Description

Technical Field

[0001] This utility model relates to the technical field of cleaning tools, specifically to a vacuuming system. Background Technology

[0002] The vacuuming system consists of a vacuum cleaner and a base station. The vacuum cleaner can operate independently of the base station for cleaning. After cleaning, the vacuum cleaner can be placed on the base station, which charges it, allowing for continuous use. The vacuum cleaner includes a dust cup assembly and a floor brush assembly. The floor brush assembly contacts the surface to be cleaned (such as the floor). The floor brush assembly and the dust cup assembly are connected. The floor brush assembly picks up and sucks up dirt (such as dust, debris, and hair) from the floor, guiding it into the dust cup assembly. After multiple filtrations, the dirt is collected in the dust cup. In traditional vacuuming systems, after the vacuum cleaner is placed on the base station, the suction device on the base station can suck the dirt from the dust cup into the base station, achieving self-cleaning of the dust cup. However, the floor brush assembly is the part that has the most contact with the floor, and its roller brush easily accumulates dirt. Traditional base stations cannot clean the floor brush assembly, requiring manual cleaning by the user, increasing the user's workload and resulting in a poor user experience. Utility Model Content

[0057] This utility model provides a dust collection system. Please refer to [link / reference]. Figure 1 , Figure 2 ,as well as Figure 6 Specifically, the vacuuming system includes a vacuuming device 1, a base station 2, and a channel switching structure 3. The vacuuming device 1 includes a device body 11, a dust cup assembly 12, and a floor brush assembly 13 disposed on the device body 11; the base station 2 includes a base station body 21, a suction device 22, and a storage cavity 23. The suction device 22 is disposed on the base station body 21, and the base station body 21 defines a first flow channel 41 that connects the air inlet of the suction device 22, the dust cup assembly 12, and the storage cavity 23. The base station body 21 also defines a second flow channel 42 that connects the air inlet of the suction device 22, the floor brush assembly 13, and the storage cavity 23; the channel switching structure 3 is disposed on the base station body 21 and is used to ensure that at least one of the first flow channel 41 and the second flow channel 42 is in a conductive state.

[0058] The floor brush assembly 13 is used to contact the surface to be cleaned (such as the ground) to clean it. When the floor brush assembly 13 is working, it can suck up dirt (such as hair, garbage, etc.) from the surface to be cleaned, suck it into the vacuum cleaner 1, and store it in the dust cup assembly 12. The base station 2 is equipped with a suction device 22 and a storage cavity 23. The suction device 22 is connected to the storage cavity 23. When the vacuum cleaner 1 is connected to the base station 2, the suction device 22 can be used to suck the dirt in the dust cup assembly 12 and the dirt on the floor brush assembly 13 into the storage cavity 23 respectively, thereby cleaning the dust cup assembly 12 and the floor brush assembly 13, improving the cleaning effect of the vacuum cleaner 1, and eliminating the need for manual cleaning by the user, resulting in a better user experience.

[0059] The channel switching structure 3 can switch between the first flow channel 41 and the second flow channel 42, allowing one or both to be open to control the suction path. When the base station 2 needs to clean the dust cup assembly 12, the channel switching structure 3 opens the first flow channel 41, creating a negative pressure in the storage cavity 23 under the action of the suction device 22, thus drawing dirt from the dust cup assembly 12 into the storage cavity 23. When the base station 2 needs to clean the floor brush assembly 13, the channel switching structure 3 opens the second flow channel 42, creating a negative pressure in the storage cavity 23 under the action of the suction device 22, thus drawing dirt from the floor brush assembly 13 into the storage cavity 23. Alternatively, when cleaning both the floor brush assembly 13 and the dust cup assembly 12 simultaneously is required, the first flow channel 41 and the second flow channel 42 can be simultaneously activated via the channel switching structure 3. Under the action of the suction device 22, a negative pressure is formed in the storage cavity 23, thus simultaneously sucking the dirt on the floor brush assembly 13 and the dirt in the dust cup assembly 12 into the storage cavity 23. The first flow channel 41 and the second flow channel 42 share the storage cavity 23. When the first flow channel 41 and the second flow channel 42 are activated simultaneously, the number of times the user needs to replace the storage cavity 23 when cleaning the base station 2 can be reduced, optimizing the user experience and simplifying the structure.

