Abstract

A reservoir dispenser for a bidet washing apparatus includes a housing unit having at least one chamber, wherein the at least one chamber is capable of holding a liquid wash solution; a water inlet, a connecting tube, and a water outlet, wherein the water inlet, connecting tube and water outlet are in fluid communication, wherein the connecting tube is located between the water inlet and the water outlet, wherein the connecting tube includes a choke, and wherein the water inlet, connecting tube, and the water outlet are connectable to the housing unit; and a suction tube located between and in fluid communication with the at least one chamber and the choke.

Claims (73)

2. The reservoir dispenser of claim 1 , wherein the connecting tube is a linear connecting tube located between the water inlet and the water outlet.

3. The reservoir dispenser of claim 1 , wherein the connecting tube is a non-linear connecting tube located between the water inlet and the water outlet.

4. The reservoir dispenser of claim 3 , wherein the connecting tube is a circular connecting tube located between the water inlet and the water outlet.

5. The reservoir dispenser of claim 1 , wherein the suction tube is vertically inclined or horizontally inclined relative to the choke.

6. The reservoir dispenser of claim 1 , wherein a ratio of a constriction diameter of the choke to a general diameter of the connecting tube is from about 0.15 to about 0.70.

7. The reservoir dispenser of claim 1 , wherein a length, and/or a constriction angle (α), and/or a diffusion angle (β) of the choke can be modified to adjust how much reduced pressure is achieved in the choke.

8. The reservoir dispenser of claim 1 , wherein when water flows through the choke, a resulting reduced pressure in the choke causes a liquid wash solution present in the at least one chamber to be pulled into the choke through the suction tube.

9. A reservoir dispenser for a bidet washing apparatus, comprising:

a housing unit having a first chamber and a second chamber, wherein the first chamber is capable of holding a liquid wash solution separate from the second chamber;

a lid attachable to the first chamber;

an activator, wherein the activator includes the lid and the first chamber;

a water inlet, a connecting tube, and a water outlet, wherein the water inlet, connecting tube and water outlet are in fluid communication, wherein the connecting tube is located between the water inlet and the water outlet, wherein the connecting tube includes a choke, and wherein the water inlet, connecting tube, and the water outlet are connectable to the housing unit; and

a check valve located between the first chamber and the choke; and

a suction tube located between the check valve and the choke.

10. The reservoir dispenser of claim 9 , wherein the suction tube is vertically inclined relative to the choke.

11. The reservoir dispenser of claim 9 , wherein the second chamber includes a piston, a spring, and a cylinder.

12. The reservoir dispenser of claim 11 , wherein engaging or disengaging the activator causes the piston to go into or out of the cylinder and compresses or decompresses the spring, respectively.

13. The reservoir dispenser of claim 9 , wherein the check valve is a spring-loaded check valve, a ball and seat check valve, a diaphragm check valve, an umbrella check valve, or a duckbill check valve.

14. The reservoir dispenser of claim 9 , wherein the check valve includes:

a check valve body;

a T-bar shaped check valve disc, wherein the disc includes a proximal pole end and a distal bar end; and

a check valve spring.

15. The reservoir dispenser of claim 14 , further comprising at least one post located below the distal bar end of the T-bar shaped check valve disc.

16. The reservoir dispenser of claim 15 , wherein the proximal pole end of the disc closes off the first chamber from the check valve when the activator is disengaged, and wherein the distal bar end of the disc engages with the at least one post and the proximal pole end of the disc opens the first chamber to check valve and suction tube when the activator is engaged.

17. The reservoir dispenser of claim 9 , wherein engaging the activator allows transfer of the liquid wash solution from the first chamber through the check valve to the suction tube and choke.

18. The reservoir dispenser of claim 9 , wherein disengaging the activator blocks transfer of the liquid wash solution from the first chamber to the check valve, suction tube and choke.

19. The reservoir dispenser of claim 9 , wherein a ratio of a constriction diameter of the choke to a general diameter of the connecting tube is from about 0.15 to about 0.70.

20. The reservoir dispenser of claim 9 , wherein a length, and/or a constriction angle (α), and/or a diffusion angle (β) of the choke can be modified to adjust how much reduced pressure is achieved in the choke.

21. A reservoir dispenser for a bidet washing apparatus, comprising:

at least one chamber capable of holding a liquid wash solution;

a lid attachable to the at least one chamber;

an activator, wherein the activator includes a hollow closed ended upper tube, a hollow open ended lower tube that extends into the at least one chamber, and an outlet tube;

a pump chamber, wherein the pump chamber connects the hollow closed ended upper tube and the hollow open ended lower tube;

a housing unit, wherein the outlet tube is connectable to the housing unit;

a water inlet, a connecting tube, and a water outlet, wherein the water inlet, connecting tube and water outlet are in fluid communication, wherein the connecting tube is located between the water inlet and the water outlet, wherein the connecting tube includes a choke, and wherein the water inlet, connecting tube, and the water outlet are connectable to the housing unit; and

a check valve located in the housing unit between the outlet tube and the choke; and

a suction tube located between the check valve and the choke.

22. The reservoir dispenser of claim 21 , wherein the pump chamber includes a spring and a ball located between the hollow closed ended upper tube and the hollow open ended lower tube, respectively.

23. The reservoir dispenser of claim 21 , wherein the check valve includes:

a check valve body;

a check valve disc; and
