[0002] In order to remove dust, odor, bacteria, viruses and other microorganisms in the air, air filtering equipment is usually installed indoors or in cars. Especially in cars with limited space, air purification equipment is usually built into the car in the prior art.

[0003] Existing air purification equipment typically only uses filter elements in their air ducts to filter and absorb dust and odors from the air. However, this existing technology also has some shortcomings. The filter element only has a filtering effect and cannot eliminate bacteria and viruses. Furthermore, installing a germicidal lamp above the filter element not only increases the filter volume, but also blocks the airflow, increasing air resistance and affecting the filter flow. Utility Model Content

[0004] The purpose of the utility model is to address the defects and shortcomings of the existing technology and provide a vehicle-mounted air purification structure with a replaceable filter element, which has the advantages of small size, good filtering and sterilization effect, small air resistance and a large sterilization range.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a vehicle-mounted air purification structure with a replaceable filter element, comprising:

[0006] frame;

[0007] A filter element is detachably mounted on the inner side of the frame, wherein MOFs material is provided in the filter element to perform adsorption and catalytic filtration on the air;

[0008] The light sterilization component is arranged on the inner peripheral side of the frame and above the filter element, and irradiates toward the inner side of the frame.

[0009] The present invention is further provided with a sterilization assembly comprising: a plurality of sterilization lamps distributed on the inner circumference of the frame and a lamp panel for mounting the sterilization lamps.

[0010] The utility model is further provided with a blocking edge extending toward the inner side of the frame, provided on the inner peripheral side of the frame, between the filter element and the light sterilization component;

[0011] The blocking edge is provided with an irradiation opening corresponding to the germicidal lamp for the germicidal lamp to be exposed for irradiation.

[0012] The utility model further provides that the filter element includes: a bottom layer, a filter paper layer, and MOFs material and activated carbon material arranged between the bottom layer and the filter paper layer.

[0013] The utility model is further provided that the germicidal lamp is a UVC ultraviolet lamp, a UVA ultraviolet lamp, a UVB ultraviolet lamp or a mixed ultraviolet and visible light lamp.

[0014] The utility model is further provided with a silicone protective sleeve on the outside of the germicidal lamp.

[0015] The present invention is further configured such that a plurality of the germicidal lamps are evenly distributed on four sides of the inner periphery of the frame.

[0016] The present invention is further provided that the lamp board is an aluminum substrate, and the thickness of the lamp board is greater than or equal to 1.3 mm.

[0017] The utility model is further provided that the filter element is formed by splicing several sub-filter elements of the same size along the width direction;

[0018] A disassembly opening is provided on the peripheral side of the frame body, and the width of the disassembly opening is greater than the width of the sub-filter element so that the sub-filter element can be taken out of or installed in the disassembly opening.

[0019] The present invention is further provided that the frame includes: a lower frame, an upper frame detachably mounted above the lower frame, and an outer frame detachably mounted on the outer sides of the upper frame and the lower frame, and the light sterilization component is arranged between the upper frame and the lower frame.

[0020] After adopting the above technical solution, the beneficial effects of the utility model are:

[0021] 1. In the present invention, MOFs material is provided in the filter element, which can capture a large number of fine particles through electrostatic adsorption. The light sterilization component irradiates from the four sides of the frame to the inner side of the frame to disinfect and sterilize the air passing through the inner side of the frame, and cooperates with the filter element to achieve a good filtering effect. The light sterilization component is arranged on the inner side of the frame and will not purify the filter flow of the structure. MOFs material also has the ability to catalyze under light, so that the light sterilization component can irradiate the air inside the frame for sterilization while also irradiating the filter element, and catalyze the MOFs material in the filter element to decompose the harmful organic matter on the filter element into carbon dioxide and water, so as to avoid these harmful substances from remaining and accumulating on the filter element, causing secondary pollution to the air and affecting the effect and service life of the filter element.

[0022] 2. In the present invention, a blocking edge extending and protruding toward the inner side of the frame is provided between the inner peripheral side of the frame and the filter element and the light sterilization component. The blocking edge can prevent the filter element from sliding upward, thereby preventing the filter element from blocking the sterilization lamp, which in turn causes the sterilization lamp to be unable to directly irradiate the air inside the frame and lose the effect of irradiation and sterilization; an irradiation port corresponding to the sterilization lamp is provided on the blocking edge for the sterilization lamp to be exposed. While not blocking the sterilization lamp from irradiating the air inside the frame, the sterilization lamp can also better irradiate the filter element below, so as to disinfect the surface of the filter element and photocatalyze the MOFs material, thereby achieving a good disinfection effect.

