Description

Technical Field

[0001] The utility model belongs to the technical field of cupping devices, and in particular relates to an electric cupping device. Background Art

[0002] Cupping is a tool made of a cup, which uses heat to expel the air inside to create negative pressure, causing the cup to adhere to the skin and cause congestion. Cupping therapy is also a common treatment method in Mongolian medicine. Traditional cupping involves burning alcohol inside the cup to create negative pressure inside the cup, which in turn causes the cup to adhere to the patient's body surface. However, this method may scald the patient and poses a major safety hazard. In the prior art, manual and electric vacuum cupping devices have also been developed. The manual vacuum method requires the operator to pinch the vacuum component to allow the cup to adhere to the patient's body surface. This process consumes the staff's physical strength, while the electric vacuum method can greatly reduce the operator's physical exertion and improve the efficiency of cupping. For example, the "A portable electric cupping device vacuum machine" disclosed in application number "202123105965.1" It is recorded in the patent document that "it consists of a vacuum machine body and a cupping device, wherein a vacuum pump and a control circuit board are arranged in the vacuum machine body; a power switch and an adjustment knob electrically connected to the control circuit board are arranged on the vacuum machine body; a trachea is arranged on the vacuum pump; one end of the trachea penetrates the vacuum machine body; a connecting female head is arranged at the other end of the trachea; the cupping device comprises a bell jar body, a vacuum joint and a safety exhaust valve arranged on the top of the bell jar body, and a connecting male head arranged on the vacuum joint and matching with the connecting female head". When in use, the above device generates negative pressure by vacuuming air in the cupping device through the vacuum machine, so that it can be firmly adsorbed on the patient's body surface. However, the above device still has certain shortcomings: due to the large size of the vacuum machine, it is not convenient to carry, and thus it is not convenient for patients to carry it outside, resulting in certain limitations when using the above device.

[0022] Specifically, the spring 44 drives the blocking ball 45 to be close to the wedge surface 43, so that the second connecting hole 42 can be blocked, and when negative pressure is generated in the tank body 1, the blocking ball 45 can prevent the negative pressure state in the tank body 1 from being destroyed.

[0023] In this embodiment, the conducting assembly 9 includes a guide rod 91, both ends of which are fixedly connected to connecting rods 92, the connecting rod 92 is fixedly connected to the inner wall of the second connecting tube 8, the diameter of the guide rod 91 is smaller than the diameter of the second connecting hole 42, and the sealing ball 45 is located directly below the second connecting hole 42 and has a diameter larger than the diameter of the second connecting hole 42.

[0024] Specifically, when the second connecting tube 8 is plugged into the first connecting tube 2, the guide rod 91 will be inserted into the sealing tube 41 through the second connecting hole 42 and drive the blocking ball 45 to move downward, thereby making the first connecting tube 2, the second connecting tube 8, the first connecting hole 5 and the second connecting hole 42 conductive. When the negative pressure generator is working, air will be evacuated from the tank body 1 so that the tank body 1 is adsorbed on the patient's body surface. When the second connecting tube 8 is pulled out, the sealing ball 45 will be tightly attached to the wedge surface 43 under the action of the spring 44 to block the second connecting hole 42, thereby preventing the negative pressure environment in the tank body 1 from being destroyed.

[0025] In this embodiment, a third connecting tube 10 is arranged in the second connecting tube 8, a sealing ring 11 is fixedly connected between the third connecting tube 10 and the second connecting tube 8, the inner diameter of the second connecting tube 8 matches the outer diameter of the first connecting tube 2, and the outer diameter of the third connecting tube 10 matches the inner diameter of the first connecting tube 2.

When removing the tank body 1, the user only needs to find an additional insertion rod to squeeze the blocking ball 45 downward through the second connecting hole 42 to release the negative pressure environment in the tank body 1. The cupping device has a simple structure, is easy to operate and easy to carry, and is therefore more suitable for users to carry and use.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model.
