Description
Technical Field
The utility model relates to the field of electric heating evaporators, in particular to an electric heating evaporator capable of accurately measuring temperature.
Background
In the field of electric heating evaporators, the evaporators are generally required to be replaced, taken out for cleaning and the like, so that accurate temperature measurement becomes a difficult problem, most replaceable electric heating evaporators on the market are driven by fixed power, temperature measurement is not carried out, and a few electric heating evaporators with temperature measurement can not achieve the purpose of accurate temperature measurement by utilizing the rough temperature measurement of the TCR (temperature coefficient of resistance) variable quantity of a heating wire. If the integrated non-replaceable electric heating evaporator is adopted, a temperature measuring probe can be added to measure the temperature of the heating pot, so that the temperature can be measured accurately, but the problem that the evaporator cannot be replaced exists.
Specifically, there are several commonly used electrically heated evaporator technologies:
1) the temperature of the evaporator can be estimated only by means of the driving power without a temperature measuring function, the mode is simple, but the difference between the actual temperature and the estimated temperature is large, and meanwhile the temperature of the evaporator is seriously influenced by the quantity of evaporated matters in the evaporator.
2) The evaporator has double functions of heating the evaporator by utilizing the TCR characteristic of the heating element, and measuring temperature by utilizing the TCR characteristic of the heating element. The evaporator has large evaporation power, so that the corresponding heating element has small resistance value and small absolute value of resistance value change, and if the evaporator is used on a product of a non-replaceable evaporator, the resistance value error of a contact circuit (the contact part of a heating wire in a container and a control circuit outside the container) is not existed (the error of the contact resistor is possibly larger than the variation of the resistance value caused by temperature, and the resistance value of the contact resistor is unstable), and the control circuit can better process the error. If the evaporator is used in a replaceable evaporator, the error of the contact resistance affects more than the change of the resistance value of the heating element, and the temperature cannot be accurately controlled.
3) The temperature sensor is connected externally to measure the temperature of the evaporator container, and the mode is generally used in a non-replaceable evaporator.
In summary, the current electric heating evaporator can not realize the purposes of accurate temperature measurement and replacement.
