[0045] See Figures 1-7 This application provides a ball massage device, including a housing 100, a drive unit 200, and a rotating unit 300. The rotating unit 300 includes a rotating shaft 301, a connecting member, and a plurality of balls 302. The connecting member is fixedly connected to the rotating shaft 301, and the balls 302 are connected to the connecting member. The rotating shaft 301 is detachably connected to the drive unit 200, which drives the rotating shaft 301 to rotate. The housing 100 is cylindrical, and a first end of the housing 100 is connected to a first end of the rotating shaft 301. A second end of the rotating shaft 301 is connected to the drive unit 200, and a second end of the housing 100 is connected to the drive unit 200. An opening is provided in the cylindrical wall of the housing 100, and when the rotating shaft 301 rotates, the plurality of balls 302 protrude from the opening in sequence.

[0046] Specifically, the drive unit 200 can be a drive motor, and a coupling is provided between the main shaft of the drive motor and the rotating shaft 301 to realize the rotation of the rotating shaft 301.

[0047] Specifically, the cylindrical housing 100 of this application encloses the rotating shaft 301 and the ball bearings 302. Power transmission is achieved through the connection between the drive unit 200 and the rotating shaft 301. Multiple ball bearings 302 are arranged on a connector to form a ball bearing assembly. The rotating shaft 301 carries multiple ball bearing assemblies by fixing multiple connectors. When the rotating shaft 301 rotates, the multiple ball bearing assemblies rotate, and the ball bearings 302 periodically protrude at the opening of the housing 100 to form massage contact points. The detachable connection between the rotating shaft 301 and the drive unit 200 adopts a standardized plug-in interface, ensuring the stability of power transmission while enabling physical separation.

[0048] The ball massage device provided by this utility model has a detachable connection between the rotating shaft 301 of the rotating part 300 and the driving part 200 during use. When the rotating shaft 301 is connected to the driving part 200, the driving part 200 is activated to make the rotating shaft 301 rotate at a set speed. The user aligns the opening of the housing 100 with the target muscle area, and some of the balls 302 protrude from the opening to produce a kneading and pressing effect on the target muscle area. By changing the number, size and shape of the balls 302 of the rotating part 300, the rotating part 300 of the ball massage device can be quickly switched in conjunction with the detachable connection of the rotating shaft 301. That is, it can quickly replace the different roller modules, thereby expanding the application range of the device and improving the flexibility of the massage device.

[0049] To optimize the above technical solution, the rotating part 300 includes a first fixing member 303 and a second fixing member 304 arranged opposite to each other. The connecting member is arranged parallel to the rotating shaft 301, and there are multiple connecting members arranged around the rotating shaft 301. Multiple rolling balls 302 are connected in series on one connecting member. The first end of the connecting member is fixedly connected to the first fixing member 303, and the second end of the connecting member is fixedly connected to the second fixing member 304. The first fixing member 303 and the second fixing member 304 are fixedly connected to the rotating shaft 301.

[0050] Specifically, the first fixing member 303 and the second fixing member 304 form a rigid support frame for the rotating part 300. Multiple parallel connecting members are evenly distributed around the rotating shaft 301. Each connecting member is connected in series with multiple rolling balls 302 to form an independent massage unit, namely the above-mentioned rolling ball assembly. The first fixing member 303 and the second fixing member 304 form an interference fit with the rotating shaft 301 to ensure the overall structural stability.

[0051] Specifically, the two ends of the connector can be plugged into the first fixing member 303 and the second fixing member 304 respectively, that is, slots are set at the preset positions of the first fixing member 303 and the second fixing member 304, and the two ends of the connector are inserted into the slots to form a fixation.

[0052] In use, the rotating shaft 301 rotates around its own axis, driving the connecting parts to rotate. Multiple connecting parts and the rollers 302 arranged on them protrude sequentially from the opening, thereby massaging the preset parts of the human body. Operators can select different numbers of connecting parts with different numbers of rollers 302 according to the required massage intensity, and can also adjust the massage coverage density by increasing or decreasing the number of connecting parts, thereby improving the flexibility of the massage equipment.

[0053] It should be noted that in order to ensure that the ball 302 can protrude from the opening, the shaft 301 is offset from the axis of the housing 100 and arranged close to the opening. By arranging the first fixing member 303 and the second fixing member 304, the load of the ball 302 can be evenly transmitted to the shaft 301, reducing eccentric vibration.

