[Configuration] When the timer 2 is ON, the power supply unit 1 supplies the switching circuit 3 with a rectified and step-down DC power source from a commercial power source.

[Conventional technology]

Ozone (O ₂ ) is an allotrope of oxygen that reacts with and oxidizes many substances even under conditions where oxygen does not react, and is usually distributed over a thickness of about 20 km at an altitude of about 20 to 25 km above the ground. It is known that the ozone layer is This ozone can have powerful sterilizing, bleaching, and deodorizing effects by utilizing its oxidizing properties, but the ozone concentration near the ground surface is extremely low and it is almost impossible to collect and accumulate it. Therefore, several methods of artificially generating ozone have already been proposed. According to them, ozone can be generated through chemical reactions, optical reactions, electrolytic reactions, etc., but the most common method is the silent discharge method, which generates ozone through an electric discharge reaction, and various sterilization equipment, deodorization equipment, etc. are already available.

An embodiment of the ozone generator of the present invention will be described based on the drawings. FIG. 1 is a system block diagram showing a schematic configuration of this embodiment.

Consists of an ozone discharge port 8 that discharges ozone to the outside using air supplied from the pump 7. has been done.

Next, a specific electric circuit of this embodiment will be explained in detail based on FIG. 2. As shown in the figure, the electrical system of the ozone generator of this embodiment includes an AC power plug 1a, a timer 2, a fuse 1b, a noise filter 9, a power transformer 1c, a ditaflam air pump 7, a control IC 10, and a power transformer 1c. A 4-terminal diode 1d that performs bridge rectification from alternating current to direct current, a smoothing circuit 1e consisting of a capacitor and an impedance, a 4-terminal diode 1f, a Darlington switching circuit 3 that causes current to flow through transistors Q ₁ and Q ₂ according to the output signal of the control IC 10, and a vehicle. When a low voltage (approximately 12V) is applied to the primary coil by the switching operation of the Darlington switching circuit 3 in the ignition coil used for ignition of the engine (in this example, the one made by Nippondenso Co., Ltd. is used). An ignition coil 4 that generates a high induced voltage (approximately 10,000 V) in a secondary coil, and an ozone generator 5 that applies the high voltage generated by the ignition coil 4 to two electrodes to discharge it and generate ozone. It consists of Note that the control IC 10 is a well-known IC having a logic function of an AND gate or a NAND gate.

Next, the operation of this embodiment will be explained. When power is applied to the power supply unit 1 and the timer 2 is in the ON state, the power supply unit 1 first supplies a driving voltage to the control IC 10 and also applies an induced voltage to the primary side of the ignition coil 4. Here, when the NAND gate of the control IC 10 outputs a logic "0" signal, the transistors Q ₁ and Q ₂ are completely cut off and the switching circuit 3 is in the "closed" state, so that the ignition coil 4 is connected to the primary side. No current flows. When the NAND gate outputs a logic "1" signal from this state, Q ₁ and Q ₂ become saturated, and the Darlington-connected Q ₁ has a flow that flows not only between the base and emitter of Q ₁ but also between the base and collector. A current component is generated. In other words, due to the emitter voltage V _BE and collector voltage V _CE of Q ₁ with respect to ground, the base-collector region is forward biased along with the base-emitter region, and the switching circuit 3 becomes “open” and the primary voltage of the ignition coil 4 A current is passed through the side. In this way, by temporally controlling the logic "1" signal input from the control IC 10 to the switching circuit 3, a pulse voltage is generated on the primary side of the ignition coil 4, and a high voltage potential is generated on the secondary side. can be induced. Due to this action, the electrodes of the ozone generator 5 induce discharge and generate ozone.

A high voltage from the ignition coil 4 of the vehicle engine is applied to the discharge electrode of the component part 5. The discharge characteristics are very stable and ozone is easily generated. You will be able to do this. Furthermore, in this embodiment, the primary side of the ignition coil 4 The pulse voltage supplied to the circuit is applied via the Darlington switching circuit 3. This makes it possible to drive the ozone generator 5 with a small amount of electric power, compared to conventional It is also possible to significantly reduce power consumption compared to other ozone generators. Furthermore, the ozone generator with a built-in pulse power supply of this embodiment has a circuit in which a high voltage current flows. This minimizes the amount of circuitry and allows most of the drive circuit to be driven at low voltage. The durability of the circuit components is greatly extended, and the maintainability of the equipment is improved. has a number of features not found in conventional ozone generators, such as a significant reduction in running costs.
