Description

A kind of control electrical appliance is charging device successively

Technical field

The utility model relates to charger field, particularly a kind of control electrical appliance charging device successively.

Background technology

Development along with electronic product, increasing electrical appliance gos deep into each details of our life, charge prepd is more and more, but the gross power of factory, family, dormitory is often limited, and need now the product of charging more and more, and mobile phone, panel computer etc., need frequency and the number of times of charging more and more, if once a plurality of electronic products charge simultaneously, be easy to cause danger, any being inserted on socket after if the electronic product charging is completed, not only can cause safety problem, and power consumption is larger, can consumes a large amount of electric energy.

The utility model content

For above problem; The utility model is by a kind of control electrical appliance of design charging device successively; This device can charge to a plurality of electronic products successively; Thereby can greatly reduce unnecessary energy consumption; Reducing unnecessary safety problem occurs; The utility model provides a kind of control electrical appliance charging device successively; Comprise interface circuit; Decoder; Single-chip microcomputer; Resistor group; Crystal oscillator and control switch; Described control switch comprises red signal control switch and green light signals control switch; Described red signal control switch one end ground connection; The red signal control switch other end enables control end with single-chip microcomputer and is connected; Described green light signals control switch one end ground connection; The described green light signals control switch other end is connected with single-chip microcomputer RD end; Described crystal oscillator is connected with the X2 port with single-chip microcomputer X1; Described decoder signal receiving end is connected with single-chip microcomputer; Described decoder signal output part is connected with interface circuit; Described interface circuit has 3-8; Each interface circuit connects a decoder signal output part port; The corresponding resistance of described each interface circuit; Described resistance forms resistor group; Described resistor group is between decoder and single-chip microcomputer; Resistor group is connected with single-chip microcomputer with decoder.

As further improvement of the utility model, described decoder is the 74L138 type, and the main model of the utility model decoder can be used 74L138 type decoder after tested.

The utility model is a kind of control electrical appliance charging device successively; This device uses single-chip microcomputer to switch on to each interface successively according to the electronic product situation by Single-chip Controlling; And other interface no powers are realized each to an interface charging; Like this after an electronic product charging is completed; Switching at once another electronic product charges; Thereby can charge to a plurality of electronic products successively; Therefore can not burn out because a plurality of electronic products charge simultaneously fuse and then cause safety problem; Can not keep charged state to cause a large amount of energy consumptions after completing because of the charging of electronic equipment always yet.
