ABSTRACT:
An improved extruding mechanism for auto soap dispenser which comprises, a soap dispenser equipped with an under outlet, a sleeve positioned underneath the dispenser, an output port locating at the bottom of the sleeve, and there is a valve seat which is installed inside the sleeve and therein sliding up and down, more particularly the valve seat consists of a disk block which includes several circulated holes and a mandrel, therefrom the mandrel on the top of valve seat is inserted with a spring and moreover the mandrel at the bottom of valve seat is equipped with a diaphragm; and there is a side tube positioned on the flank of sleeve and thereon connected to an extruding hose, and a link that pivoted at external end of the extruding hose is also pivoted by a motor driven eccentric wheel at its opposite end; according to the structure described above, the elastically reciprocating motion on the extruding hose which caused by motor driven eccentric wheel will put the squeeze on valve seat and then have it slid up and down and thus result in a corresponding motion to extrude the liquid soap out of the dispenser accordingly, by way of having an enclosed extruding hose so that the liquid soap is prevented from contacting air and so as not to dry out quickly, in addition it will force the diaphragm to cover closely onto the circulated holes locating in the valve seat and meanwhile the diaphragm would be able to be pressed down by spring force and hence to impact onto the outlet port that positioned on the sleeve and in this way preventing the liquid soap from leaking.
