[0050] like Figure 1 and Figure 2 The present invention provides a cleaning system, which includes a vacuum cleaner 100 and a base station 200. The vacuum cleaner 100 includes a main unit 110, a floor brush 120, and a dust inlet pipe 130. The dust inlet pipe 130 is a rigid pipe that connects the main unit 110 and the floor brush 120. The dust inlet pipe 130 is hollow inside to form a dust inlet air duct 131, which connects the floor brush 120 and the main unit 110.

[0051] The floor brush 120 is equipped with a roller brush 121 and suction ports 122 distributed towards the roller brush 121. The suction ports 122 are connected to the main unit 110 through a dust inlet duct 131. The main unit 110 has a built-in main motor (not shown). The suction ports 122 are connected to the air inlet of the main motor through the dust inlet duct 131 to form a suction airflow within the dust inlet duct 131.

[0052] When the roller brush 121 rotates in the working direction, it can lift up the dust and debris on the surface to be cleaned and sweep the dirt on the surface to be cleaned to the suction port 122. The suction airflow in the dust inlet duct 131 sucks in the dust and debris and dirt, and finally collects them into the dust cup (not shown) of the main unit 110 through the dust inlet duct 131. The dust cup has an openable cup lid, and the dirt in the dust cup can be cleaned by opening the cup lid.

[0053] As described above, the dust cup and roller brush 121 are the areas with the most severe dirt on the vacuum cleaner 100. If these areas are not cleaned promptly, the cleaning effect and efficiency of the vacuum cleaner will be affected. In this embodiment, the base station 200 can interface with the vacuum cleaner 100 and simultaneously clean both the dust cup and roller brush 121, thus cleaning these two areas with the most severe dirt. This improves the cleaning effect and efficiency of the vacuum cleaner 100 and also avoids the need for the user to manually clean these two areas, improving the user experience.

[0054] Specifically, the base station 200 includes a base shell 230, a dust inlet chamber 231 formed in the base shell 230, a second dust collection component 240 disposed in the base shell 230 and communicating with the dust inlet chamber 231, and a base station motor 210 disposed in the base shell 230. The dust inlet chamber 231 has a dust inlet 2311 formed on the top of the base shell 230, and the dust inlet 2311 is used to dock with the dust cup of the vacuum cleaner 100.

[0055] The base station motor 210 can be located on the outside of the base housing 230, or partially inside the base housing 230 (e.g., the air inlet of the base station motor 210 is located inside the base housing 230) and partially outside the base housing 230 (e.g., the air outlet of the base station motor 210 is located outside the base housing 230). The second dust collection component 240 is in fluid communication with the dust inlet 2311, and the base station motor 210 is used to generate a suction airflow through the dust inlet chamber 231 and the second dust collection component 240.

[0056] The second dust collector 240 is a filter structure capable of intercepting dirt while allowing gas to pass through. Preferably, the second dust collector 240 is a filter bag. The base shell 230 has a space for accommodating the second dust collector 240, and the air inlet of the base station motor 210 communicates with the space where the second dust collector 240 is located. The second dust collector 240 is detachably connected to the lower part of the dust inlet chamber 231, for example, by means of a snap-fit ​​mechanism, so that when the second dust collector 240 is full of dirt, it can be easily removed from the aforementioned space.

[0057] The docking direction between the vacuum cleaner 100 and the base station 200 can be in the horizontal direction (e.g., front, back, left, right) or in the vertical direction (e.g., up, down), as long as it can enable the dust cup to be docked with the dust inlet 2311. The dust inlet 2311 is set to face upwards to facilitate docking with the dust cup.

[0058] When the vacuum cleaner 100 is connected to the base station 200, the lid of the dust cup is triggered to open by the base station 200 during the connection process. The dirt in the dust cup enters the dust inlet 231 through the dust inlet 2311 under the action of negative pressure suction airflow, and is finally stored in the second dust collection component 240, thereby transferring the dirt in the dust cup to the base station 200 and realizing the self-cleaning of the dust cup.

[0059] The negative pressure suction airflow from the base station motor 210 flows to the air inlet of the base station motor 210 after being filtered by the second dust collection component 240, and then flows out from the air outlet 211 of the base station motor 210. To achieve cleaning of the dust cup of the base station 200 while simultaneously cleaning the roller brush 121, the shell wall of the base housing 230 is provided with a connection interface 220 that communicates with the air outlet 211 of the base station motor 210. In one embodiment, the connection interface 220 and the air outlet 211 of the base station motor 210 are fluidly connected through an airflow channel. When the base station motor 210 is working, the airflow discharged from the air outlet 211 is finally discharged through the connection interface 220, wherein the connection interface 220 is under positive pressure.

