Prevent dust from entering the sealing surface of the valve plate to improve the reliability of the sealing performance of the plastic bag.
该阀片 21为软质胶料， 中间凸起一圆锥头 211， 其同阀座上的锥孔紧密配合而形成可靠 的密封面。 该阀片 21设置于阀座 22和与其粘结的胶袋膜片 10之间； 抽气时， 气压可使阀片 圆锥头 211轻轻抬起， 让空气经空气通道 30被抽走， 抽气完成后， 则由于负压作用， 阀片圆 锥头 211又紧紧地贴合在阀座锥孔上。 The valve piece 21 is a soft rubber material, and a conical head 211 is protruded in the middle, which closely cooperates with the tapered hole on the valve seat to form a reliable sealing surface. The valve piece 21 is disposed between the valve seat 22 and the plastic bag diaphragm 10 bonded thereto; when pumping, the air pressure can gently lift the valve cone 211, and the air is pumped away through the air passage 30, pumping After the gas is completed, the valve is round due to the negative pressure. The cone 211 is tightly attached to the valve seat taper hole.
带有该抽气阀 20的胶袋袋口处设有一条密封拉链 40， 通过该密封拉链 40的开合可以进 行放取包装物品， 此结构使得用户可在不损坏胶袋的情况下， 循环使用和多次使用。  A sealing zipper 40 is provided at the mouth of the plastic bag with the suction valve 20, and the sealing zipper 40 can be opened and closed to allow the user to take out the packaged articles. This structure allows the user to circulate without damaging the plastic bag. Use and use multiple times.
本发明的真空保鲜密封袋可以循环或多次使用， 避免了浪费。 所述的阀座面凹槽同紧配 的阀盖形成狭窄的空气通道， 可过滤袋内空气， 从而避免灰尘进入阀片与阀座的密封表面； 阀片圆锥头结构更加确保了密封的可靠性。 本实用新型适用于家庭、 酒楼、 餐厅及户外旅游 等领域使用， 配合抽真空装置可对食品和贵重饰品等实行压縮及真空包装储存。  The vacuum fresh-keeping sealed bag of the present invention can be recycled or used multiple times, avoiding waste. The valve seat surface groove forms a narrow air passage with the tightly arranged valve cover, and can filter the air in the bag to prevent dust from entering the sealing surface of the valve plate and the valve seat; the valve cone conical structure ensures the sealing reliability. Sex. The utility model is suitable for use in the fields of family, restaurants, restaurants and outdoor tourism, and can be used for compression and vacuum packaging storage of foods and precious ornaments with a vacuum device.
以上所述， 仅是本发明的较佳实施例而已， 并非对本发明作任何形式上的限制， 故凡是 未脱离本发明技术方案内容， 依据本发明的技术实质对以上实施例所作的任何简单修改、 等 同变化与修饰,均仍属于本发明技术方案的范围内。  The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way. Therefore, any simple modifications made to the above embodiments in accordance with the technical spirit of the present invention without departing from the technical scope of the present invention. And equivalent changes and modifications are still within the scope of the technical solution of the present invention.
