The air intake channel 16 is connected to the air inlets 12.
[0024] When in use, the fan 14 is turned on, and the fan 14 draws in air to form a negative pressure inside the inner liner 17. The air cavity is discharged from the air outlet, and the air intake channel 16 draws in air from the air inlet 12. The mesh plate 15 is installed inside the air intake channel 16 to intercept cat hair. The air filter 13 is used to filter dust particles. The mesh plate 15 is used to initially intercept cat hair, which can reduce the possibility of the filter being blocked, thus making it easier for staff to use.
[0025] Furthermore, such as Figure 1-5 As shown, the air intake channel 16 has a sliding groove 21 on its side. The sliding groove 21 is located on the side of the mesh plate 15. A seat 22 is slidably connected inside the sliding groove 21. A brush plate 23 is fixedly connected to the bottom of the seat 22. A spring is fixedly connected between the top of the seat 22 and the top side of the sliding groove 21. A pull rope 24 is fixedly connected to the seat 22.
[0026] In use, a groove 21 is provided on the side of the air intake channel 16. A seat 22 is slidably connected in the groove 21. A pull rope 24 is fixed on the seat 22. The pull rope 24 can be used to pull the seat 22 and the brush plate 23 to move downward. The brush plate 23 brushes away the cat hair on the mesh plate 15. A spring is used to reset the seat 22 upward.
[0027] Furthermore, such as Figure 1-5 As shown, a motor 33 is fixedly connected to the bottom of the inner liner 17, and a reel 34 is fixedly connected to the output end of the motor 33. The pull rope 24 is fixedly connected to the reel 34. A dust removal port 31 is provided on the bottom side of the shell 11. A dust collection tray 32 is slidably connected to the bottom of the shell 11. The dust collection tray 32 passes through the dust removal port 31 and is located at the bottom of the inner liner 17. A bracket 41 is fixedly connected to the bottom inner wall of the dust collection tray 32. A plate 42 is installed on the top of the bracket 41. A cleaning comb 43 is fixedly connected to the bottom of the plate 42 and is located below the slide groove 21. The plate 42 and the bracket 41 are rotatably connected by a pin. An elastic element 51 is fixedly connected to the bottom of the plate 42. The bottom end of the elastic element 51 is fixedly connected to the bracket 41. A limit seat 52 is fixedly connected to the top of the bracket 41 and at the corresponding position of the plate 42.
[0028] In use, relying on the dust removal port 31 opened at the bottom of the housing 11, the user can pull the dust collection tray 32 out from the dust removal port 31, which can be used to clean cat hair. The bottom of the inner liner 17 is equipped with a motor 33, and the output end of the motor 33 is fixed to the reel 34 for automatic winding of the pull rope 24, thereby causing the seat 22 to move down. The inside of the dust collection tray 32 is equipped with a bracket 41, and the top of the bracket 41 is equipped with a plate 42. The plate 42 is equipped with a cleaning comb 43. After the brush moves down, its brush contacts the cleaning comb 43 to comb the cat hair on the brush and achieve the cleaning effect.
[0029] Furthermore, the plate 42 is rotatably connected to the bracket 41 via a pin. An elastic element 51 is installed between the bottom of the plate 42 and the bracket 41 to support the plate 42. During the downward movement of the brush, it will squeeze the cleaning comb 43 and the plate 42 to rotate downward, thus avoiding collisions. When moving upward, the brush bristles cooperate with the cleaning comb 43 to clean the cat hair trapped in the brush. The limiting seat 52 is set above the plate 42 to limit it, thereby keeping the plate 42 in an inclined state.
[0030] Furthermore, such as Figure 1-5 As shown, a perforated plate 6 is fixedly attached to the air inlet 12. In use, the perforated plate 6 is used to block the air inlet 12, which serves to prevent foreign objects from entering and for decorative purposes.
[0031] Working principle: When in use, the fan 14 is turned on, and the fan 14 draws in air, creating a negative pressure inside the inner liner 17. The air is discharged from the outlet. The air intake channel 16 draws in air from the inlet 12. A mesh plate 15 is installed inside the air intake channel 16 to intercept cat hair. The air filter 13 is used to filter dust particles. The mesh plate 15 provides initial interception of cat hair, which reduces the chance of the filter being clogged, making it easier for staff to use. During use, a sliding groove 21 is provided on the side of the air intake channel 16. A seat 22 is slidably connected in the sliding groove 21. A pull rope 24 is fixed on the seat 22. The pull rope 24 can be used to pull the seat 22 and the brush plate 23 downwards. 23 brushes away cat hair on the mesh plate 15, and the spring is used to reset the seat 22 upwards; in use, relying on the dust removal port 31 opened at the bottom of the housing 11, the user can pull the dust collection tray 32 from the dust removal port 31 to move and pull it out, which can be used to clean cat hair. The bottom of the inner liner 17 is equipped with a motor 33, and the output end of the motor 33 is fixed to the reel 34 for automatic winding of the pull rope 24, thereby causing the seat 22 to move down. The dust collection tray 32 is equipped with a bracket 41, and the top of the bracket 41 is equipped with a plate 42. The plate 42 is equipped with a cleaning comb 43. After the brush moves down, its brush contacts the cleaning comb 43 to comb the cat hair on the brush and play a cleaning role.
[0032] Furthermore, the plate 42 is rotatably connected to the bracket 41 via a pin. An elastic element 51 is installed between the bottom of the plate 42 and the bracket 41 to support the plate 42. During the downward movement of the brush, it will squeeze the cleaning comb 43 and the plate 42 downward to rotate, thus avoiding collisions. When moving upward, the brush bristles cooperate with the cleaning comb 43 to clean the cat hair trapped in the brush. The limiting seat 52 is set above the plate 42 to limit it, thereby keeping the plate 42 in an inclined state. The perforated plate 6 is used to cover the air inlet 12, which serves to prevent foreign objects from entering and for decoration.
