Description

Multi-band UV disinfection lamp

technical field

The utility model relates to the field of ultraviolet disinfection lamps, in particular to a multi-band ultraviolet disinfection lamp.

Background technique

Two wavelengths of ultraviolet rays are mostly used in the market, one is 253.7nm wavelength; the other is 185nm wavelength, both of which are invisible to the naked eye. Among them, 185nm ultraviolet rays can convert oxygen in the air into ozone for sterilization, while 253.7nm ultraviolet rays can directly sterilize through direct irradiation. Therefore, 253.7nm ultraviolet rays cannot completely sterilize in places where there is no sunlight, and the ozone generated by 185nm ultraviolet rays can make up for the defects that ultraviolet rays cannot be directly irradiated, and kill bacteria in dead corners, but ozone will endanger human health, and ventilation is required after use.

The existing Chinese utility model with the application number CN202122507596.2 discloses a height-adjustable ultraviolet disinfection lamp, including a base, the upper end of the base is fixedly provided with internal threads, and the upper end of the base is threadedly connected to an electric lamp. A telescopic rod, the upper end of the electric telescopic rod is fixedly provided with a support plate, and the upper end of the support plate is fixedly provided with a storage box, and both sides of the inner wall of the storage box are fixedly provided with a first chute, and the two first chute The side far away from the inner wall of the storage box is slidably provided with a sliding plate, and the sides of the two sliding plates away from the first chute are both fixedly provided with a second chute, and between the two said second chute is slidably provided with a sliding plate. An ultraviolet sterilizing lamp, a battery box is fixedly arranged on one side of the storage box.

The above-mentioned existing technical solutions have the following defects: although the function of adjusting the position of the ultraviolet luminous point is realized through the mechanical structure to adapt to different usage scenarios, it is still unable to take into account the characteristics of the two ultraviolet rays because it only radiates ultraviolet rays of a single band. When using ultraviolet rays in the 253.7nm band, the sterilization effect in the corners is not satisfactory. When using ultraviolet rays in the 185nm band, the ozone generated will remain in the venue and cause harm to personnel, so the scope of application is still narrow.

Contents of the invention

The technical problem to be solved by the utility model is to aim at the deficiencies of the prior art, and propose a multi-band ultraviolet disinfection lamp with two wavelengths at the same time, complete sterilization and wide application.

In order to achieve the above purpose, the multi-band ultraviolet disinfection lamp designed by the utility model includes a metal protective cover, and a lamp holder is arranged inside the metal protective cover, and an ultraviolet lamp body is fixed on the lamp holder, and the outermost part of the ultraviolet lamp body The first layer is a transparent glass cover. Two ultraviolet lamps are arranged inside the transparent glass cover. The two ultraviolet lamps are in the 253.7nm and 185nm bands respectively, and the lower part of the lamp holder is fixed with a base. The characteristic of this structure is that it can provide ultraviolet rays of two wavelengths, and can be used in closets, bathrooms and other hygienic corners, and has a wide range of applications.

In order to improve the disinfection efficiency, a rotating cover slot is provided on the lamp base, and a rotating cover is inserted into the rotating cover slot, and the rotating cover is cylindrical in shape matching with the metal protective cover. The inner wall is a reflective coating, with upper and lower openings, and a light hole is opened on the side wall. The position of the light hole is controlled by the rotation of the rotating cover, thereby controlling the irradiation area of ultraviolet rays, and the reflective coating on the inner wall can further increase the light intensity of the irradiation area.

In order to provide ordinary lighting effects, LED light-emitting holes are evenly distributed on the top surface of the lamp holder, and LED light-emitting sheets are arranged in the LED light-emitting holes, and the LED light-emitting sheets are evenly distributed on the circuit board. The circuit board is circular and located under the lamp holder. When not used as a disinfection lamp, the LED luminescent sheet can be used as an emergency lighting lamp.

For more convenient assembly, a circular through hole for fixing the ultraviolet lamp body is provided on the top surface of the lamp holder, a circle of grooves is provided on the side wall of the lamp holder, and a circle of foam is arranged in the grooves. The characteristic of this structure is that foam is used to realize the interference fit between the metal protective cover and the lamp holder.

In order to protect the ultraviolet lamp body without weakening the disinfection effect, the metal protective cover is cylindrical, and four rectangular light-through windows are opened on its side wall, and a hook is provided on the top surface of the metal protective cover. The metal protective cover can effectively protect the rotating cover and the ultraviolet lamp body and prevent burns caused by direct contact with the ultraviolet lamp body.

For more convenient use, a battery is provided inside the base. The feature of this structure is that it can be powered by both USB and battery, and multiple power supply methods can allow the disinfection lamp to use battery power when it is inconvenient to use USB power supply.

Compared with the prior art, the utility model takes into account two kinds of wavelengths, and has a wide range of application scenarios. The 253.7nm low-ozone ultraviolet lamp can be used indoors with people, and the 185nm high-ozone ultraviolet lamp can be used in wardrobes, cabinets, etc. Used in a confined space, it releases ozone while sterilizing the surface, and kills dead corners in small spaces. On the other hand, users can choose to assemble a rotating cover according to the needs of use, so as to control the optical path and strengthen the disinfecting effect in a certain direction.
