Description

Technical Field

[0001] This utility model relates to the field of massage therapy technology, and in particular to a manual pressure relief device for a scraping instrument. 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 manual pressure relief 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 detach the manual pressure relief device from the skin, allowing outside air to enter and release the pressure. This method is cumbersome and can cause pain. While some technologies use pressure relief valves, this is simpler, but if the valve is damaged, it won't release pressure effectively and is more expensive. Therefore, the traditional method of detaching the device from the skin remains the only viable option. Utility Model Content

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0018] Example 1, as Figure 1-3 As shown, a manual pressure relief device for a gua sha instrument includes a handle 1, a negative pressure air pump inside the handle 1, a gua sha head 2 at the lower end of the handle 1, a negative pressure air nozzle 3 inside the gua sha head 2 for use with the negative pressure air pump, a pressure relief assembly inside the handle 1 and the gua sha head 2, the pressure relief assembly including a pressure relief frame 4 located inside the handle 1 and sleeved outside the negative pressure air pump, a pressure relief button 5 at the upper end of the pressure relief frame 4, a pressure relief rod 6 at the lower end of the pressure relief frame 4, a connecting sleeve 7 at the upper part of the gua sha head 2, a rocker arm 8 at the lower end of the pressure relief rod 6 connected to the connecting sleeve 7 via a connecting shaft, a pressure relief plug 9 at the lower part of the other end of the rocker arm 8, and a negative pressure air nozzle... The upper end of the device 3 has a pressure relief hole 10, and a pressure relief spring 11 is provided between the rocker plate 8 and the connecting shaft. When pressure relief is required, press the pressure relief button 5 to drive the pressure relief frame 4 and the pressure relief rod 6 to move down, push the rocker plate 8 to rotate, and pull the pressure relief plug 9 out of the pressure relief hole 10 to release pressure. This allows for convenient and controllable pressure relief at all times. The pressure relief operation is simple and convenient and can effectively reduce costs. After pressure relief, after releasing the pressure relief button 5, the rocker plate 8, under the action of the pressure relief spring 11, causes the pressure relief plug 9 to move down and return to its original position, sealing it with the pressure relief hole 10. The sealing is also achieved by the sealing ring 14 on the outer wall of the pressure relief plug 9. This allows negative pressure to be generated through the cooperation of the negative pressure air pump and the negative pressure air nozzle 3 for cupping.

[0019] Example 2, as Figure 4 As shown, in this embodiment, the pressure relief assembly includes a pressure relief frame 4 disposed inside the handle 1 and sleeved outside the negative pressure air pump. The pressure relief frame 4 has a pressure relief button 12 at its upper end and a pressure relief rod 6 at its lower end. A pressure relief spring 13 is provided between the pressure relief rod 6 and the connecting sleeve 7. A pressure relief plug 9, corresponding to the pressure relief hole 10, is provided at the lower end of the pressure relief rod 6. A sealing ring 14 is provided on the outer wall of the pressure relief plug 9. The scraping head 2 includes an upper shell 15 and a base 16. The connecting sleeve 7 is disposed in the upper part of the upper shell 15. A lower collar 18 is provided inside the connecting sleeve 7. An upper collar 17 is provided on the upper part of the pressure relief rod 6. The pressure relief spring... 13 is located between the upper collar 17 and the lower collar 18. When pressure relief is required, the pressure relief button 12 is pulled up, which moves the pressure relief frame 4, pressure relief rod 6 and pressure relief plug 9 upward, so that the pressure relief plug 9 is separated from the pressure relief hole 10 and pulled out to relieve pressure. This allows for convenient and controllable pressure relief at all times. The pressure relief operation is simple and convenient and can effectively reduce costs. After pressure relief, after releasing the pressure relief button 12, the pressure relief spring 13 causes the pressure relief plug 9 to move down and return to its original position and seal with the pressure relief hole 10. It is also sealed by the sealing ring 14 on the outer wall of the pressure relief plug 9. In this way, negative pressure can also be generated by the cooperation of the negative pressure air pump and the negative pressure air nozzle 3 to perform cupping.

[0020] Example 3, as Figure 5 As shown, in this embodiment, the pressure relief assembly includes a pressure relief cylinder 19 disposed between the upper shell 15 and the base 16 and communicating with one side of the negative pressure nozzle 3. A one-way valve 20 is provided inside the pressure relief cylinder 19. A push rod 21 is provided at one end of the one-way valve 20. A pressure relief spring 13 is provided between the one-way valve 20 and the pressure relief cylinder 19. An openable plug 22 is provided at the outer end of the pressure relief cylinder 19. A sealing ring 14 is embedded in the inner wall of the plug 22. When pressure relief is required, the plug 22 is opened, pushing the push rod 21 and simultaneously moving the one-way valve 20 inward. The pressure relief pump 19 allows external gas to enter the negative pressure nozzle 3 for pressure relief, ensuring convenient and controllable pressure relief. The pressure relief operation is simple and convenient, effectively reducing costs. After pressure relief, the plug 22 blocks the pressure relief pump 19, and the one-way valve 20 returns to its original position under the action of the pressure relief spring 13. This prevents leakage caused by negative pressure generated by the cooperation of the negative pressure pump and the negative pressure nozzle 3. Furthermore, the negative pressure generated by the cooperation of the negative pressure pump and the negative pressure nozzle 3 makes the seal between the one-way valve 20 and the pressure relief pump 19 tighter, thus enabling cupping.

[0021] In this embodiment, at least three fastening frames 23 are evenly distributed at the bottom of the upper shell 15, and at least three fastening teeth 24 are evenly distributed on the inner wall of the upper end of the base 16 to fasten with the fastening frames 23. The fastening teeth 24 and the fastening frames 23 are fastened together to facilitate the mounting and dismounting of the base 16 and the upper shell 15.

[0022] Based on the concept of this utility model, there may be changes in the specific implementation methods and application scope. The content of this specification should not be construed as a limitation of this utility model.
