[0050] Reference Figure 1-Figure 10 , this embodiment provides a dust box structure 100, which is used to connect to the dust collection base station 300 outside, including a host dust suction device 1, a host dust collection device 2, a host air duct module 3 and a host dust outlet channel 4;

[0051] The host dust collecting device 2 is respectively connected to the host air duct module 3 and the host dust outlet channel 4, and the host air duct module 3 is arranged opposite to the host dust outlet channel 4, wherein the host dust outlet channel 4 is located above the drum of the sweeping machine 200, and the channel dust outlet of the host dust outlet channel 4 away from the end of the host dust collecting device 2 is located on the side of the rear of the sweeping machine 200;

[0052] The host air duct module 3 includes a host air outlet channel 30 and a host air inlet channel 31 arranged corresponding to the host air outlet channel 30. The host dust suction device 1 is connected between the host air outlet channel 30 and the host dust collecting device 2. The host dust suction device 1 is used to provide a host dust suction airflow.

[0053] During the dust removal process, the base station outgoing airflow of the dust collection base station 300 flows into the host dust collection device 2 from the host air outlet channel 30 and the host air inlet channel 31 respectively to form a circulating turbulent flow, or the host dust suction airflow passes through the reflection wall 306 of the dust collection base station 300 and flows into the host dust collection device 2 from the host air inlet channel 31 to form a circulating turbulent flow, and cooperates with the base station dust suction airflow of the dust collection base station 300 to collect dust through the host dust outlet channel 4.

[0054] In the above embodiment, the dust box structure 100 is used to work in conjunction with the dust collection base station 300 to realize the dust collection function of the sweeping machine 200. The dust box structure 100 includes a host dust suction device 1, a host dust collection device 2, a host air duct module 3 and a host dust outlet channel 4. The host dust suction device 1 is responsible for generating dust suction airflow and is the power source for the entire dust collection process. The host dust collection device 2 is used to temporarily store dust and other debris collected during the cleaning process. It is connected to the host air duct module 3 and the host dust outlet channel 4, and the host air The duct module 3 is arranged opposite to the main machine dust outlet channel 4, and the main machine air duct module 3 includes a main machine air outlet channel 30 and a main machine air inlet channel 31, and the main machine air outlet channel 30 and the main machine air inlet channel 31 are arranged correspondingly, wherein the main machine dust outlet channel 4 is located above the drum of the sweeping machine 200, and the dust outlet of the main machine dust outlet channel 4 away from the end of the main machine dust collecting device 2 is located on the side of the rear of the sweeping machine 200, so as to realize the side dust collection when the drum type sweeping machine 200 cooperates with the dust collecting base station 300, and the main machine dust outlet channel 4 The dust in the host dust collecting device 2 is guided to the dust collecting base station 300. The host dust suction device 1 is connected between the host air outlet channel 30 and the host dust collecting device 2. The host air inlet channel 31 is mainly used to guide the external airflow into the host dust collecting device 2. When the host dust collecting device 2 blows air to the host air outlet channel 30, negative pressure is formed in the host dust suction device 1, thereby generating an upward suction force in the host dust suction device 1. This suction force helps to suck the dust on the ground into the dust box during cleaning. During the process, the base station outgoing airflow of the dust collecting base station 300 is divided into two paths, which flow into the host dust collecting device 2 from the host air outlet channel 30 and the host air inlet channel 31 to form a circulating turbulent flow, or the host dust suction airflow flows through the reflection wall 306 of the dust collecting base station 300 from the host air inlet channel 31 to flow into the host dust collecting device 2 to form a circulating turbulent flow. The two form a circulating turbulent flow in the host dust collecting device 2 and cooperate with the base station dust suction airflow of the dust collecting base station 300 to transport the dust to the dust collecting base station 300 through the host dust outlet channel 4. Therefore, by forming a circulating turbulent flow in the host dust collecting device 2, the dilemma of airflow obstruction in the traditional structure is broken, so that the dust and garbage in the dust box are fully stirred up and no longer deposited at the bottom and corners, so that it is easier to be sucked into the base station dust box 303 by the dust suction airflow of the dust collecting base station 300 through the host dust outlet channel 4, which greatly improves the dust collection efficiency of the base station and realizes efficient cleaning of the sweeping machine 200.

At the same time, the open inclined structure of the dust suction port 25 can effectively prevent garbage from leaking from the dust suction port 25 during the dust collection process at the base station.

[0074] S2: Determine whether the reflective wall 306 connects the base station air blowing channel 305 with the host air duct module 3;

[0075] S3: If so, the host dust suction device 1 stops running, and the base station fan 302 starts running, and the base station outgoing airflow generated by the base station fan 302 flows into the host dust collecting device 2 through the base station blowing channel 305 through the host air outlet channel 30 and the host air inlet channel 31 to form a circulating turbulent flow, and the base station dust suction airflow sucks the objects to be collected in the host dust collecting device 2 into the base station dust box 303 through the host dust outlet channel 4 and the base station dust collecting channel 304;
