Abstract

The utility model is characterized in that an exhaust pipe is added on a cooker cover of an ordinary pressure cooker. A pressure limiting valve is fastened on the cooker cover. Thus, when one exhaust pipe is blocked by food in the cooker, other exhaust pipes can still be used for exhaust. The explosion accident of the pressure cooker can be completely avoided. The worry of the explosion of the pressure cooker for extensive users can be relieved. The utility model which can be easily accepted by the extensive users has the advantages of simple structure and convenient utilization. The new product emergently required by markets can be produced by a manufacturer producing traditional pressure cookers without the requirements of technical innovation and reequipment. The utility model can be easily accepted by pressure cooker manufacturers for mass production input.

Description

Many pressure limiting valves safe pressure cooker

The utility model belongs to daily living article.

The existing pressure cooker in market generally only is equipped with a blast pipe, a pressure limiting valve and a meltable sheet style safety valve.When the pressure cooker improper use, blast pipe is blocked, the functional failure of meltable sheet style safety valve, gas pressure constantly increases in the pot, so that the maximum gas pressure that the air pressure breakthrough pressure pot in the pressure cooker can bear and blasting, cause personal injury and property loss, users urgently wish to address this problem.

The purpose of this utility model is in order to address the above problem, to propose many pressure limiting valves safe pressure cooker a kind of simple in structure, safe and reliable.

The purpose of this utility model is achieved in that

On the pot cover of pressure cooker, increase some blast pipes, and buckle pressure limiting valve, like this when a blast pipe by pot in food when stopping up, but the still exhaust of remaining blast pipe, pressure cooker just can not explode.

Below in conjunction with embodiment shown in the drawings the utility model is further described.

Fig. 1 is many pressure limiting valves safe pressure cooker profile, and is as shown in the drawing, and this pressure cooker is the pot of two pressure limiting valve safe pressures, and its excess-three structure individual or three above pressure limiting valve safe pressure cookers is similar with it, only sets up blast pipe and pressure limiting valve more, so no longer repeat.Clear in order to illustrate, this figure has omitted hatching.

As shown in Figure 1, (1) and (1 ') is blast pipe, connect firmly by nut and pot cover (4), its central through hole with the pot in communicate, withhold (2) and (2 ') pressure limiting valve on it respectively; (3) be meltable sheet style safety valve, be located on the pot cover (4); (5) be sealing rubber ring of pressure cooker; Upper handle (6) connects firmly with pot cover (4); Lower handle (7) connects firmly with pot body (8); Auxiliary-handle (9) connects firmly with pot body (8), and relative with the position of lower handle (7).Fig. 2 is the vertical view of three pressure limiting valve safe pressure cookers.(2) and (2 ') be pressure limiting valve.

The using method and the usual pressure pot of this many pressure limiting valves safe pressure cooker are basic identical, only need to buckle corresponding pressure limiting valve more.

These many pressure limiting valve safety pressure cookers have following remarkable advantage: it is simple in structure, Cost increases few, but its security performance improves greatly, can remove users and work as The worry of heart pressure cooker blast. Each pressure limiting valve can arbitrarily be withheld on each blast pipe, Do not have strict order and check mark requirement, can adapt to users' use habit, Simple to operate, easily accept for users. Existing traditional pressure cooker manufacturer, Change production many pressure limitings of the present utility model at original traditional pressure cooker production line The new product of valve safe pressure cooker, need not to update the equipment increases investment, only needs With the punching position of the punching die on the pot cover and quantity change just can, can avoid The investment risk of technological transformation can be produced again the new product that the user welcomes, and has Good economic benefit and social benefit are so easily accept for pressure cooker manufacturer.

Claims

1, a kind of many pressure limiting valves safe pressure cooker of being made up of pot cover, pot body, last lower handle, rubber seal, blast pipe, pressure limiting valve etc. is characterized in that being equipped with on the pot cover two or more blast pipes, withholds pressure limiting valve on this blast pipe.
