Description

Technical Field

[0001] The utility model relates to the field of air purification equipment, in particular to a filtering device of a water negative oxygen ion environment purifier. Background Art

[0002] Currently, most air purifiers achieve their air purification function by inserting an air filter panel into the filter channel entrance. To ensure the air filter panel's proper installation and filtration requirements, retaining ring grooves are typically provided at the filter channel entrance to accommodate the air filter panel's surrounding edges. While this approach provides adequate positioning, the filter cores of existing air filter panels are typically tightly packed, requiring the air purifier to utilize a high suction force from the fan to draw in sufficient air. This results in significant suction forces acting on the air filter panel. Because existing air filter panels are generally relatively flexible, their resistance to deformation is limited. Furthermore, since the air filter panel is only restrained around its edges, it can easily sag inward during use. This not only affects the stability of the air filter panel's installation and positioning, but also can lead to uneven density across the panel and air leakage around the panel, which can reduce the air filter panel's filtration quality and, in turn, affect the air purifier's air purification capabilities. Therefore, it is very necessary to design a filtering device for a water negative oxygen ion environment purifier to solve the above technical problems. Utility Model Content

[0003] The purpose of the present utility model is to solve the above-mentioned problems and shortcomings, and to provide a filtering device for a water negative oxygen ion environmental purifier, which can play a more stable and reliable positioning role for the air filter plate, and can avoid the deformation of the air filter plate under large suction. This not only avoids the uneven density of the air filter plate, but also greatly reduces the probability of air seepage around the air filter plate, thereby ensuring that the air filter plate has a very high filtering quality for the air, and thus can effectively improve the air purification ability of the environmental purifier.

[0004] The technical solution of the present utility model is achieved as follows:

[0005] A filtering device for a water negative oxygen ion environment purifier is characterized in that it comprises a casing, a filtering channel is opened on the casing, a positioning mesh plate is arranged in the filtering channel, and a plurality of positioning convex strips are arranged on the windward surface of the positioning mesh plate.

[0006] Preferably, a positioning ring groove is provided on the inlet edge of the filter channel.

[0007] Preferably, the positioning ridges are parallel to each other.

[0008] Preferably, the positioning mesh plate includes an integrally formed air passage plate portion and an extension plate portion, one side of the air passage plate portion is connected to one side of the extension plate portion, and both ends of each positioning ridge extend to the air passage plate portion and the extension plate portion respectively.

[0009] Preferably, a convex ring portion is provided on the inner wall of the housing, the filter channel is opened through the inner hole of the convex ring portion, and the positioning mesh plate is clamped on the convex ring portion.

[0010] Preferably, the inlet cover of the filter channel is equipped with a detachable isolation mesh plate.

[0011] Preferably, at least one insertion head is provided at one end of the isolation mesh plate, and the insertion head can be detachably inserted into the casing, and at least one magnetic positioning component is provided between the other end of the isolation mesh plate and the filter channel.

[0012] Preferably, a limiting groove is provided on the casing, a limiting protrusion is provided on the inner wall of the isolation mesh plate, the limiting protrusion can be detachably embedded in the limiting groove, and the magnetic positioning component is provided between the bottom of the limiting groove and the limiting protrusion.

[0013] Preferably, a limiting ring groove is provided on the inlet edge of the filter channel, and the surrounding side edges of the isolation mesh plate are embedded in the limiting ring groove.

[0014] Preferably, a toggle groove is provided on at least one side of the isolation mesh plate.

