In the bipolar ion generator in the air purifier, the emission polar plate and the grounding polar plate are connected with current to form an electric field with precise size, and the electrons emitted by the emission polar plate are led out of the medium blocking plate on the grounding side of the electric field by adopting alternating current to generate different-sign gas ions. Due to the compact characteristic of medium discharge, part of electrons flow into the grounding polar plate after meeting the grounding polar plate to form current, and the other part of electrons escape from the surface of the medium and meet indoor air molecules, when the escaping electrons reach a certain speed, oxygen molecules can be excited to be in an ionic state, ionized gas enables the particles to be electrified, the particles in the air can be easily reduced when the charged particles meet the grounding electrode or a reversed polarity object, floating dust in the air is converted into dust fall, the floating particles are reduced, simultaneously the generated unbalanced oxygen ions have the physical impact effect of high kinetic energy, the decomposition of harmful volatile gas molecules is facilitated under the dual effects of physical action and chemical action, the sterilization effect on pathogenic microorganisms can be realized, and the purposes of air purification and sterilization are achieved.

According to the elevator and the air purifier in the elevator car, the airflow driving piece and the bipolar ion generator are arranged in the first shell, when the air purifier works, positive and negative purification ions generated by the ion sheet can be carried and diffused to the whole space in the elevator car by airflow under the driving action of the airflow driving piece, so that the comprehensive and continuous purification effect of the whole car space is realized, planktonic bacteria in the air entering and exiting the elevator car can be effectively killed, inhalable particles in the air are reduced, TVOC in the air is decomposed, peculiar smell is eliminated, the air quality in the elevator car is effectively improved, and a user can take the elevator more comfortably and healthily. In addition, the bipolar ion generator in the air purifier facilitates the installation, maintenance and replacement of the ion sheet by connecting the plug with the ion sheet in a pluggable manner, and when the ion sheet breaks down, only the plug needs to be pulled down and the ion sheet needs to be replaced without replacing a power converter, other circuit structures or electronic components in the air purifier.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
