[0026] In summary, due to the adoption of the above technical solutions, the beneficial effects of the present invention are as follows:

[0027] 1. In the present invention, through the provided adaptive hair removal component, when the clothes are placed inside the drying cylinder, the driving unit drives the drying cylinder to rotate. The PTC fan unit will convey the heated air to the inside of the drying cylinder through the pipeline, fixed frame, air outlet, air distribution seat and equalizing plate for drying. During the rotation of the clothes, the pet hair and shed fibers lifted by the clothes will come into contact with the hair-catching seat. The hair-catching seat can directly adsorb large-particle impurities such as the shed fibers and pet hair of the clothes, reduce the pollutants entering the filter screen and air duct, and reduce the load of the main filtration system. When the air supply unit of the PTC fan unit is larger, the gas pressure at the bottom side inside the fixed frame will drive the second piston to move upward and squeeze the liquid sac and the third spring, leaking out more air outlets. The liquid inside the liquid sac will be conveyed to the inside of the arc-shaped frame through the connecting pipe, infusion channel and connecting through hole, so that the first piston drives the connecting block and the conical block to move, so that the first roller drives the hair-catching seat to move away from the outside of the arc-shaped frame, further improving the adhesion and capture effect of the hair-catching seat on the pet hair and shed fibers inside the drying cylinder. By setting the hair-catching seat with adaptive wind speed, in the process of low wind speed, a small-area hair-catching seat can effectively capture a small amount of fibers, avoiding rapid attenuation of its performance due to excessive adsorption. At high wind speed, the use area of the hair-catching seat is automatically expanded, enabling it to match a larger air flow and fluff amount, so that the hair-catching seat can capture more pet hair and shed fibers per unit time, preventing the escape of pet hair and shed fibers caused by too high wind speed. Furthermore, it helps to reduce the blockage phenomenon of the equipment during subsequent use, reduces the cleaning frequency, and effectively improves the operation stability of the equipment during use.

[0028] 2. In the present invention, through the provided air flow backwashing component, when some pet hair and shed fibers carried by the humid and hot air enter the coarse filter screen and cause it to become blocked, when the wind force at the top of the coarse filter screen gradually becomes greater than the opening value of the elastic valve piece, the elastic valve piece will be opened. At this time, the control unit will energize the second electromagnet and drive the sliding plate to move away from the elastic valve piece through the first electromagnet. The wind force at the side air outlet will further improve its response speed. During the movement of the sliding plate, the sliding plate will drive the gear to rotate rapidly through the rack, and the gear will drive the ratchet pawl, fixed seat, fixed shaft and coarse filter screen to rotate through the ratchet groove opened inside it, so as to quickly rotate the coarse filter screen by 180 degrees. After that, the wind force of the air flow will assist in impacting the surface of the coarse filter screen from above to backwash the blocked pet hair and shed fibers at the bottom of the coarse filter screen. Through dynamic cleaning, this device can avoid the gradual blockage of the pores of the coarse filter screen, maintain a stable air flow passing rate, prevent the drying efficiency from decreasing or the overheat protection from shutting down due to filter screen blockage, effectively improve the continuity and stability of the equipment during use, and thus ensure the overall applicability of the equipment during use.

[0029] 3. In the present invention, through the vibration assembly provided, the lower coarse filter screen will squeeze the second roller during rotation, causing the second roller to drive the limiting rod and the fine filter screen to move downward, and under the action of the fourth spring, the fine filter screen will continuously move up and down, enabling pet hair and shed fibers to concentrate and accumulate on one side of the top of the fine filter screen for subsequent centralized treatment. Moreover, the vibration of the fine filter screen helps reduce the caking of fibers on its surface, assisting in ensuring the ventilation effect during the use of the fine filter screen, thereby effectively improving the overall performance of the device.

