[0025] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope protected by the present application.

[0026] The inventor of the present application has found through long-term research that cleaning devices often need to clean garbage objects in the environment during the cleaning process to keep the environment clean. For example, air flow can be generated by a fan to suck dust and debris in the environment. However, in the prior art, the cleaning actions of cleaning devices are relatively single, resulting in limited cleaning scenarios for cleaning devices. To solve this technical problem, the following embodiments are provided in the present application.

[0027] Such as Figures 1 to 3 and Figure 8As shown in the figure, the cleaning system described in the embodiment of the present application's cleaning system includes a self - propelled cleaning device 1 and a base station 300. The self - propelled cleaning device 1 is provided with a dust collection chamber 201. The function of the dust collection chamber 201 is to collect various garbage objects sucked by the self - propelled cleaning device 1 during the cleaning work, such as dust particles, paper scraps, hair, etc. The base station 300 is provided with a dust collection port 301, and the dust collection port 301 is used to communicate with the dust collection chamber 201.

[0028] Further, the self - propelled cleaning device 1 is provided with a dust removal port 203. When the self - propelled cleaning device 1 is docked with the base station 300, the garbage objects collected in the dust collection chamber 201 can enter the base station 300 through the dust removal port 203 and the dust collection port 301.

[0029] Specifically, the self - propelled cleaning device 1 can have one or more functions such as sweeping, mopping, floor washing, and vacuuming. For example, the self - propelled cleaning device 1 can be a sweeping robot, a mopping robot, a mopping and washing integrated robot, a sweeping, mopping and washing integrated robot, etc. When the self - propelled cleaning device 1 is performing cleaning work, the self - propelled cleaning device 1 can suck various garbage objects from the outside, such as dust particles, paper scraps, hair, etc.

[0030] As Figures 3 to 5 shown, and as Figures 9 to 12 shown, the self - propelled cleaning device 1 can include a device main body 100 and a fan 209.

[0031] The device main body 100 can also include a main shell 124, a traveling component, and a cleaning component 126. The main shell 124 can serve as the overall structural framework of the device main body 100. The inside of the main shell 124 can be used to accommodate multiple functional components, electrical devices, and other components to protect the internal elements and structures of the self - propelled cleaning device 1, etc.

[0032] The traveling component can be mainly arranged in the main shell 124. The traveling component can enable the self - propelled cleaning device 1 to have the functions of being movable and self - propelled, so that the self - propelled cleaning device 1 can automatically go to the area that needs to be cleaned for cleaning. The traveling component includes a driving wheel 125 and a universal wheel 1251, and the universal wheel 1251 is driven by the driving wheel 125 to move. The cleaning component 126 can include a rotary brush. The rotary brush can be arranged at the bottom of the main shell 124 and is used to provide a cleaning function when the self - propelled cleaning device 1 is working, and clean the working surface of the self - propelled cleaning device 1. The fan 209 is used to suck garbage objects such as dust and debris on the working surface into the dust collection chamber 201.

[0033] The cleaning component 126 and the fan 209 can cooperate with each other and work together. For example, the dust suction port 101 can be arranged adjacent to the rotary brush, so that the garbage or dust swept out during the rotation of the rotary brush can be sucked into the dust collection chamber 201.

[0034] The structure of the above-mentioned self - propelled cleaning device 1 is only for illustrative purposes and is not limited to the above - mentioned exemplary structure.

[0035] Optionally, as Figure 1 shown, the base station 300 may include a base - station main body 310 and a base 30. The base - station main body 310 and the base 30 are connected. For example, the base - station main body 310 may be disposed on one side of the base 30, or the base - station main body 310 may be disposed above the base 30. The base 30 can be used to carry the self - propelled cleaning device 1. For example, the self - propelled cleaning device 1 can travel to the base 30 and stay on the base 30. The base - station main body 310 can suck the garbage in the self - propelled cleaning device 1 carried on the base 30. In some embodiments, the base station 300 may not be configured with the base 30 either.

[0036] Optionally, the base station 300 may have a dust collection box 23, a sewage box 24, a dust collection fan 320, a pumping mechanism 26, a liquid supply mechanism 27, and a gas supply mechanism 28. Specifically, the base - station main body 310 has a dust collection box 23, a clean water tank 21, a sewage box 24, a dust collection fan 320, a pumping mechanism 26, a liquid supply mechanism 27, and a gas supply mechanism 28. Further, the base - station main body 310 may also have a first housing 29. The clean water tank 21, the dust collection box 23, the sewage box 24, and the gas supply mechanism 28 may be disposed in the first housing 29 and are spaced apart from each other. The dust collection fan 320 is used to suck the garbage in the self - propelled cleaning device 1 into the dust collection box 23. The dust collection box 23 is used to retain the garbage sucked from the self - propelled cleaning device 1. The sewage box 24 is used to hold the sewage or waste liquid generated after cleaning the self - propelled cleaning device 1. The pumping mechanism 26 is used to pump the sewage generated after cleaning the self - propelled cleaning device 1 into the sewage box 24. The pumping mechanism 26 can also be connected to the sewer pipe in the scene to be cleaned to automatically pump the sewage into the sewer pipe. The liquid supply mechanism 27 is used to transport or pump the cleaning liquid to the self - propelled cleaning device 1. The gas supply mechanism 28 is used to provide dry gas, so as to be able to dry the corresponding area of the self - propelled cleaning device 1 after cleaning. In other embodiments, the sewage recovery and the collection of dry garbage can share a power source, that is, only one of the dust collection fan 320 and the pumping mechanism 26 may be provided. In addition, in some embodiments, the gas supply mechanism 28 may also be omitted.

[0037] Optionally, the base station 300 may include a dust bag, and the dust bag is disposed in the dust collection box 23, and the garbage entering the base station will finally enter the dust bag. Alternatively, the dust collection box 23 can also use a cyclone separator to achieve gas - dust separation.

[0038] Regarding the self - propelled cleaning device 1 described in the embodiments of the cleaning system of the present application, the following content can be specifically referred to.

[0039] As Figures 2 to 5As shown, the self - propelled cleaning device 1 includes drive wheels 125, a device main body 100, and a handheld dust suction device 200. The handheld dust suction device 200 is detachably connected to the device main body 100. The drive wheels 125 are installed on the device main body 100 and are used to drive the device main body 100 to move on the working surface. The handheld dust suction device 200 includes a handle 241 and a blower 209. The handheld dust suction device 200 is formed with a dust collection chamber 201, an air inlet 202, and a dust removal port 203 that communicates with the dust collection chamber 201. The device main body 100 is provided with a dust suction port 101, and the dust suction port 101 communicates with the air inlet 202. The blower 209 has an air inlet 2091 that communicates with the dust collection chamber 201. The blower 209 is used to form an air flow that flows from the dust suction port 101 through the air inlet 202 into the dust collection chamber 201. The dust collection chamber 201 is used to accommodate the garbage objects carried by the air flow. The base station 300 is provided with a dust collection port 301. The dust collection port 301 is used to communicate with the dust removal port 203 so that the garbage objects in the dust collection chamber 201 can enter the base station 300 through the dust removal port 203 and the dust collection port 301.

[0040] After the handheld dust suction device 200 is detached from the device main body 100, the handheld dust suction device 200 can be used separately by the user holding it to suck garbage objects. Specifically, after being detached from the device main body 100, when the handheld dust suction device 200 works, it can form an air flow that flows into the handheld dust suction device 200 through the air inlet 202, and then transports the garbage objects carried by the air flow through the air inlet 202 to the dust collection chamber 201.

[0041] When the handheld dust suction device 200 is assembled to the device main body 100, the handheld dust suction device 200 and the device main body 100 can cooperate to suck garbage objects. Specifically, when the handheld dust suction device 200 is assembled to the device main body 100, the dust suction port 101 communicates with the air inlet 202. When the handheld dust suction device 200 works, it forms an air flow that flows from the dust suction port 101 through the air inlet 202 into the handheld dust suction device 200, and then transports the garbage objects carried by the air flow through the dust suction port 101 and the air inlet 202 to the dust collection chamber 201.

[0042] In some embodiments, when both the handheld dust suction device 200 and the device main body 100 are in a working state, the formed air flow can enter the interior of the device main body 100 from the dust suction port 101, and then flow into the handheld dust suction device 200 through the air inlet 202 and transport the garbage objects carried by the air flow to the dust collection chamber 201.

