Description

[0001] This disclosure claims priority to Chinese patent application No. 202521686999.X, filed on August 7, 2025, entitled "Cleaning System, Handheld Cleaning Device and Base Station", which is incorporated herein by reference in its entirety. Technical Field

[0002] This disclosure relates to the field of handheld cleaning equipment technology, and particularly to a cleaning system, handheld cleaning equipment, and base station. Background Technology

[0003] Handheld cleaning devices (such as handheld vacuum cleaners) work in conjunction with base stations to perform maintenance operations. The handheld cleaning device has a dust outlet, and the base station has a dust inlet. By connecting the dust outlet and the dust inlet, the debris stored in the handheld cleaning device can be transferred to the base station.

[0004] In existing technologies, during the docking process between a handheld cleaning device and a base station, the user lifts the handheld cleaning device and vertically connects the dust outlet and dust inlet from top to bottom. Since the handheld cleaning device has a certain weight, the user must overcome the device's gravity to complete the lifting action. This is especially problematic when the handheld cleaning device is fully loaded, significantly increasing the difficulty and physical exertion required. This docking method is inconvenient to operate. Utility Model Content

[0005] The purpose of this disclosure is to provide a cleaning system, a handheld cleaning device, and a base station to improve the convenience for users to connect handheld cleaning devices to a base station.

[0006] According to a first aspect of this disclosure, a cleaning system is provided. The cleaning system includes a handheld cleaning device and a base station, the base station being used at least for maintaining the handheld cleaning device. The handheld cleaning device includes a floor brush assembly, a wheel assembly, a main body, and a dust cup assembly. The floor brush assembly moves on a surface to be cleaned to clean it; the wheel assembly is connected to the floor brush assembly and is used to drive the floor brush assembly to move; one end of the main body is rotatably connected to the floor brush assembly about a first axis, the main body being able to rotate forward or backward relative to the floor brush assembly about the first axis, the main body driving the wheel assembly to move under the action of an external force, thereby driving the floor brush assembly to move forward or backward to clean the surface to be cleaned; the dust cup assembly is detachably disposed on the main body and includes a dust cup and a cup cover, the dust cup being used to temporarily store the debris collected by the floor brush assembly when cleaning the surface to be cleaned, the bottom of the dust cup having a dust outlet, the cup cover being used to open or close the dust outlet, and the bottom of the dust cup assembly having a first mating surface. The base station includes a base station body and a dust collection container. The top of the base station body has a second mating surface and a dust collection port. The dust collection container is located inside the cavity of the base station body and is used to collect the debris in the dust cup. The dust collection container is connected to the outside through the dust collection port. Under the action of external force, the main body drives the wheel assembly to move, thereby driving the floor brush assembly to move forward. When the handheld cleaning device is docked with the base station, the first and second mating surfaces slide and abut against each other. The planes where the first and second mating surfaces are located are both inclined relative to the horizontal plane.

[0007] According to a second aspect of this disclosure, a handheld cleaning device is provided. The handheld cleaning device is used in conjunction with a base station, which is used at least for maintaining the handheld cleaning device. The base station includes a base station body and a dust collection container. The top of the base station body has a second mating surface and a dust collection port. The dust collection container is disposed within a cavity of the base station body and communicates with the outside through the dust collection port. The handheld cleaning device includes a floor brush assembly, a wheel assembly, a main body, and a dust cup assembly. The floor brush assembly moves across the surface to be cleaned to clean it. A wheel assembly is connected to the floor brush assembly and drives its movement. One end of the main body is rotatably connected to the floor brush assembly around a first axis. The main body can rotate forward or backward relative to the floor brush assembly around the first axis. Under external force, the main body drives the wheel assembly, thereby driving the floor brush assembly forward or backward to clean the surface. A dust cup assembly is detachably mounted on the main body and includes a dust cup and a lid. The dust cup temporarily stores debris collected by the floor brush assembly while cleaning the surface. A dust outlet is located at the bottom of the dust cup, and the lid opens or closes the outlet. The bottom of the dust cup assembly has a first mating surface, and a dust collection container collects debris from the dust cup. Under external force, the main body drives the wheel assembly, which in turn moves the floor brush assembly forward. When the handheld cleaning device is docked to the base station, the first and second mating surfaces slide together and abut against each other. Both the planes of the first and second mating surfaces are inclined relative to the horizontal plane.

[0008] According to a third aspect of this disclosure, a base station is provided. The base station is used in conjunction with a handheld cleaning device and is at least used for maintaining the handheld cleaning device. The handheld cleaning device includes a floor brush assembly, a wheel assembly, a main body, and a dust cup assembly. The floor brush assembly moves on a surface to be cleaned to clean it. The wheel assembly is connected to the floor brush assembly and is used to drive the floor brush assembly to move. One end of the main body is rotatably connected to the floor brush assembly about a first axis. The main body can rotate forward or backward relative to the floor brush assembly about the first axis. Under the action of an external force, the main body drives the floor brush assembly to move forward or backward to clean the surface to be cleaned. The dust cup assembly is detachably disposed on the main body and includes a dust cup and a cup lid. The dust cup is used to temporarily store the debris collected by the floor brush assembly when cleaning the surface. A dust outlet is opened at the bottom of the dust cup, and the cup lid is used to open or close the dust outlet. The bottom of the dust cup assembly has a first mating surface. The base station includes a base station body and a dust collection container. The top of the base station body has a second mating surface and a dust collection port. The dust collection container is located inside the cavity of the base station body and is used to collect the debris in the dust cup. The dust collection container is connected to the outside through the dust collection port. Under the action of external force, the main body drives the wheel assembly to move, thereby driving the floor brush assembly to move forward. When the handheld cleaning device is docked with the base station, the first and second mating surfaces slide and abut against each other. The planes where the first and second mating surfaces are located are both inclined relative to the horizontal plane.

[0009] When the user wants to return the handheld cleaning device to the base station (e.g., after a cleaning task is completed, or when pausing the cleaning task to return the handheld cleaning device to the base station for dust collection or charging), the user continues to push the handheld cleaning device forward towards the base station. This applies force to the main body of the device, pushing the wheel assembly forward, which in turn moves the floor brush assembly forward until the floor brush assembly reaches the base station. After the floor brush assembly reaches its predetermined position on the base station, the wheel assembly and floor brush assembly stop moving forward. The user then pushes the main body forward, causing it to rotate forward relative to the floor brush assembly. This allows the first and second mating surfaces to slide and engage, facilitating the connection and connection between the dust outlet and the dust collection port during dust collection, allowing debris in the dust cup to enter the dust collection container. In this disclosure, the user can continue to push the handheld cleaning device forward towards the base station using the same grip position and pushing direction as when performing a cleaning task, without needing to change the grip position or operating direction, making operation convenient. This disclosure fully utilizes the cooperation between the wheel assembly, the first mating surface, and the second mating surface during the process of placing the handheld cleaning device back into the base station. This solves the problem of the laborious manual lifting required in existing technologies that do not utilize wheels. During the movement of the floor brush assembly to the base station, the pushing force of the wheel assembly and the sliding cooperation between the first and second mating surfaces allow for docking with only a small pushing force, greatly reducing the operational burden and making the docking process smoother and more efficient. Therefore, this disclosure improves the convenience for users to dock the handheld cleaning device to the base station, saving time and effort. Furthermore, after docking, both the handheld cleaning device and the base station remain stable and are not easily tipped over. Attached Figure Description

Detailed Implementation

[0043] In the following description, numerous details are provided to enable a thorough understanding of this disclosure. However, those skilled in the art will appreciate that the following description merely illustrates preferred embodiments of the disclosure, and that the disclosure can be practiced without one or more of these details. Furthermore, to avoid confusion with this disclosure, some technical features well-known in the art have not been described in detail.

[0044] Handheld cleaning devices are used to clean surfaces, including but not limited to floors, desktops, doorways, and walls. These devices work in conjunction with base stations to perform maintenance operations at the base station; for example, they can transfer temporarily stored debris to the base station. Taking a handheld vacuum cleaner as an example, the vacuum cleaner uses negative pressure to suck debris into a dust cup for temporary storage. The handheld cleaning device has a dust outlet connected to the dust cup, and the base station has a dust inlet. By connecting the dust outlet and the dust inlet, the temporarily stored debris in the dust cup can be transferred to the base station.

[0045] In related technologies, users need to lift the handheld cleaning device and vertically connect the dust outlet and dust inlet from top to bottom. Because handheld cleaning devices have a certain weight, especially when fully loaded, the difficulty of operation and physical exertion increase significantly.

[0046] Based on this, the inventors proposed a new docking scheme to improve the convenience for users to dock handheld cleaning devices with base stations.

[0047] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of the handheld cleaning device 20 and the base station 10 in a cleaning system 100 provided in an embodiment of this disclosure.

[0048] This application provides a cleaning system 100, which includes a handheld cleaning device 20 and a base station 10. The base station 10 is used for at least the maintenance of the handheld cleaning device 20, including but not limited to charging, dust collection, dust scraping, cleaning brushes, and storing accessories. For example, the base station 10 is used to collect temporarily stored waste (dry waste and / or wet waste) in the handheld cleaning device 20, or to charge the handheld cleaning device 20, or to clean the handheld cleaning device 20.

[0049] The handheld cleaning device 20 can be a handheld vacuum cleaner, a handheld washer-mop combo, or other handheld cleaning devices. The following text will use a handheld vacuum cleaner as an example.

[0050] The handheld cleaning device 20 is used to clean the surface S1 to be cleaned. The surface S1 to be cleaned is, for example, the ground. The handheld cleaning device 20 can collect debris on the surface S1 to be cleaned.

[0051] The most direct meaning of "handheld" is that the device is equipped with a structure suitable for hand grip (such as a handle, grip, etc.), and users can operate the device by holding it with one hand or with the assistance of both hands.

[0052] In the usage scenarios of handheld cleaning devices 20, the definition of "forward and backward direction" is usually based on the user's operating posture, that is, the "user's own orientation." When the user holds the device, their own "forward and backward" direction is consistent with the device's "forward and backward" direction. "Forward" refers to the direction in front of the user's line of sight, or the direction the user is facing (for example, when cleaning the floor with a handheld vacuum cleaner, the user stands behind the handheld vacuum cleaner and holds it in their hand; pushing forward is "forward"). "Backward" refers to the direction behind the user's line of sight, or the direction the user is facing away from (for example, when cleaning the floor with a handheld vacuum cleaner, the user stands behind the handheld vacuum cleaner and holds it in their hand; pulling back is "backward"). The logic of this definition is that when the user operates, the device's movement direction is synchronized with their own action (pushing forward = device "forward", pulling back = device "backward"), which conforms to the intuition of daily operation (similar to the "forward and backward" judgment when using a mop or broom).

[0053] In the use of handheld cleaning devices, the definition of "left and right directions" is also based on the user's operating posture. "Left": refers to the direction to the left of the user (for example, when cleaning the floor with a handheld vacuum cleaner, the direction of moving the device to the left of the body is "left"). "Right": refers to the direction to the right of the user (for example, when cleaning the floor with a handheld vacuum cleaner, the direction of moving the device to the right of the body is "right").