[0060] The dust inlet pipe 130 has a connection port 132 on its wall that mates with the interface 220, and the connection port 132 is connected to the dust inlet air duct 131. To ensure that the vacuum cleaner 100 can perform cleaning tasks normally and that there is sufficient airflow to the suction port 122 when cleaning the roller brush 121, the suction port 122 is connected to either the connection port 132 or the main unit 110. That is, the suction port 122 can be in a state connected to the connection port 132 or connected to the main unit 110.

[0061] The connection port 132 is closable and located on the dust inlet pipe 130. When the vacuum cleaner 100 is working normally, the connection port 132 is closed, and the suction port 122 is connected to the dust cup of the main unit 110. Dirt on the surface to be cleaned can enter the dust inlet duct 131 under the action of the negative pressure suction airflow of the suction port 122, and is finally collected into the dust cup, thereby realizing the cleaning operation of the surface to be cleaned.

[0062] When the vacuum cleaner 100 is connected to the base station 200 (with the vacuum cleaner 100 positioned behind the base station 200), the air outlet of the base station motor 210 connects to the suction port 122. Specifically, the connection port 132 is open and connected to the docking port 220. The airflow from the air outlet of the base station motor 210 passes through the docking port 220 and the connection port 132 and enters the dust inlet duct 131, flowing towards the suction port 122. Finally, it is blown onto the roller brush 121 through the suction port 122, blowing off the hair and dust adhering to the cleaning roller brush 121, thus achieving the cleaning operation of the roller brush 121. Therefore, the base station 200 can not only clean the dust cup but also clean the roller brush 121, achieving a more comprehensive cleaning of the vacuum cleaner and freeing the user's hands.

[0063] After a period of use, the dust inlet pipe 130 accumulates more dust on its inner wall closer to the suction port 122. This accumulated dust reduces the flow cross-section of the dust inlet duct 131, increases wind resistance, and hinders the suction airflow from drawing dirt from the surface to be cleaned into the dust cup, thus affecting the cleaning efficiency of the vacuum cleaner. However, the airflow from the base station motor 210 can clean the areas with severe dust accumulation. When the airflow enters the dust inlet duct 131 through the connection port 132, it blows against the inner wall of the dust inlet pipe 130, dislodging the accumulated dust and thus cleaning the inner wall of the dust inlet pipe 130 in areas with severe dust accumulation. This achieves deep cleaning of the vacuum cleaner 100 by the base station 200.

[0064] To allow the connection port 132 to be opened and closed, and to enable selective connection between the dust inlet 122 and the connection port 132 or the main unit 110, an air duct switching component 140 is also provided on the dust inlet pipe 130. For example... Figure 3 and Figure 4 As shown, the air duct switching component 140 has a sealing part 141 located in the dust inlet air duct 131. The sealing part 141 has a first position that blocks the connection port 132 and a second position that cuts off the dust inlet air duct 131 in the air inlet direction (up and down direction).

[0065] When the sealing part 141 is in the first position, the vacuum cleaner 100 is independent of the base station 200, such as Figure 3 As shown, the connection port 132 is in the closed state. At this time, the suction port 122 is connected to the dust cup, and the vacuum cleaner 100 performs the cleaning task on the surface to be cleaned.

[0066] When the sealing part 141 is in the second position, the vacuum cleaner 100 and the base station 200 are in a docked state, and the vacuum port 122 is connected to the docking port 220, such as Figure 4 As shown, the sealing part 141 is located above the central axis X of the connection port 132. At this time, the airflow from the interface 220 can only flow towards the dust suction port 122 after entering the dust inlet duct 131, which can clean the roller brush 121.

[0067] In one embodiment, such as Figure 5 and Figure 6 As shown, the duct switching component 140 is a hollow cavity shell rotatably connected to the dust inlet pipe 130. The hollow cavity shell includes a communicating end 142 with an opening area and a sealing part 141 excluding the opening area. The sealing part 141 can be understood as the shell wall of the hollow cavity shell. The duct switching component 140 can be installed in the dust inlet duct 131 by means of a support frame (not shown). Specifically, the support frame is fixed in the dust inlet duct 131, and the duct switching component 140 is rotatably mounted on the support frame.

[0068] like Figure 5As shown, when the sealing part 141 rotates to the first position, the sealing part 141 closes the connection port 132. The suction airflow near the dust inlet 122 enters the hollow cavity of the hollow cavity shell through the connecting end 142, then flows out of the hollow cavity through the connecting end 142 and enters the dust inlet duct 131, and then enters the dust cup through the dust inlet duct 131, thus storing dirt in the dust cup. When the sealing part 141 rotates to the second position, as... Figure 6 As shown, the connection port 132 is connected to the suction port 122 through the connecting end 142. The airflow from the interface 220 enters the hollow cavity of the hollow cavity shell after passing through the connecting end 142, and then flows out of the hollow cavity through the connecting end 142, and finally blows onto the roller brush 121 through the suction port 122.

