[0038] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0039] It should be noted that when an element is referred to as being "fixed to" or "set on" another element, it can be directly or indirectly on that other element. When an element is referred to as being "connected to" another element, it can be directly or indirectly connected to that other element. Unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0040] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0041] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0042] As described in the background section, current cleaning equipment, such as floor scrubbers and vacuum cleaners, typically uses a handle structure for users to hold and operate. However, in some existing cleaning equipment, when in a flat working position, the handle comes into direct contact with the ground, causing handle wear and increased pushing resistance, which affects the handle's lifespan and the user experience.

[0043] See Figure 1 and Figures 6 to 9 As shown, in order to solve the above problems, according to one aspect of this application, an embodiment of this application provides a handle device connected to the device body 30 of a cleaning device. The cleaning device includes a device body 30 and a cleaning seat 40, which are hinged together. The cleaning seat 40 is movable on the surface to be cleaned. The handle device includes a handle portion 10 and a roller portion 20. The handle portion 10 is installed at the end of the device body 30 away from the cleaning seat 40. The roller portion 20 is rotatably installed on the handle portion 10, and the rotation axis of the roller portion 20 is parallel to the hinge axis of the device body 30. The device body 30 has a first working position and a second working position. When the device body 30 is in the first working position, the device body 30 is upright relative to the cleaning seat 40, and the roller portion 20 is separated from the surface to be cleaned. When the device body 30 is in the second working position, the device body 30 is flat relative to the cleaning seat 40, and the handle portion 10 forms a load-bearing rolling contact with the surface to be cleaned through the roller portion 20. The handle device provided in this embodiment rotatably mounts the roller part 20 to the handle part 10, and makes the rotation axis of the roller part 20 parallel to the hinge axis of the device body 30. This allows the handle part 10 to form a load-bearing rolling contact with the surface to be cleaned through the roller part 20 when the device body 30 is in the second working position. This transforms the traditional sliding friction into rolling friction, extending the service life of the handle device. At the same time, it significantly reduces the operating resistance of the handle device, making the push of the handle device more effortless and smooth, and effectively improving the user experience.

[0044] It should be noted that, in this embodiment, the handle device refers to the mechanical component connected to the main body 30 of the cleaning device and operated by the user; the cleaning seat 40 refers to the moving part that directly contacts the surface to be cleaned and performs the cleaning function; the roller part 20 refers to the circular rolling member that can rotate around a fixed axis, and its rotation axis specifically refers to the central axis of the roller's rotational movement; the load-bearing rolling contact refers to the rolling friction fit relationship formed between the roller part 20 and the surface to be cleaned when bearing the vertical load transmitted by the handle part 10.

[0045] It is understood that the first working position in this embodiment refers to the working position in which the device body 30 is in an upright state relative to the cleaning seat 40, and the second working position refers to the working position in which the device body 30 is in a horizontal state relative to the cleaning seat 40. Furthermore, in other embodiments, the device body 30 and the cleaning seat 40 in this embodiment may also be connected by equivalent movable connection structures that allow relative swinging, other than hinges. When a non-fixed axis connection is used, the rotational motion of the device body 30 relative to the cleaning seat 40 during swinging can be equivalent to rotation about a virtual hinge axis, which is determined by the instantaneous motion trajectory during the swinging process.

[0046] In some specific embodiments, the handle portion 10 in this embodiment includes a handle body 11 and a telescopic rod assembly 12. The handle body 11 is connected to a first end of the telescopic rod assembly 12, and the second end of the telescopic rod assembly 12 is connected to the device body 30. The extension and retraction of the telescopic rod assembly 12 is used to change the relative distance between the handle body 11 and the device body 30 along the axial direction of the telescopic rod assembly 12. It should be noted that, in this embodiment, the handle body 11 refers to the gripping part of the handle device that directly contacts the user's palm; the telescopic rod assembly 12 refers to an adjustable-length connecting rod, and its axial direction specifically refers to the length extension direction of the telescopic rod assembly 12; the relative distance between the handle body 11 and the device body 30 along the axial direction of the telescopic rod assembly 12 refers to the adjustable distance between the handle body 11 and the device body 30 along the axial direction of the telescopic rod assembly 12.

[0047] In some embodiments, the telescopic rod assembly 12 in this embodiment has an axial telescopic adjustment range of 0–200 mm. Of course, in other embodiments, the axial telescopic adjustment range of the telescopic rod assembly 12 in this embodiment can also be other sizes.

[0048] It is understood that the handle device in this embodiment allows users to flexibly adjust the length of the handle device according to their height and usage habits through the axial telescopic movement of the telescopic rod assembly 12, thereby obtaining the best operating posture and solving the technical problem that traditional fixed-length handles cannot be adapted to different user groups.

[0049] In some embodiments, the telescopic rod assembly 12 in this embodiment is a hollow component. By setting the telescopic rod assembly 12 as a hollow component, the handle device can be wired inside the telescopic rod assembly 12, which helps to improve the structural compactness of the handle device.

[0050] See Figures 1 to 3 As shown, in some specific embodiments, the handle portion 10 in this embodiment further includes a fixed rod assembly 13. The second end of the telescopic rod assembly 12 is rotatably mounted on the first end of the fixed rod assembly 13, and the second end of the fixed rod assembly 13 is connected to the device body 30. The rotation axis between the telescopic rod assembly 12 and the fixed rod assembly 13 is perpendicular to the axis of the fixed rod assembly 13 and parallel to the hinge axis of the device body 30. It should be noted that in this embodiment, the fixed rod assembly 13 refers to a rigid support structure fixedly connected to the device body 30; the rotation axis between the telescopic rod assembly 12 and the fixed rod assembly 13 specifically refers to the central axis of the rotational movement of the telescopic rod assembly 12 relative to the fixed rod assembly 13.

[0051] In some embodiments, the fixing rod assembly 13 in this embodiment is a hollow component. By setting the fixing rod assembly 13 as a hollow component, the handle device can be wired inside the fixing rod assembly 13, which is beneficial to improving the structural compactness of the handle device.

[0052] It is understood that the handle device in this embodiment is rotatably connected to the telescopic rod assembly 12 via the fixed rod assembly 13, which enables the handle part 10 to be flexibly adjusted with multiple degrees of freedom. The axial extension and retraction of the telescopic rod assembly 12 can provide the handle part 10 with a length adjustment function, and the rotational movement around the fixed rod assembly 13 can optimize the working angle of the handle part 10, so that the handle part 10 can adapt to different cleaning postures. Setting the rotation axis between the telescopic rod assembly 12 and the fixed rod assembly 13 to be parallel to the hinge axis of the equipment can ensure the coordination of the movement of the handle part 10 and avoid uneven wear or jamming.

[0053] See Figures 6 to 9As shown, in some specific embodiments, the telescopic rod assembly 12 in this embodiment has a first position, a second position, and a third position relative to the fixed rod assembly 13. When the device body 30 is in the second working position, the side of the device body 30 closer to the surface to be cleaned is the first side of the device body 30, and the side away from the surface to be cleaned is the second side of the device body 30. When the telescopic rod assembly 12 is in the first position, the axis of the telescopic rod assembly 12 is collinear with the axis of the fixed rod assembly 13. When the telescopic rod assembly 12 is in the second position, the telescopic rod assembly 12 rotates from the first position along the first direction by a first preset angle, so that the telescopic rod assembly 12 is folded and stored in the first side of the device body 30. When the telescopic rod assembly 12 is in the third position, the telescopic rod assembly 12 rotates from the first position along the second direction by a second preset angle, so that the telescopic rod assembly 12 is at least partially located on the second side of the device body 30. The direction from the first side of the device body 30 to the second side of the device body 30 is the first direction, and the second direction is opposite to the first direction. It should be noted that, in this embodiment, the first position refers to the reference position where the axes of the telescopic rod assembly 12 and the fixed rod assembly 13 are collinear; the second position is the folded storage state after the telescopic rod assembly 12 rotates from the first position around its rotation axis in the first direction by a preset angle; and the third position is the unfolded working state after rotating from the first position in the opposite second direction.

