The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0025] The following describes an embodiment of the present invention based on its overall structure.

[0026] An air source heat pump hot air blower system, such as Figure 1-6 As shown, it includes a hot air blower 100, an air inlet 110 is provided at the rear end of the hot air blower 100, and a cleaning component 200 is provided inside the air inlet 110;

[0027] The cleaning component 200 includes a servo motor 210 fixedly connected to one side of the top of the air inlet 110, the output end of the servo motor 210 is fixedly connected to the first winding shaft 220, the surface of the first winding shaft 220 is wrapped with a first filter screen 230, and two groups of guide shafts 231 are provided on both sides of the surface of the first filter screen 230 to change its extension direction, the end of the first filter screen 230 away from the first winding shaft 220 is fixedly connected to the second filter screen 270, and the second filter screen 270 is provided with a second winding shaft 280 inside. The output end surface of the servo motor 210 is rotatably connected to the first belt 240, and the inner wall of the first belt 240 away from the servo motor 210 is rotatably connected to the rotating shaft 250, and the lower end of the surface of the rotating shaft 250 is rotatably connected to the second belt 260, and the inner wall of the second belt 260 away from the rotating shaft Another set of rotating shafts 250 is provided on one side of the shaft 250, and a reciprocating screw rod 251 is fixed at the middle end of the surface of the two sets of rotating shafts 250. The surfaces of the two sets of reciprocating screw rods 251 are rotatably connected with a threaded sleeve 2910, and an insertion rod 2920 is welded on one side of the threaded sleeve 2910. A straight groove 2921 is opened on one side of the insertion rod 2920, and a fixed block 2930 is provided directly below the insertion rod 2920. An arc plate 2940 is provided on one side of the fixed block 2930, and the fixed block 2930 and the arc plate 2940 are connected by a hinge. Two sets of springs 2950 are provided on the side of the arc plate 2940 away from the fixed block 2930, and knocking rods 2960 are fixedly connected on both sides of the arc plate 2940 away from one end of the spring 2950. Arc-shaped partitions 2970 are provided on the front and back of both sides of the first filter screen 230.

[0028] When the hot air blower 100 is in use, the first filter 230 and the second filter 270 can effectively filter dust and impurities in the air. When used for a long time, a large amount of impurities will adhere to the filter. By starting the servo motor 210, the first reel 220 is driven to rotate, so that the first reel 220 reels the first filter 230, and the first filter 230 pulls the second filter 270 to move synchronously, so that the second filter 270 blocks the air inlet 110. The alternating use of the two filter screens 270 can effectively avoid clogging or damage caused by long-term operation of a single set of filter screens, thereby extending the overall service life of the filter screens. The servo motor 210 will also drive the first belt 240 to rotate when it is started. The first belt 240 drives the rotating shaft 250 to rotate. The rotating shaft 250 drives another set of rotating shafts 250 to rotate through the second belt 260. The rotating shaft 250 drives the reciprocating screw rod 251 to rotate while rotating. Then, the reciprocating screw rod 251 drives the threaded sleeve 2910 to rotate. The threaded sleeve 2910 moves up and down repeatedly. When the threaded sleeve 2910 descends, it drives the insertion rod 2920 to insert into the inclined groove 2931 inside the fixed block 2930, so that the fixed block 2930 drives the arc plate 2940 to squeeze the spring 2950. When it continues to descend, the fixed block 2930 will enter the straight groove 2921. Under the force of the spring 2950, ​​the knocking rod 2960 knocks on the surface of the first filter 230 and the second filter 270, thereby effectively removing impurities such as dust and particulate matter accumulated on the surface of the filter, thereby restoring its filtering efficiency. The rate can better capture pollutants in the air, improve indoor air quality, and avoid device performance degradation or failure due to blockage. When the rod 2920 rises, the hinge will flip the fixed block 2930 to disengage it from the straight groove 2921, thereby achieving reciprocating knocking. At the same time, two sets of arc-shaped partitions 2970 can isolate the position where the filter is knocked from the inside of the device to prevent dust from flying into the device when it falls. The fallen dust will be collected and processed in a centralized manner through the collection box 2980.

[0029] Please refer to Figures 1 to 3 The first filter screen 230 is installed at the air inlet 110 , and the first filter screen 230 is slidably connected to the air inlet 110 , and a torsion spring 290 is provided at both upper and lower ends of the second winding shaft 280 .

[0030] By providing the torsion spring 290 , the second reeling shaft 280 can reel in the second filter screen 270 when the servo motor 210 is reversed, thereby achieving the purpose of alternating use.

[0031] Please refer to the figure carefully. An inclined groove 2931 is provided inside the fixed block 2930 to match the insertion rod 2920. The bottom end of the insertion rod 2920 passes through the top of the air inlet 110 and is slidably connected thereto. One end of the spring 2950 is fixedly connected to the arc plate 2940, and the other end of the spring 2950 is fixedly connected to a side arc partition 2970.

[0032] The inclined groove 2931 is provided to facilitate the fixing block 2930 to squeeze the spring 2950, ​​thereby achieving the subsequent knocking action on the filter.

[0033] Please refer to Figures 2 to 6 The arc-shaped partition 2970 is arranged on both sides of the guide shaft 231, and the arc-shaped partition 2970 is fixedly connected to the air inlet 110. The end of the knocking rod 2960 is attached to the surface of the first filter 230. A collection box 2980 is provided directly below the arc-shaped partition 2970, and the collection box 2980 is slidably connected to the air inlet 110.

[0034] The arc-shaped partition 2970 can be provided to isolate the interior of the hot air blower 100, thereby preventing dust from being knocked down and scattering into the interior of the device.

[0035] When in use, the first filter screen 230 and the second filter screen 270 can effectively filter dust and impurities in the air. By starting the servo motor 210, the first reel-up shaft 220 is driven to rotate, so that the first reel-up shaft 220 reels the first filter screen 230, and the first filter screen 230 pulls the second filter screen 270 to move synchronously, so that the second filter screen 270 blocks the air inlet 110. By alternating the first filter screen 230 and the second filter screen 270, it is possible to effectively avoid clogging or damage caused by long-term operation of a single set of filters, thereby extending the overall service life of the filters. At the same time, the knocking rod 2960 knocks on the surfaces of the first filter screen 230 and the second filter screen 270, thereby The filter screen can be effectively removed from the dust, particulate matter and other impurities accumulated on the surface of the filter, thereby restoring its filtration efficiency, better capturing pollutants in the air, improving indoor air quality, and avoiding device performance degradation or failure due to blockage. When the rod 2920 rises, the fixed block 2930 will be flipped over by the action of the hinge, so that it will be disengaged from the straight groove 2921, thereby achieving reciprocating knocking. At the same time, two sets of arc-shaped partitions 2970 can isolate the position where the filter screen is knocked from the interior of the device to prevent dust from flying into the interior of the device when it falls. The fallen dust will be collected and processed in a centralized manner through the collection box 2980. The parts not involved in the device are the same as the existing technology or can be implemented using the existing technology.
