Description

Technical Field

[0001] The utility model relates to the field of fresh air devices, in particular to an air outlet assembly of a fresh air system. Background Art

[0002] The air outlet panel is arranged at the air outlet of the fresh air system, and the air flow is evenly dispersed through the grille of the air outlet panel. To improve the control quality, a filter screen needs to be arranged inside the air outlet panel to purify the air sent into the room.

[0003] The existing air outlet panel is a fixed plate frame structure, and the filter screen is fixed inside the air outlet panel through an internal sandwich or screws. The filter screen needs to be taken out regularly for cleaning. For the fixed air outlet panel, the screws need to be disassembled to remove it, and then the filter screen is taken out. The removal and installation of the filter screen are rather cumbersome. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an air outlet assembly of a fresh air system to solve the problem that the existing air outlet panel needs to disassemble screws to remove and install the filter screen.

[0005] To solve the problems existing in the prior art, the technical solution of the utility model is as follows:

[0006] An air outlet assembly of a fresh air system includes a frame. A wind guiding plate is rotatably arranged inside the frame. A filter plate is inserted into the bottom surface of the wind guiding plate. Inner stoppers and outer edges are respectively arranged at two ends of the frame. The inner stoppers and outer edges respectively abut against the lower part of one end and the upper part of the other end of the wind guiding plate, restricting the wind guiding plate to rotate only in one direction. A retaining post elastically slides through a spring at a position on the side of the frame close to the outer edge. The retaining post abuts against the bottom of the wind guiding plate upward, making both ends of the wind guiding plate closely abut against the inner stoppers and outer edges.

[0007] Preferably, buckle strips are symmetrically and fixedly arranged on both sides of the bottom surface of the wind guiding plate, and both sides of the filter plate are slidably inserted into the buckle strips.

[0008] Preferably, a pulling strip is convexly arranged at one end of the filter plate close to the inner stopper.

[0009] Preferably, U-shaped card slots are symmetrically and fixedly arranged on both sides of the frame, and elastic pieces are fixed inside the card slots. Axial columns are symmetrically and fixedly arranged on both sides of the wind guiding plate, and the axial columns are inserted into the card slots and are abutted and limited by the elastic pieces.

[0010] Preferably, the elastic piece is in a U shape, and the top opening of the elastic piece is in an elastic closed shape.

[0011] Preferably, the wind guiding plate includes an inner frame, and a plurality of grille plates are evenly arranged inside the inner frame.

[0012] Preferably, both ends of the inner frame are arc-shaped. When the inner frame is flush with the frame, both ends of the inner frame abut against the inner side of the frame.

[0013] Compared with the related art, the utility model has the following beneficial effects:

[0014] In the utility model, the inner frame is rotatably installed on the plate frame, and the one-way rotation of the inner frame is limited by the inner stop block and the outer stop edge. Cooperating with the stop post elastically abutting against the inner frame, the inner frame and the plate frame are kept parallel. By pressing the inner frame to turn over, the filter plate can be taken out or inserted from the lifted end of the inner frame, which is convenient for regular cleaning and maintenance of the filter plate.

[0022] In order to make the purpose, technical solutions and advantages of the utility model clearer, the following further describes the utility model in detail with reference to the drawings and embodiments.

[0023] As Figure 1-6As shown, the air outlet component of the fresh air system includes a plate frame 1. The four sides of the plate frame 1 have planar extension parts, enabling the plate frame 1 to be fixedly installed flat. The air deflector includes an inner frame 2. A number of grid plates 3 are evenly arranged on the inner side of the inner frame 2. The inner frame 2 is placed inside the plate frame 1. The two sides of the inner frame 2 are rotatably connected to the plate frame 1. On both sides of the bottom surface of the inner frame 2, buckle strips 71 are symmetrically fixed. The two sides of the filter plate 7 are slidably inserted into the buckle strips 71, making the filter plate 7 flat against the inner side of the inner frame 2. At both ends of the inner frame 2, inner stoppers 11 and outer edges 12 are respectively fixed. The inner stoppers 11 and the outer edges 12 respectively abut against the lower part of one end and the upper part of the other end of the air deflector, restricting the air deflector to rotate only in one direction. On both sides of the plate frame 1 near the outer edges 12, chutes are opened. In the chutes, a retaining post 5 is elastically slidably installed through a spring. The retaining post 5 abuts upward against the bottom of the inner frame 2;

[0024] By the retaining post 5 abutting upward against the inner frame 2 and cooperating with the inner stoppers 11 and the outer edges 12 abutting against both ends of the inner frame 2, the inner frame 2 is kept parallel to the plate frame 1. Air is filtered by the filter plate 7 and directionally led out by the grid plates 3. When cleaning the filter plate 7, press one side of the inner frame 2 close to the outer edge 12, so that the inner frame 2 overcomes the elastic force and presses down the retaining post 5. The inner frame 2 flips, causing one end of the inner frame 2 close to the inner stopper 11 to protrude out of the plate frame 1. The filter plate 7 is drawn out from this end for cleaning. After the cleaned filter plate 7 is reinserted into the buckle strips 71, release the inner frame 2. The inner frame 2 is automatically reset by the elastic push of the retaining post 5.

[0025] The rotational connection between the inner frame 2 and the plate frame 1 is as follows:

[0026] As Figure 3-5 shown, on both sides of the plate frame 1, U-shaped card slots 4 are symmetrically fixed. Inside the card slots 4, elastic pieces 41 are fixed. The elastic pieces 41 are also U-shaped. The top openings of the elastic pieces 41 are elastically closed. On both sides of the inner frame 2, shaft columns 6 are symmetrically fixed. The shaft columns 6 are clamped into the elastic pieces 41 from the closed positions of the elastic pieces 41. The shaft columns 6 are elastically clamped by the elastic pieces 41, enabling the inner frame 2 to rotate relative to the plate frame 1.

[0027] As Figure 6 shown, at one end of the filter plate 7 close to the inner stopper 11, a pull bar 72 is convexly provided, facilitating the extraction of the filter plate 7 from the pull bar 72.

[0028] Both ends of the inner frame 2 are arc-shaped. When the inner frame 2 is flush with the plate frame 1, both ends of the inner frame 2 abut against the inner side of the plate frame 1, narrowing the gap between the inner frame 2 and the plate frame 1, and there is a certain locking effect when the inner frame 2 abuts against the plate frame 1.

[0029] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