[0054] See Figure 8 As shown, in some embodiments, the first preset angle in this embodiment is 180°. By setting the first preset angle to 180°, the telescopic rod assembly 12 can be parallel to the fixed rod assembly 13 after being flipped, which helps to reduce the space occupied by the handle part 10 in the lateral direction of the cleaning device. Of course, in other embodiments, the first preset angle in this embodiment can also be other angles, such as 175° to 185°.

[0055] See Figure 9 As shown, in some embodiments, the second preset angle in this embodiment is 90°. By setting the second preset angle to 90°, the handle body 11 can be in a better operating position after the telescopic rod assembly 12 is extended, making it easier for the user to apply force to the handle body 11 while standing, reducing user fatigue. At the same time, setting the second preset angle to 90° can also form a stable right-angle support structure between the telescopic rod assembly 12 and the fixed rod assembly 13, which is beneficial for dispersing torsional stress during cleaning operations. Of course, in other embodiments, the second preset angle in this embodiment can also be other angles, such as 85° to 90°.

[0056] In some embodiments, when the device body 30 is in the first working position, the telescopic rod assembly 12 is set to the first position, and the height of the handle body 11 can be adjusted by the extension and retraction of the telescopic rod assembly 12, so that the user can hold the handle device. When the telescopic rod assembly 12 is set to the second position, the handle device can be folded and stored on the first side of the device body 30. At this time, the space occupied by the handle device and the device body 30 in the height direction of the cleaning device at least partially overlaps, so as to facilitate the storage of the cleaning device. When the device body 30 is in the second working position, the telescopic rod assembly 12 is set to the third position, so that the handle device has a higher spatial position relative to the cleaning device, so that the user can hold the handle device in a standing posture and push the cleaning device to clean.

[0057] See Figures 3 to 5 As shown, in some specific embodiments, the handle device in this embodiment further includes a locking assembly 14, which is slidably mounted on the fixed rod assembly 13. The locking assembly 14 has a first locked state and a first unlocked state. When the locking assembly 14 is in the first locked state, it locks into the telescopic rod assembly 12, so that the telescopic rod assembly 12 maintains a first position, a second position, or a third position. When the locking assembly 14 is in the first unlocked state, it separates from the telescopic rod assembly 12, so that the telescopic rod assembly 12 can rotate freely relative to the fixed rod assembly 13. By locking the locking assembly 14 and the telescopic rod assembly 12 in the first locked state, reliable locking of the telescopic rod assembly 12 in three working positions can be ensured, preventing accidental displacement of the telescopic rod assembly 12 during the cleaning operation of the cleaning device. By setting the locking assembly 14 to be separated from the telescopic rod assembly 12 in the first unlocked state, the telescopic rod assembly 12 can rotate freely relative to the fixed rod assembly 13, thereby quickly switching between the three working positions.

[0058] In some embodiments, the fixing rod assembly 13 includes an inner fixing rod 131 and an outer fixing rod 132. The first end of the inner fixing rod 131 is connected to the second end of the telescopic assembly. The second end of the inner fixing rod 131 passes through the first end of the outer fixing rod 132 and is fixedly connected to it. The second end of the outer fixing rod 132 is fixedly connected to the device body 30. The nested connection structure of the inner fixing rod 131 and the outer fixing rod 132 improves the structural strength and bending resistance of the fixing rod assembly 13.

[0059] In some embodiments, the fixing rod assembly 13 is provided with a mounting shaft 13122. The locking assembly 14 in this embodiment includes a locking body 141, which is provided with a first mounting hole. The locking body 141 is slidably mounted on the fixing rod assembly 13 along the axial direction of the mounting shaft 13122 through the cooperation of the first mounting hole and the mounting shaft 13122. The axis of the mounting shaft 13122 is parallel to the pivot axis of the device body 30. By setting the axis of the mounting shaft 13122 of the locking body 141 to be parallel to the pivot axis of the device body 30, it can be ensured that the locking assembly 14 is subjected to uniform force during operation and jamming can be avoided.

[0060] In some embodiments, the inner wall of the first mounting hole in this embodiment is provided with a first limiting groove extending axially therefrom, and the outer wall of the mounting shaft 13122 is provided with a first limiting rib extending axially therefrom. In this embodiment, the first limiting rib is adapted to the first limiting groove, and the first limiting rib is slidably inserted into the first limiting groove. The cooperation between the first limiting rib and the first limiting groove can effectively prevent the locking body 141 from rotating around the axis of the mounting shaft 13122. Through the axial sliding cooperation between the first limiting rib and the first limiting groove, it can be ensured that the locking body 141 slides smoothly along the mounting shaft 13122 while preventing the locking body 141 from rotating around the mounting shaft 13122. This maintains the linear motion accuracy of the locking and unlocking operations and avoids positioning failure caused by accidental torsion, significantly improving the working reliability and service life of the locking assembly 14.

[0061] In some embodiments, there are multiple first limiting grooves and multiple first limiting ribs in this embodiment. Multiple first limiting ribs are arranged at intervals along the circumferential direction of the mounting shaft 13122. Multiple first limiting grooves correspond one-to-one with multiple first limiting ribs. Through the cooperation of multiple sets of first limiting grooves and first limiting ribs, multiple points of locking body 141 can be limited, further avoiding positioning failure of locking body 141 due to accidental torsion.

[0062] In some embodiments, the fixing rod assembly 13 of this embodiment is provided with a receiving hole 13121. The mounting shaft 13122 of this embodiment is disposed in the receiving hole 13121 and is coaxially disposed with the receiving hole 13121. The locking body 141 is at least partially inserted into the receiving hole 13121 through sliding cooperation with the mounting shaft 13122. A second limiting rib 1411 is provided on the outer side wall of the locking body 141, and a second limiting groove 131211 is provided on the inner side wall of the receiving hole 13121. In this embodiment, the second limiting rib 1411 is adapted to the second limiting groove 131211, and the second limiting rib 1411 is slidably inserted into the second limiting groove 131211. The cooperation between the second limiting rib 1411 and the second limiting groove 131211 can effectively prevent the locking body 141 from rotating around the axis of the receiving hole 13121. By axially sliding the second limiting rib 1411 with the second limiting groove 131211, it is possible to ensure that the locking body 141 slides smoothly along the receiving hole 13121 while preventing the locking body 141 from rotating around the receiving hole 13121. This maintains the linear motion accuracy of the locking and unlocking operations and avoids positioning failure caused by accidental torsion, significantly improving the working reliability and service life of the locking assembly 14.

[0063] In some embodiments, the second end of the telescopic rod assembly 12 in this embodiment is connected to the first end of the fixed rod assembly 13 via the locking body 141; a second mounting hole 1221 is provided on the second end of the telescopic rod assembly 12, and a third limiting groove 12211 is provided on the inner sidewall of the second mounting hole 1221. The third limiting groove 12211 is adapted to the second limiting rib 1411, and the position of the third limiting groove 12211 corresponds to the position of the second limiting rib 1411. The locking body 141 has an axial clearance section 1412 without the second limiting rib 1411. When the locking assembly 14 is in the first unlocked state... In the first locked state, the second limiting rib 1411 is separated from the third limiting groove 12211, and the second mounting hole 1221 corresponds to the clearance section 1412 of the locking body 141. At this time, the telescopic rod assembly 12 can rotate around the clearance section 1412 of the locking body 141. When the locking assembly 14 is in the first locked state, the second limiting rib 1411 passes through the second limiting groove 131211 and the third limiting groove 12211 to restrict the relative rotation between the telescopic rod assembly 12 and the fixed rod assembly 13. The locking assembly 14 switches between the first unlocked state and the first locked state by sliding the locking body 141.

