Description

Technical Field

[0001] The utility model relates to the technical field of cleaning equipment, in particular to a handle used for a cleaning device. Background Art

[0002] Early floor cleaning tools included brooms, mops, and floor scrubbers, all of which relied primarily on manual operation. With technological advancements, demands for floor cleaning tools gradually increased. The first to emerge was the vacuum cleaner, which relied on electricity to generate negative pressure to suck up trash and dust from the floor. Based on the cleaning method and the pathways through which small and large waste particles flow, this type of technology is often categorized as air-dust circulation. However, the limitations of vacuum cleaners' operating principle prevent them from removing some firmly adhered debris and stains. Consequently, a new "water-dust circulation" cleaning device has emerged. This device uses a motor to drive a cleaning cylinder to wipe the floor. These floor cleaners are also equipped with a water supply system and a sink to clean the cylinder, achieving perfect floor cleaning.

[0003] Chinese utility model patent CN220109676U discloses a handle and a handheld floor scrubber, relating to the field of cleaning devices. A handle comprises: a first telescopic component, a second telescopic component and a locking tongue component; the first telescopic component is provided with a housing cavity extending along a first direction, the second telescopic component is at least partially disposed in the housing cavity and is movable relative to the first telescopic component along the first direction, and the side wall of the housing cavity is provided with a plurality of locking holes spaced apart along the first direction; the locking tongue component is disposed on the second telescopic component, the locking tongue component has a locking tongue body, and the locking tongue body can be extended or retracted relative to the locking hole. A handheld floor scrubber comprises the above-mentioned handle. It mainly solves the problem that the handle of the current floor scrubber cannot be adjusted in length and cannot be used for people of different heights.

[0004] Chinese utility model patent CN219940516U discloses a handle structure with a speaker, including a speaker and a handle shell. A frame is provided in the handle shell, and the frame is sealed with double-sided adhesive EVA to form front and rear sound chambers. Tuning cotton is attached to the double-sided adhesive EVA, and a sound hole is opened in the handle shell in alignment with the tuning cotton. The speaker is attached and fixed to the other side of the double-sided adhesive EVA and faces the tuning cotton. By integrating the speaker into the handle, the utility model can avoid interference when the fan is working, and is closer to the human ear, the sound is relatively louder, and the three-dimensional sense when it reaches the human ear is stronger, so that the user has a better experience of the sound. In addition, by providing a circle of frame in the handle shell, sealing the front and rear sound chambers with double-sided adhesive EVA, and attaching the tuning cotton to the double-sided adhesive EVA, and opening the sound hole in the handle shell, the sound can be made rounder and richer, the vibration isolation and acoustic effects are better, and the assembly is more convenient.

[0005] Chinese utility model patent CN219940515U discloses a water volume increase handle control structure for a floor scrubber, comprising a handle housing, a PCB board connected to a main unit disposed within the handle housing; a tactile switch for controlling water volume increase disposed on the PCB board; a button disposed within the handle housing, the button being spring-loaded within the handle housing; and a push rod extending toward the tactile switch. When the button is pressed, the push rod contacts the tactile switch to activate the water volume increase function. This utility model incorporates a water volume increase switch as a button on the inside of the handle. While the user is holding the handle normally for floor scrubbing, simply pressing the button with their index finger to increase the water volume increases the water volume. This simplifies the structure, improves the design, and improves ergonomics, making operation more convenient and labor-saving.

[0006] Chinese utility model patent CN219538182U discloses a handle module and a floor scrubber. The handle module is mounted on a chassis of a cleaning device having a front roller brush and a rear roller brush. The handle module includes a fixing member, a main handle, and a locking switch. The main handle is connected to the fixing member and is configured to rotate relative to the fixing member between a first position and a second position for adjusting the pitch angle of the main handle and / or switching the cleaning device between a first working mode and a second working mode. The locking switch is provided on the fixing member or the main handle to lock the main handle to the fixing member. The handle is designed to be a split main handle and a fixing member, and the main handle is rotatably connected to the fixing member. The main handle has a variable pitch angle. When the main handle is at different pitch angles, the cleaning device can be in the same working mode or in different working modes. The user can adjust the pitch angle of the handle or switch the working mode of the cleaning device according to the actual scenario, their own height, or usage habits, so as to achieve a good user experience.

