Description

Technical Field

[0001] This invention relates to the field of cleaning tools, and particularly to a handle assembly, a lever assembly, and a cleaning tool. Background Technology

[0002] Early floor cleaning tools used by people included brooms, mops, and floor scrubbers, which relied primarily on manual operation. With technological advancements, the demands for floor cleaning tools gradually increased, leading to the emergence of vacuum cleaners. These electric vacuum cleaners use negative pressure to suck up debris and dust from the floor. Classified by cleaning methods and the flow path of small and large debris, this type of technology is generally categorized as air-dust circulation technology. However, due to the limitations of its working principle, vacuum cleaners cannot clean some firmly attached debris and stains. Therefore, a new type of floor scrubber, the "water-dust circulation" scrubber, appeared. This scrubber uses a motor to drive a cleaning drum to wipe the floor, and is also equipped with a water supply system and a water tank to clean the cleaning drum, thus achieving a perfect floor cleaning.

[0003] In the intelligent iteration of floor scrubber products, the handle has become the core medium for communication between the floor scrubber and the user. Nowadays, mainstream flagship products are generally equipped with a high-definition LED display on the handle, which displays the battery level, cleaning mode, degree of dirt, and the status of the clean water tank and waste water tank in real time, allowing users to understand the equipment information at a glance without having to bend over.

[0004] In terms of ergonomic design, the handle has also undergone a revolutionary transformation. Chinese patent application CN222888935U discloses a floor scrubber handle, including a handle body; the main body of the handle body is a grip portion; the grip portion includes a handle; an end plate assembly is provided at the end of the handle away from the anti-detachment barrier; the end plate assembly includes a straight cylindrical portion that cooperates with the floor scrubber's rod assembly; the axis of the grip portion and the axis of the straight cylindrical portion form a certain angle, ranging from 60 to 80 degrees. When the angle between the floor scrubber's rod assembly and the floor scrubber's cleaning head assembly is close to a flat angle, the highest point of the operation display panel assembly at the top of the anti-detachment barrier of the handle does not exceed the height of the cleaning head assembly, allowing the floor scrubber to easily and quickly enter confined spaces with limited height, such as under beds, cabinets, and tables, significantly improving the flexibility, ease of use, and labor-saving aspects of operation.

[0005] In existing technologies, floor scrubber handles typically include a grip and a display, resulting in complex designs. Furthermore, the display and control components require additional connection to a main control board integrated within the handle assembly, leading to cumbersome wiring, high manufacturing costs, and a lack of portability. On the other hand, the inclusion of numerous unnecessary features in current floor scrubbers results in heavy handles and a combined length that deviates significantly from the user's traditional mop-using habits. Even with assistive devices in the mop head (such as electric assist wheels), the scrubber still feels too heavy (high resistance) when pushed or pulled. Moreover, the complex structure and numerous integrated components in the handle of existing floor scrubbers make maintenance of the handle extremely inconvenient when the scrubber malfunctions. Therefore, it is necessary to find a handle solution that is lighter, easier to connect, and easier to disassemble and maintain; in some scenarios where it is necessary to adapt to various grip distances between the handle and the cleaning head, it is also urgent to find a rod assembly technology solution that is easier to adjust, including the handle assembly and the lower rod assembly, so that the overall length of the rod assembly can be adjusted in a timely manner to meet the needs of various cleaning scenarios. Summary of the Invention

[0006] To enrich the product types of cleaning tool handles, optimize internal circuitry and grip feel, and facilitate maintenance, this invention provides a handle assembly, a rod assembly, and a cleaning tool. It abandons the complex design of traditional cleaning tool handles, reduces unnecessary structural components, and lowers the overall weight and size of the handle. When holding the handle, the user can simultaneously grasp the handle body and the grip. The user needs to raise their thumb and extend forward to reach the start / stop button, preventing accidental activation of the start / stop button during normal use. For maintenance, the grip can be easily removed, the handle end cap opened, and the bracket pulled out to maintain the components installed within the handle assembly. The grip prevents the hand from slipping off the handle. The handle assembly can also be used with lower rod assemblies of different lengths to accommodate different cleaning heads, meeting the needs of users of different heights and ages in the home.

[0051] Thirdly, embodiments of the present invention provide a cleaning tool, including a cleaning head and the rod assembly described in the second aspect.

