[0041] To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings. The described embodiments should not be regarded as limitations on this application. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0042] In the following description, references are made to “some embodiments,” which describe a subset of all possible embodiments. However, it is understood that “some embodiments” may be the same subset or different subsets of all possible embodiments and may be combined with each other without conflict.

[0043] In the following description, the terms "first, second, third" are used merely to distinguish similar objects and do not represent a specific ordering of objects. It is understood that "first, second, third" may be interchanged in a specific order or sequence where permitted, so that the embodiments of this application described herein can be implemented in an order other than that illustrated or described herein.

[0044] Unless otherwise defined, all technical and scientific terms used in the embodiments of this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the embodiments of this application is for the purpose of describing the embodiments of this application only and is not intended to limit this application.

[0045] Modern massage combs typically incorporate multiple functional modules to enhance their effectiveness, such as heating, vibration, or liquid-based massage designs.

[0046] Some massage combs combine with skincare liquids for massage; these combs have a liquid-dispensing module for pumping out the liquid. Currently, one of the technical challenges that needs to be addressed is how to increase the liquid distribution area while miniaturizing the liquid-dispensing module.

[0047] Therefore, this application provides a liquid guiding module. By setting multiple liquid channels in the liquid guiding component of the liquid guiding module, the portions of the multiple liquid channels near the liquid guiding inlet are concentrated and compactly arranged, while the portions near the liquid guiding outlet are radially dispersed, thereby increasing the distribution area of ​​the nursing liquid flowing out from the liquid guiding outlet. Furthermore, because the portions of the multiple liquid channels are concentrated and compactly arranged, the portions where the liquid channels are set can be set relatively small, which is beneficial for the miniaturization of the liquid guiding module.

[0048] The following, in conjunction with the appendix Figures 1 to 18 The embodiments of this application will be described in detail.

[0050] In some embodiments of this application, for ease of explanation, a first direction, a second direction, and a third direction are defined, and these three directions are perpendicular to each other. However, those skilled in the art should understand that the embodiments of this application are not limited to the case where these three directions are perpendicular to each other. For ease of explanation, as... Figures 2 to 10 , Figures 13 to 18 As shown by the arrows, the direction of arrow X is the first direction, the direction of arrow Y is the second direction, and the direction of arrow Z is the third direction. The direction that arrow X points in along the first direction is called "above", and its opposite direction is called "below".

[0051] The first aspect of this application provides a liquid guiding module, such as Figures 1 to 5As shown, the liquid guiding module includes a main unit 1 and a liquid guiding component 2. The main unit 1 includes a liquid supply module with a liquid outlet interface. The liquid guiding component 2 includes a connecting part 22 and a dispersing part 23. The connecting part 22 has a guiding hole extending along a first direction X. At least two partition walls 222 are provided inside the guiding hole. All partition walls 222 are distributed sequentially around the central axis of the guiding hole and are connected at the central axis of the guiding hole. Each partition wall 222 is connected to the hole wall of the guiding hole and divides the guiding hole into at least two first liquid flow channels 223. Each first liquid flow channel 223 is located at one end of the connecting part 22 along the first direction X. A liquid inlet 221 is formed, and one end of the connecting part 22 with the liquid inlet 221 is connected to the liquid outlet interface; the dispersing part 23 is connected to the other end of the connecting part 22 along the first direction X, and the dispersing part 23 has at least two second liquid channels 233 arranged sequentially around the central axis of the guiding hole. One end of each second liquid channel 233 is connected to at least one first liquid channel 223, and the other end forms a liquid outlet 2334 on the side of the dispersing part 23 away from the connecting part 22. The distance between the liquid outlet 2334 and the central axis of the guiding hole is greater than the distance between the first liquid channel 223 and the central axis of the guiding hole.

[0052] A flow-guiding hole refers to a channel provided in the connecting part 22 that extends along the first direction X, serving as the main path for liquid to enter the liquid guiding component 2. For example, the flow-guiding hole can be a hollow cylindrical structure with multiple partition walls 222 inside to achieve initial flow diversion. The partition walls 222 are partition structures disposed within the flow-guiding hole and sequentially distributed around its central axis. By dividing the flow-guiding hole into multiple independent first liquid flow channels 223, initial multi-path flow diversion is achieved, thus laying the foundation for subsequent balanced distribution. For example, the partition wall 222 can be a flat plate made of a rigid material, with two or more of these plate structures sequentially distributed around the central axis of the flow-guiding hole, dividing the flow-guiding hole into two or more independent first liquid flow channels 223. For example, there are six partition walls 222, which are evenly distributed sequentially around the central axis of the flow-guiding hole, dividing the flow-guiding hole into six uniformly sized first liquid flow channels 223.

[0053] Understandably, one end of all the partition walls 222 is connected at the central axis of the guide hole, and the other end is connected to the hole wall of the guide hole. Thus, along the circumference of the guide hole, the portion of the hole wall between two adjacent partition walls 222 defines the first liquid flow channel 223. For example, the guide hole is a circular hole, and the cross-section of the first liquid flow channel 223 is fan-shaped.

[0054] The liquid flow channel refers to the path of liquid flow within the liquid guide 2. Depending on its location, it can be divided into a first liquid flow channel 223 and a second liquid flow channel 233. The former is located at the connecting part 22 and is responsible for initial flow distribution; the latter is located at the dispersing part 23 and is responsible for uniformly guiding the liquid from the connecting part 22 to the liquid outlet 2334. The cross-section of the first liquid flow channel 223 can be, but is not limited to, fan-shaped, square, triangular, etc. The cross-section of the second liquid flow channel 233 can be, but is not limited to, circular, fan-shaped, square, triangular, elliptical, etc.

[0055] The liquid inlet 221 refers to the liquid input port formed at one end of the connecting part 22, which is usually connected to an external pumping system (such as the pump liquid module 13 of the massage comb) to receive the nursing liquid from the storage tank 120. For example, one end of the connecting part 22 with the liquid inlet 221 is directly connected to a liquid guide tube inside the main unit 1, so that the nursing liquid in the liquid guide tube can be divided into multiple flow paths under the action of the partition wall 222, and the multiple flow paths flow towards the second liquid flow path 233 through multiple first liquid flow channels 223 respectively.

[0056] The liquid outlet 2334 refers to the liquid outlet formed on the side of the dispersion section 23 away from the connecting section 22. Each liquid outlet 2334 is far from the central axis of the guide hole. This arrangement allows the liquid to be fully distributed in the dispersion section 23 and then flow out evenly to the target area. For example, the liquid outlet 2334 can be six radially distributed small holes, which correspond to the ends of the six second liquid channels 233, and are used to evenly apply the liquid to the user's massage area.

[0057] For example, the number of first liquid channels 223 and second liquid channels 233 are the same, and they are connected in a one-to-one correspondence. The first liquid channels 223 are evenly distributed around the central axis of the guide hole, and the second liquid channels 233 are evenly distributed around the central axis of the guide hole.

[0058] In the embodiments of this application, by providing multiple partition walls 222 within the guide orifice, the liquid can be divided into multiple independent flow paths after entering the liquid guide 2, thereby achieving initial diversion. Subsequently, the liquid in the first liquid flow channel 223 flows through the corresponding second liquid flow channel 233 connected to the first liquid flow channel 223 to the liquid guide outlet 2334. Since the liquid guide outlet 2334 is located away from the central axis of the guide orifice, the liquid flows out in a radial distribution, enhancing the liquid diffusion effect, increasing the liquid distribution area of ​​the liquid guide 2, and improving the uniformity and coverage of the liquid output. In addition, since each first liquid flow channel 223 is concentrated and compactly arranged in the connecting part 22, it is beneficial to reduce the size of the connecting part 22 in any direction perpendicular to the first direction X, thereby facilitating the miniaturization of the liquid guide 2. Therefore, the liquid guide 2 provided by the embodiments of this application not only facilitates the miniaturization of the liquid guide 2 but also increases the liquid distribution area.

