Description

Technical Field

[0001] This utility model relates to the field of air purification equipment technology, and more specifically to a long-channel disinfection module with multi-sided lighting. Background Technology

[0002] Photocatalytic disinfection technology is a disinfection and sterilization method based on the principle of photocatalytic oxidation. Its core is the generation of highly oxidizing hydroxyl radicals (·OH) and superoxide ions (O2) through the excitation of nanoscale photocatalytic materials (generally titanium dioxide) by a specific wavelength activation light source. - This technology efficiently decomposes organic pollutants and pathogenic microorganisms. Compared with traditional disinfection and sterilization methods, it has advantages such as long-lasting effect, no chemical residue, and low likelihood of drug resistance. It is a safe and reliable broad-spectrum disinfection solution, and it shows unique advantages, especially in the field of air purification.

[0003] The disinfection module is the core carrier of photocatalytic disinfection technology in the field of air purification. It activates the light source to excite the photocatalyst to produce highly oxidizing hydroxyl radicals (·OH) and superoxide ions (O2). - When airflow passes through, it dynamically and continuously disinfects the organic pollutants and pathogenic microorganisms it contains.

[0004] Chinese patent CN222747432U discloses a photocatalytic sterilization module, which includes a fan, a photocatalytic filter, and an ultraviolet light source assembly. The fan is used to introduce outside air into the photocatalytic sterilization module and finally exhaust it outward to form an air circulation flow. The photocatalytic filter includes a dense array of inclined air holes, and its surface is covered with photocatalytic microparticles, which are used to filter and trap particulate matter, bacteria, viruses and microorganisms in the air. It decomposes water and oxygen in the air through photocatalysis to form active oxygen and hydroxyl radicals, thereby decomposing bacteria, viruses, formaldehyde, TVOC organic matter in the air into water and carbon dioxide. The ultraviolet light source assembly is used to activate the photocatalytic microparticles on the surface of the photocatalytic filter and disinfect the filtered and trapped bacteria and viruses. In short, when the fan is running, it forms an airflow through the air hole array. The photocatalytic microparticles on the surface of the photocatalytic filter are excited by the ultraviolet light source assembly to generate active oxygen and hydroxyl radicals to purify the airflow.

[0005] However, the structural defects of the existing disinfection modules mentioned above are as follows:

[0006] ① The single-layer photocatalytic filter structure results in an excessively short airflow path, insufficient effective contact time between the airflow and photocatalytic microparticles, and some of the air passing through the air hole array cannot be fully disinfected;

[0007] ② The unidirectional irradiation of the ultraviolet light source component makes it difficult to ensure uniform light coverage, which also affects the disinfection effect.

[0008] To achieve the desired disinfection effect, it is often necessary to increase the module size or the number of modules, which not only increases the space occupancy rate but also significantly increases the configuration cost. This inherent defect in the structural design restricts the feasibility of applying disinfection modules in confined space scenarios. Utility Model Content

[0009] In response to the above issues, to overcome the problems of excessively short airflow paths and insufficient uniformity of the activation light source in the aforementioned photocatalytic disinfection modules, which result in insufficient disinfection of the passing air, and the need to increase the module volume or number of modules to achieve the desired disinfection effect, which not only increases the space occupancy rate but also significantly increases the configuration cost, the purpose of this utility model is to provide a disinfection module with a non-linear, meandering airflow path, which prolongs the airflow passage time and ensures uniform illumination of the activation light source, thereby ensuring sufficient air disinfection, and achieving the desired disinfection effect without increasing the scale and number of modules.

[0010] To achieve the above objectives, the technical solution of this utility model is:

[0011] A multi-sided illuminated long-channel disinfection module, comprising:

[0012] outer frame;

[0013] A light-transmitting panel assembly is located inside the outer frame. It includes several light-transmitting panels, which are arranged sequentially at intervals along the opening direction of the outer frame. At least one side of the light-transmitting panel is coated with a photocatalytic coating, and the light-transmitting panel has a flow channel array. The flow channel arrays of adjacent light-transmitting panels are staggered.

