Supply voltage sampling module and provide mains voltage sampling module for oneself including the commercial power, the commercial power is supplied voltage sampling module and is provided mains voltage sampling module for oneself and is connected with relay switch conversion module respectively, the commercial power is supplied voltage sampling module and is provided mains voltage sampling module for oneself and is connected with memory switch circuit module respectively, memory switch circuit module is connected with relay switch conversion module, relay switch conversion module meets domestic appliance. The utility model discloses has guaranteed the commercial power and has supplied power when the stand -by power source is different, at the mains failure and recover the back, automatic cutout with from being connected of stand -by power source, guaranteed safe in utilizationly.
Description
Technical field
The utility model relates to technical field of generators, particularly a kind of intelligent domestic electric switching circuit, when using for minitype gas dynamotor family and the safety switch changed of civil power.
Background technology
For ensureing the uninterrupted of household electricity, in the period that supply of electric power is very in short supply, general family all configures power autonomous, namely when power failure is powered in municipal administration, enables power autonomous for household electrical appliance.And be paroxysmal during municipal service restoration, unknown event, if under the state of power autonomous power supply, civil power restores electricity suddenly, and this is quite dangerous, gently then burns out electrical equipment, heavy then cause power supply fire.
Utility model content
In order to overcome the shortcoming of prior art, the utility model provides intelligent domestic electric switching circuit.
Technical solutions of the utility model are as follows:
Intelligent domestic electric switching circuit, comprise commercial power supply voltage sampling module and power autonomous voltage sampling module, described commercial power supply voltage sampling module is connected with relay switch modular converter respectively with power autonomous voltage sampling module, described commercial power supply voltage sampling module is connected with memory switch circuit module respectively with power autonomous voltage sampling module, described memory switch circuit module is connected with relay switch modular converter, and described relay switch modular converter connects household electrical appliance.
As preferably, described memory switch circuit module is made up of ratchet wheel relay.
The utility model beneficial effect is: under normal circumstances, relay switch modular converter and commercial power supply voltage sampling module generation closed-loop path, and relay switch modular converter and power autonomous voltage sampling module disconnect, and commercial power supply is to Household Appliance; When commercial power supply voltage sampling module has a power failure, power autonomous voltage sampling module starts, to memory switch circuit module pulse signal, memory switch circuit module makes the double-throw contact of relay switch modular converter, relay switch modular converter and power autonomous voltage sampling module generation closed-loop path, power autonomous voltage sampling module supplies household electrical appliance; During the module recovery of commercial power supply voltage sampling, to memory switch circuit module pulse signal, memory switch circuit module makes the double-throw contact again of relay switch modular converter, relay switch modular converter and commercial power supply voltage sampling module generation closed-loop path, relay switch modular converter and power autonomous voltage sampling module disconnect, commercial power supply supplies household electrical appliance, circulation like this, which ensure that civil power from power autonomous different time power, after mains failure also recovers, automatic cut-out and power autonomous connection, ensure that use safety.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the utility model structural representation.
Wherein: 1, commercial power supply voltage sampling module; 2, power autonomous voltage sampling module; 3, memory switch circuit module; 4, relay switch modular converter.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Consult Fig. 1.
Intelligent domestic electric switching circuit, comprise commercial power supply voltage sampling module 1 and power autonomous voltage sampling module 2, described commercial power supply voltage sampling module 1 is connected with relay switch modular converter 4 respectively with power autonomous voltage sampling module 2, described commercial power supply voltage sampling module 1 is connected with memory switch circuit module 3 respectively with power autonomous voltage sampling module 2, described memory switch circuit module 3 is connected with relay switch modular converter 4, and described relay switch modular converter 4 connects household electrical appliance.
Described memory switch circuit module is made up of ratchet wheel relay.
The utility model principle is, under normal circumstances, relay switch modular converter 4 and commercial power supply voltage sampling module 1 form closed-loop path, and relay switch modular converter 4 and power autonomous voltage sampling module 2 disconnect, and commercial power supply is to Household Appliance, when commercial power supply voltage sampling module 1 has a power failure, power autonomous voltage sampling module 2 starts, to memory switch circuit module pulse signal, memory switch circuit module 3 makes relay switch modular converter 4 double-throw contact, relay switch modular converter 4 and power autonomous voltage sampling module 2 form closed-loop path, and power autonomous voltage sampling module 2 supplies household electrical appliance, when commercial power supply voltage 1 sampling module recovers, to memory switch circuit module 3 one pulse signals, memory switch circuit module 3 makes relay switch modular converter 4 double-throw contact again, relay switch modular converter 4 and commercial power supply voltage sampling module 1 form closed-loop path, relay switch modular converter 4 and power autonomous voltage sampling module 2 disconnect, commercial power supply is to Household Appliance, circulation like this, which ensure that civil power from power autonomous different time power, after mains failure also recovers, automatic cut-out and power autonomous connection, ensure that use safety.
Above-mentioned drawings and Examples are only for illustration of the utility model, and any art those of ordinary skill to its suitable change done or modification, or is used other flower pattern instead and made this technical change, all should be considered as not departing from the utility model patent category.
