Problems solved by technology

[0002] After the electrical appliance is in standby, people tend to forget to turn off the power supply and do not pull out the plug. They are accustomed to letting the electrical appliance stand by. The long-term standby consumes power, which is not conducive to electrical maintenance. The power consumption also affects the life of the electrical appliance, and even causes accidents. This is because the power is not cut off. Caused

Embodiment Construction

[0013] Voice prompt device after the electrical appliance has been in standby for three minutes, such as figure 1 , figure 2 As shown, when the main control electrical appliance is turned off or in standby, and the output is less than the set power, a voice reminder will be given to enhance the energy-saving awareness of electrical appliance users and remind people to cut off the power supply. The device is composed of a power switch, a system power supply, a detection circuit, a delay control circuit, a voice circuit, an indicator light, a main control output terminal and an output terminal of peripheral electrical appliances.

[0014] Among them: K1 is the power switch, and the output terminal of peripheral electrical appliances can be connected with multiple electrical appliances. T1 uses a 6-12 V, power 4W power transformer; Q1 is a PNP transistor; C1-3 is an electrolytic capacitor, C4-5 is a ceramic capacitor, R1-7 is an ordinary resistor, D1-6 is a diode, and VD1 is a ...

Abstract

The invention discloses a voice prompting device for a three-minute standby electric appliance. The device is characterized by consisting of a power switch, a system power, a detection circuit, a time delay control circuit, a voice circuit, an indicator light, a main control output end and an external electric appliance output end. The control circuit is simple and mainly controls an electric appliance in an off or standby state, when an output power is less than a set power, voice is generated for prompting according to a required setting standby delay time, and the prompting voice can be recorded by users. The energy-saving consciousness of electric appliance users is increased, the users are prompted to cut off the power, and furthermore, a standby safety problem is solved. The device is particularly suitable for prompting the blind, the old and forgetful men, is suitable for a series of related standby energy-consuming electric appliances such as computers, multimedia systems, televisions, home audio systems, kitchen appliances and production and living electric appliances, and is used for prompting power cut-off operation and the like.

Description

Technical field: [0001] The invention belongs to the field of electronic control, and relates to a device for voice prompting people to cut off the power supply after the electric appliance is on standby. Background technique: [0002] After the electrical appliance is in standby, people tend to forget to turn off the power supply and do not pull out the plug. They are accustomed to letting the electrical appliance stand by. The long-term standby consumes power, which is not conducive to electrical maintenance. The power consumption also affects the life of the electrical appliance, and even causes accidents. This is because the power is not cut off. Caused. Invention content: [0003] The purpose of the present invention is to provide a device for voice prompting people to cut off the power supply after the electric appliance standby time delay; detecting the change of the current of the main control electric appliance load, when the main control electric appliance is shu...
