Abstract
The utility model discloses a pot cover with an automatic exhaust function. The pot cover comprises a pot cover body, a handle and an exhaust valve. The exhaust valve is made of silica gel material. When air pressure in the pot cover is high, the exhaust valve is lifted automatically to exhaust high-pressure steam till pressure in the pot cover is not high enough to lift the exhaust valve, then the exhaust valve falls back automatically, and therefore the pressure in the pot cover can be maintained within a certain range. The pot cover can be placed vertically through the handle, and therefore space of a kitchen table can be effectively saved.
Description
Technical field
The utility model relates to a kind of pot cover, is specifically related to a kind of pot cover with automatic vent function.
Background technology
Pot cover common on the existing market is directly processed a circular port as steam port at the pot cover body mostly, the shortcoming of the steam port of this kind form is: when firm use pot cover, the pot cover internal gas pressure is lower, but the interior gas of pot cover this moment still can carry out energy exchange by steam port and the external world, thereby influence the rising of kettle temperature, cause energy waste.
Existing most pot cover can only will laterally be shelved on the platform of kitchen when culinary art is finished simultaneously, and the occupation space area is big when causing pot cover to be shelved.If pot cover is faced up reverse side down, can make the steam on the pot cover or spatter greasy dirt on the pot cover inner surface etc. to drop on the platform of kitchen when laterally shelving simultaneously, influence the cleaning of kitchen platform.
Summary of the invention
In view of this, the utility model provides a kind of pot cover with automatic vent function, and this pot cover is by installing the air bleeding valve that silica gel is made in the steam port position, can guarantee that the pot cover air pressure inside is maintained within a certain range, and lower at the pot cover internal gas pressure, not exhaust, thus effectively save the energy.
The pot cover with automatic vent function that the utility model provides comprises pot cover body and handle, it is characterized in that, also comprises air bleeding valve; Depart from its center position on the described pot cover body and be processed with circular port.Described air bleeding valve is the end opening that silica gel material is made, the cylindrical sleeve of end sealing; Openend in this cylindrical sleeve is processed with shaft shoulder A, is processed with shaft shoulder B between openend and the blind end.Described air bleeding valve is positioned at the circular port on the pot cover body, and its blind end is positioned at the outer surface of pot cover body, and openend is positioned at the inner surface of pot cover body; Cylindrical diameter and the diameter of described circular port of described air bleeding valve between shaft shoulder A and shaft shoulder B is identical, and air bleeding valve can move up and down in this scope.The cylindrical periphery of described air bleeding valve between shaft shoulder A and shaft shoulder B is processed with venthole.
Centre position at this external surface of pot cover is equipped with handle, and an end and the pot cover body of described handle are affixed, and the other end is along the radially extension of pot cover body.
Form two feets after the end indent of described handle radial level elongated end, the distance range of the end face of described two feets and pot cover body central point is not less than 1/2nd of pot cover body radius, is not more than the radius of pot cover body; When pot cover was vertically placed, the edge of described two feets and pot cover body formed supported at three point.
Venthole on the described air bleeding valve evenly distributes along the circumferencial direction of air bleeding valve.
Venthole on the described air bleeding valve is bar hole.
Minimum range between described handle and pot cover body upper surface is not less than 5cm.
Beneficial effect:
(1), by in the steam hole of pot cover, air bleeding valve being installed, at the initial stage of using pot cover, kettle temperature is lower, the intrinsic pressure of pot cover this moment is suitable with ambient pressure, not exhaust of air bleeding valve, the intrinsic high-temperature gas of pot cover do not exchange with ambient atmos, thereby kettle temperature is risen rapidly; And after the intrinsic pressure of pot cover and ambient pressure difference were enough to support air bleeding valve, air bleeding valve was mentioned automatically, the starting degassing function, and can guarantee that the intrinsic pressure of pot cover and ambient pressure difference are maintained within a certain range.
(2) pot cover in the utility model can vertically be placed when not using, and can effectively save the usage space of kitchen platform.

The specific embodiment
Below in conjunction with the accompanying drawing embodiment that develops simultaneously, the utility model is described in detail.
Present embodiment provides a kind of pot cover with automatic vent function, and its structure comprises pot cover body 1, handle and air bleeding valve 2 as shown in Figure 1.This pot cover reaches automatic vent behind the certain value by can air bleeding valve 2 making the pot cover air pressure inside, thereby guarantees that the pot cover air pressure inside is maintained within a certain range, and pot cover can vertically be placed by handle.
Depart from its center position on the described pot cover body 1 and be processed with the round steam hole.The air bleeding valve 2 that silica gel material is made is positioned at steam hole.Described air bleeding valve 2 is an end opening, the cylindrical sleeve of end sealing; Be processed with shaft shoulder A3 at this cylindrical sleeve openend, its place, axial centre position is processed with shaft shoulder B4.This cylindrical sleeve is installed in the steam hole, makes its blind end be positioned at the outer surface of pot cover body 1, openend is positioned at the inner surface of pot cover body 1.Cylindrical diameter and the diameter of steam hole of described air bleeding valve 2 between shaft shoulder A3 and shaft shoulder B4 is identical, and air bleeding valve 2 can move up and down in this scope.Air bleeding valve 2 its circumferencial direction of cylindrical outer circumference surface upper edge between shaft shoulder A3 and shaft shoulder B4 is evenly distributed with axial bar hole.Under normal condition, air bleeding valve 2 is under the gravity effect, and its shaft shoulder B4 contacts with the outer surface of pot cover body 1; Use pot cover when in culinary art after, the pressure in the pot cover body 1 increases gradually, and behind the gravity greater than air bleeding valve 2, air bleeding valve 2 is mentioned automatically when the pressure in the pot cover body 1 and ambient pressure difference, by the bar hole exhaust between shaft shoulder A3 and the shaft shoulder B4.And along with the pressure in the pot cover body 1 and ambient pressure difference increase, distance between the outer surface of shaft shoulder B4 and pot cover body 1 increases, the capacity of air bleeding valve 2 increases, and when the shaft shoulder A3 of air bleeding valve 2 contacted with the inner surface of pot cover body 1, it is maximum that the capacity of air bleeding valve 2 reaches.
Centre position at pot cover body 1 outer surface is equipped with handle, and an end and the pot cover body 1 of described handle are affixed, and the other end extends along the radial level of pot cover body 1.Can vertically place in order to make pot cover body 1, thereby save platform space, kitchen, form two feets behind the end concave that handle is radially extended, the distance of the end face of two feets and pot cover body 1 central point is between the radius of 1/2nd and pot cover body 1 of pot cover body 1 radius, get this distance in the present embodiment and be the radius of pot cover body 1, thereby when guaranteeing that pot cover is vertically placed, the edge formation supported at three point of two feets and pot cover body 1 can vertically be placed pot cover.
Can do not scalded by pot cover body 1 when picking up pot cover for assurance by handle, the minimum range between described handle and pot cover body 1 upper surface should be not less than 5cm.
In sum, more than be preferred embodiment of the present utility model only, be not for limiting protection domain of the present utility model.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
