Abstract
Description
Technical Field
[0001] This invention relates to the field of cleaning tools, and particularly to a connector, handle assembly, and rod assembly for cleaning tools. 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 "water and dust circulation" floor scrubbers, the handle has become the core medium for communication between the scrubber and the user. Today, 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 easily grasp the equipment information without bending 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, combination cleaning tools, in pursuit of reliable connection between the handle assembly and the lower lever assembly, have very small mating gaps between them, requiring specialized tools for separation. This design leaves consumers helpless when they need to manually separate the handle and lower lever assemblies during simple malfunctions. Existing floor scrubber handles feature complex designs with both grip and display sections, requiring additional connections to the main control board integrated within the lever assembly. This results in cumbersome wiring, high manufacturing costs, and a lack of portability. Furthermore, existing floor scrubbers, burdened with numerous unnecessary features, have heavy lever assemblies and handles, and their combined length deviates significantly from the user's traditional mop-using habits. Even with assistive devices in the mop head (such as electric assist wheels), the machine still feels too heavy (high resistance) when pushed or pulled. Finally, the complex structure and numerous integrated components in the handle of existing floor scrubbers make maintenance of the handle extremely inconvenient when the machine 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 makes it easier to separate the handle assembly and the lower rod assembly, so that different lengths of handle assembly or lower rod assembly can be replaced in time when needed to adapt to the needs of various cleaning scenarios. Summary of the Invention
[0006] To enrich the product types of cleaning tool handles, facilitate easy tool-free docking of handle and lower lever assemblies, optimize internal circuitry and grip feel, and simplify maintenance, this application provides a docking component, handle assembly, and lever assembly.

[0072] The beneficial effects of the above-described technical solutions provided in the embodiments of the present invention include at least the following:
[0073] The connector 303 provided in this application is installed as an independent unit within the handle assembly 30. On the one hand, it can efficiently connect the handle connector 303a of the connector 303 to the lower end of the handle rod 300 without tools. On the other hand, it can also connect the lower rod connector 303b of the connector 303 to the upper end of the lower rod assembly 20 without tools. This allows consumers to easily connect the handle assembly 30 and the lower rod assembly 20 the moment they take them out of the packaging of the cleaning tool without any tools. This greatly improves the ease of use and convenience of the modular cleaning tool. This modular installation method also greatly reduces unnecessary packaging materials and transportation costs, making it more environmentally friendly.
[0074] The handle assembly provided in this application connects the handle connector to the lower end of the handle rod, and the lower rod connector connects to the lower rod assembly. The connection is reinforced by a double-clasp and a spring. Specifically, the spring's elasticity causes the push button to protrude from its locking hole, while the hook engages and latches the lower rod assembly. Thus, the push button provides reinforced fixation between the handle connector and the handle rod, while the hook provides reinforced locking between the connector and the lower rod assembly. A single double-clasp achieves a double-reinforced connection, reducing the number of parts and assembly complexity. It also eliminates gaps and looseness that may exist in traditional structures, resulting in a more solid feel during push-pull operations. For disassembly, simply press the protruding push button inwards to compress the spring and move the double-clasp inwards, simultaneously releasing the hook from the lower rod assembly and the push button from the handle rod, thus separating the components. This allows users to quickly disassemble the handle assembly and lower rod assembly, improving maintenance and storage convenience.
[0075] The handle assembly provided in this application, with the handle mating part inserted into the lower end of the handle rod, achieves a basic snap-fit between the handle rod and the handle mating part by snapping the handle mating part with a snap-fit protrusion protruding from the snap-fit hole of the mating part. The push button of the double snap fastener achieves a reinforced fixation between the handle mating part and the handle rod. The two-stage snap-fit design takes into account both the ease of assembly and the firmness of the connection. The basic snap-fit ensures initial positioning, and the reinforced fixation effectively prevents accidental loosening during use, making the overall structure safer and more reliable.
[0076] The handle assembly provided in this application features a cylindrical handle 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, and solving the technical defects of existing handles that are heavy and have a poor user experience. This improves user grip comfort and operational flexibility, making the cleaning tool more portable and user-friendly, 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. When holding the handle assembly, the user can simultaneously grasp the handle and the grip. The outer surface of the grip has lateral pull and push stops that prevent the hand from slipping off the handle when the user pulls back or pushes out 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 in existing technologies. This significantly reduces the amount of wires used, simplifies the wiring structure, and lowers the risk of malfunctions such as poor contact, thus significantly improving the stability and reliability of the cleaning tool. Furthermore, the compact integrated design eliminates redundant structures, reducing the overall weight of the handle assembly and resulting in a more reasonable center of gravity distribution for the cleaning tool handle. This makes pushing and pulling the floor scrubber easier for users and significantly improves the operating feel.
