Abstract
Description
Technical Field
[0001] This utility model relates to the field of massage device technology, and in particular to a transmission mechanism, a massage core, and a massage device. Background Technology
[0002] In daily work, study, or leisure activities, people often experience discomfort in their muscles or bones due to maintaining improper postures for extended periods. In severe cases, this can even lead to illness, thus affecting their normal lives. To alleviate this discomfort, various types of massage devices have emerged on the market. These devices can massage areas such as the neck, shoulders, waist, back, and legs to relieve fatigue and discomfort, and have gained widespread popularity.
[0003] Currently, massagers with two drive shafts—a kneading shaft and a percussion shaft—are available on the market. Because the output shaft of the drive motor rotates at a high speed during operation, a transmission mechanism is typically used to reduce the driving force of the motor and increase its torque before transmitting it to the two drive shafts to meet the needs of the massager. However, the transmission mechanism of existing massagers has the drawback of occupying a large amount of space, which is detrimental to the compact design of the massager. Utility Model Content
[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention provides a transmission mechanism, a massage core, and a massage device. The transmission mechanism has a simple structure and occupies little space, which helps to reduce the size of the massage core.
[0005] To achieve the above objectives, in a first aspect, the present invention provides a transmission mechanism for use in a massage mechanism, the massage mechanism including a first power source and a kneading shaft and a percussion shaft arranged in parallel, the first power source having an output shaft at one end in the axial direction, the transmission mechanism including a first transmission component and a second transmission component located on the side of the first power source having the output shaft, and the first transmission component and the second transmission component being spaced apart along the axial direction of the output shaft.
[0006] The first transmission component is connected between the output shaft and the hammering shaft, and the second transmission component is connected between the output shaft and the kneading shaft. Both the first transmission component and the second transmission component include at least one of a belt pulley transmission pair, a worm gear transmission pair, and a gear transmission pair.
[0007] Secondly, this utility model provides a massage mechanism, including a kneading shaft, a percussion shaft parallel to the kneading shaft, and a transmission mechanism as described above.
[0008] Thirdly, this utility model provides a massager, including the massage mechanism described above.
[0009] In the transmission mechanism, massage core, and massager provided in this utility model embodiment, the transmission mechanism includes a first transmission component and a second transmission component. By setting the two transmission components on the same side of the first power source and distributing them axially at intervals along the output shaft, the transmission mechanism has a simple structure, occupies little space, and is conducive to achieving a compact design, thereby reducing the volume of the massage core.
[0010] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0043] The following detailed description, in conjunction with the accompanying drawings, further illustrates this utility model. Detailed Implementation
[0044] 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.
[0045] 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.
[0046] 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.
[0047] Please combine Figures 1 to 3 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 first power source 3, a first adjustment mechanism 4, and two first massage components 100. The kneading shaft 1, percussion shaft 2, first power source 3, and other components are housed within the housing 900, and the main body has at least one massage component (such as...). Figure 1The first massage element 110 and the second massage element 210 shown protrude from the housing 900. The massage elements are used to massage the massage area. In the embodiments of this utility model, the massage area may be, but is not limited to, the user's neck, shoulders, waist, back, or legs. The massage elements may perform kneading massage, percussion massage, or other massage methods on the massage area. The specific massage method is related to the movement structure of the massage elements, which will be described accordingly later.
[0048] like Figures 1 to 3 As shown, in an embodiment of this utility model, the housing 900 may include a mounting cover 901 and a mounting base 902 that is mated and connected to the mounting cover 901 (see Figure 902). Figure 24 The mounting cover 901 is not limited to a detachable connection such as a snap-fit or threaded connection with the mounting base 902, 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 first power source 3. The housing 900 is composed of the detachable mounting cover 901 and the mounting base 902, facilitating disassembly and assembly, and promoting 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.
[0049] Preferably, in an embodiment of this utility model, the massage mechanism 1000 further includes a bushing 903 made of an elastic material such as silicone (see...). Figure 23 The bushing 903 is attached to the side of the housing 900 where the massage element passes through (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 903 provides a smooth transition between the mounting base 902 and the user's massage area, preventing the hard mounting base 902 from causing discomfort to the user. It should be noted that the mounting base 902 has a slot or notch for the massage element to pass through, and when the massage mechanism 1000 is equipped with the bushing 903, the bushing 903 also has a corresponding opening for the massage element to pass through; this will not be elaborated further.
[0050] Preferably, please combine Figures 4 to 7In an embodiment of this utility model, the main body of the movement further includes a gearbox assembly 400 fixedly connected to the mounting cover 901 and / or mounting base 902, the gearbox assembly 400 being located within the accommodating space of the housing 900. The kneading shaft 1 and the hammering shaft 2 are mounted through the gearbox assembly 400, with both axial ends extending out of the gearbox assembly 400. The first power source 3, some components of the first adjusting mechanism 4, and the transmission mechanism 500 (described later) are housed and installed within the gearbox assembly 400. It is easy to understand that by providing the gearbox assembly 400 within the housing 900 to separately install different components, not only can the assembly efficiency and accuracy of each component be improved, but also the components can be separated, preventing interference between one component and another when a component shifts or shakes due to vibration, thereby improving the movement safety of each component. Optionally, in Figures 4 to 7 In the example, the jaw assembly 400 is composed of multiple (e.g., three or more) jaw housings, defining a first receiving cavity and a second receiving cavity. The first power source 3 is installed in the first receiving cavity, and some components of the first adjustment mechanism 4 and the transmission mechanism 500 are installed in the second receiving cavity. A receiving space can be defined between the jaw assembly 400, the mounting cover 901, and the mounting base 902 to accommodate the second adjustment mechanism 6, some components of the first massage assembly 100, some components of the second massage assembly 200 (described later), and the percussion transmission assembly 300 (described later), so that the massage assembly has sufficient space to move to ensure massage movement. At the same time, the distance between the two second massage assemblies 200 can be adjusted by setting the second adjustment mechanism 6 (described later). Of course, in other embodiments of this utility model, the gearbox assembly 400 may define a receiving cavity in which the first power source 3, some components of the first adjustment mechanism 4, and the transmission mechanism 500 are installed, or the gearbox assembly 400 may define three receiving cavities, so that the first power source 3, some components of the first adjustment mechanism 4, and the transmission mechanism 500 are respectively installed in one receiving cavity. In embodiments of this utility model, the gearbox assembly 400 preferably has a heat dissipation window or heat dissipation hole communicating with the receiving cavity in which the first power source 3 is installed. Those skilled in the art will understand that the specific structure of each gearbox housing of the gearbox assembly 400 can be designed according to actual needs, and will not be limited or described in detail.
[0051] Please refer to it again. Figure 3 and combined Figures 8 to 11In an embodiment of this utility model, two first massage components 100 are eccentrically and spaced apart on the kneading shaft 1, and the pounding shaft 2 is connected to the two first massage components 100. The kneading shaft 1 and the pounding shaft 2 are connected to the first power source 3 and are configured to drive the two first massage components 100 to move under the action of the first power source 3, thereby massaging the massage area through the first massage element 110 of the two first massage components 100. As mentioned above, the massage method of the first massage component 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 first power source 3, the first massage component 110 can perform kneading massage on the massage area. Another example is when the kneading shaft 1 and the percussion shaft 2 jointly drive the two first massage components 100 to move under the action of the first power source 3, the first massage component 110 can perform percussion massage on the massage area. Yet another example is when only the percussion shaft 2 drives the two first massage components 100 to move under the action of the first power source 3, the first massage component 110 can also perform percussion massage on the massage area. It should be understood that the percussion frequency of the first massage component 110 differs depending on whether the kneading shaft 1 and the percussion shaft 2 jointly drive the two first massage components 100 or only the percussion shaft 2 drives the two first massage components 100. More detailed descriptions will follow later and will not be elaborated here.
[0052] Both the kneading shaft 1 and the percussion shaft 2 can be directly connected to the first power source 3, or connected to the first power source 3 through a corresponding transmission mechanism. Preferably, the kneading shaft 1 and the percussion shaft 2 are connected to the first power source 3 through the same transmission mechanism 500. The transmission mechanism 500 is configured to reduce speed and increase torque, which helps to prevent the kneading shaft 1 from having poor massage effect due to high speed and low torque, and also prevents the percussion shaft 2 from having an excessively high percussion massage frequency of the first massage component 100, which could cause discomfort to the user. Furthermore, the fact that the kneading shaft 1 and the percussion shaft 2 are connected to the first power source 3 through the same transmission mechanism 500 helps to reduce the size of the massage mechanism 1000. Optionally, the first power source 3 can be a drive motor or manual power, preferably a drive motor, thereby reducing manual labor.
[0053] It is important to note that in the embodiments of this utility model, the first adjustment mechanism 4 is configured to drive the percussion shaft 2 to move relative to the kneading shaft 1 under the action of the second power source, so that the percussion shaft 2 can drive the two first massage components 100 to swing around the kneading shaft 1, so as to personalize the massage intensity of the first massage components 100, thereby improving the massage comfort and massage effect and meeting the needs of different users for massage intensity.
[0054] Preferably, in Figures 8 to 11In the example, the main body of the massage mechanism 1000 may further include two second massage components 200, which are spaced apart and sleeved on the kneading shaft 1. The kneading shaft 1 is configured to simultaneously drive the two first massage components 100 and the two second massage components 200 under the action of the first power source 3. 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, thereby 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 first massage components 100 and the two second massage components 200 to perform bilateral massage on the user, which helps to improve the massage effect. On the other hand, it can make the overall structure of the massage mechanism 1000 symmetrical, improving the overall aesthetics and working stability of the massage mechanism 1000. Of course, in other embodiments of this utility model, the massage mechanism 1000 may be provided with only one second massage component 200, and this is not limited. The second massage component 200 can be located on the outside of the two first massage components 100 or on the inside of the two first massage components 100, preferably on the outside of the two first massage components 100, in order to reduce the size of the first adjustment mechanism 4 and simplify the second adjustment mechanism 6 described later.
[0055] In embodiments of this utility model, the first massage component 100 and the second massage component 200 can be connected to the kneading shaft 1 with different structural designs, and the percussion shaft 2 can also be connected to the two first massage components 100 with different structural designs. Similarly, any of the mechanisms, such as the first adjustment mechanism 4, the second adjustment mechanism 6, and the transmission mechanism 500, can also adopt different structural designs to achieve the corresponding functions. The following will combine... Figures 1 to 29 The following is a further detailed description of the massage mechanism 1000 provided in the embodiments of this utility model.