[0043] By setting the handheld vacuum device 200 such that the dust suction port 101 communicates with the air inlet 202 when the handheld vacuum device 200 is assembled to the device main body 100, the dust collection chamber 201 can be used independently by the handheld vacuum device 200 and can also be used when the handheld vacuum device 200 is assembled to the self-propelled cleaning device 1 of the device main body 100, which can save space, improve the space utilization rate of the self-propelled cleaning device 1, and the saved space can be used to set parts that can enhance the cleaning function to improve the cleaning effect. For example, the saved space can be used to set a power supply component 221 with a larger energy storage capacity to improve the battery life of the self-propelled cleaning device 1. In addition, the user can selectively use the self-propelled cleaning device 1 and the handheld vacuum device 200 according to different household scenarios. For example, the self-propelled cleaning device 1 is used to clean the ground, and the handheld vacuum device 200 is used to clean areas above the ground that the self-propelled cleaning device 1 cannot cross, such as tabletops, steps, etc. Of course, the handheld vacuum device 200 can also be used to clean the cleaning dead corners of the self-propelled cleaning device 1, such as the corners of the wall, etc.

[0044] As Figures 3 to 6 shown, the dust removal port 203 can be spaced from the air inlet 202. The dust removal port 203 is used to communicate with the dust collection port 301 of the base station 300 when the self-propelled cleaning device 1 is docked with the base station 300, so that the garbage objects in the dust collection chamber 201 can be sucked into the base station 300 through the dust removal port 203 and the dust collection port 301.

[0045] For example, in the state where the handheld vacuum device 200 is assembled to the device main body 100, during the dust collection process of the base station 300, the airflow formed by the base station 300 can flow into the dust collection chamber 201 through the air inlet 202, and then leave the dust collection chamber 201 through the dust removal port 203 and enter the base station 300 through the dust collection port 301. The airflow is used to carry the garbage objects in the dust collection chamber 201 when flowing through the dust collection chamber 201, so as to collect the garbage objects in the dust collection chamber 201 into the base station 300. A dust collection box 23 or a dust bag can be provided in the base station 300 to accommodate the garbage objects from the dust collection chamber 201.

[0046] In some embodiments, the dust collection port 301 communicates with the dust removal port 203 in a docking manner.

[0047] Optionally, as Figures 3 to 6 shown, the device main body 100 is provided with a dust outlet 102 communicating with the dust suction port 101. The dust outlet 102 is used to communicate with the air inlet 202 when the handheld vacuum device 200 is assembled to the device main body 100. Further, the dust outlet 102 is used to dock and communicate with the air inlet 202 when the handheld vacuum device 200 is assembled to the device main body 100.

[0048] When the handheld dust suction device 200 is assembled to the device main body 100, the airflow formed during the operation of the handheld dust suction device 200 can enter the interior of the device main body 100 from the dust suction port 101, then flow out from the dust outlet 102, and then enter the dust collection chamber 201 inside the handheld dust suction device 200 through the air inlet 202, and convey the garbage objects carried by the airflow to the dust collection chamber 201 to achieve the cleaning function.

[0049] Optionally, as Figure 3 shown, the device main body 100 is provided with a dust discharge port 103 and a dust inlet 104 that communicate with each other. The dust discharge port 103 is used to communicate with the dust collection port 301, and the dust inlet 104 is used to communicate with the dust removal port 203. Further, the dust discharge port 103 is used to dock and communicate with the dust collection port 301, and the dust inlet 104 is used to dock and communicate with the dust removal port 203.

[0050] When the handheld dust suction device 200 is assembled to the device main body 100, during the dust collection process of the base station 300, the airflow formed by the base station 300 can successively flow into the dust collection chamber 201 through the dust suction port 101 and the air inlet 202, then leave the dust collection chamber 201 through the dust removal port 203 and enter the device main body 100 through the dust inlet 104, and then enter the base station 300 through the dust discharge port 103 and the dust collection port 301. The airflow is used to carry the garbage objects in the dust collection chamber 201 when flowing through the dust collection chamber 201, so that the garbage objects in the dust collection chamber 201 can be collected into the base station 300.

[0051] By arranging the dust discharge port 103 on the device main body 100 instead of the handheld dust suction device 200, the compatibility of the base station 300 with different self - propelled cleaning devices 1 can be improved. When adjusting the assembly relationship between the handheld dust suction device 200 and the device main body 100, the docking structure between the base station 300 and the device main body 100 can be kept unchanged, which is beneficial to realizing the stable docking between the dust discharge port 103 and the dust collection port 301.

[0052] Optionally, as Figure 2 and Figure 4 shown, the handheld dust suction device 200 is provided with a shielding member 210. The shielding member 210 is movably arranged at the dust removal port 203 so as to be able to switch between a covering position and an open position relative to the dust removal port 203. The shielding member 210 is arranged to cover the dust removal port 203 in the covering position, and is also arranged to move from the covering position to the open position to open the dust removal port 203 under the attraction of the dust collection fan 320.

[0053] When the self - propelled cleaning device 1 is performing cleaning work or the hand - held dust - suction device 200 is held for cleaning work after being detached from the device main body 100, the shielding member 210 can cover the dust - removal port 203 in the covering position, thereby preventing garbage objects from leaving the dust - collection cavity 201 through the dust - removal port 203. When the self - propelled cleaning device 1 needs to collect dust, under the suction force of the dust - collection fan 320, the shielding member 210 can be in the open position to open the dust - removal port 203, and the airflow formed under the action of the dust - collection fan 320 can carry the garbage objects to leave the dust - collection cavity 201 through the dust - removal port 203 and enter the base station 300, thereby realizing the dust - collection function.

[0054] Optionally, the hand - held dust - suction device 200 is provided with an elastic member, and the shielding member 210 is rotatably arranged at the dust - removal port 203. The elastic member is used to limit the shielding member 210 in the covering position, and the elastic member is in an elastically compressed state when the shielding member 210 is in the open position.

[0055] When the self - propelled cleaning device 1 is performing cleaning work or the hand - held dust - suction device 200 is held for cleaning work after being detached from the device main body 100, the elastic member can press the shielding member 210 to the covering position to cover the dust - removal port 203. When the self - propelled cleaning device 1 needs to collect dust, under the suction force of the dust - collection fan 320, the shielding member 210 rotates to the open position, and at the same time the elastic member is in an elastically compressed state. When the dust - collection of the self - propelled cleaning device 1 is completed, the dust - collection fan 320 stops working, and the elastic member elastically returns, causing the shielding member 210 to rotate to the covering position. For example, the elastic member is a torsion spring.

[0056] In some embodiments, the shielding member 210 is arranged to move to the covering position under the attraction of the fan 209. In some embodiments, the shielding member 210 is arranged to move to the covering position under the combined action of the attraction of the fan 209 and the elastic return of the elastic member. In some embodiments, the elastic member can also be omitted, and the shielding member 210 itself is made of an elastic material. For example, the shielding member 210 can be made of rubber material. In some embodiments, the shielding member 210 can also be arranged to move between the covering position and the open position under the drive of a motor.

[0057] Optionally, as Figure 6 and Figure 7 shown, the device main body 100 is provided with a first electrical connection part 110, and the hand - held dust - suction device 200 is provided with a second electrical connection part 220. When the hand - held dust - suction device 200 is assembled to the device main body 100, the first electrical connection part 110 and the second electrical connection part 220 are electrically connected.

[0058] The device main body 100 and the hand - held dust - suction device 200 can be electrically connected through the first electrical connection part 110 and the second electrical connection part 220, so as to realize power transmission and electrical signal transmission between the device main body 100 and the hand - held dust - suction device 200.

[0059] Optionally, as Figure 4 shown, the hand-held suction device 200 further includes a power supply component 221, and the power supply component 221 is electrically connected to the second electrical connection part 220 and the fan 209 respectively. The power supply component 221 is used to supply power to the device main body 100 when the second electrical connection part 220 is electrically connected to the first electrical connection part 110. The power supply component 221 can also be used to supply power to the fan 209.

[0060] Furthermore, as Figure 11 shown, the second electrical connection part 220 and the first electrical connection part 110 are electrically connected by means of plugging or elastic abutting.

[0061] Specifically, the second electrical connection part 220 and the first electrical connection part 110 are respectively one of a male seat and a female seat of a connecting PIN.

[0062] By arranging the power supply component 221 on the hand-held suction device 200, the power supply component 221 can supply power to the hand-held suction device 200 when the hand-held suction device 200 is held and used after being detached from the device main body 100, and can also supply power to the self-propelled cleaning device 1 when the hand-held suction device 200 is assembled to the device main body 100, which can make the layout of the self-propelled cleaning device 1 more compact.

[0063] In some other embodiments, a power supply component 221 is detachably arranged on the device main body 100, and the power supply component 221 can supply power to the self-propelled cleaning device 1. The power supply component 221 can be detached from the device main body 100 and then assembled to the hand-held suction device 200 to supply power when the hand-held suction device 200 is held and working after being detached from the device main body 100. Or, in some embodiments, batteries can be respectively arranged on the device main body 100 and the hand-held suction device 200. When the hand-held suction device 200 is assembled to the device main body 100, the two batteries are connected in series. When the hand-held suction device 200 is detached from the device main body 100, the two batteries can work independently.

