Abstract

An air purification device, comprising a motor (30) and a fixed wheel (20) driven by a shaft of the motor (30). The fixed wheel (20) is divided into an inner ring (21) and an outer ring (22). Between the inner ring (21) and the outer ring (22) is provided a folding filter paper (50). At the periphery of the fixed wheel (20) is provided an air channel casing (40). The air channel casing (40) is fixed to the wheel (20) to form an inflow-outflow air channel. The fixed wheel (20) fixes the filter paper (50), and the filter paper (50) rotates as a wheel blade and utilizes centrifugal speed to push air into an air outflow channel. That is, the filter paper (50) serves as a wheel blade, and at the same time filters air, thereby saving the space that would be occupied by a filter paper, reducing the volume of the air purification device. The air channel casing (40) design improves output air volume.

Preferably, the outer folding point of the filter paper is fixed in the fixing groove by a fixing glue.

Preferably, the fixing column has a triangular cross section, wherein an angle of one corner is the same as or similar to an inner angle of the inner folding point.

Preferably, an air inlet window is disposed at a central position above the air duct shell, and an air outlet is disposed on a side of the air duct shell, and a closed bottom shell is disposed below the air duct shell.

Preferably, a panel cover is arranged around the air duct shell.

Advantageous Effects: According to the above technical solution, the present invention uses the filter paper as a blade in the prior art by using a fixed wheel to fix the filter paper, and then presses the air through the centrifugal speed during the rotation process. Entering the air duct, which not only functions as a vane but also filters the air, saves the space required for the additional filter paper, greatly reduces the volume of the air purifying device, and at the same time, the design of the air duct shell The amount of air output will also increase significantly.

detailed description

The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to FIGS. 3-7, the present embodiment provides an air purifying apparatus including a motor 30, a fixed wheel 20 driven by a shaft core of the motor 30, and the fixed wheel 20 is divided into an inner ring 21 and an outer ring 22, A folding filter paper 50 is disposed between the inner ring 21 and the outer ring 22. The outer side of the fixed wheel 20 is provided with a duct shell 40. The duct shell 40 and the fixed wheel 20 constitute an air inlet and outlet duct. An air inlet window is disposed at a central position above the air duct shell 40. An air outlet is disposed on a side of the air duct shell 40, and a closed bottom shell 60 is disposed below the air duct shell 40. A panel cover 10 is disposed on the periphery of the air duct shell 40. An air inlet 11 is disposed at an upper position of the panel cover 10, and an air outlet window 12 is disposed around the panel cover 10. The inner side of the outer ring 22 of the fixed wheel 20 is provided with a plurality of columnar fixing grooves 24 whose opening directions are offset in the clockwise direction, and a gap is formed between the fixing grooves 24, and the outer side of the inner ring 21 is provided with the The fixing post 23 corresponding to the gap has a triangular cross section, wherein the angle of one corner is the same as or close to the inner corner angle of the inner folding point 51 of the filter paper 50. The outer folding point 52 of the filter paper 50 is inserted into the fixing groove 24, and the inner folding point 51 of the filter paper 50 is sleeved on the fixing post 23.