[0056] Please combine Figures 12 to 15In the first embodiment of this utility model, the first massage assembly 100 includes a first massage member 110 and a first swing arm 120. The first massage member 110 is not limited to a spherical massage head or an ellipsoidal massage head. The first swing arm 120 includes a generally rod-shaped first swing arm body 121 and a first collar 122 connected to one end of the first swing arm body 121. The first massage member 110 is detachably or fixedly connected to the end of the first swing arm body 121 away from the first collar 122. The first collar 122 is preferably integrally formed with the first swing arm body 121. Further, the outer peripheral wall of the first collar 122 is provided with a hinge protrusion 1221. The first swing arm 120 also includes a first cover 123, which is detachably connected to the hinge protrusion 1221. A hinge hole is formed between the hinge protrusion 1221 and the first cover 123. This hinge hole is used to accommodate the hinge structure 3101 (e.g., [missing information]) at one end of the hammering transmission assembly 300. Figure 14 The other end of the hammering transmission assembly 300 (shown as a hinged ball head) is connected to the eccentric connecting part 21 (i.e., an eccentric column extending parallel to the axis of the hammering shaft 2) at one end of the hammering shaft 2, so that the hammering shaft 2 is connected to the first massage assembly 100 via the hammering transmission assembly 300, allowing the hammering shaft 2 to drive the first massage assembly 100 to oscillate around the kneading shaft 1. The specific structure of the hammering transmission assembly 300 will be described in detail later.
[0057] In the first embodiment of this utility model, the massage mechanism 1000 further includes a first mounting component 130, and each first massage component 100 is eccentrically mounted on the kneading shaft 1 through a first mounting component 130. Specifically, the first mounting component 130 includes a first deflection seat 131 and a first end cap 132. The first deflection seat 131 includes a first cylindrical assembly portion 1311 and a second end cap 1312. The second end cap 1312 is connected to one side of the first cylindrical assembly portion 1311. A first collar 122 is rotatably mounted on the circumferential surface of the first cylindrical assembly portion 1311. The first end cap 132 is detachably connected to the other side of the first cylindrical assembly portion 1311. The opposite sides of the first collar 122 are respectively limited by the second end cap 1312 and the first end cap 132, thereby allowing the first massage component 100 to be rotatably mounted on the first cylindrical assembly portion 1311. It should be noted that the first deflection seat 131 and the first 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 first 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. Among them, the axis of the first cylindrical assembly 1311 and the axis of the kneading shaft 1 are located on the same plane but have an included angle between them. The first mounting component 130 and the kneading shaft 1 have a first limiting mechanism, 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.
[0058] Those skilled in the art will understand that, in this embodiment, when the hammering shaft 2 rotates under the drive of the first power source 3, the eccentric connection 21 at the shaft end of the hammering shaft 2 will drive the first swing arm 120 and the first massage component 110 of the first massage component 100 to swing around the axis of the first cylindrical assembly 1311 through the hammering transmission assembly 300, that is, to swing around the kneading shaft 1; when the kneading shaft 1 rotates under the drive of the first power source 3, the kneading shaft 1 can drive the first deflection seat 131 and the first 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 deflection motion of the first swing arm 120 and the first massage component 110. The deflection trajectory is a figure-eight 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 element 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 element 110 is a composite motion trajectory of swaying motion and swinging motion. In this case, the frequency of the percussion shaft 2 driving the first massage component 100 to swing around the kneading shaft 1 is set to be greater than the swinging frequency generated by the kneading shaft 1 driving the first massage component 100 to swing around the kneading shaft 1. Therefore, the first massage component 100 can realize the percussion massage of the massage area.
[0059] 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 first swing arm 120 and the first massage component 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.
[0060] Optionally, in the first embodiment of this utility model, the first deflection seat 131 may be fixedly sleeved on the kneading shaft 1 by means of accessories such as a pin or a first assembly block 133; the first end cap 132 may be located on the side of the first cylindrical assembly portion 1311 away from the first power source 3, and the second end cap 1312 may be located on the side of the first cylindrical assembly portion 1311 close to the first power source 3, or the first end cap 132 may be located on the side of the first cylindrical assembly portion 1311 close to the first power source 3, and the second end cap 1312 may be located on the side of the first cylindrical assembly portion 1311 away from the first power source 3.
[0061] Alternatively, in the first embodiment of this utility model, the first limiting mechanism between the first mounting component 130 and the kneading shaft 1 includes a first flat limiting part 11 and a first mounting hole adapted to the first flat limiting part 11. The first flat limiting part 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 assembly block 133 has a first mounting hole for passing through the first flat limiting part 11. At least a portion of the first assembly block 133 passes through the mounting holes of the first deflection seat 131 and the first end cap 132. The first assembly block 133 is detachably connected to the first deflection seat 131 and / or the first end cap 132. For example, the first assembly block 133 is embedded in the side of the first deflection seat 131 away from the first end cap 132 and is fixedly connected to the first deflection seat 131, thereby fixing the kneading shaft 1 and the first mounting component 130 relatively to each other along the circumference of the kneading shaft 1. When the kneading shaft 1 rotates under the drive of the first power source 3, the first flat limiting part 11 ensures that the rotating kneading shaft 1 drives the first deflection seat 131 and the first end cap 132 to rotate, thereby driving the first massage component 100 to move to achieve the 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. The detachable connection between the first deflection seat 131 and the first end cap 132, and the detachable connection between the first assembly block 133 and the first deflection seat 131 and / or the first end cap 132, are not limited to threaded connections or snap-fit connections, and are not limited to or elaborated upon in this regard. 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 first end cap 132 may be designed to fit the first flat limiting part 11, so that the first deflection seat 131 and the first 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.
[0062] 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.
[0063] Please combine Figure 12 , Figure 13 , Figure 16 as well as Figure 17In the first embodiment of this utility model, the structure of the second massage component 200 is similar to that of the first massage component 100. The second massage component 200 includes a second massage element 210 and a second swing arm 220, and each second massage component 200 is sleeved on the kneading shaft 1 through a second mounting component 230. The second massage element 210 is disposed at one end of the second swing arm 220, and the second mounting component 230 is disposed at the other end of the second swing 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 element 210 to knead and massage the massage area.
[0064] Specifically, the second massage element 210 is disposed at one end of the second swing arm 220, and the other end of the second swing 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 2311 and a third end cap 2312. The third end cap 2312 is connected to one side of the second cylindrical assembly 2311. The second collar 2202 is rotatably fitted onto the circumferential surface of the second cylindrical assembly 2311. The fourth end cap 232 is detachably connected to the other side of the second cylindrical assembly 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 first power source 3, 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 2311 converts the rotational motion of the kneading shaft 1 into the deflection motion of the second swing arm 220 and the second massage member 210. The deflection trajectory is a figure-eight trajectory placed horizontally 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 second massage member 210 with the deflection motion.
[0065] Optionally, in the first embodiment of this utility model, the second deflection seat 231 may be fixedly sleeved on the kneading shaft 1 by means of accessories such as a pin or a second assembly block 233; the fourth end cover 232 may be located on the side of the second cylindrical assembly 2311 away from the first power source 3, and the third end cover 2312 may be located on the side of the second cylindrical assembly 2311 close to the first power source 3, or the fourth end cover 232 may be located on the side of the second cylindrical assembly 2311 close to the first power source 3, and the third end cover 2312 may be located on the side of the second cylindrical assembly 2311 away from the first power source 3.
[0066] Alternatively, 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 12 The second mounting assembly 230 includes a second mounting block 233, which has a second mounting hole for the first flat limiting part 11 to pass through. 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, thereby fixing the kneading shaft 1 and the second mounting assembly 230 relative to each other in the circumferential direction of the kneading shaft 1. When the kneading shaft 1 rotates, 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, are not limited to threaded connections or snap-fit connections, and are not limited or described in detail. Of course, in other embodiments of this utility model, the second mounting component 230 may not have the second assembly block 233, and the through holes of the second deflector 231 and the fourth end cap 232 may be designed to fit the first flat limiting part 11, so that the second deflector 231 and the fourth end cap 232 are sleeved on the first flat limiting part 11, which can also fix the kneading shaft 1 and the second mounting component 230 relatively along the circumference of the kneading shaft 1.
[0067] It should be noted that, in the first embodiment of this utility model, as Figure 3 and Figure 16As 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 swing arm 220 drives the second massage element 210 to swing around the kneading shaft 1 instead of rotating at least one revolution, thereby ensuring that the second massage element 210 can perform kneading massage normally. Similarly, the groove opened in the aforementioned mounting base 902 can also limit the movement of the first swing arm 120 and the second swing arm 220, thereby limiting the movement of the first massage element 110 and the second massage element 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 then connected to the second ring 2202. The shape of the limiting block 2201 is not limited to cylindrical or spherical.
[0068] Please combine Figures 13 to 15 and Figure 18 In embodiments of this utility model, the transmission connection between the percussion shaft 2 and the first massage component 100 can be achieved through various schemes. Specifically, in the first embodiment of this utility model, the massage mechanism 1000 further includes two percussion transmission components 300. The two percussion transmission components 300 are eccentrically and spaced apart at opposite ends of the percussion shaft 2. One of the two percussion transmission components 300 is connected to one of the two first massage components 100, and the other of the two percussion transmission components 300 is connected to the other of the two first massage components 100. The percussion shaft 2 drives the two first massage components 100 to swing around the kneading shaft 1 through the two percussion transmission components 300. In this embodiment, by setting the percussion transmission components 300 to achieve the connection between the percussion shaft 2 and the first massage component 100, compared to the direct transmission connection between the two ends of the percussion shaft 2 and the kneading shaft 1, the distance between the percussion shaft 2 and the kneading shaft 1 can be increased, thereby providing installation space for the first adjustment mechanism 4 and ensuring that the various components of the massage mechanism 1000 do not interfere with each other.