[0015] The present invention has the following beneficial effects: In the filtration device, a positioning screen is provided in the filter channel, and a plurality of positioning ridges are provided on the windward surface of the positioning screen. The positioning screen allows air to pass normally, and the positioning ridges are used to block the air filter plate. This not only satisfies the normal passage of air, but also reinforces the positioning screen by the positioning ridges, thereby enabling the positioning screen and the positioning ridges to provide a very stable and reliable positioning of the air filter plate, preventing deformation of the air filter plate under high suction. This not only prevents uneven density of the air filter plate, but also greatly reduces the probability of air leakage around the air filter plate, thereby ensuring high filtration quality of the air filter plate, thereby effectively improving the air purification capacity of the environmental purifier. The positioning ridges also prevent direct contact between the air filter plate and the positioning screen, thereby significantly blocking the filtration area of ​​the air filter plate by the unperforated areas of the positioning screen, thereby ensuring that the air filter plate is fully and effectively used, thereby ensuring excellent filtration performance.

[0025] like Figures 1 to 3 As shown, the filtering device of a water negative oxygen ion environment purifier described in the present invention includes a casing 1, a filtering channel 11 is opened on the casing 1, a positioning mesh plate 12 is arranged in the filtering channel 11, and a plurality of positioning ridges 13 are arranged on the windward surface 121 of the positioning mesh plate 12.

[0026] In this filter device, a positioning mesh plate 12 is provided in the filter channel 11, and a plurality of positioning ridges 13 are provided on the windward surface 121 of the positioning mesh plate 12. The positioning mesh plate 12 can allow air to pass normally, and the positioning ridges 13 can be used to block the air filter plate (not shown). This not only meets the normal passage requirements of air, but also can utilize the positioning ridges 13 to strengthen the positioning mesh plate 12, thereby enabling the positioning mesh plate 12 and the positioning ridges 13 to play a very stable and reliable positioning role on the air filter plate, which can avoid the air filter plate from deforming under high suction, and this can not only avoid the air filter plate from becoming uneven in density, but also greatly reduce the probability of air seepage around the air filter plate, thereby ensuring that the air filter plate has a very high filtration quality for air, and then can effectively improve the air purification capacity of the environment purifier. The positioning ridges 13 can also prevent the air filter plate from directly contacting the positioning mesh plate 12, so that the unopened portion of the positioning mesh plate 12 can cause a greater obstruction to the filtering portion of the air filter plate, thereby ensuring that the air filter plate can be fully and effectively used, and thus helping to ensure that the filtering performance is very good.

[0027] like Figure 2 As shown, a positioning ring groove 111 is provided on the inlet edge of the filter channel 11. The positioning ring groove 111 can be embedded around the periphery of the air filter plate, so that the positioning ring groove 111 can be used to position and enhance the sealing effect on the periphery of the air filter plate, thereby helping to further improve the filtering performance of the filter device for air.

[0028] like Figure 2 、 Figure 3 and Figure 6 Shown in Figure 1, each positioning ridge 13 is parallel to each other. This not only can facilitate manufacturing, but also can ensure that the positioning ridge 13 has a very good positioning effect.

[0029] like Figure 2 、 Figure 3 and Figure 6 As shown, the positioning ridges 13 are arranged in parallel and at equal distances, which can provide uniform, stable and reliable positioning for the air filter plate.

[0030] like Figure 6 As shown, the positioning mesh plate 12 comprises an integrally formed air passage plate portion 122 and an expansion plate portion 123. One side of the air passage plate portion 122 is joined to one side of the expansion plate portion 123, and both ends of each positioning ridge 13 extend to the air passage plate portion 122 and the expansion plate portion 123, respectively. This not only facilitates the use of a wide air filter plate to accommodate the narrow interior width of the filter channel 11, but also helps increase the filtration capacity and area, thereby further enhancing the applicability of the filtration device.

[0031] like Figure 4 and Figure 5 As shown, a convex ring portion 14 is provided on the inner wall of the housing 1. The filter channel 11 extends through the inner hole of the convex ring portion 14, and the positioning mesh plate 12 is clamped onto the convex ring portion 14. Each positioning rib 13 is disposed within the convex ring portion 14. This not only facilitates accurate and stable installation and positioning of the positioning mesh plate 12, but also facilitates a more stable and reliable positioning of the positioning mesh plate 12, and reduces the difficulty of manufacturing and installation, thereby helping to further improve the reliability and applicability of the filtration device.