[0054] Please refer to the following: Figure 2 , Figure 2 yes Figure 1 A three-dimensional cross-sectional view of the handheld cleaning device 20 in the cleaning system 100 shown. In some embodiments, the handheld cleaning device 20 includes a floor brush assembly 210, a wheel assembly 200, a main body 220, and a dust cup assembly 230.

[0055] The floor brush assembly 210 moves on the surface S1 to be cleaned to clean it. Specifically, Figure 1In the cleaning system 100 shown, the floor brush assembly 210 includes a brush head housing 211, a roller brush 212, and a connecting mechanism 213. The brush head housing 211 is the main structural component of the floor brush assembly 210, supporting the other parts. The brush head housing 211 forms a suction chamber 215, which communicates with the outside through a suction port 216 located at the bottom of the brush head housing 211. Debris enters the suction chamber 215 through the suction port 216. The design of the suction chamber 215 typically takes into account the smooth flow of air to ensure that debris can be smoothly sucked into the dust cup 231 described below. A roller brush 212 is rotatably mounted on the brush head housing 211 to assist in conveying debris into the suction chamber 215. For example, the roller brush 212 can be positioned at the suction port 216 of the brush head housing 211. The roller brush 212 contacts the surface to be cleaned to adsorb or roll up the debris, allowing it to enter the suction chamber 215 more smoothly. For example, the roller brush 212 can be positioned on the bottom front side of the brush head housing 211. A connecting mechanism 213 connects the brush head housing 211 to the main body 220. The specific structure of the floor brush assembly 210 is not limited to this; other reasonable structures are also acceptable.

[0056] The wheel assembly 200 is connected to the floor brush assembly 210 and is used to drive the floor brush assembly 210 to move. In some embodiments, the wheel assembly 200 includes a pivot 201 and a drive wheel 202. The pivot 201 is connected to the floor brush assembly 210, and the drive wheel 202 is connected to the pivot 201 and can rotate relative to the pivot 201. See also Figure 2 and Figure 8 For example, the rotating shaft 201 is connected to the connecting mechanism 213. For instance, the rotating shaft 201 passes through the connecting mechanism 213 and its two ends protrude from the connecting mechanism 213. The two traveling wheels 202 are respectively connected to the two ends of the rotating shaft 201. The rotating shaft 201 is on the same straight line as the first axis L1, or the rotating shaft 201 is parallel to the first axis L1. Alternatively, the two rotating shafts 201 are respectively connected to the two sides of the connecting mechanism 213, and the two traveling wheels 202 are respectively connected to the two rotating shafts 201 one by one. That is, one end of one rotating shaft 201 is connected to the left side of the connecting mechanism 213 and the other end is connected to one traveling wheel 202, and one end of the other rotating shaft 201 is connected to the right side of the connecting mechanism 213 and the other end is connected to another traveling wheel 202. In another example, the pivot 201 is connected to the brush head housing 211, for example, the pivot 201 is connected to the bottom of the brush head housing 211, and the wheel 202 passes through the pivot 201 or is connected to either end of the pivot 201. For example, the wheel 202 can be circular, and the pivot 201 can be cylindrical.

[0057] It should be noted that the number of pivots 201 can be one, two, or more, and the number of wheels 202 can be one, two, or more. Wheels 202 can be located at one end of the pivot 201 or can be mounted on the pivot 201. One, two, or more wheels 202 can be mounted on the pivot 201. The arrangement, location, number, size, and shape of the pivots 201 and wheels 202 can be customized according to actual needs, and this disclosure does not impose any restrictions on them.

[0058] When the handheld cleaning device 20 performs a cleaning task on the surface S1 to be cleaned, both the traveling wheels 202 and the roller brush 212 are in contact with the surface S1. The traveling wheels 202 roll on the surface S1 to drive the floor brush assembly 210 to move, which reduces the resistance of the brush head housing 211 or the roller brush 212 to the movement of the surface S1. The roller brush 212 rolls on the surface S1 to rub the surface S1. The traveling wheels 202 can be located on either side of the roller brush 212, such as the rear side (see [link]). Figure 2 , Figure 8 For example, the left, right, or front sides can all assist in the movement of the floor brush assembly 210, avoiding direct contact and friction between the brush head housing 211 and the surface S1 to be cleaned. This would wear down the brush head housing 211 and shorten its lifespan, and would also cause excessive resistance to the movement of the floor brush assembly 210. With the assistance of the wheel assembly 200, the movement of the floor brush assembly 210 is smoother.

[0059] One end of the main body 220 is rotatably connected to the floor brush assembly 210 around the first axis L1. The main body 220 can rotate forward or backward relative to the floor brush assembly 210 around the first axis L1. Under the action of external force, the main body 220 drives the wheel assembly 200 to move, thereby driving the floor brush assembly 210 to move forward or backward to clean the surface S1 to be cleaned.

[0060] Specifically, Figure 1 In the cleaning system 100 shown, when the floor brush assembly 210 moves on the surface S1 to be cleaned, the first axis L1 is parallel to the horizontal plane S and perpendicular to the direction of movement of the floor brush assembly 210. It should be noted that "parallel" and "perpendicular" in this text mean approximately parallel and approximately perpendicular, and deviations caused by unevenness of the surface S1 to be cleaned, assembly errors between the rotating shaft 201 and the connecting mechanism 213, etc., are allowed.

[0061] The attitude of the first axis L1 determines the trajectory of the dust cup assembly 230 when the main body 220 rotates forward.

[0062] Traditional vertical docking requires the user to "lift the handheld device upwards and then align it downwards." However, in this solution, the first axis L1 is horizontally positioned and extends in the left-right direction, transforming the docking action into "pushing the floor brush assembly 210 forward to the predetermined position P0, and then rotating the main body 220 forward." After the floor brush assembly 210 is in the predetermined position P0, because the first axis L1 is perpendicular to the front-back direction and parallel to the horizontal plane S, when the main body 220 rotates forward, the first mating surface 2312 of the dust cup assembly 230 and the second mating surface 1101 of the base station 10 slide and abut against each other. The dust outlet 2311 naturally moves closer to the dust collection port 1102 in front along the rotation trajectory, without the need for additional left-right adjustments.

[0063] The forward rotation direction (pushing forward with the arm) conforms to the human body's "pushing" force habit (the lever arm of pushing is longer and requires less effort). Compared with "lifting upward" (which requires resisting the weight of the equipment and has a shorter lever arm), the operating force can be greatly reduced, especially when the equipment is fully loaded. In addition, it can be performed smoothly after the cleaning task is completed, and the handheld cleaning device 20 can be pushed forward towards the base station 10 without changing the grip position or pushing direction. The operation is simple and convenient.

[0064] Specifically, Figure 1 In the cleaning system 100 shown, the main body 220 includes a rod 221, a handle 222, and a main unit 223. One end of the rod 221 is rotatably connected to the floor brush assembly 210 around a first axis L1. The two ends of the handle 222 are respectively connected to the other end of the rod 221 and the main unit 223. When the user grips the handle 222 or the rod 221, force is applied to drive the wheel assembly 200 (e.g., the walking wheels 202 roll) via the rod 221, thereby driving the floor brush assembly 210 to move forward or backward. One end of the rod 221 is connected to the brush head housing 211 via the aforementioned connecting mechanism 213. The connecting mechanism 213 is configured such that the rod 221 and the brush head housing 211 can rotate relative to each other around the first axis L1. A channel 2211 is formed inside the rod 221. One end of the channel 2211 communicates with the suction chamber 215, and the other end communicates with the first dust collection chamber 2315 of the dust cup 231. The main unit 223 is used to create negative pressure in the first dust collection chamber 2315, for example, by installing a fan inside the main unit. Waste sucked in from the suction port 216 is driven by the airflow along the channel 2211 into the first dust collection chamber 2315 of the dust cup 231. The specific structure of the main body 220 is not limited to this; other reasonable structures are also acceptable.

[0065] Users can choose which part of the handheld cleaning device 20 to hold according to their personal habits, such as holding the handle 222 or the handle 221. The user holds the main body 220 and applies force to it, thereby driving or guiding the floor brush assembly 210 to move with the assistance of the wheel assembly 200, for example, driving the floor brush assembly 210 forward or backward. During the movement of the floor brush assembly 210, the main body 220 can also rotate forward or backward relative to the floor brush assembly 210 around the first axis L1.

[0066] In the design of the handheld cleaning device 20, the rotating connection between the floor brush assembly 210 and the main body 220 is a conventional design. This rotating connection offers the following advantages: 1. Enhanced cleaning flexibility and adaptability to complex terrain. The rotating connection allows the floor brush assembly 210 to rotate flexibly relative to the main body 220, easily conforming to uneven, recessed, or sloping areas of the ground. 2. Reduced operational difficulty and improved ease of use. During cleaning, users do not need to deliberately bend over or twist their arms to adjust the angle of the main body 220; the floor brush assembly 210 can adapt to the surface S1 to be cleaned simply by rotating autonomously, reducing fatigue during prolonged use (especially suitable for cleaning low areas or high crevices). Furthermore, due to differences in height and build among family members, it can accommodate different users with varying heights or arm lengths, enhancing user comfort.

[0067] The dust cup assembly 230 is detachably mounted on the main body 220 and includes a dust cup 231 and a lid 232. The dust cup 231 is used to temporarily store debris collected by the brush assembly 210 when cleaning the surface S1 to be cleaned. A dust outlet 2311 is provided at the bottom of the dust cup 231. The lid 232 is used to open or close the dust outlet 2311. The bottom of the dust cup assembly 230 has a first mating surface 2312. Specifically, Figure 1 In the cleaning system 100 shown, the dust cup assembly 230 is detachably mounted on the main unit 223. The dust cup 231 has a first dust collection chamber 2315 for temporarily storing waste. The first dust collection chamber 2315 communicates with the outside through a dust outlet 2311. Exemplarily, the first mating surface 2312 is the bottom surface of the dust cup 231, for example, the bottom surface of the dust cup 231 excluding the cup lid 232. In another exemplary embodiment, the first mating surface 2312 is the outer peripheral wall surface of the dust cup 231, for example, the outer peripheral wall surface of the dust cup 231 near the cup lid 232.

[0068] The dust cup assembly 230 is detachable, facilitating dust emptying (without passing through the base station 10) and cleaning, thus avoiding secondary pollution. For example, for handheld cleaning devices 20 without a base station 10, the dust cup assembly 230 can be detached when the user needs to empty the dust.

[0069] Please see Figure 3 and Figure 4 . Figure 3 yes Figure 1 A three-dimensional cross-sectional view of base station 10 in the cleaning system 100 shown. Figure 4 yes Figure 3 A magnified view of partial view E1.

[0070] Base station 10 includes a base station body 110 and a dust collection container 120. The top of the base station body 110 has a second mating surface 1101 and a dust collection port 1102. The dust collection container 120 is disposed within the cavity of the base station body 110 and is used to collect waste from the dust cup 231. In some embodiments, the dust collection container 120 is detachably installed within the cavity of the base station body 110, allowing users to easily remove it for emptying or replacement. Exemplarily, the dust collection container 120 can be a dust bag, dust bin, dust cup, or other container; it can be disposable or reusable. The dust collection container 120 communicates with the outside world through the dust collection port 1102. Specifically, the dust collection container 120 has a second dust collection chamber 1201, which communicates with and is connected to the outside world through the dust collection port 1102.