[0007] The handle of the existing "water-dust circulation" floor scrubber is inevitably occupied by a large space, no matter it is set at the end of the rod body of the floor scrubber or in a ring shape at the end of the body. Moreover, the force direction and the gripping direction of the existing handle when the user pushes or pulls the entire floor scrubber forward or backward after the user grasps it are not in a straight line. Simply put, the force direction and gripping method of the user pushing and pulling the cleaning device after grasping the handle are not ergonomic, and the user's force method is not the lightest.

[0008] At the same time, it is difficult for these existing handles to form an operating angle close to a right angle with the main body of the floor scrubber so as to enable the main body of the floor scrubber to enter a narrow space with restricted height; that is, it is difficult to achieve the so-called "lying flat" operation, so that the floor scrubber can easily and quickly enter a narrow space with restricted height such as under a bed, under a cabinet, or under a table. There is room for significant improvement in the flexibility, simplicity, and effort-saving of the operation. Utility Model Content

[0061] The present invention will be further described below with reference to specific embodiments, but this is not intended to limit the present invention.

[0062] like Figure 1-9As shown, the present invention discloses a handle, wherein the handle 10 is in the shape of an inverted L-shaped hook, is used for a cleaning device and is sleeved on the top of a rod assembly of the cleaning device. The cleaning device includes a cleaning head 30 and a rod assembly 20 pivotally connected to one end of the cleaning head. The handle 10 is sleeved on the top of the rod assembly 20 of the cleaning device. The handle 10 includes a handle body 100; the main body of the handle body 100 is a hollow gripping portion 102; the gripping portion 102 includes a gripping handle 102a The gripping handle 102a is cylindrical with a uniform cross-section. A blocking hook 102b extending laterally is provided at the top of the gripping handle 102a. The blocking hook 102b has a bottom wall (not shown in the drawings). The bottom wall has a surrounding wall extending upward (not shown in the drawings). The surrounding wall is integrally connected to the top of the gripping handle 102b to form a runway-shaped opening (not shown in the drawings). The handle 10 includes a panel assembly 110, which covers the runway-shaped opening of the handle body 100. The handle 10 also includes a straight cylindrical body 120, and the end of the gripping handle 102a away from the blocking hook 102b is connected to the straight cylindrical body 120, and the straight cylindrical body 120 includes a straight cylindrical portion 101 that cooperates with the rod assembly 20; the axis of the gripping portion 102 and the axis of the straight cylindrical portion 101 form an angle less than 90 degrees, preferably, the angle is 60-80 degrees; the relative pivoting of the rod assembly 20 and the cleaning head 30 can make the rod assembly 20 and the cleaning head 30 pivot. The angle between the rod body assembly 20 and the cleaning head 30 is continuously adjusted; when the angle between the rod body assembly 20 and the cleaning head 30 is close to a right angle, the handle 10 and the cleaning head 30 are located on the same side of the rod body assembly 20; and when the angle between the rod body assembly 20 and the cleaning head 30 is close to a straight angle, the height of the highest point of the top of the blocking hook 102b of the handle 10 above the ground does not exceed the height of the cleaning head 30 above the ground; the user (i.e., the operator) holds the handle 10 to control the cleaning head 30 to perform cleaning tasks on the ground.

