Description

Double-temperature and automatic timing control for decocting medicinal herbs

This controller is to be used for controlling a kind of electronic installation that electric energy heats fried Chinese medicine decoction or Other Drinks automatically, is quasiconductor thermometric, Digital Logic control, time base circuit timing in the electronic technology, and contactless gate-controlled switch etc. are planted an integrated application of technology.

The present invention is extended in conjunction with the electric rangette in modern times, the method for the various beverages of electric cup boiling by traditional artificial decocting herb decoction.No matter be which kind of decocting method, all need the artificial decoction process that monitors unavoidably, careless slightly, make decocting time long, how can cause into the sources of the disaster such as medicine is scrapped, vessel damage.Especially in today of the labour of social character, under the situation in short supply day by day of Chinese medicine source, be necessary to propose a kind of easy controller that decocts decoction automatically, the present invention does for this reason.

Task of the present invention is to make a kind of simple in structurely, easy for operation, has plesichronous, two temperature heating, can monitor the decoction temperature voluntarily, controls the domestic electronic controller of characteristics such as decoction program automatically.It can make the hand labor simplification of soup stocks such as decocting herb, especially can save manual observation administrative time, increase work efficiency, therefore can be widely used in the generation visitor processing decoction of each hospital, each shop of Chinese medicines etc., and huge numbers of families are used for decocting herb decoction or various beverage voluntarily.Only need to open decocting method (" raging fire " or " slow fire " earlier earlier) the conversion gauge tap position at place during use according to Chinese physician, the pharmacist of Chinese medicine, set up regularly knob by required decocting time, with common electric cup or use the electric furnace grug feeding jar, add entry and medicine (or material), on the outer wall of cup (jar), post temperature measuring head (also can not must thermometric again, direct in due course hand push button switch starting timing circuit), plug plugs in, circuit promptly enters duty automatically, and display demonstrates " raging fire " or " slow fire " heated condition at that time simultaneously.

The method of solution task is: with a TTL four or two NAND gate integrated circuits as logic control and overtemperature protection; Form the two-stage mono-stable timing circuit with a FX556 dual time-base ic (555 single time base circuits of also available two various other models); Two-way and one-way SCR selects job order to realize that two temperature decoct by gauge tap and different heating mode (i.e. elder generation " raging fire " back " slow fire " or elder generation " slow fire " back " raging fire " with one respectively, must boil fast one, two minute with " raging fire " as the general solution medicine administered to bring out the cold, general tonic is then used " raging fire " to boil reuse after several minutes " slow fire " earlier and was fried in shallow oil slowly one, 20 minute etc., by different medicines, prescription or follow the doctor's advice and decide); BE roped party with audion becomes temperature measurement circuit, and temperature signal amplifies as the NAND gate input signal through two audions; Extract circuit work power etc. by methods such as capacitive reactance blood pressure lowering halfwave rectifier.

Concrete structure of the present invention is provided by following embodiment and electrical principle circuit (accompanying drawing) thereof.The operation principle of this controller is:

After the controller accessory power outlet was plugged load (but the following electric furnace of the design's circuit adapted 1KW or electric cup), again attaching plug inserted power supply, 220 volts of electric mains were through capacitor C ₁(1.5uF/400V～) and bleeder resistance R ₁(220K Ω) blood pressure lowering is through diode D ₁, D ₂(1N4004) halfwave rectifier is by capacitor C ₂(1000uF/25V) filtering, diode D ₃(2CW21E) voltage stabilizing obtains about 9 volts circuit work power.9 volts of power supplys are through diode D ₄(2CW11) blood pressure lowering obtains about 5 volts of voltages as thermometric and logic circuit working power, C ₃(330uF/16V) as 5 volts of power filters.

By silicon semiconductor pipe T ₃(3DG6 etc.) and current-limiting resistance R ₂(150K Ω) forms temperature measuring head, is serially connected with T ₄(3CG21 etc.) and T ₅Form the thermometric loop between (3DG6 etc.) base stage, when the rising of tested (decoction) temperature, the thermometric electric current increases, and makes T ₄Collector potential raises, and T ₅Collector potential reduces, and action potential separately is respectively by R ₃, R ₄(1K Ω) and W ₁, W ₂(4.7K Ω semifixed resistor) set up.

