The light emitting unit 32 is disposed on a side of the light source plate 31 facing the photocatalyst plate 2.
The direction of the air flow illustrated in fig. 1 is the direction from the photocatalyst plate 2 to the light source assembly 3. Of course, the direction of the air flow may be reversed from the light source assembly 3 to the photocatalyst plate 2, so long as the air flow is ensured to flow through the photocatalyst plate 2 and the light emitting unit can irradiate the photocatalyst plate 2.
The deodorizing device provided by the embodiment of the application comprises a frame 1, a photocatalyst plate 2 and a light source assembly 3. The frame 1 is a mounting carrier for the photocatalyst plate 2 and the light source component 3, and plays a role in fixing the photocatalyst plate 2 and the light source component 3. The frame 1 has a hollow structure, i.e., an inner hollow structure, and only has a circle of side circumference, and air flow can flow through the hollow space of the frame 1, so the hollow space of the frame 1 is the air flow channel 11. The photocatalyst plate 2 includes a substrate 21, a photocatalyst layer, and a hemming member. The substrate 21 is a carrier of the photocatalyst layer. The photocatalyst layer is a layered structure formed by a photocatalyst (or photocatalyst), and is attached to the substrate 21. The substrate 21 is in a honeycomb structure, which may be, but is not limited to, aluminum honeycomb. The honeycomb structure has rich honeycomb holes 22 through which the air flow can pass, so that the honeycomb structure has a very large specific surface area, and is beneficial to increasing the adhesion amount of the photocatalyst and the contact area with the air flow, thereby being beneficial to improving the photocatalytic deodorizing effect. The edge covering component can carry out cladding treatment on the outer peripheral wall of the honeycomb substrate 21, so that the outer side wall structure of the photocatalyst plate 2 is relatively regular, and can bear force, thereby facilitating the connection between the photocatalyst plate 2 and the frame 1.

When the airflow flows through the deodorizing device, the peculiar smell pollutants can be degraded into carbon dioxide and water by the photocatalyst, so that deodorizing effect is realized. The odor pollutant is thoroughly degraded into carbon dioxide and water and is not adsorbed and accumulated in the photocatalyst plate 2, so that the photocatalyst plate 2 does not need to be replaced, the consumable problem does not exist, and the odor pollutant is not released to the outside again, so that the secondary pollution problem does not exist.
The photocatalyst may be, but is not limited to, a P25 type photocatalyst. The P25 photocatalyst is a commonly used photocatalytic material, also called titanium dioxide (P25 TiO 2 ). It is composed of nano-level titanium dioxide particles, and has high catalytic activity and light absorption capacity.

(6) Production of H 2 O 2 ：2HOO·→H 2 O 2 +O 2
(7) Producing hydroxyl radicals: h 2 O 2 +O 2 - →O 2 +OH·+OH -

From expression (8), it is known that active oxygen species such as free hydroxyl groups and peroxy ions generated during the photocatalytic process can degrade pollutants.
In some exemplary embodiments, an organic adhesive layer (not shown) is disposed between the substrate 21 and the photocatalyst layer. The substrate 21 may be an aluminum honeycomb panel. The purpose of the organic adhesive layer is to isolate the photocatalyst layer from the substrate 21 and to provide sites for the photocatalyst to be supported. In the production process, a layer of organic adhesive is loaded on the substrate 21 to form an organic adhesive layer, and then the photocatalyst is sprayed and loaded on the organic adhesive layer to form a photocatalyst layer.
The organic adhesive can be, but is not limited to, acrylic acid ester or ethyl acetate adhesives. The photocatalyst can be dispersed in ultrapure water, sprayed on the organic adhesive layer, and then dried, wherein the drying temperature can be in the range of 80 ℃ to 90 ℃ but not limited to, and the drying time can be about 0.5 h.
In some exemplary embodiments, the light emitting unit 32 may be, but is not limited to, an LED or the like or a mercury lamp.

The plurality of light emitting units 32 may be disposed at intervals on the light source plate 31 to provide uniform ultraviolet irradiation to the photocatalyst plate 2.
In some exemplary embodiments, the central axes of the honeycomb holes 22 are disposed obliquely with respect to the extending direction of the airflow channels 11.
Compared with the arrangement that the central axis of the honeycomb hole 22 is parallel to the extending direction of the air flow channel 11, the inclined arrangement scheme is beneficial to prolonging the length of the honeycomb hole 22, thereby increasing the residence time of the air flow in the honeycomb hole 22, being beneficial to the full reaction of the air flow and the photocatalyst on the wall of the honeycomb hole 22, and being beneficial to improving the deodorizing performance.
Wherein the inclination angle of the central axis of the honeycomb holes 22 with respect to the extending direction of the air flow passage 11 may be in the range of, but not limited to, 30 ° to 45 °, such as 30 °, 35 °, 40 °, 45 °, and the like. This range is advantageous for both prolonging the residence time of the air flow in the honeycomb holes 22 to improve the deodorizing performance and avoiding the influence of excessive wind resistance on the air outlet efficiency of the air treatment device due to the excessive inclination angle.
In some exemplary embodiments, the cross-section of the honeycomb holes 22 is polygonal, as shown in fig. 3, such as triangular, quadrilateral, pentagonal, hexagonal, and the like. The side length of the honeycomb holes 22 can be in the range of, but not limited to, 1.3mm to 1.5mm, which is beneficial to providing rich honeycomb holes 22 to improve the deodorizing performance and to avoid the influence of excessive wind resistance caused by too thin honeycomb holes 22 on the air outlet efficiency of the air treatment equipment.
In some exemplary embodiments, the spacing between the light source plate 31 and the photocatalyst plate 2 may be in the range of, but is not limited to, 10cm to 15cm, such as 10cm, 11cm, 12cm, 13cm, 14cm, 15cm, etc. This is advantageous in ensuring that each light emitting unit 32 can cover the photocatalyst plate 2 with a proper area, and can irradiate the wall of the honeycomb hole 22, and provide proper ultraviolet light energy, i.e. the irradiation intensity and the irradiation area are both taken into consideration, so as to improve the deodorizing performance.
In some exemplary embodiments, the frame 1 is provided with relief grooves 12 at both ends in the first direction, as shown in fig. 4. Both ends of the light source plate 31 in the first direction are embedded in the escape grooves 12 as shown in fig. 1.
On the one hand, the light source plate 31 can be prevented from protruding out of the frame 1, so that the structure of the deodorizing device is smooth, the deodorizing device is convenient to mount on air treatment equipment, and packaging and transportation are also convenient; and the thickness of the deodorizing device is not too large, which is beneficial to the miniaturization of the deodorizing device.
And, the two avoidance grooves 12 can also play a role in positioning and limiting the installation of the light source plate 31, thereby being beneficial to improving the assembly efficiency of the deodorizing device.
In some exemplary embodiments, both ends of the frame 1 in the second direction are spaced apart from both ends of the light source plate 31 in the second direction, as shown in fig. 1. One of the first direction and the second direction is the longitudinal direction of the frame 1, and the other is the width direction of the frame 1.
