FIG. 1 illustrates an air treatment device 900, and FIGS. 2A, 2B, 3, 4A, 4B, 5 illustrate an air intake assembly of the air treatment device 900, according to one embodiment of the present invention. In the embodiment shown in fig. 1, the air treatment device 900 is part of an air conditioning system of a vehicle, which in turn may be called an air conditioning module in the field of vehicle air conditioning. To achieve the treatment of air, the air treatment device 900 comprises a housing 1, a fan (not shown in the figures) and an air treatment unit 3.

With continued reference to fig. 2A, 2B, 3, 4A, 4B, 5, the housing 1 has a passage 1a, an inlet for the air flow F and an outlet 103 for the air flow F. The passage 1a communicates with an inlet of the air flow F and an outlet 103 of the air flow F, respectively. The inlet for the gas flow F comprises a first inlet 101 and a second inlet 102. The first inlet 101 allows fresh airflow F outside the vehicle cabin to enter the passage 1a of the housing 1, and the second inlet 102 allows airflow F inside the vehicle cabin to enter the passage 1a of the housing 1. The air treatment unit 3 is arranged in the channel 1a and is used to treat an air flow F entering the channel 1a, which treated air flow F exits the housing 1 via the outlet 103 and enters the vehicle cabin. A fan is arranged in the channel 1a, the operation of the fan being such that the channel 1a is able to draw an airflow F from the first inlet 101 and/or the second inlet 102 and to discharge the airflow F from the outlet 103.

In order to form a refrigeration circuit, the vehicle air conditioning system further comprises a compressor (not shown in the drawings), a throttling device (not shown in the drawings) and a heat exchanger (not shown in the drawings) located outside the casing 1. The heat exchanger located outside the housing 1 is normally arranged in the cabin of the vehicle, integrated with the front end module of the vehicle. The compressor may also be arranged in the cabin of the car. The throttling device may be an electronic expansion valve or a thermostatic expansion valve. The throttle device may be mounted on the housing 1 and located outside the housing 1.

The air treatment unit 3 comprises one or more of a heat exchanger, a heater, a humidifier, a filter element. The air processing unit is used for heating, humidifying, dehumidifying, filtering and the like of air flowing through the air processing unit. In an automotive air conditioning system, a compressor, a throttle device, a heat exchanger as an air handling unit 3, and a heat exchanger located outside a casing 1 are connected by piping to form a refrigeration circuit that allows a refrigerant to circulate.

In order to sterilize the inside of the air treatment device 900, for example, the air treatment unit 3 within the housing 1, the air treatment device 900 further includes an ultraviolet lamp 2 disposed within the housing 1 to sterilize the air treatment unit 3 by irradiating the air treatment unit 3 with the ultraviolet lamp 2. Specifically, the ultraviolet lamp 2 may emit ultraviolet rays toward the air treatment unit 3, and the ultraviolet rays may kill bacteria or other microorganisms on the surface of the air treatment unit 3 after being irradiated to the surface of the air treatment unit 3. The wavelength of the ultraviolet light is preferably between 180 nm and 280 nm.

The ultraviolet lamps 2 are disposed to irradiate different regions of the air treatment unit 3 to increase the region of the air treatment unit 3 which can be irradiated by the ultraviolet lamps 2, thereby enabling the sterilization treatment of the air treatment unit 3 by the air treatment device 900 to be more complete and thorough. In an embodiment not shown, the uv lamp 2 can be caused to irradiate different regions of the air treatment unit 3 by changing the size of the emission angle γ or the irradiation angle β at which the uv light is emitted, while maintaining the position of the uv lamp 2 with respect to the housing 1 and the air treatment unit 3.

As shown in fig. 3 and 5, the uv lamp 2 may be arranged to be movable relative to the air treatment unit 3 to illuminate different areas of the air treatment unit 3. More specifically, in an embodiment not shown, the uv lamp 2 may be arranged to slide along the inner wall of the housing 1 to be movable with respect to the air handling unit 3. For example, a slide rail may be provided on the inner wall of the housing 1, and the ultraviolet lamp 2 may be slid on the slide rail.

In a further embodiment, with continued reference to fig. 3, 5 and 6A, the interior of the housing 1 is provided with a damper 4, the damper 4 being rotatably disposed on the housing 1 about an axis 4 a. The damper 4 is reciprocally rotatable between a first position P1 blocking the second inlet 102 and a second position P2 blocking the first inlet 101 by an angle α of between 40 ° and 120 °, preferably between 60 ° and 90 °. The ultraviolet lamp 2 is mounted on the damper 4 so as to rotate about an axis 4a following the damper 4, thereby being movable relative to the air processing unit 3. The exit angle γ or irradiation angle β of the ultraviolet rays remains unchanged in this embodiment.

