Description

Technical Field

[0001] This application relates to the field of beauty and skincare technology, specifically to a physiotherapy device. Background Technology

[0002] Microneedling is a popular treatment in the beauty industry. Its principle involves using microneedles to create tiny punctures or perforations in the skin, causing minor physical damage. This triggers the skin's soft tissue repair mechanisms, activating its functions and promoting regeneration and repair. It also activates tissue cell metabolism and microcirculation. Microneedling is often used in conjunction with skincare products to enhance the penetration of active ingredients, promoting better absorption of nutrients and allowing for deeper, more effective skincare. When using a microneedling device, a microneedle patch with multiple microneedles is typically attached to the device's treatment unit. The device is then brought into contact with the skin to create these minor physical damages.

[0003] In related technologies, to reduce the risk of collision damage to the therapeutic components, they are typically housed in a recess when the device is not in use. However, the narrow space of the recess makes it difficult for users to precisely attach microneedle patches to specific locations on the therapeutic components using their fingers or tools, resulting in inconvenience and requiring further improvement.

[0042] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. In addition, it should be understood that the specific embodiments described herein are only for illustration and explanation of this application and are not intended to limit this application. In this application, unless otherwise stated, directional terms such as "upper" and "lower" generally refer to the upper and lower positions of the device in actual use or operation, specifically the drawing directions in the accompanying drawings; while "inner" and "outer" refer to the outline of the device.

[0043] Please refer to Figure 1 and Figure 2The physiotherapy device 100 of this application includes a main unit 1, a physiotherapy component 2, and a support frame 3. The main unit 1 includes a housing 11 and a mounting base 12. The mounting base 12 is fixed to one end of the housing 11. The mounting base 12 can be fixed to one end of the housing 11 by bonding, welding, screw connection, or other connection methods. The physiotherapy component 2 is disposed on the mounting base 12. The physiotherapy component 2 can be fixedly connected to the mounting base 12, or the physiotherapy component 2 can be movably connected to the mounting base 12. No limitation is made here.

[0044] In this embodiment, the physiotherapy device 2 has a carrier portion 21 for mounting microneedles (not shown in the figure). The microneedles can be fixed on the carrier portion 21. In use, the microneedles on the carrier portion 21 can be brought into contact with human skin, allowing the microneedles on the microneedles to make micro-perforations or punctures in the skin tissue for microneedle therapy. The type of microneedles is not limited. For example, the microneedles can be sheet-like microneedle patches with an adhesive layer on one side and multiple microneedles on the other side. The microneedles can be attached to the surface of the carrier portion 21 by adhesive bonding. Alternatively, the microneedles can be a sleeve structure, with the microneedles sleeved on the outer surface of the carrier portion 21.

[0045] In this embodiment, the support frame 3 is detachably fixed to the mounting base 12. For example, the support frame 3 can be detachably fixed to the mounting base 12 by magnetic connection, snap-fit ​​connection, screw connection, etc., which is not limited here. When it is necessary to fix the microneedle to the carrier 21 or to remove the microneedle from the carrier 21, the support frame 3 can be removed from the mounting base 12 first, and both the carrier 21 and the mounting base 12 are exposed, so as to avoid the support frame 3 obstructing the hand or tools from approaching the carrier 21. In addition, the carrier 21 protrudes from the mounting base 12 in a direction away from the outer shell 11, so the user can operate directly from the side or top of the carrier 21 without having to go around the mounting base 12, making the installation, fixing or removal of the microneedle more flexible and convenient. In addition, when it is not necessary to install or remove the microneedle patch, the carrier 21 can be accommodated in the receiving cavity 332 formed by the support frame 3 and the mounting base 12. The receiving cavity 332 can protect the carrier 21 and reduce the risk of collision damage between the carrier 21 and external devices.

[0046] In this embodiment, the mounting base 12 serves as a barrier. After the support frame 3 is removed from the mounting base 12, both the bearing portion 21 and the side of the mounting base 12 facing away from the outer shell 11 are exposed, while the components located inside the outer shell 11 are shielded by the mounting base 12 and will not be exposed. Therefore, when replacing the physiotherapy component 2 or the microneedles on the physiotherapy component 2, the user is less likely to accidentally touch or damage the components inside the outer shell 11.