[0071] Specifically, Figure 1 In the cleaning system 100 shown, the base station 10 also includes a negative pressure generator 121. The negative pressure generator 121 is disposed within the base station body 110 and is used to create negative pressure within the second dust collection chamber 1201. This facilitates the transfer of debris from the first dust collection chamber 2315 to the second dust collection chamber 1201 when the dust outlet 2311 connects with the dust collection outlet 1102. For example, the negative pressure generator 121 can be a fan, which creates negative pressure in both the first and second dust collection chambers 2315 by drawing air to suck debris from the dust cup 231 into the dust collection container 120. In some other embodiments, the negative pressure generator 121 may not be provided, and the debris in the first dust collection chamber 2315 may be transferred to the second dust collection chamber 1201 by gravity or other means (e.g., vibration).

[0072] Please see Figures 5 to 7 . Figure 5 yes Figure 1 The diagram shows the process of the handheld cleaning device 20 connecting to the base station 10 in the cleaning system 100. Figure 6 yes Figure 1 The diagram shows a cross-sectional view of the handheld cleaning device 20 after it is docked to the base station 10 in the cleaning system 100. Figure 7 yes Figure 6 A magnified view of partial view E2.

[0073] Under the action of external force, the main body 220 drives the brush assembly 210 to move forward, so that when the handheld cleaning device 20 is docked with the base station 10, the first mating surface 2312 and the second mating surface 1101 slide and abut against each other. The plane where the first mating surface 2312 is located and the plane where the second mating surface 1101 is located are both inclined relative to the horizontal plane S.

[0074] In some embodiments, the angle θ between the first mating surface 2312 and / or the second mating surface 1101 and the horizontal plane S is 5°-20°. Optionally, the angle is 5°, 7°, 9°, 10°, 12°, 15°, 18°, or 20°. Exemplarily, in the direction from back to front, the first mating surface 2312 and / or the second mating surface 1101 may be inclined upwards relative to the horizontal plane S (i.e., above the horizontal plane S, such as...). Figure 7 As shown), it can also be tilted downwards (that is, below the horizontal plane S).

[0075] The plane containing the first mating surface 2312 and the plane containing the second mating surface 1101 are inclined relative to the horizontal plane S. This refers to the state when the handheld cleaning device 20 is upright (i.e., when the rod 221 is perpendicular to the horizontal plane S) and when the base station 10 is placed on the horizontal plane S. Since both the plane containing the first mating surface 2312 and the plane containing the second mating surface 1101 are inclined relative to the horizontal plane S, the first mating surface 2312 can abut against the second mating surface 1101 during the forward rotation of the main body 220 relative to the brush assembly 210, resulting in a better sealing effect. Consequently, the dust outlet 2311 can connect to the dust collection port 1102, preventing air leakage during dust collection operations.

[0076] In some embodiments, the first mating surface 2312 and / or the second mating surface 1101 can be a plane or a non-planar surface (e.g., a curved surface); for example, both the first mating surface 2312 and the second mating surface 1101 are planes; in another example, both the first mating surface 2312 and the second mating surface 1101 are curved surfaces, for example, one of the first mating surface 2312 and the second mating surface 1101 is a concave surface and the other is a convex surface; both can be smooth curved surfaces or uneven curved surfaces, as long as they can completely abut each other when mated. It should be noted that when the first mating surface 2312 and the second mating surface 1101 are non-planar, the plane containing the first mating surface 2312 can be any plane perpendicular to the central axis of the first mating surface 2312, and the plane containing the second mating surface 1101 can be any plane perpendicular to the central axis of the second mating surface 1101.

[0077] In some embodiments, when the handheld cleaning device 20 is docked to the base station 10, the plane containing the first mating surface 2312 and the plane containing the second mating surface 1101 are relatively parallel. It is understood that their relative parallelism ensures proper contact during docking and guarantees a sealing effect. It should be noted that "relatively parallel" in this document means approximately parallel, allowing for assembly errors during docking or assembly.

[0078] Base station 10 has a storage area at a predetermined position P0 to store the ground brush assembly 210. When the ground brush assembly 210 is at the predetermined position P0, the dust outlet 2311 and the dust collection port 1102 are positioned opposite each other on the circumferential direction F of the first axis L1, with the dust collection port 1102 located in front of the dust outlet 2311. The main body 220 rotates forward relative to the ground brush assembly 210, causing the dust outlet 2311 to move closer to the dust collection port 1102 on the circumferential direction F of the first axis L1. The main body 220 rotates backward relative to the ground brush assembly 210, causing the dust outlet 2311 to move away from the dust collection port 1102 on the circumferential direction F of the first axis L1.

[0079] The dust outlet 2311 and the dust collection port 1102 are positioned opposite each other on the circumferential direction F of the first axis L1. Specifically, the dust outlet 2311 will form an arc-shaped motion trajectory when it rotates around the first axis L1, and the dust collection port 1102 is located on this motion trajectory.

[0080] After the cleaning task is completed, the user can continue to hold the main body 220 and push the brush assembly 210 towards the base station 10. With the assistance of the wheel assembly 200, the brush assembly 210 is pushed to the predetermined position P0. Then, the main body 220 is rotated forward until the first mating surface 2312 and the second mating surface 1101 slide and abut against each other, thereby connecting the dust outlet 2311 with the dust collection outlet 1102. Traditional vertical docking methods require the user to lift the device against its own weight, such as by holding the lever 211 to lift the entire handheld cleaning device 20. This is especially true when the cleaning device is fully loaded, significantly increasing the difficulty and physical exertion. In contrast, with this invention, the user continues to push the handheld cleaning device 20 towards the base station 10 from the same holding position and pushing direction as when performing the cleaning task. There is no need to change the holding position or operating direction. Once the brush assembly 210 reaches the base station 10, only a small pushing force is required to complete the docking. This makes the operation easier, greatly reducing the operational burden, and the docking process is smoother and more efficient. Therefore, this disclosure improves the convenience for users to connect the handheld cleaning device 20 to the base station 10 (that is, improves the convenience of connecting the dust outlet 2311 and the dust collection port 1102), saving time and effort. Furthermore, after the handheld cleaning device 20 and the base station 10 are connected, their states are stable and they are not easily tipped over. This disclosure fully utilizes the cooperation between the wheel assembly 200, the first mating surface 2312, and the second mating surface 1101, solving the problem of the laborious manual lifting required in the prior art due to the lack of wheels. During the movement of the floor brush assembly 210 to the base station 10, the pushing force of the wheel assembly 200 and the sliding cooperation between the first mating surface 2312 and the second mating surface 1101 allow for connection with only a small pushing force, greatly reducing the operational burden and making the connection process smoother and more efficient.

[0081] Please see Figure 4 In some embodiments, when the first mating surface 2312 and the second mating surface 1101 abut against each other, a sealing structure can be formed around the dust outlet 2311 and the dust collection port 1102 to prevent garbage from overflowing and to ensure airtightness during dust collection operations.

[0082] Specifically, at least one of the base station 10 and the handheld cleaning device 20 further includes a seal 191. Exemplarily, the seal 191 is embedded in at least one of the first mating surface 2312 and the second mating surface 1101, for example, the seal 191 is embedded in the second mating surface 1101, and the seal 191 surrounds the dust collection port 1102. When the first mating surface 2312 and the second mating surface 1101 abut against each other, the seal 191 is elastically held between the first mating surface 2312 and the second mating surface 1101. The seal 191 is, for example, made of rubber. In other embodiments, the seal 191 may also be embedded in the first mating surface 2312 and surround the dust outlet 2311 or the cup lid 232. In other embodiments, the seal 191 may be embedded in both the first mating surface 2312 and the second mating surface 1101.

[0083] Please see Figure 8 and Figure 9 . Figure 8 yes Figure 1 The cleaning system 100 shown is illustrated in a three-dimensional structural diagram of the floor brush assembly 210 located in the receiving cavity 1103. Figure 9 yes Figure 6 A magnified view of partial view E3.

[0084] The base station body 110 also has a cavity 1103 and an opening 1104 connecting the cavity 1103 to the outside. The floor brush assembly 210 enters and exits the cavity 1103 through the opening 1104. When the handheld cleaning device 20 is connected to the base station 10, at least a part of the floor brush assembly 210 is housed in the cavity 1103.

[0085] For example, the position where the foremost tip of the local brush assembly 210 contacts the first sidewall 1107 of the receiving cavity 1103 can be the aforementioned predetermined position P0.

[0086] After the user finishes cleaning, the floor brush assembly 210 is pushed into the receiving cavity 1103 through the opening 1104, and then the main body 220 is rotated forward until the first mating surface 2312 and the second mating surface 1101 slide and abut against each other, thereby allowing the handheld cleaning device 20 to connect with the base station 10.

[0087] At least a portion of the floor brush assembly 210 is housed in the receiving cavity 1103. The base station body 110 can cover at least a portion of the floor brush assembly 210, which saves the floor brush assembly 210's footprint. On the other hand, the cleaning system 100 is simpler overall and has a better appearance. At the same time, it avoids the situation where users trip when passing the base station 10 due to the exposed floor brush assembly 210.

[0088] In some other embodiments, not shown in the figures, when the floor brush assembly 210 is located at a predetermined position P0, it can also be completely exposed outside the base station body 110. For example, the base station body 110 is provided with a support platform for supporting the floor brush assembly 210. The support platform is configured to be able to directly push the floor brush assembly 210 from the surface to be cleaned S1 onto the support platform to save effort.

[0089] In some other embodiments, not shown in the figures, the floor brush assembly 210 may be located at a predetermined position P0 but not at the base station body 110. For example, the floor brush assembly 210 may be located on the surface to be cleaned S1 and adjacent to the base station body 110. In order to enable the user to accurately identify the predetermined position P0, a mark may be provided on the outer wall of the base station body 110 to instruct the user to place the floor brush assembly 210 against the mark.

[0090] In the case of setting up the receiving cavity 1103 to receive the floor brush assembly 210, the following improvements are made so that the user can directly push the floor brush assembly 210 on the surface to be cleaned S1 into the receiving cavity 1103.

[0091] In some embodiments, the inner wall of the accommodating cavity 1103 has a bottom wall 1105 for supporting the floor brush assembly 210, the height of which gradually decreases in the direction toward the opening 1104. The height refers to the vertical distance between the bottom wall 1105 and the surface S1 to be cleaned.

[0092] Specifically, the height of the bottom edge of the opening 1104 from the surface S1 to be cleaned is configured such that the floor brush assembly 210 can move from the surface S1 to the receiving cavity 1103 without requiring a lifting action by the user. In the front-to-back direction, the bottom wall 1105 extends outward within the receiving cavity 1103 and gradually decreases in height, with the extended end of the bottom wall 1105 forming the bottom edge of the opening 1104.