[0069] The air duct switching component 140 can be switched manually or automatically by rotation. When the air duct switching component 140 is switched manually, such as... Figure 2 As shown, the air duct switching component 140 also has a grip portion 143 located outside the dust inlet pipe 130. The grip portion 143 is connected to the sealing portion 141, and the sealing portion 141 can switch between a first position and a second position in response to the operation of the grip portion 143. In use, the user rotates the grip portion 143 by hand to adjust the position of the sealing portion 141.

[0070] When the air duct switching component 140 switches in an automatic mode, the sealing part 141 is also connected to a first driving component (not shown in the figure). The first driving component is used to provide rotation drive to drive the sealing part 141 to rotate autonomously, thereby realizing the adjustment of the position of the sealing part 141.

[0071] Considering that the connection port 132 is located in the circumference of the dust inlet pipe 130, in order to facilitate the smooth docking of the connection port 132 and the docking interface 220, preferably, the docking interface 220 is located on the circumferential side wall of the base shell 230 of the base station 200. Preferably, after the vacuum cleaner 100 docks with the base station 200, a sealed connection is formed between the docking interface 220 and the connection port 132.

[0072] In one embodiment, the connector 132 is inserted into the interface 220, and the outer wall of the connector 132 abuts against the inner wall of the interface 220, thereby achieving a seal. Alternatively, a sealing ring may be provided on the outer wall of the connector 132 and / or the inner wall of the interface 220, thereby achieving a sealed connection between the connector 132 and the interface 220.

[0073] In another embodiment, one of the end edges of the connector 132 and the end edge of the interface 220 is provided with an annular groove (not shown), and the other is provided with an annular rib (not shown). The annular rib is inserted into the annular groove, and a labyrinth seal is achieved through the annular rib and the annular groove.

[0074] In order to ensure that the connection port 132 and the docking interface 220 are well maintained in the docking position, the circumferential side wall of the base station 200 and / or the pipe wall of the dust inlet pipe 130 are provided with a first connection structure 400. The first connection structure 400 is configured to keep the dust inlet pipe 130 in the preset position after docking when the vacuum cleaner 100 docks with the base station 200. As a result, the relative movement between the connection port 132 and the docking interface 220 is not easy to occur, ensuring the reliability and stability of the connection between the connection port 132 and the docking interface 220, thereby maximizing the airflow at the docking interface 220 to the roller brush 121.

[0075] In one embodiment, the first connecting structure 400 is a snap-fit ​​component near the interface 220. The snap-fit ​​component is fixedly mounted on the circumferential sidewall of the base station 200 and has a U-shaped groove that mates with the dust inlet pipe 130. The U-shaped groove guides and fixes the dust inlet pipe 130 when the vacuum cleaner 100 is connected to the base station 200, ensuring a sealed connection between the interface 220 and the connection port 132. In another embodiment, the first connecting structure 400 is a magnetic component disposed on the interface 220 and the connection port 132. Specifically, a pair of magnetic components are respectively disposed at the ends of the interface 220 and the connection port 132, achieving a sealed connection between the connection port 132 and the interface 220 through the magnetic attraction between the magnetic components.

[0076] Furthermore, such as Figures 7 to 9 As shown, the base station 200 has a ground brush support structure 300 at the bottom that cooperates with the ground brush 120. The ground brush support structure 300 is used to support the ground brush 120 from the bottom and to collect dirt blown off by the ground brush 120 under the action of airflow.

[0077] The top of the floor brush support structure 300 is recessed downwards to form a floor brush receiving cavity 310. After the vacuum cleaner 100 is docked with the base station 200, the floor brush 120 is placed inside the floor brush receiving cavity 310. A guide and limiting structure (not shown) is provided on the cavity wall of the floor brush receiving cavity 310. The guide and limiting structure assists in the docking of the floor brush 120 with the floor brush receiving cavity 310. Preferably, the guide and limiting structure is a guide surface formed on the cavity wall of the floor brush receiving cavity 310. Specifically, guide surfaces are provided on the side walls around the opening of the floor brush receiving cavity 310. The guide surfaces are inclined straight surfaces. During the docking process between the vacuum cleaner 100 and the base station 200, the guide surfaces guide the floor brush 120, ensuring smooth docking between the floor brush 120 and the floor brush support structure 300.

[0078] Furthermore, the floor brush receiving cavity 310 forms a sealed space after the floor brush 120 is placed on it, thereby preventing hair and dust blown off the floor brush 120 from flying into the external environment and avoiding pollution. In order to collect the hair and dust falling off the floor brush 120, a first dust collection component 320 is also provided at the bottom of the floor brush receiving cavity 310. The first dust collection component 320 can be a filter bag or a box with an open top.

