Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0020] like Figure 1-4 As shown, the utility model proposes an air handler for a central air-conditioning system, comprising an air handling case 1, a dust removal port 18 is penetrated on the bottom wall of the air handling case 1, a dust collecting groove 2 is embedded in the bottom of the air handling case 1, an air inlet pipe 1 3 is penetrated on the side wall of the air handling case 1, an air inlet pipe 2 4 is provided on the same side of the air inlet pipe 1 3, and the air inlet pipe 2 4 penetrates the air handling case 1, an exhaust fan blade 5 is provided at one end of the air handling case 1 away from the air inlet pipe 1 3 and the air inlet pipe 2 4, a rolling curtain shielding component 6 is provided on the air handling case 1, a horizontal dust removal component 7 is provided in the air handling case 1, and the horizontal dust removal component 7 is arranged directly above the dust collecting groove 2, a filter 1 8 and a filter 2 9 are provided in the air handling case 1, the filter 1 8 and the filter 2 9 separate the horizontal dust removal component 7 from the air inlet pipe 1 3 and the air inlet pipe 2 4, and the filter 1 8 is arranged between the air inlet pipe 1 3 and the filter 2 9.

[0021] like Figure 1-4As shown, the horizontal dust removal assembly 7 includes a dust removal motor 10, a dust removal adjustment screw 11, a dust removal adjustment slide bar 12 and a dust removal rotation roller 13. The dust removal motor 10 is arranged on the inner wall of the air handling chassis 1. The dust removal adjustment screw 11 is arranged on the output shaft of the dust removal motor 10 and rotates in the air handling chassis 1. The filter screen 9 is arranged between the filter screen 8 and the dust removal adjustment screw 11. The dust removal adjustment screw 11 is arranged between the filter screen 9 and the exhaust fan blade 5. The dust removal motor 10. The dust removal adjustment screw 11, the dust removal port 18 and the dust collecting tank 2 are in the same horizontal plane. The dust removal adjustment slide bar 12 is arranged in the air handling unit case 1 and is parallel to the bottom of the dust removal motor 10. One end of the dust removal self-rotating roller 13 is threadedly connected to the dust removal adjustment screw 11, and the other end of the dust removal self-rotating roller 13 is slidably connected to the dust removal adjustment slide bar 12. A plurality of groups of dust removal brushes 17 are arranged in a circular array on the dust removal self-rotating roller 13, and the dust removal self-rotating roller 13 is arranged in a self-rotating roller body.

[0022] like Figure 1-4 As shown, the rolling shutter shielding assembly 6 includes a rolling shutter baffle 14, a hanging ring 15 and a hook 16. The rolling shutter baffle 14 rotates on the air handling case 1, the hanging ring 15 is arranged on the rolling shutter baffle 14, and the hook 16 is arranged on the air handling case 1.
