[0028] In this embodiment: an air inlet slot 14 is opened on one side of the chassis 1, the air inlet end of the fan 2 is connected to the air inlet slot 14, a blocking plate 7 for blocking the air inlet slot 14 is provided in the chassis 1, and an electric push rod 15 is fixedly connected to the top of the chassis 1, and the output end of the electric push rod 15 passes through the chassis 1 and is fixedly connected to the blocking plate 7.

[0029] The blocking plate 7 cooperates with the electric push rod 15 to realize the lifting function in the chassis 1. When the filter 3 needs to be self-cleaned, the blocking plate 7 can be lowered and blocked on one side of the air inlet slot 14, so that the dust scraped off the filter 3 will not spread outward through the air inlet slot 14.

[0030] In this embodiment: an air outlet slot 6 is provided on the other side of the chassis 1 , and a guide plate 10 is fixedly connected to the air outlet slot 6 .

[0031] When the temperature-controlled air passes through the air outlet slot 6 , the guide plate 10 can provide a guide function for the flowing air. In the utility model, a plurality of guide plates 10 can be vertically arranged in the air outlet slot 6 .

[0032] In this embodiment: a driving structure 8 is provided on the chassis 1, and the driving structure 8 includes a screw rod 81, which is rotatably connected in the chassis 1, and a threaded seat 82 is threadedly connected to the screw rod 81. A rotating motor 83 is fixedly connected to one end of the chassis 1, and the output end of the rotating motor 83 passes through the chassis 1 and is fixedly connected to one end of the screw rod 81. A smooth rod 84 is fixedly connected in the chassis 1, and the threaded seat 82 is slidably connected to the smooth rod 84.

[0033] The screw rod 81 is driven to rotate by the rotary motor 83 , and the threaded seat 82 can move linearly on the screw rod 81 under the effect of the smooth rod 84 providing a linear guide for the threaded seat 82 .

[0034] In this embodiment: a scraper 9 is provided on the driving structure 8, and the scraper 9 is in active contact with the dust filtering surface of the filter screen 3.

[0035] The scraper 9 utilizes the linear mobility of the threaded seat 82 to perform linear scraping on the dust filtering surface of the filter screen 3, so that the dust on the dust filtering surface of the filter screen 3 can be scraped off and fall down to settle freely.

[0036] In this embodiment: the threaded seat 82 is fixedly connected to a mounting plate 16 , the mounting plate 16 is fixedly connected to a spring telescopic rod 17 , and the scraper 9 is fixedly connected to one end of the spring telescopic rod 17 .

[0037] The spring telescopic rod 17 is composed of a spring and a telescopic rod. The scraper 9 is arranged with the spring telescopic rod 17 and the mounting plate 16, so that the scraper 9 can improve the fit when it contacts the filter screen 3.

[0038] In this embodiment: a dust collecting groove 12 is provided at the bottom of the chassis 1 .

[0039] The dust collecting chute 12 is provided to facilitate the passage of freely settled dust.

[0040] In this embodiment: a dust collecting structure 11 connected to a dust collecting groove 12 is provided at the bottom of the chassis 1, and the dust collecting structure 11 includes a dust collecting hopper 111, the dust collecting hopper 111 is fixedly connected to the bottom of the chassis 1, and the dust collecting hopper 111 is connected to the dust collecting groove 12, and a drawer box 112 is slidably connected in the dust collecting hopper 111.

[0041] In the present invention, the dust collecting hopper 111 is arranged in an upper opening structure, so the dust passing through the dust collecting groove 12 can enter the drawer box 112, and by utilizing the sliding effect of the drawer box 112 and the dust collecting hopper 111, the drawer box 112 can be conveniently cleaned by a quick pulling method.

[0042] In this embodiment: a dust shield structure 13 is provided on the chassis 1, and the dust shield structure 13 extends into the dust collecting groove 12. The dust shield structure 13 includes a winding assembly and a dust shield cloth 134. The winding assembly includes a reel box 131, and the reel box 131 is fixedly connected to one end of the chassis 1. A cloth drum 132 is rotatably connected inside the reel box 131. A spiral spring 133 is provided on the cloth drum 132 and the reel box 131. The dust shield cloth 134 is wound on the cloth drum 132, and one end of the dust shield cloth 134 passes through the chassis 1 and extends into the dust collecting groove 12.

[0043] The spiral spring 133 can give the cloth drum 132 in the drum box 131 a rotatable effect so as to realize the automatic reeling of the dust shield 134, and the dust shield 134 can be used to flexibly block the dust collecting groove 12. When the filter 3 is self-cleaning, the dust shield 134 can open the dust collecting groove 12 so that dust can pass through the dust collecting groove 12. Similarly, when the dust shield 134 blocks the dust collecting groove 12, the horizontal fan coil unit is in a ventilation state.

[0044] In this embodiment: one end of the dust shield cloth 134 is fixedly connected to a slide plate 18, and the slide plate 18 is slidably connected in the dust collecting groove 12. A pull rope 19 is fixedly connected to the slide plate 18. The other end of the screw rod 81 is fixedly connected to a rope drum 20. The rope drum 20 is located at the other end of the chassis 1. One end of the pull rope 19 passes through the chassis 1 and is wound around the rope drum 20.

[0045] During use, the rotation of the screw rod 81 drives the scraper 9 to self-clean the filter 3. At this time, the rope drum 20 can unwind the pull rope 19. The spiral spring 133 in the tensioned state can drive the cloth drum 132 to rotate, so that the cloth drum 132 can rewind the dust shield cloth 134, and the dust collection groove 12 can be opened by the retracted dust shield cloth 134, so that the dust scraped off the filter 3 can enter the drawer box 112.

[0046] When the scraper 9 makes a return stroke, the screw rod 81 reverses, and the reversed screw rod 81 can drive the rope drum 20 to wind the pull rope 19, so that the pull rope 19 can pull the slide plate 18 to slide in the dust collecting groove 12. The cross-section of the dust collecting groove 12 is arranged in a "cross" shape, until the slide plate 18 abuts against one end of the dust collecting groove 12. At this time, the dust blocking cloth 134 connected to the slide plate 18 can block the dust collecting groove 12, thereby closing the connection between the dust collecting structure 11 and the chassis 1.

[0047] In this embodiment, a guide roller 21 is provided at the other end of the chassis 1 , and the pull rope 19 is movably connected to the guide roller 21 .

[0048] The guide roller 21 can provide rolling support for the pull rope 19 .

[0049] In this embodiment, a second scraper 22 is fixedly connected in the dust collecting groove 12 , and the second scraper 22 is slidably connected to the upper surface of the dust shielding cloth 134 .

[0050] Because the dust shield cloth 134 is only opened when the scraper 1 9 is scraping the filter 3, in order to avoid dust accumulation on the upper surface of the dust shield cloth 134, the scraper 2 22 can cooperate with the cloth tube 132 to scrape the upper surface of the dust shield cloth 134 during the process of rolling up the dust shield cloth 134, which can improve the thoroughness of dust cleaning.

[0051] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model should be included in the protection scope of the present utility model.