[0079] In one embodiment, such as Figure 8 and Figure 9 As shown, the floor brush support structure 300 includes a first shell portion 330 and a second shell portion 340 that are separately disposed. The first shell portion 330 is located above the second shell portion 340, and the aforementioned floor brush receiving cavity 310 is formed on the first shell portion 330. The first shell portion 330 and the second shell portion 340 enclose and form a cavity 350 located inside the floor brush support structure 300. The cavity 350 is located below the floor brush receiving cavity 310, and the first dust collection member 320 is located inside the cavity 350.

[0080] The floor brush receiving cavity 310 has a dust collection port 311 at its bottom, which connects the floor brush receiving cavity 310 to the cavity 350. The first dust collection component 320 can be detachably connected to the dust collection port 311 or detachably disposed within the cavity 350. Dirt blown off the roller brush 121 can enter the first dust collection component 320 through the dust collection port 311. Figure 8 As shown, in order to facilitate the entry of dirt into the first dust collection component 320, preferably, the bottom of the floor brush receiving cavity 310 can be configured as a funnel shape that is inclined towards the dust collection port.

[0081] The first housing portion 330 and the second housing portion 340 are connected by a second connecting structure. The second connecting structure is configured such that the cavity 350 has an open state and a closed state, so as to facilitate the removal of the first dust collection component 320 and thus facilitate the replacement of the first dust collection component 320.

[0082] The second connection structure can be a hinged connection structure or a pull-out connection structure. When the second connection structure is a hinged connection structure, such as... Figure 9 As shown, one side of the first housing 330 is hinged to the second housing 340 via a hinge shaft 500, and the opposite side is engaged via a snap-fit. When the first dust collection component 320 needs to be replaced, simply release the snap-fit ​​while the vacuum cleaner 100 is not connected to the base station 200, and the first housing 330 can be flipped over to expose the first dust collection component 320.

[0083] The first shell portion 330 and the second shell portion 340 can also be connected in other ways, such as a pull-out method. The second shell portion 340 is pulled out from below the first shell portion 330. In this case, preferably, the first dust collection component 320 is detachably disposed inside the second shell portion 340, and the first dust collection component 320 can be replaced after the second shell portion 340 is pulled out. Of course, when using the pull-out method, the second shell portion 340 and the first dust collection component 320 can be the same component, with the first dust collection component 320 being the second shell portion 340.

[0084] To better clean the roller brush 121, after the vacuum cleaner 100 is connected to the base station 200, the roller brush 121 can rotate in a first direction, which is opposite to the working direction of the roller brush 121. If the roller brush 121 is stationary, the airflow blown out of the suction port 122 can only act on a certain area of ​​the roller brush 121, and cannot clean the entire roller brush. Moreover, after the roller brush 121 rotates, the centrifugal force generated helps dirt to be removed from the roller brush 121, which is more conducive to cleaning the roller brush 121.

[0085] Furthermore, after the vacuum cleaner 100 is connected to the base station 200, the roller brush 32 rotates alternately in the first direction and in the opposite direction. Compared with rotating only in the first direction, the alternating rotation provides a better self-cleaning effect, and the hair wrapped on the roller brush 121 is easier to loosen and be carried away by the airflow from the roller brush 121.

[0086] The rotation of the floor brush 120 can be driven by the floor brush motor (not shown) built into the floor brush 120, or by setting a drive structure (not shown) on the floor brush support structure 300. For example, one or more guide rollers (not shown) are set parallel to the roller brush 121 in the floor brush receiving cavity 310. The guide rollers are driven by an additional motor. The roller brush 121 abuts against the guide rollers and drives the roller brush 121 to rotate through contact. Alternatively, the roller brush 121 can also be rotated by the airflow blown out by the suction port 122.

[0087] During the cleaning process, the roller brush 121 will inevitably accumulate hair. When too much hair becomes entangled on the roller brush 121, it will affect its normal rotation. Therefore, if... Figure 1As shown, the area where the base station 200 cooperates with the floor brush 120 is also provided with a scraping member 600. The scraping member 600 extends axially along the roller brush 121. One radial side of the scraping member 600 is fixedly connected to the floor brush support structure 300, and the other radial side of the scraping member 600 abuts against the outer circumferential surface of the roller brush 121. The aforementioned "other radial side of the scraping member 600" is comb-shaped. When the roller brush 121 rotates in the first direction, the comb-shaped ends of the scraping member 600 act on the outer circumferential surface of the roller brush 121 to remove hair from the roller brush 121. The scraping members 600 are distributed near the dust collection port 311 to facilitate the removal of scraped hair into the dust collection port 311.

[0088] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, those skilled in the art can make other variations or modifications without creative effort, and all such variations or modifications should fall within the protection scope of this utility model.
