CN2248511Y - Pressure-cooker with safety cover for open and close - Google Patents

Abstract

The utility model relates to a pressure cooker with a safety opening and closing cover, which is mainly composed of a side handle, a cooker cover, a safety exhaust valve, a cooker body, a pressure regulating valve, an upper handle component and a lower handle, wherein a cover opening and closing device is arranged in the upper handle component; a floating valve is arranged on the cooker cover and is positioned in front of a support board on the cover opening and closing device; the front end of the support board is a flat and straight surface which is vertical to a valve core of the floating valve. The cooker cover of the utility model can not be opened under the condition that the utility model has pressure. The cooker cover can be opened only when the pressure in the utility model disappears. Furthermore, when the cooker cover and the cooker body are not closed in place, high pressure gas can not be generated in the utility model. Therefore, the safety of users is absolutely ensured.

Description

Safe opening and closing lid pressure cooker

The utility model relates to a kind of pressure cooker, the pressure cooker of especially safe opening and closing lid.

Chinese patent 95240247.5 discloses the compound bottom pressure pot of a kind of stainless steel, this pot is provided with the opening and closing lid arrangement in the up knob assembly, opening-closing cover device by cam, make torsion spring that cam resets, support plate, push button, and " Jiong " type spring that connects support plate and cam form, cam is connected with up knob by camshaft, establish a kidney slot in the middle of the support plate, cam is connected together support plate and up knob by this kidney slot, the age of a draught animal is established in the position corresponding with cam on the pot body, after pot cover covered, cam promptly embedded in the age of a draught animal.Push button is fixedlyed connected with support plate on the up knob.The promotion push button travels forward, and " Jiong " type spring is that actuating cam rotates, and leaves the age of a draught animal on pot body, thereby opens pot cover.When opening pot cover, support plate travels forward, and a front edge of board inclined-plane compressing is positioned at the float trap spool on the pot cover, emission gases.Therefore, when pot cover was opened, the gases at high pressure that remain were rushed out, and easily human body are damaged.

The purpose of this utility model is exactly at above-mentioned defective, designs a kind of pressure cooker of safe opening and closing lid, when in pot, gases at high pressure being arranged, pot cover can not the people for opening, thereby assurance user's safety.

The purpose of this utility model is achieved through the following technical solutions:

The utility model is made up of side grip, pot cover, safety exhaust, pot body, pressure-regulating valve, up knob assembly, following handle, establish the opening and closing lid arrangement in the up knob assembly, establish a float trap on the pot cover, and be positioned at the support plate the place ahead on the opening and closing lid arrangement, front edge of board is a flat face and perpendicular to the float trap spool.

Float trap is made up of valve body and spool, and valve body is made up of upper and lower nut and sealing gasket, and connects with pot cover by upper and lower nut, and the spool sky is enclosed within the valve body.

Spool both sides fluting, bottom are taper and middle fluting, and when spool dropped on the valve body bottom, gas was discharged by spool two side channels.In case in the pot gases at high pressure are arranged, spool promptly lifts, and float trap is shut.

Technical characterstic of the present utility model and result of use:

1, compare with the compound bottom pressure pot of Chinese patent 95240247.5 stainless steels, change original air bleeding valve into float trap, invariant position, former front edge of board inclined-plane changes flat face into.

2, when in the pot gases at high pressure being arranged, the float trap spool lifts, at this moment, desire to open pot cover, promote the key on the opening and closing lid arrangement, because of a front edge of board withstands on the spool, can not move on, the opening and closing lid arrangement is failure to actuate, and pot cover is not opened, so can not damage to human body, have only the air bleeding valve of working as that high pressure gas is all drained, the float trap spool just falls, and promote key this moment, support plate advances, the action of opening and closing lid arrangement, pot cover is opened.

3, close when not in place when pot cover, a pot body, support plate is pressed on the spool, and along with the increase of pot internal gas pressure, spool can not lift, and gas is discharged by spool two side channels, thereby guarantees user's safety.

Below in conjunction with accompanying drawing the utility model is done further narration:

Accompanying drawing 1 is a structural representation of the present utility model.

1 is side grip, the 2nd among the figure, pot cover, the 3rd, air bleeding valve, the 4th, pot body, the 5th, pressure-regulating valve, the 6th, float trap, the 7th, up knob assembly, the 8th, following handle.

Accompanying drawing 2 is safe opening and closing lid arrangement structural representations.

9 is pot bodies, the 10th among the figure, pot cover, the 11st, following nut, the 12nd, sealing ring, the 13rd, spool, the 14th, upper cap nut, the 15th, support plate, the 16th, up knob, the 17th, rubber blanket, the 18th, sealing ring, the 19th, torsion spring, the 20th, camshaft, the 21st, cam, the 22nd, Jiong shape spring, the 23rd, push button.

Float trap is made up of upper cap nut 14, following nut 11, sealing ring 12, spool 13 as shown in the figure, is positioned at the place ahead of support plate 15, and support plate 15 front ends are flat face, and vertical spool 13.

Claims (3)

1, a kind of safety opening-closing cover pressure cooker, mainly form by side grip, pot cover, safety exhaust, pot body, pressure-regulating valve, up knob assembly, following handle, establish the opening and closing lid arrangement in the up knob assembly, it is characterized in that establishing on the pot cover float trap, and be positioned at the support plate the place ahead on the opening and closing lid arrangement, front edge of board is a flat face and perpendicular to the float trap spool.

2, the safe opening and closing lid pressure cooker of narrating according to claim 1 is characterized in that float trap is made up of valve body and spool, and valve body is made up of upper and lower nut and sealing gasket, and passes through upper and lower nut and connect with pot cover, and the spool sky is enclosed within the valve body.
