[0002] Cupping, as a traditional Chinese medicine therapy, has a long history of application. It primarily works by creating negative pressure on the skin to promote blood circulation, relieve pain, and treat diseases. However, existing cupping devices generally suffer from insufficient sealing, inconvenient operation, and unstable effects, necessitating an improved cupping device to address these shortcomings.

[0003] The working principle of cupping devices is generally based on negative pressure, creating a pressure difference between the inside and outside of the cup by heating the cup at high temperature or by using a mechanical pump to draw in air. Some existing cupping devices use mechanical structures or hot air to generate negative pressure, but these devices have certain problems in terms of sealing and operational flexibility. Currently available cupping devices generally require the user to apply considerable force during removal, making operation inconvenient and affecting their efficiency and comfort.

[0022] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0023] refer to Figures 1-3As shown, a cupping device for traditional Chinese medicine includes a cupping body 1. The cupping body 1 is hollow with an open bottom. A lip 11 is provided on the outer side of the open bottom of the cupping body 1. The lip 11 is made of high-strength silicone rubber, possessing good elasticity and wear resistance. The design of the lip 11 aims to increase the contact area between the cupping body 1 and the skin, thereby improving the sealing effect and preventing gas leakage during use. A boss 12 is provided at the center of the top of the cupping body 1. The surface of the boss 12 is made of high-temperature and corrosion-resistant ABS engineering plastic, possessing good high-temperature resistance and capable of withstanding the heat generated during cupping. A first air inlet 13 with a diameter of 4mm is provided on one side of the surface of the boss 12. An installation cylinder 14 is provided on the other side of the surface of the boss 12. The installation cylinder 14 is made of stainless steel, possessing excellent corrosion resistance and high strength. Inside the installation cylinder 14, a shaft core 2 is rotatably mounted. The shaft core 2 is made of hard aluminum alloy, possessing high strength and wear resistance, ensuring the long-term stability of the shaft core 2. A vent hole 21 with a diameter of 2mm is provided at the bottom of the shaft core 2. A second air inlet hole 25 is provided on the side surface of the shaft core 2, which communicates with the vent hole 21. The second air inlet hole 25 corresponds to the first air inlet hole 13 to ensure smooth gas flow and avoid uneven negative pressure. A limiting platform 22 is provided at the top of the shaft core 2. The cross-sectional area of ​​the limiting platform 22 is larger than that of the shaft core 2. The limiting platform 22 is located on the top of the boss 12. A knob 23 is provided at the end of the limiting platform 22 away from the shaft core 2. The knob 23 is made of plastic for easy operation and can flexibly adjust the position of the shaft core 2 when rotated.

[0024] refer to Figure 3 As shown, two sealing rings 3 are fitted onto the surface of the shaft core 2. The sealing rings 3 are made of fluororubber, possessing excellent high-temperature resistance and chemical corrosion resistance, effectively preventing air leakage during cupping and ensuring stable negative pressure inside the cupping jar 1. The two sealing rings 3 are positioned on the upper and lower sides of the second air inlet 25 respectively, ensuring optimal sealing. A retaining ring 4 made of stainless steel is installed below the surface of the shaft core 2. Positioned inside the upper part of the cupping jar 1, the retaining ring 4, together with the large-section limiting platform 22 at the other end, serves to fix the shaft core 2, preventing axial displacement during use.

[0025] refer to Figure 2 and Figure 3 As shown, the surface of the limiting platform 22 is equipped with an indicator needle 24, which is made of high-temperature resistant plastic. The indicator needle 24 corresponds to the second air inlet 25, and the two are at the same angle, making it easy for the user to know the position of the second air inlet 25 based on the indication of the indicator needle 24. The surface of the shaft core 2 also has a positioning hole 26, which is distributed at a 90-degree angle to the second air inlet 25. The positioning hole 26 is a blind hole structure, which can accurately lock the position of the shaft core 2 and prevent leakage caused by excessive rotation of the shaft core 2.

