Technical Field

[0001] The utility model provides a ventilation auxiliary device for removing odors during decoration, belonging to the technical field of decoration odor removal devices. Background Art

[0002] Interior decoration encompasses room design, renovation, furniture arrangement, and various minor decorative touches. It focuses on the interior of a building, encompassing both the design and construction phase and ongoing renovations after moving in. Renovated homes are subject to significant air pollution, with volatile organic compounds (VOCs) releasing over a long period of time. Without proper air treatment, these can be harmful to residents. Currently, air purifiers and air circulation fans are commonly used to remove odors from interior decoration.

[0003] Existing air purification devices can basically meet the needs of use and can remove indoor decoration odors through purification filters. However, the deodorized air can only flow in a certain direction when discharged, and cannot assist ventilation, making it difficult to evenly remove odors from the air in all locations of the house. Existing air circulation fans can promote indoor air flow over a large area and accelerate air convection circulation, thereby achieving the effect of replacing indoor and outdoor air in the whole house, but they cannot remove odors from the air. When the air flows throughout the house, harmful odors such as formaldehyde will also flow, which is not conducive to removing decoration odors. Based on this, the utility model provides a ventilation auxiliary device for removing odors from decoration. Utility Model Content

[0004] The technical problem solved by the utility model is that it is difficult to remove the odor of indoor decoration and realize auxiliary ventilation at the same time, which makes it difficult to evenly remove the odor of the air in various positions of the whole house.

An air distribution outlet is provided above the cold catalyst filter net on all sides and the top wall of the upper side of the filter box, and a support plate is provided on the side wall of the mouth end of the air distribution outlet, and the side wall of the support plate is rotatably connected to a guide cone placed on the inner side of the air distribution outlet.

[0006] Furthermore, a rotating rod is provided on the top of the guide cone, a bearing rotatably connected to the rotating rod is provided on the side wall of the support plate, and a guide protrusion is provided on the guide cone.

[0007] Furthermore, handles are symmetrically provided on one side wall of the filter box, and universal wheels are symmetrically provided on both sides of the bottom of the filter box.

[0008] Furthermore, both side walls of the filter cotton net, the activated carbon filter net, and the cold catalyst filter net are provided with limiting rails that match the inner side walls of the filter box.

[0009] Furthermore, one side wall of the filter cotton net, the activated carbon filter net, and the cold catalyst filter net is provided with a baffle placed outside the filter box, and the side wall of the baffle is provided with a handle.

[0010] Furthermore, the exhaust fan and the exhaust hood are connected through an exhaust pipe, and the top of the exhaust fan is provided with an air outlet placed below the filter cotton net.

[0022] According to the attached Figure 2 、 3 As shown: a filter cotton net 2, an activated carbon filter net 3, and a cold catalyst filter net 4 are inserted into the inner wall of the filter box 1 in sequence from top to bottom. An exhaust fan 5 is provided at the bottom of the filter box 1, and an exhaust hood 6 connected to the exhaust fan 5 is provided on the outer wall of the filter box 1. The exhaust fan 5 and the exhaust hood 6 are connected by an exhaust pipe 17. An air outlet 18 is provided on the top of the exhaust fan 5 and is placed below the filter cotton net 2. An air outlet 7 is provided on the top wall and the upper wall of the filter box 1. By starting the exhaust fan 5, the indoor air of the completed decoration passes through the exhaust hood 6, the exhaust pipe 17, and the exhaust pipe 17. The fan 5 blows air from the air outlet 18 into the filter box 1, filters and removes impurities in the air through the filter cotton mesh 2 and adsorbs harmful gases and odors in the air, and further removes volatile organic compounds formaldehyde, toluene, hydrogen sulfide, chlorobenzene and pollutants in the air through the activated carbon filter 3, and decomposes harmful gases such as formaldehyde, benzene, xylene, etc. again through the cold catalyst filter 4, converting them into harmless carbon dioxide and water, thereby purifying the air and effectively removing indoor decoration odors. The odor-free air is discharged from each air outlet 7 to all directions in the room.

[0023] According to the attached Figure 3 、 5As shown: a support plate 8 is provided on the side wall of the outlet end of the air distribution outlet 7, and the side wall of the support plate 8 is rotatably connected to a guide cone 9 placed on the inner side of the air distribution outlet 7.
