[0017] A method for automatically calibrating an ambient air quality monitoring device comprises the following steps;

[0018] Step one: When air enters, the filter mechanism can first filter the impurities in the air through the filter screen in the filter box to prevent the impurities from entering the monitor with the air, thereby affecting the detection data of the monitor. When the filter screen filters impurities for a long time, accumulation problems will occur. Too many impurities will affect the filtering effect of the filter screen, making it inconvenient for the air to circulate in the protective shell. At this time, the transmission mechanism is rotated to rotate the half-gear disk. During the rotation, the half-gear disk will drive the rack to move in a straight line, and the rack will drive the sliding seat to move to the left. During the movement, the sliding seat will also drive the cleaning brush to move. During the movement, the cleaning brush will also clean the impurities attached to the surface of the filter screen, so that the filtering efficiency of the filter screen is better. The guide rod can play a guiding and stabilizing role in the movement of the sliding seat.

[0019] Step 2: By locating the collection box directly below the filter, the impurities on the surface of the filter can be collected during the cleaning process to avoid the impurities falling directly into the filter box and requiring cleaning again. In addition, by opening the installation slot, the collection box can be disassembled regularly to regularly clean the impurities collected in the collection box.

[0020] Step three: By setting the reset spring, the reset spring can be compressed during the movement of the sliding seat, so that when the half gear plate and the rack are misaligned, the sliding seat can be automatically reset on the surface of the guide rod under the action of the rebound force of the reset spring, so that the rack and the half gear plate can be meshed again, so that reciprocating linear cleaning can be performed.

[0021] Compared with the prior art, the present invention provides an ambient air quality monitoring device and method for automatic calibration, which has the following beneficial effects:

[0022] 1. The environmental air quality monitoring device for automatic calibration rotates the half gear disk by the rotation of the transmission mechanism, and the half gear disk drives the cleaning brush between the sliding seats to move, so that the impurities on the filter net can be cleaned in time. By setting it in this way, it can clean the impurities attached to the filter net, and can clean it multiple times by reciprocating linear motion, so as to avoid excessive impurities that easily affect the speed of air circulation, thereby ensuring the quality of later detection.

[0023] 2. The environmental air quality monitoring device for automatic calibration can rotate the filter screen under wind force through the cooperation between the rotating rod, the connecting rod and the blades. In the absence of wind, the fan blades can be rotated again through the cooperation between the motor, the bevel gear 1 and the bevel gear 2. This arrangement allows a dual-drive mode and a single air intake to avoid accidental failure to drive in a single mode, thereby ensuring the efficiency of air intake.

[0024] 3. The environmental air quality monitoring device for automatic calibration can disperse the desiccant through the cooperation of the drying cylinder, connecting rod two, connecting rod three and rotating blades, and under the linkage drive of connecting rod one. By setting it in this way, the desiccant can be fully mixed with the moisture in the air, so as to ensure that each desiccant can fully absorb moisture, so that the moisture in the air is greatly reduced, thereby improving the accuracy of air monitoring data.

[0025] The parts not involved in the device are the same as the existing technology or can be implemented by the existing technology. The present invention can clean up the impurities in the air in time to avoid excessive impurities affecting the speed of air circulation, and can ensure better efficiency in absorbing air. At the same time, it can dry and adsorb the moisture in the air, so that the humidity in the air is greatly reduced, thereby improving the accuracy of air monitoring data.

10. A method for automatically calibrating an ambient air quality monitoring device according to any one of claims 1 to 9, characterized in that: The steps include: Step 1: When air enters, the filter mechanism (6) can first pass through the filter screen (64) in the filter box (61) to filter impurities in the air, thereby preventing impurities from entering the monitor (2) along with the air, thereby affecting the detection data of the monitor (2). When the filter screen (64) filters impurities for a long time, accumulation problems will occur. Excessive impurities will affect the filtering effect of the filter screen (64), thereby making it difficult to circulate the air in the protective housing (1). At this time, the transmission mechanism (5) is rotated to make it The half gear plate (8) is rotated. During the rotation process, the half gear plate (8) drives the rack (612) to move linearly. The rack (612) drives the sliding seat (63) to move leftward. During the movement process, the sliding seat (63) drives the cleaning brush (65) to move. During the movement process, the cleaning brush (65) cleans the impurities attached to the surface of the filter screen (64), thereby improving the filtering efficiency of the filter screen (64). The guide rod (62) can play a guiding and stabilizing role in the movement process of the sliding seat (63). Step 2: The collecting box (68) is located directly below the filter (64), so that the impurities on the surface of the filter (64) can be collected during the cleaning process, thereby preventing the impurities from falling directly into the filter box (61) and requiring cleaning again. In addition, by opening the mounting groove (67), the collecting box (68) can be disassembled regularly, so that the impurities collected in the collecting box (68) can be cleaned regularly. Step three: By setting the reset spring (66), the reset spring (66) can be compressed during the movement of the sliding seat (63). Therefore, when the half gear plate (8) and the rack (612) are misaligned, the sliding seat (63) can be automatically reset on the surface of the guide rod (62) under the action of the rebound force of the reset spring (66), so that the rack (612) and the half gear plate (8) can be meshed again, so as to facilitate reciprocating linear cleaning.