[0064] In some embodiments, the locking assembly 14 in this embodiment further includes an elastic locking reset member 142. The elastic locking reset member 142 is sleeved on the mounting shaft 13122. The two ends of the elastic locking reset member 142 abut against the locking body 141 and the fixing rod assembly 13 respectively, and are used to apply elastic force to the locking body 141 so that the locking assembly 14 maintains the first locking state.

[0065] In some embodiments, the inner fixing rod 131 includes an upper fixing rod shell 1311 and a lower fixing rod shell 1312. The upper fixing rod shell 1311 is mounted on the lower fixing rod shell 1312 to form a fixed inner rod. In this embodiment, the receiving hole 13121 and the mounting shaft 13122 are both provided in the lower fixing rod shell 1312. The second end of the telescopic rod assembly 12 is located between the upper fixing rod shell 1311 and the lower fixing rod shell 1312. The two ends of the elastic locking reset member 142 abut against the locking body 141 and the lower fixing rod shell 1312 respectively, and are used to apply an elastic force close to the upper fixing rod shell 1311 to the locking body 141. By splitting the inner fixing rod 131 into the upper fixing rod shell 1311 and the lower fixing rod shell 1312, the assembly and maintenance of internal components can be facilitated, and the processing difficulty of the inner fixing rod 131 can be reduced.

[0066] In some embodiments, the elastic latch reset member 142 in this embodiment is a compression spring. Of course, in other embodiments, the elastic latch reset member 142 in this embodiment can also be other types of elastic devices.

[0067] In some embodiments, when the latch assembly 14 is in the first unlocked state, the telescopic rod assembly 12 can rotate around the clearance section 1412 of the latch body 141. When the telescopic rod assembly 12 rotates to a certain angle, the position of the second limiting rib 1411 will be aligned with the position of the third limiting groove 12211. At this time, the latch body 141 can slide under the elastic force applied by the elastic latch reset member 142, so that the second limiting rib 1411 is partially inserted into the third limiting groove 12211. The rib 1411 simultaneously engages with the second limiting groove 131211 and the third limiting groove 12211 to restrict the relative rotation of the telescopic rod assembly 12 and the fixed rod assembly 13. When it is necessary to switch to the unlocked state, simply press the latch body 141 in the opposite direction to separate the second limiting rib 1411 from the third limiting groove 12211. At this time, the second mounting hole 1221 corresponds to the position of the clearance section 1412 of the latch body 141, and the telescopic rod assembly 12 can rotate around the clearance section 1412 of the latch body 141.

[0068] In some embodiments, the number of second limiting ribs 1411 and third limiting grooves 12211 in this embodiment are both multiple. The multiple second limiting ribs 1411 are equally spaced along the circumference of the locking body 141, and the multiple third limiting grooves 12211 correspond one-to-one with the multiple second limiting ribs 1411. Through the cooperation of multiple circumferentially equally spaced second limiting ribs 1411 and third limiting grooves 12211, a multi-point evenly distributed anti-rotation structure can be formed, and multi-position locking of the telescopic rod assembly 12 can also be achieved, improving the versatility of the handle device.

[0069] In some embodiments, the number of second limiting ribs 1411 and third limiting grooves 12211 in this embodiment are both four. The four second limiting ribs 1411 are evenly spaced along the circumference of the locking body 141, and the four third limiting grooves 12211 correspond one-to-one with the four second limiting ribs 1411. Through the cooperation of the four circumferentially evenly distributed second limiting ribs 1411 and third limiting grooves 12211, a multi-point evenly distributed anti-rotation structure can be formed, and multi-position locking of the telescopic rod assembly 12 can also be achieved, improving the versatility of the handle device.

[0070] In some embodiments, the number of third limiting grooves 12211 in this embodiment is multiple. These multiple third limiting grooves 12211 are equally spaced along the circumference of the second mounting hole 1221, and any one of the multiple third limiting grooves 12211 can correspond to the position of the second limiting rib 1411. By selectively engaging the second limiting rib 1411 with the multiple circumferentially equally spaced third limiting grooves 12211, multi-position locking of the telescopic rod assembly 12 can be achieved, improving the versatility of the handle device.

[0071] In some specific embodiments, the telescopic rod assembly 12 in this embodiment includes a first rod 121 and a second rod 122. The extension direction of the first rod 121 is the same as the extension direction of the second rod 122. The first rod 121 is slidably mounted on the second rod 122 along the extension direction of the second rod 122. The handle body 11 is connected to the first rod 121, and the second rod 122 is connected to the device body 30. The telescopic rod assembly 12 extends and retracts through the relative sliding of the first rod 121 and the second rod 122. Through the relative sliding of the first rod 121 and the second rod 122, the telescopic rod assembly 12 can achieve stepless or stepped extension and retraction, meeting the operating height requirements of different users.

[0072] In some embodiments, the first rod 121 is slidably sleeved on the second rod 122. A guide protrusion is provided on the inner sidewall of the first rod 121, and a guide groove is provided on the outer sidewall of the second rod 122. Both the guide protrusion and the guide groove extend along the axial direction of the telescopic rod assembly 12. The guide protrusion is adapted to the guide groove, and the guide protrusion is slidably inserted into the guide groove. Through the sliding cooperation between the guide protrusion and the guide groove, the rotation of the first rod 121 relative to the second rod 122 along the axis of the first rod 121 can be effectively restricted. At the same time, the relative sliding of the first rod 121 and the second rod 122 can be effectively guided.

[0073] See Figure 2 As shown, in some specific embodiments, the telescopic rod assembly 12 in this embodiment further includes a length locking assembly 123. The length locking assembly 123 is installed on the first rod body 121, and the second rod body 122 is provided with a plurality of first snap-fit ​​structures. The plurality of first snap-fit ​​structures are spaced apart along the extension direction of the second rod body 122. The length locking assembly 123 has a second locked state and a second unlocked state. When the length locking assembly 123 is in the second locked state, the length locking assembly 123 engages with the first snap-fit ​​structures to fix the first rod body 121 and the second rod body 122 relatively. When the length locking assembly 123 is in the second unlocked state, the length locking assembly 123 separates from the first snap-fit ​​structures to allow the first rod body 121 to slide freely relative to the second rod body 122. By setting a length locking component 123 on the first rod body 121 and setting a plurality of first snap-fit ​​structures spaced apart along the extension direction on the second rod body 122, the telescopic rod assembly 12 can achieve segmented telescopic extension and retraction by cooperating with any one of the first snap-fit ​​structures through the length locking component 123, thereby meeting the operating height requirements of different users.

[0074] In some embodiments, a snap-fit ​​mounting seat is provided on the outer side wall of the first rod 121 in this embodiment. The length locking component 123 in this embodiment includes a locking snap, which is pivotally connected to the snap-fit ​​mounting seat. The pivot axis between the locking snap and the snap-fit ​​mounting seat is located between the first end and the second end of the locking snap. A second snap-fit ​​structure is provided on the first end of the locking snap. A clearance opening communicating with the inner and outer side walls is provided on the first rod 121. The position of the clearance opening corresponds to the position of the second snap-fit ​​structure. The second snap-fit ​​structure can pass through the clearance opening and engage with the first snap-fit ​​structure on the second rod 122 to fix the first rod 121 and the second rod 122 relatively. When the length locking component 123 is in the second locked state, pressing the second end of the locking snap can rotate the locking snap along its pivot axis. At this time, the locking snap... The second end moves toward the second rod 122, and the first end of the locking buckle moves away from the second rod 122. The second locking structure can separate from the first locking structure, so that the length locking assembly 123 switches from the second locked state to the second unlocked state. When the length locking assembly 123 is in the second unlocked state and the position of the second locking structure corresponds to the position of the first locking structure, lifting the second end of the locking buckle can cause the locking buckle to rotate in the opposite direction along its pivot axis. At this time, the second end of the locking buckle moves away from the second rod 122, and the first end of the locking buckle moves toward the second rod 122. The second locking structure can pass through the clearance opening and engage with the first locking structure on the second rod 122, so that the length locking assembly 123 switches from the second unlocked state to the second locked state.

