Embodiment 1

[0037] The mechanism of electric purification is that a large number of charged ions are generated by ionization first, and the particles are charged after the charged ions collide with the particles. Under the action of the electric field, the charged particles move to the collector 2. Generally speaking, for charged particles, as shown in Table 1, the driving speed generated by the electric field force is relatively small. Relatively speaking, the electrode distance is too wide, and it takes a long enough time to reach one side of the electrode. Therefore, either make the electrode long enough so that the charged particles have enough time to move to the collector 2 under the action of the electric field, which makes the electrode structure very large, and the volume of the electric purification product is too large, which also leads to insufficient purification efficiency; or the designed collection The poles 2 are dense enough to shorten the moving distance of the charged p...

Abstract

The invention relates to the technical field of air purification, in particular to an electric purification device and an air purifier. The electric purification device comprises an ionization electrode used for ionizing airflow to be purified, and a collector. The collector is movably arranged to construct a dynamic interception surface, and the moving direction of the collector intersects with the airflow direction; and the ionization electrode is suitable for receiving a first preset voltage, the collector is suitable for receiving a second preset voltage, and the first preset voltage and the second preset voltage form a voltage difference. The ionization pole enables particles in the airflow to carry charges to become charged particles, the charged particles move towards the collector at the driving speed under the action of an electric field, the collector is movably arranged, the moving direction of the collector intersects with the airflow direction, the collector forms the dynamic interception surface, and the charged particles can be intercepted by making contact with the interception surface. The time for the charged particles to move to the collector can be shortened, so that the length of the collector does not need to be increased, the size of the electric purification device can be reduced, and wind resistance cannot be increased.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to an electric purification device and an air purifier. Background technique [0002] At present, there are two purification technologies on the market, one is filtration and the other is electric purification. The advantage of the filter type is that the interception efficiency is high, but the wind resistance is large and the energy efficiency is low. The mechanism of electric purification is that first ionization produces a large number of charged ions, and after the charged ions collide with the particles, the particles are charged. Under the action of the electric field, the charged particles move to the collector. Generally speaking, for charged particles, the driving speed generated by the electric field force is relatively small, relatively speaking, the electrode distance is too wide, and it takes a long enough time to reach one side of the electrode. Therefore, ...
