Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, and more specifically, to a cleaning system. Background Technology

[0002] With the improvement of living standards, handheld vacuum cleaners are becoming increasingly popular due to their compact and portable advantages. Handheld vacuum cleaners typically use a fan to generate negative pressure to suck up debris and other impurities into a dustbin. After use, the dustbin is opened to empty it. However, during this process, dust can easily scatter, causing secondary pollution. To solve this problem, a vacuum cleaner base station is usually included. The base station serves as a holder for the vacuum cleaner and also allows for its cleaning. When users need to empty the dustbin, they can place the vacuum cleaner inside the base station, which then opens the vacuum cleaner's lid, allowing the dustbin to be emptied and the vacuum cleaner cleaned.

[0003] Currently, when a vacuum cleaner needs to be placed on a base station for cleaning, the user must first lift the entire vacuum cleaner and place it on the base station to complete the docking. After the base station finishes cleaning the vacuum cleaner, the user needs to lift the vacuum cleaner again to separate it from the base station. This operation method is not only laborious, but also has a poor user experience. Utility Model Content

[0025] To achieve the above objectives, this utility model provides another cleaning system, including a base station and a vacuum cleaner docked with the base station.

The dust cup includes a bottom wall and a peripheral wall surrounding the bottom wall, and the peripheral wall has an openable and closable dust discharge port. The base station includes a docking part, and the docking part has a dust collection port communicating with the dust discharge port. The vacuum cleaner has a push-in position where the floor brush assembly is retracted towards the base station in a first direction, and a dust collection position where the vacuum cleaner main unit discharges dust from the dust discharge port in a third direction. In the dust collection position, the dust collection port is fluidly communicating with the dust discharge port, and the first direction is not perpendicular to the third direction.

[0026] In one embodiment, the first direction and the third direction are generally horizontal or generally parallel to the surface to be cleaned.

[0030] The beneficial effects of the technical solution provided by this utility model are as follows: According to the cleaning system of this utility model, when it is necessary to clean the vacuum cleaner through the base station, the vacuum cleaner only needs to be pushed into the base station along the ground where the base station is placed to complete the docking of the vacuum cleaner with the base station. During the entire process of moving the vacuum cleaner to the base station position until the docking of the vacuum cleaner with the base station is completed, the user does not need to lift the entire vacuum cleaner off the surface to be cleaned. Whether it is the docking of the floor brush component with the base station or the docking of the vacuum cleaner body with the base station, it is all push-in type. The user does not need to make any lifting action on the vacuum cleaner. Compared with the existing docking method that requires lifting the entire vacuum cleaner and placing it on the base station, the docking method of this utility model is more labor-saving and convenient, and optimizes the user experience.

[0031] Furthermore, the dust cup adopts a side-opening cover instead of a bottom-opening cover, and the dust collection port of the base station docking part is also changed from the bottom surface of the docking part to the side surface. Compared to the bottom-opening docking design, the bottom of the dust cup and the docking part require an interference fit generated by the deformation of the elastic sealing ring to ensure the sealing between the dust collection port and the dust discharge port. This causes the elastic sealing ring and other sealing structures to generate greater resistance when sliding between the host and the docking part, affecting the docking feel. This utility model can reduce docking resistance while ensuring the docking seal. Attached Figure Description

[0049] First Embodiment

[0050] See Figures 1 to 5 This utility model provides a cleaning system, including a base station 3 and a vacuum cleaner docked with the base station 3. The vacuum cleaner includes a floor brush assembly 6, a main unit 5 with a dust cup 1, and an extension tube 4 fluidly communicating the floor brush assembly 6 and the dust cup 1. The dust cup 1 includes an openable and closable dust discharge port 111. The base station 3 includes a docking part 31, and the docking part 31 is provided with a dust collection port 311 corresponding to the dust discharge port 111. The vacuum cleaner includes a push-in position where the floor brush assembly 6 is pushed into the base station 3 in a generally horizontal direction and a dust collection position where the vacuum cleaner main unit 5 is docked with the docking part 31 in a generally horizontal direction. At the dust collection position, the dust collection port 311 is fluidly communicating with the dust discharge port 111.

[0051] When the vacuum cleaner is docked to the base station 3, it can collect dust and debris from the dust cup 1. In this vacuum cleaner configuration, one end of the extension tube 4 is connected to the vacuum cleaner main unit 5, and the other end is connected to the floor brush assembly 6. During cleaning, the user holds the vacuum cleaner main unit 5, and part of the weight of the main unit 5 is transferred to the floor brush assembly 6 through the extension tube 4. This allows the vacuum cleaner to be supported on the surface to be cleaned by the floor brush assembly 6. At the same time, the main unit 5 generates suction force, causing the floor brush assembly 6 to suck up the dust and debris from the surface to be cleaned and transport it to the dust cup 1 through the extension tube 4. When it is necessary to clean the debris collected by the vacuum cleaner, or further, when it is necessary to clean the dust and debris in the dust cup 1, the user can move the vacuum cleaner along the surface to be cleaned towards the direction in which the base station 3 is placed. After the vacuum cleaner is pushed into the base station 3 in a roughly horizontal direction with the floor brush assembly 6, the vacuum cleaner is in the pushed-in position relative to the base station 3. At this time, the user continues to push the main unit 5 of the vacuum cleaner towards the docking part 31 of the base station 3, so that the main unit 5 docks with the docking part 31 of the base station 3 in a roughly horizontal direction. After the main unit 5 docks with the docking part 31, the vacuum cleaner is in the dust collection position relative to the base station 3. At this time, the dust discharge port 111 of the dust cup 1 docks with the dust collection port 311 of the base station 3. During the cleaning process of the vacuum cleaner by the base station 3, the dust and debris in the dust cup 1 can be discharged from the dust cup 1 through the dust discharge port 111 and enter the base station 3 through the dust collection port 311 to be collected by the base station 3. With the solution of this utility model, the user does not need to lift the entire vacuum cleaner off the surface to be cleaned during the entire process of moving the vacuum cleaner to the position of the base station 3 until the vacuum cleaner docks with the base station 3. Compared with the existing docking method, it is more labor-saving and optimizes the user experience.

[0052] Furthermore, after the base station 3 has finished cleaning the vacuum cleaner, the user only needs to move the main unit 5 of the vacuum cleaner in the opposite direction to the docking process between the vacuum cleaner and the docking part 31, so that the main unit 5 of the vacuum cleaner is disengaged from the docking part 31, and then continue to move the vacuum cleaner so that the floor brush assembly 6 is disengaged from the base station 3 to complete the separation of the entire vacuum cleaner from the base station 3. Therefore, the user does not need to lift the entire vacuum cleaner during the process of the vacuum cleaner disengaging from the base station 3.

[0053] It should be noted that "pushing the floor brush assembly 6 into the base station 3" here means that the floor brush assembly 6 enters the space formed by the structure of the base station 3 for parking the floor brush assembly 6, that is, the bottom surface of the floor brush assembly 6 is not in contact with the surface to be cleaned at all; it can also mean that the floor brush assembly 6 enters the area enclosed by the base station 3 on the surface to be cleaned, that is, the bottom surface of the floor brush assembly 6 is still in contact with the surface to be cleaned; of course, it can also mean that part of the floor brush assembly 6 enters the space formed by the structure of the base station 3 for parking the floor brush assembly 6, and part of it is located in the area enclosed by the base station 3 on the surface to be cleaned, that is, at least part of the bottom surface of the floor brush assembly 6 is not in contact with the surface to be cleaned. Specifically, the base station 3 includes a receiving cavity 71 into which the floor brush assembly 6 is pushed in a generally horizontal direction. At the pushed-in position, the floor brush assembly 6 is at least partially located in the receiving cavity 71. For example, in order to ensure the integrity of the shape of the vacuum cleaner docked on the base station 3, it is better to accommodate the floor brush assembly 6 entirely in the receiving cavity 71 at the bottom of the base station 3. On the other hand, in order to ensure the smooth airflow when the base station 3 cleans the vacuum cleaner, it is possible to consider exposing the position of the floor brush assembly 6 with the suction port outside the receiving cavity 71 of the base station 3.

[0054] See Figures 4 to 5 In one embodiment, the base station 3 includes a base 7 and a docking part 31 with a docking interface 312. The base 7 has a receiving cavity 71. The opening 711 of the receiving cavity 71 and the docking interface 312 of the docking part 31 face the same side in the horizontal direction. With this configuration, the user can push the floor brush assembly 6 and the main unit 5 of the vacuum cleaner into and dock them with the base station 3 in the same direction. The operation is simple and there is no need to adjust the direction of the main unit 5 relative to the base station 3 during the docking process. At the same time, it can avoid interference between the vacuum cleaner and the base station 3 during docking.

