Abstract

The utility model discloses a silica gel automatic exhaust valve, which comprises a silica gel valve body, wherein the section of the silica gel valve body is transverse H-shaped; the middle part of the transverse H-shaped silica gel valve body is provided with a through hole; the top end of the through hole is hermetically connected with a silica gel thin sheet; an exhaust port is formed in the silica gel thin sheet; and the thickness of an exhaust port of the silica gel thin sheet is less than the thickness of the periphery of the exhaust port. The exhaust port is a crossed crack. The gluing part at the exhaust port of the silica gel valve body is relatively thin; the exhaust port in the shape of the crossed rack is formed; when a cooking vessel is pressed, the crack of the silica gel thin sheet is increased, and air is discharged through the crack; and when the pressure in the cooking vessel is weakened, the toughness of the crack of the silica gel thin sheet rebounds for airtightness, thereby realizing automatic closing and exhaust.

Description

The silica gel automatic control pressure vent

Technical field:

The utility model relates to the Decompression valves field, is specifically related to a kind of silica gel automatic control pressure vent.

Background technique:

Present automatic control pressure vent is the metal manufacturing, and complex structure, and Safety performance is low, and is blocked easily during culinary art, hides easily dirt, cleans extremely loaded down with trivial details.

The model utility content:

The purpose of this utility model provides a kind of silica gel automatic control pressure vent, can automatically close, exhaust.

The utility model is achieved by the following technical programs: the silica gel automatic control pressure vent, comprise the silica gel valve body, the section of described silica gel valve body is I-shaped, the middle part of silica gel valve body is through hole, described through hole end sealing is connected to silica gel thin slice, establish relief opening in the described silica gel thin slice, exhaust ports thickness is less than the thickness of relief opening periphery.

Described relief opening is the cross crack.

A little less than the glue position relative thin of the utility model silica gel valve body exhaust ports, and offer the relief opening in cross crack, when the cooking utensil pressurized, the crack of silica gel thin slice increases, gas is discharged from the crack, and when the pressure in the cooking utensil weakens, the tough elastic recoil in the crack of silica gel thin slice, thereby envelope gas is realized automatically pass, exhaust.

Embodiment:

Below be to further specify of the present utility model, rather than to restriction of the present utility model.

Embodiment 1:

Shown in Fig. 1,2,3,4,5, the silica gel automatic control pressure vent, comprise silica gel valve body 1, the section of described silica gel valve body 1 is I-shaped, the middle part of described I-shaped silica gel valve body 1 is through hole 11, described through hole 11 end sealings are connected to silica gel thin slice 2, establish relief opening 21 in the described silica gel thin slice 2, and the relief opening 21 place glue position thickness of described silica gel thin slice 2 is less than the thickness of relief opening 21 peripheral glue positions.

Described relief opening 21 is the cross crack.

This model utility can be installed on the cooking utensil lid.
