Abstract: A gas pump is composed of a gas suction member and a gas exhaust member. The gas suction member includes a gasbag having a hollow retractable portion being drivable by a motor for oppression or expansion, an intake valve allowing the air to pass therethrough when the hollow retractable portion is oppressed, and a flexible tube having two crosscuts, by which the flexible tube is divided into two vent valvular pieces. Each of the vent valvular pieces has a reinforcing strip formed on an internal wall thereof for forcing each of the vent valvular pieces to seal the exhaust passage. The gas exhaust member is mounted to the gasbag and includes a venthole and a guide slot. The venthole can receive the flexible tube therein. The guide slot communicates the hollow retractable portion and the intake valve for guiding the air into the hollow retractable portion.

Abstract translation: 气泵由吸气构件和排气构件构成。 吸气构件包括具有中空的可缩回部分的气囊，其可被用于压缩或膨胀的马达驱动，当中空可缩回部分被压缩时允许空气通过的进气门;以及具有两个横截面的柔性管， 柔性管分为两个排气阀瓣。 每个排气瓣件具有形成在其内壁上的加强条，用于迫使每个通风阀瓣密封排气通道。 气体排出构件安装在气囊上并且包括通气孔和引导槽。 通气孔可以在其中容纳柔性管。 引导槽连通中空的可缩回部分和进气门，以将空气引导到中空的可缩回部分中。
