In the embodiment, the fiber plate 1 is a fiber mesh in a net shape, and the surface of the fiber mesh is attached with a titanium dioxide layer (not shown in the figure), which is equivalent to that the fiber plate 1 is arranged in a laminated manner with the titanium dioxide layer.

[0035] It can be understood that the ultraviolet lamp irradiates the fiber attached with the titanium dioxide, and the ultraviolet light excites the titanium dioxide to generate electron-hole pairs to react with water molecules in the air to generate hydroxyl radicals with strong oxidizing properties, thereby achieving the effect of high-efficiency sterilization and removal of odor.

[0036] In an embodiment, the ultraviolet lamp is a lamp bead. In the embodiment, the ultraviolet lamp is a lamp strip 2 in a strip shape, and the lamp strip 2 is arranged in a side-by-side and spaced manner with the fiber plate 1, that is, the lamp strip 2 is arranged in a substantially parallel manner with the fiber plate 1.

[0037] It can be understood that the arrangement of the lamp strip increases the irradiation area of the titanium dioxide layer on the fiber plate and enhances the effect of sterilization and removal of odor.

[0038] The mounting device is used for mounting the ultraviolet lamp and the fiber plate 1. In an embodiment, the mounting device comprises two fixed strips arranged in a spaced manner, and the ultraviolet lamp and the fiber plate 1 are fixedly connected with the two fixed strips. In the embodiment, the mounting device is a surrounding frame 3 in a ring shape, the periphery of the fiber plate 1 is constrained on the inner circumferential wall of the surrounding frame 3, and the two ends of the lamp strip 2 are connected with the corresponding positions of the inner circumferential wall of the surrounding frame 3.

[0039] In an embodiment, as shown in Figures 1-3 the inner part of the surrounding frame 3 is formed with a cavity 30, and the surrounding frame 3 comprises an outer ring plate 31 and an inner ring plate 32 arranged in a spaced manner from outside to inside, and a connecting piece connecting the outer ring plate 31 and the inner ring plate 32. The inner ring plate 32 is the inner circumferential wall of the surrounding frame 3. The inner ring plate 32 is provided with an annular hole 321 extending along the circumferential direction of the inner ring plate 32, and the periphery of the fiber plate 1 is inserted into the annular hole 321, so as to realize the mounting of the fiber plate 1.

[0040] As shown in Figure 1 the embodiment, the lamp strip 2 has a plurality of lamp strips, and the plurality of lamp strips are arranged in a spaced manner along a second direction B intersecting the length direction of the lamp strip 2. In an embodiment, the second direction B intersects the length direction of the lamp strip 2 at an acute angle. In the embodiment, the plurality of lamp strips 2 are arranged in a spaced manner along a direction perpendicular to the lamp strip 2, that is, the second direction B is perpendicular to the lamp strip 2.

[0041] It can be understood that the arrangement of the plurality of lamp strips 2 increases the irradiation area and the irradiation intensity of the fiber mesh.

[0042] In an embodiment, the two ends of the lamp strip 2 are connected to the two side plates respectively arranged adjacent to the inner ring plate 32. In the embodiment, the two ends of the lamp strip 2 are connected to the two side plates respectively arranged opposite to the inner ring plate 32. That is, the first end of the lamp strip 2 is connected to one of the two side plates, and the second end of the lamp strip 2 is connected to the other of the two side plates.

[0043] In an embodiment, the connecting member is a connecting strip, and a plurality of connecting strips are arranged along the circumference of the outer ring plate 31, and the inner ring plate 32 and the outer ring plate 31 are connected by the plurality of connecting strips. In the embodiment, the connecting member is a ring plate 33 extending along the circumference of the outer ring plate 31. The ultraviolet lamp and the optical fiber plate 1 are arranged along the first direction A, and the ring plate 33 has two ring plates 33 arranged along the first direction A. The inner circumferential edge of the ring plate 33 is connected to the circumferential edge of the corresponding side of the inner ring plate 32, and the outer circumferential edge of the ring plate 33 is connected to the circumferential edge of the corresponding side of the outer ring plate 31. For example, when the first direction is the front-back direction, the inner circumferential edge of one of the ring plates 33 is connected to the front circumferential edge of the inner ring plate 32, and the outer circumferential edge of the ring plate 33 is connected to the front circumferential edge of the outer ring plate 31. The inner circumferential edge of the other ring plate 33 is connected to the rear circumferential edge of the inner ring plate 32, and the outer circumferential edge of the ring plate 33 is connected to the rear circumferential edge of the outer ring plate 31.