[0064] Optionally, when the self-propelled cleaning device 1 is docked with the base station 300, the base station 300 can charge the power supply component 221.

[0065] Optionally, as Figure 2 and Figure 6 shown, the device main body 100 is provided with a recessed groove 105, and the hand-held suction device 200 is detachably arranged in the recessed groove 105.

[0066] By providing the recessed groove 105, it is convenient to assemble the hand-held suction device 200 on the device main body 100. The recessed groove 105 can play a role in limiting the hand-held suction device 200, which is beneficial to improving the connection stability between the hand-held suction device 200 and the device main body 100.

[0067] Optionally, as shown in Figure 2 and Figure 6 shown, the device main body 100 includes a limiting post 106 disposed in the recessed groove 105. The handheld vacuuming device 200 is provided with a limiting groove 204 that cooperates with the limiting post 106. The limiting post 106 is used to insert into the limiting groove 204 so as to be able to limit the handheld vacuuming device 200 in the recessed groove 105.

[0068] By providing the limiting post 106 and the limiting groove 204, the assembly positioning and limiting fixation of the handheld vacuuming device 200 and the device main body 100 can be performed, which is beneficial to improving the connection stability between the handheld vacuuming device 200 and the device main body 100.

[0069] Furthermore, as shown in Figure 6 shown, the handheld vacuuming device 200 includes a device main body 240 and a handle 241. The handle 241 and the device main body 240 enclose to form the limiting groove 204. The user's finger can extend into the limiting groove 204 to hold the handle 241.

[0070] Optionally, as shown in Figure 4 and Figure 6 shown, the limiting post 106 is provided with a hook portion 107. The groove wall of the limiting groove 204 is provided with a buckle groove 205. The hook portion 107 is used to be embedded in the buckle groove 205 when the limiting post 106 is inserted into the limiting groove 204, so that the handheld vacuuming device 200 is buckled to the device main body 100.

[0071] With such a setting, the separation of the handheld vacuuming device 200 and the device main body 100 can be restricted, which is beneficial to improving the connection stability between the handheld vacuuming device 200 and the device main body 100.

[0072] Furthermore, a part of the groove wall of the handle 241 forms the limiting groove 204, and the buckle groove 205 is provided on the handle 241. Or, as shown in Figure 11 shown, a part of the groove wall of the device main body 240 forms the limiting groove 204, and the buckle groove 205 is provided on the device main body 240.

[0073] Optionally, the hook portion 107 protrudes from the side surface of the limiting post 106. The insertion direction of the hook portion 107 into the buckle groove 205 intersects with the extending direction of the limiting post 106. Furthermore, the limiting post 106 extends along the height direction D4 of the self-propelled cleaning device 1.

[0074] Furthermore, the device body 100 includes an unlocking mechanism 109, which is movably disposed on the limiting column 106 and exposed to the outside. The unlocking mechanism 109 is used to be pressed to drive the hook portion 107 to disengage from the buckle groove 205, so that the handheld vacuum device 200 and the device body 100 are released from the buckle connection. Furthermore, the unlocking mechanism 109 is disposed on the top surface of the limiting column 106 facing upwards, so that the user can press it.

[0075] In this way, the unlocking mechanism 109 can be located close to the handle 241. When the user removes the handheld vacuum cleaner 200 from the device body 100, the user can press the unlocking mechanism 109 with one hand and hold the handle 241, thereby facilitating the user to remove the handheld vacuum cleaner 200 from the device body 100.

[0080] ​​​​​​Specifically, the recessed groove 105 is connected to the outside through the extension opening 1051. Part of the handheld vacuum device 200 can be located in the extension opening 1051. For example, the bottom wall of the recessed groove 105 is provided with the extension opening 1051.

[0081] Such a configuration is conducive to making the layout of the self-propelled cleaning device 1 more compact and reducing the height of the self-propelled cleaning device 1. In addition, the extension port 1051 is located below the air inlet 202. When the handheld vacuum device 200 is removed from the device body 100, the dust and garbage falling from the air inlet 202 can fall to the outside through the extension port 1051, which is convenient for the user to clean it up with the handheld vacuum device 200 or the self-propelled cleaning device 1, thereby avoiding the accumulation of dust and garbage in the recessed groove 105 and requiring the user to clean it up manually.

[0082] Furthermore, part of the handheld vacuum cleaner 200 can extend to the outside through the extension opening 1051. Specifically, the walking mechanism has the function of supporting the device body 100 to form a spacing space at the bottom 122 of the device body 100, so that the device body 100 and the working surface (such as the ground) are spaced apart, and the recessed groove 105 can be connected to the spacing space through the extension opening 1051, and part of the handheld vacuum cleaner 200 can extend into the spacing space through the extension opening 1051. Such a configuration is conducive to further reducing the height size of the self-propelled cleaning device 1. In some embodiments, the extension opening 1051 can also be omitted.

[0083] Furthermore, the extension direction of the limiting column 106 is parallel to the recessed direction of the recessed groove 105.

[0084] Optionally, such as Figure 6 As shown, the device body 100 has a head 128 facing the forward direction of the self-propelled cleaning device 1 and a tail 129 away from the forward direction. The handheld vacuum cleaner 200 is detachably arranged on the tail 129 and exposed to the outside. This arrangement can make the center of gravity layout of the device body 100 more compact and reasonable, and at the same time facilitate the installation and removal of the handheld vacuum cleaner 200 on the device body 100. Among them, the forward direction of the self-propelled cleaning device 1 refers to the forward direction of the self-propelled cleaning device 1 when it walks to clean the scene to be cleaned.

[0085] Optionally, the dust outlet 103 is disposed at the tail 129. Such a configuration is conducive to reducing the distance between the dust outlet 103 and the dust collecting chamber 201, reducing the length of the movement path of garbage objects during dust collection, and reducing the risk of blockage. Correspondingly, in this embodiment, the dust collecting port 301 is disposed on the base station body 310. In some embodiments, the dust outlet 103 can also be disposed at the bottom 122. Correspondingly, in this embodiment, the dust collecting port 301 is disposed on the base 30.

[0086] In some other embodiments, the device main body 100 includes a covering member (not shown in the figure), and the covering member covers the handheld vacuuming device 200.

[0087] Optionally, as Figure 8 shown, the tail portion 129 of the device main body 100 can be used to dock with the base station 300.

[0088] Optionally, as Figure 9 shown, the outer shape of the handheld vacuuming device 200 matches the contour of the peripheral side 123 of the device main body 100. For example, the peripheral side contour of the tail portion 129 is arc-shaped, and correspondingly, the outer contour of the peripheral side of the handheld vacuuming device 200 close to the tail portion 129 is in a matching arc shape to correspond to and match the peripheral side contour of the tail portion 129.

[0089] Furthermore, the handle 241 is arc-shaped to match the peripheral side contour of the tail portion 129. With such a setting, on the one hand, the shape of the handle 241 can match the outer contour of the self-propelled cleaning device 1, which is beneficial to making full use of the space on the device main body 100. Also, when the self-propelled cleaning device 1 performs a rotating action, it can avoid rubbing and colliding with the items in the working environment.

[0090] Optionally, as Figure 9 shown, on a reference plane perpendicular to the height direction D4 of the self-propelled cleaning device 1, the projection of the handheld vacuuming device 200 falls within the projection of the device main body 100. Specifically, the projection of the handheld vacuuming device 200 on the working surface falls within the projection of the device main body 100 on the working surface.

[0091] Perpendicular to the height direction D4 of the self-propelled cleaning device 1, the handheld vacuuming device 200 is set to be retracted relative to the device main body 100. In this way, it can avoid the handheld vacuuming device 200 from rubbing and colliding with the items in the working environment when the self-propelled cleaning device 1 performs actions such as rotating during the cleaning process, and at the same time, it is convenient for the device main body 100 to dock with the base station 300.

[0092] Optionally, as Figure 6 shown, the self-propelled cleaning device 1 further includes an accessory 400a for the handheld vacuuming device 200.

[0097] In some embodiments, as Figure 8 and Figure 14 shown, the suction tube 400 is detachably provided on the device main body 100. The suction tube 400 can be used as a suction nozzle. Specifically, the caliber of the end of the suction tube 400 away from the air inlet 202 can be smaller than the caliber of the air inlet 202, so as to facilitate cleaning of narrow gaps and also help to enhance the suction force.