[0075] In some embodiments, one of the first and second snap-fit ​​structures in this embodiment is a snap-fit ​​groove and the other is a snap-fit ​​protrusion. The snap-fit ​​groove and the snap-fit ​​protrusion are adapted to each other. Through the snap-fit ​​engagement of the snap-fit ​​protrusion and the snap-fit ​​groove, the relative sliding between the first rod 121 and the second rod 122 can be effectively restricted.

[0076] In some embodiments, the first snap-fit ​​structure is a snap-fit ​​groove, and the second snap-fit ​​structure is a snap-fit ​​protrusion. Multiple snap-fit ​​grooves are evenly spaced along the extension direction of the second rod 122. Through the cooperation of the snap-fit ​​protrusion and the snap-fit ​​groove, the telescopic rod assembly 12 can achieve equally spaced, stepped telescopic extension and retraction, meeting the operating height requirements of different users.

[0077] In some embodiments, the length locking component 123 in this embodiment further includes an elastic buckle reset member. The elastic buckle reset member in this embodiment is disposed between the buckle mounting base and the second end of the locking buckle, and is used to apply an elastic force to the second end of the locking buckle away from the first rod 121 so that the length locking component 123 can maintain the second locking state.

[0078] See Figures 1 to 3 and Figures 6 to 9 As shown, in some specific embodiments, the fixed rod assembly 13 in this embodiment is provided with a roller shaft structure. The axis of the roller shaft structure is collinear with the rotation axis between the telescopic rod assembly 12 and the fixed rod assembly 13. The roller part 20 includes a roller body 21, which is coaxially arranged and rotatably engaged with the roller shaft structure. It should be noted that the roller shaft structure in this embodiment refers to the rotational support structure provided at the end of the fixed rod assembly 13, whose axis coincides with the rotation axis of the telescopic rod assembly 12. By setting the axis of the roller shaft structure to be collinear with the rotation axis between the telescopic rod assembly 12 and the fixed rod assembly 13, the rotation axis of the roller body 21 can be kept parallel to the hinge axis of the device body 30.

[0079] In some embodiments, the axis of rotation between the telescopic rod assembly 12 and the fixed rod assembly 13 in this embodiment is perpendicular to and does not intersect with the axis of the fixed rod assembly 13. By setting the axis of rotation between the telescopic rod assembly 12 and the fixed rod assembly 13 to be perpendicular to and does not intersect with the axis of the fixed rod assembly 13, a non-concentric rotational connection can be achieved, thereby expanding the adjustable range of the handle device and enhancing the adaptability of the cleaning device connected to the handle device to different usage scenarios.

[0080] In some embodiments, the roller shaft structure in this embodiment includes a first support shaft 13111. The first support shaft 13111 is disposed on the side of the upper shell 1311 of the fixed rod near the lower shell 1312 of the fixed rod. The roller body 21 is coaxially disposed with the first support shaft 13111 and rotates in cooperation with it. Integrating the first support shaft 13111 into the assembly side of the upper shell 1311 of the fixed rod facilitates the precise positioning and stable support of the roller body 21, ensuring the smooth rotation of the roller body 21 while simplifying the assembly process of the roller body 21.

[0081] In some embodiments, the first support shaft 13111 in this embodiment is made of stainless steel. A rotating connection hole is provided on the roller body 21, and the first support shaft 13111 passes through the rotating connection hole and is clearance-fitted with it. Through the clearance fit between the stainless steel first support shaft 13111 and the rotating connection hole of the roller body 21, reliable rotational support with low friction and high wear resistance can be achieved, ensuring the smooth operation of the roller body 21.

[0082] In other embodiments, the roller shaft structure in this embodiment includes a second support shaft, which is disposed on the side of the lower housing 1312 of the fixed rod near the upper housing 1311 of the fixed rod. The roller body 21 is coaxially arranged with the second support shaft and rotates in cooperation with it. Integrating the second support shaft into the assembly side of the lower housing 1312 of the fixed rod facilitates the precise positioning and stable support of the roller body 21, ensuring the smooth rotation of the roller body 21 while simplifying the assembly process of the roller body 21.

[0083] In some embodiments, the second support shaft in this embodiment is made of stainless steel. The roller body 21 is provided with a rotating connection hole, and the second support shaft passes through the rotating connection hole and is clearance-fitted with the rotating connection hole. By using the clearance fit between the stainless steel second support shaft and the rotating connection hole of the roller body 21, a reliable rotating support with low friction and high wear resistance can be achieved, ensuring the smooth operation of the roller body 21.

[0084] In some embodiments, the roller shaft structure in this embodiment includes a third support shaft, which is disposed on the side of the lower housing 1312 away from the upper housing 1311 of the fixed rod. The roller body 21 is coaxially disposed with the third support shaft and rotates in cooperation with it. By disposing the third support shaft on the side of the lower housing 1312 away from the upper housing 1311 of the fixed rod, modular installation and precise positioning of the roller body 21 can be facilitated, simplifying the maintenance and replacement process of the roller body 21.

[0085] In some embodiments, the third support shaft in this embodiment is made of stainless steel. A rotating connection hole is provided on the roller body 21, and the third support shaft passes through the rotating connection hole and is clearance-fitted with it. Through the clearance fit between the stainless steel third support shaft and the rotating connection hole of the roller body 21, reliable rotational support with low friction and high wear resistance can be achieved, ensuring the smooth operation of the roller body 21.

[0086] In some embodiments, the roller shaft structure in this embodiment includes a fourth support shaft. The fourth support shaft is disposed on the side of the upper housing 1311 away from the lower housing 1312 of the fixed rod. The roller body 21 is coaxially disposed with the fourth support shaft and rotates in cooperation with it. By disposing the fourth support shaft on the side of the upper housing 1311 away from the lower housing 1312 of the fixed rod, modular installation and precise positioning of the roller body 21 can be facilitated, simplifying the maintenance and replacement process of the roller body 21.

[0087] In some embodiments, the fourth support shaft in this embodiment is made of stainless steel. The roller body 21 has a rotating connection hole, through which the fourth support shaft passes and is clearance-fitted. The clearance fit between the stainless steel fourth support shaft and the rotating connection hole of the roller body 21 achieves reliable rotational support with low friction and high wear resistance, ensuring the smooth operation of the roller body 21.

[0088] It is understood that the roller shaft structure in this embodiment includes at least one of the first support shaft 13111, the second support shaft, the third support shaft and the fourth support shaft, and at least one roller body 21 is correspondingly provided on each support shaft.

