The specific embodiment
For making the object, technical solutions and advantages of the present invention clearer, below embodiment of the present invention is described further in detail.
For canteen is carried out to low-temperature heat, provide and continue insulation, the embodiment of the present invention provides a kind of warm-keeping device of canteen, referring to Fig. 1 and Fig. 2, described below:
The warm-keeping device of this canteen comprises: heated base 5, on heated base 5, be provided with adjustable connecting band 6, in heated base 5, be provided with: USB mouth 4, USB mouth 4 connects external power source, external power source inputs to the first resistance R 1, the first LED 1 and capacitor C 1, the first resistance R 1 connects the emitter stage of transistor T 1, and the colelctor electrode of transistor T 1 charges to Ni-MH battery 7 by isolating diode D1; The base stage of transistor T 1 connects the second resistance R 2; The negative electrode of isolating diode D1 connects electrothermal film 1 by switch 3, and electrothermal film 1 connects negative pole, the second resistance R 2 and the capacitor C 1 of Ni-MH battery 7 successively by the second LED 2.
It is current-limiting resistance that the first LED 1 and the second LED 2 have formed LED lamp 2, the first resistance R 1.Ni-MH battery 7 is connected with electrothermal film 1, and electrothermal film 1 is supplied to electrical heating.
During practical application, adopt USB interface 4 access direct current 5V power supplys to power to whole warming transposition, give Ni-MH battery 7 chargings, turn on-switch 3 makes its heating canteen can to electrothermal film 1 power supply simultaneously.Stop after 4 power supplies of USB mouth, turn on-switch 3, Ni-MH battery 7 directly gives electrothermal film 1 power supply, provides and continues the object that temperature reaches low-temperature heat.
The operation principle of this device of labor below: USB is inserted to the USB mouth 4 of switching power supply, now USB 1., the 4. output voltage of have+5V of pin, this voltage is delivered to the emitter stage of transistor T 1 by current-limiting resistance R1.Transistor T 1 is positive-negative-positive pipe, and it and peripheral interlock circuit form constant-current source, and the colelctor electrode of transistor T 1 charges to ni-mh electric current (+2.4V) by isolating diode D1 is logical.The second resistance R 2 in circuit and the first LED 1 are for crystal T1 pipe provides fixing bias current, and making constant-current source is 50mA to the charging current of Ni-MH battery 7.In circuit, capacitor C 1 can suppress the high fdrequency component of USB mouth 4 output voltages, plays current filtering effect.When not charging, diode D1 plays buffer action, prevents that cell voltage is added on transistor T 1.
At the bottom of heated base 5 is arranged on to canteen, fixing by adjustable connecting band 6, to connect after circuit, Ni-MH battery 7 makes interior electrothermal film 1 heating of heated base 5 as power supply, by liquid in contact and conduction heating container, plays heating and insulation effect.
During practical application, the electric current of USB mouth 4 outputs can reach 100mA.The Ni-MH battery 7 is here be total to+2.4V of two joints (7#) series connection.
The embodiment of the present invention to the model of each device except do specified otherwise, the model of other devices does not limit, as long as can complete the device of above-mentioned functions, all can.
It will be appreciated by those skilled in the art that accompanying drawing is the schematic diagram of a preferred embodiment, the invention described above embodiment sequence number, just to describing, does not represent the quality of embodiment.
The foregoing is only preferred embodiment of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