[0093] When the receiving cavity 1103 is provided to receive the floor brush assembly 210, the floor brush assembly 210 can be limited by the inner wall of the receiving cavity 1103 so that the position of the floor brush assembly 210 is accurate.

[0094] Specifically, in some embodiments, the inner wall surfaces of the accommodating cavity 1103 include a top wall 1106 and a bottom wall 1105 vertically opposite each other, and a first side wall 1107 and two second side walls 1108 connected between the top wall 1106 and the bottom wall 1105. The two second side walls 1108 are arranged opposite each other and spaced apart in the left-right direction. The first side wall 1107 is connected between the two second side walls 1108 and is arranged opposite to the opening 1104 in the front-back direction.

[0095] After the user finishes cleaning, the floor brush assembly 210 is pushed into the receiving cavity 1103 through the opening 1104 until the floor brush assembly 210 abuts against the first sidewall 1107 in the front-back direction. At this point, the floor brush assembly 210 is at the predetermined position P0. The two second sidewalls 1108 are used to restrict the position of the floor brush assembly 210 in the left-right direction.

[0096] Please see Figure 10 , Figure 10 yes Figure 1 The diagram shows the process in which the second mating surface 1101 passes over the limiting part 1301 and abuts against the first mating surface 2312 in the cleaning system 100 shown.

[0097] In some embodiments, the base station body 110 further includes a limiting portion 1301. The limiting portion 1301 protrudes from the second mating surface 1101. The limiting portion 1301 is located behind the dust collection port 1102. When the handheld cleaning device 20 is docked to the base station 10, the limiting portion 1301 is used to prevent the dust cup assembly 230 from moving backward.

[0098] By setting the limiting part 1301, when the handheld cleaning device 20 is connected to the base station 10, the limiting part 1301 can block the dust cup assembly 230 from moving backward, thereby preventing the first mating surface 2312 and the second mating surface 1101 from separating.

[0099] Because of the limiting part 1301, during the process of the handheld cleaning device 20 docking with the base station 10, the limiting part 1301 will block the first mating surface 2312 from approaching the second mating surface 1101. In order to enable the first mating surface 2312 to smoothly approach the second mating surface 1101, the following improvements are made.

[0100] Please see Figure 10 , Figure 11 and Figure 12 . Figure 11 yes Figure 1 A three-dimensional structural diagram of a portion of the handheld cleaning device 20 in the cleaning system 100 shown. Figure 12 yes Figure 1 The front view of a portion of the structure of the base station 10 in the cleaning system 100 shown.

[0101] When the handheld cleaning device 20 is docked to the base station 10, the distance between the top of the limiting part 1301 and the first axis L1 in the radial direction is a first dimension D1. The first mating surface 2312 has a first edge 2313 at the front end and a second edge 2314 at the rear end. In the radial direction of the first axis L1, the distances between the first edge 2313 and the second edge 2314 and the first axis L1 are a second dimension D2 and a third dimension D3, respectively. The first dimension D1 is smaller than the second dimension D2 and larger than the third dimension D3, so that the first mating surface 2312 can slide and engage with the limiting part 1301 during forward rotation around the first axis L1, and pass over the limiting part 1301 under the pushing action of the limiting part 1301.

[0102] After the floor brush assembly 210 is positioned at the predetermined position P0, during the forward rotation of the main body 220 relative to the floor brush assembly 210 around the first axis L1, the limiting part 1301 may have multiple parts that can block the first mating surface 2312. For example... Figure 12 As shown in the dashed box, multiple portions between the first position P1 and the second position P2 may obstruct the first mating surface 2312. Among them, the portion furthest from the first axis L1 in the radial direction is the top end of the aforementioned limiting portion 1301.

[0103] Specifically, the first dimension D1 is the maximum vertical distance from any point on the top of the limiting part 1301 to the first axis L1. The second dimension D2 is the maximum vertical distance from any point on the first edge 2313 to the first axis L1. The third dimension D3 is the minimum vertical distance from any point on the second edge 2314 to the first axis L1.

[0104] After the floor brush assembly 210 is located at the predetermined position P0, during the process of the main body 220 rotating forward relative to the floor brush assembly 210 around the first axis L1, the part of the first mating surface 2312 that first contacts the limiting part 1301 is the first edge 2313, and the part that last contacts the limiting part 1301 is the second edge 2314.

[0105] Since the first dimension D1 is smaller than the second dimension D2 and larger than the third dimension D3, when the first mating surface 2312 abuts against the limiting part 1301, the abutment position is located between the first edge 2313 and the second edge 2314. A sliding fit structure is formed between the first mating surface 2312 and the limiting part 1301. This sliding fit structure allows the fuselage body 220 to rotate forward in the circumferential direction F of the first axis L1 while moving upward in the vertical direction. When the first mating surface 2312 (second edge 2314) separates from the limiting part 1301, the fuselage body 220 falls under the action of gravity, causing the first mating surface 2312 to abut against the second mating surface 1101.

[0106] In this embodiment, after the user pushes the floor brush assembly 210 to the predetermined position P0, the main body 220 is only pushed forward to rotate, without the need to lift the main body 220 upward.

[0107] In some embodiments, the limiting part 1301 may not be provided, or other methods may be used to maintain the first mating surface 2312 and the second mating surface 1101 abutting against each other. For example, the first mating surface 2312 and the second mating surface 1101 may be maintained abutting against each other by the weight of the handheld cleaning device 20, magnetic adsorption, or a locking device. In embodiments without the limiting part 1301, after the floor brush assembly 210 is located at the predetermined position P0, the main body 220 is no longer obstructed during its forward rotation relative to the floor brush assembly 210 around the first axis L1. The first mating surface 2312 rotates forward in the circumferential direction F of the first axis L1 until it abuts against the second mating surface 1101.

[0108] Please continue reading. Figures 10 to 12 In some embodiments, the base station body 110 further includes a limiting member 1922, which protrudes from the second mating surface 1101 and surrounds the dust collection port 1102, forming a top-open receiving cavity 1302. When the first mating surface 2312 abuts against the second mating surface 1101, the bottom of the dust cup assembly 230 is accommodated in the receiving cavity 1302, wherein a portion of the limiting member 1922 forms a limiting portion 1301.

[0109] Please see Figure 4 Specifically, in Figure 1 In the cleaning system 100 shown, the base station body 110 includes a first housing 190 and a second housing 192.

[0110] The aforementioned receiving cavity 1103 and opening 1104 are provided at the lower part of the first housing 190. The dust collection container 120 is disposed inside the first housing 190.

[0111] The second housing 192 is disposed on the first housing 190 and located above the first housing 190. In some embodiments, the first housing 190 and the second housing 192 are integrally formed structures, or they can be separate structures connected together.

[0112] The second housing 192 includes a support member 1921 and a limiting member 1922.

[0113] The support member 1921 is disposed on the first housing 190 and located above the first housing 190. The top surface of the support member 1921 forms the aforementioned second mating surface 1101. The aforementioned dust collection port 1102 is formed on the support member 1921. In some embodiments, the support member 1921 and the first housing 190 are integrally formed structures, or they can be separate structures connected together.

[0114] The limiting member 1922 protrudes from the second mating surface 1101 of the bearing member 1921. In some embodiments, the bearing member 1921 and the limiting member 1922 are integrally formed, or they can be separate structures connected together.

[0115] The second housing 192 includes, but is not limited to, the support member 1921 and the limiting member 1922, and may also include other components as needed.

[0116] During the docking of the handheld cleaning device 20 to the base station 10, after the first mating surface 2312 passes the limiting part 1301, the bottom of the dust cup assembly 230 falls into the receiving cavity 1302 from the top opening of the receiving cavity 1302. The limiting member 1922 limits the dust cup assembly 230 around the bottom of the dust cup assembly 230, so that the handheld cleaning device 20 can be placed more stably on the base station 10.

[0117] Please see Figure 7 In some embodiments, the base station 10 further includes a first magnet 140 connected to the base station body 110. The handheld cleaning device 20 further includes a second magnet 240 connected to the dust cup assembly 230. When the handheld cleaning device 20 is docked to the base station 10, the second magnet 240 is magnetically connected to the first magnet 140.

[0118] Specifically, in Figure 1 In the cleaning system 100 shown, a first magnet 140 is disposed on a first housing 190 in the base station body 110, and a second magnet 240 is disposed on a dust cup 231 in the dust cup assembly 230. When the handheld cleaning device 20 is docked to the base station 10, the second magnet 240 and the first magnet 140 are adjacent to each other and are magnetically connected, so that the dust cup assembly 230 is fixed in position relative to the base station body 110.

[0119] The positions of the first magnet 140 and the second magnet 240 can be flexibly adjusted. For example, the first magnet 140 can be integrated into the limiting structure of the base station body 110 (such as the inner wall of the cavity 1302), and the second magnet 240 can be correspondingly disposed on the outer wall of the dust cup 231; or the first magnet 140 can be embedded next to the seal 191 of the second mating surface 1101 of the base station 10, and the second magnet 240 can be correspondingly disposed on the edge of the first mating surface 2312 of the dust cup 231, as long as the two can form an effective magnetic attraction when they are docked.

[0120] The first magnet 140 can be exposed or embedded, and similarly, the second magnet 240 can also be exposed or embedded.

[0121] Multiple sets of magnets (e.g., 2-4 sets) can be set, each set of magnets includes a corresponding first magnet 140 and a second magnet 240. By dispersing the fixing force through multi-point magnetic attraction, the offset caused by insufficient magnetic force at a single point is avoided, which is especially suitable for large-size dust cup assembly 230 or heavy-duty handheld cleaning equipment 20.

[0122] In some embodiments, the position of the handheld cleaning device 20 relative to the base station 10 can be limited solely by the limiting member 1922. In other embodiments, the position of the handheld cleaning device 20 relative to the base station 10 can be limited solely by the first magnet 140 and the second magnet 240. In still other embodiments, the position of the handheld cleaning device 20 relative to the base station 10 can be limited by both the limiting member 1922 and the first magnet 140 and the second magnet 240, i.e., a combination of magnetic connection and mechanical limiting. If only mechanical limiting is relied upon (such as the sidewall of the cavity 1302), slight wobbling may occur due to gaps; if only magnetic connection is relied upon, insufficient fixing force may result from magnetic attenuation, or the cost may be too high; when the two are combined, mechanical limiting ensures approximate alignment, and magnetic connection eliminates gaps and provides continuous pre-tightening force, significantly improving the stability after docking. Through the above methods, the state of the handheld cleaning device 20 after docking with the base station 10 can be guaranteed to be stable and not easily tipped over.

[0123] In addition to fixing the handheld cleaning device 20 to the base station 10, the magnetic connection can also actively "pull" the handheld cleaning device 20 toward a precise position as the distance between the magnets decreases during the docking process of the handheld cleaning device 20 to the base station 10, reducing the number of times the user needs to manually adjust it (especially suitable for users with poor eyesight or who are not skilled in operation).

[0124] Please see Figure 11 , Figure 12 as well as Figure 13 . Figure 13 yes Figure 1 The cleaning system 100 shown is in a cross-sectional view in which the first conductor 150 and the second conductor 250 are in a docked state.

