[0047] The foaming device of the utility model is applied to a toilet, and the working principle is as follows:

[0048] Liquid adding: the common foaming liquid (i.e. detergent, hand sanitizer, etc.) is poured into the liquid storage cavity 11 of the box body 1 from the liquid adding port 13. Since the common foaming liquid has high viscosity, the air pump 6 needs to be started to pump air out of the liquid storage cavity 11, so as to accelerate the flow of the common foaming liquid into the liquid storage cavity 11. At this time, the three-way module 7 is in working state, the movable core 73 of the three-way module 7 is sucked up and blocks the communication port 751, so that the negative pressure is fully applied to the liquid storage cavity 11. When the pouring is completed, the air pump 6 stops pumping air out of the liquid storage cavity 11, and the three-way module 7 resets the movable core 73 through the spring 74 to open the communication port 751, so that the three-way module 7 returns to the initial state. In the initial state, the first air port 711 and the second air port 721 of the three-way module 7 are in communication with each other, so that the liquid storage cavity 11 is in communication with the outside atmosphere, and the special foaming agent can be directly poured without using the air pump 6 to pump negative pressure.

[0049] Liquid mixing: the liquid pump 2 extracts an appropriate amount of foaming raw material from the liquid storage cavity 11 of the box body 1 into the primary dissolution chamber 35, and the water pump 4 pumps water into the water inlet chamber 34 of the dissolution cavity (there is also a route of water into the dilution cavity 12 of the box body 1). The water entering the water inlet chamber 34 is injected into the primary dissolution chamber 35 through various water passing holes 322 to form turbulence and vortex, impacting and dispersing the foaming liquid in the primary dissolution chamber 35, so that the foaming raw material is preliminarily dissolved in the primary dissolution chamber 35 and further dissolved in the secondary dissolution chamber 36 through the first communication port. The final water pressure drives the fully dissolved foaming liquid into the dilution cavity 12 of the box body 1 to mix and dilute with another route of water provided by the water pump 4.

[0050] Foaming: the diluted foaming liquid is driven by the water pressure of the water pump 4 to the foaming module 8, and the foaming liquid enters the cavity from the third liquid inlet 81 of the foaming module 8, and the diameter of the third liquid inlet 81 suddenly changes during entering the cavity to increase the kinetic energy of the liquid. At the same time, the air blown by the air pump 6 enters the cavity of the foaming module 8, and the air and the foaming liquid mix to produce a large number of bubbles with strong kinetic energy. The air blown by the air pump 6 comes from the air entering the liquid storage cavity 11 through the liquid adding port 13. Since the liquid adding port 13 leads to the outside at this time, the liquid storage cavity 11 is not in a sealed state, so the air pump 6 will not pump the foaming raw liquid in the liquid storage cavity 11 away when pumping air. The bubble water becomes more delicate foam particles after passing through the 2 layers of fine mesh inside the foaming module 8, and the foam particles are divided by the foam spraying pipe 9. Most of the foam particles are sprayed out through the main foam outlet with a smaller diameter, and a small part of the foam particles are sprayed out through the auxiliary foam outlet with a larger diameter. The main foam outlet rotates in the front part of the toilet bowl surface, which has a larger area and needs more foam coverage; the auxiliary foam outlet rotates in the rear part of the toilet bowl surface, which has a smaller area and does not need more foam coverage.
