[0034] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0035] In summary, with the aid of the above-mentioned technical solution of this utility model, the liquid to be treated is transported through the filter mechanism 3 connected to the conveying mechanism 2 during use. When the liquid enters the filter box 302 through the inlet pipe 303, the filter box 302 is filled with activated carbon plate 305 and ion exchange resin plate 306 to remove calcium, magnesium ions and other impurities that may cause scale, ensuring the purity of the liquid entering the system and avoiding scale adhesion that affects heat exchange efficiency. The purified liquid is stored in the storage tank 201, and the interior of the storage tank 201 is divided into a hot water chamber and a cold water chamber by the heat insulation plate 202. The water chamber has two independent spaces to prevent cross-conduction of heat. One side of the liquid storage tank 201 is equipped with multiple inlet and outlet pipes 203, which are connected to the control valve 301, while the other side has a delivery pipe 210. The delivery pipe 210 and the inlet and outlet pipes 203 pass through the liquid storage tank 201 and are connected to key components in the energy-saving heat pump body 1, such as the circulating water pump 204, condenser 205, expansion valve 206, compressor 207, gas-liquid separator 208 and evaporator 209, to ensure that hot water and cold water can circulate effectively in their respective spaces and complete the heat transfer process through the core components of the heat pump.

[0036] Circulating water pump 204: Responsible for driving the flow of liquid throughout the system.

[0037] Condenser 205: Receives high-temperature and high-pressure refrigerant vapor from compressor 207 and cools it into a liquid state, while releasing heat to the surrounding environment or objects that need to be heated.

[0038] Expansion valve 206: Reduces the pressure of the refrigerant, causing its temperature to drop, in preparation for it to enter the evaporator 209.

[0039] Compressor 207: Increases the pressure and temperature of the refrigerant, and is the power source for the entire refrigeration cycle.

[0040] Gas-liquid separator 208: ensures that only gaseous refrigerant returns to compressor 207, protecting compressor 207 from liquid shock.

[0041] Evaporator 209: Absorbs heat from the external environment or the object to be cooled, causing the refrigerant to evaporate into low-temperature, low-pressure vapor.

[0042] To maintain good ventilation and heat dissipation, a protective mechanism 4 is installed above the energy-saving heat pump body 1. The protective mechanism 4 includes a protective cylinder 401, with a rotating rod 404 driven by a servo motor 403 fixed in its center. The rotating rod 404 is equipped with blades 405 to promote air circulation. In addition, a cleaning brush 407 is installed on the surface of the rotating rod 404. As the rotating rod 404 rotates, the cleaning brush 407 automatically cleans impurities on the filter screen 406, keeping the ventilation opening unobstructed, thereby improving the heat dissipation effect and reducing the increase in energy consumption caused by poor heat dissipation. The filter cover 304 is equipped with a sealing gasket 5 and is fixed by a latch 6, which enhances the sealing performance of the filter mechanism 3 and facilitates maintenance or replacement. At the same time, the liquid storage tank 201 is equipped with multiple heat dissipation fins 7. In particular, the heat dissipation fins 7 located in the hot water chamber help to accelerate the dissipation of heat to the outside and maintain the stable operation of the system. The energy-saving heat pump body 1 is filled with sound insulation cotton 8 to reduce the noise generated during equipment operation. The bottom support frame 9 of the energy-saving heat pump body 1 and its fixing screws 10 provide additional support to ensure the safety and reliability of the entire device.
