Utility model content

Technical problem to be solved in the utility model is：A kind of lunch box capable of heating is provided, by USB power source, vehicle power Or city's electric energy carries out lunch box heating.

Technical scheme is used by the utility model solves its technical problem：

Lunch box capable of heating, including box body, the box body have receiving space, and are provided with the opening for leading to receiving space, The wall of the receiving space periphery is the double-deck wall of closing, and dielectric cavity is provided with double-deck wall, and receiving space is opened The end face at mouth edge is additionally provided with the perforate of connection dielectric cavity；Heating wire is provided with the dielectric cavity, heating wire also connects Power interface is connected to, the power interface exposes from box portion outside；The power interface is USB interface or vehicle power interface, Or the power interface is also associated with power supply adaptor.

Further, connecting the perforate of dielectric cavity includes hand-hole and steam vent, and the hand-hole is taper type, And the small end connection dielectric cavity of taper type.

Further, in addition to the lid of receiving space opening is covered, the lid size covers opening for receiving space Mouth outer, and lid is close to the shape that the face of the receiving space is that middle part raises up.

The beneficial effects of the utility model are：This lunch box capable of heating, chamber wall use double-decker, the dielectric cavity of chamber wall Water can be filled, the heating wire set in dielectric cavity can heat water, and then the food in lunch box capable of heating, heating wire can lead to The power supply of the diversified forms such as USB power source, vehicle power or civil power is crossed, it is easy to use.

Brief description of the drawings

Fig. 1 is the schematic diagram of lunch box capable of heating of the present utility model；

Reference is in figure：Box body 1, dielectric cavity 11, hand-hole 111, steam vent 112, receiving space 12, power supply connect Mouth 13, heating wire 14, power supply adaptor 15, lid 2.

Embodiment

The utility model is further illustrated with reference to the accompanying drawings and examples：

Lunch box capable of heating, including box body 1, the box body 1 has receiving space 12, and is provided with and leads to receiving space 12 Opening, the wall of the periphery of receiving space 12 is the double-deck wall of closing, and dielectric cavity 11 is provided with double-deck wall, holds Receive the opening edge edge of space 12 end face be additionally provided with connection dielectric cavity 11 perforate；Electric heating is provided with the dielectric cavity 11 Silk 14, heating wire 14 is also associated with power interface 13, and the power interface 13 exposes outside box body 1；The power interface 13 Power supply adaptor 15 is also associated with for USB interface or vehicle power interface, or the power interface 13.

As shown in Figure 1：This lunch box capable of heating, the receiving space 12 of box body 1 is used to contain food, or other need a small amount of add The material of heat.

The wall of the periphery of receiving space 12 is the double-deck wall of closing, is that the inside and outside layer of double-deck wall is connected to be formed and closed Ring-type, loop-like inside, i.e., there is dielectric cavity 11 between inside and outside layer wall.For storing the liquid of water etc, dielectric cavity The adstante febre of heating wire 14 in 11, the heat of heating wire can quickly transmit feedwater, and water temperature rises, and avoids heating wire from overheating.It is high The food that warm water transfers heat in box body 1 again, is avoided that the problem of local temperature is too high.

The end face on the opening edge edge of receiving space 12 is additionally provided with the perforate of connection dielectric cavity 11, can pass through above-mentioned perforate To the injection heat transfer medium of dielectric cavity 11, the excessive gas in dielectric cavity 11 can also be discharged by perforate.

Heating wire 14 is connected to outside box body 1 by power interface 13, such as power interface 13 can be USB interface, make The power interface of lunch box can be connected with existing mobile phone USB charger, or existing 5 volts of portable power sources with USB interface 13, lunch box is heated.Power interface 13 can also be vehicle power interface, by corresponding line, using vehicle power to meal Box heats.

Or power interface 13 can also be and be connected with power supply adaptor 15, such as the adapter of 220 volts of civil powers, after decompression For the electric-heating-wire-heating of lunch box, adapter can use prior art.

The perforate of foregoing dielectric cavity 11 can take into account the function of injection and exhaust, it is furthermore preferred that can be hand-hole 111 and steam vent 112 set respectively, such as the perforate includes hand-hole 111 and steam vent 112, and the hand-hole 111 is cone Platform shape, and the small end connection dielectric cavity 11 of taper type.The hand-hole 111 of taper type is easy to liquid to inject, and steam vent 112 is used for The gas discharge of dielectric cavity 11.

Heating wire electrified regulation is discharged to steam to a certain degree, is had from the perforate of dielectric cavity 11, is protected to improve heating Temp effect, it is preferred that can be the lid 2 for also including covering the opening of receiving space 12, it is empty that the size of lid 2 covers receiving Between 12 opening outer, and lid 2 is the shape that raises up of middle part close to the face of the receiving space 12.

As shown in figure 1, the outer edge that the outer edge covering receiving space 12 of lid 2 is open, the perforate of dielectric cavity 11 is allowed In the range of the covering of lid 2.Lid 2 is close to the shape that the face of receiving space 12 is that middle part raises up, from dielectric cavity The steam that 11 perforates spray is stopped by lid 2, and is flowed to the central region of lid 2, and steam aggregation subsequently enters receiving space 12, by heat foods.