[0077] The handle assembly provided in this application, by setting the grip hole to be staggered vertically with the panel hole, and with the highest point of the panel hole higher than the lowest point of the grip hole, makes the start / stop button closer to the push stop on the opposite side of the grip. When the user holds the grip, due to the natural extension direction and position of the fingers in a normal grip posture, the fingers can naturally and easily contact the start / stop button. The user only needs to perform a simple finger movement, such as pressing for a specific duration, to trigger the start / stop button, sending an electrical signal to the main control board, thereby realizing the start or stop control of the cleaning tool. This effectively improves the convenience of the switch operation, enabling convenient and quick start or stop operations of the cleaning tool, saving operation time and improving cleaning efficiency; at the same time, the requirement to press for a specific duration also greatly avoids the possibility of erroneous operation due to accidental touch of the start / stop button.

[0136] 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.
[0137] Based on this, the present invention provides a handle assembly, a lever assembly, and a cleaning tool.
[0138] In a first aspect, this application provides an embodiment of a docking component mounted on a handle assembly.
[0139] Reference Figure 6 , Figure 12 , Figures 20-26 As shown, the present invention provides a docking component 303, which is mounted on a handle assembly 30. The handle assembly 30 is detachably connected to a lower rod assembly 20. The handle assembly 30 includes a handle rod 300 with openings at both ends. The docking component 303 includes a handle docking portion 303a inserted into the lower end of the handle rod 300 and a lower rod docking portion 303b that can be connected to the lower rod assembly. The handle assembly also includes the docking component 303, a double-locking component 307, and a spring 3071. The lower end side wall of the handle rod 300 is provided with a push button locking hole 300d. The double-locking component 307 is movably disposed in the handle docking portion 303a. The double-locking component 307 is provided with a push button 307a and a hook 307b. The push button 307a protrudes from the push button locking hole 300d, and the hook 307b can be engaged and hooked into the lower rod assembly 20. The spring 3071 abuts against and drives the double-locking component 307 against the inner wall of the handle docking portion 303a.
[0140] Thus, the connector 303 is installed as an independent unit within the handle assembly. On the one hand, it allows for efficient tool-free connection between the handle connector 303a and the lower end of the handle rod 300. On the other hand, it allows tool-free connection between the lower rod connector 303b and the upper end of the lower rod assembly 20. This allows consumers to easily connect the handle assembly 30 and the lower rod assembly 20 without any tools the moment they take them out of the cleaning tool packaging. This greatly improves the ease of use and convenience of the modular cleaning tool. This modular installation method also significantly reduces unnecessary packaging materials and transportation costs, making it more environmentally friendly.
[0141] In one or more alternative embodiments, such as Figure 12 , Figures 20-26 As shown, the handle docking part 303a and the lower rod docking part 303b are integrally formed. The integral molding manufacturing process can further improve the structural strength of the docking part 303 itself and further improve the docking reliability of the handle assembly 30 and the lower rod assembly 20.
[0142] In one or more alternative embodiments, such as Figure 12 , Figures 20-26 As shown, the docking part 303 also includes a snap-fit support 306, which is fixed inside the handle docking part 303a; the double snap-fit part 306 is movably disposed between the snap-fit support 306 and the inner wall of the handle docking part 303a, one end of the spring 3071 is located inside the push button 307a, and the other end of the spring 3071 abuts against the snap-fit support 306.

[0145] In one or more alternative embodiments, such as Figure 12 , Figures 20-26 As shown, the snap-on support 306 is provided with support fixing holes (not shown in the attached figure) corresponding to the position of each groove bottom fixing hole. Each support fixing hole is axially aligned with the corresponding groove bottom fixing hole and is locked by screwing in screws.
[0146] In one or more alternative embodiments, such as Figure 12 , Figures 20-26 As shown, the side wall of the handle docking part 303a is provided with a docking part limiting protrusion 303a2 and a docking part limiting groove 303a11 that can be fitted with the lower end side wall of the handle rod 300.
[0147] In one or more alternative embodiments, such as Figures 1-12 As shown, the lower end side wall of the handle rod 300 is also provided with a docking part snap hole 303c, and the handle docking part is provided with a handle snap protrusion 303a5, which snaps into and protrudes from the docking part snap hole 303c.
[0148] In one or more alternative embodiments, such as Figure 12 , Figures 20-26 As shown, the handle docking part 303a is also provided with a button through hole located below the handle locking protrusion 303a5 (not shown in the attached figure); the push button 307a passes through the button through hole and the push button locking hole 303c in sequence.
[0149] With this configuration, the double-clasp fastener 307 is located within the docking part 303. The double-clasp fastener 307 is equipped with a push button 307a and a hook 307b, with the hook 307b holding the lower rod assembly 20. The buckle support 306 can be easily and conveniently fixed within the docking part 303 by utilizing the opening of the handle docking part 303a and at least one operating notch P provided on the side wall of the handle docking part 303a. The double-clasp fastener 307 is movably located between the support 306 and the handle docking part 303. Between the inner walls of 03a, one end of spring 3071 is inside the push button, and the other end of spring 3071 abuts against support member 306; the operating notch groove P and the bottom fixing hole provide great convenience for the buckle support member 306 to be locked with screws using its own support member fixing hole; the docking member limiting protrusion 303a2 and docking member limiting groove 303a11 of the handle docking part 303a greatly improve the convenience of docking the handle docking part 303a with the lower end of the handle rod 300. The push button 307a passes through the button through hole and the push button snap hole 303c in sequence, improving the convenience and reliability of docking the lower rod docking part 303b with the upper end of the lower rod assembly 20.
