Detailed ways

The basic principle of the present invention is to add a fragrance distribution device on the existing television system, the fragrance distribution device is provided with a control module and a fragrance concentration detection probe, after the fragrance concentration detection probe detects the fragrance concentration in the air, the fragrance concentration is judged by the control module Whether the concentration exceeds the preset critical value, if it exceeds, the control module controls the opening and closing of the scent hole to drive the motor to close the scent hole, and calls the OSD menu through the MCU of the TV system, and displays on the screen that the concentration of the fragrance is too high, and the smell hole A closed message to alert the user.

The schematic diagram of the system of the present invention is shown in Figure 1. The fragrance distribution device is connected to the MCU through the control module. Go to the MCU, and the MCU calls the OSD menu to display on the screen according to the information.

Wherein, the structure of the fragrance distribution device is shown in Figure 2, which mainly includes a control module, a fragrance source containing box, a fan and a fragrance distribution hole. When the control module controls the opening of the scent hole, the scent of the scent source contained in the scent source container can be released into the air, and the fan is used to speed up the release of the scent. In addition, the device is also equipped with a drive motor that automatically pops out the fragrance source box, which can automatically eject the box when the fragrance source in the box is not enough, so that the user can replace the fragrance source.

The operating principle of the fragrance emitting device of the present invention is as shown in Figure 3:

1. The user inputs an instruction to start the fragrance emitting device through the remote control or the control panel, and the MCU of the TV system forwards the instruction to the control module of the fragrance emitting device.

2. The control module in the fragrance distribution device controls the driving motor of the fragrance distribution hole to open the distribution hole of the fragrance distribution device to send out fragrance.

3. The fragrance concentration detection probe in the fragrance distribution device detects the fragrance concentration in the air.

4. The control module compares the detection result with the preset fragrance concentration critical value, and judges whether the detected fragrance concentration is greater than the critical value, if yes, go to step 5, otherwise repeat step 4.

5. The control module controls the driving motor of the odor-dispersing hole to close the odor-dispersing hole and stop emitting fragrance.

6. The control module notifies the TV system MCU to stop emitting fragrance, and the TV system MCU invokes the OSD display menu, and displays the information on the screen that the fragrance concentration is too high and the odor-dispersing hole is closed.

In addition to automatically detecting the concentration of fragrance in the air and deciding whether to stop fragrance distribution according to the detection result, the fragrance emitting device of the present invention also has the function of automatically detecting the amount of fragrance source in the fragrance source containing box and deciding whether to remind the user according to the detection result. The function of reinstalling the fragrance source.

Its working principle is shown in Figure 4:

1. The fragrance concentration detection probe of the fragrance distribution device detects the fragrance concentration in the air and sends the detection result to the control module.

2. The control module compares the detection result with the preset reminder value for reminding the user to replace the fragrance source. If the detection result is lower than the reminder value, go to step 3; otherwise, go to step 1.

3. The control module transmits the information to remind the user to replace the fragrance source to the TV MCU, and the MCU calls the OSD menu to remind the user to replace the fragrance source and displays it on the TV screen to remind the user to replace the fragrance source.

4. The fragrance concentration detection probe detects the fragrance concentration in the air and sends the detection result to the control module.

5. The control module compares the detection result with the pre-set pop-up value of the automatic pop-up fragrance source box, if the detection result is lower than the pop-up value, go to step 6; otherwise go to step 5.

6. The control module starts the driving motor for the pop-up of the fragrance source box, and automatically ejects the fragrance source box.

In addition, the fragrance emitting device of the present invention is also provided with a fan for accelerating the fragrance emission, and the fan is used to accelerate the fragrance emission when starting the fragrance emitting device. Its working principle is shown in Figure 5 and mainly includes the following steps:

1. When the fragrance emitting device starts to work, record its working time, and the control module controls the fan to start.

2. The system compares the current time with the time recorded in step 1. If the fragrance emitting device starts working and the current time exceeds the preset time (for example, 60 seconds), go to step 3, otherwise repeat this step.

3. The control module controls the fan to be turned off.