[0052] The beneficial effects of the above-described technical solutions provided in the embodiments of the present invention include at least the following:

[0053] The handle assembly provided in this application features a cylindrical handle body design, abandoning the complex shape of traditional cleaning tool handles, reducing unnecessary structural components, lowering the overall weight and size of the handle, optimizing the grip feel, and solving the technical defects of existing handles being heavy and having a poor user experience. This improves user grip comfort and operational flexibility, making the cleaning tool more in line with the needs of lightweight and user-friendly operation, and reducing fatigue during prolonged use. When holding the handle, the user needs to raise their thumb and extend it forward to reach the start / stop button. Accidental activation of the start / stop button is prevented during normal use of the cleaning tool. For maintenance, the handle end cap can be removed, and the bracket holding the main control board can be pulled out to maintain the components installed inside the handle body. When holding the handle assembly, the user can simultaneously grasp the handle body and the grip. A lateral pull stop is provided on the outer surface of the grip, preventing the hand from slipping off the handle when the user pulls back the cleaning tool. The handle assembly provided in this invention integrates the main control board and battery pack directly inside the handle. The start / stop button is directly electrically connected to the main control board, and the charging socket is also directly integrated into the main control board, aligning with the charging socket through-hole on the panel. This simplifies the connection between the panel and the main control board, eliminating the need for wires connecting the display and control components to the main control board within the handle assembly, as is done in existing technologies. This significantly reduces the amount of wires used, simplifies the wiring structure, reduces the risk of malfunctions such as poor contact, and significantly improves the stability and reliability of the cleaning tool's operation.

[0054] The handle assembly provided in this application adopts a double-rib structure (including a central rib and a sliding groove rib) to isolate external dust and moisture from entering the internal cavity of the handle body in the sliding area. In conjunction with the charging socket through-hole on the panel and the charging socket, a waterproof gasket between the charging socket and the handle body is used to achieve waterproofing. The panel and the handle body are also sealed in a waterproof manner, which reduces the risk of malfunctions such as poor contact caused by dust and moisture entering the handle assembly, and significantly improves the stability and reliability of the cleaning tool operation.

[0055] The lever assembly provided in this application allows for timely and convenient adjustment of its overall length without affecting the normal use of the cleaning tool. The main control board and charging assembly are integrated into the handle body, with the start / stop button directly electrically connected to the main control board, and the charging assembly also electrically connected to the main control board. Unlike existing technologies, there is no need to separately connect the display and control components to the main control board located within the lever assembly. This significantly simplifies the internal wiring structure, reduces wiring complexity, lowers the risk of malfunctions due to excessive wiring, and improves product stability and reliability.

[0056] The lever assembly provided in this application includes a handle assembly that can slide in opposite directions and a lower lever assembly. The handle assembly uses a double-rib structure to isolate external dust and moisture from entering the internal cavity of the handle body in the sliding area. Since the lower lever assembly has no openings, it can completely prevent any dust and moisture from entering the lever assembly from the lower lever body. Therefore, the risk of failure such as poor contact caused by dust and moisture entering the lever assembly is reduced, and the stability and reliability of the cleaning tool operation are significantly improved.

[0100] Existing floor scrubbers all have handles with both grip and display sections, resulting in complex designs. Furthermore, the display and control components need to be connected separately to the main control board integrated within the handle assembly, leading to cumbersome wiring, high manufacturing costs, and a lack of portability. Moreover, the numerous redundant functions in most existing floor scrubbers result in complex and heavy handle structures, leading to a poor user experience when pushing or pulling the scrubber.

[0101] Based on this, the present invention provides a handle assembly, a lever assembly, and a cleaning tool.

[0102] In a first aspect, this application provides an embodiment of a handle assembly.

[0115] In one or more alternative embodiments, such as Figures 11-12 , Figures 14-15 As shown, the charging socket through-hole 302b and the charging socket 30A1 are waterproofed by the charging socket waterproof pad 302b1 between the charging socket 30A1 and the handle body 300. Furthermore, the charging socket 30A1 can adopt the internationally accepted Type-C interface, allowing users to conveniently charge the cleaning tool with any power source in their home that has a Type-C interface.

[0116] This design simplifies the internal charging circuitry for charging the battery assembly 30B built into the handle assembly 30 using an external power adapter. The adoption of a Type-C interface greatly reduces the risk of users being unable to use the cleaning tool due to a damaged power adapter. Furthermore, while simplifying the internal charging circuitry, it also enhances the waterproofing around the charging port and between the handle body 300, significantly improving the stability and reliability of the product's operation.

