Abstract

The utility model relates to an electric heating cup for automotive vehicles, comprising a cover, a cup body, a handle, and a PTC ceramic heating sheet. The cover is divided into an internal cover and an external cover and has a small hole for steam exhausting. The cup body adopts the double-layer structure of an internal casing and an external casing for heat insulation. The inherent characteristics of the PTC ceramic heating sheet is used to reach the purpose of heating and constant temperature. The utility model adopts a ceramic sheet which works in low voltage and uses electric energy generated by the running of an automotive vehicle as working power supply. The utility model can be used for boiling water, steaming rice, and cooking other foods. The utility model provides convenience for water drinking and dining for drivers in long distance running. The heating of the utility model can be realized without any additional energy sources.

Description

Electric heating cup for motive vehicle

The utility model relates to the technological improvement of daily necessities cup.

General electric cup is to heat with resistance wire, the structure of cup is the individual layer cup, exist weak point to be: the first, with the resistance wire heating, its operating voltage is 220V, if on motor vehicle, use, can't reach requirement, the second, be the individual layer cup, the rim of a cup lid is not tight, and cup water occurs easily to excessive phenomenon when tilting.The 3rd, the individual layer cup can not be incubated.

Not enough in view of existing in the prior art, the utility model purpose has problems for overcoming prior art, and a kind of electric cup that is applicable to motor vehicle is provided, and low voltage operating has constant temperature, different outer characteristics of overflowing.

The utility model main points are to utilize ceramic material PTC sheet inherent characteristic: switching characteristic, and promptly when temperature was raised to switch temperature, resistance increased rapidly, and heating power descends, and realizes constant temperature, PTC sheet switch temperature and structures shape thermostat temperature.

The utility model purpose can realize that this cup comprises lid, cup, handgrip and heating member by following measure, and cup system adopts inner casing, shell double-decker; Heating member is the PTC potsherd, and it is secured to inner casing by connector, between shell, and closely contacts with the inner casing outer ring; Lid is divided into inner cap, enclosing cover, and have aperture.

The utility model purpose can also realize that the PTC potsherd is connected with the motor vehicle cigar lighter by lead, plug, socket by following measure.

The accompanying drawing drawing is described as follows:

Accompanying drawing 1 the utility model electric cup orthogonal view

Below in conjunction with accompanying drawing, in conjunction with the embodiments the utility model is elaborated.Referring to accompanying drawing 1, electric cup comprises handgrip, lid and cup and heating plate, cup divides shell 4 and inner casing 5, outer ring, shell 4 upper end is a screw thread, the bottom is band leg 9, in the shell 4 suits inner casing 5,5 attaching potsherds 6 of shell 4 and inner casing, potsherd 6 attachings contact with inner casing 5 outer rings by reed 7, and reed 7 installs with shell 4.Cup enclosing cover 2 and inner cap 3 have an aperture, and cup enclosing cover 2 inner rings are screw thread.

Leg 9 attachings of shell 4 socket 8, socket 8 one ends are connected with potsherd 6 by lead, the other end is connected with the motor vehicle cigar lighter.

Inner casing 5 is to make or other metal material of the aluminium material of good heat conductivity, and shell 4 is with the non-conductive material such as the plastic production of insulation again.Potsherd 6 adopts the PTC sheet.

The utility model also can be made automobile-use electric cooker electric rice cooker.

Use the utility model electric cup, inject water in cup, put inner cap, screw thread screws a glass enclosing cover, makes that water is not excessive to be dropped down, and is power supply with motor-driven vehicle going generating electric energy, and maximum current is less than 17 amperes, and regular price gasoline car power supply is 12V, and the diesel locomotive power supply is 24V.Cigarette lighter plug inserts socket, potsherd energising back heating, and electric energy transfers heat energy to, conducts heat by the aluminium inner casing, boils water in the cup, and steam is emerged by aperture.The utility model potsherd requires to select suitable low voltage operating for use according to invention, can make to be heated the slice, thin piece that food keeps 100 ℃ of-105 ℃ of temperature ranges, and its temperature control characteristic, water in the cup keeps constant temperature.Not only be used for boil water, also can be used to boil in a covered pot over a slow fire rice and cook food.The driver drinks water and has a meal on the suitable long-distance motor vehicle, and very big convenience is provided.

The utility model compared with prior art has the following advantages: the first, and heating Method changes resistance wire for to use potsherd, good reliability, long service life. The resistance wire aging phenomenon can not take place. The second, cup is the inside and outside shell double-decker, and the space is left in the centre, forms thermal insulation layer, reduces thermal loss. The 3rd, shell, lid are threaded into connection, can prevent from dropping down the water phenomenon. The 4th, cup enclosing cover, inner cap have aperture, are used for emitting the usefulness of steam, and heating process explosion can not take place. The 5th, use the potsherd of switching characteristic to be heating member, have the good effect of automatic constant-temperature. The 6th, the scope of application is wide, is not only to boil water, and can also be used to cook rice over a slow fire, and boils and burns other food, and be fit to very much truckie and use, the 7th, low voltage operating is power supply with the motor-driven vehicle going electric energy only. Energy problem during the solution driver drives a vehicle on the way.
