When the cover 100 is covered on the opening 11 of the pot body 10, the flange 150 stops at the top of the opening of the opening 11 to thereby support and fix the cover 100 to the opening 11, and the sealing ring 140 abuts against the pot body 10. The inner wall surface seals the opening 11.

The handle 200 is disposed on the outer side 120 of the cover 100. In the present embodiment, the handle 200 is preferably a cylinder that is erected on the outer side 120 of the cover 100, but the present invention is not limited thereto. Specifically, the handle 200 is coupled to the cover 100 by a fixing member 210. In the present embodiment, the fixing member 210 is preferably a screw, but the present invention is not limited thereto, and the fixing member 210 is inserted into the center of the handle 200 from the center of the inner side 110 of the cover 100 through the cover 100. The cover body 100 and the handle 200 are respectively provided with a pair of positioning structures 130/230 correspondingly fastened. In the present embodiment, the positioning structure 130 on the cover 100 is a recess, and the positioning structure 230 on the handle 200 is a corresponding block of the engaging recess, but the present invention is not limited thereto. A lifting pipe 201 is disposed in the handle 200. One end of the moving pipe 201 is connected to the through hole 101 of the cover body 100, and the handle 200 is provided with a pressure releasing hole 202 on the side of the moving pipe 201. In the present embodiment, the moving pipe 201 extends up and down parallel to the central axis of the handle 200 to penetrate the handle 200, and the lower end of the moving pipe 201 is aligned to connect the through hole 101 in the cover 100, and the pressure relief hole 202 is opened. On the side of the handlebar 200.

Referring to FIGS. 1 through 5, the valve assembly 300 includes a piston 310. In the present embodiment, the piston 310 preferably has a cylindrical shape that cooperates with the moving pipe 201. The piston 310 is bored in the moving pipe 201 and can move along The pipe 201 moves. In the present embodiment, the tip end of the piston 310 is exposed or protruded from the top end of the moving pipe 201 to be pressed by the user to move the piston 310 toward the inner side 110 of the cover 100. The lower end of the piston 310 penetrates through the through hole 101 into the inner side 110 of the cover 100 and the lower end of the piston 310 is provided with an end plug 320. The end plug 320 is located at the inner side 110 of the cover 100 and the outer diameter of the end plug 320 is larger than the aperture of the through hole 101. . Thereby, the piston 310 can move along the moving duct 201 toward the outer side 120 of the opposite body to cause the end plug 320 to close the through hole 101. A pressure relief passage 311 is disposed in the piston 310, and the pressure relief passage 311 is open at both ends. In the embodiment, the pressure relief passage 311 extends in the longitudinal direction of the piston 310, and the two ends of the pressure relief passage 311 are respectively connected to the piston 310. The side. When the end plug 320 closes the through hole 101, the upper end of the pressure relief passage 311 is offset from the pressure relief hole 202 and is closed by the inner wall of the moving pipe 201. The movement of the piston 310 along the moving pipe 201 toward the inner side 110 of the cover 100 enables the end plug 320 to leave the through hole 101. When the end plug 320 leaves the through hole 101, the lower end of the pressure relief passage 311, that is, the end communicates with the inner side 110 of the cover 100. After the upper end of the pressure relief passage 311 is moved to the connection pressure relief hole 202, the inner side 110 of the cover body 100 communicates with the outer side 120 of the cover body 100 through the pressure relief passage 311, so that the pressure inside and outside the pressure relief pot can pass through the pressure relief passage. 311 balance.

An elastic member 330 is disposed between the piston 310 and the cover 100. The elastic member 330 is used to push the piston 310 to move to the outer side 120 of the cover 100, thereby moving the end plug 320 toward the through hole 101. In the present embodiment, the elastic member 330 is preferably a rubber telescopic sleeve, but the present invention is not limited thereto. For example, the elastic member 330 may also be a spring. Specifically, the outer diameter of the top end of the piston 310 cooperates with the inner diameter of the moving pipe 201 to close the moving pipe 201. The outer diameter of the middle portion of the piston 310 is smaller than the outer diameter of the top end of the piston 310, and the diameter of the through hole 101 on the cover 100 is smaller than The inner diameter of the pipe 201 is moved. The elastic member 330 is sleeved on the middle portion of the piston 310. The two ends of the elastic member 330 respectively abut the periphery of the through hole 101 on the cover 100 and the top end of the piston 310. Thereby, the elastic member 330 can move the piston 310 toward the outer side 120 of the cover 100 along the moving duct 201 to close the opening of the end plug 320.

The pressure relief pot and the pressure relief pot cover thereof have a movable piston 310. The piston 310 is provided with a pressure relief passage 311 and the pressure relief passage 311 can be selectively closed or the pressure relief passage can be closed by moving the piston 310. 311 connects the inner side 110 and the outer side 120 of the pressure relief pot cover. When the air pressure in the pressure relief pot is lower than the atmospheric pressure outside the pressure relief pot, the pressure inside and outside of the pressure relief pot can be balanced by the pressure relief passage 311 to facilitate opening. Cover 100.
