[0020] In this embodiment, a drain pipe 18 is connected to the side of the back of the water tank 2, and the sewage in the water tank 2 can be discharged when the water in the water tank 2 is replaced.

[0021] In this embodiment, a plurality of air outlet holes 19 are provided on the air inlet branch pipe 5 extending to the bottom of the water tank 2 to disperse the air and increase the contact area between the air and the water, thereby improving the dust removal and cooling effects.

[0022] In this embodiment, the air inlet end of the blower 1 is threadedly connected to a filter cartridge 20 , and a filter screen 21 is provided in the filter cartridge 20 to prevent debris from entering the blower 1 and ensure the smooth operation of the blower 1 .

[0024] In this embodiment, the control panel 17 is electrically connected to the blower 1, the electric heating tube 7, the water pump 12 and the semiconductor refrigeration plate 16, and is used to control the start and stop of the device.

[0025] The semiconductor refrigeration plate used in this application is an existing product, for example: the semiconductor refrigeration plate of the Shixun brand, model TEC1-12703, which is an existing mature technology. Its specific internal structure and principle belong to the technical scope that ordinary technicians in this field can understand, and will not be repeated here.

[0026] The principle and advantages of the present invention are as follows: open the sealing cover 22, pour clean water into the water tank 2, the water level is below the air inlet port of the air outlet branch pipe 6, and then connect the control panel 17 to the power supply.
