Abstract

PURPOSE:To obtain an electric power source for a detector and stopper for water flow, a bathtub buzzer, a chime for communication or the like safely and inexpensively, by obtaining the DC of a constant voltage by using the discharging of fluid. CONSTITUTION:An impeller 1 is rotated by the discharging of tap water and electricity is generated by a generator 2. The generated electricity is rectified with a rectifier circuit 3a and is charged with a charging circuit 3b. A light emitting diode D2 is kept lighted during generation of electricity with the genegrator 2. When the discharging of the tap water is stopped, no more electricity is generated and the charged electricity is supplied to an alarm circuit 4. The voltage supplied through the diode D1 is made zero, and a transistor Tr1 is turned off, then the base current of a transistor Tr2 is supplied for a specified time through a capacitor C1 to a buzzer BZ which sounds to announce the stoppage.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a power supply device for electrical equipment used in places around water such as bathrooms, kitchens, and toilets.

Examples of electrical equipment around plumbing include, in bathrooms, there are water flow detection and stop devices that measure the amount of water into the bathtub and stop it from flowing into the bathtub, and devices that have built-in dry batteries that can monitor the water volume, water temperature, and temperature. Is there something like a buzzer to notify you of this? The former has a mechanical structure and can only notify you, so you won't know when the water has stopped flowing, and the latter is battery-powered, so it cannot be used continuously and the battery It takes time to replace.

Another drawback is that the work of shutting off the water must be done manually.

SUMMARY OF THE INVENTION In view of the above-mentioned problems, an object of the present invention is to provide a power supply device that generates electricity using the discharge power of water used in places around water, stores the electricity, and emits a notification sound throughout the usage number.

1 to 2 of the embodiment of the present invention. FIG. 1 is a block diagram of the power supply device of the present invention, and the water discharge port is connected to the tap water outlet in a water area. A rotating impeller 1 is provided, and a generator 2 that generates electricity by the rotation of the impeller 1 is connected. A power supply circuit 3 is connected downstream of the generator 2. The power supply circuit 3 has a rectifier circuit 5a that rectifies the generated current when it is alternating current, a charging circuit 3b that stores the generated current, and a constant voltage circuit 30 that makes the subsequent notification circuit 4 a constant voltage. A notification circuit 4 is connected to a subsequent stage of the power supply circuit 3. The notification circuit 4 is connected to a constant voltage from the constant voltage circuit Sa. The notification circuit 4 uses a signal from the sensor circuit 5 or a power generation stop signal number to turn off the first transistor ``r'', a light emitting diode D to indicate that power is being generated, and a certain period of time after the first transistor ``lr'' is turned off. Only buzzer B7. It has a capacitor C for accumulating electricity and a transistor R. Buzzer BZ is transistor 'I
I make it so that it makes a sound every time the 'r is turned on.

To explain the operation of the above configuration, the impeller 1 rotates when tap water is discharged, the generator 2 generates electricity, the rectifier circuit 5m rectifies the water, and the charging circuit 5b charges the water. When the generator 2 is generating electricity, the transistor rr is turned on through the diode D. At this time, the light emitting diode D! lights up. Next, when the discharge of tap water stops, no power is generated, and the notification circuit 4 is supplied with power by the electricity charged in the charging circuit 6b. Since the voltage supplied via the diode D1 becomes zero, the first transistor ``rr1'' is turned off.
The base current of the transistor rr is supplied for a certain period of time via the capacitor C1 for power storage, and the buzzer BZ sounds to notify the user. When the sensor circuit 5 is installed, the signal via the da/f ode D can be the sensor (No. 8) of the sensor circuit 5.

The above configuration consists of an impeller that rotates due to the discharge of fluid, a generator that generates electricity from the rotation speed of the impeller, a power supply circuit, and an alarm circuit, and the power supply circuit includes a rectifier circuit that rectifies the generated current when it is alternating current. , a power supply device comprising a charging circuit that charges using generated current and a constant voltage circuit that makes the subsequent circuit a constant voltage, and the notification circuit is a circuit that sounds a buzzer for a certain period of time in response to a sensor circuit signal or a power generation stop signal. Therefore, water flow detection stoppers and bath buzzers, which are conventional electrical equipment used in plumbing, either only require mechanical deposition or require dry batteries, and are not suitable for use in bathrooms, kitchens, toilets, etc. Most of the communication chimes used in places like this used dry batteries, but if you use the power supply device of the present invention, you can hear 111 alarms when discharging tap water, etc. Since it stores electricity and supplies electricity from a storage power source, it is useful as it is a continuous, safe, and inexpensive power supply device that does not use dry batteries.
