Vacuum preservation box air pumping valve

Abstract

The invention discloses a vacuum preservation box air pumping valve, which is arranged on a preservation box and comprises a valve body, an air bleeder, a valve seat and a valve cover, wherein the air bleeder and the valve seat are nested inside the valve body and are connected through screw threads, the valve cover is screwed and connected with the top end of the valve body, a reverse T-shaped pull rod is arranged on the air bleeder, the valve cover is sheathed on a pull rod, the bottom of the pull rod is movably matched with the inner wall of the air discharge valve embedded with a valve core, an open hole used for air circulation is arranged on the pull rod, and the top end of the pull rod passes through the valve cover and is connected onto the press cover and the handle. The vacuum preservation box air pumping valve has the advantages that the structure is simple, the operation is convenient, the air pumping process can be realized through lifting the handle to drive the pull rod, the air release can be realized through directly screwing the valve cover, the time and the labor are saved, the air pumping speed is high, the vacuum preservation box air pumping valve is suitable for being bought by ordinary customers, and the popularization performance is high.

Description

technical field [0001] The invention relates to a valve, in particular to an air extraction valve applied to a vacuum fresh-keeping box. Background technique [0002] The vacuum storage box uses vacuum to discharge the air in the box, so that the food in the storage box can achieve the effect of moisture-proof and mildew-proof. However, the manual exhaust valves currently on the market that are used in vacuum crispers are large in size and occupy container space, and the silicone seat of the exhaust valve is easy to fall off and age. Contents of the invention [0003] The object of the present invention is to overcome the disadvantages of the above-mentioned prior art, and provide a vacuum fresh-keeping box exhaust valve that can be integrated with a fresh-keeping box and is convenient and quick to use. [0004] A vacuum fresh-keeping box air extraction valve is arranged on the fresh-keeping box, including a valve body, an air release valve and a valve seat nested in the ...