[0150] In one or more alternative embodiments, such as Figure 6 , Figure 12 , Figures 20-26 As shown, the docking component 303 also includes a lower connecting terminal block 30F. A lower power supply pin 30E is installed inside the lower connecting terminal block 30F. The lower connecting terminal block 30F is also electrically connected to the main control board connecting terminal block 30D. The main control board connecting terminal block 30D can be electrically connected to the main control board 30A installed inside the handle assembly 30. The lower connecting terminal block 30F can be electrically connected to the lower lever assembly 20 through the lower power supply pin 30E installed therein. After the docking component 303 is configured with the lower connecting terminal block 30F, which has a built-in lower power supply pin 30E and is electrically connected to the main control board connecting terminal block 30D, it forms the docking component assembly 310. The docking component assembly 310 can easily realize the mechanical and electrical connection between the handle assembly 30 and the lower lever assembly 20.
[0151] Secondly, this application provides an embodiment of a handle assembly.
[0152] Reference Figures 1-26As shown, the present invention provides a handle assembly 30, which includes a docking member 303 as described in the first aspect, a handle rod 300, a double-buckle member 307, and a spring 3071; the handle rod 300 is open at both ends and has a through-type cylindrical shape with a uniform cross-section, and the lower end side wall of the handle rod 300 is provided with a push-button locking hole 300d; the docking member 303 includes a handle docking part 303a and a lower rod docking part 303b, the handle docking part 303a being inserted into the handle rod 300. At the lower end, the lower rod docking part 303b can be connected to the lower rod assembly 20; the double snap fastener 307 is movably disposed in the handle docking part 303a, and is provided with a push button 307a and a hook 307b. The push button 307a protrudes from the push button snap hole 300d, and the hook 307b can be snapped into and hooked onto the lower rod assembly 20; the spring 3071 is in a compressed state and abuts against the double snap fastener 307; the double snap fastener 307 abuts against the inner wall of the handle docking part 303a under the elastic force of the spring 3071.
[0153] Specifically, the handle 300 is open at both ends and has a continuous, uniform cross-section cylindrical shape.
[0154] The handle assembly 30 provided by the present invention inserts the handle docking part 303a into the lower end of the handle rod 300, connects the lower rod docking part 303b to the lower rod assembly 20, and reinforces the connection through the cooperation of the double buckle 307 and the spring 3071. That is, under the elastic force of the spring 3071, the double buckle 307 abuts against the inner wall of the handle docking part 303a, thereby causing the button 307a to protrude out of the button locking hole 300d, and the hook 307b to lock into and hook the lower rod assembly 20. Thus, the push button 307a strengthens the connection between the handle docking part 303a and the handle rod 300, while the hook 307b strengthens the locking between the docking part 303 and the lower rod assembly 20. A single double-buckle fastener 307 achieves a double-strength connection, reducing the number of parts and assembly complexity. It also eliminates gaps and looseness that may exist in traditional structures, resulting in a more solid feel during push-pull operations. For disassembly, simply press the protruding push button 307a inwards to compress the spring 3071 and move it inwards. This simultaneously releases the hook 307b from the lower rod assembly 20 and the push button 307a from the handle rod 300, allowing the parts to separate quickly. This improves the convenience of maintenance and storage.
[0155] The handle assembly 30 provided by this invention, in the state where the handle docking part 303a is inserted into the lower end of the handle rod 300, is engaged by the handle engaging protrusion 303a5 and protrudes from the docking hole 300c of the docking part, thus achieving a basic engagement between the handle rod 300 and the handle docking part 303a. The pressing button 307a of the double fastener 307 achieves a reinforced fixation between the handle docking part 303a and the handle rod 300. The two-stage engagement design takes into account both ease of assembly and connection firmness. The basic engagement ensures initial positioning, while the reinforced fixation effectively prevents accidental loosening during use, making the overall structure safer and more reliable.
[0156] In one or more alternative embodiments, such as Figure 6 , Figure 8 , Figure 10 , Figure 12 , Figures 20-26 As shown, the lower end side wall of the handle rod 300 is also provided with a docking part snap hole 300c, and the handle docking part 303a is provided with a handle snap protrusion 303a5, which snaps into and protrudes from the docking part snap hole 300c.
[0157] In one or more alternative embodiments, such as Figure 6 , Figure 8 , Figure 10 , Figure 12 , Figures 20-26 As shown, the handle assembly 30 also includes a snap-fit support 306, which is fixed inside the handle docking portion 303a; a double snap-fit member 307 is movably disposed between the snap-fit support 306 and the inner wall of the handle docking portion 303a, and one end of the spring 3071 is located inside the push button 307a, while the other end abuts against the snap-fit support 306.
[0158] In one or more alternative embodiments, such as Figure 6 , Figure 12 , Figures 20-26 As shown, the side wall of the handle docking part 303a is provided with at least one operating notch P; the inner side of the bottom of each operating notch P is provided with a bottom fixing hole (not shown in the figure).

