Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of cleaning tools, and particularly relates to a dust collection system. BACKGROUND

[0002] The dust collection system comprises a dust collector and a base station. The dust collector can be separated from the base station to perform dust collection cleaning work alone. After the dust collector finishes cleaning, the dust collector can be placed on the base station. The base station charges the dust collector, so that the dust collector can be used continuously. The dust collector comprises a dust cup assembly and a floor brush assembly. The floor brush assembly is used to contact a surface to be cleaned (such as the ground). The floor brush assembly and the dust cup assembly are connected. The floor brush assembly rolls up dirt (such as dust, garbage, and hair) on the ground and sucks it in. The dirt is introduced into the dust cup assembly. After being filtered multiple times by the dust cup assembly, the dirt is collected in the dust cup. When the dust collector finishes dust collection and is placed on the base station, the base station can suck the dirt in the dust cup into the base station through a suction device on the base station, so as to realize self-cleaning of the dust cup. However, the floor brush assembly is actually the part that contacts the ground most. Dirt is easily attached to the rolling brush of the floor brush assembly.

[0063] The present application provides a dust collection system 1000, specifically, please refer to Figures 1 to 3 In the present embodiment, the dust collection system 1000 comprises a dust collection device 100, a base station 200 and a channel switching mechanism 6. The dust collection device 100 comprises a device main body 1, a dust cup assembly 2 and a floor brush assembly 3 arranged on the device main body 1. The base station 200 comprises a base station main body 4, a first storage cavity 41 and a second storage cavity 42 arranged on the base station main body 4. The base station main body 4 is formed with a first flow guide channel connected with the dust cup assembly 2 and a second flow guide channel connected with the floor brush assembly. The first storage cavity 41 is arranged on the first flow guide channel, and the second storage cavity 42 is arranged on the second flow guide channel. Negative pressure can be formed in the first flow guide channel to guide the dirt in the dust cup assembly 2 into the first storage cavity 41. Negative pressure can be formed in the second flow guide channel to guide the dirt at the floor brush assembly 3 into the second storage cavity 42. The channel switching mechanism 6 makes at least one of the first flow guide channel and the second flow guide channel in a conductive state.

[0064] In the embodiment, the floor brush assembly 3 is used to contact the surface to be cleaned (such as the ground) to suck up the dirt (such as hair, garbage, etc.) on the surface to be cleaned and suck into the dust cup assembly 2 for storage in the dust cup assembly 2; the base station 200 comprises a base station main body 4, a first storage cavity 41 and a second storage cavity 42, wherein the base station main body 4 is formed with a first flow guide channel connected with the dust cup assembly 2 and a second flow guide channel connected with the floor brush assembly 3, and negative pressure can be formed in the first flow guide channel and the second flow guide channel, for example, the first flow guide channel can form negative pressure by the action of the suction device to guide the dirt in the dust cup assembly 2 into the first storage cavity 41, and the second flow guide channel can form negative pressure by the action of the suction device to guide the dirt at the floor brush assembly 3 into the second storage cavity 42, so as to realize the cleaning of the dust cup assembly 2 and the floor brush assembly 3 respectively, so that the cleaning effect of the dust collection device 100 is better, and the user does not need to manually clean, which is more labor-saving and better user experience; and the channel switching mechanism 6 is further provided, and at least one of the first flow guide channel and the second flow guide channel can be in a conductive state by the channel switching mechanism 6, so as to better control the dust extraction path. When the dust cup assembly 2 needs to be cleaned, the first flow guide channel can be conducted by the channel switching mechanism 6, and negative pressure is formed in the first storage cavity 41 under the action of the suction device 5, so as to suck the dirt in the dust cup assembly 2 into the first storage cavity 41; when the floor brush assembly 3 needs to be cleaned, the second flow guide channel can be conducted by the channel switching mechanism 6, and negative pressure is formed in the second storage cavity 42 under the action of the suction device 5, so as to suck the dirt on the floor brush assembly 3 into the second storage cavity 42; or both flow guide channels are opened at the same time by the channel switching mechanism 6 to clean the dust cup assembly 2 and the floor brush assembly 3 at the same time. The cleaning mode of the dust collection system 1000 is more diversified and can be more suitable for different scene use requirements, and the garbage at the dust cup assembly 2 and the floor brush assembly 3 can be stored separately to reduce the cleaning frequency of each storage cavity, or when a dust bag is arranged in each storage cavity, the frequency of replacing the dust bag can be reduced, the probability of the user contacting the dirt is reduced, and the labor intensity of the user is reduced.