[0047] In one embodiment, reference Figures 1 to 4The support frame 3 has multiple skin-contact portions 31 on the side away from the mounting base 12, which are used to contact the skin. For example, the physiotherapy device 2 is fixedly connected to the mounting base 12. The skin has a certain elasticity. After the support frame 3 contacts the skin, part of the skin can deform and protrude into the receiving cavity 332 to contact the microneedle patch on the support portion 21. For another example, the physiotherapy device 2 can move up and down in the receiving cavity 332. After the support frame 3 contacts the skin, the physiotherapy device 2 can move back and forth in the direction closer to the skin and away from the skin, so that the microneedles on the physiotherapy device 2 repeatedly contact the skin. In this embodiment, the skin-contact portions 31 are close to the skin surface, which can form a stable support point and reduce the accidental displacement of the physiotherapy device 100 during treatment.

[0048] In this embodiment, during microneedling therapy, prolonged contact between the skin-applying part 31 and the skin may hinder the evaporation of sweat from the skin in the receiving cavity 332. A ventilation gap 32 is formed between two adjacent skin-applying parts 31, and the ventilation gap 32 communicates with the receiving cavity 332. The ventilation gap 32 allows air circulation, timely removal of moisture from the receiving cavity 332, reduces the risk of skin dampness, enhances skin breathability, and reduces stuffiness and discomfort.

[0049] In one embodiment, reference Figure 1 and Figure 4 The support frame 3 has a surrounding wall 33, which surrounds the outer periphery of the bearing portion 21. The surrounding wall 33 and the mounting base 12 form a receiving cavity 332. At the end of the surrounding wall 33 away from the mounting base 12, there are multiple spaced-apart skin-contact portions 31. Adjacent skin-contact portions 31 are connected by an arc-shaped guide wall 333, which is recessed towards the mounting base 12. In this embodiment, the arc-shaped guide wall 333 provides a smooth transition between adjacent skin-contact portions 31, reducing sharp edges and improving comfort when the skin-contact portion 31 contacts the skin. In addition, during microneedling therapy, the skin may exude fluids such as sweat, tissue fluid, or blood. The guide wall 333 is an arc-shaped wall that is concave towards the mounting base 12. The guide wall 333 can guide these fluids to flow naturally along the curved surface to the ventilation gap 32 between the skin-contact parts 31. These fluids can be discharged through the ventilation gap 32, reducing the accumulation of fluids on the skin and the surrounding wall 33, reducing the risk of skin dampness, reducing stuffiness and discomfort, and at the same time, ensuring the cleanliness of the surrounding wall 33 and the support part 21.

[0050] In this embodiment, multiple spaced-apart skin-adhesive portions 31 can be evenly distributed along the circumference of the enclosure 33, which can improve ventilation and drainage. The cross-sectional shape of the enclosure 33 can be circular, elliptical, rectangular, or irregular, and is not limited thereto.

[0051] In one embodiment, reference Figure 1The enclosure 33 is also provided with a vent 331 communicating with the receiving cavity 332. The vent 331 is located on the side of the enclosure 33 closer to the mounting base 12, and the vent 331 is spaced apart from the vent gap 32. The vent 331 can further increase the ventilation effect of the receiving cavity 332, enhance skin breathability, and reduce stuffiness and discomfort. In addition, when the enclosure 33 is in contact with the skin, the vent gap 32 is close to the skin. When the skin deforms, it is easy for the skin to squeeze into the vent gap 32 and block the vent gap 32, affecting the ventilation of the receiving cavity 332. However, the vent 331 is located on the side of the enclosure 33 closer to the mounting base 12, and the vent 331 is spaced apart from the vent gap 32. The distance between the vent 331 and the skin is greater, and the skin is less likely to squeeze into the vent 331, reducing the risk of the vent 331 being blocked by the skin.

[0052] In one embodiment, reference Figure 2 , Figure 3 and Figure 8 The support frame 3 includes an interconnected enclosure wall 33 and an extension wall 34. The enclosure wall 33 surrounds the outer periphery of the support portion 21, and the enclosure wall 33 and the mounting base 12 form a receiving cavity 332. The extension wall 34 is disposed on the outer periphery of the enclosure wall 33. The physiotherapy device 100 also includes two conductive electrodes 4, which are fixed to the extension wall 34. The isolation design between the enclosure wall 33 and the extension wall 34 can prevent conductive interference between the conductive electrodes 4 and the microneedle area. The enclosure wall 33 can also isolate the exudate during physiotherapy, reducing the contamination of the conductive electrodes 4 by the exudate. Each conductive electrode 4 protrudes from the enclosure wall 33 in a direction away from the mounting base 12, and the portion of the conductive electrode 4 protruding from the enclosure wall 33 constitutes the skin-contact portion 31. On the one hand, the conductive electrode 4 is not only used for electrical stimulation physiotherapy, but also directly contacts the skin as the skin-contact portion 31, eliminating the need for an additional skin-contact structure, making the physiotherapy device 100 more compact and lightweight. On the other hand, electrical stimulation can be applied simultaneously with microneedle puncture, forming a synergistic composite therapy.

