[0035] The following detailed description, in conjunction with the accompanying drawings, further illustrates this utility model. Detailed Implementation

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] In the description of this utility model, it should be noted that the terms "upper," "lower," "left," "right," "horizontal," "vertical," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated.

[0038] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0039] Please combine Figures 1 to 6 This utility model provides a massage mechanism 1000, including a main body and a housing 900 for mounting the main body. The main body includes at least a kneading shaft 1, a percussion shaft 2, a drive motor 3, and two first massage components 100. The kneading shaft 1, percussion shaft 2, drive motor 3, and other components are housed within the housing 900, and the main body has at least one massage head (e.g., a massage head). Figure 1 The first massage head 110 and the second massage head 210 shown protrude from the housing 900. The massage heads are used to massage the massage area. The massage area can be, but is not limited to, the user's neck, shoulders, waist, back, or legs. The massage heads can knead, pound, or perform other massages on the massage area. The specific massage method is related to the movement structure of the massage head, which will be described later.

[0040] like Figure 1 and Figure 2As shown in the embodiment of this utility model, the housing 900 may include a mounting cover 901 and a mounting base 902 that is mated to the mounting cover 901. The mounting cover 901 is not limited to being mated to the mounting base 902 by a detachable means such as a snap-fit ​​connection or a threaded connection, thereby forming an accommodating space between the mounting cover 901 and the mounting base 902 for mounting components such as the kneading shaft 1, the percussion shaft 2, and the drive motor 3. The housing 900 is composed of the detachably mated mounting cover 901 and the mounting base 902, which facilitates disassembly and assembly and is beneficial for quick installation and maintenance of the massage mechanism 1000. The mounting cover 901 and the mounting base 902 are not limited to being made of plastic.

[0041] Preferably, such as Figure 3 and Figure 4 As shown, in an embodiment of this utility model, the housing 900 further includes a gearbox assembly 903 fixedly connected to the mounting cover 901 and / or mounting base 902, the gearbox assembly 903 being located within the aforementioned accommodating space. The gearbox assembly 903 has multiple receiving cavities, and different components such as the drive motor 3 of the main body of the movement and the first transmission mechanism 5 and the second transmission mechanism 6 (described later) can be respectively received and installed in different receiving cavities. For example, the drive motor 3, the first transmission mechanism 5, and the second transmission mechanism 6 are respectively installed in different receiving cavities, or the drive motor 3 is installed in one first receiving cavity, and the first transmission mechanism 5 and the second transmission mechanism 6 are installed in a second receiving cavity. By defining different receiving cavities through the gearbox assembly 903 to install different components separately, not only can the assembly efficiency and assembly accuracy of each component be improved, but also the components can be separated to avoid interference between one component and another component when one component shifts or shakes due to vibration, thereby improving the movement safety of each component. The gearbox assembly 903 can be composed of two or more gearbox shells. The receiving cavity of the gearbox assembly 903 for installing the drive motor 3 is preferably provided with a heat dissipation window or heat dissipation hole, which is not limited or described in detail.

[0042] Preferably, in an embodiment of this invention, the massage mechanism 1000 may further include a bushing 904 made of an elastic material such as silicone (see...). Figure 17 The bushing 904 is located on the side of the housing 900 where the massage head is located (i.e., the side of the mounting base 902 facing away from the mounting cover 901). When the user uses the massage mechanism 1000 for massage, the elastic bushing 904 between the mounting base 902 and the massage area prevents the hard mounting base 902 from causing discomfort to the user. It should be noted that... Figure 2 As shown, the mounting base 902 has a slot 9022 for the massage head to pass through. It is easy to understand that when the massage mechanism 1000 has a bushing 904, the bushing 904 also has a corresponding through hole for the massage head to pass through. This will not be elaborated further.

[0043] Please combine Figure 5 and Figure 6 In this embodiment of the present invention, two first massage components 100 are spaced apart and sleeved on the kneading shaft 1 and located on opposite sides of the drive motor 3 in spatial position. One end of the pounding shaft 2 is connected to one of the two first massage components 100 through an eccentrically arranged connecting part 21, and the other end of the pounding shaft 2 is connected to the other of the two first massage components 100 through another eccentrically arranged connecting part 21. The drive motor 3 has an output shaft 31 at one end and a through hole 32 extending axially along the output shaft 31. The through hole 32 passes through the output shaft 31 and extends through the other end of the drive motor 3 opposite to the output shaft 31. The pounding shaft 2 is rotatably inserted through the through hole 32, and both ends of the pounding shaft 2 are located outside the drive motor 3. It should be noted that, in the embodiments of this utility model, the kneading shaft 1 and the pounding shaft 2 are respectively connected to the output shaft 31 and are configured to drive the two first massage components 100 to move under the action of the output shaft 31, so as to use the first massage head 110 of the first massage component 100 to massage the massage area. As mentioned above, the massage mode of the first massage head 110 is related to its specific motion structure. For example, when only the kneading shaft 1 drives the two first massage components 100 to move under the action of the output shaft 31, the first massage head 110 can perform kneading massage on the massage area. Or, when both the kneading shaft 1 and the percussion shaft 2 drive the two first massage components 100 to move under the action of the output shaft 31, the first massage head 110 can perform percussion massage on the massage area. Or, when only the percussion shaft 2 drives the two first massage components 100 to move under the action of the output shaft 31, the first massage head 110 can also perform percussion massage on the massage area. The percussion frequency of the first massage head 110 is different when the kneading shaft 1 and the percussion shaft 2 drive the two first massage components 100 to move together and when only the percussion shaft 2 drives the two first massage components 100 to move. More detailed information will be described later and will not be repeated here.

[0044] In summary, in the massage mechanism 1000 provided in the embodiments of this utility model, by passing the percussion shaft 2 through the output shaft 31 of the drive motor 3, the massage mechanism 1000 achieves a compact and miniaturized design, making the overall structure of the massage mechanism 1000 compact and small in size. Furthermore, by controlling the output shaft 31 of the drive motor 3 to drive and connect the kneading shaft 1 and / or the percussion shaft 2, the massage mechanism 1000 can use the first massage component 100 to perform kneading massage or percussion massage on the massage area as needed, which helps to improve the massage effect and has a better effect on relieving fatigue and discomfort in the massage area.

[0045] Preferably, in Figures 1 to 6In the example, the main body of the massage mechanism 1000 may further include two second massage components 200. The two second massage components 200 are spaced apart and sleeved on the kneading shaft 1, located outside the two first massage components 100. The kneading shaft 1 is configured to drive both the two first massage components 100 and the two second massage components 200 simultaneously. In this embodiment, by sleeved two second massage components 200 on the kneading shaft 1, the first massage components 100 and the second massage components 200 can massage different massage areas or different areas of the same massage area, increasing the massage range of the massage mechanism 1000. Furthermore, by setting two second massage components 200, on the one hand, the kneading shaft 1 can drive the two second massage components 200 to perform bilateral kneading massage on the user, which helps improve the massage effect; on the other hand, it makes the overall structure of the massage mechanism 1000 symmetrical, thereby improving the overall aesthetics and stability of the massage mechanism 1000 during operation. Of course, in other embodiments of this utility model, the massage mechanism 1000 may also have only one second massage component 200 on the outside of the two first massage components 100, and there is no limitation on this.

[0046] It is understood that in the embodiments of this utility model, the first massage component 100 and the second massage component 200 can adopt different structural designs and be connected to the kneading shaft 1, and the pounding shaft 2 can also adopt different structural designs and be connected to the two first massage components 100. The following will refer to the accompanying drawings. Figure 1 To be continued Figure 23 The following is a further detailed description of the massage mechanism 1000 provided in the embodiments of this utility model.

[0047] For specific details, please refer to... Figure 5 and Figure 6 In the first embodiment of this utility model, the main body of the massage mechanism 1000 further includes a transmission sleeve 4, a first transmission mechanism 5, and a second transmission mechanism 6. The transmission sleeve 4 is fixedly sleeved on the outer peripheral wall of the output shaft 31 and coaxially arranged with the output shaft 31. The transmission sleeve 4 is provided with a first connecting portion and a second connecting portion distributed axially. The first transmission mechanism 5 is drivingly connected between the first connecting portion and the kneading rotating shaft 1, and the second transmission mechanism 6 is drivingly connected between the second connecting portion and the pounding rotating shaft 2. In this embodiment, the output shaft 31 is drivingly connected to the kneading rotating shaft 1 and the pounding rotating shaft 2 respectively through the first transmission mechanism 5, the second transmission mechanism 6, and the transmission sleeve 4 with different connecting portions. The output shaft 31 does not require special design; it only needs to have a through hole 32 to accommodate the pounding rotating shaft 2. The structure of the output shaft 31 is simple and easy to manufacture, which helps reduce the difficulty of selecting the drive motor 3. Furthermore, the transmission sleeve 4 sleeved outside the output shaft 31 can be flexibly designed as needed and is easy to disassemble and maintain.

[0048] Optionally, in Figure 5 and Figure 6 In the example, the transmission sleeve 4 is fitted onto at least a portion of the outer peripheral wall of the hammering shaft 2, which is located outside the output shaft 31. In this embodiment, fitting the transmission sleeve 4 onto at least a portion of the outer peripheral wall of the hammering shaft 2 not only protects and limits the hammering shaft 2, improving its rotational smoothness, but also allows the hammering shaft 2 to support the transmission sleeve 4. This reduces the axial length of the output shaft 31, thus lowering its manufacturing difficulty.