[0098] By detachably providing the suction tube 400 on the device main body 100, the original space of the device main body 100 is fully utilized, the space occupied by the overall cleaning system is reduced, the device main body 100 can accommodate the suction tube 400, and it is also convenient to take the suction tube 400 as needed.

[0099] Optionally, as Figure 6 shown, the device main body 100 is provided with a receiving groove 108, and the suction tube 400 is detachably received in the receiving groove 108.

[0100] Furthermore, the suction tube 400 can be directly placed in the receiving groove 108, or the suction tube 400 is connected to the inner wall of the receiving groove 108 by a tight fit, a buckle, and / or a magnetic attraction.

[0101] Optionally, the receiving groove 108 is recessed from the top 121 towards the bottom 122.

[0102] Optionally, as Figures 15 to 17 shown, the accessory 400a may further include a floor brush assembly 403 and an extension tube 404. One end of the extension tube 404 is used to be detachably connected to the handheld vacuum device 200 so that the extension tube 404 is communicated with the air inlet 202, and the other end of the suction tube is detachably connected to the floor brush assembly 403.

[0103] Specifically, the extension tube 404 has a first pair of interfaces 4001, a second pair of interfaces 4002, and an extension channel 4005. The extension channel 4005 extends along the extension direction of the extension tube 404, and both ends of the extension channel 4005 communicate with the first pair of interfaces 4001 and the second pair of interfaces 4002 respectively. The first pair of interfaces 4001 is used to communicate with the air inlet 202. The second pair of interfaces 4002 is used for garbage objects to enter the extension channel 4005.

[0104] The floor brush assembly 403 is arranged at the second pair of interfaces 4002. The floor brush assembly 403 can be used to clean the working surface. The dust and garbage swept by the floor brush assembly 403 can be sucked into the extension channel 4005 through the second pair of interfaces 4002 under the suction of the hand-held vacuum device 200, and then sequentially pass through the extension channel 4005 and the first pair of interfaces 4001, and then be sucked into the dust collection chamber 201 of the hand-held vacuum device 200 through the air inlet 202.

[0107] Specifically, as Figures 15 to 17 shown, the hand-held vacuum device 200 is provided with a first electrical connection contact 2021 electrically connected to the power supply assembly 221. Both ends of the extension tube 404 are respectively provided with a second electrical connection contact 4003 and a third electrical connection contact. In a state where the extension tube 404 is assembled and connected to the hand-held vacuum device 200, the first electrical connection contact 2021 and the second electrical connection contact 4003 are electrically connected. The floor brush assembly 403 is provided with a fourth electrical connection contact. In a state where the extension tube 404 is assembled and connected to the floor brush assembly 403, the third electrical connection contact and the fourth electrical connection contact are electrically connected. A wire can be arranged in the extension tube 404 and connected between the second electrical connection contact 4003 and the third electrical connection contact. In this way, in a state where the extension tube 404 is respectively assembled and connected to the hand-held vacuum device 200 and the floor brush assembly 403, the power supply assembly 221 can supply power to the floor brush assembly 403. By extending the extension tube 404, the suction range of the hand-held vacuum device 200 can be extended to a farther distance. Through the floor brush assembly 403, the dust and garbage on the working surface can be swept out, so that the application scenarios of the hand-held vacuum device 200 can be enriched and the cleaning effect can be improved.

[0108] Optionally, the first electrical connection contact 2021 and the second electrical connection contact 4003 are electrically connected by plugging or elastically abutting. Further, the first electrical connection contact 2021 and the second electrical connection contact 4003 are respectively one of the male socket and the female socket of the connection PIN.

[0120] In some embodiments, as Figure 4 shown, when the accommodation part 242 is detached from the device main body 240, the separation space 232 is exposed to the outside, so that the garbage objects in the separation space 232 can be dumped to the outside.

[0121] Optionally, the power supply component 221 is arranged adjacent to the accommodation part 242.

[0122] Optionally, as Figure 9 、 Figures 11 to 13 shown, the handheld vacuum cleaner 200 includes a control button group 2411, and the handle 241 and the air inlet 202 are respectively arranged on opposite sides of the device main body 240. The handle 241 has a first end and a second end, the power supply component 221 is adjacent to the first end of the handle 241, and the second end of the handle 241 is connected to the device main body 240. The control button group 2411 is arranged on the handle 241 and close to the second end of the handle 241.

[0123] Specifically, as Figure 9 、 Figures 11 to 13As shown, the handheld vacuum device 200 has a first direction D1, a second direction D2, and a third direction D3 that are perpendicular to each other. The handle 241 and the air inlet 202 are respectively arranged on both sides of the handheld vacuum device 200 along the first direction D1. In this way, it is convenient for the user to hold the handheld vacuum device 200 for cleaning work. The fan 209 and the power supply assembly 221 are respectively arranged on both sides of the handheld vacuum device 200 along the second direction D2. Both the fan 209 and the power supply assembly 221 have a relatively large weight. In this way, it is beneficial to the overall weight balance distribution of the handheld vacuum device 200, and it is convenient to maintain the balance of the handheld vacuum device 200 when the user holds it, and the setting of the handheld vacuum device 200 is more ergonomic.

[0124] Optionally, the handheld vacuum device 200 is provided with an air outlet 207 communicating with the outside. The fan 209 is communicated with the air outlet 207. Specifically, the air inlet 2091 of the fan 209 is communicated with the outside through the air outlet 207. The air outlet 207 faces the outside along the third direction D3. In this way, when the user holds the handheld vacuum device 200 for cleaning work, the air outlet 207 does not face the user and the area to be cleaned, and it can reduce the influence of the airflow discharged from the air outlet 207 on the cleaning work.

[0125] Optionally, when the handheld vacuum device 200 is assembled and connected to the device main body 100, the air outlet 207 is arranged to face upward, and the device main body 100 is arranged to avoid the air outlet 207.

[0126] When the handheld vacuum device 200 is assembled and connected to the device main body 100, the device main body 100 can avoid the air outlet 207 so that the airflow can be smoothly discharged from the air outlet 207. For example, when the handheld vacuum device 200 is assembled and connected to the device main body 100, the air outlet 207 can face upward.

[0127] Furthermore, the fan 209 has an air outlet 2092 communicating with the air inlet 2091. The airflow enters the fan 209 from the air inlet 2091 and flows out of the fan 209 from the air outlet 2092. Furthermore, the air outlet 2092 is communicated with the air outlet 207.

[0128] Optionally, the power supply assembly 221 is located at a corner of the handheld vacuum device 200 close to the handle 241. When the user holds the handheld vacuum device 200 for cleaning work, the power supply assembly 221 can be at the lower part, and the fan 209 is at the upper front position. Under the weight of the fan 209 and the power supply assembly 221, the air inlet 202 can face a position slightly lower in the front, so as to facilitate the user's cleaning activities.

[0129] Optionally, when the handheld vacuum device 200 is assembled to the device main body 100, the third direction D3 is parallel to the height direction D4 of the self-propelled cleaning device 1.

[0130] Optionally, as Figure 9 shown, in the second direction D2, a control button group 2411 is provided at the second end of the handle 241. The control button group 2411 is used to control the on / off and gear switching functions of the handheld vacuuming device 200. With such a setting, it is convenient for the user to press the control button group 2411 with the thumb while holding the handle 241 with one hand, and at the same time reduce the risk of accidental touch and accidental pressing of the control button group 2411. When the user removes the handheld vacuuming device 200 from the device main body 100, the user can press the unlocking mechanism 109 with one hand and then hold the handle 241, and then press the control button group 2411 to start the handheld vacuuming device 200.

[0131] Optionally, as Figure 9 shown, an indicator light 243 is provided on the handheld vacuuming device 200.

Further, the indicator light 243 is provided on the device main body 240. In the state where the handheld vacuuming device 200 is assembled to the device main body 100, the indicator light 243 is located above the device main body 240 and is exposed to the outside.

[0132] Optionally, as Figure 4 and Figure 6 as well as Figure 12 shown, the handheld vacuuming device 200 includes a blower 209 and a filter assembly 230. The filter assembly 230 is provided on the side of the blower 209 close to the dust collection chamber 201. The filter assembly 230 is used to intercept the garbage objects entering the dust collection chamber 201 through the air inlet 202 and make the garbage objects enter the dust collection chamber 201. By providing the filter assembly 230, the air flow and the garbage objects can be separated from each other, and the dust collection chamber 201 can accommodate the garbage objects.

[0133] For example, the filter assembly 230 includes a centrifugal separation mechanism 231. Since the density of air and garbage objects is different, the centrifugal separation mechanism 231 can separate the air flow and the garbage objects by the principle of centrifugal separation.

[0134] The centrifugal separation mechanism 231 is connected to the device main body 240 and is located in the dust collection chamber 201. In this way, it is beneficial to the uniform distribution of the overall weight of the handheld vacuuming device 200.

