Abstract
The utility model relates to an automatic safety device for a cover of a pressure cooker, which is composed of an exhaust hole sleeve, a seal rubber sleeve, a support sleeve, a fixed seat, a safety plug, a seal gasket and seal screws, wherein the safety plug is arranged on the body of the pressure cooker via the support sleeve and the fixed seat; the hollow safety plug has side holes, and the lower end is provided with the seal gasket; the side holes of the lower end are sealed when the safety plug is pushed by gas pressure, and the support sleeve is tightly pressed by the seal gasket. The utility model has the advantages of artful structure, simple structure, good fastness, safe operation and long service life.
Description
The utility model belongs to a kind of pressure cooker open and close cover automatic safety.
At present, the pressure cooker lock uint has of all kinds, as patent 95244228.0 pressure cooker open and close safety controls, patent 95230981.5 pressure cooker safety devices, structure are complicated, and technology is complicated, easy cleaning not, damage easily, practicality is strong inadequately, can not effectively solve when uncapping still surplus more atmospheric phenomenon in the pot, difficulty is installed, use safety inadequately, convenient inadequately, the life-span is short.
The purpose of this utility model is to provide a kind of easy installation, and is safe in utilization, pressure cooker open and close cover automatic safety simple in structure.
The utility model is by the steam discharge borehole jack, seal rubber sleeve, splicing sleeve, holder, safety plug, seal gasket, screw is formed, steam discharge borehole jack (2) is contained on the exhaust hole of pot cover (1), seal rubber sleeve (3) is contained in below the steam discharge borehole jack (2), holder (7) is contained in a pot body (11) splicing sleeve (4) seat in the hole of holder (7), safety plug (8) is placed in the hole of splicing sleeve (4), safety plug (8) has centre bore, the bottom communicates with side opening (a), seal with seal gasket (9) and screw (10) lower end of safety plug (8), when pressure cooker gets togather when covering, safety plug (8) aligns the position of exhaust hole; Air pressure is with on safety plug (8) top time, and (a) is sealed for side opening, and seal gasket (9) compresses splicing sleeve (4).
Described splicing sleeve (4) is placed in the hole of holder (7) by spring rubber cushion (5).Described seal rubber sleeve (3) can not be contained in below the steam discharge borehole jack (2), but left-hand thread is enclosed within splicing sleeve (4) upper end, and can not adorn steam discharge borehole jack (2) on the exhaust hole this moment.Safety plug (8) centre bore can not be axial clear opening, and seal on its top, and (b) communicates with centre bore by side opening.
The utility model is simple in structure, and is very firm, very practical, ordinary people's operation is all very safe, effective, long service life, can reliably prevent to make producer and user all relieved, be worth promoting because misoperation is promptly closed in the not in place and pot of lid band strong phenomenon of uncapping during air pressure.

Fig. 2 looks cutaway view for the utility model left side;
Fig. 3 is another example structure schematic diagram of the utility model;
Schematic diagram when Fig. 4 does not put in place for the utility model closes lid.
As described in Figure 1, this device is made up of pot cover (1), pot body (11), steam discharge borehole jack (2), seal rubber sleeve (3), splicing sleeve (4), spring rubber cushion (5), rivet (6), holder (7), safety plug (8), seal gasket (9), sealed screw (10).Earlier at the good installing hole of pot body (11) upper punch, use rivet (6) (countersunk head, cup head all can) that holder (7) is riveted tightly at the pot marginal position of side on one's body then.Height can be when actual production, and by heightening or lowering steam discharge borehole jack (2), seal rubber sleeve (3), splicing sleeve (4), spring rubber cushion (5), the size of several parts is to reach best fit.Behind the good holder of riveting, splicing sleeve (4) is loaded onto spring rubber cushion (5) put into holder (7), again safety plug (8) is put into splicing sleeve (4), the sealed screw (10) that will have seal gasket (9) then is tightened on the safety plug (8), the part installation in the pot.Part on the pot cover, dash an installing hole at the edge of pot cover earlier, then by stationary fit, or rivet tightly or mode such as screw down loads steam discharge borehole jack (2) on pot cover (1), again seal rubber sleeve (3) expansion after-contraction is locked and puts at exhaust hole, this cover can be contained in above the pot cover, also can be contained in below the pot cover.Total is installation just.Close the lid location and can on pot body tooth, go out a boss, to reach the location purpose.Its operation principle is: after device installs, when Dang Hegai puts in place, because spring rubber cushion (5) and seal rubber sleeve (3) are higher, thereby have elastic force that supporting base (4) and seal rubber sleeve (3) are compressed by compression the time, reach sealing function.When producing steam in the pot by the time, pressure promotes safety plug (8) and rises, enter steam discharge borehole jack (2), seal gasket (9) compresses the splicing sleeve bottom and plays sealing function, just plays safety effect, when in the pot residual air being arranged, lid is not opened, and presses when venting, does not have pressure in the pot, safety plug (8) falls automatically, can uncap safely.Pressure cooker closes lid when not in place, as shown in Figure 4, safety plug (8) rises under air pressure promotes, sealed gum cover (3) blocks, do not enter steam discharge borehole jack (2), gas is just discharged from the side opening (b) of safety plug (8), outside steam discharge borehole jack (2) is discharged pot, can not enter pressure in the pot, play to close and cover security purpose.If when the He Gai position differed too big far from the location, gas will directly be discharged from the steam discharge borehole jack, to ensure safety.This device shouldn't steam discharge borehole jack (2), and seal rubber sleeve (3) left-hand thread is enclosed within on the splicing sleeve (4).As shown in Figure 3, the through hole of safety plug (8) can change not hole, road into, and adds the brill aperture aside, and operation principle is constant.In addition, seal gasket (9) can be as square, bowl-type, annulated column shape, or other Any shape, spring rubber cushion (5) but plastics spring rubber cushion, metal gasket, metal spring.Also can not want this part, in addition, the inner hole wall of splicing sleeve and the cylindrical of safety plug also can have little straight trough up and down, annular groove and skewed slot freely for guaranteeing it.