[0014] The activation light source is located inside the outer frame and at least on two sides of the outer frame, with its power line extending outward through the outer frame.

[0015] Preferably, the outer frame includes

[0016] The crossbeams consist of two sets, with the two sets of crossbeams positioned vertically opposite each other.

[0017] The end caps are in two sets, which are symmetrically placed on both sides of the two sets of crossbeams. The end caps are inserted into the crossbeams and fixed with bolts to form an outer frame.

[0018] Preferably, the end cap has a mating groove, which is inserted into the crossbeam. The crossbeam has a first rib with a connecting channel inside. A connecting hole is correspondingly opened in the mating groove. Bolts are fitted into the connecting hole and the connecting channel to lock the crossbeam and the end cap.

[0019] Preferably, a pressing portion is formed in the mating groove, which defines the end cap to the inner wall of the mating groove.

[0020] Preferably, the crossbeam has a second rib corresponding to the light-transmitting plate. The second rib has a transverse groove. The second ribs of the two sets of crossbeams are inserted into the upper and lower side edges of the corresponding light-transmitting plates through the transverse grooves. The crossbeam corresponding to the activated light source is located between adjacent second ribs.

[0021] Preferably, the mating groove has a snap-fit ​​part corresponding to the light-transmitting plate, and the snap-fit ​​part has a longitudinal snap-fit ​​groove. The snap-fit ​​parts of the two sets of end caps are inserted into the left and right side edges of the corresponding light-transmitting plates through the longitudinal snap-fit ​​groove.

[0022] Preferably, the activation light source is a visible light activation light source, and the wavelength of the visible light emitted after being powered on is greater than or equal to 400nm.

[0023] Preferably, the activation light source is located on two opposite sides of the outer frame.

[0024] Preferably, both sides of the light-transmitting panel are coated with a photocatalytic coating.

[0025] Preferably, the photocatalytic coating is a nano-titanium dioxide coating.

[0026] Compared with the prior art, the advantages of this utility model are:

[0027] (1) The flow channel arrays of adjacent light-transmitting plates are misaligned. When the airflow passes through the flow channel array of the upstream light-transmitting plate, the downstream light-transmitting plate will act as a guide, guiding the airflow to detour forward, thereby extending the flow channel length and increasing the time for the airflow to stay and be disinfected in the installation cavity.

[0028] (2) The activation light source is located at least on two sides of the outer frame. When powered on, the activation light source is lit to form multi-directional three-dimensional illumination. By supplementing light from multiple angles, the blind spots in the illumination are eliminated, and the uniformity of the light distribution is achieved. At the same time, due to the airflow delay through the mounting cavity, the photocatalyst coating is fully excited, enhancing the strong oxidizing properties of hydroxyl radicals (·OH) and superoxide ions (O2). - The generation efficiency ensures the efficient elimination of organic pollutants and pathogenic microorganisms in the airflow.

[0029] (3) This application overcomes the drawback of needing to expand the module volume or increase the number of modules to achieve the same disinfection effect by improving the disinfection effect of a single disinfection module. It not only reduces the space occupancy rate, but is also more suitable for application in confined space scenarios, and will also greatly reduce the configuration cost. Attached Figure Description

Any embodiment or design described as "exemplary" or "for example" in this application should not be construed as being more preferred or advantageous than other embodiments or designs.

