Wire guide connects four the two of binding post opposite side binding posts of switch.Viewing lens is installed, back shroud is put into solution bottle,
Turn on the power, thermostat is to start working, the surface temperature of PTC heat generating cores here by Power Control add heat-barrier material control or
Controlled by Power Control plus thermostat, because the heating power of PTC heat generating cores is influenced by ambient temperature, so the work(in low temperature
Rate rises, the power drop in high temperature, and surface temperature control tool has certain effect, and adds heat-barrier material or temperature detect switch (TDS) is auxiliary
Effect is helped, the precise control of temperature is further realized.Realize being controlled by the feedback to variation of ambient temperature the table of heat generating component
Face temperature, realization enters trip temperature opened loop control to the solution temperature in thermostat.
Another implementation method of the invention, by shell, heat-generating pipe, temperature sensor, photoelectric tube, switch, integrated electricity
Road plate, viewing lens, back shroud composition.Here shell is same with the shell phase of implementation method one, repeats no more here, and heat-generating pipe is installed
In in the first irregularly-shaped hole, temperature sensor is installed in the second irregularly-shaped hole, and conduction oil, conduction oil are poured into around the column of cavity one
Liquid level is slightly above column, and the bottom connection with the solution bottle being put into is touched, and photoelectric tube is installed in the 3rd irregularly-shaped hole, for anti-
The surplus of solution in feedback solution bottle body；Heat-generating pipe, temperature sensor, the line of photoelectric tube all access integrated circuit board, heat conduction
Oil temperature is gathered by temperature sensor, and when heat conduction oil temperature is less than setting, integrated circuit board starts heat-generating pipe heating conduction oil,
When temperature reaches setting, stop heating, when solution is not enough in photoelectric tube measures solution bottle body, integrated circuit board startup sound
Sound alarm, while stopping heat-generating pipe work；The onboard temperature sensor of integrated circuit board is measured to environment temperature, due to collection
It is not the emphasis that the present invention is illustrated into wiring board circuit design matters, its function is only introduced here；Viewing lens, switch, bonnet
The installation of plate is identical with implementation method one, repeats no more here.
After design using implementation method two, realize by the feedback to variation of ambient temperature, more precise control heating
Trip temperature opened loop control is entered in the surface temperature of component, realization to the solution temperature in thermostat, but compared to implementation method one, into
Originally increased.
