A button 9 is provided on one side of the first outer shell 1. The control component 4 includes a main board 41. The main board 41 is fixedly connected inside the second outer shell 2. A single-chip microcomputer controller 42, a WiFi communication module 43 and an AD analog-to-digital conversion module 44 are provided on one side of the main board 41. Both the WiFi communication module 43 and the AD analog-to-digital conversion module 44 are electrically connected to the single-chip microcomputer controller 42.
[0022] According to the above structure, during monitoring, external air enters the inside of the detection air duct 5. The cleaning air duct 6 is arranged inside the detection air duct 5. The monitoring sensor 7 installed on the outer wall of the cleaning air duct 6 can monitor the air entering the inside of the detection air duct 5. After the monitoring is completed, the external air of the closed detection air duct 5 enters the inside of the cleaning air duct 6 after being filtered and is sprayed out from the inside of the cleaning air duct 6 to wash and clean the monitoring sensor 7 on the outer wall of the cleaning air duct 6, avoiding dust accumulation on the surface of the monitoring sensor 7.
[0023] As Figure 3 and 4As shown, the detection airway 5 includes an L-shaped pipe 51 fixedly connected inside the first housing 1. The top end of the L-shaped pipe 51 is fixedly communicated with the top end of the first housing 1. A top cover 52 is buckled on the top end of the L-shaped pipe 51. One end of the L-shaped pipe 51 is fixedly communicated with an air hood 53. Inside the air hood 53, two symmetrically distributed fans 54 are arranged, and the air outlets of the fans 54 face the outside of the first housing 1.
[0024] According to the above structure, when monitoring, the top cover 52 is opened, and the fan 54 is started by pressing the button 9 for controlling the fan 54. The fan 54 sucks the external air into the inside of the L-shaped pipe 51. The air flows downward along the L-shaped pipe 51. When the air passes through the monitoring sensor 7, the monitoring sensor 7 can monitor the air quality. Finally, the air is discharged through the end of the air hood 53. The several monitoring sensors 7 are respectively a particulate matter sensor, a gas sensor, a temperature and humidity sensor, a negative oxygen ion sensor, and a pressure sensor.
[0025] As Figure 3 and 4 As shown, the cleaning airway 6 includes a cylinder 61. The bottom end of the cylinder 61 is fixedly communicated with a square tube 62. Several monitoring sensors 7 are fixedly installed at the bottom of the outer wall of the square tube 62. The bottom end of the square tube 62 is closed. The outer wall of the cylinder 61 is fixedly connected with connecting plates 68 evenly distributed around the axis of the cylinder 61. One end of the connecting plate 68 is fixedly connected with the inner wall of the L-shaped pipe 51. The side wall of the square tube 62 is provided with uniformly distributed through holes 63. An electromagnetic valve 64 is arranged inside the cylinder 61. The top end of the cylinder 61 is threadedly connected with a threaded tube 65. The top end of the threaded tube 65 is fixedly connected with a hemispherical frame 66. A filter screen 67 is fixedly adhered to the outer wall of the frame 66. The electromagnetic valve 64 and the fan 54 are respectively electrically connected to an external power supply through two of the buttons 9.
[0026] According to the above structure, during monitoring, the electromagnetic valve 64 is closed. After the monitoring is completed, the electromagnetic valve 64 is opened by pressing the button 9 for controlling the electromagnetic valve 64. Then, the top cover 52 is buckled on the top end of the L-shaped pipe 51. The external air enters the inside of the square tube 62 after being filtered by the filter screen 67, sprays out through the through holes 63 on the side wall of the square tube 62 and flows downward along the L-shaped pipe 51. When the air sprays out, it flushes the monitoring sensor 7, and when it flows downward, it can also flush the monitoring sensor 7, so that the dust on the surface of the monitoring sensor 7 can be cleaned. After use, the filter screen 67 is cleaned by unscrewing and removing the threaded tube 65.
[0027] As Figures 1-3 As shown, a power switch 8 is arranged on one side of the first housing 1. The main board 41 is electrically connected to an external power supply through the power switch 8. The single-chip microcomputer controller 42 is electrically connected to the display 3. Several monitoring sensors 7 are all electrically connected to the single-chip microcomputer controller 42.
[0028] According to the above structure, the monitoring sensor 7 transmits the detected signal to the single-chip microcomputer controller 42. The single-chip microcomputer controller 42 can send the signal to the terminal through the WiFi communication module 43. The AD analog-to-digital conversion module 44 converts the signal processed by the single-chip microcomputer controller 42 into a digital signal and displays it through the display 3.
[0029] The working principle of the present utility model is as follows: When monitoring, open the upper cover 52, start the blower 54 by pressing the button 9 for controlling the blower 54. The blower 54 sucks the external air into the interior of the L-shaped pipe 51. The air flows downward along the L-shaped pipe 51. When the air passes through the monitoring sensor 7, the monitoring sensor 7 can monitor the air quality. Finally, the air is discharged through the end of the air hood 53. When monitoring, the solenoid valve 64 is closed. After the monitoring is completed, open the solenoid valve 64 by pressing the button 9 for controlling the solenoid valve 64, and then fasten the upper cover 52 to the top of the L-shaped pipe 51. The external air enters the interior of the square cylinder 62 after being filtered by the filter net 67, sprays out through the through hole 63 on the side wall of the square cylinder 62 and flows downward along the L-shaped pipe 51. When the air sprays out, it flushes the monitoring sensor 7, and when it flows downward, it can also flush the monitoring sensor 7, so as to clean the dust on the surface of the monitoring sensor 7. After use, clean the filter net 67 by unscrewing and removing the threaded cylinder 65. The monitoring sensor 7 transmits the detected signal to the single-chip microcomputer controller 42. The single-chip microcomputer controller 42 can send the signal to the terminal through the WiFi communication module 43. The AD analog-to-digital conversion module 44 converts the signal processed by the single-chip microcomputer controller 42 into a digital signal and displays it through the display 3.
[0030] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
