[0059] Specifically, the guide protrusion 140 is accommodated in the first guide groove 240 and can abut against the side wall of the first guide groove 240 , so as to guide the air inlet cover 200 to enter the accommodating cavity 110 along the air inlet port 120 , thereby facilitating the assembly of the air inlet cover 200 .

[0060] It should be noted that the positions of the guide protrusion 140 and the first guide groove 240 can also be interchanged, that is, the guide protrusion 140 is arranged on the air inlet cover 200, and the first guide groove 240 is arranged on the side wall of the accommodating cavity 110, which is not limited here.

[0061] It should be pointed out that the first guide structure may also be a structure in which a guide shaft cooperates with a guide hole, which will not be described in detail here.

[0062] In some embodiments of the present invention, three guide protrusions 140 are configured, and the three guide protrusions 140 are arranged at intervals along the circumference of the shell 100. The spacings between adjacent guide protrusions 140 are different, which can play an anti-mistake effect, so that the first buckle 210 can be aligned with the corresponding second buckle 150, and the relative position deviation between the air inlet cover 200 and the shell 100 can be avoided due to misoperation by the assembler.

[0063] Specifically, there are three corresponding first guiding grooves 240, and the distances between adjacent first guiding grooves 240 are different. Only when one of the three guiding protrusions 140 is aligned with the corresponding first guiding groove 240, the other two guiding protrusions 140 can be aligned with the remaining first guiding grooves 240, which can play an anti-mistake role, enabling the first buckle 210 to be aligned with the corresponding second buckle 150 and avoiding the situation where the relative positions of the air inlet cover 200 and the housing 100 deviate due to misoperation by the assembly personnel.

[0064] Referring to Figure 7 、 Figure 8 , in some embodiments of the present invention, a second guiding structure is provided between the air outlet cover 300 and the housing 100, which can guide the air outlet cover 300 to move along a preset direction, facilitating the assembly of the air outlet cover 300.
