Description

Technical Field

[0001] This application belongs to the technical field of massage devices, and particularly relates to a handheld percussion massager and its percussion massage mechanism. Background Art

[0002] With the acceleration of the modern life rhythm, people are increasingly suffering from muscle fatigue and tension. In a massage method, significant effects can be obtained by relieving muscle fatigue through percussion. Therefore, handheld percussion massage devices have been introduced on the market. This percussion massage device is similar to a massage stick, which can be held with one hand and easily extended to the shoulder area for massage. The massage device is equipped with a pair of percussion heads. The pair of percussion heads has a structure similar to a seesaw. Driven by a drive mechanism, the two percussion heads can swing up and down, thus realizing continuous percussion actions. Since the strokes of the two percussion heads are unified and the force output is uniform, the overall massage force is similar, so an effective massage effect can be achieved.

[0003] In practical applications, due to the small volume of the entire massage device, the pair of percussion heads that realize the seesaw movement are compactly arranged with the drive mechanism. Therefore, during the movement of the pair of percussion heads, they are prone to collide with the drive mechanism, resulting in noise and affecting the use experience.

[0004] It can be seen that the existing handheld percussion massage devices still have many defects, which are research problems that massage device manufacturers urgently need to solve at present. Summary of the Invention

[0005] The purpose of the embodiments of this application is to provide a percussion massager and its percussion massage mechanism to solve the technical problem that the movement of the percussion heads on the existing handheld massager is prone to collision, resulting in noise.

[0006] To achieve the above purpose, the technical solution adopted in this application is: to provide a percussion massage mechanism, including:

[0007] A pair of percussion heads, with a connecting bridge between the pair of percussion heads. The pair of percussion heads are symmetrically connected to both ends of the connecting bridge, and a central axis is provided on the connecting bridge;

[0008] A drive mechanism, including a motor, a motor base, and a connecting rod. The connecting rod is connected to the percussion head; the motor is arranged on the motor base and is connected to the connecting rod through an eccentric structure; the motor drives the connecting rod to drive the pair of percussion heads to swing around the central axis of the connecting bridge;

[0009] The first elastic member is disposed between the motor base and the connection bridge. The first elastic member is compressed and undergoes telescopic deformation as the pair of striking heads swing, thereby preventing the connection bridge and the motor base from colliding with each other and effectively playing a sound insulation role.

[0010] Make an improvement to the structure of the first elastic member. The first elastic member includes a pair of elastic blocks made of soft plastic material. The pair of elastic blocks are respectively disposed on both sides of the central axis of the connection bridge and abut between the motor base and the connection bridge. By using the telescopic deformation of the elastic blocks when being compressed, it can not only play a buffering role but also keep the pair of striking heads and the driving mechanism in a compact setting.

[0011] In one embodiment, the connection bridge is provided with fixing grids on both sides of the central axis, the motor base is provided with fixing grooves corresponding to the positions of the fixing grids, and both ends of the elastic block are respectively embedded in the fixing grids and the fixing grooves to ensure the fixing effect on the elastic block.

[0012] In one embodiment, one end of the elastic block for embedding in the fixing grid is an arc surface, so that the elastic block can adaptively change direction in the fixing grid according to the movement track of the connection bridge, thereby improving the movement flexibility of the connection bridge.

[0013] Make another improvement to the structure of the first elastic member. The first elastic member includes a pair of springs. The pair of springs are respectively disposed on both sides of the central axis of the connection bridge; one end of the spring is connected to the connection bridge, and the other end of the spring is connected to the motor base. By using the telescopic deformation of the springs when being compressed, it can not only play a buffering role but also keep the pair of striking heads and the driving mechanism in a compact setting.

[0014] Make an improvement to the structure of the striking heads. The inner parts of the pair of striking heads are respectively provided with heating components. The heating components include a second elastic member, a heating sheet, and a heat conduction block. The heat conduction block is attached to the output end of the striking head; the second elastic member presses the heating sheet against the heat conduction block; a mica sheet for insulation is also provided between the heating sheet and the heat conduction block. In this way, it not only ensures the effective transfer of heat but also avoids the risk of direct contact between high temperature and the user's skin causing burns, effectively ensuring the use safety of the massager.

