Abstract
The utility model relates to a sterilization device, in particular to a safety ultraviolet sterilization bar. The safety ultraviolet sterilization bar comprises a hollow bar-shaped housing and a safety monitor device , wherein an ultraviolet lamp is arranged in the housing, a projection window fitting with the ultraviolet lamp is arranged on the abdomen surface of the housing, a handle is arranged at the rear end of the housing; the safety monitor device includes a controller and a human body detector, the controller is electrically connected with the human body detector and the ultraviolet lamp respectively and arranged in the housing, and the human body detector is arranged on the abdomen surface of the housing. When in use, the human body detector can immediately scan a human body signal and feed back to the controller when the human body enters the projection area formed by the ultraviolet lamp through the protection window by accident, and the controller can immediately cut off the ultraviolet lamp circuit; and the ultraviolet lamp circuit can be switched on until the human body detector detects no human body signals. Accordingly, the safety ultraviolet sterilization bar can effectively prevent the human body from being injured by ultraviolet rays.
Description
Technical field
This utility model relates to a kind of bactericidal unit, especially refers to safety ultraviolet disinfection rod.
Background technology
The disinfection by ultraviolet light sterilizing use is very wide, hospital, school, nursery school, cinema, bus, office, family etc., and it can purify air, and eliminates musty, inferiorly can also produce a certain amount of negative oxygen ion outward, and through the room of disinfection by ultraviolet light, air is pure and fresh especially.In view of the above, developed the sterilization rod that is suitable for domestic in the prior art, known its structure of ultraviolet disinfection rod mostly as shown in Figure 1, adopt the bar-shaped shell 1` of hollow, establish ultraviolet light 2` in the shell, ultraviolet light 2` can throw downwards from shell 1` abdominal part, and shell 1` establishes handle 3` in the rear end, holds handle 3` pending article surface of short range scanning in the projected area of ultraviolet light 2` during use and gets final product.
The principle of ultraviolet sterilization is: cell has a rule to the absorption line of light wave, ultraviolet at 250～270nm has maximum absorption, in fact absorbed ultraviolet acts on the cytogenetics material is DNA, it plays a kind of photochemical action, the energy of ultraviolet photon is absorbed by the base pair among the DNA, cause that hereditary material morphs, make the dead at once or irreproducible offspring of antibacterial, reach germ-resistant purpose.
Because ultraviolet can cell killing, so to note to shine directly into people's skin, especially people's eyes during disinfection by ultraviolet light, not look at fluorescent tube when ultraviolet germicidal lamp is lighted straight.But known ultraviolet disinfection rod but can't effectively prevent above-mentioned unexpected the generation.
The utility model content
This utility model provides a kind of safety ultraviolet disinfection rod for remedying the deficiencies in the prior art, has human body to cut off the power supply of ultraviolet light rod immediately in the ultraviolet scanning area in case detect.
For achieving the above object, this utility model has adopted following technical scheme.
Safety ultraviolet disinfection rod comprises the bar-shaped shell of hollow being provided with ultraviolet light in the shell that the shell outside of belly is provided with the projection window that cooperates ultraviolet light, and outer casing back is provided with the hands handle; Also be provided with safety monitoring device, safety monitoring device comprises controller and human body detector, and controller electrically connects with human body detector and ultraviolet light respectively; Controller is located in the shell, and the human body detector then is located at the shell outside of belly.
In use, if human body enters the projection area that ultraviolet light forms by projection window accidentally, the human body detector scans human body signal immediately and feeds back to controller, and controller then cuts off the ultraviolet light circuit immediately, does not have the human body signal feedback up to the human body detector and just recloses the ultraviolet light circuit.Take this, can realize effectively preventing ultraviolet accidental injury human body.
As improvement of the technical scheme, the human body detector is installed between handle and the projection window.
As improvement of the technical scheme, described human body detector is for adopting the probe of pyroelectric infrared sensor (PIR), the projection area that probe forms by projection window towards ultraviolet light.Human body all has constant body temperature, generally at 37 degree, so can send infrared ray about specific wavelength 10um, the infrared ray about the 10um that probe is launched by the detection human body and carry out work.And probe itself do not send out the radiation of any kind, and device power consumption is very little, and is cheap.
Preferable, the outside of belly of shell is provided with in the position that probe is installed towards the concave surface of ultraviolet light by the projection area of projection window formation, and probe is located in the concave surface.Concave surface can play fine converging action, has further improved detecting sensitivity.
Preferable, concave surface is being provided with protruding circle near handle one side, the projection area that the axis of protruding circle forms by projection window towards ultraviolet light, and probe is located in the protruding circle.The structure of protruding circle has effectively avoided probe disturbed by the outer human body signal of projection area that projection window forms by ultraviolet light, has guaranteed the effectiveness of monitoring.
Compare with prior art, the beneficial effects of the utility model are:
Simple in structure, dependable performance has human body to cut off the power supply of ultraviolet light immediately in case detect in the ultraviolet scanning area, effectively prevented because the operation accident causes the damage of ultraviolet to human body.

The specific embodiment
Below in conjunction with specification drawings and specific embodiments this utility model is further described; but the scope that this utility model is protected is not limited thereto, and the changes and improvements that those skilled in the art can run away with all should belong to protection category of the present utility model.
Safety ultraviolet disinfection rod comprises the bar-shaped shell 1 of hollow being provided with ultraviolet light 2 in the shell 1 that shell 1 outside of belly is provided with the projection window 3 that cooperates ultraviolet light 2, and shell 1 rear end is provided with handle 4; Also be provided with safety monitoring device, safety monitoring device comprises controller 5 and human body detector 6, and controller 5 electrically connects with human body detector 6 and ultraviolet light 2 respectively; Controller 5 is located in the shell, and 6 of human body detectors are located between shell 1 outside of belly upper handle 4 and the projection window 3.
Described human body detector 6 is for adopting the probe of pyroelectric infrared sensor (PIR), the outside of belly of shell 1 is provided with in the position that probe is installed towards the concave surface 11 of ultraviolet light 2 by the projection area of projection window 3 formation, probe is located in the concave surface 11, concave surface 11 is being provided with protruding circle 12 near handle 4 one sides, the projection area that forms by projection window 3 towards ultraviolet light 2 in the protruding circle 12 is located in the projection area that the axis of protruding circle 12 forms by projection window 3 towards ultraviolet light 2, probe.