DETAILED DESCRIPTION

[0030] The present invention will be described in further detail below with reference to the accompanying drawings.

[0031] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but as long as they are within the scope of the claims of the present invention, they are protected by patent law.

[0032] This embodiment relates to a vehicle-mounted air purification structure with a replaceable filter element, such as Figure 1-5 As shown, it includes: a frame 100, a filter element 200 and a light sterilization component 300.

[0033] In this embodiment, the application of the air purification structure in an air conditioner is used as an example for explanation. In other embodiments, the air purification structure can also be applied to other equipment and usage scenarios to achieve a good air purification effect. The air duct of the application equipment can also be directly used as the frame 100 of the air purification structure.

[0034] Filter element 200 is installed inside frame 100 to filter and adsorb air passing through the purification structure. MOFs (Metal Organic Framework) material is provided inside filter element 200. MOFs material is composed of an organic skeleton and metal ions and has porous crystalline properties. It can capture a large number of fine particles through electrostatic adsorption, effectively filtering PM2.5 and other pollutants in the air, achieving good filtration effect. Filter element 200 is detachably installed inside frame 100 and can be disassembled, cleaned, or replaced to maintain the purification structure's good filtration effect and improve its sustainable use.

[0035] The light sterilization component 300 is arranged on the inner circumference of the frame 100 and is located above the filter element 200. The light sterilization component 300 irradiates the inner side of the frame 100 from all sides to disinfect and sterilize the air passing through the inner side of the frame 100, and cooperates with the filter element 200 to achieve a good filtering effect. Because the light sterilization component 300 is arranged on the inner circumference of the frame, the light sterilization component 300 does not block the air flow inside the frame 100 and increase the resistance to air flow, affecting the filtration flow of the purification structure. The MOFs material also has the ability to catalyze under light, so that the light sterilization component 300 can irradiate the air inside the frame 100 for sterilization while also irradiating the filter element 200, catalyzing the MOFs material in the filter element 200 to decompose harmful organic matter on the filter element 200 into carbon dioxide and water, preventing these harmful substances from remaining and accumulating on the filter element 200, causing secondary pollution to the air and affecting the effect and service life of the filter element 200. At the same time, the light sterilization component 300 does not need to occupy too much space when it is arranged on the inner peripheral side of the frame 100, making the volume of the purification structure more compact.

[0036] In this embodiment, the light sterilization assembly 300 includes: a plurality of germicidal lamps 310 distributed on the inner periphery of the frame 100, and a lamp panel 320 for mounting and fixing the germicidal lamps 310. The light is irradiated from all sides of the inner periphery of the frame 100 to the central portion of the inner periphery of the frame 100, ensuring the coverage and uniformity of the light, thereby achieving good disinfection and sterilization effects and photocatalytic effects. The germicidal lamps 310 are evenly distributed on all sides of the inner periphery of the frame 100, so that the energy of the germicidal lamps 310 is concentrated in the center of the inner periphery of the frame 100, ensuring good irradiation and sterilization effects. As a preferred embodiment, the germicidal lamps 310 are UVC ultraviolet lamps, UVA ultraviolet lamps, UVB ultraviolet lamps, or ultraviolet and visible light hybrid lamps; the use of ultraviolet and visible light hybrid lamps can not only be used directly for sterilization, but the visible light therein can also increase the catalytic properties of the MOFs material. Of course, in other embodiments, the light sterilization assembly 300 may also be configured as other structures to achieve a good light irradiation sterilization effect, such as a light strip being installed around the inner circumference of the frame 100 .

[0037] As a preferred solution, the lamp board 320 is configured as an aluminum substrate with a thickness greater than or equal to 1.3 mm and a length greater than 50 mm. This provides a secure mounting surface for the germicidal lamp 310, allowing for effective heat dissipation from the lamp board 320 and ensuring stable operation. In this embodiment, a silicone protective sleeve 330 is also provided on the exterior of the germicidal lamp 310 to protect it from moisture and particulate matter in the filtered air, potentially damaging or rendering it inoperable. This improves the operational stability of the germicidal lamp 310.

