Safety opening-closing cover device of pressure cooker

Abstract

The invention provides a safety opening-closing cover device of a pressure cooker, which belongs to the technical field of cooking apparatuses and solves the problems of complex structure and complex operation of the opening-closing cover of the conventional pressure cooker. The safety opening-closing cover device of the pressure cooker comprises an upper handle fixed on a cooker cover and a lower handle fixed on a cooker body; the upper handle is internally provided with a safety push plate which can slide backwards and forwards in the upper handle, and the front end of the safety push plate is provided with a valve rod hole of an opening stop valve rod which can be inserted in the cooker cover when the safety push plate slides backwards and forwards; a spring is arranged between the safety push plate and the cooker cover, and one end of the spring abuts against the cooker cover and the other end abuts against the safety push plate; the lower part of the rear end of the safety push plate is provided with a retaining foot; the lower handle is provided with a chute, and when the upper handle circumferentially rotates to approach the lower handle, the retaining foot can be inserted into the chute to enable the safety push plate to slide forwards under the guiding of the chute; and the safety push plate is further provided with a safety structure which can leave a gap between the cooker cover and the cooker body when the cooker cover is inaccurately buckled. The invention has the advantages of convenient operation, safety, reliability and the like.

Description

technical field [0001] The invention belongs to the technical field of cooking utensils, and relates to a pressure cooker, in particular to a safety opening and closing cover device for a pressure cooker. Background technique [0002] In order to make the pressure cooker can be used normally and safely, a safety device is usually arranged on the opening and closing cover of the pressure cooker. The function of this safety device is: when the lid of the pressure cooker is not fastened to the body of the pot, the pressure in the pot cannot rise; when the lid of the pressure cooker is opened, if there is pressure in the pot, the lid cannot be opened. [0003] There are many types of safety devices for opening and closing lids of existing pressure cookers, and the specific operations are also different during use. Many structures have also been patented. Disclose a kind of pressure cooker air pressure automatic interlocking safety device [application number: 00208275.6] as Chi...

AI Technical Summary

Problems solved by technology

However, in this solution, when the lid and the body of the pot are not properly fastened, that is, when misoperation occurs, the pressure cooker will be boosted during heating, so there are potential safety hazards

In addition, the above solution still has a relatively complicated structure and is not particularly convenient to use. In the process of opening and closing the cover, the push plate needs to be pushed by hand to achieve the purpose of opening and closing the cover, which is relatively cumbersome to operate.
