Abstract
Description
Technical Field
[0001] This utility model relates to the field of photocatalytic air purification technology, specifically to a photocatalytic purification device. Background Technology
[0002] Photocatalytic purification is a device that uses light of a specific wavelength (usually ultraviolet light) to irradiate a photocatalyst, causing the photocatalyst surface to generate active oxygen substances, thereby decomposing harmful substances in the air (such as formaldehyde, benzene, and other volatile organic compounds) and bacteria and viruses. In the field of air purification, photocatalytic technology has received widespread attention due to its high efficiency and environmental friendliness. Slanted honeycomb panels, as an important component in photocatalytic purification devices, are used to guide airflow and ensure that light can be evenly irradiated onto the photocatalyst to improve purification efficiency. Early slanted honeycomb panels used a single-layer structure, which in practical applications was difficult to completely block the light source, causing some light leakage, wasting energy, and potentially causing unnecessary light pollution to the surrounding environment. At the same time, increasing the thickness of the single-layer slanted honeycomb panel to improve air purification efficiency increases the space occupied by the entire device and increases wind resistance, affecting airflow and thus reducing overall purification efficiency. Utility Model Content
[0003] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing a photocatalytic purification device. This device uses a double-layer inclined honeycomb panel, which has the advantages of preventing light leakage, reducing wind resistance, increasing air volume, and thus improving overall purification efficiency.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is: a photocatalytic purification device, comprising:
[0005] The housing has an air outlet and an air inlet at its top and bottom, respectively.
[0006] The light-emitting component is assembled inside the housing;
[0007] The inclined honeycomb panel assembly comprises two sets, respectively mounted on the air outlet and the air inlet. The inclined honeycomb panel assembly includes: a frame; a first inclined honeycomb panel disposed within the frame and closer to the light-emitting element; and a second inclined honeycomb panel disposed on the side of the first inclined honeycomb panel away from the light-emitting element.
[0008] A photocatalytic layer is coated on the inner wall of the inclined honeycomb panel assembly, and the light-emitting element emits a light source to photolyze the photocatalytic layer for air purification.
[0009] The first inclined honeycomb plate has a plurality of channels that are inclined toward the central axis of the frame; the second inclined honeycomb plate has a plurality of channels that are connected to the first inclined honeycomb holes and are inclined in the opposite direction to the first inclined honeycomb holes.
[0010] The present invention further comprises: a first plate and a second plate arranged symmetrically to the first plate.
[0011] The present invention further includes the second inclined honeycomb plate comprising: a third plate disposed on the side of the first plate away from the light-emitting element, and a fourth plate disposed on the side of the second plate away from the light-emitting element and symmetrically disposed with the third plate.
[0012] The present invention is further provided that the thickness of the first inclined honeycomb plate is greater than the thickness of the second inclined honeycomb plate.
[0013] The present invention is further provided that the inclination angle of the first oblique honeycomb hole and the second oblique honeycomb hole is 30°-60°.
[0014] The present invention is further provided that the inclination angle of the first oblique honeycomb hole and the second oblique honeycomb hole is 45°.
[0015] The present invention further includes: a box body, a boss disposed on the inner side of the box body for supporting the inclined honeycomb panel assembly, and clamping plates disposed on the upper and lower sides of the box body and cooperating with the boss to clamp and fix the inclined honeycomb panel assembly.
[0016] The present invention further provides that the outer side of the box body is provided with a groove for the user to lift and place the box body.
[0017] The present invention further includes a support frame for mounting the light-emitting element inside the housing.
[0018] The present invention further provides that the light-emitting element includes at least four or more light sources.
[0019] After adopting the above technical solution, the beneficial effects of this utility model are as follows: In this utility model, air is drawn into the purification device from the air inlet at the bottom of the box. The airflow passes through the inclined honeycomb panel assembly assembled on the air inlet. The air flows from the second inclined honeycomb panel into the first inclined honeycomb panel and guides the airflow toward the photocatalyst layer. The light emitted by the light-emitting element irradiates the photocatalyst layer, activating the photocatalyst and generating free radicals with strong oxidizing properties on its surface. As the airflow continues to move forward, the pollutants in the air come into contact with the photocatalyst layer and are decomposed into harmless substances under the action of photocatalysis. The purified air passes through another set of inclined honeycomb panel assemblies on the air outlet to process the air again, ensuring that the remaining pollutants in the air are further purified. Finally, the air is discharged from the purification device to maintain the ambient air quality and complete the entire purification cycle. In the above purification process, the several first and second inclined honeycomb holes set on the inclined honeycomb panel assembly increase the light-receiving area and ensure that the light can be evenly irradiated onto the photocatalyst layer of the inclined honeycomb holes, thereby improving the purification efficiency. The double-layer inclined honeycomb panel setting of the first and second inclined honeycomb panels can effectively block light and prevent light leakage. Moreover, the inclined honeycomb holes that are connected in the double-layer inclined honeycomb panels and have opposite inclination directions do not increase wind resistance. The low wind resistance increases the airflow volume and increases the residence time of air in the purification device, further improving the overall purification efficiency.

