Abstract
The invention discloses a power-off alarm which comprises a life and industrial power utilization circuit, a relay and an alarm circuit. The power-off alarm is characterized in that the alarm circuit comprises a low-voltage power supply, a buzzing alarm and an indicating lamp, and the relay plays the role of a switch in the two circuits, namely, the relay serves as the switch of the alarm circuit when powered off, and serves as the switch of the life and industrial power utilization circuit when powered on. The power-off alarm is simple and reasonable in design, and can raise the alarm the moment that the life and industrial power utilization circuit is powered off.
Description
Technical field
The present invention relates to a kind of power-off alarm.
Background technology
Well-known electricity has become indispensable in our life; power failure phenomenon is often there will be under current energy-intensive situation; we want the very first time know power-off, the generation of power-off event just needs power failure alarm device; also some power failure alarm devices are had in the market; but be mostly that design is complicated, expensive.
Summary of the invention
For solving above-mentioned existing shortcoming, fundamental purpose of the present invention is the power-off alarm providing a kind of practicality, and simplicity of design is reasonable, can after the power-off of Living Industry power circuit the very first time warn to people.
For reaching above-described object, a kind of power-off alarm of the present invention takes following technical scheme:
A kind of power-off alarm, comprise Living Industry power circuit, relay and warning circuit, it is characterized in that, described warning circuit comprises low-tension supply, buzzer siren and pilot lamp, described relay serves as on-off action in described two circuit, serve as warning circuit switch when power is off, during not power-off, serve as Living Industry power circuit switch.
Adopt the present invention of as above technical scheme, there is following beneficial effect:
Relay serves as warning circuit switch when power-off, serves as Living Industry power circuit switch during not power-off.Simplicity of design of the present invention is reasonable, can after the power-off of Living Industry power circuit the very first time warn to people.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
In order to further illustrate the present invention, be described further below in conjunction with accompanying drawing:
As shown in Figure 1, a kind of power-off alarm of the present invention, comprise Living Industry power circuit 1, relay 3 and warning circuit 2, wherein warning circuit 2 comprises low-tension supply 6, buzzer siren 4 and pilot lamp 5, and relay 3 serves as on-off action in two circuit, serve as warning circuit 2 switch when power is off, during not power-off, serve as Living Industry power circuit 1 switch.
