Compared with traditional mercury vapor ultraviolet disinfection lamps, LED light sources have the advantages of more energy saving, long life, mercury-free and environmental protection. The wavelength of ultraviolet light emitted by this type of disinfection lamp is mainly concentrated in the range that can effectively sterilize and disinfect, usually in the UVC band, especially between 200 and 300 nanometers, especially around 254 nanometers, because ultraviolet light in this band has a strong destructive effect on the DNA or RNA of microorganisms (such as bacteria, viruses, spores), thereby inhibiting their replication and growth to achieve the purpose of disinfection.

[0037] The housing 31 can be detachably fixed on the ceiling or the ground, the housing 31 is fixed with the first motor 32, the output shaft of the first motor 32 is fixed to one end of a first crank 33, the other end of the first crank 33 is rotatably connected to a first slider 34, the first slider 34 is disposed in a first guide groove 35 and moves along the first guide groove 35, the first guide groove 35 is provided on a first connecting rod 36, and one end of the first connecting rod 36 away from the first guide groove 35 is rotatably connected to the housing 31;

[0038] The LED light strip 1 and the fan 2 are mounted on the first connecting rod 36 .

[0039] Among them, those skilled in the art can design the shape of the shell 31 according to actual needs. In order to facilitate the display of the internal structure, the shell 31 is set as a plate in this embodiment.

[0040] In the utility model, the first motor 32 rotates to drive the first crank 33 to rotate, the first crank 33 drives the first slider 34 to rotate, the first slider 34 reciprocates in the first guide groove 35 and drives the first connecting rod 36 to swing back and forth, the first connecting rod 36 drives the LED light strip 1 and the fan 2 to swing back and forth, thereby expanding the illumination range of the LED light strip 1.

[0041] Among them, the structure of the first crank 33 can be set as a telescopic rod, and specific reference can be made to the structure of the telescopic rod of a telescopic umbrella, so that the length of the first crank 33 can be changed, and then the swing range of the first connecting rod 36 can be changed, thereby further expanding the illumination range of the LED light strip 1 and the swing range of the fan 2.

[0042] As a further explanation of the present invention, one end of the first connecting rod 36 away from the first guide groove 35 is rotatably connected to the housing 31, and its specific connection structure is as follows:

[0043] One end of the first connecting rod 36 away from the first guide groove 35 is hingedly connected to the housing 31 .

[0044] For further explanation of the present invention, see Figure 3 and Figure 5 , one end of the first connecting rod 36 away from the first guide groove 35 is rotatably connected to the housing 31, and its specific connection structure is:

[0045] A second guide groove 361 is provided at one end of the first connecting rod 36 away from the first guide groove 35, and a second slider 362 is arranged in the second guide groove 361 and moves along the second guide groove. The second slider 362 is bearing-connected to a nut 363, and the nut 363 is threadedly connected to a lead screw 364. The nut 363 is arranged in a first guide rail 365 and moves along the first guide rail 365. The first guide rail 365 is fixed to the housing 31, and the first guide rail 365 is bearing-connected to the lead screw 364.

[0046] The lead screw 364 may pass through the first guide rail 365 and then be installed with a handle to facilitate the rotation of the lead screw 364 . The first guide rail 365 and the nut 363 are configured in a dovetail shape.

[0047] Among them, in the utility model, when the screw 364 is rotated, the nut 363 can drive the second slider 362 to move in the second guide groove 361. Since the second slider 362 and the nut 363 are connected by bearings, the swing amplitude of the first connecting rod 36 can be adjusted through the above structure. Therefore, it is possible to adjust the position of the nut 363 in a large space to increase the swing range of the first connecting rod 36. On the contrary, in a small space, the swing range of the first connecting rod 36 can be reduced.

[0048] For further explanation of the present invention, see Figure 6 , the other end of the first crank 33 is rotatably connected to the first slider 34, and its specific structure is as follows:

[0049] The other end of the first crank 33 is connected to the first shaft 331 through a bearing, and the first shaft 331 is connected to the first slider 34 through a bearing.

[0051] In the utility model, the output shaft of the first motor 32 rotates through the pulley mechanism to rotate the first shaft 331, and the rotation of the first shaft 331 drives the second crank 335 to rotate, and the second crank 335 drives the second motor 336 and the fan 2 to rotate together. Therefore, when the fan 2 can follow the reciprocating swing of the first connecting rod 36, it can also be driven by the first shaft 331 to rotate axially, and can also be driven by the second motor 336 to rotate. Therefore, the range of the fan 2 can be further improved, thereby increasing the airflow in the space, reducing the existence of dead corners, and thus improving the disinfection effect.

[0052] Among them, the first shaft 331, the second crank 335, the second motor 336 and the fan 2 are symmetrically arranged in two groups along the midpoint of the length direction of the first connecting rod 36. The symmetrically arranged first shaft 331 can be driven by a rotating motor, or the two first shafts 331 are driven and connected by a tensioning wheel mechanism.

[0053] For further explanation of the present invention, see Figure 6 , the second crank 335 includes a first section 3351 and a second section 3352;

[0054] One end of the first section 3351 is fixed to the first shaft 331 , the other end of the first section 3351 is tilted and fixed to the second section 3352 , and the second section 3352 is fixed to the second motor 336 .

[0057] As a further explanation of the present invention, the second slider 362 is a dovetail slider, and the second guide groove 361 is a dovetail guide groove matching the shape of the second slider 362 .

[0058] By providing the above-mentioned dovetail structure, when the housing 31 is fixed on the ceiling, the first connecting rod 36 will not fall off, thereby avoiding failure of the structural connection.

[0059] As a further explanation of the present invention, the LED light strip 1 is respectively fixed on the side surface of the first connecting rod 36 and the surface away from the first motor 32 .

[0060] As a further explanation of the present invention, wind guide vanes are respectively fixed to both ends of the first connecting rod 36, and the wind guide vanes are used to promote air flow.

[0061] The air guide blade is a prior art, and the utility model does not need to draw a specific structure. Those skilled in the art can install it at any position on the first connecting rod 36 according to actual needs.

[0062] As a further explanation of the present invention, the length of the second guide groove 361 is equal to the length of the first guide rail 365 .