[0135] Optionally, the centrifugal separation mechanism 231 is located between the blower 209 and the accommodating portion 242, and the air inlet 202 is located between the blower 209 and the accommodating portion 242. In this way, it is beneficial to the air inlet 202 to be centered, and it is convenient for the handheld vacuuming device 200 to be held and used.

[0136] Optionally, as Figures 10 to 12As shown in the figure, the centrifugal separation mechanism 231 has a separation space 232 inside. The separation space 232 is respectively communicated with the air inlet 2091 and the dust collection chamber 201. The air flow formed by the fan 209 sequentially flows through the dust suction port 101, the air inlet 202, the dust collection chamber 201, the separation space 232 and the air inlet 2091. The dust collection chamber 201 is used to accommodate large particle garbage objects intercepted outside the separation space 232 by the centrifugal separation mechanism 231. The centrifugal separation mechanism 231 is used to perform centrifugal separation on the air flow and garbage objects in the separation space 232 so that small particle garbage objects remain in the separation space 232.

[0137] For example, the centrifugal separation mechanism 231 includes a cyclone separator, and the cyclone separator includes a wind cone tube. With such a setting, it is beneficial to achieve multi-stage separation of garbage objects and improve the separation efficiency of separating garbage objects from the air flow.

[0138] Optionally, as Figures 10 to 12 shown, the filter assembly 230 includes an interception net 233, and the interception net 233 is arranged at the entrance of the separation space 232. The interception net 233 can intercept large-sized garbage objects from entering the separation space 232, which is beneficial to improving the separation efficiency of the air flow and garbage objects. Specifically, the interception net 233 is a metal net.

[0139] In some embodiments, optionally, as Figures 10 to 12 shown, the centrifugal separation mechanism 231 also has an air outlet 234 communicated with the separation space 232, and the separation space 232 is communicated with the air discharge port 207 through the air outlet 234. The purified air flow in the separation space 232 can flow towards the air inlet 2091 through the air outlet 234 and is finally discharged to the outside through the air discharge port 207.

[0140] Optionally, as Figures 10 to 12 shown, a filter element 250 can be arranged between the fan 209 and the filter assembly 230. The filter element 250 has the function of purifying the air flow. Further, the filter element 250 is arranged at intervals between the centrifugal separation mechanism 231 and the fan 209. The path of the purified air flow in the separation space 232 flowing towards the air inlet 2091 passes through the filter element 250, and the filter element 250 can purify the air flow again. Specifically, the filter element 250 is a HEPA (High Efficiency Particulate Air Filter). In some embodiments, multiple filter elements 250 can be arranged, and the multiple filter elements 250 are stacked between the fan 209 and the filter assembly 230.

[0141] Optionally, the handheld vacuum device 200 is provided with a communication port 2013, and the dust collection chamber 201 communicates with the separation space 232 through the communication port 2013. During the dust collection process of the base station 300, the garbage objects in the separation space 232 enter the dust collection chamber 201 through the communication port 2013, then leave the dust collection chamber 201 through the dust removal port 203 and enter the base station 300 through the dust collection port 301.

[0142] Optionally, as Figures 10 to 12 shown, the handheld vacuum device 200 includes a partition member 2014, and the partition member 2014 is movably arranged at the communication port 2013 to open or close the communication port 2013. The base station 300 includes a dust collection fan 320 communicated with the dust collection port 301, and the partition member 2014 is arranged to move from the position closing the communication port 2013 to the position opening the communication port 2013 under the attraction of the dust collection fan 320. In some embodiments, the partition member 2014 is arranged to move from the position opening the communication port 2013 to the position closing the communication port 2013 under the attraction of the fan 209.

[0143] When the self - propelled cleaning device 1 is performing a cleaning operation or the handheld vacuum device 200 is held for cleaning after being removed from the device main body 100, the partition member 2014 can be in the position closing the communication port 2013, which is used to prevent the airflow and garbage objects in the dust collection chamber 201 from entering the separation space 232 through the communication port 2013 under the suction of the fan 209. When the self - propelled cleaning device 1 needs to collect dust, under the suction of the dust collection fan 320, the partition member 2014 can be in the position opening the communication port 2013, and the airflow formed under the action of the dust collection fan 320 can carry the garbage objects into the dust collection chamber 201 through the communication port 2013, then leave the dust collection chamber 201 through the dust removal port 203 and enter the base station 300 through the dust collection port 301, thereby realizing the dust collection function.

[0144] Optionally, the handheld vacuum device 200 is provided with an elastic reset member, and the partition member 2014 is rotatably arranged at the communication port 2013. The elastic reset member is used to limit the partition member 2014 to the position closing the communication port 2013, and the elastic reset member is in an elastically compressed state when the partition member 2014 is in the position opening the communication port 2013.

[0145] When the self - propelled cleaning device 1 is performing cleaning work or the handheld dust - suction device 200 is held for cleaning work after being detached from the device main body 100, the elastic reset member can press the partition member 2014 to the position where the communication port 2013 is covered. When the self - propelled cleaning device 1 needs to collect dust, under the suction force of the dust - collecting fan 320, the partition member 2014 rotates to the position where the communication port 2013 is opened, and at the same time, the elastic reset member is in an elastically compressed state. When the dust collection of the self - propelled cleaning device 1 is completed, the dust - collecting fan 320 stops working, and the elastic reset member elastically returns, causing the partition member 2014 to rotate to the position where the communication port 2013 is covered. Further, the partition member 2014 is arranged to be accelerated by the fan 209 to move to the position where the communication port 2013 is covered. For example, the elastic reset member is a torsion spring. In some embodiments, the elastic reset member can be directly omitted, and the partition member 2014 is directly made of an elastic material. For example, the partition member 2014 can be made of rubber material.

[0146] In other embodiments, such as Figure 4 shown, different from the embodiment Figure 12 shown, in the embodiment Figure 4 shown, the partition member 2014 is omitted, and the communication port 2013 extends to abut against the inner wall of the accommodating portion 242. In this embodiment, the garbage in the separation space 232 cannot be sucked away by the base station, and the user can pour out the garbage in the separation space 232 by detaching the accommodating portion 242.

[0147] Optionally, as Figure 10 shown, the device main body 100 includes a body 130, a rotary brush 1011, and a comb 1012. The rotary brush 1011 is rotatably connected to the body 130 and is arranged at the dust - suction port 101. The comb 1012 is connected to the body 130 and is used to clean the hair wound around the rotary brush 1011.

[0148] Specifically, the rotary brush 1011 and the comb 1012 are arranged at the dust - suction port 101, and when the rotary brush 1011 rotates, it sweeps across the comb 1012. The rotary brush 1011 is used to sweep the working surface to sweep out garbage objects so that the garbage objects can be sucked into the dust - suction port 101. Hairs and silk threads in the garbage objects are easily wound around the rotary brush 1011. When the rotary brush 1011 rotates and sweeps across the comb 1012, the comb 1012 can scrape off the hairs and silk threads wound on the rotary brush 1011, and then they are sucked into the dust - collection cavity 201 by the fan 209. In other embodiments, the comb 1011 can also be omitted, and a cutting structure can also be used to cut the hair wound around the rotary brush 1011, or by controlling the forward and reverse rotation of the rotary brush 1011 to loosen the hair wound around the rotary brush 1011 so that the hair can be sucked into the dust - collection cavity 201.

[0149] Optionally, the rotary brush 1011 can be a rubber - and - hair integrated rotary brush 1011 or a rubber rotary brush.

[0150] Optionally, as Figure 10 and Figure 12 shown, the handheld vacuum device 200 includes a plugging member 2023 for plugging the air inlet 202. The plugging member 2023 is movably disposed at the air inlet 202 so as to be able to switch between a plugging position and a communicating position relative to the air inlet 202. The plugging member 2023 is configured to cover the air inlet 202 in the plugging position and is also configured to be attracted by the fan 209 or the dust collection fan 320 to move from the plugging position to the communicating position to open the air inlet 202. Further, the plugging member 2023 plugs the air inlet 202 inside the handheld vacuum device 200.

[0151] When the self - propelled cleaning device 1 is performing a cleaning operation or the handheld vacuum device 200 is held for cleaning, the plugging member 2023 can be in the communicating position to allow the garbage objects to enter the dust collection chamber 201 through the air inlet 202. When the handheld vacuum device 200 is detached from the device main body 100, the plugging member 2023 can cover the air inlet 202 to prevent the garbage objects in the dust collection chamber 201 from sliding out through the air inlet 202.

[0152] Optionally, the handheld vacuum device 200 includes an elastic pressing member for keeping the plugging member 2023 in the plugging position through elastic action.

