It will be appreciated that if the filter screen 20 is installed by the first connector 40 and the first socket 60, in this case, the first connector 40 and the first socket 60 need to be distributed on four inner walls of the ventilation opening 11 to perform a good fixing function, and the filter screen 20 can be disassembled only along the vertical direction, that is, the first connector 40 needs to be pulled up one by one to complete the disassembly of the filter screen 20, which is slightly troublesome.

In order to solve the above-mentioned problem, in this embodiment, the second connector 50 may be detached from the non-vertical direction, and the first socket 60 and the second socket 70 are also located on different inner walls of the vent 11, it may be understood that the first socket 60 may perform a good fixing function without being distributed on four inner walls of the vent 11, for example, the first socket 60 may be distributed on only one, two or three inner walls of the vent 11, the second socket 70 may be distributed on only one inner wall of the vent 11, so as to achieve a good fixing function, and when the first connector 40 is detached, the second connector 50 may be pulled up only, so that the filter screen 20 may be detached by pulling out the second connector 50 in the non-vertical direction.

Regarding the distribution and the number of the first sockets 60 and the second sockets 70, the distribution and the number of the first sockets 60 and the second sockets 70 are not limited specifically, and the distribution and the number of the first sockets 60 and the number of the second sockets 70 can be changed according to practical situations, for example, only one first socket 60 and one second socket 70 can be arranged and are positioned on different inner walls of the ventilation opening 11, when the filter screen 20 can be detached, the first connecting piece 40 can be pulled upwards, and then the second connecting piece 50 can be pulled out along the non-vertical direction, so that the filter screen 20 can be detached more conveniently and quickly, and it can be understood that two first sockets 60 and one second socket 70 can be arranged, and the effect of convenient detachment can be realized on the basis of ensuring good fixing effect.