[0059] In some embodiments, such as Figure 5 As shown, each second liquid flow channel 233 includes a first flow section 2331, a second flow section 2332, and a third flow section 2333. The first flow section 2331 extends along the first direction X and is connected to the first liquid flow channel 223. One end of the second flow section 2332 is connected to the end of the first flow section 2331 away from the first liquid flow channel 223, and the other end extends obliquely along the direction away from the central axis of the guide hole. The third flow section 2333 extends along the first direction X, and one end of it is connected to the end of the second flow section 2332 away from the first flow section 2331. The other end forms a liquid outlet 2334 on the side of the dispersion section 23 away from the connecting section 22.

[0060] like Figure 5 As shown in the figure, the dashed line is the boundary line between the first liquid flow channel 223 and the first flow section 2331. The first liquid flow channel 223 is formed in the connecting part 22, and the first flow section 2331 is formed in the dispersing part 23.

[0061] The first flow section 2331 extends along the first direction X and is directly connected to the first liquid flow channel 223, allowing liquid to flow smoothly from the first liquid flow channel 223 into the second liquid flow channel 233. The second flow section 2332 extends from the end of the first flow section 2331 and extends at a certain angle. The inclination direction of the second flow section 2332 deviates from the central axis of the guide hole, thereby reducing liquid backflow or blockage. The inclined setting of the second flow section 2332 helps guide the liquid to flow radially, while reducing eddies or stagnant areas in the flow channel. Furthermore, the inclined setting of the second flow section 2332 can also regulate the flow velocity to a certain extent, thereby improving the uniformity of fluid distribution. The third flow section 2333 continues to extend along the first direction X and finally forms a liquid outlet 2334 on the outside of the dispersion section 23. The liquid outlet 2334 is used to uniformly discharge the liquid that has passed through the first two flow sections to the target location, such as the scalp surface or other application areas. By appropriately setting the length and width of the third flow section 2333, the speed and pressure of liquid outflow can be controlled to meet the needs of different application scenarios.

[0062] In this embodiment, the second liquid flow channel 233 is divided into a first flow section 2331, a second flow section 2332, and a third flow section 2333. The first flow section 2331 is responsible for receiving the liquid input from the first liquid flow channel 223; the second flow section 2332 adjusts the flow direction and reduces the risk of backflow by tilting; finally, the third flow section 2333 is responsible for exporting the liquid to the outside. In this way, the uniformity of liquid distribution can be improved, and the use effect and user experience of the massage comb can be further enhanced.

[0063] In some embodiments, such as Figure 3 and Figure 5 As shown, the dispersion section 23 includes a first section 231 and a second section 232. The connecting section 22 and the second section 232 are respectively connected to opposite sides of the first section 231 along the first direction X. A first flow section 2331 is formed in the first section 231. The first section 231 and the second section 232 surround each other to form a second flow section 2332. A third flow section 2333 is formed in the second section 232. A liquid outlet 2334 is formed on the surface of the second section 232 away from the first section 231.

[0064] like Figure 5 As shown in the figure, the dashed line represents the interface between the connecting part 22 and the first part 231. See [reference needed]. Figure 3 and Figure 5 The first liquid flow channel 223 is formed in the connecting portion 22, and the first flow section 2331 is formed in the first portion 231, that is, Figure 5 The dashed line in the figure represents the interface between the first liquid flow channel 223 and the first flow section 2331.

[0065] It should be noted that the first part 231 and the second part 232 are combined to form the second flow section 2332, indicating that the first part 231 and the second part 232 are formed separately, and are assembled to form the second flow section 2332. For example, the connection methods of the first part 231 and the second part 232 include welding, fastener connection, bonding, etc.

[0066] Thus, by dividing the dispersion section 23 into two independent parts, which together form the second flow section 2332, it is easier to manufacture and shape the inclined second flow section 2332. Moreover, it is easier to precisely control the size of the second flow section 2332, improve the dimensional accuracy of the second flow section 2332, and improve the stability and uniformity of the liquid flow.

[0067] Of course, it is understood that the dispersion section 23 is not limited to being divided into two separate parts. In other embodiments, the dispersion section 23 can be a one-piece molded structure, that is, when the dispersion section 23 is integrally molded, the first flow section 2331, the second flow section 2332 and the third flow section 2333 are formed.

[0068] In some embodiments, such as Figure 3 As shown, the liquid guiding component 2 includes a liquid guiding shell 21, at least a portion of the connecting portion 22 and a first portion 231 are housed within the liquid guiding shell 21, and the liquid guiding shell 21 includes a liquid guiding shell bottom 211, which serves as a second portion 232.

[0069] The liquid-conducting housing 21 refers to the outer shell used to encapsulate and protect its internal components. The main function of the liquid-conducting housing 21 is to provide mechanical support and improve the structural stability of the internal components. The liquid-conducting housing 21 is usually made of plastic materials with a certain degree of hardness and corrosion resistance, such as ABS (acrylonitrile-butadiene-styrene copolymer) or PC (polycarbonate), so that it is not easily deformed due to pressure or temperature changes during use.

[0070] Thus, by installing the connecting part 22 and the first part 231 inside the liquid guiding shell 21, the overall integrity of the module is improved, external interference is reduced, and installation and maintenance are facilitated. Moreover, the bottom 211 of the liquid guiding shell serves not only as part of the structure of the liquid guiding shell 21, but also as the second part 232 forming the second flow section 2332 and the third flow section 2333, reducing the number of parts, improving assembly efficiency, and also saving space and facilitating the miniaturization of the liquid guiding component 2.

[0071] In some embodiments, such as Figure 3As shown, the liquid guiding shell 21 also includes a liquid guiding shell cover 212 that is opposite to the liquid guiding shell bottom 211 along the first direction X. The liquid guiding shell cover 212 has a connecting through hole 2121. One end of the connecting part 22 with a liquid guiding inlet 221 extends outward through the connecting through hole 2121 and connects to the liquid outlet interface. The liquid guiding component 2 also includes a first sealing component 24. Part of the first sealing component 24 is sealed between the connecting part 22 and the hole wall of the connecting through hole 2121, and the other part is sealed between the connecting part 22 and the inner wall of the liquid outlet interface.

[0072] The liquid guide cover 212 is a part of the liquid guide shell 21 and is positioned opposite to the liquid guide shell bottom 211 along the first direction X. A portion of the connecting part 22 and the first part 231 are located within the space between the liquid guide cover 212 and the liquid guide shell bottom 211. The function of the liquid guide cover 212 is to protect the internal components and provide an outlet (connection through hole 2121) for the connecting part 22 to pass through the liquid guide shell 21. The connection through hole 2121 is a channel opened on the liquid guide cover 212. The diameter and shape of the connection through hole 2121 are matched to the size of the connecting part 22, allowing the connecting part 22 to pass through smoothly while reducing the risk of liquid leakage. One end of the connecting part 22 with the liquid guide inlet 221 serves as a fluid input point for connecting to the liquid supply module of the main unit. By extending the end of the connecting part 22 with the liquid guide inlet 221 out of the liquid guide shell 21, it can be easily connected to the liquid outlet interface of the liquid supply module to realize the function of liquid introduction or export. For example, the liquid-conducting housing 21 also includes a liquid-conducting sidewall 213 connected between the liquid-conducting housing bottom 211 and the liquid-conducting housing cover 212. The liquid-conducting sidewall 213 has an annular structure and is arranged around the liquid-conducting housing bottom 211. The liquid-conducting housing bottom 211, the liquid-conducting housing cover 212 and the liquid-conducting sidewall 213 together form the inner cavity of the liquid-conducting housing 21.

[0073] The first seal 24 is a sealing element used to prevent liquid leakage. It is typically made of elastic materials (such as rubber, silicone, etc.) and has good compression resilience and corrosion resistance. The first seal 24 includes two parts: one part is embedded in the gap between the connecting part 22 and the connecting through hole 2121 to fix the connecting part 22 and seal the liquid guiding shell 21; the other part surrounds the protruding part of the connecting part 22 and seals the liquid outlet interface between the connecting part 22 and the liquid supply module.