[0089] See Figure 1 and Figures 6 to 9As shown, according to another aspect of this application, a handle device is provided. The handle device is connected to the device body 30 of a cleaning device. The cleaning device includes a device body 30 and a cleaning seat 40, which are hinged together. The cleaning seat 40 is movable on the surface to be cleaned. The handle device includes a handle portion 10 and a roller portion 20. The handle portion 10 is rotatably mounted on the end of the device body 30 away from the cleaning seat 40. The roller portion 20 is rotatably mounted on the handle portion 10. The rotation axis of the roller portion 20 is parallel to the hinge axis between the device body 30 and the cleaning seat 40, and collinear with the rotation axis between the handle portion 10 and the device body 30. The device body 30 has a first working position and a second working position. When the main body 30 is in the first working position, the main body 30 is upright relative to the cleaning seat 40. When the main body 30 is in the second working position, the main body 30 is flat relative to the cleaning seat 40. When the main body 30 is in the second working position, the side of the main body 30 closer to the surface to be cleaned is the first side of the main body 30, and the side away from the surface to be cleaned is the second side of the main body 30. Along the direction from the second side of the main body 30 to the first side of the main body 30, the roller part 20 extends at least partially beyond the plane of the first side of the main body 30, so that when the main body 30 switches from the first working position to the second working position, the roller part 20 contacts the surface to be cleaned before the main body 30, and forms a load-bearing rolling contact with the surface to be cleaned. The handle device provided in this embodiment rotatably mounts the roller portion 20 to the handle portion 10, and makes the rotation axis of the roller portion 20 parallel to the hinge axis between the device body 30 and the cleaning seat 40, and collinear with the rotation axis between the handle portion 10 and the device body 30. At the same time, the roller portion 20 extends at least partially beyond the plane of the first side of the device body 30 in the direction from the second side to the first side of the device body 30. This allows the roller portion 20 to contact the surface to be cleaned before the device body 30 when the device body 30 is switched to the second flat working position, and to form a load-bearing rolling contact with the surface to be cleaned. This reduces the possibility of the first side of the device body 30 contacting the surface to be cleaned. Furthermore, the setting of the roller portion 20 can also transform traditional sliding friction into rolling friction, which helps to extend the service life of the handle device. At the same time, it significantly reduces the operating resistance of the handle device, making the push of the handle device more effortless and smooth, and effectively improving the user experience.

[0090] It should be noted that, in this embodiment, the handle device refers to the mechanical component connected to the main body 30 of the cleaning device and operated by the user; the cleaning seat 40 refers to the moving part that directly contacts the surface to be cleaned and performs the cleaning function; the roller part 20 refers to the circular rolling member that can rotate around a fixed axis, and its rotation axis specifically refers to the central axis of the roller's rotational movement; the load-bearing rolling contact refers to the rolling friction fit relationship formed between the roller part 20 and the surface to be cleaned when bearing the vertical load transmitted by the handle part 10.

[0091] It is understood that the first working position in this embodiment refers to the working position in which the device body 30 is in an upright state relative to the cleaning seat 40, and the second working position refers to the working position in which the device body 30 is in a horizontal state relative to the cleaning seat 40. Furthermore, in other embodiments, the device body 30 and the cleaning seat 40 in this embodiment may also be connected by equivalent movable connection structures that allow relative swinging, other than hinges. When a non-fixed axis connection is used, the rotational motion of the device body 30 relative to the cleaning seat 40 during swinging can be equivalent to rotation about a virtual hinge axis, which is determined by the instantaneous motion trajectory during the swinging process.

[0092] In some specific embodiments, the handle portion 10 in this embodiment includes a handle body 11 and a telescopic rod assembly 12. The handle body 11 is connected to a first end of the telescopic rod assembly 12, and the second end of the telescopic rod assembly 12 is rotatably connected to the device body 30. The extension and retraction of the telescopic rod assembly 12 is used to change the relative distance between the handle body 11 and the device body 30 in the axial direction of the telescopic rod assembly 12. It should be noted that, in this embodiment, the handle body 11 refers to the gripping part of the handle device that directly contacts the user's palm; the telescopic rod assembly 12 refers to an adjustable-length connecting rod, and its axial direction specifically refers to the length extension direction of the telescopic rod assembly 12; the relative distance between the handle body 11 and the device body 30 in the axial direction of the telescopic rod assembly 12 refers to the adjustable distance between the handle body 11 and the device body 30 along the axial direction of the telescopic rod assembly 12.

[0093] In some embodiments, the telescopic rod assembly 12 in this embodiment has an axial telescopic adjustment range of 0–200 mm. Of course, in other embodiments, the axial telescopic adjustment range of the telescopic rod assembly 12 in this embodiment can also be other sizes.

[0094] It is understood that the handle device in this embodiment allows users to flexibly adjust the length of the handle device according to their height and usage habits through the axial telescopic movement of the telescopic rod assembly 12, thereby obtaining the best operating posture and solving the technical problem that traditional fixed-length handles cannot be adapted to different user groups.

[0095] In some embodiments, the telescopic rod assembly 12 in this embodiment is a hollow component. By setting the telescopic rod assembly 12 as a hollow component, the handle device can be wired inside the telescopic rod assembly 12, which helps to improve the structural compactness of the handle device.

[0096] See Figures 1 to 3 As shown, in some specific embodiments, the device body 30 in this embodiment is provided with a fixed rod assembly 13, and the second end of the telescopic rod assembly 12 is rotatably mounted on the end of the fixed rod assembly 13 away from the device body; wherein, the rotation axis between the telescopic rod assembly 12 and the fixed rod assembly 13 is perpendicular to the axis of the fixed rod assembly 13 and parallel to the hinge axis of the device body 30. It should be noted that, in this embodiment, the fixed rod assembly 13 refers to a rigid support structure fixedly connected to the device body 30; the rotation axis between the telescopic rod assembly 12 and the fixed rod assembly 13 specifically refers to the central axis of the rotational movement of the telescopic rod assembly 12 relative to the fixed rod assembly 13.

[0097] In some embodiments, the fixing rod assembly 13 in this embodiment is a hollow component. By setting the fixing rod assembly 13 as a hollow component, the handle device can be wired inside the fixing rod assembly 13, which is beneficial to improving the structural compactness of the handle device.

[0098] It is understood that the handle device in this embodiment is rotatably connected to the telescopic rod assembly 12 via the fixed rod assembly 13, which enables the handle part 10 to be flexibly adjusted with multiple degrees of freedom. The axial extension and retraction of the telescopic rod assembly 12 can provide the handle part 10 with a length adjustment function, and the rotational movement around the fixed rod assembly 13 can optimize the working angle of the handle part 10, so that the handle part 10 can adapt to different cleaning postures. Setting the rotation axis between the telescopic rod assembly 12 and the fixed rod assembly 13 to be parallel to the hinge axis of the equipment can ensure the coordination of the movement of the handle part 10 and avoid uneven wear or jamming.

[0099] See Figures 6 to 9As shown, in some specific embodiments, the telescopic rod assembly 12 in this embodiment has a first position, a second position, and a third position relative to the fixed rod assembly 13; when the telescopic rod assembly 12 is in the first position, the axis of the telescopic rod assembly 12 is collinear with the axis of the fixed rod assembly 13; when the telescopic rod assembly 12 is in the second position, the telescopic rod assembly 12 rotates from the first position along a first direction by a first preset angle, so that the telescopic rod assembly 12 is folded and stored on the first side of the device body 30; when the telescopic rod assembly 12 is in the third position, the telescopic rod assembly 12 rotates from the first position along a second direction by a second preset angle, so that the telescopic rod assembly 12 is at least partially located on the second side of the device body 30; wherein, the direction from the first side of the device body 30 to the second side of the device body 30 is the first direction, and the second direction is opposite to the first direction. It should be noted that, in this embodiment, the first position refers to the reference position where the axes of the telescopic rod assembly 12 and the fixed rod assembly 13 are collinear; the second position is the folded storage state after the telescopic rod assembly 12 rotates from the first position around its rotation axis in the first direction by a preset angle; and the third position is the unfolded working state after rotating from the first position in the opposite second direction.

[0100] See Figure 8 As shown, in some embodiments, the first preset angle in this embodiment is 180°. By setting the first preset angle to 180°, the telescopic rod assembly 12 can be parallel to the fixed rod assembly 13 after being flipped, which helps to reduce the space occupied by the handle part 10 in the lateral direction of the cleaning device. Of course, in other embodiments, the first preset angle in this embodiment can also be other angles, such as 175° to 185°.

