Description

Energy-saving environment-friendly AC/DC quartz clock and watch wall clock

Technical Field

The invention relates to an AC/DC power supply quartz clock and watch wall clock and a circuit thereof.

Background

Quartz clocks sold in the market at present generally produce waste batteries, so that the environment is polluted; stopping frequently, needing to replace the battery frequently, checking time, and having trouble and error; the travel accuracy is unstable (mainly caused by the continuous reduction of the battery voltage, and finally the travel is stopped); the quartz clock with the noctilucent function has unsatisfactory noctilucent effect; some high-grade timepieces cannot improve performance and the like.

The invention solves the defects of the quartz clock wall clock.

Disclosure of Invention

The quartz clock wall clock is the most commonly used timing tool, all quartz clocks are almost powered by batteries, the batteries are required to be continuously replaced in the power supply mode except for generating waste batteries and polluting the environment, the time is frequently corrected, the work is mistaken, the time error is large along with the continuous reduction of the voltage of the batteries, and even the time is stopped. The clock with the noctilucent function is sensitive to light, is greatly influenced by illumination, and has an unsatisfactory noctilucent effect, so that the clock hands and time can be clearly seen in the first half night, and the clock hands and time can not be clearly seen in the second half night. Therefore, there is a need for an improvement in the art to address the above-mentioned disadvantages of existing quartz timepieces.

The invention adds an AC 220V power supply circuit and a noctilucent control circuit on the basis of the battery power supply of the original quartz clock movement, thereby improving the performance of the clock.

The alternating current power supply circuit is composed of a diode, a resistor, a capacitor, a voltage stabilizing diode and a miniature three-terminal power supply chip DC/DC (hereinafter referred to as a DC chip), 220V voltage is rectified by the diode, voltage is reduced and limited by the resistor, filtering is carried out by the capacitor, voltage stabilizing processing is carried out by a voltage stabilizing tube, the processed stable voltage is transmitted to the DC chip, the DC chip outputs 1.5V to a battery power supply end of the clock movement, and the DC chip is connected with the positive electrode and the negative electrode of the battery in parallel to supply power to the clock movement.

When the clock is switched on to 220V voltage, the 1.5V battery becomes a standby battery during power failure, and the battery does not need a rechargeable lithium battery or a nickel-hydrogen battery and only needs 1 section of 1.5V No. 5 common carbon battery. According to the principle that current flows from high voltage to low voltage, when the voltage of 1.5V generated by an alternating current circuit is consistent with the voltage of 1.5V of the No. 5 carbon battery (both are 1.5V), the No. 5 carbon battery can not be charged or discharged and is always in a standby state. In fact, through continuous development, improvement and use for nearly 10 years, 1 section of high-quality 5-carbon batteries can be kept for about 10 years without replacement, and the battery placement position does not need to be additionally arranged, and only needs to be arranged in a battery cabin of a movement of a quartz clock.

The technical circuit is suitable for various quartz clock movements (mute electric wave movement, mute second sweeping movement, second jumping movement and pendulum movement), and has the advantages of energy saving, environmental protection, convenience, accuracy and low cost, wherein 1. the circuit saves energy, reduces the number of elements as much as possible, simplifies the circuit and ensures that the power consumption is less under the condition of ensuring the output of pure 1.5V direct current voltage and meeting the loaded power. When the whole circuit works, only about 0.5mA of alternating current (the current of a high-quality quartz clock movement is as small as 0.3mA), only five or six gross dollars of electricity are charged in one year, and even less. 2. The circuit is powered by alternating current, so that the waste battery is avoided, the pollution to the environment is reduced, and the environment-friendly concept is met. 3. The method is convenient, eliminates the trouble, inconvenience and error caused by continuously replacing batteries, calibrating time and stopping time and time of the quartz clock, and saves time, labor and worry. 4. The accurate nature of walking time is stable, for battery powered, along with battery power reduces, and voltage constantly descends, and the error is also big when walking. The circuit is adopted for power supply, and the voltage is in a stable state for a long time, so that the travel accuracy of the clock is stable, and the travel error of the clock is greatly smaller than that of battery power supply. If the clock adopts the radio controlled movement, the time precision of the radio controlled movement is kept synchronous with the Beijing time for a long time, and the error is zero. 5. The invention has low cost, simple circuit, low element cost, safe and stable work and less failure rate.
