[0024] Figure 4 Draws Figure 1 Schematic diagram of the installation of the foam shield shown. DETAILED DESCRIPTION

[0025] Please refer to Figures 1 to 4 The foam shield comprises a liquid pump 10 and a foam box 20. The liquid pump 10 is connected to the foam box 20. The foam box is provided with a liquid storage chamber 21, a mixing chamber 22, an input channel 23 and an output channel 24. The input channel 23 is connected to the liquid storage chamber 21 and the liquid inlet of the liquid pump 10. The output channel 24 is connected to the mixing chamber 22 and the liquid outlet of the liquid pump 10. The liquid in the liquid storage chamber 21 is transported to the mixing chamber 22 through the liquid pump 10. The foam box 20 is provided with a liquid adding port 25 and an exhaust hole 26 at the top of the liquid storage chamber 11. Liquid can be added to the liquid storage chamber 21 through the liquid adding port 25. The mixing chamber 22 is provided with a water inlet 27 and a water outlet 28. Water can enter the mixing chamber 22 from the water inlet 27. The water is mixed with the liquid in the mixing chamber and then discharged from the water outlet 28, that is, the water outlet discharges the foam liquid for foaming. It is understandable that it is not necessary to start the liquid pump 10 to add the liquid in the liquid storage chamber 21 to the mixing chamber 22 every time the water is drained from the water outlet 28. The concentration of the mixed water in the mixing chamber 22 can be determined. For example, if the liquid pump 10 draws a small amount of water from the liquid storage chamber 21 into the mixing chamber 22 each time, the liquid pump 10 will be started after the water outlet 28 drains about twice. If the liquid pump 10 draws a large amount of water from the liquid storage chamber 21 into the mixing chamber 22 each time, the water outlet 28 will need to drain about four times before starting the liquid pump 10.

[0026] Preferably, the water inlet 27 and the water outlet 28 are arranged at the top of the mixing chamber 22 , that is, the top of the foam box 20 .

[0027] Preferably, the foam box 20 comprises a box body 20-1 and a box cover 20-2, and the box cover 20-2 is connected to the box body 20-1 by welding. A liquid filling port 25, an exhaust hole 26, a water inlet 27 and a water outlet 28 are all arranged on the box cover 20-2.

[0028] Preferably, the box cover 20-2 is provided with a liquid inlet connection groove 232 and a liquid outlet connection groove 242, wherein the liquid inlet connection groove 232 connects the input channel 23 and the liquid storage chamber 21, and the liquid outlet connection groove 242 connects the output channel 24 and the mixing chamber 22, and further comprises a liquid extraction silicone tube 30, wherein the upper end of the liquid extraction silicone tube 30 is connected to the liquid inlet connection groove 232, and the lower end of the liquid extraction silicone tube 30 extends downward to the bottom of the liquid storage chamber 21. Therefore, under the drive of the liquid extraction pump 10, the liquid in the liquid storage chamber 21 enters the liquid inlet connection groove 232 along the liquid extraction silicone tube 30, and then enters the liquid extraction pump 10 through the input channel 23, enters the liquid outlet connection groove 242 after coming out of the output channel 24, and finally reaches the mixing chamber 22.

[0029] Preferably, a long groove 29 is provided on the upper surface of the box cover 20-2, and the liquid inlet connection groove 232 and the liquid outlet connection groove 242 are opened on the bottom wall of the long groove 29, and also includes a sealing strip 40 for covering the long groove, and the sealing strip is connected to the box cover by welding.

[0030] Preferably, a liquid-adding silicone tube 50 is further included, the upper end of which is connected to the liquid-adding port 25 , and the lower end of which extends downward to the bottom of the liquid storage chamber 21 .

[0031] Preferably, a one-way valve 70 is provided in the output channel 24 to prevent the water in the mixing chamber from flowing back.

[0032] Preferably, the bottom of the liquid storage chamber 21 and the mixing chamber 22 are both provided with a drain plug 80 to facilitate draining the liquid in the chamber during daily maintenance.

[0033] Preferably, the foam box 20 is provided with a notch at the bottom, the liquid pump 10 is installed at the notch, and the mixing chamber 22 is located above the notch.

[0034] Preferably, the device further comprises a cover shell 60 for covering the liquid suction pump 10 , and the cover shell 60 is buckled with the foam box 20 .

[0035] Preferably, the water discharged from the water outlet 28 is connected to a foamer to increase the foaming effect. Further preferably, the foamer is a Venturi foamer.

[0036] Please refer to Figure 4 The foam shield is installed under the back cover of the toilet, with a modular setting, which saves space and simplifies the structure under the back cover of the toilet.

[0037] The above description is only a preferred embodiment of the present invention, and therefore cannot be used to limit the scope of implementation of the present invention. That is, equivalent changes and modifications made according to the patent scope of the present invention and the contents of the specification should still fall within the scope covered by the present invention.