[0015] In one embodiment, the connecting rod is connected to one of the pair of striking heads. One end of the second elastic member abuts against the heating sheet, and an elastic ring is provided at the other end of the second elastic member. The connecting rod is sleeved on the elastic ring. By using the elastic deformation characteristic of the elastic ring, a flexible connection is achieved between the connecting rod and the striking head, thereby improving the movement flexibility of the striking head.

[0016] In one embodiment, the percussion head further includes a fixing bracket for mounting the heating component and an output cap disposed on the fixing bracket. The fixing bracket is provided with a positioning opening, and the output cap covers the positioning opening of the fixing bracket. The second elastic member, the heating sheet, and the heat conduction block are sequentially disposed on the fixing bracket. The heat conduction block is fixed on the positioning opening of the fixing bracket and abuts against the inner wall of the output cap. In this way, by using the positioning opening provided on the fixing bracket to position the heat conduction block, problems such as abnormal changes in the heating temperature caused by the loosening of the heat conduction block or the heating sheet during the percussion movement can be effectively avoided, thereby improving the working stability of the massager.

[0017] In one embodiment, the heat conduction block is provided with an outwardly protruding ring, and the fixing bracket is further provided with a step disposed around the positioning opening. The step is used for buckling with the outwardly protruding ring on the heat conduction block, so as to avoid displacement or loosening that is likely to occur during the movement of the percussion head, and further improve the positioning effect of the heat conduction block.

[0018] The present application also provides a percussion massager, including a housing, a main control part, and the percussion massage mechanism described above. The main control part and the percussion massage mechanism are received in the housing. The percussion massage mechanism is further provided with an output line for electrically connecting with the main control part. A protective sleeve for covering the output line is provided in the housing, and the protective sleeve extends to the connection bridge. The output line extends out of the protective sleeve and is respectively connected into the percussion head through the connection bridge. This makes the layout of the output line inside the massager reasonable and effectively improves the stability of the line connection. In addition, the output line is covered and protected by the protective sleeve to prevent problems such as loosening or abrasion of the output line that are likely to occur after long-term use of the massager, effectively improving the durability and safety of the massager.

[0019] The beneficial effects of the percussion massager and its percussion massage mechanism provided by the present application are as follows: Compared with the prior art, the percussion massager of the present application improves its internal percussion massage mechanism. A first elastic member capable of preventing collision between the driving mechanism and a pair of percussion heads is provided. By utilizing the elastic deformation characteristic of the first elastic member, the first elastic member can undergo elastic deformation when being squeezed, thereby buffering the collision force and effectively playing a sound-absorbing role. It can effectively solve the problem that the movement of the percussion head on a traditional handheld percussion massager is prone to generate collision sounds and cause noise, thereby improving the use experience.

[0043] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0044] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0045] It should be understood that the orientation or positional relationship indicated by the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present application.

[0046] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present application, the meaning of "a plurality" is two or more unless otherwise specifically defined.

[0047] On a traditional handheld percussion massager, the overall volume of the massager is small for convenient handheld use. Each component inside the massager is fitted as compactly as possible. In particular, regarding the spacing between a pair of percussion heads and the drive mechanism, manufacturers generally only reserve the movable space for the percussion heads. However, during the actual production process, the output force of the drive mechanism is prone to deviation. For example, the output power of the drive motor may deviate, and then the transmission structure between the motor and the percussion heads may also have dimensional deviations, making the swing amplitude of a pair of percussion heads uncontrollable. As a result, in some of the produced finished products, a pair of percussion heads inside some products are prone to collide with the drive mechanism during the swing movement. For example, the percussion heads are prone to collide with the outer shell of the motor or the fixed components of the motor, resulting in noise and affecting the user experience.

[0048] Currently, the commonly used solution can only increase the spacing to avoid mutual collision between components. This solution requires increasing the volume of the casing, thus designing a larger casing to further increase the internal margin of the casing to meet the installation requirements of the percussion massage mechanism. It can be seen that this solution sacrifices the overall volume of the machine, resulting in an increase in the overall volume of the machine and affecting the comfort of handheld operation of the massager.

[0049] Herein, an embodiment of the present application provides a new type of handheld percussion massager, which improves the percussion massage mechanism in the massager and effectively solves the problem that the movement of the percussion heads on a traditional handheld percussion massager is prone to collision sounds and generate noise. Now, it will be described in detail.

[0050] Please refer to Figure 1 and Figure 2 together. The percussion massager is provided with the percussion massage mechanism of the present application. The percussion massage mechanism includes a drive mechanism 100, a pair of percussion heads 1, and a first elastic member 2.