[0060] More specifically, such as Figure 2 , Figure 4 , Figure 6 as well as Figure 7 As shown, the channel switching structure 3 has a first operating state in which the first flow channel 41 is open and the second flow channel 42 is blocked, and a second operating state in which the second flow channel 42 is open and the first flow channel 41 is blocked. In other embodiments, the channel switching structure 3 also has a third operating state in which both the first flow channel 41 and the second flow channel 42 are open.

[0061] Furthermore, when only one of the first guide channel 41 and the second guide channel 42 is in a conducting state, the suction force of the suction device 22 is greater, which can better remove dirt from the dust cup assembly 12 or the floor brush assembly 13, resulting in a better cleaning effect.

[0062] like Figure 6 and Figure 7 As shown, when the channel switching structure 3 is in the first working state, the first guide channel 41 is open and the second guide channel 42 is blocked. The suction device 22 suctions, and the dirt in the dust cup assembly 12 is sucked into the storage chamber 23. The suction airflow passes from the dust cup assembly 12 through the storage chamber 23 and reaches the air inlet of the suction device 22. Figure 2 and Figure 4As shown, when the channel switching structure 3 is in the second working state, the second guide channel 42 is open and the first guide channel 41 is blocked. The suction device 22 draws in dirt from the floor brush assembly 13 into the storage chamber 23. The suction airflow passes from the floor brush assembly 13 through the storage chamber 23 and reaches the air inlet of the suction device 22. When the channel switching structure 3 is in the third working state, both the first guide channel 41 and the second guide channel 42 are open. The suction device 22 draws in dirt from both the floor brush assembly 13 and the dust cup assembly 12 into the storage chamber 23. The airflow passes from the floor brush assembly 13 and the dust cup assembly 12 through the storage chamber 23 and reaches the air inlet of the suction device 22.

[0063] The channel switching structure 3 can be located upstream of the storage cavity 23 in the direction of airflow, thus facilitating the sharing of a single storage cavity 23 by the first guide channel 41 and the second guide channel 42. Switching between the first guide channel 41 and / or the second guide channel 42 upstream of the storage cavity 23 allows all suctioned contaminants to enter the storage cavity 23. More specifically, the channel switching structure 3 is located on the base station body 21 and at the inlet 231 of the storage cavity 23.

[0064] The storage cavity 23 can have only one inlet 231. In this case, the first guide channel 41 and the second guide channel 42 share the same inlet 231, meaning that all the sucked-up waste enters the storage cavity 23 through this inlet 231. Of course, the number of inlets 231 in the storage cavity 23 can also match the number of guide channels. For example, if there are two guide channels, then there are two inlets 231 in the storage cavity 23.

[0065] In one feasible implementation, the storage cavity 23 has two inlets 231, namely a first inlet and a second inlet, the first inlet being located on the first guide channel 41 and the second inlet being located on the second guide channel 42. When dirt in the dust cup assembly 12 is sucked in, it enters the storage cavity 23 through the first inlet, and when dirt on the floor brush assembly 13 is sucked in, it enters the storage cavity 23 through the second inlet.

[0066] It is worth noting that the first flow channel 41 and the second flow channel 42 may be at least partially integrated. For example, the portion from the storage cavity 23 to the air inlet of the suction device 22 may be shared by the first flow channel 41 and the second flow channel 42. Alternatively, the portion from the inlet 231 of the storage cavity 23 to the air inlet of the suction device 22 may be shared. The fact that the first flow channel 41 and the second flow channel 42 may be at least partially integrated simplifies the structure.