[0046] As mentioned in the background technology, the disinfection module is the core carrier of photocatalytic disinfection technology in the field of air purification. The activation light source 3 excites the photocatalyst to generate highly oxidizing hydroxyl radicals (·OH) and superoxide ions (O2). -When airflow passes through, it dynamically and continuously disinfects the organic pollutants and pathogenic microorganisms contained therein. Existing disinfection modules include a fan, a photocatalytic filter, and an ultraviolet light source component. The photocatalytic filter includes a dense array of inclined air holes, and its surface is covered with photocatalytic microparticles. When the fan runs, it forms an airflow through the air hole array. The photocatalytic microparticles on the surface of the photocatalytic filter are excited by the ultraviolet light source component to generate active oxygen and hydroxyl free radicals to continuously purify the airflow. However, because the photocatalytic filter is a single-layer structure, the airflow path is too short, which shortens the effective contact time between the airflow and the photocatalytic microparticles. As a result, some air cannot be fully disinfected. Moreover, the unidirectional irradiation of the ultraviolet light source component cannot guarantee the uniformity of illumination, which will further affect the disinfection effect. In order to achieve the expected disinfection effect, it is necessary to increase the module volume or increase the number of modules, which not only increases the space occupancy rate, but also significantly increases the configuration cost. This inherent defect in structural design mainly restricts the feasibility of applying the disinfection module in confined space scenarios.

[0047] like Figure 1 and Figure 2 As shown, based on this, this application provides a multi-sided lighting long flow channel disinfection module, which needs to be used with a fan. The fan generates airflow to disinfect organic pollutants and pathogenic microorganisms in the airflow. It includes an outer frame 1, a light-transmitting plate group 2, and an activation light source 3.

[0048] The shape of the outer frame 1 is not particularly limited and can be any shape such as rectangle or circle as needed. The hollow interior space of the outer frame 1 serves as an installation cavity for installing the light-transmitting plate assembly 2 and the activation light source 3. At the same time, it provides rigid support for the light-transmitting plate assembly 2 and the activation light source 3 to maintain installation stability. The installation cavity has two openings, which can be arranged in a coaxial opposite layout or an offset opposite layout, allowing airflow to enter the installation cavity from one opening and flow back to the external space from the other opposite opening.

[0049] like Figures 1 to 3 As shown, the light-transmitting plate assembly 2 includes a number of light-transmitting plates 2a. The light-transmitting plates 2a are made of semi-transparent or fully transparent material to allow the light beam to pass through smoothly when the activation light source 3 is lit. At least one side of the light-transmitting plate 2a is coated with a photocatalytic coating (not shown in the attached figure). The photocatalytic coating is a film layer composed of nano-sized photocatalytic particles. When the activation light source 3 is lit, the photocatalytic coating will be directly excited to generate strongly oxidizing hydroxyl radicals (·OH) and superoxide ions (O2). -To improve the adhesion of the photocatalyst coating, a light-transmitting plate 2a with a high surface roughness is preferred. The dense micro-slits and uneven structure formed on the surface of this type of light-transmitting plate 2a will provide more adhesion points for the photocatalyst particles, increasing the actual contact area between the light-transmitting plate 2a and the photocatalyst coating, thereby improving the adhesion effect. The light-transmitting plates 2a are arranged sequentially at intervals along the opening direction of the mounting cavity of the outer frame 1. The space between adjacent light-transmitting plates 2a is a wind cavity. Each light-transmitting plate 2a is provided with a flow channel hole composed of several flow channel holes. The external space and each air cavity are connected to each other through the flow channel array 201 to ensure that the airflow flows smoothly between the two openings of the installation cavity. The flow channel arrays 201 of the adjacent light-transmitting plates 2a are staggered, and the fan is placed on one side of the light-transmitting plate group 2 of the disinfection module of this application. When the airflow generated by the fan passes through the flow channel array 201 of the upstream light-transmitting plate 2a, the downstream light-transmitting plate 2a will play a guiding role, guiding the airflow to detour forward, thereby extending the flow channel length and increasing the residence time and disinfection time of the airflow in the installation cavity.