[0044] In order to facilitate the power supply to the ultraviolet lamp, as shown in Figure 1 , the frame 3 is provided with a positive electrode pin 41 and a negative electrode pin 42 electrically connected to the ultraviolet lamp. In the embodiment, the positive electrode pin 41 and the negative electrode pin 42 are arranged at the corners of the ring plate 33 along the second direction B. In another embodiment, the positive electrode pin 41 and the negative electrode pin 42 are arranged at other positions of the ring plate 33.

[0045] As shown in Figure 1 , the frame 3 is provided with a foolproof part 311. The presence of the foolproof part 311 avoids the air purification module from being installed in the wrong direction. In an embodiment, the foolproof part 311 is a protrusion arranged on the ring plate 33. In the embodiment, the foolproof part 311 is a notch arranged at the corner of the outer ring plate 31, and the notch is arranged spaced apart from the length direction of the positive electrode pin 41 along the diagonal line of the frame 3.

[0046] The application provides a vehicle, and the vehicle comprises a passenger cabin and an air conditioning system 5, as shown in Figures 5-8 , the air conditioning system 5 comprises a box body 51, a filter element 52 and the air purification module. That is, the air purification module is applied to the vehicle.

[0047] As shown in Figures 6-8As shown, the box 51 is provided with a cavity 510, and the box 51 is provided with an air inlet 511 and an air outlet 512 which are in communication with the cavity 510 and the passenger cabin, and the filter element 52 and the air purification module are located in the cavity 510. In an embodiment, at least part of the filter element 52 and the air purification module are arranged in sequence along the second direction, and the at least part of the filter element 52 and the air purification module are arranged in parallel. In the embodiment, the filter element 52 is provided with a groove 521 which is open towards the air purification module, and the air purification module is located in the groove 521. The air inlet 511 and the air outlet 512 are arranged in the second direction. In an embodiment, along the air flow path, the air purification module is located downstream of the filter element 52. In another embodiment, along the air flow path, the air purification module is located upstream of the filter element 52.

[0048] It can be understood that, in the external circulation, the external air is discharged into the passenger cabin through the air conditioning system 5, and the air entering the air conditioning system 5 is filtered and purified by the filter element 52 and the air purification module, that is, the impurities in the filtered air are removed at the same time as the odor in the external air is removed, so that the air entering the passenger cabin is cleaner and fresher. In the internal circulation, the filter element 52 and the air purification module filter out harmful substances and odors in the air in the vehicle, ensuring the freshness of the air in the vehicle.

[0049] In the embodiment, as shown, Figure 9 The vehicle further comprises a control module 6 and a detection module 7 for detecting the concentration of volatile organic compounds in the air in the passenger cabin, and the signal output end of the detection module 7 is electrically connected to the signal input end of the control module 6, and the control module 6 is configured to start the blowing mode of the air conditioning system 5 and turn on the ultraviolet lamp when the detection module 7 detects that the concentration of volatile organic compounds in the passenger cabin is higher than a preset value. That is, the control module 6 is electrically connected to the air conditioning system 5 and the ultraviolet lamp, and the control module 6 can control the start of the air conditioning system 5 and the turning on of the ultraviolet lamp. The blowing mode of the air conditioner adopts the existing blowing mode, and the purpose is to realize the circulation of the air in the passenger cabin. The detection module 7 is, for example, a sensor.

[0050] For example, in hot summer, after the vehicle is exposed to the sun, more harmful substances may be released in the vehicle, resulting in an increase in the concentration of volatile organic compounds; for another example, when a passenger smokes in the vehicle or uses a product with volatile chemicals, the concentration of volatile organic compounds increases, and the control module 6 will start the blowing mode of the air conditioning system 5 and the ultraviolet lamp.

[0051] When the detection module 7 detects that the concentration of volatile harmful compounds in the passenger cabin is lower than the preset value, the air conditioning system 5 and the ultraviolet lamp are in the off state. It can be understood that, at this time, energy can be saved and equipment wear and tear can be reduced.

[0052] In addition, the vehicle further comprises a display module 8 for displaying the concentration value of the volatile harmful compounds and the working state of the air purification, the display module being in signal connection with the detection module 7, and the working state of the air purification including the states of being in purification, having completed purification, being in standby, etc. The display module is, for example, a vehicle display screen.

[0053] It can be understood that the driver can clearly see the concentration value of the volatile harmful compounds in the current vehicle and the operation of the air purification system through the vehicle display screen, so as to know whether the air quality in the vehicle is good.

[0054] The technical features of the above-mentioned embodiments can be combined in any manner. In order to make the description simple, all possible combinations of the technical features in the above-mentioned embodiments are not described, however, as long as the combinations of the technical features do not exist contradictory, they should be considered as the scope of the present application.

[0055] The above-mentioned embodiments only express several implementation manners of the present application, and the description is more specific and detailed, but it should not be understood as a limitation to the patent application scope. It should be pointed out that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
