The first ball assembly 10 can massage in a telescopic manner and a rotational manner at the same time, and the second ball assembly 40 can also massage in a telescopic manner. In this way, the massager 100 can provide users with multiple massage methods and has a better massage effect.

[0054] In order to increase the aesthetics and safety of the massager 100, the massager further comprises a protective member that wraps the first ball assembly 10, the transmission assembly 20, and the driving member 30. The protective member may be made of cloth, silicone, or rubber.

[0055] The first ball assembly 10 may further include a mounting member 12 for mounting the first ball 11, and a connecting member 13 disposed on the mounting member 12. The mounting member 12 includes a first mounting portion 121, a second mounting portion 122 disposed opposite to the first mounting portion 121, and at least one third mounting portion 123 mounted between the first mounting portion 121 and the second mounting portion 122. The first mounting portion 121 and the second mounting portion 122 may be regular or irregular plate-shaped or disc-shaped structures, and the third mounting portion 123 may be a rod-shaped, column-shaped, hook-shaped, arc-shaped structure, etc. The present invention does not limit the shapes of the first mounting portion 121, the second mounting portion 122 and the third mounting portion 123, which can be suitable for actual needs. An installation space (not shown) is formed between the first mounting portion 121 and the second mounting portion 122, and the third mounting portion 123 can be accommodated in the installation space and installed between the first mounting portion 121 and the second mounting portion 122. The number of the third mounting parts 123 can be multiple. The utility model does not limit the number and length of the third mounting parts 123, and it can be suitable for actual needs. The number of the first balls 11 can be multiple, each first ball 11 is provided with a through hole 111, and at least one first ball 11 can be sleeved on each third mounting part 123, and the first ball 11 can rotate around the third mounting part 123. The length of the third mounting part 123 can be greater than the diameter of the first ball 11 installed thereon or greater than the sum of the diameters of several first balls 11 installed thereon. The number of first balls 11 arranged on each third mounting part 123 can be the same or different. When multiple first balls 11 are arranged on each third mounting part 123, the massage range of the first ball assembly 10 is larger and the massage effect is better. The material of the first ball 11 can be silicone, plastic, metal, plastic, or wood. The two ends of the third mounting portion 123 may be disposed at the edge regions of the first mounting portion 121 and the second mounting portion 122, so that the first ball 11 may at least partially protrude from the first mounting portion 121 and the second mounting portion 122. Thus, when the first ball 11 rotates around the third mounting portion 123, muscle soreness may be relieved, and the back, head, shoulders, neck, hands, legs, waist, abdomen, feet and other parts may be effectively massaged.

[0056] The first mounting portion 121 and the second mounting portion 122 may be specifically circular, elliptical, polygonal, etc. In this embodiment, a hexagon is used as an example for description. The first mounting portion 121 and the second mounting portion 122 both include a side 1211 and a protrusion 1212, and the protrusion 1212 is a connecting portion of adjacent side 1211. It can be understood that when the first mounting portion 121 and the second mounting portion 122 are hexagonal, the protrusion 1212 is the portion of the first mounting portion 121 and the second mounting portion 122 that protrudes outward the most, and the first ball 11 can be arranged to protrude from the protrusion 1212.

[0057] The connecting member 13 includes a connecting portion 131 and a connecting portion 132 connected to each other. The connecting portion 131 protrudes from the first mounting portion 121 and is connected to the transmission assembly 20. The connecting portion 132 protrudes from the second mounting portion 122 and is connected to the vibration assembly 50 of the massager 100. When the first ball assembly 10 performs telescopic movement and rotational movement, it can drive the vibration assembly 50 to perform telescopic movement and rotational movement. In this way, when the vibration assembly 50 vibrates, it can also perform telescopic movement and rotational movement, providing users with a variety of massage methods. The central area of ​​the first mounting portion 121 and the second mounting portion 122 is also provided with a mounting hole 1213, and the connecting portion 131 and the connecting portion 132 can be accommodated in the corresponding mounting hole 1213. In one embodiment, the first mounting portion 121, the second mounting portion 122, the third mounting portion 123, the connecting portion 131, and the connecting portion 132 can be integrally formed, or they can be formed separately and then connected.

[0058] The transmission assembly 20 includes a fixed frame 21, a gear set 22 connected to the driving member 30, a rotating member 23 connected to the gear set 22 and the first ball assembly 10, and a fixed member 24 fixed to the fixed frame 21. The outer surface of the rotating member 23 is provided with at least one guide groove 231 which is spirally or obliquely arranged. The guide groove 231 is a closed groove arranged along the axial direction of the rotating member 23, and includes a low point close to the driving member 30 and a high point away from the driving member 30. The fixing member 24 is slidably accommodated in the guide groove 231. When the driving member 30 drives the gear set 22 to rotate, the rotating member 23 rotates together, and drives the first ball assembly 10 and the vibration assembly 50 to rotate; the fixing member 24 is abutted against the groove wall of the guide groove 231 and interacts with the groove wall of the guide groove 231 and slides between the low point and the high point of the guide groove 231. Since the fixing member 24 is fixed on the fixing frame 21, the fixing member 24 and the guide groove 231 interact with each other so that the rotating member 23 moves up and down relative to the fixing member 24 while rotating, and drives the first ball assembly 10 and the vibration assembly 50 to telescopic movement, so as to provide a variety of massage methods.

