Description
Technical field
The utility model relates to and is used for the container that food steams, boils, particularly a kind of pressure cooker with safety anti-explosive performance.
Background technology
As everyone knows, pressure cooker is to use the principle that the boiling point of air pressure and water is directly proportional, that is to say at the boiling point of the low local water of air pressure also low, otherwise if add atmospheric pressure, the corresponding rising of the boiling point of water.So just help abundant heat food, and kill the various bacteria in the food easily under the high temperature, it is healthy to help people.
As Chinese utility model patent specification (Granted publication number: CN2205689Y) disclose a kind ofly be used for cooking, the back pressure type pressure cooker of Baoshang, on the pot body, have oval port, external circle one end of pot is equipped with back handle, the other end is connected with main handle, and it is made of handle set, handle, gusset piece, key seat, movable key seat.In the pot cover outer rim oval female cap greater than pot body upper port is arranged, its outer rim is equipped with sealing ring, is connected with stop, thick stick bar on the pot cover, and thick stick bar middle part is connected with alignment pin, and afterbody is a upper handle, and clamp is arranged in it.During use, oval female cap rotation is tilted to put into a pot body port, the alignment pin at thick stick bar middle part is stuck in the key seat pit, and clamp is hooked in the hook of gusset piece, and sealant just can not leak-off steam.
This shows that existing pressure cooker all is structures of adopting positive confinement to guarantee that it steams, boils in the process not leak pressure at food.But, steaming, boil in the process in the food heating, the steam that produces in the pot can further increase the pressure in the pot, so, will make pressure excessive, causes the danger of blast.
The utility model content
The purpose of this utility model is to provide a kind of pressure cooker with safety anti-explosive performance, mainly solves the structure that existing pressure cooker adopts positive confinement, so that make service pressure increase the technical problem that is easy to generate blast, guarantees safe in utilization.
For addressing the above problem, the utility model is achieved in that
A kind of safety anti-explosive pressure cooker, it comprises the pot body that is connected with pot cover, it is characterized in that: be embedded with a safe purge valve on this pot body; This safe purge valve comprises a valve body, and this valve body has hollow cavity, is communicated with in the upper end closed of valve body, lower end and the pot body and the lower ending opening place is provided with the retaining edge, has pressure releasing hole on valve body one sidewall; One spool is arranged in the hollow cavity of valve body, and the height of spool is less than the height of valve body hollow cavity, and spool also has hollow cavity, and spool upper end closed, lower end are communicated with the pot body by the valve body lower end opening, also have a pressure releasing hole on the sidewall of this spool; The pressure releasing hole of spool and the pressure releasing hole of valve body are on same axis, and the position of spool pressure releasing hole is lower than the valve body pressure releasing hole; Has a flexible member between the upper surface of this spool upper surface and body cavity.
Described safety anti-explosive pressure cooker is characterized in that: the pressure releasing hole of this valve body is smaller or equal to the pressure releasing hole of spool.
Described safety anti-explosive pressure cooker is characterized in that: this safe purge valve is arranged on the pot cover.
Described safety anti-explosive pressure cooker is characterized in that: have securing member between this pot cover and the pot body.
By technique scheme, the beneficial effects of the utility model are:
Be embedded with a safe purge valve on the pot body of the present utility model, outside the release of the excessive pressure in the pot can being taken the dish out of the pot by this safe purge valve, avoid because the excessive generation explosion phenomenon of pressure.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of safe purge valve in the utility model.
Fig. 3 is the user mode structure chart of safe purge valve in the utility model.
Among the figure:
1-pot body;
The 2-pot cover;
3-safety purge valve;
The 31-valve body;
311-keeps off edge;
The 312-pressure releasing hole;
The 32-spool;

The specific embodiment
See also Fig. 1,2,3, they are structural representations of a kind of safety anti-explosive pressure cooker of the utility model.As shown in the figure: it comprises the pot body 1 that is connected with pot cover 2, can have securing member between this pot cover 2 and the pot body 1.Be embedded with a safe purge valve 3 on this pot body 1, this safe purge valve 3 can be arranged on the pot cover 2.
As Fig. 2,3, this safe purge valve 3 comprises a valve body 31, and this valve body 31 has hollow cavity, is communicated with in the upper end closed of valve body 31, lower end and the pot body 1 and the lower ending opening place is provided with and keeps off edge 311, has pressure releasing hole 312 on valve body 31 1 sidewalls; One spool 32 is arranged in the hollow cavity of valve body 31, the height of spool 32 is less than the height of valve body 31 hollow cavities, spool 32 also has hollow cavity, and spool 32 upper end closeds, lower end are communicated with the pot body by valve body 31 lower ending openings, also have a pressure releasing hole 321 on the sidewall of this spool 32; The pressure releasing hole 321 of spool 32 and the pressure releasing hole 312 of valve body 31 are on same axis, and the pressure releasing hole 312 of this valve body 31 is smaller or equal to the pressure releasing hole 321 of spool 32.
And the position of pressure releasing hole 321 is lower than pressure releasing hole 312; Has a flexible member 33 between the upper surface of these spool 32 upper surfaces and valve body 31 inner chambers.
During use, when pot inner pressure just often, the situation of safe purge valve 3 is as shown in Figure 2.When pot inner pressure was excessive, as Fig. 3, spool 32 was pushed upwardly with compression elastic element 33, so that the pressure releasing hole 321 of spool 32 is relative with pressure releasing hole 312 positions of valve body 31, at this moment the excessive pressure in the pot can be discharged.When pot inner pressure recovers normal, the restoring force by flexible member 33 is then got back to position among Fig. 2 with spool 32.
Being preferred embodiment of the present utility model only in sum, is not to be used for limiting practical range of the present utility model.Be that all equivalences of doing according to the content of the utility model claim change and modification, all should be technology category of the present utility model.
