Description
Technical Field
[0001] This utility model relates to the field of air treatment technology, and in particular to a formaldehyde purification air treatment device with a self-cleaning filter membrane. Background Technology
[0002] The self-cleaning filter membrane decomposes organic pollutants on its surface under ultraviolet light using a photocatalyst, thus achieving self-cleaning. The formaldehyde purification air treatment device automatically removes pollutants from the surface of the filter membrane, keeping the pores clear and preventing the purification efficiency from declining rapidly over time.
[0003] Existing formaldehyde-purifying air treatment devices use ultraviolet lamps installed on one side of a photocatalytic filter membrane. Ultraviolet light continuously irradiates the filter membrane, activating the photocatalyst. The activated catalyst produces highly oxidizing substances that decompose organic pollutants, achieving formaldehyde purification and self-cleaning. However, the ultraviolet lamps themselves have a limited lifespan, and their light intensity tends to weaken after prolonged use, potentially weakening the photocatalytic reaction and affecting its efficiency. In this case, the lamp needs to be replaced. Since the lamp is usually installed between the formaldehyde-purifying air treatment device and the self-cleaning filter membrane, the filter membrane must be removed sequentially before the lamp can be replaced, which is not conducive to improving the maintenance efficiency of the ultraviolet lamp.
[0004] Therefore, this application provides a formaldehyde purification air treatment device with a self-cleaning filter membrane to meet the needs. Utility Model Content
[0005] The purpose of this invention is to overcome the shortcomings of existing technologies and propose a formaldehyde purification air treatment device with a self-cleaning filter membrane.
[0006] To achieve the above objectives, this utility model adopts the following technical solution: a formaldehyde purification air treatment device with a self-cleaning filter membrane, comprising an air treatment device body, and further comprising: The self-cleaning component is placed inside the air handling unit body. The self-cleaning component includes a filter membrane frame disposed inside the air handling unit body. Side plates are provided on both sides of the filter membrane frame. An ultraviolet lamp tube is provided on the side plate near the inside of the filter membrane frame. Photocatalytic filter membranes are provided on both sides of the filter membrane frame that are perpendicular to the side plates. A fixing component is placed on the self-cleaning component and used to fix the side plate. The fixing component includes snap-fit grooves at both ends of the side plate. A snap-fit block is connected to the side of the filter membrane frame near the snap-fit groove. The side plate is snapped to the filter membrane frame through the snap-fit groove and the snap-fit block.
[0007] Furthermore, hollow limiting blocks are connected to both ends of the side plate, and nuts are fitted on both ends of the ultraviolet lamp tube near the hollow limiting blocks, with the nuts threadedly connected to the hollow limiting blocks.
[0008] The beneficial effects of adopting the above-mentioned further solution are: the nut is threadedly connected to the hollow limiting block, which facilitates the restriction of the ultraviolet lamp tube to the side plate by the cooperation of the hollow limiting block and the nut. At the same time, rotating the nut in the opposite direction separates it from the hollow limiting block, which facilitates the removal of the ultraviolet lamp tube from the side plate, thereby improving the replacement efficiency of the ultraviolet lamp tube.
[0009] Furthermore, an elastic limiting ring is provided on the inner side of the nut away from the hollow limiting block, and the nut is connected to the ultraviolet lamp tube through the elastic limiting ring.
[0010] The beneficial effect of adopting the above-mentioned further solution is that when the nut is connected to the hollow limiting block and the ultraviolet lamp is inserted inside the two, the elastic limiting ring fixes the ultraviolet lamp through its own friction, ensuring that the ultraviolet lamp remains stable after installation and preventing the ultraviolet lamp from slipping off.
[0011] Furthermore, a wiring port is provided on the top of the filter membrane frame near the side of the ultraviolet lamp tube.
[0012] The advantages of adopting the above-mentioned further solution are: it facilitates the installation of external connection wires on the ultraviolet lamp tube through the plug-in port, and facilitates the supply of power to the ultraviolet lamp tube.
[0013] Furthermore, a filter screen is provided on one side of the interior of the air handling unit body.
[0014] The beneficial effect of adopting the above-mentioned further solution is that the filtered air enters the interior of the filter membrane frame, thereby reducing the clogging of the photocatalytic filter membrane and extending its service life.
[0015] Furthermore, sealing plates are connected to both sides of the air handling unit body near the filter membrane frame inside.
[0016] The beneficial effect of adopting the above-mentioned further solution is that it allows airflow to pass only through the photocatalytic filter membrane, preventing air from bypassing the photocatalytic filter membrane and leaking out, which helps to ensure that all air is purified.