[0069] exist Figures 13 to 15 and Figure 18 In the example, the eccentric connecting portions 21 are respectively provided at both ends of the axial direction of the hammering shaft 2. The eccentric connecting portion 21 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 hammering transmission assembly 300 includes a connecting arm 310; wherein, one end of the connecting arm 310 is rotatably connected or hinged to the eccentric connecting portion 21 at the corresponding end of the hammering shaft 2, and the other end of the connecting arm 310 is rotatably connected or hinged to the corresponding first massage assembly 100. The eccentric connecting portion 21 adopts an eccentric column, and the hammering transmission assembly 300 adopts a single connecting arm 310, which has a simple structure and is easy to manufacture and assemble.
[0070] More specifically, in the first embodiment of this utility model, the kneading shaft 1 and the pounding shaft 2 are arranged in parallel. Two eccentric connecting portions 21 located at opposite ends of the pounding shaft 2 are symmetrical about the axis of rotation of the pounding shaft 2. Here, symmetry means that the two eccentric connecting portions 21 are located at opposite ends of the axial direction of the pounding shaft 2 and on opposite sides of the axis of rotation. One end of the connecting arm 310 is sleeved on the eccentric connecting portion 21, and the eccentric connecting portion 21 and the connecting arm 310 can rotate relative to each other. The other end of the connecting arm 310 is hinged to the hinge protrusion 1221 of the first massage component 100. In this embodiment, the kneading shaft 1 and the pounding shaft 2 are arranged in parallel, simplifying the structural design of the massage mechanism 1000 and making its assembly convenient.
[0071] Among them, such as Figure 14 and Figure 15 As shown, in the first embodiment of this utility model, the connecting arm 310 is provided with a hinge structure 3101 (specifically a hinge ball head) at one end for connecting the first massage component 100. The hinge structure 3101 is hinged in the hinge hole between the aforementioned hinge protrusion 1221 and the first cover 123, thereby realizing the connection between the percussion transmission component 300 and the first massage component 100. The connecting arm 310 is integrally formed with an arc-shaped connecting seat at one end for connecting the eccentric connecting part 21, and is detachably connected with an arc-shaped second cover 3102. The second cover 3102 and the connecting seat are engaged to form a receiving cavity. The receiving cavity is used to install the spherical bushing 3103 sleeved on the eccentric connecting part 21. One end of the bushing 3103 is limited by the step between the eccentric connecting part 21 and the percussion shaft 2, and the other end of the bushing 3103 is fixedly set on the eccentric connecting part 21 and other components for limitation, thereby enabling the eccentric connecting part 21 and the percussion shaft 2 to achieve a rotatable connection.
[0072] In other embodiments of this utility model, the percussion transmission assembly 300 can also adopt other structural components, which can also realize the transmission connection between the percussion shaft 2 and the first massage assembly 100. For example, but not limited to, the percussion transmission assembly 300 includes a first transmission arm and a second transmission arm. One end of the first transmission arm is rotatably connected to the eccentric connection part 21 at the corresponding end of the percussion shaft 2 and can rotate around the axis of the eccentric connection part 21. The other end of the first transmission arm is rotatably connected to one end of the second transmission arm, and the other end of the second transmission arm is hinged to the corresponding first massage assembly. In the first massage assembly 100, the rotation axis of the first transmission arm relative to the second transmission arm is perpendicular to the axis of the hammering shaft 2. The hammering transmission assembly 300 adopts a double transmission arm and connects the hammering shaft 2 and the first massage assembly 100 through a double-axis staggered hinge. The overall structure is simple and easy to assemble and disassemble. The rotational connection between the first transmission arm and the eccentric connection part 21, the rotational connection between the first transmission arm and the second transmission arm, and the hinge connection between the second transmission arm and the first massage assembly 100 can all be achieved using existing technologies, which will not be elaborated here.
[0073] In other embodiments of this utility model, the connecting arm 310 can also be hinged to the eccentric connecting part 21. For example, but not limited to, a spherical bushing or a direct sampling ball head structure can be fixedly sleeved on the eccentric connecting part 21, and a corresponding hinge hole can be provided at one end of the connecting arm 310 for connecting to the hammering shaft 2, so that the connecting arm 310 is hinged to the eccentric connecting part 21. Similarly, the connecting arm 310 and the first massage component 100 can also be rotatably connected, which is not limited or described in detail.
[0074] Of course, in other embodiments of this utility model, the kneading shaft 1 and the pounding shaft 2 may not be arranged in parallel. The axial direction of the kneading shaft 1 and the axial direction of the pounding shaft 2 are at an angle. The eccentric connecting part 21 is an eccentrically arranged universal ball shaft. The universal ball shaft includes a connecting rod part and a ball head. The ball head is connected to the first end of the connecting rod part. The second end of the connecting rod part is connected to the corresponding end of the pounding shaft 2. The connecting rod part and the pounding shaft 2 are relatively fixed to each other along the circumference of the pounding shaft 2. The ball head is hinged to one end of the connecting arm 310. The line connecting the first end and the second end of the connecting rod part is at an angle to the axial direction of the pounding shaft 2. The two connecting rod parts at both ends of the axial direction of the pounding shaft 2 are located in the same plane and are located on opposite sides of the rotation axis of the pounding shaft 2. This design allows the two first massage components 100 to alternately massage under the drive of the percussion shaft 2, so that the reaction forces of the two first massage components 100 cancel each other out and avoid a large difference in the percussion stroke when the two first massage components 100 are percussing the massage area.
[0075] Please combine Figures 10 to 13 and Figure 19In the first embodiment of this utility model, the first power source 3 (i.e., the drive motor) has an output shaft 31 at one end of its axial direction. The transmission mechanism 500 includes a first transmission component 510 and a second transmission component 520 located on the side of the first power source 3 with the output shaft 31. The first transmission component 510 and the second transmission component 520 are spaced apart along the axial direction of the output shaft 31. The first transmission component 510 is connected to the output shaft 31 and the hammering shaft 2, and the second transmission component 520 is connected to the output shaft 31 and the kneading shaft 1. Optionally, both the first transmission component 510 and the second transmission component 520 include at least one of a belt pulley transmission pair, a worm gear transmission pair, and a gear transmission pair. In this embodiment, the two transmission components of the transmission mechanism 500 are arranged on the same side of the first power source 3 and spaced apart along the axial direction of the output shaft 31, which makes the structure of the transmission mechanism 500 simple and occupies little space, which is conducive to achieving a compact design and thus reducing the volume of the massage core 1000.
[0076] Specifically, in Figures 10 to 13 , Figure 19 In the example, the first transmission assembly 510 includes a first pulley transmission pair 511 and a second pulley transmission pair 512, that is, the first transmission assembly 510 adopts a double pulley assembly. The first pulley transmission pair 511 includes a first driving pulley 5111, a first driven pulley 5112 and a first synchronous belt 5113. The first driving pulley 5111 is coaxially arranged with and relatively fixed to the output shaft 31 of the first power source 3. The first driven pulley 5112 is rotatably coaxially sleeved on the kneading shaft 1. The first synchronous belt 5113 drives the first driving pulley 5111 and the first driven pulley 5112. The diameter of the first driving pulley 5111 is smaller than the diameter of the first driven pulley 5112. The second pulley transmission pair 512 includes a second driving pulley 5121, a second driven pulley 5122, and a second synchronous belt 5123. The second driving pulley 5121 is rotatably coaxially sleeved on the kneading shaft 1 and fixed relative to the first driven pulley 5112. The second driven pulley 5122 is coaxially sleeved on the pounding shaft 2 and configured to drive the pounding shaft 2 to rotate. The second synchronous belt 5123 drives and connects the second driving pulley 5121 and the second driven pulley 5122. The diameter of the second driving pulley 5121 is smaller than the diameter of the second driven pulley 5122. When the second driven pulley 5122 is driven and connected to the pounding shaft 2, the output shaft 31 of the first power source 3 is driven and connected to the pounding shaft 2 through the first transmission assembly 510, which can play a dual role in speed reduction and torque amplification. This not only achieves a rapid speed reduction effect but also ensures smooth and reliable transmission.
[0077] The relative fixation between the first driving wheel 5111 and the output shaft 31 can be achieved using existing methods such as pin fixing. Both the first driven wheel 5112 and the second driving wheel 5121 are rotatably mounted on the kneading shaft 1 via bearings, and they are axially limited by bushings or other limiting components. This ensures that the first driven wheel 5112 and the second driving wheel 5121 can rotate relative to the kneading shaft 1 without axial movement. Further details are omitted. Optionally, the first driven wheel 5112 and the second driving wheel 5121 are fixedly connected or form an integral structure, preferably an integral structure. This not only simplifies the number of components in the first transmission assembly 510 and improves installation efficiency but also further ensures the synchronous rotation of the first driven wheel 5112 and the second driving wheel 5121.
[0078] exist Figures 10 to 13 , Figure 19 In the example, the second transmission assembly 520 includes a first worm gear transmission pair 521 and a second worm gear transmission pair 522, that is, the second transmission assembly 520 adopts a double worm gear assembly. The first worm gear transmission pair 521 includes a first worm 5211 and a first worm wheel 5212, and the second worm gear transmission pair 522 includes a second worm 5221 and a second worm wheel 5222. The first worm 5211 is coaxially arranged and relatively fixed with the output shaft 31, the first worm wheel 5212 meshes with the first worm 5211, and the second worm 5221 is coaxially arranged and relatively fixed with the first worm wheel 5212. The second worm wheel 5222 is fixedly sleeved on the kneading shaft 1 and meshes with the second worm 5221. In this way, the output shaft 31 of the first power source 3 is connected to the kneading shaft 1 through the second transmission assembly 520, which can play a dual role in speed reduction and torque amplification, and has the effects of fast speed reduction and smooth transmission.
[0079] The first worm gear 5212 and the second worm 5221 can be fixedly connected or be an integral structure, preferably an integral structure to simplify the number of components in the second transmission assembly 520 and improve installation efficiency. The integral first worm gear 5212 and the second worm 5221 are rotatably mounted in the aforementioned gearbox assembly 400 via a pair of bearings, which will not be described in detail.
[0080] Optionally, in Figures 10 to 13 , Figure 19 In the example, the axial direction of the first worm gear 5212 and the second worm 5221 is perpendicular to the axial direction of the first worm 5211, and / or the second worm 5221 passes between the kneading shaft 1 and the pounding shaft 2, which helps to reduce the volume of the second transmission assembly 520 and further improve the compact design of the transmission mechanism 500.
