Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, and in particular to a handle assembly and a cleaning device. 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] Chinese utility model patent CN223232638U discloses a handle for a cleaning device. The handle includes a handle body, a cylindrical body, and a panel assembly. The handle body is inverted L-shaped, with a hollow grip portion. The grip portion includes a handle, and a laterally extending blocking hook at the top of the handle. The blocking hook has a bottom wall, and a surrounding wall extends upwards from the bottom wall, forming an opening integrally with the top of the handle. The cylindrical body is attached to the end of the handle away from the blocking hook. The cylindrical body includes a straight section that mates with a rod assembly. The axis of the grip portion forms an angle of less than 90 degrees with the axis of the straight section. The panel assembly covers the opening of the handle body. When the angle between the rod assembly and the cleaning head is a flat angle, the top surface of the panel assembly is lower than the top surface of the cleaning head. This handle allows the cleaning device to easily and quickly enter confined spaces with limited height, such as under beds, cabinets, and tables, offering flexibility and effortless operation.

[0004] Chinese utility model patent 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; one end of the handle is provided with an anti-detachment blocking portion, which is bulging in shape, and the top of the anti-detachment blocking portion is further provided with an operation display panel assembly; the end of the handle away from the anti-detachment blocking portion is provided with an end plate assembly; the end plate assembly includes a straight cylindrical portion that cooperates with the floor scrubber rod assembly; the axis of the grip portion and the axis of the straight cylindrical portion form a certain angle, the angle range being 60-80 degrees. When the angle between the floor scrubber rod assembly and the floor scrubber 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 blocking portion of the handle assembly does not exceed the height of the cleaning head assembly, allowing the floor scrubber to easily and quickly enter narrow spaces with limited height, such as under beds, cabinets, and tables, greatly improving the flexibility, ease of use, and labor-saving of operation.

[0005] In existing technologies, floor scrubber handles all feature a grip and a display section, resulting in complex designs. Furthermore, the display and control components need to be additionally connected to the main control unit housed within the handle assembly, leading to cumbersome wiring, high manufacturing costs, and a lack of portability. Therefore, it is necessary to find a lighter handle solution with easier wiring. Utility Model Content

[0023] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0024] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," "outer," "far," "near," "front," and "rear," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0025] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] Example 1 See Figures 1-6 This embodiment provides a handle assembly for use in a cleaning device, including: a handle body 301, a switch 305, a main control component 30A disposed within the handle body 301, and a charging component; the handle body 301 is cylindrical and can be connected to the rod assembly 20 of the cleaning device; one end of the switch 305 protrudes from the handle body 301, and the other end of the switch 305 can be electrically connected to the main control component 30A; the charging component is electrically connected to the main control component 30A.

[0027] The handle body 301 adopts a cylindrical design, directly integrating the main control component 30A and the charging component internally, eliminating the need for a complex external display module or additional control unit. When charging is required, an external power source is connected to the charging component to transfer electrical energy, charging the component and ensuring the normal operation of the main control component 30A and the electrical components of the cleaning device. The charging component is electrically connected to the main control component 30A and built into the handle body 301, achieving physical integration of charging and main control functions, avoiding the need for an external charging interface or a separate circuit design.

[0028] One end of the power switch 305 protrudes from the handle body 301 for easy user operation. When the user presses or triggers the power switch 305, its other end is electrically connected to the main control component 30A located inside the handle body 301, converting the user's operation command into an electrical signal and transmitting it to the main control component 30A. The main control component 30A controls the basic functions of the floor scrubber, such as starting and stopping, based on the received signal, thus simplifying the signal transmission path.

[0029] In this embodiment, the handle body 301 adopts a cylindrical design, abandoning the complex shape of traditional cleaning device handles, reducing unnecessary structural components, lowering the overall weight and volume of the handle assembly 30, improving user grip comfort and operational flexibility, and reducing fatigue during prolonged use. The main control component 30A and charging component are both integrated within the handle body 301. The power switch 305 is directly electrically connected to the main control component 30A, and the charging component is also electrically connected to the main control component 30A. Unlike existing technologies, there is no need to separately connect the display and control components to the main control component 30A located within the rod assembly 20, greatly simplifying the internal wiring structure, reducing wiring complexity, lowering the risk of malfunctions due to excessive wiring, and improving product stability and reliability.

