Abstract

The utility model discloses a vertical type automatic air exhaust pot cover, which comprises a pot cover body (1). The vertical type automatic air exhaust pot cover is characterized in that an air exhaust opening (2) is arranged on the pot cover body (1), a handle (3) is fixedly connected with the pot cover body (1) at the air exhaust opening (2), an air exhaust hole (4) is arranged on a side surface of the handle (3) and is communicated with an inner cavity (5) of the handle (3), a baffle (6) is hinged in the inner cavity (5), and the lower end surface of the baffle (6) is connected with a memory alloy spring (7). The vertical type automatic air exhaust pot cover has the advantages that the vertical type automatic air exhaust pot cover is smart in structure and reasonable in design, after steam is generated in a pot, the air exhaust openings are opened automatically so that steam is discharged, environmental sanitation and service safety are guaranteed, and the like.

Description

Last following formula automatic vent pot cover

Technical field

The utility model relates to a kind of pot cover, particularly a kind ofly can open exhaust outlet automatically, thereby the water vapour in the pot is discharged, and overflows to prevent pot interior soup juice, can guarantee environmental sanitation and automatic vent pot cover safe in utilization.

Background technology

People are when the culinary art activity such as steaming, boil, and when the soup juice in the pot was in fluidized state, the pot cover that matches with the pot body tended to jack-up under the effect of steam in pot; The interior liquid such as soup juice of pot this moment just can overflow from the slit between pot cover and the pot body, not only can pollute environment on every side, but also might scald the operating personnel of culinary art; The more important thing is; These liquid might extinguish the blaze or put out by water, cause the leakage of combustion gas, exist bigger potential safety hazard.In order to address this problem, the operator just needs frequent opened pot, and the vapor evolution in the pot is gone out, and has increased the amount of labour; Perhaps directly pot cover is removed the activity of culinary art, and the impurity of doing like this in the environment such as dust possibly fallen in the pot, influence dietetic hygiene.In order to address the above problem, people's invention there emerged a the anti-overflow pot cover of kind of version, and these anti-overflow pot covers mainly are that two kinds of forms constitute: the hole of 1, often opening naturally.Shortcoming when water does not seethe with excitement in pot pot cover also be to communicate with the external world, thereby can cause the passage of unnecessary heat to waste the unnecessary energy.2, rely on steam with the seal cover jack-up on the pore.Shortcoming is that seal cover must just can back down it this disabler when sealing lid has the adhesion of part soup juice in addition when steam reaches certain ejecting force.Therefore need a kind of novel pot cover that can address the above problem now.

Summary of the invention

The utility model is in order to solve the above-mentioned deficiency of existing in prior technology, and it is ingenious to propose a kind of structure, reasonable in design, can in pot, produce steam after, exhaust outlet is opened automatically and steam is discharged, to guarantee environmental sanitation and automatic vent pot cover safe in utilization.

The technical solution of the utility model is: a kind of following formula automatic vent pot cover of going up; Comprise pot cover body 1, it is characterized in that: offer exhaust outlet 2 on the described pot cover body 1, be fixedly connected jug 3 with pot cover body 1 at exhaust outlet 2 places; The side of handle 3 offers steam vent 4; Steam vent 4 is connected with the inner chamber 5 of handle 3, is hinged with catch 6 in the inner chamber 5, is connected with memory alloy spring 7 in the lower surface of catch 6.

Also be socketed with common spring 8 outside the described memory alloy spring 7.

The utility model is compared with prior art, has following advantage:

The automatic vent pot cover of this kind of version; It is simple in structure; Design ingeniously, its special construction has determined it can the inner chamber of pot be communicated with through exhaust outlet with extraneous, and the inner steam of pot is discharged among the external world through exhaust outlet; Can effectively prevent pot cover jack-up under the effect of steam like this, the situation that causes soup juice to overflow; The more important thing is; It has creatively increased memory alloy spring in the structure of exhaust outlet; It is (when the steam in the pot contact with memory alloy spring) automatic contraction when environment reaches uniform temperature around, and exhaust outlet is opened voluntarily, need not cook and carries out any operation.This automatic vent pot cover can prevent effectively that pot interior soup juice from overflowing, thereby has guaranteed the health of cooking environments, also can eliminate because of soup juice to overflow coal gas (natural gas) the poisoning hidden danger that extinguishes the blaze and cause.Therefore we can say that this automatic vent pot cover has possessed multiple advantage, be particularly suitable in kitchen tools producing, processing and selling field, applying that its market prospects are very wide.

Fig. 2 is the A portion enlarged drawing of Fig. 1.

Fig. 3 is the structural representation of the utility model embodiment exhaust open state.

The specific embodiment

Below with the specific embodiment of accompanying drawings the utility model.Like Fig. 1, Fig. 2, shown in Figure 3: a kind of following formula automatic vent pot cover of going up, comprise pot cover body 1, on pot cover body 1, offer exhaust outlet 2; Be fixedly connected jug 3 at exhaust outlet 2 places with pot cover body 1, offer steam vent 4 in the side of handle 3, this steam vent 4 is connected with the inner chamber 5 of handle 3; In inner chamber 5, be provided with the catch 6 that can swing up and down; This catch 6 is hinged among the handle 4, and inner chamber 5 is divided into upper and lower two chambers, is provided with memory alloy spring 7 in the lower surface of catch 6; In the outer ring of this memory alloy spring 7, also be socketed with common spring 8.

The course of work of the last following formula automatic vent pot cover of the utility model embodiment is following: the pot cover of present embodiment is placed on pot body; Originally, under the effect that common spring 8 pulls, catch 6 is in level; With exhaust outlet 2 sealing, the passage that is not communicated with between pot nside and the external world;

When the liquid in the pot body (soup juice) after producing steam under the state heated; Steam can get into the bottom of inner chamber 5 through exhaust outlet 2; Take place directly to contact with memory alloy spring 7, deformation takes place in memory alloy spring 7, catch 6 is upwards boosted (power during memory alloy spring 7 distortion is greater than the pulling force of 8 pairs of catch 6 of common spring); At this moment; Pot nside communicates with the external world through the steam vent 4 that is arranged on handle 3 sides, and steam just can be discharged among the external world through exhaust outlet 2, inner chamber 5 and steam vent 4 like this, has played the effect of automatic unlatching exhaust outlet 2;

When the heating source of pot body 1 removes; Temperature in the pot body 1 reduces gradually, and when the temperature around the memory alloy spring 7 dropped to its deformation temperature, memory alloy spring 7 began to shrink; Like this under the acting in conjunction of memory alloy spring 7 and common spring 8; Catch 6 returns to horizontal level, again pot nside is sealed, and can play the effect of insulation.
