In order to improve the bactericidal effect, in this embodiment, the number of the ultraviolet generators 81 is multiple, and the plurality of ultraviolet generators 81 are arranged at intervals along the extending direction of the air outlet 10c. Since an ultraviolet generator 81 is arranged at a certain distance in the extending direction of the air outlet 10c, it can be ensured that every position in the circumferential direction of the casing 10 is irradiated by ultraviolet light, avoiding the generation of dark areas, so that the ultraviolet rays from the air outlet 10c The air discharged from each position is sterilized by ultraviolet light to improve the sterilization effect. Please refer to the figure, specifically, the ultraviolet generator 81 includes a substrate 811 and an ultraviolet lamp bead 812 disposed on the substrate 811 . Usually, a plurality of ultraviolet lamp beads 812 can be arranged on one substrate 811 . Of course, in other embodiments, the number of ultraviolet generators 81 can also be one, that is, the substrate 811 is arranged in a ring along the extension direction of the air outlet 10c, and is arranged around the periphery of the fan 20, on the substrate 811 and along its ring A plurality of ultraviolet lamp beads 812 are arranged at intervals. In order to better fix the substrate 811 , in this embodiment, the substrate 811 is fixed to the housing 10 , for example, the substrate 811 and the housing 10 are fixed by screws, or the substrate 811 and the housing 10 are fixed by welding or bonding. In addition, a support boss may also be provided on the inner wall of the housing 10, and the substrate 811 rests on the support boss.

Further, the sterilizing device further includes a photocatalyst module arranged in the air duct 10a, and the photocatalyst module is opposite to the ultraviolet generator 81 and arranged at intervals.

Because a plurality of wind holes 82a are set on the photocatalyst base material 82, the photocatalyst is coated in the wind hole 82a, thereby increasing the smear area of the photocatalyst, so better catalytic effect can be produced under the action of ultraviolet rays, and the air and photocatalyst can be improved. the contact area. At the same time, the setting of the air passage hole 82a can also reduce the obstruction of the photocatalyst substrate 82 to the air. Since the ultraviolet generator 81 is located below the photocatalyst module, compared with the way that the ultraviolet generator 81 and the photocatalyst module are spaced left and right, the blocking of the air on the outlet side of the blower fan 20 can be reduced. Preferably, the interval between the photocatalyst substrate 82 and the substrate 811 of the ultraviolet generator 81 is less than or equal to 20mm, such as 20mm, 15mm or 10mm, etc., when the distance between the photocatalyst substrate 82 and the substrate 811 of the ultraviolet generator 81 When the interval is less than or equal to 20mm, the radiation area of the ultraviolet light bead 812 of the ultraviolet light generator 81 is the largest at this time, and at the same time, the maximum range of the ultraviolet light bead 812 is guaranteed to irradiate the photocatalyst module. decompose, and eventually form small molecular substances that are harmless to the human body.

In this embodiment, the side edges of the two opposite ends of the photocatalyst substrate 82 are covered with installation shells 83, and the two installation shells 83 are connected by an installation plate 84, and the installation plate 84 is connected to the housing 10. fixed. Specifically, when the photocatalyst base material 82 is arranged horizontally, and the air passage hole 82a penetrates along the up and down direction, the installation shell 83 is arranged on the two opposite ends of the photocatalyst base material 82 along the horizontal direction, and wraps the end of the photocatalyst base material 82 to set , that is, each installation shell 83 is arranged in a U-shape, and is clamped at the end of the photocatalyst substrate 82 . The bottom surfaces of the two mounting shells 83 are provided with a mounting plate 84 to connect the two mounting shells 83 together, and the mounting plate 84 is fixed with the shell 10, for example, by screws or by welding, so that The photocatalyst substrate 82 is fixed on the casing 10 . In addition, slots may be provided on the inner wall of the housing 10 , and the mounting plate 84 is tightly fitted into the slots to be fixed. In this embodiment, the mounting plate 84 protrudes laterally from the photocatalyst substrate 82 so as to be fixed with the housing 10 .

The casing 10 includes an upper casing and a lower casing connected to each other, the air outlet 10c is arranged on the upper casing, the air inlet 10b is arranged on the lower casing, and a communication port is provided at the bottom of the upper casing to communicate with the upper casing. The lower shell is connected, the fan 20 and the ultraviolet generator 81 are arranged on the upper shell, the first filter element 51 is arranged on the lower shell, and the first filter element 51 is cylindrical And it is arranged around the edge of the communicating port, and the air inlet 10b is arranged on the periphery of the first filter element 51 . In this embodiment, it is equivalent to that the air inlet 10b is arranged at the lower part of the housing 10 and is arranged in a ring shape extending along the circumferential direction of the housing 10, and the air inlet 10b is arranged in a grid shape. And in this embodiment, the fan 20 is a centrifugal fan 20 , the axial direction of which is along the vertical direction, and the air outlet 10 c is arranged around the circumference of the fan 20 . In this embodiment, the first filter element is located on the air inlet side of the fan 20, which can filter the air flowing in from the air inlet 10b, filter out the oily fume in the air, and prevent the oily fume from adhering to the blades of the fan 20 and making it difficult to clean. The ultraviolet generator 81 is positioned at the air outlet side of the fan 20, which can ensure that the air flowing out from the air outlet 10c has been sterilized by the ultraviolet generator 81, so the air flowing to the room is cleaner. In addition, in other embodiments, the smoke machine can also be arranged horizontally, so that the wind enters and exits along the left and right directions.
