Structure for controlling soap discharging quantity of soap dispensing apparatus

Abstract

A structure for controlling soap discharging quantity of soap dispensing apparatus includes a connector coupling with a liquid soap container by screwing that has a bottom housed in a sleeve. The sleeve has a pump housing on one side formed by an elastic pressure bulb. The sleeve has a discharge opening on the bottom and houses axially an upper valve and a lower valve that form a valve chamber therebetween. The tubular wall of the sleeve on the pump housing on an upper end of the lower valve has a hole. The tubular wall of the sleeve on the upper end of the upper valve has an upper hole. The upper hole can disperse pressure entering the valve chamber to make outlet of the valve chamber smaller thereby to reduce output quantity of the liquid soap. An action passage of vacuum suction force can also be formed to suck the liquid soap held on the bottom of the soap container into the valve chamber.

1 . A structure for controlling soap discharging quantity of soap dispensing apparatus, comprising a connector coupling with a liquid soap container and a sleeve which has a top end to house the bottom of the connector; the sleeve having one side coupled with an elastic pressure bulb to form a pump housing and housing axially an upper valve and a lower valve that form a valve chamber therebetween, the tubular wall of the sleeve between the pump housing and the valve chamber having a hole on an upper end of the upper valve, the valve chamber having an outlet which is opened through the hole when the pump housing receives a pressure to allow liquid soap to be discharged through a discharge opening on the bottom of the sleeve; the valve chamber having an inlet to receive the liquid soap into the valve chamber;
 wherein the tubule wall of the sleeve has an upper hole located above the hole and the upper valve to reduce output quantity of the liquid soap.   
   
   
       2 . The structure for controlling soap discharging quantity of  claim 1 , wherein the hole is a pair of slots symmetrical on a left side and a right side. 
   
   
       3 . The structure for controlling soap discharging quantity of  claim 1 , wherein the hole is formed in a desired shape and arranged in a juxtaposed manner. 
   
   
       4 . The structure for controlling soap discharging quantity of  claim 1 , wherein the upper hole is a round aperture. 
   
   
       5 . The structure for controlling soap discharging quantity of  claim 1 , wherein the upper hole is a single aperture formed in a desired shape. 
   
   
       6 . The structure for controlling soap discharging quantity of  claim 1 , wherein the upper hole includes a plurality of apertures arranged in a juxtaposed manner.
