    • A battery operated, handheld fluid dispenser comprises a supply container having a body portion and a narrow neck extending upwardly therefrom. A pump and discharge unit is mounted on the upper end of the neck and comprises a pump diaphragm and pump chamber for pumping liquid from the container to a discharge nozzle. A battery powered pump drive unit is mounted on the container and comprises an electric motor having an output shaft coupled with the pump diaphragm through a cam and cam follower arrangement to displace the diaphragm through a pump stroke when the motor is energized. The cam is rotatably driven by the motor, and the cam follower is attached to the diaphragm, whereby rotation of said cam axially displaces the diaphragm, and the cam and cam follower have interengaging dual cam faces for balancing lateral forces therebetween during rotation of said cam relative to said cam follower.
    • 电池操作的手持流体分配器包括具有主体部分和从其向上延伸的窄颈部的供应容器。 泵和排放单元安装在颈部的上端,并且包括用于将液体从容器泵送到排出喷嘴的泵隔膜和泵室。 电池供电的泵驱动单元安装在容器上,并且包括电动机,其具有通过凸轮和凸轮从动装置与泵隔膜联接的输出轴,以在电动机通电时通过泵行程移动隔膜。 凸轮由电动机可旋转地驱动,并且凸轮从动件附接到隔膜,由此所述凸轮的旋转轴向地使隔膜移动,并且凸轮和凸轮从动件具有相互接合的双凸轮面,用于在所述凸轮的旋转期间平衡其间的横向力 相对于所述凸轮从动件。

    • The present invention relates to a portable sprayer for applying a diluted product to a surface to be treated. The sprayer includes a housing including an inlet for supplying pressurized water to the sprayer, a first water only outlet, and a second diluted product only outlet. A mixing chamber is located within the housing. The mixing chamber is dimensioned to securely hold the product and is in fluid communication with the second outlet. A first flow passage extends through the housing. The first flow passage is in selective fluid communication with the inlet and the first outlet. A second flow passage extends through the housing. The second flow passage is in selective fluid communication with the first flow passage and the mixing chamber. A wall of the second flow passage is configured to direct the pressurized water flowing through the second flow passage into the mixing chamber to evenly dissolve the product and provide a generally consistent product to water ratio.
    • 本发明涉及一种用于将稀释产物施加到待处理表面的便携式喷雾器。 喷雾器包括壳体,该壳体包括用于向喷雾器供应加压水的入口,仅第一水出口和仅第二稀释产物出口。 混合室位于壳体内。 混合室的尺寸设计成可靠地保持产品并与第二出口流体连通。 第一流动通道延伸穿过壳体。 第一流道与入口和第一出口选择性地流体连通。 第二流动通道延伸穿过壳体。 第二流动通道与第一流动通道和混合室选择性地流体连通。 第二流动通道的壁被构造成将流过第二流动通道的加压水引导到混合室中以均匀地溶解产品并提供大致一致的产品与水的比例。

    • An apparatus for brewing coffee or the like with microwave energy comprising a receptacle for receiving a brewed beverage, and a generally funnel-shaped reservoir having an open upper end, a closed lower end and an aperture near the closed lower end. A flange extends outwardly from the reservoir and is operable to position the apparatus over the receptacle wherein the aperture is disposed over the receptacle. A valve is provided to control flow of liquid from the reservoir and is operable to allow flow upon the existence of a predetermined condition in the reservoir.
    • 一种用于用微波能冲煮咖啡等的装置,包括用于接收冲泡饮料的容器,以及一个大致漏斗形的储存器,其具有开口的上端,封闭的下端和靠近闭合的下端的孔。 凸缘从储存器向外延伸并且可操作以将装置定位在容器上,其中孔设置在容器上方。 提供阀以控制来自储存器的液体的流动,并且可操作以允许在储存器中存在预定条件时流动。