[0065] It can be understood that the dust collection device 100 has a cleaning working state of being separated from the base station 200 and cleaning the surface to be cleaned separately. The dust cup assembly 2 and the floor brush assembly 3 of the dust collection device 100 are connected by a pipeline. Preferably, in combination with Figure 2 and Figure 3As shown, the dust cup assembly 2 and the floor brush assembly 3 are connected by the hard dust guide pipe. By the friction between the floor brush assembly 3 and the surface to be cleaned, the dirt on the surface to be cleaned is rolled up and sucked into the dust cup assembly 2 through the dust guide pipe, and stored in the dust cup assembly 2. After the cleaning work of the cleaning device 100 is completed, the cleaning device 100 can be placed on the base station 200 to be in the dust extraction state, and then the base station 200 can charge the cleaning device 100 and / or clean the dust cup assembly 2 and the floor brush assembly 3.

[0066] The channel switching mechanism 6 can be used flexibly. In an embodiment, the channel switching mechanism 6 can simultaneously open the first and second flow guide channels, so that the base station 200 can clean the dust cup assembly 2 and the floor brush assembly 3 at the same time, and the cleaning efficiency is higher. In another embodiment, the channel switching mechanism 6 can open one of the flow guide channels while blocking the other flow guide channel, so that each flow guide channel works independently, the internal suction degree is larger, and the cleaning is more thorough.

[0067] It can be understood that in an embodiment, the channel switching mechanism 6 can be used as an independent component to exist outside the base station 200 and the cleaning device 100, and be used with different devices.

[0068] Preferably, the channel switching mechanism 6 is arranged on the base station main body 4 to be part of the base station 200, so that when the dust extraction work is performed, there are fewer docking components, and the dust extraction work can be realized by directly placing the cleaning device 100 on the base station 200, and the operation is simpler.

[0069] Hereinafter, the channel switching mechanism 6 arranged on the base station main body 4 will be mainly described as an example, and other arrangement modes can be adapted and implemented.

[0070] Preferably, the channel switching mechanism 6 makes the first and second flow guide channels be selectively opened, that is, when the cleaning device 100 is placed on the base station 200 to be in the dust extraction state, only one of the first and second flow guide channels is in the open state, so that the suction force of the dust extraction airflow formed in the first or second flow guide channel is larger, and the dirt in the dust cup assembly 2 or the dirt on the floor brush assembly 3 can be better sucked and cleaned, so that the cleaning effect is better.

[0071] Preferably, the channel switching mechanism 6 has a first working state in which the first flow channel is open and the second flow channel is blocked, and a second working state in which the second flow channel is open and the first flow channel is blocked. When the suction device 5 is working, a negative pressure is formed in the first flow channel in the first working state, and dirt in the dust cup assembly 2 is sucked out through the first flow channel to clean the dust cup assembly 2. When the suction device 5 is working, a negative pressure is formed in the second flow channel in the second working state, and dirt on the floor brush assembly 3 is sucked out through the second flow channel to clean the floor brush assembly 3.

[0072] Moreover, the dust collection system further comprises a suction device 5, the first flow channel is used to connect the air inlet end of the suction device 5 and the dust cup assembly 2, and the second flow channel is used to connect the air inlet end of the suction device 5 and the floor brush assembly 3. When the suction device 5 is working, a negative pressure is formed in the first flow channel, and dirt in the dust cup assembly 2 is sucked into the first flow channel and then into the first storage cavity 41 under the action of the negative pressure through the connection between the first flow channel and the dust cup assembly 2. When the suction device 5 is working, a negative pressure is formed in the second flow channel, and dirt in the floor brush assembly 3 is sucked into the second flow channel and then into the second storage cavity 42 under the action of the negative pressure through the connection between the second flow channel and the floor brush assembly 3, so that the dust cup assembly 2 and the floor brush assembly 3 are better cleaned.

[0073] It can be understood that the suction device 5 can be arranged outside the base station 200 as a separate component or on an external device, or the suction device 5 is arranged on the base station main body 4 to form a part of the base station 200, so that the structure of the entire dust collection system 1000 is more compact and the use is more convenient.

