Abstract
The utility model relates to a sealing structure for an exhaust pipe and a pressure limiting valve of a pressure cooker. The sealing structure comprises a cover, wherein the exhaust pipe is fixed on the cover and is provided with the pressure limiting valve consisting of a valve cap, a valve body and a valve core; the valve core is hermetically matched with an exhaust pipe hole on the top end of the exhaust pipe; and the valve core is made of a silica gel material or the silica gel structure is arranged at the exhaust pipe hole. The sealing structure has the beneficial effects of good sealing property, no steam leakage during cooking, higher safety for user, better cooking effect due to no steam leakage, capabilities of reducing accuracy requirements of machining of the exhaust pipe hole and the valve core and improving the sealing property and lower cost of the silica gel valve core than a metal valve core.
Description
Technical field
The utility model relates to a kind of household kitchen electric appliance technical field, the hermetically-sealed construction of especially a kind of pressure cooker blast pipe and pressure limiting valve.
Background technology
At present, the pressure limiting valve of known naked light pressure cooker or electric pressure cooker and inner spool all are to adopt stainless steel or copper material; Blast pipe also all is to adopt metal materials such as aluminium alloy, stainless steel to process; The sealing of this traditional spool and the metal between the blast pipe to the hole of blast pipe with spool face is coarse, the requirement on machining accuracy of concentricity is high, and finally can not be accomplished to seal fully; Give the unsafe sensation of consumer, influence the effect of cooking food simultaneously.
Summary of the invention
The utility model will solve the shortcoming of above-mentioned prior art, and a kind of pressure cooker blast pipe of good airproof performance and the hermetically-sealed construction of pressure limiting valve are provided.
The utility model solves the technical scheme that its technical problem adopts: the hermetically-sealed construction of this pressure cooker blast pipe and pressure limiting valve; Comprise pot cover; Be fixed with blast pipe on the pot cover; Blast pipe is provided with the pressure limiting valve of being made up of bonnet, valve body and spool, and the exhaust duct aperture on spool and blast pipe top forms and is sealed and matched, and spool is that silica gel material or exhaust duct aperture place are provided with silica gel structure.
As preferably, said exhaust duct aperture is the notch cuttype circular hole, and the diameter of upper end is greater than the lower end, and its upper end is provided with silicone-rubber seals.
As preferably, said spool is located on bonnet or the valve body.
The effect that the utility model is useful is: one, good airproof performance, and no steam spills in the cooking process, gives the safer sensation of user; Two, owing to no steam leakage, the culinary art better effects if of food; Three, reduced required precision, improved sealing property the processing of exhaust duct aperture and spool; Four, the silica gel spool is lower than the cost of metal spool.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further:
Embodiment 1: like Fig. 1, the hermetically-sealed construction of this pressure cooker blast pipe and pressure limiting valve comprises pot cover 7; Be fixed with blast pipe 4 on the pot cover 7, blast pipe 4 is provided with the pressure limiting valve of being made up of bonnet 1, valve body 2 and spool 3, and wherein exhaust duct aperture 6 is the notch cuttype circular hole; The diameter of upper end is greater than the lower end; Its upper end is inlayed the silicone-rubber seals 5 that has through hole, and when pressure limiting valve is installed on the blast pipe 4, valve body 2 drops on the blast pipe 4 according to deadweight; The spool 3 of metal inserts and is embedded in silicone-rubber seals 5 holes on the blast pipe 4, promptly realizes sealing fully.
Embodiment 2: like Fig. 3, plant the hermetically-sealed construction of pressure cooker blast pipe and pressure limiting valve, comprise pot cover 7; Be fixed with blast pipe 4 on the pot cover 7, blast pipe 4 is provided with the pressure limiting valve of being made up of bonnet 1, valve body 2 and spool 3, and wherein spool 3 used materials are silica gel; Be located on valve body 2 or the bonnet 1, when pressure limiting valve is installed on the blast pipe 4, valve body 2 drops on the blast pipe 4 according to deadweight; Silica gel spool 3 inserts in the exhaust duct aperture 6, promptly realizes sealing fully.
The above pressure limiting valve comprises but is not limited to heavy bell type pressure limiting valve and spring valve.
Except that the foregoing description, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
