Description

Pressure cooker floater type air guide structure and pressure cooker

Technical field

The present invention relates to pressure cooker field, in particular to a kind of pressure cooker floater type air guide structure and pressure cooker.

Background technology

Electric pressure cooking saucepan needs before pressure first discharged by the gas in pot, the gas of discharging in pot is mainly realized by float.At present, have exhaust passage in the float that electric pressure cooking saucepan uses, silica gel sealing ring is equipped with in bottom.When pot inner pressure is less than 4KPa, insufficient pressure is with by float jack-up, and now, the gas in pot is discharged by float.When pot inner pressure is greater than 4KPa, pot inner pressure overcomes the gravity of float by float jack-up, realizes sealing, and simultaneously float covers a hole or groove in passing after lifting, thus makes cylinder cap can not rotate realization to have under pressure pattern and can not uncap.

But, technique scheme has following defect: because the gas in pot enters upper cover by float, and the upper cover of electric pressure cooking saucepan is all generally sealing, therefore, the gas arranged into upper cover cannot be discharged, and can become water, and the inside of float inner cap cannot be cleared up after condensation, time has peculiar smell after having grown, and this is more obvious after the functions such as use stews especially.

Summary of the invention

There is provided in the embodiment of the present invention that a kind of structure is simple, cost is low, can avoid accumulating between inner cap and cover pressure cooker floater type air guide structure and pressure cooker that gas causes peculiar smell.

For solving the problems of the technologies described above, the embodiment of the present invention provides a kind of pressure cooker floater type air guide structure, comprising: float and inner cap, inside covers the position corresponding with float and is provided with the first exhaust passage be in communication with the outside.

As preferably, pressure cooker floater type air guide structure also comprises cover, is provided with the second exhaust passage; First exhaust passage is in communication with the outside after coordinating with the second exhaust passage.

As preferably, the first exhaust passage and the second exhaust passage are pyramidal structure, and the first exhaust passage and the second exhaust channel coaxial ground are arranged.

As preferably, the lower end of the pyramidal structure of the second exhaust passage is inserted in the upper end of the pyramidal structure of the first exhaust passage.

As preferably, the axis of the import of relative first exhaust passage of axis of the outlet of the first exhaust passage has the first horizontal-shift distance, and float is arranged on the below of import.

As preferably, the axis of the import of relative second exhaust passage of axis of the outlet of the second exhaust passage has the second horizontal-shift distance.

As preferably, the outlet of the first exhaust passage and the outlet of the second exhaust passage are arranged along the direction skew gradually away from the import of the first exhaust passage successively.

As preferably, the import of the second exhaust passage is inserted in the outlet of the first exhaust passage.

Present invention also offers a kind of pressure cooker, comprise above-mentioned pressure cooker floater type air guide structure.

Owing to have employed technique scheme, the present invention when not increasing new parts, can draw the gas that float is discharged, avoiding the accumulation of gas between inner cap and cover, have the advantages that structure is simple, cost is low preferably.

Detailed description of the invention

Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail, but not as a limitation of the invention.

Please refer to Fig. 1 to Figure 11, the invention provides a kind of pressure cooker floater type air guide structure, comprising: float 1 and inner cap 2, position corresponding with float 1 on inner cap 2 is provided with the first exhaust passage 3 be in communication with the outside.

As shown in Figure 1, when pressure cooker normally works, steel lid 6 is buckled on outer pot, forms airtight space by sealing ring and interior pot 8.Communicated with the external world by blast pipe 7, float 1, be exhausted and pressure release effect.

Wherein, float 1 can be up and down, and when without pressure, float 1 falls thus communicates with the external world; When pressure reaches enough large, float 1 moves upward, and now plays sealing function by the sealing ring of its end and steel lid 6, and forms confined space.

Like this, when starting there is pressure in pot, gas can be discharged from float 1.The gas of discharging can be discharged to outside pot by the first exhaust passage 3, thus the gas solving float place discharge in prior art can go to relative airtight space between inner cap with cover, so that after a period of time, taste entrained in gas can remain in the problem in pot cover.

In a preferred embodiment, pressure cooker floater type air guide structure also comprises cover 4, is provided with the second exhaust passage 5; First exhaust passage 3 is in communication with the outside after coordinating with the second exhaust passage 5.Like this, coordinated the passage of rear formation by the first exhaust passage 3 with the second exhaust passage 5, gas can be discharged outside pot.

As Fig. 1 to Fig. 5, in a preferred embodiment, the first exhaust passage 3 and the second exhaust passage 5 are pyramidal structure, and the first exhaust passage 3 and the second exhaust passage 5 are arranged coaxially.Like this, form an exhaust passage vertically extended, and the narrowing gradually from the bottom to top of this exhaust passage, can prevent foreign from entering between inner cap and cover, simultaneously, such structure also makes the present invention when not increasing new parts, can realize the function of exhaust, and installing also very convenient.

Preferably, as Fig. 1 to Fig. 5, the lower end of the pyramidal structure of the second exhaust passage 5 is inserted in the upper end of the pyramidal structure of the first exhaust passage 3.Like this, the first exhaust passage and the second exhaust passage link up mutually, prevent gas from being escaped in the space between inner cap and cover by junction therebetween, cause peculiar smell.

As Fig. 6 to Figure 11, in another preferred embodiment, the axis of the import of relative first exhaust passage 3 of axis of the outlet of the first exhaust passage 3 has the first horizontal-shift distance, and float 1 is arranged on the below of import.Adopt such structure, make the exhaust passage formed have the track of bending, therefore, between outside foreign matter inner cap more difficult to get access and cover.Meanwhile, such structure also makes the present invention when not increasing new parts, can realize the function of exhaust, and installing also very convenient

As Fig. 6 to Figure 11, in a preferred embodiment, the axis of the import of relative second exhaust passage 5 of the axis of the outlet of the second exhaust passage 5 has the second horizontal-shift distance.As Fig. 6 to Figure 11, more preferably, the outlet of the first exhaust passage 3 and the outlet of the second exhaust passage 5 are arranged along the direction skew gradually away from the import of the first exhaust passage 3 successively.

Preferably, the import of the second exhaust passage 5 is inserted in the outlet of the first exhaust passage 3.Like this, the first exhaust passage and the second exhaust passage link up mutually, prevent gas from being escaped in the space between inner cap and cover by junction therebetween, cause peculiar smell.

Certainly, be more than the preferred embodiment of the present invention.It should be pointed out that for those skilled in the art, under the prerequisite not departing from its general principles, can also make some improvements and modifications, these improvements and modifications are also considered as protection scope of the present invention.