[0049] Alternatively, in Figure 5 and Figure 6 In the example, the first transmission mechanism 5 and / or the second transmission mechanism 6 are not limited to a transmission mechanism including a double worm gear assembly, a transmission mechanism including a worm gear assembly and a gear transmission assembly, or a transmission mechanism including a double pulley assembly. In other words, in this embodiment, the first transmission mechanism 5 and the second transmission mechanism 6 can each adopt more than one design scheme, as long as the first transmission mechanism 5 can be driven to connect between the first connecting part of the kneading shaft 1 and the transmission sleeve shaft 4, and the second transmission mechanism 6 can be driven to connect between the second connecting part of the pounding shaft 2 and the transmission sleeve shaft 4.

[0050] For more specific details, please refer to... Figures 5 to 8In one embodiment of this utility model, the transmission sleeve shaft 4 is a generally tubular shaft. The outer peripheral wall of the transmission sleeve shaft 4 is provided with an axially arranged meshing connection portion 41 and a pulley connection portion 42. The meshing connection portion 41 is located on the outer peripheral wall of the transmission sleeve shaft 4 at the end near the output shaft 31, and the meshing connection portion 41 consists of multiple spiral first meshing teeth. The portion of the transmission sleeve shaft 4 with the meshing connection portion 41 constitutes a first worm gear. The pulley connection portion 42 is located on the outer peripheral wall of the transmission sleeve shaft 4 at the end away from the output shaft 31, and the pulley connection portion... 42 is a pulley structure with a belt groove. The portion of the transmission sleeve shaft 4 with the pulley connection part 42 constitutes the first driving pulley. The first transmission mechanism 5 includes a first worm gear 51, a second worm 52, and a second worm gear 53. One end of the second worm 52 is a smooth rod, and the other end of the second worm 52 is a rod with multiple spiral second meshing teeth. The first worm gear 51 is coaxially fixedly sleeved on the smooth rod of the second worm 52 and meshes with the aforementioned first worm. The second worm gear 53 is coaxially fixedly sleeved on the kneading shaft 1 and meshes with the first worm. The second worm gear 52, with its second meshing teeth, meshes with each other. Thus, the output shaft 31 can be connected to the kneading shaft 1 via the meshing connection 41 of the transmission sleeve shaft 4 and the first transmission mechanism 5, which employs a double worm gear transmission principle. The second transmission mechanism 6 includes a first synchronous belt 63, a first driven pulley 64, a second driving pulley 65, a second synchronous belt 66, and a second driven pulley 67. The first driven pulley 64 and the second driving pulley 65 are coaxially and rotatably mounted on the kneading shaft 1. 5. The second driven wheel 67 is coaxially sleeved on the shaft body of the hammering shaft 2 located outside the transmission sleeve shaft 4. The first synchronous belt 63 synchronously connects the aforementioned first driving wheel and first driven wheel 64. The second synchronous belt 66 synchronously connects the second driving wheel 65 and the second driven wheel 67. Thus, when the second driven wheel 67 is driven and connected to the hammering shaft 2, the output shaft 31 can be driven and connected to the hammering shaft 2 through the pulley connection part 42 of the transmission sleeve shaft 4 and the second transmission mechanism 6 which adopts the double belt pulley transmission principle. In this embodiment, the meshing connection part 41 and the pulley connection part 42 of the transmission sleeve shaft 4 constitute the aforementioned first connection part and second connection part, respectively. The two connection parts have simple structures and are easy to manufacture. The first transmission mechanism 5 is a double worm gear transmission mechanism and the second transmission mechanism 6 is a double belt pulley transmission mechanism. Both can reduce the speed and increase the torque of the driving force provided by the output shaft 31. This avoids the kneading shaft 1 from having a poor kneading massage effect due to its high speed and low torque, and also avoids the percussion shaft 2 from having an excessively high percussion massage frequency in the first massage component 100 due to its high speed, which would cause discomfort to the user. Furthermore, the components of the first transmission mechanism 5 and the second transmission mechanism 6 are designed in a compact manner, which helps to reduce the size of the massage core 1000.

[0051] It should be noted that, in Figures 5 to 8In the example, the transmission sleeve 4 can be coaxially fixed to the end of the output shaft 31 by any means such as snap-fit ​​connection, welding or interference fit connection. Then, the hammering shaft 2 is inserted into the transmission sleeve 4 and the output shaft 31. This is not limited or described in detail. Furthermore, the second worm 52, which is fitted with the first worm wheel 51, can be rotatably installed in the housing 900 at both ends of the axial direction by bearings. Specifically, it can be installed in the gearbox assembly 903. The second worm wheel 53 can be detachably fixed to the kneading shaft 1 by pins or other means. The first driven wheel 64 and the second driving wheel 65 can be rotatably fitted to the kneading shaft 1 by bearings and fixed along the axial direction of the kneading shaft 1 by a snap ring or a stop ring or other stop structure. This is not limited or described in detail.

[0052] It is understood that in other embodiments of this utility model, the massage mechanism 1000 can also directly provide a first connecting part and a second connecting part distributed along the axial direction of the output shaft 31 on the outer peripheral wall of the output shaft 31. Similarly, the first transmission mechanism 5 can be driven between the first connecting part and the kneading shaft 1, and the second transmission mechanism 6 can be driven between the second connecting part and the percussion shaft 2. Thus, there is no need to additionally provide a transmission sleeve shaft 4, simplifying the structure and installation steps of the massage mechanism 1000. It is also understood that in other embodiments of this utility model, the first transmission mechanism 5 and the second transmission mechanism 6 can also adopt other forms of transmission mechanisms, such as the first transmission mechanism 5 using a belt pulley transmission mechanism and the second transmission mechanism 6 using a worm gear transmission mechanism. This is not limited or elaborated upon.

[0053] Preferably, in Figures 5 to 8In the example, the first transmission mechanism 5 is configured to always enable the transmission connection between the output shaft 31 and the kneading shaft 1, so that the kneading shaft 1 can be driven to rotate whenever the output shaft 31 rotates, thereby enabling the kneading shaft 1 to drive the two first massage components 100 to move. The second transmission mechanism 6 is configured to enable the transmission connection between the output shaft 31 and the percussion shaft 2 only when the output shaft 31 rotates in a preset direction, so that the output shaft 31 and the percussion shaft 2 can be engaged or disengaged as needed. Specifically, in this embodiment, in response to the output shaft 31 rotating in the first direction, the output shaft 31 is connected to the percussion shaft 2 via the second connecting part and the second transmission mechanism 6. The output shaft 31 and the percussion shaft 2 are engaged, so that the percussion shaft 2 can drive the two first massage components 100 to swing around the kneading shaft 1. In this way, the two first massage components 100 will move under the dual driving action of the kneading shaft 1 and the percussion shaft 2 to achieve percussion massage. In response to the output shaft 31 rotating in the second direction (opposite to the first direction), the transmission connection between the percussion shaft 2 and the output shaft 31 is separated. At this time, the two first massage components 100 will only move under the sole driving action of the kneading shaft 1 to achieve kneading massage. In other words, in this embodiment, the user can adjust the massage mode of the two first massage components 100 by controlling the rotation direction of the output shaft 31 of the drive motor 3. For example, controlling the output shaft 31 to rotate forward (along the first direction) can achieve percussion massage, and controlling the output shaft 31 to rotate in reverse (along the second direction) can achieve kneading massage, thereby meeting the user's different massage needs. How the kneading shaft 1 drives the movement of the two first massage components 100, and how the percussion shaft 2 drives the movement of the two first massage components 100, will be described in detail later.

[0054] For details, please refer to Figure 6In the first embodiment of this utility model, in order to enable the output shaft 31 and the hammering shaft 2 to be engaged or disengaged as needed, the second transmission mechanism 6 further includes a control member 61. The transmission assembly consisting of the aforementioned first synchronous belt 63, first driven pulley 64, second driving pulley 65, second synchronous belt 66, and second driven pulley 67 is defined as the first transmission assembly 62. The control member 61 is disposed between the first transmission assembly 62 and the hammering shaft 2. Specifically, in response to the output shaft 31 rotating in a first direction, the control member 61 is in a first state, and the output shaft 31 is connected to the hammering shaft 2 via the second connecting part, the control member 61, and the first transmission assembly 62; in response to the output shaft 31 rotating in a second direction, the control member 61 is in a second state, and the transmission connection between the hammering shaft 2 and the output shaft 31 is disengaged. In this embodiment, by setting a control component 61 between the hammering shaft 2 and the first transmission component 62, which can switch the working state according to the change of the rotation direction of the output shaft 31, the output shaft 31 can be controlled to engage or disengage from the hammering shaft 2. The overall solution is simple and will not cause the volume of the second transmission mechanism 6 to increase significantly.

