The lunch box that current people's daily life is used mainly is metal species, plastics and foam class lunch box, and major part can only play a kind of effect of the dish of filling a bowl with rice.China Patent No. 98248442.9 discloses a kind of electrical heating lunch box, is made of asbestos cloth, interior case, outer case lid, outer case, heating plate, socket.It is characterized in that outer case lid is equipped with venthole, and in the middle of outer container and the interior case heat-barrier material is arranged, the inwall of interior case is undulatory.The patent No. 200320112119.5 discloses a kind of chargeable from heating lunch box, but its structure comprises the box body of a folding, and the bottom of box body is provided with interlayer, and being provided with in the interlayer can be from the electric heating device of heating, and the box wall is provided with corresponding patch jack.Described electric heating device is disposed with zone of heating, battery layers from top to bottom.Be connected with lead between zone of heating and the battery layers, battery layers can be made of the battery arranged in series more than two or two.200820113345.8 1 kinds of electrical heating lunch boxes of the patent No., it is characterized in that lunch box connects the heat conduction box, there is manhole appendix heat conduction box side, by manhole appendix liquid is packed in the heat conduction box, and be connected and fixed seat at the bottom of the heat conduction box box, holder connects electric heating element and line box respectively, and the line box connects return spring, by return spring with in the coil of wire lambda line box, lead attachment plug.The patent No. 200710032073.9 discloses a kind of heating lunch box, and this heating lunch box uses dry cell, often will to change battery consumption big.Though above lunch box has heating function, all can not vacuumize sealing, do not have fresh-keeping function.

The utility model content

The purpose of this utility model is to provide a kind of family expenses vacuum freshness retaining to heat lunch box automatically, this vacuum freshness retaining lunch box have vacuumize, functions such as heating, little, the practical convenient of power consumption automatically.

The purpose of this utility model is achieved through the following technical solutions: vacuum freshness retaining heats lunch box automatically, comprises lid, box body and heating plate, and lid is provided with the check valve of bleeding on the switch of bleeding, the switch, seal is provided with silicone rubber O-ring; The box body bottom is provided with heating plate, and heating plate is a stainless steel material, and heating plate is provided with E-communication rectifier, charging accumulate pond and heat-transfer matcrial; Bottom of box body is provided with heating temperature control switch, attaching plug.

A dividing plate is divided into dress meal chamber, dress dish chamber with box body in the box body; Be provided with the insulation layer of vacuum-pumping between box body outer wall and the box inner bag.

Socket connects diode D1 in the power circuit, and diode D1 connects regulator block U1 input, and the U1 output connects the positive pole of nickel manganese H accumulator, constitutes charging circuit; The positive pole of battery connects switch S 1, connects the fast SG3663 input of the mould that boosts, and the anode of the output termination electric heater of boost module constitutes heating line.

This lunch box adopts the DC boosting heating, is raised to 12V from 5V, and power 12W adopts the 9V DC charging, the overheated then deenergization of battery.Connect civil power during use, the E-communication rectifier links with charging accumulate pond and begins charging, and it is stand-by to be full of the electricity back; Food is packed into behind the box body, covers lid and shuts the switch of bleeding, and aims at the check valve of bleeding with the head of bleeding, and extracts the air formation vacuum in box body and the insulating out; Press gauge tap, heating plate begins heating, and gauge tap cut off the power supply automatically when temperature arrived the setting position.

Good effect of the present utility model is: have vacuum heat-insulating, fresh-keeping function is controlled, heated automatically to temperature automatically.
