Description

Technical Field

[0001] The utility model relates to the technical field of air purification equipment, in particular to an air purification device and a vehicle-mounted air purification equipment. Background Art

[0002] In order to remove dust, odor, bacteria, viruses and other microorganisms in the air, air filtration equipment is usually added indoors or in cars. Especially in the limited space of the car body, the existing technology usually installs a car air purification device in the car body.

[0003] Existing on-vehicle air purification equipment usually includes a filter element and an ultraviolet lamp that are detachably arranged in its air duct. The filter element usually adopts a filter cotton or folded filter paper structure, and the ultraviolet lamp is usually an ultraviolet mercury lamp, so as to filter and disinfect dust, odor, bacteria, viruses and other microorganisms in the air. However, this existing technology also has some shortcomings. For example, the filter cotton or folded filter paper only has a filtering effect and cannot disinfect bacteria and viruses; and the ultraviolet mercury lamp has a lot of noise and will produce ozone and UVA and UVB light that are harmful to the human body during the illumination process. Therefore, it can only be used at low power in the on-vehicle air purification equipment, and low power has a poor effect on air disinfection; and because the ultraviolet mercury lamp is linear and large in size, it is inconvenient to use in the car air duct with thickness restrictions.

[0004] Therefore, an air purification device and vehicle-mounted air purification equipment with good filtering and sterilization effects need to be designed. Utility Model Content

[0039] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0040] It should be noted that the terms "center", "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", "back", "side", "circumferential", etc. in the present utility model indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation to the present utility model. In addition, the terms such as "first" and "second" are only used to distinguish multiple components or structures with the same or similar structures, and do not represent a special limitation on the setting order or connection relationship.

[0041] Please refer to Figures 1 to 12, an embodiment of the present utility model provides an air purification device 100, which can be applied to various air purification equipment. Hereinafter, only a vehicle-mounted air purification equipment (not shown in the figure) will be taken as an example for description. The air purification device 100 includes: a housing 1, a filter element, and a photo sterilization component 3. The filter element and the photo sterilization component 3 are arranged in the housing 1 in sequence according to the air flow direction; the surface of the filter element is coated with a MOFs adsorption and catalytic coating. MOFs is the abbreviation of Metal organic Framework. The function of the housing 1 is to fix and limit the positions of the filter element and the photo sterilization component 3, and to facilitate fixing the air purification device 100 in the air duct (not shown in the figure) of various air purification equipment. Therefore, the housing 1 can be made of materials such as metal and plastic with a certain support strength. Optionally, in this embodiment, the filter element is a honeycomb filter 2, and the honeycomb filter 2 includes a plurality of honeycomb holes f arranged in an array; the honeycomb holes f are arranged along the air flow direction. Of course, in some other embodiments, the filter element can also be a HEPA filter, a tower structure filter screen, etc., as long as a MOFs adsorption and catalytic coating is applied to the surface of the filter element. The photo sterilization component 3 refers to a light irradiation component that uses light of a specific wavelength to eliminate or inhibit the growth of microorganisms, and can be an ultraviolet light irradiation component.

[0042] Since the MOFs material has a highly ordered pore structure, its pore size and surface properties can be precisely controlled, and it has metal sites that can act as Lewis acid centers and characteristics for catalyzing various chemical reactions; making the filter element have extremely strong adsorption, catalysis, air and water purification (such as removing harmful gases such as carbon dioxide, hydrogen sulfide and volatile organic compounds), and sterilization effects. Coupled with the subsequent photo sterilization component 3, the air purification device 100 has the advantages of good filtering and sterilization effects. Through product testing, the antibacterial performance of the vehicle-mounted air purification equipment with the air purification device 100 is improved to 99%, the air sterilization rate is increased to 99.9%, and the typical gas adsorption amount and efficiency are improved.

[0043] Optionally, the cross section of the honeycomb hole f is a regular hexagon, and the side length of the honeycomb hole f is greater than or equal to 2 mm and less than or equal to 10 mm. That is, the side length of the regular hexagon of the honeycomb hole f can be 2 mm, 4 mm, 6 mm, 8 mm, 10 mm; as long as the side length of the regular hexagon of the honeycomb hole f is in the range of 2 mm - 10 mm, it can ensure that the filter element has a better filtering effect.

[0044] Optionally, please refer to Figure 5 and Figure 6, in this embodiment, the light sterilization component 3 includes: a support plate 31, a power supply board 32, and multiple lamp boards 33. The support plate 31 and the power supply board 32 are arranged at intervals. In this implementation, the support plate 31 and the power supply board 32 are arranged in parallel. The power supply board 32 not only functions as the circuit board of the light sterilization component 3 but also has a supporting function; one ends of multiple spaced lamp boards 33 are inserted into the support plate 31, and the other ends are inserted into the power supply board 32. Specifically, the support plate 31 and the power supply board 32 are evenly and spacedly provided with slots g, and both ends of the lamp board 33 are inserted into the slots g of the support plate 31 or the power supply board 32. The lamp board 33 is configured with sterilization lamps 34. In this embodiment, the overall shape of the light sterilization component 3 is square, but the overall structure of the light sterilization component 3 is not limited to this. It can also be circular or other structures, which need to be designed according to the specific shapes of the air duct and the housing 1.

