Description

A kind of vacuum reservoir

Technical field

The utility model relates to jar, relates in particular to a kind of vacuum reservoir.

Background technology

In the daily life, no matter be food or article, can't preserve for a long time under the normal temperature state that particularly greasy is bred bacterium easily, causes food spoilage to degenerate, article become damp mouldy.

Traditional vacuum reservoir can extract a jar interior air, make tank body keep vacuum state, thereby prevent that article are oxidized and make germ not have life condition to reach the purpose of vacuum freshness retaining, but common poor sealing performance, time one length has air to enter easily, and do not have device and can reflect a jar interior level of vacuum, cause in time to control a jar interior vacuum condition, and cause article rotten; Even have the vacuum reservoir of device for marking, air valve and device for marking are respectively two different structures, and be comparatively complicated, produces to be difficult for.

Summary of the invention

The purpose of this utility model is at the deficiencies in the prior art, and a kind of vacuum reservoir is provided, and can use air pump to take out a jar interior air, good seal performance effectively prevents bacterial reproduction, has superpower moistureproof and mildewproof effect, can deposit food or treasure, can ultra-long time is fresh-keeping never degenerate; Itself has test membrane air valve, can reflect a jar interior level of vacuum, is convenient to timely control, and is simple in structure, is beneficial to a large amount of productions.

For achieving the above object, the utility model by the following technical solutions:

A kind of vacuum reservoir comprises tank body, cover and is installed on air valve in the through hole of cover top that there are some gas ports at the through hole edge of cover inboard, and there is a valve opening at the air valve center, and there is one deck test membrane at the valve opening middle part; Be provided with a cushion rubber between tank body and cover, the cushion rubber size is corresponding with the cover size; The valve body size of air valve is corresponding with hole size; Air valve has a sealing loam cake and a sealing lower cover respectively, and sealing lower cover area size matches with gas port distribution limit area size; Air valve is the silica gel goods.

There are some gas ports at the through hole edge of described cover inboard, can utilize air pump to extract a jar interior air by through hole, to reach vacuum state, controls germ existence, prevents that jar interior article are oxidized, has superpower moistureproof and mildewproof effect; Only need stir air valve when not using, air just can enter in the jar by through hole, removes vacuum state; Gas port can accelerate to bleed and air inlet.

There is a valve opening at described air valve center, and there is one deck test membrane at the valve opening middle part, and under the normal condition, test membrane is convex; When being in vacuum state in the jar, because the relation of atmospheric pressure, test membrane is recess, is convenient to people and understands the interior level of vacuum of jar by test membrane, and timely control jar interior vacuum condition is avoided causing article rotten because placement for a long time enters air; Test membrane and air valve are realized integrated, simple in structure, are beneficial to a large amount of productions.

Be provided with a cushion rubber between described tank body and cover, the cushion rubber size is corresponding with the cover size, the valve body size of air valve is corresponding with hole size, air valve has a sealing loam cake and a sealing lower cover respectively, sealing lower cover area size matches with gas port distribution limit area size, to strengthen a jar interior leak tightness, reach long-time fresh-keeping purpose of guaranteeing the quality.

Described air valve is the silica gel goods, and is elegant in appearance, and firm practicality has vast market prospect.

Compared with prior art, the utlity model has following beneficial effect:

1. can deposit food or treasure, good seal performance effectively prevents bacterial reproduction, has superpower moistureproof and mildewproof effect, long-time fresh-keeping never degenerating;

2. can in time control a jar interior degree of vacuum, avoid causing article rotten, simple in structure because long-time placement enters air, be beneficial to a large amount of productions;

3. elegant in appearance, firm practicality has vast market prospect.

The specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is further described.

As Fig. 1-shown in Figure 4, the utility model vacuum reservoir comprises tank body 1, cover 2 and is installed on air valve 3 in the cover 2 top through holes 21 that there are some gas ports 22 at through hole 21 edges of cover 2 inboards, there is a valve opening 34 at air valve 3 centers, and there is one deck test membrane 31 at valve opening 34 middle parts; 2 of tank body 1 and covers are provided with a cushion rubber 4, and cushion rubber 4 sizes are corresponding with cover 2 sizes; Valve body 32 sizes of air valve 3 are corresponding with through hole 21 sizes; Air valve 3 has a sealing loam cake 35 and a sealing lower cover 33 respectively, and sealing lower cover 33 areas size matches with gas port 22 distribution limit area sizes; Air valve 3 is the silica gel goods.

There are some gas ports 22 at through hole 21 edges of described cover 2 inboards, can utilize air pump to pass through through hole 21 and extract a jar interior air, to reach vacuum state, control germ existence, prevent that jar interior article are oxidized, have superpower moistureproof and mildewproof effect; Only need stir air valve 3 when not using, air just can enter in the jar by through hole 21, removes vacuum state; Gas port 22 can accelerate to bleed and air inlet.

There is a valve opening 34 at described air valve 3 centers, and there is one deck test membrane 31 at valve opening 34 middle parts, and under the normal condition, test membrane 31 is convex; When being in vacuum state in the jar, owing to the relation of atmospheric pressure, test membrane 31 is recess, is convenient to the level of vacuum that people understand in the jar by test membrane 31, and a timely control jar interior vacuum condition is avoided causing article rotten because long-time placement enters air; Test membrane 31 is integrated, simple in structure with air valve 3 realizations, is beneficial to a large amount of productions.

2 of described tank body 1 and covers are provided with a cushion rubber 4, cushion rubber 4 sizes are corresponding with cover 2 sizes, valve body 32 sizes of air valve 3 are corresponding with through hole 21 sizes, air valve 3 has a sealing loam cake 35 and a sealing lower cover 33 respectively, sealing lower cover 33 areas size matches with gas port 22 distribution limit area sizes, to strengthen a jar interior leak tightness, reach long-time fresh-keeping purpose of guaranteeing the quality.

Described air valve 3 is the silica gel goods, and elegant in appearance, firm practicality has vast market prospect.
