Photocatalytic air purification device capable of modularly replacing filter element

Abstract

The invention discloses a photocatalytic air purification device capable of modularly replacing a filter element, which relates to the technical field of air purification devices. The photocatalytic air purification device comprises a purification machine body, a containing groove is formed in one side of the purification machine body, a filter element inserting groove is formed in the inner wall of one side of the containing groove, a splicing frame is arranged in the filter element inserting groove, a fixing frame is arranged in the splicing frame, a photocatalytic filter screen is fixedly connected to the inner wall of the fixing frame, fixing baffles are fixedly connected to the four inner walls of the fixing frame, and the four fixing baffles make contact with the fixing frame locally. When the filter element module is replaced, the clamping rod can be inserted into the clamping groove to drive the two pieces of protective cloth to cover the two sides of the splicing frame respectively, so that the splicing frame is coated, and the situation that when the filter element module is taken out, dirt, harmful substances and the like accumulated on the photocatalytic filter screen fall off or drift away to pollute the purifier and the surrounding environment, and the physical and psychological health of the user is influenced can be prevented.

Description

technical field [0001] The invention relates to the technical field of air purification devices, in particular to a photocatalytic air purification device for modular replacement of filter elements. Background technique [0002] With the improvement of people's living standards, the requirements for the housing environment are getting higher and higher. Most people will choose to use air purifiers to purify the air in the room. Among them, photocatalytic air purifiers are gradually being used as a new type of purification device. It is accepted that the essence of photocatalytic reaction is redox reaction in photoelectric conversion, and nano-semiconductor particles are generally used as photocatalysts. [0003] When the existing photocatalytic air purification device is in use, a lot of dirt and toxic by-products will accumulate on the photocatalytic net on the filter element module, and the existing purification device does not correct the filter element module or the filt...

Problems solved by technology

[0003] When the existing photocatalytic air purification device is in use, a lot of dirt and toxic by-products will accumulate on the photocatalytic net on the filter element module, and the existing purification device does not correct the filter element module or the filter element when replacing the filter element module. The net is wrapped for protection, so that the dirt and toxic substances on the filter will fall or scatter, pollute the surrounding environment, and affect the physical and mental health of personnel. Therefore, in order to solve the above problems, this application proposes a photocatalytic air purification device
