Description

Technical Field

[0001] This utility model relates to the field of cooking utensil technology, and in particular to a pressure cooker lid exhaust device. Background Technology

[0002] Traditional pressure cookers require manual operation or the use of tools to lift the pressure relief valve, which can easily cause burns from the high-temperature steam, making it inconvenient and slow. Therefore, to improve safety and user experience, modern pressure cookers typically have a separate adjustment switch or knob on the lid, away from the pressure relief valve, to prevent burns.

[0003] For example, Chinese utility model patent CN208114489U discloses a pressure relief structure for a pressure cooker, including a valve body, a lever, and a knob. The left side of the lever is connected to the valve body, and the right side moves up and down with the rotation of the knob. All or part of the valve body moves up and down with the left side of the lever. The knob has a circumferentially inclined upward sliding groove. The right side of the lever inserts into the sliding groove and moves along the groove direction. The lever connects the valve body and the knob, allowing a person to simply rotate the knob to raise the valve body and relieve pressure. The existing technology has the problem that the connection between the lever and the sliding groove is not stable enough; the knob may hit the lever during rotation, causing jamming. It also has many parts and low durability. Therefore, the existing technology needs improvement. Utility Model Content

[0004] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a pressure cooker lid exhaust device with a simple and stable structure and smooth operation.

[0005] The technical solution adopted by this utility model to solve the problem is: a pressure cooker lid exhaust device, including: a pressure cooker lid, a rotating part, a lever and a pressure relief valve. During the rotation of the rotating part, one end of the lever can be pressed down and the other end of the lever can be swung upward to lift the pressure relief valve.

[0006] A positioning sleeve is fixedly connected to the pressure cooker lid. The top of the positioning sleeve is provided with an annular portion, and the bottom of the annular portion is provided with a downwardly inclined rail.

The buckle passes vertically through the annular part and is fastened to the inclined rail. A top rod is provided at the center of the rotating component.

[0008] Rotating the rotating component causes the buckle to move along the inclined rail and slide the rotating component downwards, pressing against the pressure end of the lever and controlling the opening and closing of the pressure relief valve.

[0009] As a further improvement to the above technical solution, the bottom end of the buckle is folded outward to form an edge, the edge is closely fitted with the inclined rail, and one side of the edge is provided with a beveled surface adapted to the inclined rail.

[0010] As a further improvement to the above technical solution, the inclined rail includes an inclined section and a straight section, with the straight section connected to the lowest point of the inclined section.

[0011] As a further improvement to the above technical solution, the bottom of the annular portion is provided with a bottom end face, and the outer ring of the bottom end face is provided with spaced connecting grooves. The number of connecting grooves matches the number of buckles, and each buckle is inserted into the connecting groove.

[0012] As a further improvement to the above technical solution, a sliding sleeve is connected to the bottom of the bottom end face, a step is provided inside the sliding sleeve, the top rod is inserted into the sliding sleeve, a spring is provided between the rotating part and the step, and the spring is sleeved on the top rod.

[0013] As a further improvement to the above technical solution, the positioning sleeve is fixedly connected to an outer shell, the outer shell is fixedly connected to the pressure cooker lid, and the positioning sleeve is provided with a switch mark.

[0014] The beneficial effects of this utility model are as follows: By setting a positioning sleeve that is fixedly connected to the pot lid, the bottom of the positioning sleeve is provided with an inclined rail pointing downwards, and the bottom of the rotating part is provided with a buckle and a push rod. The buckle is fastened to the inclined rail, and a spring is sleeved on the push rod. When the rotating part is rotated, the buckle moves along the inclined rail, causing the rotating part to slide down. The push rod presses down on the lever, lifting the pressure relief valve to release pressure, and the rotating part rotates in the opposite direction. Under the action of the spring, the rotating part quickly returns to its original position. The positioning sleeve serves to fix the rotating part and guide it. The structure is simple and stable, and it is smooth to use. Attached Figure Description
