An A switch 4, a C switch 5 and an L switch 6 are arranged on the outside of the equipment body 1. The A switch 4, the C switch 5 and the L switch 6 are all existing push-type switches. A hollow baffle 9 is arranged on one side of the equipment body 1. The baffle 9 is a hollow columnar tube. The baffle 9 is fixedly connected to the equipment body 1. A plurality of rows of through holes 10 are opened on the surface of the baffle 9. A UVA ultraviolet disinfection lamp 12, a UVC germicidal lamp 13 and an LED lamp 14 are arranged inside the baffle 9. The UVA ultraviolet disinfection lamp 12, the UVC germicidal lamp 13 and the LED lamp 14 are all fixed inside the equipment body 1 through a lamp holder. The UVA ultraviolet disinfection lamp 12, the UVC germicidal lamp 13 and the LED lamp 14 are fixed inside the equipment body 1 through a lamp holder. The toxic lamp 12 disinfects the areas that cannot be irradiated, the UVC germicidal lamp 13 sterilizes the irradiated area, the LED lamp 14 is an LED lamp for lighting, a fan 11 is provided between the baffle 9 and the device body 1, the fan 11 is fixedly connected to the device body 1, and the fan 11 has the effect of blowing air and dissipating heat, the outer side of the baffle 9 is provided with a pen-type housing 7, the pen-type housing 7 is fixedly connected to the baffle 9, and the inner wall of the pen-type housing 7 is located at the top of the through hole 10. A convex lens 15 connected to the baffle 9 is provided on the side of the LED lamp 14 away from the fan 11. The convex lens 15 serves the purpose of focusing light, and an adjustment mechanism 16 is provided between the convex lens 15 and the device body 1.

[0022] This program has the following working process:

[0023] When the user uses the device, when lighting is needed, directly press the L switch 6, the L switch 6 turns on the LED lamp 14 to play a lighting role. When encountering an area that needs to be disinfected, directly press the A switch 4, the A switch 4 turns on the UVA ultraviolet disinfection lamp 12 to disinfect the irradiated area. When the area needs to be sterilized, directly press the C switch 5, the C switch 5 turns on the UVC sterilization lamp 13, the UVC sterilization lamp 13 sterilizes the area. When the device is in use, the fan 11 starts to rotate, and the fan 11 brings out the hot air flow inside the device. The hot air flow is discharged through the through hole 10 of the baffle 9 to dissipate heat inside the device.

[0024] According to the above working process, we can know that:

[0025] When lighting is needed, directly press the L switch 6, the L switch 6 turns on the LED lamp 14, which plays a role of lighting. When encountering an area that needs to be disinfected, directly press the A switch 4, the A switch 4 turns on the UVA ultraviolet disinfection lamp 12 to disinfect the irradiated area. When the area needs to be sterilized, directly press the C switch 5, the C switch 5 turns on the UVC germicidal lamp 13, and the UVC germicidal lamp 13 sterilizes the area. When the equipment is in use, the fan 11 starts to rotate, and the fan 11 brings out the hot air flow inside the equipment. The hot air flow is discharged through the through hole 10 of the baffle 9 to dissipate the heat inside the equipment. Compared with the prior art, the flashlight plays the role of lighting, the UVC ultraviolet disinfection lamp simply disinfects the irradiated area, and the UVA The germicidal lamp sterilizes the parts that cannot be irradiated, and a single lamp has a single effect. However, the user needs to carry multiple lamps when using them. Different lamps need to be used for different states, which takes time to replace. The operation is inconvenient and inconvenient to use. Moreover, when the lamp is in use, the lamp will generate a higher temperature, and the service life of the lamp is short. The focal length of the light is mostly not adjustable, which is inconvenient to use. This solution combines the three lamps into a pen-type lamp. When dealing with different states, different switches are pressed. The functions are diverse and convenient for the operator to use. Moreover, a fan 11 is provided inside the lamp to facilitate the heat dissipation of the internal lamp. The focal length of the convex lens 15 of the lamp is adjusted by the adjustment mechanism 16, which is more convenient to use the lamp.

[0026] Furthermore, the height of the ventilation groove 8 gradually decreases from the middle of the baffle 9 to the two ends, and the shortest height of the ventilation groove 8 is greater than 1 mm. When the fan 11 dissipates heat from the inside of the device body 1, hot air is discharged from the inside of the ventilation groove 8. The ventilation groove 8 is tapered to prevent external humid air and tissue fluid from entering the inside of the device, thereby protecting the device while facilitating the heat dissipation of the device.

[0027] Furthermore, two symmetrically distributed waterproof blocks 24 are provided on one side of the interior of the ventilation groove 8, wherein one waterproof block 24 is fixedly connected to the top of the inner wall of the ventilation groove 8, and the other waterproof block 24 is fixedly connected to the surface of the baffle 9. When the equipment is in use, when external water vapor enters from the notch of the ventilation groove 8, the two staggered waterproof blocks 24 can reduce the entry of humid air from the external environment, thereby better protecting the equipment.

[0028] Furthermore, a latch 3 is provided at the end of the connecting frame 2 close to the device body 1. The end of the latch 3 is relatively sharp. When the device is not in use, the user inserts it into a pocket. The latch 3 at the end of the connecting frame 2 makes it easier to position the device and thus makes it easier to carry the device.

[0029] Furthermore, the adjusting mechanism 16 includes a mounting seat 18 fixedly connected to the convex lens 15, one end of the mounting seat 18 is inserted into the baffle 9, and a sliding rod 17 with one end inserted into the inside of the device body 1 and the baffle 9 is provided on one side of the mounting seat 18, and a push block 20 is fixedly connected to the end of the sliding rod 17, and a rotating rod 22 is rotatably connected to the outer side of the pushing block 20, and a torsion spring shaft 21 is provided between the rotating rod 22 and the pushing block 20. A plurality of teeth 23 with one end inserted into the end of the rotating rod 22 are provided on the surface of the device body 1. When the user uses the device to disinfect and sterilize the ground, the pushing block 20 is directly pushed, the rotating rod 22 rotates, the torsion spring shaft 21 rotates, the rotating rod 22 moves on the teeth 23, the pushing block 20 drives the sliding rod 17 to move, and the sliding rod 17 drives the convex lens 15 to move, and the convex lens 15 controls the convergence point of the light. After moving to the appropriate position, the pushing block 20 is released, and the rotating rod 22 bracket is clamped in the clamping tooth 3, and the light can adjust its convergence intensity, thereby making it more convenient for the user to fully disinfect the ground position.

[0030] Furthermore, when the slide bar 17 contacts the mounting seat 18, a spring 19 is provided on the side of the mounting seat 18 away from the slide bar 17, and the two ends of the spring 19 are respectively fixedly connected to the mounting seat 18 and the baffle 9. When the slide bar 17 is not fixedly connected to the mounting seat 18, the spring 19 is ejected to facilitate the resetting of the convex lens 15 and the separation of the slide bar 17 and the mounting seat 18, thereby making it more convenient to separate the equipment adjustment mechanism 16 from the baffle 9, thereby facilitating the assembly of the equipment.
