Abstract
The utility model discloses an anti-overflowing pot cover for preventing the liquid in the pot from overflowing to the pot and the cooking stove, pertaining to the pot cover, provided to solve the problems in the present anti-overflow pot cover with bad anti-overflow effect and high production cost. The anti-overflow cover in which the inner surface is the concave surface and the top-down direction along the upper top cover's surface is provided with a groove arranged with an air hole on the upper part, a reflowing valve on the lower part. With the advantages of the simple structure, low production cost, the convenient operation, a good anti-overflow effect, the utility model can be widely applied to many fields such as the boiled porridge and the boiled soup.
Description
Technical field
The utility model relates to a kind of pot cover, relates in particular to a kind ofly can prevent overflow anti-overflow pot cover on the pot body and the kitchen range top of pot interior liquid.
Background technology
Commonly used various pots are being cooked congee or during Baoshang, a water or a foam regular meeting in the pot flow out, and flow on pot body and the kitchen range top in the daily life.This not only cleans inconvenience, and, flow out that pot is outer to cause electric leakage if overflow the soup that takes, perhaps cause stove fire to extinguish and cause gas leakage, will produce potential safety hazard.
In order to address the above problem, several air-vents are set on pot cover usually, adopt exhaust step-down mode to prevent overflowing of pot interior liquid, in addition, vinyl cover can also be set on pot cover prevent to overflow.But, only utilize air-vent to prevent that spill-over effects is relatively poor, utilizing vinyl cover to prevent to overflow has then increased production cost, and owing to increased vinyl cover, makes pot cover inconvenient when cleaning.
The utility model content
At the existing problem and shortage of above-mentioned existing anti-overflow pot cover, the purpose of this utility model provides a kind of simple in structure, and production cost is lower, and the anti-overflow effect is anti-overflow pot cover preferably.
The utility model is achieved in that
The inner surface of this anti-overflow pot cover is a concave surface, is provided with groove at the pot cover upper surface along from top to bottom direction, and the top of described groove is provided with air-vent, and the bottom of described groove is provided with return port.
Owing to adopted said structure, compare with existing anti-overflow pot cover, anti-overflow pot cover described in the utility model in use, when the air pressure in the pot reaches certain critical condition, can play the effect of step-down anti-overflow by being arranged on air-vent and the return port exhaust on the pot cover; If the material in the pot overflows air-vent, overflow can flow to return port along backflash, and flows back in the pot via return port, so overflow can arbitrarily not flow at the pot cover upper surface, has kept the cleaning of pot cover; The inner surface of pot cover is a concave surface, and the material that has boiled is flowed back in the pot again along inner surface, prevents from effectively to overflow.So the utlity model has following beneficial effect: simple in structure, production cost is lower, easy to use, the anti-overflow effect is better.
Description of drawings
Fig. 1 is the schematic top plan view of anti-overflow pot cover described in the utility model;
Fig. 2 is the schematic perspective view of anti-overflow pot cover shown in Figure 1.
The specific embodiment
Below in conjunction with accompanying drawing, further specify technical characterictic of the present utility model and function characteristics, purpose is that the utility model can be described better, but is not to be used for limiting protection domain of the present utility model.
See figures.1.and.2, the inner surface of anti-overflow pot cover 1 described in the utility model is a concave surface, is provided with groove 3 at the pot cover upper surface along from top to bottom direction, and the top of described groove is provided with air-vent 2, and the bottom of described groove is provided with return port 4.Described groove is arranged on the pot cover upper surface uniformly, and its cross section can be arch, and the length of groove and width and quantity can be provided with as required.Air-vent can be circular, shapes such as rhombus, and number can be provided with several with the difference of shape.An air-vent can be set on one groove, two or three air-vents also can be set.
For the anti-overflow better effects if, described air-vent is arranged on the top on described groove top, and described return port is arranged on the bottom of described groove bottom.Prolonged the material that overflows in the pot like this in the time that the pot cover upper surface flows, cooling-down effect is better.
For the better effects if that refluxes, described return port is arranged on the lower edge of described pot cover.In the production process, groove is the edge that starting point extends to pot cover always with the air-vent, cooperates upper grooves to cut out corresponding breach in the pot cover lower edge, and this breach promptly is a return port.
For the ease of processing and use, the cross section of described groove is an arch.
In order to obtain to reflux preferably effect, the preferred 10-20mm of above-mentioned groove diameter is for the ease of using the further preferred 13-15mm of above-mentioned groove diameter.
In order to obtain anti-overflow effect preferably, the preferred 8-12mm of above-mentioned air-vent diameter is for the ease of using the further preferred 10-12mm of above-mentioned air-vent diameter.
For the better effects if that refluxes, above-mentioned return port is semicircular breach, and the preferred 10-20mm of diameter is for the ease of using the further preferred 10-12mm of above-mentioned return port diameter.
Above-mentioned anti-overflow pot cover in use when the air pressure in the pot reaches certain critical condition, can play the effect of step-down anti-overflow by being arranged on the air-vent on the pot cover and the return port exhaust at edge; The pot cover top reasonably uses the principle of the drainage of building canals, the arcuate recess that with the air-vent is the starting point setting is a backflash, and backflash is equipped with corresponding return port, makes the overflow in the pot can flowing back in the pot along the backflash orientation, can arbitrarily not flow, keep the cleaning of pot cover; The pot cover inner surface is a concave surface, and soup juice is flowed back in the pot again, prevents from effectively to overflow.The advantage of above-mentioned anti-overflow pot cover is: simple in structure, production cost is lower, easy to use, anti-overflow is effective.
The above-mentioned specific embodiment is illustrated the utility model with preferred embodiment, but the example of this visualization of just lifting for the ease of understanding should not be considered to be the restriction to the utility model scope.Equally, according to the description of the technical solution of the utility model and preferred embodiment thereof, can make various possible being equal to and change or replacement, and all these changes or replacement all should belong to the protection domain of the utility model claim.
