Description

Technical Field

[0001] The utility model relates to the technical field of air particle monitors, and in particular to a high-precision air particle monitor. Background Art

[0002] An air particulate matter monitor is a device used to detect and measure the concentration of particulate matter in the air. It can help people understand the quality of the air around them, as well as the levels and distribution of air pollutants. Particulate matter is tiny particles in the air that can originate from various sources, such as vehicle emissions, industrial processes, coal burning, and cooking oil. Prolonged exposure to high levels of particulate matter can cause health problems. Therefore, it is crucial to monitor particulate matter concentrations in real time and provide relevant data and alerts.

[0003] Air particle monitors filter particulate matter from inhaled air through an internal filter, allowing particles smaller than the filter aperture to enter the monitor. These particles are then detected by an optical sensor. However, after prolonged use, the outer end of the filter at the monitor's air inlet accumulates a large amount of dust and impurities, which can easily clog the filter aperture with large particles, affecting air intake and reducing the monitor's accuracy in detecting air particle matter. To address this issue, a high-precision air particle monitor was proposed. This system uses a brush on the outer end of a side rod to clean the filter from within, addressing this issue.

The purpose of this setting is that during the monitoring process, air enters from the air inlet 205 at the bottom of the second butterfly-shaped housing 202. At this time, the filter 206 inside the air inlet 205 filters the incoming air, so that particles smaller than the aperture of the filter 206 enter the intake pipe 1. At the same time, during the air intake process, the connecting rod 207 drives the side rod 209 at the outer end to rotate inside the second butterfly-shaped housing 202, so that the bristles 2010 at its bottom end are cleaned from the inside of the filter 206. During the cleaning process, large particles of impurities adsorbed in the aperture of the outer end of the filter 206 fall off, thereby preventing the filter 206 from being blocked after long-term use, affecting the efficiency of the air intake of the intake pipe 1, and thus reducing the accuracy of the monitor body 15 in monitoring air particles.

This configuration is intended to enhance the air intake effect of the device because the radius of the first butterfly-shaped housing 201 is smaller than that of the second butterfly-shaped housing 202, and the bristles 2010 in contact with the filter 206 enhance their cleaning effect on the filter 206. The servo motor 204 is configured to drive the connecting rod 207 to rotate, thereby causing the side rod 209 to drive the bristles 2010 to swing.

At the same time, the storage rod 7 and the adapter seat 6 are connected in a rotatable manner, thereby facilitating the folding of the storage rod 7 and the air intake pipe 1, thereby facilitating the transportation and carrying of the equipment.

[0033] Preferably, a hose 9 is fixedly connected between the connecting base 5 and the receiving rod 7, and they are in communication. A limit plate is provided inside the connecting base 5, and a positioning bolt 10 is movably connected between the adapter base 6 and the receiving rod 7.
