For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] Reference Figures 1 to 5 An embodiment of the present invention provides a cupping device, including a cupping body 100, a vacuum assembly 200, an electrically controlled pressure protection assembly 300, and a mechanical pressure protection assembly 400.

[0031] A cavity 110 is provided inside the tank body 100 , and one end of the cavity 110 is open.

[0032] The suction component 200 is used to suck the air in the cavity 110 to form a negative pressure in the cavity 110, so that the open end of the can body 100 is adsorbed on the treatment site. Specifically, the suction component 200 can be a suction pump.

[0033] The electrically controlled pressure protection assembly 300 includes a detector 310, a control module 320 and an execution module 330. The detector 310 and the execution module 330 are both electrically connected to the control module 320. The detector 310 is used to detect the air pressure in the cavity 110 and feed it back to the control module 320. When the air pressure detected by the detector 310 is less than a first predetermined value, the control module 320 controls the execution module 330 to operate, so that the execution module 330 increases the air pressure in the cavity 110.

[0034] Specifically, the detector 310 may adopt an air pressure sensor, and the control module 320 may adopt a control chip such as a microcomputer or a PLC.

[0035] The mechanical pressure protection assembly 400 includes a housing 410 and a sealing mechanism. A sealing cavity 411 communicating with the cavity 110 is provided in the housing 410. A through hole 412 for communicating with the outside is provided at one end of the sealing cavity 411. The sealing mechanism can be movably arranged and formed into a first position state and a second position state. In the first position state, the sealing mechanism blocks the through hole 412. When the air pressure in the cavity 110 is less than the second predetermined value, the air pressure difference between the outside and the sealing cavity 411 drives the sealing mechanism to move to the second position state, so that the through hole 412 is conductive.

[0036] The cupping device of this embodiment adopts double negative pressure protection, wherein the detector 310 of the electrically controlled pressure protection assembly 300 can detect the air pressure in the cavity 110 in the cup body 100 and feed back to the control module 320. When the air pressure is less than a first predetermined value, the control module 320 controls the execution module 330 to increase the air pressure in the cavity 110, thereby preventing tissue damage at the treatment site caused by excessively low air pressure. The sealed cavity 411 in the shell 410 of the mechanical pressure protection component 400 is connected to the cavity 110 of the tank body 100, and the air pressure of the two is the same. The sealing mechanism can be movably arranged and formed into a first position state and a second position state. In the first position state, the tank body 100 works normally, and the sealing mechanism blocks the through hole 412. When the air pressure of the cavity 110 in the tank body 100 is less than the second predetermined value, the air pressure difference between the outside and the sealed cavity 411 drives the sealing mechanism to move to the second position state, so that the through hole 412 is connected, and the pressure is released. The outside gas enters the sealed cavity 411 and the cavity 110, and the air pressure in the sealed cavity 411 and the cavity 110 is increased, thereby preventing the damage of the tissue at the treatment site caused by too low air pressure. With double negative pressure protection, when one of the protection components is abnormal, the other can also perform air pressure protection, which can effectively prevent the damage of the tissue at the treatment site caused by too low air pressure, and improve the reliability and safety of work.

[0037] The second predetermined value is the same as or different from the first predetermined value.

[0038] Specifically, if the second predetermined value is set to be the same as the first predetermined value, when the air pressure in the cavity 110 drops below the first predetermined value (or the second predetermined value), the execution module 330 of the electrically controlled pressure protection component 300 and the sealing mechanism of the mechanical pressure protection component 400 operate simultaneously to jointly increase the air pressure in the cavity 110. If one of them fails, the other operates alone.

[0039] If the second predetermined value is set to be smaller than the first predetermined value, when the air pressure in the cavity 110 drops below the first predetermined value, the execution module 330 of the electrically-controlled pressure protection component 300 will act first, and the mechanical pressure protection component 400 will not act; if the electrically-controlled pressure protection component 300 fails and the air pressure in the cavity 110 continues to drop to less than the second predetermined value, the sealing mechanism of the mechanical pressure protection component 400 will then act.

[0040] If the first predetermined value is set to be greater than the second predetermined value, when the air pressure in the cavity 110 drops below the second predetermined value, the sealing mechanism of the mechanical pressure protection component 400 executes an action, and the execution module 330 of the electrically-controlled pressure protection component 300 does not execute an action; if the mechanical pressure protection component 400 fails and the air pressure in the cavity 110 continues to drop to less than the first predetermined value, the execution module 330 of the electrically-controlled pressure protection component 300 executes an action.

[0041] In some embodiments of the present invention, the execution module 330 includes a solenoid valve, which is provided with a valve port, and the valve port selectively connects (conducts or cuts off) the outside world and the cavity 110. When the tank body 100 is in normal working state, the valve port is normally closed, disconnecting the connection between the outside world and the cavity 110; when the air pressure in the tank body 100 drops to less than the first predetermined value, the control module 320 controls the solenoid valve to open, so that the outside world and the cavity 110 are connected, the outside air enters the cavity 110, and the air pressure in the cavity 110 increases; until the air pressure in the cavity 110 detected by the detector 310 is greater than the first predetermined value, the control module 320 controls the solenoid valve to close.

