In recent years, various new viruses have been continuously produced, such as the SARS virus in 2002 and the recent "bird flu" virus. These viruses are highly contagious and pose a serious threat to public health. Therefore, disinfection is often performed on the surrounding objects It is necessary.

Literature records, ultraviolet rays can sterilize, but excessive ultraviolet radiation can cause damage to human skin, eyes, and immune system. Ultraviolet rays can damage human skin cells and cause cancer in severe cases. The eyes are very sensitive to ultraviolet rays, and ultraviolet rays can cause damage to the lens, which is one of the pathogenic factors of senile cataracts.

Generally, the ultraviolet light source includes an ultraviolet lamp tube or a light-emitting diode ultraviolet lamp. The ultraviolet light emitted by this type of ultraviolet light source is divergent and random in direction. Therefore, in order to avoid the above-mentioned harm to the user, the general ultraviolet sterilizing device seals the ultraviolet light source in a cavity impermeable to ultraviolet light, and puts the object to be sterilized into the cavity for sterilization. Sterilization device is all more bulky, is unfavorable for carrying.

Today, with the development of mobile technology, people may carry a variety of portable devices, such as mobile phones, personal digital assistants or notebook computers. Various "portable" devices will also cause people a sense of inconvenience. The sterilization device is made into a very small volume, and people are still not willing to carry an ultraviolet sterilization device with them.

【Detailed ways】

Referring to FIG. 1 , FIG. 2 , FIG. 3 and FIG. 4 , the ultraviolet sterilization device 100 of this embodiment includes an ultraviolet light source 10 , an inner cover 11 , an outer cover 12 , a power supply 13 and a switch 14 .

The ultraviolet light source 10 is arranged in the inner cover 11, preferably at the center of the inner cover 11. The ultraviolet light source 10 includes a negative electrode 101 and a positive electrode 102. The ultraviolet light source 10 can be an ultraviolet lamp or a light-emitting diode ultraviolet lamp. The inner cover 11 and the outer cover 12 are cylindrical, preferably cylindrical, and are respectively provided with an inner cover opening 111 and an outer cover opening 121 for passing through the ultraviolet light emitted by the ultraviolet light source 10 . The material of the inner cover 11 and the outer cover 12 needs to shield the ultraviolet light, such as metal, plastic that is not transparent to ultraviolet light, and the like. Preferably, the inner surface of the inner cover 11 is coated with an ultraviolet light reflective film. The outer cover 12 is sheathed on the inner cover 11 , so that the outer cover 12 can rotate relative to the inner cover 11 .

The ultraviolet light source 10, the power supply 13 and the switch 14 form a circuit, and the switch 14 controls the ultraviolet light source 10 to turn on and off.

In order to prevent the outer cover 12 from falling off from the inner cover 11, an upper bearing plate 15 and a lower bearing plate 16 can be respectively installed at both ends of the inner cover 11, and the upper bearing plate 15 and the lower bearing plate 16 can ensure that the outer cover 12 is set on the inner cover 11 , the outer cover does not fall off, it is preferably circular, and its diameter is greater than that of the inner cover 11 . The upper bearing plate 15, the lower bearing plate 16 and the inner cover 11 can be threadedly connected.

During use, the outer cover 12 is rotated so that the inner cover opening 111 communicates with the outer cover opening 121 and is aligned with the object to be sterilized, and the switch 14 is turned on to perform sterilizing. When not in use, the opening 121 of the outer cover is not communicated with the opening 111 of the inner cover, so that even the ultraviolet light emitted by the ultraviolet light source 10 will be blocked by the outer cover.
