Specifically, as shown in Fig. 4 and Fig. 20-Fig. 22, the bed brush 22 also includes a rolling brush cover 223, and the rolling brush cover 223 is installed on the outer surface of the bed brush lower cover 222, and the bed brush lower cover 222 lies on the rolling brush cover. The corresponding position of 223 is concaved inwardly to form an accommodating space for accommodating the roller brush 224 , and a through hole is arranged on the roller brush cover 223 , and the through hole forms a dust suction port 2221 . Wherein, a first chamber is formed between the bed brush upper cover 221 and the bed brush lower cover 222 , and a second chamber is formed between the bed brush lower cover 222 and the rolling brush cover 223 .

As shown in FIGS. 20 and 21 , a connecting pipe 226 is arranged in the bed brush 22 , and the connecting pipe 226 is fixed on the bed brush lower cover 222 , and one end extends out of the bed brush 22 and is connected with the hose 21 . The connecting pipe 226 is a tubular structure, and one end extending out of the bed brush 22 is provided with a connecting port 227, the connecting port 227 is connected with the flexible pipe 21, and the other end is closed. The connecting pipe 226 is provided with a first opening and a second opening at the side and the closed end respectively, wherein the first opening communicates with the first chamber, and the second opening communicates with the second chamber.

As shown in Figure 21 and Figure 22, in order to realize that the hose 21 selectively communicates with the dust suction port 2221 or the hot air outlet 2211, the first opening is movably connected with a first flap 2261 for blocking the first opening, and the second opening A second blocking piece 2262 for blocking the second opening is movably connected thereto. When the first flap 2261 is opened, the second flap 2262 blocks the second opening, so that the hose 21 communicates with the first chamber, that is, the hose 21 communicates with the hot air outlet 2211; when the second flap 2262 is opened, the second A blocking piece 2261 blocks the first opening, so that the hose 21 communicates with the second chamber, that is, the hose 21 communicates with the suction port 2221 .

In order to enable the first flap 2261 and the second flap 2262 to open or close correspondingly with the switching of the dust removal mechanism 3 and the hot air mechanism 4, the first flap 2261 can be rotatably arranged on the outer wall of the connecting pipe 226, and the first flap The size of the side is greater than the size of the first opening, so that the edge of the first rib can abut against the outer wall of the connecting pipe 226; The size is larger than the size of the second opening, and the edge of the second rib abuts against the inner wall of the connecting pipe 226 .
