Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of photocatalyst air purification, especially to a photocatalyst-based air purification filter element. BACKGROUND

[0002] In contemporary architecture, a large number of various decorative materials, furniture and the like are used, and these materials continuously release volatile organic compounds represented by formaldehyde and various nitrogen oxides and other harmful gases. These pollutants exist in indoor air for a long time, causing serious threats to human health, such as causing respiratory diseases, allergic reactions, and even possibly causing cancer. At the same time, the indoor environment is relatively closed, and air circulation is poor, making it easier for pollutants to accumulate, so effective purification technology is needed to improve indoor air quality.

[0003] Traditional air purification technology mainly relies on the adsorption of activated carbon to remove gaseous pollutants. However, the adsorption capacity of activated carbon is limited, and as the use time increases, its micro-pores are gradually filled, and the adsorption efficiency gradually decreases. Even after the adsorption capacity reaches a certain level, harmful substances will be released in the opposite direction, and the filter element needs to be frequently replaced, which is relatively high in use cost. Photocatalyst is a general term for a kind of photo-semiconductor material with photocatalytic function represented by nanoscale titanium dioxide. It is coated on the surface of the substrate and can produce strong catalytic degradation function under the action of ultraviolet light and visible light. Photocatalyst can effectively degrade toxic and harmful gases in the air, effectively kill various bacteria, and decompose and harmless the toxins released by bacteria or fungi. It also has the functions of removing formaldehyde, deodorizing, anti-pollution, purifying air, etc. Compared with traditional purification technology, photocatalyst technology has the advantages of no secondary pollution, strong sustainability, etc., and only provides a reaction site, and itself does not participate in chemical reactions. In theory, it can be used for a long time, but during actual use, the air purifier filter element in the room cannot effectively contact the light source, thereby reducing the inactivation rate of the bacterial population by the photocatalyst and losing the ability to decompose pollutants. At the same time, formaldehyde may only be oxidized to formic acid under weak light instead of carbon dioxide, making formic acid more irritating, and thus reducing the overall use effect. Therefore, the present application provides a photocatalyst-based air purification filter element to meet the needs. SUMMARY

[0027] The technical scheme of the present application is described below in combination with the embodiments shown in the drawings: Figures 1-4

[0028] The filter plate base 1 is provided with a receiving cavity 2 on both sides, and the inside of the receiving cavity 2 is slidably connected with a side baffle 4 through an electric push rod 3, and the side baffle 4 seals the receiving cavity 2, and the top of the side baffle 4 is fixedly connected with an ultraviolet lamp assembly 5 through a mounting cavity, and the side wall of the side baffle 4 is provided with a limiting assembly for limiting the position of the side baffle 4, and the periphery of the filter plate base 1 is sleeved with a first filter plate mounting assembly 8, a second filter plate 9 and a third filter plate 10, and the second filter plate 9 and the third filter plate 10 are provided with mounting assemblies, and the mounting assemblies are used to connect the first filter plate mounting assembly 8, the second filter plate 9 and the connecting plate 19, and the top of the filter plate base 1 is provided with a filter plate top plate 11, and the shape of the filter plate base 1 and the filter plate top plate 11 is a longitudinal section of a H-shaped structure.

The first filter plate mounting assembly 8, the second filter plate 9 and the third filter plate 10 are sleeved on the side of the filter plate base 1, so that the filter plate top plate 11 is aligned with the filter plate base 1, and then the filter plate top plate 11 is pressed, so that the filter plate top plate 11 is clamped on the top of the filter plate base 1. At this time, the clamping structure of the filter plate top plate 11 can effectively limit the longitudinal height position of the first filter plate mounting assembly 8, the second filter plate 9 and the third filter plate 10, so that they remain stable during use. The air can be directly filtered and adsorbed by the first filter plate mounting assembly 8, the second filter plate 9 and the third filter plate 10. During long-term use, the electric push rod 3 can be controlled by an external controller, so that the electric push rod 3 can effectively drive the side baffle 4 to slide, so that the side baffle 4 slides away from the inside of the containing cavity 2. The titanium dioxide in the first filter plate mounting assembly 8, the second filter plate 9 and the third filter plate 10 can be directly acted on by the ultraviolet lamp assembly 5 inside the ultraviolet lamp assembly 5, so as to react with water and oxygen in the air to generate hydroxyl radicals and superoxide radicals, decompose organic matter, inactivate microorganisms, and improve the effect during use.

[0036] The mounting assembly includes a mounting frame 18 fixedly connected to the side walls of the first filter plate mounting assembly 8 and the second filter plate 9, and the top of the mounting frame 18 is clamped with a connecting plate 19, and the other side of the second filter plate 9 and the third filter plate 10 are fixedly connected with the side walls of the connecting plate 19.

[0037] When connecting the first filter plate mounting assembly 8 and the second filter plate 9, the connecting plate 19 connected to the second filter plate 9 can be directly aligned with the mounting frame 18 on the side wall of the first filter plate mounting assembly 8, so that the connecting plate 19 is pressed to move downward under the action of force, and then clamped in the inside of the mounting frame 18, at this time, the clamping structure of the mounting frame 18 and the connecting plate 19 can effectively limit the position of the first filter plate mounting assembly 8 and the second filter plate 9, and when connecting the second filter plate 9 and the third filter plate 10, the connecting plate 19 on the third filter plate 10 is aligned and clamped with the mounting frame 18 on the second filter plate 9, so that the first filter plate mounting assembly 8, the second filter plate 9 and the third filter plate 10 are synchronously clamped and fixed, thereby ensuring the overall stability of use.

[0040] A plurality of elastic bands 22 are arranged on the filter plate base 1, and the elastic bands 22 are clamped on the filter plate top plate 11, after the installation is completed, the elastic bands 22 can be directly pulled to make the elastic bands 22 be forced to deform and elongate, so as to be effectively clamped in the inside of the filter plate top plate 11, at this time, the elastic bands 22 can effectively limit the position between the filter plate base 1 and the filter plate top plate 11, and guarantee the stability of the filter plate top plate 11 during use.