[0055] Furthermore, the base 7 is provided with a floor brush limiting part 72, which is used to limit the displacement of the floor brush assembly 6 relative to the base station 3, so as to prevent the floor brush assembly 6 from moving relative to the base station 3 during the process of the vacuum cleaner moving from the push-in position to the dust collection position and docking with the base station 3, causing the floor brush assembly 6 to detach from the base station 3 again when the host 5 docks with the docking part 31, thus affecting the docking effect.

[0056] In one embodiment, the base 7 includes a guide portion and a floor brush limiting portion 72. The guide portion can guide the floor brush assembly 6 from the surface to be cleaned into the receiving cavity 71 of the base 7 in a generally horizontal direction. The limiting portion on the base 7 can limit the position of the floor brush assembly 6 after it is pushed into the receiving cavity 71.

[0057] Specifically, the guide section includes a guide base plate 73 located at the opening 711 of the receiving cavity 71. The guide base plate 73 guides the movement direction of the floor brush assembly 6 when the user pushes the vacuum cleaner towards the base station 3, thereby limiting the docking direction of the vacuum cleaner relative to the base station 3, making the docking more accurate and less prone to deviation. The floor brush limiting section 72 includes a groove 721 provided on the guide base plate 73. The floor brush assembly 6 includes an auxiliary wheel 61. When the floor brush assembly 6 enters the receiving cavity 71 of the base 7 from the cleaning surface through the guide base plate 73, the auxiliary wheel 61 falls into the groove 721 to achieve limiting, at which time the vacuum cleaner is in the pushed-in position relative to the base station 3.

[0058] In another embodiment, the brush limiting part 72 is disposed within the receiving cavity 71. In this case, the brush limiting part 72 can prevent unnecessary displacement of the brush assembly 6 during the docking process by limiting the brush housing. For example, the brush limiting part 72 may also include the inner wall of the receiving cavity 71. When the brush assembly 6 is pushed in and abuts against the inner wall of the receiving cavity 71, the vacuum cleaner is in the pushed-in position relative to the base station 3.

[0059] See Figures 1 to 2 In one implementation, after the vacuum cleaner reaches the push-in position, the user continues to push the vacuum cleaner main unit 5 towards the base station 3. At this time, the floor brush assembly 6 located in the push-in position is restricted and no longer moves. Under the action of the user's pushing force, the vacuum cleaner main unit 5 continues to move towards the docking part 31 of the base station 3 and docks with the base station 3 through the docking interface 312 of the docking part 31 in a roughly horizontal direction. In order to improve the stability after docking, the docking part 31 of the base station 3 is provided with a main unit limiting structure 313, which is used to limit the vacuum cleaner main unit 5 when it is in the dust collection position after the vacuum cleaner has docked with the base station 3.

[0060] Furthermore, the main unit limiting structure 313 includes a retractable elastic buckle 3131. When the vacuum cleaner is in the process of docking or disassembling, the elastic buckle 3131 can retract and avoid the squeezing of the vacuum cleaner main unit 5. When the vacuum cleaner has completed docking and is in the dust collection position, the elastic buckle 3131 extends to limit the vacuum cleaner main unit 5.

[0061] In one embodiment, the vacuum cleaner main unit 5 is provided with a positioning slot 51 that cooperates with the elastic buckle 3131. When the vacuum cleaner is in the dust collection position relative to the base station 3, the elastic buckle 3131 and the positioning slot 51 cooperate to restrict the movement of the vacuum cleaner main unit 5, making the docking more stable. Specifically, the elastic buckle 3131 can be provided on the end face of the docking part 31, and the positioning slot 51 can be provided on the surface of the vacuum cleaner main unit 5 opposite to the end face, such as the bottom of the dust cup 1.

[0062] In another embodiment, the elastic buckle 3131 is located on the side wall of the docking part 31. In this case, there is no need to set the positioning slot 51 on the vacuum cleaner host 5. After the vacuum cleaner host 5 completes docking with the base station 3, the elastic buckle 3131 can abut against the outer wall of the dust cup 1 to prevent the vacuum cleaner host 5 from coming out of the opening 711. Of course, the elastic buckle 3131 can also be set on the side wall and the end face of the docking part 31 at the same time to optimize the positioning effect and prevent the dust cup 1 dust outlet 111 and the base station 3 dust collection port 311 from gaps or even the vacuum cleaner from separating from the base station 3 due to vibration during the extraction process.

[0063] Furthermore, the interface 312 extends from the horizontal direction to the vertical direction, meaning that when the user uses the push-in method for docking, the user can also use the lifting method to place the vacuum cleaner into the base station 3 from above to dock, increasing the docking options for the user. At this time, the elastic buckle 3131 can be set on the side wall of the docking part 31. The elastic buckle 3131 can be set in a hemispherical shape, so that when the user docks the vacuum cleaner from the vertical direction of the interface 312, the end face of the dust cup 1 is not stuck by the elastic buckle 3131, which would cause interference and prevent docking from being completed.

[0064] See Figure 4 In another embodiment, the host limiting structure 313 includes a first magnetic suction part 3132 disposed on the docking part 31, and the host 5 is provided with a second magnetic suction part 52 for magnetically engaging with the first magnetic suction part 3132. In the dust collection position, the magnetic engagement of the first magnetic suction part 3132 and the second magnetic suction part 52 achieves positioning of the vacuum cleaner host 5, limiting the displacement of the host 5 relative to the base station 3. Furthermore, both the elastic buckle 3131 and the first magnetic suction part 3132 can be simultaneously disposed on the docking part 31, and a corresponding structure can be provided on the host 5. By employing both snap-fit ​​and magnetic attraction methods to position the host 5, the stability of the docking between the vacuum cleaner and the base station 3 can be further optimized.

[0065] In one specific embodiment, the vacuum cleaner includes a main unit 5 and an extension tube 4. The main unit 5 includes a handle 41, a first suction source 42 disposed within the main unit 5, and the aforementioned dust cup 1. The dust cup 1 includes a bottom wall 12 and a peripheral side wall 11 surrounding the bottom wall 12. The peripheral side wall 11 has an openable and closable dust discharge port 111. The base station 3 includes a docking part 31, and the docking part 31 is provided with a dust collection port 311 corresponding to the dust discharge port 111. Of course, in other embodiments, the dust discharge port 111 can be directly opened at the bottom wall 12. Regardless of whether the dust discharge port 111 is located at the peripheral side wall 11 or the bottom wall 12, the aforementioned and subsequent descriptions of the base station 3 can be the same. The docking direction between the vacuum cleaner and the base station 3 is consistent. The position of the dust discharge port 111 does not affect the setting of the base station 3 or the docking direction between the vacuum cleaner and the base station 3, but only affects the setting of the docking part 31.

[0066] The vacuum cleaner includes a floor brush assembly 6 that is pushed into the base station 3 in a generally horizontal direction and a dust collection position where the vacuum cleaner main unit 5 is docked with the docking part 31 in a generally horizontal direction. In the dust collection position, the dust collection port 311 is in fluid communication with the dust discharge port 111.

[0067] Furthermore, the docking part 31 of the base station 3 is capable of being pushed into the vacuum cleaner host 5 in a generally horizontal direction. Specifically, the docking part 31 includes a docking interface 312 that is open in at least a horizontal direction, so that when the user pushes the vacuum cleaner into the base station 3 in a horizontal direction, the vacuum cleaner host 5 can dock with the docking part 31 in a generally horizontal direction through the docking interface 312.

[0068] Furthermore, the axial direction of the dust collection port 311 extends in a generally horizontal direction. When the host 5 is docked with the docking part 31, the dust discharge port 111 approaches the dust collection port 311 in a direction that is generally parallel to the axial direction of the dust collection port 311.

[0069] See Figures 6 to 10 In one embodiment, the dust cup 1 has a cup body and a cup lid 2 pivotally connected to the cup body. The cup body is preferably cylindrical and includes a bottom wall 12 and a peripheral side wall 11 surrounding the bottom wall 12. The dust discharge port 111 is provided on the peripheral side wall 11 near the bottom wall 12. The cup lid 2 includes a normally closed cover plate 21 and a locking assembly.

[0070] The normally closed cover 21 is pivotally connected to the cup body via a rotating shaft 211, and is positioned over the dust outlet in an open state (open) and a closed state (closed). It is adapted to open under external suction, allowing waste inside the cup to be discharged through the dust outlet. The normally closed design of the cup cover prevents dust from overflowing and causing contamination if the locking mechanism is unlocked but the dust collection port and dust outlet are not fully aligned.

[0071] The locking component is used to keep the normally closed cover in a locked state to prevent the normally closed cover from opening automatically and causing garbage to leak out.