[0055] Optionally, in Figure 6 In the example, the control component 61 uses a one-way bearing. The inner ring of the one-way bearing is fixedly sleeved on the hammering shaft 2. The second driven wheel 67 included in the first transmission assembly 62 is fixedly sleeved on the outer ring of the one-way bearing. It can be understood that, due to the characteristics of the one-way bearing, when the output shaft 31 drives the second driven wheel 67 to rotate in the first direction through the second connecting part of the transmission sleeve shaft 4 (i.e., the aforementioned pulley connecting part 42), the second driven wheel 67 drives the outer and inner rings of the one-way bearing to rotate in the first direction (the one-way bearing is in the first state). The inner ring of the one-way bearing then drives the hammering shaft 2 to rotate, thereby causing the output shaft 31 to rotate through the control component 61 and the first transmission assembly 62. When engaged with the percussion shaft 2, the percussion shaft 2 can drive the two first massage components 100 to swing around the axis of the kneading shaft 1. Conversely, when the output shaft 31 drives the second driven wheel 67 to rotate in the second direction through the second connecting part, the second driven wheel 67 drives the outer ring of the one-way bearing to rotate but cannot drive the inner ring of the one-way bearing to rotate (the one-way bearing is in the second state). The inner ring of the one-way bearing cannot drive the percussion shaft 2 to rotate, so that the output shaft 31 is separated from the percussion shaft 2 through the control component 61 and the first transmission component 62. The percussion shaft 2 cannot drive the two first massage components 100 to swing around the axis of the kneading shaft 1.

[0056] Alternatively, in other embodiments of this utility model, the control element 61 may also take the form of a single component or a combination of multiple components, such as, but not limited to, the control element 61 adopting a spring assembly, which includes a spring, a clutch sleeve, and a fixed sleeve. The spring is at least partially sleeved on the fixed sleeve, and the fixed sleeve is fixedly sleeved on the hammering shaft 2. The clutch sleeve is rotatably sleeved on the hammering shaft 2. The end of the spring near the clutch sleeve is fixedly connected to the clutch sleeve, and the second driven wheel 67 is fixedly sleeved on the outer peripheral wall of the clutch sleeve. The clutch sleeve can rotate in different directions under the drive of the second driven wheel 67 driven by the output shaft 31. When the clutch sleeve drives the retaining spring to rotate in the direction of spring tightening, the retaining spring can clamp the fixed sleeve (the retaining spring assembly is in the first state), thereby driving the fixed sleeve and the hammering shaft 2 to rotate. Conversely, when the clutch sleeve drives the retaining spring to rotate in the opposite direction to the direction of spring tightening, the retaining spring can loosen from the fixed sleeve and be fitted onto the fixed sleeve with a gap (the retaining spring assembly is in the second state), and the retaining spring cannot drive the fixed sleeve and the hammering shaft 2 to rotate. The fixed sleeve can be fixedly fitted onto the hammering shaft 2 by a pin or a flat limiting part, and there is no limitation on this.

[0057] It is understood that in other embodiments of this utility model, the second transmission mechanism 6 may not be equipped with the control element 61, so that the output shaft 31 can be engaged with the hammering shaft 2 through the second connecting part of the transmission sleeve shaft 4 and the second transmission mechanism 6, regardless of whether the output shaft 31 rotates forward or backward. This allows the output shaft 31 to rotate the hammering shaft 2, thereby driving the two first massage components 100 to swing around the axis of the kneading shaft 1. At the same time, the kneading shaft 1 can always drive the two first massage components 100 to move. Therefore, the two first massage components 100 will perform hammering massage under the dual driving action of the kneading shaft 1 and the hammering shaft 2. That is, when the second transmission mechanism 6 is not equipped with the control element 61, the two first massage components 100 will only perform hammering massage regardless of whether the output shaft 31 rotates forward or backward.

[0058] In embodiments of this utility model, the hammering shaft 2 is connected to the first massage assembly 100 via a connecting portion 21 at its end, which can be achieved through various methods. Specifically, please refer to... Figures 6 to 10In one embodiment of this utility model, the connecting part 21 located at the shaft end of the hammering shaft 2 is an eccentric column extending along the axial direction of the hammering shaft 2, and the axis of the eccentric column does not coincide with the rotation axis of the hammering shaft 2. The two connecting parts 21 located at opposite ends of the hammering shaft 2 are symmetrical about the axis of the hammering shaft 2. The massage mechanism 1000 also includes two second transmission components 22. The second transmission component 22 includes a first connecting arm 221 and a first adapter 222. One end of the first connecting arm 221 is provided with a ball head 2211 and is hinged to the first massage component 100 (specifically the connecting rod 120 mentioned later) through the ball head 2211. The first adapter 222 is rotatably sleeved on the connecting part 21 of the hammering shaft 2, and the first adapter 222 is rotatably connected to the other end of the first connecting arm 221. The rotation axis of the first connecting arm 221 relative to the first adapter 222 is perpendicular to the hammering shaft 2. In this embodiment, the connecting part 21 at the end of the hammering shaft 2 adopts an eccentric column structure and is connected to the first massage assembly 100 via a second transmission assembly 22 composed of a first connecting arm 221 and a first adapter 222. The overall design and the structure of each component are very simple and easy to assemble and disassemble. Of course, in other embodiments of this utility model, the connecting part 21 may also adopt other structures, such as, but not limited to, a bushing eccentrically fitted onto the end of the hammering shaft 2, which will not be elaborated further.

[0059] like Figure 9 and Figure 10 As shown, in this embodiment, the first connecting arm 221 specifically includes a cylinder 2212 and a U-shaped connecting block 2213. A ball head 2211 is disposed at one axial end of the cylinder 2212, and the U-shaped connecting block 2213 is disposed at the other axial end of the cylinder 2212. The space between the two plate-like structures of the U-shaped connecting block 2213 is used to accommodate the first adapter 222. The U-shaped connecting block 2213 and the first adapter 222 are respectively provided with through holes for inserting a rotating shaft, so that the first adapter 222 and the U-shaped connecting block 2213 at one end of the first connecting arm 221 are rotatably connected through a rotating shaft. The ball head 2211 and the cylinder 2212 can be detachably connected by means of threaded connection or other means. The ball head 2211 is disposed in the hinge hole 1201 (described later) of the connecting rod 120, thereby realizing that the first connecting arm 221 is hinged to the first massage assembly 100 through the ball head 2211. The first adapter 222 also has a section along the eccentric post (i.e. Figure 8The connecting part 21) has an axially extending sleeve hole through which the first adapter 222 is rotatably fitted onto the eccentric column at the shaft end of the hammering shaft 2. It can be understood that one end of the first adapter 222 abuts against the stop step formed at the connection between the eccentric column and the hammering shaft 2. The end of the eccentric column away from the hammering shaft 2 can be provided with a retaining spring or other components to stop the other end of the first adapter 222. Gaskets can be provided at the opposite ends of the first adapter 222 to reduce the friction between the first adapter 222 and the stop step and the friction between the first adapter 222 and the retaining spring.

[0060] The first adapter 222 is not limited to a wedge-shaped block connector or a square block connector. It can be rotatably fitted onto the connecting part 21 (i.e., the eccentric column) and rotatably connected to one end of the first connecting arm 221. No limitation or elaboration is made in this regard.

[0061] It is understood that in other embodiments of this utility model, the connecting part 21 may also be hinged to the first massage component 100 in other ways. For example, but not limited to, the end of the connecting part 21 away from the hammering shaft 2 may be directly fitted with a universal ball head, and the end of the cylinder 2212 near the connecting part 21 may be directly hinged to the universal ball head, thereby eliminating the need for the U-shaped connecting block 2213. Alternatively, the second transmission component 22 may adopt a double connecting arm and achieve the transmission connection between the connecting part 21 and the first massage component 100 by means of double-axis staggered hinge. This is not limited or elaborated.

[0062] Please combine again Figures 6 to 10 In the first embodiment of this utility model, the first massage component 100 includes a first massage head 110 and a connecting rod 120, and each first massage component 100 is eccentrically mounted on the kneading shaft 1 via a first mounting component 130. The first massage head 110 is disposed at one end of the connecting rod 120, and the first mounting component 130 is disposed at the other end of the connecting rod 120. The first mounting component 130 is eccentrically mounted on the kneading shaft 1 so that the rotation of the kneading shaft 1 can drive the first massage component 100 to move, thereby enabling the first massage head 110 to perform kneading or percussion massage on the massage area.

[0063] Specifically, in Figures 6 to 10In the example, the connecting rod 120 includes a rocker arm 1202 and a first collar 1203. The first massage head 110 is disposed at one end of the rocker arm 1202, and the first collar 1203 is disposed at the other end of the rocker arm 1202. The outer peripheral wall of the first collar 1203 near the second transmission component 22 is provided with a protrusion structure 1204. The protrusion structure 1204 has the aforementioned hinge hole 1201, and the protrusion structure 1204 has a notch 1205 communicating with the hinge hole 1201 on the side facing the second transmission component 22. The end of the cylinder 2212 of the first connecting arm 221 away from the first adapter 222 passes through the notch 1205 into the hinge hole 1201 and is detachably connected to the ball head 2211 disposed in the hinge hole 1201, thereby realizing that the second transmission component 22 is hinged to the first massage component 100 through the ball head 2211. The notch 1205 provides space for the second transmission component 22 to move around the kneading shaft 100 when it is driven by the hammering shaft 2. The opening of the hinge hole 1201 can be closed by the cover 1206, which will not be described in detail.

