Abstract

The utility model relates to a float-type interlocking safety device for a pressure cooker. A locking push rod mechanism and a safety float valve are arranged in an upper handle (4) of an ordinary pressure cooker, wherein the locking push rod mechanism is formed by connecting a thrust rod (5), a push rod (10), a spring (11) and a positioning ring (12), and the safety float valve is fixedly arranged on a cooker cover (1) and is composed of a float valve seat (2), a column float core (3), a seal ring (6) and nuts (7) which are combined into a whole. The utility model has the functions that the pressure of the pressure cooker can not increase when the cooker cover is not closed properly, and the cooker cover can not be opened when the pressure cooker has pressure. The utility model has the advantages of simple structure and convenient opening and closing and can effectively ensure the safe use of the pressure cooker.

Description

The chain safety device of pressure cooker float-type

The utility model is the chain safety device of a kind of pressure cooker float-type.

Be the security performance and convenient use of improving pressure cooker, China Patent No. is 94206278.7 " pressure cooker use safeties ", it makes pressure cooker when pot cover does not get togather having increased a self-locking mechanism between the lower handle on the general pressure cooker, and pot inner pressure can not raise; When in the pot pressure being arranged, pot cover can not be opened.When it can avoid pressure cooker to use, because of operate miss causes the steam human accident of burning.But there are two shortcomings: the one, the very important person has increased user's inconvenience for the push pedal on the driving handle when uncapping.The 2nd, this apparatus structure complexity, to in upper handle, increase parts such as push pedal, safety pole, lower handle requires corresponding stopper slot to cooperate, this undoubtedly factory to install a complete set of handle fully and can dispatch from the factory, just make aspect such as production, packing, transportation, storage expense to increase, increased consumer's burden.

The purpose of this utility model provides a kind of handled easily person use habit, can guarantee pressure cooker open and close safety again, the chain safety device of pressure cooker float-type simple in structure.

Realize the utility model scheme be in upper handle, be provided with one by throw-out lever, push rod, spring etc. be connected into locking transfer bar mechanism and rivet clasp on pot cover by the float valve seat, the garden post floats on the safe float-controlled valve that core, sealing ring, nut are formed one.When pot cover and a pot body when not closing fully, throw-out lever can effectively stop garden post plunger core to rise, and sealing ring can not pressed float valve cup bottom plane, and is in exhaust condition, and pot inner pressure is not risen.In normal operation, garden post plunger core is by steam pressure jack-up in the pot, and plays the self-locking effect by hole, garden on throw-out lever and the upper handle, can not uncap.When the whole dischargings of steam in the pot finished, normally folding of pot cover was fallen in post plunger core deadweight in garden.

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

Structural representation when Fig. 1 is the chain safety device operate as normal of pressure cooker float-type;

Fig. 2 is not structural representation during operate as normal of the chain safety device of pressure cooker float-type;

Fig. 3 is a structural representation after the complete exhaust of the chain safety device of pressure cooker float-type;

Fig. 4 is that the half sectional view of float valve seat and A are to view.

Among the figure; 1. pot cover, 2. float valve seat, 3. garden post plunger core, 4. upper handle, 5. throw-out lever, 6. sealing ring, 7. nut, 8. cushion rubber, 9. pot body, 10. push rod, 11. springs, 12. locating rings.

Shown in Figure 1, the chain safety device of pressure cooker float-type is made up of pot cover 1, upper handle 4, cushion rubber 8, a pot body 9, it is characterized in that being provided with throw-out lever 5, push rod 10, spring 11, locating ring 12 and be connected into and lock transfer bar mechanism and rivet clasp form the safe float-controlled valve of one by float valve seat 2, garden post plunger core 3, sealing ring 6, nut 7 on pot cover 1 in upper handle 4.On upper handle 4 and " " type throw-out lever 5 upper ends be respectively equipped with the hole, garden that cooperates with garden post plunger core 3 opposite positions and its top outside dimension, throw-out lever 5 lower ends are provided with the through hole slippery with push rod 10; The big end of push rod 10 is relative with pot body 9 teeth, and small end overlaps upper spring 11 after by throw-out lever 5 through holes and locating ring 12 is fixed in the upper handle 4.Spring 11 is compression springs, and its active force makes throw-out lever 5 can do the certain level displacement.Locating ring 12 effects can not fallen down after the locking transfer bar mechanism is uncapped.Upper handle 4 is packed on the pot cover 1.

Float valve seat 2 rivet clasps that safe float-controlled valve is provided with air slot by endoporus on pot cover 1, the sliding garden post plunger core 3 that is contained in the float valve seat 2, its lower end is equipped with sealing ring 6 and is formed one with nut 7.

Shown in Figure 4, float valve seat 2 endoporus are provided with 4 diagonal angle distribution air slots and make gas channel.

During normal operating conditions, garden post plunger core 3 is by steam pressure jack-up in the pot, and sealing ring 6 is close to float valve seat 2 baseplanes and is sealed, and plays the self-locking effect by hole, garden on throw-out lever 5 and the upper handle 4.

Shown in Figure 2: when pot cover 1 does not close fully with pot body 9 (tooth of pot cover and pot body is not fully to good), push rod 10 big rectifying facing to the teeth on the pot body 9, and move after driving throw-out lever 5, prevention garden post plunger core 3 rises, sealing ring 6 does not have pressed float valve seat 2 baseplanes not seal, and be in exhaust condition, pot inner pressure can not be raise.

Shown in Figure 3, in pot steam all discharging finish, post plunger core 3 deadweights in garden are fallen, throw-out lever 5 activities are freely the time, normally folding use of pot cover.

The chain safety device of this pressure cooker float-type has simple in structure, and folding with convenience can guarantee effectively that pressure cooker is safe in utilization.