[0054] Furthermore, operators can replace individual connectors when they are damaged, thereby extending the lifespan of the ball massager.

[0055] It should be noted that the ball 302 is configured such that the distance from the edge of the ball 302 away from the axis of the housing 100 to the axis of the housing 100 is greater than the radius of the housing 100.

[0056] To optimize the above technical solution, a first mounting hole is provided in the middle of the first fixing member 303, and the rotating shaft 301 cooperates with the first mounting hole. The edge of the first fixing member 303 is provided with a first protrusion and a first recess distributed at intervals. A second mounting hole is provided in the middle of the second fixing member 304, and the rotating shaft 301 cooperates with the second mounting hole. The edge of the second fixing member 304 is provided with a second protrusion 305 and a second recess 306 distributed at intervals. A connecting member is connected between the first protrusion and the second recess 306, and a connecting member is connected between the second protrusion 305 and the first recess.

[0057] Specifically, the first fixing member 303 and the second fixing member 304 adopt a complementary concave-convex structure. The asymmetrical distribution of multiple connectors and ball bearings 302 is achieved through the staggered interlocking of the convex and concave parts. The positions of the first mounting hole and the second mounting hole correspond to ensure the concentricity of the rotating shaft 301. The distance between the first convex part and the second concave part 306 matches the length of the connector, and the distance between the second convex part 305 and the first concave part matches the length of the connector, thereby forming a self-locking effect and improving the stability of the structure.

[0058] Specifically, the connector adopts a universal connection structure with the first fixing member 303 and the second fixing member 304 to facilitate installation and replacement. However, the number, size and shape of the rolling balls 302 on different connectors can be changed to form different massage effects and improve the flexibility of the massage device.

[0059] To optimize the above technical solution, the outer surface of the rolling ball 302 is a smooth surface;

[0060] The outer surface of the ball 302 is provided with a plurality of protrusions 3021.

[0061] Specifically, in the ball 302 connected to the connector, the ball 302 can be entirely smooth, or it can be entirely a surface with protrusions 3021. Alternatively, the ball 302 can be partially smooth and partially a surface with protrusions 3021. Under this structure, by changing the rotation direction and speed of the main shaft of the drive motor, the two massage modes can be quickly switched.

[0062] Specifically, multiple protrusions 3021 are evenly distributed on the surface of the rolling ball 302.

[0063] Specifically, protrusion 3021 can be a hemispherical protrusion.

[0064] Specifically, operators can adjust the stimulation effect of the rolling ball 302 on acupoints by selecting protrusions 3021 of different heights.

[0065] To optimize the above technical solution, the ball massage device also includes a limiting part 400, which is slidably engaged with the inner wall of the first end of the housing 100, and the limiting part 400 is provided with a third mounting hole in the middle, the position of the third mounting hole corresponding to the position of the first mounting hole, and the third mounting hole is connected to the first end of the rotating shaft 301.

[0066] Specifically, the first end of the rotating shaft 301 is connected to the first mounting hole and the third mounting hole in sequence, and the rotating shaft 301 can rotate inside the third mounting hole.

[0067] In some embodiments, the inner wall of the housing 100 may be provided with a guide groove, and the limiting part 400 may be provided with a guide rail. When the guide rail slides inside the guide groove, the limiting part 400 slides relative to the housing 100 until it abuts against a preset position inside the housing 100.

[0068] In other embodiments, the inner wall of the housing 100 is provided with an annular step, and the limiting part 400 is in the shape of a hollow cylinder, with its outer wall fitting against the inner wall of the housing 100 until the limiting part 400 engages with the annular step, thereby achieving its limiting.

[0069] When it is necessary to replace the rotating part 300, the operator removes the limiting part 400 so that the first end of the housing 100 is connected to the outside. Then, the rotating part 300 is taken out along the axial direction of the housing 100, the rotating part 300 is replaced, the rotating shaft 301 of the rotating part 300 is connected to the driving part 200, the limiting part 400 is reinstalled, and the driving part 200 is started.

[0070] This arrangement enables rapid switching of the aforementioned ball components, allowing operators to adjust the shape of the ball components of the ball massage device in real time according to the needs of the massage area and intensity, thus expanding the applicability of the device while ensuring its structural stability.