[0063] The handle of the present invention has an ergonomically designed structure that is easy to hold and operate. The handle of the present invention has an inverted L-shape, which, when combined with the rod assembly, allows the user to smoothly pivot the rod assembly and the cleaning head at any angle. This allows the user to flexibly push and pull the cleaning head of the cleaning device to achieve smooth turns and change mopping routes while mopping. Furthermore, the inverted L-shape makes it difficult for the user to drop the handle, and when combined with the cleaning head, smooth turns and changes in mopping routes are achieved, allowing the user to better control the steering of the cleaning head while using the cleaning device. The handle of the utility model cooperates with the rod body assembly to realize continuous and smooth relative pivoting of the rod body assembly and the cleaning head at any angle. When the angle between the rod body assembly and the cleaning head is close to a right angle, the handle and the cleaning head are located on the same side of the rod body assembly, which can further reduce the space volume required for storing the cleaning device, and further reduce the packaging volume required for the cleaning device when it is disassembled into loose parts and packaged, thereby reducing the gross weight of the entire machine that users have to carry by hand when purchasing the cleaning device. At the same time, it also makes the cleaning device appear more slender visually, which is more conducive to users with less strength to use the cleaning device for cleaning the home environment. The handle of the present invention cooperates with the slender rod assembly, so that the cleaning device can easily and quickly enter a narrow space with restricted height, such as under a sofa, under a bed, under a cabinet, under a table, etc. Moreover, when the angle between the rod assembly and the cleaning head is close to a straight angle, the height from the ground of the highest point of the top end of the blocking hook of the handle does not exceed the height from the ground of the highest point of the cleaning head. As long as the cleaning head can pass through, the handle can also pass through easily, which greatly improves the flexibility, simplicity, labor saving and passability of the cleaning device in operating narrow spaces with restricted height.

[0064] Specifically, Figure 1 This is a three-dimensional schematic diagram of the handle 10 provided by the present invention installed on the rod assembly 20 of the cleaning device and thus connected to the cleaning head, showing the installation position of the handle in the rod assembly of the cleaning device and the overall external structure of the cleaning device composed of the handle, the rod assembly and the cleaning head of the cleaning device.

[0065] Further, such as Figure 1As shown, the cleaning device can also be called a cleaning machine or a mopping machine, which includes a cleaning head 30, that is, a cleaning head of the cleaning device, and one end of the rod assembly 20 is pivotally connected to one end of the cleaning head 30. Through the relative pivoting of the rod assembly 20 and the cleaning head 30, the angle between the rod assembly 20 and the cleaning head 30 on the normal section perpendicular to the surface to be cleaned can be continuously adjusted within a range of 0 degrees to 195 degrees. The rod assembly 20 includes a rod body 200 and a pivot member 200a that allows the rod assembly 20 and the cleaning head 30 to achieve relative pivoting. The rod assembly 20 is configured to be extremely slender. When the rod assembly 20 is pivoted about the hinged end of the pivot member 200a to a state where it is completely in contact with the top upper surface of the cleaning head 30, at this time, the angle between the rod assembly 20 and the cleaning head 30 on the normal section perpendicular to the surface to be cleaned is 0 degrees. When the cleaning device is cleaning a narrow space such as under a sofa or under a bed, and the distance between the cleaning area and the edge of the sofa or bed does not exceed the length of the cleaning device rod assembly 20, the rod assembly 20 pivots around the hinged end to open to a position completely parallel to the top upper surface of the cleaning head 30. At this time, the angle between the rod assembly 20 and the cleaning head 30 on the normal section perpendicular to the surface to be cleaned is 180 degrees. When the cleaning device is cleaning a narrow space such as under a sofa or under a bed, and the distance between the cleaning area and the edge of the sofa or bed exceeds the length of the cleaning device rod assembly 20, the user needs to hold the handle and use the length of his arm to clean the deeper area under the sofa or under the bed. Because the hinged end of the rod assembly 20 and the cleaning head 30 at the pivot member 200a is at a height close to the upper surface of the cleaning head, and the entire handle 10 has been pushed into the height limit area of the narrow space, the lowest point of this end of the handle 10 is lower than the height of the upper surface of the cleaning head. At this time, the handle 10 sleeved on the rod assembly 20 is as follows Figure 2 、 Figure 3 In the posture shown, the angle between the rod assembly 20 and the cleaning head 30 on the normal section perpendicular to the surface to be cleaned is 195 degrees.

