Authorization Notice No. is that the Chinese utility model patent of CN204384035U discloses a kind of vacuum crisper, comprise tank body, base and upper cover, described tank body is connected with described upper cover by described base, cover on described and be provided with hood-opening device and first by gland, described hood-opening device is connected with described upper cover by gland respectively with described first, described base is provided with air bag and the first check valve, and described first check valve is connected with described air bag by gland respectively with described first.The vacuum crisper of this patent, although its good seal performance, swept volume is large, and fresh keeping time is long, its complex structure, and productive costs is higher, and upper cover takes up room greatly, affects the storage space of food.
Utility model content
The vacuum crisper that the utility model provides a kind of sealing effectiveness to improve, its main purpose is that the leak tightness overcoming existing vacuum crisper is poor, degree of vacuum is lower, is difficult to make food to keep the shortcoming such as fresh for a long time.
The utility model adopts following technical scheme:
A kind of vacuum crisper of sealing effectiveness improvement, comprise box body and the lid be connected on box body that is sealed and matched, described lid is provided with one and vacuumizes hole, described vacuumizing on hole is sealedly connected with an elastic button stopper, this elastic button stopper is provided with a gap, described lid is also provided with a button be connected above elastic button stopper, described gap is opened and tray interior is communicated with air under button effect; When tray interior is in negative pressure, described gap tight closure under barometric pressure effect makes tray interior and isolated from atmosphere.
Further, in the technical scheme of the vacuum crisper of above-mentioned a kind of sealing effectiveness improvement, a downward opening central blind hole is offered in described elastic button stopper middle and lower part, the middle and upper part of this elastic button stopper offers described gap, this gap is through to the top of central blind hole, the lateral wall of described central blind hole be provided with one with the described seal groove vacuumizing hole sidewall and be connected.
Further, in the technical scheme of the vacuum crisper of above-mentioned a kind of sealing effectiveness improvement, the top in described gap is provided with a pressing groove, and described button is provided with a cooperation top and is pressed in thimble on described pressing groove.
Further, in the technical scheme of the vacuum crisper of above-mentioned a kind of sealing effectiveness improvement, the middle and upper part of described elastic button stopper is boss-shaped.
Further, in the technical scheme of the vacuum crisper of above-mentioned a kind of sealing effectiveness improvement, described elastic button stopper adopts silica gel or rubber to make.
From the above-mentioned description to the utility model structure, compared to the prior art, the utility model tool has the following advantages: the vacuum crisper of this structure, vacuumize on hole and be sealedly connected with an elastic button stopper, elastic button stopper offers a gap, utilize the button down pressing effect be located at above gap to be opened in gap, tray interior is communicated with air, carries out vacuumizing or pressure release; And when tray interior is in negative pressure, gap tight closure under barometric pressure effect of elastic button stopper, makes tray interior and isolated from atmosphere, play the effect keeping vacuum for a long time.Therefore the leak tightness of vacuum crisper of the present utility model is good, degree of vacuum is high, and food and air can be made to keep for a long time isolating, and in addition, the structure of this vacuum crisper is simple, be convenient to produce, and productive costs is low, is suitable for using on a large scale.

Detailed description of the invention
Detailed description of the invention of the present utility model is described with reference to the accompanying drawings.In order to complete understanding the utility model, many details are described below, but to those skilled in the art, also can realize the utility model without the need to these details.
A vacuum crisper for sealing effectiveness improvement, with reference to Fig. 1, comprises box body 10 and the lid 20 be connected on box body 10 that is sealed and matched.With reference to Fig. 2 and Fig. 3, lid 20 is provided with one and vacuumizes hole 21, and this vacuumizes on hole 21 and is sealedly connected with an elastic button stopper 22, and elastic button stopper 22 adopts silica gel or rubber to make, to make it good with the sidewall connection sealing vacuumizing hole 21.The middle and upper part of this elastic button stopper 22 is boss-shaped, and offers a gap 221, and a downward opening central blind hole 222 is offered in the middle and lower part of elastic button stopper 22, and gap 221 is through to the top of central blind hole 222 and is connected with central blind hole 222.The lateral wall of central blind hole 222 be provided with one with the seal groove 223 vacuumizing hole 21 sidewall and be connected.
With reference to Fig. 2 and Fig. 3, above-mentioned lid 20 is also provided with a button 23 be connected above elastic button stopper 22, the top in above-mentioned gap 221 is provided with a pressing groove 224, and button 23 is provided with a cooperation top and is pressed in the thimble 231 pressed on groove 224, so that the operation of user.Opening under button 23 acts on when gap 221 makes box body 10 inside be communicated with air; When box body 10 inside is in negative pressure, gap 221 tight closure under barometric pressure effect makes box body 10 inside and isolated from atmosphere.
The vacuum crisper of this structure, during use, is placed in food in box body 10, covers lid 20, and button 23 is done in order to make the gap 221 of elastic button stopper 21 open downwards, and connect vacuum extractor and outwards bleed, air is discharged from gap 221; When degree of vacuum reaches fresh-keeping requirement, stop bleeding, because the pressure of box body 20 inside is less than external pressure, therefore the pressure of air acts on the elastic button stopper 21 of both sides, gap 221, by gap 221 crush seal, plays pressure maintaining effect.During pressure release, press the button 23, the elastic button stopper 21 of both sides, gap 221 is squeezed.
Above are only detailed description of the invention of the present utility model, but design concept of the present utility model is not limited thereto, all changes utilizing this design the utility model to be carried out to unsubstantiality, all should belong to the behavior of invading the utility model protection domain.
