Description

Technical Field

[0002] According to the patent document with the authorization announcement number of "CN215610388U" and the invention name of "an integrated VOCs purification device", its specification states: when using the integrated VOCs purification device, first hold the handle to lift the device and then carry the device to the desired location. The battery pack converts DC power into AC power for the entire device under the action of the inverter. Press the switch button to start the first fan and the second fan. The partition net plays an isolating and protective role for the second fan. VOCs enter the carrying box through the opening. Before entering the opening, VOCs can be filtered under the action of the filter. At this time, impurities remain on the lower end surface of the filter. After that, the activated carbon plate can adsorb harmful substances in VOCs, which is convenient for achieving the purification effect. When the battery pack is about to run out of power, it is necessary to use the charging cable to charge the battery pack in time. After the work is completed and the second bolt is loosened, the activated carbon plate can be pulled out to the right for easy replacement. However, the following defects still exist:

[0003] When VOCs pass through the activated carbon plate, it is difficult to pass through the activated carbon plate evenly, so a part of the activated carbon plate often performs absorption work, while the other part of the activated carbon plate performs less absorption work. After the activated carbon plate that often performs absorption work becomes ineffective after long-term use, the absorption efficiency of the activated carbon plate is reduced, resulting in low utilization rate of the activated carbon plate and short service life.