[0101] See Figure 9 As shown, in some embodiments, the second preset angle in this embodiment is 90°. By setting the second preset angle to 90°, the handle body 11 can be in a better operating position after the telescopic rod assembly 12 is extended, making it easier for the user to apply force to the handle body 11 while standing, reducing user fatigue. At the same time, setting the second preset angle to 90° can also form a stable right-angle support structure between the telescopic rod assembly 12 and the fixed rod assembly 13, which is beneficial for dispersing torsional stress during cleaning operations. Of course, in other embodiments, the second preset angle in this embodiment can also be other angles, such as 85° to 90°.

[0102] In some embodiments, when the device body 30 is in the first working position, the telescopic rod assembly 12 is set to the first position, and the height of the handle body 11 can be adjusted by the extension and retraction of the telescopic rod assembly 12, so that the user can hold the handle device. When the telescopic rod assembly 12 is set to the second position, the handle device can be folded and stored on the first side of the device body 30. At this time, the space occupied by the handle device and the device body 30 in the height direction of the cleaning device at least partially overlaps, so as to facilitate the storage of the cleaning device. When the device body 30 is in the second working position, the telescopic rod assembly 12 is set to the third position, so that the handle device has a higher spatial position relative to the cleaning device, so that the user can hold the handle device in a standing posture and push the cleaning device to clean.

[0103] See Figures 3 to 5 As shown, in some specific embodiments, the handle portion 10 in this embodiment further includes a locking assembly 14, which is slidably mounted on the fixed rod assembly 13. The locking assembly 14 has a first locked state and a first unlocked state. When the locking assembly 14 is in the first locked state, it locks into the telescopic rod assembly 12, so that the telescopic rod assembly 12 maintains a first position, a second position, or a third position. When the locking assembly 14 is in the first unlocked state, it separates from the telescopic rod assembly 12, so that the telescopic rod assembly 12 can rotate freely relative to the fixed rod assembly 13. By locking the locking assembly 14 and the telescopic rod assembly 12 in the first locked state, reliable locking of the telescopic rod assembly 12 in three working positions can be ensured, preventing accidental displacement of the telescopic rod assembly 12 during the cleaning operation of the cleaning device. By setting the locking assembly 14 to be separated from the telescopic rod assembly 12 in the first unlocked state, the telescopic rod assembly 12 can rotate freely relative to the fixed rod assembly 13, thereby quickly switching between the three working positions.

[0104] In some embodiments, the fixing rod assembly 13 includes an inner fixing rod 131 and an outer fixing rod 132. The first end of the inner fixing rod 131 is connected to the second end of the telescopic assembly. The second end of the inner fixing rod 131 passes through the first end of the outer fixing rod 132 and is fixedly connected to it. The second end of the outer fixing rod 132 is fixedly connected to the device body 30. The nested connection structure of the inner fixing rod 131 and the outer fixing rod 132 improves the structural strength and bending resistance of the fixing rod assembly 13.

[0105] In some embodiments, the fixing rod assembly 13 is provided with a mounting shaft 13122. The locking assembly 14 in this embodiment includes a locking body 141, which is provided with a first mounting hole. The locking body 141 is slidably mounted on the fixing rod assembly 13 along the axial direction of the mounting shaft 13122 through the cooperation of the first mounting hole and the mounting shaft 13122. The axis of the mounting shaft 13122 is parallel to the pivot axis of the device body 30. By setting the axis of the mounting shaft 13122 of the locking body 141 to be parallel to the pivot axis of the device body 30, it can be ensured that the locking assembly 14 is subjected to uniform force during operation and jamming can be avoided.

[0106] In some embodiments, the inner wall of the first mounting hole in this embodiment is provided with a first limiting groove extending axially therefrom, and the outer wall of the mounting shaft 13122 is provided with a first limiting rib extending axially therefrom. In this embodiment, the first limiting rib is adapted to the first limiting groove, and the first limiting rib is slidably inserted into the first limiting groove. The cooperation between the first limiting rib and the first limiting groove can effectively prevent the locking body 141 from rotating around the axis of the mounting shaft 13122. Through the axial sliding cooperation between the first limiting rib and the first limiting groove, it can be ensured that the locking body 141 slides smoothly along the mounting shaft 13122 while preventing the locking body 141 from rotating around the mounting shaft 13122. This maintains the linear motion accuracy of the locking and unlocking operations and avoids positioning failure caused by accidental torsion, significantly improving the working reliability and service life of the locking assembly 14.

[0107] In some embodiments, there are multiple first limiting grooves and multiple first limiting ribs in this embodiment. Multiple first limiting ribs are arranged at intervals along the circumferential direction of the mounting shaft 13122. Multiple first limiting grooves correspond one-to-one with multiple first limiting ribs. Through the cooperation of multiple sets of first limiting grooves and first limiting ribs, multiple points of locking body 141 can be limited, further avoiding positioning failure of locking body 141 due to accidental torsion.

[0108] In some embodiments, the fixing rod assembly 13 of this embodiment is provided with a receiving hole 13121. The mounting shaft 13122 of this embodiment is disposed in the receiving hole 13121 and is coaxially disposed with the receiving hole 13121. The locking body 141 is at least partially inserted into the receiving hole 13121 through sliding cooperation with the mounting shaft 13122. A second limiting rib 1411 is provided on the outer side wall of the locking body 141, and a second limiting groove 131211 is provided on the inner side wall of the receiving hole 13121. In this embodiment, the second limiting rib 1411 is adapted to the second limiting groove 131211, and the second limiting rib 1411 is slidably inserted into the second limiting groove 131211. The cooperation between the second limiting rib 1411 and the second limiting groove 131211 can effectively prevent the locking body 141 from rotating around the axis of the receiving hole 13121. By axially sliding the second limiting rib 1411 with the second limiting groove 131211, it is possible to ensure that the locking body 141 slides smoothly along the receiving hole 13121 while preventing the locking body 141 from rotating around the receiving hole 13121. This maintains the linear motion accuracy of the locking and unlocking operations and avoids positioning failure caused by accidental torsion, significantly improving the working reliability and service life of the locking assembly 14.

[0109] In some embodiments, the second end of the telescopic rod assembly 12 in this embodiment is connected to the first end of the fixed rod assembly 13 via the locking body 141; a second mounting hole 1221 is provided on the second end of the telescopic rod assembly 12, and a third limiting groove 12211 is provided on the inner sidewall of the second mounting hole 1221. The third limiting groove 12211 is adapted to the second limiting rib 1411, and the position of the third limiting groove 12211 corresponds to the position of the second limiting rib 1411. The locking body 141 has an axial clearance section 1412 without the second limiting rib 1411. When the locking assembly 14 is in the first unlocked state... In the first locked state, the second limiting rib 1411 is separated from the third limiting groove 12211, and the second mounting hole 1221 corresponds to the clearance section 1412 of the locking body 141. At this time, the telescopic rod assembly 12 can rotate around the clearance section 1412 of the locking body 141. When the locking assembly 14 is in the first locked state, the second limiting rib 1411 passes through the second limiting groove 131211 and the third limiting groove 12211 to restrict the relative rotation between the telescopic rod assembly 12 and the fixed rod assembly 13. The locking assembly 14 switches between the first unlocked state and the first locked state by sliding the locking body 141.

[0110] In some embodiments, the locking assembly 14 in this embodiment further includes an elastic locking reset member 142. The elastic locking reset member 142 is sleeved on the mounting shaft 13122. The two ends of the elastic locking reset member 142 abut against the locking body 141 and the fixing rod assembly 13 respectively, and are used to apply elastic force to the locking body 141 so that the locking assembly 14 maintains the first locking state.

