[0019] The present invention will be further described in detail below with reference to the accompanying drawings.

[0020] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive element, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.

[0021] This embodiment relates to an air guiding component, such as... Figure 1-3 As shown, it includes: a first separator 4, which is installed at the air outlet of the vehicle air conditioner and abuts against the filter element 2. The first separator 4 is used to separate the internal circulation air outlet and the external circulation air outlet of the vehicle air conditioner, and guides the internal circulation air and the external circulation air blown out by the vehicle air conditioner into the filter element 2. The filter element 2 is a filter element, and there is at least one filter element. The first separator 4 guides the internal circulation air and the external circulation air blown out by the vehicle air conditioner into the filter element 2 respectively. By filtering the blown air through the filter element 2, the internal circulation air and the external circulation air blown out by the vehicle air conditioner can be accurately delivered into the filter element 2 with the use of the air guiding assembly, avoiding the situation where the air blown out from the internal circulation air outlet and the external circulation air outlet crosses before filtration.

[0022] Specifically, the first partition 4 is a ring-shaped partition frame used to enclose the internal circulation air outlet duct.

[0023] like Figure 1 As shown, it also includes a sterilization component 5, which is installed on the first partition 4 and is used for air sterilization on both the inner and outer sides of the first partition 4. Specifically, the sterilization component 5 includes multiple sterilization lamps 51, which are installed on both the inner and outer sides of the partition. The UVC ultraviolet light emitted by the sterilization lamps 51 can sterilize the internal and external air circulation air blown out by the vehicle's air conditioning system, providing air purification.

[0024] This utility model also provides an air purification device, such as Figure 1-5As shown, the device includes: a housing 1, a filter element 2, and the aforementioned air guide assembly. The housing 1 is installed at the air outlet of the vehicle's air conditioning system. The first partition 4 is installed at the air inlet inside the housing 1. The filter element 2 is installed at the air outlet inside the housing 1, with the first partition 4 abutting against the filter element 2. The filter element 2 is a filter cartridge, and at least one filter cartridge is provided. The filter element 2 is used to filter the air exhausted from the vehicle's air conditioning system. Because this air purification device includes the air guide assembly, it also possesses the advantages and effects of the air guide assembly, which will not be elaborated here. In addition, the sterilization component 5 is installed on the first partition 4 instead of on the inner wall of the housing 1. The sterilization component 5 does not occupy the space around the inside of the housing 1, and will not reduce the installation space of the filter element 2 or obstruct the filter element 2, thus ensuring the filtration efficiency of the filter element 2 for the airflow.

[0025] Furthermore, the housing 1 is installed on the air outlet cover 3 of the vehicle air conditioner. The air outlet cover 3 has a first air outlet 31 and a second air outlet 32. The first air outlet 31 and the second air outlet 32 ​​correspond to the internal circulation air outlet duct and the external circulation air outlet duct of the vehicle air conditioner, respectively. The first partition 4 is used to surround the first air outlet 31 on the air outlet cover 3.

[0026] like Figure 1 As shown, multiple mounting plates 33 are fixed on the air outlet cover 3. The first partition 4 is installed between the multiple mounting plates 33. At least one slot 34 is opened inside the air outlet cover 3. At least one locking block 41 is fixed on the first partition 4, and the locking block 41 is engaged in the slot 34. When installing the first partition 4, it is aligned with the multiple mounting plates 33 and then moved horizontally into the air outlet cover 3. The first partition 4 will be embedded in the multiple mounting plates 33, and at the same time, the locking block 41 will be engaged in the slot 34, so that the first partition 4 is stably installed on the air outlet cover 3.

[0027] Furthermore, a shock-absorbing plate 6 is provided between the mounting plate 33 and the first partition 4, and between the card block 41 and the card slot 34. The shock-absorbing plate 6 can fill the gap between the first partition 4 and the air outlet cover 3, and can absorb the noise generated by the vibration of the first partition 4 when the vehicle air conditioner blows air.

[0028] A second partition 7 is installed at the air outlet end of the casing 1. The second partition 7 is tightly connected to the filter element 2, and the second partition 7 is set in correspondence with the first partition 4. The second partition 7 is a partition frame. The air filtered by the filter element 2 can still be separated by the second partition 7 to ensure that the internal and external circulating air after filtration does not leak.

[0029] The working principle is as follows: The vehicle is equipped with an in-vehicle air conditioner. The housing 1 is detachably connected (by snap-fit, embedding, bolt connection, etc.) to the air outlet cover 3 of the in-vehicle air conditioner. When the in-vehicle air conditioner is simultaneously in internal and external circulation mode and / or external circulation mode, the air blown out from the internal circulation air outlet of the in-vehicle air conditioner will pass through the second air outlet 32 ​​and enter the first partition 4. The air blown out from the external circulation air outlet of the in-vehicle air conditioner will pass through the first air outlet 31 and enter the housing 1 and the area outside the first partition 4. The UVC ultraviolet rays emitted by multiple germicidal lamps 51 can sterilize the airflow inside and outside the first partition 4, providing air purification. The separated air will be guided by the first partition 4 to the filter 2, preventing the air blown out from the internal and external circulation air outlets from mixing before filtration. The filter 2 will filter the air inside it. Finally, the filtered air is separated by the second partition 7 to ensure that the filtered internal and external circulation air outlets do not mix.

[0030] The use of housing 1, filter element 2, first separator 4, and second separator 5 effectively prevents airflow from the internal and external circulation ducts of the vehicle air conditioner from flowing between the ducts before and after filtration. Furthermore, the filter element 2 is mounted on the air outlet cover 3 of the vehicle air conditioner via housing 1, enhancing its stability within the air outlet.

[0031] The above is only used to illustrate the technical solution of this utility model and not to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