[0125] In some embodiments, the base station 10 also serves to charge the handheld cleaning device 20. To ensure that the handheld cleaning device 20 and the base station 10 are electrically connected simultaneously during the docking process, the following improvements are made.

[0126] Specifically, the base station 10 further includes a first conductor 150, which is disposed on the base station body 110. The handheld cleaning device 20 further includes a second conductor 250, which is disposed on the device body 220. When the handheld cleaning device 20 is connected to the base station 10, the first conductor 150 and the second conductor 250 are electrically connected, allowing the base station 10 to charge the handheld cleaning device 20. In some embodiments, when the first conductor 150 and the second conductor 250 are electrically connected, the first conductor 150 and the second conductor 250 may or may not be in contact.

[0127] Specifically, in Figure 1 In the cleaning system 100 shown, there are two first conductors 150, which are used to electrically connect to the positive and negative terminals of a power source, respectively. Correspondingly, there are two second conductors 250, which correspond one-to-one with the first conductors 150, and each second conductor 250 is used to electrically connect to its corresponding first conductor 150. The second conductors 250 are electrically connected to the power storage component (e.g., the battery in the main body 220, which supplies power to the main unit 223) in the handheld cleaning device 20.

[0128] Specifically, in Figure 1 In the cleaning system 100 shown, a first conductor 150 is disposed on a first housing 190 in the base station body 110 and is at least partially exposed to contact a second conductor 250. The first conductor 150 is disposed below a first mating surface 2312. Exemplarily, the second conductor 250 is disposed on a rod 221 in the body body 220 and is at least partially exposed to contact the first conductor 150. The second conductor 250 is disposed below a dust cup assembly 230.

[0129] In some embodiments, the first conductor 150 and the second conductor 250 may be made of copper or a copper alloy.

[0130] During the process of the handheld cleaning device 20 docking with the base station 10, the main body 220 rotates forward relative to the brush assembly 210 around the first axis L1, so that the second conductor 250 approaches the first conductor 150 in the circumferential direction F of the first axis L1 until it comes into contact.

[0131] To improve the contact effect between the first conductor 150 and the second conductor 250 and avoid poor contact, the following improvements are made.

[0132] In some embodiments, the first conductor 150 is horizontally floatably disposed on the base station body 110, and / or the second conductor 250 is horizontally floatably disposed on the fuselage body 220. "And / or" means: the first conductor 150 is horizontally floatably disposed on the base station body 110; or, the second conductor 250 is horizontally floatably disposed on the fuselage body 220; or, the first conductor 150 is horizontally floatably disposed on the base station body 110, and simultaneously, the second conductor 250 is horizontally floatably disposed on the fuselage body 220.

[0133] Since the first conductor 150 can be floated in the horizontal direction, when the second conductor 250 and the first conductor 150 come into contact in the horizontal direction, the first conductor 150 can adaptively adjust its position to achieve a better contact effect.

[0134] Similarly, since the second conductor 250 can be floated in the horizontal direction, when the second conductor 250 and the first conductor 150 come into contact in the horizontal direction, the second conductor 250 can adaptively adjust its position to achieve a better contact effect.

[0135] To enable the first conductor 150 to be horizontally floatable on the base station body 110, in some embodiments, the base station 10 further includes a first elastic member 161. The first conductor 150 is slidably fitted onto the base station body 110 in the horizontal direction, and the first elastic member 161 is held between the first conductor 150 and the base station body 110 in the horizontal direction. The first elastic member 161 is, for example, a spring.

[0136] In some other embodiments, the first conductor 150 may be designed to be elastic, allowing the portion of it that contacts the second conductor 250 to float.

[0137] To enable the second conductor 250 to be horizontally floatable on the main body 220, in some embodiments, the handheld cleaning device 20 further includes a second elastic element 162. The second conductor 250 slides horizontally on the main body 220, and the second elastic element 162 is held horizontally between the second conductor 250 and the main body 220. The second elastic element 162 is, for example, a spring.

[0138] In some other embodiments, the second conductor 250 may be designed to be elastic, allowing the portion of it that contacts the first conductor 150 to float.

[0139] Please see Figures 14 to 15 . Figure 14 yes Figure 1The cleaning system 100 shown is a three-dimensional cross-sectional view of the dust cup assembly 230, with the cup lid 232 in a closed state. Figure 15 yes Figure 1 The cleaning system 100 shown is a three-dimensional cross-sectional view of the dust cup assembly 230 installed behind the base station 10, with the cup lid 232 in the open state.

[0140] In some embodiments, the dust cup assembly 230 further includes a third elastic member 233. The third elastic member 233 is configured to apply a first elastic force to the cup lid 232 so that the cup lid 232 remains closed at the dust outlet 2311. The base station 10 also includes an opening member 170. The opening member 170 is disposed on the base station body 110 and is used to push the cup lid 232 against the first elastic force, thereby causing the cup lid 232 to open the dust outlet 2311.

[0141] When no external force is applied, the third elastic element 233 keeps the dust outlet 2311 in a normally closed state.

[0142] Specifically, the cup lid 232 is rotatably connected to the dust cup 231 about the second axis L2. The cup lid 232 has a sealing portion 2321 and a force-receiving portion 2322 located on both sides of the second axis L2. A third elastic member 233 is configured to apply a first elastic force to the force-receiving portion 2322. The force-receiving portion 2322 is used to rotate about the second axis L2 in a first direction F1 under the action of the first elastic force, thereby causing the cup lid 232 to close the dust outlet 2311. Specifically, the third elastic member 233 is a torsion spring.

[0143] Specifically, the cover opening component 170 is used to push against the force receiving part 2322 to overcome the first elastic force during the forward rotation of the main body 220 around the first axis L1, thereby causing the force receiving part 2322 to rotate around the second axis L2 in the second direction F2 opposite to the first direction F1, and then driving the cover part 2321 to rotate in the second direction F2, so that the cover part 2321 opens the dust outlet 2311.

[0144] During the docking of the handheld cleaning device 20 with the base station 10, the dust cup assembly 230 moves relative to the base station body 110, allowing the opening member 170 to push against the cup lid 232, thereby opening the dust outlet 2311 and connecting the dust outlet 2311 with the dust collection port 1102. When the dust cup assembly 230 separates from the base station body 110, the opening member 170 releases the force on the cup lid 232, and the cup lid 232 closes the dust outlet 2311 under the action of the third elastic member 233.

[0145] Please refer to the following: Figure 16 , Figure 16 yes Figure 1 The diagram shows a three-dimensional structure of the cleaning system 100, in which the locking element 235 is installed on the dust cup 231.

[0146] In some embodiments, the dust cup assembly 230 further includes a locking member 235 and a fourth elastic member 234, the locking member 235 being connected to the fourth elastic member 234. The locking member 235 is movably disposed in the dust cup 231. The locking member 235 has an unlocked state and a locked state. In the locked state, the locking member 235 is engaged with the cup lid 232, preventing the cup lid 232 from opening the dust outlet 2311. In the unlocked state, the locking member 235 is disengaged from the cup lid 232, allowing the cup lid 232 to open the dust outlet 2311 after rotation. The fourth elastic member 234 is configured to apply a second elastic force to the locking member 235 to keep the locking member 235 in the locked state.

[0147] By setting the locking fastener 235, the cup lid 232 can be prevented from accidentally opening the dust outlet 2311.

[0148] When the locking fastener 235 is provided, the base station 10 also includes an unlocking fastener 180. The unlocking fastener 180 is provided on the base station body 110. The unlocking fastener 180 is used to push the locking fastener 235 to overcome the second elastic force during the process of the body body 220 swinging forward around the first axis L1, thereby causing the locking fastener 235 to switch from the locked state to the unlocked state.

[0149] In some embodiments, the locking member 235 is rotatably connected to the dust cup 231 about a third axis L3. A fourth elastic member 234 is configured to apply a second elastic force to the locking member 235, causing the locking member 235 to rotate about the third axis L3 in a third direction F3, thereby engaging the locking member 235 with the cup lid 232. Specifically, the fourth elastic member 234 is a spring.

[0150] In other embodiments, the locking member 235 is connected to the fourth elastic member 234 and can move in a direction close to or away from the fourth elastic member 234. For example, the fourth elastic member 234 is arranged in a horizontal direction, and the locking member 235 can move in a horizontal direction. Exemplarily, when the locking member 235 is pressed under the action of an external force to overcome the second elastic force, the fourth elastic member 234 is compressed and stores force. At this time, the locking member 235 is unlocked from the cup lid 232, and the locking member 235 is in the unlocked state. If the external force disappears, the fourth elastic member 234 returns to its original position and drives the locking member 235 to return to its original position. At this time, the locking member 235 is locked from the cup lid 232. When the locking member 235 is in the unlocked state, the cup lid 232 remains closed at the dust outlet 2311 under the action of the third elastic member 233. The cup lid 232 can only open the dust outlet 2311 when the force of the third elastic member 233 is overcome.

[0151] Specifically, the unlocking component 180 is used to push the locking component 235 to overcome the second elastic force during the forward rotation of the main body 220 around the first axis L1, thereby causing the locking component 235 to rotate around the third axis L3 in the fourth direction F4 opposite to the third direction F3, and thus causing the locking component 235 to be disconnected from the cup lid 232.

[0152] During the process of the handheld cleaning device 20 connecting to the base station 10, the dust cup assembly 230 moves relative to the base station body 110, allowing the unlocking member 180 to push against the locking member 235, thereby disengaging the locking member 235 from the cup lid 232. Then, the opening member 170 pushes against the cup lid 232, causing the cup lid 232 to open the dust outlet 2311, thereby connecting the dust outlet 2311 with the dust collection port 1102.

[0153] In some embodiments, the unlocking member 180 may be a separate component disposed on the first housing 190 in the base station body 110, or disposed on the limiting member 1922 in the base station body 110. In other embodiments, the unlocking member 180 may also be part of the first housing 190 or part of the limiting member 1922.

[0154] After the handheld cleaning device 20 is connected to the base station 10, in order to improve the stability of the handheld cleaning device 20 on the base station 10 and prevent the handheld cleaning device 20 from falling off the base station 10, the following improvements are made.

[0155] Please see Figures 17 to 21 . Figure 17 This is a three-dimensional structural diagram of the handheld cleaning device 20 in a cleaning system 100 provided in an embodiment of the present disclosure. Figure 18 yes Figure 17 A magnified view of partial view E4. Figure 19 yes Figure 17 A three-dimensional structural diagram of the fastener 261 installed on the dust cup 231 in the handheld cleaning device 20 shown (only a part is shown). Figure 20 This is a three-dimensional structural schematic diagram of a base station 10 provided in an embodiment of this disclosure. Figure 21 yes Figure 20 A magnified view of partial view E5. Figure 17 The handheld cleaning device 20 shown is Figure 20 The base stations 10 shown work together.