[0111] In some embodiments, the inner fixing rod 131 includes an upper fixing rod shell 1311 and a lower fixing rod shell 1312. The upper fixing rod shell 1311 is mounted on the lower fixing rod shell 1312 to form a fixed inner rod. In this embodiment, the receiving hole 13121 and the mounting shaft 13122 are both provided in the lower fixing rod shell 1312. The second end of the telescopic rod assembly 12 is located between the upper fixing rod shell 1311 and the lower fixing rod shell 1312. The two ends of the elastic locking reset member 142 abut against the locking body 141 and the lower fixing rod shell 1312 respectively, and are used to apply an elastic force close to the upper fixing rod shell 1311 to the locking body 141. By splitting the inner fixing rod 131 into the upper fixing rod shell 1311 and the lower fixing rod shell 1312, the assembly and maintenance of internal components can be facilitated, and the processing difficulty of the inner fixing rod 131 can be reduced.

[0112] In some embodiments, the elastic latch reset member 142 in this embodiment is a compression spring. Of course, in other embodiments, the elastic latch reset member 142 in this embodiment can also be other types of elastic devices.

[0113] In some embodiments, when the latch assembly 14 is in the first unlocked state, the telescopic rod assembly 12 can rotate around the clearance section 1412 of the latch body 141. When the telescopic rod assembly 12 rotates to a certain angle, the position of the second limiting rib 1411 will be aligned with the position of the third limiting groove 12211. At this time, the latch body 141 can slide under the elastic force applied by the elastic latch reset member 142, so that the second limiting rib 1411 is partially inserted into the third limiting groove 12211. The rib 1411 simultaneously engages with the second limiting groove 131211 and the third limiting groove 12211 to restrict the relative rotation of the telescopic rod assembly 12 and the fixed rod assembly 13. When it is necessary to switch to the unlocked state, simply press the latch body 141 in the opposite direction to separate the second limiting rib 1411 from the third limiting groove 12211. At this time, the second mounting hole 1221 corresponds to the position of the clearance section 1412 of the latch body 141, and the telescopic rod assembly 12 can rotate around the clearance section 1412 of the latch body 141.

[0114] In some embodiments, the number of second limiting ribs 1411 and third limiting grooves 12211 in this embodiment are both multiple. The multiple second limiting ribs 1411 are equally spaced along the circumference of the locking body 141, and the multiple third limiting grooves 12211 correspond one-to-one with the multiple second limiting ribs 1411. Through the cooperation of multiple circumferentially equally spaced second limiting ribs 1411 and third limiting grooves 12211, a multi-point evenly distributed anti-rotation structure can be formed, and multi-position locking of the telescopic rod assembly 12 can also be achieved, improving the versatility of the handle device.

[0115] In some embodiments, the number of second limiting ribs 1411 and third limiting grooves 12211 in this embodiment are both four. The four second limiting ribs 1411 are evenly spaced along the circumference of the locking body 141, and the four third limiting grooves 12211 correspond one-to-one with the four second limiting ribs 1411. Through the cooperation of the four circumferentially evenly distributed second limiting ribs 1411 and third limiting grooves 12211, a multi-point evenly distributed anti-rotation structure can be formed, and multi-position locking of the telescopic rod assembly 12 can also be achieved, improving the versatility of the handle device.

[0116] In some embodiments, the number of third limiting grooves 12211 in this embodiment is multiple. These multiple third limiting grooves 12211 are equally spaced along the circumference of the second mounting hole 1221, and any one of the multiple third limiting grooves 12211 can correspond to the position of the second limiting rib 1411. By selectively engaging the second limiting rib 1411 with the multiple circumferentially equally spaced third limiting grooves 12211, multi-position locking of the telescopic rod assembly 12 can be achieved, improving the versatility of the handle device.

[0117] In some specific embodiments, the telescopic rod assembly 12 in this embodiment includes a first rod 121 and a second rod 122. The extension direction of the first rod 121 is the same as the extension direction of the second rod 122. The first rod 121 is slidably mounted on the second rod 122 along the extension direction of the second rod 122. The handle body 11 is connected to the first rod 121, and the second rod 122 is connected to the device body 30. The telescopic rod assembly 12 extends and retracts through the relative sliding of the first rod 121 and the second rod 122. Through the relative sliding of the first rod 121 and the second rod 122, the telescopic rod assembly 12 can achieve stepless or stepped extension and retraction, meeting the operating height requirements of different users.

[0118] In some embodiments, the first rod 121 is slidably sleeved on the second rod 122. A guide protrusion is provided on the inner sidewall of the first rod 121, and a guide groove is provided on the outer sidewall of the second rod 122. Both the guide protrusion and the guide groove extend along the axial direction of the telescopic rod assembly 12. The guide protrusion is adapted to the guide groove, and the guide protrusion is slidably inserted into the guide groove. Through the sliding cooperation between the guide protrusion and the guide groove, the rotation of the first rod 121 relative to the second rod 122 along the axis of the first rod 121 can be effectively restricted. At the same time, the relative sliding of the first rod 121 and the second rod 122 can be effectively guided.

[0119] In some specific embodiments, the telescopic rod assembly 12 in this embodiment includes a first rod 121 and a second rod 122. The extension direction of the first rod 121 is the same as the extension direction of the second rod 122. The first rod 121 is slidably mounted on the second rod 122 along the extension direction of the second rod 122. The handle body 11 is connected to the first rod 121, and the second rod 122 is connected to the device body 30. The telescopic rod assembly 12 extends and retracts through the relative sliding of the first rod 121 and the second rod 122. Through the relative sliding of the first rod 121 and the second rod 122, the telescopic rod assembly 12 can achieve stepless or stepped extension and retraction, meeting the operating height requirements of different users.

[0120] In some embodiments, a snap-fit ​​mounting seat is provided on the outer side wall of the first rod 121 in this embodiment. The length locking component 123 in this embodiment includes a locking snap, which is pivotally connected to the snap-fit ​​mounting seat. The pivot axis between the locking snap and the snap-fit ​​mounting seat is located between the first end and the second end of the locking snap. A second snap-fit ​​structure is provided on the first end of the locking snap. A clearance opening communicating with the inner and outer side walls is provided on the first rod 121. The position of the clearance opening corresponds to the position of the second snap-fit ​​structure. The second snap-fit ​​structure can pass through the clearance opening and engage with the first snap-fit ​​structure on the second rod 122 to fix the first rod 121 and the second rod 122 relatively. When the length locking component 123 is in the second locked state, pressing the second end of the locking snap can rotate the locking snap along its pivot axis. At this time, the locking snap... The second end moves toward the second rod 122, and the first end of the locking buckle moves away from the second rod 122. The second locking structure can separate from the first locking structure, so that the length locking assembly 123 switches from the second locked state to the second unlocked state. When the length locking assembly 123 is in the second unlocked state and the position of the second locking structure corresponds to the position of the first locking structure, lifting the second end of the locking buckle can cause the locking buckle to rotate in the opposite direction along its pivot axis. At this time, the second end of the locking buckle moves away from the second rod 122, and the first end of the locking buckle moves toward the second rod 122. The second locking structure can pass through the clearance opening and engage with the first locking structure on the second rod 122, so that the length locking assembly 123 switches from the second unlocked state to the second locked state.

[0121] In some embodiments, one of the first and second snap-fit ​​structures in this embodiment is a snap-fit ​​groove and the other is a snap-fit ​​protrusion. The snap-fit ​​groove and the snap-fit ​​protrusion are adapted to each other. Through the snap-fit ​​engagement of the snap-fit ​​protrusion and the snap-fit ​​groove, the relative sliding between the first rod 121 and the second rod 122 can be effectively restricted.

[0122] In some embodiments, the first snap-fit ​​structure is a snap-fit ​​groove, and the second snap-fit ​​structure is a snap-fit ​​protrusion. Multiple snap-fit ​​grooves are evenly spaced along the extension direction of the second rod 122. Through the cooperation of the snap-fit ​​protrusion and the snap-fit ​​groove, the telescopic rod assembly 12 can achieve equally spaced, stepped telescopic extension and retraction, meeting the operating height requirements of different users.

