Referring to fig. 6, in this embodiment, a reinforcing pipe is disposed on a door body, and a vent hole communicating with the reinforcing pipe is disposed on one side of the door body, and air interaction with the outside can be achieved through the vent hole and the reinforcing pipe, so as to achieve the purpose of ventilation.
Referring to fig. 5 and 7-8, in this embodiment, in order to achieve the purpose of ventilation, a micro pump is disposed on a door frame, a gas source for gas flow is implemented by the micro pump, when ventilation is implemented, an electromagnet is energized and attracts a folding movable shaft to be unfolded, and a notch on a second movable tube is dislocated from the second air tap and seals the second air tap, while a first movable tube opens the first air tap, and simultaneously seals one end of the first movable tube by using a sealing body at one end of an inner core, when the micro pump is started, gas in the first movable cavity is pumped out through the first air tap, so as to form a negative pressure, therefore, a sealing plug moves towards a direction close to the first movable tube and opens the first movable cavity, and in the same way, when gas in the second cavity is pumped out, the second cavity forms a negative pressure, so that the sealing body opens one side of the penetrating cavity close to the reinforcing tube (at the moment, the sealing plate is also one side of opening the penetrating cavity and the second cavity), and the indoor gas flow can enter the reinforcing tube from the vent hole on the door body, and is discharged from the first movable cavity through the first air tap, so as to complete ventilation;
in the above process, when the sealing plug in the first movable cavity is opened, the end, connected with the extension rod, of the hinge rod is close to the direction of the first movable cavity, so that the hinge rod and the end of the second movable tube move to the side close to the penetrating cavity, and the limiting body is enabled to enter the limiting groove of the door body, therefore, the matching effect of the limiting body and the limiting groove can be ensured when ventilation is carried out, and the air flow interaction effect (ventilation effect) is more stable.
In addition, in order to further improve the matching effect of the door body and the door frame and improve the anti-theft effect, the micro pump can be started when the electromagnet is powered off, and more details are that:
when the electromagnet is powered off, the folding movable shaft is controlled to be folded by the limiting spring, so that a notch on the second movable pipe is communicated with the second air tap, the limiting body is led to enter a limiting groove of the door body, meanwhile, the first movable pipe moves in the first movable cavity, so that a sealing body on the inner core opens the end part of the first movable pipe, the first movable pipe is sealed by the first movable pipe, when the second movable pipe moves, the first movable cavity can be opened by the hinge rod, in this state, a sealing plate in the penetrating cavity seals the communicating part of the penetrating cavity and the second cavity (when the limiting body moves, the sealing plate is contacted with the cavity wall of the penetrating cavity, so that one side of the penetrating cavity is sealed, and when the limiting body moves continuously to the side close to the reinforcing pipe, the sealing plate can be contacted with the inner wall of the penetrating cavity more tightly by the telescopic spring in the telescopic cavity, at the same time, the sealing body is partially exposed from the other side of the penetrating cavity, and when the limiting body enters the limiting groove, one end of the sealing body is also clamped into the reinforcing pipe to form a limiting and limiting block of the movable region of the sealing body;
after the limiting body enters the limiting groove, the limiting body is in contact with the groove wall of the limiting groove, the plugging body is matched with the pipe orifice of the reinforcing pipe, at the moment, the micro pump is started, air in the folding movable shaft (through the strip-shaped opening on the first movable pipe) and air in the second cavity can be pumped away, when the folding movable shaft and the air in the second cavity are pumped away, negative pressure is formed in the folding movable shaft, so that the standard air pressure existing in the first cavity can press the folding movable shaft to the separating body, and the second movable pipe presses the limiting body into the limiting groove, so that the matching effect of the door body and the door frame is improved;
it is worth mentioning that, because the sealing body seals the reinforcement pipe (so to speak, the one end of the reinforcement pipe limits the movement of the sealing body), and the penetrating cavity is consistent with the external air pressure, the sealing body cannot be pushed open, so that the negative pressure is formed in the second cavity in time, and the limiting body is also stable in the limiting groove.