[0072] In one embodiment, a torsion spring 212 connects the normally closed cover 21 to the cup body. The torsion spring is sleeved on the rotating shaft 211, so that the dust discharge port of the normally closed cover relative to the cup body is normally closed. When the normally closed cover is opened by an external force, the torsion spring accumulates energy; when the external force is removed, the normally closed cover gradually closes to the dust discharge port under the torsion of the torsion spring. The external force can be the suction force generated by the base station 3, that is, the normally closed cover can be opened under negative pressure.

[0073] In one embodiment, the locking assembly includes a pressure plate 22 and an elastic element, wherein the pressure plate 22 is lowered by the elastic element to press the normally closed cover plate against the cup body.

[0074] The pressure plate 22 is located near the pivot 211 between the normally closed cover and the cup body. The elastic element is preferably a compression spring 23, which is pressed between the cup body and the pressure plate 22. It can be compressed and stored when the pressure plate 22 is moved away from the normally closed cover by force. After the external force on the pressure plate 22 disappears, it releases potential energy to move the pressure plate 22 towards the normally closed cover and press the normally closed cover tightly onto the cup body.

[0075] The dust outlet is located on the peripheral sidewall 11 of the cup body. The main unit of the vacuum cleaner is placed horizontally on the base station 3. The movement direction of the pressure plate 22 is perpendicular to the first direction. The pressure plate 22 slides up and down along the axial direction of the cup body, and the sliding direction of the pressure plate 22 is parallel to the axial direction of the cup body. This optimizes the docking and unlocking structure, making the entire docking process smoother and improving the user experience.

[0076] The movement direction of the pressure plate 22 forms an angle with the extension axis of the vacuum cleaner handle, which is 80°-140°. This optimizes the docking and unlocking structure while ensuring the comfort of the handle, making the entire docking process smoother and improving the user experience.

[0077] The cup body is provided with a sliding space 114, and the pressure plate 22 is embedded in the sliding space 114 and can slide along the sliding space. Preferably, the end of the sliding space away from the rotating shaft 211 is provided with a limiting protrusion 115, which is used to limit the sliding stroke of the pressure plate 22. When the pressure plate 22 slides to the position, it is stopped by the limiting protrusion 115.

[0078] The outer middle of the pressure plate 22 is provided with a pressure plate 2211. The pressure plate 2211 can be pressed by the corresponding unlocking structure on the base station 3 during the installation of the dust cup 1 on the base station 3, so that the pressure plate 22 moves away from the normally closed cover plate 21, thereby releasing the lock on the normally closed cover plate 21 and allowing the normally closed cover plate 21 to be opened under the action of external force.

[0079] In addition, the outer wall of the normally closed cover plate 21 is provided with a clearance groove 213 at a position corresponding to the sliding space. The clearance groove 213 is used to make way for the sliding of the unlocking structure on the base station 3. The pressure plate 22 can be slidably inserted into the clearance groove 213, and then presses against the outer side of the normally closed cover plate 21, pressing the normally closed cover plate 21 tightly against the cup body, thus locking the normally closed cover plate 21.

[0080] The pressure plate 22 has a pressing end 221, which is slidably inserted into the relief groove 213 to press against the side of the normally closed cover plate 21 facing away from the dust outlet. The end of the pressing end 221 has a guide slope to facilitate insertion of the pressing end into the relief groove 213 of the normally closed cover plate 21.

[0081] The end of the pressure plate 22 away from the pressing end is provided with a spring mounting cavity, and one end of the compression spring 23 is installed in the spring mounting cavity.

[0082] The pressure plate 22 has guide blocks on both sides of the end away from the pressing end. The sliding space has a guide groove. The guide blocks are inserted into the guide groove and slide along the guide groove, thereby installing the pressure plate 22 in the sliding space and guiding the pressure plate 22.

[0083] Preferably, the pressure plate 22 does not protrude beyond the outline of the cup body to avoid accidental triggering and leakage of waste from the dust cup 1. The cup body is also provided with a decorative cover 113 and a decorative cover mounting structure 112. The decorative cover 113 is connected to the decorative cover mounting structure 112, for example, by a snap-fit ​​connection, and is mounted on the cup body to conceal the locking component and its sliding space, thus giving the dust cup a better appearance.

[0084] In addition, the decorative cover 113, the normally closed cup cover 21 and the outer contour of the cup body are arranged in a cocircumference when the normally closed cup cover 21 is closed on the dust outlet 111.

[0085] In this invention, the base station 3 is used to dock with at least a portion of the structure of the dust cup 1 of the vacuum cleaner, transferring the dust in the dust cup 1 to the base station 3.

[0086] The base station 3 includes a docking part 31 and a dust collection chamber 34. The dust collection chamber is connected to the dust collection port of the docking part through an airflow channel. The dust collection port of the docking part is connected to the dust discharge port of the dust cup 1 after the dust cup 1 is docked and the normally closed cover plate 21 of the dust cup 1 is opened.

[0087] In one implementation, the base station 3 is further provided with a second suction source, which is used to generate suction airflow in the airflow channel to transfer the garbage in the dust cup 1 to the dust collection chamber 34 through the dust discharge port.

[0088] Correspondingly, the docking part is provided with the unlocking structure at the position corresponding to the pressure plate 22 of the pressure plate 22. This unlocking structure can press against the pressure plate 2211 during the installation of the dust cup 1 on the base station, or after the dust cup is docked with the base station and in the dust collection position, press against the pressure plate 2211 before the base station starts cleaning the dust cup, thereby pushing the pressure plate 22 to slide away from the normally closed cover plate 21, so that the pressure plate 22 is separated from the normally closed cover plate 21, thereby unlocking the normally closed cover plate 21. This allows the normally closed cover plate 21 to open under the action of the suction airflow, and the garbage in the dust cup 1 can be sucked out from the dust outlet into the dust collection chamber by the suction airflow of the second suction source. The movement direction of the pressure plate 22 is parallel to the axis of the second suction source.

[0089] In addition, the dust collection chamber has a clearance space 35, which is used to allow the normally closed cover plate 21 to open, so as to ensure that the normally closed cover plate 21 can be fully opened, thereby ensuring that the garbage in the dust cup 1 is discharged smoothly.

[0090] In both the push-in position and the dust collection position, the floor brush assembly 6 is supported by the base station 3 or by the surface to be cleaned.

[0091] At both the push-in position and the dust collection position, the extension tube 4 is at the same maximum height from the surface to be cleaned in its vertical state. When operating the vacuum cleaner, the user only needs to push the vacuum cleaner to the base station 3 without lifting it. After the floor brush assembly 6 is in place, the user can directly push the main unit 5 towards the base station 3 to achieve docking. Throughout the docking process between the vacuum cleaner and the base station 3, the user only needs to push the vacuum cleaner in a direction away from the body, without lifting it. This convenient operation reduces the steps and effort required for the user to operate the vacuum cleaner, making it more effortless and convenient to use, thus improving the user experience.

[0092] In one embodiment, at the dust collection position, the vacuum cleaner main unit discharges dust from the dust outlet in a generally horizontal direction, and at the dust collection position, the dust collection outlet is in fluid communication with the dust outlet. The vacuum cleaner discharges dust from the side of the dust cup. Compared to bottom dust discharge, side dust discharge reduces the risk of dust leakage from the dust cup when the vacuum cleaner is removed from the base station, avoiding secondary pollution to the environment and improving the user experience.

[0093] Second Embodiment

[0094] The second embodiment shares the same set of drawings as the first embodiment. Since there are only minor differences in the description of the scheme, the description of the structure is directly referred to in the first embodiment.

[0095] See Figures 1 to 5 This utility model provides a cleaning system, including a base station 3 and a vacuum cleaner docked with the base station 3. The vacuum cleaner includes a floor brush assembly 6, a main unit 5 with a dust cup 1, and an extension tube 4 fluidly communicating the floor brush assembly 6 and the dust cup 1. The dust cup 1 includes an openable and closable dust discharge port 111. The base station 3 includes a docking part 31, which has a dust collection port 311 communicating with the dust discharge port 111. The vacuum cleaner has a push-in position where the floor brush assembly 6 is retracted towards the base station 3 in a first direction, and a dust collection position where the vacuum cleaner main unit docks with the docking part 31 in a second direction. In the dust collection position, the dust collection port 311 is fluidly communicating with the dust discharge port 111. The first direction and the second direction are not perpendicular.

[0096] In one embodiment, the first direction and the second direction are generally horizontal or generally parallel to the surface to be cleaned. That is, the floor brush assembly 6 is pushed into the base station 3 in a generally horizontal or generally parallel direction to the surface to be cleaned.

[0097] In one embodiment, the dust collection port 311 is provided corresponding to the dust discharge port 111.