[0081] Optionally, in Figures 10 to 13 , Figure 19In the example, the second worm gear 5222 has a mounting groove extending radially therein. A transmission block is fixedly fitted onto the part of the kneading shaft 1 where the second worm gear 5222 is mounted. The transmission block is housed and installed in the mounting groove of the second worm gear 5222, thereby fixing the second worm gear 5222 onto the kneading shaft 1. By adding a transmission block between the second worm gear 5222 and the kneading shaft 1, the torsional driving arm of the second worm gear 5222 on the kneading shaft 1 can be increased, making it easier to drive the kneading shaft 1 to rotate, thereby reducing the output load of the first power source 3. Of course, in other embodiments of this utility model, the second worm gear 5222 can also be directly fixed onto the kneading shaft 1 by means of components such as pins.
[0082] Preferably, such as Figure 19 As shown, in the first embodiment of this utility model, the first drive wheel 5111 and the first worm gear 5211 are an integral transmission sleeve shaft, and the portion of the transmission sleeve shaft with the first drive wheel 5111 is directly and coaxially fixed to the end of the output shaft 31 by any means such as snap-fit connection, welding, or interference fit connection. In this embodiment, making the first drive wheel 5111 and the first worm gear 5211 an integral structure can further simplify the structure of the transmission mechanism 500 and improve installation efficiency; and the output shaft 31 is respectively connected to the kneading shaft 1 and the pounding shaft 2 through different transmission components. The output shaft 31 does not need to be specially designed, has a simple structure, is easy to manufacture, and helps to reduce the difficulty of selecting the drive motor (first power source 3); furthermore, the transmission sleeve shaft sleeved outside the output shaft 31 can be flexibly designed as needed and is easy to disassemble and maintain.
[0083] Of course, 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. The first connecting part constitutes a first driving wheel 5111, and the second connecting part constitutes a first worm gear 5211. Similarly, the output shaft 31 can be connected to the kneading rotating shaft 1 and the pounding rotating shaft 2 respectively through the first transmission assembly 510 and the second transmission assembly 520. In this way, it is not necessary to additionally set the first driving wheel 5111 and the first worm gear 5211, simplifying the structure and installation steps of the transmission mechanism 500. It can also be understood that in other embodiments of this utility model, the first transmission assembly 510 and the second transmission assembly 520 can also adopt other forms of transmission mechanisms, such as the first transmission assembly 510 adopting a worm gear transmission mechanism and the second transmission assembly 520 adopting a belt pulley transmission mechanism. This is not limited or elaborated.
[0084] Preferably, such as Figure 13As shown, in the first embodiment of this utility model, the axis of the kneading shaft 1 has a first projection point on the reference plane, the axis of the pounding shaft 2 has a second projection point on the reference plane, and the axis of the output shaft 31 of the first power source 3 has a third projection point on the reference plane. The first, second, and third projection points are connected sequentially to form a triangle. The reference plane is any plane that is perpendicular to the axis of the kneading shaft 1, the axis of the pounding shaft 2, and the axis of the output shaft 31. By limiting the projection points of the axis of the kneading shaft 1, the pounding shaft 2, and the output shaft 31 to form a triangle, it can be ensured that the three are compactly distributed, thereby reducing the volume of the massage mechanism 1000. More preferably, in this embodiment, the first, second, and third projection points are connected sequentially to form an acute triangle, thereby making the kneading shaft 1, the pounding shaft 2, and the output shaft 31 as compactly distributed as possible, which is beneficial to further reducing the volume of the massage mechanism 1000. Of course, in other embodiments of this utility model, the lines connecting the first projection point, the second projection point and the third projection point can also form a right triangle or an obtuse triangle, and there is no limitation thereto.
[0085] It should be noted that in the first embodiment of this utility model, by setting the reduction ratio of the first transmission component 510 to be less than the reduction ratio of the second transmission component 520, the frequency at which the first power source 3 drives the percussion shaft 2 to rotate is greater than the frequency at which the first power source 3 drives the kneading shaft 1 to rotate. This results in the frequency at which the percussion shaft 2 drives the first massage component 100 to oscillate around the kneading shaft 1 being greater than the oscillation frequency generated by the kneading shaft 1 driving the first massage component 100 around the kneading shaft 1, thus ensuring that the first massage component 100 can perform percussion massage when jointly driven by the kneading shaft 1 and the percussion shaft 2.
[0086] Optionally, in an embodiment of the present invention, the second transmission component 520 is configured to always enable the transmission connection between the output shaft 31 and the kneading shaft 1, so as to ensure that as long as the output shaft 31 rotates, it can drive the kneading shaft 1 to rotate, thereby enabling the kneading shaft 1 to drive the two first massage components 100 to move. The first transmission component 510 is configured to enable the transmission connection between the output shaft 31 and the pounding shaft 2 only when the output shaft 31 rotates in a preset direction, so that the output shaft 31 and the pounding shaft 2 can be engaged or disengaged as needed.
[0087] Specifically, in the embodiments of this utility model, 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 first transmission component 510. 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, users can adjust the massage mode of the two first massage components 100 by controlling the rotation direction of the output shaft 31 of the first power source 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 different massage needs of users.
[0088] For more details, please see Figure 19 and combined Figures 10 to 13 In 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 transmission mechanism 500 further includes a control component 530. The control component 530 is disposed between the second driven wheel 5122 and the hammering shaft 2. The control component 530 can operate in a first state and a second state. Specifically, in response to the output shaft 31 rotating in a first direction, the control component 530 operates in the first state. At this time, the second driven wheel 5122 is engaged with the hammering shaft 2 through the control component 530, and the rotation of the second driven wheel 5122 can drive the hammering shaft 2 to rotate. In response to the output shaft 31 rotating in a second direction, the control component 530 operates in the second state. At this time, the second driven wheel 5122 is disengaged from the hammering shaft 2 through the control component 530. In this embodiment, by setting a control component 530 between the hammering shaft 2 and the first transmission component 510, 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 first transmission component 510 to increase significantly.
[0089] Optionally, in Figure 19In the example, the control component 530 uses a one-way bearing. The inner ring of the one-way bearing is fixedly sleeved on the hammering shaft 2, and the second driven wheel 5122 is fixedly sleeved on the outer ring of the one-way bearing. It is easy to understand that, due to the working characteristics of the one-way bearing, when the output shaft 31 drives the second driven wheel 5122 to rotate in the first direction, the second driven wheel 5122 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 engage with the hammering shaft 2 through the control component 530 and the first transmission component 510. At this time, the hammering shaft 2 can drive the two first massage components 100 to rotate around the axis of the kneading shaft 1. The line swings; conversely, when the output shaft 31 drives the second driven wheel 5122 to rotate in the second direction, the second driven wheel 5122 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 hammering shaft 2 to rotate, so that the output shaft 31 is separated from the hammering shaft 2 through the control component 530 and the first transmission component 510. The hammering shaft 2 cannot drive the two first massage components 100 to swing around the axis of the kneading shaft 1.
[0090] Alternatively, in other embodiments of this utility model, the control component 530 may also adopt other forms of single components or combinations of multiple components. For example, but not limited to, the control component 530 may adopt 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, which is fixedly sleeved on the hammering shaft 2. The clutch sleeve is rotatably sleeved on the hammering shaft 2, and the fixed sleeve and the clutch sleeve are spaced apart along the axial direction of 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 5122 is fixedly sleeved on the outer peripheral wall of the clutch sleeve. Thus, in response to the second driven wheel 5122 rotating in the first direction, When the clutch sleeve, driven by the second driven wheel 5122, rotates the retaining spring in the direction of spring tightening, the retaining spring can grip the fixed sleeve (the retaining spring assembly is in the first state). The second driven wheel 5122 engages with the hammering shaft 2 through the retaining spring assembly, thereby driving the fixed sleeve and the hammering shaft 2 to rotate. Conversely, in response to the second driven wheel 5122 rotating in the second direction, the clutch sleeve drives the retaining spring to rotate in the opposite direction to the direction of spring tightening. The retaining spring can then loosen from the fixed sleeve and be fitted onto the fixed sleeve with a gap (the retaining spring assembly is in the second state). The retaining spring cannot drive the fixed sleeve and the hammering shaft 2 to rotate, and the second driven wheel 5122 separates from the hammering shaft 2 through the retaining spring assembly. The fixed sleeve can be, but is not limited to, being fixedly fitted onto the hammering shaft 2 by a pin or a flat limiting part; this is not limited.
[0091] It is understood that in other embodiments of this utility model, the transmission mechanism 500 may not be equipped with the control component 530, so that the output shaft 31 can be engaged with the percussion shaft 2 through the first transmission component 510 regardless of whether the output shaft 31 rotates forward or backward. Thus, as long as the output shaft 31 rotates, the percussion shaft 2 can drive 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 percussion massage under the dual driving action of the kneading shaft 1 and the percussion shaft 2. That is, when the transmission mechanism 500 is not equipped with the control component 530, the two first massage components 100 will only perform percussion massage regardless of whether the output shaft 31 rotates forward or backward.
[0092] Please combine Figure 8 , Figure 9 and Figure 20 In the first embodiment of this utility model, the first adjusting mechanism 4 includes at least a rotatable first adjusting member 41. The hammering shaft 2 is rotatably inserted through the first adjusting member 41, and the rotation axis of the hammering shaft 2 is parallel to the rotation axis of the first adjusting member 41, that is, the hammering shaft 2 is eccentrically inserted through the first adjusting member 41. It should be noted that the first adjusting member 41 is configured to rotate under the action of the second power source. Since the hammering shaft 2 is eccentrically inserted through the first adjusting member 41, the rotation of the first adjusting member 41 can drive the hammering shaft 2 to swing around the rotation axis of the first adjusting member 41, thereby enabling the hammering shaft 2 to move relative to the kneading shaft 1. As mentioned above, in this embodiment of the invention, the percussion shaft 2 is connected to the first massage component 100. Therefore, when the percussion shaft 2 moves relative to the kneading shaft 1, it can also drive the first massage component 100 to swing around the kneading shaft 1, changing the position of the first massage component 100 relative to the kneading shaft 1 in the massage mechanism 1000. This allows for personalized adjustment of the massage intensity of the first massage component 100, improving massage comfort and effect, and meeting the needs of different users for massage intensity. In this embodiment, by eccentrically inserting the percussion shaft 2 into the rotatable first adjusting member 41, the percussion shaft 2 can drive the first massage component 100 to swing relative to the kneading shaft 1 by rotating the first adjusting member 41, thereby achieving personalized adjustment of the massage intensity of the first massage component 100. The first adjusting mechanism 4 has a simple implementation principle and structure, and is easy to set up.
