Description

Electric heating bottle

The utility model relates to a kind of internal heat type liquid beverage vessel of heating, and the band that it comprises bottle, base, temperature control circuit and electric heater is housed connects screw thread and connects the bottle end of bayonet socket.

In daily life, people often need be with coffee, liquid beverages such as drinks are heated, have in a lot of families that all will repeatedly be child's heating milk and beverage every day in infant's the family, because it is less to be heated amount of fluid, heating-up temperature is difficult for grasping, also bother, for addressing this problem, some manufacturer production some electric cups and some Electric heating household utensils, the said goods is owing to mostly adopt external-heat heating promptly at cup external device (ED) electric heater or water proof is heated or radiant type heats up in design, warm-up time is long, and the thermal efficiency is low, controls heating-up temperature and heat time heating time inaccuracy, use cumbersome, the milk that one bottle of capacity of the warm milk of electricity device heating is 200ml needs 25～～30 fens clock times, and if the electric heater of external-heat to be heated the liquid temperature rise too high, the overflow container outside flows on the heater also danger close.

The utility model is exactly that a kind of electric heating bottle that can safely, rapidly, easily liquid beverage be heated to suitable human body consumption temperature will be provided.

The purpose of this utility model can realize by taking following measure: in the bottle inside, the end that has connection screw thread and connection bayonet socket, power supply plate electric heater is housed, can directly heats to liquid beverage, also can dismantle easily, install and clean.Have on the base of temperature controller and the bottle end connects the supporting connection hook of bayonet socket being equipped with, can connect and dismounting, can stop automatically heating when in bottle, being heated liquid and being heated to preset time and temperature with bottle.

Below in conjunction with accompanying drawing the utility model is elaborated.

Fig. 1 is an electric heating bottle structure schematic diagram, and Fig. 2 is an electric heating bottle electrical schematic diagram, and Fig. 3 is the schematic diagram of device common electrical heat pipe, and Fig. 4 is a bottle bottom profile schematic diagram, and Fig. 5 is a bottle schematic bottom view.

Electric heating bottle as shown in the figure, the bottom of bottle (1) at it has dismountable connection screw thread, with the bottle end (2) that bottle (1) links on have and connection screw thread that bottle (1) matches, between bottle (1) and bottle (2), a sealing ring (3) is arranged, the bottle end (2) is a multifaceted assembly, electric heater (4) is housed in its interlayer, electric heater (4) can use Electric radiant Heating Film or electric ceramic, at the bottom of carrying out with injection moulding bottle when (2), coated electrothermal film material on its base plane, or device electrothermal ceramic plate, the thermal insulation material is preferably inserted in outer end, bottom at it, draw power supply lead wire then, fix outermost layer interlayer and power supply plate (5), (2) two bottom sides has the connection bayonet socket at the bottom of bottle, on base (6) and the bottle end (2) contacted contact-making surface, be with flexible power supply to contact pile crown (10), can contact conduction with the power source connecting (5) of (2) bottom at the bottom of the bottle, base concave volume both sides are provided with the hook of protrusion, can connect in (2) bottom at the bottom of the bottle and pin the bottle end and whole bottle when bayonet socket screws in, the timing temperature control circuit that temperature control circuit in the base (6) adopts bidirectional triode thyristor and time-base integrated circuit to constitute, electric heater with bottle in liquid when being heated to the scheduled time and temperature, regularly temperature control circuit control bidirectional triode thyristor cuts off the power supply automatically, stop to heat, the scope of temperature controller adjustment and control is according to being heated how much selecting of liquid in the electric heating bottle, the power of electric heater (4) is 150～～200 watts.

Circuit theory as shown in Figure 2, JR in the circuit is electric heater (4), D is Light-Emitting Diode burner on light (9), A is heat button switch (11), R is that timing resistor is temperature controller (7), C is a time capacitor, changes the numerical value of resistance R and timing capacitor C, and changed heat time heating time within zero to tens of minutes.

VT in the circuit is operated on off state, is used for triggering time-base integrated circuit NE555 and makes it to enter definition status.Integrated circuit NE555 be connected into timing mode and and bidirectional triode thyristor VS composition self-holding switch, bidirectional triode thyristor VS is in cut-off state at ordinary times, electric heater JR does not work, work as power connection, when heat button A is pressed, bidirectional triode thyristor VS conducting, electric heater JR begins heating, burner on light D is bright, supply voltage is through capacitor C4 step-down simultaneously, diode D2 rectification, voltage-stabiliser tube DW voltage stabilizing, for control and delay circuit 9 volts of dc sources are provided, give capacitor C 1 charging, in the moment of capacitor C 1 charging, the ground level of transistor VT is a high level, the VT conducting, make the 2 pin ground connection of integrated circuit NE555, triggering NE555 makes its 3 pin be output as high level, after capacitor C 1 charging finishes, triode VT ends because of the ground level current potential reduces, this moment, 2 pin of NE555 were reduced to high level, NE555 enters definition status, this moment, bidirectional triode thyristor VS was in conducting state always, electric heater JR continues heating, charging along with capacitor C, current potential on 6 pin of integrated circuit NE555 is more and more higher, when it is higher than 2/3rds supply voltage promptly 6 volts the time, the 3 pin output signals upset of NE555 is low level, bidirectional triode thyristor VS loses triggering level and ends, cut off the heating power supply of electric heater JR, heating stops, burner on light D extinguishes, at this moment, liquid in the electric heating bottle just in time is heated to temperature required, once heating is finished, what this temperature control circuit was controlled is the time of electric heater heating, reach the order ground of accurate control heating-up temperature by control to heat time heating time, therefore, no matter many and few liquid capacity in the electric heating bottle is, electric heater all is operated in the full power state, heat time heating time is very short, and be 200ml as one bottle of capacity milk only needs 2～～3 fens clock times (40 ℃ Celsius is the temperature that suitable human body is drunk) when being heated to 40 ℃ under the room temperature state or when Celsius temperature is 10 ℃, as need with Hot Coffee, teas, during liquid such as drinks, it is not high enough as the suspicion temperature after once heating is finished, can press a heat button again, continue heating, until reaching required temperature of drinking.
