As shown in Figure 1, the utility model provides an air purification device, the air purification device includes a housing 1 with an air inlet 11 and an air outlet 12, the inside of the housing 1 is provided with a water storage tank for containing the liquid 22 used for purifying the air The chamber 2 and the atomization reaction chamber 3 located above the water storage chamber 2 and communicating with the water storage chamber 2, the atomization reaction chamber 3 is provided with an atomization nozzle 32, and the atomization nozzle 32 passes through the water diversion pipeline 4 communicates with the liquid 22 contained in the water storage chamber 2, wherein the atomization reaction chamber 3 is located between the air inlet 11 and the air outlet 12.

Therefore, the liquid 22 used to purify the air in the water storage chamber 2 is transported to the atomizing nozzle 32 through the water diversion pipeline 4 to form a spray 33, which rinses and dissolves the air entering the atomizing reaction chamber 3 through the air inlet 11. And absorb impurities and harmful substances in the air, and make them fall into the water storage chamber 2 below the atomization reaction chamber 3. This process can effectively remove pollutants such as particulate matter and photochemical smog in the air, and achieve the effect of purifying the air. The air purification device provided by the utility model can deeply purify the air, and has low cost and strong practicability. In addition, in terms of structure, the atomizing nozzle 32 communicates with the water storage chamber 2 through the water diversion pipeline 4 to realize the circulating flow of the liquid 22 , which is ingenious in design and strong in practicability.

In a preferred embodiment of the present utility model, as shown in FIG. 1 , the water diversion pipeline 4 includes a pipeline 43 and a booster pump 42 and a filter 41 arranged on the pipeline 43 , and the liquid 22 in the water storage chamber 2 Under the pressure of the booster pump 42, it enters the filter 41, and the filtered liquid 22 is delivered to the atomizing nozzle 32 through the pipeline 43 to form a spray 33, wherein the liquid 22 can be a weakly alkaline solution, and its components include but are not limited to Sodium hydroxide, water. The filter 41 is located upstream of the booster pump 42 and is connected to the upper liquid 22 in the water storage chamber 2 for filtering impurities in the liquid 22, and the filtered liquid 22 is transported to the water diversion pipeline 4 through the booster pump 42 , can not only reduce the wear and tear of the booster water pump 42 when it is working, but also prevent the pipeline 43 and the atomizing nozzle 32 from being blocked, and the liquid 22 from flowing smoothly. Among them, the filter 41 can use a 1 micron precision PP cotton filter element, in addition Other filters known in the art are employed.

In this embodiment, the inner wall of the atomization reaction chamber 3 is provided with a partition 31 extending obliquely downward.
