Correspondingly, a hole for the insertion rod 433 to pass through should be opened at the center of the sealing gasket 410.

In a further technical scheme, a screw hole is formed in the inserting rod 433, and the inserting rod 433 is locked on the inner cover 210 through a screw.

In a further technical solution, the cup body 100 includes: the cup comprises a bottom cover 110, an inner cup 120 and a shell 130, wherein the shell 130 is arranged on the bottom cover 110, the inner cup 120 is arranged in the shell 130, and the cup cover 200 is in threaded connection with the cup body 100.

The heating assembly 300 includes: a support 310, a heating element 320 mounted on the support 310, a power strip 330, a control board 340, and a power socket 350.

The control panel 340 is provided with control keys and an indicator light, the control keys are exposed on the bottom cover 110, and the indicator light can be exposed on the bottom cover 110 or can radiate light outwards through a transparent window arranged on the bottom cover 110. In summary, the light of the indicator light can be observed by the user.

The bracket 310 is installed in the bottom cover 110, the power board 330 is installed at the bottom of the bracket 310, the bracket 310 is provided with the heat insulation ring 311, and the heating element 320 is installed on the bracket 310.

The power socket 350 is used for connecting an external power line, so that water in the inner cup 120 is heated by the heating member 320 after being powered on,

the inner lid 210 is fixed on the upper lid 220, the sealing gasket 410 is sealed with the air release hole 212 of the inner lid 210 in a non-heating state, and when the pressure in the cup body 100 exceeds the rated pressure of the spring 420, the valve body sealing gasket 410 is opened, and the steam is automatically discharged from the air release hole 212 of the inner lid 210.

When the utility model is used, the cover can be opened to boil water or not, and when the water temperature is not 95-100 ℃, the valve is in a normally closed state (sealing state);

when water is boiled, when the temperature of water in the cup body reaches 95-100 ℃, the internal pressure is gradually increased, and meanwhile, the sealing gasket 410 is pushed open due to the pressure, so that the pressure relief effect is achieved.

After boiling water, along with the inside temperature decline of cup body 100, sealed the pad 410 can receive spring 420 pressure oneself to close when the temperature reaches 45 degrees, plays sealed effect, portable after sealed.