[0064] exist Figures 6 to 10In the example, the first mounting assembly 130 includes a first deflector 131 and a second end cap 132. The first deflector 131 includes a first cylindrical assembly 1311 and a first end cap 1312. The first end cap 1312 is connected to one side of the first cylindrical assembly 1311. The first collar 1203 of the connecting rod 120 is rotatably sleeved on the circumferential surface of the first cylindrical assembly 1311. The second end cap 132 is detachably connected to the other side of the first cylindrical assembly 1311, such that the opposite sides of the first collar 1203 are respectively limited by the first end cap 1312 and the second end cap 132. It should be noted that in this embodiment, the first deflection seat 131 and the second end cap 132 are provided with through holes, and the axis of the through holes is parallel and spaced apart from the axis of the kneading shaft 1. The first deflection seat 131 and the second end cap 132 are eccentrically fitted onto the kneading shaft 1 through the through holes, so that the first massage component 100 is eccentrically fitted onto the kneading shaft 1 through the first mounting component 130. The axis of the first cylindrical assembly 1311 and the axis of the kneading shaft 1 are located in the same plane but have an included angle. Furthermore, a first limiting mechanism is provided between the first mounting component 130 and the kneading shaft 1, which is used to limit the first mounting component 130 and the kneading shaft 1 to remain relatively fixed along the circumference of the kneading shaft 1. It is easy to understand that in this embodiment, when the hammering shaft 2 rotates under the action of the output shaft 31, the connecting part 21 (i.e., the eccentric column) at the shaft end of the hammering shaft 2 will drive the connecting rod 120 and the first massage head 110 of the first massage component 100 to swing around the axis of the first cylindrical assembly 1311 through the second transmission component 22, that is, to swing around the kneading shaft 1; when the kneading shaft 1 rotates under the drive of the output shaft 31, the kneading shaft 1 can drive the first deflection seat 131 and the second end cover 132 to rotate around the axis of the kneading shaft 1. The first cylindrical assembly 1311 of the first deflection seat 131 converts the rotational motion of the kneading shaft 1 into the swaying motion of the connecting rod 120 and the first massage head 110. The swaying trajectory is a figure-eight shaped trajectory that is horizontally placed along the axial direction of the kneading shaft 1. It can be understood that when the first massage component 100 moves only under the driving action of the kneading shaft 1, the movement trajectory of the first massage head 110 is a swaying motion, thereby realizing the kneading massage of the massage area; conversely, when the first massage component 100 moves under the dual driving action of the kneading shaft 1 and the percussion shaft 2, the movement trajectory of the first massage head 110 is a composite motion trajectory of swaying motion and swinging motion. However, since the frequency of the percussion shaft 2 driving the first massage component 100 to swing around the kneading shaft 1 is greater than the swinging frequency generated by the kneading shaft 1 driving the first massage component 100 to swing around the kneading shaft 1, the first massage component 100 can realize the percussion massage of the massage area.

[0065] Of course, in other embodiments of this utility model, the axis of the first cylindrical assembly 1311 and the axis of the kneading shaft 1 can also be arranged parallel and spaced apart. When the first cylindrical assembly 1311 converts the rotational motion of the kneading shaft 1 into the swaying motion of the connecting rod 120 and the first massage head 110, the swaying trajectory is a "1" shaped trajectory along the direction perpendicular to the kneading shaft 1, that is, swinging up and down. This will not be elaborated further.

[0066] Optionally, in Figures 6 to 10 In the example, the first limiting mechanism between the first mounting component 130 and the kneading shaft 1 includes a first flat limiting portion 11 and a first mounting hole adapted to the first flat limiting portion 11. The first flat limiting portion 11 is disposed on the outer peripheral wall of the portion of the kneading shaft 1 used to fit the first mounting component 130. The first mounting component 130 also includes a first assembly block 133 with a first mounting hole for passing through the first flat limiting portion 11. At least a portion of the first assembly block 133 passes through the mounting holes of the first deflection seat 131 and the second end cap 132, and the first assembly block 133 is detachably connected to the first deflection seat 131 and / or the second end cap 132. For example, the first assembly block 133 is embedded in the side of the first deflection seat 131 away from the second end cap 132 and is fixedly connected to the first deflection seat 131, so that the kneading shaft 1 and the first mounting component 130 are relatively fixed along the circumference of the kneading shaft 1. When the kneading shaft 1 rotates under the drive of the output shaft 31, the first flat limiting part 11 ensures that the rotating kneading shaft 1 drives the first deflection seat 131 and the second end cap 132 to rotate, thereby driving the first massage component 100 to move to achieve a massage operation. The outer peripheral wall of the portion of the kneading shaft 1 used to fit the first massage component 100 can be formed by removing part of the material to create the first flat limiting part 11. In this embodiment, the detachable connection between the first deflection seat 131 and the second end cap 132, and the detachable connection between the first assembly block 133 and the first deflection seat 131 and / or the second end cap 132, can be, but is not limited to, threaded connections or snap-fit ​​connections; these are not limited or described in detail.

[0067] Of course, in other embodiments of this utility model, the first mounting component 130 may not have the first assembly block 133, and the through holes of the first deflection seat 131 and the second end cap 132 may be designed to fit the first flat limiting part 11, so that the first deflection seat 131 and the second end cap 132 are sleeved on the first flat limiting part 11, and the kneading shaft 1 and the first mounting component 130 may be fixed relative to each other along the circumference of the kneading shaft 1.

[0068] It is understood that in the embodiments of this utility model, the specific structure of each component of the first mounting component 130 can have various designs, as long as the first massage component 100 can be eccentrically mounted on the kneading shaft 1, which will not be elaborated further.

[0069] Preferably, please combine Figures 11 to 13 In the first embodiment of this utility model, the first massage head 110 includes a first housing 111 and a second housing 112 detachably connected to the first housing 111. The first housing 111 is connected to one end of the connecting rod 120 (i.e., the end of the rocker arm 1202 away from the first collar 1203). The second housing 112 is configured to contact the massage area when the first massage assembly 100 moves. The engagement direction of the first housing 111 and the second housing 112 is perpendicular or approximately perpendicular to the massage area, and the second housing 112 can move relative to the first housing 111 along the engagement direction. In this embodiment, the first massage head 110 is composed of the engagement of the first housing 111 and the second housing 112, and the second housing 112 can move relative to the first housing 111 along the engagement direction. This allows adjustment of the massage intensity when the first massage head 110 massages the massage area through the second housing 112, thereby meeting the needs of different users for different massage intensities.

[0070] The first housing 111 and the rocker arm 1202 of the connecting rod 120 are integral structures or detachably connected, preferably integral structures; the first housing 111 and the second housing 112 are preferably detachably coupled by a threaded connection, which not only allows for stepless adjustment of the relative movement distance between the two housings to better adapt to the massage intensity needs of different users, but also the threaded connection has self-locking properties, which can ensure that the two housings will not easily move relative to each other again without human intervention, thereby ensuring that the adjusted massage intensity is relatively stable.

[0071] Specifically, such as Figures 11 to 13 As shown, in the first embodiment of this utility model, the first housing 111 includes a first ring post 1112, the inner peripheral wall of the first ring post 1112 is provided with a first thread, and the second housing 112 includes a second ring post 1122, the outer peripheral wall of the second ring post 1122 is provided with a second thread, the second ring post 1122 is configured to be received in the first ring post 1112, and the first thread and the second thread are adapted to make the first housing 111 and the second housing 112 threadedly connected. In this embodiment, the first housing 111 and the second housing 112 are directly threadedly connected, and the relative movement distance between the first housing 111 and the second housing 112 is adjusted by rotating the second housing 112. The first massage head 110 has a simple structure and is easy to operate.

[0072] In other embodiments of this utility model, the first housing 111 and the second housing 112 can also be connected by a transition piece, such as a double-ended nut. One end of the double-ended nut is fixedly connected to the second housing 112 and the other end is threadedly connected to the first housing 111. The two nuts of the double-ended nut are located between the two housings. The relative movement between the two housings can be achieved by turning one of the nuts. This will not be elaborated further.

[0073] Furthermore, in Figures 11 to 13 In the example, the first housing 111 further includes a first connecting post 1114 disposed inside the first annular post 1112. The first connecting post 1114 is configured to be received in the second annular post 1122. The outer peripheral wall of the first connecting post 1114 is provided with a first limiting structure 1115, and the inner peripheral wall of the second annular post 1122 is provided with a second limiting structure 1125. The first limiting structure 1115 and the second limiting structure 1125 cooperate to prevent the second housing 112 from rotating relative to the first housing 111 when not subjected to a force along the circumferential direction of the second annular post 1122. It can be understood that by setting mutually cooperating limiting structures, ensuring that the second housing 112 is fixed relative to the first housing 111 when not subjected to rotational force is beneficial to ensuring that the massage intensity of the first massage head 110 remains unchanged after adjustment. Preferably, in this embodiment, the first connecting post 1114 is a cylindrical body, and the second housing 112 further includes a positioning post 1124 located within the second annular post 1122. The positioning post 1124 is configured to be accommodated and inserted into the inner cavity of the first connecting post 1114, and a threaded hole is provided at the end of the positioning post 1124. The first housing 111 has a through hole corresponding to the positioning post 1124. A screw is threaded through the through hole and screwed into the threaded hole at the end of the positioning post 1124, which helps to improve the connection reliability between the first housing 111 and the second housing 112. It should be noted that the pitch of the threaded hole at the end of the positioning post 1124 is the same as the pitch corresponding to the threaded connection between the first housing 111 and the second housing 112, thereby ensuring that the second housing 112 can be rotated normally to move relative to the first housing 111.