[0066] Furthermore, in order to make the body of the cleaning device more textured, more substantial and have sufficient strength, the rod assembly 20 can be made slightly thicker. At this time, if the angle between the rod assembly 20 and the cleaning head 30 on the normal section perpendicular to the surface to be cleaned is still desired to be 0 degrees, it is necessary to raise the hinge point of the rod assembly 20 and the cleaning head 30 at the pivot 200a to a height at least one radius of the rod assembly 20 higher than the upper surface of the cleaning head 30. This reduces the ability of the cleaning head 30 to pass through narrow spaces. In order to ensure the ability of the cleaning head 30 to pass through narrow spaces with limited height, the hinge point of the rod assembly 20 and the cleaning head 30 at the pivot 200a can only be limited to a height lower than the upper surface of the cleaning head 30 by at least one radius of the rod assembly 20. In this way, the angle between the rod assembly 20 and the cleaning head 30 on the normal section perpendicular to the surface to be cleaned is continuously adjustable within the range of 10 degrees to 195 degrees. When the rod assembly 20 is pivoted about the hinged end of the pivot member 200a to abut against the edge closest to the top upper surface of the cleaning head 30, the angle between the rod assembly 20 and the cleaning head 30 on the normal section perpendicular to the surface to be cleaned is 5 degrees. The case where the angle between the rod assembly 20 and the cleaning head 30 on the normal section perpendicular to the surface to be cleaned is 195 degrees is the same as described above and will not be repeated here.

[0067] Specifically, such as Figure 1 As shown, in one implementation scenario, in a non-use state, the handle 10 and the rod assembly 20 can stand stably on the cleaning head 30 .

[0068] The handle 10 and the cleaning head 30 are located on the same side of the rod assembly 20; when the angle between the rod assembly 20 and the cleaning head 30 is approximately 0 degrees and approximately 180 degrees, the overall height of the cleaning device is as low as possible, thereby making it convenient to store the cleaning head 30 when the angle between the rod assembly 20 and the cleaning head 30 is approximately 0 degrees, and making it convenient to use the handle 10 and the rod assembly 20 to carry out cleaning operations in a small space with limited height. Such small spaces with limited height include but are not limited to the bottom of a bed, the bottom of a sofa, the bottom of a cabinet, the bottom of a table, etc. When the angle between the rod assembly 20 and the cleaning head 30 is approximately 180 degrees, the highest point of the handle 10 is lower than the highest point of the cleaning head 30. Simply put, the total height of the handle does not exceed the thickness of the cleaning head at this time.

[0069] The height of the handle 10 can be adjusted by adjusting the angle between the rod assembly 20 and the cleaning head 30, thereby adapting to the user's height and preferred operating height and / or operating method, and improving the grip of the handle. In a preferred embodiment, different operating modes can also be adjusted by adjusting the angle between the rod assembly 20 and the cleaning head 30.

[0070] In one or more optional embodiments, as Figure 1 As shown, the rod assembly 20 includes a rod body 200 and a pivot member 200a that allows the rod assembly 20 and the cleaning head 30 to pivot relative to each other. The handle 10 is sleeved on one end of the rod body 200, and the pivot member 200a is provided at the other end of the rod body 200 away from the handle 10. The rod body 200 can rotate around the pivot member 200a at any angle using its own axis as the rotation axis. Since the rod body 200 can rotate around the pivot member 200a at any angle, as shown in the figure, the axis of the rod assembly 20 and the straight line at the front end edge of the cleaning head 30 can form an angle of 45-135 degrees. When the pivoting member 200a is pivoted about the hinged end on a normal section perpendicular to the surface to be cleaned, the rod body 200 can also be rotated about the pivoting member 200 with its own axis as the rotation axis. This allows the user to flexibly adjust the forward or backward angle of the cleaning head 30, allowing the user to freely use the cleaning device to clean any area on the surface to be cleaned. It should also be noted that because the handle 10 is sleeved on the rod body 200, the handle 10 and the rod body 200 cannot rotate relative to each other. The shape of the handle 10 allows the user to more conveniently and quickly rotate the rod body 200 about the pivoting member 200a by holding the handle 10.