[0093] It is not difficult to understand that the first adjusting member 41 used to insert the hammering shaft 2 can rotate directly under the action of the second power source, or it can rotate under the action of other adjusting members (not limited to adjusting turntables and adjusting knobs) driven by the second power source.
[0094] exist Figure 8, Figure 9 as well as Figure 20 In the example, the first adjustment mechanism 4 also includes a second adjustment member 42 and a connecting rod 43. One end of the connecting rod 43 is connected to the first adjustment member 41, and the other end of the connecting rod 43 is movably connected to the second adjustment member 42. The second adjustment member 42 is connected to the first adjustment member 41 through the connecting rod 43. The second adjustment member 42 is configured to move under the action of a second power source, thereby driving the first adjustment member 41 to rotate through the connecting rod 43, so that the first adjustment member 41 drives the hammer shaft 2 to swing around the rotation axis of the first adjustment member 41. The connecting rod 43 and the first adjustment member 41 can be an integral structure or two parts connected together. There is a corresponding relationship between the movement stroke of the second adjustment member 42 and the rotation angle of the first adjustment member 41. In this embodiment, when the first adjusting member 41 is driven to rotate by the second adjusting member 42, the rotation angle of the first adjusting member 41 can be determined based on the correspondence between the movement stroke of the second adjusting member 42 and the rotation angle of the first adjusting member 41. This allows control of the rotation angle of the first adjusting member 41, enabling the percussion shaft 2 to move a specific distance relative to the kneading shaft 1, thus facilitating accurate adjustment of the massage intensity of the first massage component 100. It should be noted that in this embodiment, the movement stroke of the second adjusting member 42 is related to its specific movement form. For example, when the second power source drives the first adjusting member 41 to rotate by driving the second adjusting member 42 to rotate, the movement stroke of the second adjusting member 42 refers to the angle of rotation of the second adjusting member 42. Conversely, when the second power source drives the first adjusting member 41 to rotate by driving the second adjusting member 42 to swing, the movement stroke of the second adjusting member 42 refers to the angle of swing of the second adjusting member 42. Furthermore, it should be noted that in the embodiments of this utility model, the second adjusting member 42 is preferably provided with a self-locking structure. The self-locking structure is configured to restrict the first adjusting member 41 from rotating when it is not driven by the second adjusting member 42, thereby effectively preventing the first adjusting member 41 from rotating when it is not driven by the second adjusting member 42, and avoiding the adjustment failure of the first adjusting mechanism 4.
[0095] It is understood that in the embodiments of this utility model, the first adjusting member 41, the second adjusting member 42, and the self-locking structure can all adopt various structural designs. Specifically, please refer to... Figure 8 , Figure 9 , Figures 20 to 22 In the first embodiment of this utility model, the first adjusting member 41 is an eccentric adjusting bracket, and the second adjusting member 42 is a first adjusting knob. The eccentric adjusting bracket is rotatably mounted in the gearbox assembly 400, and the first adjusting knob is rotatably mounted on the mounting cover 901 (see...). Figure 1The first adjustment knob is installed in and exposed in the first knob mounting slot 9013. The first adjustment knob is connected to the eccentric adjustment bracket via a connecting rod 43 passing through the jaw assembly 400. In this embodiment, the first adjustment component 41 and the second adjustment component 42 are respectively components of a bracket and a knob, which are simple in structure and easy to manufacture and install. Furthermore, the second adjustment component 42 is exposed on the mounting cover 901, which makes it convenient for the user to directly manually operate the second adjustment component 42 to drive the first adjustment component 41 to rotate so that the percussion shaft 2 moves relative to the kneading shaft 1. That is, the second power source is human power, and there is no need to set a motor as the second power source in the massage mechanism 1000. This not only reduces the cost of the massage mechanism 1000, but also reduces the size of the massage mechanism 1000.
[0096] More specifically, such as Figure 8 and Figure 9 As shown, the eccentric adjustment bracket includes a bracket body 411 and two assembly parts 412. The bracket body 411 is generally boat-shaped, and the two assembly parts 412 are generally disc-shaped and are respectively connected to the two axial ends of the bracket body 411; the inner wall of the gearbox assembly 400 has two assembly slots 402 (see...). Figure 21 One of the two assembly parts 412 is rotatably mounted in one of the two assembly slots 402, and the other of the two assembly parts 412 is rotatably mounted in the other of the two assembly slots 402. The hammering shaft 2 is rotatably inserted through the two assembly parts 412 and is at least partially located in the eccentric adjustment bracket. The axis of rotation of the two assembly parts 412 does not coincide with the axis of rotation of the hammering shaft 2, so that the hammering shaft 2 is eccentrically inserted through the first adjustment member 41. In this embodiment, the eccentric adjustment bracket, which is the first adjustment member 41, is rotatably installed in the tooth box assembly 400 through the cooperation of the assembly part 412 and the assembly groove 402, making the installation simple. In addition, the bracket body 411 adopts a boat-shaped structure, which not only reduces the weight of the first adjustment member 41 to make the massage mechanism 1000 lighter, but also forms a receiving space between the bracket body 411 and the two assembly parts 412 to receive at least some components of the transmission mechanism 500, which is conducive to the compact design of the massage mechanism 1000 and reduces the volume of the massage mechanism 1000.
[0097] Preferably, in Figure 8 and Figure 9In the example, the two ends of the axial direction of the hammering shaft 2 extend out of the eccentric adjustment bracket, and one end of the hammering shaft 2 is connected to one of the two first massage components 100, while the other end of the hammering shaft 2 is connected to the other of the two first massage components 100. In this embodiment, the two ends of the hammering shaft 2 extend out of the eccentric adjustment bracket. Thus, when the hammering transmission components 300 for connecting the first massage components 100 are provided at both ends of the hammering shaft 2, the hammering transmission components 300 are located outside the eccentric adjustment bracket, which helps to reduce the volume of the eccentric adjustment bracket. Of course, in other embodiments of this utility model, the hammering transmission components 300 can also be provided at the position between the two ends of the hammering shaft 2, adjacent to the assembly part 412 of the eccentric adjustment bracket, to connect the first massage components 100. The hammering transmission components 300 are housed in the eccentric adjustment bracket and located between the two assembly parts 412. This will not be described in detail.
[0098] Furthermore, such as Figure 9 As shown, in the first embodiment of this utility model, since the pounding shaft 2 can move relative to the kneading shaft 1 under the drive of the first adjusting member 41, the pounding shaft 2 and the first power source 3 are connected by a pulley assembly (i.e., the first transmission assembly 510). The pulley assembly includes a second synchronous belt 5123 that is connected to the second driven wheel 5122 on the pounding shaft 2. Preferably, in this embodiment, the support body 411 is also provided with a rotatable tension wheel 414. The outer peripheral wall of the tension wheel 414 presses against and abuts against the outer peripheral wall of the second synchronous belt 5123. This ensures that the second synchronous belt 5123 remains taut and does not loosen during the movement of the pounding shaft 2 relative to the kneading shaft 1, so as to realize the synchronous transmission between the second driving wheel 5121 and the second driven wheel 5122. Of course, in other embodiments of this utility model, considering that the distance that the hammering shaft 2 moves relative to the kneading shaft 1 will not be large, the second synchronous belt 5123 can also be a synchronous belt with a suitable amount of elastic deformation. When the hammering shaft 2 moves relative to the kneading shaft 1, the second synchronous belt 5123 undergoes elastic deformation to always ensure the synchronous transmission between the second driving wheel 5121 and the second driven wheel 5122. In this way, the tension wheel 414 can be omitted, simplifying the structure of the massage mechanism 1000.
[0099] Preferably, please combine Figure 20 and Figure 21In the first embodiment of this utility model, the eccentric adjustment bracket is provided with a first limiting structure 413, and the dental assembly 400 is provided with a second limiting structure 403. The first limiting structure 413 and the second limiting structure 403 cooperate to limit the angle of rotation of the eccentric adjustment bracket under the action of the second power source. In this embodiment, by setting the appropriate first limiting structure 413 and second limiting structure 403, the eccentric adjustment bracket is limited to rotate within a reasonable angle range, which can ensure that the distance the hammering shaft 2 moves relative to the kneading shaft 1 is within a suitable range, thereby ensuring that the angle of swing of the first massage assembly 100 around the kneading shaft 1 is also within a suitable range, so that the massage intensity of the first massage assembly 100 can be adjusted within an appropriate range.
[0100] Specifically, in Figure 20 and Figure 21 In the example, at least one of the two assembly parts 412 is provided with a limiting groove, which extends circumferentially along the length of the assembly part 412, forming a first limiting structure 413; at least one of the two assembly grooves 402 has a limiting block protruding from its inner wall, which is received in the corresponding limiting groove, forming a second limiting structure 403. In this embodiment, the limiting groove and the limiting block cooperate to limit the rotation angle of the eccentric adjustment bracket. The implementation structure of the first limiting structure 413 and the second limiting structure 403 is simple and easy to manufacture. Of course, in other embodiments of this utility model, the first limiting structure 413 and the second limiting structure 403 can also adopt other implementation schemes, such as, but not limited to, the first limiting structure 413 using a limiting block and the second limiting structure 403 using a limiting groove, which is not limited.
[0101] Please combine Figure 7 , Figure 8 and Figure 22 In the first embodiment of this utility model, the first adjusting knob (i.e., the second adjusting member 42) has a spiral groove 421 on the side facing the eccentric adjusting bracket (i.e., the first adjusting member 41). The connecting rod 43 has a first end and a second end, the first end of the connecting rod 43 is fixedly connected to or detachably connected to the eccentric adjusting bracket, and the second end of the connecting rod 43 is provided with a first ball head 431. The gearbox assembly 400 has a slot 404 (see...). Figure 7The first ball head 431 is hinged in the spiral groove 421 of the first adjusting knob, allowing the first adjusting knob to be connected to the eccentric adjusting bracket via the connecting rod 43 with the ball head. It can be understood that since the first adjusting knob is rotatably mounted in the first knob mounting groove 9013 of the mounting cover 901, when the first adjusting knob rotates around its own axis under the action of human power (second power source), the first ball head 431 at one end of the connecting rod 43 will slide in the spiral groove 421. The connecting rod 43 can drive the eccentric adjusting bracket to rotate around the rotation axis of the assembly part 412, thereby driving the hammering shaft 2 to move relative to the kneading shaft 1. In this embodiment, the spiral groove 421 of the first adjustment knob can serve as a self-locking structure. When the first adjustment knob is not rotated manually, the inner wall of the spiral groove 421 will play a self-locking role to prevent the first ball head 431 from sliding, thereby avoiding the failure of the adjustment effect of the first adjustment mechanism 4. The spiral groove 421, as a self-locking structure, has a simple structure, is easy to manufacture, and has a low cost.
