Referring to fig. 1, the present application provides a cleaning system, which includes a dust collecting pile and a sweeping robot, wherein the dust collecting pile is fixed on a surface to be cleaned, and the sweeping robot is controlled to be separated from or connected to the dust collecting pile. The cleaning system has a cleaning state that the sweeping robot is separated from the dust collecting pile, and a dust collecting state that the sweeping robot is connected with the dust collecting pile. When the cleaning system is in a cleaning state, the sweeping robot independently walks on the surface to be cleaned and performs cleaning operation on the surface to be cleaned. When the cleaning system is in a dust collecting state, the sweeping robot is connected with the dust collecting pile, and the dust collecting pile can collect garbage in the sweeping robot.

Specifically, the dust collecting pile comprises a dust collecting main body, a dust collecting fan and a dust collecting bag, wherein the dust collecting fan and the dust collecting bag are both connected with the dust collecting main body in an adapting mode, an air outlet channel and an air inlet channel are formed in the dust collecting main body, and the air inlet channel is communicated with the dust collecting bag. The sweeping robot comprises a machine body, a dust collection box and a dust box fan, wherein the dust box fan and the dust collection box are both connected to the machine body. When the cleaning system is in a cleaning state, the sweeping robot is separated from the dust collecting pile, the dust collecting fan is closed, the dust box fan is opened, and garbage on the surface to be cleaned is collected into the dust collecting box under the action of the dust box fan. When the cleaning system is in a dust collecting state, the machine body is connected with the dust collecting main body, and the dust collecting box is communicated between the air outlet channel and the air inlet channel. The dust box fan is closed, the dust collecting fan is opened, and under the action of the dust collecting fan, external air flows into the dust collecting box through the air outlet channel and carries garbage in the dust collecting box to flow into the dust collecting bag through the air inlet channel for collection.

Referring to fig. 2 and 3, the dust collecting box 1 includes a dust box body 10 and an air inlet baffle 20, a dust collecting chamber 11 is provided in the dust box body 10, the dust box body 10 is provided with a first air inlet 13, a second air inlet, a first air outlet 15 and a second air outlet, and the first air inlet 13, the second air inlet, the first air outlet 15 and the second air outlet are all communicated with the dust collecting chamber 11. The intake baffle 20 includes at least two sub-baffles 21, and each sub-baffle 21 is rotatably coupled to the dust box main body 10. Wherein each sub-shutter 21 is capable of rotating relative to the dust box body 10 by the force of the external air flow and opening the first air inlet 13 when the air inlet shutter 20 closes the first air inlet 13.

Specifically, when the cleaning system is in the cleaning state, the first air inlet 13 and the first air outlet 15 are both closed, and the second air inlet and the second air outlet are both opened. The dust collection fan is closed, the dust box fan is started, under the action of the dust box fan, the garbage on the surface to be cleaned can flow into the dust collection cavity 11 through the second air inlet along with the external air flow, and then is separated in the dust collection cavity 11. The separated external air flows out of the sweeping robot through the second air outlet, and the separated garbage is collected in the dust collection cavity 11. After the cleaning state is finished, the sweeping robot returns to the dust collecting pile, the machine body is connected with the dust collecting main body, and the cleaning system is switched to the dust collecting state. When the cleaning system is in a dust collecting state, the first air inlet 13 is communicated between the air outlet channel and the dust collecting cavity 11, and the air inlet channel is communicated between the first air outlet 15 and the dust collecting bag. At this time, the blower of the dust box is turned off, and external garbage cannot enter the dust collection chamber 11 through the second air inlet. The dust collection fan is started to drive the external air flow to flow out through the air outlet channel and open the air inlet baffle 20. Then, the outside air flows into the dust collecting chamber 11 from the first air inlet 13. Then, the external airflow carries the garbage in the dust collecting chamber 11 into the dust bag through the air inlet passage so that the garbage can be collected in the dust bag.

In the conventional sweeping robot, the air inlet baffle 20 is a single piece, and when the air inlet baffle 20 is pressed by the garbage, the air inlet baffle 20 cannot rotate and open the first air inlet 13 by the action of the external air flow. In the present application, the intake baffle 20 is divided into at least two sub-baffles 21. Since each of the sub-shutters 21 is rotatably connected to the dust box main body 10, when there is no rubbish pressed against any one of the sub-shutters 21, all of the sub-shutters 21 can be rotated inward by the external air flow and together fully open the first air inlet 13. When the partial sub barrier 21 is pressed by the garbage, the remaining partial sub barrier 21 which is not pressed can also open a part of the first air inlet 13 by the external air flow, so that the dust collection reliability and the dust collection efficiency of the cleaning system can be improved. Moreover, since the external air flow flows in from the first air inlet 13 and flows out from the first air outlet 15, the external air flow passes through the dust collection chamber 11, and compared with other modes of directly sucking away the garbage in the dust collection chamber 11 by negative pressure, the dust collection device has no dead angle for dust collection and has better dust collection effect.

