referring to fig. 20 and 21 again, in a first structural form of the pressure relief valve 600, the pressure relief valve 600 includes a pressure relief valve mounting portion 610, a valve wing 620 connected to one end of the pressure relief valve mounting portion 610, and a pressure relief valve fixing portion 630 connected to the other end of the pressure relief valve mounting portion 610, the cup cover 300 further has a mounting hole 104, the mounting hole 104 is close to the pressure relief hole 103, the pressure relief valve mounting portion 610 is slidably disposed through the mounting hole 104, the valve wing 620 is exposed out of the cup cover 300, the air inlet valve slides relative to the mounting hole 104 to open or close the valve wing 620 to the pressure relief hole 103, and when the valve wing 620 is far away from and opens the pressure relief hole 103, the pressure relief valve fixing portion 630 is stopped by the inner wall of the cup cover 300.

This embodiment is under the suction effect of power component 120 that bleeds, and relief valve 600 produces the relative slip through between relief valve installation part 610 and the pressure release hole 103 for valve wing 620 with be close to pressure release hole 103 and then close pressure release hole 103, and when needs carried out the pressure release operation, through pulling relief valve 600, make valve wing 620 keep away from bowl cover 300 and open pressure release hole 103, the first structural style structure of relief valve 600 is simple relatively.

The installation hole 104 is disposed annularly, and the pressure relief hole 103 surrounds the periphery of the installation hole 104. The mounting hole 104 is located in the center of the ring formed by the pressure relief hole 103, so that the pressure relief valve 600 is uniformly stressed when the pressure relief hole 103 slides relative to the mounting hole 104 to open or close the pressure relief hole 103, and the movement is linear movement far away from or close to the cup cover 300, so that the opening and closing operation is convenient, and the sealing performance of the pressure relief valve 600 for closing the pressure relief hole 103 is also high.

In order to further improve the air tightness when the pressure relief valve 600 closes the pressure relief hole 103, the outer wall of the cup cover 300 is further concavely provided with a limiting groove 1111, the pressure relief hole 103 penetrates through the bottom wall of the limiting groove 1111, and when the valve wing 620 is close to and closes the pressure relief hole 103, the valve wing 620 is embedded in the limiting groove 1111.

Referring to fig. 22, in a second structural form of the pressure relief valve 600, the pressure relief valve 600 includes a pressure relief valve mounting portion 610, a pressing portion 640 connected to one end of the pressure relief valve mounting portion 610, and a valve wing 620 connected to the other end of the pressure relief valve mounting portion 610, the pressure relief valve mounting portion 610 is slidably disposed through the pressure relief hole 103, the pressing portion 640 is exposed out of the cup cover 300, and the valve wing 620 is located inside the cup cover 300; the pressure release valve mounting portion 610 is further sleeved with an elastic member 660, one end of the elastic member 660 abuts against the pressing portion 640, the other end of the elastic member 660 abuts against the cup cover 300, the elastic member 660 provides elastic force to drive the valve wing 620 to abut against the inner surface of the cup cover 300 and cover the pressure release hole 103, and under the driving of external force, the valve wing 620 is far away from and opens the pressure release hole 103.

Further, a sealing gasket 650 is further installed on a side of the valve wing 620 facing the cup cover 300 in this embodiment. The sealing pad 650 may be made of a silicone material, and may be integrally formed on the valve wing 620, when the pressure relief valve 600 closes the pressure relief hole 103, the sealing pad 650 seals the pressure relief hole 103, and the tightness during the sealing process may be further improved by the arrangement of the sealing pad 650.

Furthermore, in this embodiment, a limiting cylinder 1113 is further protruded from an outer surface of the cap 300, and the limiting cylinder 1113 surrounds the periphery of the valve wing 620. The smooth process of pressing the pressure release valve 600 can be improved through the arrangement of the limiting cylinder 1113.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
