Problems solved by technology

[0004] However, since this automatic reset pressure relief device works when the normal pressure relief protection devices fail, and the failure of the normal pressure relief protection devices indicates that the electric pressure cooker has a fault or a potential safety hazard, such as due to exhaust The pressure in the pot cannot be released normally due to reasons such as channel blockage, etc.
Obviously, this automatic reset pressure relief device does not solve the faults or potential safety h

Embodiment Construction

[0033] The present invention provides a kind of pressure relief valve aiming at the foregoing status of the prior art, for example, it can be used to replace the safety pressure relief device in the prior art, and its preferred structure is as follows Figure 1-5 shown.

[0034] The pressure relief valve of the present invention includes a valve body 1 and a valve core 2 , and the valve core 2 is slidably fitted in the valve body 1 . For example, a valve cavity is provided inside the valve body 1, and at least a part of the valve core 2 is slidably fitted in the valve cavity. Since the valve core 2 can slide relative to the valve body 1, the valve core 2 can have a first position and a second position, that is, the valve core 2 can slide between the first position and the second position. Wherein, the pressure relief valve is closed when the spool 2 is in the first position (see Figure 4 ), the pressure relief valve is opened when the spool 2 is in the second position (see ...

Abstract

The invention discloses a pressure release valve. The pressure release valve comprises a valve body and a valve element, the valve element is slidably assembled in the valve body and slides between a first position and a second position, when the valve element is located at the first position, the pressure release valve is closed, and when the valve element is located at the second position, the pressure release valve is opened; the valve body is provided with an elastic limiting structure, a groove is formed in the outer surface of the valve element, and when the valve element is located at the second position, the elastic limiting structure is embedded into the groove. After the pressure is released, the pressure release valve cannot reset automatically, safety of a cooking utensil applying the pressure release valve in the using process is guaranteed, meanwhile, a user can be reminded of conducting maintenance on the cooking utensil, and thereby use safety of the user is guaranteed. The invention further discloses a pot cover provided with the pressure release valve and an electric pressure cooker.

Description

technical field [0001] The invention relates to the field of cooking utensils, in particular to a pressure relief valve. The invention also relates to a pot cover with the pressure relief valve and an electric pressure cooker. Background technique [0002] At present, in order to ensure the safety of the electric pressure cooker in the cooking process, the pot cover of the electric pressure cooker is generally provided with a safety pressure relief device. Its function is that if the normal pressure relief protection device in the pot has failed, the pressure in the pot If the pressure in the pot cannot be overflowed normally, the pressure in the pot will increase. When the pressure in the pot increases to exceed the rated pressure limit value, the safety pressure relief device will act as the final protection measure to discharge the pressure in the pot and prevent the pot from being overpressured. Great danger. [0003] The safety pressure relief device of the electric p...
