Description

手动多用气泵
本实用新型是关于一种具有充气和抽气两种功能的便携式手动气泵。适用于给自行车、球类充气,给食物保鲜容器抽真空和拔罐等多种用途。
该技术领域的已有产品有手动打气泵,或手动抽气泵。
本实用新型的目的是提供一种手动气泵,既能用于充气又能用于抽气,成为一种双功能的多用途气泵。
本实用新型为实现上述目的的技术方案是一个气缸带两个单向阀;一端用于充气,另一端用于抽气。
上述技术方案,将手动打气泵和手动抽气泵合而为一,结构简单、小巧,使用方便,成本低廉。可根据需要,作充气或抽气使用。
下面结合附图和实施例对本实用新型作详细说明:
附图是本实用新型的结构示意图。
图中1.端盖2.端头3.4.单向阀5.密封环6.活塞7.缸筒8.活塞杆9.工作腔。
用于充气时,活塞杆(8)推入,工作腔(9)内的空气受压,封住单向阀(3),经单向阀(4),从端头(2)的气口向外排出压缩空气。回程时,外部的空气经端盖(1)的气口及单向阀(3)进入工作腔(9)。
用于抽气时,活塞杆(8)拉出,工作腔(9)的空气减压,单向阀(4)被封住,外部的空气由端盖(1)的气口,经单向阀(3)于由入腔(9)。回程时,腔(9)内空气经单向阀(4)、端头(2)气口排出。

Claims (1)

1.一种手动多用气泵,在缸筒(7)的一端设有端盖(1),与活塞(6)和活塞杆(8)在缸筒(7)中顺序排列,其特征是:端盖(1)中设有通气方向朝内的单向阀(3),活塞(6)中设有方向与单向阀(3)相同的单向阀(4),活塞杆(8)的一端设有端头(2)。
