Abstract
The utility model discloses a pressure cooker with three safe, relating to pressure cookers and belonging to safe air lockers which are acted and opened under certain pressure range in pressure vessels, and the pressure cooker with three safe is suitable for pressure cookers of civil cooking utensils. The pressure cooker with three safe is characterized in that the two-thirds position of the cooker body is provided with one or more than one emergency vents whose outer sides are provided with a slope, and the metal top plate is provided with a special convex rubber plug; the rubber plug slides towards the air vent along the slope and the air vent is plugged. The utility model has the advantages of simple structure, easy processing and manufacture, low cost, reliable performance, etc. When used, the safe performance of the pressure cooker is very high to people who can not use the pressure cooker particularly.
Description
The utility model relates to pressure cooker, belongs to the safe vent plug that effect is opened in the certain pressure scope in the pressure vessel, is applicable to a kind of three proof pressure pots in the civilian kitchenware pressure cooker.
Commercially available double safety pressure cooker mainly contains two kinds at present: a kind of is rubber ring type, owing to be subjected to the influence of elastic rubber, frictional force, and extremely unreliable in the use; Another kind is a helical spring type, promptly working above under the former pressure limiting valve operating pressure, and complex structure, requirement on machining accuracy height, cost height.
The purpose of this utility model is exactly in order to overcome above-mentioned the deficiencies in the prior art part, and a kind of dependable performance is provided, and simple in structure, processing and fabricating is easy, the three proof pressure pots that cost is low.
The purpose of this utility model is achieved in that a kind of pressure cooker of being made up of pot body, pot cover, has one or more urgent steam vents at pot body place, and there is a slope in the outside of urgent steam vent; The metal top plate upper end is connected with the pot cover outside, and the metal top plate lower end is provided with a shrinkage pool, and special convex rubber stopper is housed on the shrinkage pool.Urgent steam vent is provided in a side of 2/3 above position of pot body, the slope in the urgent steam vent outside, and direction is identical with the pot cover direction of rotation, i.e. clockwise direction; Urgent steam vent and the molding drawing together of pot body; Metal top plate is with pot cover molding drawing.
Below in conjunction with accompanying drawing, the utility model will be further described:
Fig. 1 is the utility model overall structure schematic diagram;
Fig. 2 is the utility model A-A structural representation;
Fig. 3 is the utility model partial structurtes schematic diagrames.
Shown in Fig. 1～3, (1) pot cover, (2) pot body, (3) urgent steam vent, (4) metal top plate upper end, (5) metal top plate lower end, (6) shrinkage pool, (7) rubber stopper, (8) slope.A kind of by pot body (2), the pressure cooker that pot cover (1) is formed, locate to have one or more urgent steam vent (3) at pot body (2), the outside of urgent steam vent (3), a slope (8) is arranged, metal top plate upper end (4) is connected with pot cover (1) outside, metal top plate lower end (5) is provided with a shrinkage pool (6), special convex rubber stopper (7) is housed on the shrinkage pool (6), urgent steam vent (3) is provided in a side of 2/3 above position of a pot body (2), the slope (8) in urgent steam vent (3) outside, direction is identical with pot cover (1) direction of rotation, i.e. clockwise direction; Urgent steam vent (3) is with the molding drawing of pot body (2), metal top plate (4,5) pot covers (1) molding drawing together.During use, cover pot cover, special convex rubber stopper is slided along the slope and is upward clogged urgent steam vent, and the top plug has sealed the urgent steam vent of pot body tightly; When the user opens pot cover, twist pot cover, the metal top plate on the pot cover moves along the slope along with the rotation of pot cover, removes in urgent steam vent, has so just opened urgent steam vent, and the high-pressure hot gas in the pot just sprays from steam vent rapidly.
The utility model has following advantage compared to existing technology: simple in structure, processing and fabricating is easy, and cost is low, dependable performance, and particularly to people that can not the working pressure pot, during use, security performance is high.