[0074] In the embodiments of this application, the liquid-conducting shell 21 serves as a basic frame, accommodating part of the connecting portion 22 and the first portion 231, providing physical support and protection for these components. The arrangement of the liquid-conducting shell cover 212 and the connecting through hole 2121 enables the orderly extension of the connecting portion 22 and facilitates external connection. The first sealing member 24 serves a sealing function, reducing internal leakage of the liquid-conducting shell 21 and improving the reliable connection of the external liquid-conducting tube.

[0075] In some embodiments, such as Figure 6 As shown, at least two flow guiding grooves 2321 are formed on the surface of the first part 231 away from the connecting part 22 along the first direction X. The surface of the liquid guiding shell bottom 211 facing the first part 231 and the flow guiding grooves 2321 form a second flow section 2332. The liquid guiding member 2 also includes a second sealing member 25, which is sandwiched between the liquid guiding shell bottom 211 and the first part 231. The second sealing member 25 includes at least two sealing parts 251, which surround the outer periphery of the groove opening of the flow guiding groove 2321. At least one sealing part 251 is provided around the outer periphery of the groove opening of each flow guiding groove 2321.

[0076] The flow-guiding groove 2321 refers to a groove structure provided on the surface of the first part 231, which can be strip-shaped. The flow-guiding groove 2321 is provided to facilitate the formation of a second flow section 2332 with the liquid-guiding shell bottom 211. For example, the surface of the liquid-guiding shell bottom 211 facing the first part 231 is a plane, and the plane closes part of the groove opening of the flow-guiding groove 2321. The part of the flow-guiding groove 2321 that is not separated by the plane serves as the opening for the second flow section 2332 to connect to the third flow section 2333. For example, six radially distributed flow-guiding grooves 2321 are provided on the surface of the first part 231. The liquid-guiding shell bottom 211 and the six flow-guiding grooves 2321 are aligned to form six radially distributed second flow sections 2332. For example, the surface of the liquid-guiding shell bottom 211 facing the first part 231 is a conical surface that protrudes in the middle and extends obliquely around the edges. The flow-guiding grooves 2321 are also oblique grooves with the same oblique direction, thus forming an obliquely extending second flow section 2332.

[0077] The second seal 25 is a sealing component used to reduce liquid leakage and can be made of an elastic material, such as rubber or silicone. The second seal 25 is sandwiched between the bottom of the liquid guide shell 211 and the first part 231, acting as an isolation layer to prevent liquid flowing through the second flow section 2332 from leaking from the mating surface between the bottom of the liquid guide shell 211 and the first part 231. The position and shape of the second seal 25 should match the flow guide groove 2321 to achieve a good sealing effect. Each sealing part 251 refers to an independent sealing unit of the second seal 25 arranged around the edge of the groove opening of the flow guide groove 2321. For example, each sealing part 251 corresponds to one flow guide groove 2321 and surrounds the outer periphery of the flow guide groove 2321 to improve the sealing performance of each flow guide groove 2321. The number of sealing portions 251 can be configured according to the number of flow guide grooves 2321. For example, the second seal 25 includes six sealing portions 251, which are arranged one-to-one with the six flow guide grooves 2321, and the parts of the six sealing portions 251 that are close to each other are connected together to form an integral structure. For example, each sealing portion 251 is an elongated oval ring.

[0078] For example, the connecting part 22 and the first part 231 are integrally formed structures, and the connecting part 22 and the first part 231 form a liquid guiding bracket. The first sealing member 24 and the second sealing member 25 are formed onto the liquid guiding bracket by a two-color molding process, so as to realize the fixed connection of the first sealing member 24 and the second sealing member 25 on the liquid guiding bracket, which is beneficial to improve the sealing performance.

[0079] Thus, the design of the flow guide groove 2321 facilitates the increase of the flow area of ​​the second flow section 2332 and makes it easier to seal the two ends of the flow guide groove 2321 along its extension direction, thereby improving the sealing effect. Furthermore, the use of a second sealing element 25 containing multiple sealing parts 251 further enhances the sealing performance.

[0080] In some embodiments, such as Figure 3 As shown, the first part 231 and the connecting part 22 are integrated into a single structural component; the first part 231 and the second part 232 are separate components.

[0081] An integrated structural component refers to a structure in which the first part 231 and the connecting part 22 form an inseparable whole. This can be achieved by combining two originally detachable or separate components through injection molding, casting, or other integrated manufacturing processes to form an inseparable whole structure, or it can be a structure that was originally molded as a single piece. For example, the integrated structural component is made of a rigid material, such as a high-strength material (e.g., metal, engineering plastic), which has high rigidity, stability, and durability.

[0082] The first part 231 and the second part 232 are separately configured, meaning that the first part 231 and the second part 232 are manufactured and assembled separately but can be separated. For example, the liquid-conducting shell bottom 211 of the liquid-conducting shell 21 serves as the second part 232, and the liquid-conducting shell bottom 211 is connected to the first part 231 by fasteners, including but not limited to bolts, screws, etc.

[0083] In the embodiments of this application, the first part 231 and the connecting part 22 are configured as an integral structural component, which can improve the overall structural stability, reduce assembly steps, improve production efficiency, and reduce the risk of liquid leakage caused by loosening or wear of the connecting part 22. Moreover, the first part 231 and the second part 232 are set separately, allowing users to replace or upgrade a part individually as needed without replacing the entire liquid guiding component 2. The separate setting of the liquid guiding component 2 reduces the cost of use. In addition, the separate setting also facilitates cleaning and maintenance, especially when regular cleaning or replacement of vulnerable parts is required, the separate structure simplifies the operation process.

[0084] In some examples, the first part 231 and the connecting part 22 are integrally formed, both of which are cylindrical structures. The diameter of the connecting part 22 is smaller than the diameter of the first part 231, and the rigidity of the first part 231 and the connecting part 22 is greater than the rigidity of the first seal 24 and the second seal 25.

[0085] Thus, the first part 231 and the connecting part 22 are not easily deformed, serving as a supporting structure, improving the stability and sealing of the liquid flow channel structure, and are not prone to deformation, allowing the liquid to flow along the designed path. The first seal 24 and the second seal 25 seal the connection interface through elastic deformation, improving the sealing performance.

[0086] In some embodiments, such as Figure 5 As shown, the flow area of ​​the first liquid flow channel 223 is the same at all points, the flow area of ​​the second liquid flow channel 233 is the same at all points, and the flow area of ​​the first liquid flow channel 223 is the same as that of the second liquid flow channel 233.

[0087] The consistent flow area throughout the first liquid flow channel 223 ensures stable liquid flow at both flow rate and pressure. Similarly, the consistent flow area throughout the second liquid flow channel 233 enables stable liquid flow at both flow rate and pressure. This consistency between the flow areas of the first and second liquid flow channels 223 and 233 ensures uniform liquid transfer during the liquid delivery process, thereby improving the stability and consistency of liquid transport.

[0088] In some embodiments, such as Figure 5 As shown, the sum of the flow areas of all the first liquid channels 223 is less than or equal to the flow area of ​​the liquid outlet (e.g., the liquid outlet of the second liquid guide tube 133 described later).

[0089] In the embodiments of this application, by setting the flow area of ​​the liquid outlet to be greater than or equal to the total flow area of ​​the first liquid flow channel 223, the liquid can be distributed to each of the first liquid flow channels 223 with a sufficient flow rate after entering the liquid guide 2, thereby improving the balance of the flow distribution and providing stability of the liquid outlet.

[0090] In some embodiments, such as Figure 1 , Figure 2 , Figure 5 , Figure 7 and Figure 8 As shown, the liquid supply module includes a liquid storage tank 120 and a pump module 13. The liquid outlet is located on the pump module 13. The pump module 13 is configured to pump the nursing liquid in the liquid storage tank 120 into each first liquid flow channel 223, so that the nursing liquid flows through each second liquid flow channel 233 and flows out from each liquid outlet 2334.

[0091] Since the massage comb includes the liquid guiding element 2 provided in the first aspect, the massage comb can promote the miniaturization of the structure and increase the liquid distribution area.