[0098] When the vacuum cleaner is docked to the base station 3, it can collect dust and debris from the dust cup 1. In this vacuum cleaner configuration, one end of the extension tube 4 is connected to the vacuum cleaner main unit 5, and the other end is connected to the floor brush assembly 6. During cleaning, the user holds the vacuum cleaner main unit 5, and part of the weight of the main unit 5 is transferred to the floor brush assembly 6 through the extension tube 4. This allows the vacuum cleaner to be supported on the surface to be cleaned by the floor brush assembly 6. At the same time, the main unit 5 generates suction force, causing the floor brush assembly 6 to suck up the dust and debris from the surface to be cleaned and transport it to the dust cup 1 through the extension tube 4. When it is necessary to clean the debris collected by the vacuum cleaner, or further, when it is necessary to clean the dust and debris in the dust cup 1, the user can move the vacuum cleaner along the surface to be cleaned towards the direction in which the base station 3 is placed. After the vacuum cleaner is pushed into the base station 3 in a roughly horizontal direction with the floor brush assembly 6, the vacuum cleaner is in the pushed-in position relative to the base station 3. At this time, the user continues to push the main unit 5 of the vacuum cleaner towards the docking part 31 of the base station 3, so that the main unit 5 docks with the docking part 31 of the base station 3 in a roughly horizontal direction. After the main unit 5 docks with the docking part 31, the vacuum cleaner is in the dust collection position relative to the base station 3. At this time, the dust discharge port 111 of the dust cup 1 docks with the dust collection port 311 of the base station 3. During the cleaning process of the vacuum cleaner by the base station 3, the dust and debris in the dust cup 1 can be discharged from the dust cup 1 through the dust discharge port 111 and enter the base station 3 through the dust collection port 311 to be collected by the base station 3. With the solution of this utility model, the user does not need to lift the entire vacuum cleaner off the surface to be cleaned during the entire process of moving the vacuum cleaner to the position of the base station 3 until the vacuum cleaner docks with the base station 3. Compared with the existing docking method, it is more labor-saving and optimizes the user experience.

[0099] Furthermore, after the base station 3 has finished cleaning the vacuum cleaner, the user only needs to move the main unit 5 of the vacuum cleaner in the opposite direction to the docking process between the vacuum cleaner and the docking part 31, so that the main unit 5 of the vacuum cleaner is disengaged from the docking part 31, and then continue to move the vacuum cleaner so that the floor brush assembly 6 is disengaged from the base station 3 to complete the separation of the entire vacuum cleaner from the base station 3. Therefore, the user does not need to lift the entire vacuum cleaner during the process of the vacuum cleaner disengaging from the base station 3.

[0100] It should be noted that "pushing the floor brush assembly 6 into the base station 3" here means that the floor brush assembly 6 enters the space formed by the structure of the base station 3 for parking the floor brush assembly 6, that is, the bottom surface of the floor brush assembly 6 is not in contact with the surface to be cleaned at all; it can also mean that the floor brush assembly 6 enters the area enclosed by the base station 3 on the surface to be cleaned, that is, the bottom surface of the floor brush assembly 6 is still in contact with the surface to be cleaned; of course, it can also mean that part of the floor brush assembly 6 enters the space formed by the structure of the base station 3 for parking the floor brush assembly 6, and part of it is located in the area enclosed by the base station 3 on the surface to be cleaned, that is, at least part of the bottom surface of the floor brush assembly 6 is not in contact with the surface to be cleaned. Specifically, the base station 3 includes a receiving cavity 71 into which the floor brush assembly 6 is pushed in a generally horizontal direction. At the pushed-in position, the floor brush assembly 6 is at least partially located in the receiving cavity 71. For example, in order to ensure the integrity of the shape of the vacuum cleaner docked on the base station 3, it is better to accommodate the floor brush assembly 6 entirely in the receiving cavity 71 at the bottom of the base station 3. On the other hand, in order to ensure the smooth airflow when the base station 3 cleans the vacuum cleaner, it is possible to consider exposing the position of the floor brush assembly 6 with the suction port outside the receiving cavity 71 of the base station 3.

[0101] See Figures 4 to 5 In one embodiment, the base station 3 includes a base 7 and a docking part 31 with a docking interface 312. The base 7 has a receiving cavity 71. The opening 711 of the receiving cavity 71 and the docking interface 312 of the docking part 31 face the same side in the horizontal direction. With this configuration, the user can push the floor brush assembly 6 and the main unit 5 of the vacuum cleaner into and dock them with the base station 3 in the same direction. The operation is simple and there is no need to adjust the direction of the main unit 5 relative to the base station 3 during the docking process. At the same time, it can avoid interference between the vacuum cleaner and the base station 3 during docking.

[0102] Furthermore, the base 7 is provided with a floor brush limiting part 72, which is used to limit the displacement of the floor brush assembly 6 relative to the base station 3, so as to prevent the floor brush assembly 6 from moving relative to the base station 3 during the process of the vacuum cleaner moving from the push-in position to the dust collection position and docking with the base station 3, causing the floor brush assembly 6 to detach from the base station 3 again when the host 5 docks with the docking part 31, thus affecting the docking effect.

[0103] In one embodiment, the base 7 includes a guide portion and a floor brush limiting portion 72. The guide portion can guide the floor brush assembly 6 from the surface to be cleaned into the receiving cavity 71 of the base 7 in a generally horizontal direction. The limiting portion on the base 7 can limit the position of the floor brush assembly 6 after it is pushed into the receiving cavity 71.

[0104] Specifically, the guide section includes a guide base plate 73 located at the opening 711 of the receiving cavity 71. The guide base plate 73 guides the movement direction of the floor brush assembly 6 when the user pushes the vacuum cleaner towards the base station 3, thereby limiting the docking direction of the vacuum cleaner relative to the base station 3, making the docking more accurate and less prone to deviation. The floor brush limiting section 72 includes a groove 721 provided on the guide base plate 73. The floor brush assembly 6 includes an auxiliary wheel 61. When the floor brush assembly 6 enters the receiving cavity 71 of the base 7 from the cleaning surface through the guide base plate 73, the auxiliary wheel 61 falls into the groove 721 to achieve limiting, at which time the vacuum cleaner is in the pushed-in position relative to the base station 3.

[0105] In another embodiment, the brush limiting part 72 is disposed within the receiving cavity 71. In this case, the brush limiting part 72 can prevent unnecessary displacement of the brush assembly 6 during the docking process by limiting the brush housing. For example, the brush limiting part 72 may also include the inner wall of the receiving cavity 71. When the brush assembly 6 is pushed in and abuts against the inner wall of the receiving cavity 71, the vacuum cleaner is in the pushed-in position relative to the base station 3.

[0106] See Figures 1 to 2 In one implementation, after the vacuum cleaner reaches the push-in position, the user continues to push the vacuum cleaner main unit 5 towards the base station 3. At this time, the floor brush assembly 6 located in the push-in position is restricted and no longer moves. Under the action of the user's pushing force, the vacuum cleaner main unit 5 continues to move towards the docking part 31 of the base station 3 and docks with the base station 3 through the docking interface 312 of the docking part 31 in a roughly horizontal direction. In order to improve the stability after docking, the docking part 31 of the base station 3 is provided with a main unit limiting structure 313, which is used to limit the vacuum cleaner main unit 5 when it is in the dust collection position after the vacuum cleaner has docked with the base station 3.

[0107] Furthermore, the main unit limiting structure 313 includes a retractable elastic buckle 3131. When the vacuum cleaner is in the process of docking or disassembling, the elastic buckle 3131 can retract and avoid the squeezing of the vacuum cleaner main unit 5. When the vacuum cleaner has completed docking and is in the dust collection position, the elastic buckle 3131 extends to limit the vacuum cleaner main unit 5.

[0108] In one embodiment, the vacuum cleaner main unit 5 is provided with a positioning slot 51 that cooperates with the elastic buckle 3131. When the vacuum cleaner is in the dust collection position relative to the base station 3, the elastic buckle 3131 and the positioning slot 51 cooperate to restrict the movement of the vacuum cleaner main unit 5, making the docking more stable. Specifically, the elastic buckle 3131 can be provided on the end face of the docking part 31, and the positioning slot 51 can be provided on the surface of the vacuum cleaner main unit 5 opposite to the end face, such as the bottom of the dust cup 1.

[0109] In another embodiment, the elastic buckle 3131 is located on the side wall of the docking part 31. In this case, there is no need to set the positioning slot 51 on the vacuum cleaner host 5. After the vacuum cleaner host 5 completes docking with the base station 3, the elastic buckle 3131 can abut against the outer wall of the dust cup 1 to prevent the vacuum cleaner host 5 from coming out of the opening 711. Of course, the elastic buckle 3131 can also be set on the side wall and the end face of the docking part 31 at the same time to optimize the positioning effect and prevent the dust cup 1 dust outlet 111 and the base station 3 dust collection port 311 from gaps or even the vacuum cleaner from separating from the base station 3 due to vibration during the extraction process.