[0074] Optionally, a positioning member is inserted into the outer peripheral wall of the first connecting post 1114. A ball head is provided at one end of the positioning member near the second annular post 1122, and at least a portion of the ball head protrudes from the outer peripheral wall of the first connecting post 1114. The portion of the ball head protruding from the outer peripheral wall of the first connecting post 1114 constitutes a first limiting structure 1115. Multiple strip grooves are provided circumferentially on the inner peripheral wall of the second annular post 1122. The cross-sectional shape of each strip groove matches the contour of the ball head, and each strip groove extends axially along the second annular post 1122. The multiple strip grooves constitute a second limiting structure 1125. In this embodiment, the first limiting structure 1115 and the second limiting structure 1125 respectively employ a positioning member with a ball head and multiple strip grooves with cross-sectional shapes matching the contour of the ball head, resulting in a simple structure that is easy to manufacture.

[0075] In other embodiments of this utility model, the first limiting structure 1115 and the second limiting structure 1125 may adopt other structural forms, such as, but not limited to, a positioning member with a ball head inserted into the inner peripheral wall of the second ring column 1122 to form the second limiting structure 1125, and multiple strip grooves disposed on the outer peripheral wall of the first connecting column 1114 to form the first limiting structure 1115. These will not be elaborated or limited.

[0076] Of course, in other embodiments of this utility model, the first housing 111 and the second housing 112 can also be detachably coupled in other ways, for example, but not limited to, one of the first housing 111 and the second housing 112 is provided with a plurality of first positioning holes at intervals along the coupling direction, and the other of the first housing 111 and the second housing 112 is provided with only one second positioning hole. By inserting a positioning pin into the second positioning hole and different first positioning holes, the relative movement distance between the two housings can also be adjusted, thereby adjusting the massage intensity of the first massage head 110.

[0077] Please combine Figure 6 , Figures 14 to 16 In the first embodiment of this utility model, the second massage component 200 includes a second massage head 210 and a second connecting arm 220, and each second massage component 200 is sleeved on the kneading shaft 1 via a second mounting component 230. The second massage head 210 is disposed at one end of the second connecting arm 220, and the second mounting component 230 is disposed at the other end of the second connecting arm 220. The second mounting component 230 is sleeved on the kneading shaft 1 so that the rotation of the kneading shaft 1 can drive the second massage component 200 to move, thereby causing the second massage head 210 to knead and massage the massage area.

[0078] Specifically, in Figure 6 , Figures 14 to 16In the example, the second massage head 210 is disposed at one end of the second connecting arm 220, and the other end of the second connecting arm 220 is provided with a second collar 2202. The second mounting assembly 230 includes a second deflection seat 231 and a fourth end cap 232. The second deflection seat 231 includes a second cylindrical assembly portion 2311 and a third end cap 2312. The third end cap 2312 is connected to one side of the second cylindrical assembly portion 2311. The second collar 2202 is rotatably sleeved on the circumferential surface of the second cylindrical assembly portion 2311. The fourth end cap 232 is detachably connected to the other side of the second cylindrical assembly portion 2311, so that the opposite sides of the second collar 2202 are respectively limited by the third end cap 2312 and the fourth end cap 232. It should be noted that in this embodiment, the second deflection seat 231 and the fourth end cap 232 are provided with through holes, and the axis of the through holes coincides with the axis of the kneading shaft 1. The second deflection seat 231 and the fourth end cap 232 are coaxially sleeved on the kneading shaft 1 through the through holes, so that the second massage component 200 is sleeved on the kneading shaft 1 through the second mounting component 230. As is the case with the first cylindrical assembly 1311 mentioned above, the axis of the second cylindrical assembly 2311 and the axis of the kneading shaft 1 are located on the same plane but have an included angle between them. Furthermore, there is a second limiting mechanism between the second mounting component 230 and the kneading shaft 1. The second limiting mechanism is used to limit the second mounting component 230 and the kneading shaft 1 to remain relatively fixed along the circumference of the kneading shaft 1. It is easy to understand that in this embodiment, when the kneading shaft 1 rotates under the drive of the output shaft 31, the kneading shaft 1 can drive the second deflection seat 231 and the fourth end cover 232 to rotate around the axis of the kneading shaft 1. The second cylindrical assembly part 2311 of the second deflection seat 231 converts the rotational motion of the kneading shaft 1 into the swaying motion of the second connecting arm 220 and the second massage head 210. The swaying trajectory is a figure-eight trajectory that is horizontally placed along the axial direction of the kneading shaft 1, so that the second massage component 200 can knead and massage the massage area through the swaying motion of the second massage head 210.

[0079] Optionally, in Figure 6 , Figures 14 to 16 In the example, the second limiting mechanism between the second mounting component 230 and the kneading shaft 1 includes the aforementioned first flat limiting portion 11 (see...). Figure 7 , Figure 8The second mounting assembly 230 includes a second mounting block 233 adapted to the first flat limiting part 11 and a second mounting hole. The second mounting block 233 has a second mounting hole for passing through the first flat limiting part 11. At least a portion of the second mounting block 233 passes through the mounting holes of the second deflecting seat 231 and the fourth end cap 232, and the second mounting block 233 is detachably connected to the second deflecting seat 231 and / or the fourth end cap 232. For example, the second mounting block 233 is embedded in the side of the second deflecting seat 231 facing the fourth end cap 232 and is fixedly connected to the second deflecting seat 231, so that the kneading shaft 1 and the second mounting assembly 230 are relatively fixed to each other along the circumference of the kneading shaft 1. When the kneading shaft 1 is rotated under the drive of the output shaft 31, the first flat limiting part 11 can ensure that the rotating kneading shaft 1 can drive the second deflecting seat 231 and the fourth end cap 232 to rotate, thereby driving the second massage assembly 200 to move to achieve kneading massage. The detachable connection between the second deflector 231 and the fourth end cap 232, and the detachable connection between the second assembly block 233 and the second deflector 231 and / or the fourth end cap 232, may be, but are not limited to, threaded connection or snap-fit ​​connection, and no limitation or elaboration is made in this regard.

[0080] Of course, in other embodiments of this utility model, the second mounting component 230 may not have the second assembly block 233, but the through holes of the second deflection seat 231 and the fourth end cap 232 may be designed to fit the first flat limiting part 11, so that the second deflection seat 231 and the fourth end cap 232 are sleeved on the first flat limiting part 11, and the kneading shaft 1 and the second mounting component 230 may be fixed relative to each other along the circumference of the kneading shaft 1.

[0081] It should be noted that, in the embodiments of this utility model, such as Figure 16 As shown, the outer peripheral wall of the second ring 2202 is provided with a limiting block 2201, and the mounting cover 901 is correspondingly provided with a limiting groove 9011 for receiving the limiting block 2201. The groove wall of the limiting groove 9011 can limit the limiting block 2201, so as to ensure that the second connecting arm 220 drives the second massage head 210 to swing around the kneading shaft 1 instead of rotating at least one revolution, thereby ensuring that the second massage head 210 can perform kneading massage normally. Similarly, the slot 9022 opened in the aforementioned mounting base 902 can also limit the movement of the connecting rod 120 and the second connecting arm 220, thereby limiting the movement of the first massage head 110 and the second massage head 210, which will not be elaborated further. The limiting block 2201 can be integrally formed with the second ring 2202, or it can be formed separately and connected to the second ring 2202. The shape of the limiting block 2201 is not limited to cylindrical or spherical.

[0082] Preferably, please combine Figures 3 to 6 , Figures 14 to 16 In the first embodiment of this utility model, the main body of the massage mechanism 1000 further includes an adjusting shaft 7 and an adjusting mechanism 8. The adjusting shaft 7 is coaxially arranged with the kneading shaft 1, and at least a portion of the adjusting shaft 7 is exposed outside the kneading shaft 1. The adjusting mechanism 8 includes an adjusting component, which is located on the portion of the adjusting shaft 7 exposed outside the kneading shaft 1 and is drively connected to at least one of the two second massage components 200. The adjusting component is configured to drive at least one of the two second massage components 200 to move along the axial direction of the adjusting shaft 7 under the action of a power source. In this embodiment, by setting the adjusting shaft 7 and the adjusting mechanism 8 to drive at least one of the two second massage components 200 to move along the axial direction of the adjusting shaft 7, that is, along the axial direction of the kneading shaft 1, the massage distance between the two second massage components 200 can be adjusted. This allows the distance between the two second massage components 200 to be adjusted to the optimal massage distance according to different massage areas or the body shape differences of different users, thereby improving massage comfort and massage effect.

