Pressure in the safety anti-explosion pressure cooker can not rise when the upper handle and the lower handle are not fastened in place. When the pressure in the pressure cooker is more than 5KPa, the cooker lid can not be opened. When the pressure in the pressure cooker rises up to 220 (+/-) 20KPa, decompression safety with a high flow rate can be realized, which can ensure the pressure cooker not to explode.

Description

The safe anti-explosion pressure cooker

The utility model relates to a kind of domestic cookers, especially a kind of pressure cooker.

Along with improving constantly of people's living standard, people's security needs consciousness is more and more strong, pressure cooker is as a kind of modern mess kit, though it has advantages such as time-saving energy-saving, but the quick-fried pot incident of hurting sb.'s feelings takes place repeatedly, so far do not have yet on the market and can really realize many insurances, the particularly pressure cooker of explosion prevention function sale.

The purpose of this utility model is to overcome the defective of existing pressure cooker explosion-proof security difference, and when providing a kind of pot cover to build, pot inner pressure can not rise; And when pot inner pressure when 5kpa is above, pot cover can't be opened; Malfunctioning when pressure limiting valve and safety valve, pot inner pressure raises when reaching 220 ± 20kpa, can realize big flow pressure release insurance, guarantees the explosion-proof safety pressure cooker that pressure cooker can quick-fried pot.

Task of the present utility model realizes in the following manner: this pacifies golden explosion-proof type pressure cooker, comprise a pot body, pot cover, pressure limiting valve, upper handle and lower handle, pot cover is provided with I shape silica gel explosion-proof plug, silica gel explosion-proof plug central authorities are provided with valve rod, be processed with vapor opening on the valve rod, be provided with the safety valve valve body near the upper handle place on the pot cover, be provided with spool in the valve body, compression spring and rubber cushion, be provided with slide block and rear slider between upper handle and the lower handle, be fixed with push pedal by screw on the front-slider, be fixed with push pedal by screw on the rear slider, be provided with stage clip between front-slider and the rear slider.

The utility model is worked as upper handle and is not overlapped with lower handle, and promptly pot cover does not fasten when putting in place, and pot inner pressure can not rise, and can guarantee to close the security of lid; When pressure (greater than 5kpa) was arranged in the pot, pot cover can't be opened, and can guarantee the security of uncapping, and can not hindered by hot cold perm in the pot because of uncapping by force; When pressure limiting valve and safety valve were malfunctioning, when pot inner pressure was increased to 220 ± 20kpa, the valve rod in the explosion-proof plug by the vapor opening pressure release, can be guaranteed that pressure cooker can quick-fried pot by pot internal gas pressure upper punch.

The utility model meets base fully to being higher than the GB13623-92 standard that pressure cooker is produced, and is simple in structure, uses reliably, and cost is low, good manufacturability, can about close lid.

Concrete structure of the present utility model is provided by drawings and Examples.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the vertical view of lower handle 19 among Fig. 1.

Below in conjunction with drawings and Examples the utility model is described in more detail.

Embodiment:

With reference to Fig. 1, Fig. 2, this safe anti-explosion pressure cooker is by pot body 1, pot cover 2, pressure limiting valve 6, upper handle 16 and lower handle 19 are formed, I shape silica gel explosion-proof plug 3 is housed on the pot cover 2, silica gel explosion-proof plug 3 central authorities are provided with valve rod 4, be processed with vapor opening 5 on the valve rod 4, be provided with safety valve valve body 8 near upper handle 16 places on the pot cover 2, be provided with spool 9 in the valve body 8, compression spring 10 and rubber cushion 7, be provided with front-slider 17 and rear slider 15 between upper handle 16 and the lower handle 19, be fixed with down push pedal 12 by screw 13 on the front-slider 17, be fixed with push pedal 11 by screw 14 on the rear slider 15, be provided with stage clip 18 between front-slider 17 and the rear slider 15.

Operation principle of the present utility model is as follows: when the upper handle 16 of pressure cooker and lower handle 19 do not fasten when putting in place, front-slider 17 is push pedal 12 reaches under promoting under the effect of stage clip 18, the front end of following push pedal 12 is pushed down the half-edge hole of spool 9 all the time, make in the pot to communicate, guarantee that pot inner pressure can not rise with the external world.When last lower handle fastens fully, front-slider 17 is by the inclined-plane pusher above the lower handle 19, move after promptly descending push pedal 12 front ends, leaving spool retreats, rear slider 15 is also simultaneously after driving push pedal 11 reaches again under the effect at elastic force under the effect on lower handle inclined-plane, make lower end moment of rear slider 15 snap in self-locking in the square groove of lower handle 19, guaranteed the normal occlusion lid operation of pressure cooker.When the user wants to open pot cover, uncap by force if forgotten to unload pressure limiting valve, spool 9 is by pot internal gas pressure jack-up at this moment, and rear slider 15 pushes away the motionless push pedal 11 of going up, and promptly the square groove 20 on the lower handle 19 can not slided in the lower end of rear slider 15, and pot cover can't be opened.When pot inner pressure reached 220 ± 20kpa, the valve rod 4 in the I shape silica gel explosion-proof plug 3 had been dashed pressure release by pot internal force air pressure, guaranteed that pressure cooker can quick-fried pot.
