Description

Technical Field

[0001] This utility model relates to the field of air purifier technology, specifically to a multi-directional air outlet air purifier. Background Technology

[0002] An air purifier is a household or commercial appliance that can improve indoor air quality and reduce harmful substances in the air. Its core function is to filter, adsorb, decompose or transform pollutants in the air through physical, chemical or biological means, thereby providing a cleaner and healthier breathing environment.

[0003] In the prior art, such as the air purifier disclosed in Chinese Patent Publication No. CN114466996A, there is a shell, and the shell has a filter chamber and a drive chamber arranged at intervals. The filter chamber is provided with a filter screen, and the drive chamber is provided with a fan. The shell is provided with an air inlet for outside air to enter the filter screen. There is an air inlet structure between the filter chamber and the drive chamber for air filtered by the filter screen to enter the drive chamber. The shell is also provided with an air outlet structure for air in the drive chamber to return to the outside. The air inlet structure includes a first air inlet surface and a second air inlet surface. The first air inlet surface extends axially into the hollow area of ​​the filter screen and is coaxially arranged with the fan. The second air inlet surface extends from the periphery of the first air inlet surface to the port of the filter screen facing the fan. Multiple air inlets are evenly distributed circumferentially on both the first air inlet surface and the second air inlet surface. The existing air purifiers of this type have the following technical problems: they use a single fan for air intake, and after the air enters the purifier from the outside, it is output through a single air duct, which cannot exhaust air from all sides. The applicable purification area is small and cannot meet the needs of high-efficiency purification. Utility Model Content

[0004] The purpose of this invention is to solve the above-mentioned technical problems and provide a multi-directional air purifier.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

From top to bottom, the housing contains an activated carbon filter assembly, a first fan, a filter assembly, a second fan, and a formaldehyde removal assembly. A top plate is fixedly connected to the top of the housing, and a first mesh air outlet is provided on the top plate. A bottom plate is fixedly connected to the bottom of the housing, and a second mesh air outlet is provided on the bottom plate. The first fan delivers air upwards from below, and the second fan delivers air downwards from above. A third mesh hole is provided on the side wall of the housing. External air enters the housing cavity through the filter assembly. One stream of air passes upwards through the activated carbon filter assembly, while another stream passes outwards and to the bottom through the formaldehyde removal assembly.

[0007] Furthermore, a guide plate is fixedly connected to the middle of the base plate. The guide plate is arranged in a cone shape with a higher center, and the second mesh air outlet is located on the outside of the guide plate.

[0008] Furthermore, multiple partitions are fixedly connected to the box body, and a first through hole is opened in the middle of the partition to allow air to flow up and down. The partitions are attached to the upper and lower surfaces of the activated carbon filter assembly, the filter screen assembly, and the formaldehyde removal assembly.

[0009] Furthermore, one side of the box is designed as an open structure, and a door panel is hinged to the open side of the box; the activated carbon filter assembly, the filter screen assembly, and the formaldehyde removal assembly are laterally slidably inserted into the partition.

[0010] Furthermore, the activated carbon filter assembly includes a first frame and an activated carbon block fixed within the first frame, wherein adsorption pores are formed inside the activated carbon block.

[0011] Furthermore, the filter assembly includes a second frame and a filter screen fixed in the second frame. The filter screen is configured as a hollow cylindrical structure and has mesh holes for filtering.

[0012] Furthermore, the formaldehyde removal component includes a third frame and a formaldehyde removal filter fixed in the third frame, wherein the formaldehyde removal filter is made of honeycomb material impregnated with a formaldehyde removal catalyst.

[0013] The present invention provides a multi-directional air purifier with the following beneficial effects: by setting a first fan and a second fan, external air is drawn into the housing from the outside of the filter assembly. The first fan then sends part of the airflow upward through the activated carbon filter assembly and outputs it from the top outward. The second fan sends part of the airflow downward through the formaldehyde removal assembly and outputs it to the outside and bottom, thereby achieving multiple air outlets and improving the air purification effect.

[0021] like Figures 1-2As shown, a multi-directional air purifier includes a housing 1. Inside the housing 1, from top to bottom, are arranged an activated carbon filter assembly 2, a first fan 3, a filter assembly 4, a second fan 5, and a formaldehyde removal assembly 6. A top plate 11 is fixedly connected to the top of the housing 1, and a first mesh air outlet 12 is provided on the top plate 11. A bottom plate 13 is fixedly connected to the bottom of the housing 1, and a second mesh air outlet 14 is provided on the bottom plate 13. The first fan 3 delivers air upwards from below, and the second fan 5 delivers air downwards from above. A third mesh hole 15 is provided on the side wall of the housing 1. External air enters the inner cavity of the housing 1 through the filter assembly 4. One stream of air passes upwards through the activated carbon filter assembly 2 from above, and the other stream passes outwards and to the bottom through the formaldehyde removal assembly 6 from below.

[0022] By adopting the above technical solution, by setting the first fan 3 and the second fan 5, external air is drawn into the housing 1 from the outside of the filter assembly 4. The first fan 3 then sends part of the airflow upward through the activated carbon filter assembly 2 and outputs it from the top outward.

[0023] Specifically, a guide plate 7 is fixedly connected to the middle of the base plate 13. The guide plate 7 is arranged in a cone shape with a higher center, and the second mesh air outlet 14 is located on the outside of the guide plate 7. The air delivered downward by the formaldehyde removal component 6 is guided by the guide plate 7 and output outward at an angle to the base plate 13, thereby avoiding direct airflow onto the ground and blowing up dust.

[0024] Specifically, multiple partitions 8 are fixedly connected to the housing 1. The partitions 8 have a first through hole 81 in the middle to allow air to flow up and down. The partitions 8 are attached to the upper and lower surfaces of the activated carbon filter assembly 2, the filter screen assembly 4, and the formaldehyde removal assembly 6.

[0025] Specifically, one side of the housing 1 is designed as an open structure, and a door panel 16 is hinged to the open side of the housing 1; the activated carbon filter assembly 2, the filter screen assembly 4, and the formaldehyde removal assembly 6 are laterally slidably inserted into the partition 8. By designing one side of the housing 1 as an open structure, the activated carbon filter assembly 2, the filter screen assembly 4, and the formaldehyde removal assembly 6 can be pulled out for easy replacement of the filter screen, activated carbon block 22, or formaldehyde removal honeycomb block.

[0026] Specifically, the activated carbon filter assembly 2 includes a first frame 21 and an activated carbon block 22 fixed within the first frame 21, wherein the activated carbon block 22 has adsorption pores formed inside.

[0027] Specifically, the filter assembly 4 includes a second frame 41 and a filter screen 42 fixed in the second frame 41. The filter screen 42 is configured as a hollow cylindrical structure and has mesh holes for filtering.

[0028] Specifically, the formaldehyde removal component 6 includes a third frame 61 and a formaldehyde removal filter 62 fixed in the third frame 61. The formaldehyde removal filter 62 is made of honeycomb material impregnated with a formaldehyde removal catalyst. By impregnating the honeycomb material with the formaldehyde removal catalyst, the passing air is catalytically decomposed.

[0029] The parts not covered in this technical solution can be implemented using existing technologies.
