    • A dispenser can automatically dispense chemical from an aerosol container at predetermined intervals without the use of electric power. A diaphragm at least partially defines an accumulation chamber that receives chemical from the can during an accumulation phase. Once the internal pressure of the accumulation chamber reaches a predetermined threshold, the diaphragm moves, carrying with it valving that controls a spray burst. The diaphragm assumes its original position when the pressure within the accumulation chamber falls below a threshold pressure. A barrier prevents the aerosol container from resupplying the accumulation chamber at a high rate during the spray phase, preferably due to a porous gasket disposed in a passageway linking the dispenser to the aerosol container.
    • 分配器可以在不使用电力的情况下以预定间隔自动地从气溶胶容器分配化学品。 隔膜至少部分地限定在积聚阶段期间从罐接收化学物质的积聚室。 一旦积聚室的内部压力达到预定的阈值,隔膜就会移动,并带有控制喷雾的阀门。 当积聚室内的压力低于阈值压力时,隔膜承受其原始位置。 屏障防止气雾剂容器在喷雾阶段期间以高速率重新供应积聚室,优选地由于设置在将分配器连接到气溶胶容器的通道中的多孔垫片。

    • An actuator assembly is disclosed which can dispense chemicals, such as insect control ingredients, from an aerosol container. The actuator assembly is mountable to the aerosol container and includes a burstable barrier and an extrudable (e.g. paste) plug. Upon initial activation, the pressure from inside of the container presses the burstable barrier which in turn presses the paste plug to cause at least a portion of the plug to move to a position where it is visible and provides a cue that a delay period has started. The device can be manually activated, but is designed so that thereafter it does not need to be manually held open. The user has time to leave the room before spraying begins, and does not need to be present in the room before spraying has finished.
    • 公开了一种致动器组件,其可以从气溶胶容器分配诸如昆虫控制成分的化学物质。 致动器组件可安装到气溶胶容器并且包括可爆破屏障和可挤出(例如糊状)塞子。 在初始激活时,来自容器内部的压力按压可爆破屏障,该阻挡层又压入糊塞,使塞子的至少一部分移动到可见的位置,并提供延迟时间已经开始的提示 。 该设备可以手动启动,但是设计使其不需要手动打开。 用户在喷涂开始前有时间离开房间,喷涂完成前不需要在房间内。
