Description
Technical field
This utility model belongs to ultraviolet disinfection sterilization field, relates in particular to a kind of portable UV-LED disinfection pen.
Background technology
Traditional sterilizing ultraviolet source is low pressure mercury lamp, notification number is that the Chinese patent literature of CN2887310Y discloses a kind of Portable ultraviolet disinfector, its light source is low pressure mercury lamp, the dominant wavelength of low pressure mercury lamp is generally 253.7nm, large owing to the low pressure mercury lamp volume, voltage request is high, frangible, the reason such as caloric value is large, has limited low pressure mercury lamp in applications such as portable, small-sized, battery powered, responsive to temperature, fields.
The utility model content
Find after deliberation, the ultraviolet of some wavelength can destroy the dna structure of antibacterial or virus, playing the disappear effect of bacterium of virus killing, adopting wavelength is ultraviolet light that the UV-LED of 250nm to 300nm the sends nucleic acid (DNA (deoxyribonucleic acid) DNA, RNA (ribonucleic acid)) that acts on microorganism etc., but the chemical bond of saboteur's chain, thereby destroy or revise the chemical constitution of cell, good sterilizing effect is arranged, consider the luminous efficiency of present UV-LED, near the UV-LED sterilization effect the centre wavelength 265-280nm is best.UV-LED has that volume is small and exquisite, low-voltage DC supply, caloric value are low, shock-resistant, the characteristics of Portable belt, the ultraviolet-sterilization sterilization that is particularly suitable for making the occasions such as portable, small-sized, battery powered, temperature-sensitive material, field is used, with regard to ultraviolet-sterilization sterilization light source, be that the low pressure mercury lamp that generally uses at present fine replenished and perfect.
This utility model is that to adopt wavelength be that the UV-LED of 250nm to 300nm is that ultraviolet source substitutes low pressure mercury lamp, and adopting UV-LED to substitute low pressure mercury lamp has following benefit as ultraviolet source in the sterilizing field:
1, UV-LED is that low-voltage direct drives, and safety is reliable, can battery powered, be fit to portable equipment and field usage.
2, the UV-LED volume is small and exquisite, is easy to realize portable Miniaturization Design.
3, UV-LED is more energy-conservation than low pressure mercury lamp, long service life.
4, UV-LED is solid light source, and is shockproof durable, and low pressure mercury lamp is the glass tubing structure, frangible not being durable.
5, UV-LED is cold light source, is fit to the sterilizing of heat-sensitive material.
The technical scheme that its technical problem that solves this utility model adopts is:
A kind of portable UV-LED disinfection pen, having battery compartment, on and off switch, at least one emission wavelength is the UV-LED luminescence chip of 250～300nm, described portable UV-LED disinfection pen has the liquid level sensor for detection of liquid level.Described portable UV-LED disinfection pen preferably has foldable structure.Described UV-LED luminescence chip can be positioned on the part of foldable structure, and described battery compartment is positioned on another part relative with a described part of foldable structure with on and off switch.The UV-LED luminescence chip that described at least one emission wavelength is 250～300nm is preferably ranks and arranges, and identical with the direction of extension of described liquid level sensor, arranges for parallel.Described UV-LED luminescence chip is preferably single-row.Described luminescence chip is preferably the UV-LED luminescence chip that emission wavelength is 265～280nm.Described UV-LED luminescence chip can be designed to be positioned at the protection bottom portion of groove on portable UV-LED disinfection pen surface.The piezoid that covers described UV-LED luminescence chip also can be arranged in the described protection groove, and the outer surface of described piezoid is concordant with the outer surface of described portable UV-LED disinfection pen.This portable UV-LED disinfection pen also can have the intervalometer for the control disinfecting time.

The specific embodiment
Portable UV-LED disinfection pen shown in Figure 1 has foldable structure 3; foldable structure 3 makes the disinfection pen volume less; the convenient sterilizing pen carries; the part of the foldable structure 3 of disinfection pen has UV-LED luminescence chip 4; send ultraviolet light; in order to sterilizing; UV-LED luminescence chip 4 is single-row arrangement; and be positioned at linear type protection bottom portion of groove; also can cover the piezoid 6 of protection and waterproof action on the UV-LED luminescence chip 4 of bottom portion of groove; the ultraviolet light that this piezoid 6 sends for UV-LED luminescence chip 4 is transparent; also has the liquid level sensor 5 that be arranged in parallel with single-row UV-LED luminescence chip 4 on the described part of foldable structure 3; in order to detect liquid level, the luminescence chip below liquid level 4 just can send ultraviolet light thereby only make.Have battery compartment 2 and on and off switch 1 on another part relative with a described part of foldable structure 3, battery compartment 2 internal batteries, for disinfection pen provides electric energy, on and off switch 1 is used for control luminescence chip duty.
Glove should be worn in case ultraviolet light hurts hand skin during use, disinfection pen is put into the cup that fills the liquid such as beverage, press on and off switch 1, when filling liquid in the cup, then liquid level sensor 5 detects liquid level, luminescence chip 4 under liquid level can light after the delay several seconds, sends ultraviolet light liquid sterilization is sterilized; Or in empty cup, put into disinfection pen, then in empty cup, inject the liquid that needs sterilization, start working after luminescence chip postpones the several seconds when liquid level sensor 5 detects liquid level and covers luminescence chip 4 liquid is carried out disinfection, luminescence chip 4 can quit work automatically after work a period of time, take out disinfection pen, remove properly collection behind the liquid of surface attachment.At this moment, the structure of antibacterial and virus is destroyed in the liquid, and sterilizing is finished, and can relievedly drink.
