Accompanying drawing explanation
Fig. 1 is a kind of new electrically heating heat-preservation lunch box schematic diagram.
Fig. 2 is a kind of new electrically heating heat-preservation lunch box vertical section front elevational schematic.
Detailed description of the invention
Below in conjunction with accompanying drawing, a kind of new electrically heating heat-preservation lunch box of the utility model is described further.
In Fig. 1,2,1-lid, 2-detachably container, 3-metallic plate, 4-USB interface, 5-clockwork spring handle, 6-trigger switch, 7-clockwork spring, 8-metal bar, 9-oval sheet metal, 10-magnet plate, 11-magnet, 12-helical girth sheets, 13-solenoid, 14-battery.
Electric heating cutlery box entirety, in cylindric, is mainly divided into four parts: outside, splendid attire food and heat generating parts, reserve battery 14 circuit part and battery 14 charging device.
External overall adopts the heat proof material that intensity is higher, is topmost lid 1.Have the projection of two ear patterns in the top part of electric heating cutlery box two side bottom, left side be USB interface, can be connected with computer or portable power source by this interface; Right side projection is that the clockwork spring handle 5 of a clockwork spring 7 can make exterior mechanical can be converted into the elastic potential energy of inner clockwork spring 7 by this handle.Clockwork spring handle 5 bottom also has a trigger switch 6, and trigger switch 6 is used to control reserve battery 14 circuit.The groove of wave-like is arranged at USB interface 4 and outer handle bottom, is convenient to user and rises with hand end.
Splendid attire food and heat generating parts are a cylindrical chamber on this cutlery box top, detachably, are convenient to cleaning.Be layer of metal plate 3 in detachable container 2 bottom, metallic plate 3 inside has electrothermal resistance silk to be wound around.Metallic plate 3 object has two, and one is make delivered heat even, and two is avoid electrothermal resistance silk directly to contact with Sheng food container, avoids security incident occurs.Resistance wire is connected with USB interface 4 by wire on the one hand, forms closed-loop path, in conditions permit situation, is directly connected with electrothermal resistance silk the object reaching heat production by USB interface 4 or portable power source; On the other hand electrothermal resistance silk is had and is connected with lower battery 14 by wire, in the wild or power failure time connect closed-loop path by pressing trigger switch 6, reach heat production and the object that food is incubated.
Reserve battery 14 circuit part, forms closed-loop path by internal charging battery 14, wire, electrothermal resistance silk and trigger switch 6, presses trigger switch 6 and connects circuit, can reach the object of heating equally.When there is no computer and portable power source by the side of, this circuit can be connected to reach the object of resistive heater and then insulated food.
Battery 14 charging device comprises outside and is contained in bottom side clockwork spring 7, clockwork spring 7 tumbler, interior metal rod 8, ellipse metal plate, solenoidal plate is housed, the plate of bar magnet 11, spring and wire are housed.Clockwork spring 7 is connected with interior metal rod 8, metal bar 8 is equipped with three oval sheet metals 9.Circular magnet plate 10 is housed below sheet metal, and bar magnet 11 in three row arrangements onboard.Magnet plate 10 lower plate is equipped with solenoid.There is provided mechanical energy by clockwork spring handle 5 tumbler energetically to clockwork spring 7, clockwork spring 7 rotates and drives metal bar 8 to rotate, and the oval sheet metal 9 on metal bar 8 top rotates.Owing to being ellipse, so the plate that bar magnet 11 is housed of below can be made periodically to move up and down, drive solenoid and bar magnet 11 periodic contact like this, therefore can electric energy be produced, the electric energy produced is passed on chargeable battery 14 by wire and stores, and the saving that so just can realize resource utilizes.Magnet plate 10 is placed on magnet 11 in electric heating cutlery box inside.Solenoid 13 is around on the little bar below magnet 11, and three little bars are placed on helical girth sheets 12 simultaneously.This part main process is: changes mechanical energy is elastic potential energy, and elastic potential energy is converted into mechanical energy, and changes mechanical energy is that electrical power storage is in chargeable battery 14.
When using heat-preservation lunch box, cover lid 1, if switched on power by USB interface 4, then power supply forms loop by USB interface 4 and metallic plate 3, and resistance wire generates heat, the food in heating splendid attire food container.If do not have external power source, then open trigger switch 6, manual wind handle 5 tightens clockwork spring 7, and the changes mechanical energy of user is elastic potential energy by battery 14 charging device, and elastic potential energy is converted into mechanical energy, and changes mechanical energy is that electrical power storage is in chargeable battery 14.Battery 14 and metallic plate 3, trigger switch 6 form loop, and select battery 14 to discharge, resistance wire generates heat, the food in heating splendid attire food container.
The utility model provides a kind of new electrically heating heat-preservation lunch box, charging insulation and self-generation heat-insulating technology is adopted to realize the insulation of food, this new electrically heating heat-preservation lunch box all can be convenient to use when having external power supply in indoor or go out there is no external power supply, not only solve heat insulation effect not good, be not easy to the problem of taking off cleaning, and easy to use, simple to operate, high insulating effect, can commercially promote.
