Description

Technical Field

[0001] This utility model relates to the field of massage therapy technology, and in particular to a scraping device. Background Technology

[0002] Currently, electronic gua sha devices are available on the market. These devices use an air suction device to draw air from the device, creating negative pressure inside. This causes the device to adhere to specific areas of the body, achieving a cupping effect. However, since the negative pressure is created by controlling a solenoid valve, the most direct way to release pressure is to remove the device from the skin, allowing the air inside the negative pressure chamber to come into contact with the outside air, thus releasing the pressure. This method is cumbersome and can cause pain to the skin. While some technologies use pressure relief valves to control pressure release, this method is simple, but if the valve is damaged, it will not achieve the desired effect and is more expensive. Therefore, the traditional method of removing the device from the skin remains the only viable option for pressure release. Utility Model Content

[0003] The purpose of this invention is to provide a gua sha device that, through a pressure relief structure, can always conveniently and controllably release pressure. The pressure relief operation is simple and convenient, and will not cause pain to the skin during pressure relief, thus effectively reducing costs.

The push rod 5 and the scraping head 2 are connected... A pressure relief spring 8 is provided between the pressure relief springs, and a pressure relief button 9 is provided at the outer end of the pressure relief push plate 4. When pressure relief is required, press the pressure relief button 9 to push the pressure relief push plate 4 and the push rod 5, so that the pressure relief head 6 is separated from the pressure relief hole 7 for pressure relief. This allows for convenient and controllable pressure relief at all times. The pressure relief operation is simple and convenient, and it will not cause pain to the skin during pressure relief, which can effectively reduce costs. After pressure relief, after releasing the pressure relief button 9, the pressure relief spring 8 will connect the pressure relief head 6 to the pressure relief hole 7, and the sealing ring 10 will seal it. In this way, negative pressure can be generated by the cooperation of the negative pressure air pump and the negative pressure air nozzle 3 for cupping.

[0016] In this embodiment, the device includes an upper shell and a base 20. The upper end of the base 20 is provided with a sliding groove 11. The pressure relief push plate 4 is disposed in the sliding groove 11. One end of the push rod 5 is connected to one end of the sliding groove 11. The other end of the base 20 corresponding to the sliding groove 11 is provided with a pressing hole to facilitate the setting of the pressure relief button 9. A sealing sleeve is provided between the pressing hole and the pressure relief button 9. The negative pressure nozzle 3 is disposed in the middle of the base 20. The pressure relief push plate 4 is fixedly slidable in the sliding groove 11 to facilitate the accurate separation or connection of the pressure relief head 6 and the pressure relief hole 7.

[0017] In this embodiment, a connecting plate 12 is provided between the upper shell and the base 20. A vibration motor 13 and a solenoid valve 14 are mounted on the connecting plate 12.

The inner end of the pressure relief pull plate 17 is provided with a pull rod 18 connected to one end of the slide groove 11. The inner side of the pull rod 18 is provided with a pressure relief head 6. The negative pressure nozzle 3 has a pressure relief hole 7 that cooperates with and connects to the pressure relief head 6. A pressure relief spring 8 is provided between the push rod 5 and the slide groove 11. The outer end of the pressure relief pull plate 17 is provided with a pressure relief handle 19. In this embodiment, by pulling the pressure relief handle 19, the pressure relief pull plate 17 and the pull rod 18 are moved, thereby separating the pressure relief head 6 from the pressure relief hole 7 for pressure relief. After pressure relief, after releasing the pressure relief handle 19, the pressure relief head 6 is connected to the pressure relief hole 7 under the action of the pressure relief spring 8, and is sealed under the action of the sealing ring 10, which facilitates the next negative pressure cupping.

[0019] In addition to pressing and pulling to relieve pressure, the inner end of the pressure relief push plate 4 or pressure relief pull plate 17 can be connected to the arc-shaped push rod 5 or pull rod 18. The pressure relief push plate 4 or pressure relief pull plate 17 is axially connected to the upper end of the base 20.
