Description
The utility model belongs to the household appliances field, refers in particular in a kind of process of quick charge, can be accurately and apace reaction temperature variation and change current charges or trickle charge into, and have the device of great heat radiation effect.
Based on the consideration of environmental protection, present green group encourages the people to use rechargeable battery energetically, cause environmental pollution to avoid battery after discarded, and rechargeable battery must utilize charger to charge.
Conventional charger construction is formed housing by a base and a loam cake, and is provided with circuit board in housing, is laid with charging circuit, circuit for detecting and constant-current circuit on this circuit board, and is provided with a plurality of cathode conductive films and cathode conductive film in this charging circuit.Be covered with a plurality of battery accommodating groove on being somebody's turn to do, and the opposite end of this battery accommodating groove is respectively equipped with slotted eye, when making this loam cake be matched with this base, make above-mentioned positive and negative electrode conducting strip pass this slotted eye and lay respectively at relative two ends of this battery accommodating groove, thereby, in the time of in rechargeable battery is positioned over this battery accommodating groove, be contacted with this positive and negative electrode conducting strip respectively by is allowed the positive and negative electrode of rechargeable battery and charged.
General charger all can produce heat in charging process, if the heat temperature that is produced may influence the working curve of battery when too high, even damage battery.Therefore, the charging circuit of conventional charger all is designed to charge with low current, but needs the long time with trickle charge constantly, and charge efficiency is relatively poor.Thereby, the charger that had the quick charge effect afterwards is the thermistor and general resistance that is provided with series connection at charging circuit, circuit between this thermistor and the general resistance is equipped with a transistor as the diverter switch use, it intercepts a normal temperature by this thermistor, and make battery in being lower than this normal temperature scope, carry out large current charge, then do the comparison of a voltage between thermistor and the general resistance, make battery when the temperature of charging process reaches the set point of this comparative voltage, make transistor action and switch to low current and charge, temperature when avoiding charging is too high and guarantee the working curve of battery, and uses and shorten the charging interval to improve charge efficiency.
Yet, have certain distance between above-mentioned traditional thermistor and the battery, and battery is in the space that is passed between thermistor and battery at the heat that charging the time is produced, detect temperature in this space by this thermistor again.Therefore, the temperature that thermistor is sensed not is the actual temperature of battery itself, but has portion temperature to be dissipated in the air, exists the problem that influences charge efficiency so the temperature of battery itself is still possible too high.In addition, the heat that traditional rechargeable battery produced all is to allow it dissipate to naturally in the air, so if the ventilation of charger place environment is worse, so the heat that is produced promptly can't successfully be discharged outside the housing, this also is another reason that influences charge efficiency.
The purpose of this utility model is to propose a kind of quick charger of being made up of base, loam cake, battery cover and fan assembly, it can not only carry out quick charge, and can effectively get rid of the charger shell body heat content, avoid influencing its charge efficiency, thereby solved the existing in prior technology problem.
The technical scheme that the utility model adopted is that it includes a base, one loam cake and a battery cover, this base is provided with circuit board, be laid with charging circuit on this circuit, testing circuit and constant-current circuit, and on this circuit board, be provided with a plurality of cathode conductive films and cathode conductive film, be covered with a plurality of battery accommodating groove on being somebody's turn to do, and when this loam cake is matched with this base, make just above-mentioned, cathode conductive film lays respectively at relative two ends of this battery accommodating groove, this charging circuit is provided with the thermistor and general resistance that is series connection, circuit between this thermistor and the general resistance is equipped with a transistor, intercept a normal temperature by this thermistor, and make battery in being lower than the scope of this normal temperature, carry out large current charge, then do the comparison of a voltage between thermistor and the general resistance, make battery when the temperature of charging process reaches the set point of this comparative voltage, make transistor action and switch to low current and charge, it is characterized in that said thermistor is coated with the heat conduction patch, and said battery accommodating groove is provided with a hole at least, and makes said heat conduction patch expose this hole and can allow battery touch this heat conduction patch.
Wherein said base is provided with fan assembly, and is covered with a plurality of louvres on said, starts the running of this fan assembly simultaneously and the heat in the interior space that base and loam cake enclosed is discharged by louvre in charging process.
Advantage of the present utility model is that the thermistor of charging circuit directly contacts battery body, and the heat that makes battery be produced in charging process can accurately be detected by thermistor, and then high electric current is changed on fast reaction ground or low current charges; In addition, because charger inside is provided with fan assembly, and is provided with a plurality of heat radiation slotted eyes above the housing of charger, make that the heat that is produced in the charging process can be drained into outside the housing fast and effectively, in order to avoid influence charge efficiency.
