[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figure 1-5 As shown:

[0028] An air source heating device includes an air source heat pump body 101, and a drive motor 102 is fixedly installed inside the air source heat pump body 101 through a crossbeam plate.

[0029] The fan blade 103 is fixedly installed at the output end of the drive motor 102 by screws. The drive motor 102 drives the fan blade 103 to rotate forward or reverse, which can realize air intake or exhaust.

[0030] The support frame 104 is fixedly installed at the mounting hole opened on one side of the air source heat pump body 101;

[0031] The filter screen 105 is fixedly installed on the outer side of the support frame plate 104 and corresponds to the fan blade 103;

[0032] A brush plate 106 is disposed on the outside of the filter screen 105 and is used to clean the dust adhering to the surface of the filter screen 105.

[0033] The drive connection mechanism 2 is installed on the support frame plate 104. When the fan blade 103 rotates, the brush plate 106 can be flexibly driven to rotate through the drive connection mechanism 2.

[0034] The drive connection mechanism 2 includes a rotating shaft 201 rotatably mounted at the center of the support frame disk 104 via a bearing, and a square rod 203 sliding on the rotating shaft 201. A first spring 202 is fixed between the square rod 203 and the rotating shaft 201. A connecting plate 204 is fixed at the end of the square rod 203 away from the first spring 202. An electromagnet 205 is fixedly mounted on one side of the connecting plate 204 through a circular groove. An iron block disk 206 corresponding to the connecting plate 204 is fixedly mounted at the center of the fan blade 103. A square groove adapted to the square rod 203 is opened on one side of the rotating shaft 201. The square rod 203 can slide in the square groove opened on the rotating shaft 201. The distance between the connecting plate 204 and the iron block disk 206 is less than the distance that the square rod 203 can move in the square groove opened on the rotating shaft 201.

[0035] In this implementation scheme: When the air source heat pump heating device is in use, the drive motor 102 drives the fan blades 103 to rotate in the forward direction to achieve the air intake function. This draws in low-temperature outdoor air into the air source heat pump body 101. The heat in the air is then transferred to the refrigerant through the evaporator inside the air source heat pump body 101. This refrigerant is usually a special low-boiling-point liquid. In the evaporator, the refrigerant absorbs heat from the air and vaporizes, becoming a low-pressure gas. The vaporized refrigerant is then compressed by the compressor, increasing its temperature and pressure. The compressed, high-temperature, high-pressure refrigerant enters the condenser inside the device. In the condenser, the high-temperature, high-pressure refrigerant exchanges heat with the indoor air or water, transferring heat to the indoor air or water. During this process, the refrigerant is cooled and liquefied into a high-pressure liquid. The liquefied refrigerant passes through the expansion valve, its pressure and temperature decreasing, and it re-enters the evaporator, ready to absorb more heat and begin a new cycle. Through this process, the air source heat pump heating device continuously extracts heat from the outdoor air and transfers it to the indoor environment, achieving a heating effect.

[0036] Meanwhile, the filter screen 105 on the support plate 104 is used to filter the intake air and reduce dust entering the air source heat pump body 101. When it is necessary to clean the dust attached to the filter screen 105, the fan blade 103 is driven to rotate in the opposite direction by the drive motor 102 to realize the exhaust function and exhaust the airflow to the filter screen 105.

[0037] At this time, when the electromagnet 205 is energized, a magnetic field is generated inside the coil of the electromagnet 205, causing it to move closer to the iron block disk 206. At the same time, the electromagnet 205 drives the square rod 203 to slide in the square groove through the connecting plate 204, and stretches the first spring 202, so that the magnetic surface of the electromagnet 205 is tightly attached to the iron block disk 206. Under these circumstances, while the drive motor 102 drives the fan blade 103 to rotate, it can also drive the iron block disk 206 to rotate, thereby driving the electromagnet 205, connecting plate 204 and other components to rotate synchronously.

[0038] While the connecting plate 204 drives the square rod 203 to rotate, it in turn drives the rotating shaft 201 to rotate. As the rotating shaft 201 rotates, the brush plate 106 also rotates. The brush plate 106 is used to clean the dust attached to the outside of the filter screen 105, reducing the adhesion of dust and thus ensuring the subsequent air intake effect.

[0039] At the same time, the drive motor 102 drives the fan blade 103 to rotate in the opposite direction, thereby generating an exhaust effect, which can more effectively blow away the dust on the filter screen 105.

