[0033] A specific embodiment of the utility model is as follows Figure 1-5 As shown, a PM2.5 monitoring device with moisture-proof function is disclosed, including:

[0034] The mounting plate 1 has a bottom plate 102; the bottom plate 102 has an air inlet 102a and an air outlet 102b;

[0036] A monitoring component 3 is provided at the air inlet 102a on the bottom plate 102, and the monitoring component 3 includes a concentration detection device 301 for detecting the concentration of particulate matter PM2.5 in the air entering the concentration detection device 301 from the air inlet 102a;

[0037] The moisture discharge component 4 includes a discharge pipe 401 and an exhaust fan 402. The discharge pipe 401 is arranged on both sides of the concentration detection device 301. The exhaust fan 402 is arranged at the exhaust port 102b on the bottom plate 102 and is connected to the discharge pipe 401 to discharge the heated moisture from the monitoring component.

[0038] During implementation, first, install the monitoring component 3 at the air inlet 102a of the base plate 102; secondly, install the discharge pipe 401 of the moisture discharge component 4 on both sides of the concentration detection device 301, install the exhaust fan 402 at the exhaust port 102b of the base plate 102, and connect it to the discharge pipe 401; then, insert and fix the installed mounting plate 1 from the bottom opening of the outer shell 2 to complete the installation work; when in use, the air in the environment enters the monitoring component 3 through the air inlet 102a, and the concentration of particulate matter PM2.5 in the air is detected by the concentration detection device 301, and the moisture in the monitoring device is heated by the heating plate 201 on the inner wall of the outer shell, and then the heated moisture is discharged from the monitoring device through the exhaust port 102b through the discharge pipe 401 and the exhaust fan 402.

[0039] Compared with the prior art, the particulate matter PM2.5 monitoring device with moisture-proof function provided in this embodiment heats the moisture in the monitoring device through a heating plate, and discharges the heated moisture out of the monitoring device through a moisture discharge component to ensure that the inside of the device is dry, thereby reducing the impact of air moisture on internal components, thereby improving the accuracy of detection data.

[0040] In this embodiment, the mounting plate 1 further comprises a vertical plate 101, and the vertical plate 101 is perpendicular to the bottom plate 102; the monitoring component 3 further comprises a dehumidification device 302 for removing moisture from the air entering the concentration detection device 301 through the air inlet 102a.

[0041] Exemplarily, the dehumidification device 302 includes an electric heating device such as a resistance wire and a heating plate to remove moisture from the air entering the monitoring component 3, thereby preventing the moisture from corroding the device in the monitoring component 3.

[0043] Specifically, the air entering through the air inlet 102a may have some residue after the moisture is removed by the dehumidification device 302.

After the air in the environment enters the concentration detection device 301, the laser transmitter emits a laser that passes through the air and is captured by the photosensitive receiver, which converts the light signal into an electrical signal representing the concentration of particulate matter PM2.5; after the data processing module 301 receives the electrical signals generated by the concentration detection device 301 and the humidity sensor, they are converted into corresponding digital signals and stored as concentration information and humidity information for the next step of transmission or processing.

[0046] In this embodiment, the communication component 6 further includes a data transmission module 602 for transmitting the humidity information to the control component 5 and transmitting the concentration signal to a background or a mobile terminal.

[0047] Specifically, the data transmission module 602 can use various communication protocols and technologies, such as Bluetooth, Wi-Fi or mobile networks, to transmit the humidity information to other components, and transmit the concentration signal to other devices or cloud servers to achieve real-time or delayed transmission to meet the needs of different application scenarios.

[0048] In this embodiment, the control component 5 further includes a control module for controlling the opening or closing of the heating plate 201 and the exhaust fan 402 according to the humidity information.

[0049] Specifically, the control module receives the humidity information, determines the humidity of the air in the current monitoring device according to the humidity information, and a first humidity threshold and a second humidity threshold are pre-set in the control module; if the current air humidity is greater than the second humidity threshold, the control module issues a control instruction to turn on the heating plate 201 and the exhaust fan 402; after a period of heating, if the air humidity is less than the first humidity threshold, the control module issues a control instruction to turn off the heating plate 201 and the exhaust fan 402.

[0050] In this embodiment, a switch button 102c is also provided on the bottom plate 102 for turning on or off the monitoring device.

[0051] Specifically, the switch button 102c is configured for the user to manually turn on or off the monitoring device, which helps to improve the controllability of the monitoring device and quickly stop or restart the monitoring process when necessary, thereby more flexibly responding to different monitoring needs and environmental changes.

[0053] Specifically, the size of the outer shell 2 is 15mm-25mm longer than that of the heating plate 201, which can effectively prevent rainwater and the like from penetrating into the monitoring device; the base plate 102 is detachably connected to the bottom edge of the heating plate 201 by positioning bolts, which facilitates maintenance of the various components installed on the mounting plate 1.

[0054] In this embodiment, a power supply component 7 is further included, which is arranged on the vertical plate 101 and is used to provide power to the monitoring component 3, the exhaust fan 402, the control component 5 and the communication component 6.

[0055] Specifically, the power supply component 7 is used to convert the external 220V voltage into the 12V working voltage of the monitoring device.

[0056] In this embodiment, a GPS positioning antenna 202 is provided on the top of the housing 2, and a corresponding interface 203 is provided on the bottom plate 102 for detecting the position of the monitoring device.

[0057] Exemplarily, the GPS positioning antenna 202 is fixed to the top surface of the housing 2 by a built-in magnetic suction cup, which is easy to assemble and disassemble and firmly fixed. The interface 203 is electrically connected to the power supply component 7 to provide power for the GPS positioning antenna 202.