[0123] In some embodiments, the length locking component 123 in this embodiment further includes an elastic buckle reset member. The elastic buckle reset member in this embodiment is disposed between the buckle mounting base and the second end of the locking buckle, and is used to apply an elastic force to the second end of the locking buckle away from the first rod 121 so that the length locking component 123 can maintain the second locking state.

[0124] See Figure 2 As shown, in some specific embodiments, the telescopic rod assembly 12 in this embodiment further includes a length locking assembly 123. The length locking assembly 123 is installed on the first rod body 121, and the second rod body 122 is provided with a plurality of first snap-fit ​​structures. The plurality of first snap-fit ​​structures are spaced apart along the extension direction of the second rod body 122. The length locking assembly 123 has a second locked state and a second unlocked state. When the length locking assembly 123 is in the second locked state, the length locking assembly 123 engages with the first snap-fit ​​structures to fix the first rod body 121 and the second rod body 122 relatively. When the length locking assembly 123 is in the second unlocked state, the length locking assembly 123 separates from the first snap-fit ​​structures to allow the first rod body 121 to slide freely relative to the second rod body 122. By setting a length locking component 123 on the first rod body 121 and setting a plurality of first snap-fit ​​structures spaced apart along the extension direction on the second rod body 122, the telescopic rod assembly 12 can achieve segmented telescopic extension and retraction by cooperating with any one of the first snap-fit ​​structures through the length locking component 123, thereby meeting the operating height requirements of different users.

[0125] See Figures 1 to 3 and Figures 6 to 9 As shown, in some specific embodiments, the fixed rod assembly 13 in this embodiment is provided with a roller shaft structure. The axis of the roller shaft structure is collinear with the rotation axis between the telescopic rod assembly 12 and the fixed rod assembly 13. The roller part 20 includes a roller body 21, which is coaxially arranged with and rotatably engaged with the roller shaft structure. It should be noted that the roller shaft structure in this embodiment refers to the rotational support structure provided at the end of the fixed rod assembly 13, whose axis coincides with the rotation axis of the telescopic rod assembly 12. Along the direction from the second side of the device body 30 to the first side of the device body 30, the roller body 21 in this embodiment at least partially extends beyond the plane of the first side of the device body 30. By setting the axis of the roller shaft structure to be collinear with the rotation axis between the telescopic rod assembly 12 and the fixed rod assembly 13, the rotation axis of the roller body 21 can be kept parallel to the hinge axis of the device body 30. At the same time, the roller body 21 is set to extend at least partially beyond the plane of the first side of the device body 30 in the direction from the second side to the first side of the device body 30. This allows the roller body 21 to contact the surface to be cleaned before the device body 30 when the device body 30 is switched to the second flat working position, and to form a load-bearing rolling contact with the surface to be cleaned, thereby reducing the possibility of the first side of the device body 30 contacting the surface to be cleaned.

[0126] In some embodiments, the axis of rotation between the telescopic rod assembly 12 and the fixed rod assembly 13 in this embodiment is perpendicular to and does not intersect with the axis of the fixed rod assembly 13. By setting the axis of rotation between the telescopic rod assembly 12 and the fixed rod assembly 13 to be perpendicular to and does not intersect with the axis of the fixed rod assembly 13, a non-concentric rotational connection can be achieved, thereby expanding the adjustable range of the handle device and enhancing the adaptability of the cleaning device connected to the handle device to different usage scenarios.

[0127] In some embodiments, the roller shaft structure in this embodiment includes a first support shaft 13111. The first support shaft 13111 is disposed on the side of the upper shell 1311 of the fixed rod near the lower shell 1312 of the fixed rod.

[0129] In other embodiments, the roller shaft structure in this embodiment includes a second support shaft, which is disposed on the side of the lower housing 1312 of the fixed rod near the upper housing 1311 of the fixed rod. The roller body 21 is coaxially arranged with the second support shaft and rotates in cooperation with it. Integrating the second support shaft into the assembly side of the lower housing 1312 of the fixed rod facilitates the precise positioning and stable support of the roller body 21, ensuring the smooth rotation of the roller body 21 while simplifying the assembly process of the roller body 21.

[0130] In some embodiments, the second support shaft in this embodiment is made of stainless steel. The roller body 21 is provided with a rotating connection hole, and the second support shaft passes through the rotating connection hole and is clearance-fitted with the rotating connection hole. By using the clearance fit between the stainless steel second support shaft and the rotating connection hole of the roller body 21, a reliable rotating support with low friction and high wear resistance can be achieved, ensuring the smooth operation of the roller body 21.

[0131] In some embodiments, the roller shaft structure in this embodiment includes a third support shaft, which is disposed on the side of the lower housing 1312 away from the upper housing 1311 of the fixed rod. The roller body 21 is coaxially disposed with the third support shaft and rotates in cooperation with it. By disposing the third support shaft on the side of the lower housing 1312 away from the upper housing 1311 of the fixed rod, modular installation and precise positioning of the roller body 21 can be facilitated, simplifying the maintenance and replacement process of the roller body 21.

[0132] In some embodiments, the third support shaft in this embodiment is made of stainless steel. A rotating connection hole is provided on the roller body 21, and the third support shaft passes through the rotating connection hole and is clearance-fitted with it. Through the clearance fit between the stainless steel third support shaft and the rotating connection hole of the roller body 21, reliable rotational support with low friction and high wear resistance can be achieved, ensuring the smooth operation of the roller body 21.

[0133] In some embodiments, the roller shaft structure in this embodiment includes a fourth support shaft. The fourth support shaft is disposed on the side of the upper housing 1311 away from the lower housing 1312 of the fixed rod. The roller body 21 is coaxially disposed with the fourth support shaft and rotates in cooperation with it. By disposing the fourth support shaft on the side of the upper housing 1311 away from the lower housing 1312 of the fixed rod, modular installation and precise positioning of the roller body 21 can be facilitated, simplifying the maintenance and replacement process of the roller body 21.

[0134] In some embodiments, the fourth support shaft in this embodiment is made of stainless steel. The roller body 21 has a rotating connection hole, through which the fourth support shaft passes and is clearance-fitted. The clearance fit between the stainless steel fourth support shaft and the rotating connection hole of the roller body 21 achieves reliable rotational support with low friction and high wear resistance, ensuring the smooth operation of the roller body 21.

[0135] It is understood that the roller shaft structure in this embodiment includes at least one of the first support shaft 13111, the second support shaft, the third support shaft and the fourth support shaft, and at least one roller body 21 is correspondingly provided on each support shaft.

[0136] See Figures 6 to 9 As shown, according to another aspect of this application, a cleaning device is provided, the cleaning device including a cleaning apparatus and a handle apparatus, the handle apparatus being connected to the cleaning apparatus, and the handle apparatus being the aforementioned handle apparatus.

[0137] In some embodiments, the cleaning device in this embodiment includes a device body 30 and a cleaning seat 40, the device body 30 and the cleaning seat 40 are pivotally connected, and the handle device is connected to the end of the device body 30 away from the cleaning seat 40.

[0138] According to another aspect of this application, a cleaning system is provided, comprising a base station and cleaning equipment, wherein the cleaning equipment is the aforementioned cleaning equipment. It should be noted that the base station in this embodiment is used to provide maintenance functions for the cleaning equipment.

[0139] In summary, implementing the handle device, cleaning equipment, and cleaning system provided in this embodiment has at least the following beneficial technical effects: The handle device provided in this embodiment, by rotatably mounting the roller part 20 to the handle part 10 and making the rotation axis of the roller part 20 parallel to the hinge axis of the device body 30, allows the handle part 10 to form a load-bearing rolling contact with the surface to be cleaned through the roller part 20 when the device body 30 is in the second working position lying flat. This transforms traditional sliding friction into rolling friction, extending the service life of the handle device. At the same time, it significantly reduces the operating resistance of the handle device, making the pushing of the handle device more effortless and smooth, effectively improving the user experience.

[0140] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
