Abstract
The present invention relates to the pressure cooker of daily living article, the pot and sealing ring of a kind of pressure cooker are mainly by pot, sealing ring, press strip forms, the pot cover of the press strip and pressure cooker connects as one, the outer rim arc in its cross section matches with the sealing ring, there is groove in one week along face in the pot, the sealing ring is located in the groove, by upper branch arc and lower branch arc, symmetrically connection forms the sealing ring back-to-back, the height of the press strip can discharge the air of the lower branch arc and so that negative pressure is formed between the sealing ring and the groove floor tightly adsorbs sealing.The present invention designs according to principle of negative pressure, the good sealing effect of its sealing ring, and simple structure cost is low, is not easy the service life length that fails；Condensate in the groove may not flow into the pot, safety and sanitation.
Description
Technical field
The present invention relates to the pressure cooker of daily living article, easily failed leakage especially for the sealing ring of existing pressure cooker
Gas and design, the condensate on sealing ring will not flow directly into pot among food using it is more hygienic, sealing effectiveness is preferable
The pot and sealing ring of a kind of pressure cooker.
Background technology
Thickness diminishes and causes failure, it is necessary to often change after existing high-pressure cooker sealing ring aging；Especially for electronics
The timer reservation type pressure cooker of control, people are also sleeping soundly when pressure cooker works, and wait morning and get up finding high pressure when setting a table
Pot has been burnt out, and this is due to caused by sealing ring gas leakage causes pressure cooker dry combustion method, though therefore sealing ring is gadget energy
Maintain operating pressure in pressure cooker；It is exactly that the condensate on sealing ring is flowed directly into pot that existing sealing ring, which also has a defect,
In food so that there is rubber taste, hence it is evident that unhygienic in food.Many methods are employed in order to solve these problems people, it is existing
Have that patent is a lot, but it is most of excessively complicated.In fact as conventional cooker, its sealing problem should have one forever to pressure cooker
The solution of property, to settle the worry of every household, the pot and sealing ring of a kind of pressure cooker can solve this problem.
The content of the invention
In order to solve the above problems, the pot and sealing ring of a kind of pressure cooker are designed according to principle of negative pressure, profit
There will not be the principle of gas exchanges with the external world with a confined space, make effect of the sealing ring in pressure cooker more effective；Also have
There is a groove that a circle specially deposits sealing ring, the condensate storage on sealing ring in a groove, will not be flowed directly into pot.
Scheme of the present invention is：
The pot and sealing ring of a kind of pressure cooker are mainly made up of pot, sealing ring, press strip, the press strip and high pressure
The pot cover of pot connects as one, the outer rim arc in its cross section matches with the sealing ring, along face one week in the pot
With groove, the sealing ring is located in the groove, and the sealing ring is by upper branch arc and lower branch arc symmetrical connection group back-to-back
Into the air of the lower branch arc can be discharged and cause shape between the sealing ring and the groove floor by the height of the press strip
Sealing is tightly adsorbed into negative pressure, it is desirable to which the groove floor finish is good.
Branch arc is rubd or a whole big sucker of annular equivalent to numerous continuous skin under the sealing ring, when the press strip
When compressing branch arc on the sealing ring, the air of branch arc is discharged and forms negative pressure between the groove floor under the sealing ring
Even vacuum, plays closed effect.Pressure piece is the pot, the groove, the sealing ring, the press strip and pot cover.Institute
State the storage of the condensate on sealing ring to may not flow into a groove in the pot, a small amount of water in the groove can also increase close
Close effect.The sealing ring can be with two-sided use.
The beneficial effects of the invention are as follows：
The pot and sealing ring of a kind of pressure cooker design according to principle of negative pressure, the good sealing effect of its sealing ring, structure
Make simple cost is low, be not easy fail service life length；Condensate in the groove may not flow into the pot, defend safely
It is raw.
Brief description of the drawings
Further illustrated with reference to the figure of the present invention：
Fig. 1 is one of schematic cross-sectional view of the press strip, sealing ring, groove；
Fig. 2 is the cross-sectional profile enlarged schematic partial view of the sealing ring；
Fig. 3 be the press strip, sealing ring, groove schematic cross-sectional view two.
In figure, 1. pots, 2. press strips, 3. sealing rings, 4. grooves.
Embodiment
If Fig. 1 is one of schematic cross-sectional view of the press strip, sealing ring, groove, reflect that the press strip is not depressed into institute
State position relationship during branch arc on sealing ring；
If Fig. 2 is the cross-sectional profile enlarged schematic partial view of the sealing ring；
The pot and sealing ring of a kind of pressure cooker are mainly made up of pot, sealing ring, press strip, the press strip (2) with
The pot cover of pressure cooker connects as one, the outer rim arc in its cross section matches with the sealing ring (3), the pot (1)
On along face there is groove (4) in one week, the sealing ring (3) is located in the groove (4), the sealing ring (3) by upper branch arc and
Symmetrically the air of the lower branch arc can be discharged and caused described lower branch arc by connection composition, the height of the press strip (2) back-to-back
Negative pressure is formed between sealing ring (3) and the groove (4) bottom surface and tightly adsorbs sealing.
As Fig. 3 be the press strip, sealing ring, groove schematic cross-sectional view two, reflect that the press strip pushes i.e. high pressure
Pot cover cover after position relationship, the press strip compresses branch arc on the sealing ring, at this moment under the sealing ring branch arc sky
Gas is discharged and negative pressure even vacuum is formed between the groove (4) bottom surface so that the sealing ring is in normal sealing state.
Embodiment one, when the pot and sealing ring of a kind of pressure cooker are used in ordinary high pressure pot, the pot is institute
State the pot of ordinary high pressure pot.
Embodiment two, when the pot and sealing ring of a kind of pressure cooker are used in electric pressure cooker, the pot is described
The interior pot of electric pressure cooker.
Embodiment three, two arcs of the sealing ring should include the various curves that can form sucker effect, such as " U " word,
" V " word, parabola, ellipse, circular curve etc..
In use, pressure cooker lid is covered and rotated after an angle buckles well, the press strip (2) compresses the sealing ring
(3) upper branch arc, the air of branch arc is discharged and tightly holds the groove (4) bottom surface under the sealing ring (3)；It is simultaneously described close
The upper branch arc of seal (3) can wrap the press strip (2) after being pressurized, it is described under gas pressure in pot on also can be tightly on the inside of branch arc
The press strip (2) is touched, therefore obturation effect is especially good.Condensate in the groove is cleared up in the lump when cleaning pot, and
The groove floor finish is kept, in case next normal use；After completion pressure cooker lid of cooking is opened, the sealing ring
(3) if under branch arc be just not necessarily to hard draw when still tightly holding the groove (4) bottom surface and get off, next normal use.
