Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a chemical dispersion device that forcibly disperses chemicals such as fragrances and deodorizers by rotating a fan, and more specifically relates to a chemical dispersing device that forcibly disperses chemicals such as fragrances and deodorizers by rotating a fan. This paper relates to an intermittent-acting drug dispenser that is controlled intermittently.

[Prior Art] Conventionally, as a drug emitting device, a drug emitting device is known that strongly emit a drug by continuously rotating a motor without stopping the motor.

It also detects the illuminance in the room and continuously rotates the motor while it is bright! There are also known drug emitters that stop the motor when it gets dark.

[Problem to be solved by the invention 1] The former type of conventional technology has a motor that rotates continuously without stopping, resulting in extremely short battery life. There was a lot of wasteful consumption of drugs.

In addition, the latter type has the advantage that it stops the motor when the room is dark, such as late at night, thereby reducing wasteful consumption of the drug, but it rotates continuously during bright light. There was a drawback that medicine was wasted when no one was in the room for a long time.

[Means for Solving the Problems] In order to solve the above-mentioned drawbacks, the intermittent action type drug dispensing device according to the first invention rotates the motor for a certain period of time, then stops it, and repeats these on/off operations. It is characterized by being equipped with an intermittent control circuit.

Further, the intermittent action type drug dispensing device according to the second invention is characterized in that an illuminance sensing circuit is provided upstream of the intermittent control circuit to stop the motor when it is dark and to operate it when it is bright.

[Function] According to the first invention, since the motor can be controlled intermittently, the battery does not run out while the machine is stopped, which extends the life of the 4J battery, and at the same time prevents wasteful consumption of medicine. .

In addition, according to the second invention, the illuminance sensing circuit stops the motor when the room is dark at night or when the lights are turned off, and performs continuous intermittent control similar to the above when it is bright, so the motor stops at IIa. Also, due to the intermittent stoppage during the daylight hours, the lifespan of the G dry battery can be prolonged and the waste of chemicals can be suppressed, and an effective dispersion function of air fresheners etc. can be realized.

[Example] Hereinafter, an example of the intermittent music emitting device according to the present invention will be described in detail with reference to the drawings.

FIG. 1 is a block diagram of an intermittent action type drug emitting device according to the present invention. DES is a DC power source such as a dry battery, and the intermittent control circuit C is driven by this DC power source DES.

Furthermore, the rotation and stopping of the motor M is controlled by the function of this control circuit C. Liquid medicine 10 is in the medicine container 10C.
e is filled, and this drug 10e has a volume of 10c.
It is sucked up by capillary action from the glass m-fiber 10d built in the cylindrical part 10b and released from the volatilization surface 10a provided on the cylindrical part 10b. A fan FA is installed facing the volatilization surface 10a, and the recirculating air of the fan FA forces the chemical 10e to evaporate from the volatilization surface 10a.

FIG. 2 is a detailed circuit diagram of the intermittent control circuit C.

The intermittent control circuit C is a DC power supply DES installed externally.
, an oscillation circuit PG, a frequency division circuit CC that frequency divides the oscillation pulse of this oscillation circuit, a start control circuit MC that starts the motor by the output pulse of this frequency division circuit CC, and a stop circuit that stops the motor. It is composed of a control circuit RTC, a set circuit RC that resets the states of these circuits, and an illuminance sensing circuit LS that detects the ambient illuminance.

Each partial circuit will be explained below according to the drawings.

Oscillation circuit PG is Punto gate NΔNDI ・NAND2
・NAND3, resistor R3/R4, and capacitor-01
The oscillation frequency fo is the time constant R4C.
Determined by I. The frequency dividing circuit CC is composed of n JK flip-flop circuits JKFF+ to JKFFrl.

The stop F control circuit RTC is l・Run sister T6・``7
and inverter IN, resistor R6, [)7, and capacitor.
-C3. The starting control circuit MC is composed of transistors T3, T4, T5, a resistor R5, and a conductor circuit C2. The illuminance detection circuit LS includes a photoconductive element CdS, a 1-run sister T1, T2, and a resistor R1.
・Constructed by R2.

The operating principle of each partial circuit will be explained below. In the oscillation circuit PG, the terminal 2 is rHJ and the terminal 1 is rLJ at the moment the power switch SW is closed. Here, "T1" indicates a high potential state, rLJ indicates a low potential state,
Similarly, in the following, the angle is 16 degrees. Therefore, the terminal 6 becomes "T1", the end T4 becomes rLJ, and the terminal 5 becomes rHJ. Therefore, the capacitor C1 is gradually charged, and when the potential of the terminal 3 reaches a certain value, the potential of the terminal 1 is inverted to rHJ. That is, terminal 6 becomes "L", terminal 4 becomes "H", and terminal 5 becomes rLJ. Here, since the terminal 5 has become rLJ, the terminal G+ gradually starts discharging, and when the potential of the terminal 3 becomes smaller than the value, the terminal 1 becomes "resistance".

In the oscillator circuit PG, a pulse of frequency fO is generated from the terminal 6 by repeating the above operation. Furthermore, by appropriately setting the capacity of the resistor R4 or the capacitor C1, the frequency "O" can be arbitrarily selected.