[0156] In some embodiments, the dust cup assembly 230 further includes a retaining member 261 connected to the dust cup 231 in a first predetermined direction F5; the base station 10 further includes a blocking member 193 connected to the base station body 110 in the first predetermined direction F5, and used to block the retaining member 261 from moving relative to the blocking member 193 after the handheld cleaning device 20 is docked to the base station 10; one of the retaining member 261 and the blocking member 193 is connected to a fifth elastic member 262, which provides a force to hold the one connected thereto in a first position; during the docking of the handheld cleaning device 20 to the base station 10, the one of the retaining member 261 and the blocking member 193 connected to the fifth elastic member 262 moves to a second position under the pushing action of the other, and after avoiding the other, moves to the first position under the force of the fifth elastic member 262. It is understood that the dust cup assembly 230 and the base station 10 achieve docking and cooperation through a snap-fit ​​structure.

[0157] Exemplarily, the dust cup assembly 230 further includes a fifth elastic member 262. The fifth elastic member 262 is connected to the retaining member 261 so as to movably engage with the dust cup 231 in a first predetermined direction F5. The first predetermined direction F5 intersects with the front-rear direction. The fifth elastic member 262 is elastically clamped between the retaining member 261 and the dust cup 231 in the first predetermined direction F5. The blocking member 193 protrudes from the base station body 110 in the first predetermined direction F5.

[0158] Please refer to the following: Figures 22 to 24 . Figure 22 yes Figure 17 The handheld cleaning device 20 shown is connected to Figure 20 The diagram shows the process of the clamping member 261 and the blocking member 193 cooperating during the operation of the base station 10. Figure 23 yes Figure 17 The handheld cleaning device 20 shown is connected to Figure 20 A cross-sectional view of a partial structure of the cleaning system 100 after the base station 10 is shown. Figure 24 yes Figure 23 Sectional view of E6-E6.

[0159] During the process of docking the handheld cleaning device 20 to the base station 10, the fastener 261 and the blocking member 193 abut and slide together. Under the pushing action of the blocking member 193, the fastener 261, located in the first position, overcomes the elastic force of the fifth elastic member 262 and moves to the second position along the first predetermined direction F5 to avoid the fastener 261, and moves to the first position. This allows the fastener 261 to move from behind the blocking member 193 to in front of the blocking member 193. Taking the first predetermined direction F5 as the left and right direction as an example, the blocking member 193 is used to prevent the fastener 261 from moving backward after the handheld cleaning device 20 is docked to the base station 10, so as to prevent the handheld cleaning device 20 from falling off the base station 10.

[0160] Specifically, the first predetermined direction F5 is the left-right direction. In other embodiments, the first predetermined direction F5 can also be other directions, such as vertical. In this document, vertical is represented as up-down in the accompanying drawings.

[0161] Specifically, the fastener 261 is capable of reciprocating between a first position and a second position relative to the dust cup 231 in a first predetermined direction F5. Figure 22 In the diagram, part a indicates that the retaining member 261 is in the first position, located behind the blocking member 193, and at this time, the retaining member 261 has not yet contacted the blocking member 193; part b shows the retaining member 261 in the second position, located to the left or right of the blocking member 193, at which point the retaining member 261 contacts the blocking member 193 and compresses the fifth elastic member 262 under the abutment of the blocking member 193; part c shows the retaining member 261 in the first position, located in front of the blocking member 193, at which point the retaining member 261 has passed the blocking member 193 and returns to its original position under the action of the fifth elastic member 262. When the retaining member 261 is in the first position, the retaining member 261 and the blocking member 193 are arranged opposite each other in the front-back direction. When the retaining member 261 is in the second position, the retaining member 261 and the blocking member 193 are no longer arranged opposite each other in the front-back direction.

[0162] For example, the fifth elastic element 262 may be a spring or a rubber pad. The fifth elastic element 262 applies an elastic force to the fastener 261, so that the fastener 261 is in the first position without any other external force.

[0163] When the fastener 261 and the blocking member 193 come into contact, as the fastener 261 moves forward, the fastener 261 overcomes the elastic force of the fifth elastic member 262 under the pushing action of the blocking member 193, and moves forward and along the first predetermined direction F5, so that the fastener 261 switches from the first position to the second position.

[0164] During the process of the handheld cleaning device 20 docking with the base station 10, the movement of the fastener 261 is as follows: the fastener 261 moves forward under the drive of the dust cup 231, and under the action of the fifth elastic member 262, the fastener 261 is in the first position; when the fastener 261 abuts against the blocking member 193, as the fastener 261 moves forward, the fastener 261 moves along the first predetermined direction F5 at the same time, and gradually switches from the first position to the second position; as the fastener 261 continues to move forward, the fastener 261 separates from the blocking member 193, and when the fastener 261 moves in front of the blocking member 193, under the action of the fifth elastic member 262, the fastener 261 switches from the second position to the first position.

[0165] Specifically, there are two holding members 261, which are spaced apart in the first predetermined direction F5 and are capable of approaching and separating from each other. Correspondingly, there are two blocking members 193, which are spaced apart in the first predetermined direction F5. The blocking members 193 and the holding members 261 are in one-to-one correspondence. Each blocking member 193 is used to prevent the corresponding holding member 261 from moving backward after the handheld cleaning device 20 is docked to the base station 10.

[0166] In this embodiment, after the handheld cleaning device 20 is docked to the base station 10, a limiting cooperation structure in the front-to-back direction is formed between the fastener 261 and the blocking member 193, which reduces the probability of the handheld cleaning device 20 detaching from the base station 10 and improves the stability of the handheld cleaning device 20 on the base station 10.

[0167] Please continue reading. Figure 22 In some embodiments, the retaining member 261 has an abutment surface 2611. The abutment surface 2611 is disposed on the side of the retaining member 261 facing the blocking member 193, and is inclined relative to the front-back direction and the first predetermined direction F5, respectively. The blocking member 193 has an abutment portion 1931. During the process of the handheld cleaning device 20 docking with the base station 10, the abutment surface 2611 abuts and slides with the abutment portion 1931, thereby causing the retaining member 261 and the blocking member 193 to abut and slide.

[0168] In this embodiment, during the forward movement of the fastener 261, it abuts against the abutting portion 1931 of the blocking member 193. Guided by the abutting surface 2611, the fastener 261 moves forward and moves in the first predetermined direction F5.

[0169] Specifically, in the illustrated embodiment, the abutment portion 1931 is chamfered. When the abutment portion 1931 is chamfered, compared to the blocking member 193 abutting the abutment surface 2611 with a sharp corner, the resistance to relative sliding between the blocking member 193 and the abutment surface 2611 is reduced, making their sliding engagement smoother. In other embodiments, the abutment portion 1931 may also be a rounded chamfer or a beveled surface.

[0170] In some other embodiments (not shown), the abutment surface 2611 may be provided on the blocking member 193, and correspondingly, the abutment portion 1931 may be provided on the retaining member 261. In this embodiment, during forward movement, the retaining member 261 abuts against the abutment surface 2611 of the blocking member 193, and under the guidance of the abutment surface 2611, moves forward and moves in the first predetermined direction F5.

[0171] In some other embodiments (not shown), the retaining member 261 can be fixedly disposed on the dust cup 231, for example, the retaining member 261 can be protruding from the outer surface of the dust cup 231, while the blocking member 193 can be movably disposed on the base station body 110, for example, the fifth elastic member 262 can be connected to the blocking member 193. Specifically, the retaining member 261 protrudes from the dust cup 231 in the first predetermined direction F5, the blocking member 193 is movably engaged with the base station body 110 in the first predetermined direction F5, and the fifth elastic member 262 is elastically clamped between the blocking member 193 and the base station body 110 in the first predetermined direction F5. The docking process between the handheld cleaning device 20 and the base station 10 is similar to the above description and will not be repeated here.

[0172] Please continue reading. Figure 22 In some embodiments, in the first predetermined direction F5, the side of the abutment surface 2611 that is not connected to the dust cup 231 is disposed rearward relative to the side of the abutment surface 2611 that is connected to the dust cup 231.

[0173] The side of the contact surface 2611 that is not connected to the dust cup 231 is named the first side G1, and the side of the contact surface 2611 that is connected to the dust cup 231 is named the second side G2.

[0174] Specifically, when the first predetermined direction F5 is the left-right direction and the two fasteners 261 are set at left-right intervals: for the fastener 261 located on the left side, from right to left, the first side G1 gradually shifts towards the rear relative to the second side G2; for the fastener 261 located on the right side, from left to right, the first side G1 gradually shifts towards the rear relative to the second side G2.

[0175] For example, the two fasteners 261 are symmetrically arranged relative to the limiting hole 2316.

[0176] Please see Figure 21 and Figure 22In some embodiments, after the handheld cleaning device 20 is docked to the base station 10, the retaining member 261 is located in a predetermined area P1 of the base station body 110, and the base station body 110 is open upward at the predetermined area P1. It is understood that the area between the front of the blocking member 193 and the base station body 110 is unobstructed above the retaining member 261 to ensure that the retaining member 261 can move freely upward. The base station 10 is configured such that after the handheld cleaning device 20 is docked to the base station 10, the area above the retaining member 261 is unobstructed. Thus, when it is necessary to remove the handheld cleaning device 20 from the base station 10, the handheld cleaning device 20 can be slightly lifted upwards, and during the separation of the handheld cleaning device 20 from the base station 10, the limiting engagement relationship between the retaining member 261 and the blocking member 193 is released.

[0177] Specifically, since there are no structural components (such as baffles, protrusions, etc.) from the base station 10 obstructing the upper part of the holding member 261, the user only needs to apply an upward lifting force when he / she needs to remove the handheld cleaning device 20 from the base station 10. At this time, the handheld cleaning device 20 will move upward as a whole, and the limiting relationship between the holding member 261 and the blocking member 193 in the front-back direction will be naturally released as the handheld cleaning device 20 moves upward.

[0178] The advantage of this design is that it ensures the stability of the handheld cleaning device 20 after docking (preventing it from detaching backward) through the cooperation of the fastener 261 and the blocking member 193, while avoiding extra steps during separation (such as manually unlocking). Users do not need complicated operations; they can easily separate the handheld cleaning device 20 from the base station 10 by simply lifting it upward, an ergonomic action. Moreover, only a slight upward lift is needed to release the handheld cleaning device 20 from the base station 10, improving the user experience.

[0179] Please see Figure 20 , Figure 21 and Figure 23 In some embodiments, the base station body 110 further includes a limiting member 1922. The limiting member 1922 protrudes from the second mating surface 1101 and surrounds the dust collection port 1102, forming a top-open receiving cavity 1302. When the first mating surface 2312 abuts against the second mating surface 1101, the bottom of the dust cup assembly 230 is accommodated in the receiving cavity 1302. Specifically, the base station body 110 includes a first housing 190 and a second housing 192. The second housing 192 is disposed on the first housing 190 and located above the first housing 190. The second housing 192 includes a support member 1921 and a limiting member 1922. The top surface of the support member 1921 forms the aforementioned second mating surface 1101. The aforementioned dust collection port 1102 is opened on the support member 1921. The limiting member 1922 protrudes from the second mating surface 1101 of the support member 1921.

[0180] In this embodiment, the limiting member 1922 limits the dust cup assembly 230 around its bottom perimeter, allowing the handheld cleaning device 20 to be placed more stably on the base station 10. The above embodiments have been described in detail and will not be repeated here.

