Filter

Abstract

The invention discloses a filter. The filter comprises a frame body and at least one filter screen assembly, wherein the filter screen assembly comprises a filter screen and a guide mechanism; the guide mechanism comprises a sliding block and a sliding groove; the filter screen assembly comprises a first filter screen assembly and a second filter screen assembly which are oppositely arranged; thefirst filter screen assembly comprises a first sliding block and a first filter screen; the second filter screen assembly comprises a second sliding block and a second filter screen; the first slidingblock and the second sliding block are in clamped and fixed connection; the first filter screen and the second filter screen are fixed through magnetic attraction; sliding blocks are connected with adriving motor; the driving motor and a controller are in electric connection; and the controller and a sensor are in electric connection. When the concentration of ozone in air flowing through the filter is high, filter screens are spliced together for forming of a filtering layer; when the concentration of the ozone in the air flowing through the filter is low, and the air is not needed to be filtered, a plurality of the filter screens are split for folding of the filtering layer; thus, energy consumption of the filter is reduced; meanwhile, the service life of the filter is prolonged.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to a high-efficiency filter for gas filtration. Background technique [0002] Some existing machines generate or use excess ozone during use. If it is directly discharged into the air without treatment, it will cause certain harm to the health of nearby humans. Therefore, it is necessary to add a high-efficiency filter to degrade this part of ozone. treatment so that the concentration of ozone entering the air can reach the standard. Generally speaking, the power consumption of the filter unit is proportional to the pressure loss of the gas passing through the unit. The higher the internal pressure loss, the greater the power consumption of the unit. When the concentration of ozone is low and meets the emission standard, the gas does not need to It can be discharged through the filter, and the current filter works normally no matter whether the ozone concentration is high ...
