Abstract
The utility model relates to a cooker lid of a pressure cooker, which comprises a safety valve arranged on the cooker lid, a pressure limiting valve, a clog preventing cover and a hand lever, and a latching mechanism composed of a press-button, a spring, a latching valve, a lever, a locking pin, etc. is arranged in an inner cavity of the hand lever; simultaneously, the cooker lid is arranged into a shape with an inwards concave middle part. The latching mechanism ensures that the press-button is must first pressed before opening the cooker lid, when pressure in the cooker does not reach safe pressure, the press-button can not be pressed and the cooker lid can not be opened, avoiding the malfunction of the pressure limiting valve or harm as a result of being anxious to open the cooker lid and having very high using safety. The inwards concave cooker lid can store overflowed food soup during air injection and water formed by liquefaction, which is convenient to clean in time and to prevent the periphery of a cooker from being polluted.
Description
The utility model relates to kitchen utensils, especially pressure cooker lid.
Pressure cooker is the food boiling apparatus that every household possesses, it utilizes the steam pressure of sealing that food is boiled fast, because its boiling is ripe soon, the efficient height, by Modern Family's extensive use, and in order to ensure the security of use, safety valve and pressure limiting valve all are installed on the pressure cooker, however, because use misoperation or safeties are malfunctioning, the explosion accident of pressure cooker happens occasionally, personal safety is brought threat, require the user when the pressure limiting valve exhaust reaches safe pressure, must not open pot cover for this reason, but some user is former thereby be eager to uncap because of certain, perhaps pressure limiting valve is malfunctioning, all might damage.In addition, when pot inner pressure reached certain value, the pressure limiting valve blast pipe began exhaust, and steam in the pot is discharged outside the pot, and food and soup is overflowed in the exhaust course of injection makes pot unavoidably, or the water that liquefaction forms is dirty along pot cover, causes the kitchen range ambient contamination.
The purpose of this utility model is to avoid the defective of prior art and the pressure cooker lid that can't open pot cover when exhaust does not reach safe pressure in a kind of pot is provided is first purpose; It is second purpose that a kind of pressure cooker lid that stores food and soup is provided simultaneously.
According to above-mentioned purpose, embodiment of the present utility model is: this pressure cooker lid comprises pot cover, bead is provided with sealing ring in the pot cover, the place, upper edge is provided with safety valve, the top is provided with handle, the handle top is provided with the pressure limiting valve that links to each other with pot cover, the pressure limiting valve blast pipe stretches in the pot cover and is connected with Anti-stop cover, it is characterized in that described intracavity of handle is provided with latching device, this mechanism is provided with the button by spring reset on handle, the button pin lower end abutment that connects button is at lever one end that with lever dolly is hinged point, the other end of lever is connecting the lock pin that can insert pot cover, is provided with spring and is fixed on the latching valve that has pore on the pot cover between the lever below of relative key pin position and pot cover.
Described pot cover profile middle part is concave shaped, and handle coincide at the pot cover top.
This pressure cooker lid compared with prior art, owing to have latching device, want to open necessary first pressing one knob down of pot cover, only when exhaust reaches safe pressure, button just can be pressed down and open lock pin, pot cover just can be opened, like this with regard to avoided pressure limiting valve malfunctioning and cause open by mistake the harm that lid brings, have very high safety in utilization.Secondly, the moisture that food and soup that the concave inward structure of pot cover overflows when making pressure cooker jet and liquefaction form can be stored in recess, is convenient to timely cleaning, avoids kitchen range contaminated on every side.
To be described in detail again according to the embodiment of the accompanying drawing that provides below the utility model.
Pressure cooker lid comprises the pot cover (15) that covers with the sealing of pot body referring to accompanying drawing 1, and the interior bead of pot cover has the annular groove of an indent, and the flange of sealing ring (16) embeds in the annular groove, makes pressure cooker in use have good sealing.Place, pot cover upper edge is provided with safety valve (14), and the effect of safety valve is that when blast pipe is blocked by accident after pot inner pressure was elevated to a certain degree, safety valve energy releasing pressure automatically guaranteed the pressure cooker safe handling.
Pot cover profile middle part is concave shaped, and handle (1) coincide at the pot cover top, and the handle top is provided with the pressure limiting valve (11) that links to each other with pot cover, and pressure limiting valve blast pipe (12) stretches in the pot cover and is connected with Anti-stop cover (13), prevents that food from stopping up.
Intracavity of handle is provided with latching device, the handle of this mechanism has recess in, in be provided with the button (7) that resets by spring (9), button and button pin (8) are utilized mutual chimeric connection of elasticity of material, the button pin lower end abutment is being an end of the lever (4) of hinged point with lever dolly (5), the other end of lever links to each other with lock pin (2), this lock pin can insert in the pot cover corresponding aperture, pot cover can't be rotated, and when pot inner pressure did not reach the safe pressure of unlatching, air pressure can't move lever, promptly can't make lever action by twist pin, lock pin inserts all the time in the pot cover hole and pins, and boils to cover with much power this moment all can't open, and prevents that contingency from taking place.Be provided with spring (6) and be fixed on the latching valve (10) of being with pore on the pot cover between the lever below of relative key pin position and pot cover, steam pressure acts on the lever below simultaneously by latching valve pore and spring force in the pot, button can't be pressed down, lock pin can't be removed the snap close to pot cover, and pot cover just can not be opened and guarantee safety.
Can guarantee that in order to ensure the action of lever (4) lock pin (2) locks in the pot cover hole (15) smoothly, on the relevant position of pot cover, be provided with the prerotation vane (3) of lock pin activity.
