Abstract
The utility model relates to a liquid constant temperature heating vaporing apparatus, which is composed of power transfer, a temperature sensor, an electronic control circuit, and a heater; the liquid constant temperature heating vaporing apparatus is characterized in that the electronic control circuit is composed of a comparator, an NAND gate circuit, and a switch circuit. The liquid constant temperature heating vaporing apparatus uses the electronic control circuit to control heating value of the heater in constant temperature, and as a result, the gas discharge can be quantitatively controlled. The liquid constant temperature heating vaporing apparatus has the advantages of simple structure, convenient operation, high safety, and low cost, and can be used for various applications such as the indoor air perfuming for deodorization, artificial flowers perfuming, smell expelling mosquito, liquid medicine vaporing, etc.
Description
This utility model relates to a kind of Electronic Control thermostat, particularly a kind of liquid constant temperature heating and evaporating unit.
The general fragrant deodorization of indoor air, Artificial flowers and plants, flowerpot are fragrant, abnormal smells from the patient anophelifuge and medical medicinal liquid fumigation etc., be liquid source to be become gas could use, become the in the past room temperatures that adopt of gas from liquid volatilizees or the direct heating evaporation naturally, its shortcoming is that volatile quantity or evaporation capacity are difficult to grasp, and effect also is difficult to reach optimum state.
The purpose of this utility model is to overcome above-mentioned weak point and a kind of liquid constant temperature heating and evaporating unit is provided, and it adopts electronic control circuit, the caloric value of thermostatic control heating element, thus quantitatively control the gas purging amount.This apparatus structure is simple, esy to use, safe and reliable, with low cost, is fit to various occasions and uses.
The purpose of this utility model can reach by following measure: this device is made up of power conversion, temperature sensor, electronic control circuit, heating element, it is characterized in that electronic control circuit is made up of comparator, NAND gate circuit, on-off circuit, comparator is by operational amplifier A
1A
2Form, NAND gate circuit is made up of an ic chip.
Accompanying drawing is a liquid constant temperature heating and evaporating unit schematic circuit.
This utility model embodiment is described in further detail below in conjunction with accompanying drawing:
Power conversion is to be that the 12V direct current is powered to this device with the 220V civil power through transformator conversion rectification.Temperature sensor is 500 Ω thermo-sensitive resistors, and its resistance varies with temperature and changes, and the resistance wire of it and heating element goes between respectively and places in the same container, and container fills liquid to be evaporated.
Electronic control circuit is made up of comparator, NAND gate circuit, on-off circuit, and wherein comparator is by A
1A
2Operational amplifier (MC448) is formed, and regulates RP
1And RP
2Variable resistance is scalable A
1A
2Duty.Just preset this device thermostatic control scope, as 50-60 ℃; NAND gate circuit is made up of an ic chip (CD4011), and its outfan is connected on on-off circuit (3DD15A) base stage, and the resistance wire of heating element is the load of on-off circuit.
The electronic control circuit operation principle is as shown in drawings: initial period is regulated RP
1Variable resistance makes comparator A
13 foot current potentials be higher than 2 foot current potentials, promptly its 1 foot is output as high level, the feedback current potential of 2 feet of IC is a low level, then 3 of IC, 5 feet are low level; Meanwhile, regulate RP
2Variable resistance makes comparator A
2The voltage of 5 feet be higher than 6 foot voltage, then A
2 Outfan 4 feet are low level, 6 feet that are IC are low level, 5,6 feet of IC are low level, therefore IC outfan 4 feet are high level, and this high level is added on the base stage of on-off circuit, impels the rapid conducting of audion 3DD15A, its load current flow through heating element resistance wire and generate heat, make that temperature constantly rises in the container, its resistance of thermo-sensitive resistor in the container descends with the rising of temperature, when the temperature resistance of thermo-sensitive resistor that rises when surpassing 60 ℃ of preset temperatures descends and senses comparator A
12 feet be high level, A
11 foot and 1 foot of IC be low level, 2 feet of feedback voltage IC are high level, outfan 4 feet of IC are low level, audion ends rapidly, and load current is zero, and resistance wire stops heating, temperature descends naturally in the container, and the thermo-sensitive resistor resistance descends with temperature and rises, and feeds back to comparator A
1A
2, when dropping to 50 ℃, as the conducting heating again of above-mentioned audion, circulation so repeatedly, the temperature in the container changes in presetting 50--60 ℃ of constant temperature scope all the time, and the liquid in the container can quantitatively evaporation in the constant temperature scope.
This utility model adopts electronic control circuit, the thermostatic control caloric value, thus quantitatively control evaporation capacity.The constant temperature scope can be according to different liquids, and different purposes preset, and changes the drawback that liquid volatilizees naturally or direct heating evaporates in the past, is fit to the fragrant deodorization of various indoor airs, and the Artificial flowers and plants flowerpot is fragrant, abnormal smells from the patient anophelifuge medical treatment medicinal liquid fumigation or the like purposes.