[0051] Please refer to Figure 3 , Figure 4 and Figure 5 together. There is a connecting bridge 3 between a pair of percussion heads 1, and a pair of percussion heads 1 are symmetrically connected to both ends of the connecting bridge 3. Preferably, a pair of percussion heads 1 can be integrally connected to both ends of the connecting bridge 3 to ensure the connection strength. A central axis 30 is provided on the connecting bridge 3, so that a pair of percussion heads 1 can swing up and down around the central axis 30 on the connecting bridge 3 like a seesaw.

[0052] The driving mechanism 100 includes a motor 4, a motor base 5, and a connecting rod 6. The connecting rod 6 is connected to the knocking head 1. In this embodiment, the connecting rod 6 can be connected to one of the pair of knocking heads 1. The motor 4 is disposed on the motor base 5, and the motor base 5 needs to be compactly arranged with the above-mentioned pair of knocking heads 1 so that the connecting rod 6 can be smoothly connected to a knocking head 1. If the distance between the motor base 5 and the knocking head 1 is relatively far, it will mean that the length of the connecting rod 6 needs to be increased, resulting in an impact on the transmission stroke.

[0053] The motor 4 is connected to the connecting rod 6 through an eccentric structure. Among them, the eccentric structure 200 can preferably adopt the form of an eccentric wheel to achieve transmission. The eccentric wheel is connected to the connecting rod 6 so that when the motor 4 drives the eccentric wheel to rotate, the connecting rod 6 can be driven to move up and down reciprocally. In this way, the motor 4 drives the connecting rod 6 to drive the pair of knocking heads 1 to swing around the central axis 30 of the connecting bridge 3, realizing the knocking action.

[0054] As Figure 4 and Figure 5 shown, the first elastic member 2 is disposed between the motor base 5 and the connecting bridge 3. The first elastic member 2 is squeezed and deformed by the motor base 5 and the connecting bridge 3 as the pair of knocking heads 1 swing, thereby preventing the connecting bridge 3 from directly contacting the motor base 5 and effectively preventing the two from colliding with each other.

[0055] Compared with the prior art, the knocking massager provided by the embodiment of the present application improves the internal knocking massage mechanism thereof. A first elastic member 2 capable of preventing collision between the driving mechanism 100 and the pair of knocking heads 1 is provided. Utilizing the elastic deformation characteristic of the first elastic member 2, the first elastic member 2 can elastically deform when being squeezed, thereby buffering the collision force and effectively playing a role in noise reduction.

[0056] In addition, since the first elastic member 2 is provided between the driving mechanism 100 and the pair of knocking heads 1, the driving mechanism 100 and the pair of knocking heads 1 can be arranged at a preset installation distance, without increasing the distance between the two in order to prevent mutual collision. The first elastic member 2 provided between the driving mechanism 100 and the pair of knocking heads 1 can directly offset the fitting deviation between the components, thereby improving the compatibility between the components. It can be seen that there is no need to expand the internal volume of the massager, which is beneficial to controlling the volume of the knocking massager, keeping the overall massager light and small, facilitating handheld operation, and improving the user experience.

[0057] Regarding the structure between the motor base 5 and the connecting bridge 3, in one embodiment of the present application, please refer to Figure 6(The central axis 30 in the figure is its shaft hole). An accommodation groove 51 is provided at the upper end of the motor base 5, allowing the motor 4 to be embedded in the accommodation groove 51 for fixation. A connecting plate 52 is provided at the lower end of the motor base 5, and the connecting plate 52 extends onto the connecting bridge 3 between the pair of percussion heads 1. A connecting hole 521 for sleeving with the central axis 30 on the connecting bridge 3 is provided on the connecting plate 52, so that the pair of percussion heads 1 can be compactly arranged with the motor base 5 through the connecting bridge 3.

[0058] In this way, the motor base 5 serves both as a fixing base for the motor 4 for the installation and fixation of the motor 4 and as a mounting base for a pair of percussion heads 1, enabling the pair of percussion heads 1 to be movably arranged on the massager. In a way of making one component serve multiple purposes, the compactness between components is improved, making the whole machine smaller and lighter in volume, and convenient for the user to hold and use.