[0074] The channel switching mechanism 6 is located upstream of the suction device 5 in the flow direction of the dust extraction airflow, i.e. in the first working state or the second working state, and controls the opening and closing of the communication path between the suction device 5 and the dust cup assembly 2 or the communication path between the suction device 5 and the floor brush assembly 3. The first interface 451 is formed on the base body 4 and is connected to the suction inlet of the suction device 5 and is in communication with the dust cup assembly 2. The second interface 441 is formed on the base body 4 and is in communication with the floor brush assembly 3. When the cleaning device 100 is placed on the base station 200, the dust cup assembly 2 is in communication with the first interface 451, and the floor brush assembly 3 is in communication with the second interface 441. Specifically, the channel switching mechanism 6 can be arranged on the pipeline connecting the suction inlet of the suction device 5 and the first storage cavity 41, and / or on the pipeline connecting the first storage cavity 41 and the first interface 451, and / or on the pipeline connecting the suction inlet of the suction device 5 and the second storage cavity 42, and / or on the pipeline connecting the second storage cavity 42 and the second interface 441. According to the relative positions of the dust cup assembly 2 and the floor brush assembly 3, the position of the channel switching mechanism 6 can be reasonably arranged.

[0075] Preferably, at least part of the first flow channel and at least part of the second flow channel are arranged integrally to form a merging section 474. The channel switching mechanism 6 is located in the merging section 474, or the channel switching mechanism 6 is located at the junction of the first flow channel and the merging section 474 and at the junction of the second flow channel and the merging section 474. The size of the channel switching mechanism 6 can be relatively smaller, so as to better control the opening and closing of the first flow channel and the second flow channel.

[0076] Further, in the flow direction of the dust extraction airflow, the merging section 474 is formed downstream of the first storage cavity 41 and downstream of the second storage cavity 42, so that the merging section 474 is closer to the suction device 5, and the effectiveness of the opening and closing control of each flow channel is better. In the second working state, the first storage cavity 41 is avoided from forming a negative pressure, or in the first working state, the second storage cavity 42 is avoided from forming a negative pressure, so as to avoid the loss of part of the airflow and affect the dust extraction effect.

[0077] In combination with Figure 5 and Figure 8As shown, a first opening 4711 is formed at the junction of the first flow channel and the merging section 474, and a second opening 4721 is formed at the junction of the second flow channel and the merging section 474; the channel switching mechanism 6 is configured to block or open the first opening 4711 and the second opening 4721, thereby achieving the opening and blocking of the first flow channel and the second flow channel. Specifically, when in the first working state, the channel switching mechanism 6 opens the first opening 4711 and blocks the second opening 4721; when in the second working state, the channel switching mechanism 6 opens the second opening 4721 and blocks the first opening 4711.

[0078] It can be understood that there are many ways to achieve the opening and blocking of the first flow channel and the second flow channel. In an embodiment, the channel switching mechanism 6 can include a first shielding plate and a second shielding plate arranged movably, the first shielding plate is movably arranged in the first flow channel, when the first shielding plate forms a barrier in the first flow channel, thereby blocking the first flow channel, when the first shielding plate does not form a barrier in the first flow channel, then the first flow channel is in an open state; the second shielding plate can be arranged in the same way as the first shielding plate, by forming a barrier on the second flow channel with the second shielding plate to block the second flow channel, when the second shielding plate does not form a barrier on the second flow channel, then the second flow channel is in an open state. Preferably, the channel switching mechanism 6 is rotatably arranged in the base station main body 4 to switch between the first working state and the second working state. The first shielding plate and the second shielding plate are both rotatably arranged, and the switching between the first working state and the second working state is achieved by rotating the first shielding plate and the second shielding plate. Moreover, the first shielding plate and the second shielding plate can also make the two flow channels simultaneously in an open state to simultaneously clean the dust cup assembly 2 and the floor brush assembly 3; or, the first shielding plate and the second shielding plate can also make the two flow channels simultaneously in a blocked state to avoid the base station 200 from forming a false suction when the cleaning equipment 100 is not placed on the base station 200.

[0079] The first shielding plate and the second shielding plate can be synchronously moved, or the first shielding plate and the second shielding plate are non-synchronously moved. For example, in the first working state, the first shielding plate is arranged to open the first opening 4711, and the second shielding plate is arranged to close the second opening 4721. When switching from the first working state to the second working state, the first shielding plate moves towards the direction of closing the first opening 4711, and at the same time, the second shielding plate moves towards the direction of opening the second opening 4721, so that the state switching efficiency is higher. When the first shielding plate and the second shielding plate are non-synchronously moved, after the first shielding plate moves towards the direction of closing the first opening 4711 and completely closes the first opening 4711, the second shielding plate can be further driven to move, so that the second shielding plate completely opens the second opening 4721. The first shielding plate and the second shielding plate can be moved one by one, so that the first shielding plate and the second shielding plate can be controlled separately, and the flexibility is better.