As can be appreciated, since each sub-flapper 21 is smaller than the conventional intake flapper 20, the external air flow more easily pushes the single sub-flapper 21 to rotate, thereby enabling the first intake port 13 to be opened more quickly and easily. Therefore, the dust collecting case 1 has better dust collecting efficiency. In addition, since the single sub-baffle 21 has a small area, the leeward side thereof is less likely to generate a vortex flow in the process of the external air flowing into the dust collecting chamber 11, and thus, the wind loss is also small.

It is worth mentioning that due to the arrangement of the at least two sub-baffles 21, external air flow can be blown into the dust collection cavity 11 from multiple directions, so that dust collection dead corners can be avoided, and the cleaning system has a better dust collection effect.

Specifically, the number of the sub baffles 21 may be two or more, and the plurality of sub baffles 21 may be arranged side by side along a fixed direction, or may be arranged at intervals along the circumferential direction of the first air inlet 13, and it is only necessary to ensure that each sub baffle 21 can rotate inward under the action of the external air flow and open the first air inlet 13.

Referring to fig. 4, in some embodiments, the dust collecting box 1 further includes at least two air inlet rotating shafts 30, all the air inlet rotating shafts 30 correspond to all the sub-baffles 21 one by one, and each air inlet rotating shaft 30 is rotatably inserted through the corresponding sub-baffle 21 and is fixedly connected to the wall edge of the first air inlet 13. Each of the sub-shutters 21 is rotated inward about the intake rotation shaft 30 corresponding thereto by the external air flow to fully open the first intake port 13. The way that each sub-baffle 21 is rotatably connected with the dust box main body 10 through the corresponding air inlet rotating shaft 30 is simple, so that the assembly efficiency of the dust box 1 is improved conveniently.

Of course, in other embodiments, the manner in which each sub-shutter 21 is pivotally connected to the dust box body 10 is not limited to the above-mentioned one. For example, the sub-baffle 21 and the main dust box 10 may be rotatably connected by a spherical pair, a hinge, or other means.

In some embodiments, the main body 10 further includes at least two receiving ribs 17, and all the receiving ribs 17 correspond to all the sub-baffles 21 one to one. Each sub-baffle 21 has a rotating end and a movable end which are oppositely arranged, the rotating end of each sub-baffle 21 is rotatably connected with the dust box main body 10, and when the air inlet baffle 20 closes the first air inlet 13, the movable end of each sub-baffle 21 is connected with the corresponding receiving rib 17. That is, when the intake damper 20 completely closes the first intake port 13, the movable end of each sub-damper 21 can be received above the receiving rib 17 corresponding thereto. Under the action of the adaptor and the air inlet rotating shaft 30, when the air inlet baffle 20 closes the first air inlet 13, each sub-baffle 21 cannot rotate to the outside of the dust collection cavity 11, so that the reliability of closing the first air inlet 13 is ensured. In this way, when the cleaning system is in a cleaning state, it is helpful to prevent the garbage in the dust collection chamber 11 from leaking to the outside from the first air inlet 13, which results in poor cleaning effect.

Furthermore, a first air outlet 15 communicated with the dust collection chamber 11 is formed in the dust box main body 10, and all the receiving ribs 17 and all the sub-baffles 21 are arranged at intervals along the direction of a connecting line between the first air outlet 15 and the first air inlet 13. When the air inlet baffle 20 closes the first air inlet 13, the movable end of the sub-baffle 21 farthest from the first air outlet 15 is far away from the first air outlet 15 relative to the rotating end. Therefore, when the cleaning system is in the dust collecting state, the sub-barrier 21 farthest from the first air outlet 15 can be rotated by the external air flow and open the first air inlet 13. Further, the outside air flow may be blown toward the end face farthest from the first air outlet 15 in the direction of the line connecting the first air outlet 15 and the first air inlet 13, guided by the sub-damper 21 farthest from the first air outlet 15. Furthermore, along with the flowing of the air flow, the garbage between the two oppositely arranged end surfaces in the connecting line direction of the first air outlet 15 and the first air inlet 13 can be thoroughly removed, so that the cleaning system has a better dust collecting effect. Specifically, the path of the external air flowing in through the first air inlet 13 and flowing out from the first air outlet 15 through the dust collecting chamber 11 is as indicated by arrows in fig. 2 and 3.

Preferably, when the intake damper 20 closes the first intake port 13, the movable end of each sub-damper 21 is away from the first outlet port 15 with respect to the rotating end. Therefore, the external air flow can be blown to the end surface farthest from the first air outlet 15 in the direction of the line connecting the first air outlet 15 and the first air inlet 13 by the guidance of each sub-barrier 21, so that the dust collecting effect of the cleaning system can be further improved.