[0117] In one or more alternative embodiments, refer to Figure 5 , Figure 6 , Figure 14 and Figure 15 As shown, a portion of the sidewall of the handle body 300 is provided with two layers of partitions. From the inside to the outside, the handle body 300 away from the panel hole 302a is provided with a handle middle partition 300h1 and at least one handle sliding groove partition 300h2. A dustproof space is formed between the handle middle partition 300h1 and the handle sliding groove partition 300h2. The handle assembly 30 and the lower rod assembly 20 can slide towards each other / away from each other at the handle sliding groove partition 300h2.

[0118] In one or more alternative embodiments, a sliding limiting structure is provided on the handle rod sliding groove partition 300h2 to limit the sliding of the handle assembly 30 and the lower rod assembly 20 toward / away from each other when needed.

[0119] In one or more alternative embodiments, refer to Figure 5 , Figure 6 , Figure 14 and Figure 15 As shown, a stop ring 303 is sleeved on the lower end of the handle rod body 300, and the sliding restriction structure includes the stop ring 303.

[0120] Furthermore, refer to Figure 6 , Figure 9 , Figure 11 , Figures 14-15 As shown, the handle assembly 30 also includes a stop ring 303, which is sleeved on the lower end of the handle rod body 300. The top end of the stop ring 303 can abut against the bottom end of the upper end ring 201 of the lower rod assembly 20 to form a mutual stop. This ensures that the handle rod body 300 will not detach from the lower rod body 200, effectively preventing the handle rod body 300 from coming out of the lower rod body 200 when subjected to an unexpected upward pulling force, and ensuring the safe limit of the extension and retraction adjustment of the handle assembly 30 and the lower rod assembly 20.

[0121] In one or more alternative embodiments, refer to Figure 5 , Figure 6 , Figure 14 and Figure 15 As shown, the sliding limiting structure also includes a plurality of sliding groove locking holes R evenly distributed along the axis parallel to the handle rod body 300, with the handle rod sliding groove partition 300h2.

[0122] In one or more alternative embodiments, the grip has a plurality of vertically distributed buckles on the side facing the handle body, and the buckles are engaged one-to-one with the plurality of sliding groove engagement holes at the top of the sliding groove partition of the handle; the top of the other side of the grip has a pull stop that bulges slightly outward, which can prevent the hand from slipping off the handle when the cleaning tool is pulled back.

[0123] In one or more alternative embodiments, refer to Figure 5 , Figure 6 , Figure 14 and Figure 15 As shown, the sliding limiting structure is a mating structure between the length adjusting tongue protrusion 502b of the length adjusting component 50 and the sliding groove engaging hole R on the handle rod sliding groove partition 300h2. The sliding groove engaging hole R can engage the length adjusting tongue protrusion 502b of the length adjusting component 50. By engaging the sliding groove engaging holes R at different heights, the length adjusting tongue protrusion 502b achieves the telescopic fixation of the entire rod assembly 2 (handle assembly 30 + lower rod assembly 20). Thus, the sliding groove engaging hole R has a length adjustment function. When the length adjusting tongue protrusion 502b is lifted and disengaged from the sliding groove engaging hole R, relative sliding can occur between the handle assembly 30 and the lower rod assembly 20 to adjust the length of the entire rod assembly 2, which can adapt to the need for timely adjustment of the length of the rod assembly 2 in various cleaning scenarios. Furthermore, by having the top of the stop ring 303 abut against the bottom of the upper end ring 201 of the lower rod assembly 20 to form a mutual stop, the total length of the rod assembly 2 that the handle assembly 30 and the lower rod assembly 20 can be arbitrarily adjusted within a specific size range to adapt to the needs of various cleaning scenarios.

[0124] In one or more alternative embodiments, refer to Figures 1-4 , Figure 11 , Figure 12 , Figure 14 and Figure 15 As shown, the handle assembly 30 also includes a grip 301. One side of the grip 301 has multiple vertically distributed latches 301b, and the top of the other side of the grip 301 has a protruding pull stop 301a. The latches 301b are individually engaged with the uppermost sliding groove engagement holes R of the handle rod sliding groove partition 300h2. Of course, it is necessary to ensure that the uppermost latch 301b engages with the uppermost sliding groove engagement hole R, thereby ensuring that the grip 301 is installed at the uppermost part of the handle rod body 300 for easy gripping. In this way, the sliding groove engagement holes R serve two functions: length adjustment and grip 301 fixation. There is no need to separately mold mounting holes or design complex slots for the grip 301; existing length adjustment engagement holes are directly reused, reducing the number and types of openings on the handle rod body 300, which helps maintain the rod's strength and simple appearance.

