Referring to fig. 1, 8 to 11, the operation of the intake valve in the present embodiment will be briefly described with reference to the drawings.

As shown in fig. 1, the intake valve is in an initial state.

Specifically, at this time, the screw cap body 1 is in a separable state, the rotary cap body 1 does not cover the exhaust hole 43, the exhaust hole 43 can communicate with the outside, but at this time, the side of the air intake valve body 4 contacts with the second seal ring 5 on the seal piston body 6, and the hole on the air intake valve housing 7 is blocked, so that the air communication cannot be performed.

At this time, the rotation base 133 is located at the bottom space 613, the rotation slope 132 contacts the piston slope 612, and the rotation stopper 134 contacts the convex top 611.

As shown in fig. 8 to 9, the intake valves are in a sealed state.

Specifically, when it is necessary to seal the intake valve from gas communication, the user rotates the rotary cover 1 by hand, and rotates the rotary cover 1 clockwise, so that the rotary cover 1 seals the exhaust hole 43.

Specifically, when the rotary cap 1 is rotated, the rotary ramp 132 contacts the piston ramp 612 under the action of the external force, and the rotary ramp 132 slides on the piston ramp 612 under the guiding action of the piston ramp 612 and the rotary ramp 132. Until the rotation of the cap body 1 completely seals the exhaust hole 43.

As shown in fig. 10-11, the intake valve is in a deflated state.

Specifically, when the air in the intake valve needs to be exchanged, the user rotates the rotary cover 1 by hand, and rotates the rotary cover 1 clockwise, so that the exhaust hole 43 is exposed by the rotary cover 1.

Specifically, when the rotary cap 1 is rotated, the rotary ramp 132 contacts the piston ramp 612 under the action of the external force, and the rotary ramp 132 slides on the piston ramp 612 under the guiding action of the piston ramp 612 and the rotary ramp 132. Until the rotary bottom 133 is located at the convex top 611, the whole position of the rotary cover 1 is too high, and the rotary cover 1 does not cover the exhaust hole 43, and the exhaust hole 43 is exposed.

At this time, since the sealing piston body 6 is fixedly connected to the intake valve housing 1 and cannot move, when the rotary cover body 1 rotates, the intake valve body 4 is also moved upward by the rotary cover body 1, the side of the intake valve body 4 is separated from the second seal ring 5 on the sealing piston body 6, and gas can be exchanged between the exhaust hole 43 and the intake valve housing 7.

Since the rotary cover 1 drives the air intake valve body 4 to move upward, the elastic body 3 is compressed, and therefore the elastic body 3 always has an acting force for pressing the air intake valve body 4 downward.

After the air leakage is completed, the cover body 1 does not need to be rotated, the air inlet valve main body 4 is pressed downwards under the tension action of the elastic body 3, so that the side edge of the air inlet valve main body 4 is contacted with the second sealing ring 5, and the sealing effect is realized again.

The detailed description of the embodiments of the present invention has been presented, and it will be apparent to those skilled in the art that the present invention can be modified and modified without departing from the principles of the present invention, and the modifications and modifications also belong to the protection scope of the claims of the present invention.
