According to the heating and heat-preserving lunch box disclosed by the invention, the storage battery is used for supplying power to the electric heating plate, the lunch box can be heated after the switch is turned on, the heat preservation effect of the lunch box is improved, and stored food is prevented from being cooled.
Description
Technical field
The invention discloses a kind of heated heat-preserving lunch box, relate to tableware manufacturing technology field.
Background technology
Lunch box is a kind of conventional tableware, in daily life, often need to use.In the time of cold weather, cooling very fast of the food stored in lunch box, affects the mouthfeel of food.In prior art, the designing and making great majority of incubation canteen are the improvement of making for insulation material and concrete structure, seldom there is lunch box itself that the design of heater is provided, even if having some in conjunction with the incubation canteen of heater, also there is complex structure, heating effect is undesirable, uses the many disadvantages such as inconvenient.Meanwhile, because user only cannot judge the internal temperature of incubation canteen conventionally with outward appearance, to use, bring further inconvenience.
Summary of the invention
Technical problem to be solved by this invention is: for the defect of prior art, provide a kind of heated heat-preserving lunch box.
The present invention is for solving the problems of the technologies described above by the following technical solutions:
, comprise box body, lid, the rotating shaft that box body is connected with one end of lid, also comprise battery, electric heating piece, bed course, switch, thermometer, display; Described battery and electric heating piece are all arranged at the lower end of box body, and switch is arranged at the side of box body, and the lower end of battery and electric heating piece is also provided with bed course; Battery is connected with electric heating piece by switch; Thermometer is arranged at lid inner side, and display is arranged at lid outside, and display is also connected respectively at thermometer, battery.
As present invention further optimization scheme, described battery is charged lithium cells.
As present invention further optimization scheme, described electric heating piece is silicon rubber electric heating piece.
As present invention further optimization scheme, described bed course is rubber blanket.
The present invention adopts above technical scheme compared with prior art, there is following technique effect: heated heat-preserving lunch box disclosed in this invention utilizes battery to power to heating plate, after opening switch, can automatically to lunch box, heat, effectively increase the heat insulation effect of lunch box, avoided the cooling of stored food.
Accompanying drawing explanation
Fig. 1 is connection diagram in kind of the present invention,
Wherein: 1. box body, 2. lid, 3. rotating shaft, 4. battery, 5. electric heating piece, 6. bed course, 7. switch, 8. thermometer, 9. display.
Fig. 2 is circuit connection diagram of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, technical scheme of the present invention is described in further detail:
As shown in Figure 1, a kind of heated heat-preserving lunch box, comprises box body, lid, the rotating shaft that box body is connected with one end of lid to connection diagram in kind of the present invention, also comprises battery, electric heating piece, bed course, switch, thermometer, display; Described battery and electric heating piece are all arranged at the lower end of box body, and switch is arranged at the side of box body, and the lower end of battery and electric heating piece is also provided with bed course; Battery is connected with electric heating piece by switch; Thermometer is arranged at lid inner side, and display is arranged at lid outside, and display is also connected respectively at thermometer, battery.Because incubation canteen itself is a kind of common tableware, its concrete structure and the material using can be used for reference the technical characterictic of public office common-sense in prior art, the present invention is in the further improvement to existing incubation canteen, and to lunch box, this existing design on structure and material is not specifically limited.
As present invention further optimization scheme, described battery is charged lithium cells.Charged lithium cells capacitance is large, and once charging can be used as the power supply use of long period.
As present invention further optimization scheme, described electric heating piece is silicon rubber electric heating piece.Silicon rubber electric heating piece is exactly a kind of soft flexible film-form electrothermal device.It is that pool shape, thread metallic heating body are distributed between the glass fabric that is coated with high-temperature-resisting silicon rubber, through hot press moulding, are formed.Its body is thin, and thick 0.8 ~ 1.5MM, light weight, general conventionally, 1.3 ~ 1.9 kilograms every square.Heating power is rapid, temperature rise is fast, has that heating face is large, even, weather-proof, the corrosion resistant of generating heat, environmental protection, the characteristic that fire-retardant, easy for installation, the life-span is long, dielectric strength is high.
As present invention further optimization scheme, described bed course is rubber blanket.Rubber blanket had both played the effect of insulation, had again anti-skidding effect concurrently, and the lunch box that is is more stable in placing the process of using.
As shown in Figure 2, battery is used as electric supply installation circuit connection diagram of the present invention, and when adopting charged lithium cells as battery, once charging can meet the needs of heating and thermal insulation on the same day.Switch is controlled startup or the shutoff of heating plate, in needs heating, opens switch, also can utilize at ordinary times the structure and material of incubation canteen itself to be incubated, and can further extend the time of insulation like this.; Thermometer is arranged at lid inner side, and display is arranged at lid outside, and display is also connected respectively at thermometer, battery.Thermometer detects the temperature of lunch box inside, temperature information is presented on display simultaneously, facilitates user to judge whether to need opening switch to carry out heating and thermal insulation.
By reference to the accompanying drawings embodiments of the present invention are explained in detail above, but the present invention is not limited to above-mentioned embodiment, in the ken possessing those of ordinary skills, can also under the prerequisite that does not depart from aim of the present invention, makes a variety of changes.
