The controller 22 controls the operation of the fan 12 according to the number of people fed back by the personnel identification sensor 23, thereby realizing intelligent control. At the same time, the controller 22 feeds back the received information to the cloud server 30 in real time for processing, so as to facilitate the subsequent overall control of users, environmental air quality, etc.
[0030] like Figures 1 to 3As described, in the present embodiment, the air purifier host 10 includes a shell 11 and a fan 12 rotatably connected to the shell 11; the control component 20 includes a main board 21, a controller 22 and a plurality of personnel recognition sensors 23, the main board 21 and the personnel recognition sensors 23 are both installed in the shell 11, the controller 22 is electrically connected to the main board 21, and the fan 12, the personnel recognition sensor 23 and the cloud server 30 are all connected to the controller 22 by signal; each personnel recognition sensor 23 is distributed around the center of the shell 11 to achieve 360° all-round scanning detection; the personnel recognition sensor 23 is suitable for places where cameras cannot be used, and has a wide range of applications; optionally, the personnel recognition sensor 23 is a radar with a counting function; each personnel recognition sensor 23 is in the same plane to avoid height differences that cause different personnel recognition sensors 23 to have different recognition accuracy for the human body, and is also convenient for debugging. Furthermore, there are three personnel identification sensors 23, the first personnel identification sensor 231 is installed at the center of one side of the shell 11, and the second personnel identification sensor 232 and the third personnel identification sensor 233 are respectively installed at the two ends of the side of the shell 11 away from the first personnel identification sensor 231; that is, the first personnel identification sensor 231 is installed in front of one side of the shell 11, and the second personnel identification sensor 232 and the third personnel identification sensor 233 are respectively installed at the left corner and the right corner of the other side of the shell 11; in one embodiment, the angle between the second personnel identification sensor 232 and the shell 11 is 30°, and the angle between the third personnel identification sensor 233 and the shell 11 is 150°, so as to ensure 360° all-round detection.

[0038] When in use, the number of people is identified by the personnel identification sensor 23, and the operation of the fan 12 is intelligently controlled to save energy; the air quality is monitored in real time by the air quality detection sensor 24, and the operation of the fan 12 is intelligently controlled according to the quality of the air to save energy; different lights are emitted by the color-changing light bar 25 according to the quality of the air, so that the user can understand it in time; the light sensor 26 monitors the light of the use environment, and the operation of the fan 12 is intelligently controlled to reduce noise; the microphone 27 and the noise sensor 28 cooperate to monitor the sound of gunfire or glass breaking, so that the alarm 50 can issue an alarm in time to remind the user. The received information is fed back to the cloud server 30 in real time through each controller 22 for processing, which is convenient for the subsequent overall control of users, environmental air quality, etc. In addition, since the control component 20 is installed in the air purifier host 10, the air purifier host 10 has the function of environmental monitoring, which greatly enhances the user's experience and makes the air purifier host 10 have significant application value in commercial and office environments.
[0039] The air purification system 100 of the present invention distributes a plurality of personnel identification sensors 23 around the center of the shell 11 to achieve 360° all-round scanning detection. The controller 22 controls the operation of the fan 12 according to the number of people fed back by the personnel identification sensor 23, thereby realizing intelligent control. At the same time, the controller 22 feeds back the received information to the cloud server 30 in real time for processing, so as to facilitate the subsequent overall control of users, environmental air quality, etc. The air purification system 100 is easy to use and improves the use efficiency.