Detailed Implementation
[0030] The present invention will be further described in detail below with reference to the accompanying drawings.
[0031] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive element, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
[0032] This embodiment relates to a photocatalytic purification device, as shown in the following figure. Figures 1-7 It includes: a housing 100, a light-emitting component 200, an inclined honeycomb panel assembly 300, and a photocatalyst layer.
[0033] The housing 100 serves as the outer shell of the entire purification device, providing the necessary space for effective air treatment. Air inlets and outlets at its top and bottom ensure air can flow in and out after treatment. The light-emitting element 200, installed within the housing 100, is the energy source for the photocatalytic reaction. It typically uses ultraviolet LEDs or other light sources emitting wavelengths suitable for activating the photocatalyst layer. When light shines on the photocatalyst layer, it excites the photocatalyst to generate highly oxidizing free radicals, thereby decomposing pollutants in the air. The photocatalyst layer is coated or attached to the inner wall of the inclined honeycomb panel assembly 300. A photocatalyst is a material that generates active oxygen under light, most commonly titanium dioxide (TiO2). When the light-emitting element 200 emits light, and the photocatalyst layer is irradiated with light of a suitable wavelength, it generates highly oxidizing free radicals, which can decompose pollutants adsorbed on its surface to purify the air. Two sets of inclined honeycomb panel assemblies 300 are provided, one set installed at the air outlet and the other at the air inlet. The inclined honeycomb panel assembly 300 includes a frame 310, a first inclined honeycomb panel 320, and a second inclined honeycomb panel 330. The frame 310 provides support and positioning for the inclined honeycomb panels. The first inclined honeycomb panel 320 is disposed within the frame 310 on the side closest to the light-emitting element 200, and has several channels on it inclined with first inclined honeycomb holes 321 oriented towards the central axis 311 of the frame 310. The first inclined honeycomb holes 321 help guide the airflow direction, allowing the air more time to contact the photocatalyst when passing through the photocatalyst layer. Specifically, in this embodiment, the photocatalyst layer is titanium dioxide and is coated on the inner wall of the first inclined honeycomb holes 321. In other embodiments, the photocatalyst layer may be made of other materials. The second inclined honeycomb panel 330 is disposed on the side of the first inclined honeycomb panel 320 away from the light-emitting element 200, and has several channels on it communicating with the first inclined honeycomb holes 321 and having an inclination direction opposite to that of the first inclined honeycomb holes 321. The second inclined honeycomb panel 330 cooperates with the first inclined honeycomb panel 320. The second inclined honeycomb holes 331 on the panel not only communicate with the first inclined honeycomb holes 321 but also have opposite inclination directions. This allows air to form a tortuous path as it passes through, helping to optimize airflow, increase the residence time and light-receiving area of air within the purification device, and improve purification efficiency. Simultaneously, it effectively blocks light, preventing light leakage and reducing wind resistance, thus increasing the overall airflow volume. Furthermore, the two sets of inclined honeycomb panel assemblies 300 are installed at the air inlet and outlet respectively, ensuring that air comes into contact with the photocatalyst layer twice during the purification process, further enhancing the purification effect.
[0034] In this embodiment, refer to Figures 6-8The first inclined honeycomb panel 320 includes two axially symmetrically arranged plates 322 and 323. Specifically, in this embodiment, the first inclined honeycomb holes 321 on plates 322 and 323 are inclined in opposite directions, and their inclinations are both towards the central axis 311 of the frame 310. This ensures that the light from the light-emitting element 200 can completely illuminate the inclined honeycomb holes of the two plates, and also ensures that air can be evenly dispersed throughout the entire inclined honeycomb panel, thereby increasing the chance of air contacting the photocatalyst layer and ensuring that the air is uniformly illuminated when passing through, thus improving the purification effect. Further, the second inclined honeycomb panel 330 includes a plate 332 disposed on the side of plate 322 away from the light-emitting element 200, and a plate 333 disposed on the side of plate 223 away from the light-emitting element 200 and axially symmetrically arranged with plate 332. Plates 332 and 333 are used to block light, preventing light leakage. Their double-layer arrangement with plates 322 and 323 ensures that the air, after initial treatment by the first inclined honeycomb plate 320, undergoes a second, evenly distributed photocatalytic treatment. This increases the contact time and area between the air and the photocatalyst layer, further improving the purification effect. Therefore, the axially symmetrical plate arrangement not only facilitates smooth airflow and reduces wind resistance, increasing air intake and exhaust volume, but also reduces pressure imbalances or uneven flow caused by asymmetrical arrangements. Simultaneously, it ensures more uniform illumination of the photocatalyst layer, enhancing its utilization efficiency. Because the photocatalyst on each plate receives similar illumination conditions, it ensures that pollutants in the air react with the photocatalyst as much as possible, ultimately achieving a more efficient air purification effect.