Each support fixing hole is axially aligned with the corresponding groove bottom fixing hole and is locked by screwing in screws.
[0160] In one or more alternative embodiments, such as Figure 6 , Figure 12 , Figures 20-26As shown, the handle docking part 303a is also provided with a button through hole located below the handle locking protrusion 303a5 (not shown in the attached figure); the push button 307a passes through the button through hole and the push button locking hole 300d in sequence.
[0161] In one or more alternative embodiments, such as Figure 6 , Figure 12 , Figures 20-26 As shown, the handle engaging protrusion 303a5 is surrounded by an arc-shaped hollow part 303a4, so that the handle engaging protrusion 303a5 can undergo elastic deformation.
[0162] In one or more alternative embodiments, such as Figure 12 , Figures 20-26 As shown, the side wall of the handle docking part 303a is provided with a docking part limiting protrusion 303a2 and a docking part limiting groove 303a11 that can be fitted with the lower end side wall of the handle rod.
[0163] In one or more alternative embodiments, such as Figures 1-12 As shown, the peripheral wall of the handle 300 is provided with a panel hole 300a, and a grip hole 300b is provided opposite to the panel hole 300a and staggered upwards. The lowest point of the grip hole 300b is higher than the lowest point of the panel hole 300a.
[0164] In one or more alternative embodiments, such as Figures 1-12 As shown, the handle assembly 30 also includes a bracket 30C, a panel 302, a start / stop button 305, and a grip 301; the bracket 30C is inserted into the handle rod 300; the panel 302 is fitted into the panel hole and is provided with a start / stop button hole 302a, and the start / stop button 305 protrudes from the start / stop button hole 302a; the grip 301 is installed in the grip hole 300b, and the grip 301 is fastened to the bracket 30C; when holding the handle assembly 30, the handle rod 300 and the grip 301 can be held simultaneously, and when the user holds the grip 301 with all four fingers other than the thumb, the thumb cannot touch the start / stop button 305.
[0165] In one or more alternative embodiments, such as Figure 5 , Figure 12 As shown, the lower end of bracket 30C is locked inside the handle rod by bracket fastening screws (not shown in the attached figure).
[0166] In one or more alternative embodiments, such as Figure 5 , Figure 12 As shown, panel 302 is detachably snapped onto bracket 30C.
[0167] In one or more alternative embodiments, such as Figure 1 , Figures 4-5 , Figures 8-12As shown, the highest point of the panel hole 300a is higher than the lowest point of the grip hole 300b.
[0168] In one or more alternative embodiments, when holding the handle assembly 30, the thumb needs to be raised and extended forward to reach the start / stop button 305.
[0169] With this configuration, the handle assembly 30 provided in this embodiment of the invention adopts a straight cylindrical design of a cylindrical handle 300. The panel 302 is fitted into the panel hole 300a on the side wall of the handle 300 and snapped onto the bracket 30C. The grip 301 is fitted into the grip hole 300b on the side wall of the handle 300 opposite to the panel hole 300a and fastened to the bracket 30C. The end cap assembly 308 closes the top. The entire assembly has no complex irregular grip parts or independent display modules, abandoning the complex shape of traditional cleaning tool handles. It is easy to wipe and maintain, and reduces unnecessary structural parts through structural integration, effectively reducing the overall weight and volume of the handle, optimizing the grip feel, solving the technical defects of existing handles being heavy and having a poor user experience, improving the user's grip comfort and operational flexibility, preventing accidental touch of the start / stop button, and making the cleaning tool more in line with the needs of lightweight and humanized use. The panel holes 300a and grip holes 300b, which are staggered and arranged on the side wall of the handle 300, facilitate the installation of the panel 302 and the bracket 30C into designated positions within the handle 300. During maintenance, it also facilitates the removal of the grip 301 to access and maintain the components mounted on the bracket 30C. Alternatively, the components mounted on the bracket 30C can be accessed by removing the end cap assembly 308 and then pulling out the bracket 30C.
[0170] In one or more alternative embodiments, such as Figure 5 , Figure 12 As shown, panel 302 is detachably snapped onto bracket 30C, and the lower end of bracket 30C is locked into handle rod 300 by bracket fastening screw M.
[0171] In one or more alternative embodiments, such as Figures 1-2 , Figure 5 , Figures 9-10 , Figure 12As shown, the handle assembly 30 also includes an end cap assembly 308, which is detachably fixed to the top of the handle rod 300, sealing the top opening of the handle rod 300; a bracket 30C is inserted into the handle rod 300, and the lower end of the bracket 30C is locked into the handle rod 300 by a bracket fastening screw; a panel 302 is fitted into a panel hole 300a and is provided with a start / stop button hole 302a, and the panel 302 is detachably snapped onto the bracket 30C; a start / stop button 305 protrudes from the start / stop button hole 302a; when holding the handle assembly 30, the thumb needs to be raised and extended forward to reach the start / stop button 305. The upper end of the bracket 30C abuts against the end cap assembly 308; the start / stop button 305 cannot be accidentally activated during normal use of the cleaning tool.
