[0035] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0036] like Figure 1-5 As shown, a low-noise cabinet-type fan coil unit includes a cabinet 1, a coil assembly 2, a rotating shaft 3, fan blades 4, a motor 5, and a filter mechanism. The cabinet 1 has an air inlet 11 at the bottom and an air outlet 12 at the top. Air guide plates 13 are fixedly and inclined on both sides of the cabinet, and the air guide plates are arranged corresponding to the air inlet and the air outlet. The coil assembly 2 is fixed to the inner wall of the cabinet. A fixing sleeve 51 is fixed to the outer wall of the motor 5, and a connecting plate 52 is fixed to the outer wall of the fixing sleeve 51. The end of the connecting plate is fixed to the inner wall of the cabinet. The rotating shaft 3 is connected to the output shaft of the motor. The fan blades 4 are fixed to the rotating shaft.

[0037] Specifically, the filtration mechanism includes a filter plate 61, a connecting shaft 62, a cleaning brush 63, a slider 64, a pull rod 65, and connecting components. The filter plate 61 has evenly spaced filter holes and is fixed to the inner wall of the air inlet. A sliding groove 111 is provided on the inner wall of the air inlet. The slider 64 is located in the sliding groove and can slide relative to the sliding groove. The two ends of the connecting shaft 62 are connected to the slider through connecting components. The cleaning brush 63 is fixed on the connecting shaft and contacts the filter plate. One end of the pull rod 65 is fixed to the slider, and the other end extends out of the cabinet. The filter plate can filter the air passing through the air inlet. When a lot of impurities accumulate on the filter plate, the slider can be pulled outward by the pull rod, which will move the cleaning brush off the filter plate, thereby clearing the filter holes and ensuring the ventilation efficiency of the filter plate.

[0038] As a preferred embodiment, the connecting assembly includes a mounting groove 661, a slide rod 662, a connecting block 663, and an elastic element 664. The mounting groove 661 is formed on the side wall of the slider; both ends of the slide rod 662 are fixed to the inner wall of the mounting groove; the connecting block 663 is provided on the slide rod and can slide up and down relative to the slide rod, and one end of the connecting shaft is connected to the connecting block; the elastic element 664 is a spring, which is sleeved on the slide rod, and one end of it is fixed to the connecting block, and the other end is fixed to the side wall of the mounting groove. By pushing the connecting block down through the elastic element, it can be ensured that the cleaning brush fits against the filter plate, so that the bristles of the cleaning brush can enter the filter holes for unblocking.

[0039] In other embodiments, the filtration mechanism further includes a dust collection box 671, a collection box 672, a handle 673, a sealing plate 674, a rotating shaft 675, a reset component 676, a connecting rod 677, an elastic telescopic rod 678, and a ball bearing 679. The filter plate 61 has a dust discharge port 611. The dust collection box 671 is fixed to the bottom of the cabinet and located directly below the dust discharge port. The collection box 672 is disposed inside the dust collection box, and an opening for the collection box to pass through is opened on one side of the dust collection box. One end of the handle 673 is fixed to the side wall of the collection box. One end of the rotating shaft 675 is rotatably connected to the side wall of the dust discharge port. The sealing plate 674 is fixed to the end of the rotating shaft and can seal the dust discharge port. The reset component 676 is a torsion spring, which is sleeved on the rotating shaft, and one end of the torsion spring is... One arm is fixed to the rotating shaft, and the other torsion arm is fixed to the side wall of the dust discharge port; one end of the connecting rod 677 is fixed to the slider; one end of the elastic telescopic rod 678 is fixed to the end of the connecting rod; the ball bearing 679 is rotatably connected to the end of the elastic telescopic rod and abuts against the filter plate. When the slider moves above the dust discharge port, the elastic telescopic rod will press down and flip the sealing plate downward. The impurities that have not been discharged from the filter holes will be pushed onto the sealing plate by the cleaning brush and then slide into the collection box. After cleaning, the cleaning brush is reset, and the reset part will drive the sealing plate to reset, thereby sealing the dust discharge port and preventing the dust in the collection box from re-entering the cabinet. When there is a lot of dust in the collection box, the collection box can be taken out of the dust collection box for cleaning by using the handle.

[0040] In other embodiments, sound-absorbing cotton 131 is fixed on the air guide plate 13.

[0041] In other embodiments, the bottom of the cabinet 1 is provided with support feet 14.

[0042] The above description is merely a selection of preferred embodiments of this disclosure and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the invention involved in the embodiments of this disclosure is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the above-described inventive concept. For example, technical solutions formed by substituting the above-described features with (but not limited to) technical features with similar functions disclosed in the embodiments of this disclosure.
