A voltage drop unit 2-1 and a zener diode D2 (D6) for lowering the DC power supply to a voltage of 5.1 V to 6.2 V and transmitting the dropped voltage of 5.1 V to 6.2 V to the oscillator IC1 described later. ) And a plurality of resistors (R2, R3, R4, R5, VR) and capacitors (C3, C4) connected to and controlled from 5.1V to 6.2V transmitted from the voltage drop section 2-1 to be described later.

On the other hand, as shown in Figure 5, the nitrate remover 12 uses a separation vessel to remove a small amount of nitric acid from the ozone gas generated from the ozone generator 10, the ozone in the vertical direction therein A gas pipe 12-1 having a predetermined length connected to the generator 10 is formed.

In addition, a discharge pipe 12-2 is formed at one side of the upper end of the separation vessel so that ozone gas may be discharged, and a discharge port 12-3 is formed at the lower end thereof so that nitric acid (Nox) may be discharged.

Referring to the operation of the medical device disinfection device using the titanium ozone generator configured as described above are as follows.

First, water is supplied to the contact tank tank 16 and the disinfection tank 18 through the water supply pipe 14.

And, when the water level sensor 20 installed in the middle of the disinfection tank 18 senses the water level of the disinfection tank 18, when the water level sensor 20 senses the water level of the disinfection tank 18 to the full water level, The water level sensor 20 sends a sensed signal to a controller (not shown).

At this time, the control unit sends a control signal to the valve installed on one side of the water supply pipe 14 to turn off the valve.

In addition, when water is supplied to the disinfection tank 18, water is supplied to the first connecting pipe 22 installed on the bottom surface of the disinfection tank 18.

On the other hand, the titanium ozone generator 10 generates ozone gas, which is transmitted to the nitrate remover 12.

At this time, the nitrate remover 12 separates pure ozone gas and nitric acid (Nox) from the ozone gas transmitted from the titanium ozone generator 10, and only pure ozone gas to the Venturi tube 26 according to the Bernoulli principle. Send it.

In particular, the water supplied to the first connecting pipe 22 is supplied to the venturi pipe 26 by pumping the first booster motor pump 24.

At this time, a vortex is generated inside the venturi tube 26, and pure ozone gas and water generated from the nitrate remover 12 are mixed (ozone water) by the vortex.

The ozone water mixed in the venturi tube 26 is transmitted to the amplifier 28 through the venturi tube 26.

The amplifier 28 crushes the particles of ozone water transmitted from the upper venturi tube 26 and mixes them with the surplus ozone gas again. The mixed ozone water is transferred to the contact tank tank 16 through the lower venturi tube 26. Send it.

At this time, the ozone water supplied to the contact tank tank 16 is separated into bubbles (eg ozone gas) and pure ozone water by water pressure.

Here, since the bubble is lighter than the ozone water, the bubble rises above the water surface of the contact tank 16, and the pure ozone water is mixed with the existing ozone water.

In particular, when the ozone water reaches a predetermined level or more through the venturi tube 26 to the contact tank tank 16, the ozone water is discharged to the disinfection tank 18 through the first discharge pipe (30).

At this time, if the medical device is placed in the disinfection tank 18, the medical device is sterilized by ozone water.

On the other hand, when disinfecting a large medical device, by operating the second booster motor pump 36 to pump the ozone water stored in the contact tank tank 16 through the second discharge pipe 34, the pumped ozone water The discharge to the third connection pipe 38 and the second valve 44 is turned on to discharge to the fourth connection pipe 48 having the injection nozzle 46 formed thereon.

At this time, the nozzle 46 allows ozone water to be injected into a large medical device placed in the disinfection tank 18, and increases the cleaning sterilization efficiency in the wave of ozone water.

Therefore, the medical device is disinfected by ozone water.

The operation of the ozone generator 10 is as follows.

First, the down transformer 1 receives a single-phase AC power of 220V to the primary coil and decompresses the single-phase AC power of 100V to the rectifier 2.

At this time, the rectifier 2 rectifies the 100 V single-phase AC power transmitted from the secondary coil of the down transformer 1 to DC 100 V and transmits the DC voltage to the boosting substrate 3.

The DC boosting substrate 3 boosts the 100V DC power source rectified and transmitted from the rectifying unit 2 to 30V to 100V DC and transmits the DC power to the ultra-high voltage transformer 4.

Here, the ultra high voltage transformer 4 receives a DC power supply of 30 V to 100 V as the primary coil and boosts the ultra high voltage DC power of 19000 V to 21000 V from the secondary coil, and converts the boosted ultra high voltage power of the cathode / anode high voltage wire ( 5, 6).

The high voltage wires (cathode wires, positive pole wires) 5 and 6 are attached to a close stainless spring 7-3 and an aluminum heat dissipation fin 7-5 formed on the titanium tube 7-1 of the ozone generator 7. Apply super high pressure to each.

Therefore, the discharge is generated in the discharge space (7-2) of the ozone generator (7), at this time, through the inlet (7-7) of the ozone generator (7) to the discharge space (7-2) DC 19000V ~ 21000V discharge when there is air flow, ozone gas is generated.

At this time, the ozone gas generated in the ozone generator 7 is discharged to the outside through the discharge port (7-13).

In particular, the heat generated from the ozone generator 7 is discharged through the aluminum heat dissipation fins 7-5 which are pressed outward by the titanium tube 7-1 forming the discharge space 7-2.

Looking at the operation of the DC boosting substrate in more detail as follows.

First, the voltage drop unit 2-1 uses a 100V DC power source rectified from a rectifier (not shown) and transmits the voltage to 5.1V to 6.2V using the Zener diodes D1, D2, D3, D4, and D5. In addition to the drop, the dropped voltage of 5.1V to 6.2V is transmitted to the oscillator (IC1).

In addition, the oscillator IC1 is controlled at 5.1V to 6.2V transmitted from the voltage drop unit 2-1 to the input terminal 7 pin and 450PPS for turning on the transistor Q1 through the output terminal 3 pin. Oscillate the pulse wave.

In addition, the transistor Q1 is turned on by the 450PPS pulsation wave transmitted from the oscillator IC1 and transmits DC power of 30V to 100V to the primary coil of the ultra-high voltage transformer 4.

Accordingly, the ultra-high voltage transformer 4 boosts the DC power of 30 V to 100 V transmitted to the primary coil to the ultra high voltage DC power of 19000 V to 21000 V in the secondary coil, thereby increasing the voltage of the high voltage wires (cathode wires and positive pole wires) (5, 6). The ultra-high voltage DC power supply of 19000 V to 21000 V is transmitted to the ozone generator 7 through.

As described above, the present invention can simply and safely disinfect and sterilize medical devices infected with viruses and bacteria.

In addition, the present invention has the effect that can be used simply and anywhere in the ultra-low power consumption and zero harmful state if there is only air, electricity and devices, and is a safe device that does not have any harmful from ozone gas even in an enclosed space.