[0172] The handle assembly 30 provided in this embodiment of the invention integrates and fixes the main control board 30A and the battery pack 30B directly inside the handle rod 300 via a bracket 30C. The panel 302 is also provided with a charging socket through hole 302b. The main control board 30A is provided with a main control board external connection socket and a charging socket 30A1. The start / stop button 305 is directly electrically connected to the main control board 30A. The charging socket 30A1 is also directly integrated on the main control board 30A and is aligned with the charging socket through hole 302b on the panel 302. This makes full use of the cylindrical space inside the handle rod 300 and simplifies the connection method between the panel 302 and the main control board 30A. Unlike the prior art, there is no need to connect the display and control parts to the main control board 30A located in the rod assembly via wires. This not only greatly reduces the amount of wires and connection nodes and simplifies the wiring structure, but also reduces the risk of failure such as poor contact and significantly improves the stability and reliability of the product operation.
[0173] In one or more alternative embodiments, such as Figure 5 , Figure 12 As shown, the handle assembly 30 also includes a main control board 30A, which is electrically connected to a start / stop button 305. The start / stop button 305 and the start / stop button hole 302a are kept waterproof and sealed. The main control board 30A is detachably connected to the outer wall of the bracket 30C by a main control board fastening screw M. Pressing the start / stop button 305 controls the start and stop of the cleaning tool. The main control board fastening screw M passes through the bracket 30C and is threadedly connected to the main control board 30A, thereby achieving a fixed connection between the main control board 30A and the bracket 30C, which helps to improve the positioning accuracy and vibration resistance of the main control board 30A.
[0174] In one or more alternative embodiments, such as Figure 5 , Figure 12 As shown, the handle assembly 30 also includes a battery pack 30B, which is located at the center of the bracket 30C and is electrically connected to the main control board 30A.
[0175] In one or more alternative embodiments, such as Figure 5 , Figure 12 As shown, the main control board 30A is equipped with an external connection socket (not shown in the attached diagram) and a charging socket 30A1.
[0176] In one or more alternative embodiments, such as Figures 1-2 , Figure 5 , Figure 9 , Figures 11-12 As shown, panel 302 is also provided with charging socket through hole 302b, which is aligned with charging socket 30A1.
[0177] In one or more alternative embodiments, such as Figure 5 , Figure 12 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 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.
[0178] 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 stick 300, significantly improving the stability and reliability of the product's operation.
[0179] In one or more alternative embodiments, such as Figure 5 , Figure 12 As shown, at the start / stop button hole 302a, between the main control board 30A and the handle 300, a waterproof silicone conductive gasket 3051 is used to achieve waterproofing between the panel 302 and the main control board 30A.
[0180] In one or more alternative embodiments, such as Figure 5 , Figure 12 As shown, the start / stop button 305 is electrically connected to the main control board 30A. When holding the handle assembly 30, the start / stop button 305 must be pressed vertically with a pressing travel of more than 0.6 mm and a continuous pressing time of more than 2.1 seconds to switch the start / stop state of the cleaning tool. Even if the start / stop button is accidentally pressed during normal use of the cleaning tool, it will not cause misoperation.
[0181] In one or more alternative embodiments, such as Figure 5 , Figure 12As shown, panel 302 includes a panel base (not shown in the attached drawing) and a panel boss (not shown in the attached drawing) protruding relative to the panel base; the panel base is flush with the inner wall of the handle 300, and the panel boss protrudes from the panel hole 300a and is flush with the outer surface of the handle 300. With this configuration, panel 302 is used for display and operation. The panel base is secured between the inner wall of the handle 300 and the main control board 30A, ensuring stable positioning, thereby facilitating the installation of panel 302 and the electrical connection between panel 302 and the main control board 30A.
[0182] In one or more alternative embodiments, such as Figure 5 , Figure 12 As shown, when maintaining the handle assembly 30, the end cap assembly 308 can be removed and the bracket 30C can be pulled outward to maintain the components installed inside the handle rod 300.
[0183] In one or more alternative embodiments, such as Figure 5 , Figure 12 As shown, the end cap assembly 308 includes a handle inner cover 308A, a top fixing cover 308B, and a shock absorber 309. The handle inner cover 308A abuts against and seals the top of the handle rod 300 with the top of the bracket 30C. The top fixing cover 308B is fixedly connected to the top of the handle rod 300 and is fastened to the handle inner cover 308A. The shock absorber 309 is located below the handle inner cover 308A, and its upper and lower ends abut against the handle inner cover 308A and the battery pack 30B, respectively. By elastically abutting against the top fixing cover 308A and the battery pack 30B, the shock absorber 309 can effectively buffer the impact generated by the handle assembly 30 during use or drops, protecting the battery pack 30B and its internal circuitry. At the same time, the handle end cap 308B fastens to the top of the handle rod 300 and the top fixing cover 308A, respectively, achieving screwless quick assembly at the top and further enhancing the overall structural stability and shock resistance.
