Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

It will be understood that when an element is referred to as being "disposed" or "connected" to another element, it can be directly on the other element or intervening elements may also be present.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

The utility model provides a specific scheme of low pressure user household line fault prompting device that the utility model provides is explained with reference to the attached drawing in detail below.

Please refer to fig. 1, which shows a block diagram of a low voltage user household circuit fault indicator according to an embodiment of the present invention, when the household electrical appliance is not powered on, it is often necessary to try to determine whether other electrical appliances work normally, in order to solve the problem of making the user quickly determine the fault reason, the utility model discloses at the demarcation point where the public circuit is connected to the household electrical circuit through the electric energy meter, an indication loop using the magnetic reed switch 100 as the main component is provided, the indication loop includes an indication loop formed by connecting the magnetic reed switch 100, the power supply 200 and the indicator 300 in series, wherein, the magnetic reed switch 100 of the indication loop is installed at a position close to the electric energy meter.

Specifically, the power supply 200, the reed switch 100, and the indicator light 300 are connected in series to form an indicator circuit, and the reed switch 100 is installed at a position close to the electric energy meter 30. Under the condition that the household line 20 is normally conducted, a magnetic field is generated around the household line 20, the reed switch 100 in the magnetic field is magnetized, different-name magnetic poles are formed on two reed end faces of the reed switch 100 and attract each other, so that the reed switch 100 is switched on, a normal indicating loop is conducted, and the indicating lamp 300 is lightened; in turn, the indicator light 300 lights, indicating that the reed switch 100 is on, and that conduction between the electric energy meter 30 and the household line 20 is occurring. In the event of a line fault in the home, the magnetic field disappears, reed switch 100 opens, and indicator light 300 goes off, indicating that the line has failed.

In summary, the embodiment of the present invention provides a household line fault prompter for low-voltage users, in which a reed switch is disposed at a position close to an electric energy meter, and the reed switch is connected to a loop connected with an indicator light, so that the indicator light is turned on when the circuit is in normal operation, the indicator light is turned off when the circuit is in fault, and when the indicator light is turned off, the household line is indicated as in fault.

Please refer to fig. 2, which shows a schematic circuit diagram of a low voltage user household circuit fault prompter provided by an embodiment of the present invention, the fault prompter includes an indication loop formed by connecting a magnetic reed switch S1, a power VCC, and a light emitting diode LED1 in series, the magnetic reed switch S1 is disposed near the electric energy meter E1, under the condition that the household circuit normally works, a magnetic field is generated around the electric energy meter, the magnetic reed switch S1 is magnetized and then attracted, the indication loop is conducted, and the light emitting diode LED1 emits light; when the household line has a fault, the magnetic field disappears, the magnetic reed switch S1 is switched off, the indicating loop is switched off, and the light-emitting diode LED1 does not emit light; whether the household line is in failure is judged through the light emitting condition of the light emitting diode LED 1.
