Embodiment

Shown in Fig. 1-2, a kind of battery described in the utility model with network supply, comprise that the outside is provided with the main battery 1 of plastic casing, the inside of main battery 1 is provided with function wiring board 7, the two ends up and down of function wiring board 7 are connected with main battery negative electrode 3 with main battery positive electrode 2 respectively, one side of function wiring board 7 is provided with output indicator 6, one side at the middle part of function wiring board 7 is provided with voltage-selected switch 5, voltage-selected switch 5 is electrically connected with function wiring board 7, the bottom of function wiring board 7 connects attaching plug 4 by external cord, main battery 1 use of can connecting with secondary cell, the outside of described secondary cell also is provided with plastic casing, the inside of described secondary cell is provided with connection wire 8, and the two ends of connection wire 8 are connected with secondary cell negative electrode 10 with secondary cell positive electrode 9 respectively.

In Fig. 1, the main battery interior arrangement has functional line road plate 7, promptly 220 volts power network AC power is converted to direct voltage, when attaching plug 4 is inserted the electrical network socket, main battery positive electrode 2 and main battery negative electrode 3 just have direct voltage output, simultaneously output indicator 6 lights, if regulate the output voltage height, can stir voltage-selected switch 5 and get to the required voltage shelves and get final product; Voltage can be selected by toggle switch, there are 1.5 volts, 3.0 volts, 4.5 volts, 6.0 volts fourth gear outputs optional, in Fig. 2, secondary cell is that battery is used in the series connection of main battery, when will using two joints above during to four batteries, can be the use of entering of secondary cell string, secondary cell inside has only a connection wire 8, only as the circuit turn-on power loss, itself does not provide supply voltage.

When single-unit uses battery, only need be much of that once the joint main battery, output is selected to beat on 1.5 volts, can use.When wanting two joints to use battery,, the voltage of main battery is chosen in 3.0 volts goes up just passable with main battery series connection one joint secondary cell.Same, when wanting three joint use batteries,, main battery voltage is chosen on 4.5 volts with main battery string two joint secondary cells, when wanting four joints to use battery,, the power supply of main battery is chosen in 6.0 volts upward gets final product with main battery string three joint secondary cells.If use 12 volts or when being lower than 12 volts of voltages, and available two joint main batterys, the string secondary cell, and select main battery power range to suitable gear can reach all electric pressures.The rest may be inferred, and the main battery ceiling voltage is 6.0 volts.Can reach the purpose of different voltages of output or different current classes by series and parallel, very convenient.

Be illustrated in figure 3 as the circuit theory diagrams of main battery, when the AC220V input has electricity, alternating current one end enters into the bridge rectifier circuit of being made up of D1-D4 through R1 resistance, the voltage that becomes the about 250V of direct current after rectification is stored in the C1 capacitor, positive voltage is transported to the L1 winding of T1, pass to the collector electrode of Q1, other end positive voltage is transported to the base stage that passes to Q1 behind the R2 resistance, the Q1 base stage obtains bias current, reach negative electrode through emitter to R5 and constitute the loop, because of Q1 has amplification, Q1 conducting L1 has electric current to pass through, because of L1 and L2, L3 belongs to 1 high frequency transformer T1 together, the electric current of L1, at L2, also induced electric current output among the L3, in L2, induce reverse electric current, it is the electric current of inverse-excitation type direction, this electric current passes through C3, R4 acts on the base stage of Q1, weakens the base current of Q1, and Q1 ends, after Q1 ends, the L1 current vanishes, the backward current of same L2 has not had yet, and Q1 not only under the effect of R2 bias voltage but also the beginning conducting, enters another turning on and off of taking turns, so auto-excitation type is repeatedly vibrated, and produces the high-frequency alternating current of about 200 kilo hertzs of sesames.For preventing that Q1 from causing the excessive possibility that burns out of electric current because of factors such as temperature, incorporated clamping transistor Q2 in the base stage of Q1, just the emitter voltage of Q1 can not be higher than 1.4V, if be higher than 1.4V, the Q2 conducting is lower than 1V to the base potential of Q1 limit, Q1 is limit, remain on constant current state, i.e. 1.4V ÷ 10 Ω=0.14A, the collector current of Q1 can not exceed 0.14A.For keeping the stability of output voltage, the rectification circuit of D8, C4 and the voltage stabilizing didoe of D7 have been incorporated at the two ends of L2, make the current potential of L2 remain on higher position in voltage of voltage regulation, same, because of L2 and L3 are the same number of turn windings of same high frequency transformer, be equal to the voltage of L2 at the voltage of L3 output.

Output voltage is after the L3 induction exports the D9 high-frequency rectification to, C5 filtering, R6, D10 export indication, again by output voltage selector switch K1 output or by diode decompression output, C6 is filtering again, and R7 exports 6V, 4.5V, the required direct voltage of 3V, 1.5V after incorporating parallel resistance into.

Battery overall volume with network supply described in the utility model is the same with general dry battery, big trumpet is also arranged, in the time will making electrical appliance, the battery of this practicality invention is packed in the electrical equipment, the power line of battery is inserted electrical network socket (220V, 50Hz) power supply, electrical appliance can have been made, and voltage is arbitrarily optional, installs and uses very convenient.