[0184] In one or more alternative embodiments, such as Figure 1 , Figure 5 , Figures 8-12 As shown, the upper end of the grip 301 is provided with a pull stop 301a, and the lower end of the grip 301 is provided with a push stop 301b. When the user holds the grip 301, the four fingers other than the thumb are located precisely between the push stop and the pull stop. When the user pushes the cleaning tool forward, the push stop 301b can prevent the hand from slipping off the handle, and when the user pulls the cleaning tool back, the pull stop 301a can prevent the hand from slipping off the handle, thus improving the stability and safety of operation.
[0185] In one or more alternative embodiments, such as Figure 5 , Figure 12As shown, a waterproof silicone conductive gasket 3051 is provided between the start / stop button hole 302a and the start / stop button 305, thereby forming a reliable waterproof sealing interface around the start / stop button 305. This prevents splashed liquids or humid gases from entering the main control board 30A through the button hole during cleaning. At the same time, the conductive properties of silicone ensure the stable transmission of the button trigger signal, taking into account both waterproofness and operational sensitivity.
[0186] In one or more alternative embodiments, such as Figure 5 , Figure 12 As shown, a waterproof plug 302b1 is provided around the charging socket 30A1.
[0187] In one or more alternative embodiments, such as Figures 5-7 , Figure 12 As shown, the handle assembly 30 also includes a handle electrical connection harness 304. The main control board 30A has an external connection socket. The upper end of the handle electrical connection harness 304 connects to the external connection socket, and the lower end of the handle electrical connection harness 304 connects to the lower lever electrical connection harness 202. Figure 5 , Figure 12 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.
[0188] In one or more alternative embodiments, such as Figures 1-2 , Figure 5 , Figure 9 , Figures 11-12 As shown, the panel hole 300a is located in the middle of the cylindrical part of the handle bar 300 and is racetrack-shaped. The center line of the panel hole 300a is parallel to the axis of the handle bar 300.
[0189] In one or more alternative embodiments, such as Figures 1-2 , Figure 5 , Figure 9 , Figures 11-12 As shown, after the panel 302 is fitted into the panel hole 300a, a seal is maintained around the panel hole 300a and between the panel 302 and the handle bar 300. The exposed part of the panel 302 fitted into the panel hole 300a is flush with the outer surface of the handle bar 300.
[0190] With this configuration, during assembly, the panel 302 is first inserted into the handle 300. When it reaches the panel hole 300a, the panel body is inserted into the panel hole 300a. Then, the bracket 30C, with the battery pack 30B and main control board 30A assembled, is placed into the handle 300. The position of the main control board 30A is adjusted to be aligned with the panel 302, thus ensuring a stable electrical connection between the main control board 30A and the panel 302. This eliminates the complex wiring harness between the display and control components and the main control board 30A in traditional handles, reducing the risk of poor contact due to vibration or pulling. The start / stop button 305 is fitted into the start / stop button hole 302a on the panel body and is directly electrically connected to the main control board 30A without the need for a separate wire. At the same time, the charging socket 30A1 is located on the main control board 30A and is exposed through the charging socket through hole 302b on the panel body for easy direct charging.
[0191] With this configuration, the handle assembly 30 provided in this embodiment of the invention adopts a straight cylindrical design of a cylindrical handle rod 300, which abandons the complex shape of traditional cleaning tool handles. Through compact structural integration, unnecessary structural components are reduced, effectively reducing the overall weight and volume of the handle, making the center of gravity layout more reasonable, optimizing the grip feel, solving the technical defects of existing handles being heavy and having a poor user experience, improving the user's grip comfort and operational flexibility, and making the cleaning tool more in line with the needs of lightweight and humanized use.
[0192] In one or more alternative embodiments, such as Figures 1-2 , Figure 5 , Figures 9-10 , Figure 12 As shown, the handle assembly 30 also includes a grip 301, which is installed on the side of the handle shank 300 opposite to the panel hole 300a, below the end cap assembly 308. When the user holds the handle assembly 30, they can simultaneously hold the handle shank 300 and the grip 301. The grip 301 is installed in the grip hole 300b on the rear side of the handle shank 300 and is directly fastened to the bracket 30C. The grip 301 serves both as a gripping force point and participates in the fixation of the internal structure, reducing additional fasteners and improving integration and connection stability.
[0193] 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.
[0194] In one or more alternative embodiments, refer to Figures 1-2 , Figure 5 , Figures 9-10 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 at the rear and front sides of the handle 300, respectively. When holding the tool, the user can simultaneously grip the handle 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 both sides of the handle 300 without protruding or enlarging the handle outline, maintaining the simple shape and lightweight advantage of the handle assembly 30.