[0102] Preferably, such as Figure 8 As shown, in the first embodiment of this utility model, the rotation axis of the first adjusting knob (second adjusting member 42) is perpendicular to the rotation axis of the eccentric adjusting bracket (first adjusting member 41). By setting the rotation axis of the first adjusting knob perpendicular to the rotation axis of the eccentric adjusting bracket, when the first adjusting knob drives the eccentric adjusting bracket to rotate via the connecting rod 43, the first adjusting knob can be rotated more easily under the action of the second power source, especially when manually operating the first adjusting knob, which can save effort.
[0103] Alternatively, such as Figure 22 As shown, in the first embodiment of this utility model, the spiral groove 421 has at least one turn. By limiting the extension of the spiral groove 421 to at least one turn, the first adjustment knob does not need to be made very large, provided that the travel of the second adjustment member 42 (i.e., the rotation angle of the first adjustment knob) is sufficient to allow the first adjustment member 41 to rotate within the same angle range. This helps to reduce the volume of the first adjustment mechanism 4, and the rotation of the first adjustment knob can be very smooth during the adjustment process.
[0104] Furthermore, please combine Figure 3 and Figure 9In the first embodiment of this utility model, the first adjustment mechanism 4 further includes a first mounting ring 44 fixedly disposed on the mounting cover 901. The first adjustment knob is rotatably disposed in the first mounting ring 44. The inner peripheral wall of the first mounting ring 44 is provided with a first limiting part, and the outer peripheral wall of the first adjustment knob is provided with a second limiting part adapted to the first limiting part. The first limiting part and the second limiting part cooperate to prevent the first adjustment knob from rotating in the first mounting ring 44 when not subjected to the action of the second power source. In this embodiment, by setting the mutually cooperating first limiting part and second limiting part, it is ensured that the first adjustment knob is fixed relative to the first mounting ring 44 when not subjected to external force, thereby ensuring that the first adjustment knob remains stationary after adjusting the massage intensity of the first massage component 100, thus ensuring that the adjustment effect remains unchanged. In addition, when the first adjustment knob rotates, the relative sliding of the first limiting part and the second limiting part can generate sound feedback, which can serve to prompt the user of the rotation angle of the first adjustment knob.
[0105] exist Figure 3 and Figure 9 In the example, the outer peripheral wall of the first adjusting knob is provided with a plurality of first grooves 422 along the circumferential direction, and the inner peripheral wall of the first mounting ring 44 is provided with a second ball head 442. When the first adjusting knob rotates around its own axis in the first mounting ring 44, at least a portion of the second ball head 442 can slide into at least one of the plurality of first grooves 422. The second ball head 442 constitutes a first limiting part, and the plurality of first grooves 422 constitute a second limiting part. The cooperation between the second ball head 442 and the first grooves 422 can not only play a role in stopping rotation and limiting, but also generate sound feedback. The second ball head 442 can be fixedly set in the first mounting ring 44 or detachably set in the first mounting ring 44. In this embodiment, the first limiting part and the second limiting part adopt the implementation of the second ball head 442 and the plurality of first grooves 422, which has a simple structure. Of course, in other embodiments of this utility model, the first limiting part and the second limiting part may also adopt other combination structures, such as, but not limited to, the inner peripheral wall of the first knob mounting groove 9013 of the mounting cover 901 being provided with a plurality of first grooves 422, and the outer peripheral wall of the first adjusting knob being provided with a second ball head 442, which is not limited.
[0106] Furthermore, in Figure 3 and Figure 9 In the example, the inner peripheral wall of the first mounting ring 44 is provided with a bearing protrusion 441, which extends circumferentially around the first mounting ring 44. The side of the first adjusting knob facing the first adjusting member 41 is provided with a circular boss 423 (see Figure 22A spiral groove 421 is formed on a circular boss 423; wherein, the circular boss 423 is received within the space enclosed by the supporting protrusion 441, and the portion of the first adjusting knob facing the first adjusting member 41 adjacent to the circular boss 423 is placed on the supporting protrusion 441. In this embodiment, by setting the circular boss 423 and the supporting protrusion 441 to cooperate, the first adjusting knob can be quickly installed on the first mounting ring 44, and the supporting protrusion 441 can support the rotating first adjusting knob, which helps to ensure the smooth rotation of the first adjusting knob.
[0107] exist Figure 3 and Figure 9 In the example, the first adjustment mechanism 4 further includes a first torsion plate 45, which is connected to the side of the first adjustment knob facing away from the first adjustment member 41. The first torsion plate 45 is configured to drive the first adjustment knob to rotate under manual force. By setting the first torsion plate 45, it is convenient to manually rotate the first adjustment knob.
[0108] It is understood that in other embodiments of this utility model, the second adjusting member 42 may also be an adjusting member other than the first adjusting knob. For example, in some embodiments of this utility model, the second adjusting member 42 is a lever with a guide groove at one end, the guide groove extending along the length of the lever, and a transition hole provided between the two ends of the lever. The lever is rotatably connected to a fixed shaft through the transition hole. The lever is configured to rotate around the fixed shaft under the action of a second power source. The second end of the connecting rod 43 is slidably inserted into the guide groove of the lever, so that the lever is connected to the first adjusting member 41 through the connecting rod 43. When the second power source drives the lever to rotate around the fixed shaft, the rotation of the lever can drive the first adjusting member 41 to rotate. During the rotation of the lever, the second end of the connecting rod 43 slides in the guide groove. The lever has a damping gear in the transition hole, and the outer peripheral wall of the fixed shaft has meshing teeth. The meshing teeth and the damping gear mesh with each other to allow the lever to rotate around the fixed shaft under the action of the second power source, and the damping gear forms a self-locking structure. In this embodiment, the first adjusting member 41 is rotated by a lever based on the principle of lever, and the second adjusting member 42 is also relatively simple to use a lever; furthermore, a damping gear is set in the adapter hole of the lever to form a self-locking structure, which can prevent the lever from rotating when it is not subjected to external force, that is, it cannot drive the first adjusting member 41, thereby restricting the first adjusting member 41 from rotating when it is not driven by the second adjusting member 42. The self-locking structure is also simple and easy to implement.
[0109] It is also understood that in other embodiments of this utility model, the first adjustment mechanism 4 may also adopt other solutions besides the eccentric adjustment bracket and the first adjustment knob. For example, in some embodiments of this utility model, a bearing may be fixedly sleeved on the hammering shaft 2, and the first adjustment mechanism 4 includes a driving member. The driving member is connected to the bearing and is configured to drive the bearing and the hammering shaft 2 to move relative to the kneading shaft 1 under the action of a second power source. That is, in this embodiment, the driving member can directly push the hammering shaft 2 to move relative to the kneading shaft 1. The driving member may be a screw or a push rod, etc. Preferably, in a further embodiment, two bearings are fixedly sleeved at both ends of the percussion shaft 2. The first adjustment mechanism 4 includes two driving members, one of which is drive-connected to one of the two bearings, and the other of which is drive-connected to the other of the two bearings. The first adjustment mechanism 4 also includes an adjustment member and a connecting member. The adjustment member is drive-connected to the two driving members through the connecting member. The adjustment member is configured to simultaneously drive the two driving members to move the two bearings and the percussion shaft 2 relative to the kneading shaft 1 under the action of a second power source. It is easy to understand that by setting the adjustment member to simultaneously drive the two driving members to push the percussion shaft 2, the forces at both ends of the percussion shaft 2 can be balanced, and the structure of the massage mechanism 1000 can be made symmetrical. In one possible implementation, the adjusting component can be an adjusting knob, the driving component can be a screw, and the connecting component can be a gear, a synchronous pulley, or a flexible belt. In another possible implementation, the adjusting component can also be a paddle, the driving component can be a push rod, and the connecting component can be a connecting rod. The paddle is pushed and pulled to move the connecting rod and the two push rods connected to both ends of the connecting rod. This is not limited or described in detail.
[0110] Please combine Figures 3 to 5 , Figure 16 and Figure 17In the first embodiment of this utility model, the main body of the massage mechanism 1000 further includes an adjusting shaft 5 and a second adjusting mechanism 6. The adjusting shaft 5 is coaxially arranged with the kneading shaft 1, and at least a portion of the adjusting shaft 5 is exposed outside the kneading shaft 1. The second adjusting mechanism 6 includes an adjusting component, which is disposed on the portion of the adjusting shaft 5 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 5 under the action of a third power source. In this embodiment, by setting the adjustable shaft 5 and the second adjustment mechanism 6, at least one of the two second massage components 200 is driven to move along the axial direction of the adjustable shaft 5, that is, along the axial direction of the kneading shaft 1. The massage distance between the two second massage components 200 can be adjusted to the optimal massage distance according to the different massage areas or the body shape differences of different users. This can meet the massage needs of different users with different body shapes and the massage needs of users for different massage areas, thereby improving massage comfort and massage effect.
[0111] Specifically, in Figures 3 to 5 , Figure 16 and Figure 17In the example, the portion of the adjustable shaft 5 exposed above the kneading shaft 1 is provided with a first threaded connection 611. The adjusting assembly includes a screw tube 62 with a fixed circumferential position, meaning the screw tube 62 cannot rotate. The screw tube 62 is rotatably connected to the second massage assembly 200, and the screw tube 62 is provided with a second threaded connection 621 threadedly connected to the first threaded connection 611. The screw tube 62 and the second massage assembly 200 are relatively fixed relative to each other along the axial direction of the adjustable shaft 5, and the screw tube 62 and the second massage assembly 200 can rotate relative to each other circumferentially along the adjustable shaft 5. The first threaded connection 611 is configured to rotate under the action of a third power source, thereby driving the screw tube 62 to move axially along the adjustable shaft 5. The screw tube 62 drives the second massage assembly 200 to move axially along the adjustable shaft 5. In this embodiment, the adjusting assembly of the second adjusting mechanism 6 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 611 in different directions, the screw tube 62 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 611 in the first direction can drive the screw tube 62 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 611 in the second direction (opposite to the first direction) can drive the screw tube 62 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.