[0092] In some embodiments of this application, such as Figures 1 to 8 , Figure 11 and Figure 12 As shown, a massage comb is provided. The massage comb includes a massage comb body 100 and at least one functional module 200. The massage comb body 100 includes a main unit 1, which includes a liquid storage tank 120 and a pump module 13. The pump module 13 is connected to the liquid storage tank 120. One of the functional modules 200 can be detachably connected to the main unit 1. At least one of the functional modules 200 is a liquid guide 2. The liquid guide 2 has a liquid guide channel with a liquid guide inlet 221 and a liquid guide outlet 2334. When the liquid guide 2 is connected to the main unit 1, the liquid guide channel is connected to the pump module 13 through the liquid guide inlet 221. The pump module 13 is configured to pump the nursing liquid in the liquid storage tank 120 into the liquid guide channel so that the nursing liquid flows out through the liquid guide outlet 2334.

[0093] For example, the liquid guiding channel includes first liquid flow channels 223 and second liquid flow channels 233. The liquid inlet 221 of the first liquid flow channel 223 is the liquid inlet 221 of the liquid guiding channel, and the liquid outlet 2334 of the second liquid flow channel 233 is the liquid outlet 2334 of the liquid guiding channel. That is, the liquid guiding channel includes multiple liquid guiding branches, and each liquid guiding branch includes connected first liquid flow channels 223 and second liquid flow channels 233.

[0094] For example, the portion of the connecting part 22 of the liquid guide 2 that extends out of the liquid guide housing cover 212 is in communication with the pump module 13.

[0095] In some examples, such as Figure 11 As shown, the massage comb body 100 also includes a housing 10 and a battery (not shown in the figure). At least a portion of the battery and the main unit 1 are disposed within the housing 10. The main unit 1 is electrically connected to the battery, which powers the main unit 1. After the functional module 200 is connected to the main unit 1, the resulting overall structure can operate to realize the scalp care function of the functional module 200. Optionally, the main unit 1 can be installed in the housing 10 by means of detachable means such as snap-fit, plug-in, or fasteners, or by means of non-detachable means such as welding, fusion, riveting, interference fit, or bonding.

[0096] In some examples, such as Figure 11 and Figure 12As shown, the housing 10 of the massage comb is connected with comb teeth 20, which surround the outer periphery of the main unit 1. When the liquid guide 2 is connected to the main unit 1, the comb teeth 20 surround the outer periphery of the liquid guide 2 and contact the scalp. The care liquid flowing out from the liquid guide outlet 2334 can be applied to the user's scalp for massage care.

[0097] It is understood that the liquid storage tank 120 is a compartment used to store care liquids. Care liquids may include, but are not limited to, essential oils, medicinal solutions, etc.

[0098] It should be noted that the liquid guiding component 2 may not contain any electrical components. In this case, after being removed from the main unit 1, the liquid guiding component 2 can be cleaned with cleaning fluid, making maintenance more convenient. Of course, it is understandable that an electrical component can be included in the liquid guiding component 2 to perform functions other than liquid guiding. When an electrical component is included, the liquid guiding component 2 can be cleaned by wiping or unclogging.

[0099] It should be noted that there is one or more functional modules 200. When there are multiple functional modules 200, one of the multiple functional modules 200 can be connected to the host 1. That is, the host 1 has only one installation part for connecting to the functional module 200.

[0100] In the embodiments of this application, "multiple" means two or more.

[0101] The massage comb provided in this embodiment allows for easy removal of the functional module 200 by detachably connecting it to the main unit 1, facilitating cleaning, maintenance, or replacement. Therefore, the liquid guide 2, as part of the functional module 200, can be detached from the main unit 1, allowing for easy unblocking of its channels and improving maintenance convenience. Furthermore, in this embodiment, the liquid storage tank 120 and pump module 13 are integrated into the main unit 1, simplifying the structure of the liquid guide 2 and facilitating its maintenance. Moreover, since no electrical components are present in the liquid guide 2, it can be cleaned with liquid, further enhancing maintenance convenience. Additionally, when the massage comb has other functional modules 200 besides the liquid guide 2, these modules can be flexibly combined with the main unit 1 to achieve multi-functionality.

[0102] In some embodiments, such as Figures 7 to 9As shown, the main unit 1 also includes a main unit housing 11, which has a receiving cavity. The main unit housing 11 includes a first shell wall 111. The main unit 1 also includes a bulkhead body 121, which is housed in the receiving cavity. The bulkhead body 121 has a first opening 1211 and a second opening 1212 at both ends along the first direction X. The first shell wall 111 covers the first opening 1211. The first shell wall 111 and the bulkhead body 121 form a liquid storage tank 120. The pump module 13 is disposed in the receiving cavity and located outside the liquid storage tank 120, and communicates with the second opening 1212 of the bulkhead body 121.

[0103] The main casing 11 is an external structural component used to enclose the internal components of the main unit 1. The main function of the main casing 11 is to protect the internal components from external environmental influences and to provide overall structural support. The receiving cavity refers to the cavity formed inside the main casing 11, used to house core components such as the liquid storage tank 120 and the pump module 13. The first shell wall 111 is part of the main casing 11 and also serves to seal the first opening 1211 of the main body 121, forming a closed structure to reduce leakage of the nursing fluid within the liquid storage tank 120.

[0104] The bulkhead body 121 is the main container for holding the nursing fluid, and is typically made of a material with a certain degree of rigidity to ensure the stability of the stored fluid. The first opening 1211 and the second opening 1212 are the openings for the fluid to enter and exit the bulkhead body 121, respectively. The first shell wall 111 closes the first opening 1211, providing a seal and reducing the chance of leakage. By using the first shell wall 111 in conjunction with the bulkhead body 121, they together form the boundary structure of the storage tank 120, giving the storage tank 120 good sealing performance and structural integrity. The boundary structure of the storage tank 120 formed by the first shell wall 111 and the bulkhead body 121 allows the storage tank 120 to be stably integrated into the main unit 1, while also facilitating subsequent pumping operations.

[0105] The pump module 13 is an actuator used to extract nursing fluid from the storage tank 120 and deliver it to a designated location. It may include components such as a diaphragm pump and a check valve. Positioning the pump module 13 within the receiving cavity but outside the storage tank reduces the space occupied inside the storage tank 120 and facilitates maintenance and replacement. The pump module 13 communicates with the second opening 1212 of the main body 121, creating a fluid transfer path between them, allowing fluid to flow smoothly out of the storage tank 120. This layout not only improves space utilization but also enhances reliability and functionality.

[0106] For example, the first shell wall 111 can be opened and closed to cover the first opening 1211. When it is necessary to add nursing fluid, the first shell wall 111 can be opened to open the first opening 1211, and nursing fluid can be added into the bulkhead body 121 through the first opening 1211. After the fluid is added, the first shell wall 111 is used to close the first opening 1211.

[0107] In the embodiments of this application, a receiving cavity is formed in the main body housing 11, and the bulkhead body 121 and the pump module 13 are disposed within the receiving cavity. The bulkhead body 121 and the first shell wall 111 of the main body housing 11 form a liquid storage tank 120, thereby integrating the liquid storage tank 120 and the pump module 13 into the main body 1, which simplifies the structure of the functional module 200. Moreover, by placing the pump module 13 outside the bulkhead body 121, the pump module 13 avoids occupying the liquid storage tank 120, thereby increasing the liquid storage capacity and optimizing the internal layout. At the same time, the first shell wall 111 covers the first opening 1211 and forms a closed structure, reducing the probability of liquid leakage. Furthermore, the first shell wall 111 serves as both one of the shell walls of the main body housing 11 and part of the bulkhead of the liquid storage tank 120, saving sheet metal, which is beneficial for material conservation and miniaturization of the main body 1.

[0108] In some embodiments, such as Figure 7 and Figure 8 As shown, the main unit housing 11 also includes a second housing wall 112 and a housing body 113. The second housing wall 112 and the first housing wall 111 are arranged opposite to each other along the first direction X. The housing body 113 is connected between the first housing wall 111 and the second housing wall 112 and forms a receiving cavity. At least a portion of the pumping module 13 is provided on the side of the bulkhead body 121 facing the second housing wall 112. When the liquid guiding component 2 is connected to the main unit 1, the liquid guiding module 13 is connected to the second housing wall 112.