One side of the first roller 309 is fixedly connected to the hair sticking seat 310 through a fixing block. Both the hair sticking seat 310 and the fixing block are slidably connected inside the arc-shaped frame 305. On both sides of the fixing block, there are second springs 313, and both sides of the second spring 313 are respectively fixedly connected to one side of the hair sticking seat 310 and the inner wall of the arc-shaped frame 305. On both sides of the connecting block 307, there are first springs 312, and both sides of the first spring 312 are respectively fixedly connected to one side of the partition and the inner wall of the arc-shaped frame 305. One side of the circular frame 303 is communicated with a liquid sac 315 through a connecting pipe 314. There is a fixing frame 318 on the outer peripheral side of the liquid sac 315, and the top of the liquid sac 315 is fixedly connected to the inner wall of the fixing frame 318. One side of the fixing frame 318 is fixedly connected to the inner wall of the air delivery base 301. The bottom of the liquid sac 315 is fixedly connected to a second piston 316. On both sides of the liquid sac 315, there are third springs 317, and both sides of the third spring 317 are respectively fixedly connected to one side of the second piston 316 and the inner wall of the fixing frame 318. On both sides of the bottom of the fixing frame 318, there are a plurality of air outlets 319. One side of the housing 1 is rotatably sealed with a flip door through a hinge. On one side inside the housing 1, there is a cavity, and the cavity is arranged on the side opposite to the flip door. The filter box 4 is arranged inside the cavity and is arranged on the side away from the air delivery base 301. On the bottom side inside the housing 1, there is a heat generating unit, and the heat generating unit can be composed of a condenser, an evaporation unit, and a compressor. On one side below the drying cylinder 2, there is a PTC fan unit 9. The PTC fan unit 9 is arranged on the side away from the filter box 4 and is fixedly connected inside the housing 1. One side of the PTC fan unit 9 is connected to the fixing frame 318 through a pipeline.Above the PTC fan unit 9, there is a support unit 11. The support unit 11 is arranged on the outer peripheral side of the drying cylinder 2. On one side of the support unit 11, there is a drive unit 10 for driving the drying cylinder 2 to rotate. On one side of the drive unit 10, there are a control unit 12 and a wind guide box 13. The drive unit 10, the control unit 12 and the wind guide box 13 are all connected inside the housing 1, and the wind guide box 13 is communicated with the cavity inside the housing 1.,

[0046] Specific implementation method: First, place the device in a suitable place. Then, open the flip door and place the clothes inside the drying cylinder 2. Drive the drying cylinder 2 to rotate through the drive unit 10 so that the clothes inside it rotate evenly. The PTC fan unit 9 will transport the heated air to the inside of the fixed frame 318 through a pipeline. When the air supply unit of the PTC fan unit 9 is larger, the wind force transported to the inside of the fixed frame 318 is greater. At this time, the gas pressure at the bottom side inside the fixed frame 318 will drive the second piston 316 to move upward and squeeze the liquid sac 315 and the third spring 317, leaking out more air outlets 319. At this time, the heated gas will be evenly transported to the drying channel inside the drying cylinder 2 through the air delivery seat 301 and the equalizing plate 302 to dry the clothes. During the rotation of the clothes, the pet hair and shed fibers raised by them will come into contact with the hair-catching seat 310. The hair-catching seat 310 can directly adsorb large particle impurities such as the fibers and pet hair shed by the clothes, reduce the pollutants entering the filter screen and the air duct, and reduce the load of the main filtration system. At this time, the liquid inside the liquid sac 315 will be transported to the inside of the arc-shaped frame 305 through the connecting pipe 314, the infusion channel and the connecting through hole. As the liquid on one side inside the arc-shaped frame 305 increases, it will cause the first piston 306 to drive the connecting block 307 and the tapered block 308 to move. During the movement of the tapered block 308, it will squeeze the first roller 309, causing the first roller 309 to drive the hair-catching seat 310 to move away from the outside of the arc-shaped frame 305, further improving the adhesion and capture effect of the hair-catching seat 310 on the pet hair and shed fibers inside the drying cylinder 2, assisting in reducing the blockage phenomenon of the device during subsequent use, reducing the cleaning frequency, and effectively improving the operation stability of the device during use. And it assists in reducing the blockage of the air duct by fiber clusters, ensuring the uniform distribution of hot air, avoiding local overheating or non-drying phenomenon. The humid and hot air inside the drying cylinder 2 will be transported to the inside of the wind guide box 13 through the cavity and the filter box 4 opened inside it, and then transported to the heat generating unit through the wind guide box 13. After being processed by the heat generating unit, it is transported to the inside of the drying cylinder 2 again through the PTC fan unit 9, the pipeline, the air delivery seat 301 and the equalizing plate 302 to improve the heat circulation effect and drying effect inside the drying cylinder 2.,