[0040] After cleaning the filter screen 105, the fan blade 103 can be driven to continue to rotate forward again by the drive motor 102, thereby restoring the air intake effect. When the electromagnet 205 is de-energized and loses its magnetism, the first spring 202, which is in a stretched state, contracts, causing the iron block 206 of the electromagnet 205 to separate, and the brush plate 106 will no longer rotate.

[0041] This solution allows for flexible cleaning of the filter 105, reducing dust accumulation and ensuring efficient air intake, thus guaranteeing the normal operation of the air heat pump. This helps maintain equipment stability, reduces malfunctions and downtime caused by filter 105 clogging, improves the device's effectiveness, and meets practical application requirements.

[0042] It should be noted that all electrical equipment involved in this product is powered by an external power source. The solution also includes an electrical control cabinet, which is equipped with a timer to periodically clean the filter 105. The electrical control cabinet is installed on the air source heat pump body 101. During use, each electrical device can be started and operated separately through the electrical control cabinet. The power connection method of each electrical device is a mature existing technology and is well known to those skilled in the art. It will not be described in detail here. At the same time, all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0043] Furthermore;

[0044] In an optional embodiment, a convenient locking mechanism 3 is installed between the other end of the rotating shaft 201 and the brush plate 106. The convenient locking mechanism 3 facilitates the assembly and disassembly of the brush plate 106 and the rotating shaft 201. The convenient locking mechanism 3 includes a protrusion 301 fixed to the other end of the rotating shaft 201 and locking blocks 303 sliding on both sides of the protrusion 301. A second spring 302 arranged symmetrically is fixedly installed between the locking blocks 303 and the protrusion 301. A locking hole 305 adapted to the protrusion 301 is opened in the middle of the brush plate 106. A sliding groove is opened on the protrusion 301 to slide with the locking block 303. A limiting block 304 is fixedly installed on the inner wall of the sliding groove of the protrusion 301. An anti-detachment groove adapted to the limiting block 304 is opened on one side of the locking block 303.

[0045] In this embodiment: As the brush plate 106 is used for a long time, the brush strips may fall off continuously and need to be replaced. At this time, the second spring 302 can be compressed by pressing the locking block 303, so that the locking block 303 is fully compressed into the groove opened in the protrusion 301, thereby releasing the obstruction to the brush plate 106. In this way, the brush plate 106 can be directly removed from the protrusion 301 for replacement.

[0046] When installing a new brush plate 106, first insert the locking hole 305 of the brush plate 106 into the protrusion 301, and then fully compress the locking blocks 303 on both sides into the slide groove. After the brush plate 106 is fully inserted into the protrusion 301 through the locking hole 305, the pressure on the locking block 303 can be released. The second spring 302, which is in a compressed state, will rebound and drive the locking block 303 to extend out, thereby blocking one side of the brush plate 106. At the same time, the other side of the brush plate 106 is blocked by the protrusion 301. This completes the installation of the brush plate 106.

[0047] When the brush plate 106 rotates, centrifugal force causes part of the locking block 303 to be thrown out, ensuring the stability of the brush plate 106's blocking action. At the same time, the limiting block 304 can limit the locking block 303, ensuring that the locking block 303 will not be completely thrown out of the groove.

[0048] The working principle and usage process of this utility model: When the air source heat pump heating device is in use, the filter screen 105 on the support frame 104 is used to filter the intake air, reducing dust entering the air source heat pump body 101. When it is necessary to clean the dust attached to the filter screen 105, the drive motor 102 drives the fan blade 103 to rotate in the opposite direction to achieve the exhaust function, expelling the airflow onto the filter screen 105. At this time, the electromagnet 205 is energized. When the coil of the electromagnet 205 is energized, a magnetic field is generated inside, causing it to move closer to the iron block 206. At the same time, the electromagnet 205 drives the square rod 203 through the connecting plate 204. The electric rod slides within the square groove, stretching the first spring 202, thereby causing the magnetic surface of the electromagnet 205 to fit tightly against the iron block disk 206. In this situation, while the drive motor 102 drives the fan blade 103 to rotate, it can also drive the iron block disk 206 to rotate, thereby causing the electromagnet 205, connecting disk 204, and other components to rotate synchronously. While the connecting disk 204 drives the square rod 203 to rotate, it also drives the rotating shaft 201 to rotate. Through the rotation of the rotating shaft 201, the brush plate 106 also rotates. The brush plate 106 is used to clean the dust attached to the outside of the filter screen 105, reducing the adhesion of dust and thus ensuring the subsequent air intake effect.

[0049] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