Of course, in other embodiments, when the intake baffle 20 closes the first intake port 13, there may be a portion of the rotating ends of the sub-baffles 21 disposed away from the first outlet port 15 compared to the respective movable ends, and the remaining portion of the movable ends of the sub-baffles 21 disposed away from the first outlet port 15 compared to the respective rotating ends.

In some embodiments, the dust collecting box 1 further comprises at least two restoring members 40, all of the restoring members 40 correspond to all of the sub-baffles 21 one by one, and each restoring member 40 is drivingly connected between the corresponding sub-baffle 21 and the dust box main body 10 and is configured to provide a restoring force for driving the sub-baffles 21 to cover the first air inlet 13. When the dust collecting fan stops working, each sub baffle plate 21 can rotate under the action of the corresponding resetting piece 40 until the movable end of each sub baffle plate 21 is received on the corresponding receiving rib 17. That is, the intake damper can automatically close the first intake port 13. Thus, when the cleaning system is in a cleaning state, it helps to prevent the garbage in the dust collecting chamber 11 from leaking to the outside through the first air inlet 13, thereby ensuring a superior cleaning effect of the cleaning system.

Preferably, the restoring member 40 is a torsion spring, one side of each sub-baffle 21 connected to the air inlet rotating shaft 30 is provided with a position-avoiding opening 212, each restoring member 40 is located in the position-avoiding opening 212, and each restoring member 40 is sleeved on the corresponding air inlet rotating shaft 30 and abuts against the dust box main body 10 and the sub-baffle 21. Each sub flapper 21 automatically covers the first air inlet 13 by the torsional force of the restoring member 40. By disposing each restoring member 40 in the corresponding avoiding opening 212, each restoring member 40 does not occupy additional space. On one hand, the blocking of each resetting piece 40 to the external air flow can be reduced, so that the external air flow can smoothly flow into the dust collection cavity 11 and act, and the sweeping robot has better dust collection efficiency and dust collection efficiency. On the other hand, the beauty and the compactness of the structure of the dust collecting case 1 can be improved.

Of course, in other embodiments, the specific configuration of reducing element 40 is not limited to the one described above. For example, the restoring member 40 may be a compression spring or an extension spring, and each of the sub-barriers 21 may automatically cover the first air inlet 13 under the compression force or the extension force of the restoring member 40.

Referring to fig. 5, the dust collecting box 1 further includes an air outlet baffle 50, and the dust box body 10 is provided with a first air outlet 15 communicated with the dust collecting chamber 11. When the inlet baffle 20 closes the first inlet 13 and the outlet baffle 50 closes the first outlet 15, the garbage in the dust collecting chamber 11 can be prevented from leaking to the outside through the first outlet 15 to pollute the external environment again when the cleaning system is in a cleaning state. Therefore, the sweeping robot has a better cleaning effect. When at least one sub-flapper 21 rotates and opens a portion of the first inlet port 13, the outlet flapper 50 opens the first outlet port 15. Therefore, the garbage in the dust collecting chamber 11 can be collected in the dust collecting bag by the external air flow.

Preferably, the air outlet baffle 50 is rotatably connected to the dust box body 10. The air outlet baffle 50 opens or closes the dust removal port by rotating. Specifically, the air outlet baffle 50 can be rotatably connected to the main dust box 10 via an air outlet shaft 70, a spherical pair, a hinge, or other structures.

Preferably, the dust collecting box 1 further comprises an elastic member 60, and the elastic member 60 is used for providing a driving force for driving the air outlet baffle 50 to close the first air outlet 15. When the dust collection is finished, the dust collection fan stops working, the air outlet baffle 50 can automatically close the first air outlet 15 under the action of the elastic element 60, and therefore when the cleaning system is in a cleaning state, the garbage in the dust collection cavity 11 can be prevented from leaking to the outside through the first air outlet 15.

Specifically, the elastic member 60 may be a torsion spring, a compression spring, an extension spring, or the like. It is only necessary to ensure that the elastic member 60 can drive the air outlet baffle 50 to automatically close the first air outlet 15.

According to the dust collection box 1, the sweeping robot and the cleaning system, the air inlet baffle plate 20 is divided into at least two sub baffle plates 21, and each sub baffle plate 21 is rotatably connected with the dust collection box main body 10, so that when no garbage presses any sub baffle plate 21, all the sub baffle plates 21 can rotate under the action of external air flow and open the first air inlet 13 together. When the partial sub-baffles 21 are pressed by the garbage, the remaining partial sub-baffles 21 which are not pressed can also open partial first air inlets 13 under the action of the external air flow, so that the dust collection reliability and the dust collection efficiency of the dust collection box 1, the sweeping robot and the cleaning system can be improved.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several embodiments of the present application, and the description thereof is more specific and detailed, but not construed as limiting the claims. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the concept of the present application, which falls within the scope of protection of the present application.
