Abstract
The utility model relates to a kitchen cooking vessel, particularly a pressure cooker with an explosion-proof integrated pressure-limiting device. A pressure limiting valve and an air nozzle of the utility model are provided with mutually matched screw threads capable of screwing in or out of the air nozzle. Due to the adoption of the integrated design of the pressure limiting valve and the air nozzle, the utility model has the advantage of convenient operation without exploding the pressure limiting valve, thoroughly solving the problems of the easily exploding pressure limiting valve and the lost pressure limiting valve in terms of structural design.
Description
The utility model step reaches a kind of kitchen cooking utensil, particularly a kind of pressure cooker that has the quick-fried integrated pressure limiting device of erosion control.
The pressure limiting device of existing pressure cooker comprises pressure limiting valve, air nozzle and exhaust nut, air nozzle is installed on the pot cover of pressure cooker by the exhaust nut, the steam vent that communicates with air nozzle is arranged on the exhaust nut, its air nozzle and pressure limiting valve all are to adopt straight barrel type air nozzle and pressure limiting valve, be that pressure limiting valve is straight up and down on air nozzle, the pressure limiting device of this structure exists following weak point:
1, pressure limiting valve is easily towards quick-fried: the steam vent that communicates with air nozzle on the exhaust nut usually can be blocked and cause the pressure cooker internal pressure to rise, when the pressure in the pressure cooker rises to when to a certain degree breaking through the tamper that is blocked on the exhaust nut steam vent, pressure in the pressure cooker can make pressure limiting valve towards quick-fried and fly away from air nozzle at a high speed, causes article to damage or casualty accident;
2, use inconvenient: because pressure limiting valve often is in released state with air nozzle, the user usually can forget that the placement of pressure limiting valve is local and can not find pressure limiting valve, even loses pressure limiting valve, thereby makes troubles to the user of pressure cooker.
In order to solve pressure limiting valve easily towards quick-fried problem; Chinese patent CN2207778Y has announced a kind of pressure cooker anti-explosion safety protective valve that is installed on the exhaust nut; though it has alleviated pressure limiting valve to a certain extent easily towards quick-fried problem, but still can not on structural design, thoroughly solve pressure limiting valve easily towards quick-fried problem.
One of the purpose of this utility model is to overcome the above-mentioned weak point of prior art and provide a kind of pressure cooker erosion control quick-fried integrated pressure limiting device.
The technical scheme that realizes above-mentioned purpose of the present utility model is: the quick-fried integrated pressure limiting device of pressure cooker erosion control comprises pressure limiting valve, air nozzle and exhaust nut, air nozzle is installed on the pot cover of pressure cooker by the exhaust nut, the steam vent that communicates with air nozzle is arranged on the exhaust nut, have on pressure limiting valve and the air nozzle cooperatively interact, pressure limiting valve can be on air nozzle the screw thread of precession or back-out.
Another technical scheme that realizes the utility model above-mentioned purpose is that the quick-fried integrated pressure limiting device of pressure cooker erosion control comprises pressure limiting valve, air nozzle and exhaust nut, air nozzle is installed on the pot cover of pressure cooker by the exhaust nut, the steam vent that communicates with air nozzle is arranged on the exhaust nut, the protruded object and the groove that cooperatively interact, pressure limiting valve can only be loaded onto or take off at the ad-hoc location of air nozzle are arranged on pressure limiting valve and the air nozzle.
The further technical scheme that realizes the utility model above-mentioned purpose is: described groove is a curved slot.
Realize that two of the purpose of this utility model is to overcome the deficiencies in the prior art part and a kind of pressure cooker that has the quick-fried integrated pressure limiting device of erosion control is provided.
The technical scheme that realizes the purpose that the utility model is above-mentioned is: the pressure cooker that has the quick-fried integrated pressure limiting device of erosion control is made up of pot body and pot cover, equal jug on pot body and the pot cover, also have pressure limiting device and safeties on the pot cover, pressure limiting device comprises pressure limiting valve, air nozzle and exhaust nut, air nozzle is installed on the pot cover of pressure cooker by the exhaust nut, the steam vent that communicates with air nozzle is arranged on the exhaust nut, have on pressure limiting valve and the air nozzle cooperatively interact, pressure limiting valve can be on air nozzle the screw thread of precession or back-out.
Another technical scheme that realizes the utility model above-mentioned purpose is that the pressure cooker that has the quick-fried integrated pressure limiting device of erosion control is made up of pot body and pot cover, equal jug on pot body and the pot cover, also have pressure limiting device and safeties on the pot cover, pressure limiting device comprises pressure limiting valve, air nozzle and exhaust nut, air nozzle is installed on the pot cover of pressure cooker by the exhaust nut, the steam vent that communicates with air nozzle is arranged on the exhaust nut, the protruded object and the groove that cooperatively interact, pressure limiting valve can only be loaded onto or take off at the ad-hoc location of air nozzle are arranged on pressure limiting valve and the air nozzle.
Realize that the further technical scheme of the utility model above-mentioned purpose is: described groove is a curved slot.
The utility model compared with prior art, has following advantage owing to adopt as above design:
1, pressure limiting valve is not towards quick-fried: could take off from air nozzle when ad-hoc location because pressure limiting valve need rotate a tame angle or need, even raise because of obstruction makes the pressure cooker internal pressure, can not make pressure limiting valve because of towards the quick-fried air nozzle that leaves yet, pressure limiting valve is dashed from the top of air nozzle exhaust outlet and exhaust pressure relief fast, after the pressure cooker internal pressure lowered, pressure limiting valve was just because of the own wt self-return.
2, easy to use: as, not need when normally using pressure limiting valve is taken off from air nozzle, so can not can not find or lose pressure limiting valve because of pressure limiting valve and air nozzle are the integrated design.
Below in conjunction with drawings and Examples detailed structure of the present utility model is further described.
Accompanying drawing 1 is the structural representation of the utility model embodiment 1;
Accompanying drawing 2 is the pressure limiting valve inner surface expanded view of the utility model embodiment 2;
Accompanying drawing 3 is the air nozzle outwardly deploying figure of the utility model embodiment 2;
Embodiment 1
As shown in Figure 1: the quick-fried integrated pressure limiting device of pressure cooker erosion control comprises pressure limiting valve (1), air nozzle (2) and exhaust nut (3), air nozzle is installed on the pot cover (4) of pressure cooker by the exhaust nut, the steam vent (5) that communicates with air nozzle is arranged on the exhaust nut, the screw thread (6) that cooperatively interacts is arranged on pressure limiting valve and the air nozzle.
