The intelligent charger is simple in structure, high in compatibility, and convenient in use.
Description
Technical field
The utility model relates to appliance field, particularly a kind of intelligent charger.
Background technology
Now, lithium battery occupies center of gravity because in light weight, the good low price of conductivity and little with impact to the harm of environment has obtained good development at battery industry, has been widely used on the various mobile devices.Under charged state, if the charging voltage of lithium battery repeats to surpass the state more than 4.3 volts, have smolder, the danger of on fire even blast.Be lower than as the voltage of lithium battery under 2.0 volts the state and place for a long time, then lithium battery can't re-use or charge.Overcharge or when discharging (use), accident even blast that life-span that may the contracting lithium battery or take place can not expect, therefore, there is defective in prior art, needs to improve.
The utility model content
The technical problems to be solved in the utility model provides a kind of simple in structure, compatible strong, intelligent charger easy to use for overcoming weak point of the prior art.
For solving technical problem of the present utility model, the technical scheme that adopts is: a kind of intelligent charger, comprise input port, electric pressure converter, the pressure-stabilizing constant flow controller, output port, control part, described input port is connected with electric pressure converter, described electric pressure converter and pressure-stabilizing constant flow controller interconnect, described pressure-stabilizing constant flow controller is connected with output port, described control part is provided with current detector, the instruction chip, described current detector is connected with output port, described current detector and instruction chip connects, and described instruction chip is connected in input port;
Described output port is USB port.
Beneficial effect with respect to prior art is, the power supply signal that the electric pressure converter basis provides, and outwards power after being converted into the pressure-stabilizing constant flow signal with predeterminated voltage value, the convenience that charger uses improved widely, current detector is set, detect lithium battery saturated after, disconnect charging circuit by the instruction chip, stop charging, avoid overcharging, the no-voltage phenomenon occurs, prolong power consumption equipment battery useful life, reduced user's cost.
Description of drawings
Fig. 1 is framework map of the present utility model.
Embodiment
Below in conjunction with accompanying drawing optimal way of the present utility model is described in further detail.
As shown in Figure 1, this intelligent charger is simple in structure, compatible strong, easy to use.This intelligent charger, comprise input port 5, electric pressure converter 2, pressure-stabilizing constant flow controller 3, output port 4, control part, described input port 5 is connected with electric pressure converter 2, described electric pressure converter 2 interconnects with pressure-stabilizing constant flow controller 3, described pressure-stabilizing constant flow controller 3 is connected with output port 4, described control part is provided with current detector 6, instruction chip 1, described current detector 6 is connected with output port 4, described current detector 6 and instruction chips 1 connect, and described instruction chip 1 is connected in input port 5; Described output port is USB port.
First power supply signal that described electric pressure converter imports input port into changes the second source signal with a magnitude of voltage of presetting into, described pressure-stabilizing constant flow controller is used for stablizing described second source voltage of signals and electric current, and described output port outwards provides the signal of the second source with burning voltage and electric current; In outside power supply, current detector detects the size of current of output port, when detect electric current less than or when being lower than its preset value, transmit signal to described instruction chip, described instruction chip disconnects charging circuit at once, avoids overcharging; When detecting internal current instability or equipment fault, described instruction chip disconnects charging circuit at once, avoids causing the device interior short circuit, so that causes danger.
Obviously, those skilled in the art can carry out various changes and modification to the utility model and not break away from spirit and scope of the present utility model.Like this, if of the present utility model these are revised and modification belongs within the scope of the utility model claim and equivalent technologies thereof, then the utility model also is intended to comprise these changes and modification interior.