[0109] For example, the shell body 113 is a sleeve-shaped structure with openings at both ends along the first direction X. The second shell wall 112 and the first shell wall 111 respectively close the two openings of the shell body 113 that are opposite each other along the first direction X, forming a receiving cavity. The shell body 113 can be, but is not limited to, a circular sleeve, a square sleeve, or a sleeve-shaped structure of other shapes. It should be noted that a circular sleeve refers to a sleeve with a circular cross-section, and a square sleeve refers to a sleeve with a square ring cross-section.

[0110] The main unit casing 11 can be made of high-strength plastic or metal, possessing good rigidity and resistance to deformation. Furthermore, the main unit casing 11 can be equipped with a magnetic or snap-fit ​​structure to enable a detachable connection between the main unit 1 and the functional module 200.

[0111] In the embodiments of this application, by combining the first shell wall 111, the shell body 113, and the second shell wall 112 to form a receiving cavity, the sealing and protection of the main unit shell 11 can be improved, effectively isolating the external environment from the components inside the receiving cavity, thereby extending the service life of the main unit 1. Furthermore, at least a portion of the pump module 13 is arranged on the side of the bulkhead body 121 near the second shell wall 112, which helps optimize the internal space layout, making the overall structure more compact, reducing unnecessary volume occupation, and facilitating the miniaturization of the main unit 1. In addition, arranging the pump module 13 near the second shell wall 112 also facilitates the docking of the pump module 13 with the liquid outlet (second opening 1212) of the liquid storage tank 120, improving liquid delivery efficiency.

[0112] In some embodiments, such as Figure 5 , Figure 7 and Figure 9 As shown, the second shell wall 112 has a first through hole 1121. The pump module 13 includes a pump assembly 131, a first liquid guide pipe 132 and a second liquid guide pipe 133. The pump assembly 131 is connected to the shell body 113 and / or the second shell wall 112. The two ends of the first liquid guide pipe 132 are respectively connected to the liquid inlet end of the pump assembly 131 and the second opening 1212. The two ends of the second liquid guide pipe 133 are respectively connected to the liquid outlet end of the pump assembly 131 and the first through hole 1121. When the liquid guide 2 is connected to the main unit 1, the liquid inlet 221 is connected to the second liquid guide pipe 133 through the first through hole 1121. The first liquid guide pipe 132 and the second liquid guide pipe 133 are located on the same side of the pump assembly 131 along the second direction Y that intersects the first direction X. The first liquid guide pipe 132 is located on the side of the second liquid guide pipe 133 facing the bulkhead body 121 along the first direction X.

[0113] The first through hole 1121 refers to a channel structure opened on the outer surface of the second shell wall 112, used to guide the nursing liquid inside the pump fluid module 13 to the external environment. The first through hole 1121 not only serves a connection function, but also ensures the stability and sealing of the liquid flow. By setting the first through hole 1121, efficient connection between the pump fluid module 13 and the liquid guide 2 can be achieved, improving the reliability of the massage comb.

[0114] Pump assembly 131 is the core component of the pump-liquid module 13, used to power the flow of liquid. Exemplarily, pump assembly 131 consists of a diaphragm pump driven by piezoelectric ceramic 13113. Under the action of an alternating electric field, the piezoelectric ceramic 13113 deforms, driving the diaphragm to move periodically, thereby generating suction and pressure. Pump assembly 131 can be fixed to the main body 113 or the second shell wall 112 to enhance structural stability and reduce the impact of pump assembly 131 vibration on other modules. Using piezoelectric ceramic 13113 as the driving source has advantages such as small size, low power consumption, and fast response speed, which is beneficial for the miniaturization of the main unit 1.

[0115] The first liquid guide tube 132 is used to transport the nursing liquid from the outlet (second opening 1212) of the liquid storage tank 120 to the inlet end of the pump assembly 131, and the second liquid guide tube 133 is used to transport the nursing liquid from the outlet end of the pump assembly 131 to the first through hole 1121, thereby transporting the nursing liquid to the liquid guide channel of the liquid guide member 2, and then transporting it to the part of the human body that needs massage through the liquid guide outlet 2334 of the liquid guide channel.

[0116] For example, such as Figure 7 and Figure 9 As shown, a third sealing element 18 is provided between the portion of the second liquid guide tube 133 that extends into the first through hole 1121 and the wall of the first through hole 1121.

[0117] For example, one end of the second liquid guide tube 133 that extends into the first through hole 1121 serves as the liquid outlet of the main unit 1. That is, the part of the connecting part 22 of the liquid guide member 2 that extends out of the liquid guide shell cover 212 extends into the second liquid guide tube 133 through the first through hole 1121, and part of the first sealing member 24 that is sleeved on the outer periphery of the connecting part 22 seals between the outer peripheral surface of the connecting part 22 and the inner wall of the second liquid guide tube 133.

[0118] In the embodiments of this application, the pump assembly 131 provides power for the flow of nursing fluid. The first liquid guide tube 132 and the second liquid guide tube 133 construct the fluid path. The first through hole 1121 serves as an external connection port, and the liquid guide inlet 221 serves as a bridge for the liquid to enter the liquid guide component 2. These components work together to complete the liquid transport process from the liquid storage tank 120 to the liquid guide outlet 2334 of the liquid guide component 2, thereby improving the reliability of the massage comb operation. Furthermore, the first liquid guide tube 132 and the second liquid guide tube 133 are arranged on the same side of the pump assembly 131 along the second direction Y to save space and optimize the flow channel layout. The arrangement of the first liquid guide tube 132, the second liquid guide tube 133, and the pump assembly 131 helps to shorten the fluid path, reduce bends and resistance, thereby improving the liquid transmission efficiency. Moreover, it also reduces the space waste caused by the interlacing of liquid guide tubes and facilitates later maintenance.

[0119] In some embodiments, such as Figure 7 and Figure 9 As shown, the main unit 1 also includes a main control board 14, which is housed in the receiving cavity and electrically connected to the pump assembly 131. The main control board 14 is located on the side of the bulkhead body 121 away from the first shell wall 111, and at least partially on the side of the pump assembly 131 where the second liquid guide pipe 133 is provided along the second direction Y. The main control board 14 has a clearance opening 1411 through which the second liquid guide pipe 133 passes.

[0120] The main control board 14 is the core circuit board used to control the operation of various electrical modules (such as the pump assembly 131 and various functional modules 200) of the massage comb. The main control board 14 is electrically connected to the pump assembly 131 via circuit wiring. The main control board 14 can precisely control the start / stop and flow rate adjustment of the pump assembly 131. It can start or stop the pump assembly 131 according to user commands or preset programs, and adjust the pump speed according to actual needs to precisely control the liquid output. Simultaneously, the operating status of the pump assembly 131 can be fed back to the main control board 14 for real-time monitoring and fault detection, further improving the system's intelligence level. The main control board 14 coordinates the data interaction and logical control between the electrical modules, thereby ensuring the massage comb operates stably and efficiently. In this embodiment, the main control board 14 is placed inside the housing cavity of the main unit 1. This design reduces the occupation of external space and enhances the integration of the main unit 1.

[0121] In this embodiment, the main control board 14 is arranged on the side of the bulkhead 121 facing away from the first shell wall 111, and a portion of the main control board 14 extends to the side of the pump assembly 131 where the second liquid guide pipe 133 is provided along the second direction Y. This layout not only saves space but also reduces the signal transmission distance, which is beneficial for improving circuit response speed and anti-interference capability. Furthermore, the main control board 14 is provided with a clearance opening 1411, allowing the second liquid guide pipe 133 to pass through without interfering with the layout and function of the main control board 14. The clearance opening 1411 allows the second liquid guide pipe 133 to pass reasonably through the main control board 14, avoiding excessive bending or damage to the second liquid guide pipe 133 due to physical interference, thereby improving the smoothness and stability of the liquid delivery path. In addition, the clearance opening 1411 simplifies the wiring path, reduces assembly difficulty, and improves production efficiency.

