Description
Technical Field
The invention relates to a pressure cooker, in particular to a handle opening and closing mechanism for the pressure cooker.
Background
Because the inside of a pressure cooker in the market is in a high-pressure state, the cooker cover can be opened only after pressure in the cooker is released before the cooker cover is opened, the pressure is released through a steam release valve in the conventional pressure release mode, and the pressure release process generally consumes a long time; in addition, the steam vent is too small and is easily blocked by food materials, so that gas cannot be effectively exhausted, pressure cannot be released, and the purpose of pressure relief cannot be achieved.
Disclosure of Invention
The invention provides a handle opening and closing mechanism aiming at the problems existing in the prior art when the pressure cooker is decompressed.
In order to solve the technical problem, the invention is solved by the following technical scheme:
handle switching mechanism is equipped with the driving lever including fixing the last handle on the pot cover on the last handle, and one end of driving lever articulates on last handle, and the other end can rotate around the hinged end for application of force end and driving lever, is connected with on the driving lever to pass in the pot cover lateral wall and can promote the push rod of the interior rubber circle of pot cover.
Preferably, one end of the upper surface of the upper handle close to the pot cover is a concave platform, the shifting rod is arranged in the concave platform, and the side wall of the concave platform is a blocking wall for limiting the shifting rod.
Preferably, the upper surface of the upper handle is provided with a sliding chute for the push rod to slide, and the length direction of the sliding chute is matched with the motion track direction of the push rod. The effect of spout can carry on spacingly, the direction to the push rod, guarantees that the push rod can be stable, promote the rubber circle smoothly.
Preferably, the force application end of the deflector rod extends out of the upper handle, a step-shaped concave shoulder is formed at the lower end part of the side wall of the upper handle, a convex block clamped into the step-shaped concave shoulder is arranged on the end face, close to the side wall of the upper handle, of the force application end of the deflector rod, and the convex block can reciprocate in the step-shaped concave shoulder. The lug can realize spacing the driving lever rotation track with the cooperation of step form concave shoulder, makes the driving lever block on last handle simultaneously, guarantees going on smoothly of this pressure release mechanism motion process.
Preferably, a spring hole is further formed in the force application end of the shifting rod, the end face, close to the side wall of the upper handle, of the shifting rod, a spring is fixed in the spring hole, the end portion of the spring extends out of the spring hole, the end portion of the spring is connected with a steel ball, and two clamping grooves for the steel ball to be clamped into are formed in the side wall of the upper handle along the motion direction of the force application end of the shifting rod. The cooperation of steel ball and draw-in groove can be with the driving lever spacing in required position, realizes the continuous stable pressure release of driving lever.
Preferably, the end face, close to the side wall of the upper handle, of the force application end of the shifting lever is in an arc groove shape, so that an operator can apply force to the force application end more reasonably.
Preferably, the pot also comprises a lower handle fixed on the pot body, and the force application end of the deflector rod extends downwards to form a protruding part which can abut against the side wall of the lower handle; one end of the lower handle close to the pan body is provided with a lower handle concave shoulder for the convex part to move from one side of the lower handle to the other side. The protruding part can be tightly abutted against the side wall of the lower handle, the relative position of the upper handle and the lower handle can be limited to a certain extent, and the deflector rod can be further limited to a required position; and because the setting of bulge to make when the driving lever is in the state that does not promote the rubber circle, go up handle and the unable relative movement of lower handle, can't uncap this moment promptly, only be in the position that the concave shoulder of lower handle corresponds when the bulge, the driving lever drives the position that the push rod promoted the rubber circle promptly, just can make the bulge move along the concave shoulder of lower handle, just can make handle and lower handle relative motion this moment, open the pot cover, effectively improve the security performance of the pot body.
Preferably, the upper surface of the upper handle is provided with a hinge hole, and the hinge end of the deflector rod is provided with a rotating column which can be inserted into the hinge hole and can rotate in the hinge hole. Through the form that rotates post and hinge hole complex, can effectively avoid the driving lever to break away from the upper handle for the transmission between driving lever and the upper handle is more stable.
Preferably, the handle further comprises a cover plate fixed at the upper end of the upper handle, and the positions of the cover plate corresponding to the two clamping grooves are marked with opening and closing marks. The cover plate can play a role in protecting the pressure relief mechanism, and the mark on the cover plate can enable an operator to clearly know whether the pressure relief mechanism is in a pressure relief state.
The utility model provides a pressure cooker, includes the pot body and pot cover, still includes aforementioned handle mechanism that opens and shuts, and it can realize high efficiency pressure release, does not have the problem that the interior material object of pot blockked up the pressure release hole simultaneously yet.
Due to the adoption of the technical scheme, the invention has the remarkable technical effects that:
according to the invention, the pressure relief mechanism arranged in the handle pushes the rubber ring in the cooker cover, so that the rubber ring is partially separated from the inner wall of the cooker cover, the pressure in the cooker body can be released from a gap between the cooker cover and the cooker body, the pressure relief mode is very simple, the pressure can be quickly and efficiently relieved, and meanwhile, the problem that a pressure relief hole is blocked by a real object in the cooker is avoided.
