Abstract
The utility model provides a temperature sensor for an electric hot water bottle and relates to a temperature sensor for the temperature control of the electric hot water bottle. A glass envelope part 6 of a thermal resistor is directly clung to the bottom of an aluminium shell 1, the surrounding of the thermal resistor is filled with heat conducting silicone grease 7 which is separated from epoxy resin 2 for encapsulation by an insulating carboard 3, and a wire lead 4 of the thermal resistor is connected with an electronic control board by an FEP wire 8 and a connector 10. The utility model is arranged on the outer surface of the bottom of an inner container of the water bottle, the temperature sensitive thermal resistor adopts the glass-tube type and has small size as well as can be clung to the bottom of the aluminium shell, the epoxy resin and the heat conducting silicone grease are separated by the insulating carboard, the thermal resistor can quickly sense the change in the water temperature through the heat conducting silicone grease, thereby controlling the temperature and keeping the temperature constant; a chip of the thermal resistor adopts a glass tube to encapsulate and is resistant to the moisture; the thermal resistor is encapsulated inside the aluminium shell by the epoxy resin, which guarantees the insulating resistance greater than 500 megaohms, the sparking resistance voltage on the safety is 1500 volts; the epoxy resin has good leak tightness and the moisture-proof performance of the sensor is obvious.
Description
Technical field
The utility model relates to a kind of temperature sensor that the electric hot water bottle temperature control is used that is used for.
Background technology
The electric hot water bottle main application is to replace insulating pot to heat up water, and except that the function that possesses insulating pot, can also store boiling water and insulation, and safe and reliable, drinking-water is convenient, is applicable to uses such as family, office, hotel.As the important components and parts in the electric heating temperature control circuit of electric hot water bottle, the design of NTC temperature sensor, select for use extremely important.The NTC temperature sensor should satisfy the temperature-sensitive sensitivity, accurately control temperature, but again with the control circuit long-term stable operation, guarantees the safe handling of electric hot water bottle.
The thermistor that is usually used in the NTC temperature sensor now is that high warm sleeve is installed on thermistor, is attached to the water bottle shell and installs, and there is following problem in it: 1, the location is unstable; 2, because the obstruct of heat-shrink tube is arranged, temperature-sensitive is insensitive; 3, because the thermistor lead-in wire exposes, insulating property are poor.
Summary of the invention
The purpose of this utility model aims to provide that a kind of temperature-sensitive is rapid, easy for installation, anti-moisture performance is strong, electric performance stablity, electric hot water bottle temperature sensor safe in utilization.
The implementation of the utility model purpose is, the electric hot water bottle temperature sensor, thermistor lead-in wire 4 connects together by copper strips 9 crimping with FEP electric wire 8, the glass bulb part 6 of thermistor directly is close to the bottom of aluminum hull 1, filled heat-conducting silicone grease 7 around the thermistor, separate by insulating board 3 between the epoxy resin 2 of heat-conducting silicone grease 7 and encapsulation usefulness, be with PE heat-shrink tube 5 outside thermistor lead-in wire 4 and copper strips 9, the FEP electric wire connects the connector 10 that connects with automatically controlled plate.
The utility model is installed in the bottom outer surface of water bottle inner bag, the temperature-sensitive thermistor adopts the glass-tube formula, size is little, can be close to the aluminum hull bottom, custom-designed insulating board separates epoxy resin and heat-conducting silicone grease, by heat-conducting silicone grease, the variation that thermistor can rapidly perception water temperature, thereby control temperature, steady temperature; Thermistor chip itself adopts glass tube encapsulation, moisture-proof gas; Epoxy resin is encapsulated in thermistor in the aluminum hull, and the insulating property aspect can guarantee insulation resistance greater than 500M Ω, breakdown voltage resistant 1500V in the security; Because epoxy resin has good sealing property, the moisture resistance properties of sensor is remarkable.
Design has the installing and locating hole on aluminum hull in advance, and the utility model temperature-sensitive is rapid, easy for installation, anti-moisture performance strong, electric performance stablity, safe in utilization.
Description of drawings

Fig. 2 is that the utility model is at electric hot water bottle bottom scheme of installation
Embodiment
With reference to Fig. 1, the glass bulb part 6 of the utility model thermistor directly is close to the bottom of aluminum hull 1, filled heat-conducting silicone grease 7 around the thermistor, separate by insulating board 3 between the epoxy resin 2 of heat-conducting silicone grease 7 and encapsulation usefulness, thermistor lead-in wire 4 connects automatically controlled plate by FEP electric wire 8, connector 10.
With reference to Fig. 2, the utility model 12 is installed on outside the bottom of water bottle inner bag 11, during the water bottle heating, by thermistor sensing water temperature, when water was heated to boiling, water temperature tended towards stability, the resistance of thermistor also tends towards stability, automatically controlled program utilizes these characteristics to judge that water outlet is boiled, and the pilot lamp on the automatically controlled plate jumps to " insulation " state from " high temperature ", and electric hot water bottle enters holding stage.By the sensing water temperature, regulate and control the break-make of muff heater then during insulation, guarantee that water temperature is constant in a very little scope.
Dry combustion method is judged: if the water bottle dry combustion method, then thermistor can be judged temperature and rises rapidly, surpasses the rate of rise in temperature of normal heating, and then programmed decision is dry combustion method, and the pilot lamp on the automatically controlled plate sends alerting signal, simultaneously outage.
Adding water judges: if add cold water in the water bottle, then thermistor can be judged temperature and descends rapidly, surpasses the temperature decline rate of normal cooling, and then programmed decision is for adding water, and automatically controlled plate switches to heated condition.
