This air-source heat pump dryer includes a housing, with an air inlet pipe fixedly connected to one side of the housing. A filter screen is fixedly connected to one end of the air inlet pipe. An air outlet pipe is fixedly connected to the end of the housing away from the air inlet pipe. A return air pipe is provided on the top of the housing. A control panel is provided on the side of the housing near the air inlet pipe. A crossbar is fixedly connected to one end of the air inlet pipe, and a fixed shaft is rotatably connected to the middle of the crossbar. A scraper is fixedly connected to the side of the fixed shaft near the filter screen, and the scraper is in close contact with the surface of the filter screen. This air-source heat pump dryer, through the cooperation of the scraper, crossbar, and fixed shaft, allows for cleaning of the filter screen without disassembling it, improving cleaning efficiency. The addition of a discharge chute allows fallen dust to be directly discharged from inside the air inlet pipe, making it more convenient to use.

[0004] This patent allows for cleaning without disassembling the filter. However, while existing filters do not require disassembly for cleaning, manual operation is still necessary, making automatic cleaning impossible and thus its practicality needs improvement. Utility Model Content

[0017] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0019] Example 1, as Figure 1 - Figure 3 As shown, this utility model provides an intelligent variable frequency heat pump dryer, including a dryer body 1. An air inlet pipe 2 is provided on one side of the dryer body 1, and a filter screen 3 is connected to the surface of the air inlet pipe 2. An automatic cleaning component 4 is connected to the top of the dryer body 1 near the filter screen 3. The automatic cleaning component 4 includes a support frame 401, a motor 402 is connected to one side of the support frame 401, a connecting rod 403 is connected to the output end of the motor 402, and first gears 404 are connected to both sides of the connecting rod 403. The bottom of both sets of first gears 404 are connected to... A second gear 405 is connected, and a one-way screw 406 is connected to the bottom of the second gear 405. A set of cleaning brushes 407 are connected to the surfaces of the two sets of one-way screws 406. Threaded holes 408 are opened on both sides of the cleaning brush 407. The one-way screws 406 are threadedly connected to the cleaning brushes 407 through the threaded holes 408. The surface of the cleaning brushes 407 is in contact with the filter screen 3. The position and size of the first gear 404 match the position and size of the second gear 405. The first gear 404 and the second gear 405 are meshed together.

[0020] The effect achieved in Embodiment 1 is as follows: When the dryer body 1 has been used for a long time and the filter screen 3 on the surface of the air inlet pipe 2 has accumulated a lot of dust and needs cleaning, the reverse function of the motor 402 can be activated. The output end of the motor 402 will drive the connecting rod 403 to reverse, and the reverse rotation of the connecting rod 403 will drive the two sets of first gears 404 to reverse. The first gears 404 mesh with the two sets of second gears 405 in the opposite direction, thereby causing the two sets of one-way screws 406 to reverse simultaneously. When the one-way screws 406 reverse, they will engage with the reverse thread of the threaded hole 408 on the cleaning brush 407, driving the cleaning brush 407 to move downward, thereby cleaning the impurities and dust adsorbed on the surface of the filter screen 3, causing the dust to fall into the collection box 506. After cleaning, the motor 402 automatically starts the forward rotation function. Through the meshing connection of the gears, the two sets of one-way screws 406 rotate forward simultaneously, driving the cleaning brush 407 to move upward and return to the initial position to wait for the next cleaning. This design avoids the traditional manual cleaning method and improves the practicality of the dryer body 1.

[0021] Example 2, as Figure 1 and Figure 4 As shown, the bottom of the air inlet pipe 2 is connected to a collection assembly 5. The collection assembly 5 includes a fixing frame 501. The front end of the fixing frame 501 is provided with a feeding groove 502. Magnetic blocks 503 are provided on both sides of the inner wall of the fixing frame 501. A collection box 506 is provided inside the fixing frame 501. Magnets 507 are connected to both sides of the collection box 506. A controller 504 is connected to one side of the outer surface of the fixing frame 501. An alarm 505 is connected to one side of the controller 504. Infrared sensors 508 are connected to both sides of the inner wall of the collection box 506.

[0022] The effect achieved in Embodiment 2 is as follows: when a large amount of impurities are collected in the collection box 506, the infrared sensor 508 will automatically send an electrical signal to the controller 504, so that the controller 504 can activate the alarm 505 to remind the operator to clean the impurities in the collection box 506. The operator only needs to pull the collection box 506 outward to complete the disassembly. After the impurities in the collection box 506 are cleaned, it can be directly pushed into the fixing frame 501 and fixed by magnetic attraction between the magnetic block 503 and the magnet 507.

[0023] Working principle: When it is necessary to clean the filter screen 3 of the air inlet pipe 2, the motor 402 can be turned on to drive the one-way screw 406 to rotate, and the cleaning brush 407 is pushed downward through the threaded connection to complete the surface cleaning of the filter screen 3. This avoids the traditional manual cleaning method and improves the practicality of the dryer body 1. When there are a lot of impurities collected in the collection box 506, the infrared sensor 508 can start monitoring and activate the alarm 505 to remind the operator to clean it in time and avoid the problem of impurities overflowing from the collection box 506.

[0024] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the scope of the technical solution of this utility model shall still fall within the protection scope of the technical solution of this utility model.
