technical field

The present application relates to the technical field of air purification, in particular to an air purifier.

Background technique

Air purifiers refer to products that can absorb, decompose or transform various air pollutants and effectively improve air cleanliness.

Generally, an air cleaner includes a casing, a filtering device and a fan, and the filtering device and the fan are installed inside the casing. The housing is provided with an air inlet and an air exhaust port, and the fan sucks the air from the outside of the housing into the inside of the housing and discharges the filtered air. The external air enters the inside of the casing from the air inlet under the action of the fan, and then the air is filtered by the filter device and then discharged from the air outlet, so as to achieve the effect of purifying the air.

For the related technologies mentioned above, the general filter device has a certain timeliness. After using the air purifier for a long time, the filtering effect of the filter device will be reduced, so the filter device will be cleaned or replaced regularly. The inventor believes that: the filter device is installed inside the casing, and the casing needs to be disassembled for replacement, and then replaced, which makes it inconvenient to replace the filter device.
