A hair-collecting part 6 is provided on 501, and a hair-scraping tooth 7 is provided at the intersection of the hair-collecting surface 501 and the sliding surface 502; at least one hair-collecting part 5 has a hair-suction port 503 near its end on the hair-collecting surface 501; the hair-suction port 503 is connected to the inlet of the negative pressure device 10; the adjusting ring 8 is rotatably arranged relative to the bracket 4, and the adjusting ring 8 cooperates with each hair-collecting part 5 through multiple sliding grooves to drive each hair-collecting part 5 to contract or open synchronously, and a rotation drive mechanism is provided between the adjusting ring 8 and the bracket 4; the end panel is provided at the front end of the bracket and fastens multiple hair-collecting parts inside, and the end panel 9 is provided with an inlet 901, which is axially aligned with the pet passage and the ring opening 401.

[0053] refer to Figure 6 , Figure 8 , Figure 9 and Figure 15The structure of the bracket 4, the various collecting components 5, and the adjusting ring 8 in the automatic lint collection and suction device is similar to that of a shutter mechanism. Multiple rollers 403 are arranged inside the bracket 4, and a rolling ring 802 is arranged on one side of the adjusting ring 8. The surfaces of each roller 403 can roll along the surface of the rolling ring 802, allowing the adjusting ring 8 to roll relative to the bracket 4. A negative pressure pipe 11 connects the collecting component 5 with the suction port 503 to the inlet of the negative pressure device 10. The negative pressure pipe 11 can be a flexible pipe capable of bearing pressure, such as a corrugated pipe or a spring pipe.

[0054] refer to Figure 3 , Figure 4 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 The automatic hair collection and suction device is located at the entrance of the litter box. When the eight hair collection components 5 are slid into the pet passage open position, the cat will inevitably pass through the entrance / exit 901, the pet passage, and the enclosure 401 when entering or exiting the litter box. At this time, the cat's fur will come into contact with the hair collection parts 6 on the collection surfaces 501 of each hair collection component 5, and the shed pet hair will be collected on each collection part 6. Then, the rotation drive mechanism is activated, which drives the adjusting ring 8 to rotate. The adjusting ring 8 moves the eight hair collection components 5, causing the pet passage to close. The pet passage narrows as eight hair-collecting components 5 slide synchronously on the support 4. The scraping teeth 7 on each hair-collecting component 5 scrape the hair-collecting parts 6 on adjacent hair-collecting components 5 until the pet passage opening shrinks to the set size. At this point, the scraping teeth 7 on each hair-collecting component 5 have scraped the pet hair to the suction port 503. Then, the negative pressure device 10 is activated. The negative pressure device 10 sucks away the scraped pet hair through the suction port 503 and the negative pressure pipeline 11. After the pet hair is sucked away, the negative pressure device 10 stops, and the adjusting ring 8 moves the eight hair-collecting components 5 to open the pet passage to its original size.

[0055] Example 5

[0056] refer to Figure 7 and Figure 14 Based on embodiment 4, the hair collecting surface 501 on one of the hair collecting components 5 is a smooth surface, and the smooth surface slides and adheres to the sliding surface 502 on the hair collecting component 5 with the hair suction port 503.

[0057] Since the suction port 503 is provided on the sliding surface 502 of the hair collecting component 5, the hair scraping teeth 7 cannot be provided, and therefore the hair collecting surface 501 on the adjacent hair collecting component 5 cannot be scraped. Therefore, the hair collecting surface 501 on the adjacent hair collecting component 5 does not need to be provided with the hair collecting part 6, and a smooth surface is used directly.

[0058] Example 6

[0059] refer to Figure 7 , Figure 10 and Figure 11 Based on embodiment 4, the hair collection part 6 is a comb tooth, and correspondingly, the sliding surface 502 of the multiple hair collection parts 5 is provided with a groove 504, and the hair scraping tooth 7 is provided at one end of the groove 504. The comb tooth and the hair scraping tooth 7 are distributed alternately.

[0060] The hair collection part 6 uses multiple rows of comb teeth, which are set on the hair collection surface 501 of the hair collection part 5. The sliding surface 502 of the adjacent hair collection part 5 is provided with a groove 504, which can accommodate the comb teeth when the pet passage is contracted. When the pet passes through the ring 401 and the pet passage, the multiple rows of comb teeth will comb the pet's fur, and the pet's shed fur will be combed off by the comb teeth. The comb teeth and the scraping teeth 7 are distributed alternately. When the pet passage is contracted, two adjacent hair collection parts 5 slide against each other, and the scraping teeth 7 pass through the spaces between the multiple rows of comb teeth, which can scrape away the pet fur between the comb teeth.

[0061] Example 7

[0062] refer to Figure 4 and Figure 5 Based on embodiment 4, the rotation drive mechanism includes a motor 12, and a gear set or pulley set is provided between the main shaft of the motor 12 and the adjusting ring 8 to drive the adjusting ring 8 to rotate.

[0066] When the adjusting ring 8 rotates under the drive of the rotating mechanism, the multiple second inclined grooves 801 on the adjusting ring 8 push one end of the guide post 505 on the hair collection component 5, so that the hair collection component 5 moves along the first inclined groove 402 on the bracket 4 through the other end of the guide post 505. At the same time, each pair of adjacent hair collection components 5 slides against each other through the hair collection surface 501 and the sliding surface 502, so as to realize the adjustment of the size of the pet passage, so that the whole device can adapt to pet cats of different sizes.

[0067] Example 9

[0068] refer to Figure 4 , Figure 5 , Figure 8 and Figure 16 Based on any of the above embodiments, a controller 16 is also included. The two signal output terminals of the controller 16 are electrically connected to the rotation drive mechanism and the negative pressure device 10, respectively, for controlling the drive mechanism to drive the adjustment ring 8 to rotate, so that the negative pressure device 10 can suck up hair through the negative pressure pipeline 11 and the hair suction port 503.

[0069] Two of the signal output terminals of the controller 16 are electrically connected to the negative pressure device 10 and the motor 12 in the rotation drive mechanism, respectively. The controller 16 can control the start and stop of the motor 12 and the negative pressure device 10, and can control the rotation drive mechanism to drive the adjusting ring 8 to rotate, so that the shaving teeth 7 shave the hair on each hair collection part 6, and at the same time, the negative pressure device 10 sucks away the pet hair shaving teeth 7 from each hair collection part 6 through the suction port 503.