[0050] like Figure 2 As shown, the activation light source 3 is located on at least two sides of the outer frame 1. Its power line (not shown in the attached figure) extends outward through the outer frame 1 to connect to an external power source. When powered on, the activation light source 3 is illuminated to form multi-directional three-dimensional illumination. By supplementing light from multiple angles, blind spots in the illumination are eliminated, achieving uniformity in the light distribution. At the same time, due to the airflow delay through the mounting cavity, the photocatalyst coating is fully excited, enhancing the activity of highly oxidizing hydroxyl radicals (·OH) and superoxide ions (O2). - This application improves the efficiency of the generation of disinfection modules, ensuring efficient disinfection of organic pollutants and pathogenic microorganisms in the airflow. By improving the disinfection effect of a single disinfection module, it overcomes the drawback of currently requiring an increase in module volume or number of modules to achieve the same disinfection effect. This not only reduces space occupancy but is also more suitable for applications in confined space scenarios and will significantly reduce configuration costs.

[0051] like Figures 1 to 7 As shown, the outer frame 1 is a split structure, consisting of two parts: a crossbeam 1a and an end cap 1b. There are two sets of crossbeams 1a and two sets of end caps 1b. The two sets of crossbeams 1a are positioned opposite each other, and the two sets of end caps 1b are placed on the left and right sides of the two sets of crossbeams 1a. The end caps 1b and crossbeams 1a are first connected by a plug-in method to achieve tool-free pre-positioning, and then bolts 4 are screwed in to lock and fix them. The locking force of the bolts 4 makes the crossbeams 1a and end caps 1b firmly connected, thus forming the outer frame 1, which provides stable rigid support for the light-transmitting plate group 2 and the activation light source 3. In addition, the split structure of the outer frame 1 will also improve the convenience of maintenance of the light-transmitting plate group 2 and the activation light source 3. Only the crossbeams 1a and end caps 1b need to be disassembled, avoiding the overall disassembly of the outer frame 1.

[0052] like Figure 2 , Figures 4 to 9As shown, the crossbeam 1a has second ribs 103, which are arranged along the length of the crossbeam 1a and are equal in number to the light-transmitting plates 2a, and correspond to each other. The second ribs 103 have through transverse slots 103a. The second ribs 103 of the two sets of crossbeams 1a are inserted into the upper and lower side edges of the corresponding light-transmitting plates 2a through the transverse slots 103a. The light-transmitting plates 2a can be installed by inserting their left or right side edges into one end of the transverse slots 103a and moving along the transverse slots 103a, or by directly inserting their upper and lower side edges into the transverse slots 103a of the second ribs 103 of the two crossbeams 1a. After installation, The upper and lower sides of the light-transmitting plate 2a are positioned by two crossbeams 1a to achieve balanced support, thereby keeping the relative position of each light-transmitting plate 2a stable. The activation light source 3 is positioned in the space between adjacent second ribs 103, corresponding to the crossbeams 1a. In this application, the activation light source 3 is installed in the space by adhesive bonding, but it is not limited to this method of fixation. At the same time, it is used in conjunction with the stop and limit of the second ribs 103 to achieve stable positioning of the activation light source 3. It can be understood that the activation light source 3 forms a symmetrical layout with the crossbeams 1a on the upper and lower sides of the outer frame 1, thereby forming three-dimensional illumination when powered on, effectively eliminating the illumination blind zone and achieving uniformity of light distribution.

[0053] like Figure 4 , Figure 5 and Figure 9 As shown, the mating groove 101 has a snap-fit ​​part 105 corresponding to the light-transmitting plate 2a. The snap-fit ​​part 105 has a longitudinal snap-fit ​​groove 105a. The snap-fit ​​parts 105 of the two sets of end caps 1b are inserted into the left and right side edges of the corresponding light-transmitting plate 2a through the longitudinal snap-fit ​​groove 105a. After the upper and lower side edges of the light-transmitting plate 2a are fixed by the crossbeam 1a, the two end caps 1b are moved in opposite directions. When the crossbeam 1a is snapped into the mating groove 101 of the end cap 1b, the longitudinal snap-fit ​​groove 105a of the snap-fit ​​part 105 will also be inserted into the light-transmitting plate 2a. In this way, the light-transmitting plate 2a will be stably held in the preset position, thereby reducing the risk of displacement and deformation caused by external force. It should be mentioned that there is at least one set of snap-fit ​​parts 105 corresponding to each light-transmitting plate 2a. This will increase the area of ​​the mating position between the end cap 1b and the light-transmitting plate 2a, and further improve the installation stability.

