[0049] The air supply device 12 is connected to the inlet 7 of the air inlet part 2, and supplies air to the deodorizing device from the axial direction of the inlet 7.

The joint 13 can be any form to achieve fixed connection. In this embodiment, the axial direction of the inlet 7 is parallel to the ceiling, and the airflow is sent out from the outlet 8 after passing through the photocatalyst generating device 5. The axial direction of the outlet 8 is perpendicular to the axial direction of the inlet 7, so that the airflow can fully drive the photocatalyst generated by the photocatalyst generating device 5 to the outside.

[0050] The working principle of the ventilation device in this embodiment is as follows:

[0051] After the ventilation device is turned on, the air supply device 12 starts to work and delivers airflow to the inlet 7. The light source 17 emits ultraviolet light to irradiate the photocatalyst generating device 5, and the photocatalyst generating device 5 generates a photocatalytic reaction and then generates strong oxidizing substances. The airflow generated by the fan drives the generated strong oxidizing substances, so that the strong oxidizing substances can flow to the outside with it to achieve the purpose of deodorization.

[0052] In addition, the purpose of providing the base 1 in this embodiment is to modularize the deodorizing device. The base 1 may be omitted, and the light source 17 and the photocatalyst generating device 5 may be directly installed on the base of the ventilation device.

[0053] In this embodiment, a photocatalyst generating device 5 is used for deodorization. The photocatalyst can produce strong oxidizing substances under light irradiation, which can be used to decompose organic compounds, bacteria and viruses. In addition, in the technical solution, at least a part of the two connecting parts 6 is constructed so that the distance between the inlet 7 of the air inlet part 2 is smaller than the distance between the outlet 8 of the air outlet part 3. The photocatalyst generating device 5 is installed at an angle with the axis of the air outlet part 3. In this posture, when the ultraviolet light is irradiated on the photocatalyst generating device 5, it can be irradiated at an angle not parallel to the air outlet part 3, so that the ultraviolet light will not be emitted through the outlet 8 of the air outlet part 3, thereby avoiding the light source 17 used to irradiate the photocatalyst from irradiating the user. A generating area multiplication portion 9 is provided between the two connecting parts 6, which can increase the area of ​​the photocatalyst receiving irradiation from the light source 17 and improve the photocatalytic effect. The generating area multiplication part 9 has a crest 10 and a trough 11, and a trough 11 is formed between adjacent crests 10. The crests 10 and the troughs 11 extend along the first direction 14 and are arranged along the second direction 15, which increases the area of ​​the photocatalyst receiving the irradiation of the light source 17 and improves the photocatalytic effect. The air inlet is connected to the air supply device 12, and the air supply device 12 supplies air to the deodorizing device from the axial direction of the inlet 7, and can use the airflow to drive the strong oxidizing substances generated by photocatalysis. The combination part 13 is configured to guide the air supply device 12 to be combined with the deodorizing device from the axial direction of the inlet 7, so as to facilitate the connection of the air supply device 12. The air supply device 12 and the deodorizing device are arranged on the axis of the inlet 7 so that the air supply device 12 supplies air to the deodorizing device. The light source 17 is configured to irradiate the photocatalyst generating device 5 in a direction intersecting with the outlet 8 to prevent the light source 17 from irradiating outside the outlet 8. At least a part of the two connecting parts 6 is supported on the part of the air duct 4 extending along the axial direction of the inlet 7 to support the photocatalyst generating device 5. The generation area of ​​the photocatalyst generator 5 does not intersect with the projection of the outlet 8 on the plane perpendicular to the axial direction of the outlet 8 , thereby preventing the user from seeing the photocatalyst generator 5 from the outlet 8 .