[0181] When the limiting member 1922 is provided, in order to make it easier for the dust cup assembly 230 to enter the receiving cavity 1302, the height of the rear end of the limiting member 1922 (the limiting part 1301) protruding from the second mating surface 1101 is usually low. This causes the dust cup assembly 230 to exit the receiving cavity 1302 from the rear end of the limiting member 1922.

[0182] In this embodiment, to further enhance the stability of the handheld cleaning device 20 on the base station 10, the blocking member 193 can be disposed within the receiving cavity 1302.

[0183] The above embodiments describe two methods for fixing and movably setting the blocking member 193. The specific methods for setting the blocking member 193 within the receiving cavity 1302 are described below.

[0184] like Figure 21 As shown, when the blocking member 193 is fixedly installed on the base station body 110, the blocking member 193 can protrude from the cavity wall of the accommodating cavity 1302 in the first predetermined direction F5. The blocking member 193 and the limiting member 1922 can be an integral structure or a separate structure.

[0185] When the blocking member 193 is movably disposed on the base station body 110 (not shown), it can be movably engaged with the limiting member 1922 in the first predetermined direction F5, and the fifth elastic member 262 is elastically clamped between the blocking member 193 and the limiting member 1922 in the first predetermined direction F5. At least a portion of the blocking member 193 is located within the receiving cavity 1302 to prevent the retaining member 261 from moving backward.

[0186] In some embodiments, the blocking member 193 is located in front of the dust collection port 1102. Since the plane containing the first mating surface 2312 and the plane containing the second mating surface 1101 are both inclined relative to the horizontal plane, the dust cup assembly 230 is at risk of flipping backward after the handheld cleaning device 20 is docked to the base station 10. By placing the blocking member 193 in front of the dust collection port 1102, the probability of the dust cup assembly 230 flipping backward is reduced to a greater extent compared to placing it behind the dust collection port 1102.

[0187] Please see Figure 23 and Figure 25 . Figure 25 yes Figure 23 Sectional view of E7-E7.

[0188] In some embodiments, the base station 10 further includes a connector 194, a sixth elastic member 195, and a driver 196. The connector 194 is movably disposed on the base station body 110 in a second predetermined direction F6, which intersects with the vertical direction. The sixth elastic member 195 is clamped between the connector 194 and the base station body 110 in the second predetermined direction F6. The driver 196 is disposed on the base station body 110. The dust cup 231 has a limiting hole 2316. After the handheld cleaning device 20 is docked to the base station 10, the opening 2317 of the limiting hole 2316 is disposed opposite to the connector 194 in the second predetermined direction F6. The driver 196 is used to drive the connector 194 to move to one side (near the limiting hole 2316) in the second predetermined direction F6, so that at least a portion of the connector 194 is inserted into the limiting hole 2316. The sixth elastic member 195 is used to drive the plug 194 to move in the second predetermined direction F6 toward the other side (away from the limiting hole 2316) so that at least a portion of the plug 194 is disengaged from the limiting hole 2316.

[0189] Specifically, the second predetermined direction F6 is the front-to-back direction. In other embodiments, the second predetermined direction F6 can also be other directions, such as the left-to-right direction.

[0190] Specifically, the limiting hole 2316 is a cylindrical hole extending in the second predetermined direction F6. The rear end of the connector 194 in the second predetermined direction F6 (the end facing the limiting hole 2316) is a cylindrical structure, and its shape and size are matched with the limiting hole 2316 so that after the rear end is inserted into the limiting hole 2316, there is a suitable gap between the rear end and the hole wall of the limiting hole 2316.

[0191] Specifically, the connector 194 is movable and engages with the base station body 110 in the second predetermined direction F6, and the connector 194 can be in the third position ( Figure 25 The connector 194 reciprocates between the third position (shown in the figure) and the fourth position (not shown). In the third position, the connector 194 is outside the limiting hole 2316. In the fourth position, at least a portion of the connector 194 is inside the limiting hole 2316.

[0192] Specifically, the sixth elastic element 195 can be a spring or a rubber component. Under the elastic force of the sixth elastic element 195, the connector 194 can move from the fourth position to the third position.

[0193] Specifically, the actuator 196 can be a motor. In other embodiments, the actuator 196 can also be a cylinder or a hydraulic cylinder. The actuator 196 can directly or indirectly drive the connector 194 to move in the second predetermined direction F6, as detailed below. The actuator 196 is capable of driving the connector 194 to overcome the elastic force of the sixth elastic member 195 and switch from the third position to the fourth position.

[0194] After the handheld cleaning device 20 is connected to the base station 10, the opening 2317 of the limiting hole 2316 is positioned opposite the connector 194 in the second predetermined direction F6. The driver 196 drives the connector 194 to move, causing at least a portion of the connector 194 to insert into the limiting hole 2316, thereby preventing the dust cup assembly 230 from moving upward relative to the base station 10. When the driver 196 releases the driving force on the connector 194, the sixth elastic member 195 drives the connector 194 to reset, causing at least a portion of the connector 194 to exit the limiting hole 2316, thereby releasing the limiting effect of the connector 194 on the dust cup assembly 230, and thus enabling the handheld cleaning device 20 to be separated from the base station 10.

[0195] In this embodiment, by providing the connector 194, the dust cup assembly 230 can be limited at least vertically, thereby improving the stability of the handheld cleaning device 20 on the base station 10.

[0196] Please see Figures 26 to 28 . Figure 26 yes Figure 20 The diagram shows a three-dimensional structural schematic of the connector 194 installation location in the base station 10 from a first-view perspective. Only a portion of the base station body 110 is shown. Figure 27 yes Figure 20 The diagram shows a three-dimensional structure of the connector 194 in the base station 10 from a second perspective. Only a portion of the base station body 110 is shown. Figure 28 yes Figure 20 The diagram shows a three-dimensional structure of the connector 194 installation location in the base station 10, omitting the base station body 110.

[0197] In some embodiments, the driver 196 indirectly drives the connector 194 via a transmission component, as detailed below.

[0198] The base station 10 also includes a first transmission member 197 and a second transmission member 198. The first transmission member 197 is movably disposed on the base station body 110 and connected to the driver 196; the second transmission member 198 is movably fitted to the base station body 110 and is respectively in transmission engagement with the first transmission member 197 and the connector 194; wherein, when the driver 196 drives the first transmission member 197 to move, the first transmission member 197 drives the second transmission member 198 to move, and the second transmission member 198 drives the connector 194 to move, so that the connector 194 inserts into or exits the limiting hole 2316.

[0199] Exemplarily, a first transmission member 197 is rotatably disposed on the base station body 110 with the vertical axis as its axis. A second transmission member 198 is movably fitted to the base station body 110 in a vertical direction. The second transmission member 198 is in a transmission engagement with the first transmission member 197, such that the rotational motion of the first transmission member 197 can be converted into the linear motion of the second transmission member 198. The second transmission member 198 is in a transmission engagement with the connector 194, such that the linear motion of the second transmission member 198 in the vertical direction is converted into the motion of the connector 194 in a second predetermined direction F6. The driver 196 is used to drive the first transmission member 197 to rotate, thereby driving the connector 194 to move in the second predetermined direction F6.

[0200] Specifically, the first transmission component 197 is a lead screw, and a portion of the second transmission component 198 is sleeved outside the first transmission component 197, engaging with the first transmission component 197 in a helical transmission manner to convert the rotational motion of the lead screw into the vertical linear motion of the second transmission component 198. For example, when the lead screw rotates clockwise, the second transmission component 198 moves upward, and when the lead screw rotates counterclockwise, the second transmission component 198 moves downward.

[0201] In one application scenario, the driver 196 drives the first transmission member 197 to rotate forward. The first transmission member 197 drives the second transmission member 198 to move upward. The second transmission member 198 drives the plug-in member 194 to overcome the elastic force of the sixth elastic member 195 and move in the second predetermined direction F6, moving from the third position to the fourth position, so that at least a portion of the plug-in member 194 is inserted into the limiting hole 2316, thereby forming a limiting engagement structure between the plug-in member 194 and the dust cup assembly 230. The driver 196 drives the first transmission member 197 to rotate in reverse. The first transmission member 197 drives the second transmission member 198 to move downward. Under the action of the sixth elastic member 195, the plug-in member 194 moves in the second predetermined direction F6 and moves from the fourth position to the third position, causing the plug-in member 194 to exit the limiting hole 2316, thereby releasing the limiting engagement structure between the plug-in member 194 and the dust cup assembly 230. Taking the second predetermined direction F6 as the front-to-back direction as an example, the connector 194 moves from front to back to move from the third position to the fourth position, so that at least a portion of the connector 194 is inserted into the limiting hole 2316; or, the connector 194 moves from back to front to move from the fourth position to the third position, so that the connector 194 exits the limiting hole 2316.

[0202] In this embodiment, by setting the first transmission member 197 and the second transmission member 198, there are more options for the setting position of the driver 196 and the connector 194 on the base station body 110.

[0203] See Figure 28 and 29In some embodiments, the connector 194 includes a plug-in portion 194a and a mating portion 194b. The plug-in portion 194a protrudes from the outer periphery of the mating portion 194b and extends in a direction away from the sixth elastic member 195. The mating portion 194b includes a through portion 1940 and a support portion 1943 connected to the through portion 1940. The through portion 1940 is provided with a first through hole 1942 for the second transmission member 198 to pass through. The support portion 1943 is connected to one end of the sixth elastic member 195.

[0204] Specifically, the insertion portion 194a is disposed on the side wall of the mating portion 194b away from the sixth elastic member 195, that is, on the side wall of the penetrating portion 1940, so that the insertion portion 194a is closer to the limiting hole 2316 relative to the mating portion 194b. The opening direction of the first through hole 1942 is consistent with the extension direction of the second transmission member 198, so as to facilitate the second transmission member 198 to pass through during movement. For example, the opening direction of the first through hole 1942 is perpendicular to the second predetermined direction F6. The support portion 1943 is connected to one end of the sixth elastic member 195. When the support portion 1943 is not subjected to external force, it can be driven to move by the sixth elastic member 195. For example, taking the second predetermined direction F6 as the front-back direction, the insertion portion 194a is disposed on the rear side wall of the mating portion 194b, that is, on the rear side wall of the penetrating portion 1940, and extends rearward; the sixth elastic member 195 is disposed in the front-back direction. The support sub-part 1943 can be disposed above the through sub-part 1940 and extend in the vertical direction; the through sub-part 1940 is disposed in the front-back direction, and the opening direction of the first through hole 1942 is the vertical direction.

[0205] See Figures 26 to 28 In some embodiments, the base station body 110 is further provided with a second through hole 1109 and a movable member 1110. The position of the second through hole 1110 is opposite to the position of the plug-in part 194a, so that the plug-in part 194a can pass through when it moves in the second predetermined direction F6 toward the direction close to the limiting hole 2316. The sixth elastic member 195 is sleeved on the movable member 1110, and one end of the movable member 1110 is connected to the other end of the sixth elastic member 195. The support sub-part 1943 is provided with a third through hole 1944. When the plug-in part 194a moves in the second predetermined direction F6 toward the direction close to the limiting hole 2316, the third through hole 1944 is used for the other end of the movable member 1110 to pass through.