[0110] Furthermore, the interface 312 extends from the horizontal direction to the vertical direction, meaning that when the user uses the push-in method for docking, the user can also use the lifting method to place the vacuum cleaner into the base station 3 from above to dock, increasing the docking options for the user. At this time, the elastic buckle 3131 can be set on the side wall of the docking part 31. The elastic buckle 3131 can be set in a hemispherical shape, so that when the user docks the vacuum cleaner from the vertical direction of the interface 312, the end face of the dust cup 1 is not stuck by the elastic buckle 3131, which would cause interference and prevent docking from being completed.

[0111] See Figure 4 In another embodiment, the host limiting structure 313 includes a first magnetic suction part 3132 disposed on the docking part 31, and the host 5 is provided with a second magnetic suction part 52 for magnetically engaging with the first magnetic suction part 3132. In the dust collection position, the magnetic engagement of the first magnetic suction part 3132 and the second magnetic suction part 52 achieves positioning of the vacuum cleaner host 5, limiting the displacement of the host 5 relative to the base station 3. Furthermore, both the elastic buckle 3131 and the first magnetic suction part 3132 can be simultaneously disposed on the docking part 31, and a corresponding structure can be provided on the host 5. By employing both snap-fit ​​and magnetic attraction methods to position the host 5, the stability of the docking between the vacuum cleaner and the base station 3 can be further optimized.

[0112] In one specific embodiment, the vacuum cleaner includes a main unit 5 and an extension tube 4. The main unit 5 includes a handle 41, a first suction source 42 disposed within the main unit 5, and the aforementioned dust cup 1. The dust cup 1 includes a bottom wall 12 and a peripheral side wall 11 surrounding the bottom wall 12. The peripheral side wall 11 has an openable and closable dust discharge port 111. The base station 3 includes a docking part 31, and the docking part 31 is provided with a dust collection port 311 corresponding to the dust discharge port 111. Of course, in other embodiments, the dust discharge port 111 can be directly opened at the bottom wall 12. Regardless of whether the dust discharge port 111 is located at the peripheral side wall 11 or the bottom wall 12, the aforementioned and subsequent descriptions of the base station 3 can be the same. The docking direction between the vacuum cleaner and the base station 3 is consistent. The position of the dust discharge port 111 does not affect the setting of the base station 3 or the docking direction between the vacuum cleaner and the base station 3, but only affects the setting of the docking part 31.

[0113] The vacuum cleaner includes a floor brush assembly 6 that is pushed into the base station 3 in a generally horizontal direction and a dust collection position where the vacuum cleaner main unit 5 is docked with the docking part 31 in a generally horizontal direction. In the dust collection position, the dust collection port 311 is in fluid communication with the dust discharge port 111.

[0114] Furthermore, the docking part 31 of the base station 3 is capable of being pushed into the vacuum cleaner host 5 in a generally horizontal direction. Specifically, the docking part 31 includes a docking interface 312 that is open in at least a horizontal direction, so that when the user pushes the vacuum cleaner into the base station 3 in a horizontal direction, the vacuum cleaner host 5 can dock with the docking part 31 in a generally horizontal direction through the docking interface 312.

[0115] Furthermore, the axial direction of the dust collection port 311 extends in a generally horizontal direction. When the host 5 is docked with the docking part 31, the dust discharge port 111 approaches the dust collection port 311 in a direction that is generally parallel to the axial direction of the dust collection port 311.

[0116] See Figures 6 to 10 In one embodiment, the dust cup 1 has a cup body and a cup lid 2 pivotally connected to the cup body. The cup body is preferably cylindrical and includes a bottom wall 12 and a peripheral side wall 11 surrounding the bottom wall 12. The dust discharge port 111 is provided on the peripheral side wall 11 near the bottom wall 12. The cup lid 2 includes a normally closed cover plate 21 and a locking assembly.

[0117] The normally closed cover 21 is pivotally connected to the cup body via a rotating shaft 211, and is positioned over the dust outlet in an open state (open) and a closed state (closed). It is adapted to open under external suction, allowing waste inside the cup to be discharged through the dust outlet. The normally closed design of the cup cover prevents dust from overflowing and causing contamination if the locking mechanism is unlocked but the dust collection port and dust outlet are not fully aligned.

[0118] The locking component is used to keep the normally closed cover in a locked state to prevent the normally closed cover from opening automatically and causing garbage to leak out.

[0119] In one embodiment, a torsion spring 212 connects the normally closed cover 21 to the cup body. The torsion spring is sleeved on the rotating shaft 211, so that the dust discharge port of the normally closed cover relative to the cup body is normally closed. When the normally closed cover is opened by an external force, the torsion spring accumulates energy; when the external force is removed, the normally closed cover gradually closes to the dust discharge port under the torsion of the torsion spring. The external force can be the suction force generated by the base station 3, that is, the normally closed cover can be opened under negative pressure.

[0120] In one embodiment, the locking assembly includes a pressure plate 22 and an elastic element, wherein the pressure plate 22 is lowered by the elastic element to press the normally closed cover plate against the cup body.

[0121] The pressure plate 22 is located near the pivot 211 between the normally closed cover and the cup body. The elastic element is preferably a compression spring 23, which is pressed between the cup body and the pressure plate 22. It can be compressed and stored when the pressure plate 22 is moved away from the normally closed cover by force. After the external force on the pressure plate 22 disappears, it releases potential energy to move the pressure plate 22 towards the normally closed cover and press the normally closed cover tightly onto the cup body.

[0122] The dust outlet is located on the peripheral sidewall 11 of the cup body. The main unit of the vacuum cleaner is placed horizontally on the base station 3. The movement direction of the pressure plate 22 is perpendicular to the first direction. The pressure plate 22 slides up and down along the axial direction of the cup body, and the sliding direction of the pressure plate 22 is parallel to the axial direction of the cup body. This optimizes the docking and unlocking structure, making the entire docking process smoother and improving the user experience.

[0123] The movement direction of the pressure plate 22 forms an angle with the extension axis of the vacuum cleaner handle, which is 80°-140°. This optimizes the docking and unlocking structure while ensuring the comfort of the handle, making the entire docking process smoother and improving the user experience.

[0124] The cup body is provided with a sliding space 114, and the pressure plate 22 is embedded in the sliding space 114 and can slide along the sliding space. Preferably, the end of the sliding space away from the rotating shaft 211 is provided with a limiting protrusion 115, which is used to limit the sliding stroke of the pressure plate 22. When the pressure plate 22 slides to the position, it is stopped by the limiting protrusion 115.

[0125] The outer middle of the pressure plate 22 is provided with a pressure plate 2211. The pressure plate 2211 can be pressed by the corresponding unlocking structure on the base station 3 during the installation of the dust cup 1 on the base station 3, so that the pressure plate 22 moves away from the normally closed cover plate 21, thereby releasing the lock on the normally closed cover plate 21 and allowing the normally closed cover plate 21 to be opened under the action of external force.

[0126] In addition, the outer wall of the normally closed cover plate 21 is provided with a clearance groove 213 at a position corresponding to the sliding space. The clearance groove 213 is used to make way for the sliding of the unlocking structure on the base station 3. The pressure plate 22 can be slidably inserted into the clearance groove 213, and then presses against the outer side of the normally closed cover plate 21, pressing the normally closed cover plate 21 tightly against the cup body, thus locking the normally closed cover plate 21.

[0127] The pressure plate 22 has a pressing end 221, which is slidably inserted into the relief groove 213 to press against the side of the normally closed cover plate 21 facing away from the dust outlet. The end of the pressing end 221 has a guide slope to facilitate insertion of the pressing end into the relief groove 213 of the normally closed cover plate 21.

[0128] The end of the pressure plate 22 away from the pressing end is provided with a spring mounting cavity, and one end of the compression spring 23 is installed in the spring mounting cavity.

[0129] The pressure plate 22 has guide blocks on both sides of the end away from the pressing end. The sliding space has a guide groove. The guide blocks are inserted into the guide groove and slide along the guide groove, thereby installing the pressure plate 22 in the sliding space and guiding the pressure plate 22.

[0130] Preferably, the pressure plate 22 does not protrude beyond the outline of the cup body to avoid accidental triggering and leakage of waste from the dust cup 1. The cup body is also provided with a decorative cover 113 and a decorative cover mounting structure 112. The decorative cover 113 is connected to the decorative cover mounting structure 112, for example, by a snap-fit ​​connection, and is mounted on the cup body to conceal the locking component and its sliding space, thus giving the dust cup a better appearance.

