[0030] The following describes the present utility model in detail with reference to the accompanying drawings.

[0031] As Figures 1-4 shown, the electro - stimulation therapeutic instrument includes a fixed cover 1 and a drive cover 11 that is movably matched with the fixed cover 1. The fixed cover 1 and the drive cover 11 cooperate to form a drive cavity, and a functional component is arranged in the drive cavity. The functional component includes a control structure. The control structure includes an encoder 12 arranged in the drive cavity. The input end of the encoder 12 is connected to a rotatable driven member. A transmission structure is arranged between the driven member and the drive cover 11. The drive cover 11 rotates to drive the driven member to rotate so as to drive the encoder 12 to output a pulse signal.

[0032] During use, rotate the drive cover 11 to rotate left or right. Drive the driven member to rotate through the transmission structure. The driven member drives the encoder 12 to output a pulse signal to achieve the control of different gear adjustments. When the transmission structure cooperates with the driven member, a feedback effect will be generated, and the gear adjustment can be clearly understood without virtual position. When used on the shoulders, back and other parts, blind operation can be carried out for control to improve the control accuracy.

[0033] Specifically, the follower includes a follower gear 13 installed at the input end of the encoder 12. The forward and reverse rotations of the follower gear 13 can drive the input to the encoder 12. The encoder 12 outputs different pulse signals correspondingly according to the forward and reverse rotations, and the pulse signals are used to control the circuit path.

[0034] Preferably, the transmission structure includes a toothed groove 14 arranged on the driving cover 11. The toothed groove 14 meshes with the follower gear 13 for transmission. When the driving cover 11 is rotated, the toothed groove 14 will mesh with the follower gear 13 for transmission. During transmission, the follower gear 13 rotates. Correspondingly, the input end of the encoder 12 will rotate, and the encoder 12 outputs different pulse signals correspondingly according to the forward and reverse rotations, and the pulse signals are used to control the circuit path.

[0035] Preferably, the toothed groove 14 is arranged along the inner wall of the driving cover 11 for one week. When the driving cover 11 rotates, it can rotate one week. No matter what the rotation angle is, the follower gear 13 can still be kept rotating, that is, the input end of the encoder 12 will rotate to output pulse signals.

[0036] Preferably, a balance gear 15 meshing with the toothed groove 14 is further arranged in the driving cavity. The follower gear 13 and the balance gear 15 are simultaneously meshed with the toothed groove 14 for transmission. Therefore, when the driving cover 11 rotates, it always maintains transmission with the follower gear 13 and the balance gear 15, which can improve the rotation stability of the driving cover 11, and the feedback effect during rotation is further improved.

[0037] Preferably, the number of the balance gears 15 can be one or more. The multiple balance gears 15 can further increase the rotation stability of the driving cover 11 during rotation and further increase the transmission stability.

[0038] The functional component includes a driving bracket 2 installed on the fixed cover 1. The functional main board 21 is installed on the driving bracket 2. The driving bracket 2 is installed with a limiting ring 16. An annular groove 17 slidably matched with the limiting ring 16 is formed around the inner wall of the inner ring of the driving cover 11. When the driving cover 11 rotates, the annular groove 17 formed on the driving cover 11 slidably matches with the limiting ring 16 of the driving bracket 2, which can prevent the driving cover 11 from axially moving, ensure the movable connection with the fixed cover 1, and the toothed groove 14 maintains meshing transmission with both the follower gear 13 and the balance gear 15, improving the rotation stability.

[0039] Furthermore, an inner groove 18 is formed around the end face of the driving cover 11, and a convex ring 19 coaxially matched with the inner groove 18 is formed by the convexity of the end face of the fixed cover 1. When the driving cover 11 rotates, the inner groove 18 formed on the end face of the driving cover 11 can slidably match with the convex ring 19 on the end face of the fixed cover 1; this enables the fixed cover 1 and the driving cover 11 to be coaxially aligned, which can further improve their rotation stability and enable the toothed groove 14 to maintain meshing transmission with both the follower gear 13 and the balance gear 15.

[0040] The functional components further include a functional main board 21 installed on the driving bracket 2. The functional main board 21 is installed with a pressable opening and closing switch 22. The fixed cover 1 is formed with a switch slot 23 for installing the opening and closing switch 22. The outer end of the opening and closing switch 22 passes through the switch slot 23 and is exposed outward. When it needs to be started, pressing the opening and closing switch 22 can start it, and pressing the opening and closing switch 22 again can close it.

[0041] The driving cover 11 is formed with a through opening structure 24 away from the fixed cover 1. The opening structure 24 is installed with a display component 25. The display component 25 is installed on the driving bracket 2, and the display component 25 can be used to display the current gear and working conditions.

[0042] Preferably, the display structure includes a display screen.