[0053] In this embodiment, the conductive electrode 4 serves as the skin-attached part 31. The surface of the conductive electrode 4 can be designed as an arc or a smooth transition to reduce local pressure on the skin. At the same time, the conductive electrode 4 can be made of conductive materials such as medical stainless steel or gold plating to improve biocompatibility.

[0054] In this embodiment, the enclosure wall 33 and the extension wall 34 can be integrally formed; or, the enclosure wall 33 and the extension wall 34 can be fixedly connected by means of adhesive, snap-fit ​​connection or other methods, which are not limited here.

[0055] In one embodiment, reference Figure 5 and Figure 6The support frame 3 is provided with a first limiting part 35, and the mounting base 12 is provided with a second limiting part 121 that matches the first limiting part 35. One of the first limiting parts 35 is a slot, and the other is a plug, with the plug and slot providing a limiting connection. On the one hand, the cooperation between the plug and the slot ensures that the support frame 3 and the mounting base 12 can be quickly aligned during assembly, reducing errors caused by manual adjustment. At the same time, it can reduce the rotation or offset of the support frame 3, ensuring that the relative positions of the physiotherapy component 2, conductive electrode 4, and other parts are fixed, thus ensuring the consistency and precision of the physiotherapy effect. On the other hand, users can quickly disassemble and install the support frame 3 through a "plugging and unplugging" action without tools (such as screwdrivers), improving ease of use.

[0056] In one specific embodiment, the first limiting part 35 is a slot located on the side of the support frame 3 facing the mounting base 12, and the second limiting part 121 is a plug adapted to the slot, located on the side of the mounting base 12 facing the support frame 3, and the plug can be inserted into the slot. In another specific embodiment, refer to... Figure 5 and Figure 6 The first limiting part 35 is an insert block located on the side of the support frame 3 facing the mounting base 12. The second limiting part 121 is a slot adapted to the insert block located on the side of the mounting base 12 facing the support frame 3. The insert block can be inserted into the slot.

[0057] In one embodiment, reference Figure 3 and Figure 8 The main unit 1 also includes a main circuit board 13. Two conductive elements 5 are provided on the side of the mounting base 12 facing the extension wall 34. The conductive elements 5 can be conductive springs or spring pins. Each conductive element 5 abuts against a corresponding conductive electrode 4, and each conductive electrode 4 is electrically connected to the main circuit board 13 through the corresponding conductive element 5. In this embodiment, the two conductive elements 5 directly and physically contact the corresponding conductive electrode 4, eliminating the need for complex wire soldering or terminal plugging, thus simplifying the circuit layout. Furthermore, when the support frame 3 containing the conductive electrode 4 is connected to the mounting base 12 via slots and plug-in blocks, the conductive electrode 4 automatically contacts and conducts with the conductive element 5, eliminating the need for additional wire insertion and removal, facilitating quick disassembly and installation of the support frame 3 by the user.

[0058] In this embodiment, the two conductive electrodes 4 include a first conductive electrode and a second conductive electrode, and the two conductive components 5 include a first conductive component and a second conductive component. During operation, the first conductive electrode, the first conductive component, the main circuit board, the second conductive component, and the second conductive electrode can be connected to form a microcurrent circuit. The microcurrent circuit is configured to form a microcurrent loop when the first conductive electrode and the second conductive electrode come into contact with the skin.

[0059] In one embodiment, reference Figure 5 and Figure 6The physiotherapy device 100 also includes a first magnetic element 122 and a second magnetic element 36 that attract each other. The first magnetic element 122 is fixed to the mounting base 12, and the second magnetic element 36 is fixed to the support frame 3. The magnetic elements cause the support frame 3 to automatically attract and return to its position when it approaches the mounting base 12. The user can quickly and easily attach and fix the support frame 3 using the first magnetic element 122 and the second magnetic element 36 without precise alignment. The first magnetic element 122 can be a magnet, and the second magnetic element 36 can be an iron sheet that can be attracted to the magnet. Alternatively, both the first magnetic element 122 and the second magnetic element 36 can be mutually attracting magnets.

