Abstract
The utility model relates to a pictographic power supply device which comprises a shell (2), a pressure reducing circuit element (6) arranged in the pictographic power supply device and a rectifier (7). The utility model is characterized in that the shape of the shell (2) is like a battery, and a capacitor adopted in the pressure reducing circuit is nonpolarity monolithic capacitor with small volume and large capacity. The utility model has the advantages of simple structure, easy production, low cost, low use cost and convenient portability. The pictographic power supply device is used for replacing a plurality of batteries in an electric appliance and frequent change or charge can not be required.
Description
The utility model relates to a kind of supply unit.
The electrical equipment of more existing use batteries is shaver for example, because its battery needs often to change, its usage charges are very high.If the employing rechargeable battery is also convenient inadequately again because charging needs equipment and time, and usage charges are still very high.
The purpose of this utility model is to provide a kind of Pictographic power supply device that replaces battery, and it can remedy the deficiency of existing apparatus.
The utility model has a shell, and reduction voltage circuit and rectifying device wherein are housed, and the shape that it is characterized in that described shell is as battery, and the electric capacity in the described reduction voltage circuit adopts the non-polar leaded multilayer ceramic capacitor of the big capacity of small size.
The utility model is simple in structure, makes easily, and cost is low, replaces battery in some electrical equipment with it, need not often change or charge, and directly injects AC power and can use, and usage charges are very low to be easy to carry again.
Further specify the utility model below in conjunction with embodiment and accompanying drawing.
Accompanying drawing 1 is a contour structures schematic diagram of the present utility model.
Accompanying drawing 2 is its internal structure schematic diagram.
Accompanying drawing 3 is its circuit diagram.
Shell of the present utility model (2) is as two batteries, and it has lid to open, and the one end has positive pole (4) and negative pole (5), and a circular hole (3) is arranged above, and plug (1) exposes outside shell (2).The interior right-hand member of shell (2) is equipped with reduction voltage circuit device (6), wherein used capacitor C 1 is the jumbo leaded multilayer ceramic capacitor of small size, next be rectification circuit (7) and display circuit (8), the latter's light-emitting diode faces the circular hole (3) on the shell (2), is a filter circuit (9) toward the left side again.Like this, during use attaching plug (1) is inserted on the 220V AC power, alternating current is added in suitable direct voltage on positive pole (4) and the negative pole (5) through step-down, rectification, filtering and process protective resistance (10).Its both positive and negative polarity contact is identical with battery location.This Pictographic power supply adopts little shape electronic component to make occupation space can be very little.It can with the battery dual-purpose, just use it when power supply is arranged, use battery during non-transformer instead, its magnitude of voltage, current value and shell shape and greatly I decide according to the situation of the used battery of electrical equipment, operating current can reach the 500mA(milliampere).
Claims (1)
1, a kind of Pictographic power supply device, it has shell (2), in reduction voltage circuit device (6) and rectifying device (7) are housed, the shape that it is characterized in that described shell (2) is as battery, the electric capacity that adopts in the described reduction voltage circuit is the non-polar leaded multilayer ceramic capacitor of the big capacity of small size.
