However, the conventional air filtering and cleaning device has the following disadvantages: 1. The charged wire is often easy to clean or replace the electrostatic filter and the plate-shaped photocatalyst filter, which causes deformation, bending or fracture to produce a tip and the charged conductor. The gate-shaped structure is prone to carbon deposits, causing the deformed tip to cause sparks due to tip discharge or arcing after rupture, igniting dust on charged conductors, and affecting safety. 2 · The live wire is often pulled up and down tightly during replacement or installation, which is easy to deform due to elastic fatigue and cause uneven discharge, which shortens the service life. 3 · The conventional photocatalyst is applied on a honeycomb or plate-shaped filter, and has a small area of contact with the air. Light can only reach the inner wall of one side of the honeycomb hole.

1230630 V. Description of the invention (3) The backlight cannot be illuminated, and part of the light passes through the honeycomb photocatalyst net, and there is a dead angle, so the light source cannot be fully utilized; and the light source comes from a cold cathode tube or a fluorescent tube, which consumes energy and Short life, does not meet environmental or economic effects. 4 · The light emitting direction of the light source lamp is to radiate outward from its periphery, and the honeycomb photocatalyst filter and the plate photocatalyst filter are placed on one side of the light source lamp, so that the light source lamp ’s light is used. not tall. 5 · The light source lamp emits ultraviolet light along the radiation direction of its periphery. However, the photocatalyst device is only provided on one side of the light source lamp, so the light source is wasted and the life is shortened. The lack of this structure reduces filtering and air. Quality and efficiency. 6 · The device has only one control mode, which is to act on the photocatalyst for sterilization and deodorization simultaneously. It can not select the operation mode according to the soot content in the air. Therefore, when the soot content in the air is still high, the belt is released. Negatively charged ions make the smoke and dust have a negative charge at the same time, so they are more easily adsorbed on the walls, sofas, bed sheets and various furniture, and even on the human body, so the furniture is more dirty and difficult to clean, and the human body is harmed. The long-term harm will be self-evident. 7 · In terms of the circuit structure of the air transition cleaning device, the local voltage ground wire and the low voltage ground wire are not separated, so that high voltage will lead to low voltage, which will cause electric shock. Therefore, it can be seen from the above that the conventional air filtering and cleaning device has obvious inconveniences and defects in actual use, and can be improved.