[0042] Of course, it is understandable that the execution module 330 of the electronically controlled pressure protection assembly 300 may adopt different structures as long as it can increase the air pressure in the cavity 110 . For example, the execution module 330 may also adopt an air pump to pump gas into the cavity 110 .

[0043] In some embodiments, the cavity 110 includes a first half 111 and a second half 112, and an air hole 113 is provided between the first half 111 and the second half 112, and the first half 111 and the second half 112 are connected through the air hole 113, and the opening is arranged at one end of the first half 111, and the detector 310 is arranged in the first half 111, and the air extraction component 200, the control module 320 and the execution module 330 are arranged in the second half 112, and the first half 111 and the air extraction component 200 are connected to the electromagnetic valve by a pipeline. The first half 111 is the part that contacts the treatment part of the human body, and the second half 112 is the part where the main electrical components are installed. The two are separated and connected through the air hole 113 to realize air pressure control, which is conducive to the maintenance and modularization of the device.

[0044] A battery 120 is also provided in the second half 112, and an interactive interface 130 is provided on the top of the shell of the second half 112. The interactive interface 130 can be a touch screen or set buttons to control the operation of the tank body 100, such as controlling the vacuum assembly 200 to draw air to form negative pressure.

[0045] In some embodiments of the present invention, the sealing mechanism includes a pressing member 420 and a sealing member 430. The via hole 412 passes through one end of the housing 410 and the sealing member 430. The sealing member 430 is annular. The pressing member 420 is movably arranged. In the first position state, the pressing member 420 and the sealing member 430 are in close contact to block the via hole 412. In the second position state, the pressing member 420 is separated from the sealing member 430 to make the via hole 412 conductive. The via hole 412 is conductive or blocked by the cooperation between the pressing member 420 and the sealing member 430.

[0046] In a further embodiment, the mechanical pressure protection assembly 400 further includes an elastic member 440, which is used to provide a force for the pressing member 420 to block the through hole 412, that is, to maintain the sealing mechanism in the first position state, and the tank body 100 works normally at this time. When the air pressure in the cavity 110 is less than the second predetermined value, the pressure of the air pressure difference between the outside and the sealed cavity 411 on the pressing member 420 is greater than the elastic force of the elastic member 440, thereby driving the pressing member 420 to move to the second position state, so that the through hole 412 is conductive. Specifically, the elastic member 440 can be a spring installed in the sealed cavity 411.

[0047] In some embodiments, one end of the pressing member 420 extends into the sealing cavity 411 and forms a working end 421. Specifically, the working end 421 is in a flat circular shape. In the first position state, one end surface of the working end 421 abuts against the sealing member 430 and the other end surface abuts against the elastic member 440. The elastic member 440 abuts against one side of the working end 421, so that the other side of the working end 421 is closely attached to the sealing member 430, thereby blocking the via 412.

[0048] In a further embodiment, the pressing member 420 further includes a pressing cap 422 located outside the sealed cavity 411 and a connecting portion 423 connecting the pressing cap 422 and the working end 421, the connecting portion 423 is columnar and passes through the through hole 412, and the diameter of the connecting portion 423 is smaller than the diameter of the through hole 412. The pressing cap 422 is used for the operator to press to drive the pressing member 420 to move to the second position state, so that the sealed cavity 411 is depressurized. Manual depressurization can be achieved through the pressing cap 422, that is, even if the air pressure in the cavity 110 and the sealed cavity 411 is not less than the second predetermined value, the pressing cap 422 can be pressed to overcome the elastic force, so that the working end 421 of the pressing member 420 is separated from the sealing member 430, the through hole 412 is connected, and the outside air enters the sealed cavity 411 and the cavity 110. When the cupping work is completed by the cupping body 100, the pressure can be actively released through the pressing cap 422.

[0049] In some embodiments, a slide groove 413 is provided on the housing 410, and the pressing cap 422 is slidably connected to the slide groove 413. A limiting protrusion 414 is provided on the inner wall of the slide groove 413. In the first position state, the pressing cap 422 abuts against the limiting protrusion 414, thereby limiting the pressing cap 422. The movement of the pressing cap 422 is guided by the slide groove 413.

[0050] In some embodiments of the present invention, the mechanical pressure protection assembly 400 also includes a connector 450, which seals one end of the shell 410 away from the through hole 412. The connector 450 is threadedly connected to the shell 410 for adjusting the compression amount of the elastic member 440 by screwing, that is, adjusting the elastic force of the elastic member 440, thereby adjusting the size of the second predetermined value.

[0051] In a further embodiment, one end of the elastic member 440 is in contact with the joint 450, and the joint 450 is provided with a guide post 451, and the elastic member 440 is passed through the guide post 451. The guide post 451 guides the movement of the elastic member 440 to prevent the position of the elastic member 440 in the sealing cavity 411 from shifting, causing the elastic force to change, thereby affecting the stability of the second predetermined value.