[0153] In summary, after the handheld vacuum device 200 is detached from the device main body 100 and the handheld vacuum device 200 is connected to the accessory 400a for cleaning, both the dust removal port 203 and the communication port 2013 are closed. When the fan 209 is started, an air flow can be formed that sequentially flows into the dust collection chamber 201 through the accessory 400a and the air inlet 202. The air flow can carry garbage objects and cause the air inlet 202 to conduct. Some of the garbage objects carried by the air flow can be received in the dust collection chamber 201. The air flow and some of the garbage objects it carries can pass through the intercepting net 233 into the separation space 232 and perform centrifugal separation. The garbage objects separated by centrifugation can be retained in the separation space 232. The air flow purified by centrifugal separation can flow through the air outlet 234, pass through the filter element 250, flow towards the air inlet 2091, and finally be discharged to the outside through the air outlet 207. In this way, multi - stage separation of the garbage objects can be achieved, improving the separation effect.

[0154] After the handheld vacuuming device 200 is assembled to the device main body 100 and when the self - propelled cleaning device 1 is cleaning, the dust removal port 203 and the communication port 2013 are both closed. The airflow formed by the blower 209 can enter the interior of the device main body 100 from the dust suction port 101, then flow out from the dust outlet 102, and in turn drive the air inlet 202 to open and flow into the dust collection chamber 201 through the air inlet 202. The airflow can carry garbage objects. Then the airflow carrying the garbage objects enters the separation space 232 through the intercepting net 233, and centrifugal separation of the airflow and the garbage objects is carried out in the separation space 232. The intercepting net 233 can intercept large - sized garbage objects from entering the separation space 232, so that the large - sized garbage objects are stored in the dust collection chamber 201. The garbage objects centrifugally separated in the separation space 232 can remain in the separation space 232, and the airflow purified in the separation space 232 can flow through the air outlet 234, pass through the filter element 250, and flow towards the air inlet 2091 and finally be discharged to the outside through the air exhaust port 207. In this way, multi - stage separation of the garbage objects can be achieved, improving the separation effect.

[0155] When the self - propelled cleaning device 1 is docked with the base station 300 for dust collection, under the action of the dust collection blower 320, the shielding member 210 rotates to the open position, the partition member 2014 rotates to the position where the communication port 2013 is opened, the blocking member 2023 moves to the communicating position, the air inlet 202, the dust removal port 203 and the communication port 2013 are all opened. The formed airflow can flow into the dust collection chamber 201 from the outside through the air inlet 202, and the formed airflow can also flow into the separation space 232 from the outside through the air exhaust port 207. The airflow can carry the garbage objects in the separation space 232 and the dust collection chamber 201 to leave the handheld vacuuming device 200 through the dust removal port 203 and enter the device main body 100 through the dust inlet 104, and then enter the base station 300 through the dust discharge port 103 and the dust collection port 301.

[0156] The process of dust collection by the base station 300 is further described in detail below.

[0157] Regarding the process of base station dust collection, the traditional dust collection method for cleaning devices is as follows: The cleaning device is docked with the base station, and the dust collection blower is continuously turned on for a period of time to suck the garbage objects in the cleaning device into the base station. However, since the working process of the dust collection blower is relatively single, the suction of the garbage objects in the cleaning device is not sufficient, resulting in easy residue of garbage objects in the cleaning device.

[0158] In addition, for the cleaning system 10 provided in the present application, the internal space structure and the airflow flow path of the handheld vacuuming device 200 are relatively complex, and the working effect of the traditional dust collection method is poor. Therefore, the present application provides a more effective dust collection strategy below to meet the dust collection requirements of the cleaning system 10 and improve the cleaning effect of the self - propelled cleaning device 1.

[0159] The cleaning system 10 described in the embodiments of the present application includes a self-propelled cleaning device 1 and a base station 300 for docking with the self-propelled cleaning device 1. The self-propelled cleaning device 1 has a dust collection chamber 201. The self-propelled cleaning device 1 includes a fan 209, and the fan 209 is communicated with the dust collection chamber 201. The fan 209 is used to form an air flow flowing into the dust collection chamber 201, and the dust collection chamber 201 is used to accommodate the garbage objects carried by the air flow. The base station 300 includes a dust collection fan 320, and the dust collection fan 320 is used to suck the garbage objects in the dust collection chamber 201 into the base station 300. The cleaning system 10 has a dust collection mode. In the dust collection mode: the self-propelled cleaning device 1 and the base station 300 are docked. There is an alternating start-up stage for the dust collection fan 320 and the fan 209. In the alternating start-up stage, the dust collection fan 320 and the fan 209 are alternately started.

[0160] Specifically, one working process of the fan 209 includes start-up, continuous operation after start-up, and shutdown after continuous operation. Similarly, one working process of the dust collection fan 320 includes start-up, continuous operation after start-up, and shutdown after continuous operation. The alternating start of the dust collection fan 320 and the fan 209 means that the dust collection fan 320 and the fan 209 start successively and do not start simultaneously.

[0161] In some embodiments, the self-propelled cleaning device 1 and the base station 300 cooperate with each other to perform a dust collection method. The dust collection method includes: S100: controlling the self-propelled cleaning device and the base station to dock; S200: controlling the dust collection fan and the fan to work in sequence; S300: controlling the dust collection fan to work again.

[0162] When the dust collection fan 320 is working, it will suck the garbage objects in the dust collection chamber 201 into the base station 300 along the suction path. If there are too many garbage objects in the dust collection chamber 201, it is easy to cause blockage of the garbage objects on the suction path. For example, the garbage objects in the dust collection chamber 201 can be sucked into the dust bag of the base station 300 through the dust collection channel 1031. If there are too many garbage objects in the dust collection chamber 201, it is easy to cause blockage of the garbage objects in the dust collection channel 1031 or at the entrance of the dust collection channel 1031. The dust collection fan 320 can be controlled to start at least twice. When the dust collection fan 320 is working after starting, the working power and working duration of the dust collection fan 320 can be controlled to first suck some of the garbage objects in the dust collection chamber 201 into the base station 300, which is not easy to cause blockage of the garbage objects. When the dust collection fan 320 is working after subsequent start-up, the remaining garbage objects in the dust collection chamber 201 are partially sucked into the base station 300.

[0163] During the alternating startup phase, when controlling the dust collection fan 320 to stop working, the fan 209 can be controlled to start. The airflow path formed by the operation of the fan 209 is different from the airflow path formed by the operation of the dust collection fan 320. Therefore, the operation of the fan 209 can reduce the risk of garbage blockage and improve the dust collection effect.

[0164] Specifically, on the one hand, if the garbage blocks in the suction path when the dust collection fan 320 is working, the blocked garbage accumulates more tightly at one end close to the dust collection fan 320 and more loosely at the end far from the dust collection fan 320. The dust collection fan 320 directly acts on the more tightly packed garbage, but the more tightly packed garbage is stuck in the direction towards the dust collection fan 320 and is not easily loosened. The fan 209 can directly act on the more loosely packed garbage far from the dust collection fan 320. Under the suction of the fan 209, the more loosely packed garbage can move towards the fan 209, and then the fan 209 can directly act on the more tightly packed garbage. Since the acting force generated by the operation of the fan 209 and the acting force generated by the operation of the dust collection fan 320 are in opposite directions, the more tightly packed garbage can also be loosened under the suction of the fan 209. On the other hand, if the garbage accumulates in the suction path when the dust collection fan 320 is working, the suction of the fan 209 can disperse the accumulated garbage. For example, the suction of the fan 209 can cause the accumulated garbage to move around the external centrifugal structure, thereby dispersing the accumulated garbage. Therefore, the suction of the fan 209 can dredge the suction path of the garbage and reduce the risk of garbage blockage.

[0165] In addition, the dust collection fan 320 and the fan 209 are alternately started, which can reduce the generated noise.

[0166] In some embodiments, in the dust collection mode: during the alternating startup phase, the fan 209 and the dust collection fan 320 work alternately to reduce the generated noise and also avoid partial airflow of the dust collection fan 320 and the fan 209 from counteracting each other.

[0167] In other embodiments, during the alternating startup phase, the working times of the dust collection fan 320 and the fan 209 partially overlap. That is to say, during the alternating startup phase, there are situations where the dust collection fan 320 and the fan 209 do not work simultaneously, and there are also situations where they work simultaneously. The simultaneous operation of the dust collection fan 320 and the fan can generate a more complex airflow path, which can further reduce the dust collection dead angle and also enhance the suction force on the rotary brush 1011 to enhance the cleaning effect on the rotary brush 1011.