[0059] The fixing frame 21 includes a first fixing portion 211, a second fixing portion 212 arranged opposite to the first fixing portion 211, a third fixing portion 213 arranged opposite to the second fixing portion 212, a receiving portion 214 arranged on the third fixing portion 213, at least one guiding portion 215, and a fixing portion 216 fixedly arranged outside the receiving portion 214 for receiving the fixing member 24. The first fixing portion 211, the second fixing portion 212, and the third fixing portion 213 are generally in a disc-shaped structure, the guiding portion 215 is generally in a rod-shaped structure, and the receiving portion 214 is generally in a barrel-shaped structure. The utility model does not limit the shapes of the above-mentioned components, which can be suitable for actual needs. One end of the guiding portion 215 is connected to the first fixing portion 211, and the other end of the guiding portion 215 is connected to the third fixing portion 213. The second fixing portion 212 is fixedly sleeved on the guiding portion 215 and arranged adjacent to the first fixing portion 211. The second ball assembly 40 can be slidably mounted on the guide portion 215 and located between the second fixing portion 212 and the third fixing portion 213. The number of the guide portions 215 can be multiple. In the present embodiment, the number of the guide portions 215 is two, both of which can be rod-shaped structures and are arranged at intervals. The surface (not shown) on which the fixing portion 216 is connected to the accommodating portion 214 is adapted to the outer surface of the accommodating portion 214, so that the fixing portion 216 can be stably connected to the accommodating portion 214, the opening 2161 of the fixing portion 216 and the opening 2144 of the accommodating portion 214 are aligned and connected, the fixing member 24 is fixedly accommodated in the opening 2161 and the opening 2144, and the portion of the fixing member 24 extending out of the opening 2161 and the opening 2144 can extend into the guide groove 231. The fixing portion 216 can increase the stability of the fixing member 24, and prevent the fixing member 24 from being hit by the groove wall of the guide groove 231 and falling off from the receiving portion 214. The fixing portion 216 and the receiving portion 214 can be integrally formed, or can be separately formed and then connected.

[0060] The gear set 22 includes a first gear 221 connected to the output shaft 31 of the driving member 30, a second gear 222 meshing with the first gear 221, and a third gear 223 meshing with the second gear 222 and connected to the rotating member 23. When the rotating member 23 moves up and down relative to the fixed member 24, the third gear 223 can move up and down on the second gear 222, and the rotating member 23 and the third gear 223 can further drive the second ball assembly 40 to perform telescopic movement.

[0061] A through hole 2111 is provided in the central area of ​​the first fixed part 211. A receiving hole 2211 is provided in the central area of ​​the first gear 221. The receiving hole 2211 may be a through hole, or may only penetrate the lower surface of the first gear 221 without penetrating its upper surface. When the first gear 221 is arranged on the first fixed part 211, the receiving hole 2211 faces the through hole 2111 and is connected to the through hole 2111. At this time, the first gear 221 is also roughly located in the central area of ​​the first fixed part 211. The driving member 30 may be located below the first fixed part 211, or connected to the lower surface of the first fixed part 211. The output shaft 31 of the driving member 30 may rotatably pass through the through hole 2111 and be solidly contained in the receiving hole 2211. In this way, when the driving member 30 is started, the output shaft 31 rotates, which can drive the first gear 221 to rotate together.

[0062] The second gear 222 is disposed on one side of the first gear 221 and meshes with the first gear 221. In one embodiment, the second gear 222 is roughly T-shaped, including a first sub-gear 2221 located on the first fixing portion 211 and a second sub-gear 2222 connected to the first sub-gear 2221, the first sub-gear 2221 is disposed on one side of the first gear 221 and meshes with the first gear 221, the length of the second sub-gear 2222 is greater than the length of the first sub-gear 2221, the first sub-gear 2221 and the second sub-gear 2222 can be an integral structure or a split structure connected together. The length of the gear portion 2225 of the second sub-gear 2222 is not less than the one-way moving distance of the rotating member 23 in the telescopic movement (such as the distance that the rotating member 23 moves from the bottom end to the top end in the telescopic movement), so as to prevent the third gear 223 from being separated from the second sub-gear 2222 during the telescopic movement. One of the first sub-gear 2221 and the second sub-gear 2222 is provided with a receiving hole 2223, and the other of the two is provided with a protrusion 2224, which is received in the receiving hole 2223 to connect the first sub-gear 2221 and the second sub-gear 2222. The first gear 221 is approximately located in the central area of ​​the first fixed portion 211, the first sub-gear 2221 is located on the first gear 221 and meshes with the first gear 221, and the outer edge of the first sub-gear 2221 is at least partially arranged substantially flush with the outer edge of the first fixed portion 211. The second sub-gear 2222 is approximately arranged in the central area of ​​the first sub-gear 2221 and is arranged substantially perpendicular to the first sub-gear 2221 to ensure stable rotation. It can be understood that when the size of the first gear 221 is large enough, the outer edge of the second sub-gear 2222 is arranged substantially flush with the outer edge of the first fixed portion 211, and the second sub-gear 2222 can directly mesh with the first gear 221 without the need to set the first sub-gear 2221.

