Hereinafter, with reference to Figure 4 will be described in detail the main circuit of the control system for controlling the operation of the automatic fragrance sprayer according to the present invention.

The main circuit of the control system according to the present invention is a main IC element mounted on the control board 20 to be driven, and has a power supply unit 52 for supplying power for driving the system, and has its own memory and is in charge of control. A microcomputer 54 and a motor driver 56 for receiving a control signal for driving the motor 34 from the microcomputer 54 and generating a signal for driving the motor 34, a current control state and The display unit 58 for displaying the monitoring state of the system to the outside, the setting switch unit 60 for setting the use environment of the control system, and detecting the day and night whether the change in voltage according to the changed resistance value To the illuminance detecting unit 62 which is composed of an illuminance sensor which outputs a detection signal to the microcomputer 54, and the low voltage detecting unit 64 which detects whether the power supplied from the power supply unit 52 is lower than an allowable voltage. Made up .

Hereinafter, each configuration of the control system will be described in more detail.

The power supply unit 52 connects two 1.5V batteries in series to supply power for driving the system.

In this way, the DC power supplied from the power supply unit 52 is supplied to the microcomputer 54 and other elements.

When the volume of the container 40 is about 300ml, the microcomputer 54 is pressed about the injection hole 41 about 2880 times, so when the injection hole 41 of the container 40 is pressed 2800 times or more, the container ( The display unit 58 indicates that replacement of 40 is desired.

In addition, the microcomputer 54 receives the detection signal measured from the illuminance sensor 62 and determines whether the current state is day or night, and the spraying time according to the signal input of the setting switch 60. Set intervals, day and night operations, and 24-hour operation.

At this time, the setting switch unit 60 is a time setting switch 59 consisting of a three-way switch to set the spray interval time in units of 10 minutes / 15 minutes / 30 minutes, and turn off (Turn Off) / It consists of a mode setting switch 61 consisting of three switches to set the day mode / 24 hour mode.

In addition, when the plurality of LEDs or LCDs are used to indicate whether the setting switch unit 60 is set and whether the low voltage is sensed, the display unit 58 may increase the manufacturing cost of the product. It consists of (2 COLOR LED) 51.

At this time, the two-color LED 51 is turned on when the spray interval time is set to 10 minutes according to the setting of the time setting switch 59, the green (RED) is turned to 15 minutes In the case of 30 minutes, the red and green lights are turned on, and the control signal is applied from the microcomputer 54 so that the yellow lights are turned on.

On the other hand, the lighting time of the red / green / yellow is 100ms and this one period is preferably configured to repeat the flashing at intervals of 2 seconds.

In addition, when checking the power supply of the power supply unit 52 by the low voltage detection unit 64, if the 2.7V or less, the red (RED) is turned on and the lighting time is 50ms and one cycle at 1 second intervals It will be configured to repeat the flashing.

When the capacity of the container 40 is 300 ml, the number of times the injection hole 41 is pressed is 2800 times, that is, when the counting number of the microcomputer 54 is 2800 or more, the green light is turned on and the lighting time is 50 ms. And one cycle is configured to repeat the flashing at 1 second intervals.

Therefore, when the capacity of the container 40 is 500ml or less, it is preferable to adjust the counting setting value of the micom 54 by setting it by adjusting it.

In addition, the lighting time and the flashing cycle described above may also be modified according to the designer's intention.

On the other hand, when the user is replaced immediately when the replacement of the container 40, there is a risk that the injection port 41 of the container 40 is immediately operated and sprayed, so the two-color LED of the display unit 58 for a predetermined time after replacement It is also preferable to comprise so that (51) flashes.

In addition, by adding a separate buzzer 66 to turn on the power to generate a warning sound for about 3 to 5 seconds to inform the user to replace the container to be notified that the spray directly into the eyes.

In addition, a separate negative ion generating unit 68 which is operated by receiving power from the power supply unit 52 is further provided to be driven together during the operation of the automatic spraying machine to maximize the effect of air cleaning.

