Abstract
The utility model discloses a loop control switching device of an electric appliance power switch. The device comprises an electric appliance. A power change-over switch is arranged on the electric appliance. The power change-over switch comprises: a at least two switching control locations for providing voltages of 110V and 120V respectively; a warning device which comprises a green indicating lamp and a red indicating lamp; and a power supply detecting device arranged inside the electric appliance. The power supply detecting device is electrically connected with the warning device; the power supply detecting device detects a real access voltage and compares the real access voltage with a switched voltage of the switching control locations of the power change-over switch; if the real access voltage matches the switched voltage, the line between the electric appliance and a power supply is conducted and the green indicating lamp is turned on; and if the real access voltage does not match the switched voltage, the line between the electric appliance and the power supply is cut off and the red indicating lamp is turned on.
Description
Technical field:
The utility model relates to a kind of circuit controls switching device shifter, refers in particular to a kind of circuit controls switching device shifter of appliance mains switch.
Background technology:
Due to the quick progress of science and technology, and economic fast development, so just there is increasing people to travel to countries in the world, and can habitually carry some easier compact electric apparatus articles for use the whilst on tour people, such as: electric saver etc.; Yet, because the voltage that various countries use often is not quite similar with own national voltage used, so when making electrical appliance in unwitting situation, usually cause the damage of these electric equipment products because of the difference of voltage.Be to adopt wide voltage to realize for fear of cause the damage of electric equipment products, prior art because of the difference of voltage, but cost is very high.And the loop apparatus of the appliance mains switch of commonly using at present, directly be switched to power supply electrical equipment on by supply socket through plug due to what just singly deposit, middle and none can for detect this voltage whether meet these electric equipment products voltage the time, just might cause because voltage does not meet the damage of these electric equipment products.
Be directed to this, so the applicant designs the utility model.
The utility model content:
The purpose of this utility model is to provide a kind of circuit controls switching device shifter of avoiding causing because voltage does not meet the appliance mains switch of electric equipment products damage.
the utility model realizes that the technical scheme that its purpose adopts is: the circuit controls switching device shifter of this appliance mains switch comprises an electrical equipment, one power change-over switch is installed on this electrical equipment, this power change-over switch comprises that at least two are cut controlled position, the controlled position of cutting of cutting controlled position and an energising 220V voltage of one energising 110V voltage, and be provided with an alarming device, this alarming device can be a green indicating lamp and a red led, one electric power detecting device is installed in this electrical equipment, this electric power detecting device and alarming device electrically connect, cut the voltage that controlled position switch to of the actual voltage ratio that enters of this electric power detecting device detecting to this power change-over switch, if both coincide the line of conducting electrical equipment and power supply, green indicating lamp will be the state that lights this moment, if both misfit, cut off the line of electrical equipment and power supply, red led will be the state that lights this moment.
Or, described power change-over switch cut controlled position be an energising ON cut controlled position and an energising OFF cut controlled position.
Furthermore, described red led and green indicating lamp are a LED lamp, show correct and error messages with this LED lamp bright light.
Or described alarming device is a display screens, and this display screens shows the error messages word.
Or described alarming device is loudspeaker, and these loudspeaker send the error messages caution sound.
Furthermore, described electrical equipment is fluorescent lamp.
The beneficial effects of the utility model are: 1, the electric power detecting device in the utility model can be detected power supply and whether meets the applied power supply of product, can not cause because of the power supply of mistake damage to reach this product of protection.2, cost of manufacture is low.
Description of drawings:
Fig. 1 is the circuit controls switching device shifter schematic diagram of appliance mains switch in the present embodiment.
Fig. 2 is the circuit controls switching device shifter cutaway view of appliance mains switch in the present embodiment.
Symbol description:
10 electrical equipment
11 power change-over switchs
