[0029] Further, the switching sewage suction device of the cleaning robot includes a vehicle body 10, a dust collection component 20, a sewage suction component 30, an adjustment component 40, and a storage box 50. Among them, the dust collection component 20, the sewage suction component 30, the adjustment component 40, and the storage box 50 are arranged on the vehicle body 10. The dust collection component 20 collects the dust on the ground to be cleaned, the sewage suction component 30 absorbs the sewage and dirt generated by cleaning the ground. The dust collection component 20 and the sewage suction component 30 are respectively connected to the storage box 50 through the adjustment component 40. Through the adjustment component 40, the dust collection component 20 and the sewage suction component 30 are respectively switchably communicated with the storage box 50. The dust collection component 20 and the sewage suction component 30 alternately convey dust or sewage to the storage box 50, so that the dust collection component 20 does not need to be manually cleaned regularly, the operation time of the cleaning robot is sufficient, and the cleaning completion degree is relatively high.

[0030] Further, the dust collection assembly 20 includes a front sweeping member 21 and a dust box 22. The front sweeping member 21 is connected to the dust box 22. The dust box 22 collects various dusts and dirt swept by the front sweeping member 21. The front sweeping member 21 is disposed at the bottom of the vehicle body 10 and in the forward direction of the vehicle body 21. The front sweeping member 21 can directly contact the ground to sweep the dust. The dust box 22 is disposed at the bottom of the vehicle body 10 and is correspondingly arranged with the front sweeping member 21, facilitating the collection of the dust swept by the front sweeping member 21. The dust box 22 has a small volume, which is beneficial for installation, saves the assembly cost, and is conducive to reducing the volume of the cleaning robot, facilitating the cleaning work.

[0031] Further, the dust collection assembly 20 further includes a dust collection pipe 23. The dust collection pipe 23 is disposed between the dust box 22 and the storage box 50. The dust box 22 is connected to the storage box 50 through the dust collection pipe 23. After the dust box 22 collects dust for a preset time or a preset capacity, the dust and other substances are transported to the storage box 50 through the dust collection pipe 23, enabling the dust box 22 to continuously collect dust, enabling the front sweeping member 21 to continuously work, eliminating the need for staff to regularly clean the dust box 22, saving time costs, and improving the cleaning efficiency.

[0032] Further, the dust box 22 has a dust collection port 221. The dust collection port 221 is disposed at the top of the dust box 22. The dust collection pipe 23 connects the dust box 22 and the storage box 50 through the dust collection port 221.

[0033] Preferably, the front sweeping member 21 is a roller brush.

[0034] Preferably, the rear washing member 31 is a rear washing roller brush.

[0035] Further, the sewage suction assembly 30 includes a rear washing member 31. The rear washing member 31 is disposed at the rear of the bottom of the vehicle body 10 and is correspondingly arranged with the front sweeping member 21. The front sweeping member 21 sweeps in the dust, and the rear washing member 31 sprays water and cleans the ground for further cleaning work. The rear washing member 31 can deeply clean the ground and suck up the sewage on the ground. The rear washing member 31 is connected to the storage box 50, and the rear washing member 31 sucks up the sewage on the ground and transports it to the storage box 50.

[0036] Further, the sewage suction assembly 30 further includes a sewage suction pipe 32. The sewage suction pipe 32 is disposed between the rear washing member 31 and the storage box 50. The rear washing member 31 is connected to the storage box 50 through the sewage suction pipe 32. The rear washing member 31 transports sewage and the like to the storage box 50 through the sewage suction pipe 32.

[0037] Further, the storage box 50 is provided on the vehicle body 10, the dust box 21 and the rear cleaning member 31 are respectively communicated with the storage box 50, and the storage box 50 houses dust, sewage, etc. generated after the cleaning robot cleans the ground. It should be noted that the dust box 21 and the rear cleaning member 31 alternately transport garbage to the storage box 50.

[0038] Further, the adjustment assembly 40 includes a first switching valve 41 and a second switching valve 42. The first switching valve 41 is provided on the dust collection pipe 23, and the second switching valve 42 is provided on the sewage suction pipe 32. The first switching valve 41 and the second switching valve 42 respectively control the communication states of the dust collection pipe 23 and the sewage suction pipe 32 with the storage box 50, and the first switching valve 41 and the second switching valve 42 enable the dust collection pipe 23 and the sewage suction pipe 32 to alternately transport garbage to the storage box 50.

[0039] Preferably, the first switching valve 41 and the second switching valve 42 can be, but are not limited to, direct-through switching valves and rotary switching valves.

[0040] Preferably, the storage box 50 is a sewage box.

[0041] In a specific implementation scenario, during the working state, the front cleaning member 21 is driven to rotate by the motor system of the vehicle body 10, and the garbage is swept into the dust box 22. When the garbage in the dust box 22 accumulates to a certain extent, the garbage in the dust box 22 is collected through the dust collection port 221 and sucked into the storage box 50 through the dust collection pipe 23.

[0042] In the first working state, the first switching valve 41 is in the closed state, and the second switching valve 42 is in the open state. At this time, there is no air volume in the dust collection pipe 23, and the dust collection pipe 23 does not perform the dust collection action. The front cleaning member 21 independently cleans the garbage, and the garbage is swept into the dust box 22 and does not enter the dust collection pipe 23. At this time, there is a strong air volume in the sewage suction pipe 32, and the sewage suction pipe 32 performs the action of sucking sewage. The rear cleaning member 31 independently washes the ground and sucks sewage, and the rear cleaning member 31 transports the sewage to the storage box 50 through the sewage suction pipe 32. At this time, the cleaning robot normally realizes the integrated sweeping and washing work.

[0043] When the dust box 22 collects a certain amount of garbage through the front sweeping member 21, the cleaning robot switches from the first working state to the second working state. The first switching valve 41 switches to the open state, and the second switching valve 42 switches to the closed state. At this time, there is a strong air volume in the dust collection pipe 23, and the garbage in the dust box 22 is collected into the storage box 50. There is no air volume in the sewage suction pipe 32, and the floor washing and sewage suction actions stop. The integrated sweeping and washing work of the cleaning robot pauses. After the garbage in the dust box 22 is collected into the storage box 50, the first switching valve 41 switches to the closed state, and the second switching valve 42 switches to the open state. The cleaning robot switches from the second working state to the first working state and starts the integrated sweeping and washing work.

[0044] The cleaning robot of the present utility model only needs to be provided with one storage box 50, and two suction and sewage working modes are switched through the control of two air paths. The dust collection assembly 20 is provided with a relatively small dust box 22. In the first working state, the integrated sweeping and washing work can be carried out, and the garbage is temporarily stored in the dust box 22. When the garbage in the dust box 22 is collected to a certain extent, the floor washing mode is closed and the dust collection mode is entered. The dust collection mode is a short-term behavior and will not affect the overall cleaning efficiency. By sharing one storage box 50, the assembly size space of the cleaning robot can be greatly reduced, the space occupancy rate of the cleaning robot can be improved, and the staff does not need to regularly clean the dust box 22, which is beneficial to the improvement of the cleaning efficiency.
