The air flow mechanism 20 sucks dirty air in the room through the air inlet 11, and the dirty air is purified in the housing 10 to form clean and fresh air and returns to the room through the air outlet 12. The water inlet 13 is connected with an external water pipe, the water flow mechanism 30 injects a certain amount of clean water into the shell 10 through the water inlet 13, and the clean water forms water mist and dirty air action in the shell 10 to purify the dirty air. The outlet 14 is connected to an external sewer pipe (for example, for general indoor air purification) or a flush pipe of a toilet (for example, for toilet air purification), and discharges the air-purified sewage into a sewer.
In this embodiment, a first partition 15 is transversely disposed in the housing 10, and the first partition 15 divides the space in the housing 10 into an upper portion and a lower portion. Preferably, the first partition 15 is located near the top of the housing 10, and the upper space 19 is much smaller in height than the lower space. A second partition 16 is vertically arranged in the lower space, and the second partition 16 divides the lower space into a front part and a rear part, which are respectively called a first space 17 and a second space 18 below. The air inlet 11 is formed at the bottom of the first space 17; the exhaust port 12 is formed at one side of the upper space 19. The air flow mechanism 20 and the water flow mechanism 30 are arranged side by side in the second space 18, and the water flow mechanism 30 is located on the left side of the second space 18 and the air flow mechanism 20 is located on the right side as viewed in the drawing direction. The water inlet 13 and the water outlet 14 are formed at the bottom of the second space 18 and are arranged corresponding to the water flow mechanism 30.
Referring to fig. 4-6, the airflow mechanism 20 includes at least one fan, which is operated to generate negative pressure to draw the outside dirty air into the housing 10. In this embodiment, the airflow mechanism 20 includes two centrifugal fans arranged in parallel, and each fan 20 includes a housing 22 and an impeller 24 rotatably disposed in the housing 22. In other embodiments, the fan 20 may also be an axial flow fan, or an axial flow fan and a centrifugal fan are collocated, and the fans 20 may also be arranged in series. The air inlet 26 of each fan 20 faces the second partition 16, and the air outlet 28 faces the first partition 15. A certain gap is left between the first partition 15 and the fan 20 to form a mixing chamber 50.

The water flow mechanism 30 includes a water inlet pipe 32, and a solenoid valve 34 connecting the water inlet pipe 32 and the water inlet 13. The end of the inlet pipe 32 is open, and the inlet water directly flows into the second space 18 of the housing 10 when the solenoid valve 34 is opened. Preferably, the solenoid valve 34 is connected to a control system, and is opened periodically to inject a certain amount of water into the casing 10, so that a certain amount of water is kept in the casing 10, and also can be opened and closed automatically according to the level of the water in the second space 18, so that the water level in the casing 10 is within a designed range, as shown by the dotted line in fig. 2, so that the blades at the bottom of the impeller 24 of the fan 20 are at least partially submerged in the water. In other embodiments, the solenoid valve 34 may be replaced with a water pump, a mechanical ball valve, or the like. Preferably, the water outlet 14 is further connected with an overflow pipe 36, the height of the overflow pipe 36 is equal to the designed height of the water level in the second space 18, when the solenoid valve 34 is opened to inject water into the housing 10, the excess water is discharged outwards through the overflow pipe 36 and the water outlet 14, so that not only is the water in the housing 10 kept at a certain height, but also the water in the housing 10 is kept at a certain cleanliness, and meanwhile, when the solenoid valve 34 is abnormal and water continues to be fed, the excess water is discharged outwards through the overflow pipe 36 and the water outlet 14, thereby avoiding the water amount from being too large to affect the use and safety of the water mist air purification device of the present invention.
