When the air pump 6 is started to evacuate the liquid storage chamber 11, the movable core 73 overcomes the elastic force of the spring 74 and moves upward under the suction force of the air pump 6 until the second communication port 751 is closed, thereby disconnecting the first air port 711 from the second air port 721. Fig. 9 shown.

[0060] The working principle of a liquid mixing device of the present invention will be described below.

[0061] See also Figure 1-Figure 10 As shown, a foaming device of the present invention comprises a foaming module 8 capable of generating foam, wherein the foaming module 8 is provided with a third liquid inlet 81 and a foaming outlet. The present invention also comprises a liquid mixing device of the present invention as described above, wherein the second liquid outlet 123 of the dilution chamber 12 is connected to the third liquid inlet 81 of the foaming module.

[0062] In this embodiment, the foaming module 8 is further provided with an air inlet 82, and the air outlet of the air pump 6 is connected to the air inlet 82.

The above-mentioned driving mechanism can be realized by using a motor 10 combined with a gear transmission assembly, and drives the bubble spray tube 9 to rotate 180 degrees. Fig.12 shown.

[0064] A foaming device of the present invention is applied to a toilet, such as Figure 11-Figure 15 As shown, its working principle is as follows:

[0065] Adding liquid: The universal foaming stock liquid (i.e., detergent, hand soap, etc.) is poured into the liquid storage chamber 11 of the box body 1 from the liquid adding port 13. Since the universal foaming stock liquid has a high viscosity, it is necessary to turn on the air pump 6 to evacuate the liquid storage chamber 11, thereby accelerating the universal foaming stock liquid to flow into the liquid storage chamber 11. At this time, the three-way module 7 is in a working state, and the movable core 73 of the three-way module 7 is sucked up and blocks the second connecting port 751, so that the negative pressure acts entirely on the liquid storage chamber 11. After the liquid pouring is completed, the air pump 6 stops evacuating the liquid storage chamber 11, and the three-way module 7 resets the movable core 73 through the spring 74 and opens the second connecting 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 connected to each other, so that the liquid storage chamber 11 is connected to the outside atmosphere, and the special foaming agent can be directly poured in without using the air pump 6 to evacuate the negative pressure.

[0066] Liquid mixing: The liquid pump 2 extracts an appropriate amount of foaming raw material from the liquid storage chamber 11 of the box body 1 into the primary dissolution chamber 35, and at the same time, the water pump 4 pumps water into the water inlet chamber 34 of the dissolution chamber (another water enters the dilution chamber 12 of the box body 1), and the water entering the water inlet chamber 34 is injected into the primary dissolution chamber 35 through various water passes to form turbulence and eddy currents, which impact and break up the foaming stock solution in the primary dissolution chamber 35, so that the foaming raw material is initially dissolved in the primary dissolution chamber 35, and enters the secondary dissolution chamber 36 through the first connecting port for further dissolution. The final water pressure pushes the fully dissolved foaming stock solution into the dilution chamber 12 of the box body 1 to mix and dilute with the other water provided by the water pump 4.

[0067] Foaming: The diluted foaming liquid is pushed by the water pressure of the water pump 4 and transported to the foaming module 8. The foaming liquid enters the cavity from the third liquid inlet 81 of the foaming module 8. The diameter of the third liquid inlet 81 suddenly decreases during the process of entering the cavity to increase the kinetic energy of the liquid. At the same time, the air blown out by the air pump 6 enters the cavity of the foaming module 8. The air and the foaming liquid are mixed to produce a large number of bubbles with strong kinetic energy. The air blown out by the air pump 6 comes from the air that enters the liquid storage chamber 11 through the liquid filling port 13. Since the liquid filling port 13 leads to the outside at this time, the liquid storage chamber 11 is not in a closed state. Therefore, the air pump 6 will not draw away the foaming stock liquid in the liquid storage chamber 11 when pumping air. The bubble water becomes more delicate foam particles after passing through the two layers of fine mesh inside the foaming module 8. Since the cross-sectional area of ​​the main bubble channel 93 of the bubble jet tube 9 is larger than that of the secondary bubble channel 94, and the caliber of the main bubble outlet 91 is smaller than that of the secondary bubble outlet 92, after the foam particles are diverted by the bubble jet tube 9, most of the foam particles enter the main bubble channel 93 with a larger caliber, and are ejected through the main bubble outlet 91 with a smaller caliber. By changing the size of the channel, the foam particles can be ejected to a farther pot surface with increased pressure; while a small part of the foam particles are ejected through the secondary bubble channel with a small caliber to the secondary bubble outlet 92 with a large caliber. At this time, there are few foam particles and the ejection channel is large, so the pressure becomes smaller, and a small amount of foam particles flow out from this bubble outlet. The main bubble outlet 91 rotates in the front part of the toilet pot surface, and this part of the area is larger and needs more foam coverage; the secondary bubble outlet 92 rotates in the back part of the toilet pot surface, and this part of the area is smaller, so it does not need more foam coverage.

[0068] When working normally, the flow rate of the water pump 4 is 0.5L / min-0.9L / min, the flow rate of the air pump 6 is 2-3L / min, and the liquid pump 2 pumps 1-4g of liquid each time, which can achieve a good foaming effect. Each time the liquid pump 2 pumps the foaming stock liquid, it can be used for foaming four times.

[0069] Therefore, the dissolving chamber of the present invention is set up because the general consumables (such as detergent, hand soap and other high viscosity liquids) are used as the foaming stock solution. If the general consumables are not further dissolved, the foaming effect will be greatly reduced. The caliber of the first liquid inlet 311 is made smaller than the caliber of the first water inlet 312. In this embodiment, the caliber of the first liquid inlet 311 and the caliber of the first water inlet 312 are set to be 1 / 2, which helps to reduce the amount of general consumables.
