 is also beneficial to improving the structural strength and structural reliability of the housing 10.

[0108] By adopting the above solution, after the fixed bracket 70 and the components installed on the fixed bracket 70 are assembled together to form a modular component, the fixed bracket 70 can be directly slidably connected to the chute 18 of the housing 10 along the opening direction of the installation opening 12 via the first rib 76, so as to be conveniently, quickly and rapidly positioned and installed in the housing 10. Based on this, the assembly convenience and assembly efficiency between the fixed bracket 70 and the housing 10 can be improved, and the installation accuracy and installation stability of the fixed bracket 70 in the housing 10 can be improved.

[0110] By adopting the above solution, during the sliding process of the first rib 76 in the chute 18, the buckle portion 762 of the first rib 76 can be buckled with the card slot 181 of the chute 18, so as to directly determine by feel that the first rib 76 slides in place relative to the chute 18 during the blind operation, and the first rib 76 can be urged to be buckled and fixed with the chute 18, thereby improving the assembly convenience, assembly efficiency and installation stability between the first rib 76 and the chute 18, and between the fixed bracket 70 and the housing 10.

[0111] Wherein, one first rib 76, two second ribs 17 and a chute 18 formed therebetween are a set of matching components. Between the fixed bracket 70 and the housing 10, one set or multiple sets of such matching components can be provided. For example, Figure 3 As shown, in some embodiments, two sets of such matching components are provided, and the two sets of matching components are respectively arranged on opposite sides of the fixed bracket 70. That is, there are two first ribs 76 and two chutes 18, and each chute 18 is formed by enclosing two parallel second ribs 17 (i.e., there are four second ribs 17 in total).

[0112] Wherein, in some embodiments, the stop portion 761 can be perpendicular to the main body portion of the first rib 76.

[0113] Of course, in other embodiments, other assembly methods can be adopted between the fixed bracket 70 and the housing 10, such as plugging, snap connection, etc.
