Abstract
The utility model discloses a multifunctional solar power charger circuit, which includes a solar panel, a lithium ion cell, a voltage booster circuit and various output interfaces; wherein, an output interface of the solar panel is connected with a charging interface of the lithium ion cell, and an output interface lithium ion cell is connected with the voltage booster circuit, and the voltage booster circuit is connected with the various output interfaces. In addition, the other charging interface of the lithium ion cell can be connected with a power supply adapter by a charging protection circuit. So the charger can utilize the solar power to charge for the lithium ion cell; the power supply adapter and the charging protective circuit can be utilized to charge for the lithium ion cell when the sunshine is unavailable. The charger is suitable for charging for the charged equipment such as a mobile phone, an MP3, an MP4, a digital camera, an interphone and so on; the utility model can also be arranged with a radio and have the illumination and note-checking function.
Description
Technical field
The utility model relates to a kind of charger circuit, particularly a kind of charger circuit that utilizes solar energy to give the battery electric power storage in the charger.
Background technology
At present, various portable digital products and multimedia handset cause proportional the reducing of volume needs of product internal battery, so the capacity of battery are also along with minimizings along with the volume requirement of product own is more and more littler.Meanwhile, along with portable set and multimedia handset display screen are increasing, function is more and more, and needed power consumption also further strengthens.Therefore when people go on business or be open-air, through regular meeting the situation of MP3, MP4 or mobile phone outage appears, so that cause communication inconvenience maybe can't use MP3, MP4 and other digital product.At present result of the above problems is to utilize a joint 1.5V alkaline dry battery utilization to rise circuit voltage is risen to the equipment required voltage of being recharged to charge.The main advantage of this charger is to buy conveniently, and it is convenient to change battery.Its weak point is:
1, can't buy in the open air under the situation of dry cell, can't use;
2,1.5V alkaline dry battery self capacity amount is not high, adds the transition loss that booster circuit is middle, and the time of use is shorter;
3, its output interface and output voltage are fixed, and can't satisfy the charging demand of dissimilar digital products;
4, often change the discarded battery in back and can cause certain pollution environment.
Summary of the invention
The purpose of this utility model is the deficiency that overcomes above-mentioned existing charger, provide a kind of solar energy that can utilize to the battery electric power storage in the charger, and possess the charger circuit of multiple output interface, thereby can charge for dissimilar equipment that is recharged such as mobile phone, MP3, MP4, digital camera, intercoms.
Another purpose of the present utility model is except that above-mentioned purpose, and a kind of charger circuit that can also carry out electric power storage by civil power to the battery in this charger is provided.
The 3rd purpose of the present utility model is except that above-mentioned second purpose, and a kind of charger circuit of subsidiary radio function is provided.
The 4th purpose of the present utility model is except that above-mentioned the 3rd purpose, and the charger circuit of the ultraviolet light that a kind of subsidiary illuminating LED lamp and currency examine use is provided.
More than the realization of first purpose, can adopt following technical scheme: the charger of this programme comprises solar panel, lithium ion battery, booster circuit and multiple output interface, wherein the output interface of solar panel is connected with the charging inlet of lithium ion battery, the output interface of lithium ion battery is connected with booster circuit, and booster circuit is connected with multiple output interface.
More than the realization of second purpose, can adopt following technical scheme: the charger of this programme is on the basis of such scheme, and another charging inlet of said lithium ion battery is connected with a power supply adaptor by charge protector.
More than the realization of the 3rd purpose, can adopt following technical scheme: the charger of this programme is on the basis of above-mentioned second technical scheme, is parallel with a receiver circuit in the input of said booster circuit.
More than the realization of the 4th purpose, can adopt following technical scheme: the charger of this programme is on the basis of above-mentioned the 3rd technical scheme, also is connected with the ultraviolet light that currency examine is used with illuminating LED lamp respectively in the output interface of said lithium ion battery.
The beneficial effects of the utility model are:
1, for the charger circuit of first kind of technical scheme, it can carry out the dry cell that electric power storage has avoided using contaminated environment to wherein lithium ion battery by the sun.In addition, because it has multiple output interface, therefore can charge for multiple equipment that is recharged such as mobile phone, MP3, MP4, digital camera, intercoms.And lithium ion battery is bigger than the capacity of dry cell, so the service time of digital product can be longer.
2, for the charger circuit of second kind of technical scheme,,, can also utilize civil power to give lithium ion cell charging so do not having under the situation of sunlight because it has increased power supply adaptor and charge protector.Charge protector has been avoided the generation of overcharging, and has prolonged lithium ion battery useful life.
3, for the charger circuit of the third technical scheme, because it has increased receiver circuit, so the user can also appreciate the program in broadcasting station except that can be used in charging.
4, for the charger of the 4th kind of technical scheme, because it has increased the ultraviolet light that illuminating LED lamp and currency examine are used, so this charger circuit can also be used to illumination or check counterfeit money.
In order to make the utility model more clear, it is described further below by drawings and Examples.
