[0022] In order to more clearly and completely illustrate the technical solution of the present invention, the present invention is further described below in conjunction with the accompanying drawings.

[0023] Please refer to Figure 1-Figure 4The present invention proposes a portable muscle stimulator, including a gripping handle 1, a control panel 2 is fixedly installed at one end of the gripping handle 1, and the control panel 2 can be connected to the gripping handle 1 by bolt connection or snap connection to ensure the stability of the installation and facilitate later maintenance; a power supply mechanism 3 is installed on the inner wall of the gripping handle 1, and the power supply mechanism 3 is connected to the inside of the gripping handle 1 by snap connection or embedded connection. This assembly method can ensure its firm installation and facilitate battery replacement. A massage mechanism 4 is installed at one end of the gripping handle 1, and the massage mechanism 4 is fixed to the end of the gripping handle 1 by thread or flange connection to ensure the stability of the massage mechanism 4 under high-frequency vibration. A stimulation mechanism 5 is installed at one end of the massage mechanism 4, and the stimulation mechanism 5 can be fixed to the outside of the massage mechanism 4 by flange connection or snap connection to ensure assembly tightness and facilitate disassembly. The massage mechanism 4 includes a fixed shell 41, and the fixed shell 41 is fixedly installed at one end of the gripping handle 1, and can be fixed by bolts or interference fit to ensure stability during use. A connecting bearing 42 is installed on the surface of the fixed shell 41. The number of the connecting bearings 42 is two. The two connecting bearings 42 are symmetrically distributed on the surface of the fixed shell 41. The symmetrical arrangement of the bearings makes the massage shell 46 stable and symmetrical when moving. The connecting bearing 42 can be a ball bearing or a sliding bearing to ensure the smooth rotation of the massage shell 46 during operation. A vibration motor 43 and two motors 44 are fixedly installed on the inner wall of the fixed shell 41. The vibration motor 43 can be installed on the inner wall of the fixed shell 41 by bolts or flanges to ensure that it will not loosen due to vibration during operation. Gears 45 are installed on the output ends of the two motors 44. The two motors 44 are installed together. The two gears 45 at the output ends of the two motors 44 respectively resist the top and bottom sides of the inner gear ring 48, so that the force can be balanced, so that the massage shell 46 rotates more smoothly. The gear 45 can be connected to the output shaft of the motor 44 by a keyway or a thread to ensure that the gear 45 can be efficiently transmitted when the motor 44 rotates. The surface of the fixed shell 41 is provided with a massage shell 46 through a connecting bearing 42, and an inner sleeve 47 is fixedly installed on the inner wall of the massage shell 46. The inner sleeve 47 is connected to the massage shell 46 by interference fit or threaded connection to ensure concentricity and stability during rotation. An inner toothed ring 48 is fixedly installed on the inner wall of the inner sleeve 47. The inner toothed ring 48 can be fixed inside the inner sleeve 47 by pressing or welding, thereby increasing the meshing accuracy between the gear 45 and the inner toothed ring 48, thereby improving the rotation effect of the massage shell 46. A reserved groove 49 is provided on the surface of the fixed shell 41, and the reserved groove 49 provides enough space for the gear 45 to better mesh with the inner toothed ring 48. The motor 44 drives the gear 45 to rotate, and the meshing of the gear 45 and the inner toothed ring 48 enables the inner toothed ring 48 to rotate accordingly, thereby driving the massage shell 46 and the inner sleeve 47 to rotate together.A plurality of rectangular blocks 410 are fixedly mounted on the surface of the massage housing 46. The rectangular blocks 410 are evenly distributed on the surface of the massage housing 46. A gap of 1-10 mm is left between the rectangular blocks 410. This design increases the friction of the massage surface and reduces the pressure on the skin, which is suitable for massages of different intensities. The rectangular blocks 410 can be made of silicone or soft rubber material to ensure soft contact with the skin during the massage process and avoid discomfort caused by excessive friction.

[0024] The power supply mechanism 3 includes a battery shell 31, which is fixedly mounted on the inner wall of the gripping handle 1 and can be fixed by embedding or snap connection, which is convenient for disassembly and replacement of batteries.

A circuit board 33 is fixedly mounted on the bottom surface of the battery shell 31, and the circuit board 33 is fixed to the battery shell 31 by screws or bonding to facilitate circuit maintenance and battery power supply stability. A speaker 34 is fixedly mounted on the side of the battery shell 31, and the speaker 34 is installed by threading or bonding to ensure clear sound transmission. The stimulation mechanism 5 includes a shell 51, which is a cylindrical structure made of PP plastic with good wear resistance and impact resistance. The shell 51 is fixedly mounted on one end of the fixed shell 41 and can be installed by snaps or bonding to ensure a firm installation. The inner wall of the housing 51 is fixedly mounted with a capacitor 52, which is fixed to the inner wall of the housing 51 by screws or embedded installation, ensuring that the position of the capacitor 52 is stable during the electrical stimulation process. An electrode head 53 is installed at one end of the capacitor 52, and the electrode head 53 is embedded in one end of the housing 51 and fixed by press-fit or interference fit, ensuring that the electrode head 53 can closely contact the skin surface.

[0025] In this embodiment, the user only needs to hold the grip handle 1, and then fit the massage shell 46 to the position that needs massage, and then power the vibration motor 43 and the motor 44 through the battery, and then the vibration motor 43 generates vibration, and the motor 44 can drive the gear 45 to rotate, and the gear 45 can then drive the inner gear ring 48 meshing with it to rotate, and the inner gear ring 48 then drives the inner sleeve 47 and the massage shell 46 to rotate, and at this time, the rectangular block 410 on the surface of the massage shell 46 can rub the skin to perform massage, and through vibration and rotational friction, the massage area can be more stimulated, thereby improving the effect of muscle rehabilitation training. The present invention can provide more comprehensive muscle stimulation by combining the dual mechanisms of vibration and rotation. Vibration helps to relax muscle tissue, and rotational friction can act more deeply on specific muscle areas, thereby enhancing blood circulation and promoting muscle recovery. The user only needs to hold the handle and aim the device at the part that needs massage. The operation is simple and convenient. This design allows users to use it at home or anywhere else without additional operating skills or external force. Since it is battery-powered, users can easily carry this device without being affected by power sockets. The limitations of the device increase the diversity of usage scenarios. At the same time, since the device integrates two mechanisms, vibration and rotation, it can relax and activate muscles at the same time, which is particularly suitable for recovery after exercise or relief of certain chronic muscle pain. The operation of the electrode head 53 can be controlled by the set control panel. During operation, the electrode head 53 is powered by the capacitor 52 to stimulate the skin, which can further improve the effect of muscle rehabilitation training. The massage time can be broadcasted through the speaker 34, so that the user can judge the massage time conveniently. In the present invention, the user can control the operation of the electrode head 53 through the control panel 2. The electrode head 53 is powered by the capacitor 52 and can provide continuous or pulsed current stimulation. This targeted electrical stimulation helps to activate deep muscles and plays an important role in restoring muscle function and promoting blood circulation. The speaker 34 broadcasts the massage time, so that the user can better monitor the duration of treatment or exercise, ensure the efficiency and safety of the massage, and prevent excessive use. The integrated functions make the device more user-friendly. The user can obtain all necessary information and control without additional equipment. Such an integrated design reduces the complexity of operation.