Powering at the beginning, because R ₅(10K Ω) and C ₄Effect (10uF/10V) makes the door 3 output high level of TTL four or two NAND gate (T095), is low level (about 0.5V) by 4 outfans of door 3, the door 4 basic rest-set flip-flops of forming, so diode D ₇(2CW15) with audion T ₇(3CG23 etc.) all conductings are by miniature 2 * 2 toggle switches of mode of heating gauge tap K() select (drawn circuit is by " raging fire " back " slow fire " action earlier among the figure) to make the corresponding driving resistance R ₁₁, R ₁₂(1/2 W160 Ω), demonstration LED ₁, LED ₂And R ₁₃, R ₁₂(330 Ω) obtains electric current, noncontacting switch device T ₁(bidirectional triode thyristors of the various models of 5A/400V) and T ₂(one-way SCRs of the various models of 3A/400V) corresponding conducting that is triggered, thus make load (electric cup) obtain full merit or half merit and realize simulating the raging fire or the slow fire of decocting for Chinese herbal medicine.As not needing temperature self check automatic control, can not connect temperature measuring head, and various miniature open type press buttones of manual operation press button AN(in due course) with starting plesichronous circuit.

The plesichronous circuit is by IC ₂(dual time-base ic of model such as FX556 or single time-base integrated circuit of two models such as FX555), and by R ₇, R ₉(20K Ω) two input resistances.C ₅, C ₇The input circuit that (the common electric capacity of the various models of 0.1 μ F) is formed is by C ₆, C ₉The compensating circuit of (the various electric capacity of 0.01 μ F) is by R ₈, R ₁₀(2K Ω), W ₃, W ₄(2M Ω semifixed resistor) and C ₈, C ₁₀The timing range that (470 μ F/16V) forms is respectively constituted by two mono-stable timing circuits of one second to 14 minutes.

Along with dut temperature is elevated to when closing on 100 ℃, T ₄Collector potential is elevated to the action potential of setting, promptly equals the threshold level (being about 1.6V) of rest-set flip-flop control gate (door 1), door 1 output low level that is opened, and door 4 is closed output high level (about 3V), makes D ₆, T ₇End, door 3 output low levels that are opened are by coupling capacitance C ₅Provide the triggering signal of a negative saltus step to first timer input (6 feet of dual time base sheet), thereby finishing the initial heating period entered automatically by the plesichronous of setting-up time two temperature heating periods.After mono-stable timing circuit is triggered, press TW ≈ 1.1RC(R ₁=W ₃+ R ₈, R _II=W ₄+ R ₁₀, C=C ₈=C ₁₀) cycle time by outfan (first timer is 5 feet, and second timer is 9 feet) output high level with the relay drive current, realize that plesichronous decocts function.D among the figure ₈, D ₉, D ₁₀(2AK20) be isolating diode.First timer regularly finishes, and its outfan is returned to low level from the negative saltus step of high level, and this negative skip signal is by C ₇Coupling changed for the second timing heating period over to automatically as the triggering signal of second timer, had so just realized plesichronous.

After dut temperature surpasses 100 ℃, T ₅Collector potential moves closer to and is lower than the action potential of its setting, promptly is lower than the threshold level of door 2, makes door 2 close the output high level, by R ₆(510 Ω) makes T ₆The drive current that each outfan provides is pulled away in (3DG12 etc.) conducting, to close each thyristor, stops automatically decocting, thereby prevents the various disasters that cause because of " water is dried " effectively.By T ₆Colelctor electrode adds two diode D respectively ₅, D ₆(2AK20) as interlock protection, be not damaged to guarantee guard mode, reset unless power on again behind the entire controller disengaging power supply.But as long as dut temperature surpasses 100 ℃, circuit still can enter guard mode work, is unlikely to lose overheat protective function repeatedly because of power supply status.