[0083] Specifically, in Figures 3 to 6 , Figures 14 to 16In the example, the portion of the adjustable shaft 7 exposed above the kneading shaft 1 is provided with a first threaded connection 811. The adjusting assembly includes a screw tube 82 with a fixed circumferential position, meaning the screw tube 82 cannot rotate. The screw tube 82 is rotatably connected to the second massage assembly 200, and the screw tube 82 is provided with a second threaded connection 821 threadedly connected to the first threaded connection 811. The screw tube 82 and the second massage assembly 200 are relatively fixed relative to each other along the axial direction of the adjustable shaft 7, and the screw tube 82 and the second massage assembly 200 can rotate relative to each other circumferentially along the adjustable shaft 7. The first threaded connection 811 is configured to rotate under the action of a power source, thereby driving the screw tube 82 to move axially along the adjustable shaft 7, and the screw tube 82 drives the second massage assembly 200 to move axially along the adjustable shaft 7. In this embodiment, the adjusting assembly of the adjusting mechanism 8 is based on the transmission principle of a screw pair to realize the adjustment of the massage distance between the two second massage assemblies 200. It not only achieves stepless adjustment but also has a self-locking function to prevent adjustment failure. It can be understood that by rotating the first screw connection 811 in different directions, the screw tube 82 can be driven to move the connected second massage component 200 along the kneading shaft 1 in different directions, thereby increasing or decreasing the massage distance between the two second massage components 200. For example, rotating the first screw connection 811 in the first direction can drive the screw tube 82 to move the connected second massage component 200 closer to the other second massage component 200, thereby decreasing the massage distance between the two second massage components 200. On the other hand, rotating the first screw connection 811 in the second direction (opposite to the first direction) can drive the screw tube 82 to move the connected second massage component 200 away from the other second massage component 200, thereby increasing the massage distance between the two second massage components 200.

[0084] More specifically, in this embodiment, a portion of the second massage component 200 (i.e., the portion of the aforementioned fourth end cap 232 and the second deflector seat 231 near the fourth end cap 232) is rotatably sleeved on the outside of the screw tube 82, and another portion of the second massage component 200 (the portion of the second deflector seat 231 away from the fourth end cap 232) is slidably sleeved on the outside of the kneading shaft 1. The second massage component 200 includes a deflection wheel (i.e., the second deflector seat 231) sleeved on the kneading shaft 1. A limiting structure is provided between the deflection wheel and the kneading shaft 1. This limiting structure allows the deflection wheel to move axially along the kneading shaft 1, and the limiting structure limits the deflection wheel and the kneading shaft 1 to be relatively fixed relative to each other circumferentially along the kneading shaft 1, so that the second massage component 200 can be driven to move when the kneading shaft 1 rotates. In this embodiment, the second massage component 200 and the screw tube 82 are sleeved on each other, which can reduce the axial dimension of the massage mechanism 1000 along the kneading shaft 1. It is understood that in other embodiments of this utility model, the second massage component 200 may not be sleeved on the screw tube 82, as long as the screw tube 82 is connected to the second massage component 200 and can rotate relative to it along the circumference of the kneading shaft 1, and there is no limitation thereto.

[0085] The limiting structure between the deflection wheel and the kneading shaft 1, namely the aforementioned first flat limiting part 11 and the through hole of the second mounting component 230, allows the second massage component 200 to be sleeved on the first flat limiting part 11 of the kneading shaft 1 through the through hole adapted to the first flat limiting part 11. This allows the screw tube 82 to move along the axial direction of the pitch adjusting shaft 7, which can drive the second massage component 200 to slide on the first flat limiting part 11 to adjust the massage distance between the two second massage components 200. At the same time, the first flat limiting part 11 can transmit the rotational driving force of the kneading shaft 1 to the second massage component 200, so that the second massage component 200 moves to perform kneading massage. It should be noted that, in this embodiment, the outer peripheral wall of the screw tube 82 may be provided with a ring-shaped protrusion. The ring-shaped protrusion is rotatably clamped between the second deflection seat 231 and the fourth end cap 232 connected together, so that the screw tube 82 is connected to the second massage component 200 and can rotate relative to the second massage component 200. In this way, the non-rotatable screw tube 82 will not affect the movement of the second massage component 200 under the drive of the kneading shaft 1, and can also drive the second massage component 200 to move along the axial direction of the kneading shaft 1.

[0086] Optionally, in Figures 3 to 6 , Figures 14 to 16In the example, the mounting cover 901 is provided with a limiting groove 9011 extending axially along the kneading shaft 1. The adjusting assembly also includes an anti-rotation rod 83. One end of the anti-rotation rod 83 is slidably inserted into the limiting groove 9011 of the mounting cover 901, and the other end of the anti-rotation rod 83 is connected to the screw tube 82. The inner wall of the limiting groove 9011 limits the rotation of the anti-rotation rod 83 around the screw tube 82, so that the screw tube 82 is relatively fixed circumferentially along the kneading shaft 1. That is, in this embodiment, the screw tube 82 is limited to not rotate by setting an anti-rotation rod 83 with one end limited by the mounting cover 901, ensuring that the rotation of the first screw connection 811 can drive the screw tube 82 to move axially along the adjusting shaft 7. Of course, in other embodiments of this utility model, other methods can be used to limit the screw tube 82 from rotating, such as, but not limited to, the housing 900 directly providing a limiting rod, and the screw tube 82 having a flat limiting part on its outside. By stopping the flat limiting part with the limiting rod, the screw tube 82 can also be limited to not rotating.

[0087] Alternatively, such as Figure 6 and Figure 16 As shown, in the first embodiment of this utility model, a portion of the screw tube 82 is sleeved with the first screw connection 811, and the other portion of the screw tube 82 is sleeved with the kneading shaft 1. By simultaneously sleeved with both the first screw connection 811 and the kneading shaft 1, the axial size of the massage mechanism 1000 along the kneading shaft 1 can be reduced. Of course, in other embodiments of this utility model, the screw tube 82 may only be sleeved with the first screw connection 811, and this is not limited.

[0088] exist Figures 3 to 6 , Figures 14 to 16 In the example, the adjustable shaft 7 is coaxially sleeved in the kneading shaft 1, and at least one end of the adjustable shaft 7 extends out of the kneading shaft 1. The first screw connection 811 is provided on the outer peripheral wall of the portion of the adjustable shaft 7 that extends out of the kneading shaft 1. In this embodiment, the pounding shaft 2 is sleeved in the output shaft 31 of the drive motor 3, and the adjustable shaft 7 is sleeved in the kneading shaft 1. The "dual-axis central shaft" structural design is beneficial to further reduce the size of the massage mechanism 1000.

[0089] In this embodiment, the adjusting assembly further includes a threaded sleeve 81, which is fixedly sleeved on the portion of the adjusting shaft 7 that extends out of the kneading shaft 1. The outer peripheral wall of the threaded sleeve 81 is provided with external threads. The screw tube 82 is provided with internal threads that are adapted to the external threads of the threaded sleeve 81. The external threads of the threaded sleeve 81 constitute the first screwed portion 811, and the internal threads of the screw tube 82 constitute the second screwed portion 821. The threaded sleeve 81 can be, but is not limited to, being circumferentially fixed to the adjusting shaft 7 by means of a pin. Of course, in other embodiments of this utility model, when the adjusting assembly is provided only at one end of the adjusting shaft 7, the portion of the adjusting shaft 7 that extends out of the kneading shaft 1 can be directly provided with external threads on the outer peripheral wall at one axial end. The external threads of this portion are adapted to the internal threads of the screw tube 82, and the external threads on the outer peripheral wall of the adjusting shaft 7 also constitute the first screwed portion 811, thereby eliminating the need for the threaded sleeve 81. In the embodiments of this utility model, the first threaded part 811 and the second threaded part 821 are mutually compatible external threads and internal threads, which makes the implementation simple and easy to manufacture the threaded parts.

[0090] Optionally, please refer to Figures 3 to 5 as well as Figure 16 In the first embodiment of this utility model, the power source for driving the first screwed part 811 to rotate around the adjusting shaft 7 is human power. The adjusting mechanism 8 also includes an adjusting knob 84, which is connected to the adjusting shaft 7 or the first screwed part 811. The adjusting knob 84 is configured to drive the adjusting shaft 7 to rotate under human power, thereby driving the first screwed part 811 to rotate, or to directly drive the first screwed part 811 to rotate. In this embodiment, the first screwed part 811 is driven to rotate by manually rotating the adjusting knob 84, eliminating the need for a drive motor, which helps reduce the cost of the massage mechanism 1000 and simplify its structure. Of course, in other embodiments of this utility model, a drive motor can also be used to drive the first screwed part 811 to rotate around the adjusting shaft 7, and this is not limited.

[0091] exist Figures 3 to 5 as well as Figure 16In the example, the adjustment assembly also includes a transmission gear 85, which is connected to the pitch adjustment shaft 7 or the first screw connection 811. The transmission gear 85 is relatively fixed to the pitch adjustment shaft 7 and the first screw connection 811 in the circumferential direction. The transmission gear 85 is provided with a first meshing part 851, and the adjustment knob 84 is provided with a second meshing part 841. The first meshing part 851 and the second meshing part 841 mesh. When the adjustment knob 84 is rotated under the action of human power, the adjustment knob 84 drives the transmission gear 85, the pitch adjustment shaft 7 and the first screw connection 811 to rotate. It is easy to understand that the adjustment knob 84 drives the adjusting shaft 7 to rotate through the transmission gear 85. The transmission ratio between the two meshing parts can be designed, thereby designing the ratio between the rotation angle of the adjustment knob 84 and the rotation angle of the adjusting shaft 7, so that the two are in a reasonable transmission ratio. This ensures that when the adjustment knob 84 is rotated to drive the adjusting shaft 7 and the first screw connection 811 to rotate, the rotation of the adjusting shaft 7 and the first screw connection 811 is relatively smooth. This ensures that the spacing adjustment of the two second massage components 200 is relatively smooth, and avoids poor adjustment effect due to excessive adjustment speed.

