    • A manually operated liquid foaming dispenser is attached to the top of a container of liquid and is manually reciprocated to dispense the liquid from the container as a foam. The dispenser includes a liquid pump chamber and an air pump chamber that respectively pump liquid and air under pressure to a discharge passage of the pump where the liquid and air are mixed, generating the foam dispensed from the dispenser. The air pump chamber has a tube valve controlling the discharge of air from the air pump to the discharge passage, and the air pump chamber is charged with air by opening the air pump chamber to the exterior environment of the dispenser.
    • 手动操作的液体发泡分配器附着在液体容器的顶部,并且被人工往复运动以便将泡沫从容器中分配出来。 分配器包括液体泵室和空气泵室,其分别将液体和空气在压力下泵送到泵的排出通道,在该排出通道中混合有液体和空气,产生从分配器分配的泡沫。 空气泵室具有管阀,其控制从空气泵排出到排出通道的空气,并且通过将空气泵室打开到分配器的外部环境来为空气泵室充满空气。

    • The present invention pertains to the construction of a manually operated trigger sprayer in which the sprayer housing has a reduced diameter dimension liquid discharge passage to increase the velocity of liquid flow through the liquid discharge passage, and in which the nozzle assembly has a novel configuration that securely attaches the nozzle assembly to the sprayer housing to prevent the increased velocity of liquid flow through the sprayer housing liquid discharge passage from dislodging the nozzle assembly from the sprayer housing. The novel construction of the sprayer housing and the nozzle assembly includes a resilient crossbar provided on the sprayer housing that crosses over the liquid discharge passage and a pair of resilient flanges on the nozzle assembly that engage over opposite sides of the sprayer assembly crossbar and securely attaching the nozzle assembly to the sprayer housing.
    • 本发明涉及一种手动触发式喷雾器的结构,其中喷雾器壳体具有减小直径尺寸的液体排出通道,以增加通过液体排出通道的液体流速,并且其中喷嘴组件具有新颖的构造, 将喷嘴组件牢固地附接到喷雾器壳体,以防止液体流过喷雾器壳体液体排出通道的速度增加,从而将喷嘴组件从喷雾器壳体移出。 喷雾器壳体和喷嘴组件的新颖结构包括设置在喷雾器壳体上的弹性横杆,其横过液体排放通道和喷嘴组件上的一对弹性凸缘,其接合在喷雾器组件横杆的相对侧上并牢固地附接 喷嘴组件到喷雾器壳体。