[0131] In addition, the decorative cover 113, the normally closed cup cover 21 and the outer contour of the cup body are arranged in a cocircumference when the normally closed cup cover 21 is closed on the dust outlet 111.

[0132] In this invention, the base station 3 is used to dock with at least a portion of the structure of the dust cup 1 of the vacuum cleaner, transferring the dust in the dust cup 1 to the base station 3.

[0133] The base station 3 includes a docking part 31 and a dust collection chamber 34. The dust collection chamber is connected to the dust collection port of the docking part through an airflow channel. The dust collection port of the docking part is connected to the dust discharge port of the dust cup 1 after the dust cup 1 is docked and the normally closed cover plate 21 of the dust cup 1 is opened.

[0134] In one implementation, the base station 3 is further provided with a second suction source, which is used to generate suction airflow in the airflow channel to transfer the garbage in the dust cup 1 to the dust collection chamber 34 through the dust discharge port.

[0135] Correspondingly, the docking part is provided with the unlocking structure at the position corresponding to the pressure plate 22 of the pressure plate 22. This unlocking structure can press against the pressure plate 2211 during the installation of the dust cup 1 on the base station, or after the dust cup is docked with the base station and in the dust collection position, press against the pressure plate 2211 before the base station starts cleaning the dust cup, thereby pushing the pressure plate 22 to slide away from the normally closed cover plate 21, so that the pressure plate 22 is separated from the normally closed cover plate 21, thereby unlocking the normally closed cover plate 21. This allows the normally closed cover plate 21 to open under the action of the suction airflow, and the garbage in the dust cup 1 can be sucked out from the dust outlet into the dust collection chamber by the suction airflow of the second suction source. The movement direction of the pressure plate 22 is parallel to the axis of the second suction source.

[0136] In addition, the dust collection chamber has a clearance space 35, which is used to allow the normally closed cover plate 21 to open, so as to ensure that the normally closed cover plate 21 can be fully opened, thereby ensuring that the garbage in the dust cup 1 is discharged smoothly.

[0137] In both the push-in position and the dust collection position, the floor brush assembly 6 is supported by the base station 3 or by the surface to be cleaned.

[0138] At both the push-in position and the dust collection position, the extension tube 4 is at the same maximum height from the surface to be cleaned in its vertical state. When operating the vacuum cleaner, the user only needs to push the vacuum cleaner to the base station 3 without lifting it. After the floor brush assembly 6 is in place, the user can directly push the main unit 5 towards the base station 3 to achieve docking. Throughout the docking process between the vacuum cleaner and the base station 3, the user only needs to push the vacuum cleaner in a direction away from the body, without lifting it. This convenient operation reduces the steps and effort required for the user to operate the vacuum cleaner, making it more effortless and convenient to use, thus improving the user experience.

[0139] In one embodiment, at the dust collection position, the vacuum cleaner main unit discharges dust from the dust outlet in a generally horizontal direction, and at the dust collection position, the dust collection outlet is in fluid communication with the dust outlet. The vacuum cleaner discharges dust from the side of the dust cup. Compared to bottom dust discharge, side dust discharge reduces the risk of dust leakage from the dust cup when the vacuum cleaner is removed from the base station, avoiding secondary pollution to the environment and improving the user experience.

[0140] In one embodiment, at the dust collection position, the vacuum cleaner main unit discharges dust from the dust outlet along a third direction, the dust collection outlet and the dust outlet are in fluid communication, and the first direction is not perpendicular to the third direction. In a further embodiment, the first direction is substantially parallel to the third direction, or the second direction is substantially parallel to the third direction.

[0141] Third Embodiment

[0142] The third embodiment shares the same set of drawings as the first embodiment. Since there are only minor differences in the description of the scheme, the description of the structure is directly referred to in the first embodiment.

[0143] See Figures 1 to 5 This utility model provides a cleaning system, including a base station 3 and a vacuum cleaner docked with the base station 3. The vacuum cleaner includes a floor brush assembly 6, a main unit 5 with a dust cup 1, and an extension tube 4 fluidly communicating the floor brush assembly 6 and the dust cup 1. The dust cup 1 includes an openable and closable dust discharge port 111. The base station 3 includes a docking part 31, which has a dust collection port 311 communicating with the dust discharge port 111. The vacuum cleaner has a push-in position where the floor brush assembly 6 is retracted towards the base station 3 in a first direction, and a dust collection position where the vacuum cleaner main unit discharges dust from the dust discharge port 111 in a third direction. In the dust collection position, the dust collection port 311 is fluidly communicating with the dust discharge port 111, and the first direction is not perpendicular to the third direction.

[0144] In one embodiment, the first direction and the third direction are generally horizontal or generally parallel to the surface to be cleaned.

[0145] In a further embodiment, the dust collection port 311 is provided corresponding to the dust discharge port 111. In the pushed-in position, the floor brush assembly 6 is pushed into the base station 3 in a generally horizontal direction. In the dust collection position, the vacuum cleaner main unit 5 docks with the docking part 31 in a generally horizontal direction.

[0146] In one embodiment, at the dust collection location, the vacuum cleaner main unit docks with the docking portion 31 along a second direction, wherein the first and second directions are not perpendicular. In a further embodiment, the first and second directions are approximately horizontal or approximately parallel to the surface to be cleaned. In a further embodiment, the third direction is substantially parallel to the second direction, or both directions are approximately horizontal or both directions are approximately parallel to the surface to be cleaned.

[0147] When the vacuum cleaner is docked to the base station 3, it can collect dust and debris from the dust cup 1. In this vacuum cleaner configuration, one end of the extension tube 4 is connected to the vacuum cleaner main unit 5, and the other end is connected to the floor brush assembly 6. During cleaning, the user holds the vacuum cleaner main unit 5, and part of the weight of the main unit 5 is transferred to the floor brush assembly 6 through the extension tube 4. This allows the vacuum cleaner to be supported on the surface to be cleaned by the floor brush assembly 6. At the same time, the main unit 5 generates suction force, causing the floor brush assembly 6 to suck up the dust and debris from the surface to be cleaned and transport it to the dust cup 1 through the extension tube 4. When it is necessary to clean the debris collected by the vacuum cleaner, or further, when it is necessary to clean the dust and debris in the dust cup 1, the user can move the vacuum cleaner along the surface to be cleaned towards the direction in which the base station 3 is placed. After the vacuum cleaner is pushed into the base station 3 in a roughly horizontal direction with the floor brush assembly 6, the vacuum cleaner is in the pushed-in position relative to the base station 3. At this time, the user continues to push the main unit 5 of the vacuum cleaner towards the docking part 31 of the base station 3, so that the main unit 5 docks with the docking part 31 of the base station 3 in a roughly horizontal direction. After the main unit 5 docks with the docking part 31, the vacuum cleaner is in the dust collection position relative to the base station 3. At this time, the dust discharge port 111 of the dust cup 1 docks with the dust collection port 311 of the base station 3. During the cleaning process of the vacuum cleaner by the base station 3, the dust and debris in the dust cup 1 can be discharged from the dust cup 1 through the dust discharge port 111 and enter the base station 3 through the dust collection port 311 to be collected by the base station 3. With the solution of this utility model, the user does not need to lift the entire vacuum cleaner off the surface to be cleaned during the entire process of moving the vacuum cleaner to the position of the base station 3 until the vacuum cleaner docks with the base station 3. Compared with the existing docking method, it is more labor-saving and optimizes the user experience.

[0148] Furthermore, after the base station 3 has finished cleaning the vacuum cleaner, the user only needs to move the main unit 5 of the vacuum cleaner in the opposite direction to the docking process between the vacuum cleaner and the docking part 31, so that the main unit 5 of the vacuum cleaner is disengaged from the docking part 31, and then continue to move the vacuum cleaner so that the floor brush assembly 6 is disengaged from the base station 3 to complete the separation of the entire vacuum cleaner from the base station 3. Therefore, the user does not need to lift the entire vacuum cleaner during the process of the vacuum cleaner disengaging from the base station 3.