[0071] In one or more optional embodiments, as Figure 4-8 As shown, the top opening cover of the handle body 100 is provided with a panel assembly 110, and the panel assembly 110 includes a panel body 111 and a button 112. Specifically, Figure 5 、 Figure 6 、 Figure 7 FIG is an exploded view of the handle 10. Figure 4-7 As shown, the panel assembly 110 includes a panel body 111. The panel body 111 is shaped like a runway when covering the top opening of the handle body 100. A through hole 111a is provided on the end of the panel body 111 near the grip 102a. The button 112 passes through the through hole 111a and becomes flush with the panel body 111. Pressing the button 112 causes the button 112 to move up and down perpendicular to the surface of the panel body 111. When viewed from the top of the handle 10, the overall appearance of the panel assembly 110 is runway-shaped. The panel assembly 110 is sealed with the top opening of the blocking hook 102b to prevent water and dust from entering the cavity within the handle body 100.

[0072] In one or some optional embodiments, the panel body 111 is projected into a runway shape at the top opening of the handle body 100, and a runway-shaped abutment flange 111b is extended downward from one end of the panel body 111 toward the top opening of the handle body 100, as shown in FIG. Figure 4-7 As shown, the abutting flange 111b is sealed and clamped on the surrounding wall of the top opening of the handle body 100, which can prevent external water from entering the interior of the blocking hook 102b through the gap between the panel body 111 and the top opening of the handle body 100.

[0073] Furthermore, a plurality of snaps 111c are arranged at intervals on the outer surface of the connection between the runway-shaped abutting flange 111b and the top opening of the handle body 100, and a plurality of slots corresponding to the snaps 111c are provided on the inner wall of the surrounding wall at the top opening of the handle body 100 (not marked in the drawings). When the panel body 111 is sealed and fastened to the top opening of the handle body 100, the snaps 111c are fastened in the slots. Preferably, a buckle 111c is provided on the outer surface of the abutting flange 111b closest to the through hole 111a, and a slot corresponding to the buckle 111c is provided on the inner wall of the surrounding wall closest to the through hole 111a at the top opening of the handle body 100. When the panel body 111 is sealed and fastened to the top opening of the handle body 100, the buckle 111c needs to be fastened in the slot first, and then the other buckles 111c need to be fastened in the other slots in sequence along the runway-shaped surrounding wall.

[0074] Further, if Figure 5As shown, a mounting post 111d is further extended downward from the inside of the runway-shaped abutting flange 111b of the panel body 111. The mounting post 111d is arranged beside another arc of the runway-shaped abutting flange 111b of the panel body 111 in addition to the through hole 111a. The front end of the mounting post 111d extends below the surrounding wall. A through hole or a blind hole pointing to the through hole 111a is provided at the front end of the mounting post 111d. An opening is provided at one end of the through hole or blind hole pointing to the surrounding wall. A panel locking hole 102b2 is provided on the surrounding wall of the top opening of the handle body 100. The panel locking hole 102b2 is opposite to the opening of the through hole or blind hole. A screw is screwed into the panel locking hole 102b2, and the other end of the screw is threadedly connected to the through hole or blind hole, thereby tightly sealing the panel body 111 and fixing it to the top opening of the handle body 100. One end of the runway-shaped panel body 111 is fastened to the surrounding wall with a snap fastener, and the other end is fastened with screws through the panel locking hole 102b2 on the surrounding wall. The runway-shaped abutting flange 111b is fastened to the slots on the inner wall of the surrounding wall through multiple snap fasteners 111c on all sides, thereby achieving a tight sealing cover of the panel body 111 fixed to the top opening of the handle body 100, further improving the reliability of the sealing cover connection between the panel body 111 and the top opening of the handle body 100.

