Abstract

The utility model relates to an ultraviolet sterilizer, which is composed of an upper cover and a chassis. The utility model is characterized in that the paraboloidal-shaped inner walls of the upper cover and the chassis are coated with a metal light reflection film. When the power supply is on, the utility model is matched with a disc-shaped ultraviolet sterilizer arranged in the upper cover to make light rays change into a parallel light; besides, the light is even and has no dead corner; the joint of the upper cover and the chassis are provided with a leakage-proof switch. When the upper cover and the chassis are not tightly closed, the power supply can not be on so as to effectively prevent the leaking of ultraviolet rays. A net-shaped frame is arranged in the chassis. The utility model can carry out sanitary sterilization of high efficiency and fastness for small articles, wares, appliances, dishware, fruits and other tools which are placed on the ultraviolet sterilizer.

Description

Ultraviolet sterilizer

This utility model has related to a kind of disinfecting device, particularly adopts the ultraviolet disinfecting device of ultraviolet radiation for sterilizing and disinfecting.

The current method that the sterilizing of small articles, articles for use, vessel, tableware and fruit is adopted usually solar radiation, washing or high-temperature sterilization.Solar radiation method time-consuming is long, and the washing method bactericidal effect is not obvious, and high-temperature sterilization easily makes article impaired, and the scope of application all has certain limitation.With " household ultraviolet disinfecting device " (number of patent application 92225300.5) is representative, has overcome the deficiency of above-mentioned technology, and a kind of technical scheme of utilizing ultraviolet to household supplies, apparatus sterilizing is provided.But what this patented technology adopted is a general ultraviolet line fluorescent tube, and shortcoming is to constitute directional light, and illumination is even inadequately, also exist ultraviolet radiation less than the dead angle; Ultraviolet leaked fail to provide the technical scheme of solution.

The purpose of this utility model is to avoid the deficiency of prior art, and a kind of new ultra-violet line disinfector is provided, promptly provide a kind of ultraviolet illumination evenly, do not leak, do not have the technical scheme at dead angle.

The purpose of this utility model can realize by following technical measures: this ultraviolet ray disinfector is made up of last cover and chassis two parts.The dish type Burdick lamp is suspended on the top of cover.Last cover inwall makes parabolic shape, and and the interior together plating reflective membrane in chassis.When energized, the ultraviolet that the dish type lamp sends makes light become directional light by the parabolic reflective metal film of disinfector inwall, behind multiple reflection, makes illumination more even again, and is unglazed according to the dead angle, improved Disinfection Effect.In addition, last cover and junction surface, chassis are provided with anti-lets out switch, have only when upper cover well after circuit could connect, prevented that effectively ultraviolet from leaking.Be provided with netted in the chassis, be used for holding the article that are sterilized.Drip in order to temporarily to deposit a little that be sterilized vessel and fruit to netted space in the chassis.

This utility model compared with prior art has tangible technique effect: one, adopt the dish type Burdick lamp, and make light even, reduced the illumination dead angle; Its two, the inwall of the paraboloidal on last cover and chassis plates reflective metal film, cooperates the dish type Burdick lamp to become directional light, illumination is more even, Disinfection Effect has been improved at unglazed photograph dead angle; Its three, the anti-switch of letting out at last cover and junction surface, chassis can prevent effectively that ultraviolet from leaking.

Description of drawings is as follows:

Fig. 1 disinfector schematic cross section

Fig. 2 disinfector circuit diagram

Sequence number is as follows among the figure:

The last cover of 1-; The 2-chassis; 3-dish type fluorescent tube; The 4-reflective metal film; The anti-switch of letting out of 5-; Netted of 6-; The 7-on and off switch; 8-is alarm then; The 9-intervalometer; The 10-starter; The 11-electric ballast; The 12-handle

, be described further this utility model below in conjunction with drawings and Examples.

See figures.1.and.2, on cover 1 and chassis 2 usefulness commaterials (as engineering plastics, glass or a kind of jade porcelain etc.) make, their inner wall shape is parabolic, simultaneously the plating reflective membrane.Dish type fluorescent tube 3 is suspended on the top of cover 1.The joint on last cover 1 and chassis 2 is provided with the anti-switch 5 of letting out.Be provided with netted 6 in the chassis.When put well on netted be sterilized article after, build the cover 1.When last cover was tight with chassis joint lid, it was not closed to prevent letting out switch 5, and disinfector can not be worked, and ultraviolet does not leak in the time of can preventing the disinfector operate as normal effectively like this.Mix up intervalometer 9 time limit of alarm 8 then subsequently, start on and off switch 7, starter 10 starting the arc, dish type fluorescent tube 3 is bright, the disinfector operate as normal.What this utility model adopted is Low-voltage Electronic ballast 11, and its effect is that the dish type fluorescent tube can normal starting when 170-230V for the assurance scope range of the fluctuation of voltage.After the dish type lamp was bright, the reflective metal film of the parabolic inwall plating on last cover and chassis made light become directional light, makes illumination even, no dead angle.Sterilization finishes, and intervalometer 9 is cut off the electricity supply automatically, and alarm 8 is reported to the police with acoustooptic form.

What this utility model adopted is dish type ultraviolet sterilization fluorescent tube, can give off intensive 2537A wavelength ultraviolet, and can be by born of the same parents' albumen of antibacterial and nuclear oxygen ribose (D.N.A) strong absorption, makes their key be opened and makes antibacterial death.Can adjust the time limit of intervalometer 9 during application according to the pollution level that is sterilized article.Adjusting range is 3-90 minute.

Claims

A kind of new ultra-violet line disinfector is characterized in that, the upward cover and the chassis of disinfector are coated with reflective metal film, and its inwall is parabolic shape.