[0149] It should be noted that "pushing the floor brush assembly 6 into the base station 3" here means that the floor brush assembly 6 enters the space formed by the structure of the base station 3 for parking the floor brush assembly 6, that is, the bottom surface of the floor brush assembly 6 is not in contact with the surface to be cleaned at all; it can also mean that the floor brush assembly 6 enters the area enclosed by the base station 3 on the surface to be cleaned, that is, the bottom surface of the floor brush assembly 6 is still in contact with the surface to be cleaned; of course, it can also mean that part of the floor brush assembly 6 enters the space formed by the structure of the base station 3 for parking the floor brush assembly 6, and part of it is located in the area enclosed by the base station 3 on the surface to be cleaned, that is, at least part of the bottom surface of the floor brush assembly 6 is not in contact with the surface to be cleaned. Specifically, the base station 3 includes a receiving cavity 71 into which the floor brush assembly 6 is pushed in a generally horizontal direction. At the pushed-in position, the floor brush assembly 6 is at least partially located in the receiving cavity 71. For example, in order to ensure the integrity of the shape of the vacuum cleaner docked on the base station 3, it is better to accommodate the floor brush assembly 6 entirely in the receiving cavity 71 at the bottom of the base station 3. On the other hand, in order to ensure the smooth airflow when the base station 3 cleans the vacuum cleaner, it is possible to consider exposing the position of the floor brush assembly 6 with the suction port outside the receiving cavity 71 of the base station 3.

[0150] See Figures 4 to 5 In one embodiment, the base station 3 includes a base 7 and a docking part 31 with a docking interface 312. The base 7 has a receiving cavity 71. The opening 711 of the receiving cavity 71 and the docking interface 312 of the docking part 31 face the same side in the horizontal direction. With this configuration, the user can push the floor brush assembly 6 and the main unit 5 of the vacuum cleaner into and dock them with the base station 3 in the same direction. The operation is simple and there is no need to adjust the direction of the main unit 5 relative to the base station 3 during the docking process. At the same time, it can avoid interference between the vacuum cleaner and the base station 3 during docking.

[0151] Furthermore, the base 7 is provided with a floor brush limiting part 72, which is used to limit the displacement of the floor brush assembly 6 relative to the base station 3, so as to prevent the floor brush assembly 6 from moving relative to the base station 3 during the process of the vacuum cleaner moving from the push-in position to the dust collection position and docking with the base station 3, causing the floor brush assembly 6 to detach from the base station 3 again when the host 5 docks with the docking part 31, thus affecting the docking effect.

[0152] In one embodiment, the base 7 includes a guide portion and a floor brush limiting portion 72. The guide portion can guide the floor brush assembly 6 from the surface to be cleaned into the receiving cavity 71 of the base 7 in a generally horizontal direction. The limiting portion on the base 7 can limit the position of the floor brush assembly 6 after it is pushed into the receiving cavity 71.

[0153] Specifically, the guide section includes a guide base plate 73 located at the opening 711 of the receiving cavity 71. The guide base plate 73 guides the movement direction of the floor brush assembly 6 when the user pushes the vacuum cleaner towards the base station 3, thereby limiting the docking direction of the vacuum cleaner relative to the base station 3, making the docking more accurate and less prone to deviation. The floor brush limiting section 72 includes a groove 721 provided on the guide base plate 73. The floor brush assembly 6 includes an auxiliary wheel 61. When the floor brush assembly 6 enters the receiving cavity 71 of the base 7 from the cleaning surface through the guide base plate 73, the auxiliary wheel 61 falls into the groove 721 to achieve limiting, at which time the vacuum cleaner is in the pushed-in position relative to the base station 3.

[0154] In another embodiment, the brush limiting part 72 is disposed within the receiving cavity 71. In this case, the brush limiting part 72 can prevent unnecessary displacement of the brush assembly 6 during the docking process by limiting the brush housing. For example, the brush limiting part 72 may also include the inner wall of the receiving cavity 71. When the brush assembly 6 is pushed in and abuts against the inner wall of the receiving cavity 71, the vacuum cleaner is in the pushed-in position relative to the base station 3.

[0155] See Figures 1 to 2 In one implementation, after the vacuum cleaner reaches the push-in position, the user continues to push the vacuum cleaner main unit 5 towards the base station 3. At this time, the floor brush assembly 6 located in the push-in position is restricted and no longer moves. Under the action of the user's pushing force, the vacuum cleaner main unit 5 continues to move towards the docking part 31 of the base station 3 and docks with the base station 3 through the docking interface 312 of the docking part 31 in a roughly horizontal direction. In order to improve the stability after docking, the docking part 31 of the base station 3 is provided with a main unit limiting structure 313, which is used to limit the vacuum cleaner main unit 5 when it is in the dust collection position after the vacuum cleaner has docked with the base station 3.

[0156] Furthermore, the main unit limiting structure 313 includes a retractable elastic buckle 3131. When the vacuum cleaner is in the process of docking or disassembling, the elastic buckle 3131 can retract and avoid the squeezing of the vacuum cleaner main unit 5. When the vacuum cleaner has completed docking and is in the dust collection position, the elastic buckle 3131 extends to limit the vacuum cleaner main unit 5.

[0157] In one embodiment, the vacuum cleaner main unit 5 is provided with a positioning slot 51 that cooperates with the elastic buckle 3131. When the vacuum cleaner is in the dust collection position relative to the base station 3, the elastic buckle 3131 and the positioning slot 51 cooperate to restrict the movement of the vacuum cleaner main unit 5, making the docking more stable. Specifically, the elastic buckle 3131 can be provided on the end face of the docking part 31, and the positioning slot 51 can be provided on the surface of the vacuum cleaner main unit 5 opposite to the end face, such as the bottom of the dust cup 1.

[0158] In another embodiment, the elastic buckle 3131 is located on the side wall of the docking part 31. In this case, there is no need to set the positioning slot 51 on the vacuum cleaner host 5. After the vacuum cleaner host 5 completes docking with the base station 3, the elastic buckle 3131 can abut against the outer wall of the dust cup 1 to prevent the vacuum cleaner host 5 from coming out of the opening 711. Of course, the elastic buckle 3131 can also be set on the side wall and the end face of the docking part 31 at the same time to optimize the positioning effect and prevent the dust cup 1 dust outlet 111 and the base station 3 dust collection port 311 from gaps or even the vacuum cleaner from separating from the base station 3 due to vibration during the extraction process.

[0159] Furthermore, the interface 312 extends from the horizontal direction to the vertical direction, meaning that when the user uses the push-in method for docking, the user can also use the lifting method to place the vacuum cleaner into the base station 3 from above to dock, increasing the docking options for the user. At this time, the elastic buckle 3131 can be set on the side wall of the docking part 31. The elastic buckle 3131 can be set in a hemispherical shape, so that when the user docks the vacuum cleaner from the vertical direction of the interface 312, the end face of the dust cup 1 is not stuck by the elastic buckle 3131, which would cause interference and prevent docking from being completed.

[0160] See Figure 4 In another embodiment, the host limiting structure 313 includes a first magnetic suction part 3132 disposed on the docking part 31, and the host 5 is provided with a second magnetic suction part 52 for magnetically engaging with the first magnetic suction part 3132. In the dust collection position, the magnetic engagement of the first magnetic suction part 3132 and the second magnetic suction part 52 achieves positioning of the vacuum cleaner host 5, limiting the displacement of the host 5 relative to the base station 3. Furthermore, both the elastic buckle 3131 and the first magnetic suction part 3132 can be simultaneously disposed on the docking part 31, and a corresponding structure can be provided on the host 5. By employing both snap-fit ​​and magnetic attraction methods to position the host 5, the stability of the docking between the vacuum cleaner and the base station 3 can be further optimized.

[0161] In one specific embodiment, the vacuum cleaner includes a main unit 5 and an extension tube 4. The main unit 5 includes a handle 41, a first suction source 42 disposed within the main unit 5, and the aforementioned dust cup 1. The dust cup 1 includes a bottom wall 12 and a peripheral side wall 11 surrounding the bottom wall 12. The peripheral side wall 11 has an openable and closable dust discharge port 111. The base station 3 includes a docking part 31, and the docking part 31 is provided with a dust collection port 311 corresponding to the dust discharge port 111. Of course, in other embodiments, the dust discharge port 111 can be directly opened at the bottom wall 12. Regardless of whether the dust discharge port 111 is located at the peripheral side wall 11 or the bottom wall 12, the aforementioned and subsequent descriptions of the base station 3 can be the same. The docking direction between the vacuum cleaner and the base station 3 is consistent. The position of the dust discharge port 111 does not affect the setting of the base station 3 or the docking direction between the vacuum cleaner and the base station 3, but only affects the setting of the docking part 31.

[0162] The vacuum cleaner includes a floor brush assembly 6 that is pushed into the base station 3 in a generally horizontal direction and a dust collection position where the vacuum cleaner main unit 5 is docked with the docking part 31 in a generally horizontal direction. In the dust collection position, the dust collection port 311 is in fluid communication with the dust discharge port 111.

[0163] Furthermore, the docking part 31 of the base station 3 is capable of being pushed into the vacuum cleaner host 5 in a generally horizontal direction. Specifically, the docking part 31 includes a docking interface 312 that is open in at least a horizontal direction, so that when the user pushes the vacuum cleaner into the base station 3 in a horizontal direction, the vacuum cleaner host 5 can dock with the docking part 31 in a generally horizontal direction through the docking interface 312.

