    • A short term underwater breathing device including one or more housings containing a compressor powered by a battery for pumping air from an air intake valve through an air filter and dryer into a storage reservoir. The user draws air from the storage reservoir through a demand regulator. An electronic controller regulates the compressor, controls the opening and closing of the air intake valve, and monitors the air storage reservoir pressure. In a preferred embodiment the compressor, the battery, the air filter and dryer, and the controller are contained within a water tight compartment of a housing, which housing is preferably worn by the user. When the user is on the surface, the air intake valve opens and the battery provides power to the air compressor which draws the air through the filter and the dryer into the air storage reservoir. When submerged, the air intake valve closes, the compressor stops, and the user breaths the air from the storage reservoir through the regulator. The reservoir can provide several minutes of air to the user while under water.
    • 一种短期的水下呼吸装置,包括一个或多个壳体,其包含由电池供电的压缩机,用于将空气从进气阀通过空气过滤器和干燥器抽吸到储存容器中。 用户通过需求调节器从储存容器吸取空气。 电子控制器调节压缩机,控制进气阀的打开和关闭,并监测储气罐的压力。 在优选实施例中,压缩机,电池,空气过滤器和干燥器以及控制器被容纳在壳体的防水舱内,该壳体优选地被使用者佩戴。 当用户在表面上时,进气阀打开,电池向空气压缩机提供动力,空气压缩机将空气通过过滤器和干衣机吸入空气储存器。 当被淹没时,进气阀关闭,压缩机停止,用户通过调节器从储存容器呼吸空气。 储水池在水下可以向使用者提供几分钟的空气。
