The method for removing the filter screen of the air cleaning apparatus of the present invention will be described with reference to a specific example. Fig. 11 is an exploded schematic view of an air purifying device, a filter module is installed at an air return opening of an indoor unit of a patio, the air return opening is provided with a panel 7, a grid 1 is arranged in a square hole in the center of the panel 7, the filter module is installed between the grid 1 and the panel 7, specifically, a coarse filter screen is installed on the grid 1 through a second buckle structure 6, a HEPA filter screen is installed on the coarse filter screen through a first buckle structure 4, and the specific structures of the first buckle structure 4 and the second buckle structure 6 are shown as a side view in fig. 4. The plurality of gaps in the grille 1 allow air to enter the raise-boring machine and the grille 1 can be removed directly from the face plate 7.
There are two alternatives when the user needs to replace the filter screen. Firstly, the grille 1 is detached from the panel 7, and if the HEPA filter screen needs to be replaced, the HEPA filter screen is only taken out and replaced; if the coarse filter screen needs to be replaced, the HEPA filter screen can be detached firstly, then the coarse filter screen is detached, or the filter module can be detached integrally, and then the coarse filter screen and the HEPA filter screen are separated. Secondly, the grid 1 is rotated outwards by a certain angle relative to the panel 7 without being detached, and the filter screen can be detached from the exposed operation space.
Therefore, the whole process does not need to use other tools, and the operation is convenient. Because the mounting position of the courtyard machine is higher, the grid 1 is also difficult to detach from the panel 7, and the adoption of the buckle connection structure can enable the filter screen to be replaced when the filter screen is required, even if the grid 1 is not detached, the filter screen can be directly detached from the courtyard machine and conveniently replaced by a new filter screen, when an operator stands on a higher ladder or other positions to operate, auxiliary work is not required to be carried, the problem that matching parts such as fasteners fall off is avoided, and after replacement is completed, the filter screen is replaced more quickly only by rotating the grid 1 to the initial position. Moreover, the mode of directly rotating the grid 1 by a certain angle to replace the filter screen can also avoid the possibility that the detached grid 1, namely the filter module, falls down due to operator error, and the safety of the filter screen during replacement is improved.
According to another aspect of the present invention, there is also provided a patio machine including the patio machine air cleaning device described in each of the above embodiments. All parts in the air purification device are connected by adopting a buckle structure, so that the efficiency of the raise-boring machine in assembly is higher, and the filter screen can be conveniently and rapidly replaced in the use process.