[0080] Preferably, in combination Figures 4 to 7 As shown, the channel switching mechanism 6 comprises a blocking piece 61 rotatably arranged in the merging section 474. The first opening 4711 and the second opening 4721 are arranged along the circumference of the blocking piece 61. The blocking piece 61 is used to close the first opening 4711 or the second opening 4721. One blocking piece 61 can realize the switching of the two working states, the structure is simpler, and the occupied space is smaller.

[0081] The blocking piece 61 can be manually driven to rotate, and the cost is lower.

[0082] Preferably, the channel switching mechanism 6 further comprises a blocking driving structure connected with the blocking piece 61. The blocking driving structure drives the blocking piece 61 to rotate, so that the blocking piece 61 can close the first opening 4711 or the second opening 4721. The switching work of the channel switching mechanism 6 can be realized more automatically by the blocking driving structure, the use is more convenient, and the intelligent effect is better. The blocking driving structure can be arranged as a driving motor or an air cylinder.

[0083] It should be noted that when the dust collection equipment 100 is placed on the base station 200, the dust cup assembly 2 is located above the floor brush assembly 3 and is arranged in a staggered manner along the up-down direction with the floor brush assembly 3. Therefore, the first docking port 451 on the base station 200 is located above the second docking port 441. In the utility model, the description of the position can be used as a reference unless otherwise specified. Specifically, the base station 200 further comprises a dust guide cavity 45 and a floor brush containing cavity 44. One end of the dust guide cavity 45 is in communication with the first storage cavity 41, and the other end forms the first docking port 451 for docking with the dust cup assembly 2. Preferably, in combination Figure 3 , Figure 4 , Figure 6 and Figure 7As shown, the dust guide cavity 45 is generally funnel-shaped, the upper end of the dust guide cavity 45 is flared to form a first interface 451, and the lower end of the dust guide cavity 45 is tapered to form a through hole in communication with the first storage cavity 41. The channel switching mechanism 6 is arranged on the path of the suction device 5 in communication with the first storage cavity 41. In the first working state, in combination with Figure 3 The dashed arrows indicate the direction of the airflow, which enters the dust guide cavity 45 from the dust cup assembly 2, flows through the first storage cavity 41, and then enters the suction device 5. The brush containing cavity 44 is used to contain at least part of the brush assembly 3. The second interface 441 is arranged on one side of the brush containing cavity 44 and is in communication with the second storage cavity 42. The shape of the brush containing cavity 44 is adapted to the shape of the brush assembly 3 to better cover the rolling brush 32 of the brush assembly 3, so that a better negative pressure is formed around the rolling brush 32, and the cleaning effect of the rolling brush 32 is better. In the second working state, as shown in FIG. 6B, the dashed arrows indicate the direction of the airflow, which enters the second storage cavity 42 from the brush containing cavity 44 through the second interface 441, and then enters the suction device 5 after flowing through the channel switching mechanism 6. Figure 8 The dashed arrows indicate the direction of the airflow, which enters the dust guide cavity 45 from the dust cup assembly 2, flows through the first storage cavity 41, and then enters the suction device 5. The brush containing cavity 44 is used to contain at least part of the brush assembly 3. The second interface 441 is arranged on one side of the brush containing cavity 44 and is in communication with the second storage cavity 42. The shape of the brush containing cavity 44 is adapted to the shape of the brush assembly 3 to better cover the rolling brush 32 of the brush assembly 3, so that a better negative pressure is formed around the rolling brush 32, and the cleaning effect of the rolling brush 32 is better. In the second working state, as shown in FIG. 6B, the dashed arrows indicate the direction of the airflow, which enters the second storage cavity 42 from the brush containing cavity 44 through the second interface 441, and then enters the suction device 5 after flowing through the channel switching mechanism 6.

[0084] The base station body 4 includes a base, a support rod, and a cylindrical portion. The suction device 5 and the merging section 474 are arranged on the base to ensure the stability of the base. The support rod connects the base and the cylindrical portion to support the cylindrical portion at a certain height, so that the dust guide cavity 45 can better interface with the dust cup assembly 2. The cylindrical portion is generally cylindrical, and the first storage cavity 41 and the dust guide cavity 45 are arranged in the cylindrical portion. Preferably, the dust guide cavity 45, the first storage cavity 41, and the cylindrical portion are coaxially arranged. The second storage cavity 42 is also arranged on the base, and the opening of the brush containing cavity 44 is exposed from the top of the base to facilitate the placement of the brush assembly 3.