[0168] In some embodiments, some parts within the dust collection chamber 201 and other parts of the self - propelled cleaning device 1 that are connected to the dust collection chamber 201 may be outside the flow range of the air flow formed when the dust collection fan 320 operates. When the dust collection fan 320 operates, a dust collection dead - end will be formed, and the garbage objects in the dust collection dead - end are not easily sucked into the base station 300. The operation of the fan 209 can carry the garbage objects in the dust collection dead - end away from the dust collection dead - end, so that these garbage objects can be sucked into the base station 300, thereby improving the dust collection effect. Generally speaking, the more complex the structure of the dust collection chamber 201 is, or the more complex the structure of the self - propelled cleaning device 1 connected to the dust collection chamber 201 is, the easier it is to form a dust collection dead - end, and the more obvious the improvement of the dust collection effect by the operation of the fan 209 is. Therefore, the above - mentioned dust collection method has good applicability and compatibility for the cleaning system 10 with a complex internal space structure.

[0169] In some embodiments, during the dust collection process, step S200 may be executed once. In other embodiments, during the dust collection process, step S200 may be repeatedly executed, and step S200 may be executed at least twice. For example, step S200 may be executed twice or three times, and step S300 is executed after executing step S200 twice or three times.

[0170] In some embodiments, during the dust collection process, the dust collection fan 320 may be continuously started at least twice, and then the dust collection fan 320 stops working, and the fan 209 starts.

[0171] In some embodiments, during the dust collection process, the fan 209 may be continuously started at least twice, and then the fan 209 stops working, and the dust collection fan 320 starts.

[0172] Optionally, in the dust collection mode: the first start of the dust collection fan 320 is before the first start of the fan 209. Further, the first operation of the dust collection fan 320 is before the first operation of the fan 209, that is, the first stop of the dust collection fan 320 is before the first start of the fan 209.

[0173] With such a setting, the garbage objects in the dust collection chamber 201 can be sucked into the base station 300 as early as possible, which is beneficial to shortening the dust collection time.

[0174] In other embodiments, in the dust collection mode, the fan 209 starts first.

[0175] Optionally, in the dust collection mode: the last start of the dust collection fan 320 is after the last start of the fan 209. Further, the last operation of the dust collection fan 320 is after the last operation of the fan 209, that is, the last start of the dust collection fan 320 is after the last stop of the fan 209.

[0176] The fan 209 can suck the garbage objects into the dust collection chamber 201 and blow the garbage objects to move. With such a setting, it is beneficial to improve the suction effect of the dust collection fan 320 on the garbage objects in the dust collection chamber 201, reduce the residue of the garbage objects in the dust collection chamber 201, and improve the dust collection effect.

[0177] For example, during the dust collection process, the dust collection fan 320 can work twice, the fan 209 can work once, and the fan 209 works between the two operations of the dust collection fan 320. Another example is that during the dust collection process, the dust collection fan 320 can work 3 times, and the fan 209 can work 2 times. For example, the dust collection fan 320 and the fan 209 work alternately according to the sequence in Table 1. Another example is that the dust collection fan 320 and the fan 209 work alternately according to Tables 2 and 3.

[0178] Table 1 Example of the working timing sequence of the dust collection fan, the fan, and the roller brush motor in the dust collection mode

[0179]

[0180] With such a setting, the amount of garbage objects sucked by the dust collection fan 320 each time will not be too large, and it is not easy to cause blockage of the garbage objects. After each suction by the dust collection fan 320, the suction effect of the fan 209 can dredge the suction path of the garbage objects and reduce the risk of blockage of the garbage objects. Each time the fan 209 works, it can also blow the garbage objects in the dust collection dead corners away from the dust collection dead corners, so that these garbage objects can be sucked into the base station 300 by the dust collection fan 320 later, thereby improving the dust collection effect.

[0181] Optionally, there is a power-lifting process during the operation of the dust collection fan 320. During the power-lifting process, the working power of the dust collection fan 320 in the previous working process is less than the working power of the subsequent working process.

[0182] Furthermore, in the dust collection mode: the dust collection fan 320 starts at least twice, and the working power of the first start of the dust collection fan 320 is less than the working power of the second start.

[0183] With such a setting, during the dust collection process, the working power of the dust collection fan 320 before the power-lifting process is relatively small, so the amount of garbage objects sucked by the dust collection fan 320 will not be too large, and it is not easy to cause blockage of the garbage objects. After the power-lifting process, the working power of the dust collection fan 320 is relatively large, which is beneficial to sucking the garbage objects into the base station 300 sufficiently and improving the dust collection effect.

[0184] In some embodiments, as shown in Table 1, the power-lifting process occurs during the first and second operations of the dust collection fan 320, and the ratio of the working power of the dust collection fan 320 to the rated power increases from 65% to 100%.

[0185] In some embodiments, the power boost process may occur during the adjacent 3 or 4 operations of the dust collection fan 320. For example, the ratio of the operating power of the dust collection fan 320 to the rated power may increase from 40% during the first operation to 65% during the second operation, and then to 100% during the third operation. Among them, the number of operations of the dust collection fan 320 included in the power boost process can be set according to the capacity of the dust collection chamber 201 and the cross-section of the suction path. The larger the capacity of the dust collection chamber 201 and the smaller the cross-sectional size of the suction path, the more operations of the dust collection fan 320 included in the power boost process, and the smaller the operating power of the dust collection fan 320 during the early operations.

[0186] Of course, in other embodiments, the operating power of the dust collection fan 320 at the first start-up may also be equal to the operating power at the second start-up. In this embodiment, the operating power of the dust collection fan 320 at each start-up can be kept consistent.

[0187] In some embodiments, the ratio of the operating power of the dust collection fan 320 to the rated power may be 30%, 40%, 50% or 70%.

[0188] Optionally, during the power boost process, the ratio range of the operating power of the dust collection fan 320 in the previous operation process to the operating power in the next operation process is 50% - 80%.

[0189] For example, the ratio range of the operating power of the dust collection fan 320 in the previous operation process to the operating power in the next operation process is 55%, 65% or 75%.

[0190] With such a setting, it can be ensured that the difference between the operating power of the dust collection fan 320 in the previous operation process and the operating power in the next operation process is not too small, so that enough garbage can be sucked during the next operation. At the same time, it can be ensured that the difference between the operating power of the dust collection fan 320 in the previous operation process and the operating power in the next operation process is not too large, so that the amount of garbage sucked during the next operation will not be excessive and cause blockage.

[0191] Optionally, the operating power of the dust collection fan 320 after the power boost process is the same as the operating power in the last operation during the power boost process.

[0192] Furthermore, in the dust collection mode: the dust collection fan 320 is started at least three times, and the operating power of the dust collection fan 320 at each start-up after the second start-up is the same as the operating power at the second start-up.

[0193] The operating power of the dust collection fan 320 during the second startup can be the maximum operating power of the dust collection fan 320 or other set power. For example, if the operating power of the dust collection fan 320 during the second startup is 100% of the rated power, the operating power of the dust collection fan 320 after the second startup is set to 100% of the rated power. In this way, it is beneficial to fully suck the garbage into the base station 300 and improve the dust collection effect. For example, the operating power of the dust collection fan 320 will continue to work 1 time, 2 times or 3 times after reaching the maximum operating power.

[0194] Optionally, during the dust collection process, the operating power of the fan 209 can be 80% of the rated power, which is beneficial to improve the service life of the fan 209. When the self-propelled cleaning device 1 cleans the working surface, the operating power of the fan 209 can also be 80% of the rated power. It is worth mentioning that the rated power of the fan 209 can be less than or equal to the rated power of the dust collection fan 320.

[0195] Optionally, during the power increase process, the working duration of the dust collection fan 320 in the subsequent working process is greater than that in the previous working process. For example, as shown in Table 1, during the power increase process, the working duration of the dust collection fan 320 in the subsequent working process is 8s, and the working duration of the previous working process is 5s. That is to say, during the power increase process, as the operating power of the dust collection fan 320 increases, the working duration of the dust collection fan 320 each time also increases.

[0196] With such a setting, during the dust collection process, the working duration of the dust collection fan 320 is relatively small in the initial stage of the power increase process, so the amount of garbage sucked by the dust collection fan 320 will not be too large, and it is not easy to cause blockage of the garbage. In the later stage of the power increase process, the working duration of the dust collection fan 320 is relatively large, which is beneficial to fully suck the garbage into the base station 300 and improve the dust collection effect.

[0197] In some other embodiments, if the number of working times of the dust collection fan 320 is greater than 2 times during the power increase process, the working duration of the dust collection fan 320 can increase successively. For example, the working duration of the dust collection fan 320 each time can increase from 5s in the first working to 8s in the second working, and then to 12s in the third working. Among them, the working duration of the dust collection fan 320 in the later stage of the power increase process can be set according to the capacity of the dust collection chamber 201 and the cross-section of the suction path. The larger the capacity of the dust collection chamber 201 and the smaller the cross-section size of the suction path, the larger the working duration of the dust collection fan 320 in the later stage of the power increase process.