[0045] To improve the sterilization effect of the light sterilization component 3, reduce energy loss, and at the same time reduce the resistance of the lamp board 33 to air flow; optionally, please refer to Figure 5 and Figure 6 , in this embodiment, the lamp board 33 is arranged parallel to the air flow direction. The inner sides of adjacent two lamp boards 33, the support plate 31, and the inner side of the power supply board 32 enclose a light sterilization flow channel i. That is, in this embodiment, the light sterilization component 3 divides the housing 1 into multiple parallel light sterilization flow channels i. One of the two opposite surfaces of adjacent two lamp boards 33 is evenly configured with sterilization lamps 34, and the other surface is a high-gloss reflective surface. In this way, the light emitted by the sterilization lamps 34 on the lamp board 33 is reflected back after irradiating the high-gloss reflective surface of the contrast surface, and the air in the light sterilization flow channel i is disinfected again to improve the sterilization effect of the light sterilization component 3. Of course, in some other embodiments, the reflection effect can also be achieved by attaching a reflective film to the side of the lamp board 33 where the sterilization lamps 34 are not installed, which is not limited here. Preferably, the inner side of the support plate 31 is also a high-gloss reflective surface. Specifically, in this embodiment, the same-direction sides of multiple lamp boards 33 are configured with sterilization lamps 34, and the other side is a high-gloss reflective surface, which is convenient for the lamp boards 33 to have the same structure and is convenient for production. Optionally, the sterilization lamp 34 is a UVC ultraviolet lamp, a UVA ultraviolet lamp, a UVB ultraviolet lamp, or other ultraviolet lamps, or an ultraviolet and visible light mixed lamp; using an ultraviolet and visible light mixed lamp can not only be directly used for sterilization, but the visible light therein can also be used to increase the catalytic performance of the MOFs material; the power supply board 32 is connected to an external power supply through a connecting wire. Specifically, the connecting wire can be a LIN connecting wire 4.

[0046] To facilitate heat dissipation, optionally, in this embodiment, the lamp board 33 is an aluminum substrate, and its thickness is greater than or equal to 1.2 mm. Preferably, the thickness of the lamp board 33 is greater than or equal to 1.2 mm and less than 5 mm.

[0047] After the number of lamp boards 33 and the number of germicidal lamps 34 on the lamp boards 33 are determined, the heights of the power supply board 32 and the lamp boards 33 can be determined within a certain range. To minimize the overall thickness of the air purification device 100, optionally, please refer to Figures 7 to 12 , in this embodiment, the frame 1 includes: a concentric bottom frame 11, a middle frame 12, and an outer frame 13; the concentric bottom frame 11 includes an annular bottom plate 111 and an annular isolation plate 112; the annular isolation plate 112 is vertically disposed on one side of the annular bottom plate 111. Specifically, the annular isolation plate 112 is vertically disposed at the middle position on one side of the annular bottom plate 111 to divide the concentric bottom frame 11 into an inner filter element assembly position b and an outer light sterilization component assembly position c. Thus, the outer edge position of the filter element can be disposed in the filter element assembly position b and clamped between the filter element assembly position b and the middle frame 12. Specifically, the upper surface of the annular isolation plate 112 has a first clamping protrusion 113, and the middle frame 12 has a first clamping hole d that matches the clamping protrusion. The middle frame 12 is clamped to the first clamping protrusion 113 on the annular isolation plate 112 through the first clamping hole d to clamp the filter element between the filter element assembly position b and the middle frame 12. The light sterilization component 3 is clamped between the light sterilization component assembly position c and the outer frame 13. Specifically, the outer frame 13 has a stud 131, and the position of the light sterilization component assembly position c of the concentric bottom frame 11 corresponding to the position of the stud 131 has a through hole a. The outer frame 13 and the concentric bottom frame 11 are fixed by screws 5; at the same time, both sides of the lamp board 33 have insertion slots h, and the outer frame 13 has insertion inner edges 132 corresponding to the positions of the insertion slots h; the upper surface of the middle frame 12 has a plurality of vertically and spaced positioning tabs 121, and a positioning groove e that matches the positioning tabs 121 is provided between the insertion inner edge 132 and the outer edge of the outer frame 13; thus, while the outer frame 13 is fixed to the concentric bottom frame 11 by screws 5, the light sterilization component 3 can be clamped between the light sterilization component assembly position c and the outer frame 13 through the cooperation of the insertion inner edge 132 and the insertion slots h on the lamp board 33 and the cooperation of the positioning groove e and the positioning tabs 121. Due to the structural design of the frame 1, the filter element and the light sterilization component 3 are not simply stacked in sequence, but the support plate 31 and the power supply board 32 with a large height are sleeved outside the filter element through the annular isolation plate 112 of the concentric bottom frame 11, reducing the overall thickness of the air purification device 100.

[0048] To make the cooperation between the concentric bottom frame 11, the middle frame 12, and the outer frame 13 more stable, optionally, please refer to Figure 7 , in this embodiment, the frame 1 further includes a symmetrically arranged left half-edge outer frame 14 and a right half-edge outer frame 15. Both the left half-edge outer frame 14 and the right half-edge outer frame 15 have a U-shaped cross-section to cover at least part of the upper surface and side surface of the outer frame 13 and at least part of the bottom surface of the concentric bottom frame 11. Thus, through the clamping force of the U-shape, the cooperation between the concentric bottom frame 11, the middle frame 12, and the outer frame 13 can be made more stable.

[0049] Another aspect of the embodiment of the present utility model provides a vehicle-mounted air purification device (not shown in the figure), including an air duct, and the air purification device 100 as described above detachably disposed in the air duct. Since this vehicle-mounted air purification device has all the structures and connection relationships of the air purification device 100, therefore, it has all the advantages of the air purification device 100, which will not be elaborated here.

[0050] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
