Detailed description of the invention

Below in conjunction with accompanying drawing further description embodiment and operation principle:

Embodiment one, seeing Fig. 1 is a water warming blanket main frame potentiometer temperature-control circuit, the temperature control of integrated circuit composition Operation principle processed, power circuit is by electric capacity C1 resistance R1 blood pressure lowering, rectifier bridge stack UR rectification, filter capacitor C2 and stabilivolt D1 Composition；Temperature sensing circuit is by transistor VT, resistor R2～R3, potentiometer RP1, capacitor C3, the integrated electricity of operational amplifier Road IC1 forms；Control circuit by float switch LS, resistor R4-R5, optocoupler U1, controllable silicon T2, add heat pipe RL2, temperature switch ST1, water pump RL1 form；Indicating circuit is made up of hydropenia display lamp HL1, burner on light HL2.

Alternating current 220V voltage is after electric capacity C1 resistance R1 blood pressure lowering, UR rectification, C2 filtering, D1 voltage stabilizing, for temperature detection control Circuit provides+6V working power.

VT, as temperature sensor (also the critesistor of usable temp coefficient replaces), is used for detecting the temperature of main frame water tank Degree, LS detects water level in main frame water tank as water level switch, when in main frame water tank anhydrous time float switch LS fall to disconnecting, collection Become IC circuit 14 foot non-transformers do not work, at this moment due to water pump RL1 be by temperature detect switch (TDS) ST1 control work, water temperature reaches not The condition opened to temperature detect switch (TDS) ST1, water pump RL1 also quits work, and floats when injecting water float switch LS in main frame water tank Conducting, 4 foot energising work of IC 1, the conducting internal resistance of VT changes along with the change of temperature, when temperature is raised, The conducting internal resistance of VT declines, and upon a drop in temperature, the conducting internal resistance of VT increases, when main frame water the temperature inside the box is less than RP1 setting During temperature value (resistance value), the conducting internal resistance of VT is relatively big, makes the 2 foot voltages (inverting input) of IC1 less than (the positive input of 3 feet End) voltage, the 1 foot output high level of IC1, V1 saturation conduction, optocoupler simultaneously turns on controllable silicon T2 work, adds heat pipe RL2 energising Start to heat, start working to uniform temperature (temperature switch ST1 sets 35 degree) temperature switch ST1 energising water pump；Along with temperature Rising, the internal resistance of VT is gradually reduced, and the 2 foot voltages of IC1 also gradually rise.When the main frame water tank temperature setting temperature more than RP1 When spending, the 1 foot output low level of IC1, V1 end, optocoupler U1 does not works, RL2 power-off and stop heating.With aft engine water tank temperature Degree starts slowly to decline, and when temperature is down to below the design temperature of RP1,1 foot of IC1 exports again high level, and V1 is the most saturated to be led Logical, optocoupler U1 works, and adds heat pipe RL2 and is energized again work.Above work process is gone round and begun again, and in making main frame water tank, temperature constant is The design temperature (controlling temperature error is ± 1 DEG C) of RP1, potentiometer RP1 can put the graduated knob of band and graduated disc, is adjusting During joint very clear, this embodiment integrated circuit use LM324 amplifier, also can use 555 time base circuit OR circuits or its Its integrated circuit.

Embodiment two, sees Fig. 2, and as homoiothermic is worked with embodiment one, different heres are that the temperature controlling water pump is opened Pass ST1 has changed the triggering foot of controllable silicon T1, controllable silicon T1 into and has been triggered by optocoupler U2, when float switch LS anhydrous in main frame water tank breaks Opening, 4 feet of IC 1 and optocoupler U2 must not be electric, only in main frame water tank after water filling float switch LS work, and integrated electricity 4 feet of road IC1 and optocoupler U2 obtain electric work, and controllable silicon T1 works, pump working；IC 1 obtains electric work process and reality As executing example one.

Embodiment three, sees Fig. 3, a water warming blanket main frame potentiometer temperature-control circuit, and audion composition temperature control triggers can Control silicon circuit principle, temperature sensor RT, potentiometer RP, audion V2, audion V3 composition temperature control triggers circuit, control circuit By float switch LS, controllable silicon T2, add heat pipe RL2, temperature switch ST1, water pump RL1 form；Indicating circuit is by hydropenia display lamp HL1, burner on light HL2 form, LED 3 and LED 4 Opposite direction connection, it is provided that 2.3V alternating current Pressure；RT, as temperature sensor (also the audion of usable temp coefficient replaces), is used for detecting the temperature of main frame water tank, LS conduct Water level switch detects water level in main frame water tank, when in main frame water tank anhydrous time float switch LS fall to disconnecting, audion V2, three Pole pipe V3 non-transformer does not works, at this moment due to water pump RL1 be by temperature detect switch (TDS) ST1 control work, water temperature does not reaches temperature control and opens Closing the condition that ST1 opens, water pump RL1 also quits work, and floats conducting when injecting water float switch LS in main frame water tank, three poles Pipe V2, audion V3 obtain electric work, and temperature sensor both end voltage URT is more than 0.6V, and V2 conducting during exchange positive half-wave, through two poles Pipe D2 triggers, V3 conducting during exchange negative half-wave, triggers through diode D3 negative sense, and T2 turns on, and makes to add heat pipe RL2 heating, now leads Machine water the temperature inside the box raises, and starts working to uniform temperature (temperature switch ST1 sets 35 degree) temperature switch ST1 energising water pump, Temperature is increased to a certain numerical value, adjusts potentiometer RP2, makes URT be less than 0.6V, and audion ends, and T2 is not turned on, thus realizes control The purpose of temperature processed, above work process goes round and begins again, and the design temperature making temperature constant in main frame water tank be RP1 (controls temperature Degree error is ± 1 DEG C), potentiometer RP1 can put the graduated knob of band and graduated disc, very clear when regulation.

Embodiment four, sees Fig. 4, and as homoiothermic is worked with embodiment three, different heres are that the temperature controlling water pump is opened Close ST1 to have changed the triggering foot of controllable silicon T1, controllable silicon T1 into and powered by float switch LS and directly trigger, when anhydrous in main frame water tank Float switch LS disconnects, and controllable silicon T1 triggers foot and audion V2, V3 must not be electric, only water filling float switch in main frame water tank After LS work, controllable silicon T1 triggers foot and audion V2, V3 obtain electric work, and controllable silicon T1 works, pump working；Audion V2, V3 obtains electric work process as embodiment three.

This utility model is not limited to above-mentioned embodiment, uses identical with this utility model above-described embodiment or approximation Structure, and the method obtained, all within protection domain of the present utility model.