[0030] In one specific embodiment, see [reference] Figures 2-6 The handle assembly 30 also includes a top cover 304 and a side cover 302. The top cover 304 is detachably connected to the upper end of the handle body 301, and when installed, it seals and protects the internal structure of the upper part of the handle body 301. It can be removed when operation of the internal structure of the upper part of the handle body 301 is required. The side cover 302 is installed on the side of the handle body 301 via a detachable connection method (such as a snap-fit ​​connection or a screw connection). When the side cover 302 is correctly installed, it completely covers the main control component 30A and the charging component located inside the handle body 301, providing protection. When inspection, maintenance, or replacement of the main control component 30A or the charging component inside the handle body 301 is required, the side cover 302 can be removed from the side of the handle body 301 through specific operations (such as pressing the snap-fit ​​or unscrewing the screws), exposing the internal components for convenient operation. When the user holds the handle assembly, they can hold the handle body 301 and the side cover 302 at the same time. The user needs to raise their thumb and stretch forward to touch the power switch 305. The power switch 305 cannot be accidentally touched when the cleaning device is used normally. During maintenance, the side cover 302 can be easily opened to maintain the components installed in the handle body 301.

[0031] The top cover 304 and side cover 302 effectively seal and protect the main control component 30A and charging component inside the handle body 301, preventing dust, moisture, and other contaminants from entering the handle body 301. This avoids damage such as corrosion and short circuits to the electronic components of the main control component 30A and charging component, extending their service life and improving the reliability and stability of the handle assembly 30. Because the top cover 304 and side cover 302 are detachable, when the main control component 30A or charging component inside the handle body 301 malfunctions, maintenance personnel can quickly and easily remove the top cover 304 or side cover 302 to directly inspect, repair, or replace the faulty component without a complex disassembly process, greatly shortening maintenance time and improving maintenance efficiency. During daily use, handling, or storage, the handle assembly 30 is inevitably subject to collisions. The top cover 304 and side cover 302 can act as buffers and protectors, reducing the direct impact of external collisions on the main control component 30A and charging component inside the handle body 301, and reducing the risk of damage due to collisions.

[0032] In one specific embodiment, see [reference] Figures 2-6 The outer wall of the side cover 302 is provided with a limiting part 302d, and the top cover 304 is provided with a protruding outer edge on the same side as the limiting part 302d. A specific space is reserved between the limiting part 302d and the protruding outer edge, which naturally forms an area for the user to hold, i.e., a gripping part. When in use, the protruding outer edge can prevent the hand from slipping away from the handle body 301 when the user pulls back the cleaning device. When the user holds the handle body 301, the four fingers other than the thumb are exactly located between the limiting part 302d and the protruding outer edge. When the user pushes the cleaning device forward, the limiting part 302d can prevent the hand from slipping away from the handle body 301.

[0033] The limiting part 302d and the protruding outer edge define and support the user's hand from both sides. When the user holds the handle, the hand naturally rests on the grip, and the limiting part 302d and the protruding outer edge prevent the hand from slipping while dragging the cleaning device. The limiting part 302d and the protruding outer edge effectively limit the hand, ensuring that the hand remains stably within the grip regardless of the amount of force applied or the resistance encountered during cleaning. This prevents the hand from easily slipping, ensuring smooth cleaning operations and reducing accidents caused by hand slippage.

[0034] Meanwhile, the switch 305 is positioned close to the limiting part 302d. When the user places their hand in the grip, the fingers naturally and easily contact the switch 305 due to the natural extension direction and position of the fingers in a normal grip posture. The user can trigger the switch 305 with a simple finger movement, such as pressing, sending an electrical signal to the main control component 30A, thereby controlling the start or stop of the cleaning device. This effectively improves the convenience of the switch operation, allowing users to easily and quickly start or stop the cleaning device, saving operation time and improving cleaning efficiency.

[0035] In one specific embodiment, see [reference] Figures 2-6 The charging assembly includes a charging socket 30A1, a battery pack 30B, and a lower power plug 30C. A charging hole 306 is provided on the outer wall of the handle body 301 corresponding to the charging socket 30A1. The charging socket 30A1 can be connected to an external power source and is electrically connected to the battery pack 30B. The lower power plug 30C can be electrically connected to the electrical components of the cleaning device. The battery pack 30B is electrically connected to the lower power plug 30C and is used to power the electrical components of the cleaning device (such as the motor, display screen, etc.).

[0036] When the battery pack 30B needs to be charged, an external power source (such as a charger plug) is inserted into the charging socket 30A1 through the charging port 306. At this time, an electrical connection is established between the external power source and the charging socket 30A1, and current flows from the external power source into the charging socket 30A1. The current flowing into the charging socket 30A1 is then transmitted to the battery pack 30B through the internal circuit. The battery pack 30B begins to receive and store electrical energy, thus achieving charging. When the cleaning device needs to operate, the battery pack 30B transmits electrical energy through the internal circuit to the lower power plug 30C. The lower power plug 30C then delivers electrical energy to the various electrical components of the cleaning device, providing the necessary power support for their normal operation, enabling the cleaning device to perform various functions such as vacuuming, mopping, and displaying the working status.

[0037] A charging hole 306 is provided on the outer wall of the handle body 301 corresponding to the charging socket 30A1, making charging very convenient. Users do not need to perform complicated disassembly of the handle assembly 30 or find a special charging location. They can simply insert an external power source into the charging socket 30A1 through the charging hole 306 to charge the battery pack 30B, which greatly improves the efficiency and convenience of charging.