[0017] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. This utility model, by incorporating a self-cleaning component, allows for convenient replacement of the ultraviolet lamp when it ages and needs to be replaced. The filter membrane frame is pulled upwards and moved out of the air handling unit, while the side plate is pushed outwards, separating the ultraviolet lamp from the filter membrane frame. This solves the problem in traditional formaldehyde purification air handling units where the lamp is installed between the device and the self-cleaning filter membrane, requiring sequential removal of the filter membrane for replacement. This improves the maintenance efficiency of the ultraviolet lamp. Furthermore, with the ultraviolet lamp installed on both sides inside the filter membrane frame, and the photocatalytic filter membrane installed inside the frame, the ultraviolet lamps on both sides can simultaneously irradiate both sides of the photocatalytic filter membrane, ensuring the catalyst fully absorbs ultraviolet light, thereby improving formaldehyde decomposition efficiency and enhancing the device's self-cleaning function.
[0018] 2. This utility model sets up a fixing component, with the snap-fit block welded to the filter membrane frame. When the side plate is inserted into the slot of the filter membrane frame, the snap-fit block on the side plate is inserted into the snap-fit slot, allowing the two ends of the side plate to be quickly snapped and fixed with the filter membrane frame, thereby ensuring that the ultraviolet lamp tube remains stable inside the filter membrane frame, which helps to improve the stability of the ultraviolet lamp tube during use.

Detailed Implementation
[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] like Figures 1-7 As shown, this utility model provides a technical solution: a formaldehyde purification air treatment device with a self-cleaning filter membrane, including an air treatment device body 1, and further comprising: like Figures 4-5 As shown, the self-cleaning component 2 is placed inside the air handling unit body 1. The self-cleaning component 2 includes a filter membrane frame 21 disposed inside the air handling unit body 1. Side plates 22 are provided on both sides of the filter membrane frame 21. An ultraviolet lamp tube 23 is provided on the side plate 22 near the inside of the filter membrane frame 21. Photocatalytic filter membranes 27 are provided on both sides of the filter membrane frame 21 that are perpendicular to the side plate 22. like Figure 5As shown, the fixing component 3 is placed on the self-cleaning component 2 and used to fix the side plate 22. The fixing component 3 includes snap-fit grooves 31 opened at both ends of the side plate 22. A snap-fit block 32 is connected to the side of the filter membrane frame 21 near the snap-fit grooves 31. The side plate 22 is snapped into the filter membrane frame 21 through the snap-fit grooves 31 and the snap-fit block 32. By opening a groove on the filter membrane frame 21 that matches the side plate 22, when the ultraviolet lamp tube 23 ages, the filter membrane frame 21 is pulled upward and moved out of the interior of the air handling unit body 1, pushing the side plate 22 to move outward of the filter membrane frame 21, so that the side plate 22 drives the ultraviolet lamp tube 23 to separate from the filter membrane frame 21, which facilitates the replacement of the ultraviolet lamp tube 23. This solves the problem that since the lamp tube is usually installed between the formaldehyde purification air handling unit and the self-cleaning filter membrane, it is necessary to remove the filter membrane first before the lamp tube can be replaced. Replacing the tubes improves the maintenance efficiency of the ultraviolet lamp tubes 23. Simultaneously, installing the ultraviolet lamp tubes 23 on both sides inside the filter membrane frame 21, and installing the photocatalytic filter membrane 27 inside the filter membrane frame 21, allows the ultraviolet lamp tubes 23 on both sides to simultaneously irradiate the photocatalytic filter membrane 27, ensuring the catalyst fully absorbs ultraviolet light. This improves formaldehyde decomposition efficiency and enhances self-cleaning function. Furthermore, by welding the snap-fit block 32 to the filter membrane frame 21, when the side plate 22 is inserted into the slot of the filter membrane frame 21, the snap-fit block 32 is inserted into the snap-fit groove 31, facilitating the quick snap-fit of both ends of the side plate 22 onto the filter membrane frame 21 and fixing the side plate 22. This ensures the ultraviolet lamp tube 23 remains stable inside the filter membrane frame 21, improving the stability of the ultraviolet lamp tube 23 during use.
