It is corresponding with aspirating hole size and be coaxially disposed；The cylindrical and circular groove of the annular protrusion is correspondingly arranged, the upper lid
Inner peripheral wall is provided with buckle, and the outer circle wall of the annular protrusion is provided with neck corresponding with buckle.The upper lid and bottom
The caulking groove of magnet piece can be installed by being equipped with seat, and caulking groove is correspondingly arranged at the front end of buckle and neck respectively, and the magnet piece is matched somebody with somebody
Close buckle and neck and closely fasten upper lid and bottom seat.
By using above-mentioned technical proposal, upper lid and bottom seat is articulated and connected, by buckle and neck coordinate in fastening lid and
Base, fastening structure is simple, easy to operate, can rapidly cover and cover after gas is exhausted, by setting magnet piece, can make button
Close even closer, the gap after lid fastens with base in reduction.
The utility model is further arranged to, and the upper surface of the annular protrusion is provided with O-ring seal.
By using above-mentioned technical proposal, lid and annular protrusion contact can be made even closer, it is close so as to strengthen fastening
Seal effect.
The utility model is further arranged to, and the valve plug that can strengthen sealing effectiveness is provided with the upper lid.
The utility model is further arranged to, and the valve plug uses etch-proof rubber stopper.
By using above-mentioned technical proposal, valve plug is set further to strengthen the air-tightness after fastening, and use anti-corrosion
The rubber stopper of erosion, avoid corroding during valve plug long-time use and influenceing the quality of rice in rice bag.
The utility model is further arranged to, and the outer circle wall of the upper lid is provided with the projection of outwardly convex.
By using above-mentioned technical proposal, projection is set on the outer circle wall of upper lid, can be convenient to grip when opening,
Covered so as to more easily and effectively open.
