Description

Valve body assembly, cover body assembly and cooking utensil Technical Field The invention relates to the technical field of small household appliances, in particular to a valve body assembly, a cover body assembly and a cooking utensil. Background The pressure cooking utensil generally comprises a pot body and a pot cover, wherein the pot body comprises a lining cover and a locking cover, the locking cover is provided with a cover tooth, and the cover body is connected with the pot body through the cover tooth and the pot tooth in the pressure cooking process. Simultaneously, the exhaust pipe is matched with a pressure limiting valve the pressure relief of the exhaust can be achieved. Specifically when cooking, put into the pot body with food, install the lid on the pot body to rotatory locking closure makes pot tooth and lid tooth butt cooperation, after cooking, exhaust pipe and pressure limiting valve are passed through to cooking utensil and pressure release, after the pressure release is accomplished, the lid makes pot tooth and lid tooth separation through rotatory mode, and then realizes uncapping. In the related art, in order to achieve rapid exhaust, a valve cavity and a sealing structure are generally provided on a cover body, and when the rapid exhaust is required, a solenoid valve drives the sealing structure to enable the sealing structure to open the valve cavity so as to achieve the exhaust. In the process, the gas in the valve cavity can be rapidly discharged and easily rushed to the electromagnetic valve, so that the process of driving the sealing structure to move by the electromagnetic valve is unstable, and the sealing structure is easily caused to block the valve cavity again, thereby influencing the exhaust efficiency. Disclosure of Invention The invention mainly aims to provide a valve body assembly, a cover body assembly and a cooking utensil, so as to solve the problems that steam is easy to rush to an electromagnetic valve during exhaust in the related art and the stability of a driving sealing structure of the electromagnetic valve is affected. In order to achieve the above object, according to one aspect of the present invention, there is provided a valve body assembly including a mounting seat, a valve body having a valve cavity and first and second openings communicating with the valve cavity, a sealing structure including a connecting rod movably penetrating the second openings and a sealing member disposed on the connecting rod, the sealing member being disposed in one-to-one correspondence with the plurality of second openings, a pushing member movably disposed on the mounting seat, the pushing member being capable of pushing the connecting rod to avoid the second openings when moved, and a reset member drivingly engaged with the connecting rod and capable of maintaining the sealing member in a position to close the second openings. By applying the technical scheme of the application, the valve body is provided with the valve cavity, and the first opening and the second opening which are communicated with the valve cavity, the sealing structure comprises the connecting rod and the sealing element, the connecting rod is movably arranged in the second opening in a penetrating way, the sealing element is arranged corresponding to the second opening, the pushing element is movably arranged on the mounting seat, and the resetting element is in driving fit with the connecting rod and can enable the sealing element to be kept at a position for blocking the second opening. With the above arrangement, fluid enters the valve chamber from the first opening and exits from the second opening, or fluid enters the valve chamber from the second opening and exits from the first opening. The pushing piece can drive the connecting rod to move so that the sealing piece avoids the second opening, at the moment, the second opening is opened, fluid can flow in or flow out, the pushing piece can increase the distance between the driving piece and the second opening, and then the influence of the fluid on the driving piece can be avoided, so that the driving process of the driving piece is more stable. Therefore, the technical scheme of the application effectively solves the problems that steam is easy to rush to the electromagnetic valve during exhaust in the related technology and influences the stability of the driving sealing structure of the electromagnetic valve. Further, the valve body assembly further comprises a limiting structure, the limiting structure is arranged between the mounting seat and the pushing piece, and when the pushing piece moves towards the direction away from the valve body, the limiting structure can prevent the pushing piece from being separated from the mounting seat. The setting of limit structure can make the position of impeller more stable, can prevent that the impeller from excessively moving towards the direction of keeping away from the valve body. Further, lim