[0075] In one or more optional embodiments, when viewed from the side of the illustrated handle, the blocking hook 102b and the grip 102a of the handle body 100 together form an inverted L-shaped structure, with the panel assembly 110 positioned at the long bottom edge of the inverted L-shape. The bottom wall of the blocking hook is provided with multiple speaker holes 102b1, with a speaker 104 mounted directly above the speaker holes 102b1 within the blocking hook. The connection between the blocking hook 102b and the grip 102a is formed by a circular arc. When the user grips the handle 10, they can lift their thumb to conveniently press the button 112 to activate / switch the cleaning device or adjust its operating mode. Simultaneously, the cleaning device immediately plays a corresponding voice message through the speaker to inform the user of the current operating mode and status. Of course, when the cleaning device switches from operating on the internal battery to charging, the speaker will play "Charging." If the cleaning device is suddenly unplugged from the power adapter while charging but not fully charged, the speaker will play "Charging Interrupted." The voice playback entries for other various states will not be described here one by one.

[0076] In one or more optional embodiments, as Figure 2-3As shown, the axis of the grip portion 102 forms a certain angle with the axis of the straight tube portion 101, and the angle range is 61-79 degrees, preferably 66-69 degrees, and more preferably 67-68 degrees. When the user holds the handheld portion 102 at a certain angle to the axis of the straight tube portion 101, the slightly forward angle allows the user to push the cleaning head 30 of the cleaning device forward. This slight angle allows the user to easily push the handheld portion 102 forward to push the cleaning head 30 forward, making it easier. When the user pulls back the cleaning head 30 of the cleaning device, the user can easily hook the handheld portion 102 with at least one of the first four fingers of the palm, easily pulling back the cleaning head 30 while preventing the handle 10 from falling out of the user's hand. In order to adapt to the use of "lying flat" as much as possible, that is, when the angle between the rod body assembly 20 and the cleaning head 30 is about 180 degrees, that is, when "lying flat" at 180 degrees is achieved, the highest point of the panel assembly 110 at the top of the blocking hook 102b of the handle 10 is no higher than the height of the cleaning head 30. This slightly forward angle can slightly increase the length of the handheld portion 102 of the handle 10 without increasing the height of the handle 10 when lying flat, making it more comfortable for users to hold and able to adapt to users with larger hands. Of course, users with smaller hands, such as children, only need to hold a part of the handheld portion 102.

[0077] In one or more optional embodiments, as Figure 2-4 As shown, the side shape of the blocking hook 102b is an inverted L-shaped straight strip with a long side, and the projection viewing angle of the blocking hook 102b toward the straight tube portion 101 is a runway shape.

[0078] Specifically, Figure 2 A three-dimensional diagram of the handle. Figure 3 is a three-dimensional diagram of the handle from another perspective. Figure 2-3 As shown, the handle 10 includes a handle body 100. The main body of the handle body 100 is a grip portion 102, which includes a grip handle 102a. The inverted L-shaped structure of the grip handle 102a prevents the grip handle 102a from slipping when the user (i.e., the operator) grasps the handle body 100. Preferably, a blocking hook 102b has a trapezoidal cross-section and is wedge-shaped (not shown) connected to the end of the handle portion 102. Specifically, the blocking hook 102b increases in cross-sectional area toward the end and bulges more toward the cleaning head 30. The inverted L-shaped blocking hook 102b allows the user to easily hook the grip portion 102 with at least one of the first four fingers of the palm when retracting the cleaning head 30, thereby preventing the grip handle 102a of the handle body 100 from slipping when the user (i.e., the operator) grasps the handle portion 102a.