[0038] In this embodiment, a blocking edge 140 extending toward the inside of the frame 100 is provided on the inner circumference of the frame 100, between the filter element 200 and the light sterilization assembly 300. The blocking edge 140 can prevent the filter element 200 from sliding upward, preventing the filter element 200 from blocking the germicidal lamp 310, thereby preventing the germicidal lamp 310 from directly irradiating the air inside the frame 100, causing the germicidal lamp 310 to lose its irradiation and sterilization effect, and affecting the filtration and purification effect of the purification structure. As a preferred solution, an irradiation port 141 corresponding to the germicidal lamp 310 is provided on the blocking edge 140 to expose the germicidal lamp 310. While not blocking the germicidal lamp 310 from irradiating the air inside the frame 100, the germicidal lamp 310 can also better illuminate the filter element 200 below, thereby disinfecting the surface of the filter element 200 and photocatalyzing the MOFs material, achieving a good disinfection effect. The irradiation port 141 can guide the irradiation angle of the germicidal lamp 310 to ensure good coordination between the multiple germicidal lamps 310 and achieve a uniform irradiation effect.

[0039] As a preferred solution, the filter element 200 includes: a bottom layer, a filter paper layer, and a MOFs material and an activated carbon material arranged between the bottom layer and the filter paper layer to ensure that the filter element 200 has a good filtering and adsorption effect. The filter element 200 is pleated to increase the filtering area and improve the filtering efficiency. In this embodiment, the filter element 200 is spliced ​​together by several sub-filter elements 210 of the same size along the width direction. A disassembly port 150 is provided on the wide side of the frame 100. The width of the disassembly port 150 is slightly larger than the width of a single sub-filter element 210 so that the sub-filter element 210 can be taken out or loaded from the disassembly port 150 to facilitate the replacement of the filter element 200. Of course, in other embodiments, the filter element 200 can also be a whole piece, embedded and installed on the inner circumference of the frame 100 to ensure a good filtering effect. The filter element 100 can be disassembled by pushing the filter element 200 directly along the direction of the frame 100.

[0040] In this embodiment, a control circuit board 500 is also disposed inside the frame 100. This control circuit board 500 is electrically connected to the light sterilization assembly 300, providing power to the light sterilization module and controlling the light sterilization module's operating mode. This allows the operating power of the germicidal lamp 310 to be adjusted to suit different usage scenarios. As a preferred solution, a connection cable 400 is provided on the control circuit board 500. The vehicle's onboard computer is electrically connected to the control circuit board 500 via the connection cable 400, providing power and sending control signals to the control circuit board 500. The control circuit board 500 adjusts the light sterilization module's operating mode based on these control signals and displays the operating status of the germicidal lamp on the onboard computer. For example, when the filtration flow rate is low, the control circuit board 500 operates in normal mode, controlling the germicidal lamp 310 to operate at 70% power, achieving energy-saving operation of the purification structure. When the filtration flow rate is high, the control circuit board 500 operates in strong sterilization mode, controlling the germicidal lamp 310 to operate at 100% power, achieving a strong sterilization effect and meeting the sterilization requirements of large flow rates. The connecting line 400 is preferably a LIN communication line to achieve good signal transmission effect.

[0041] As a preferred embodiment, the frame 100 includes a lower frame 110, an upper frame 120 detachably mounted above the lower frame 110, and an outer frame 130 detachably mounted outside the upper and lower frames 120, 110. The outer frame 130 wraps around the upper and lower frames 120, 110, enhancing the mounting stability of the upper and lower frames 120, 110. The upper and lower frames 120, 110 are connected to each other using a snap-fit ​​mechanism. The light sterilization assembly 300 and the control circuit board 500 are both disposed between the upper and lower frames 120, 110, protecting them from damage caused by external contact. The detachable structure of the upper and lower frames 120, 110 also facilitates maintenance and replacement of the light sterilization assembly 300 and the control circuit board 500.

[0042] In this embodiment, a label chip is provided on the filter element 200, and a chip identification module for identifying the label chip is provided on the circuit control board. When the filter element 200 is installed on the purification structure, the chip identification module on the circuit control board can obtain information about the filter element 200 by identifying the label chip, including but not limited to: brand, type, production date, etc., so as to understand the condition of the filter element 200. The car computer is electrically connected to the control circuit board 500 via a connecting line 400, and uses the filter element 200 information read by the chip identification module. As a preferred solution, a timing module is also provided on the control circuit board 500. The timing module cooperates with the chip identification module to record the usage time of the filter element 200. The car computer can read the usage time of the filter element 200 to analyze the service life of the filter element 200 for the user's reference and to remind the user to replace it, which is more intelligent and convenient.

[0043] The above is only used to illustrate the technical solution of the present invention and is not intended to limit it. Other modifications or equivalent substitutions made to the technical solution of the present invention by ordinary technicians in this field should be included in the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solution of the present invention.