[0038] In one specific embodiment, see [reference] Figures 2-6 The lower end of the handle body 301 is provided with a snap-fit ​​assembly 307 and a docking member 303. The docking member 303 can be inserted into the rod assembly 20 of the cleaning device and connected through the snap-fit ​​assembly 307. The rod assembly 20 is provided with a slot corresponding to the snap-fit ​​assembly 307.

[0039] When connecting the handle assembly 30 to the rod assembly 20 of the cleaning device, the user aligns the connector 303 at the lower end of the handle body 301 with the corresponding interface on the rod assembly 20, and then inserts the connector 303 into the rod assembly 20. During insertion, the shape and size of the connector 303 match the interface of the rod assembly 20, ensuring smooth and precise insertion. Once the connector 303 is in place, the snap-fit ​​assembly 307 engages in the corresponding slot, thus achieving a secure connection between the handle assembly 30 and the rod assembly 20. The entire installation process is simple and quick, requiring no additional tools or complex procedures, allowing users to easily and quickly install the device, saving time and effort. The snap-fit ​​connection via the snap-fit ​​assembly 307 also facilitates quick separation of the handle assembly 30 from the rod assembly 20, making it easier to inspect and maintain each component, reducing maintenance costs and ease of use.

[0040] In one specific embodiment, see [reference] Figure 3 The connecting part 303 includes a handle connecting part and a connecting rod connecting part. The handle connecting part can engage with the lower cylindrical part of the handle body, and the connecting rod connecting part can engage with the upper end of the rod assembly. The handle connecting part and the connecting rod connecting part are integrally formed. The handle connecting part adopts a cylindrical slot structure, which forms an interference fit with the lower cylindrical part of the handle body 301, and achieves a stable engagement by utilizing the elastic deformation of the material. The connecting rod connecting part precisely engages with the upper end of the rod assembly through a concave-convex positioning structure (such as a buckle, thread, or wedge-shaped surface), ensuring dual locking in the axial and radial directions, thereby improving the stable connection effect between the handle assembly 30 and the rod assembly 20 of the cleaning device.

[0041] In one specific embodiment, see [reference] Figure 3 The latch assembly 307 is installed inside the handle docking part. The latch assembly 307 includes a latch support 307b and a latch extension 307a. The latch support 307b can be installed laterally inside the handle docking part and can support a spring perpendicular to the axis of the handle docking part. The latch extension 307a includes a latch button and a latching hook that are integrated into a hook shape. The spring supports the latch extension 307a. Under the elastic force of the spring, the latch button can extend out of the outer wall of the handle docking part and pass through the outer wall of the handle body 301 to prevent the handle docking part from sliding relative to the outer wall of the handle body 301. The latching hook can extend out of the outer wall of the connecting rod docking part to latch with the inner wall of the upper end of the rod assembly to prevent the connecting rod docking part from sliding relative to the rod assembly, thereby effectively improving the connection reliability of the entire latch assembly 307 and ensuring that the handle assembly 30 can be firmly connected to the rod assembly 20 of the cleaning device.

[0042] In one specific embodiment, see [reference] Figure 1 and Figure 3By pressing the buckle button with external force, both the buckle button and the hook can be retracted simultaneously. Then, by pulling the handle body 301 upwards, the handle assembly 30 can be separated from the rod assembly 20, and the connecting part between the rod body of the rod assembly 20 and the handle assembly 30 can be separated. No other tools are needed, and users can quickly separate the handle assembly 30 from the rod assembly 20. This is convenient and improves the user experience.

[0043] In one specific embodiment, see [reference] Figure 5 and Figure 6 The handle body 301 has a light-transmitting hole located directly below the power switch 305. A light guide column is also installed inside the handle body 301. The light-guiding side of the light guide column is in close contact with the LED on the main control component 30A, while the display side of the light guide column passes through the light-transmitting hole. When the user holds the handle body 301, they can directly judge the current working status of the cleaning device by observing the display status on the light guide column. Users can view the working status of the cleaning device in real time while using it. For example, different working states (quiet / standard / powerful) can be displayed through the light guide column. Users can switch working states at any time during the use of the cleaning device, thereby effectively improving cleaning efficiency and ease of use.

[0044] In one specific embodiment, see [reference] Figure 5 and Figure 6 The bottom of the power switch 305 is equipped with a waterproof silicone conductive pad, which can be directly pressed on the start / stop contact on the main control component 30A to prevent water from splashing into the main control component 30A from the gap between the power switch 305 and the handle body 301. This can effectively improve the waterproof performance and extend the service life of the main control component 30A.

[0045] Example 2 Based on the same inventive concept, see [reference] Figure 1 This embodiment proposes a cleaning device, including a rod assembly 20, a cleaning head 10, and a handle assembly 30 as described in Embodiment 1.