[0047] The air flow recoil assembly 5 includes a plurality of sliding plates 502 and a plurality of inner cavities 501. The sliding plates 502 are slidably connected inside the inner cavities 501. One side of the bottom of the inner cavity 501 is communicated with a side exhaust port, and the side exhaust port is arranged on one side opposite to the sliding plate 502. Both the inner cavity 501 and the side exhaust port are arranged at the central position of the filter box 4. Filter inner cavities are formed on both sides inside the filter box 4. Two coarse filter meshes 7 and one fine filter mesh 8 are sequentially arranged from top to bottom inside the filter inner cavity. The cross section of the fine filter mesh 8 is arranged obliquely. Elastic valve pieces 503 are fixedly connected to both sides of the sliding plate 502. One side of the elastic valve piece 503 is fixedly connected to the inner wall of the filter box 4. A first electromagnet is arranged on the side of the sliding plate 502 away from the elastic valve piece 503. A second electromagnet is arranged on the other side of the first electromagnet. The other side of the second electromagnet is fixedly connected to the inner wall of the filter box 4. A rack 504 is arranged below the elastic valve piece 503. One side of the bottom of the rack 504 is meshed with a gear 505. One side of the gear 505 is rotatably connected to the filter box 4 through a connecting shaft. A ratchet groove is formed inside the gear 505. A round wheel 506 is arranged inside the ratchet groove. A fixed shaft 508 is fixedly connected to the side of the round wheel 506 away from the gear 505. Opposite ends of the two fixed shafts 508 extend into the filter inner cavity and are fixedly connected to the outer wall of the coarse filter mesh 7. A limiting device is sleeved on the outer peripheral side of the fixed shaft 508, and the limiting device is arranged inside the filter box 4. A fixed seat is fixedly connected to the outside of one side of the round wheel 506. A limiting spring is fixedly connected to the top of the fixed seat. A pawl 507 is fixedly connected to the top of the limiting spring.

[0048] Specific implementation manner: The coarse filter screen 7 and the fine filter screen 8 filter the humid and hot air entering the interior of the filter box 4. When some pet hairs and shed fibers carried by the humid and hot air enter the coarse filter screen 7, the coarse filter screen 7 will gradually become blocked. As the coarse filter screen 7 becomes blocked, the wind pressure on the top side inside the filter box 4 becomes greater. When the wind force is greater than the opening value of the elastic valve piece 503, the side air outlet will suddenly open and the air will be conveyed through it to the lower coarse filter screen 7 and fine filter screen 8 for filtration. At this time, the control unit 12 will energize the second electromagnet, and the second electromagnet will drive the sliding plate 502 to move away from the elastic valve piece 503 through the first electromagnet. The wind force at the side air outlet will further increase its response speed. During the movement of the sliding plate 502, the sliding plate 502 will quickly drive the rack 504 to move, the rack 504 will drive the gear 505 to rotate, and the gear 505 will drive the pawl 507, the fixed seat and the fixed shaft 508 to rotate through the ratchet groove opened inside it, so that the fixed shaft 508 quickly drives the coarse filter screen 7 to rotate, so as to quickly turn over the coarse filter screen 7. After the turnover is completed, the wind force of the air flow will assist in cleaning the surface of the coarse filter screen 7 to reduce the impurity residue on the coarse filter screen 7, improve the self-cleaning effect of the device during use, effectively improve the continuity and stability of the device during use, and then ensure the overall applicability of the device during use. According to needs, the opening value of the lower elastic valve piece 503 is made smaller than the opening value of the upper elastic valve piece 503 to ensure the opening stability of the lower elastic valve piece 503.

[0049] The vibration assembly 6 includes a mounting plate 601. The mounting plate 601 is arranged below the coarse filter screen 7, and one side of the mounting plate 601 is fixedly connected to the inner wall of the filter box 4. A limiting rod 602 is slidably connected inside the mounting plate 601. The top end of the limiting rod 602 is fixedly connected to a second roller 604. The bottom end of the limiting rod 602 is fixedly connected to the top of the fine filter screen 8. A fourth spring 603 is sleeved on the outer peripheral side of the limiting rod 602. The two sides of the fourth spring 603 are respectively fixedly connected to the bottom of the mounting plate 601 and the top of the fine filter screen 8.

[0050] Specific implementation manner: During the rotation of the lower coarse filter screen 7, the lower coarse filter screen 7 will squeeze the second roller 604, so that the second roller 604 drives the limiting rod 602 and the fine filter screen 8 to move downward, and under the action of the fourth spring 603, the fine filter screen 8 continuously moves up and down, so that pet hairs and shed fibers are concentrated and piled up on one side of the top of the fine filter screen 8 for subsequent centralized treatment, and it also helps to reduce the blockage phenomenon of the fine filter screen 8 during use and improves the overall performance of the device.

