Ultraviolet rays with two wavelengths are mainly adopted in the market, wherein one wavelength is 253.7 nm; the other is 185nm wavelength, both of which are ultraviolet rays invisible to the naked eye. Wherein 185nm ultraviolet rays can convert oxygen in air into ozone for sterilization, and 253.7nm ultraviolet rays are directly sterilized by direct irradiation. Therefore, 253.7nm ultraviolet rays cannot be completely sterilized in places where the ultraviolet rays cannot irradiate, and ozone generated by 185nm ultraviolet rays can make up for the defect that the ultraviolet rays cannot be directly irradiated to kill bacteria at dead angles, but the ozone can harm human health and needs ventilation after use.

The utility model discloses a height-adjustable ultraviolet disinfection lamp, which comprises a base, wherein internal threads are fixedly arranged at the inner part of the upper end of the base, an electric telescopic rod is connected with the upper end of the base in a threaded manner, a supporting plate is fixedly arranged at the upper end of the electric telescopic rod, a placing box is fixedly arranged at the upper end of the supporting plate, first sliding grooves are fixedly arranged on two sides of the inner wall of the placing box, sliding plates are slidably arranged on two sides, far away from the inner wall of the placing box, of the first sliding grooves, second sliding grooves are fixedly arranged on two sides, far away from the first sliding grooves, of the sliding plates, an ultraviolet disinfection lamp is slidably arranged between the two second sliding grooves, and a battery box is fixedly arranged on one side of the placing box.

The above prior art solutions have the following drawbacks: although the function of adjusting the position of the ultraviolet luminous point is realized through a mechanical structure so as to adapt to different use scenes, the characteristics of two ultraviolet rays can not be considered due to the fact that only ultraviolet rays with a single wave band are radiated, when ultraviolet rays with the wave band of 253.7nm are used, the sterilizing and disinfecting effects of corners are not satisfactory, and when ultraviolet rays with the wave band of 185nm are used, generated ozone remains in a field to cause harm to personnel, so that the application range is still narrow.

For more convenient assembly, be equipped with the circular through-hole that is used for fixed ultraviolet lamp body on the lamp stand top surface, be equipped with round recess on the lamp stand lateral wall, be equipped with round foam in the recess. The structure is characterized in that foam is used for realizing interference fit between the metal protective cover and the lamp holder.

In order to protect the ultraviolet lamp body and not weaken the disinfection effect, the metal protection cover is cylindrical, four rectangular light-transmitting windows are formed in the side wall of the metal protection cover, and hooks are arranged on the top surface of the metal protection cover. The metal protection cover can effectively protect the rotary cover and the ultraviolet lamp body and can also prevent scalding caused by direct contact with the ultraviolet lamp body.

In order to be more convenient to use, a battery is arranged inside the base. The structure is characterized in that the structure can supply power for USB and battery, and various power supply modes can enable the disinfection lamp to be powered by the battery when the USB is inconvenient to supply power.

Compared with the prior art, the ultraviolet lamp tube with the wavelength of 253.7nm and low ozone can be used indoors, the ultraviolet lamp tube with the wavelength of 185nm and high ozone can be used in closed spaces such as a wardrobe and a cabinet by matching with a hook, and the ultraviolet lamp tube can release ozone while surface sterilization is achieved, so that dead corners of a small space are killed. On the other hand, the user can choose to assemble the rotating cover according to the use requirement, so that the light path is controlled, and the killing effect on a certain direction is enhanced.