[0067] More specifically, the first guide channel 41 and the second guide channel 42 are at least partially integrated to form a confluence section 43. The channel switching structure 3 may be located upstream of the confluence section 43 along the flow direction of the suction airflow, thus selectively blocking the portion of the first guide channel 41 upstream of the confluence section 43 and the portion of the second guide channel 42 upstream of the confluence section 43. Alternatively, the channel switching structure 3 may not block the portion of the first guide channel 41 upstream of the confluence section 43, nor the portion of the second guide channel 42 upstream of the confluence section 43, in which case it is in a third working state. Alternatively, the channel switching structure 3 may be located at the junction of the first guide channel 41 and the confluence section 43, or at the junction of the second guide channel 42 and the confluence section 43.

[0068] like Figure 4 and Figure 7 As shown, a first opening 411 is provided at the junction of the first guiding channel 41 and the confluence section 43, and a second opening 421 is provided at the junction of the second guiding channel 42 and the confluence section 43. The channel switching structure 3 can selectively block the first opening 411 and the second opening 421. When the channel switching structure 3 blocks the first opening 411, the first guiding channel 41 is blocked. When the channel switching structure 3 blocks the second opening 421, the second guiding channel 42 is blocked.

[0069] The channel switching structure 3 can be a rotating component installed inside the base station body 21, thus blocking the first opening 411 and the second opening 421 by rotation. Specifically, the channel switching structure 3 is rotatably disposed inside the base station body 21 and has a rotational stroke between the first opening 411 and the second opening 421. When the channel switching mechanism rotates to the first opening 411, the channel switching structure 3 blocks the first opening 411; when the channel switching mechanism rotates to the second opening 421, the channel switching structure 3 blocks the second opening 421.

[0070] In one feasible implementation, such as Figure 4 and Figure 7The channel switching structure 3 includes a rotating shaft 31 and a plug structure 32 fixed on the rotating shaft 31. The plug structure 32 and the rotating shaft 31 may or may not be able to rotate relative to each other. The base station 2 also includes a rotation drive component. When the plug structure 32 and the rotating shaft 31 cannot rotate relative to each other, the rotation drive component is driven to the rotating shaft 31 or the plug structure 32. When the plug structure 32 and the rotating shaft 31 can rotate relative to each other, the rotation drive component is driven to the plug structure 32. Specifically, when the plug structure 32 rotates to the first opening 411, the first opening 411 is blocked; when the plug structure 32 rotates to the second opening 421, the second opening 421 is blocked. More specifically, for ease of operation, the first opening 411 and the second opening 421 are arranged adjacent to each other, and the plug structure 32 may be, but is not limited to, a fan-shaped structure.

[0071] In other feasible embodiments, the channel switching structure 3 may also include a spherical plug, which is disposed at the first opening 411 and the second opening 421, and has at least one through channel. In use, the first flow channel 41 and the second flow channel 42 can be opened or blocked by rotating the spherical plug.

[0072] Taking a spherical plug with a through channel as an example, one end of the through channel can be selectively connected to either the first opening 411 or the second opening 421, and the other end can be selectively connected to the inlet of the storage cavity 23. Alternatively, one end of the through channel can be neither connected to the first opening 411 nor the second opening 421; in this case, the channel switching structure 3 is in its third working state. Alternatively, the spherical plug can have two through channels, which can be selectively located on the first guide channel 41 and the second guide channel 42, respectively. The specific configuration can be determined as needed and is not specifically limited here.

[0073] In addition, base station 2 also includes a dust guiding chamber 24, which has a first pair of interfaces 241. When the vacuum cleaner 1 is connected to base station 2, the first pair of interfaces 241 are connected to the dust cup assembly 12. Base station 2 also includes a second connecting channel 26, one end of which is connected to the storage chamber 23 and the other end of which is connected to the dust guiding chamber 24. The dust cup assembly 12, the second connecting channel 26, the storage chamber 23, and the air inlet of the suction device 22 together define a first flow guiding channel 41. The second connecting channel 26 may be, but is not limited to, a second connecting pipe.