[0051] Working principle: When in use, first place the device in a suitable place. Then, open the flip door and place the clothes inside the drying cylinder 2. The driving unit 10 drives the drying cylinder 2 to rotate, so that the clothes inside it rotate evenly. The PTC fan unit 9 conveys the heated air to the inside of the fixed frame 318 through a pipeline. When the air supply unit of the PTC fan unit 9 is larger, the wind force conveyed to the inside of the fixed frame 318 is greater. At this time, the gas pressure at the bottom side inside the fixed frame 318 drives the second piston 316 to move upward and squeeze the liquid sac 315 and the third spring 317, leaking out more air outlets 319. At this time, the heated air will be evenly conveyed to the drying channel inside the drying cylinder 2 through the air supply seat 301 and the equalizing plate 302 to dry the clothes. The lint-catching seat 310 can directly adsorb large particle impurities such as fibers shed from clothes and pet hairs. At this time, the liquid inside the liquid sac 315 will be conveyed to the inside of the arc-shaped frame 305 through the connecting pipe 314, the infusion channel and the connecting through hole. As the liquid on one side inside the arc-shaped frame 305 increases, it will cause the first piston 306 to drive the connecting block 307 and the conical block 308 to move. During the movement of the conical block 308, it will squeeze the first roller 309, causing the first roller 309 to drive the lint-catching seat 310 to move away from the outside of the arc-shaped frame 305, further improving the adhesion and capture effect of the lint-catching seat 310 on pet hairs and shed fibers inside the drying cylinder 2;

[0052] The humid and hot air inside the drying cylinder 2 will be conveyed to the inside of the air guide box 13 through the cavity and the filter box 4 opened inside it, and then conveyed to the inside of the heat generating unit through the air guide box 13. After being processed by the heat generating unit, it is conveyed to the inside of the drying cylinder 2 again through the PTC fan unit 9, the pipeline, the air supply seat 301 and the equalizing plate 302 to improve the heat circulation effect and drying effect inside the drying cylinder 2;

[0053] The coarse filter screen 7 and the fine filter screen 8 filter the humid and hot air entering the interior of the filter box 4. When some pet hairs and shed fibers carried by the humid and hot air enter the coarse filter screen 7, the coarse filter screen 7 will gradually become blocked. As the coarse filter screen 7 becomes blocked, the wind pressure on the top side inside the filter box 4 becomes greater. When the wind force is greater than the opening value of the elastic valve piece 503, the side air outlet will suddenly open and the air will be conveyed through it to the lower coarse filter screen 7 and fine filter screen 8 for filtering. At this time, the control unit 12 will energize the second electromagnet, and the second electromagnet will drive the sliding plate 502 to move away from the elastic valve piece 503 through the first electromagnet. During the movement of the sliding plate 502, the sliding plate 502 will quickly drive the rack 504 to move, and the rack 504 will drive the gear 505 to rotate. The gear 505 will drive the pawl 507, the fixed seat and the fixed shaft 508 to rotate through the ratchet groove opened inside it, so that the fixed shaft 508 will quickly drive the coarse filter screen 7 to rotate to quickly turn over the coarse filter screen 7. After the turning over is completed, the wind force of the air flow will assist in cleaning the surface of the coarse filter screen 7, and impurities such as pet hairs and shed fibers will be conveyed to the lower coarse filter screen 7 under the action of the wind force. When the coarse filter screen 7 becomes blocked, the lower elastic valve piece 503 will quickly open and turn over the lower coarse filter screen 7 and convey it into the fine filter screen 8;

[0054] During the rotation of the lower coarse filter screen 7, it will squeeze the second roller 604, causing the second roller 604 to drive the limit rod 602 and the fine filter screen 8 to move downward, and under the action of the fourth spring 603, the fine filter screen 8 will continuously move up and down, so that pet hairs and shed fibers will accumulate concentratedly on one side of the top of the fine filter screen 8 for subsequent centralized treatment. After the second electromagnet is energized for the set time, the second electromagnet will be de-energized. As the coarse filter screen 7 is unblocked, the wind force at the side air outlet will become smaller and smaller, and the elastic valve piece 503 will drive the sliding plate 502 to reset. During the process of the sliding plate 502 driving the rack 504 to reset, due to the action of the pawl 507 and the ratchet tooth groove, the gear 505 will not drive the round wheel 506 to rotate through the pawl 507 to ensure the stable use state of the coarse filter screen 7.
