Abstract

The invention discloses a ray sterilizing light pipe. A semiconductor material of a tellurium-bismuth alloy obtained by adopting novel alloying technology is made into an emitter to generate a ray electron beam under high voltage driving so as to form a ray source; the emitter is placed in a high vacuum quartz glass tube to obtain a ray source with a certain direction by using a tungsten plate as a deflector and applying high voltage; and the electron beam which contains alpha and X rays can be made into a sterilizing appliance which is small in volume and easy to carry and move.

Description

Ray sterilizing light pipe

Technical field

The present invention relates to a kind of employing tellurium bismuth condensation material as the light pipe anode, use high voltage drive, make light pipe produce ray, reach the purpose of bacterium with ray.

Background technology

At present, popular in the world sterilization method and method are a lot, and work is as high temperature, high pressure, medicine, ultraviolet ray, cobalt ⁶⁰Sterilizing methods such as irradiation, all these, its operability is all very poor, limited by external condition, uses inconvenience, uses cobalt ⁶⁰Though sterilization is thoroughly, because roentgen dose X is big, need special equipment and place, can not arbitrarily move, therefore, using and protecting and bring a lot of inconvenience for people.

Summary of the invention

In order to overcome the deficiency on existing sterilization method and the method, according to the ray sterilizing principle, the present invention adopts new alloy technology, obtain tellurium bismuth alloy body, use this alloy body, place in the pocket vitreosil glass tube of φ 20mm * 70mm, make the ray light pipe, under high voltage drive, the anode electronics is to cathode flow, in flow process, can produce the ray of certain equivalent, and be uninterrupted release, a kind of radiographic source thus has been born, ray band α and x radiation quality that this radiographic source penetrates have certain penetration capacity, can comparatively complete sterilization.

The technical solution adopted for the present invention to solve the technical problems is: adopt the Buchholz protection melting technique; tellurium and light metal bismuth is synthetic; thereby obtain a kind of new semiconductor synthetic material; with the emission anode of this material as light pipe; apply under certain high voltage situation; can produce and discharge the electron beam that has α and x ray; to cathode motion; rising along with voltage; this electron beam can constantly be strengthened; movement velocity also can constantly be accelerated simultaneously; (voltage and transmitted intensity relation are seen Fig. 3) is when voltage rises to a certain degree; just enter saturation condition; anode can reduce or stop divergent bundle; according to this characteristic; in order to obtain more electron beam; improve anode useful life; we have selected optimum operating voltage according to performance diagram; in order to obtain the ray that majority is used by oneself, between anode and negative electrode, added the tungsten plate, most of ray electron beam is reflected outside the running orbit; use by oneself; so just obtain being used for the sterilization needs, certain limit has been arranged, had the radiographic source of certain orientation.

Because the operating voltage of ray light pipe is very high, electric current is less, so it is little to project into volume, the portable sterilizer tool of being convenient to move has designed the direct current supply by 12V for this reason, during work for 12V voltage being promoted, select the VMS transistor for use, voltage in the circuit and frequency of oscillation have directly been supplied with the voltage multiplie of being made up of high-voltage diode and high-voltage capacitance after the VMS pipe is handled, needed adjustable voltage when (see figure 2) has obtained ray tube work thus.

The invention has the beneficial effects as follows: because ray light pipe volume is little, the body adopting quartz glass is made, 10 ^-8Under the vacuum state, can produce lasting a large amount of ray, can play the large tracts of land lethal effect, but, therefore can not work the mischief, influence minimum human body because wavelength is longer, and penetration capacity is limited to mushroom.Circuitry is simple, and high pressure is easy to protection, and is safe and reliable.

Description of drawings

The present invention is further described below in conjunction with drawings and Examples.

Fig. 1 is a structure chart of the present invention;

Fig. 2 is a circuit diagram;

Fig. 3 is the performance diagram among Fig. 1.

Among Fig. 1,1 HV Terminal, 2 lead-in wires, 3 tellurium bismuth alloys emission anode, 4 quartz glass tube bodies, 5 filaments, 6 tungsten plates, 7 bases, 8 vacuum suction passages, 9 lead-in wires, 10 pins.

Embodiment

In Fig. 1, HV Terminal 1, lead-in wire 2 are connected with tellurium bismuth alloy emitter 3, and tungsten plate 6 is fixed on the lead-in wire 9, while and filament 5, and pin one 0 links respectively.

Be connected on the HV Terminal 1 obtaining high pressure in shown in Figure 2 during work, through going between 2 to tellurium bismuth alloy emitter 3, just can produce the ray electron beam through 6 pairs of filaments of tungsten plate 5 and lead-in wire 9, the negative electrode that pin one 0 is formed discharges, in discharge process, when a large amount of electron beams runs into the tungsten plate 6 of band angle, will be refracted out outside the quartz glass tube body 4, promptly be the bactericidal rays source that we need.

Base 7 is that twice of quartz glass made moulding, and vacuum suction passage 8 vacuumizes usefulness when producing light pipe, vacuumizes to finish the back sintering and seal.

Fig. 2 makes the ray light pipe can obtain the high voltage operate as normal and the line map that designs.

Fig. 3 is Fig. 1 light pipe voltage at work, the performance diagram that roentgen dose X presented.