[0059] Among them, as Figure 6 shown, the motor base 5 is further provided with positioning grooves 53 on both side walls of the above-mentioned accommodation groove 51, and the motor 4 is provided with clamping blocks 41 for clamping into the positioning grooves 53. By the mutual clamping of the clamping blocks 41 and the positioning grooves 53, it is possible to prevent the motor 4 from being easily displaced during operation, effectively improving the fixing effect on the motor 4, and further improving the working stability of the entire driving mechanism 100.

[0060] Regarding the specific structure of the first elastic member 2, it includes but is not limited to the following forms:

[0061] In an embodiment of the present application, please refer to Figure 6 and Figure 7 (The central axis 30 in the figure is its shaft hole). The first elastic member 2 includes a pair of elastic blocks 21, and the elastic blocks 21 are preferably made of soft plastic material, so that the elastic blocks 21 have the characteristic of undergoing telescopic deformation when being squeezed.

[0062] The pair of elastic blocks 21 are respectively arranged on both sides of the central axis 30 of the connecting bridge 3 and abut between the motor base 5 and the connecting bridge 3.

[0063] In this way, when the pair of percussion heads 1 are driven by the driving mechanism 100 to swing, the connecting bridge 3 will swing around the central axis 30 and squeeze the elastic blocks 21 respectively. The elastic blocks 21 are squeezed and undergo telescopic deformation, which can not only play a buffering role but also keep the pair of percussion heads 1 and the driving mechanism 100 in a compact arrangement.

[0064] Regarding the fixing structure of the pair of elastic blocks 21, in this embodiment, please refer to Figure 6 and Figure 7, on the connecting bridge 3, there are fixed grids 31 located on both sides of the central axis 30. On the motor base 5, there is a fixed groove 54, and the position of the fixed groove 54 corresponds to that of the fixed grid 31 on the connecting bridge 3, so that both ends of the elastic block 21 can be respectively embedded in the fixed grid 31 and the fixed groove 54, effectively ensuring the fixing effect on the elastic block 21.

[0065] As an example, such as Figure 6 and Figure 7 shown, the elastic block 21 can preferably be a rectangular strip-shaped elastic plastic. One end of the elastic block 21 is embedded in the fixed groove 54 on the motor base 5, and the other end of the elastic block 21 is embedded in the fixed grid 31 on the connecting bridge 3.

[0066] Furthermore, it can be preferably made that the fixed groove 54, the elastic block 21, and the fixed grid 31 are coaxially aligned, so that the elastic block 21 is vertically arranged between the motor base 5 and the connecting bridge 3 to improve the stability of the telescopic deformation movement of the elastic block 21.

[0067] In this way, both ends of the elastic block 21 are fixed through the fixed groove 54 and the fixed grid 31, effectively preventing the elastic block 21 from being easily displaced during the operation of the striking head 1 and ensuring that the sound insulation effect remains effective.

[0068] In practical applications, the interiors of the above-mentioned fixed groove 54 and fixed grid 31 can preferably be rectangular inner cavity structures, so that both ends of the above-mentioned rectangular strip-shaped elastic block 21 can be respectively embedded in the fixed groove 54 and the fixed grid 31.

[0069] In order to ensure the movement flexibility of the connecting bridge 3, in this embodiment, such as Figure 6 and Figure 7 shown, one end of the elastic block 21 for embedding in the fixed grid 31 can preferably be an arc surface 22, so that one end of the elastic block 21 for embedding in the fixed grid 31 is an arc end.

[0070] In this way, with the swinging movement of the connecting bridge 3, the arc end surface of the elastic block 21 can adaptively change direction on the inner bottom surface of the fixed grid 31. Here, it can be understood that: an arc surface 22 is tangent to a plane, and the arc surface 22 can adaptively change direction, so that the elastic block 21 can adaptively change direction in the fixed grid 31 to match the movement track of the connecting bridge 3, thereby improving the movement flexibility of the connecting bridge 3.

[0071] In another embodiment of the present application (not shown in the figure), the first elastic member 2 can also include a pair of springs (not shown in the figure). The pair of springs are respectively arranged on both sides of the central axis 30 of the connecting bridge 3. One end of the spring is connected to the connecting bridge 3, and the other end of the spring is connected to the motor base 5.

[0072] Specifically, it is preferred to use a pair of springs with the same length and similar elastic strength to make the elasticity of the two springs uniform, so that the knocking force of the pair of knocking heads 1 is uniform, ensuring the massage effect.