[0060] In one specific embodiment, the mounting base 12 has two slots on the side facing the support frame 3. Two first magnetic elements 122 and one conductive element 5 are fixed to the bottom wall of each slot, with the conductive element 5 protruding from the bottom wall of the slot. The support frame 3 has two opposing extended walls 34. Each extended wall 34 has an insertion block on the side facing the mounting base 12, and each extended wall 34 has a conductive electrode 4. The conductive electrode 4 extends along the thickness direction of the extended wall 34, with one end protruding from the extended wall 34 away from the mounting base 12, and the other end extending to and protruding from the insertion block. When the insertion block is inserted into the slot, the conductive electrode 4 abuts against the conductive element 5.

[0061] In one embodiment, reference Figure 4 The physiotherapy device 100 also includes a first light source 14. The support frame 3 is made of a light-transmitting material. The first light source 14 is disposed adjacent to the support frame 3, and the light emitted by the first light source 14 can be emitted through the support frame 3 to perform phototherapy on the skin. Specifically, the physiotherapy device 100 also includes a first circuit board 19, which is electrically connected to the first light source 14. The first circuit board 19 is fixed on the mounting base 12, and the first light source 14 is fixed on the first circuit board 19. The mounting base 12 has a mounting hole communicating with the support frame 3. The first light source 14 is located in the mounting hole, and the light emitted by the first light source 14 can be emitted through the mounting hole to the support frame 3 and then emitted through the support frame 3. In another embodiment, the mounting base 12 has a light-transmitting area, and the first light source 14 faces the light-transmitting area. The light emitted by the first light source 14 can be emitted through the light-transmitting area to the support frame 3 and then emitted through the support frame 3.

[0062] In this embodiment, the first light source 14 can be a white light, red light, blue light, violet light, or infrared light, etc., and can be set as needed. The number of first light sources 14 can be one or more. When there are multiple first light sources 14, the multiple first light sources 14 can emit the same light or emit different light.

[0063] In one embodiment, reference Figure 3 and Figure 5 The physiotherapy device 100 also includes a second light source 15. The support portion 21 is made of a light-transmitting material. The second light source 15 is disposed adjacent to the support portion 21, and the light emitted by the second light source 15 can be emitted through the support portion 21 to perform phototherapy on the skin. Specifically, the physiotherapy device 100 also includes a second circuit board 20, which is electrically connected to the second light source 15. The second circuit board 20 is fixed on the mounting base 12, and the second light source 15 is fixed on the second circuit board 20. The mounting base 12 has a mounting hole communicating with the support portion 21. The second light source 15 is located in the mounting hole, and the light emitted by the second light source 15 can be emitted through the mounting hole to the support portion 21 and then emitted through the support portion 21. In another embodiment, the mounting base 12 has a light-transmitting area disposed adjacent to the support portion 21. The second light source 15 faces the light-transmitting area, and the light emitted by the second light source 15 can be emitted through the light-transmitting area to the support portion 21 and then emitted through the support portion 21.

[0064] In this embodiment, the second light source 15 can be a white light, red light, blue light, violet light, or infrared light, etc., and can be set as needed. The number of second light sources 15 can be one or more. When there are multiple second light sources 15, the multiple second light sources 15 can emit the same light or emit different light.

[0065] In one embodiment, reference Figure 2 and Figure 3 The physiotherapy device 100 also includes a storage compartment 16, which is detachably connected to the outer shell 11. The storage compartment 16 is used to store microneedles. In this embodiment, the storage compartment 16 is detachably connected to the outer shell 11, which makes it convenient for the user to directly remove the microneedles from the physiotherapy device 100, avoiding the need for the user to search for the microneedles separately. It also allows the microneedles to be carried along with the physiotherapy device 100, improving ease of use.

[0066] In this embodiment, the method of detachable connection between the storage compartment 16 and the outer shell 11 is not limited. For example, the inner wall surface of one end of the outer shell 11 has an internal thread, and the outer wall surface of the storage compartment 16 has an external thread that mates with the internal thread, so the storage compartment 16 is threadedly connected to one end of the outer shell 11. Another example is that the inner wall surface of one end of the outer shell 11 has a snap-fit, and the outer wall surface of the storage compartment 16 has a slot that mates with the snap-fit, so the storage compartment 16 is snap-fit ​​connected to one end of the outer shell 11.