[0125] In one or more alternative embodiments, refer to Figure 5 , Figure 6 , Figure 14 and Figure 15 As shown, the outer handle rod sliding groove partition 300h2 is provided with multiple vertically distributed sliding groove engaging holes R. The sliding groove engaging holes R can engage with the length adjustment tongue protrusion hook 502b of the length adjustment component 50. The length adjustment tongue protrusion hook 502b achieves the telescopic fixation of the entire rod assembly 2 (handle assembly 30 + lower rod assembly 20) by engaging with the sliding groove engaging holes R at different heights. Compared with directly drilling holes on the side wall of the handle rod body 300, the dustproof space formed by the double-layer partition ribs can intercept foreign objects in the dustproof space, effectively preventing external dust, hair, water stains, etc. from entering the interior of the handle rod body 300. This prevents foreign objects from intruding into the area where electrical components such as the main control board 30A and battery pack 30B are located inside the handle rod body 300. It is especially suitable for dusty and humid working environments such as cleaning tools, avoiding electrical short circuits, contact corrosion, or jamming failures from the source.

[0126] In one or more alternative embodiments, refer to Figure 5 , Figure 6 , Figure 14 and Figure 15 As shown, one side of the grip 301 is provided with a plurality of vertically distributed buckles 301b, which are engaged one by one into the plurality of sliding groove engagement holes R at the top of the sliding groove partition 300h2 of the handle rod; the top of the other side of the grip 301 is provided with a pull stop 301a that bulges outward, which can prevent the hand from slipping away from the handle assembly 30 when the cleaning tool is pulled back.

[0127] In one or more alternative embodiments, refer to Figure 5 , Figures 11-12 , Figures 14-15 As shown, the handle assembly 30 also includes a grip fastening screw K1, which pulls the handle rod body 300 on the side opposite to the panel hole 302a to the stop 301a, below the handle end cap 308.

[0128] In one or more alternative embodiments, refer to Figures 1-2 , Figure 8 , Figures 10-11 , Figure 14 The panel hole 302a is located in the middle of the cylindrical part of the handle bar body 300 and is racetrack shaped.

[0129] In one or more alternative embodiments, refer to Figures 4-9 As shown, the handle assembly 30 also includes a handle electrical connection harness 304, the upper end of which is connected to the external connection socket 30A2 of the main control board 30A, and the lower end of which can be connected to the lower rod electrical connection harness.

[0130] In one or more alternative embodiments, refer to Figures 1-2 , Figure 8 , Figures 10-11 , Figure 14 As shown, the panel hole 302a is racetrack shaped, and the center line of the panel hole 302a is parallel to the axis of the handle body 300.

[0131] In one or more alternative embodiments, refer to Figures 1-2 , Figure 8 , Figures 10-11 , Figure 14 As shown, after the panel 302 is fitted into the panel hole 302a, the panel 302 and the handle bar body 300 are kept sealed around the panel hole 302a. The exposed part of the panel 302 fitted into the panel hole 302a is flush with the outer surface of the handle bar body 300.

[0132] In one or more alternative embodiments, the grip 301 is made of a flexible material with a high coefficient of friction, such as silicone or rubber, which generates significant static friction between the material and the skin, effectively resisting the forward and backward sliding forces generated during the pushing and pulling of the cleaning tool. A pull stop 301a at the top of the grip 301 protrudes from the surface of the grip 301. When the user applies force backward (i.e., in a pulling direction), the stop abuts against the palm, forming a mechanical blocking structure. Even if the hands are sweaty or the grip strength is temporarily reduced, the stop prevents the hand from slipping out of the grip area. The combination of the flexible, high-friction material and the pull stop 301a greatly reduces the risk of the handle slipping out of the hand due to sweaty, slippery hands or rapid pushing and pulling movements, making it particularly suitable for cleaning tools such as floor scrubbers that require repeated pushing and pulling, thus improving safety during use.