[0023] Furthermore, such as Figure 6 As shown, hollow limiting blocks 24 are connected to both ends of the side plate 22. Nuts 25 are fitted on both ends of the ultraviolet lamp tube 23 near the hollow limiting blocks 24. The nuts 25 are threadedly connected to the hollow limiting blocks 24. By welding the hollow limiting blocks 24 to both ends of the side plate 22, the ultraviolet lamp tube 23 can easily pass through the hollow limiting blocks 24 due to the hollow structure of the hollow limiting blocks 24. Then, the nuts 25 are pushed to move on the hollow limiting blocks 24, and the nuts 25 are threadedly connected to the hollow limiting blocks 24. This makes it easy to restrict the ultraviolet lamp tube 23 on the side plate 22 through the cooperation of the hollow limiting blocks 24 and the nuts 25. At the same time, rotating the nuts 25 in the opposite direction separates them from the hollow limiting blocks 24, making it easy to remove the ultraviolet lamp tube 23 from the side plate 22, thereby improving the replacement efficiency of the ultraviolet lamp tube 23.
[0024] Furthermore, such as Figure 6As shown, an elastic limiting ring 26 is provided on the inner side of the nut 25 away from the hollow limiting block 24. The nut 25 is connected to the ultraviolet lamp tube 23 through the elastic limiting ring 26. By opening a groove at one end of the nut 25 that matches the elastic limiting ring 26, it is easy to place the elastic limiting ring 26 inside the nut 25. When the nut 25 is connected to the hollow limiting block 24 and the ultraviolet lamp tube 23 is inserted inside both, the elastic limiting ring 26 fixes the ultraviolet lamp tube 23 through its own friction, ensuring that the ultraviolet lamp tube 23 remains stable after installation and preventing the ultraviolet lamp tube 23 from slipping.
[0025] Furthermore, such as Figure 5 As shown, a wire insertion port 28 is provided on the top of the filter membrane frame 21 near the ultraviolet lamp tube 23. By providing a wire insertion port 28 on the filter membrane frame 21 that matches the ultraviolet lamp tube 23, it is convenient to install external connection wires on the ultraviolet lamp tube 23 through the wire insertion port 28, and to provide power to the ultraviolet lamp tube 23.
[0026] Furthermore, such as Figures 2-3 As shown, a filter 4 is provided on one side of the interior of the air handling unit body 1. By installing the filter 4 at the air inlet, it is used to intercept large particulate pollutants. The filtered air enters the interior of the filter membrane frame 21, thereby reducing the clogging of the photocatalytic filter membrane 27 and extending its service life.
[0027] Furthermore, such as Figure 7 As shown, sealing plates 29 are connected to both sides of the air handling unit body 1 near the filter membrane frame 21. By installing the sealing plates 29 inside the air handling unit body 1 and sealing the gaps between the filter membrane frame 21 and other components, a sealed space is formed, so that the airflow can only pass through the photocatalytic filter membrane 27, preventing air from bypassing the photocatalytic filter membrane 27 and leaking out, which helps to ensure that all air is purified.
[0028] Working principle: such as Figures 1-7As shown, first connect the ultraviolet lamp 23 to an external power source using the power cord, and turn on the ultraviolet lamp 23. The ultraviolet lamps 23 on both sides simultaneously irradiate the photocatalytic filter membranes 27 on both sides, ensuring that the catalyst fully absorbs the ultraviolet light. Then, turn on the fan on the air handling unit body 1 to draw external air into the air handling unit body 1. The filter screen 4 filters the air, removing large particulate pollutants. The filtered air enters the interior of the filter membrane frame 21. At this time, the formaldehyde in the air comes into contact with the strong oxidizing substances produced by the photocatalytic filter membrane 27, purifying the formaldehyde. Finally, the purified air is discharged. When the air handling unit body 1 is used for a long time, the ultraviolet lamp 23 will age. At this time, pull the filter membrane frame 21 upward to remove the filter membrane frame 21 from the interior of the sealing plate 29, and push the side plate 22 to the outside of the filter membrane frame 21, so that the side plate 22... 2. Separate the ultraviolet lamp tube 23 from the filter membrane frame 21, rotate the nut 25 and separate it from the hollow limiting block 24, push the ultraviolet lamp tube 23 through the hollow limiting block 24 and separate it from the nut 25 and the elastic limiting ring 26, thereby replacing the ultraviolet lamp tube 23. Then, put the elastic limiting ring 26 and the nut 25 on the ultraviolet lamp tube 23 in sequence, insert one end of the ultraviolet lamp tube 23 into the hollow limiting block 24 at the bottom, and insert the other end into the hollow limiting block 24 at the top. Thread the nut 25 onto the hollow limiting block 24, and then push the elastic limiting ring 26 to move into the nut 25. The elastic limiting ring 26 fixes the ultraviolet lamp tube 23 through its own friction. Finally, reset the side plate 22 and the filter membrane frame 21 in sequence, so that the snap-fit block 32 is inserted into the snap-fit groove 31, thereby facilitating the quick snap-fit of both ends of the side plate 22 onto the filter membrane frame 21.
[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