[0085] The first flow guide channel includes a first pipe 46 in communication with the first storage cavity 41. The first pipe 46 is arranged in the support rod and extends in the up-down direction. Preferably, the first pipe 46 is coaxially arranged with the first storage cavity 41. The base station 200 further includes a docking cavity 47 arranged on the base station body 4. Specifically, the docking cavity 47 is arranged in the base and is arranged close to the air outlet end of the suction device 5. The docking cavity 47 is located between the suction device 5 and the second storage cavity 42. In combination with Figure 5 and Figure 8As shown, the docking cavity 47 has a first docking passage 471 opposite to the other end of the first pipe 46, a second docking passage 472 opposite to the second storage cavity 42, a third docking passage 473 opposite to the air inlet end of the suction device 5, and a merging section 474 formed at the intersection of the first docking passage 471, the second docking passage 472 and the third docking passage 473; a first opening 4711 is connected to the first docking passage 471 and the merging section 474, and a second opening 4721 is connected to the second docking passage 472 and the merging section 474, and the blocking member 61 is rotatably arranged in the merging section 474. The first docking passage 471 is in a cylindrical shape to be connected to the other end of the first pipe 46; the end of the second docking passage 472 connected to the second storage cavity 42 is in a trumpet shape, so that the airflow can better enter the second docking passage 472, avoiding air leakage. Moreover, the base station 200 further comprises a filter arranged on the path connected to the second storage cavity 42 and the second opening 4721, and the trumpet-shaped second docking passage 472 provides sufficient space for the filter. The filter can be configured to filter the sea pa. The third docking passage 473 is also in a substantially cylindrical shape to be opposite to the air inlet end of the suction device 5. The channel switching mechanism 6, the suction device 5 and the second storage cavity 42 are integrated on the base, so that the center of gravity of the entire base station 200 is lower, thus more stable and less likely to tip over.

[0086] Preferably, in combination Figure 5 and Figure 8 As shown, the first opening 4711 and the second opening 4721 are located on the same circular arc surface. The blocking member 61 comprises a blocking shaft 611 and a blocking block 612 arranged on the radial side of the blocking shaft 611, and the blocking block 612 has a blocking surface extending along the circumferential direction thereof, and the blocking surface is used to block the first opening 4711 or the second opening 4721; the air duct switching structure further comprises a sealing member 62 arranged on the blocking surface, so that the blocking effect on the first flow guide passage or the second flow guide passage is better, and air leakage is less likely to occur.

[0087] Moreover, the blocking member 61 can be rotated in both directions to switch between the first working state and the second working state, so that the switching path is shorter, and thus the working efficiency is higher.

[0088] In one embodiment, in the flow direction of the dust extraction airflow along the second guide channel, the first opening 4711 is located between the second opening 4721 and the third docking channel 473. When in the first working state, the airflow can directly flow from the first opening 4711 through the confluence section 474 and then into the third docking channel 473. Since the sealing member 61 blocks the flow path between the second opening 4721 and the third docking channel 473 when in the second working state, a through hole is provided on the sealing member 61. When in the second working state, the through hole connects the second opening 4721 and the third docking channel 473, so that the airflow can flow from the second opening 4721 through the hole into the third docking channel 473.

[0089] For the dust cup assembly 2, the dust cup assembly 2 includes a dust cup cavity 21 and a dust cup cover 22 movably disposed on the dust cup cavity 21. The dust cup cavity 21 has an opening. Preferably, the opening of the dust cup cavity 21 is located at the bottom of the dust cup cavity 21. The dust cup cover 22 can open and close the opening of the dust cup cavity 21. When the vacuuming device 100 is placed on the base station 200 and the dust cup cover 22 is open, the opening and the first pair of interfaces 451 are connected and conductive. The dirt in the dust cup cavity 21 can enter the dust guiding cavity 45 under its own gravity and the suction force of the suction device 5, and enter the first storage cavity 41 under the guidance of the dust guiding cavity 45.