[0133] In one or more alternative embodiments, refer to Figure 1 , Figure 4 , Figure 5 , Figure 8 , Figure 11 and Figure 12 As shown, the lowest part of the grip 301 is at the same height as the start / stop button 305. However, the grip 301 and the start / stop button 305 are located on the rear and front sides of the handle body 300, respectively. When holding the tool, the user can simultaneously grip the handle body 300 and the grip 301, and needs to raise their thumb and extend it forward to reach the start / stop button 305. During normal use of the cleaning tool, the start / stop button 305 will not be accidentally activated. When in use, the user does not need to look down; they can naturally find the button location simply by raising and extending their thumb, improving ease of operation. The start / stop button 305 and the grip 301 utilize the space on the front and rear sides of the handle body 300 without protruding or enlarging the handle outline, maintaining the simple shape and lightweight advantage of the handle assembly 30.

[0134] In one or more alternative embodiments, refer to Figure 5 As shown, the handle assembly 30 also includes a grip fastening screw K1. The grip fastening screw K1 extends into the pull stop 301a and passes through the grip 301 before finally inserting into the handle end cap 308 and threadedly connecting to it. This locks the pull stop 301a of the grip 301 to the handle end cap 308, improving the stability of the grip 301's installation. Furthermore, by fastening the grip 301 to the handle end cap 308 with the grip fastening screw K1, and by engaging the snap-fit ​​301b with the sliding groove engagement hole R, the grip 301 is fixed to the handle body 300, forming a highly stable double-fixing structure. When the user uses the cleaning tool, the force generated by pushing and pulling it first acts on the grip 301. The pull stop 301a itself provides mechanical resistance, while the grip fastening screw K1 further locks the stop to the handle end cap 308, preventing the pull stop 301a from elastically deforming outward or coming off due to force. At the same time, the lower latch 301b bears part of the radial and axial loads and forms an upper and lower constraint point with the upper grip fastening screw K1, jointly restricting the rotation of the grip 301 around the handle body 300 or its movement along the handle. Compared with solutions that rely solely on the latch 301b or solely on the screw, the double fixing eliminates the limitations of a single-point connection. The latch 301b provides quick positioning and anti-rotation capability, while the grip fastening screw K1 provides axial locking force. The two complement each other, making the grip 301 almost wobble-free and noiseless on the handle body 300, and it will not loosen even after long-term use.

[0135] In one or more alternative embodiments, refer to Figures 4-9As shown, the handle assembly 30 also includes a handle electrical connection harness 304. The main control board 30A has an external main control board connector 30A2. The upper end of the handle electrical connection harness 304 is connected to the external main control board connector 30A2, and the lower end is connected to the lower lever electrical connection harness 202 within the lower lever assembly 20. Figures 4-9 As can be seen, the entire rod assembly 2 contains only the handle electrical connection harness 304 and the lower rod electrical connection harness 202, which are connected vertically, and there are no other wiring structures. This greatly simplifies the internal electrical topology of the rod assembly 2, which not only significantly reduces the assembly difficulty and wiring harness cost, but also avoids the potential for poor contact caused by multiple connections or branch harnesses, thus further improving the electrical reliability of the whole machine.

[0136] In one or more alternative embodiments, refer to Figure 6 , Figures 9-13 As shown, the handle assembly 30 also includes a stop ring 303. The stop ring 303 is sleeved on the lower end of the handle rod body 300. The top end of the stop ring 303 can abut against the bottom end of the upper end ring 201 of the lower rod (the upper end ring 201 of the lower rod is fixed to the inner wall of the lower rod body 200) to form a mutual stop, thereby ensuring that the handle rod body 300 will not detach from the lower rod body 200. This effectively prevents the handle rod body 300 from coming out of the lower rod body 200 when subjected to an unexpected upward pulling force, ensuring the safe limit of the telescopic adjustment of the rod assembly 2, and avoiding damage to the internal handle electrical connection harness 304 and lower rod electrical connection harness 202 due to detachment.

[0137] In one or more alternative embodiments, refer to Figure 15 As shown, a waterproof gasket 302b1 for the charging socket is provided on the back of the panel 302, which is aligned with the charging socket through hole 302b. This forms an effective seal at the charging interface, preventing external liquids or dust from entering the main control board 30A area through the charging socket through hole 302b. This improves the waterproof and dustproof capabilities of the handle assembly 30 and ensures charging safety and electrical reliability.

