[0033] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses consistent with some aspects of this disclosure as detailed in the appended claims.

[0034] Please refer to the instruction manual appendix. Figures 1-7 This utility model discloses a rhythmic massager, which mainly includes an upper cover assembly, a drive assembly, and a lower cover assembly. The upper cover assembly includes a handle cover 1 and a main body cover 2 that fastens to it. The handle cover 1 contains a control module that controls the operation of the entire device. The control module includes a screen panel 8, a roller circuit board 9, a main control board 10, and a charging board 11 that are electrically connected in sequence. The handle cover 1 also has a toggle switch 30, which can control the start and stop of the device by operating the toggle switch 30. The main control board 10 is electrically connected to a speaker 12. The roller circuit board 9 has a roller 13, and the roller 13 has a light guide column 15 for use with it. The main control board 10 has a button 16 that drives the main control board 10 by pressing it, which can be used for mode selection or other control operations. The handle cover 1 has slots for accommodating the screen 14, the light guide column 15, and the button 16. When in use, turn on the toggle switch 30 and the device will start. By turning the roller 13, a signal can be transmitted to the main control board 10 through the roller circuit board 9, thereby controlling the vibration amplitude of the device. The vibration amplitude information will be reflected on the screen 14 through the screen panel 8, and the speaker 12 will emit a buzzer signal. Based on the operation feedback, when the device is out of power, it can be charged through the charging interface on the charging board 11.

[0035] The lower cover assembly includes a lower cover 7, which forms a cavity with the upper cover 2 to accommodate the drive assembly. The lower cover 7 also has two strap buckles 24, which face each other and engage between the upper cover 2 and the lower cover 7. The line connecting the two strap buckles 24 is perpendicular to the axis of the output shaft of the motor 5, and both strap buckles 24 extend outside the device.

[0036] Meanwhile, a decorative screw ring 25 is fixedly connected to the bottom periphery of the lower cover 7 of the main body. Two opposing electrode plates 26 are provided at the bottom of the lower cover 7 of the main body, and a cavity is formed between the electrode plates 26 and the lower cover 7 of the main body. A heating film 27 is provided in the cavity. A physiotherapy cover 28 is also provided below the lower cover 7 of the main body. A physiotherapy lamp plate 29 is provided inside the physiotherapy cover 28. A slot for accommodating the physiotherapy lamp plate 29 is opened below the lower cover 7 of the main body. The physiotherapy lamp plate 29 and the heating film 27 are used in conjunction with the control module and are controlled by the control module. The physiotherapy lamp plate 29 emits light with a physiotherapy frequency, and the heating film 27 can be heated according to the control module. During the vibration operation of the device, it assists in physiotherapy and achieves a better massage effect.

[0037] The aforementioned components are all auxiliary components. As the core component of this utility model, the composition of the drive component is crucial. In a preferred embodiment of this utility model, the control module is mainly used to drive the drive component to operate. The drive component includes a core assembly 3 and a battery 4. The battery 4 supplies power to the core assembly 3. The core assembly 3 includes a motor 5 and an eccentric block 6, and also includes motor shock absorber sleeves 17 disposed on both sides of the motor 5. The motor shock absorber sleeves 17 are made of silicone material and are used to buffer vibrations based on amplitude during equipment operation. A small pulley 18 is fixedly connected to the output shaft of the motor 5; a large pulley is fixedly connected to the side of the eccentric block 6 near the output shaft of the motor 5. 19. Both the small pulley 18 and the large pulley 19 are straight-toothed. They are connected by a synchronous belt 20, which has grooves. The straight teeth of the small and large pulleys 18 engage within these grooves. The small pulley 18 drives the large pulley 18 to rotate, which in turn drives the eccentric block 6 to rotate. The eccentric block 6 is made using a one-piece molding process; it is half solid and half hollow, creating an unbalanced force. Therefore, during the rotation of the eccentric block 6, as it rotates around its central axis, its center of mass is not located on the axis of rotation, resulting in periodic centrifugal force. This centrifugal force changes direction continuously with the rotation of the eccentric block, producing a regular rhythmic vibration effect, thus achieving a massage effect.

[0038] Next, bearings 21 are provided on both sides of the eccentric block 6. The bearings 21 are fixedly connected to the side walls of the large pulley 19 and the eccentric block 6, respectively. Bearing damping sleeve 1 22 and bearing damping sleeve 23 are respectively provided inside and outside the bearings 21. Bearing damping sleeve 23 and motor 5 are both snapped into the cavity formed by pressing the upper cover 2 and the lower cover 7 of the main body. Bearing damping sleeve 1 22 and bearing damping sleeve 23 are also made of silicone material. Through the use of bearing damping sleeve 1 22 and bearing damping sleeve 23, the bearing 21 can have a shock absorption and buffering effect during operation.

[0039] To maximize the vibration effect while minimizing the device's size, the small pulley 18 has a tooth tip circle diameter between 7 and 20 mm, preferably 38.3 mm and / or 36.92 mm; the large pulley 19 has a tooth tip circle diameter between 20 and 50 mm, preferably 9.75 mm and 11.13 mm; the transmission ratio between the large pulley 19 and the small pulley 18 via the synchronous belt 20 is between 2 and 4; simultaneously, the center distance between the eccentric block 6 and the motor 5 is 30 to 60 mm, the center distance between the battery 4 and the eccentric block 6 is 25 to 55 mm, the outer diameter of the eccentric block 6 is 25 to 50 mm, and the weight of the eccentric portion of the eccentric block 6 is 120 to 210 g; with these dimensions, the device can maintain the same vibration intensity as existing technologies while minimizing internal space occupation, thus reducing the size and weight of the device for easy portability.

[0040] It should be noted that all electrical components mentioned in this article are connected to an external main controller and 220V AC mains power. The main controller can be a conventional known device such as a computer. The specific implementation of this disclosure omits detailed descriptions of known functions and components. To ensure device compatibility, the operating methods used are consistent with the parameters of commercially available instruments.

[0041] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