[0112] 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 62, 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 62 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 62, as long as the screw tube 62 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.
[0113] The limiting structure between the deflection wheel and the kneading shaft 1, namely the aforementioned second limiting structure, is also the aforementioned first flat limiting part 11 and the second flat limiting part on the inner wall of the second mounting hole. The second massage component 200 is sleeved on the first flat limiting part 11 of the kneading shaft 1 through the second mounting hole adapted to the first flat limiting part 11, so that the movement of the screw tube 62 along the axial direction of the adjusting shaft 5 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 62 may be provided with a ring-shaped protrusion. This ring-shaped protrusion is rotatably clamped between the second deflection seat 231 and the fourth end cap 232, which are connected together. This allows the screw tube 62 to be driven and connected to the second massage component 200 and to rotate relative to the second massage component 200. Thus, the non-rotatable screw tube 62 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. Of course, a limiting sleeve or the aforementioned transmission block can also be fixedly sleeved on the outer wall of the kneading shaft 1. The outer wall of the limiting sleeve or transmission block is provided with a first flat limiting part 11, so that it is not necessary to open a flat limiting part on the kneading shaft 1, making the kneading shaft 1 a complete shaft, which is easy to manufacture.
[0114] Optionally, in Figures 3 to 5 , Figure 16 and Figure 17In the example, the mounting cover 901 has a limiting groove 9011 extending axially along the kneading shaft 1. The adjusting assembly also includes an anti-rotation rod 63. One end of the anti-rotation rod 63 is slidably inserted into the limiting groove 9011 of the mounting cover 901, and the other end of the anti-rotation rod 63 is connected to the screw tube 62. The inner wall of the limiting groove 9011 limits the rotation of the anti-rotation rod 63 around the screw tube 62, so that the screw tube 62 is relatively fixed circumferentially along the kneading shaft 1. That is, in this embodiment, the screw tube 62 is limited to not rotate by setting an anti-rotation rod 63 with one end limited by the mounting cover 901, ensuring that the rotation of the first screw connection 611 can drive the screw tube 62 to move axially along the adjusting shaft 5. Of course, in other embodiments of this utility model, other methods can be used to limit the screw tube 62 from rotating, such as, but not limited to, the housing 900 directly setting a limiting rod, and the screw tube 62 having a flat limiting part on its outside. By stopping the flat limiting part with the limiting rod, the screw tube 62 can also be limited to not rotating.
[0115] Alternatively, such as Figure 3 and Figure 16 As shown, in the first embodiment of this utility model, a portion of the screw tube 62 is sleeved with the first screw connection 611, and the other portion of the screw tube 62 is sleeved with the kneading shaft 1. By simultaneously sleeved with both the first screw connection 611 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 62 may only be sleeved with the first screw connection 611, and this is not limited.
[0116] exist Figures 3 to 5 , Figure 16 and Figure 17 In the example, the adjustable shaft 5 is coaxially sleeved within the kneading shaft 1, and at least one end of the adjustable shaft 5 extends out of the kneading shaft 1. The first screw connection 611 is located on the outer peripheral wall of the portion of the adjustable shaft 5 that extends out of the kneading shaft 1. In this embodiment, the adjustable shaft 5 is sleeved within the kneading shaft 1, employing a "shaft-in-shaft" design, which helps to further reduce the size of the massage mechanism 1000.
[0117] In this embodiment, the adjusting assembly further includes a threaded sleeve 61, which is fixedly sleeved on the portion of the adjusting shaft 5 that extends out of the kneading shaft 1. The outer peripheral wall of the threaded sleeve 61 is provided with external threads. The screw tube 62 is provided with internal threads that are adapted to the external threads of the threaded sleeve 61. The external threads of the threaded sleeve 61 constitute the first threaded portion 611, and the internal threads of the screw tube 62 constitute the second threaded portion 621. The threaded sleeve 61 can be, but is not limited to, being circumferentially fixed to the adjusting shaft 5 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 5, the portion of the adjusting shaft 5 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 62, and the external threads on the outer peripheral wall of the adjusting shaft 5 also constitute the first threaded portion 611, thereby eliminating the need for the threaded sleeve 61. In the embodiments of this utility model, the first threaded part 611 and the second threaded part 621 are mutually compatible external threads and internal threads, which makes the implementation simple and easy to manufacture the threaded parts.
[0118] Optionally, please refer to Figures 3 to 5 In the first embodiment of this utility model, the third power source for driving the first screwed part 611 to rotate around the adjusting shaft 5 is human power. The second adjusting mechanism 6 also includes a second adjusting knob 64, which is tractively connected to the adjusting shaft 5 or the first screwed part 611. The second adjusting knob 64 is configured to drive the adjusting shaft 5 to rotate under human power, thereby driving the first screwed part 611 to rotate, or directly driving the first screwed part 611 to rotate. In this embodiment, the first screwed part 611 is driven to rotate by manually rotating the second adjusting knob 64, 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 611 to rotate around the adjusting shaft 5, and this is not limited.
[0119] exist Figures 3 to 5In the example, the adjustment assembly also includes a transmission gear 65, which is connected to the adjusting shaft 5 or the first screw connection 611. The transmission gear 65 is relatively fixed to the adjusting shaft 5 and the first screw connection 611 in the circumferential direction. The transmission gear 65 is provided with a first meshing part 651, and the second adjustment knob 64 is provided with a second meshing part 641. The first meshing part 651 and the second meshing part 641 mesh. When the second adjustment knob 64 is rotated under the action of human power, the second adjustment knob 64 drives the transmission gear 65, the adjusting shaft 5 and the first screw connection 611 to rotate. It is easy to understand that the second adjustment knob 64 drives the adjusting shaft 5 to rotate through the transmission gear 65. The transmission ratio between the two meshing parts can be designed, thereby designing the ratio between the rotation angle of the second adjustment knob 64 and the rotation angle of the adjusting shaft 5, so that the transmission ratio between the two is at a reasonable value. This ensures that when the second adjustment knob 64 is rotated to drive the adjusting shaft 5 and the first screw connection 611 to rotate, the rotation of the adjusting shaft 5 and the first screw connection 611 is relatively smooth, thereby ensuring that the spacing adjustment of the two second massage components 200 is relatively smooth and avoiding poor adjustment effect due to excessive adjustment speed.
[0120] Specifically, in this embodiment, the mounting cover 901 is provided with a second knob mounting groove 9014 (see...). Figure 1 The second adjusting knob 64 is rotatably mounted in the second knob mounting groove 9014. The transmission gear 65 is fixedly sleeved on the end of the threaded sleeve 61 away from the second massage component 200, and the rotation axis of the second adjusting knob 64 forms an angle with the rotation axis of the transmission gear 65. The side of the second adjusting knob 64 facing the transmission gear 65 has a plurality of circumferentially arranged first helical teeth (see...). Figure 5 The transmission gear 65 has multiple circumferentially arranged second helical teeth at one end near the second adjustment knob 64. Multiple first helical teeth (i.e., second meshing portions 641) mesh with multiple second helical teeth (i.e., first meshing portions 651), thereby achieving a transmission connection between the second adjustment knob 64 and the transmission gear 65. Preferably, the number of teeth in the first meshing portion 651 is less than the number of teeth in the second meshing portion 641, allowing the user to drive the adjustment shaft 5 to rotate with less force, thus adjusting the massage interval.
[0121] Preferably, in Figures 3 to 5In the example, the adjustment assembly also includes a second mounting ring 66, in which a second adjustment knob 64 is rotatably disposed. The inner peripheral wall of the second mounting ring 66 has a third limiting portion, and the outer peripheral wall of the second adjustment knob 64 or the transmission gear 65 has a fourth limiting portion. The third and fourth limiting portions are adapted to prevent the second adjustment knob 64 from rotating within the second mounting ring 66 without human intervention. Similar to the function of the first and second limiting portions, by providing the cooperating third and fourth limiting portions, it can be ensured that the second adjustment knob 64 is fixed relative to the second mounting ring 66 when no rotational force is applied, thereby ensuring that the massage distance between the two second massage components 200 remains unchanged after adjustment. Furthermore, when the second adjustment knob 64 is rotated, the relative sliding of the third and fourth limiting portions generates audible feedback, indicating to the user the angle of rotation of the second adjustment knob 64.
[0122] Specifically, in Figures 3 to 5 In the example, the outer peripheral wall of the second adjusting knob 64 is provided with a plurality of arc-shaped second grooves 642 along the circumferential direction, and the inner peripheral wall of the second mounting ring 66 is provided with a third ball head 662. When the second adjusting knob 64 rotates around its own axis in the second mounting ring 66, the third ball head 662 can at least partially slide into at least one of the plurality of arc-shaped second grooves 642. The cooperation between the third ball head 662 and the second groove 642 can not only play a role in stopping rotation and limiting movement, but also generate sound feedback. The third ball head 662 constitutes a third limiting part, and the plurality of arc-shaped second grooves 642 constitute a fourth limiting part. In other embodiments of the present invention, the third limiting part and the fourth limiting part can also adopt other combination structures, such as, but not limited to, the inner peripheral wall of the second mounting ring 66 being provided with a plurality of arc-shaped second grooves 642, and the outer peripheral wall of the second adjusting knob 64 being provided with a third ball head 662. This is not limited. In other embodiments of the present invention, the outer peripheral wall of the transmission gear 65 can also be provided with a fourth limiting part. This is not limited.
[0123] Of course, in other embodiments of this utility model, the second mounting ring 66 may not be provided, and the second adjusting knob 64 may be directly provided in the second knob mounting groove 9014, with a third limiting part provided on the inner wall of the second knob mounting groove 9014. This is not limited.
[0124] Preferably, such as Figure 4 As shown, in the first embodiment of this utility model, a rotatable second torsion plate 67 is also provided on the outer surface of the second adjustment knob 64. The user can rotate the second adjustment knob 64 by pinching and rotating the second torsion plate 67, which makes it easier and less strenuous for the user to rotate the second adjustment knob 64.