In the first position P1, the outside of the damper 4 blocks the airflow F from entering the housing 1 as a return from the second inlet 102. In the second position P2, the outside of the damper 4 blocks the airflow F as fresh air from entering the housing 1 from the first inlet 101. The ultraviolet lamp 2 is installed inside the damper 4, facing the air processing unit 3. In the illustrated embodiment, the air treatment unit 3 is a filter cartridge. In an embodiment not shown, the damper 4 may also be arranged for translational movement relative to the housing 1.

As shown in fig. 2B and 3, the ultraviolet light emitted from the ultraviolet lamp 2 forms a conical irradiation space, the cone angle of the irradiation space is the irradiation angle β, and the ultraviolet lamp 2 also has a certain disinfection effect on the air flow F flowing into the conical irradiation space. The sum of twice the exit angle γ and the illumination angle β is 180 °. When the damper 4 is in the first position P1, the ultraviolet lamp 2 illuminates the first zone a1 of the air handling unit 3, and when the damper is in the second position P2, the ultraviolet lamp 2 illuminates the second zone a2 of the air handling unit 3. The first region a1 and the second region a2 overlap in the middle of the air handling unit 3, forming an overlapping region A3. The overlap area a3 is always illuminated by the uv lamp 2 during the rotation of the uv lamp 2 with the damper 4, so that a better disinfection effect is obtained with respect to the edge area of the air treatment unit 3. Since the overlap area a3 is located in the middle of the air handling unit 3, more air flow F can be handled relative to the edge area of the air handling unit 3. This enables the disinfecting effect and the flow rate of the process air flow F to be matched to each other.

As shown in fig. 2A, 6B, 7, 8A, 8B, the air treatment device 900 further includes a cable 5; the cable 5 is electrically connected with the ultraviolet lamp 2; the cable 5 is used to supply power to the uv lamp 2 or to transmit control signals. The damper 4 has a main body 40 and a rotary shaft 41; the main body 40 has a through hole 40a for allowing the cable 5 to pass therethrough; the rotary shaft portion 41 is rotatably supported by the housing 1 about the axis 4 a. The through hole 40a enables the cable 5 to pass through the main body portion 40, thereby enabling the cable 5 to be routed from the inside of the damper 4 to the outside of the damper 4. The rotation shaft portion 41 can be rotatably fitted to the support hole 10 of the housing 1. The cable 5 may be clearance fitted or interference fitted with the through hole (40 a). When the cable 5 is in interference fit with the through hole (40a), the cable 5 can play a sealing role for the through hole (40 a).

With continued reference to fig. 6B, 8A, 8B, the rotating shaft portion 41 has an inner surface 41a and an outer surface 41B; inner surface 41a defines cable channel 410; the outer surface 41b is rotatably supported by the housing 1; the through hole 40a communicates with the cable channel 410; the cable 5 passes through the through hole 40a and the cable passage 410. Such a design makes the routing of the cable 5 relatively simple. In fig. 8B, the center line of the through hole 40a coincides with the axis 4 a. The rotating shaft 41 is cylindrical and vertically connected to the body 40. In an embodiment not shown, the center line of the through hole 40a may not coincide with the axis 4 a.

As shown in fig. 6A, 6B, 8A, 10, 11, the air treatment device 900 further includes an elastomeric seal 6, the elastomeric seal 6 having an inner wall 6A and an outer wall 6B; the inner wall 6a defines a routing hole 60, the routing hole 60 allowing the cable 5 to pass through; the elastic seal 6 is intended to be jammed in the through hole 40a, wherein the outer wall 6b is adapted to abut against the through hole 40a so that the inner wall 6a can hug the cable 5. In a more specific embodiment, the centerline of the routing hole 60 coincides with the axis 4a, so that the portion of the cable 5 that is gripped by the inner wall 6a can coincide with the axis 4 a. The elastic sealing member 6 may be made of rubber, or may be made of sponge, nonwoven fabric, or the like. The elastic seal member 6 is provided slidably on the cable 5 when the elastic seal member 6 is not inserted into the through hole 40a to change the position of the elastic seal member 6 on the cable 5.

As shown in fig. 9A and 9B, the damper 4 may have a flat plate-like structure. The uv lamp 2 may be attached to one side of the main body portion 40 of the damper 4, and the main body portion 40 has a relief groove 40 a. The cable 5 may be embedded in the relief groove 40 a.

Although the present invention has been described with reference to the preferred embodiments, it is not intended to limit the present invention, and those skilled in the art can make modifications and variations without departing from the spirit and scope of the present invention.