[0198] In some embodiments, the working duration of the dust collection fan 320 each time can be 3s, 10s or 15s.

[0199] Optionally, the last working duration of the dust collection fan 320 during the power boost process is greater than the single working duration of the dust collection fan 320 after the power boost process. For example, as shown in Table 1, the last working duration of the dust collection fan 320 during the power boost process is 8 s, and the single working duration of the dust collection fan 320 after the power boost process is 5 s. Another example is that the last working duration of the dust collection fan 320 during the power boost process is 12 s, and the single working duration of the dust collection fan 320 after the power boost process is 6 s.

[0200] During the last working duration of the dust collection fan 320 in the power boost process, both the working power and the working duration reach the maximum, and most of the garbage can be sucked into the base station 300. Therefore, a shorter single working duration of the dust collection fan 320 after the power boost process is beneficial to saving the suction time and improving the time efficiency.

[0201] Optionally, after the dust collection fan stops working, controlling the fan to work includes:

[0202] S201: Control the fan to work after a preset interval time since the dust collection fan is controlled to stop.

[0203] After the fan stops working, controlling the dust collection fan to work again includes:

[0204] S301: Control the dust collection fan to work after a preset interval time since the fan is controlled to stop.

[0205] For example, as shown in Table 1, the preset interval time is 1 s. After controlling the dust collection fan 320 to stop for 1 s, control the fan 209 to start. After controlling the fan 209 to stop for 1 s, control the dust collection fan 320 to start. In some other embodiments, the preset interval time can also be set to 0.5 s, 2 s or 3 s. In addition, these two preset interval times can be the same or different.

[0206] After the dust collection fan 320 or the fan 209 stops, the stop of the generated air flow will lag. By setting a preset interval time, the situation where some air flows generated by the dust collection fan 320 and the fan 209 counteract each other can be reduced.

[0207] Optionally, in the dust collection mode: the fan 209 has at least a first working power and a second working power, and the first working power is less than the second working power. For example, as shown in Table 2, the first working power can be 12% of the rated power, and the second working power can be 80% of the rated power.

[0208] In this way, the fan 209 can change the dust collection power to achieve different functional effects.

[0209] Further, in the dust collection mode: during at least one continuous operation of the fan 209, the operating power of the fan 209 is increased from a first operating power to a second operating power.

[0210] Specifically, when the fan 209 operates at the first operating power, it can suck garbage objects into the dust collection chamber 201. When the fan 209 operates at the second operating power, it can make the garbage objects in the dust collection chamber 201 move and rise, so as to be fully sucked into the base station 300.

[0215]

[0216] Table 4 Another example of the working timing sequence of the roller brush motor in the dust collection mode

[0217]

[0218] Optionally, the self - propelled cleaning device 1 further includes a roller brush motor for driving the roller brush 1011 to rotate. In the dust collection mode: the roller brush motor drives the roller brush 1011 to alternate between forward rotation and reverse rotation. Wherein, the forward direction is the rotation direction of the roller brush 1011 when the self - propelled cleaning device 1 cleans the working surface.

[0219] Such a setting is beneficial to improving the cleaning effect of the roller brush 1011.

[0220] Specifically, the forward and reverse rotation alternation of the roller brush 1011 can make the hair wound around the roller brush 1011, or the garbage attached to the roller brush bracket, or the garbage stuck between the roller brush 1011 and the roller brush bracket all be taken away under the suction of the fan 209 and the dust collection fan 320. Here, the roller brush bracket is connected to the fuselage 130 and is used to install the roller brush 1011. It is worth mentioning that in the embodiment with the comb teeth 1012, cooperating with the comb teeth 1012 can improve the cleaning effect of the hair wound around the roller brush 1011.

[0221] As shown in Table 1 and Table 4, when the voltage of the roller brush motor is positive, the roller brush 1011 is controlled to rotate forward. When the voltage of the roller brush motor is negative, the roller brush 1011 is controlled to rotate in reverse.

[0222] Optionally, in the dust collection mode: after the roller brush motor is started for the first time, it drives the roller brush 1011 to rotate forward to avoid large particle waste objects being spit out from the dust suction port 101 at the beginning of the dust collection process. Therefore, after the roller brush motor is started for the first time, it drives the roller brush 1011 to rotate forward first, and then switches to reverse rotation. Of course, in other embodiments, the roller brush motor can also drive the roller brush 1011 to rotate reversely first.

[0223] Optionally, in the dust collection mode: the stop time after the last start of the roller brush 1011 is earlier than the stop time after the last start of the dust collection fan 320.

[0224] The dust collection fan 320 can suck the waste objects on the roller brush 1011 into the dust collection chamber 201 and further suck them into the base station 300. Such a setting is conducive to improving the cleaning effect of the dust collection fan 320 on the roller brush 1011.

[0225] Optionally, in the dust collection mode: the roller brush 1011 is switched from forward rotation to reverse rotation at least twice. That is to say, in the dust collection mode, the roller brush 1011 rotates forward and backward at least two rounds. Such a setting is conducive to improving the cleaning effect of the roller brush 1011.

[0226] Optionally, the cleaning system 10 has a charging mode. In the charging mode, the base station 300 charges the self-propelled cleaning device 1. After the cleaning system 10 ends the dust collection mode, it enters the charging mode. It is worth mentioning that the self-propelled cleaning device 1 does not always enter the dust collection mode after docking with the base station 300. It can also directly enter the charging mode according to the actual situation. For example, when the time for the self-propelled cleaning device 1 to leave the base station 300 does not reach the preset duration, it is defaulted that the self-propelled cleaning device 1 has not performed the cleaning task or the cleaning time is too short, so the waste in the dust collection chamber 201 is too little and there is no need to perform the dust collection operation.

[0227] The self-propelled cleaning device 1 consumes electric energy in the dust collection mode, and then enters the charging mode to supplement the electric energy, which is convenient for subsequent cleaning of the working surface.

[0228] Specifically in this embodiment, the dust discharge port 103 is arranged at the tail 129 of the device main body 100. Therefore, in the dust collection mode, the tail of the self-propelled cleaning device 1 is docked with the base station 300, that is, the tail 129 of the device main body 100 is docked with the base station 300. As Figure 5As shown, the self - propelled cleaning device 1 further includes a charging electrode plate 500. The charging electrode plate 500 is arranged at the bottom 122 of the device main body 100 and near the head 128. Therefore, in the charging mode, the head of the self - propelled cleaning device 1 is docked with the base station 300, that is, the head 128 of the device main body 100 is docked with the base station 300. That is to say, when the self - propelled cleaning device 1 needs to perform dust collection operation, the self - propelled cleaning device 1 first seats on the base station 300 with its tail 129 facing the base station 300. When the dust collection operation is completed, the self - propelled cleaning device 1 needs to leave the base station 300 first, rotate 180°, and then seat on the base station 300 with its head 128 facing the base station 300 so that the base station 300 can charge the self - propelled cleaning device 1. In this embodiment, setting the charging electrode plate 500 at the bottom 122 of the device main body 100 and near the head 128 can reduce the weight of the tail 129 of the device main body 100, reasonably distribute the center of gravity of the self - propelled cleaning device 1, and avoid the phenomenon of the self - propelled cleaning device 1 tipping up during walking.

[0229] In some other embodiments, the charging electrode plate 500 can also be arranged at the tail 129 of the device main body 100. In this way, in the charging mode and the dust collection mode, the docking position of the self - propelled cleaning device 1 with the base station 300 is the same. When changing from the dust collection mode to the charging mode, the self - propelled cleaning device 1 does not need to change its position, so as to improve the overall efficiency.

[0230] Such a setting is beneficial to realizing the multi - stage separation of garbage objects and improving the separation efficiency of separating garbage objects from the air flow.

[0231] In summary, in this embodiment, the hand - held dust - suction device 200 can be detached from the device main body 100 to suck garbage objects. The hand - held dust - suction device 200 and the device main body 100 can cooperate to suck garbage objects. The dust - collection cavity 201 can be used independently by the hand - held dust - suction device 200 and can also be used by the hand - held dust - suction device 200 assembled on the self - propelled cleaning device 1 of the device main body 100. It can save space, improve the space utilization rate of the self - propelled cleaning device 1, and the saved space can be used to set parts that can enhance the cleaning function to improve the cleaning effect.

[0232] The above are only the embodiments of the present application, and do not limit the patent scope of the present application accordingly. All equivalent structural or equivalent process transformations made by using the content of the specification and drawings of the present application, or directly or indirectly applied in other related technical fields, are equally included in the patent protection scope of the present application.
