Description
Technical field
The utility model is related to a kind of lunch box.
Background technology
Lunch box is a kind of box for being specifically used to fill food, and aluminium, stainless steel, plastics are used greatly and are made.Incubation canteen be
Lagging casing has been added outside common lunch box, has had and foamed plastics is filled in inside and outside two layers, then metallic film is plated with internal layer and has been constituted.
The loss of heat is reduced in terms of conduction, radiation, convection current three.But, food, band of going out such as morning are stored to the long period
Meal, when being eaten to noon, even if there is insulating foam layer, food still cools off because of heat loss.The talent must not by micro-wave oven this
Food in the instrument lunch box capable of heating of sample, it is cumbersome.
The content of the invention
The utility model patent provides a kind of lunch box, can keep the food in lunch box in fixed temperature, and carry
It is quick using being quite convenient to.
Above-mentioned technical problem, lunch box of the present utility model, including lid and box body are solved, the lid spiral cover is in box body
On, lid and box body are provided with the screw thread cooperated, and the box body includes shell and metal inner tube, shell and metal inner tube it
Between be provided with polyurethane insulation coating, in polyurethane insulation coating be provided with multiple annular cavities, be marked with indifferent gas in the cavity
Body；Heated base is had in metal inner tube, electric heating element and pcb board are provided with heated base, pcb board is provided with temperature sense
Device, thermosistor and timer, electric heating element and pcb board electrical connection are answered, USB interface, the USB are provided with the outside of heated base
The terminal of interface is fixed on pcb board.
Said structure, inert gas is marked with due to being provided with polyurethane insulation coating between shell and metal inner tube, and being provided with
Cavity, the loss of heat can be completely cut off to large extent, and keep the temperature of food.And the electric heating element energy root of heated base
According to needing to make up the heat loss of food, food is maintained at specified temperature.
Further, the outside of heated base be provided with switch key, temperature adjustment button, regularly button, the switch key,
Temperature adjustment button, regularly button are electrically connected with pcb board respectively, can set holding temperature and time, meet different food insulation temperature
The demand of degree.
Further, heat-insulation layer is provided with lid, it is to avoid heat scatters and disappears from lid.
Further, it is convenient that lid is rotated into above box body provided with rotation lever on lid.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Come that the utility model is described in more detail with reference to the accompanying drawings and detailed description.
As shown in Figure 1, the present embodiment is a kind of lunch box, including lid 1 and box body 2, the spiral cover of lid 1 on box body 2,
Lid 1 and box body 2 are convenient that lid 1 is rotated into box body provided with rotation lever 3 on lid 1 provided with the screw thread cooperated
2 tops.Include shell 31 and metal inner tube 32 in the box body 2, polyurethane heat-insulation is provided between shell 31 and metal inner tube 32
Layer 33, multiple annular cavities 34 are provided with polyurethane insulation coating 33, inert gas is marked with the cavity 34；In metal
Inner bag 32 has heated base 4, and electric heating element 41 and pcb board 42 are provided with heated base 4, and pcb board 42 is provided with temperature
Inductor 421, thermosistor 422 and timer 423, electric heating element 41 and pcb board 42 are electrically connected, and are set in the outside of heated base 4
There is USB interface 43, the terminal of the USB interface 43 is fixed on pcb board 42.The outside of heated base 4 provided with switch key 6,
Temperature adjustment button 7, regularly button 8, the switch key 6, temperature adjustment button 7, regularly button 8 are electrically connected with pcb board 42 respectively, can
Holding temperature and time are set, the demand of different food holding temperatures is met.During work, food is placed in lunch box, due to
Polyurethane insulation coating 33 is provided between shell 31 and metal inner tube 32, and provided with the cavity 34 for being marked with inert gas, can be larger
Completely cut off to limit the loss of heat, and keep the temperature of food.When needing to keep steady temperature in lunch box, by USB power source plug
USB interface 43 is inserted, temperature is set by temperature adjustment button 7, and the electric heating element 41 of heated base 4 can make up food as needed
The heat loss of thing, specified temperature is maintained at by food.Present computer and charger for mobile phone are widely used, therefore connect electricity to lunch box
Heating is also very convenient.
