用于个人护理装置的离散量流体分配系统
Discrete-amount fluid-dispensing system for a personal care device
US-8425133-B2用于个人护理器具如电动牙刷的流体分配系统。
专利摘要
该流体分配系统用于个人护理器具，例如电动牙刷。分配系统包括一条离散的含流体小袋带、一个可压缩密封件和一个用于刺穿小袋的中空针头，中空针头通过连接管线连接到诸如刷头的工作件。致动组件包括活塞，该活塞将连续的小袋推向密封件，首先将小袋密封到密封件上。进一步的压力导致密封件压缩和针头刺穿小袋，流体在活塞压力下从小袋进入中空针头，然后进入连接管线以输送到工作件。
Original abstractThe fluid-dispensing system is used in a personal care appliance, such as a power toothbrush. The dispensing system includes a strip of discrete, fluid-containing packets, a compressible sealing member and a hollow needle for puncturing the packets, the hollow needle being connected to a workpiece such as a brushhead via a connecting line. An actuation assembly includes a piston which moves successive packets against the sealing member, initially sealing the packet thereto. Further pressure results in compression of the sealing member and puncturing of the packet by the needle, with fluid being forced by piston pressure from the packet into the hollow needle and then to the connecting line for delivery to the workpiece.
