Problems solved by technology

[0004] That is, press a switch, lift the gravity valve (pressure relief valve) through the connecting rod, and the gravity valve will leave the sealing end surface of the exhaust pipe for exhausting. When the hand is away, the gravity valve is in contact with the sealing end surface of the exhaust pipe under the action of gravity, and is in a sealed state. This exhaust method is not safe, and the ejected steam is easy to burn the hand, because the button must be pressed all the time to exhaust

Embodiment 1

[0053] Such as Figure 1 to Figure 3Shown, a kind of pressure cooker comprises pot body 1 and pot cover 2, and pot body 1 comprises shell 11 and insulation cover 12, and insulation cover 12 is made of metal material, and insulation cover 12 is provided with pot liner 13, and pot liner 13 is used for To hold food, the outer edge of the upper end of the heat preservation cover 12 is provided with several pot teeth 121. The pot teeth 121 make the outer edge of the heat preservation cover 12 form a large round edge 122 and a small round edge 123 with different diameters. The outer edge of the tooth 121 is defined, and the so-called small round edge 123 is defined by the outer edge of the heat preservation cover 12 between the pot tooth 121 and the pot tooth 121 . The pot cover 2 is provided with buckle teeth, and the number of buckle teeth corresponds to the number of pot teeth 121. When the pot cover is fully closed, the buckle teeth on the pot cover 2 correspond to the positions...

Embodiment 2

[0070] In this embodiment, the structure of the latch device 31 is improved on the basis of Embodiment 1. Specifically, the latch device 31 is arranged on the pot body 1, and the stopper device 32 is arranged on the pot cover 2. The relative movement between the latch device and the stopper device 32 can be realized by toggling the latch device 31 , thereby realizing the locking and unlocking of the pot cover 2 .

Embodiment 3

[0072] In this embodiment, on the basis of Embodiment 1, the structural form of the pin head and the stopper device is improved. Specifically, the pin head and the stopper device can also be a toothed structure that can cooperate with each other, including a single tooth structure and multi-tooth structure, or other structures capable of meshing with each other.

Abstract

The invention provides a pressure cooker which comprises a cooker body and a cooker cover. An exhausting hole and a pressure relief valve are arranged on the cooker cover, and the pressure relief valve is arranged on the exhausting hole. The pressure cooker is also provided with a pressure relief driving device for driving at least part of pressure relief valve to break away from the exhausting hole, a switch device for controlling the pressure relief driving device and a switch reset device capable of switching from a closed state to an opened state. By arranging the pressure relief driving device, the switch device and the switch reset device, a pressure relief function can be achieved by shifting the switch device in the using process of a user, resetting of the switch device can be also automatically achieved in the uncovering process, and the user is prevented from forgetting opening the switch device.

Description

technical field [0001] The present invention relates to a cooking device, more particularly, to an electric pressure cooker. Background technique [0002] At present, the common electric pressure cooker on the market has a high air pressure in the pot after the food is cooked. There is a safety float on the pot cover that rises through the push rod hole on the push rod. It is impossible to open the lid, which plays a role of safety protection. However, if the user wants to add some condiments during the cooking process or quickly open the cover after the food is cooked, because it takes a long time for natural cooling and pressure reduction, manual exhaust must be performed. [0003] At present, manual exhaust usually adopts the following methods: [0004] That is to say, press a switch, lift the gravity valve (ie pressure relief valve) through the connecting rod, and the gravity valve leaves the sealing end face of the exhaust pipe for exhausting. The sealing ends of the...
