Abstract
The utility model belongs to an assisted safety using device of pressure cooker, which includes a valve seat which is installed on the pressure cooker and has a transfixion hole; an anti-opening valve stem which is penetrated on the transfixion hole and can slide up and down, the anti-opening valve stem is also provided with a display head which can extend out of the upper handle; a seal ring and a seal gasket which are respectively embedded at the middle and the lower of the anti-opening valve stem. When the cooker has a certain pressure, the anti-opening valve stem moves up, and the display head thereon extends out of the upper handle, which indicates the cooker has pressured, people can not open the cooker cover, so that the utility model can reach the purpose of safe using. The utility model has the advantages of simple structure, convenient and safe using, long service life and others, which can replace the anti-opening valve in the open/close cover safety mechanism.
Description
The utility model belongs to pressure cooker auxiliary security operative installations, and particularly the pressure that is used with the pressure cooker open and close cover release mechanism shows valve.
For fear of cause contingency because of the pressure cooker lid folding is improper, the applicant had once applied for May 28 nineteen ninety and on October 29th, 1999 that the patent No. was respectively two kinds of pressure cooker open and close cover safeties patents of 98214955.7 and 992515831.They are provided with a self-locking mechanism on the usual pressure pot handle, when pot cover covers when not in place, pot inner pressure can not raise, and when in the pot pressure being arranged, pot cover can not be opened, thereby has guaranteed the pressure cooker open and close process safe.But do not show the pot inner pressure state in such safeties, this makes troubles to the user, and violation operation takes place easily, causes parts damages, influences the service life and the service behaviour of folding lid safeties.For this reason, the applicant has applied for that on September 4th, 2000 patent No. is 00251332.3, name is called the utility model patent of " pressure cooker pressure-display device ", and it has solved the problems referred to above preferably, but this patent and original stopping valve are used in combination complex structure, many, easy to failure, the damage of parts in addition.
The purpose of the utility model is to provide the stopping valve in a kind of and the pressure cooker open and close cover insurance institution to form one, can show that the safety of pot inner pressure shows valve.Its technical scheme is such: it comprises and is contained in the valve seat that has through hole on the pressure cooker, be applied in the stopping valve bar that on the through hole, also can slide up and down, have the bubble head that can stretch out upper handle on the stopping valve bar, stopping valve bar middle part and lower end are embedded with the sealing ring and the sealing gasket of energy seal valve seat through hole respectively.Operation principle of the present utility model is such: when in the pot pressure being arranged, move on the stopping valve bar, be pressed on the valve seat through hole until the sealing gasket envelope, at this moment, the bubble head of stopping valve masthead end stretches out upper handle, in the expression pot pressure is arranged.As long as in the pot certain air pressure is arranged, the stopping valve bar just can stop pot cover to be opened by folding lid safeties, thereby reaches the purpose of safe handling pressure cooker.Owing to directly have bubble head on the stopping valve bar in the folding lid safeties, and the stopping valve bar rises and when dropping to desired location, seal is arranged all; So it has advantages such as simple in structure, easy to use, safe, good airproof performance, long service life, can replace the stopping valve in the folding lid release mechanism.
In order more observably to remind user's safety operation, the utility model is being coated color on bubble head.
Below in conjunction with embodiment shown in the drawings, the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation that the utility model and folding box safeties are used.
Referring to Fig. 1, Fig. 2, pressure cooker safety shows valve by the valve seat 4 that has through hole 3, is applied in the stopping valve bar 1 that can move up and down on the through hole 3 and is embedded in stopping valve bar 1 sealing ring 5 and sealing gasket 2 middle and lower end sealing through hole 3 to form.Valve seat 4 usefulness nuts 6, O-ring seals are fixed on pot cover 8 and are positioned on the folding lid release mechanism; The stopping valve core of stopping valve bar 1 double as folding lid release mechanism, its upper end scribbles the bubble head 7 of color sign, when in the pot pressure being arranged, steam jack-up stopping valve bar 1 in the pot makes bubble head 7 stretch out pressure cooker upper handle 9, at this moment, in the expression pot pressure is arranged, the user can not open pot cover 8.When not having pressure or pressure very little in the pot, stopping valve 1 drops to nature under the effect of gravity, and folding lid release mechanism is opened, and pot cover can be opened.
