Description

Technical Field

[0001] The utility model relates to the technical field of monitors, in particular to a portable air quality monitor. Background Art

[0002] An air monitor is an instrument for atmospheric testing. It can simultaneously monitor gas and inhalable particulate matter concentrations, displaying them on the same screen. One instrument can monitor four parameters simultaneously. The instrument operates with automatic sampling and analysis, displaying the measured concentration directly on the screen and automatically calculating daily and monthly averages. It can store 30 days of monitoring data (including daily and monthly averages). The instrument is equipped with USB and RS485 data transfer interfaces, allowing the stored data to be transferred to a computer.

[0003] In order to monitor the air quality in real time in various places, most air monitors need to be installed in outdoor environments. Considering that the installation conditions of air monitors in outdoor environments are not ideal, there may be obstructions at the installation site, resulting in inaccurate monitoring data. Considering the complexity of the outdoor environment, which hinders its carrying, disassembly and replacement, it is necessary to make it easy to disassemble and carry. In addition, the air monitors installed outdoors must ensure their stability to ensure their long-term operation environment and avoid damage caused by rain, exposure to the sun, etc. To this end, we propose a portable air quality monitor to solve the above problems.

When it rains, rainwater falling on the top of the mounting platform 1 will flow downward along the inclined annular surface 101 around the mounting platform 1, and the rainwater will flow into the guide groove 102 at the bottom of the inclined annular surface 101. The rainwater in the guide groove 102 is discharged through multiple leakage holes 103 evenly distributed and running through the mounting platform 1, thereby preventing rainwater from accumulating on the top of the mounting platform 1 and causing damage to the monitor body 2.

The bottom of the shielding shell 301 is fixedly connected to the assembly table 104, and the assembly table 104 is sleeved around and fixedly connected to the mounting table 1. The closed shell 302 is slidably connected to the shielding shell 301, and the bottom of the closed shell 302 is in contact with the surface of the assembly table 104.