[0090] Furthermore, the dust cup assembly 2 also includes a locking structure and an elastic reset member connecting the dust cup cavity 21 and the dust cup cover 22. The locking structure is used to lock and unlock the dust cup cover 22. The base station body 4 is provided with an unlocking part. When the vacuum cleaner 100 is placed on the base station 200, the locking structure can be unlocked under the action of the unlocking part, and the dust cup cover 22 is in the closed cavity position under the action of the elastic reset member. When in the first working state and the suction device 5 is turned on, the dust cup cover 22 can be opened under the action of the suction airflow in the first guide channel. When the vacuum cleaner 100 is placed on the base station 200, the locking mechanism can be unlocked by unlocking the locking part. However, at this time, the dust cup cover 22 is still in the state of closing the dust cup cavity 21. Only when the channel switching structure is in the second working state and the suction device 5 is turned on to form a negative pressure in the first flow channel can the dust cup cover 22 open the dust cup cavity 21 under the action of the negative pressure, so that the dirt in the dust cup cavity 21 can be sucked out. This ensures that when the vacuum system 1000 is in the second working state, the dirt in the dust cup assembly 2 will not fall out indiscriminately, or even stick to the dust cup cavity 21 and cause secondary pollution. It can also avoid the blockage of the first flow channel and affect the normal operation of the base station 200.

[0091] Additionally, the base station 200 also includes a cover plate 43, which covers the second pair of interfaces 441 and is rotatable toward the second storage cavity 42; when in the first working state, such asFigure 5 As shown, the cover plate 43 is configured to block the second pair of interfaces 441. In the second operating state, as... Figure 8 As shown, the cover plate 43 can open the second pair of interfaces 441. When the channel switching mechanism 6 is in the first working state, the cover plate 43 is in a closed second docking configuration, and the floor brush receiving cavity 44 and external dirt will not enter the second storage cavity 42; when the channel switching mechanism 6 is in the second working state, under the action of the suction device 5, a negative pressure is formed in the second storage cavity 42. Under the action of the negative pressure, the cover plate 43 can be driven to rotate to open the second pair of interfaces 441, so that the dirt in the floor brush receiving cavity 44 can enter the second storage cavity 42.

[0092] For the floor brush component 3, combined with Figure 4 and Figure 5 As shown, the floor brush assembly 3 includes a floor brush housing 31 and a roller brush 32 rotatably mounted on the floor brush housing 31. When the vacuum cleaner 100 is performing vacuuming operations, the roller brush 32 has a rotational stroke along a first direction. The rotation of the roller brush 32 rubs against the surface to be cleaned, thereby improving the cleaning ability of the vacuum cleaner 100. When the vacuum cleaner 100 is placed on the base station 200 and is in a second working state, the roller brush 32 has a rotational stroke along the first direction and / or along a second direction, wherein the first and second directions are opposite. The rotation of the roller brush 32 makes it easier for dirt on the roller brush 32 to fall into the floor brush receiving cavity 44 for removal, thereby improving the cleaning effect of the roller brush 32.

[0093] Furthermore, a scraper is provided on one side of the floor brush housing 31. The scraper can contact the roller brush 32. When the roller brush 32 rotates, it can scrape off the dirt wrapped around the roller brush 32, which can help clean the roller brush 32.

[0094] The rotation of the roller brush 32 within the floor brush accommodating cavity 44 can be either autonomous or passive.

[0095] In one embodiment, the base station 200 further includes a driving component disposed on the base station body 4. When the floor brush assembly 3 is housed within the floor brush housing cavity 44, the driving component is connected to the roller brush 32 to drive the roller brush 32 to rotate, thereby improving the cleaning efficiency of the roller brush 32. Specifically, the driving component may be movably disposed on the base station body 4. The driving component may move automatically or manually to connect with the rotation axis of the roller brush 32 when the roller brush 32 is placed in position, so that the roller brush 32 can be driven to rotate by the driving component.

[0096] In another embodiment, the roller brush 32 can be driven to rotate by the airflow formed within the floor brush receiving cavity 44. For example, the roller brush 32 can rotate on its own under the action of the suction airflow in the second guide channel; or, an auxiliary air duct is also provided in the floor brush receiving cavity 44, which generates airflow and blows it toward the roller brush 32, driving the roller brush 32 to rotate. Moreover, the airflow in the auxiliary air duct can originate from the airflow blown from the air outlet of the upper suction device 5, guiding a portion of the airflow from the air outlet of the suction device 5 into the floor brush receiving cavity 44, causing the roller brush 32 to rotate, and blowing off dirt on the sidewalls of the roller brush 32, resulting in a wider cleaning range and better cleaning effect for the floor brush assembly 3.

[0097] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structure made using the contents of the present utility model specification and drawings, or directly or indirectly applied to other related technical fields, are similarly included within the patent protection scope of the present utility model.
