Abstract
The utility model relates to a safety automatic insulating electric-heating thermos bottle, composed of a box body, a box cover, a cooling board, a circuit board, a power supply line, a heat generating wire, a wire seat, a wire hood, a boiled water bottle, and a heating circuit. The utility model use a water conducting strip which only can be heated with water and uses the steam after the water is boiled to cause the temperature control strip to act and close the switch. The utility model is characterized in that the temperature rising speed is high, the heat efficiency is as high as 100%, the utility model adopts a glass vacuum heat preservation bottle liner, the heat preservation performance is good, the volume is small, the cost is low, the bottle liner is made of glass, the material property of the glass is more stable than stainless steel, and the boiled water can not be polluted and is sanitary.
Description
The utility model relates to the electric-heating thermos new varieties.
Existing electric-heating thermos specification is various in style, but all has following drawback: the one, and adopt electric hot plate to the heating of steel inner bag, programming rate is slow, and the thermal efficiency is low; The 2nd, the stainless steel inner container heat insulating ability is poor, need constantly to use electrical heat tracing, and after water is boiled, still very power consumption; The 3rd, volume is big, cost height, every more than 100 yuan at least, one over thousands of yuan at most; The 4th, also there is unsafe factor, in case go out for a long time, forgotten powered-down, power consumption for a long time or water dryout, and cause danger.
The purpose of this utility model provides a kind of quick heating, thermal efficiency height, good heat preservation performance, safety, the safety automatic heat-preserving electric-heating thermos that volume is little, cost is low.
The utility model is to adopt vacuum heat-preserving, the common vacuum flask of good heat preservation performance, and the heating wire assembly directly injected in the water in bottle heat, make and heat up fast, thermal efficiency height reaches 100%, utilize the electric conductivity of water again, in water in bottle, place water conducting plate, the water heating of then switching on arranged, anhydrous or water level be lower than safety line then mode such as powered-down achieve the goal.
The utility model characteristics: the one, programming rate is fast, and thermal efficiency height reaches 100%; The 2nd, glass evacuated glass liner of thermos good heat preservation performance, after water was boiled, the insulation power consumption was few; The 3rd, volume is little, and cost is low; The 4th, glass refills, material character is more stable than stainless steel courage, can not pollute boiling water, health.
Below in conjunction with accompanying drawing embodiment is described:
Fig. 1 is this electric-heating thermos, the electric heater schematic perspective view.
Fig. 2 is this electric-heating thermos, the electric heater schematic diagram.
Fig. 3 is the three-dimensional sketch (partly cut-away) of this electric-heating thermos.
With reference to Fig. 1-3, this electric-heating thermos is made up of box body (1), lid (2), heat sink (3), circuit board (4), power line (5), plug (6), lead (7), heating wire cover (8), heating wire seat (9), vacuum flask (10) and heater circuit.Heater circuit is by bi-directional thyristor switch (K), temperature control sheet (g), water conducting plate (F), heating wire (R