[0054] like Figures 4 to 9As shown, the end cap 1b has a mating groove 101, which is located on the side of the end cap 1b near the crossbeam 1a. The width of the crossbeam 1a matches the mating groove 101 to achieve insertion and positioning. The side wall of the mating groove 101 restricts the horizontal movement of the crossbeam 1a. The crossbeam 1a has a through first rib 102, which is arranged along the length of the crossbeam 1a. A connecting hole 101a is correspondingly opened in the mating groove 101. The connecting hole 101a communicates with the connecting channel 102a. The bolt 4 is fitted into the connecting hole 101a and the connecting channel 102a, thereby locking the crossbeam 1a and the end cap 1b together. During installation, the crossbeam 1a is first inserted into the mating groove 101 of the end cap 1b for pre-positioning, and then locked and fixed by the bolt 4. This not only ensures the assembly accuracy but also enhances the structural stability.

[0055] like Figure 4 , Figure 5 and Figure 9 As shown, a pressing part 104 is formed in the joint groove 101. The pressing part 104 is arranged close to the side wall of the joint groove 101, and a slot for pre-installing the crossbeam 1a is formed between it and the inner wall of the joint groove 101. After the crossbeam 1a is inserted into the joint groove 101, it is constrained by the pressing part 104 and is limited to the inner wall of the joint groove 101. It fits tightly with the inner wall of the joint groove 101, thereby restricting the movement of the crossbeam 1a in the vertical direction. With the limiting of the side wall of the joint groove 101, the crossbeam 1a is pre-positioned with high precision.

[0056] Furthermore, the activation light source 3 is a visible light activation light source 3. When powered on, it emits an activation beam of visible light with a wavelength greater than or equal to 400nm. Compared to ultraviolet laser beams, its wavelength is in the same spectrum as ambient light, thus avoiding physical damage such as corneal burns and skin cancer caused by prolonged exposure to ultraviolet radiation.

[0057] like Figure 2 As shown, the activation light source 3 is located on two opposite sides of the outer frame 1. When the activation light source 3 is powered on, it will form a three-dimensional illumination, effectively eliminating the illumination blind zone and achieving uniformity of light distribution.

[0058] Furthermore, both sides of the light-transmitting plate 2a are coated with a photocatalytic coating, thereby doubling the reaction area and improving the utilization rate of the activation beam. When the activation beam penetrates the light-transmitting plate 2a, it can fully stimulate the photocatalytic coatings on both sides to generate hydroxyl radicals (·OH) and superoxide ions (O2). - At the same time, it disinfects organic pollutants and pathogenic microorganisms in the airflow on both sides of the light-transmitting plate 2a, achieving a three-dimensional purification effect and avoiding the shadow effect caused by single-sided spraying.

[0059] Furthermore, the photocatalytic coating is a nano-titanium dioxide coating, which has broad-spectrum catalytic activity, can be excited by visible light activation source 3, and has good chemical stability and strong oxidation ability.

[0060] It should be understood that the various forms of processes shown above can be used to rearrange, add, or delete steps. For example, the steps described in this application can be executed in parallel, sequentially, or in different orders, as long as the desired result of the technical solution disclosed in this application can be achieved, and this is not limited herein.

[0061] The embodiments and descriptions above are merely illustrative of the principles and preferred embodiments of this application. Various changes and modifications may be made to this application without departing from the spirit and scope thereof, and all such changes and modifications fall within the scope of this application as claimed.
