Abstract
The utility model discloses a lithium battery voltage reducing device in the field of household electrical appliances. In the process of replacing a high-pollution disposable common battery with a lithium battery, a rated voltage of the single lithium battery is 3.7V, thus the requirement that a common rated voltage of the common household electrical appliance is 3V can not be satisfied, in order to solve the deficiency of the prior art, a lithium battery voltage regulator of the utility model is connected in series with the single lithium battery for use, so that an output voltage drops from 3.7V to 3V, thereby meeting the requirement that the rated voltage of the household electrical appliance is 3V. The lithium battery voltage regulator of the utility model has the advantages of simple circuit, low cost, simple and convenient use, energy saving, environmental protection, and so on, thereby laying a foundation for gradually replacing the high-pollution battery in future.
Description
Technical field
The utility model relates to a kind of voltage regulation of electric power sources device, and more particularly, the utility model relates to a kind of 3.7V lithium battery dropping equipment.
Background technology
The battery of at present household electrical appliance use mostly is greatly disposable carbon zinc dry cell, discarded battery can cause great pollution to environment, relatively pollute low repeatedly used Ni-MH battery, because the limitation of its material and production technology, its single-unit rated voltage can only reach 1.2 volts, and present employed household electrical appliance rated voltage is pressed 1.5 volts multiple level design mostly, some household electrical appliances causes brownout because of 1.2 volts the Ni-MH battery of packing into, and can't work, the lithium battery that substitutes common batteries has superior performance, environmental protection, no matter produce, use and scrap, do not contain, do not produce any lead yet, mercury, poisonous and harmful heavy metallic element and the materials such as cadmium, but because its single-unit rated voltage too high (3.7V), and make its use have certain limitation.
Summary of the invention
The purpose of the present utility model is for overcoming the deficiencies in the prior art, and a kind of and matching used lithium battery voltage regulator of lithium battery that proposes, after common 3.7V lithium battery is connected, allow the step-down of original 3.7V lithium battery be the 3V lithium battery, be general versatility battery.
The purpose of the present utility model is achieved through the following technical solutions:
A kind of lithium battery voltage regulator is characterized in that: it is comprised of shell and built-in 0.7V voltage drop element, and described shell is identical with carbon zinc battery, and described built-in 0.7V voltage drop element is connected with shell by wire.The utility model is on the basis that does not change former lithium battery, lithium battery voltage regulator of external series connection, lithium battery voltage regulator profile is identical with carbon zinc battery, realize the use of normal household electrical appliance two batteries or 4 batteries. in use, two batteries in this way, then can use a joint lithium battery and a joint lithium battery voltage regulator, identical with the occupation mode of normal family expenses two batteries, thus solved the civil nature of 3.7V lithium battery.
Technique scheme is done further to limit, and described 0.7V voltage drop element is a rectifier diode, and the positive pole of rectifier diode connects the negative pole of shell, and the negative pole of rectifier diode connects the positive pole of shell.This programme adopts rectifier diode as voltage drop element, is because the electric inherent characteristic conduction voltage drop of rectifier diode is 0.7 volt.
Technique scheme is done further to limit, and shell shape is identical with the 5# carbon zinc battery, or shell shape is identical with the 7# carbon zinc battery, and 5# or 7# battery are present household electrical appliances battery sizes commonly used.Below in conjunction with accompanying drawing essentiality content of the present utility model is described in further detail:
This lithium battery voltage regulator is comprised of shell and built-in 0.7V voltage drop element; shell is identical with 5# or 7# battery external form commonly used at present; built-in 0.7V voltage drop element is comprised of rectifier diode; the rectifier diode model adopts IN4001; the negative pole of rectifier diode connects the anode of shell; the positive pole of rectifier diode connects the negative terminal of shell; 0.7V it is 0.7 volt electrical characteristic that voltage drop element utilizes the intrinsic conduction voltage drop of rectifier diode; make the lithium battery voltage regulation utensil that the function of 0.7 volt of constant step-down be arranged; by being that 3.7 volts lithium battery is connected in series use with rated voltage; can export 3 volts of required voltages of household electrical appliance, built-in 0.7V voltage drop element also has the anti-loaded defencive function of battery polar.Compared with prior art, the utlity model has following beneficial effect:
1. it is simple and practical, with low cost that this lithium battery voltage regulator has circuit;
2. easy to use succinct;
3. energy-conserving and environment-protective.
Description of drawings
Fig. 1 is lithium battery voltage regulator schematic diagram.
Among the figure: rectifier diode 1, shell 2.
Specific embodiment
1 by 5# commonly used at present or 7# battery external form making lithium battery voltage regulator shell 2.
2 voltage regulator 0.7V voltage drop elements are comprised of rectifier diode 1, and rectifier diode adopts IN4001.
The negative pole of 3 rectifier diodes 1 connects the positive pole of shell 2, and the positive pole of rectifier diode 1 connects the negative pole of shell 2.
4 support the use with lithium battery when using, and connected mode is for connecting.
