It can be understood that in the use process of the traditional electric cooker, the high-pressure and high-temperature steam generated by the inner cavity of the cooker body is directly discharged to the outside or discharged to the outside through the micro-pressure air valve, and the steam inevitably transmits heat to the outer shell of the cooker cover while being discharged, so that the outer shell of the cooker cover is continuously heated, and a user can be scalded when contacting the outer shell of the cooker cover. The cooker cover 200 of the utility model is also provided with the heat insulation cavity 240 communicated with the outside atmosphere, the heat insulation cavity 240 can play a role in heat insulation and heat dissipation, part of heat is transferred to the inner cover 220 when the high-pressure high-temperature steam generated in the inner cavity 110 passes through the pressure cavity 250, and the heat transferred to the inner cover 220 can be cooled or dissipated to the outside atmosphere through the heat insulation cavity 240, so that the outer cover 210 (namely the outer shell of the cooker cover 200) cannot be heated or the temperature cannot be obviously raised, and a user cannot be scalded when contacting the outer cover 210.

Specifically, referring to fig. 5, the outer cover 210 is provided with a pressure relief hole 211, the pot cover 200 further includes a grip 260, the grip 260 is convexly disposed on the outer surface of the outer cover 210 and forms a pressure relief cavity 270, the pressure relief cavity 270 is communicated with the pressure relief hole 211, a channel through which gas passes is formed between the edge of the grip 260 and the outer surface of the outer cover 210, the pressure relief cavity 270 is communicated with the outside through the channel, and the number of the pressure relief holes 211 can be one, two, three, four, etc. In this embodiment, the edge of the grip 260 has a gap with the outer surface of the outer cap 210, which gap forms a channel for the passage of gas.

Referring to fig. 6, the pot cover 200 is provided with an exhaust hole 280 penetrating the outer cover 210 and the inner cover 220 in a thickness direction thereof, the exhaust hole 280 is communicated with the outside atmosphere, the exhaust hole 280 extends to the pressure chamber 250 across the heat insulation chamber 240, and the exhaust hole 280 is not communicated with the heat insulation chamber 240. I.e., the pressure chamber 250 is in communication with the outside atmosphere through the vent 280, while the pressure chamber 250 is not in communication with the insulating chamber 240. If the pressure chamber 250 is in communication with the insulating chamber 240, the high pressure and high temperature steam generated by the inner chamber 110 will enter the insulating chamber 240 from the pressure chamber 250, so that the insulating chamber 240 will continuously heat up, and the insulating chamber 240 will lose the heat-insulating and heat-dissipating effects as mentioned above. Specifically, the exhaust hole 280 includes a first hole 281 and a second hole 282, the first hole 281 is formed in the outer cap 210, the second hole 282 is formed in the inner cap 220, and the gas in the pressure chamber 250 can be sequentially exhausted to the external atmosphere through the second hole 282 and the first hole 281.

When two different food materials are simultaneously placed in the two inner cavities 110 of the electric cooker 10, the boiling or boiling time of the two food materials is different, the air pressures in the two inner cavities 110 are also different in the cooking process, and the air pressures of the food materials in the two inner cavities 110 can be not interfered with each other by the two pressure cavities 250. It will be appreciated that in other embodiments, the number of the pressing caps 230 may be one, and the pressing caps 230 may be sealingly connected to the inner cap 220 and enclose two pressure chambers 250 that are not in communication with each other.

Further, the rice cooker 10 further includes a gasket 400, the gasket 400 is disposed at an outer edge of the pressing cover 230, and the gasket 400 can seal the two inner cavities 110 such that the two inner cavities 110 are not communicated with each other. When the two inner cavities 110 of the electric cooker 10 cook different food materials simultaneously, the gas in the two inner cavities 110 can infiltrate each other through the gap between the gland 230 and the cooker body 110, so that the food materials in the two inner cavities 110 are mixed with each other, and the cooking effect is affected. The sealing gasket 400 is provided to seal the inner cavities 110 so that the two inner cavities 110 are not communicated with each other, and the problem of odor tainting can be effectively avoided. Meanwhile, the number of gaskets 400 corresponds to the number of the pressing caps 230, that is, when the number of the pressing caps 230 is one, the number of the gaskets 400 is also set to one accordingly.

It will be appreciated that when the air pressure in the inner cavity 110 is smaller than the gravity of the micro-pressure air valve 231, the cover portion 231a covers and closes the mounting hole 232, the pressure chamber 250 is not communicated with the inner cavity 110, when the air pressure in the inner cavity 110 is larger than the gravity of the micro-pressure air valve 231, the air in the inner cavity 110 can push the micro-pressure air valve 231 to move along the axial direction of the mounting hole 232 to open the micro-pressure air valve 231, the pressure chamber 250 is communicated with the inner cavity 110, and the air in the inner cavity 110 can enter the pressure chamber 250 from the gap between the movable shaft 231b and the mounting hole 232.

Further, in an embodiment, the gland 230 is further provided with air holes 233, the air holes 233 and the mounting holes 232 are arranged in parallel, and the covering portion 231a can cover the air holes 233, when the air in the pressure chamber 110 pushes the micro-pressure air valve 231 to move along the axial direction of the mounting holes 232, the air holes 233 are communicated with the pressure chamber 250 and the inner chamber 110, at this time, the air holes 233 can play a role in accelerating the exhaust, and the number of the air holes 233 can be one, two, three, four, etc. It will be appreciated that in other embodiments, the gland 230 may not be provided with the air holes 233 without regard to improving the venting efficiency.

In one embodiment, the gland 230 is provided with a relief aperture 234 communicating the pressure chamber 260 with the inner chamber 110, the aperture of the relief aperture 234 being smaller than the aperture through which gas passes when the micro-pressure gas valve 231 is opened. When the micro-pressure air valve 231 cannot be normally opened due to blockage, jamming and the like of food residues, the high-temperature and high-pressure air in the inner cavity 110 can still enter the pressure cavity 250 from the safety hole 234 and then be discharged to the outside atmosphere through the air discharge hole 280. It will be appreciated that in other embodiments, the gland 230 may not be provided with the safety hole 234, and when the micro-pressure valve 231 cannot be opened due to failure, the gas generated in the inner cavity 110 may continuously accumulate in the inner cavity 110, resulting in damage to the electric rice cooker 10.