[0092] Specifically, in this embodiment, the mounting cover 901 is provided with a knob mounting groove 9012, and the adjusting knob 84 is rotatably mounted in the knob mounting groove 9012. The transmission gear 85 is fixedly sleeved on the end of the threaded sleeve 81 away from the second massage component 200, and the rotation axis of the adjusting knob 84 has an angle with the rotation axis of the transmission gear 85. The side of the adjusting knob 84 facing the transmission gear 85 is provided with a plurality of circumferentially arranged first helical teeth (see...). Figure 5 The transmission gear 85 has a plurality of second helical teeth arranged in a circumferential manner at one end near the adjustment knob 84. The plurality of first helical teeth (i.e., second meshing part 841) mesh with the plurality of second helical teeth (i.e., first meshing part 851) to realize the transmission connection between the adjustment knob 84 and the transmission gear 85.

[0093] The adjustment knob 84 can be directly installed in the knob mounting slot 9012, or it can be installed in the knob mounting slot 9012 via a mounting ring; there is no limitation on this.

[0094] Preferably, such as Figure 3 As shown, in the first embodiment of this utility model, a rotatable screw pull tab 86 is also provided on the outer surface of the adjustment knob 84. The user can rotate the adjustment knob 84 by pinching and rotating the screw pull tab 86, which is convenient for the user to operate.

[0095] Alternatively, such as Figure 3 , Figure 4 and Figure 16As shown, in the first embodiment of this utility model, the inner peripheral wall of the housing 900 (the inner peripheral wall of the knob mounting groove 9012) is provided with a first limiting part, and the outer peripheral wall of the adjusting knob 84 is provided with a second limiting part. The first limiting part and the second limiting part are adapted to prevent the adjusting knob 84 from rotating relative to the housing 900 when not subjected to human force. In this embodiment, by setting the mutually cooperating first limiting part and second limiting part, it is ensured that the adjusting knob 84 is fixed relative to the mounting cover 901 of the housing 900 when not subjected to rotational force, thereby ensuring that the massage distance between the two second massage components 200 remains unchanged after adjustment; furthermore, when the adjusting knob 84 is manually rotated, the relative sliding of the two limiting parts can generate sound feedback, indicating the angle of rotation of the adjusting knob 84.

[0096] Specifically, in Figure 3 , Figure 4 and Figure 16 In the example, the outer peripheral wall of the adjustment knob 84 is provided with multiple arc-shaped grooves 847 along the circumferential direction, and the inner peripheral wall of the knob mounting groove 9012 is provided with a limiting pin 87 with a ball head. When the adjustment knob 84 rotates around its own axis in the knob mounting groove 9012, the ball head of the limiting pin 87 can at least partially slide into at least one of the multiple arc-shaped grooves 847. The cooperation between the limiting pin 87 and the arc-shaped grooves 847 can not only play a role in stopping rotation and limiting movement, but also generate sound feedback. The ball head of the limiting pin 87 constitutes the first limiting part, and the multiple arc-shaped grooves 847 constitute the second limiting part. Of course, in other embodiments of this utility model, the first limiting part and the second limiting part can also adopt other combination structures, such as, but not limited to, the inner peripheral wall of the knob mounting groove 9012 being provided with multiple arc-shaped grooves 847, and the outer peripheral wall of the adjustment knob 84 being provided with a limiting pin 87 with a ball head. This is not limited.

[0097] Of course, in other embodiments of this utility model, the outer peripheral wall of the transmission gear 85 may be provided with a second limiting part, and this is not limited.

[0098] It is understood that in other embodiments of this utility model, the adjustment mechanism 8 may also take other forms, such as, but not limited to, the adjustment knob 84 being directly fixedly connected to the end of the adjustment shaft 7, thereby eliminating the need for the transmission gear 85.

[0099] Preferably, in Figures 3 to 6 , Figures 14 to 16In the example, there are two adjustment components, and two second massage components 200 are located between the two adjustment components. One adjustment component is driven to one of the two second massage components 200, and the other adjustment component is driven to the other of the two second massage components 200. Driven by the two adjustment components, the two second massage components 200 move towards or away from each other along the axial direction of the kneading shaft 1. By setting two adjustment components and driving the two second massage components 200 to move towards or away from each other along the axial direction of the kneading shaft 1, the adjustment efficiency of the massage spacing between the two second massage components 200 can be improved.

[0100] Specifically, in this embodiment, the two ends of the adjustable shaft 7 extend out from the two ends of the kneading shaft 1, and each end of the adjustable shaft 7 is provided with an adjustment component. The threads of the two first screw parts 811 located at the two ends of the adjustable shaft 7 are opposite in direction. Thus, when the adjustable shaft 7 is driven to rotate by adjusting the knob 84, the adjustable shaft 7 can simultaneously drive the two adjustment components to move, thereby causing the two second massage components 200 to move towards or away from each other along the axial direction of the kneading shaft 1.

[0101] Furthermore, in Figures 3 to 6 , Figures 14 to 16 In the example, the outer wall of the portion of the adjustable shaft 7 exposed above the kneading shaft 1 is provided with a third limiting structure; alternatively, the side wall of the limiting groove 9011 at the end of the kneading shaft 1 away from the two second massage components 200 in the axial direction constitutes a third limiting structure, wherein the third limiting structure is configured to limit the maximum distance between the two second massage components 200 in the axial direction of the kneading shaft 1. By providing the third limiting structure, the maximum massage distance between the two second massage components 200 in the axial direction of the kneading shaft 1 can be limited. And / or, the outer wall of the kneading shaft 1 is provided with a fourth limiting structure, which is configured to limit the minimum distance between the two second massage components 200 in the axial direction of the kneading shaft 1. By providing the fourth limiting structure, the minimum massage distance between the two second massage components 200 in the axial direction of the kneading shaft 1 can be limited. The third limiting structure may be, but is not limited to, the side wall at the end of the limiting groove 9011, or a limiting block or other limiting structure directly set on the outer wall of the adjusting shaft 7; the fourth limiting structure may be, but is not limited to, the first massage component 100 sleeved on the kneading shaft 1, or a stop ring or other limiting structure sleeved on the kneading shaft 1 ....

[0102] In the above embodiments, the adjustable distance shaft 7 is coaxially sleeved within the kneading shaft 1. It is understood that in other embodiments of this invention, the adjustable distance shaft 7 may also be coaxially sleeved outside at least one end of the kneading shaft 1, and the adjustable distance shaft 7 is located outside the two second massage components 200. A first threaded portion 811 is disposed at one end of the adjustable distance shaft 7 near the two second massage components 200 and threaded to the second threaded portion 821 of the screw tube 82. This also allows adjustment of the massage distance between the two second massage components 200, which will not be elaborated further. It is also understood that in other embodiments of this invention, the adjustable distance shaft 7 may also be coaxially disposed at the end of the kneading shaft 1, i.e., the adjustable distance shaft 7 and the kneading shaft 1 are not sleeved together. The outer peripheral wall of the adjustable distance shaft 7 is provided with a first threaded portion 811 and threaded to the second threaded portion 821 of the screw tube 82. This also allows adjustment of the massage distance between the two second massage components 200, which will not be elaborated further.

[0103] Preferably, please refer to again. Figure 1 and Figure 16 In the first embodiment of this utility model, at least one second massage component 200, which is connected to the adjustment component, is also provided with a slide rod 834. The mounting cover 901 is also provided with a guide groove 9014 that passes through both the inner and outer sides of the mounting cover 901. One end of the slide rod 834 is inserted into the guide groove 9014. Thus, when the second massage component 200 moves axially along the kneading shaft 1 to adjust the massage distance between the two second massage components 200, the user can know the current massage distance between the two second massage components 200 by observing the position of the slide rod 834 in the guide groove 9014. The slide rod 834 can be located at the end of the aforementioned anti-rotation rod 83 away from the screw tube 82. Optionally, the outer surface of the massage mechanism 1000 can be provided with multiple scale strips near the guide groove 9014. When the end of the slide rod 834 is aligned with different scale strips, it can indicate that the two second massage components 200 are at different distances. Further details are omitted here.

[0104] Please refer to the following: Figures 17 to 23 The massage mechanism 1000 provided in the second embodiment of this utility model has a structure that is roughly the same as that of the massage mechanism 1000 in the first embodiment. The difference is that in the second embodiment of this utility model, the first massage component 100 is directly rotatably connected to the connecting part 21 at the end of the hammering shaft 2.

