When the hose connector 51 slides, the hose connector 51 can be connected to the third pipeline 43 or the second pipeline 34 only by ensuring that the nozzle of the hose connector 51 is aligned with the first communication hole or the second communication hole.

As shown in fig. 19, in order to facilitate the user to manually switch the dust removing mechanism 3 and the hot air mechanism 4, the function switching assembly 5 further includes a switching operation member 511, the rear housing 12 is further provided with a strip-shaped hole 122 at a corresponding position of the hose connector 51, the strip-shaped hole 122 is arranged along the sliding direction of the hose connector 51, and the switching operation member 511 passes through the strip-shaped hole 122 and is connected with the hose connector 51. When a user needs to switch the function, the user only needs to slide the switching operation piece 511 to the other end of the strip-shaped hole 122, so that the operation is convenient and quick.

In order to prevent the switching operation member 511 from sliding after the switching operation member 511 slides, so as to ensure that the hose connector 51 is aligned with the first communication hole or the second communication hole, a limiting protrusion may be further disposed at the middle portion of the strip-shaped hole 122, after the hose connector 51 slides in place, the switching operation member 511 is clamped and fixed between the limiting protrusion and the side wall corresponding to the strip-shaped hole 122, and the switching operation member 511 is prevented from moving by the cooperation of the limiting protrusion and the side wall corresponding to the strip-shaped hole 122, so as to ensure that the hose connector 51 is aligned with the first communication hole or the second communication hole. In this embodiment, two limiting protrusions may be provided, and the size of each limiting protrusion should not be too large, so as to prevent the switching operation component 511 from being unable to overcome the resistance of the limiting protrusion to move in place.

In order to further improve the intellectualization of the bed quilt dryer, the function switching component 5 can also automatically complete the switching between the dust removing mechanism 3 and the hot air mechanism 4. The function switching component 5 may further include a motor and a transmission component, the transmission component is connected to the hose connector 51, and the motor drives the transmission component to operate, so as to drive the hose connector 51 to move. In this embodiment, the transmission assembly may be a rack and pinion assembly, the hose connector 51 is provided with a rack 512, and a gear (not shown) driven by a motor (not shown) is engaged with the rack 512 for transmission. When the motor drives the gear to rotate forwards and backwards, the gear and the rack 512 can be matched to drive the hose connector 51 to move back and forth, so that the dust removing mechanism 3 and the hot air mechanism 4 can be switched.

In order to prevent the hot air outlet 2211 from being communicated with the dust removing channel to influence the dust removing effect, or the dust collection port 2221 is communicated with the hot air channel to influence the work of the hot air mechanism 4, the dust collection port 2221 on the bed brush 22 is not communicated with the hot air outlet 2211, and the hose 21 is selectively communicated with the dust collection port 2221 or the hot air outlet 2211. A first chamber and a second chamber are arranged in the bed brush 22, and the first chamber is not communicated with the second chamber, wherein the dust suction port 2221 is arranged on the side wall of the second chamber, and the hot air outlet 2211 is arranged on the side wall of the first chamber.

Specifically, as shown in fig. 4, 20-22, the bed brush 22 further includes a rolling brush cover 223, the rolling brush cover 223 is mounted on an outer surface of the bed brush lower cover 222, the bed brush lower cover 222 is recessed inward at a position corresponding to the rolling brush cover 223 to form an accommodating space for accommodating the rolling brush 224, and a through hole is formed in the rolling brush cover 223 and 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 fig. 20 and 21, a connection pipe 226 is provided in the bed brush 22, the connection pipe 226 is fixed on the bed brush lower cover 222, and one end of the connection pipe 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 of the connecting pipe, which extends out of the bed brush 22, is provided with a connecting port 227, the connecting port 227 is connected with the hose 21, and the other end is closed. The connection pipe 226 is provided at a side portion and a closed end with a first opening and a second opening, respectively, wherein the first opening is communicated with the first chamber and the second opening is communicated with the second chamber.

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

In order to enable the first blocking piece 2261 and the second blocking piece 2262 to be opened or closed correspondingly with the switching of the dust removing mechanism 3 and the hot air mechanism 4, the first blocking piece 2261 may be rotatably disposed on the outer wall of the connecting pipe 226, and the size of the first blocking edge is larger than that of the first opening, so that the edge of the first blocking edge can abut against the outer wall of the connecting pipe 226; the second retaining piece 2262 can be rotatably disposed on the inner wall of the connecting pipe 226, and the size of the second retaining edge is larger than that of the second opening, and the edge of the second retaining edge abuts against the inner wall of the connecting pipe 226.

When the second duct 34 in the dust removing mechanism 3 is communicated with the hose 21, a certain vacuum environment is formed in the dust removing passage, the air pressure outside the bed-to-bed dryer is higher, and the air pressure inside the bed-to-bed dryer is lower, at this time, the first blocking piece 2261 is pressed and abutted on the outer wall of the connecting pipe 226 under the action of the pressure difference because of being located at the outer side of the connecting pipe 226, that is, the first blocking piece 2261 automatically blocks the first opening, the hot air outlet 2211 is not communicated with the connecting pipe 226, that is, the hot air outlet 2211 is not communicated with the hose 21. In contrast, since the second stopper 2262 is located in the connection pipe 226, the second stopper 2262 is opened by the airflow under the pressure difference, so that the dust suction port 2221 is communicated with the connection pipe 226, i.e., the dust suction port 2221 is communicated with the hose 21, thereby accomplishing the dust removal purpose.

Contrary to the above process, when the third duct 43 of the hot air mechanism 4 is communicated with the hose 21, the fan 41 and the heating assembly 42 are operated, so that hot air is generated in the hot air passage, and the hot air enters the connecting pipe 226 through the hose 21. Because the second stopper 2262 is located in the connecting tube 226, under the action of hot wind, the second stopper 2262 is pressed and abutted against the inner wall of the connecting tube 226, that is, the second stopper 2262 automatically blocks the second opening, and the dust collection port 2221 is not communicated with the connecting tube 226, that is, the dust collection port 2221 is not communicated with the hose 21. On the contrary, since the first stopper 2261 is located at the outer side of the connection pipe 226, the first stopper 2261 rotates relative to the connection pipe 226 to open the first opening under the pushing of the hot wind, so that the hot wind outlet 2211 is communicated with the connection pipe 226, that is, the hot wind outlet 2211 is communicated with the hose 21, thereby achieving the purpose of drying or removing mites.

The above description is only a preferred embodiment of the present invention, and for those skilled in the art, the present invention should not be limited by the description of the present invention, which should be interpreted as a limitation.
