Abstract
The utility model discloses an auto-break water heater whose electrothermal element is an electric heating element fixed on a water bottle plug. The utility model is characterized in that the center of the bottle plug is provided with temperature detecting element which is composed of a sleeve and a piston in the sleeve; an electric switch which is composed of a circular cone on the top of the piston and a conducting strip above the piston is arranged in the signal input end of a temperature control circuit. The piston can be moved by the heat expansion of the air to turn on the switch; then the temperature control circuit is triggered; finally the conduction of the controlled silicon which is connect in series with the power source circuit of the electric heating element is replaced by cutoff, so the electric heating element stops heating. The utility model has the advantages that the temperature altering and controlling of the water heater for a water bottle can be realized; the use is safe.
Description
The utility model relates to electric instant water heater.More particularly, be a kind of by being fixed on the water bottle instant water heater of water bottle electric heating element beyond the Great Wall as electric heating element.
At present, the water bottle instant water heater that people generally use is a fixing electric heating element on the cork cock body only, is directly controlled the break-make of electric heating element power supply by attaching plug or mains switch.During use, must there be the special messenger to keep an eye on.Otherwise, if can not after water boils, in time cut off the electricity supply, very easily cause water heater to damage, perhaps accident such as supply line's short circuit owing to overheated.In addition, though cork itself has insulation property, because the conductivity that has of institute's water content wherein when using is brought unsafe factor to use.
The purpose of this utility model is to avoid the deficiencies in the prior art part, and a kind of safe and reliable, electric heater of autotomying of not needing the special messenger to keep an eye on is provided.
This product is achieved through the following technical solutions with novel purpose.
The utility model is an electric heating element to be fixed on water bottle electric heating element beyond the Great Wall.
Feature of the present utility model is:
A, detector unit is set in bottle stopper central authorities.Described detector unit is made of the sleeve pipe of upper end open, lower end sealing and the even part piston that is positioned at sleeve pipe central authorities, and the upper end of described piston is a cone, and the conducting strip that is connected the adjusting screw(rod) bottom is positioned at the piston top;
B, the electric switch K that is made of the top and the conducting strip of piston moving up and down are serially connected in the temperature control circuit signal input part, described temperature control circuit comprises the bistable circuit of accepting the switch triggering signal and accepts the bistable circuit output signal, and being operated in the thyristor of conducting or cut-off state, described thyristor is connected in series in the electric power loop of electric heating element RT.
Feature of the present utility model is that also described water bottle plug is made of upper and lower two parts, and its underpart is the cork body, and top is moulding, and adjusting screw(rod), sleeve pipe upper end and temperature control circuit all are arranged on water bottle beyond the Great Wall in portion's moulding center cavity.
The utlity model has following advantage.
1, the utility model utilizes the principle of air expanded by heating to make detector unit, realizes choosing temperature arbitrarily, temperature control, is very easy to water bottle instant water heater's user, it is simple in structure, action accurately and reliably.
2, to adopt the latter half be that cork body, the first half are the bottle stopper structure of moulding to the utility model, not only guaranteed heat-insulating property preferably, and eliminated in the prior art because of the bottle stopper suction and caused to a certain extent hazards that electric leakage produced.Increased substantially coefficient of safety.
Fig. 1 is the utility model bottle stopper structural representation.
Fig. 2 is the utility model circuit theory diagrams.
Number in the figure: 1, electric heating element, 2, sleeve pipe, 3, piston, 4, conducting strip, 5, adjusting screw(rod), 6, moulding, 7, the cork body, 8, adjusting knob.
By the following examples, in conjunction with the accompanying drawings the utility model is further described.
Embodiment:
Referring to Fig. 1, the sleeve pipe 2 of upper end open, lower end sealing adopts glass bushing, and piston 3 is its even part, and the upper end of piston 3 is a cone.The bottom that cork body 7 is fixed on moulding 6 is all passed in the upper end of electric heating element and sleeve pipe 2.Moulding 6 center cavity internal fixation adjusting screw(rod)s 5, suit temperature control circuit printed panel on the adjusting screw(rod) 5, adjusting screw(rod) 5 bottoms connect conducting strip 4, and conducting strip 4 is positioned at the top of piston 3, and adjusting screw(rod) 5 tops connect adjusting knob 8.Rotate adjusting knob 8, can drive conducting strips 4 upper and lower displacements, change distance between piston 3 tops and the conducting strip 4, finish the temperature setting with this by adjusting screw(rod) 5.
Referring to Fig. 2, the electric switch K that is made of conducting strip 4 and piston 3 tops is arranged on the temperature control circuit signal input part.Comprise the bistable circuit that constitutes by Q1, Q2, Q3, Q4 in the temperature control circuit and be connected in series in thyristor CT in the electric heating element RT electric power loop.Triode Q5, Q6, diode D4, D5, resistance R 9, R10 and capacitor C 4, C5 constitute the thyristor operating angle control circuit.
In the use, energized, bistable circuit is devoted oneself to work, and R2+R4＞R5+R3 is set, and therefore, circuit prior is stabilized in Q3 by, Q2 and Q4 conducting state.At this moment, Q5, Q6 conducting, CT is conducting thereupon, electric heating element RT heating power.When temperature reaches set point, electric switch K closure, V1 charges to capacitor C 3 through R1, K, after the C3 time-delay, the Q1 conducting, bistable electro triggers upset, the Q3 conducting, and Q2 ends, and Q5, Q5 end, CT ends thereupon, and electric heating element RT power supply open circuit stops heating, until pulling up attaching plug.The time-delay of capacitor C 3 has been satisfied when water temperature reaches 100 ℃, continues heating 1～3 minute, so that kill bacteria.
In the present embodiment energy consumption wait bide one's time ≯ 0.006, during work ≯ 0.018W.
