The invention attaches the powder releasing negative ions to the filter material, can effectively remove the peculiar smell in the air and reduce the indoor pollution, and the purified clean air can bring the negative ions released by the negative ion powder into the air to form the negative ion environment in the toilet.
The filter element capable of releasing negative ions is characterized in that: the filter element has the characteristics that the air flow entering the filter element is disturbed by the surface fluctuating along the straight line X direction and moves up and down between the two adjacent layers to fully contact with the filter material, so that the purification effect is ensured, and meanwhile, the air flow direction is the same as the surface fluctuating direction, the air resistance of the air flow is small, the air throughput in unit time is large, and the purification efficiency is ensured.
As a preferred technical scheme:
according to the filter element capable of releasing the negative ions, the number of the composite layers is multiple, the composite layers are sequentially stacked and arranged, in order to ensure the purification effect, the distance between two adjacent layers in the same composite layer cannot be infinite, so that the gas flux of the same composite layer is limited, in order to improve the efficiency, the composite layers can be arranged in the same main body frame, and can work simultaneously, so that the purification efficiency is effectively improved; all composite bed entrances are located same side, all composite bed exports are located same side, during the use, need will wait to purify the gas and communicate with the entry of different composite beds simultaneously, when all composite bed entrances are located same side, be convenient for connect, when all composite bed entrances are located different sides, also can use, it is relatively complicated only to connect the process, when all composite bed exports are located same side, be favorable to the gas around the separation purifies, avoid mutual disturbance, all composite bed exports also can be located different sides.
