Brief description of the drawings
Fig. 1 is the front view that high sensitivity of the invention inflates ultraviolet phototube.
Fig. 2 is the top view that high sensitivity of the invention inflates ultraviolet phototube.
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.
Specific 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 used to explain the present invention, not
For limiting the present invention.
As shown in figure 1, inflating the front view of ultraviolet phototube for high sensitivity of the invention.A kind of high sensitivity inflation is purple
Outer photoelectric tube, including housing 1, negative electrode, negative electrode pin 2, anode 4 and negative electrode pin 3；The bottom of the housing 1 is provided with fixed bottom
Seat 5；The negative electrode pin 2 and negative electrode pin 3 through firm banking 5 and are fixed on firm banking 5；The negative electrode and anode
4 include the linear electrode section 4-2 and arc canned paragraph 4-1 being connected with linear electrode section 4-2 two ends respectively.As shown in Fig. 2 being
High sensitivity of the invention inflates the top view of ultraviolet phototube, two arc canned paragraphs of the negative electrode respectively with negative electrode pin
2 and negative electrode pin 3 be wired to angle and be 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 are wired to angle and are fixed in negative electrode pin 3, and the linear electrode section 4-2 of the negative electrode and anode 4 is equal
It is planar structure, linear electrode section 4-2 of the linear electrode of the negative electrode section parallel to anode；The middle part of the firm banking 5
It is additionally provided with blast pipe 6, housing 1 filled with inert gas.
Because uviol can simulate the ultraviolet produced when carbon compound burns, housing 1 and fixed bottom in the present invention
Seat 5 is made of molybdenum group uviol material, in addition can also use quartz glass, negative electrode and anode 4 use by
Spectral region is by more than producing photoelectric metallic nickel materials to be made 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 are made using teleoseal
Form.In order to increase the sensitivity of photoelectric tube, the present invention is also filled with inert gas in housing 1.
The course of work of ultraviolet phototube of the 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 to irradiate
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
Transmitting 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 move to negative electrode again supplements cloudy
The loss of electrons of pole, can collide in photoelectron moving process with inert gas in housing 1, make ionized inert gas, electricity
From the cation and electronics for producing electric current can again increased, so that photocell sensitivity is higher.Negative electrode linear electrode section with
The linear electrode section 4-2 of anode 4 is parallel, and Electric Field Distribution is more uniform between making the two poles of the earth.Anode 4 and negative electrode are a simple metal
Line, just very simple and material-saving when so making photoelectric tube.Housing 1 constitutes an entirety with firm banking 5, makes ultraviolet
Fulgurite structure is 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 according to these technical inspirations disclosed by the invention make it is various do not depart from essence of the invention other are each
