Abstract

本实用新型由在具有双向进气的打气筒筒体尾部加有设一抽气嘴2而成,具有双向进气的筒体1的两端设有进气阀8,活塞杆3又是出气管,活塞杆3的一端联接活塞7,活塞杆3的另一端连接打气嘴5,抽气嘴2与筒体1可以固定联接,也可以插拔式联接或螺丝联接。本实用新型具有打气和抽真空两种功能,结构简单而且使用方便。

Description

打气、抽真空两用泵
本实用新型涉及一种打气筒。
现有的一种打气筒，如图2所示，由筒体1、活塞7、活塞杆3及手把4等构成，筒体1的两端设有进气阀8，活塞杆3又为出气管，当使活塞7在筒体内往复运动时，气筒内一端形成负压，外界空气通过气阀8进入气筒内，而另一端气体受压缩，受压缩的气体进入活塞杆3内的气管，使气体从活塞杆3的另一端打气嘴5排出。这种打气筒的最大特点是结构简单和具有双向进气功能。
本实用新型的目的是改进上述打气筒，使其具有抽真空的功能。
本实用新型是在上述打气筒的筒体尾部加设一抽气嘴来实现的。
图1为本实用新型的结构示意图。
如图1所示，本实用新型由在具有双向进气的打气筒筒体尾部加设一抽气嘴2而成。这里所述的具有双向进气的打气筒是由筒体1、活塞7、活塞杆3、手把4和打气嘴5构成，筒体1的两端设有进气阀8，活塞杆3又是出气管，手把4安装在活塞杆3上，活塞杆3的一端联接活塞7，活塞7上设有活塞环6，活塞杆3的另一端连接打气嘴5。抽气嘴2设在筒体1的尾部，抽气嘴2与筒体1可以固定联接，也可以插拔式联接或螺丝联接。
使用时，使活塞7在筒体1内往复运动时，气筒1内活塞7的一端形成负压，外界空气通过气阀8进入气筒1内，而活塞6的另一端气体受压缩，受压缩的气体通过活塞环6处的进气孔进入活塞杆3内的气管，使气体从活塞杆3的另一端经打气嘴5喷出，而当活塞7的运动使气筒1尾部(右边)的进气阀8打开进气时，外界空气从抽气嘴2进入筒体内，这时，如果将抽气嘴2靠近要抽气部位，则可实现抽真空功能。
本实用新型具有打气和抽真空两种功能，结构简单而且使用方便。