[0074] Furthermore, to facilitate smoother suction of contaminants from the dust cup assembly 12 during suction by the suction device 22, the dust cup assembly 12 is located upstream of the storage chamber 23. The dust cup assembly 12 also has an opening 1212 that mates with the first pair of interfaces 241. The opening 1212 may, but is not limited to, be located at the bottom of the dust cup assembly 12. Thus, when the dust cup assembly 12 is opened, the contaminants within it can move downwards under gravity, reducing the suction force required to transport the contaminants from the dust cup assembly 12 to the storage chamber 23; furthermore, it facilitates the complete removal of contaminants from the dust cup assembly 12.

[0075] like Figure 3 As shown, the dust cup assembly 12 includes a dust cup body 121 and a dust cup cover 122. A dust cup cavity 1211 with an opening 1212 at one end is formed within the dust cup body 121. The dust cup cover 122 is mounted on the dust cup body 121 and can optionally cover the opening 1212. When the vacuum cleaner 1 is connected to the base station 2 and the dirt inside the dust cup assembly 12 needs to be cleaned, the dust cup cover 122 is open (i.e., not covering the opening 1212). More specifically, the dust cup cover 122 has a closed state covering the opening 1212 and an open state not covering the opening 1212. When the vacuum cleaner 1 is connected to the base station 2 and the dust cup cover 122 is in the open state, the opening 1212 is connected to the first pair of interfaces 241.

[0076] To ensure that the dust cup cover 122 is only opened when it is necessary to clean the dirt inside the dust cup assembly 12, the dust cup assembly 12 also includes a locking structure and an elastic element. The locking structure is connected to the dust cup body 121 and the dust cup cover 122, and has a locked state that locks the dust cup body 121 and the dust cup cover 122 and restricts the opening of the dust cup cover 122, as well as an unlocked state. The elastic element is located between the dust cup body 121 and the dust cup cover 122. When the locking structure is in the locked state, the dust cup cover 122 and the dust cup body 121 are locked and in a closed state. When the locking structure is in the unlocked state, the dust cup cover 122 and the dust cup body 121 are unlocked and remain closed under the action of the elastic restoring force of the elastic element. At this time, it is necessary to open the dust cup cover 122 by external force or by negative pressure. This can prevent the dirt in the dust cup assembly 12 from entering the base station 2 when cleaning the dirt on the ground brush assembly 13 due to the direct opening of the dust cup cover 122, and accumulating at the channel switching structure 3. This can easily cause the channel switching structure 3 to be jammed by dirt when switching the flow channel.

[0077] More specifically, the base station body 21 is equipped with an unlocking part. When the vacuum cleaner 1 is connected to the base station 2, the unlocking part unlocks the locking structure, and the dust cup cover 122 remains closed under the elastic restoring force of the elastic element. Taking the unlocking part as an extension part and the locking structure as a snap-fit ​​structure as an example, when the vacuum cleaner 1 is connected to the base station 2, the unlocking part extends the locking structure, thus unlocking the locking structure. When the suction device 22 is working and the first guide channel 41 is open, the dust cup cover 122 opens under the action of the suction airflow.

[0078] In one feasible embodiment, the elastic element is a compression spring. When the dust cup cover 122 is closed on the dust cup body 121, the elastic element is in a relaxed or compressed state; when the dust cup cover 122 is opened relative to the dust cup body 121, the elastic element continues to be compressed. Therefore, when it is necessary to open the dust cup cover 122, the elastic restoring force of the elastic element needs to be overcome, so that the dust cup cover 122 remains closed when the locking structure is unlocked.

[0079] The dust cup cover 122 can be opened by a driving structure or by suction airflow. In this embodiment, the dust cup cover 122 is rotatably mounted on the dust cup body 121, and the opening direction of the dust cup cover 122 is the same as the flow direction of the suction airflow. Thus, the dust cup cover 122 can be opened by suction airflow when the first guide channel 41 is open and the suction device 22 is suctioning.