[0195] In one or more alternative embodiments, the handle assembly 30 further includes a grip fastening screw (not shown in the figures). The grip fastening screw extends into the pull stop and passes through the grip 301, ultimately inserting into the end cap assembly 308 and threadedly connecting to it, thereby locking the pull stop of the grip 301 to the end cap assembly 308, improving the stability of the grip 301's installation. Furthermore, by locking the grip 301 to the end cap assembly 308 with the grip fastening screw and fixing the grip 301 to the bracket 30C with a snap-fit connection, a highly stable double-fixing structure is formed. When the user uses the tool, the force generated by pushing and pulling the cleaning tool first acts on the grip 301. The pull stop itself provides mechanical resistance, while the grip fastening screw further locks the stop to the end cap assembly 308, preventing the pull stop 301a from elastically deforming outwards or dislodging due to force. Meanwhile, the lower latch bears part of the radial and axial loads and forms an upper and lower constraint point with the upper grip fastening screw, jointly restricting the rotation of the grip 301 around the handle 300 or its movement along the handle. Compared with solutions that rely solely on latches or screws, the double fixing eliminates the limitations of single-point connection. The latch provides quick positioning and anti-rotation capability, while the grip fastening screw provides axial locking force. The two complement each other, making the grip 301 almost wobble-free and noiseless on the handle 300, and it will not loosen even after long-term use.
[0196] In one or more alternative embodiments, refer to Figure 12 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.
[0197] This application proposes several specific implementation methods for assembling the lever assembly 2 by docking the handle assembly 30 with the lower lever assembly 20, as detailed in the following more specific embodiments.
[0198] In one or more alternative embodiments, refer to Figure 4 , Figure 6 , Figures 8-12 As shown, the handle assembly 30 also includes a docking part 303 for connecting the lower rod assembly 20. The docking part 303 includes an integrally formed handle docking part 303a and a lower rod docking part 303b. The handle docking part 303a is inserted into the lower end of the handle rod 300, and the lower rod docking part 303b is used for detachable connection with the lower rod assembly 20.
[0199] Furthermore, refer to Figure 6 , Figure 9 and Figure 12As shown, the handle mating part 303a is provided with a handle engaging protrusion 303a5, and a mating member arc-shaped hollow 303a4 is provided around the handle engaging protrusion 303a5 to allow the handle engaging protrusion 303a5 to elastically deform. The handle rod 300 is provided with a mating member engaging hole 300c, and the handle engaging protrusion 303a5 engages with and protrudes from the mating member engaging hole 300c. Because the handle locking protrusion 303a5 can elastically deform, it can deflect inward when the handle mating part 303a is inserted into the handle rod 300. After the handle mating part 303a is inserted into place, the handle locking protrusion 303a5 protrudes out of the mating part locking hole 300c, thus achieving locking and fixing. If disassembly is required, simply press the handle locking protrusion 303a5 to move it inward, and the handle mating part 303a can be pulled out. This enables tool-free quick assembly and disassembly of the mating part 303 and the handle rod 300, ensuring the connection is firm and the reliability of long-term use.
[0200] In one or more alternative embodiments, refer to Figure 6 , Figure 9 and Figure 12 As shown, the handle assembly 30 also includes a double-locking member 307, a spring 3071, and a locking support member 306. The locking support member 306 is fixed inside the handle docking portion 303a. The double-locking member 307 is movably disposed between the locking support member 306 and the inner wall of the handle docking portion 303a. The spring 3071 is located between the double-locking member 307 and the locking support member 306, and is kept in a compressed state, so that the double-locking member 307 abuts against the inner wall of the handle docking portion 303a under the elastic force of the spring 3071. The lower side wall of the handle 300 is also provided with a push button locking hole 300d located below the docking part locking hole 300c. The double-locking component 307 is provided with a push button 307a and a hook 307b. Under the elastic force of the spring 3071, the push button 307a protrudes from the push button locking hole 300d, and the hook 307b can be locked into and hooked into the hook locking groove 203b of the lower rod assembly 20. In this way, the push button 307a realizes the reinforced fixation between the handle docking part 303a and the handle 300, and the hook 307b realizes the reinforced locking between the docking part 303 and the lower rod assembly 20. Only one double-locking component 307 is used to achieve a double reinforced connection, reducing the number of parts and assembly complexity, while also eliminating the gaps and looseness that may exist in traditional structures, and making the push-pull operation feel more solid. During disassembly, simply press the protruding button 307a inward to compress the double snap fastener 307 and move it inward. This will simultaneously release the hook 307b from the lower rod assembly 20 and the button 307a from the handle rod 300, thus separating the components. This allows users to quickly disassemble the handle assembly 30 and the lower rod assembly 20, improving the convenience of maintenance and storage.
[0201] Furthermore, the outer wall of the handle docking part 303a and the inner wall of the handle rod 300 are respectively provided with interlocking concave and convex structures (such as wedge-shaped surfaces) to prevent relative rotation between the handle docking part 303a and the handle rod 300, thereby avoiding loosening or separation due to torsion during use and improving the stability and durability of the overall connection.
