The inner cover and the lining can be detached from the cover body, and the pressure control mechanism can be detached from the inner cover, so that the pressure control mechanism, the inner cover and the lining can be cleaned conveniently, a better cleaning effect is achieved, and bacteria are prevented from breeding.
When the electric pressure cooker works, the pressure limiting channel is sealed and closed by the pressure limiting sealing piece, and then food materials in the cooking cavity are pressurized and heated. When the pressure in the electric pressure cooker reaches a set value and needs to exhaust, or when the cooking is finished and high-temperature and high-pressure gas needs to be exhausted, the pressure limiting sealing piece is controlled to release the sealing, so that the pressure limiting channel is opened, and the high-temperature and high-pressure gas in the cooking cavity is exhausted from the exhaust channel to the external environment.
In some embodiments, the pressure control mechanism includes a safety valve assembly removably coupled with the inner cap, the safety valve assembly including: the safety joint is provided with a safety channel in a penetrating way, and the safety channel is communicated with the cooking cavity and the exhaust channel; the safety sealing piece is movably arranged on the safety joint and is used for closing or opening the safety channel.
It should be noted that the safety valve assembly is not operated at ordinary times, i.e. no exhaust. When the electric pressure cooker needs to exhaust, the high-temperature high-pressure gas in the cooking cavity is preferentially exhausted from the pressure limiting channel. When the pressure limiting channel is blocked and the pressure in the cooking cavity reaches a set value, the safety valve component starts to work in order to prevent the pressure from rising continuously, and the safety channel is opened by controlling the safety sealing piece to release the sealing, so that the high-temperature high-pressure gas in the cooking cavity is discharged through the safety channel.
In some embodiments, the safety valve assembly further comprises: the support ring is arranged in the safety channel and used for supporting the safety sealing element, and the support ring and the safety sealing element are arranged in a sealing way; the connecting rod penetrates through the safety channel, one end of the connecting rod is connected with the safety sealing piece, and the other end of the connecting rod is provided with a bracket capable of movably penetrating through the safety channel; the safety elastic piece is sleeved on the connecting rod and positioned between the supporting ring and the bracket, and is used for resetting the safety sealing piece to close the safety channel.
It should be noted that, when the pressure limiting valve assembly is not working and the pressure in the cooking cavity reaches the set value, the air pressure acting force is greater than the elastic force of the safety elastic piece. Therefore, the support moves towards the direction away from the cooking cavity under the action of air pressure, the safety sealing element is driven by the connecting rod to move, so that the contact gap between the safety sealing element and the support ring is enlarged, the sealing of the safety channel is relieved, the air in the cooking cavity can flow through the gap, and at the moment, the safety elastic element is compressed between the support ring and the support; when the pressure in the cooking cavity is smaller than the set value, the air pressure acting force is smaller than the elastic force of the safety elastic piece. The safety elastic piece gradually returns to a natural state, so that the safety sealing piece is driven to reset to close the safety channel.
In some embodiments, the safety joint is threadably coupled to the inner cap.
In some embodiments, the pressure limiting joint is a cylinder with two hollow ends open inside; the pressure limiting valve assembly further comprises a valve cover sleeved on the pressure limiting joint, and a clamp spring is connected between the valve cover and the pressure limiting joint; the pressure limiting sealing piece is detachably arranged on the valve cover.
In some embodiments, the pressure limiting valve assembly further comprises a drive mechanism for controlling the pressure limiting seal to close or open the pressure limiting channel; the driving mechanism is arranged on the lining.
In some embodiments, the drive mechanism comprises: a push rod; the driving piece is used for controlling the push rod to push the valve cover so as to open the pressure limiting channel; the first elastic piece is connected to one end of the push rod, which is far away from the valve cover, and is used for resetting the push rod to close the pressure limiting channel.
When the electric pressure cooker needs to exhaust, the driving mechanism works, the driving piece controls the push rod to push the valve cover to drive the pressure limiting sealing piece to displace, so that the sealing state is relieved, the pressure limiting channel is opened, and high-temperature and high-pressure gas in the cooking cavity is exhausted from the pressure limiting channel; when the electric pressure cooker does not need to exhaust, the driving mechanism does not work, the first elastic piece drives the push rod to reset, and the valve cover drives the pressure limiting sealing piece to reset under the action of the clamp spring, so that the pressure limiting channel is sealed and closed.
In some embodiments, the pressure limiting seal includes a conical portion sealingly disposed in the pressure limiting channel, the conical portion extending at least partially into the pressure limiting channel.
It is easy to understand that when the junction of pressure limiting sealing piece and pressure limiting passageway is the circular cone portion, the push rod promotes the valve gap and can drive pressure limiting sealing piece and produce the displacement, and circular cone portion extends to pressure limiting passageway at least partially, and when pressure limiting sealing piece atress is great, the circular cone portion that extends to pressure limiting passageway can with pressure limiting passageway inner wall butt to prevent that pressure limiting sealing piece from breaking away from the pressure limiting joint, produce the potential safety hazard.
In some embodiments, the pressure limiting valve assembly further comprises an anti-blocking cover detachably arranged on one side of the pressure limiting joint close to the cooking cavity; the anti-blocking cover is provided with a plurality of first through holes, and the first through holes are communicated with the cooking cavity and the exhaust channel.