[0073] Thus, when the pair of striking heads 1 are driven by the driving mechanism 100 to swing, the connecting bridge 3 swings around the central axis 30 to squeeze the springs. The springs are compressed and deformed, which can not only play a buffering role, but also keep the pair of striking heads 1 and the driving mechanism 100 compact.

[0074] For the specific structure of the striking head 1, please refer to Figure 3 , Figure 8 and Figure 9 A pair of striking heads 1 are each provided with a heating component 7 inside, the heating component 7 includes a second elastic member 71, a heating sheet 72 and a heat-conducting block 73, the heat-conducting block 73 is attached to the output end of the striking head 1, and the second elastic member 71 presses the heating sheet 72 onto the heat-conducting block 73.

[0075] Compared with traditional handheld percussion massagers, traditional massagers with hot compress function set the heating and percussion functions independently. Therefore, during operation, hot compress will be applied first and then massage will be performed. This will cause a significant loss of heat and greatly reduce the massage effect.

[0076] In the percussion massager provided in the embodiment of the present application, a heating component 7 is added to the percussion head 1, so that the percussion head 1 has a hot compress function during the percussion movement. Specifically, the heating sheet 72 is assembled on the percussion head 1, and the heating sheet 72 is tightly attached to the heat conductive block 73 through the second elastic member 71, thereby ensuring the stability of heating; then, the heat conductive block 73 is attached to the output end of the percussion head 1, so that when the percussion head 1 percusses the muscle, the heat emitted by the heating sheet 72 is synchronously transferred to the muscle through the heat conductive block 73, thereby achieving hot compress while massaging, effectively improving the massage effect and body comfort.

[0077] Among them, Figure 3 and Figure 9 As shown, a mica sheet 74 for insulation is provided between the heating sheet 72 and the heat conducting block 73, so that the mica sheet 74 is added as an insulation layer between the heating element and the heat output part. The mica sheet 74 has excellent high temperature resistance and insulation properties, which not only ensures the effective transfer of heat, but also avoids the risk of burns caused by direct high temperature contact with human skin, effectively ensuring the safety of the massager.

[0078] In one embodiment of the present application, please refer to Figure 6 and Figure 9, the connecting rod 6 is connected to one of a pair of percussion heads 1, and one end of the connecting rod 6 is connected to the output end of the motor 4 through an eccentric structure 200.

[0079] Preferably, as Figure 6 shown, the eccentric structure 200 may include an eccentric wheel 201 mounted on the output end of the motor 4. A collar 61 is integrally connected to the end of the connecting rod 6 where it is connected to the eccentric structure 200, and the eccentric wheel 201 is sleeved within the collar 61. In this way, while the motor 4 drives the eccentric wheel 201 to rotate, it will drive the connecting rod 6 to perform a linear movement. Since the connecting rod 6 is connected to the percussion head 1, the rotational movement of the motor 4 is further effectively converted into the percussion action of the percussion head 1.

[0080] In addition, the percussion force and frequency can be precisely controlled by adjusting the length ratio of a pair of percussion heads 1 to meet the usage requirements of different users.

[0081] Among them, as Figure 6 and Figure 9 shown, one end of the second elastic member 71 abuts against the heating element 72, and an elastic ring 75 is provided at the other end of the second elastic member 71. The other end of the connecting rod 6 is sleeved on the elastic ring 75. The elastic ring 75 can preferably be made of soft plastic material so that the elastic ring 75 has good elasticity. A buckle joint 62 is also provided at the other end of the connecting rod 6 away from the collar 61, and the buckle joint 62 is sleeved in the elastic ring 75.

[0082] In this way, by utilizing the elastic deformation characteristics of the elastic ring 75, a flexible connection is achieved between the connecting rod 6 and the percussion head 1, which is beneficial for buffering the swinging movement of a pair of percussion heads 1 and thus improving the movement flexibility of the percussion head 1.

[0083] Preferably, as Figure 6 shown, there is a deflection shaft 63 with a similar conical structure between the collar 61 and the buckle joint 62 of the connecting rod 6, so that the buckle joint 62 can be connected to the central axis of the percussion head 1, thereby improving the adaptability of the connection position between the connecting rod 6 and the percussion head 1.

