Description

[根据细则37.2由ISA制定的发明名称]　一种充气泵外壳 技术领域
本发明涉及充气泵技术领域，具体为一种新型充气泵外壳。
背景技术
充气泵又叫打气机、打气泵、充气泵，是通过马达的运转来工作，当马达运转抽气时，连通器的阀门被大气的气压冲开，气体进入气筒，而向物品中打气时，阀门又被气筒内的气压关闭，气体就进入了物体中完成充气。
现市面上的充气泵外壳大多数安装在充气泵上使用时功能性较为单一，当充气泵运行时，气体穿过充气泵外壳的气孔时容易出现较为严重的阻力，气体在穿过气孔的过程中会导致气体出现不同程度的损耗，从而也就导致了充气和吸气时效率较低的情况，同时多数充气泵外壳的外部附件都是附加式的结构，在使用的过程中容易出现占用空间过多的情况，无法方便的将电线等物体收纳好，应用时存在一定的局限性。