[0164] Furthermore, the axial direction of the dust collection port 311 extends in a generally horizontal direction. When the host 5 is docked with the docking part 31, the dust discharge port 111 approaches the dust collection port 311 in a direction that is generally parallel to the axial direction of the dust collection port 311.

[0165] See Figures 6 to 10 In one embodiment, the dust cup 1 has a cup body and a cup lid 2 pivotally connected to the cup body. The cup body is preferably cylindrical and includes a bottom wall 12 and a peripheral side wall 11 surrounding the bottom wall 12. The dust discharge port 111 is provided on the peripheral side wall 11 near the bottom wall 12. The cup lid 2 includes a normally closed cover plate 21 and a locking assembly.

[0166] The normally closed cover 21 is pivotally connected to the cup body via a rotating shaft 211, and is positioned over the dust outlet in an open state (open) and a closed state (closed). It is adapted to open under external suction, allowing waste inside the cup to be discharged through the dust outlet. The normally closed design of the cup cover prevents dust from overflowing and causing contamination if the locking mechanism is unlocked but the dust collection port and dust outlet are not fully aligned.

[0167] The locking component is used to keep the normally closed cover in a locked state to prevent the normally closed cover from opening automatically and causing garbage to leak out.

[0168] In one embodiment, a torsion spring 212 connects the normally closed cover 21 to the cup body. The torsion spring is sleeved on the rotating shaft 211, so that the dust discharge port of the normally closed cover relative to the cup body is normally closed. When the normally closed cover is opened by an external force, the torsion spring accumulates energy; when the external force is removed, the normally closed cover gradually closes to the dust discharge port under the torsion of the torsion spring. The external force can be the suction force generated by the base station 3, that is, the normally closed cover can be opened under negative pressure.

[0169] In one embodiment, the locking assembly includes a pressure plate 22 and an elastic element, wherein the pressure plate 22 is lowered by the elastic element to press the normally closed cover plate against the cup body.

[0170] The pressure plate 22 is located near the pivot 211 between the normally closed cover and the cup body. The elastic element is preferably a compression spring 23, which is pressed between the cup body and the pressure plate 22. It can be compressed and stored when the pressure plate 22 is moved away from the normally closed cover by force. After the external force on the pressure plate 22 disappears, it releases potential energy to move the pressure plate 22 towards the normally closed cover and press the normally closed cover tightly onto the cup body.

[0171] The dust outlet is located on the peripheral sidewall 11 of the cup body. The main unit of the vacuum cleaner is placed horizontally on the base station 3. The movement direction of the pressure plate 22 is perpendicular to the first direction. The pressure plate 22 slides up and down along the axial direction of the cup body, and the sliding direction of the pressure plate 22 is parallel to the axial direction of the cup body. This optimizes the docking and unlocking structure, making the entire docking process smoother and improving the user experience.

[0172] The movement direction of the pressure plate 22 forms an angle with the extension axis of the vacuum cleaner handle, which is 80°-140°. This optimizes the docking and unlocking structure while ensuring the comfort of the handle, making the entire docking process smoother and improving the user experience.

[0173] The cup body is provided with a sliding space 114, and the pressure plate 22 is embedded in the sliding space 114 and can slide along the sliding space. Preferably, the end of the sliding space away from the rotating shaft 211 is provided with a limiting protrusion 115, which is used to limit the sliding stroke of the pressure plate 22. When the pressure plate 22 slides to the position, it is stopped by the limiting protrusion 115.

[0174] The outer middle of the pressure plate 22 is provided with a pressure plate 2211. The pressure plate 2211 can be pressed by the corresponding unlocking structure on the base station 3 during the installation of the dust cup 1 on the base station 3, so that the pressure plate 22 moves away from the normally closed cover plate 21, thereby releasing the lock on the normally closed cover plate 21 and allowing the normally closed cover plate 21 to be opened under the action of external force.

[0175] In addition, the outer wall of the normally closed cover plate 21 is provided with a clearance groove 213 at a position corresponding to the sliding space. The clearance groove 213 is used to make way for the sliding of the unlocking structure on the base station 3. The pressure plate 22 can be slidably inserted into the clearance groove 213, and then presses against the outer side of the normally closed cover plate 21, pressing the normally closed cover plate 21 tightly against the cup body, thus locking the normally closed cover plate 21.

[0176] The pressure plate 22 has a pressing end 221, which is slidably inserted into the relief groove 213 to press against the side of the normally closed cover plate 21 facing away from the dust outlet. The end of the pressing end 221 has a guide slope to facilitate insertion of the pressing end into the relief groove 213 of the normally closed cover plate 21.

[0177] The end of the pressure plate 22 away from the pressing end is provided with a spring mounting cavity, and one end of the compression spring 23 is installed in the spring mounting cavity.

[0178] The pressure plate 22 has guide blocks on both sides of the end away from the pressing end. The sliding space has a guide groove. The guide blocks are inserted into the guide groove and slide along the guide groove, thereby installing the pressure plate 22 in the sliding space and guiding the pressure plate 22.

[0179] Preferably, the pressure plate 22 does not protrude beyond the outline of the cup body to avoid accidental triggering and leakage of waste from the dust cup 1. The cup body is also provided with a decorative cover 113 and a decorative cover mounting structure 112. The decorative cover 113 is connected to the decorative cover mounting structure 112, for example, by a snap-fit ​​connection, and is mounted on the cup body to conceal the locking component and its sliding space, thus giving the dust cup a better appearance.

[0180] In addition, the decorative cover 113, the normally closed cup cover 21 and the outer contour of the cup body are arranged in a cocircumference when the normally closed cup cover 21 is closed on the dust outlet 111.

[0181] In this invention, the base station 3 is used to dock with at least a portion of the structure of the dust cup 1 of the vacuum cleaner, transferring the dust in the dust cup 1 to the base station 3.

[0182] The base station 3 includes a docking part 31 and a dust collection chamber 34. The dust collection chamber is connected to the dust collection port of the docking part through an airflow channel. The dust collection port of the docking part is connected to the dust discharge port of the dust cup 1 after the dust cup 1 is docked and the normally closed cover plate 21 of the dust cup 1 is opened.

[0183] In one implementation, the base station 3 is further provided with a second suction source, which is used to generate suction airflow in the airflow channel to transfer the garbage in the dust cup 1 to the dust collection chamber 34 through the dust discharge port.

[0184] Correspondingly, the docking part is provided with the unlocking structure at the position corresponding to the pressure plate 22 of the pressure plate 22. This unlocking structure can press against the pressure plate 2211 during the installation of the dust cup 1 on the base station, or after the dust cup is docked with the base station and in the dust collection position, press against the pressure plate 2211 before the base station starts cleaning the dust cup, thereby pushing the pressure plate 22 to slide away from the normally closed cover plate 21, so that the pressure plate 22 is separated from the normally closed cover plate 21, thereby unlocking the normally closed cover plate 21. This allows the normally closed cover plate 21 to open under the action of the suction airflow, and the garbage in the dust cup 1 can be sucked out from the dust outlet into the dust collection chamber by the suction airflow of the second suction source. The movement direction of the pressure plate 22 is parallel to the axis of the second suction source.

[0185] In addition, the dust collection chamber has a clearance space 35, which is used to allow the normally closed cover plate 21 to open, so as to ensure that the normally closed cover plate 21 can be fully opened, thereby ensuring that the garbage in the dust cup 1 is discharged smoothly.

[0186] In both the push-in position and the dust collection position, the floor brush assembly 6 is supported by the base station 3 or by the surface to be cleaned.

[0187] At both the push-in position and the dust collection position, the extension tube 4 is at the same maximum height from the surface to be cleaned in its vertical state. When operating the vacuum cleaner, the user only needs to push the vacuum cleaner to the base station 3 without lifting it. After the floor brush assembly 6 is in place, the user can directly push the main unit 5 towards the base station 3 to achieve docking. Throughout the docking process between the vacuum cleaner and the base station 3, the user only needs to push the vacuum cleaner in a direction away from the body, without lifting it. This convenient operation reduces the steps and effort required for the user to operate the vacuum cleaner, making it more effortless and convenient to use, thus improving the user experience.

[0188] In one embodiment, at the dust collection position, the vacuum cleaner main unit discharges dust from the dust outlet in a generally horizontal direction, and at the dust collection position, the dust collection outlet is in fluid communication with the dust outlet. The vacuum cleaner discharges dust from the side of the dust cup. Compared to bottom dust discharge, side dust discharge reduces the risk of dust leakage from the dust cup when the vacuum cleaner is removed from the base station, avoiding secondary pollution to the environment and improving the user experience.
