Most of the filters are installed and fixed in the air intake duct, which is not convenient for cleaning and disassembly. If the filter is not removed for maintenance for a long time, the filter will become clogged, reducing the filtering effect of the filter, thereby reducing the working efficiency of the air source heat pump.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-5 , the utility model provides a technical solution:

[0027] Embodiment 1

[0028] An air source heat pump comprises an air source heat pump body 1, a shell 2 is installed on the air inlet pipe of the air source heat pump body 1, an air inlet 3 is arranged at one end of the shell 2, a grille 4 is installed at one end of the air inlet 3, two inclined portions 5 are arranged inside the shell 2, a filter screen 6 is fixedly arranged between the two inclined portions 5, and a cleaning mechanism is arranged inside the shell 2;

[0029] The cleaning mechanism includes a motor 7, a rotating shaft 8, a hollow roller 9, a through hole 10 and bristles 11. The through hole 10 is arranged on the surface of the hollow roller 9. The rotating shaft 8 is fixed to the two ends of the hollow roller 9. The rotating shaft 8 passes through the shell 2 and is rotatably connected to the shell 2. The motor 7 is fixed to the bottom of the shell 2. The output end of the motor 7 is connected to the rotating shaft 8 through a synchronous component. The bristles 11 are fixed to the surface of the hollow roller 9, and the bristles 11 are in contact with the filter 6. The synchronous component includes a synchronous wheel 27 and a synchronous belt 28. The synchronous wheel 27 is fixed to the surface of the rotating shaft 8 and the output end of the motor 7. The synchronous belt 28 synchronously connects the two synchronous wheels 27.

[0030] See also Figure 1 , 2 and 3, the gas can enter the shell 2 through the air inlet 3, and after being filtered by the filter 6, it can enter the air source heat pump body 1 from the shell 2 through the gap between the hollow roller 9 and the shell 2 and the through hole 10 on the surface of the hollow roller 9. When the motor 7 is started, the motor 7 can drive the rotating shaft 8 to rotate through the synchronous wheel 27 and the synchronous belt 28, and then the rotating shaft 8 drives the bristles 11 to revolve through the hollow roller 9, so that the bristles 11 can clean the filter 6 by rotating and wiping.

[0031] It should be noted that the bristles 11 can penetrate into the mesh of the filter 6, and the impurities stuck in the mesh of the filter 6 can be pushed out by the bristles 11 and made to fall to the side of the filter 6 away from the bristles 11, so as to collect the impurities uniformly.

[0032] A dust outlet 22 is provided at the bottom of the shell 2, and a cover plate 23 is slidably provided at the bottom of the shell 2. The cover plate 23 covers the surface of the dust outlet 22. The side of the cover plate 23 is fixedly connected to the grille 4 through a connecting plate 24. A guide portion 25 is fixedly provided on the inner wall of the cover plate 23. A guide groove 26 is provided on the surface of the shell 2, and the guide portion 25 is slidably provided in the guide groove 26.

[0033] See also Figure 4 and 5 After impurities accumulate inside the shell 2, they can move to the dust outlet 22 through the inclined portion 5. After the dust outlet 22 is opened by moving the cover plate 23 laterally, the impurities can be discharged through the dust outlet 22. Since the cover plate 23 is connected to the grille 4 through the connecting plate 24, the grille 4 can move synchronously with the cover plate 23, so that the grille 4 is detached from one end of the air inlet 3, so as to facilitate cleaning of the grille 4.

[0034] Embodiment 2

[0035] In the above embodiment, the roller is cleaned by rotating and wiping on the other side of the roller, so that impurities can fall on the other side of the filter 6 and are finally discharged through the dust outlet 22. However, it is difficult to clean the filter 6 more thoroughly by only a single method. Therefore, in this embodiment, an auxiliary mechanism suitable for further cleaning the filter 6 is also provided inside the shell 2, and the auxiliary mechanism includes a traction rod 12, a baffle 13, a slide groove 14, a driving rod 15 and a knocking rod 16. The traction rod 12 is movably arranged on the surface of the shell 2 through a reciprocating mechanism, the slide groove 14 is arranged on the surface of the shell 2, the baffle 13 is fixed to one end of the traction rod 12 and covers the surface of the slide groove 14, the driving rod 15 is vertically fixed to the surface of the baffle 13 and passes through the slide groove 14, the driving rod 15 is slidably arranged on the inner wall of the shell 2, and the knocking rod 16 is fixed to the surface of the driving rod 15 and contacts the filter 6.

[0036] The reciprocating mechanism includes gear teeth 17 and a missing gear 18. The gear teeth 17 are fixedly arranged on the surface of the traction rod 12. The missing gear 18 is fixed to the surface of the rotating shaft 8 and is matched with the gear teeth 17. The traction rod 12 is movably arranged on the surface of the shell 2 through an elastic member. The elastic member includes a fixed seat 19, a guide rod 20 and a spring 21. The fixed seat 19 is installed on the side of the shell 2, and the guide rod 20 is installed on the surface of the fixed seat 19. The traction rod 12 is slidably arranged on the surface of the guide rod 20. The two ends of the spring 21 are installed between the fixed seat 19 and the traction rod 12, and the spring 21 is sleeved on the surface of the guide rod 20.

[0037] See also Figure 2 , 3 When the rotating shaft 8 rotates, it can drive the missing gear 18 to rotate synchronously. When the missing gear 18 rotates, it can drive the traction rod 12 to translate in the direction close to the air inlet 3 through the gear teeth 17. During this process, the distance between one end of the traction rod 12 and the fixed seat 19 will gradually increase, and the traction rod 12 can stretch the spring 21 at this time to deform and store energy, and the other end of the traction rod 12 can drive the baffle 13 to move on the surface of the slide groove 14. At the same time, the baffle 13 can drive the knocking rod 16 to move away from the filter screen 6 through the driving rod 15. When the missing gear 18 is just separated from the gear teeth 17, the traction rod 12 can be reset under the drive of the spring 21, so that the traction rod 12 can drive the driving rod 15 to quickly reset inside the slide groove 14 through the baffle 13, and the driving rod 15 can drive the knocking rod 16 to quickly reset, so that the knocking rod 16 can hit the surface of the filter screen 6, and the impurities on the surface of the filter screen 6 are shaken off by vibrating the filter screen 6.

[0038] It should be noted that in the above process, there is always gas entering the air inlet 3, so the airflow will cause the impurities to be pressed on the surface of the filter 6 and cannot fall off due to vibration. However, the driving source of the knocking rod 16 is a motor 7 independent of the air source heat pump body 1. Therefore, when the air source heat pump body 1 stops inhaling air, the airflow will not produce pressure on the impurities, so that the filter 6 can be cleaned through the above process.

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