[0125] It is understood that in other embodiments of this utility model, the second adjustment mechanism 6 may also take other forms, such as, but not limited to, the second adjustment knob 64 being directly fixedly connected to the end of the adjustment shaft 5, thereby eliminating the need for the transmission gear 65.
[0126] Preferably, in Figures 3 to 5 In 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.
[0127] Specifically, in this embodiment, the adjustable shaft 5 is a single-piece shaft, with its opposite ends extending out from the opposite ends of the kneading shaft 1. Each end of the adjustable shaft 5 is equipped with an adjustment component, and the threads of the two first threaded portions 611 located at opposite ends of the adjustable shaft 5 are rotated in opposite directions. With this configuration, when the adjustable shaft 5 is driven to rotate by the second adjustment knob 64, the adjustable shaft 5 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. Furthermore, since the adjustable shaft 5 is a single-piece shaft, driving either the threaded sleeve 61 can drive the two second massage components 200 to move towards or away from each other, thus requiring only one second adjustment knob 64, simplifying the structure of the second adjustment mechanism 6.
[0128] Furthermore, in Figures 3 to 5In the example, the outer wall of the portion of the adjustable shaft 5 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 the 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 setting 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 setting 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 5; 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 ....
[0129] In the above embodiments, the adjustable distance shaft 5 is coaxially sleeved within the kneading shaft 1. It is understood that in other embodiments of this invention, the adjustable distance shaft 5 may also be coaxially sleeved outside at least one end of the kneading shaft 1, and the adjustable distance shaft 5 may be located outside the two second massage components 200. A first threaded portion 611 may be disposed at one end of the adjustable distance shaft 5 near the two second massage components 200 and threaded to the second threaded portion 621 of the screw tube 62. 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 5 may also be coaxially disposed at the end of the kneading shaft 1, i.e., the adjustable distance shaft 5 and the kneading shaft 1 are not sleeved together. A first threaded portion 611 is disposed on the outer peripheral wall of the adjustable distance shaft 5 and threaded to the second threaded portion 621 of the screw tube 62. This also allows adjustment of the massage distance between the two second massage components 200, which will not be elaborated further.
[0130] It is also understood that in other embodiments of this utility model, the adjustable shaft 5 may also consist of a first shaft segment and a second shaft segment that are coaxial and spaced apart. That is, the adjustable shaft 5 is composed of two independent shafts; the end of the first shaft segment away from the second shaft segment extends out of one end of the kneading shaft 1, and the end of the second shaft segment away from the first shaft segment extends out of the other end of the kneading shaft 1; one of the two adjustment components is located at the end of the first shaft segment extending out of the kneading shaft 1 and is drively connected to one of the two second massage components 200, and the other of the two adjustment components is located at the end of the second shaft segment extending out of the kneading shaft 1. One end is connected to the other of the two second massage components 200; wherein, the threads of the two first screw portions 611 included in the two adjustment components are opposite in direction, and each of the two first screw portions 611 is configured to drive the connected screw tube 62 to move axially along the adjusting shaft 5 under the action of a third power source, thereby driving the second massage component 200 connected to the screw tube 62 to move axially along the adjusting shaft 5, and when both screw tubes 62 included in the two adjustment components move axially along the adjusting shaft 5, the two screw tubes 62 move towards or away from each other along the axial direction of the adjusting shaft 5. In this embodiment, the adjusting shaft 5 adopts two segmented shafts, and compared with using a single shaft, the length of each shaft segment is correspondingly reduced, which helps to reduce the manufacturing difficulty of the shaft segment. It should be noted that in this embodiment, each adjustment component is provided with a corresponding second adjustment knob 64.
[0131] Furthermore, in other embodiments of this utility model, the adjusting component may also employ other implementations besides the threaded sleeve 61 and the screw tube 62. Exemplarily, in some embodiments of this utility model, the adjusting component includes a sleeve, which is slidably fitted onto the portion of the adjusting shaft 5 exposed above the kneading shaft 1, and the sleeve is rotatably connected to the second massage component 200; wherein the sleeve and the second massage component 200 are relatively fixed relative to each other along the axial direction of the adjusting shaft 5, and the sleeve and the second massage component 200 are rotatable relative to each other along the circumferential direction of the adjusting shaft 5. The sleeve is configured to move along the axial direction of the adjusting shaft 5 under the action of a third power source, thereby driving the second massage component 200 to move along the axial direction of the adjusting shaft 5. In this embodiment, driving the sleeve to slide along the adjusting shaft 5 can drive the second massage component 200 to move, achieving the purpose of adjusting the massage distance between the two second massage components 200. The adjusting component uses a slidable sleeve, which has a simpler structure compared to the helical pair assembly of the threaded sleeve 61 and the screw tube 62. Preferably, the housing 900 (e.g., mounting cover 901) has a through groove extending axially along the adjusting shaft 5. The adjusting assembly also includes a lever, one end of which is connected to the sleeve, and the other end of which passes through the through groove. The lever is configured to drive the sleeve to move axially along the adjusting shaft 5 under the action of a third power source. A self-locking structure is provided between the housing 900 and the lever, configured to provide a resisting force to prevent the lever from sliding freely within the through groove. By adding a self-locking structure between the housing 900 and the lever connected to the sleeve, a self-locking function is achieved, thereby preventing adjusting failure. In one possible implementation, the self-locking structure between the housing 900 and the lever includes an elastic self-locking head and multiple self-locking holes. The elastic self-locking head is located on the inner wall of the corresponding through groove of the lever, and the multiple self-locking holes are opened on the inner wall of the through groove and spaced apart along the axial direction of the adjusting shaft 5. When the lever moves axially along the adjusting shaft 5 under the action of a third power source, the elastic self-locking head elastically presses against the inner wall of the through groove. When the lever moves axially along the adjusting shaft 5 until the elastic self-locking head aligns with one of the multiple self-locking holes, the elastic self-locking head recovers its deformation and is at least partially received in the aligned self-locking hole, thereby realizing the self-locking function. Of course, the self-locking structure between the housing 900 and the lever can also be other structures, such as, but not limited to, multiple elastic ball heads protruding from the inner wall of the through groove. The distance between two elastic ball heads is equal to or slightly less than the thickness of the lever. When the lever moves, it presses against the elastic ball heads. When the lever is located between two elastic ball heads, the two elastic ball heads can provide a resisting force, which can also realize the self-locking function.
[0132] Please refer to the following: Figures 23 to 29The massage mechanism 1000 provided in the second embodiment of this utility model has a structure that is roughly the same as that in the first embodiment, except that in the second embodiment of this utility model, the first massage component 100 is directly rotatably connected to the eccentric connecting part 21 at the end of the hammering shaft 2.
[0133] For specific details, please refer to... Figures 25 to 28 As shown, in the second embodiment of this utility model, the eccentric connecting part 21 is a bushing eccentrically sleeved on the end of the hammering shaft 2. The first massage assembly 100 includes a first connecting rod 124 and a second connecting rod 125. The portion between the two ends of the first connecting rod 124 is rotatably sleeved on the bushing, and one end of the first connecting rod 124 is rotatably connected to one end of the second connecting rod 125. The other end of the first connecting rod 124 is used to set the first massage element 110 (not shown in the figure). The other end of the second connecting rod 125 is provided with a first collar 122, and the first collar 122 is sleeved on the first cylindrical assembly part 1311 of the first mounting assembly 130 (see figure). Figure 16 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 connecting rod 124 relative to the second connecting rod 125 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 connecting rod 124 and the second connecting rod 125 constitute the aforementioned first swing arm 120 (see...). Figure 16 However, compared to the first swing arm 120 in the first embodiment, the linkage structure formed by the first link 124 and the second link 125 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 link in the first massage component 100 and other links is a rotational connection, which is easier to achieve than a hinge.
[0134] 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.
[0135] Furthermore, please combine Figures 23 to 28The 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 62 or the anti-rotation rod 63, 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.
[0136] Specifically, in Figures 23 to 28 In the example, the housing 900 has a visible area 9015, and the prompting mechanism 9 includes a prompting rod 91 connected to an anti-rotation rod 63 and a prompting block 912, which faces the visible area 9015. In response to the solenoid 62 driving the second massage component 200 to move axially along the adjusting shaft 5, the solenoid 62 drives the anti-rotation rod 63 to move axially along the adjusting shaft 5. The anti-rotation rod 63 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.
[0137] 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.
[0138] Preferably, such as Figure 23 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.
[0139] Alternatively, such as Figures 27 to 28As 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. The anti-rotation rod 63 is provided with an insertion groove 636, and the connecting post 916 is movably inserted into the insertion groove 636. Thus, when the anti-rotation rod 63 moves axially along the adjusting shaft 5 (not shown in the figure) following the solenoid 62, the anti-rotation rod 63 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.
[0140] 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 63 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 equal to the change value of 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 value of the distance between the two second massage components 200, thereby more intuitively displaying the current distance between the two second massage components 200.
[0141] 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.
[0142] 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.
[0143] 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 63 and can be seen by the user through the visible area 9015, it will not be described in detail.
[0144] Please see Figure 23 and Figure 29 The difference from the first embodiment is that in the second embodiment of this utility model, the transmission gear 65 is rotatably mounted on the mounting cover 901, and the second adjustment knob 64 coaxially connected to the transmission gear 65 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 third ball head 662 is set in the positioning groove of the transmission gear 65 and is pressed and fixed by the second adjustment knob 64. The inner peripheral wall of the mounting cover 901 is provided with multiple arc-shaped grooves, so that the transmission gear 65 and the second adjustment knob 64 are limited by the cooperation of the third ball head 662 and the multiple arc-shaped grooves, ensuring that the second adjustment knob 64 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.
[0145] It is understood that 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. For details, please refer to the relevant description in the first embodiment, which will not be repeated here.
[0146] 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 structures, such as an energy storage battery, etc., which are not limited or elaborated upon. 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. The bearings on any shaft can be fitted with corresponding mounting seats as needed to install the bearings on the shafts. For example, such as... Figure 3As shown, the housing 900 may also include a first fixed seat 905 and a second fixed seat 907. The first fixed seat 905 and the second fixed seat 907 are located at opposite ends of the adjusting shaft 5 in the axial direction, so as to install the bearings on the two threaded sleeves 61 respectively. This will not be described in detail.
[0147] 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.
[0148] 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.
