Description

Technical Field

[0001] This utility model relates to the field of pot lid technology, and in particular to a pressure pot lid with a rotatable reset exhaust valve. Background Technology

[0002] An electric pressure cooker is a type of kitchen appliance. Due to its advantages such as good cooking effect, speed, and energy saving, electric pressure cookers have entered thousands of households and become one of the essential kitchen appliances. After cooking, users can manually operate the pressure release valve to quickly release the pressure inside the pot, ensuring safe and fast cooking.

[0003] For example, patent CN217592544U discloses a cooking appliance that can switch between the functions of an electric pressure cooker and a rice cooker, comprising: an outer pot, an inner pot disposed inside the outer pot, a lid disposed at the opening of the outer pot, an exhaust valve and a lever disposed on the lid, a lever disposed between the exhaust valve and the lever, one end of the lever being disposed at the bottom end of the exhaust valve, the other end of the lever being disposed at the bottom end of the lever, a slider disposed on the lever, when the slider slides and presses against one end of the lever, the other end of the lever lifts up and opens the exhaust valve; when the slider slides away from one end of the lever, the other end of the lever moves away from the bottom end of the exhaust valve, and the exhaust valve falls down and closes.

[0004] The problem with the above technology is that the exhaust valve on the lid can be opened by sliding the lever with a toggle, but it needs to be manually reset to close. Users may forget to manually reset the toggle, leaving the exhaust valve in the open position, which poses a certain danger when using an electric pressure cooker.

[0005] To address this issue, a pressure cooker lid with a rotating reset exhaust valve is proposed. Utility Model Content

[0006] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a pressure cooker lid that can rotate to reset the exhaust valve, and automatically close the exhaust valve when the lid is rotated to the locked state.

[0007] The technical solution adopted by this utility model to solve the problem is: a pressure cooker lid with a rotatable reset exhaust valve, including a lid body and a pot edge. The lid body covers the pot edge, and a stop block is provided on the pot edge. An exhaust valve and a button that can move back and forth are movably arranged on the lid body. A lever is provided between the exhaust valve and the stop block. The front and rear ends of the lever are respectively drivenly connected to the rear ends of the exhaust valve and the stop block. A limiting pin that can move up and down is elastically connected to the lid body. The limiting pin is located at the front end of the button. A protrusion is provided on the limiting pin. The lower end of the limiting pin extends downward to the outside of the lid body. A limiting hole is provided at the front end of the button. A reset rod that can move in the back and forth direction is elastically arranged between the button and the lid body.

[0008] As a further improvement to the above technical solution, the button includes a connecting block, which is fixedly connected to the rear end of the reset rod, and the left and right ends of the connecting block abut against the rear ends of the lever and the button, respectively.

[0009] As a further improvement to the above technical solution, the lever is provided with an arc-shaped surface, and the left end of the connecting block abuts against the arc-shaped surface.

[0010] As a further improvement to the above technical solution, a bearing seat is provided on the cover, and a shaft is provided on the lever, with the shaft passing through the bearing seat.

[0011] As a further improvement to the above technical solution, the rear end of the button extends downward to form a vertical portion, and the lower end of the vertical portion extends laterally to form a horizontal portion. The limiting hole is disposed on the horizontal portion, the vertical portion is located beside the limiting pin, and the horizontal portion is located below the limiting pin.

[0012] As a further improvement to the above technical solution, the limiting pin has an L-shaped cross-section, the protrusion is provided at the bottom of the limiting pin, and the bottom of the limiting pin extends downward to an abutting part, which extends to the outside of the cover and can abut against the stop block.

[0013] As a further improvement to the above technical solution, a float valve is provided on the cover, and a through hole is provided on the reset rod, with the float valve located below the through hole.

[0014] The beneficial effects of this utility model are: there are two states between the lid and the edge of the pot: locked and unlocked. In the unlocked state, the limit pin disengages from the stop block, the button can move forward, the rear end of the button can slide and squeeze the rear end of the lever and make it rotate, so that the front end of the lever will lift up and open the exhaust valve, the limit hole moves forward with the button and engages with the protrusion, and the reset rod moves forward with the button and is compressed.

[0015] When the cover is rotated to the locked state, the stop block abuts against the limit pin and pushes the limit pin to move upward. The protrusion moves upward with the limit pin and disengages from the limit hole. The reset rod can move backward to reset and drive the button to move backward, so that the front end of the lever is reset and the exhaust valve is closed.

[0016] The pressure cooker lid is easy to operate and prevents users from forgetting to reset the exhaust valve. Attached Figure Description

[0031] The edge of the pot is fixedly mounted on the pressure cooker, and the lid and the edge of the pot have two states: locked and unlocked.

[0032] In the unlocked state, the limit pin 6 disengages from the stop block 21, the button 3 can move forward, the rear end of the button 3 can slide and squeeze the rear end of the lever 5 and make it rotate, so that the front end of the lever 5 will lift and open the exhaust valve 4, the limit hole 31 moves forward with the button 3 and engages with the protrusion 61, and the reset rod 7 moves forward with the button 3 and is compressed.

[0033] When the lid 1 is rotated to the locked state, the stop block 21 abuts against the limit pin 6 and pushes the limit pin 6 to move upward. The protrusion 61 moves upward with the limit pin 6 and disengages from the limit hole 31. The reset rod 7 can move backward to reset and drive the button 3 to move backward, so that the front end of the lever 5 is reset and the exhaust valve 4 is closed. This pressure cooker lid is easy to operate. The exhaust valve 4 can be closed by rotating the lid 1 to the locked state, which can prevent the user from forgetting to reset the exhaust valve 4 during the use of the pressure cooker.

[0034] In a preferred embodiment, the button 3 includes a connecting block 32, which is fixedly connected to the rear end of the reset rod 7. The left and right ends of the connecting block 32 abut against the rear ends of the lever 5 and the button 3, respectively.

[0037] In a preferred embodiment, the rear end of the button 3 extends downward to form a vertical portion 33, and the lower end of the vertical portion 33 extends laterally to form a horizontal portion 34. A limiting hole 31 is disposed on the horizontal portion 34, the vertical portion 33 is located beside the limiting pin 6, and the horizontal portion 34 is located below the limiting pin 6.

[0038] In a preferred embodiment, the limiting pin 6 has an L-shaped cross section, a protrusion 61 is provided at the bottom of the limiting pin 6, and an abutment portion 62 extends downward from the bottom of the limiting pin 6. The abutment portion 62 extends to the outside of the cover 1 and can abut against the stop block 21.

[0039] In a preferred embodiment, a float valve (not shown in the figure) is provided on the cover 1, and a through hole 71 is provided on the reset rod 7, with the float valve located below the through hole 71;

[0040] When the lid 1 is rotated to the locked state and the pressure cooker is activated, the gas pressure inside the pressure cooker will increase, causing the float valve to rise and pass through the through hole 71. At this time, the float valve can restrict the movement of the reset rod 7, so that the user cannot open the exhaust valve 4 by the button 3, thus preventing the gas inside the pressure cooker from scalding the user.

[0041] The structure of the aforementioned float valve is disclosed in publication number CN206473181 U, and will not be repeated here.
