Description

Technical Field

[0001] The utility model provides an ultraviolet sterilization lamp which can be automatically lifted and lowered, and relates to the field of ultraviolet lamps. Background Art

[0002] Ultraviolet lamps, also called ultraviolet disinfection lamps, use ultraviolet rays emitted by mercury lamps to achieve sterilization and disinfection functions. Ultraviolet disinfection technology has an incomparable sterilization efficiency that other technologies cannot match, with a sterilization efficiency of 99% to 99.9%. The scientific principle of ultraviolet disinfection: it mainly acts on the DNA of microorganisms, destroys the DNA structure, and makes them lose the ability to reproduce and self-replicate, thereby achieving the purpose of sterilization and disinfection. Ultraviolet disinfection has the advantages of being colorless, odorless, and free of chemical residues.

[0003] Most of the existing ultraviolet germicidal lamps in medical institutions are traditionally installed on the ceiling. The lamp tubes are high above the ground, which has a poor sterilization effect on the ground and is inconvenient for daily maintenance. For example, when wiping or replacing the lamp tubes, personnel need to use ladders to complete the work. The lamp tubes installed on the ceiling are exposed under the ceiling, and there is a risk of breaking and injuring people when moving large items in the room. To this end, we propose an ultraviolet germicidal lamp that can be automatically raised and lowered. Utility Model Content

[0004] In order to solve the above problems, the utility model provides an ultraviolet germicidal lamp that can be automatically raised and lowered, which can be automatically raised and lowered, thereby improving the sterilization effect on the ground and subsequent maintenance work.

[0005] The utility model provides an ultraviolet germicidal lamp which can be automatically lifted and lowered, comprising an ultraviolet germicidal lamp body and a lifting assembly for driving the ultraviolet germicidal lamp body to be lifted and lowered, the lifting assembly comprising a body, a stepper motor fixedly connected to the body, a winch fixedly connected coaxially with an output shaft of the stepper motor, and a cable wound on the winch, two cables are symmetrically arranged, a first roller and a second roller for guiding are symmetrically arranged on the body, an end of the cable away from the winch passes around the first roller and the second roller and is fixedly connected to the ultraviolet germicidal lamp body.

[0006] Preferably, a control mainboard is also provided on the fuselage, and the control mainboard is electrically connected to the stepper motor.

[0007] Preferably, one end of the cable is fixedly connected to the winch, and the two cables are respectively fixedly connected to two sides of the winch.

[0008] Preferably, mounting side ears for installation are provided on both sides of the fuselage, and mounting holes are opened on the mounting side ears.

[0009] Beneficial effects of the utility model:

[0010] The utility model provides an ultraviolet germicidal lamp which can be automatically lifted and lowered. By setting a lifting component, the ultraviolet germicidal lamp body can be controlled to be lifted and lowered. By lowering the height of the ultraviolet germicidal lamp body, a good sterilization and disinfection effect can be achieved on the ground. At the same time, by lowering the height of the ultraviolet germicidal lamp body, maintenance and daily cleaning of the ultraviolet germicidal lamp body are convenient. When the ultraviolet germicidal lamp body is not in use, it can be raised to the highest point by the lifting component, thereby not affecting normal activities of people in the room.

[0012] (1. UV germicidal lamp body; 2. Cable; 3. Body; 4. Roller 1; 5. Roller 2; 6. Winch; 7. Stepper motor; 8. Control main board) DETAILED DESCRIPTION

[0013] The preferred embodiments of the present utility model will be described in detail below in conjunction with the accompanying drawings.

[0014] Reference Figure 1 The utility model provides an ultraviolet germicidal lamp that can be automatically lifted and lowered, including an ultraviolet germicidal lamp body 1 and a lifting assembly for driving the ultraviolet germicidal lamp body 1 to lift and lower. The lifting assembly includes a fuselage 3, a stepper motor 7 fixedly connected to the fuselage 3, a winch 6 coaxially fixedly connected to the output shaft of the stepper motor 7, and a cable 2 wound on the winch 6. The cables 2 are symmetrically arranged with two cables. The fuselage 3 is symmetrically provided with rollers 1 4 and 2 5 for guiding. One end of the cable 2 is fixedly connected to the winch 6, and the other end passes through the rollers 1 4 and 2 5 and is fixedly connected to the ultraviolet germicidal lamp body 1. Specifically, the winch 6 can be driven to rotate by the stepper motor 7, and the winch 6 drives the cable 2 to reel or unreel, thereby driving the ultraviolet germicidal lamp body 1 to lift and lower. When sterilization is required, the height of the ultraviolet germicidal lamp can be lowered, so as to sterilize and disinfect the ground well. After use, the ultraviolet germicidal lamp body 1 can be raised again, which will not affect the normal activities of personnel.

[0015] Furthermore, the body 3 of the present invention is also provided with a control mainboard 8, which is electrically connected to the stepper motor 7. Specifically, the control mainboard 8 is used to control the opening and closing and forward and reverse rotation of the stepper motor 7, thereby controlling the lifting and lowering of the ultraviolet germicidal lamp body 1.

[0016] Furthermore, the fuselage 3 in the utility model is provided with mounting side ears for installation on both sides, and the mounting side ears are provided with mounting holes. Specifically, the fuselage 3 can be fixed to the ceiling by bolts through the mounting side ears and the mounting holes.

[0017] Working principle: When the utility model is in use, when the ultraviolet germicidal lamp body 1 needs to be used for disinfection and sterilization, the stepper motor 7 can be started to drive the winch 6 to rotate, and the winch 6 drives the cable 2 to unwind, thereby driving the ultraviolet germicidal lamp body 1 to lower its height, which can disinfect and sterilize the ground well. The ultraviolet germicidal lamp body 1 with the height lowered is also convenient for maintenance and cleaning. After use, the stepper motor 7 is started again to reverse it, driving the ultraviolet germicidal lamp body 1 to rise to the ceiling, thereby not affecting the normal activities of personnel.

[0018] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