[0122] In some embodiments, such as Figures 8 to 10As shown, the pump assembly 131 includes a pump body 1311 and two one-way valve diaphragms 1312. The pump body 1311 includes a pump housing 13111, a pump bottom cover 13112, a piezoelectric ceramic 13113, a first pump bag diaphragm 13114, and a second pump bag diaphragm 13115. The pump bottom cover 13112 and the pump housing 13111 are enclosed along the second direction Y to form the pump cavity. The pump housing 13111 and the pump bottom cover 13112 are both connected to the second shell wall 112 of the main unit 1 by fasteners. The first pump bag film 13114 and the second pump bag film 13115 are assembled together to form a pump bag with a sealed cavity. A piezoelectric ceramic 13113 is connected to the surface of the first pump bag film 13114 facing away from the second pump bag film 13115. The surface of the piezoelectric ceramic 13113 facing away from the first pump bag film 13114 faces the inner surface of the pump bottom cover 13112. Two convex rings 13110 arranged along the first direction X are formed on the surface of the pump housing 13111 facing away from the pump bottom cover 13112. Both convex rings 13110 communicate with the pump cavity. Each of the two convex rings 13110 of the pump housing 13111 is connected to a... A connecting pipe 1313 is connected to the first liquid guide pipe 132 and the second liquid guide pipe 133 respectively. A convex ring 13110, located away from the second shell wall 112 along the first direction X, forms a receiving space with one of the connecting pipes 1313. A one-way valve diaphragm 1312 is installed in this receiving space. A convex ring 13110, located closer to the second shell wall 112 along the first direction X, forms another receiving space with another connecting pipe 1313. Another one-way valve diaphragm 1312 is installed in this receiving space, and the two one-way valve diaphragms 1312 are assembled in opposite directions. The piezoelectric ceramic 13113 is electrically connected to the main control board 14. An annular sealing gasket 1314 is sandwiched between the end face of the convex ring 13110 and the connecting pipe 1313.

[0123] Thus, when the pump assembly 131 is working, the piezoelectric ceramic 13113 inside the pump body 1311 deforms, causing the first pump bag diaphragm 13114 to deform. When it bulges, a negative pressure is generated inside the pump cavity. At this time, because the two one-way valve diaphragms 1312 are assembled in opposite directions, the one-way valve diaphragm 1312 near the second shell wall 112 deforms and sticks to the wall of the pump housing 13111, closing the liquid passage, while the one-way valve diaphragm 1312 away from the second shell wall 112 opens to form a passage, drawing the nursing liquid from the reservoir 120 into the pump body 1311. Subsequently, the deformation of the piezoelectric ceramic 13113 causes the first pump bag diaphragm 13114 to deform. When it is concave, a positive pressure is generated in the pump cavity. At this time, the one-way valve diaphragm 1312 near the second shell wall 112 deforms and sticks to the wall of the connecting pipe 1313 to form a passage, and the one-way valve diaphragm 1312 away from the second shell wall 112 deforms and sticks to the wall of the connecting pipe 1313 to close the liquid passage. Therefore, the liquid in the pump cavity is pumped into the second liquid guide pipe 133, and the liquid enters the liquid guide component 2 through the second liquid guide pipe 133.

[0124] For example, the flow area of ​​the second liquid guide tube 133 is greater than the sum of the flow areas of all liquid guide inlets 221 of the connecting part 22. Therefore, a certain positive pressure is generated, which improves the stability of liquid discharge and realizes the function of liquid discharge at any angle except the inverted angle.

[0125] In some embodiments, such as Figure 9 As shown, the first shell wall 111 has vent holes 1114 that penetrate its inner and outer walls, and the vent holes 1114 are covered with a waterproof and breathable membrane 1115.

[0126] The vent 1114 refers to a channel provided on the main unit housing 11 for adjusting the internal air pressure balance. The vent 1114 penetrates the inner and outer walls of the first housing wall 111, allowing gas to flow between the inside and outside of the first housing wall 111, thereby reducing the probability of unstable liquid flow velocity due to changes in internal pressure.

[0127] For example, such as Figure 8 and Figure 9 As shown, the first shell wall 111 includes an outer wall 1111 and an inner wall 1112. The outer wall 1111 is closed at one end opening of the shell body 113, and is in contact with and connected to the end face of the shell body 113 with the opening. An annular protrusion 1116 is formed on the inner surface of the outer wall 1111. The annular protrusion 1116 is inserted into the first opening 1211 of the bulkhead body 121. A sealing structure 114 is provided between the outer peripheral surface of the annular protrusion 1116 and the inner surface of the first opening 1211. The sealing structure 114 can be, but is not limited to, a sealing ring. The inner wall 1112 is connected to the outer wall 1111 in the area surrounded by the annular protrusion 1116. The inner wall 1112 and the outer wall 1111 are welded together by ultrasonic process. Both the outer wall 1111 and the inner wall 1112 have through holes, and the two through holes are aligned and connected to form the vent 1114. A waterproof and breathable membrane 1115 is sandwiched between the outer wall 1111 and the inner wall 1112, and the waterproof and breathable membrane 1115 completely covers the two through holes.

[0128] The waterproof and breathable membrane 1115 is a polymer film with a microporous structure that allows gas to pass through but prevents liquid from penetrating. In this embodiment, the waterproof and breathable membrane 1115 covers the vents 1114. The waterproof and breathable membrane 1115 prevents external moisture or liquid from entering the equipment, while maintaining stable internal air pressure, thereby ensuring the equipment's sealing and functionality.

[0129] In the embodiments of this application, by providing vents 1114 with a waterproof and breathable membrane 1115 on the first shell wall 111, the pressure difference between the inside and outside of the liquid storage tank 120 can be effectively balanced, reducing the problem of liquid overflow or deformation of the liquid storage tank 120 caused by pressure changes. The waterproof and breathable membrane 1115 not only improves the smoothness of gas flow but also prevents liquid leakage, thereby enhancing the safety and durability of the main unit 1.

[0130] In some embodiments, such as Figure 9 , Figure 15 and Figure 18 As shown, the second shell wall 112 has a second through hole 1122. The main unit 1 also includes a main control board 14, which is housed in the receiving cavity and located on the side of the bulkhead body 121 away from the first shell wall 111. The main control board 14 includes a main base plate 141 and a first plug-in terminal block 142 disposed on the side of the main base plate 141 away from the bulkhead body 121. At least a portion of the first plug-in terminal block 142 extends into the second through hole 1122. There are multiple functional modules 200. At least one of the functional modules 200 is an electrical module. The electrical module has a second plug-in terminal block 324. When the electrical module is connected to the main unit 1, the second plug-in terminal block 324 is plugged into the first plug-in terminal block 142.

[0131] For example, the main control board 14 includes a main base plate 141, on which key components such as a microcontroller, a power management chip, and a signal conditioning circuit are integrated, and are connected to the first pair of plug-in terminal blocks 142 and the pump assembly 131 through lines.

[0132] The first pair of plug-in terminal blocks 142 is an electrical connection interface on the main control board 14, used for electrical connection with external power modules (such as phototherapy module 3 and laser module 4). The first pair of plug-in terminal blocks 142 has a pluggable terminal structure, which enables quick assembly and disassembly and stable connection, improving the maintainability and reliability of the massage comb. The specific structure of the first pair of plug-in terminal blocks 142 can be found in existing technology and will not be described in detail here.

[0133] Power-consuming modules refer to the modules in the functional modules 200 connected to the host 1 that require power to perform specific functions, such as phototherapy module 3 and laser module 4. Power-consuming modules typically include power-consuming components such as LED lights 323, lasers, and drive circuits. Therefore, power-consuming modules need to establish a stable power and signal connection with the main control board 14.

[0134] The second pair of plug-in terminal blocks 324 is an electrical connection interface on the power module. The structure of the second pair of plug-in terminal blocks 324 matches that of the first pair of plug-in terminal blocks 142, enabling physical and electrical connection.

[0135] For example, of the first mating terminal block 142 and the second mating terminal block 324, one is a mating terminal female block and the other is a mating terminal male block.

