  • FIG. 3 is a sectional view of a piston rod moving upward in an operation in accordance with the present invention.
  • FIG. 4 is a sectional view of a piston rod moving downward in an operation in accordance with the present invention.
  • the foam soap dispenser is generally installed at a position adjacent to a hand-washing sink, and comprises a pump 1 , a piston rod 2 , a valve seat 3 sheathed on the top of piston rod 2 , a feed pipe 4 coupled to the bottom of the pump 1 , a liquid soap bottle coupled to the bottom of the feed pipe 4 for storing liquid soap, a feed check valve 6 and a discharge check valve 5 installed in the pump for feeding foam soap in a single direction, and a restoring spring 7 installed and acted between the feed check valve 6 and the discharge check valve 5 , wherein the discharge check valve 5 divides the pump 1 into a discharge chamber 11 and an air-liquid mixing chamber 12 , and after the foam soap is mixed in the discharge chamber 11 , the foam soap passes through the discharge check valve and enters into a chamber, and an air-liquid mixing chamber 12 is formed between the feed check valve 6 and the discharge check valve 5 and communicate
  • a bump 93 is formed at a base of the screw sleeve 9 , and a buckle 131 is installed at an end of the air-intake pipe 13 and corresponding to the bump 93 , and the screw sleeve 9 is buckled to an end of the air-intake pipe 13 .
  • the discharge check valve 5 includes a first rubber base 51 and a first blocking edge 52 surrounding the periphery of the first rubber base 51 and having a cross-section substantially being a V-shaped opening
  • the feed check valve 6 includes a second rubber base 61 and a second blocking edge 62 surrounding the second rubber base 61 and having a cross-section substantially being a V-shaped opening
  • the V-shaped openings of the first and second blocking edges 52 , 62 are aligned in the same direction.
  • the air-intake check valve 8 includes a third rubber base 81 and a third blocking edge 82 surrounding the periphery of the third rubber base 81 and having a cross-section substantially being a V-shaped opening. Therefore, the feed chamber is at a sealed status when the soap dispenser is not in use, and the space of the feed check valve, the discharge check valve and the air-intake check valve 8 communicated with the air-intake hole is in a sealed status.
  • the piston rod 2 has a through hole 21 for delivering a foam soap, and the piston rod 2 further has a radial hole 22 , and the rubber base of the discharge check valve has a protruded embedding portion 53 for sealing the through hole 21 of the piston rod 2 , and an end of the embedding portion seals the through hole 21 , and the discharge chamber 11 is communicated with the through hole 21 through the radial hole 22 .
  • the piston rod 2 is pressed down to compress the discharge chamber 11 , so that the first blocking edge 52 of the discharge check valve 5 is retracted by the discharge chamber 11 that is compressed by pressure, and the mixed foam soap is sent upwardly.
  • the discharge chamber 11 compressed by pressure drives the second blocking edge 62 of the feed check valve 6 and the third blocking edge 82 of the air-intake check valve 8 to expand outwardly to seal the air-liquid mixing chamber 12 .
  • a through hole 83 of the screw rod 10 formed at the bottom of the air-intake check valve 8 and the screw rod 10 have an interference fit, and the screw sleeve 9 has an inner thread formed therein and corresponding to the screw rod, and an end of the screw rod proximate to the air-intake hole is in a conical shape.

Since the sealed space of the discharge check valve 5 , the feed check valve 6 , and the air-intake check valve 8 communicated with the air-intake hole is constant, therefore an increase of air intake will cause a decrease of the amount of incoming liquid soap, or a decrease of air intake will cause an increase of the amount of incoming liquid soap to maintain a balance of pressure, so as to achieve the effect of adjusting the mixture ratio of air to liquid soap.
  • the valve seat 3 is sheathed on the top of the piston rod 2 , and the piston rod 2 is movably installed in the valve seat 3 , and the piston rod and the valve seat 3 further include a first sealing ring 231 installed therein, and a second sealing ring 131 is installed between the valve seat 3 and the pump 1 to improve the sealability of the chamber.
  • the present invention can adjust the air amount of intake air of the foam soap dispenser as required, and prevent the situations of having insufficient liquid soap or wasting the liquid soap.
