[0020] The preferred embodiment of the utility model will be described in detail below with reference to the accompanying drawings.

[0021] As shown in the blasting dust falling device for open deep hole blasting engineering, Figure 1

[0022] ​It includes a housing 1, an atomizer 2 disposed on the upper surface of the housing 1, a water tank 3 fixedly connected to one side of the housing 1, and a positioning component disposed on the other side of the housing 1 and the water tank 3. The water tank 3 is provided with a filter component, and the water filtered in the water tank 3 is supplied to the atomizer 2 through the housing 1.

[0023] Specifically, the filtration assembly includes several parallel and vertically arranged filter screens 4 in the water tank 3 and filter elements 5 arranged in the accommodating space formed by the water tank 3 and the filter screens 4. By setting the filtration assembly in the water tank, after the water source enters the water tank 3 for storage, it will be filtered through the filter screens 4 and filter elements 5, reducing impurities in layers. This reduces the clogging of the atomizing nozzle by impurities or scale during use, increases the purification effect in the water tank 3, and is easy to disassemble.

[0024] In this preferred embodiment, the filter screen 4 is surrounded by a protective plate 6. To enhance the installation effect of the filter screen 4 and the protective plate 6, the inner wall of the water tank 3 is provided with several guide grooves 7 for limiting the position of the protective plate 6. Correspondingly, the protective plate 6 is provided with a guide rod 8 that is slidably connected to the guide groove 7. The inner bottom surface of the water tank 3 is provided with a rubber groove 9, and the lower end surface of the protective plate 6 is provided with a rubber block 10 that can be embedded in the rubber groove 9.