[0032] To ensure the stability of the installation and positioning of the positioning grid plate 12, several screws (not shown in the figure) can be used to fix the positioning grid plate 12 on the convex ring portion 14. This can meet the requirements of stable installation of the positioning grid plate 12, so that the positioning grid plate 12 can play a more stable and reliable positioning role.

[0033] like Figure 1 and Figure 2 As shown, the inlet cover of the filter channel 11 is equipped with a detachable isolation mesh 15. The isolation mesh 15 not only meets the normal ventilation needs, but also plays a barrier role by using the isolation mesh 15 to prevent direct contact with the air filter plate, thereby enabling the air filter plate to play a more stable and reliable filtering role for a longer period of time.

[0034] like Figure 2 and Figure 7 As shown, one end of the isolation mesh 15 is provided with at least one insertion head 151, which can be removably inserted into the housing 1. At least one magnetic positioning assembly 16 is provided between the other end of the isolation mesh 15 and the filter channel 11. The insertion head 151 and the magnetic positioning assembly 16 facilitate the rapid and accurate installation and positioning of the isolation mesh 15, thereby improving the convenience of installation and removal of the isolation mesh 15.

[0035] like Figure 2 and Figure 7 As shown, the housing 1 is provided with a limiting groove 17, and the inner wall of the isolation mesh 15 is provided with a limiting protrusion 152, which is detachably mounted in the limiting groove 17. The magnetic positioning assembly 16 is disposed between the bottom of the limiting groove 17 and the limiting protrusion 152. This not only satisfies the requirement for magnetic positioning, but also utilizes the cooperation between the limiting protrusion 152 and the limiting groove 17 to make the installation and positioning of the isolation mesh 15 more accurate and stable, thereby further helping to further improve the reliability of the filtration device.

[0036] like Figures 2 to 5 、 Figures 7 to 9As shown, the magnetic positioning assembly 16 includes a magnet block 161, an iron bracket 162, and an iron part 163. The iron bracket 162 is mounted on the magnet block 161. The iron bracket 162 is fixed to the inner wall of the housing 1 by screws (not shown in the figure), and the two ends of the iron bracket 162 are inserted into the bottom of the limiting groove 17. The iron part 163 is embedded in the limiting protrusion 152 and fixed with screws (not shown in the figure). The iron part 163 can contact the two ends of the iron bracket 162. Such a magnetic positioning assembly 16 is very simple and reliable, which is not only convenient for manufacturing, but also can achieve the effect of stable positioning, thereby facilitating a more stable and reliable magnetic positioning effect.

[0037] like Figure 1 and Figure 2 As shown, a limiting annular groove 18 is provided on the inlet edge of the filter channel 11, and the four sides of the isolation mesh plate 15 are embedded in the limiting annular groove 18. This facilitates accurate and stable positioning of the isolation mesh plate 15, thereby helping to improve the stability and reliability of the installation and positioning of the isolation mesh plate 15.

[0038] like Figure 1 and Figure 2 As shown, the width of the limiting ring groove 18 is greater than the width of the positioning ring groove 111, and the positioning ring groove 111 is located inside the limiting ring groove 18. When installing the air filter plate (not shown), the air filter plate is embedded in the filter channel 11 between the positioning mesh plate 12 and the isolation mesh plate 15, and the four sides of the air filter plate are embedded in the positioning ring groove 111. The inner wall of the air filter plate is also placed against the positioning ridge 13 to achieve the required positioning of the air filter plate. If necessary, the inner wall of the isolation mesh plate 15 can be pressed against the air filter plate to further improve the stability and reliability of the air filter plate installation and positioning.

[0039] like Figure 1 and Figure 7 As shown, at least one side of the isolation mesh 15 is provided with a toggle groove 153. In this way, there is no need to set a raised handle, and the isolation mesh 15 can be disassembled by manually pulling the toggle groove 153, which not only improves the quality but also improves the convenience of use.