[0026] refer to Figures 2-4 As shown, a horizontal mounting hole 15 is provided inside the mounting cylinder 14. A positioning bolt 5 is slidably installed inside the mounting hole 15. The positioning bolt 5 is made of wear-resistant stainless steel to ensure stability and high strength after long-term use. The end of the positioning bolt 5 is matched with the internal dimensions of the positioning hole 26 to ensure precise fit. A connecting rod 51 is provided on the outer end of the positioning bolt 5, and the connecting rod 51 penetrates the end surface of the mounting cylinder 14. The connecting rod 51 is made of high-strength alloy steel, which has strong tensile strength and wear resistance, and can withstand the force that may be applied during the use of the cupping device.

[0027] refer to Figure 4 and Figure 5 As shown, a concave ring 52 is provided at the end of the connecting rod 51. The concave ring 52 is located outside the mounting cylinder 14. The design of the concave ring 52 can better cooperate with other components and improve the stability of the structure. A spring 6 is sleeved on the surface of the connecting rod 51. The spring 6 is made of stainless steel and has good elasticity and fatigue resistance. The spring 6 is placed inside the mounting hole 15, with one end in contact with the end surface of the positioning bolt 5 and the other end in contact with the inside of the mounting cylinder 14. This ensures that the positioning bolt 5 can maintain a certain inward force under the action of the spring, thereby ensuring that the positioning bolt 5 remains in contact with the positioning hole 26 to ensure fixation during non-venting processes of the cupping device, preventing air leakage due to misoperation.

[0028] refer to Figure 4 and Figure 5 As shown, a mounting base 141 is provided above the end of the mounting cylinder 14. A swing rod 7 is hinged to the surface of the mounting base 141. The swing rod 7 is made of aluminum alloy, which is lightweight and sturdy. A U-shaped fork rod 71 is provided at the bottom of the swing rod 7. The U-shaped fork rod 71 is open downwards and is engaged inside the concave ring 52. The design of the U-shaped fork rod 71 ensures a precise fit between the connecting rod 51 and the swing rod 7, avoiding unstable operation. This design plays an important adjustment role in the operation of the cupping device, allowing users to more easily and accurately adjust the working state of the cupping device.

[0029] The working principle of this utility model is as follows: During use, the shaft core 2 rotates inside the boss 12, and both ends are limited by the limiting platform 22 and the retaining ring 4 respectively, so as to ensure that the shaft core 2 can only rotate and cannot move axially. At the same time, the sealing rings 3 placed on both sides of the second air inlet 25 can improve the sealing performance of the shaft core 2 and the tank body 1 and prevent air leakage. Due to the presence of the spring 6, the positioning bolt 5 has an inward force, which in turn pulls the connecting rod 51 closer to the axis position of the tank body 1. Through the cooperation of the concave ring 52 and the U-shaped shift fork rod 71, the end of the swing rod 7 is driven to tilt outward. Through the positioning bolt 5 and the positioning hole 26 The two parts work together to ensure the stability of the angle of the shaft core 2. Since the positioning hole 26 and the second air inlet 25 are at 90 degrees respectively, and the boss 12 and the mounting cylinder 14 are symmetrically arranged, when the positioning bolt 5 is engaged with the positioning hole 26, the second air inlet 25 and the first air inlet 13 are completely misaligned, so that the inside of the canister 1 remains sealed and the sealing is guaranteed when cupping is performed. The canister 1 is heated by igniting the alcohol sponge, and then the port of the canister 1 is quickly covered on the skin. After the inside cools down, a negative pressure is formed to realize cupping. The lip 11 can increase the contact area between the canister 1 and the skin and improve the sealing effect.

[0030] When it is necessary to remove it, hold the knob 23 and press the end of the swing rod 7 inward. At this time, the connecting rod 51 can be pulled outward by the cooperation of the U-shaped fork rod 71 and the concave ring 52, so that the positioning bolt 5 is disengaged from the positioning hole 26. Then, turning the knob 23 can drive the shaft core 2 to rotate as a whole, so that the second air inlet 25 gradually coincides with the first air inlet 13, so that external air can enter the inside of the tank 1, and the internal pressure of the tank 1 is restored. At this time, it can be easily removed. The outer indicator needle 24 is at the same angle as the second air inlet 25 for easy observation.

[0031] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