When the water mist air purification device is used, the impeller 24 of the fan 20 rotates at a high speed, outside dirty air flows into the first space 17 from the air inlet 11, then flows through the through hole 160 of the second partition plate 16, and enters the inside of the fan 20 from the air inlet 26 of the fan 20; meanwhile, due to the rapid cutting of the impeller 24, part of water is atomized under the action of the impeller 24 to form water mist. The mist is mixed with the dirty air in the fan 20 and then enters the mixing chamber 50 through the outlet of the fan 20 as indicated by the arrow in fig. 2. In the process of flowing through the mixing chamber 50, the air is fully mixed with the water mist, and PM2.5 particles, large-particle dust and the like in the air are adsorbed and transferred in the water mist; indole and skatole in odor molecules are carried in water mist; hydrogen sulfide and ammonia in odor molecules are dissolved in the water mist, so that the effect of primarily purifying air is achieved, and basically clean air is formed.
Preferably, a waterproof member 52, such as a grille, is further disposed in the first space 17, and the grille 52 is located substantially at a side (shown as a left side) of the fan 20 and is inclined downward toward a side where the fan 20 is located, so that even if a small amount of water is splashed outward by the air inlet 26 under the action of the impeller 24 of the fan 20, the splashed water flows back downward under the guidance of the inclined grille 52 and is sucked by the high-speed airflow of the fan 20. It should be understood that the flashing 52 may also be a screen, mesh, or the like. Preferably, a waterproof partition plate 54 is further disposed in the first space 17, and the waterproof partition plate 54 is integrally connected between the second partition plate 16 and the front side plate of the housing 10, and is located above the air inlet 11 and below the through hole 160 of the second partition plate 16, so as to prevent the splashed water from dropping from the air inlet 11 to the outside.
An opening 150 is formed at the left side of the first partition 15, i.e., at a position corresponding to the water flow means 30, to communicate the second space 18 with the upper space 19. Preferably, a gas-liquid separating member 56, such as a grille, is further disposed between the water flow mechanism 30 and the air flow mechanism 20, the grille 56 is inclined downward toward a side opposite to the side where the fan 20 is located, so that the air and the mist mixed in this way are forcibly turned and flow obliquely downward while passing through the grille 56, the mist carrying the contaminants of the air moves downward under the action of centrifugal force and gravity, and finally is condensed into large droplets and drops downward, so as to be separated from the purified substantially clean air, and the dropped contaminated water is finally discharged into a sewer pipe through the water discharge port 14 without causing secondary pollution. It should be understood that the gas-liquid separator 56 may also be a screen, mesh, or the like.

Because the water mist firstly purifies the air, PM2.5 particles, large-particle dust, odor molecules and the like in the air are basically removed, and the air cannot pollute the photocatalyst net 44 to cause physical failure; the air and the water mist are mixed to enable the air to be rich in water molecules, so that the photocatalyst net 44 is in contact with sufficient water, and the photocatalyst net 44 can be kept to continuously and efficiently degrade organic pollutants in the air.
Preferably, a turning air duct 58 is formed in the upper space 19, the air duct 58 is arranged corresponding to the exhaust port 12, and the formed clean and healthy fresh air is forcibly turned for many times in the process of passing through the air duct 58, so that kinetic energy is converted into pressure energy, and the wind noise is effectively reduced, so that the water mist air purification device has lower operation noise and more comfortable user experience.
The fan 20 of the water mist air purification device atomizes water while sucking external dirty air, removes odor molecules, PM2.5 particles, large-particle dust and the like in the dirty air by using the water mist, arranges a waterproof piece 52 at the air inlet of the fan 20 to prevent water from splashing, arranges a gas-liquid separation piece 56 at the rear end of the mixing cavity 50 to promote the separation of clean air and dirty water phase after water mist purification, and effectively improves the purification effect. In addition, the photocatalyst net 44 is arranged on the air outlet path of the clean air, so that pollutants in the formed basically clean air are degraded, harmful bacteria are killed, clean and healthy fresh air is formed, the purification speed is high, and the purification effect is good. The water mist transferring odor molecules, PM2.5 particles, large-particle dust and the like is condensed into water and finally discharged into a sewer, no consumable material is needed in the operation of the whole purifying device, no harmful by-product is generated, the use cost is low, more importantly, the odor molecules can not be diffused into the air again and can not remain in the water mist air purifying device, the air is purified fundamentally, and no secondary pollution exists.