[0105] For specific details, please refer to... Figures 19 to 22As shown, in the second embodiment of this utility model, the connecting part 21 is a bushing eccentrically sleeved on the end of the hammering shaft 2. The first massage assembly 100 includes a first swing arm 121 and a second swing arm 122. The portion between the two ends of the first swing arm 121 is rotatably sleeved on the bushing, and one end of the first swing arm 121 is rotatably connected to one end of the second swing arm 122. The other end of the first swing arm 121 is used to set the first massage head 110 (not shown in the figure). The other end of the second swing arm 122 is provided with a first collar 1203, and the first collar 1203 is sleeved on the first cylindrical assembly part 1311 of the first mounting assembly 130 (see figure). Figure 10 On the circumferential surface of the first mounting component 130, the structure can be referred to the relevant description in the first embodiment above, and will not be repeated here. However, unlike the first embodiment, in the second embodiment of this utility model, the axis of the first cylindrical assembly 1311 is parallel and spaced apart from the axis of the kneading shaft 1, and the axis of rotation of the first swing arm 121 relative to the second swing arm 122 is parallel to the axis of the kneading shaft 1, that is, parallel to the axis of the pounding shaft 2. In this embodiment, the first swing arm 121 and the second swing arm 122 constitute the aforementioned connecting rod 120 (see...). Figure 10 However, compared to the connecting rod 120 in the first embodiment, the linkage structure formed by the first swing arm 121 and the second swing arm 122 has an additional degree of rotational freedom, which is beneficial to improving the movement flexibility of the first massage component 100. Furthermore, the connection between any swing arm in the first massage component 100 and other rods is a rotational connection, which is easier to achieve than a hinge.

[0106] It is understood that, since the axis of the first cylindrical assembly 1311 in the second embodiment is parallel and spaced apart from the axis of the kneading shaft 1, when the first cylindrical assembly 1311 converts the rotational motion of the kneading shaft 1 into the swaying motion of the first massage component 100, the swaying trajectory is a “1” shaped trajectory along the direction perpendicular to the kneading shaft 1.

[0107] Furthermore, please combine Figures 17 to 22 The difference from the first embodiment lies in that, in the second embodiment of this utility model, the massage mechanism 1000 further includes a prompting mechanism 9. The prompting mechanism 9 is connected to the solenoid 82 or the anti-rotation rod 83, and is configured to indicate the current distance between the two second massage components 200. By setting the prompting mechanism 9, the user can intuitively understand the real-time distance between the two second massage components 200, which helps improve the accuracy of the user's adjustment of the massage distance between the two second massage components 200, allowing the user to quickly find a comfortable massage distance.

[0108] Specifically, in Figures 17 to 22In the example, the housing 900 has a visible area 9015, and the prompting mechanism 9 includes a prompting rod 91, which is connected to the anti-rotation rod 83 and has a prompting block 912. The prompting block 912 is directly opposite the visible area 9015. In response to the solenoid 82 driving the second massage component 200 to move axially along the adjusting shaft 7, the solenoid 82 drives the anti-rotation rod 83 to move axially along the adjusting shaft 7. The anti-rotation rod 83 can drive the prompting rod 91 to move, thereby causing the prompting block 912 to move within the visible area 9015 of the housing 900. Thus, the user can see the current position of the prompting block 912 within the visible area 9015. Based on the length of the visible area 9015 itself or the prompting mark 9016 (described later), the user can determine the current distance between the two second massage components 200.

[0109] For example, in one possible implementation, when the prompt block 912 is located at the extreme position at one end of the visible area 9015, it represents the maximum distance between the two second massage components 200, while when the prompt block 912 is located at the extreme position at the other end of the visible area 9015, it represents the minimum distance between the two second massage components 200. When the prompt block 912 is located between the extreme positions at both ends of the visible area 9015, the distance between the two second massage components 200 can also be calculated based on the ratio of the distance between the prompt block 912 and the extreme positions at both ends of the visible area 9015.

[0110] Preferably, such as Figure 17 As shown, in the second embodiment of this utility model, a prompt mark 9016 is provided on the outer surface of the massage mechanism 1000 near the visible area 9015. The prompt mark 9016 includes at least two scale bars for indicating different spacing values. By providing the prompt mark 9016 with multiple scale bars indicating different spacing values, when the prompt block 912 moves to align with any scale bar, the user can directly know the current spacing between the two second massage components 200.

[0111] Alternatively, such as Figures 18 to 22As shown, in the second embodiment of this utility model, the prompting mechanism 9 further includes a prompting window plate 92, which is installed on the housing 900 (e.g., detachably installed on the mounting cover 901). The prompting rod 91 is located on the side of the prompting window plate 92 near the kneading shaft 1 (not shown in the figure). An arc-shaped groove 922 is provided on the side of the prompting window plate 92 facing the prompting rod 91, corresponding to the visible area 9015. The first end of the prompting rod 91 is rotatably connected to the prompting window plate 92 or the housing 900. The second end of the prompting rod 91 is provided with a prompting block 912 protruding towards the prompting window plate 92. At least a portion of the prompting block 912 is slidably received in the arc-shaped groove 922. A connecting post 916 is provided between the two ends of the prompting rod 91 at the part facing away from the prompting window plate 92. An insertion groove 836 is provided on the anti-rotation rod 83, and the connecting post 916 is movably inserted into the insertion groove 836. Thus, when the anti-rotation rod 83 moves axially along the pitch adjustment shaft 7 (not shown in the figure) following the solenoid 82, the anti-rotation rod 83 can drive the indicator rod 91 to swing around its first end, thereby causing the indicator block 912 at the second end of the indicator rod 91 to slide in the arc-shaped groove 922 and be seen by the user through the visible area 9015. The user can know the current distance between the two second massage components 200 by looking at one of the scale bars of the indicator mark 9016 aligned with the indicator block 912.

[0112] It is easy to understand that in this embodiment, the prompting mechanism 9 adopts a combination of a prompting rod 91 and a prompting window plate 92, and the prompting rod 91 is set as a structure that can be driven by a movable anti-rotation rod 83 to swing. This structure is not only simple and easy to manufacture and install, but also, by reasonably designing the position of the connecting column 916 between the two opposite ends of the prompting rod 91, the movement stroke of the prompting block 912 can be made equal to the change in the distance between the two second massage components 200. In other words, the prompting mechanism 9 of this embodiment can amplify the axial movement stroke of a single second massage component 200 to the change in the distance between the two second massage components 200, thereby more intuitively displaying the current distance between the two second massage components 200.

[0113] The indicator window 92 can be embedded in the receiving groove of the mounting cover 901. Similarly, the indicator rod 91 can also be at least partially received in the receiving groove of the indicator window 92, so as not to increase the volume of the massage mechanism 1000.

[0114] In a second embodiment of this invention, the visible area 9015 of the housing 900 can be a perforated window, and the indicator window panel 92 is made of transparent material at least in the portion where the arc-shaped groove 922 is provided, so that the indicator block 912 located within the arc-shaped groove 922 can be seen by the user from outside the housing 900. In other embodiments of this invention, the visible area 9015 of the housing 900 can also be made of transparent material, and the arc-shaped groove 922 of the indicator window panel 92 is a perforated groove, which can also ensure that the indicator block 912 can be seen by the user from outside the housing 900.

[0115] Of course, in other embodiments of this utility model, the prompting mechanism 9 may omit the prompting window plate 92 and only use a swingable prompting rod 91. As long as the prompting block 912 of the prompting rod 91 swings under the drive of the anti-rotation rod 83 and can be seen by the user through the visible area 9015, it will not be described in detail.

[0116] Please see Figure 17 and Figure 23 The difference from the first embodiment is that in the second embodiment of this utility model, the transmission gear 85 is rotatably mounted on the mounting cover 901, and the adjustment knob 84 coaxially connected to the transmission gear 85 is a cap-shaped knob located outside the housing 900, which is convenient for the user to hold and rotate. In addition, in this embodiment, the aforementioned ball-headed limiting pin 87 is set in the positioning groove of the transmission gear 85 and is pressed and fixed by the adjustment knob 84. Multiple arc-shaped grooves are opened on the inner peripheral wall of the mounting cover 901, so that the limiting pin 87 and the multiple arc-shaped grooves are used to limit the transmission gear 85 and the adjustment knob 84, ensuring that the adjustment knob 84 is fixed relative to the mounting cover 901 of the housing 900 when it is not subjected to rotational force, thereby ensuring that the massage distance of the two second massage components 200 remains unchanged after adjustment.

[0117] It is understood that in the second embodiment of this utility model, since the prompting mechanism 9 is provided, the slide bar 834 and guide groove 9014 in the first embodiment can be omitted. Furthermore, in the second embodiment of this utility model, the other structures of the massage mechanism 1000 are basically the same as those in the first embodiment; please refer to the relevant description in the first embodiment for details, which will not be repeated here.

[0118] It should be noted that, similar to existing massage mechanisms, the massage mechanism 1000 provided in this embodiment of the present invention may also have other components or other structures, such as an energy storage battery, etc., which are not limited or described in detail. Furthermore, one or more bearings can be provided on the kneading shaft 1, the pounding shaft 2, etc. By providing bearings to support the shafts, the rotation of the shafts can be made more stable.

[0119] Furthermore, embodiments of this utility model also provide a massage device, which includes the massage mechanism 1000 described in any of the above embodiments. Therefore, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated further.

[0120] It should be noted that in the embodiments of this utility model, the massager may also include other components, such as, but not limited to, a binding component. The user binds the massager to the massage area using the binding component. The binding component can be an existing binding component of the massager, such as an elastic strap, and a control component for controlling the massager can be provided on the strap, which will not be elaborated further.

[0121] In the description of this utility model, the terms "embodiment," "specific embodiment," "example," etc., refer to a specific feature, structure, material, or characteristic described in connection with that embodiment or example, which is included in at least one embodiment or example of this utility model. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0122] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