[0080] In addition, base station 2 also includes a floor brush receiving cavity 27. When the vacuum cleaner 1 is connected to base station 2, the floor brush assembly 13 is at least partially housed within the floor brush receiving cavity 27. The floor brush receiving cavity 27 can support and house the floor brush assembly 13 when the vacuum cleaner 1 is connected to base station 2, and can also be sealed to the suction port of the floor brush assembly 13 to ensure the cleaning effect of the suction airflow on the floor brush assembly 13.

[0081] Base station 2 also includes a first connection channel 25, one end of which is connected to storage cavity 23 and the other end is connected to ground brush accommodating cavity 27. The ground brush assembly 13, the first connection channel 25, the storage cavity 23, and the air inlet of suction device 22 together define a second flow channel 42. The first connection channel 25 may be, but is not limited to, a first connecting pipe.

[0082] The floor brush assembly 13 includes a floor brush housing 131 and a roller brush 132 rotatably mounted on the floor brush housing 131. When the suction device 22 is working and the second flow channel 42 is open, the roller brush 132 rotates forward and / or reverse. It should be noted that in this invention, the direction of rotation when the user uses the vacuum cleaner 1 to clean the surface to be cleaned is defined as forward rotation, and the opposite direction is defined as reverse rotation. When suctioning dirt from the floor brush assembly 13, reversing the roller brush 132 makes it easier for the dirt on the roller brush 132 to fall into the floor brush receiving cavity 27, thus facilitating cleaning. In other feasible embodiments, the roller brush 132 can also be rotated forward and reverse alternately to make it easier for the dirt on the roller brush 132 to fall off, resulting in a better cleaning effect.

[0083] When cleaning the floor brush assembly 13, the rotation of the roller brush 132 can be driven by the first drive unit on the floor brush assembly 13; it can also be driven by the second drive unit on the base station body 21; or it can be driven by the suction airflow to rotate the roller brush 132. There are no specific restrictions here, and it can be determined according to actual needs.

[0084] More specifically, taking the roller brush 132 rotating in the first direction during cleaning as an example, the rotation of the roller brush 132 is driven by the first driving part on the floor brush assembly 13. The floor brush assembly 13 may also include the first driving part that drives the roller brush 132 to rotate. The first driving part is driven to connect with the roller brush 132. When the vacuum cleaner 1 is connected to the base station 2 and the second flow channel 42 is open, the first driving part drives the roller brush 132 to rotate in the same or opposite direction as the first direction.

[0085] The rotation of the roller brush 132 is driven by the second drive unit on the base station body 21. The base station body 21 may be provided with a second drive unit. When the vacuum cleaner 1 is connected to the base station 2, the second drive unit is driven to connect with the roller brush 132 and can drive the roller brush 132 to rotate in the same or opposite direction as the first direction.

[0086] The rotation of the roller brush 132 is driven by the suction airflow. This can be achieved by connecting the vacuuming device 1 to the base station 2 and opening the second flow channel 42. When the suction device 22 is suctioning, the roller brush 132 rotates in the same or opposite direction as the first direction under the action of the suction airflow.

[0087] In addition, to improve the cleaning effect, the base station 2 also includes a contact member rotatably disposed in the floor brush receiving cavity 27. The contact member is arranged parallel to the roller brush 132 and can contact the roller brush 132. In this way, when cleaning the floor brush assembly 13, the contact member contacts and scrapes the roller brush 132, which can help to scrape off the dirt on the roller brush 132 and improve the cleaning effect.

[0088] The contact element can rotate under the action of suction airflow; alternatively, the base station body 21 can be equipped with a third driving unit, which is connected to the contact element to drive it to rotate, thereby rotating the roller brush 132. In this embodiment, the contact element can be, but is not limited to, one or more guide rollers. When the contact element is multiple guide rollers, the multiple guide rollers are arranged in parallel and distributed on the outer periphery of the roller brush 132, which can improve the cleaning effect.

[0089] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structure made using the contents of this utility model specification and drawings, or directly or indirectly applied to other related technical fields, are similarly included within the patent protection scope of this utility model.
