Abstract
The utility model relates to a device for lighting and charging a mobile phone, which comprises a power supply part, wherein the power supply part outputs a low voltage after voltage is reduced by a switch pulse circuit, the low voltage is supplied to a special charge integrated circuit after rectified and then an energy storage chamber is charged. Meanwhile, a mobile phone can also be charged after a mobile phone charge switch is switched on. The energy storage chamber can charge the mobile phone when the 220V voltage is not available outdoors. Furthermore, the device can also be used for lighting. The utility model has the advantages of simple structure, easy fabrication, low cost, reliable operation and long service life and is a product frequently used in work and life.
Description
A kind of cell-phone charging is used two-in-one device with illumination, can be used for cell-phone charging, also can be used for illumination, is a kind of convenient and practical routine work, daily necessities.
The present charger for mobile phone that uses all is to plug charger for mobile phone to cell-phone charging under the situation that 220 volts of civil powers are arranged.Civil power is left in existence can not be to the shortcoming of cell-phone charging.Then there is the deficiency of function singleness in existing electric consumption on lighting tube.
The purpose of this utility model is to provide a kind of cell-phone charging and illumination two-in-one device, this device contains an accumulation chamber, can at any time mobile phone be charged under the civil power situation not having, this device utilizes the electric energy of accumulation chamber that illumination functions can also be provided simultaneously.
The purpose of this utility model is achieved through the following technical solutions, described cell-phone charging comprises power unit with illumination with two-in-one device, the power unit of described device connects the switching pulse circuit, output is 8.2 volts behind reduction voltage circuit, connect the charging special circuit after connecing rectification circuit again, connect energy storage section behind the described charging special circuit, described energy storage section is connected to S, S
1Two switches.Described device comprises mobile phone charging interface 4, illumination section 2, accumulation chamber 3, attaching plug 1.Described S switch is the cell-phone charging switch, S
1Switch is a lighting switch.Described charging special circuit comprises IC
1Circuit, its circuit model can be MC 34063 circuit.In this device, LED
1Be charging indicator light, LED
2Be power supply indicator, LED
3Be high brightness LED.In this device, accumulation chamber (3) is equipped with chargeable battery, and described battery is nickel-based battery or lithium battery etc.When emergent, can use disposable battery, for example four joint " AAA " commercially available batteries.
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a front view of the present utility model.
Fig. 2 is an end view of the present utility model.
Fig. 3 is a circuit working schematic diagram of the present utility model.
From Fig. 1, Fig. 2, can see the disclosed mechanical construction drawing of front view of the present utility model and end view.In Fig. 1,1 is 220 volts of attaching plugs, and 2 is illumination section, and 3 is accumulation chamber, and 4 is mobile phone charging interface.Fig. 3 is a circuit working schematic diagram of the present utility model.Disclose concrete circuit structure among the figure, operation principle is as follows: 220 volts of civil powers are exported 8.2 volts low-voltage after the step-down of switching pulse circuit, supply with the charging application-specific integrated circuit after rectification, to the accumulation chamber charging, open switch S and can charge simultaneously to mobile phone.Do not have when going out
Open switch S during 220 volts of civil powers, the accumulation chamber battery can be to cell-phone charging.When using up as the electricity of battery, interim emergent use of available commercially available " AAA " battery four joints.Open S when needing illumination
1Switch gets final product.
The utility model is simple in structure, and is easy to manufacture, and cost is low, reliable operation, and the life-span is long, is a kind of reliability and durability product.
