The dust filter part 9 of rubbish, in the present embodiment, the dust filter part 9 is a square dust filter bag similar to the shape of the storage cavity 6 inner cavity; a transmission channel is formed in the transition cavity 5, and one end of the transmission channel is connected to the outlet end of the air channel 3, And the other end of the transmission channel penetrates into the storage chamber 6 and communicates with the inlet of the dust filter 9. On the dust collection box 2, the transition chamber 5, the storage chamber 6 and the power chamber 7 move away from the wind in the dust collection box 2 horizontal direction. The direction of the inlet end of channel 3 is arranged in sequence.

After the fan 8 starts to work, the garbage enters the dust filter 9 from the storage box through the air duct 3 and the pipe 11, thereby realizing the emptying work of the sweeping robot. The emptying work refers to the garbage collected by the sweeping robot storage box Clean up, and in this process, can shorten the path between rubbish and dust filter 9, rubbish is shorter in the way from bottom to top in vertical direction afterwards in addition, by contrast, blower fan 8 produces less wind power and just can To realize the emptying of the sweeping robot, the working power required by the fan 8 to drive the gas flow between the entire dust collection box 2 and the air duct 3 is small, so that power consumption can be reduced.

Referring to Figures 1 and 2, in order to further reduce the path of garbage during the emptying process, a first relief groove 10 for one end of the base 1 to be embedded is provided on the side of the dust collection box 2 close to the base 1, and the second A relief groove 10 is opened below the transition chamber 5, and the outlet end of the air duct 3 is set on the end of the base 1 embedded in the first relief groove 10 and on the side close to the transition chamber 5, and the end of the base 1 is embedded in the first relief groove. After the location slot 10, the inlet end of the transmission channel is vertically connected and connected to the outlet end of the air channel 3, thereby reducing the horizontal path from the garbage to the dust filter 9.

Referring to Fig. 2, in the present embodiment, the transmission channel includes a pipeline 11 installed in the storage cavity 6, and the inlet end of the pipeline 11 passes through the storage cavity 6 and is connected to the outlet end of the ventilation channel 3 on the side wall near the first relief groove 10, The outlet end of the pipe 11 penetrates into the storage chamber 6 and connects with the inlet of the dust filter 9 .

Referring to Fig. 4 and Fig. 5, after the dust filter 9 is installed in the storage chamber 6, it is necessary to ensure that the inlet end of the dust filter 9 and the outlet end of the pipeline 11 maintain a continuous butt connection, so the position of the dust filter 9 needs to be limited For this reason, a positioning block 12 is integrally formed on the side of the dust filter 9 close to the pipe 11, and the positioning block 12 extends to the bottom wall of the dust filter 9 and is flush, and is located on the inner wall of the storage chamber 6 away from the power chamber 7 and located on the pipe 11 Both sides of the outlet end are integrally formed with two side-by-side strips 13, and a positioning strip 14 is formed on the opposite side of the two strips 13, and a spacer is formed between the two positioning strips 14, the two strips 13 and the inner wall of the storage chamber 6. The positioning space where the positioning block 12 is embedded, when the dust filter 9 is assembled, the positioning block 12 on the dust filter 9 is embedded in the positioning space, and the end surface of the positioning block 12 near the bottom of the storage cavity 6 is abutted against the storage cavity 6 On the bottom wall, at this time, the inlet end on the dust filter 9 can be connected with the outlet end of the pipeline 11 and communicated, and it can also ensure that the inlet end on the dust filter 9 and the outlet end of the pipeline 11 remain stable.

Referring to Figures 5 and 6, during the use of the emptying station, a certain amount of garbage is stored in the dust filter 9. If too much garbage is accumulated in the dust filter 9, it will affect the fan 8 to drive the storage chamber 6, the pipe 11 and the air duct. The efficiency of the gas flow between 3 affects the emptying work of the sweeping robot, so it is necessary to regularly clean up the garbage in the dust filter 9, so an installation port 15 is opened on the side wall of the top side of the storage chamber 6, and in A sealing plate 16 is detachably installed on the installation opening 15, and the storage chamber 6 can be in a sealed state after the sealing plate 16 is installed.

In order to realize the detachability of the sealing plate 16 on the dust collecting box 2, a connecting block 17 is formed on the side wall of the sealing plate 16 facing the power chamber 7, and the connecting block 17 is integrally formed with a fixed part facing the power chamber 7.