[0138] In one or more alternative embodiments, refer to Figure 14 As shown, a waterproof silicone conductive pad 3051 is provided between the start / stop button hole 302a on the panel 302 and the start / stop button 305, thereby forming a reliable waterproof sealing interface around the start / stop button 305, preventing liquids or humid gases splashed during cleaning from entering the main control board 30A through the button hole. At the same time, the conductive properties of silicone are used to ensure the stable transmission of the button trigger signal, taking into account both waterproofness and operational sensitivity.

[0139] Secondly, this application provides an embodiment of a rod assembly.

[0140] Based on the same inventive concept, this embodiment of the invention also provides a rod assembly 2, referring to... Figures 1-4 , Figure 8 , Figures 10-12 As shown, the lever assembly 2 includes a lower lever assembly 20 and a handle assembly 30 as described in the first aspect; the handle assembly 30 is connected to the cleaning head 1 via the lower lever assembly 20; the lower lever assembly 20 includes a lower lever body 200 and an upper lower lever ring 201, the upper lower lever ring 201 being fitted and fixed to the inner wall of the upper end of the lower lever body 200; the lower end of the handle lever body 300 extends into the lower lever body 200, and the bottom end of the upper lower lever ring 201 can abut against the top end of the stop ring 303 to form mutual stop; the handle assembly 30 and the lower lever assembly 20 can slide towards each other / backwards to adjust the overall length of the lever assembly 2.

[0141] In one or more alternative embodiments, refer to Figure 6 , Figures 9-12 As shown, the lower lever assembly 20 also includes a lower lever electrical connection harness 202, a lower lever connection plug 20B, and a connecting sleeve assembly 203 inserted into the lower end of the lower lever body 200. The lower lever connection plug 20B is fixed to the upper end of the connecting sleeve assembly 203. The upper end of the lower lever electrical connection harness 202 is connected to the handle electrical connection harness 304, and the lower end is connected to the lower lever connection plug 20B. The lower end of the connecting sleeve assembly 203 is connected to the hinge head assembly 4.

[0142] With this configuration, the lower rod assembly 2 is fixed to the inner wall of the upper end of the lower rod body 200 by the upper end ring 201 of the lower rod, so that the upper end ring 201 of the lower rod and the stop ring 303 at the end of the handle rod form a mutual stop, thereby ensuring that the handle rod body 300 will not detach from the lower rod body 200. This effectively prevents the handle rod body 300 from coming out of the lower rod body 200 when subjected to an unexpected upward pulling force, ensuring the safe limit of the telescopic adjustment of the rod assembly 2, and avoiding damage to the internal handle electrical connection harness 304 and lower rod electrical connection harness 202 due to detachment.

[0143] This application proposes several specific internal structures of the length adjustment component body 500 to achieve length adjustment of the rod assembly 2, as detailed in the following more specific embodiments.

[0144] In one or more alternative embodiments, refer to Figures 1-4 , Figure 6 , Figures 8-13As shown, the rod assembly 2 also includes a length adjustment assembly 50, which is sleeved on the upper end of the lower rod body 200. The length adjustment assembly 50 includes a length adjustment member body 500. The outer wall of the length adjustment member body 500 is provided with a length adjustment tongue receiving groove 501, a length adjustment tongue body 502, and a spring Q. The length adjustment tongue body 502 is hinged in the length adjustment tongue receiving groove 501, and a length adjustment tongue protrusion hook 502b is provided on the upper part of the length adjustment tongue body 502. One end of the spring Q is fixed in the length adjustment tongue receiving groove 501, and the other end of the spring Q abuts against the lower part of the length adjustment tongue body 502. Thus, when the spring Q is in an uncompressed state, the length adjustment tongue protrusion hook 502b... When the length adjusting tongue body 502 is compressed, it can press against the sliding groove partition 300h2 of the handle rod or extend into the sliding groove locking hole R. When the spring Q is compressed, the length adjusting tongue body 502 rotates, that is, its lower end approaches the length adjusting component body 500 and its upper end moves away from the length adjusting component body 500. The length adjusting tongue protruding hook 502b can leave the sliding groove partition 300h2 of the handle rod, thereby realizing a reliable multi-position telescopic locking between the lower rod body 200 and the handle rod body 300. Moreover, the unlocking operation only requires pressing the length adjusting tongue body 502 to quickly adjust the length. The structure is compact and the operation is labor-saving. When locked, the protruding hook and the locking hole are firmly engaged and will not disengage due to vibration or pushing and pulling force, and will not affect the normal use of the cleaning tool.