[0071] To optimize the above technical solution, the ball massage device also includes a top cover 500 and buckles. The top cover 500 has a limiting hole, and all buckles are connected to the limiting hole. The top cover 500 is detachably connected to the first end of the housing 100 through the buckles. The first end of the housing 100 has a through hole for connecting the buckles.

[0072] Specifically, the top cover 500 is used to close the first end of the housing 100. When it is necessary to replace the rotating part 300, the top cover 500, the limiting part 400 and the rotating part 300 need to be removed respectively, and the rotating part 300, the limiting part 400 and the top cover 500 need to be reinstalled.

[0073] Specifically, the end of the top cover 500 away from the housing 100 is closed, and the end closer to the housing 100 is connected to the first end of the housing 100.

[0074] Specifically, the top cover 500 includes a cylindrical outer wall 502 and a cap 501 connected to one end of the cylindrical outer wall 502. A limiting hole is opened in the cylindrical outer wall 502. The limiting hole is used to connect to and limit the buckle, so that it can slide along the axial direction of the limiting hole.

[0075] In some embodiments, the buckle is an elastic protrusion. When the operator presses the buckle, the buckle moves in a direction close to the center of the top cover 500, and the top cover 500 moves in a direction close to the housing 100 until the elastic protrusion is engaged with the through hole. Then the elastic protrusion is released to complete the relative fixation of the top cover 500 and the housing 100. At this time, the limiting part 400 is located inside the housing 100.

[0076] In other embodiments, the buckle includes a pressing part 600, an elastic element, and a hook 601. The pressing part 600 is slidably connected to the limiting hole. The elastic element is connected to the pressing part 600 and can extend and retract radially along the top cover 500. The hook 601 is connected to the side of the pressing part 600 near the housing 100, and the edge of the hook 601 extends in a direction away from the rotating shaft 301. When the pressing part 600 is in a pressed state, the elastic element is in a compressed state, and the hook 601 can move axially along the housing 100. When the pressing part 600 is in a relaxed state, the elastic element is in a relaxed state, and the hook 601 is engaged with the through hole.

[0077] Specifically, when the operator presses the pressing part 600, the elastic element changes from a relaxed state to a compressed state, and the hook 601 moves with the pressing part 600 towards the axis of the housing 100. The hook 601 enters the housing 100 until it reaches the preset position. When the operator stops pressing the pressing part 600, the elastic element changes from a compressed state to a relaxed state, and the hook 601 hooks the through hole, thus completing the relative fixation of the top cover 500 and the housing 100.

[0078] This arrangement allows the top cover 500 to be easily and detachably connected to the housing 100, which on the one hand improves the structural stability of the ball massage device, and on the other hand makes it easier to replace the rotating part 300, thus improving the flexibility of the ball massage device.

[0079] To optimize the above technical solution, the ball massage device also includes a control unit 700, which is disposed on the outer wall of the housing 100 and is electrically connected to the drive unit 200. The control unit 700 includes a forward rotation button, a reverse rotation button, a power switch button, and a speed adjustment button.

[0080] Specifically, the housing 100 is provided with a rectangular boss for accommodating the control circuit board of the control unit 700.

[0081] Specifically, the forward button controls the drive motor to rotate forward, the reverse button controls the drive motor to rotate in reverse, the switch button is used to turn the drive motor on and off, and the speed adjustment button is used to adjust the motor speed, which can be adjusted in multiple speed levels.

[0082] Furthermore, the speed adjustment button can be replaced with a knob design.

[0083] To optimize the above technical solution, the ball massage device also includes a display unit 800, which is disposed on the outer wall of the housing 100 and is electrically connected to the control unit 700. The display unit 800 is used to display the forward rotation information, reverse rotation information, switch information and speed information of the drive unit 200.

[0084] Specifically, the display unit 800 is a display screen that can display the forward and reverse rotation status of the drive motor in real time (rotation arrow), as well as information such as rotation speed, battery percentage or numerical icons, so that the operator can intuitively obtain the usage information of the ball massage device, thereby improving the ease of use of the ball massage device.

[0085] To optimize the above technical solution, a handle 900 is installed on the side of the top cover 500 away from the housing 100.

[0086] Specifically, the two ends of the handle 900 are fixedly connected to the cylindrical outer wall 502 of the top cover 500. By arranging the handle 900, the mobility of the ball massage device can be improved.
