As an embodiment of the present invention, as shown in fig. 2 and 7, a ceramic washer 351 is fixedly connected to each of the positions where the two fixing lugs 35 contact with the pull rod 34, and the pull rod 34 is slidably connected to the inner side surface of the ceramic washer 351.

During operation, based on the above embodiment, when the pull rod 34 continuously moves up and down, friction is generated between the pull rod 34 and the fixing lug 35, friction loss between the pull rod 34 and the fixing lug 35 is reduced due to the arrangement of the ceramic washer 351, smooth movement of the pull rod 34 is ensured, and accordingly the scraping effect on the air hole 13 is improved.

The working principle is as follows: the machine set is started, the compressor 12 compresses low-temperature low-pressure refrigerant gas into high-temperature high-pressure gas, the high-temperature high-pressure refrigerant gas from the compressor 12 flows through the condenser 11 through the guide pipe, the fan 15 continuously releases heat to the outside, so that medium-temperature high-pressure refrigerant liquid is condensed, the dust screen 16 is fixedly connected to the opening of the air duct 14 through screws, dust is prevented from entering the machine body 1 through the air duct 14, meanwhile, the dust screen 16 is convenient to disassemble for later maintenance, the starting motor 71 drives the driving gear 76 to rotate, the rotating shaft 74 at the front side of the driving gear 76 is fixedly connected with the central position of the rear side of the rotating disc 31, so that the rotating disc 31 is driven to rotate, the lower end of the crank 33 is hinged with the hinge shaft 32 above the front side of the rotating disc 31, the upper end of the crank 33 is hinged with the lower end of the pull rod 34, so that the crank 33 eccentrically rotates under the drive of the rotating disc 31, thereby driving the pull rod 34 to continuously move up and down, the scraper 36 is driven by the pull rod 34 to move up and down, thereby driving the brush 37 to continuously scrape the air hole 13, preventing dust from blocking the air hole 13 in the working process of the unit, the brush 37 is fixedly connected on the scraper 36 through screws, facilitating the later-stage disassembly and maintenance of the brush 37, the pull rod 34 can generate friction with the fixing lug 35 when continuously moving up and down, the arrangement of the ceramic gasket 351 reduces the friction loss between the pull rod 34 and the fixing lug 35, simultaneously ensuring the smooth displacement of the pull rod 34, improving the scraping effect on the air hole 13, improving the ventilation effect, thereby improving the heat exchange efficiency, further prolonging the service life of the device, the water storage tank 24 can collect rainwater, the filter screen 25 at the notch position of the water storage tank 24 can filter dust and impurities in rainwater and prevent dust in air from falling into the water storage tank 24, thereby avoiding the dust from blocking the pipeline, the water in the water storage tank 24 enters the water drum 22 through the sewer pipe 23, the motor 71 drives the driving gear 76 to rotate anticlockwise so as to drive the driven gear 73 to rotate clockwise, the driving gear 76 on the right side of the gear cavity 72 and the teeth of the driven gear 73 are far away from each other, thereby forming low pressure, the water in the water drum 22 enters the right cavity of the gear cavity 72 through the water outlet pipe 6, and then is pushed to the left cavity of the gear cavity 72 by the wall body of the right cavity, the driving gear 76 on the left side of the gear cavity 72 and the teeth of the driven gear 73 are close to each other, thereby forming high pressure, further, the water entering the left cavity of the gear cavity 72 enters the water inlet pipe 8, the pressurized water enters the coil pipe 42 through the water inlet pipe 8, the heat dissipation fins 41 conduct the heat inside the condenser 11 to the rear ends of the heat dissipation fins 41, because the left and right ends of the heat dissipation fins 41 penetrate into the coil pipe 42, therefore, the water flowing fast in the coil pipe 42 can take away a large amount of heat on the heat dissipation fins 41, thereby increasing the heat release speed of the refrigerant gas in the condenser 11 and the heat dissipation speed of the machine body 1, further improving the heat exchange efficiency and the heat dissipation effect of the machine body 1, prolonging the service life of the equipment, the pressurized water flows out through the coil pipe 42 and enters the water cylinder 22 through the return pipe 5, because the return pipe 5 is communicated with the rear side of the lower end face of the water cylinder 22, the water in the return pipe 5 can impact the turbine blades 91 when entering the water cylinder 22, thereby driving the turbine blades 91 to rotate, the turbine blades 91 continuously rotate so as to continuously stir the water in the water cylinder 22, thereby increasing the outward heat release speed of the water absorbing the heat on the heat dissipation fins 41, ensuring that the water in the water cylinder 22 is always kept at the room temperature state, further ensuring the heat dissipation effect of the water, and ensuring that the water entering the water cylinder 22 can only flow out through the water outlet pipe 6 due to the arrangement of the check valve 51, the water can not flow out through the return pipe 5, thereby ensuring the recycling of the water, improving the heat dissipation effect and saving the water resource.