[0202] In one or more alternative embodiments, refer to Figure 6 and Figure 12 As shown, the side wall of the handle docking part 303a has two operating notches 303a1, and the inner side of the bottom of each operating notch 303a1 has a bottom fixing hole (not shown in the attached figure). The snap-fit support 306 has two support fixing holes (not shown in the attached figure) corresponding to the positions of the two bottom fixing holes. Each support fixing hole is axially aligned with the corresponding bottom fixing hole and is locked by inserting screws. During assembly, the snap-fit support 306 is placed inside the handle docking part 303a, so that the two support fixing holes are axially aligned with the two bottom fixing holes respectively, and then two screws are inserted for fixing, so that the snap-fit support 306 and the handle docking part 303a form a rigid connection, which can effectively withstand the continuous thrust of the spring 3071 and the vibration during use, and is not easy to loosen. The operating notch 303a1 provides a direct operating window for screw tightening, eliminating the need for additional holes or complex tooling, thus reducing assembly difficulty. When it is necessary to disassemble or assemble the snap-fit support 306, the screw can also be quickly loosened through the operating notch 303a1, improving the convenience of maintenance.

[0208] Furthermore, refer to Figure 4 , Figure 6 , Figure 7 and Figure 13 As shown, the lower rod assembly 20 includes a lower rod body 200 and two connecting sleeve assemblies 203 that are detachably inserted into both axial ends of the lower rod body 200. The upper end of the docking part 303 of the handle assembly 30 is inserted into the lower end of the handle rod 300, and the lower end is detachably inserted into the connecting sleeve assembly 203 located at the upper end of the lower rod body 200. Specifically, the handle docking part 303a of the docking part 303 is inserted into the lower end of the handle rod 300, and the lower rod docking part 303b of the docking part 303 is inserted into the connecting sleeve assembly 203 located at the upper end of the lower rod body 200.
[0209] In one or more alternative embodiments, refer to Figure 6 , Figure 7 and Figure 13 As shown, the connecting sleeve assembly 203 is provided with a lower rod engaging protrusion 203a, and a connecting sleeve arc-shaped hollow 203a4 is provided around the lower rod engaging protrusion 203a so that the lower rod engaging protrusion 203a can be elastically deformed; the two ends of the lower rod body 200 are respectively provided with connecting sleeve engaging holes 200a, and the lower rod engaging protrusion 203a engages with and protrudes from the connecting sleeve engaging hole 200a.
[0210] In one or more optional embodiments, the docking component includes a handle docking portion 303a and a lower rod docking portion 303b integrally connected; the handle docking portion is provided with a handle snap-fit protrusion 303a5, and the handle snap-fit protrusion 303a5 is surrounded by an arc-shaped hollow 303a4 to allow the handle snap-fit protrusion 303a5 to elastically deform; the handle rod 300 is provided with a docking component snap-fit hole 300c, and the handle snap-fit protrusion 303a5 snaps into and protrudes from the docking component snap-fit hole 300c; the lower rod docking portion 303b is inserted into the connecting sleeve assembly 203 located at the upper end of the lower rod body 200.
[0211] In one or more alternative embodiments, refer to Figures 6-9 , Figure 13 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.
[0212] Furthermore, the outer sidewall of the connecting sleeve assembly 203 and the inner sidewall of the lower rod body 200 are respectively provided with interlocking concave-convex structures (such as wedge-shaped surfaces) to prevent the connecting sleeve assembly 203 from rotating relative to the lower rod body 200. In this way, the axial engagement and circumferential anti-rotation dual locking of the connecting sleeve assembly 203 and the lower rod body 200 are achieved, effectively avoiding loosening or disengagement caused by torsion during use, and improving the stability and durability of the overall connection.
[0213] In an optional embodiment, refer to Figure 4 , Figures 6-8 , Figure 12 and Figure 13As shown, the side wall of the connecting sleeve assembly 203 is provided with a hook-and-loop groove 203b, and the side wall of the lower rod docking part 303b is correspondingly provided with a hook-and-loop through hole 303b3. After the hooks 307b of the double-buckle fastener 307 extend into the hook-and-loop through hole 303b3 and the hook-and-loop groove 203b in sequence, they hook upwards to the upper edge of the hook-and-loop groove 203b, realizing a reliable lock between the hook 307b and the connecting sleeve assembly 203. This can effectively resist the pulling force during use and prevent the lower rod assembly 20 from accidentally coming off. The push button 307a realizes the reinforced fixation between the handle docking part 303a and the handle rod 300, and the hook 307b realizes the reinforced locking between the docking part 303 and the lower rod assembly 20. Only one double-buckle fastener 307 is used to achieve a double reinforced connection, reducing the number of parts and assembly complexity. At the same time, it also eliminates the gaps and looseness that may exist in traditional structures, and the push-pull operation feels more solid. During disassembly, simply press the protruding button 307a inward to compress the double snap fastener 307 and move it inward. This will simultaneously release the hook 307b from the connecting sleeve assembly 203 and the snap button 307a from the handle rod 300, thus separating the components. This allows users to quickly disassemble the handle assembly 30 and the lower rod assembly 20, improving the convenience of maintenance and storage.
[0214] In this embodiment, when it is necessary to connect the handle assembly 30 and the lower rod assembly 20, the user aligns the handle rod 300 with the docking part 303 assembled with the docking piece 303 with the lower rod body 200 with the connecting sleeve assembly 203 assembled with the docking piece 303.
