Description

Air valve for food fresh-keeping bag

Technical Field

The utility model relates to a ventilation valve field especially relates to food freshness protection package pneumatic valve.

Background

The air valve is generally arranged on the freshness protection package, on one hand, the air valve can prevent external air from entering, on the other hand, the air valve is convenient for discharging air in the package, the air valve commonly used in the market is a gap exhaust valve, one side of a membrane in a valve cavity is fixed, the other side of the membrane is lifted by air flow impact to form a gap, and the gap is discharged along an air vent through the gap.

SUMMERY OF THE UTILITY MODEL

In view of the above, the present invention is directed to a gas valve for a food preservation bag, which solves at least one of the above problems.

The technical scheme of the utility model is that:

food freshness protection package pneumatic valve, including the top cap, the bottom with inhale the piece, establish the first bulge that includes the through-hole on the bottom, the opening part that the air vent is located the bottom outwards extends and forms the second bulge, many air channels are all established to the week side of first bulge and second bulge, the air channel is from first bulge, the week side of second bulge upwards extends to the through-hole opening part, the piece of inhaling of silica gel preparation is the cell body, upwards extend the third bulge in the groove, inhale the piece lock on the second bulge, the third bulge is embedded in the through-hole.

During the installation, this pneumatic valve top cap is located the freshness protection package, inhale the piece and be located outside the freshness protection package, the piece is inhaled on the second bulge to the silica gel of this pneumatic valve, and with third bulge shutoff through-hole, avoid the outside air to flow into in the freshness protection package along the through-hole, gaseous through the air channel gets into in the top cap in the freshness protection package, along the third bulge of through-hole jack-up, under the adsorption of the piece is inhaled to the cell form silica gel, the third bulge suspends on the through-hole, gaseous clearance between third bulge and the through-hole is followed the air channel and is flowed out, the structure is simplified, the cost is reduced, reduce the risk of debris stifled hole, and when bleeding, inhale the piece directly to be located outside the bag because of the silica gel, under the wind pressure, the silica gel inhales the piece and is the suspended state, gaseous through the.

In order to avoid the article collision to inhale the piece, cause to inhale the piece and shift, in further improvement, the holding tank is established at the position that the bottom of the bottom corresponds the through-hole, and the second bulge is arranged in the holding tank, inhales when piece lock is on the second bulge, places in the holding tank to the restriction is in the ascending bag of level article outside to inhaling the collision of piece and shifting, is favorable to docking with the suction nozzle simultaneously.

For reducing weight, first annular is opened at first bulge top, and the through-hole is located the regional of first annular enclosure, and the air channel extends to through-hole department along with first annular, and simultaneously, the regional buffer that forms in annular is located, avoids directly getting into the through-hole from the dust that the air channel got into, improves the gas tightness.

Similarly, a second annular groove is formed in the middle of the top cover corresponding to the through hole, and when the top cover is buckled on the bottom cover, the position of the through hole is arranged in an area defined by the second annular groove to form a buffer area.

And the periphery of the through hole is provided with a third annular groove, so that the weight is reduced by the annular groove structure, and meanwhile, a buffer area is formed, and dust and other impurities are prevented from directly entering the through hole.

In order to guarantee the adsorption effect of inhaling the piece, the fourth ring groove is opened to the third bulge periphery, is the arc wall, and when the cell body lock of inhaling the piece was on the second bulge, the arc wall notch expansion of silica gel material preparation, under the material characteristic, the notch shrink improved and inhaled the absorptive stability of piece.

Because of need vent groove connect through-hole and bag or the outer space of bag, so vent groove outwards extends from first bulge, second bulge periphery, and in order to reduce weight better, adjacent vent groove communicates each other on the peripheral top cap of first bulge, forms fifth ring groove, and when the top cap lock was on first bulge, vent groove and the fifth ring groove intercommunication of first bulge week side formed ventilation channel.

Preferably, the first protrusion, the second protrusion, and the third protrusion are all cylinders, but may also be rectangles or the like.

The utility model has the advantages that: the gas valve simplifies the structure, reduces the cost and is beneficial to quickly extracting the gas in the bag.

Detailed Description

The following detailed description of the embodiments of the present invention is made with reference to the accompanying drawings, so that the technical solution of the present invention can be more easily understood and grasped.

Example 1

Referring to fig. 1, 2, 3, 4, 5, the air valve includes a top cover 1, a bottom cover 2 and a suction piece 5, the top cover is a cylindrical body with an open bottom end, the bottom cover is disc-shaped, a first protruding portion 3 with a through hole 4 is arranged at the center of the upper surface, the through hole penetrates through the bottom cover, the top cover and the bottom cover are made of environment-friendly materials, for example, HDPE, an opening of the vent hole at the bottom of the bottom cover extends outwards to form a second protruding portion 41, a plurality of vent grooves 6 are arranged on the periphery of the columnar first protruding portion and the second protruding portion, the vent grooves extend upwards from the first protruding portion and the periphery of the second protruding portion to the opening of the through hole, the suction piece made of silica gel is a groove body, a third protruding portion 51 extends upwards from the groove, a fourth ring groove 52 is arranged on the periphery of the third protruding portion, the suction piece is buckled on the second protruding portion, and the third protruding portion is embedded in the through hole.

In another preferred embodiment, as shown in fig. 1, 2, and 4, the first annular groove 31 is formed at the top of the first protrusion, the through hole is located in the region surrounded by the first annular groove, the vent groove extends to the opening of the through hole along the first annular groove, meanwhile, the second annular groove 11 is formed in the middle of the top cover corresponding to the through hole, when the top cover is fastened to the bottom cover, the location of the through hole is located in the region surrounded by the second annular groove, and the region between the second annular groove and the first annular groove forms a buffer region, so that the impurities are effectively blocked.

Similarly, a third ring groove 32 is formed around the through hole at the top of the first protrusion.

It is of course also possible to connect the vent grooves outward of the periphery of the first protrusion to each other to form the fifth ring groove 33, as shown in fig. 2 and 5, to further reduce the weight.

In another preferred embodiment, as shown in fig. 1 and 3, the bottom of the bottom cover is provided with a receiving groove 21 corresponding to the through hole, the second protrusion is located in the receiving groove, and the suction piece is embedded in the receiving groove when being buckled on the second protrusion, so as to limit the collision and displacement of the article on the suction piece in the horizontal direction.

As shown in fig. 5, the air in the fresh-keeping bag enters the top cover through the air vent groove, and pushes up and displaces the third protrusion along the through hole, so that the air flows out from the gap between the third protrusion and the through hole and is discharged along the air vent groove on the peripheral side of the first protrusion.

As shown in FIG. 6, when the suction nozzle 7 is connected to the receiving groove, the silica gel sheet is suspended under the action of the air pressure of the nozzle, which is beneficial to quickly drying the air in the bag.