[0206] Specifically, the second through hole 1109, the insertion part 194a, and the limiting hole 2316 are positioned opposite each other to ensure that the insertion part 194a can pass through the second through hole 1109 and then be inserted into the limiting hole 2316. The movable member 1110 can extend along the second predetermined direction F6, and the sixth elastic member 195 is sleeved on the movable member 1110 and also extends along the second predetermined direction F6. The opening direction of the third through hole 1944 is consistent with the extension direction of the movable member 1110 to facilitate the movable member 1110 to pass through during movement. For example, taking the second predetermined direction F6 as the front-rear direction, the front end of the sixth elastic member 195 is connected to the support sub-part 1943, the rear end of the sixth elastic member 195 is connected to the rear end of the movable member 1110, and the front end of the movable member 1110 can pass through the third through hole 1944.

[0207] Please refer to the following: Figure 29 . Figure 29 yes Figure 23 A magnified view of partial view E8.

[0208] In some embodiments, the second transmission member 198 has a first transmission mating surface 1981, which is inclined relative to the vertical direction and the second predetermined direction F6. The mating part 194b has a second transmission mating surface 1941, which is used to abut and slide against the first transmission mating surface 1981, thereby enabling the second transmission member 198 to drive into contact with the plug-in member 194. Exemplarily, the second predetermined direction F6 is the front-rear direction, and the first transmission mating surface 1981 is disposed on the side wall of the second transmission member 198 facing the limiting hole 2316. In the vertical direction (i.e., the up-down direction), the upper side of the first transmission mating surface 1981 is ( Figure 29 G3 in the middle is located on the lower side of the first transmission mating surface 1981. Figure 29 The G4 in the first through hole 1942 is positioned facing forward; the second transmission mating surface 1941 is located on the side wall of the first through hole 1942 near the insertion part 194a. In the vertical direction, the upper side of the second transmission mating surface 1941 is positioned facing forward relative to the lower side of the first transmission mating surface 1941.

[0209] Specifically, in the illustrated embodiment, after the first transmission mating surface 1981 enters the first through hole 1942, it contacts the inner wall surface of the first through hole 1942 to form a transmission mating structure. The rear sidewall edge of the first through hole 1942 forms the second transmission mating surface 1941. In the illustrated embodiment, the second transmission mating surface 1941 is chamfered. With the second transmission mating surface 1941 chamfered, compared to the connector 194 abutting against the first transmission mating surface 1981 through a sharp corner, the resistance to relative sliding between the connector 194 and the first transmission mating surface 1981 can be reduced. In other embodiments, the second transmission mating surface 1941 can also be a rounded chamfer or a beveled surface.

[0210] In some embodiments, the base station 10 further includes a detection component 1990, which is disposed on the base station body 110 for detecting the movement position of at least one of the first transmission member 197 and the second transmission member 198. Specifically, since the first transmission member 197 can drive the second transmission member 198 and the pusher member 199 to move, the detection component 1990 can infer the position of the other two as long as it detects the movement position of any one of the first transmission member 197, the second transmission member 198, and the pusher member 199. Therefore, the detection component 1990 can detect the movement position of any one of the first transmission member 197, the second transmission member 198, and the pusher member 199.

[0211] For example, when the first transmission member 197 drives the second transmission member 198 and the pushing member 199 to move vertically, the detection component 1990 can be disposed on either side of the first transmission member 197 in the vertical direction. The detection component 1990 can be disposed on the upper or lower side of the first transmission member 197, thereby detecting the upper or lower limit position of the first transmission member 197 during its vertical movement. For example, the detection component 1990 can be a micro switch, with two micro switches respectively disposed on the upper and lower sides of the first transmission member 197, thereby controlling the limit position of the first transmission member 197 in the vertical direction.

[0212] In another exemplary embodiment, when the first transmission member 197 drives the second transmission member 198 and the pushing member 199 to move vertically through rotational motion, the detection component 1990 can be set on either side of the second transmission member 198 or the pushing member 199 in the vertical direction. The specific setting method is similar to the above description and will not be repeated here. The detection component 1990 can be set on the upper side or the lower side of the second transmission member 198 or the pushing member 199.

[0213] It should be noted that the upper or lower side described above can be directly above or directly below, or it can be not directly above or directly below. For example, it can be obliquely above or obliquely below. The detection component 1990 can be set directly above or directly below other structures connected to the second transmission member 198 or the pushing member 199. The movement position of the second transmission member 198 or the pushing member 199 can also be inferred from these other structures.

[0214] Please see Figure 30 . Figure 30 yes Figure 17 The handheld cleaning device 20 shown is connected to Figure 20 The diagram shows the arrangement of the pusher 199 and the movable member 263 relative to each other behind the base station 10. Figure 31 This is a partial structural cross-sectional view of the handheld cleaning device 20 and the base station 10.

[0215] In some embodiments, the dust cup assembly 230 further includes a movable member 263, which is vertically movably disposed on the dust cup 231. The base station 10 also includes a pusher 199, which is vertically movably disposed on the base station body 110. After the handheld cleaning device 20 is docked to the base station 10, the pusher 199 is located below the movable member 263 and is vertically opposite to the movable member 263. The pusher 199 is connected to the second transmission member 198. As the pusher 199 moves upward with the second transmission member 198, it can push against the movable member 263, thereby driving the movable member 263 to move upward. That is, under the drive of the first transmission member 197, the pusher 199 and the second transmission member 198 can move upward or downward synchronously.

[0216] In some embodiments, the dust cup 231 is provided with a filter element 265, which is connected to the suction device of the handheld cleaning device 20. After air passes through the filter element 265, dust and other debris are retained inside the dust cup 231. Exemplarily, the filter element 265 can be a cylindrical metal mesh. A scraper element 264 is disposed outside the filter element 265. For example, the scraper element 264 can be a ring, fitted around the outer periphery of the filter element 265, abutting against the outer periphery of the filter element 265, or it can abut against the inner wall of the dust cup 231. The scraper element 264 can effectively scrape off dust and other debris adhering to or adsorbed on the filter element 265 or the dust cup 231, ensuring the cleanliness of the dust cup 231.

[0217] In one application scenario, the movable part 263 is used to drive the scraper part 264 in the dust cup 231 (see...). Figure 31The moving part 263 moves vertically back and forth, causing the scraper 264 to scrape dust from the outer wall of the filter element 265 or the inner wall of the dust cup 231, so that the dust falls into the dust cup 231. Of course, in other application scenarios, the moving part 263 can also have other functions. For example, pushing the moving part 263 upward will cause the scraper 264 to move downward; or pushing the moving part 263 downward will cause the scraper 264 to move upward. Of course, the operation mode of the moving part 263 and the scraper 264 can also be in other forms, and this disclosure does not limit them.

[0218] After the handheld cleaning device 20 is connected to the base station 10, the base station 10 activates the dust collection mode to collect the debris in the dust cup 231 into the dust collection container 120 of the base station 10. In one application scenario, the base station 10 will automatically activate the dust collection mode after a predetermined dust collection condition is met. In another application scenario, the user can also actively trigger the base station 10 to activate the dust collection mode. For example, the base station 10 is equipped with a button 1111 to trigger dust collection (see...). Figure 21 The user can press button 1111 to activate the dust collection mode of base station 10. Button 1111 can be located on the top shell of base station body 110.

[0219] In dust collection mode, the driver 196 actuates, driving the pusher 199 and the second transmission member 198 to reciprocate vertically in sync. As the pusher 199 moves upward following the second transmission member 198, it pushes against the movable member 263, thereby causing the movable member 263 to move upward. The movable member 263 can be driven downward by other components within the dust cup 231 (e.g., an elastic element). Thus, the movable member 263 can reciprocate vertically, allowing the scraper 264 to scrape dust from the dust cup 231.

[0220] During the process of pushing the movable part 263 upward by the pusher 199, an upward force may be exerted on the dust cup assembly 230, thereby causing the dust cup assembly 230 to separate from the base station 10.

[0221] In this embodiment, the second transmission member 198 and the pushing member 199 move synchronously. When the pushing member 199 pushes the movable member 263 upward, at least a portion of the plug member 194 is inserted into the limiting hole 2316 under the action of the second transmission member 198, thus restricting the upward movement of the dust cup assembly 230. Therefore, in this embodiment, when the driver 196 drives the movable member 263 to move upward, the risk of the dust cup assembly 230 detaching from the base station 10 is reduced.

[0222] Furthermore, the dust collection mode is configured such that when the driver 196 stops working, the connector 194 exits the limiting hole 2316, so that the handheld cleaning device 20 can be removed from the base station 10 after the dust collection mode ends.

[0223] Specifically, during the operation of the driver 196, the initial and final positions of the second transmission member 198 in the vertical direction are the same, both being the lowest position in the vertical direction. When the second transmission member 198 is at this lowest position, the connector 194 is located outside the limiting hole 2316. Similarly, during the operation of the driver 196, the initial and final positions of the pusher member 199 in the vertical direction are the same, both being the lowest position in the vertical direction. When the pusher member 199 is at this lowest position, it will not affect the docking of the handheld cleaning device 20 to the base station 10.

[0224] In the embodiments of this disclosure, when a user cleans the surface S1 to be cleaned with the handheld cleaning device 20, they generally apply force by gripping the handle 222, pushing forward or pulling back to drive the walking wheel 202 to roll forward or backward respectively, thereby driving the floor brush assembly 210 to move forward or backward. During the forward or backward movement of the floor brush assembly 210, the roller brush 212 rolls and drags on the surface S1 to be cleaned, and the fan set in the main unit draws air. The two work together to collect the debris on the surface S1 to be cleaned into the dust cup 231. When the cleaning task is completed or paused, and the user wants to return the handheld cleaning device 20 to the base station 10, such as for dust collection or charging, the user does not need to change the grip position and action. The user can continue to grip the handle 222 in the same grip position and pushing direction as when performing the cleaning task, and push the handheld cleaning device 20 toward the base station 10. The floor brush assembly 210 moves under the drive of the walking wheel 202 until it reaches the receiving cavity 1103 of the base station 10. Then, the user can stop controlling the walking wheel 202 and the floor brush assembly 210 to move forward, and instead push the main body 220 forward, so that the main body 220 rotates forward relative to the floor brush assembly 210, so that the first mating surface 2312 and the second mating surface 1101 slide and abut against each other. At this time, the docking work between the handheld cleaning device 20 and the base station 10 is completed. In the process of placing the handheld cleaning device 20 back into the base station 10, this disclosure fully utilizes the cooperation between the wheel assembly 200, the first mating surface 2312, and the second mating surface 1101, solving the problem of the effort required to carry it by hand in the prior art without utilizing wheels. During the movement of the floor brush assembly 210 to the base station 10, the pushing force of the wheel assembly 200 and the sliding cooperation between the first mating surface 2312 and the second mating surface 1101 are used to achieve docking with only a small pushing force, greatly reducing the operational burden. Moreover, the docking process is smoother and more efficient. After cleaning, the user does not need to change its original grip position or perform any actions, nor does it need to make large movements or exert more force, saving time and effort and making operation simple. Furthermore, the state after docking is stable and not easy to tip over.