[0035] In this embodiment, refer to Figure 3 , Figure 6 and Figure 7The thickness of the first inclined honeycomb plate 320 is greater than that of the second inclined honeycomb plate 330. The thicker first inclined honeycomb plate 320 is closer to the light-emitting element 200, allowing for the coating of a larger photocatalyst layer on its inner surface. This increases the contact time and light-receiving area between the air and the photocatalyst layer, and also better reflects or scatters light from the light-emitting element 200, enabling multiple reflections within the first inclined honeycomb plate 320. This improves light utilization, ensures the photocatalyst layer is fully activated, and enhances purification efficiency. The thinner second inclined honeycomb plate 330 serves to block light leakage, further improving light utilization and reducing production costs. Specifically, in this embodiment, the photocatalyst layer also includes manganese dioxide (MnO2) coated on the inner wall of the second inclined honeycomb holes 331 of the second inclined honeycomb plate 330 to remove ozone. Manganese dioxide is an effective catalyst that promotes the decomposition reaction of ozone. When ozone comes into contact with manganese dioxide, the active sites on the manganese dioxide surface adsorb ozone molecules, causing them to decompose into oxygen and oxygen free radicals, further improving purification efficiency. In other embodiments, the inner wall of the second oblique honeycomb hole 331 may also be coated with other materials.
[0036] In this embodiment, refer to Figure 3 , Figure 6 and Figure 7 The first and second inclined honeycomb holes 321 and 331 are both tilted at 45°. This angle setting allows the inclined honeycomb panel assembly 300 in the purification device to achieve the optimal light-receiving area and the highest airflow. Because the 45° angle allows light to more evenly illuminate the inner wall of each inclined honeycomb hole, it increases the effective light-receiving area of the photocatalyst layer and helps reduce airflow resistance. Lower airflow resistance results in higher airflow. The first and second inclined honeycomb holes 321 and 331 are tilted in opposite directions (both at 45° but in opposite directions), forming an S-shaped airflow path that prolongs the residence time of air within the purification device, ensuring sufficient contact between the air and the photocatalyst layer. In other embodiments, the tilt angles of the first and second inclined honeycomb holes 321 and 331 can also be 30°, 35°, 40°, 50°, 55°, 60°, etc., as long as the tilt angles are within the range of 30°-60°, no specific limitation is made here.
[0037] In this embodiment, refer to Figure 8The housing 100 also includes: a housing body 110, a boss 120, and a clamping plate 130. The boss 120 is located on the inner side of the housing body 110 to support the inclined honeycomb panel assembly 300, providing a stable mounting base for the inclined honeycomb panel assembly 300. The clamping plate 130 is located on the upper and lower sides of the housing body 110 and works in conjunction with the boss 120 to clamp and fix the inclined honeycomb panel assembly 300. Specifically, in this embodiment, the housing body 110 also includes: a left side plate 111, a right side plate 112, a front panel 113, and a rear panel 114. The housing body 110, the two sets of inclined honeycomb panel assemblies 300, and the light-emitting element 200 constitute the entire purification device.
[0038] In this embodiment, a groove 140 is also provided on the outer side of the box body 100 for the user to lift and place the box body 110. The groove 140 is provided on the outer side of the box body 100, providing the user with an easy grip position to facilitate lifting and placing the box body 110.
[0039] In this embodiment, refer to Figure 8 The housing 100 is also equipped with a support frame 150 for installing the light-emitting element 200. Specifically, the support frame 150 is located in the middle of the housing 100, so that the light-emitting element 200 is located in the center of the entire device, ensuring that the two sets of inclined honeycomb panel assemblies 300 can be subjected to similar light intensity.
[0040] In this embodiment, the light-emitting element 200 includes at least four or more light sources. Specifically, the light-emitting element 200 consists of four UVC lamps spaced apart on the support frame 150. Using multiple light sources can significantly increase the total light intensity, ensuring sufficient ultraviolet energy to activate the photocatalyst material and improve air purification efficiency. Even if one or more light sources fail, the other light sources can continue to operate, maintaining a certain purification function. In other embodiments, the light-emitting element 200 may also be other types of lamps. Specifically, the UVC lamps of the light-emitting element 200 have a light source wavelength of 254nm ultraviolet light. In other embodiments, the UVC lamps of the light-emitting element 200 may also have other types of light source wavelengths, which are not specifically limited here.
[0041] The working principle of this utility model is roughly as follows: When the purification device is started, air is drawn into the purification device from the air inlet at the bottom of the housing 100. The airflow passes through the inclined honeycomb panel assembly 300 assembled on the air inlet, where air flows from the second inclined honeycomb panel 330 into the first inclined honeycomb panel 320 and guides the airflow toward the photocatalyst layer. The light emitted by the light-emitting element 200 irradiates the photocatalyst layer, activating the photocatalyst and generating free radicals with strong oxidizing properties on its surface. As the airflow continues to move forward, pollutants in the air come into contact with the photocatalyst layer and are decomposed into harmless substances under photocatalysis. The purified air passes through another set of inclined honeycomb panel assemblies 300 on the air outlet for further treatment, ensuring that the remaining pollutants in the air are further purified. Finally, the air is discharged from the purification device, maintaining the ambient air quality and completing the entire purification cycle.
[0042] The above is only used to illustrate the technical solution of this utility model and not to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
