Fig. 4 is a schematic structural view of the sterilization module 300 provided in this embodiment at a first viewing angle, and fig. 5 is a schematic structural view of the sterilization module 300 provided in this embodiment at a second viewing angle. Referring to fig. 1 to fig. 3 in combination with fig. 4 and fig. 5, in the present embodiment, the sterilization module 300 includes a bracket 310 and an ultraviolet lamp 320 fixed on the bracket 310, wherein the bracket 310 is detachably connected to the air outlet duct 412.

Through setting up the support 310 of sterilization module 300 to be connected with the air outlet 412 of spiral case 410 can be dismantled, when ultraviolet lamp 320 broke down, can pull down support 310 from air outlet 412 to maintain operation to ultraviolet lamp 320 in open area, or, when ultraviolet lamp 320 broke down and can't continue to use, can pull down sterilization module 300 from air outlet 412, and install new sterilization module 300 in air outlet 412.

So set up, on the one hand, be convenient for maintain the operation to the module 300 that disinfects, on the other hand, this kind of modularization and can dismantle the mode of connection, can also be when the module 300 that disinfects takes place to damage, the module 300 that disinfects that directly changes the new, and need not to change new trend device whole, greatly reduced maintain and after sale cost.

Referring to fig. 4 and fig. 5, in the present embodiment, the bracket 310 may include a mounting plate 311 and two mounting lugs 312, wherein the two mounting lugs 312 are respectively and vertically connected to two ends of the mounting plate 311, the two mounting lugs 312 are oppositely disposed, the ultraviolet lamp 320 is fixedly disposed on the mounting plate 311, and the two mounting lugs 312 are respectively and detachably connected to two sidewalls of the air outlet duct 412.

The arrangement form of the bracket 310 is simple in structure, and not only can the ultraviolet lamp 320 be fixedly installed by using the installation plate 311, but also the two installation lugs 312 can be detachably connected with the air outlet duct 412.

Specifically, referring to fig. 4 and fig. 5, the mounting plate 311 is in a strip shape, two mounting lugs 312 are respectively and fixedly disposed at two ends of the mounting plate 311 in the length direction, and each mounting lug 312 is respectively located at the middle position of the mounting plate 311 in the width direction.

Preferably, the number of the ultraviolet lamps 320 is two, and the two ultraviolet lamps 320 are arranged at intervals along the length direction of the mounting plate 311. So set up, can further increase the coverage area that ultraviolet lamp 320 jetted out the light to improve the sufficiency of disinfecting to the new trend.

In another embodiment, the mounting lugs 312 may be formed by bending both ends of the mounting plate 311 in the longitudinal direction in the same direction.

Specifically, in the present embodiment, the inner surfaces of the two side walls of the air outlet duct 412 are respectively and fixedly provided with the positioning columns 413, the two mounting ears 312 are respectively provided with the positioning holes 313, and the two positioning holes 313 can be correspondingly sleeved on the two positioning columns 413 one to one.

When the sterilization module 300 needs to be installed in the air outlet duct 412, the bracket 310 can be held by hand to reduce the distance between the two installation lugs 312, so that the two installation lugs 312 are located between the two positioning posts 413, and meanwhile, the position of the bracket 310 is adjusted to enable the positioning holes 313 on the installation lugs 312 to be opposite to the positioning posts 413 on the air outlet duct 412; then, the bracket 310 is released, so that the positioning holes 313 on the two mounting lugs 312 are respectively sleeved on the two positioning columns 413 of the air outlet duct 412 under the action of the elastic restoring force of the bracket 310, thereby realizing the mounting of the sterilization module 300.

Similarly, when the sterilization module 300 needs to be detached from the air outlet duct 412, the bracket 310 can be held by hand to reduce the distance between the two mounting lugs 312, so that the positioning holes 313 on the two mounting lugs 312 are separated from the two positioning posts 413 on the air outlet duct 412, and then the bracket 310 is moved out from between the two positioning posts 413, thereby achieving the detachment of the sterilization module 300.
