The present invention relates to a toothbrush sterilizer stabilizer circuit device, and more particularly, to a toothbrush sterilizer stabilizer circuit device capable of automatically disinfecting and disinfecting UV light for a certain time while maintaining the toothbrush hygienically.

In addition, the conventional toothbrush sterilizer stabilization circuit device did not have a function of automatically operating and stopping by sensing the external light.

Accordingly, the present invention has been made to solve the above problems, to provide a toothbrush sterilizer stable circuit device that can achieve a short-circuit prevention, waterproof and extended life and miniaturization by using the external and the sensing circuit unit and the constant voltage (thermal) ballast.

In addition, the DC voltage converter circuit unit 30 has a diode bridge rectifier circuit and a capacitor C ₃ connected in parallel, one end of which is connected to the AC power supply 10 through the capacitor C ₁ , and the other end of the DC voltage converter circuit unit 30 has an external and sensing circuit unit. It is configured to be connected to one end of the triac Q ₁ of (20).

Meanwhile, the timer switch circuit unit 40 is connected in parallel with the relay 1RE1 42 in a state in which the resistor R ₄ and the resistor R ₅ are connected in series to the first batter of the integrated circuit IC 48. Relay (relay) 1 RE1 (42) is connected in parallel with the DC voltage converter circuit section 30, one end of the resistor (R ₄ ) is connected to terminals 5 and 6 of the integrated circuit (IC, 48), respectively Connected to a resistor (R8) and a relay (relay) 2RE2 (46), a resistor (R ₆ ) and a capacitor (C ₄ ) are connected to terminals 2 and 4 of the integrated circuit (IC, 48), respectively. The resistor R ₆ and the capacitor C ₄ are interconnected in series, while the third terminal of the integrated circuit IC 48 passes through one end of the resistor R ₅ and one end of the relay 1 RE1 42. It is connected to the DC voltage converter circuit unit 30, a resistor (R ₇ ) is connected to the terminals 7 and 8 of the integrated circuit (IC, 48), one end of the relay contact RE1 '(44) is an integrated circuit ( Line connected to terminal 3 of IC, 48) Connected and the relay contact RE1 'the other end of 44 is connected to a resistor (R _7), the integrated circuit connection lines and the resistance (R ₇₎ and relay contacts RE1 of four times of the terminals (IC, 48)' (44) to And a relay contact RE2 '47 is connected between the other end of the germicidal fluorescent lamp unit 60 and an AC power supply 10.

In addition, the ballast circuit portion 50 is formed by connecting the capacitor (C0) and transformer (ST) in series is a sterilizing fluorescent lamp unit 60 consisting of a germicidal fluorescent lamp (UV LAMP, 62) and a glow starter lamp (64). Is connected between one end and the AC power supply 10, and is configured.

When the circuit operation according to the circuit configuration described in detail, when the user goes out of the bathroom after brushing the brush to turn off the light, the external light sensing circuit unit (CDS, 20) that changes its resistance value according to the brightness of the light is When the external light is dark, the resistance value of the resistor R ₃ is changed to the maximum (infinity) value, so that the capacitor for operating the die diode Q ₂ , which is the trigger diode, is connected to the capacitor C ₁ connected to the power supply unit 10 ( C ₂ ) and the charge / discharge time constant of the resistor R ₁ generate a pulse, which is a trigger diode, and the diac Q ₂ generates a pulse, and the generated trigger pulse voltage of the triac Q ₁ is an AC solid state switch. The triac Q ₁ is supplied to the gate, and the AC power is supplied through the capacitor C ₁ connected to the power supply unit 10 at both ends of the diode bridge rectifier circuits D1 to D4 which are the DC voltage converter circuit section 30. 10) is connected, where the bridge The capacitor C ₁ connected to the current power supply 10 passes the appropriate current and voltage required by the timer switch circuit unit 40 and the relay circuit (RE1, RE2, IC, etc.) to prevent wear of the component due to overvoltage and overcurrent. To prevent it.

Therefore, DC voltages are generated at the anode points P1 and P2 of the electrolytic capacitor C ₃ , but the AC power supply 10 is not changed into a perfect DC power by the electrolytic capacitor C ₃ . DC power is supplied to both ends of the RE1 42 and the integrated circuits IC and 48 of the timer switch circuit unit 40, and the integrated circuit IC of the timer switch circuit unit 40 is relayed by the relay contact RE1'44. , The start voltage for the operation of the 48 is applied to the integrated circuit (IC) 48, and the integrated circuit (IC) of the timer switch circuit unit 40 applied with the start voltage through the relay contact RE1 ′ 44. , 48) is operated for a certain time.

At this time, when the integrated circuit IC 48 of the timer switch circuit unit 40 is operated, the relay contact RE2 '47 connected to the integrated circuit IC 48 of the timer switch circuit unit 40 is operated. AC power is supplied to the stabilization circuit part 50 of the germicidal fluorescent lamp (UV LAMP) 62 and connected to the germicidal fluorescent lamp part 60 supplied with the AC power by the relay contact RE2 '(47). (C0) and the trans (ST) and the sterilizing fluorescent lamp (UV LAMP, 62) is turned on by the operation of the GLOW LAMP (GLOW LAMP, 64) to sterilize for a predetermined time, the timer switch circuit portion 40 After a predetermined time has elapsed according to the time constant, when the operation of the integrated circuits IC and 48 is completed, the relay RE2 46 connected to the output side of the integrated circuit IC 48 is restored. At this time, the relay contact RE2 '( 47) is cut off due to the recovery of the relay RE2 and also cut off the power of the fluorescent lamp 60 for sterilization Since it allows sterilizing the fluorescent lamp 62 for myeolhwa.

In addition, since it is widely known that the germicidal fluorescent lamp 62 is turned on during the operation of the timer switch circuit unit 40, the effect on the human body is very harmful when the ultraviolet light is emitted. In order to compensate, when the sterilizing fluorescent lamp 62 is turned on, when bright light is applied to the present invention, the external light sensing circuit unit (CDS, 20), which always detects light, automatically changes the resistance value to a minimum. Since both ends of the diac (Q ₂ ), which is the trigger diode, minimize the voltage. At this time, the diac (Q ₂ ), which is the trigger diode, stops its operation, and the triac (Q ₁ ) is an AC solid state switch. ) Will stop working. In addition, when the triac Q ₁ , the AC contactless switch, stops the operation, the power supply of the diode bridge rectifier circuit, the DC voltage converter circuit unit 30, is cut off, and at the same time, the timer switch circuit unit 40 required for sterilization operation When the operation of the timer switch circuit unit 40 stops, the DC power supply of the relay RE2 46 connected to the integrated circuit 48 is also cut off, so that the relay RE2 46 recovers and at the same time, the fluorescent lamp circuit for sterilization. Since the AC power of the ballast circuit unit 50 connected to 60 is extinguished by the blocking of the relay contact RE2 '47, the human body will not be directly or indirectly exposed to ultraviolet rays.

As described above, the present invention obtains the effect of preventing leakage and waterproofing by using the external and the sensing circuit unit 20 and the constant voltage stabilizer, and at the same time, the effect of miniaturization due to the extension of the life due to the voltage unchanged and the reduction of the circuit elements. In addition, since it is automatically turned on and off by the external light and the automatically set time, it is a very useful design that the user can easily operate and use.
