Description

Technical Field

[0001] The utility model relates to the technical field of photocatalytic purifiers, in particular to a box-type photocatalytic purifier. Background Art

[0002] With the rapid development of construction, pollutants will be generated after the interior decoration of the house, and the pollutants generated will cause harm to human health. Therefore, it is necessary to use a photocatalytic purifier to process the harmful gases in the room and decompose them into harmless gases through catalysis;

[0003] For example, a photocatalytic air purifier with the publication number "CN218544766U" solves the problem that the photocatalytic air purifier has high energy consumption when using light for a long time and cannot be used at night when using sunlight catalysis by setting a transparent outer shell and a fixed plate. When the transparent outer shell is lit, the fixed plate is aimed at the sun-facing side. When the external sunlight weakens, the photosensitive switch energizes the light-emitting lamp to make the light-emitting lamp emit light. When the lighting conditions are good, the utility model can use natural light to illuminate the catalyst on the photocatalyst carrier ball to activate the work. When the lighting conditions are poor, the light-emitting lamp can be used to assist the work. It is suitable for a variety of lighting conditions and can be adjusted automatically. The utility model is more practical. By setting a transparent outer cover, a connecting tube and a connecting hose, the problem of limited purification range of the photocatalytic air purifier is solved. The connecting hose is pulled to place the connecting hose at a corresponding position indoors, and then the side of the connecting ring away from the transparent outer bright side is aligned with a corresponding smooth plane (such as a floor, a smooth ground, etc.), so that the position of the connecting hose is determined. The fan is started to continuously guide the air in the connecting hose into the connecting tube, and continuously transport it to the transparent shell through the connecting hole on the transparent shell. By using the connecting hose, the working range of the utility model can be greatly increased, and it is no longer limited to the air near the transparent shell, and the purification range is greatly increased.

[0004] When the above technical solution is in use, the outside air is sucked into the transparent casing by a fan, and the dust in the air is filtered by a transparent screen. However, after long-term use, the filter holes of the transparent screen will be clogged with dust, which will affect the subsequent filtering effect. The staff needs to take it out regularly for cleaning, which increases the workload of the staff.

[0005] Therefore, we proposed that the box-type photocatalytic purifier can solve the above problems well. Utility Model Content