[0084] Regarding the fixing structure of the heating component 7 inside the percussion head 1, in an embodiment of the present application, please refer to Figure 9 , the percussion head 1 further includes a fixing frame 11 for installing the heating component 7 and an output cap 12. The output cap 12 is used to contact the human skin during the percussion movement of the percussion head 1. The output cap can preferably be an arc-shaped cap, which is beneficial for adapting to different contact angles and thus improving the body feeling effect. The output cap 12 is arranged on the fixing frame 11, and a positioning port 111 is provided on the fixing frame 11. The output cap 12 covers the positioning port 111 of the fixing frame 11.

[0085] Among them, the second elastic member 71, the heating sheet 72, and the heat conduction block 73 are sequentially arranged on the fixing frame 11. Preferably, the second elastic member 71, the heating sheet 72, the mica sheet 74, and the heat conduction block 73 are centered on the fixing frame 11 to balance the weight of the entire striking head 1, thereby improving the working stability of the striking head 1 during the swinging motion.

[0086] As Figure 9 shown, the heat conduction block 73 is fixed on the positioning port 111 of the fixing frame 11 and abuts against the inner wall of the output cap 12. Compared with the traditional structure that uses a special positioning box to fix the heat conduction block 73, the structure is simpler. The positioning port 111 opened on the fixing frame 11 is used to position the heat conduction block 73 so that the heat conduction block 73 is coaxially aligned with the heating sheet 72 and the second elastic member 71, ensuring both the positioning effect and making the entire heat conduction structure more stable, effectively avoiding problems such as abnormal changes in the heating temperature caused by the loosening of the heat conduction block 73 or the heating sheet 72 during the knocking motion, and thus improving the operating stability of the massager.

[0087] Regarding the fixing structure of the above-mentioned heat conduction block 73 on the fixing frame 11, in an embodiment of the present application, please refer to Figure 9 , the heat conduction block 73 is provided with an outward convex ring 731, and the fixing frame 11 is also provided with a step 112 arranged around the positioning port 111. The step 112 is used to engage with the outward convex ring 731 on the heat conduction block 73.

[0088] In this way, the heat conduction block 73 is buckled on the step 112 of the positioning port 111 through the outward convex ring 731 on its outer periphery, thereby avoiding displacement or loosening that is likely to occur during the movement of the striking head 1, and thus improving the positioning effect of the heat conduction block 73.

[0089] Regarding the internal layout of the percussion massager, in an embodiment of the present application, please refer to Figure 10 , the percussion massager further includes a housing 81 and a main control part 82. The main control part 82 and the percussion massage mechanism of the present application are both housed in the housing 81. The main control part 82 may include the main control board and the control panel of the massager. The main control part 82 needs to be electrically connected to the electrical components in the percussion massage mechanism, such as the electrodes of the heating sheet 72. Herein, an output line 83 is also provided on the percussion massage mechanism, and the output line 83 is used to be electrically connected to the main control part 82.

[0090] In practical applications, since the striking head 1 is in motion during the working state of the massager, friction may occur during the movement of the striking head 1, resulting in damage to the cable; or, after the massager has been used for a long time, the output line 83 may be affected by the movement and pulling of the striking head 1, etc., causing these cables to be easily loosened.

[0091] Herein, in an embodiment of the present application, please refer toFigure 9 , a protective sleeve 9 is further provided inside the housing 81. The protective sleeve 9 is preferably a fiber sleeve made of fiber material. The protective sleeve 9 is sleeved on the output wire 83, and the output wire 83 is covered and protected by the protective sleeve 9, so as to prevent the output wire 83 from being prone to problems such as wire routing looseness or wear after long-term use of the massager, effectively improving the durability and safety of the massager.

[0092] Among them, the protective sleeve 9 extends to the connecting bridge 3 between a pair of percussion heads 1. The output wire 83 extends out of the protective sleeve 9 and is respectively connected to the inside of the percussion head 1 through the connecting bridge 3, and is electrically connected to electrical components such as the heating sheet 72 in the percussion head 1.

[0093] Preferably, a wire groove (not shown in the figure) can be formed on the connecting bridge 3, so that the output wire 83 passes through the wire groove after extending out of the protective sleeve 9 and extends into the interiors of the two percussion heads 1 along the wire groove to be electrically connected to the electrical components, thereby improving the protection effect on the output wire 83.

[0094] In this way, the layout of the output wire 83 inside the massager is reasonable and protected, effectively improving the stability of the internal circuit connection of the massager.

[0095] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
