Automatic liquid dispensing mechanism

Abstract

An automatic liquid dispensing mechanism includes a planet device and a transmitting hose. The planet device is a plate with a number of rollers provided on a surface thereof such that the rollers can rotate on the surface of the plate. The hose in the form of an arc is engaged in-between the inner rim of the hosing and the outer surface of the rollers. The axis of a driving motor passes through the plate and a side of the housing, and then contacts with the surface of the rollers, thereby the rotation of the axis of the driving motor drives the rollers and the plate to rotate. And then the rollers push the liquid stored in the hose and make it transmitted from the storage tank to the user's end.

1 . A liquid dispensing mechanism is directly driven by a motor and includes a planet device, a hose and a housing, wherein: 
 the planet device provided on a bottom of the housing includes a rotating plate, from the surface of which a number of axles are extruded, and each axle is sheathed by a roller;    the hose, being a transmitting carrier, is in the form of an arc provided in-between the inner rim of the housing and the outer surface of the rollers;    extrusions are provided on the hose and engaged in the opposite grooves of the housing; and    the outer surface of each roller contacted with the axis of the motor is driven to rotate by the motor; the plate of the planet device pushes the hose circularly, thereby transmitting the liquid.    
   
   
       2 . A liquid dispensing mechanism according to  claim 1 , wherein the axis of the motor passes through the plate center of the planet device.  
   
   
       3 . A liquid dispensing mechanism according to  claim 1 , wherein the rollers of the planet device do not contact with each other, but contact with the axis of the motor.
