Problems solved by technology

But no matter which filter working mode is used for air purification, the same problem is encountered, that is, the filter layer that plays a decisive role in purifying the air will soon be blocked by pollutants, and within a short period of time (generally not More than 40 days), its filtering performance will be invalid. It should be pointed

Embodiment 1

[0031] Embodiment 1: The present invention includes a vortex 1, an electrostatic precipitator 2, a pipeline 3, an axial flow fan 4, an air rectifier 5, at least one high-efficiency filter layer 6, and an odor filter layer 7. The vortex 1 As for a port inside the pipeline 3, the vortex 1 shaft is fixed on the inner wall of the pipeline 3, and the electrostatic dust collector 2 is attached to the inner wall of the pipeline 3, and the electrostatic dust collector 2 is near the end of the vortex 1, and the pipeline 3 A fixed axial-flow induced draft fan 4 is arranged inside the other port, and the two ports of the pipeline 3 form a 90° angle. The other port of the pipeline 3 is embedded in the wall 8 and connected to the surface of the air rectifier 5, the high-efficiency filter layer 6, and the filter layer 7. , the outdoor air forms a suction negative pressure under the action of the axial flow induced draft fan 4, and when the air flow passes through the vortex 1, a rotating flo...

Abstract

The invention relates to the technical field of filter manufacturing, and especially relates to a household indoor air filter. A technical scheme to be solved is providing the household indoor air purifying filter against problems existing in the prior art. Airflow passing through a vortice has an eddy flow under the action of a negative pressure generated by outdoor air due to an axial induced draft fan, large dust particles in the airflow are thrown into the wall of a pipeline under the action of the centrifugal force of the eddy flow and are trapped by a static dust trapping device arranged on the wall of the pipeline, and the airflow further passes through an air rectifier, an efficient filter layer and a peculiar smell filter layer, so air is effectively filtered and purified. The filter comprises the vortice, the static dust trapping device, the pipeline, the axial induced draft fan, the air rectifier, at least one efficient filter layer and the like. The filter can be applied to the household indoor air filtration field.

Description

technical field [0001] The invention relates to the technical field of filter manufacture, in particular to a household indoor air filter. Background technique [0002] At present, existing domestic air purifiers in the domestic indoor air purification filter market in the prior art work on the principle of pressurizing the air flow under the action of power machinery, forcing the air flow to pass through the filter (core), and retaining The impurities in the air are removed to obtain a new stream of purified air. The working modes are: 1. Internal circulation type (that is, the indoor air is sucked in from one end of the filter and sent out from the other end, and continuously circulates to achieve the effect of purifying the indoor air). The disadvantage of this method is that the air does not exchange with the outdoor air. Although it is clean, the oxygen content in the air only decreases, not increases, which is not good for human health; 2. Another working method is th...
