4. A vacuum drainage non-electromechanical micro-pressure opening structure as claimed in claim 1, wherein: the cross-sectional area of the taper pipe (105) is small at the top and big at the bottom, and the lower part of the taper pipe (105) is provided with a through hole.
5. The method of using a vacuum drainage non-electromechanical micro-pressure opening structure as claimed in claim 1, comprising the steps of:
1) a top cover (6) is arranged on the lower side of the main shell (1), a connecting air hole (601) in the top cover (6) is ensured to be communicated with the taper pipe (105), a Z-shaped warping plate (3) is sleeved on the middle support column (103) through a waist-shaped hole (303), a long tongue plate (302) is ensured to be positioned in the U-shaped baffle (102), and a rubber block (4) arranged in a rubber mounting hole (306) is pressed at the upper end of the taper pipe (105); the connecting air hole (601) is connected with the vacuum valve;
2) placing a supporting column (203) at the lower end of the U-shaped pressing plate (2) in a circular groove (101), pressing a poke rod (202) on a warped rod (304), arranging a reset push rod (5) in a small circular hole (104) of the main shell (1), and positioning one end of the reset push rod (5) in a groove (204) of the U-shaped pressing plate (2);
3) the upper side of the main shell body (1) is sequentially provided with a supporting plate (7), a rubber film (8) and a fixing cover (9), a fixing ring block (801) of the rubber film (8) is tightly pressed in a fixing ring groove (107) through the fixing cover (9), a working column (11) is arranged on the lower side of a middle convex block (804), a rubber plugging plate (10) is covered in a concave groove (901), and a micro-pressure hole (903) is connected with a device for generating micro-pressure;
4) when micro-air pressure is generated by the micro-air pressure device, air flow directly enters a gap between the upper side of the planar membrane (802) and the lower side of the concave groove (901), the micro-air pressure starts to generate pressure on the centering bump (804) to enable the inclined membrane (803) to start stretching, the centering bump (804) starts to enter the central through hole (701), and the lower end of the working column (11) is in contact with the long tongue plate (302) and pushes the long tongue plate (302) to move towards the top cover (6);
5) the bottom surface of the rubber block (4) is separated from the upper end of the taper pipe (105) by the Z-shaped wane (3) under the action of the fulcrum of the middle support (103), so that external air flow enters the taper pipe (105) through the air inlet hole (106) and then enters the connecting air hole (601) to control the action of a vacuum valve, and the required function is realized;
6) when the vacuum valve is required to be closed, the reset push rod (5) can be used for sliding towards the inner part of the main shell (1) to force the poke rod (202) of the U-shaped pressing plate (2) to downwards press the warping rod (304), so that the rubber block (4) is ensured to cover the taper pipe (105), the good vacuum effect of the vacuum valve is ensured, and the vacuum valve stops working.
