After the water pump 18 is powered on, the water inside the water tank 1 flows into the water pump 18 through the first water pipe 17.

[0028] like Figure 1-5 As shown, the side of the water pump 18 away from the first water pipe 17 is connected to the second water pipe 19, and the end of the second water pipe 19 away from the water pump 18 is connected to the bottom of the water distribution pipe 5.

[0033] Working principle: First, the refrigerant liquid flows into the liquid inlet shell 25, and exchanges heat with the external air when flowing through the heat exchange tube 26, absorbing the heat in the air. The fins 27 on the heat exchange tube 26 can increase the surface area of ​​the heat exchange tube 26 and improve the heat exchange efficiency of the heat exchange tube 26. Then, the external power supply of the second motor 22 is turned on. The second motor 22 is connected to the external power supply through wires. The model of the second motor 22 is: YE3-80M, and the rated power is: 700W; the second motor 22 is fixed to the bottom of the ventilation top plate 20 through the pressure plate 21. After the second motor 22 is powered on, it will drive the fan blade group 23 to rotate. The rotating fan blade group 23 will generate wind to accelerate the air circulation. The accelerated air is discharged from the device When entering from the side, when flowing through the heat exchange tube 26 and the fin 27, the heat exchange between the refrigerant and the air will be accelerated under the action of air circulation. When flowing through the dustproof plate 24, part of the dust will be isolated under the action of the dustproof plate 24. After the heat exchange, it will flow into the air source heat pump through the liquid outlet shell 28 to release the heat. The air source heat pump compresses the refrigerant into high-pressure and high-temperature gas to release the heat, and then transfers the heat to the indoor air or hot water through the condenser. If the device is used for a long time, the dust attached to the heat exchange tube 26 and the fin 27 will affect the use of the device. First, rotate and open the pipe cover 16, and fill the water storage tank 1 with water through the water injection pipe 15. Then turn on the external power supply of the water pump 18. The water pump 18 is connected to the outside of the wire. The power supply is connected, the model of the water pump 18 is: ISW32-160, and the rated power is: 1.5W; after the water pump 18 is powered on, the impeller in the pump body is rotated through the driving device to generate centrifugal force, and the water inside the water storage tank 1 flows into the water pump 18 through the first water pipe 17. After being pressurized by the water pump 18, it will flow through the second water pipe 19, and then be sprayed out through the nozzle 6 on the water distribution pipe 5 to wash the dust attached to the heat exchange tube 26 and the fin 27. In order to make the washing range larger, the external power supply of the first motor 14 is turned on, and the first motor 14 is connected to the external power supply through wires. The model of the first motor 14 is: DOY106, and the rated power is: 750W; the first motor 14 is connected to the external power supply through an L-shaped rod 13 is fixed on the outside of the main housing 2. When the first motor 14 is energized, it will drive the power rod 11 to rotate. The end of the second crank 12 that rotates with the power rod 11 and is away from the power rod 11 will make a circular motion, and drive the transmission rod 10 and the fixedly connected limit sleeve 9 to make a circular motion together. The lateral displacement of the circular motion will be offset by the movement of the limit sleeve 9 along the axial direction of the limit rod 8. The longitudinal displacement of the circular motion will make the limit rod 8 drive the main rod 4 through the first crank 7 to repeatedly swing inside the shaft plate 3. The repeated swinging of the main rod 4 will also drive the water distribution pipe 5 and the nozzle 6 to repeatedly swing, so that the water sprayed by the nozzle 6 has a larger range and will not continuously flush the same place, thereby avoiding damage to the device.