[0043] The functional main board 21 is also installed with a connecting female socket 26. The fixed cover 1 is formed with a driving port 27 for installing the connecting female socket 26. The connecting female socket 26 passes through the driving port 27 and projects outward; during operation, this product is used in combination with different electrode patches 28. When using, stick the required electrode patch 28 on the treatment site and then make it portable. The electrode patch 28 is connected to the connecting female socket 26, and after being powered on, treatment is carried out. This product is generally used in combination with a charging bin, which can increase the battery life and storage function of the product.

[0044] Preferably, the electrode patch 28 is installed with a magnetic male socket, and the connecting female socket 26 is a magnetic female socket. The electrode patch 28 can be magnetically connected to the magnetic female socket through the magnetic male socket, realizing magnetic connection and facilitating disassembly.

[0045] The encoder 12 is installed on the functional main board 21. The upper surface of the functional main board 21 is electrically connected with an electromagnetic coil control module, an electrical stimulation module, an electromyogram detection module, a reed switch, and a control chip. The reed switch includes a first reed switch and a second reed switch. The first reed switch is connected to the control end of the electrical stimulation module, and the second reed switch is electrically connected to the control end of the electromyogram detection module. A group of electromagnetic coils are wound outside both the first reed switch and the second reed switch; the control chip is electrically connected to the control end of the electromagnetic coil control module, the encoder 12 is electrically connected to the control chip, and the electromagnetic coil control module is electrically connected to the control ends of the electromagnetic coils on the two reed switches. The electromagnetic coil control module controls the opening and closing of the first reed switch or the second reed switch by controlling the energization and de-energization of the electromagnetic coils.

[0046] The model of the control chip is ESP32. After the control chip receives the pulse signal of the encoder 12, combined with the click determination signal of the opening and closing switch 22, then the control chip starts to control the electromagnetic coil control module to form a path for the reed switch corresponding to the electromyogram detection module or the electrical stimulation module.

[0047] Furthermore, the functional main board 21 is snap-connected to the inner wall of the fixed cover 1. The driving bracket 2 is provided with a battery pack. The functional main board 21 is electrically connected to a display connection seat, a battery connection seat, and a Bluetooth module. The display connection seat is connected to the wire board, and the display connection seat is electrically connected to the display through the wire board. The battery connection seat is fixed and electrically connected to the battery pack.

[0048] Preferably, the display is an LCD display, which can display treatment modes, treatment times, treatment gears, Bluetooth identifiers, etc. By setting up the Bluetooth module, this product can not only adjust the gears by rotating the driving cover 11, but also be connected to a mobile phone via Bluetooth and use the APP to select treatment times, treatment gears, etc.

[0049] The LCD display is used to better display more content. Compared with the traditional digital tube method, the content is clear and can also be updated via OTA of the program to modify to richer content at any time.

[0050] When in use, long-press the opening and closing switch 22, and then rotate the rotating driving cover 11 to switch the mode. If the electrical stimulation function is selected, when the rotating driving cover 11 rotates, the ratchet groove 14 will mesh with the driven gear 13 for transmission. During transmission, the driven gear 13 rotates. Correspondingly, the input end of the encoder 12 will rotate. The encoder 12 outputs different pulse signals according to forward and reverse rotations. The pulse signals are transmitted to the control chip of the functional main board 21. The control chip transmits the signal to the electromagnetic coil control module. The electromagnetic coil control module selects to control the electromagnetic coil on the first reed switch to be energized. After the electromagnetic coil is energized, an electromagnetic field is formed, causing the two adjacent metal reed pieces inside the reed switch to be attracted and energized, and then the treatment module corresponding to the reed switch starts to work. The treatment module controls the electrode piece 28 through the magnetic snap connection female seat 26 on the bottom surface of the functional main board 21 and the connection male seat 29 on the corresponding electrode piece 28. The functional main board 21 is essentially a circuit board. Rotate the rotating driving cover 11 to adjust to a comfortable gear. Rotating left and right realizes different signals, thus realizing gear addition and subtraction, and realizing the function of blind operation where people can't see. Generally speaking, the specific situations of mode switching and gear addition and subtraction may need to cooperate with the APP to display the specific situation more clearly.

[0051] It should be noted that by replacing different styles and types of electrode pieces 28 for this product, it can be used on different parts of the body according to needs, further improving the practicality.

[0052] In summary, it can be seen that the present utility model has the above-mentioned excellent characteristics, enabling it to enhance the efficiency that has never existed in the prior art during use and having practicality, becoming a product with extremely high practical value.

[0053] The above content is only a preferred embodiment of the present utility model. For those of ordinary skill in the art, based on the idea of the present utility model, there will be changes in the specific implementation manner and application scope. The content of this specification should not be construed as a limitation to the present utility model.