[0136] For example, such as Figure 15 As shown, the main unit 1 also includes a third pair of plug-in terminals 15 and a conductive wire 16. The third pair of plug-in terminals 15 is connected to the shell body 113 of the main unit housing 11. The plug-in terminals of the third pair of plug-in terminals 15 extend out of the shell body 113 and extend in the first direction X toward the direction close to the second shell wall 112. One end of the conductive wire 16 is electrically connected to the third pair of plug-in terminals 15, and the other end is electrically connected to the surface of the main base plate 141 of the main control board 14 away from the first electrical plug-in. The third pair of plug-in terminals 15 is used for electrical connection with the battery.

[0137] For example, the shell body 113 has a mounting groove formed near the first shell wall 111, and the third pair of plug-in terminal blocks 15 are fixed in the mounting groove by a potting process.

[0138] For example, the first shell wall 111 and the second shell wall 112 are bonded to the end faces of the shell body 113 with adhesive to improve the waterproof effect.

[0139] In the embodiments of this application, when the power module is inserted into the host 1, the second pair of plug-in terminals 324 and the first pair of plug-in terminals 142 are mutually plugged in, thereby completing the circuit connection. This connection method of mutual plugging of the second pair of plug-in terminals 324 and the first pair of plug-in terminals 142 not only improves the stability of the connection but also reduces contact resistance, improves signal transmission efficiency and overall operational reliability. Furthermore, a portion of the first pair of plug-in terminals 142 extends into the second through hole 1122, providing a stable electrical connection interface for the power module, which is beneficial for improving the stability of the electrical connection. The operation of plugging in the second pair of plug-in terminals 324 and the first pair of plug-in terminals 142 is convenient and quick, reducing the convenience and reliability of the docking operation between the functional module 200 and the host 1. In addition, the embodiments of this application utilize the first pair of plug-in terminals 142 integrated on the main substrate 141 to achieve external connection, improving the integration and functionality of the host 1, simplifying the structure of the host 1, and facilitating subsequent upgrades and maintenance.

[0140] In some embodiments, such as Figures 13 to 15As shown, at least one of the power modules is a phototherapy module 3. The phototherapy module 3 includes a phototherapy housing 31 and a phototherapy mainboard 32 housed within the phototherapy housing 31. The phototherapy mainboard 32 includes a phototherapy substrate 321, an infrared lamp 322, an LED lamp 323, and a second pair of plug-in terminals 324. The infrared lamp 322 and the LED lamp 323 are connected to the same side of the phototherapy substrate 321, and the second pair of plug-in terminals 324 are connected to the other side of the phototherapy substrate 321. A third through hole 3121 is formed on the shell wall of the phototherapy housing 31 facing the second pair of plug-in terminals 324. At least a portion of the second pair of plug-in terminals 324 extends into the third through hole 3121. The shell wall of the phototherapy housing 31 facing the infrared lamp 322 is configured as a light-transmitting wall.

[0141] The phototherapy housing 31 refers to the external casing used to encapsulate and protect the phototherapy motherboard 32. The phototherapy housing 31 is typically made of an insulating and strong material, such as plastic or an engineering plastic alloy. The phototherapy housing 31 provides good physical protection for the internal components. Exemplarily, the phototherapy housing 31 includes a phototherapy shell 311 and a phototherapy shell cover 312. The phototherapy shell cover 312 is interlocked with the phototherapy shell 311 to form an inner cavity for accommodating the phototherapy motherboard 32. The phototherapy shell cover 312 has a third through hole 3121, and the shell wall of the phototherapy shell 311 facing the infrared lamp 322 is configured as a light-transmitting wall.

[0142] The phototherapy motherboard 32 is the core circuit component of the phototherapy module 3. For example, the phototherapy motherboard 32 includes key components such as a phototherapy substrate 321, an infrared lamp 322, an LED lamp 323, and a second pair of connectors 324. The phototherapy substrate 321 serves as the basic platform supporting all components. As the foundation platform of the phototherapy motherboard 32, the phototherapy substrate 321 is typically a high thermal conductivity PCB (printed circuit board) used for heat dissipation and fixing other electronic components.

[0143] Infrared lamp 322 is a light source that emits near-infrared light and is commonly used for health care functions such as promoting blood circulation and relieving muscle pain. Infrared lamp 322 has strong penetrating power. LED lamp 323 is a low-power, long-life, and fast-response light-emitting diode. In the embodiments of this application, infrared lamp 322 and LED lamp 323 are both mounted on the same side of phototherapy substrate 321 to achieve phototherapy effects of synchronous or alternating operation.

[0144] The second pair of plug-in terminal blocks 324 is an electrical interface used to connect the phototherapy motherboard 32 and the main control board 14 of the host 1. It can adopt a plug-in structure, which facilitates quick plugging and unplugging and improves the stability of signal transmission.

[0145] The third through hole 3121 refers to a through hole opened on the phototherapy housing 31, located on the housing wall corresponding to the second mating terminal block 324. The third through hole 3121 allows a portion of the second mating terminal block 324 to extend out of the phototherapy housing 31 for mating with the first mating terminal block 142 of the host 1. The third through hole 3121 improves the stability of the connection and avoids the phototherapy housing 31 from obstructing the external connection, thereby improving assembly efficiency and reliability.

[0146] A light-transparent wall refers to a portion of the phototherapy housing 31 that is made of a light-transmitting material or structure, allowing the light emitted by the internal infrared lamps 322 and LED lamps 323 to pass through the housing and illuminate the target area smoothly. The light-transmitting wall is typically made of transparent or translucent materials, such as polycarbonate (PC) or acrylic (PMMA). The position of the light-transmitting wall corresponds to the installation positions of the infrared lamps 322 and LED lamps 323; this design ensures a clear and efficient light output path.

[0147] In the embodiments of this application, by providing a third through hole 3121 and a light-transmitting wall on the phototherapy housing 31, a stable connection and effective light output of the phototherapy module 3 can be achieved. The third through hole 3121 allows the second pair of plug-in terminals 324 to smoothly connect with the host 1, while the light-transmitting wall allows the light from the infrared lamp 322 and the LED lamp 323 to be fully radiated, achieving the expected therapeutic effect. Furthermore, integrating the infrared lamp 322, the LED lamp 323, and the second pair of plug-in terminals 324 on the phototherapy substrate 321 improves the integration and connection reliability of the phototherapy module 3, which is beneficial for the miniaturization of the phototherapy module 3 and extending its service life. In addition, the second pair of plug-in terminals 324 is installed on the side of the phototherapy substrate 321 opposite to the infrared lamp 322 and the LED lamp 323, which helps to reduce electromagnetic interference and improve the overall compactness of the layout.

[0148] In some embodiments, such as Figures 16 to 18 As shown, at least one of the power modules is a laser module 4. The laser module 4 includes a laser housing 41 and a laser mainboard 42 housed within the laser housing 41. The laser mainboard 42 includes a laser substrate 421, a laser lamp 422, and a second pair of plug-in terminals 324. The laser lamp 422 is connected to one side of the laser substrate 421, and the second pair of plug-in terminals 324 is connected to the other side of the laser substrate 421. A fourth through hole 4121 is formed on the shell wall of the laser housing 41 facing the second pair of plug-in terminals 324. At least a portion of the second pair of plug-in terminals 324 extends into the fourth through hole 4121. A lens 43 is provided on the shell wall of the laser housing 41 facing the laser lamp 422.

[0149] The laser housing 41 is an external shell used to encapsulate and protect the internal components of the laser module 4. The laser housing 41 is typically made of insulating and high-temperature resistant material to ensure the safe operation of the laser source and circuitry. The laser housing 41 not only provides physical support but also serves as a dustproof enclosure. For example, the laser housing 41 includes a laser housing 411 and a laser housing cover 412. The laser housing cover 412 is interlocked with the laser housing 411 to form an inner cavity for accommodating the laser motherboard 42. The laser housing cover 412 has a fourth through hole 4121. A lens 43 is provided on the housing wall of the laser housing 411 facing the laser lamp 422.

[0150] The laser motherboard 42 is the core component of the laser module 4, integrating the laser lamp 422 and other electronic components, and controlling the laser output through circuit design. The laser substrate 421 serves as the base layer of the laser motherboard 42, and is typically a high thermal conductivity PCB (printed circuit board) used for heat dissipation and mounting other electronic components.