[0067] In one embodiment, reference Figure 3 and Figure 4The support frame 3, mounting base 12, and outer casing 11 are arranged sequentially along a first direction, which is parallel to the axis of the main unit 1. The main unit 1 also includes a drive assembly 17, which drives the carrier 21 to reciprocate along the first direction. The support frame 3 and mounting base 12 provide a certain amount of space for the movement of the carrier 21, allowing it to reciprocate within a certain range of motion. Compared to static microneedles, the microneedles on the carrier 21 in this embodiment can repeatedly puncture the skin at a certain speed and impact force. Dynamic puncture can quickly open skin microchannels and promote the penetration efficiency of drugs or cosmetic ingredients. In addition, the linear reciprocating motion of the microneedles along the axis of the main unit 1 ensures that the microneedles penetrate the skin perpendicularly, reducing uneven puncture depth or skin tearing caused by microneedle tilting.

[0068] In one embodiment, the drive assembly 17 may include a linear motor (not shown) and a connecting rod. The linear motor is fixed in the housing 11, and one end of the connecting rod is fixedly connected to the output shaft of the linear motor, while the other end passes through the mounting base 12 and is fixedly connected to the support portion 21 in the receiving cavity 332. The linear motor can drive the connecting rod and the support portion 21 to perform linear reciprocating motion.

[0069] In one embodiment, reference Figure 3 , Figure 7 and Figure 8 The main unit 1 also includes a mounting bracket 18, which is located within the housing 11 and is fixedly connected to the housing 11. A drive assembly 17 is located within the mounting bracket 18. The mounting bracket 18 isolates the drive assembly 17 from direct contact with the housing 11, thereby reducing the vibration amplitude transmitted to the housing 11 and the mounting base 12. The drive assembly 17 includes a motor 171, a cam 172, a transmission component 173, and an elastic component 174. The motor 171, cam 172, and transmission component 173 are sequentially connected along a first direction. The motor 171 is fixed to the mounting bracket 18. Connection; one end of cam 172 is fixedly connected to the output shaft of motor 171, and the other end has a rotating inclined surface 1721; transmission component 173 includes a fixedly connected pressing component 1731 and a connecting component 1732, the connecting component 1732 is connected to the physiotherapy component 2, the outer surface of the pressing component 1731 has a buffer layer 1733, the pressing component 1731 abuts against the rotating inclined surface 1721 under the action of the elastic component 174, the motor 171 can drive the rotating inclined surface 1721 to rotate around the axis of the output shaft, and when the rotating inclined surface 1721 rotates, it can lift the pressing component 1731 in the first direction.

[0070] Specifically, the mounting bracket 18 has a hollow accommodating cavity, which can be vertical. The motor 171, cam 172, and transmission component 173 are connected sequentially from bottom to top, and are located within the accommodating cavity of the mounting bracket 18. The motor 171 is fixedly connected to the inner wall of the accommodating cavity. The top of the mounting bracket 18 has an opening communicating with the accommodating cavity. The mounting base 12 has a groove 124, and the bottom wall of the groove 124 has a through hole 123 communicating with the opening of the mounting bracket 18. One end of the connecting member 1732 is fixedly connected to the pressing member 1731, and the other end passes through the opening and the through hole 123 and connects to the physiotherapy component. The rotating inclined plane 1721 has a high end and a low end, with the low end closer to the motor 171 than the high end. An elastic member 174 is sleeved on the outer periphery of the connecting member 1732, with one end abutting against the mounting bracket 18 and the other end abutting against the pressing member 1731. When the pressure member 1731 contacts the lower end of the rotating inclined plane 1721, the support part 21 is in the initial position, and the microneedle is not in contact with the skin. As the cam 172 rotates, the pressure member 1731 contacts the rising section of the stroke of the rotating inclined plane 1721 and is lifted to the highest position at the upper end of the rotating inclined plane 1721. The pressure member 1731 drives the connecting member 1732 and the physiotherapy member 2 to move upward synchronously so that the support part 21 reaches the target position, at which point the microneedle can contact the skin. As the cam 172 continues to rotate, the pressure member 1731 contacts the falling section of the stroke of the rotating inclined plane 1721 and moves downward to the lowest position under the action of the elastic member 174. At this point, the support part 21 returns to the initial position. In this way, the reciprocating motion of the support part 21 along the first direction is realized.

[0071] In this embodiment, when the cam 172 rotates at high speed, the periodic impact of the rotating inclined plane 1721 on the pressing member 1731 will generate high-frequency vibration and noise. The buffer layer 1733 on the pressing member 1731 can absorb part of the impact force through elastic deformation, reducing noise and vibration, and thus reducing the loosening or relative movement between the support frame 3 and the mounting base 12 caused by vibration. In particular, when the support frame 3 is provided with a conductive electrode 4 and the mounting base 12 is provided with a conductive element 5, reducing the loosening or relative movement between the support frame 3 and the mounting base 12 caused by vibration can ensure the stability of the electrical connection between the conductive electrode 4 and the conductive element 5.

