Description
Technical field
The utility model relates to the guard technology field of household electrical appliance, relates in particular to when the user does not use power supply to be the device of the automatic outage of household electrical appliance.
Background technology
Along with socioeconomic continuous development, people's material and cultural needs is vigorous day by day, and nowadays, various household electrical appliance such as refrigerator, washing machine, microwave oven, TV, computer etc. have been arranged in the middle of ordinary people's the family.Bring the while greatly easily of life to us at these electrical equipment, because the bad custom of people also can be given oneself to live and be brought the factor of a lot of danger, for example, single container washing and extracting machine can be closed the power supply of washing machine automatically after laundry finishes, teleview and use the dynamo-electric source of remote controller closing television after finishing, microwave oven can cut off the power supply of microwave oven automatically after heat food, computer can cut off power supply of computer or the like after one-touch closing, though these electrical equipment have all cut off the electrical equipment its own power source automatically, but the power line of these electrical equipment also is connected the city with on the power line, just because of not pulling out attaching plug, not only can be impacted the useful life of electrical equipment, tend to cause the spontaneous combustion of electrical equipment and cause fire.
The utility model content
The purpose of this utility model provides a kind of when the user does not make electrical appliance, can cut off the device of mains-supplied circuit automatically, guarantees the safety that electrical equipment uses.
The purpose of this utility model is achieved through the following technical solutions:
A kind of auto-power-off device comprises central controller 11, digital current meter 12, electric-controlled switch 13, hand switch 14, and described digital current meter 12, electric-controlled switch 13, hand switch 14 are connected with central controller 11 respectively; Digital current meter 12 is installed in the indoor supply line, is used to implement to monitor the current data of supply line, and current data is delivered to central controller 11; When supply line when current value is lower than a current value of setting within the predetermined time, or voltage is when surpassing the normal voltage some, and central controller 11 control electric-controlled switchs 13 cut off supply lines; In the time of the closed electric-controlled switch of needs 13, press hand switch 14, trigger central controller 11, the 13 closed conductings of central controller 11 control electric-controlled switchs.
Concrete, described auto-power-off device also comprises indicating device 15, described indicating device 15 is connected with central controller 11; Indicating device 15 comprises light-emitting diode, LCD MODULE.
Concrete, described central controller 11 comprises single-chip microcomputer, ARM, DSP, special-purpose control integrated circuit.
Concrete, described electric-controlled switch 13 is a kind of switches that can pass through the voltage control automatic open close, accept the control of central controller 11.
Concrete, described hand switch 14 comprises key switch, soft-touch control, remote control switch.
Description of drawings
The utility model will illustrate by example and with reference to the mode of accompanying drawing, wherein:
Fig. 1 is the schematic diagram of the utility model auto-power-off device.

Disclosed arbitrary feature in this specification (comprising any accessory claim, summary and accompanying drawing) is unless special narration all can be replaced by other equivalences or the alternative features with similar purpose.That is, unless special narration, each feature is an example in a series of equivalences or the similar characteristics.
The utility model is described in more detail below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of auto-power-off device comprises central controller 11, digital current meter 12, electric-controlled switch 13, hand switch 14, and described digital current meter 12, electric-controlled switch 13, hand switch 14 are connected with central controller 11 respectively; Digital current meter 12 is installed in the indoor supply line, is used to implement to monitor the current data of supply line, and current data is delivered to central controller 11; Described electric-controlled switch 14 is installed in the supply line, is used for disconnecting or closed supply line under the control of central controller 11.
When the electric current I of supply line less than a certain setting threshold I
s, and continue to surpass scheduled time t
sThe time central controller 11 control electric-controlled switchs 13 cut off supply lines; In the time of the closed electric-controlled switch of needs 13, press hand switch 14, trigger central controller 11, the 13 closed conductings of central controller 11 control electric-controlled switchs.
Concrete, described auto-power-off device also comprises indicating device 15, described indicating device 15 is connected with central controller 11.
Concrete, described central controller 11 is realized the purpose of central controller by comprising modes such as single-chip microcomputer, ARM, DSP, special-purpose control integrated circuit.
Concrete, described electric-controlled switch 13 is a kind of switches that can pass through the voltage control automatic open close, this control switch can be finished the closure of switch automatically under the control of control signal; Electric-controlled switch 13 is accepted the control of central controller 11.
Concrete, described indicating device 15 comprises light-emitting diode, LCD MODULE; Can adopt the light on and off of light-emitting diode to represent the closure and the disconnection of electric-controlled switch 13; Also a little LCD MODULE be can pass through, the closure and the disconnection of electric-controlled switch shown more intuitively.In order to save cost, indicator light 15 of the present utility model adopts the technical scheme of light-emitting diode.
Concrete, described hand switch 14 comprises key switch, soft-touch control, remote control switch.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection range of the present utility model.
