When the detection signal is received from the human body sensor 170 by the human body in the front door area, the controller 180 outputs the stop request information such as “stop” or “stop” through the speaker 173 as audio sound. Warning sound such as a siren sound is output, and the alarm light 175 flashes a red light to output the alarm information to take out the mask to the user to go out.

In addition, the controller 180 receives alarm information through the speaker 173 and the alarm lamp 175, as described above, when the detection signal by the human body in the entrance area is received from the human body sensor 170 as described above. At the same time as the output, when the emission color of the pollution degree display unit 144 detected from the color sensor 150 is yellow light (poor pollution level) or red light (poor pollution level), as shown in Figure 2, the mask container portion 120 ) Rotates the take-up motor 131 in one direction so as to descend to the mask providing height.

Accordingly, after recognizing the alarm information output from the speaker 173 and the alarm lamp 175, the user can take out the disposable mask 124 from the mask container part 120 lowered to the mask providing height to go out. .

On the other hand, as shown in Figure 2, the control unit 180, when the predetermined time (preferably 20-30 seconds) has elapsed in the state where the mask container unit 120 is lowered to the mask providing height, the mask container unit 120 Is raised again to control the rotation of the winding motor 131 in the reverse direction so that it is drawn into the main body 101.

However, the control unit 180 rotates the take-up motor 131 in the reverse direction, and ascending the mask container unit 120 to the original state to be introduced into the main body unit 101 is configured to be executed when a predetermined time elapses. Although not limited thereto, a touch sensor (not shown) may be installed at one side of the main body unit 101 or the mask container unit 120 so that the user touches the touch sensor (not shown) to control the controller 180. ) Rotates the take-up motor 131 in the reverse direction so that the mask container 120 is raised to be drawn into the main body 101. In addition, the control unit 180 voices such as 'Good bye' and 'Good night' through the speaker 173 after a predetermined time (preferably after 0.5 to 1 second) when the touch sensor (not shown) touches. May be configured to output comments.

On the other hand, the controller 180 of the present invention may be configured to further include a wireless communication unit 182, the current area identification unit 183, the fine dust information search unit 184 and the data comparison unit 185.

In the present invention, the wireless communication unit 182, the current area identification unit 183, the fine dust information retrieval unit 184, and the data comparison unit 185 may be configured as hardware or software, or a combination of hardware and software.

The wireless communication unit 182 is made of a module that can be connected to the wired and wireless Internet so that the controller 180 can be connected to the wired and wireless Internet network.

The current area identification unit 183 is configured with a GPS module, it is configured to check the area information installed the mask supply device 100.

The fine dust information retrieval unit 184 accesses the air pollution real-time disclosure system of the Korea Environmental Management Corporation website through the wireless communication unit 182, and fine dust of the area corresponding to the area information obtained by the current area confirmation unit 183. Obtain concentration range information (contamination level information) according to the concentration. At this time, the concentration range information is displayed in blue when the fine dust concentration is 0 ~ 30㎍ / m³ (good pollution level), and displayed in green when the fine dust concentration 31 ~ 80㎍ / m³ (normal pollution level), fine If the dust concentration is 81 ~ 150㎍ / m³ (poor pollution level), it is yellow. If the dust concentration is 151㎍ / m³ (poor pollution level), it is marked red.

The pollution level determination unit 185 acquires the emission color of the pollution degree display unit 144 detected by the color sensor 150 and the air pollution degree of the website of the Environmental Management Corporation acquired by the fine dust information retrieval unit 184. By checking the color of the local concentration range information, if at least red or yellow is included, the bobbin driving signal may be output to the controller 180, the controller 180 receives the detection signal from the human body sensor 170 When the pollution level determination unit 185 receives the bobbin driving signal, the winding motor 131 is rotated in one direction to control the mask container 120 to descend to the mask providing height as shown in FIG. 2. Can be.

For example, the pollution level determination unit 185 is a blue light emitted from the pollution degree display unit 144 detected by the color sensor 150, and the color of the concentration range information of the corresponding region detected by the fine dust information search unit 184. Even if it is yellow, the bobbin driving signal is output to the controller 180 so that the mask container 120 is lowered to provide a mask, and the emission color of the pollution degree display unit 144 detected by the color sensor 150 is green light or blue light. When the color of the concentration range information of the region searched by the fine dust information search unit 184 is green or blue, the bobbin driving signal is not output to the controller 180.

That is, the fine dust concentration measured by the fine dust measuring unit 140 and the air pollution of the website of the Environmental Management Corporation website may be different from the fine dust concentration of the region provided by the real-time disclosure system, the fine dust measuring unit 140 or the Environmental Management Corporation Web Air pollution of the site If the pollution level is at only one of the fine dust concentration disclosed in the real-time disclosure system is a bad level (yellow) or very bad level (red), the mask container 120 is lowered to the mask providing height by the user This is to get a mask and go out.

While the invention has been shown and described in connection with preferred embodiments for illustrating the principles of the invention, the invention is not limited to the configuration and operation as such is illustrated and described. Rather, those skilled in the art will appreciate that many changes and modifications can be made to the present invention without departing from the spirit and scope of the appended claims.
