Description

Spherical ultraviolet fulgurite
Technical field
The utility model relates to photoelectric tube field, especially a kind of ultraviolet fulgurite.
Background technology
Ultraviolet ray is the general name of electromagnetic spectrum medium wavelength from 10nm to 400nm radiation.At occurring in nature, main ultraviolet light source is the sun, and the ultraviolet ray that when sunlight sees through atmosphere, wavelength is shorter than 290nm rice is absorbed by the ozone layer in atmosphere.Ultraviolet ray has chemical action can make photographic negative sensitization, and fluorescence is strong, and fluorescent lamp and various fluorescent lamp are all luminous with ultraviolet ray excited fluorescent material.Ultraviolet ray can also be false proof, and ultraviolet ray also has physiological action, energy sterilization, sterilization, treatment skin disease and osteomalacia etc.Ultraviolet corpuscular property is stronger, can make various metals produce photoelectric effect.But, irradiate too much ultraviolet ray meeting health is produced to harm greatly, as injury eyes, make skin produce erythema, even bring out cutaneum carcinoma.A lot of to ultraviolet utilization in life now, production, so good ultraviolet fulgurite is very important, but the sensitivity of prior art middle-ultraviolet lamp photoelectric tube is generally not high.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of high-sensitive ultraviolet tube.
The disclosed spherical ultraviolet fulgurite of the utility model, comprise housing, anode and negative electrode, described anode and negative electrode are positioned at housing, described housing is spherical, described anode comprises anode electrode section and anode-supported section, described negative electrode comprises cathode electrode section and cathode support section, described anode electrode section is parallel with cathode electrode section, described spherical ultraviolet fulgurite comprises two anode pins and two negative electrode pins, two anode pins are connected with the two ends of anode respectively, two negative electrode pins are connected with the two ends of negative electrode respectively, described anode and negative electrode are made by same material.
Preferably, described anode pin and housing intersection and negative electrode pin and housing intersection are provided with protective sleeve.
The beneficial effects of the utility model are: this ultraviolet fulgurite can add at negative electrode two ends different voltage, make negative electrode form electric current, improve the electronics liveness of negative electrode, make it that photoelectric effect more easily occur, thereby improve photocell sensitivity; Simultaneously anode is consistent with cathode construction, and the material of employing too, makes negative and positive the two poles of the earth can exchange use, convenient while not only installing, and need not consider polarity problems, and can extend and use useful life.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model.
Fig. 2 is vertical view of the present utility model.
Mark in figure: 1 is housing, 2 is anode, and 201 is anode electrode section, and 202 is anode-supported section, and 203 is anode pin, and 3 is negative electrode, and 301 is cathode electrode section, and 302 is cathode support section, and 303 is negative electrode pin, and 4 is protective sleeve.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further illustrated.
As depicted in figs. 1 and 2, the disclosed spherical ultraviolet fulgurite of the utility model, comprise housing 1, anode 2 and negative electrode 3, described anode 2 and negative electrode 3 are positioned at housing 1, described housing 1 is spherical, described anode 2 comprises anode electrode section 201 and anode-supported section 202, described negative electrode 3 comprises cathode electrode section 301 and cathode support section 302, described anode electrode section 201 is parallel with cathode electrode section 301, described spherical ultraviolet fulgurite comprises two anode pins 203 and two negative electrode pins 303, two anode pins 203 are connected with the two ends of anode 2 respectively, two negative electrode pins 303 are connected with the two ends of negative electrode 3 respectively, described anode 2 is made by same material with negative electrode 3.In the course of the work, generally two anode pins 203 connected and add a high voltage, on two negative electrode pins 303, add respectively different low voltages, because negative electrode 3 both end voltage are different, negative electrode 3 will be because of voltage difference generation current, negative electrode 3 temperature are raise, electronics liveness improves, when having ultraviolet ray to irradiate, will there is photoelectric effect in negative electrode 3, utilizing emitted light electronics, due to the electric field force of the voltage difference generation of negative and positive two interpolars, anode 2 moves photoelectron, by anode 2, absorbed, thereby generation current, so just can detect ultraviolet existence.Because the electronics liveness of negative electrode 3 improves, institute, so that photoelectric effect more easily occurs for it, makes the sensitivity of ultraviolet fulgurite higher.Anode 2 is made by same material with negative electrode 3, so in use for some time, negative and positive the two poles of the earth is exchanged to the useful life of so just improving ultraviolet fulgurite.Spherical housing 1 is more conducive to ultraviolet irradiation and penetrating, and anode electrode section 201 is parallel with cathode electrode section 301 is conducive to photoelectronic movement and 2 pairs of photoelectronic absorptions of anode.
The high temperature that the pin of ultraviolet fulgurite and housing 1 intersection often easily produce because of electric current damages housing, so as optimal way, described anode pin 203 and housing 1 intersection and negative electrode pin 303 are provided with protective sleeve 4 with housing 1 intersection.Protective sleeve 4 is generally made by high temperature resistant and adiabatic material, thereby makes housing 1 be difficult for causing damage because of the high temperature that electric current produces.