[0145] In one or more alternative embodiments, refer to Figure 4 , Figure 6 , Figure 13 As shown, the sliding limiting structure is a mating structure between the length adjusting tongue protrusion 502b of the length adjusting component 50 and the sliding groove locking hole R on the sliding groove partition 300h2 of the handle rod. The sliding groove locking hole R can engage the length adjusting tongue protrusion 502b of the length adjusting component 50. By engaging the sliding groove locking holes R at different heights, the length adjusting tongue protrusion 502b achieves the telescopic fixation of the entire rod assembly 2 (handle assembly 30 + lower rod assembly 20).

[0146] In one or more alternative embodiments, refer to Figure 4 , Figure 6 , Figure 13 As shown, the length adjustment assembly 50 also includes a flat-head rivet T, which is inserted into the center of the length adjustment tongue protrusion hook 502b. The rivet head covers the end of the length adjustment tongue protrusion hook 502b to prevent the length adjustment tongue protrusion hook 502b from directly abutting against the handle rod sliding groove partition 300h2, thereby preventing wear of the length adjustment tongue protrusion hook 502b and extending the service life of the length adjustment assembly 50.

[0147] In one or more alternative embodiments, refer to Figure 6 and Figure 13As shown, the length adjusting tongue body 502 is provided with rotating support shafts 502a on both sides, and the length adjusting tongue receiving groove 501 is also provided with rotating support holes 501a on both sides. The rotating support shafts 502a are mounted between the two rotating support holes 501a and can rotate relative to the rotating support holes 501a, thereby enabling the length adjusting tongue body 502 to be hinged in the length adjusting tongue receiving groove 501.

[0148] In one or more alternative embodiments, refer to Figure 6 and Figure 13 As shown, the length adjustment assembly 50 also includes a lower rod upper ring fastening screw K4. The lower rod upper ring fastening screw K4 passes sequentially from the center of the length adjustment tongue receiving groove 501 through the length adjustment component body 500, the rod body through hole 200b on the lower rod body 200, and the upper ring through hole 201b on the lower rod upper ring 201, thereby locking and fixing the length adjustment component body 500, the lower rod body 200, and the lower rod upper ring 201, eliminating relative shaking and circumferential rotation between the components, and ensuring that the length adjustment tongue protruding hook 502b and the sliding groove locking hole R always maintain precise alignment.

[0149] In one or more alternative embodiments, refer to Figure 12 As shown, the lower end of the lower rod body 200 is provided with a connecting sleeve assembly snap-fit ​​hole 200a, and the outer side wall of the connecting sleeve assembly 203 is provided with a snap-fit ​​protrusion 203a, which can snap into the connecting sleeve assembly snap-fit ​​hole 200a. The outer side wall of the connecting sleeve assembly 203 is also provided with a snap hook snap-fit ​​groove 203b, which can snap into the inner wall of the lower rod body 200.

[0150] In one or more alternative embodiments, refer to Figure 6 and Figure 13 As shown, the lower rod body 200 is provided with a rod body clearance notch 200c, and the upper end ring 201 of the lower rod is provided with an upper end ring clearance notch 201c. The two notches are aligned and aligned with the length adjustment tongue protrusion hook 502b, thereby ensuring that the length adjustment tongue protrusion hook 502b can pass through the lower rod body 200 and the lower rod upper end ring 201 without interference during telescopic adjustment, and smoothly contact or disengage from the handle rod sliding groove partition 300h2 and the sliding groove locking hole R. This avoids jamming or locking failure caused by structural obstruction, and improves the reliability and smoothness of operation of the length adjustment mechanism.

[0151] Thirdly, this application provides an embodiment of a cleaning tool.

[0152] Based on the same inventive concept, embodiments of the present invention also provide a cleaning tool, referring to... Figures 1-4 As shown, it includes a cleaning head 1, a hinge head assembly 4, and a rod assembly 2 as described in the second aspect.

[0153] Reference Figures 1-4 , Figure 7 As shown, the hinge head assembly 4 connects the cleaning head 1 and the rod assembly 2. Specifically, the upper end of the hinge head assembly 4 is connected to the lower rod body 200 via the connecting sleeve assembly 203, and the lower end is connected to the cleaning head 1. The hinge head assembly 4 also houses the water pump P, which is connected to the cleaning head 1 via a pipeline. The lower power connector 20B can be electrically connected to the water pump P to achieve electrical connection between the water pump P and the main control board 30A.

[0154] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. This disclosure is not limited to the precise structures described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope.
