The air inlet channel 114 and the air outlet channel 115 of the accommodating assembly 11 are abutted against the inner wall of the first cover member 81. The shroud assembly 80 provides further securement for the containment assembly 11, avoiding rattling of the containment assembly 11 during use, and further improving stability of the fan 12 in the containment assembly 11.

Further, to avoid the effect of the shroud assembly 80 on the heat dissipation of the blower 12 and the extraction of the air in the sewage tank 40, the first shroud member 81 is provided with openings at the positions of the heat dissipation inlet of the air intake channel 114 and the heat dissipation outlet of the air outlet channel 115, and the second shroud member 82 is also provided with openings at the positions corresponding to the air suction cavity 1173a of the third support housing 1173. Through the opening, cold air can enter the air inlet channel 114, and hot air can be discharged from the air outlet channel 115. The gas in the sewage tank 40 can enter the suction chamber 1173a, thereby enabling the formation of negative pressure in the sewage tank 40.

Preferably, the openings on the first cover member 81 and the second cover member 82 are both mesh, so as to filter particulate matters, dust, bacteria, etc., and prevent the sucked air from affecting the normal use of the fan 12. While the mesh openings can increase the strength and durability of the first and second shields 81, 82.

The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.

The above examples only represent a few embodiments of the present application, which are described in more detail and are not to be construed as limiting the scope of the claims. It should be noted that it would be apparent to those skilled in the art that various modifications and improvements could be made without departing from the spirit of the present application, which would be within the scope of the present application. Accordingly, the scope of protection of the present application is to be determined by the claims appended hereto.