At this time, the negative ion generating unit 68 is configured to operate by receiving a control signal from the microcomputer 54, but the user to selectively operate the negative ion generating function by designing to operate separately from the power supply of the power supply 52 It is also preferable to use.

Hereinafter, the main processing flow of the air freshener control system according to the present invention with reference to Figures 4 and 5 will be described in detail.

When power is supplied from the power supply unit 52 into the system, the system program stored in its own memory of the microcomputer 54 is driven and initialized. At this time, the setting value due to the operation of the setting switch unit 60 is checked.

At this time, when the mode setting switch 61 constituting the setting switch 60 is set to the day mode, the microcomputer 54 is a day / night detection signal generated from the illuminance sensor constituting the illumination sensing unit 62. Will be input to check this. (S102)

Then, it is checked through the low voltage detecting unit 64 whether or not the power currently supplied from the power supply unit 52 is equal to or greater than the allowable voltage of 2.7 V. (s104).

The microcomputer 54 which checks the state of the current system as a whole, displays such a state through the two-color LED 51 of the display unit 58 (s106).

As a result of checking the overall system as described above, it is checked whether all the fragrance injection conditions are satisfied.

As a result of the check, for example, the mode setting switch 61 is set to the day mode, but when it is night, the microcomputer 54 does not apply the control signal for the operation of the motor 34 to the motor driver 56. The motor 34 is stopped. (S110)

As a result of checking the system as described above, when all the conditions for the injection are satisfied, the microcomputer 54 sets the forward rotation time of the motor 34 for pressing the injection port 41 of the container 40 (s112). Counting for pressing the current injection port 41 is performed (s114).

As described above, the microcomputer 54 applies a control signal for forward rotation to the motor driver 56 after counting, and accordingly, the motor 34 rotates forward to drive the drive gear 32 provided in the motor drive shaft. Thereby driving the first driven gear 33a and thereby driving the second driven gear 33b geared to the first driven gear 33a 'which is integrally interlocked with the first driven gear 33a. The pusher 31 which is driven and coupled to the second driven gear 33b 'linked with the second driven gear 33b is rotated about one side (ie, the first driven shaft gear). The injection port 41 of the upper end of the container 40 is pressed and directed. (S116)

At this time, the microcomputer 54 checks the application time of the control signal for forward rotation applied to the motor driver 56 and checks whether the motor has been driven for the set time. When the control signal for forward rotation is applied to 34 and the set time is satisfied, the operation of the motor 34 is stopped.

When the set time is satisfied and the forward rotation of the motor 34 stops, the microcomputer 54 sets the reverse rotation time of the motor 34 to return the injection port 41 of the container 40 to its original state ( S120, when the control signal for the reverse rotation is applied to the motor driving unit 56, the motor 34 is to reverse rotation. Accordingly, the container 40 is driven by the driving gear 32, the first and second driven gears 33a and b, and the first and second driven shaft gears 33a ′ 33b ′ by the reverse rotation driving of the motor 34. The pressing hole 31 holding down the injection port 41 of is returned to its original position by the gear movement in the opposite direction, and is returned to the upper side.

At this time, the microcomputer 54 checks whether the motor 34 is driven during the set time by checking the application time of the control signal for reverse rotation applied to the motor driver 56 and continues if the set time is not reached. By applying the control signal for the reverse rotation to the motor and the set time is satisfied, the operation of the motor 34 is stopped (s124).

Although the embodiments of the present invention have been described in detail as described above, the scope of the present invention is not limited thereto, and the scope of the present invention extends to the range substantially equivalent to one embodiment of the present invention.

As can be seen from the above description, according to the present invention, the injection time interval set through the time setting switch and the day mode / 24 hour mode set through the mode setting switch, and whether the power supplied from the current power supply is external In order to enable the user of the fragrance spraying device to immediately identify the abnormal state and the cause thereof, it is possible to promptly change the container and replace the battery constituting the power supply in advance.

In addition, to display various functions as described above, by using only one two-color LED without the need to use LCD or multiple LEDs, it is displayed to the user by changing the flashing cycle during normal operation and the flashing cycle such as replacement time. It will also have the effect of lowering the manufacturing cost of the manufacturer of the product.
