Abstract

It consists of cold cathode disc type glass device, transformer-less electronic glow-starting thick-film circuit for controlling ignition of said glass device and case for holding above mentioned devices. In the cold cathode disc type glass device, the inert gas is filled, to make it emit powerful bactericidal short wave ultraviolet ray with wave length of 2537 A and the component of light spectrum is as high as 90%. When emitting ultraviolet ray, the temp. rise is not large and it will not ionize the air to produce ozone. Said transformer-less electronic glow-starting thick-film circuit can produce the current-limiting action according to the non-linear characteristic of said glass device and send out the pulse high voltage current to trigger the glass device to emit ultra-violet ray.

Description

The low temperature ultra-violet rays therapeutic apparatus

The present invention relates to a kind of low temperature ultra-violet rays therapeutic apparatus, particularly relate to a kind of volume little, light, carry easily, ozone free produces, the low temperature ultra-violet rays therapeutic apparatus of safety durable.

Ultraviolet radiation has the sterilizing effect, some diseases there is excellent curative, ultra-violet rays therapeutic apparatus in the past is that the high pressure quartz lamp based on the mercury arc light discharge is a light source mostly, its power is up to extremely several kilowatts of several hectowatts, and most of effect consumption is on heat radiation, wavelength with better germicidal efficiency is the small part that the ultraviolet of 2537A only accounts for high-pressure mercury quartz lamp spectral energy, and because this high-pressure mercury quartz lamp is scorching hot state when lighting, must keep bigger distance with irradiation person during treatment, relatively must increase irradiation time, add transformer circuit and circulating water cooling system, make the very huge heaviness of entire ultraviolet line therapeutic apparatus volume, use very inconvenient.In addition, there was a kind of cold cathode lamp of the glow discharge based on hydrargyrum to produce ultraviolet as the therapeutic apparatus light source in the past, though temperature was not high when the fluorescent tube of this kind therapeutic apparatus used, but in the process of ultraviolet radiation, can produce intensive ozone because of the ultraviolet ionization air, not only unpleasant and health worked the mischief, and because of adopting the general transformator current-limiting circuit of boosting, have bigger volume, can't popularize use.

The object of the present invention is to provide a kind of volume little, in light weight, carry easily, ozone free produces, the low temperature ultra-violet rays therapeutic apparatus of safety durable.

The present invention gets following measure to reach above purpose:

Low temperature ultra-violet rays therapeutic apparatus of the present invention comprises that a cold cathode dish type glass devices, a control lights transless electronics build-up of luminance thick film circuit and a housing that is installed with aforementioned components of this glass devices, be filled with noble gas in this cold cathode dish type glass devices, it is a kind of cold-cathode gas diode, it has two pole plates, and the electric field between two pole plates makes ionized inert gas and produces aura; It is that a kind of consumed power is little, long service life, can launch the light source that to have strong bactericidal effect wavelength be the short wave ultraviolet of 2537A, and spectral component is up to 90%, when the emission ultraviolet, raise little because of temperature, so can not produce ozone by ionized air, this transless electronics build-up of luminance thick film circuit can produce metering function according to the nonlinear characteristic of this glass devices, and the output ripple high-voltage pulse current, to trigger glass devices emission ultraviolet; This electronics build-up of luminance thick film circuit is a kind of pulsation voltage-multiplying circuit, and the multilamellar boost pressure circuit that it is made up of resistance capacitance and diode is operated in the glow discharge section to keep described glass devices.

Above-mentioned low temperature ultra-violet rays therapeutic apparatus, its feature are that also the shell of described glass devices is made by titaniferous quartz glass.

Above-mentioned low temperature ultra-violet rays therapeutic apparatus, its feature are that also described electronics build-up of luminance thick film circuit is provided with a timing controller.

Effect of the present invention is as follows:

Because the present invention adopts gas pressure drop lower cold cathode diode glass devices so consumed power little, long service life is because glass devices adopts titaniferous quartz glass to make, so do not produce ozone during lighting; Safety durable, because transless in the electronic ignition circuit, therefore, this therapeutic apparatus volume is little, is easy to carry.

Below by most preferred embodiment and accompanying drawing low temperature ultra-violet rays therapeutic apparatus of the present utility model is elaborated:

Description of drawings:

Fig. 1 is the structural representation of this utility model preferred embodiment.

Fig. 2 is the circuit diagram of this utility model preferred embodiment electronics build-up of luminance thick film circuit.

As shown in Figure 1, be the structural representation of this utility model preferred embodiment, present embodiment comprises a cold cathode dish type glass devices 11, controls and light electronics build-up of luminance thick film circuit 12, timing controller 13 and a housing 10 that is installed with aforementioned components of this glass devices 11.

Cold cathode dish type glass devices 11 inside are filled with noble gas, it is the lower cold cathode ionic device of a kind of gas pressure drop, work in noble gas glow discharge section, can launch the wavelength with strong bactericidal effect is the short wave ultraviolet of 2537A, its spectral component is up to 90%, so have extraordinary medical effect, the starting voltage of this glass devices 11 is 2500V, running voltage is 500-800V, operating current is 3-6mA, 60 minutes temperature of successively-ignited raise less than 40 ℃, therefore must not add any chiller, 6000 hours its averages length of working life, dielectric insulating strength is greater than 1000V.And, because glass devices 11 shells adopt titaniferous quartz glass tube, so during lighting, do not have ozone generating.

As shown in Figure 2, its be transless electronics build-up of luminance thick film circuit 12 circuit diagram its be an a kind of pulsation volt circuit, it is made up of timing controller 13, resistance R, capacitor C element and diode D; Wherein resistance R is a current-limiting resistance, this circuit utilizes capacitor and diode to form the multilamellar boost pressure circuit, the input electricity is at 0～200V, this circuit is for having nonlinear load adaptivity metering function, just can in certain working range, adjust voltage automatically, discharge in the glow discharge section to keep glass devices 11, and, the output floating voltage of transless electronics build-up of luminance thick film circuit 12 is greater than 2500V, and can set the working time by timing controller 13, when arriving, just cuts off automatically the time, above-mentioned glass devices 11 is connected in the outfan of electronics build-up of luminance thick film circuit 12, because glass devices 11 is disk-shaped,, provide a suitably treatment working region so can concentrate ultraviolet emitting area.

As shown in Figure 1, present embodiment is arranged on cold cathode dish type glass devices 11, transless electronics build-up of luminance thick film circuit 12 and timing controller 13 in small-sized, the housing 10 that can hand, in the process of using, glass devices 11 can be stablized the short wave ultraviolet that emission wavelength is 2537A, and temperature raises and is no more than 40 ℃, so can directly carry out direct irradiation, and ozone free produces with hand-held firmly 10 pairs of local lesion of housing.

In sum, the utility model low temp. ultra-violet, really tool Have volume little, in light weight, carry easily, ozone free produces, safety durable Advantage.