[0072] In this embodiment, the buffer layer 1733 can be made of flexible silicone, rubber, or an elastic polymer coating. The buffer layer 1733 can be fixed to the outer surface of the pressing member 1731 by means of adhesive, spraying, or other methods; the buffer layer 1733 can also be a sleeve structure, with the buffer layer 1733 directly sleeved on the outer surface of the pressing member 1731.

[0073] In one embodiment, reference Figure 3 and Figure 5The mounting base 12 has a through hole 123 that connects the mounting bracket 18 and the receiving cavity 332. One end of the connector 1732 is fixedly connected to the top pressing member 1731, and the other end passes through the through hole 123 and is connected to the bearing part 21. Under the action of the motor 171, the cam 172 and the elastic member 174, the connector 1732 can drive the bearing part 21 to reciprocate along the first direction. When the bearing part 21 moves along the first direction, it always maintains a distance from the mounting base 12 and the support frame 3. The bearing part 21 will not collide with the mounting base 12 and the support frame 3 during the movement, which can further reduce the loosening or relative movement between the support frame 3 and the mounting base 12 caused by vibration.

[0074] In one embodiment, reference Figure 7 and Figure 8 The mounting bracket 18 has a receiving cavity, and the transmission component 173 is located in the receiving cavity. The inner wall of the receiving cavity is provided with a guide groove 181, and the outer wall of the transmission component 173 is provided with a guide protrusion 1734 that is adapted to the guide groove 181. The guide protrusion 1734 can be movably set in the guide groove 181, which can improve the stability of the movement of the transmission component 173.

[0075] In one embodiment, reference Figure 5 and Figure 6 The physiotherapy component 2 includes a support portion 21 and a second insertion portion 22 connected to each other. A groove 124 is provided on the mounting base 12, and the support portion 21 is located within the groove 124, protruding outwards from the side wall of the groove 124. The surrounding wall 33 of the support frame 3 is fixed to the side wall of the groove 124, and the surrounding wall 33 and the groove 124 together form a receiving cavity 332. A through hole 123 is provided on the bottom wall of the groove 124. The second insertion portion 22 of the physiotherapy component 2 passes through the through hole 123 and is detachably connected to the connector 1732. The second insertion portion 22 can be detachably connected to the connector 1732 through plug-in connection, snap-on connection, magnetic connection, or other connection methods. When the user needs to replace or clean the physiotherapy component 2, the physiotherapy component 2 can be disassembled. In addition, the support part 21 protrudes from the mounting base 12 in a direction away from the outer shell 11. Users can directly pinch the protruding part of the support part 21 to apply force to remove the physiotherapy piece 2, making the installation, fixation or removal of the physiotherapy piece 2 more convenient.

[0076] In one embodiment, reference Figure 3 and Figure 5The mounting base 12 has a groove 124. The bearing part 21 protrudes from the groove 124 away from the outer shell 11. The bottom wall of the groove 124 has a through hole 123 that connects to the mounting bracket 18. One end of the connector 1732 is fixedly connected to the top pressing part 1731, and the other end protrudes from the bottom wall of the groove 124 after passing through the through hole 123. The end of the connector 1732 that protrudes from the bottom wall has a first insertion part 1735, so that the user can directly see and touch the first insertion part 1735 when changing the physiotherapy part 2, without having to search inside the groove 124, making the insertion and removal operation more convenient. The physiotherapy component 2 also includes a second insertion part 22, which is fixedly connected to the support part 21. One of the first insertion part 1735 and the second insertion part 22 is an insertion block, and the other is an insertion hole. For example, the first insertion part 1735 is an insertion hole provided on the connector 1732, and the second insertion part 22 is an insertion post that is interference-fitted with the insertion hole, with the insertion post inserted into the insertion hole. Alternatively, the first insertion part 1735 is an insertion post provided on the connector 1732, and the second insertion part 22 is an insertion hole that is interference-fitted with the insertion post, with the insertion post inserted into the insertion hole. The first insertion part and the second insertion part 22 are pluggable connected. The fit between the insertion block and the insertion hole can be an interference fit or a spring-loaded snap-fit, allowing the insertion block to be firmly fixed in the insertion hole.
