Abstract

The utility model discloses an automatic overflow preventing pot cover. The utility model is characterized in that the top of the pot cover is provided with an overflow preventing hole; a small overflow preventing cover is covered on the overflow preventing hole; a fixing bracket which is connected with the main body of the pot cover and is provided with holes is in the overflow preventing hole; one end of a combined spring is connected to the small overflow preventing cover, and the other end is connected to the fixing bracket. The utility model can automatically prevent the overflow of boiled liquid and is a very practical novel pot cover.

Description

Automatic anti-overflow pot cover

The utility model relates to the daily necessities pot cover.

Usually, people cook congee, soups food and heating liquid at work, when boiling water if the cooking stove limit is unmanned, food or liquid then can overflow container outside, gently then want the clean container and the kitchen range top, heavy then liquid that overflow extinguishes stove fire or gas range, make pernicious gases such as coal gas jeopardize personal safety.

The purpose of this utility model provides a kind of simple in structurely, can prevent liquid spill automatically, avoids the pot cover that has an accident.

For achieving the above object, solution of the present utility model is: open a hole at the pot cover top, an anti-overflow tegillum is arranged on the hole, tegillum is controlled by cluster spring, can be in to close and open two states.When food or liquid during in heating, tegillum is closed, so that food or liquid are accelerated boiling; After food or liquid were boiled, tegillum was opened automatically, gases at high pressure was overflowed, in order to avoid food or liquid overflow container.

Control element cluster spring of the present utility model adopts new function material marmem and stainless steel extension spring to manufacture.Because the characteristics of marmem are, when being in low temperature phase (martensitic phase), the yield stress of material is lower, and material itself is softer; When being in high temperature phase (parent phase), the yield stress of material is higher, and material itself is harder; Simultaneously, when material is converted to the high temperature phase time mutually by low temperature, the profile of material also fades to the shape of high temperature phase time, i.e. SME.

The utility model has the advantages that: the liquid after preventing from automatically to boil overflows outside the pot, and the control element cluster spring is simple in structure, and is easy to use.Automatically anti-overflow pot cover can be used metal, also can manufacture with pottery.

Below in conjunction with accompanying drawing, the utility model is described in further details.

Accompanying drawing 1 is a structure chart of the present utility model;

Structure chart when accompanying drawing 2 is the utility model unlatching.

Among the figure: 1, anti-overflow tegillum; 2, cluster spring; 3, anti-overflow hole; 4, fixed support; 5, pot cover main body.

Structure of the present utility model is as shown in Figure 1: have anti-overflow hole (3) in the top of pot cover main body (5), be stamped anti-overflow tegillum (1) on anti-overflow hole (3); At anti-overflow hole (3) the inboard fixed support (4) of ining succession and having hole with pot cover main body (5); Cluster spring (2) one ends are connected on the anti-overflow tegillum (1), and the other end is connected on the fixed support (4).

Fixed support of the present utility model has hole on (4), and the hot gas in the time of can making heating in the pot releases, and hot gas makes the marmem in the cluster spring produce phase transformation, backs down anti-overflow tegillum (1).

Cluster spring of the present utility model (2) is combined by marmem and stainless steel extension spring.

During use, the utility model covers on pot or container, when liquid is not boiled in the pot, because the pulling force of the stainless steel spring in the cluster spring (2) is greater than the elastic force of marmem, anti-overflow tegillum (1) is lumped together with pot cover main body (5) tightly, after liquid is boiled, marmem produces phase transformation at high temperature phase time (90～100 ℃), to the pulling force of the elastic force that makes marmem greater than stainless steel spring, anti-overflow tegillum (1) is automatically springed open, gases at high pressure are emitted by anti-overflow hole (3), have prevented to hot plate overflowing of liquid like this.

Claims

1. an automatic anti-overflow pot cover of being made up of pot cover main body etc. is characterized in that, has the anti-overflow hole above the pot cover main body, is stamped the anti-overflow tegillum on it; In the anti-overflow hole, be the fixed support that has hole with pot cover main body connecting place; One end of cluster spring is connected on the anti-overflow tegillum, and the other end is connected on the fixed support.