[0151] Laser lamp 422 is the light source in laser module 4, capable of emitting laser light of a specific wavelength. Laser lamp 422 is mounted on one side of laser substrate 421 and electrically connected by soldering or other fixing methods.

[0152] The second pair of terminal blocks 324 is a pluggable electrical connector used to establish a communication and power supply connection between the laser module 4 and the main control board 14 of the host 1. The second pair of terminal blocks 324 is located on the other side of the laser substrate 421, opposite to the laser lamp 422, which facilitates wiring and modular assembly.

[0153] The fourth through hole 4121 is a through hole opened in the laser housing 41 to allow a portion of the second pair of plug-in terminal blocks 324 to extend so as to mate with the first pair of plug-in terminal blocks 142 of the host 1. The setting of the fourth through hole 4121 not only improves the stability of the connection, but also avoids the laser housing 41 from obstructing the external connection, thereby improving assembly efficiency and reliability.

[0154] Lens 43 is an optical element mounted on the laser housing 41, facing the light-emitting surface of the laser lamp 422. It is used to focus or diffuse the laser beam, causing it to propagate along a preset path and improving the phototherapy effect. Lens 43 can be in the form of a convex lens or a concave lens, depending on the application scenario and optical path design requirements.

[0155] In this embodiment, by providing a fourth through hole 4121 and a lens 43 on the laser housing 41, a stable connection and effective light output of the laser module 4 can be achieved. The fourth through hole 4121 allows the second pair of plug-in terminals 324 to smoothly connect with the host 1, while the lens 43 ensures that the light from the laser lamp 422 propagates along a predetermined path, achieving the desired therapeutic effect. Furthermore, integrating the laser lamp 422 and the second pair of plug-in terminals 324 into the laser substrate 421 improves the integration and connection reliability of the laser module 4, facilitating miniaturization and extending the service life of the laser module 4. In addition, the second pair of plug-in terminals 324 is mounted on the side of the laser substrate 421 opposite to the laser lamp 422, which helps reduce electromagnetic interference and improves the overall compactness of the layout.

[0156] In some embodiments, such as Figure 2 , Figure 14 and Figure 17 As shown, the host 1 also includes a first magnetic absorbing member 17, which is connected to the inner wall of the second shell 112. Each functional module 200 has a second magnetic absorbing member 33, which is magnetically attracted to the first magnetic absorbing member 17.

[0157] For example, the connection between the first magnetic member 17 and the second shell wall 112 includes snap-fit ​​and / or adhesive bonding. The connection between the second magnetic member 33 and the shell of the functional module 200 includes snap-fit ​​and / or adhesive bonding.

[0158] The first magnetic element 17 refers to a magnetic component installed on the internal structure of the host 1 (such as the second shell wall 112) to achieve magnetic connection between the host 1 and each functional module 200. The first magnetic element 17 can be made of permanent magnet material and embedded in the limiting groove 1123 of the shell, so that the position of the magnetic element is fixed and not exposed, while having sufficient adsorption force.

[0159] The second magnetic component 33 refers to the magnetic element disposed on each detachable functional module 200 (such as the liquid guide 2, phototherapy module 3, laser module 4, etc.), used to magnetically engage with the first magnetic component 17 in the main unit 1. The second magnetic component 33 can be made of permanent magnet material and set into a suitable shape and size according to the module structure to match the first magnetic component 17 of the main unit 1.

[0160] In practical use, for example, when a user needs to replace the phototherapy module 3, they only need to bring the phototherapy module 3 close to the bottom of the main unit 1. The second magnetic component 33 in the phototherapy module 3 will automatically align with and attract the first magnetic component 17 of the main unit 1, allowing the user to complete the quick installation. During this process, the second pair of plug-in terminals 324 in the phototherapy module 3 will also automatically align with and establish an electrical connection with the first pair of plug-in terminals 142 of the main control board 14 of the main unit 1, making the docking operation convenient and quick.

[0161] In some examples, such as Figure 14 As shown, the phototherapy module 3 includes a second magnetic member 33, which is connected to the inner wall of the housing wall facing the second plug-in terminal 324 of the phototherapy housing 31. This ensures that when the phototherapy module 3 is connected to the main unit 1, the second magnetic member 33 is closer to the first magnetic member 17, improving the reliability of the magnetic connection between the phototherapy module 3 and the main unit 1.

[0162] In some examples, such as Figure 17 As shown, the laser module 4 includes a second magnetic 33, which is connected to the inner wall of the housing wall facing the second plug-in terminal block 324 of the laser housing 41. This ensures that when the laser module 4 is connected to the host 1, the second magnetic 33 is closer to the first magnetic 17, improving the reliability of the magnetic connection between the laser module 4 and the host 1.

[0163] In some examples, such as Figure 2 and Figure 3 As shown, the liquid guiding component 2 includes a second magnetic suction component 33, and the inner wall of the liquid guiding shell cover 212 of the liquid guiding shell 21 is connected to the second magnetic suction component 33.

[0164] In the embodiments of this application, when the functional module 200 approaches the host 1, the second magnetic member 33 and the first magnetic member 17 attract each other, achieving rapid positioning and stable connection, so that the functional module 200 and the host 1 are connected. Since the first magnetic member 17 and the second magnetic member 33 adopt a magnetic attraction method, this magnetic attraction method not only improves the user experience, but also reduces the frictional wear between the functional module 200 and the host 1, and further extends the service life of the entire massage comb. In addition, the first magnetic member 17, the first through hole 1121 and the second through hole 1122 are all provided on the second shell wall 112, which allows the host 1 and the functional module 200 to be connected in a way that the second shell wall 112 and the shell wall of the functional module 200 with the second plug-in terminal 324 are close to each other, which is beneficial to improve the stability and reliability of electrical connection and hydraulic connection, and improve the magnetic reliability.

[0165] In some examples, such as Figure 9 As shown, in the host 1, a first through hole 1121 is formed at the middle position of the second shell wall 112, a second liquid guide tube 133 is provided on one side of the pump assembly 131 along the second direction Y, and the end of the second liquid guide tube 133 away from the pump assembly 131 extends into the first through hole 1121. A first plug-in terminal block 142 is provided on the side of the second liquid guide tube 133 away from the second liquid guide tube 133 along the second direction Y. At least one first magnetic suction member 17 is provided on each of the opposite sides of the second liquid guide tube 133 along the third direction Z. The first magnetic suction member 17 is connected to the second shell wall 112.

[0166] Thus, by rationally arranging the positions of the second liquid guide pipe 133, pump assembly 131, first magnetic suction component 17, and first plug-in terminal block 142, space support is provided for the connection of the liquid circuit and the circuit, while ensuring that the installation of the magnetic suction component does not interfere with other structures, optimizing the overall layout and improving the compactness of the main unit 1. This is beneficial for the miniaturization of the main unit 1.

[0167] In some examples, such as Figure 7 As shown, the outer surface of the second shell wall 112 of the main unit housing 11 has a groove 1124 and / or a protrusion 2122, and the outer surface of each functional module 200 has a protrusion 2122 and / or a groove 1124. The main unit housing 11 and the functional module 200 are engaged by the protrusion 2122 and the groove 1124.

[0168] For example, the outer surface of the phototherapy housing cover 312 of the phototherapy housing 31 is formed with protrusions 2122 and / or grooves 1124.

[0169] For example, the outer surface of the laser housing cover 412 of the laser housing 41 is formed with protrusions 2122 and / or grooves 1124.

[0170] For example, the outer surface of the liquid-conducting housing 21's liquid-conducting housing cover 212 is formed with protrusions 2122 and / or grooves 1124.

[0171] The protrusion 2122 and the groove 1124 work together to position and fix the parts, thereby improving the stability of the connection and the assembly efficiency.

[0172] The above description is merely an embodiment of this application and is not intended to limit the scope of protection of this application. Any modifications, equivalent substitutions, and improvements made within the spirit and scope of this application are included within the scope of protection of this application.
