Description

A flip air purifier

technical field

The utility model belongs to the technical field of purifiers, and relates to an overturned air purifier.

Background technique

In order to ensure the good operation of the air purifier, the air purifier needs to replace the filter regularly. Some existing air purifiers are inconvenient to disassemble and assemble, and some must remove the entire panel before replacing the filter. It is time-consuming and labor-intensive, very inconvenient, and it is also easy to dismantle the panel.

For example, a utility model patent with an application number of CN201721185123.2 provides a novel high-efficiency air purifier, comprising: a base, a box mounted on the base, a cover plate and an air intake guide plate, the cover plates are respectively Installed on the front and rear sides of the box body, the air intake guide plates are respectively installed on the left and right sides of the box body; the cover plate is hinged on the base, and the front and rear sides of the box body are respectively provided with useful In the filter cavity where the filter screen is placed, an air intake channel is arranged around the box body, and the air enters the filter cavity through the air intake guide plate and the air intake channel in sequence.

To sum up, although some existing technical solutions only need to turn and open the cover when replacing the filter, the filter on the box can be directly pulled out, which solves the problem of troublesome replacement of the filter, but because the cover is only simple It is hinged with the base, so if it is opened with too much force, the cover will be dismantled, which has a large room for improvement.
