[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1-5 , a heat recovery device for an air source heat pump in a solar greenhouse, including a box body 1, an intake pipe 2 is arranged on one side of the box body 1, a drive motor 3 is arranged at the middle of one side of the box body 1, a control panel 4 is arranged on the box body 1, an exhaust pipe 6 is arranged at the bottom of the other side of the box body 1, a filter box 8 is arranged at the top of the side surface of the box body 1, one end of the exhaust pipe 6 is connected to the filter box 8, a drain pipe 7 is arranged at the bottom of the side surface of the box body 1, a fixed ring pipe 11 is arranged inside the box body 1, one end of the fixed ring pipe 11 is connected to the intake pipe 2, the other end of the fixed ring pipe 11 is connected to the exhaust pipe 6, a stirring rod 10 is arranged at the middle inside the box body 1, the output end of the drive motor 3 is connected to the stirring rod 10, a temperature sensor 12 is arranged on one side of the inner bottom of the box body 1, a filter screen 20 is arranged inside the filter box 8, and both the temperature sensor 12 and the drive motor 3 are electrically connected to the control panel 4.

[0025] In the actual use process of the above structure, the heat inside the sunlight greenhouse enters the inside of the fixed ring pipe 11 through the air inlet pipe 2, and the water source inside the box body 1 is heated by the heat, so that it is heated into hot water, which is convenient for supply to other places. During the recycling process, the driving motor 3 can be started. The driving motor 3 drives the stirring rod 10 to rotate, and the rotation of the stirring rod 10 makes the water source inside the water tank flow quickly, so that the water source is heated evenly and sufficiently. The exhaust gas after heating the water source enters the inside of the filter box 8 through the exhaust pipe 6, and is filtered by the filter screen 20 inside the filter box 8 to avoid the direct emission of the gas with dust, ensuring the air quality of the surrounding area and having stronger practicability.

[0026] In this embodiment, a connection groove 13 is arranged inside one side of the filter box 8. The filter screen 20 is slidably connected with the connection groove 13. A connecting plate 9 is arranged on one side of the filter screen 20. Card slots 21 are arranged inside both sides of the bottom end of the connecting plate 9. A fixing frame 14 is arranged at the bottom of one side of the filter box 8. Fixing rods 15 are arranged on both sides inside the fixing frame 14. Springs 16 are arranged on the fixing rods 15. The springs 16 are sleeved on the fixing rods 15. A movable plate 17 is arranged on the fixing rods 15. The movable plate 17 is slidably connected with the fixing rods 15. The top end of the spring 16 abuts against the movable plate 17. Clamping blocks 19 are arranged on both sides of the top end of the movable plate 17. One end of the clamping block 19 abuts inside the card slot 21. A pulling plate 18 is arranged at the middle of the bottom end of the movable plate 17. When it is necessary to disassemble and clean the filter screen 20, directly manually pull the pulling plate 18, so that the pulling plate 18 drives the movable plate 17. The movable plate 17 compresses the spring 16 on the fixing rod 15, and further makes the clamping block 19 at the top of the movable plate 17 withdraw from the card slot 21 of the connecting plate 9. At this time, the connecting plate 9 loses its limit, and the filter screen 20 can be pulled out of the connection groove 13 through the connecting plate 9, thus facilitating cleaning. And through the way of the clamping block 19 and the card slot 21, the installation and disassembly of the filter screen 20 are both relatively simple and fast, and the practicability is stronger.
