The central control module 6 is internally provided with the infrared remote control and the WIFI at the same time, automatic and manual mode switching can be realized, the purification device is started and closed through the infrared remote control, remote regulation and control of the intelligent mobile terminal are realized through the WIFI, and finally the connection, remote monitoring and self-defined purification functions of a plurality of devices in the same application environment can be realized.
The high-voltage power supply module 7 is respectively connected with the ionization negative high-voltage contact 42 on the electrostatic dust collection module 4 and the micro electrostatic plate positive high-voltage contact 31 on the micro electrostatic purification module 3, and the high-voltage power supply module 7 is used for providing working electric energy for the whole device. In addition, the ionization grounding contact 41 on the electrostatic dust collection module 4 and the micro electrostatic plate grounding contact 32 on the micro electrostatic purification module 3 are respectively connected in a grounding manner, so that the safety coefficient of the equipment is improved.
As shown in fig. 4, the discharge electrode of the electrostatic dust removal module 4 adopts a sawtooth tip structure 43, the distance c between the tops of two fixedly connected tips is 22-27 mm, and the height b of the sawtooth tip structure 43 is 4.5-5 mm; the grid 1 of the air inlet is used as a negative plate and forms an ionization discharge region with the sawtooth tip structure 43, the space between the connected grids is 7.2-8 mm, and the space between the sawtooth tip structure 43 and the grids is 12.8-13.5 mm.
The sawtooth tip structure 43 is made of SUS430 series stainless steel, the tip angle range a is 14-21 degrees, and the forming mode is stamping and integral forming, so that the sawtooth tip structure 43 is generated by top distortion.

And when the angle range of the tip is between 14 and 21 degrees, higher anion amount and lower concentration ozone amount can be realized. This is probably because the SUS430 stainless steel series of ferrite material, with the addition of titanium component, can increase the amount of negative ions generated during the ozone conversion process in the case of high-voltage ionization, interrupt and weaken the process, and suppress the generation of ozone to some extent.
The whole structure of the device is a cuboid, the style of the outer frame structure is diversified, and the size can be adjusted according to the actual site requirement so as to adapt to air conditioner product structures of different manufacturers or air conditioner indoor unit air port structures of different models and specifications of the same manufacturer, thereby achieving the purpose of coordinating the butt joint structure and the appearance; the installation is dismantled simple and conveniently swiftly, and the washing is changed easily, saves space and use cost.