In the frequency dividing circuit CC, each flip-flop circuit operates as a T flip-flop circuit by keeping its J terminal and terminal at ")". That is, if we talk about the JK flip 70 tube circuit JKFF+, the output is inverted at the rising edge of the input pulse. In other words, if the output becomes rHJ at the falling edge of a certain pulse, the output becomes rLJ at the falling edge of the next pulse. This operation divides the frequency of the output pulse into rO/2. By using n similar flip-flop circuits, the frequency of the output pulse of the n1% flip-flop circuit JKFFn becomes fo/2", and the input frequency of the frequency divider circuit "0 is divided into 1/24". Further, frequency division by an arbitrary number is also possible by manually inputting the output from an appropriate JK flip-flop circuit to a NAND game.

Furthermore, by increasing or decreasing the number n of JK flip-flop circuits included in the frequency dividing circuit, output pulses can be obtained depending on the purpose.

In the stop control circuit RTC, the frequency divider circuit CC output is r l-I
When the voltage becomes J, the 1st resistor T6 turns on, and the capacitor C3 is charged through the resistor R6.
t Begins. That is, the potential of terminal C gradually rises, and this potential of C is outputted as an output to the reset circuit RC.

In the reset circuit RC, when the output of the startup control circuit RTC reaches a certain value of potential (the time given by the resistor R3 and the capacitor 03), the output of the OR circuit OR becomes rI-I
J and outputs a reset j~ signal to the frequency divider circuit CC. Also, if you wish to reset the switch 51
4R can be used to serve this purpose.

With the above stop control circuit RT C and reset circuit RC,
The output of the frequency dividing circuit CC is obtained as a pulse having a time width determined by the quantitative constants of the resistor R6 and the capacitor C3 included in the stop control circuit RTC. In addition, when the output of the frequency dividing circuit becomes "L", the power accumulated in the capacitor C3 connected to the stop control circuit RTC is
It is discharged through the inverter IN, the transistor T7 which is in the off state, and the resistor R7, and the stop control circuit R
TC itself is also reset.

In the startup control circuit MC, while this output pulse is in the rHJ state by the output of the frequency divider circuit CC as described above,
Transistor T3 is turned on, and capacitor C2 is charged via resistor R9. When the potential of terminal U reaches a certain value, transistors T4 and T5 are turned on, and motor M starts rotating.

When the output of the frequency dividing circuit CC is inverted to rLJ, the 1-range screen T3 is turned off, and the power accumulated in the capacitor C2 by this time is transferred to the resistor Rs and the transistor T.
Although it is discharged through T5, the 1-run sister T4 and 5 remain on and the motor M continues to rotate until the potential at the terminal U falls below a certain value. Then, when the potential of the terminal U becomes less than a certain value, the 1-run sisters T4 and T5 turn off, and the t-termer M stops. Therefore, the rotation time of the motor M is the resistance R
5 and the time constant of capacitor 02.

In the illuminance detection circuit [S, a voltage divided by the photoconductive element CdS and the resistor R1 is applied to the base of the transistor T2, and as the illuminance increases, the resistance value of the photoconductive element CdS decreases and the base voltage is reached. When the value is exceeded, the transistor T
2.T1 is turned on, and the entire intermittent control circuit starts operating. Conversely, when the illuminance is low and the resistance value of the photoconductive element CdS increases, the base voltage of the transistor 12 decreases, and when it becomes below a certain value, the base voltage of the transistor T2 increases.
1 is turned off, and the entire l17i integrated control circuit is turned off.

Figure 3 is a time chart at each point in Figure 2,
The above explanation is shown in an easy-to-understand manner.

At time [1], when the output of the point A of the frequency divider circuit CC is reversed from rHJ to rLJ, the output of the point B becomes r)-IJ, and the capacitor C2 of the starting 4111 circuit MC is charged according to the time constant relationship of the resistor R9. .

As a result of this charging, point U becomes rHJ and motor M starts rotating.

At the same time, since the output of the point B becomes rHJ, the capacitor C3 of the stop control circuit RTC is charged according to the time constant relationship with the resistor R6, after the charging time Tc, that is, at time 1.
2, point C becomes "T1", and the OR circuit OR becomes r
l-I J, reset the frequency dividing circuit CC, and reset the stop control circuit RTC after the time constant of capacitor', 1-C3 and resistor R7. let

That is, when the point B becomes "1-" at time 1°, the transistor T3 is turned off, and the capacitor 02 stops discharging after a certain time r1 time Tr of the resistor R5, and at time t3, the motor M h' p? Stop.

After the time TS by the frequency dividing circuit CC, that is, the time! Repeat the operations described in 4.

Therefore, the motor M rotates for a rotation time Tm and stops for a stop time Ts, and by repeating these on-off operations, it periodically repeats the release of fragrance and deodorization, and at the same time prolongs the life of the dry battery. This is what we will achieve.

By appropriately selecting the rotation time Tll+ and the stop time TS, appropriate fragrance, deodorization, etc. can be achieved.

[Effects of the Invention] As detailed above, the present invention reduces waste of medicine and batteries by rotating and stopping the heater at regular intervals, and furthermore, by providing an illuminance detection circuit, human When it is dark, when there is no possibility that there will be any
This further reduces wastage of chemicals and batteries, and is of practical use.
``This is a very basic invention.
