Description

A kind of high sensitivity ultraviolet phototube
Technical field
The invention belongs to photoelectric tube technical field, more particularly to a kind of high sensitivity ultraviolet phototube.
Background technology
Ultraviolet is the general name that electromagnetic spectrum medium wavelength is radiated from 10nm to 400nm.In nature, main ultraviolet linear light Source is the sun, and wavelength is shorter than 290nm meters of ultraviolet by the ozone layer absorption in atmosphere when sunshine passes through atmosphere.It is ultraviolet Line has chemical action that photographic negative can be made photosensitive, and fluorescence is strong, fluorescent lamp and various fluorescent lamps be all excited with ultraviolet it is glimmering What stimulative substance lighted.Ultraviolet can be with false proof, and ultraviolet also has physiological action, can sterilized, sterilization, treatment skin disease and cartilage Disease etc..The corpuscular property of ultraviolet is stronger, and various metals can be made to produce photoelectric effect.But, being irradiated many ultraviolets can be to people Body health produces greatly harm, and such as injury eyes make skin produce erythema, or even induce cutaneum carcinoma.In life now, production Utilization to ultraviolet is a lot, so good ultraviolet phototube is particularly significant, in the prior art, the spirit of ultraviolet phototube Sensitivity is not universal high.
The content of the invention
The present invention goal of the invention be:In order to solve problem above present in prior art, the present invention proposes one kind Highly sensitive ultraviolet phototube.
The technical scheme is that:A kind of high sensitivity ultraviolet phototube, including housing, negative electrode, negative electrode pin, anode And negative electrode pin;The housing bottom is provided with firm banking;The negative electrode pin and negative electrode pin run through firm banking simultaneously It is fixed on firm banking;The negative electrode and anode include linear electrode section and the arc being connected respectively with linear electrode section two ends Shape canned paragraph, two arc canned paragraphs of the negative electrode are wired to angle with negative electrode pin and negative electrode pin respectively and are fixed on negative electrode On pin, two arc canned paragraphs of the anode, which are wired to angle with negative electrode pin and negative electrode pin respectively and are fixed on anode, to be drawn On pin, the linear electrode of the negative electrode and anode section is planar structure, the straight line of the linear electrode section of negative electrode parallel to anode Electrode section;Blast pipe is additionally provided with the middle part of the firm banking.
Further, the housing and firm banking use molybdenum group uviol material.
Further, the negative electrode and anode use metallic nickel materials.
Further, the firm banking passes through duration and degree of heating sealing-in with housing and blast pipe.
The beneficial effects of the invention are as follows:The high sensitivity ultraviolet phototube of the present invention is simple and compact for structure, uses and transports It is defeated all more convenient, and sound construction, it is hardly damaged.
Brief description of the drawings
Fig. 1 is the front view of the high sensitivity ultraviolet phototube of the present invention.
Fig. 2 is the top view of the high sensitivity ultraviolet phototube of the present invention.
Wherein, housing 1, negative electrode pin 2, negative electrode pin 3, anode 4, arc canned paragraph 4-1, linear electrode section 4-2 are fixed Base 5, blast pipe 6.
Embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, it is right below in conjunction with drawings and Examples The present invention is further elaborated.It should be appreciated that specific embodiment described herein is only to explain the present invention, not For limiting the present invention.
As shown in figure 1, the front view of the high sensitivity ultraviolet phototube for the present invention.A kind of high-sensitivity ultraviolet electricity Pipe, including housing 1, negative electrode, negative electrode pin 2, anode 4 and negative electrode pin 3;The bottom of housing 1 is provided with firm banking 5;Institute Negative electrode pin 2 and negative electrode pin 3 are stated through firm banking 5 and is fixed on firm banking 5;The negative electrode and anode 4 are wrapped Include the linear electrode section 4-2 and arc canned paragraph 4-1 being connected respectively with linear electrode section 4-2 two ends.As shown in Fig. 2 being this hair The top view of bright high sensitivity ultraviolet phototube, two arc canned paragraphs of the negative electrode respectively with negative electrode pin 2 and anode Pin 3 is wired to angle and is fixed in negative electrode pin, two arc canned paragraph 4-1 of the anode respectively with negative electrode pin 2 and Negative electrode pin 3 is wired to angle and is fixed in negative electrode pin 3, and the linear electrode section 4-2 of the negative electrode and anode 4 is planar knot Structure, the negative electrode linear electrode section parallel to anode linear electrode section 4-2;The middle part of the firm banking 5 is additionally provided with Blast pipe 6.
Housing 1 and fixed bottom in the ultraviolet produced when can simulate carbon compound burning due to uviol, the present invention Seat 5 is made of molybdenum group uviol materials, in addition can also use quartz glass, negative electrode and anode 4 use by Spectral region is by being made more than producing photoelectric metallic nickel materials in 190nm.Blast pipe 6 is shaped as cone, and position On center line between negative electrode and anode 4.Negative electrode pin 2 and negative electrode pin 3 are in parallel state, and made using teleoseal Form.
The course of work of ultraviolet phototube of the present invention is:
First, positive voltage is added in negative electrode pin 3, negative voltage is added in negative electrode pin 2, it is purple when there is ultraviolet irradiation Outside line is irradiated on the linear electrode of negative electrode section 4-2 through housing 1, the linear electrode of negative electrode section 4-2 occur photoelectric effect so as to Launch photoelectron, photoelectron is moved due to the effect of electric field force to the linear electrode section 4-2 of anode 4, by the linear electrode of anode 4 Section 4-2 absorbs, so as to produce electric current, simultaneously because voltage is acted on, the linear electrode section for having electronics to be moved to negative electrode again supplements cloudy The linear electrode section 4-2 of the loss of electrons of pole, negative electrode and anode 4 is planar structure, increases electric current, so that photoelectric tube is clever Sensitivity is higher.The linear electrode section of negative electrode is parallel with the linear electrode section 4-2 of anode 4, and Electric Field Distribution is more equal between making the two poles of the earth It is even.Anode 4 and negative electrode are a simple metal line, just very simple and saving material when so making photoelectric tube.Housing 1 is with fixing Base 5 constitutes an entirety, makes ultraviolet photoelectric tubular construction more firm, is hardly damaged.
One of ordinary skill in the art will be appreciated that embodiment described here is to aid in reader and understands this hair Bright principle, it should be understood that protection scope of the present invention is not limited to such especially statement and embodiment.This area Those of ordinary skill can make according to these technical inspirations disclosed by the invention various does not depart from the other each of essence of the invention Plant specific deformation and combine, these deformations and combination are still within the scope of the present invention.