[0063] The second fixing portion 212 is provided with a through hole 2121, and the through hole 2121 is eccentrically arranged with respect to the through hole 2111. The gear portion 2225 of the second sub-gear 2222 can pass through the through hole 2121 and extend into the accommodation space 2130 between the second fixing portion 212 and the third fixing portion 213, and the third gear 223 and the second ball assembly 40 can also be slidably accommodated in the accommodation space 2130, and the third gear 223 and the second ball assembly 40 can perform telescopic movement and up-and-down movement in the accommodation space 2130.

[0064] A through hole 2131 is provided in the approximate center area of ​​the third fixing portion 213. The accommodating portion 214 is provided with an accommodating cavity 2141, and the accommodating portion 214 is also provided with an upper opening 2142 and a lower opening 2143 which are communicated with the accommodating cavity 2141, and the rotating member 23 can be accommodated in the accommodating cavity 2141. The accommodating portion 214 is located on the third fixing portion 213, and the lower opening 2143 is also communicated with the through hole 2131. The size of the upper end of the rotating member 23 is larger than the size of the upper opening 2142, and the size of the lower end is smaller than the size of the lower opening 2143, so that the rotating member 23 can extend out of the lower opening 2143 but not extend out of the upper opening 2142 during the process of moving up and down.

[0065] The third gear 223 includes a gear portion 2231 and a connecting portion 2232. The size of the gear portion 2231 is larger than the size of the connecting portion 2232. The third gear 223 is also provided with a through hole 2233 that penetrates the gear portion 2231 and the connecting portion 2232. The gear portion 2231 meshes with the gear portion 2225 of the second sub-gear 2222, and the gear portion 2225 is axially connected to the gear portion 2225 (see FIG. Fig.13 The connecting portion 2232 includes two oppositely disposed straight surfaces 2234 and two oppositely disposed curved surfaces 2235, and the two straight surfaces 2234 and the curved surfaces 2235 are alternately connected.

[0066] The rotating member 23 is generally in a rod-shaped structure and is provided with a through hole 232. A connecting portion 233 is convexly provided at one end of the rotating portion 230 of the rotating member 23 near the third gear 223. The through hole 232 penetrates the rotating portion 230 and the connecting portion 233. The size of the rotating portion 230 is larger than that of the connecting portion 233. The connecting portion 233 of the rotating member 23 is connected to the connecting portion 2232 of the third gear 223 to connect the rotating member 23 with the third gear 223. The connecting portion 233 is provided with a receiving groove 2331. The through hole 232 penetrates the bottom wall of the receiving groove 2331. The groove wall of the receiving groove 2331 includes two oppositely arranged straight surfaces 2332 and two oppositely arranged arc surfaces 2333. When the connecting portion 2232 is accommodated in the receiving groove 2331, the straight surface 2234 corresponds to the straight surface 2332, and the arc surface 2235 corresponds to the arc surface 2333, so as to ensure the stability of the connection between the connecting portion 2232 and the connecting portion 233. When the connecting portion 2232 is received in the connecting portion 233, the through hole 2233 of the third gear 223 is connected to the through hole 232 of the rotating member 23. Of course, the through hole 232 may not pass through the bottom wall of the receiving groove 2331, the third gear 223 may not have the through hole 2233, or the through hole 2233 of the third gear 223 may not pass through its bottom wall. The through hole can reduce the mass and prevent the massager 100 from being too heavy.

[0067] In one embodiment, the at least one guide groove 231 includes a first guide groove 2311 and a second guide groove 2312 that are connected. The first guide groove 2311 and the second guide groove 2312 are arranged along the longitudinal direction of the rotating member 23 (see Fig.13BB line direction in the middle of the rotating member 23), and the intersection 2313 of the two is roughly the middle area 2310 of the rotating member 23. Specifically, the first guide groove 2311 can extend obliquely from the middle area 2310 of the rotating member 23 on one side of the rotating member 23 to the first end 2314 (i.e., the end close to the driving member 30), and then extend obliquely from the first end 2314 on the other side of the rotating member 23 to the middle area 2310 of the rotating member 23, and the second guide groove 2312 can extend obliquely from the middle area 2310 of the rotating member 23 on one side of the rotating member 23 to the second end 2315 (i.e., the end close to the first ball assembly 10), and then extend obliquely from the second end 2315 on the other side of the rotating member 23 to the middle area 2310 of the rotating member 23. Specifically, the first guide groove 2311 includes a first section guide groove 2316 and a second section guide groove 2317 that are connected. The first section guide groove 2316 and the second section guide groove 2317 are firstly arranged to be inclined away from each other in a direction close to the driving member 30 from the middle area 2310, and then are arranged to be inclined close to each other until they are connected.