[0079] In one or more optional embodiments, as Figure 2-4 As shown, the handle 102a has a straight cylindrical shape with a consistent cross section from the bottom to the end on its axis. Figure 2-3 As shown, the grip portion 102 is generally hollow and cylindrical. In a preferred embodiment, the grip portion 102 can be slightly thicker in the middle and tapered at the ends (not shown in the figures) to meet ergonomic requirements. The grip 102a, which is thicker in the middle and thinner at the ends, provides a more comfortable grip for the user, preventing fatigue after prolonged use.

[0080] In a specific embodiment, Figure 4 、 Figure 6-8 As shown, the straight tube portion 101 includes a sleeve portion 101a that is sleeved and fixedly engaged with the interior of the rod assembly 20, and an exposed portion 101b connected to the sleeve portion and exposed to the outside of the end of the rod assembly 20. The sleeve portion 101a is provided with a plurality of guide structures (not shown in the drawings) for guiding and cooperating with the rod assembly 20. The sleeve portion 101a is a hollow tubular structure through which a control harness 201 is passed. The use of the guide structures allows for rapid guided docking of the handle 10 and the rod assembly 20, making the docking process of the handle 10 and the rod assembly 20 more efficient during the production of the cleaning device, reducing the skill requirements of the operator, and simplifying the separation of the handle 10 from the rod assembly 20 when the user maintains the internal components of the handle 10.

[0081] Specifically, Figure 3The figure shows an exploded view of the handle 10 mounted on the rod assembly 20 of a cleaning device. The straight cylindrical portion 101, which engages with the rod assembly 20, comprises a sleeve portion 101a that fits within the rod assembly 20 and engages therewith, and an exposed portion 101b connected to the sleeve portion 101a and exposed to the outside of the end of the rod assembly 20. The sleeve portion 101a is provided with several guide structures (not shown) that guide the rod assembly 20. These guide structures may be guide grooves and / or guide protrusions. The main body of the sleeve portion 101a is a generally hollow tubular structure, through which passes the control wiring harness 201 that electrically connects the rod assembly 20 to the electronic components of the handle 10. The outer diameter and shape of the exposed portion 101b are compatible with the rod assembly 20, so that when the sleeve portion 101a is sleeved and secured within the rod assembly 20, the exposed portion 101b and the rod assembly 20 appear to be one piece. At the same time, this visual sense of unity is not limited to the user's visual experience. When the user touches the surface of the rod assembly 20 upwards, this silky feeling can extend all the way to the exposed part 101b of the handle. When the user moves and carries the cleaning device, he can still feel the sense of unity between the cleaning device rod assembly 20 and the handle 10 by touch.

[0082] In one or some optional embodiments, specifically, Figure 4 After the handle 10 is installed on the rod assembly 20 of the cleaning device Figure 2 In the A-axis planing view, Figure 5 This is an exploded view of the handle 10 from one perspective. Figure 6 FIG. 1 is an exploded view of the handle 10 from another perspective. Figure 4 、 Figure 6-8As shown, the exposed portion 101b may further include a charging port 101b2 and a second speaker hole (not shown) on its outer circumference away from the grip portion 102. The blocking hook 102b has multiple speaker holes 102b1 located near the cleaning head 30. Either or both of the speaker holes 102b1 and the second speaker hole may be provided. A second speaker hole is provided on the outer peripheral surface of the exposed portion 101b away from the gripping portion 102, and / or a speaker hole 102b1 is provided on the blocking hook 102b in a direction close to the cleaning head 30, so that the control panel can instantly play the usage prompt voice played to the user through the second speaker hole and / or the speaker hole 102b1. At the same time, since the exposed portion 101b and the blocking hook 102b are away from the cleaning head 30, water can be further prevented from falling into the handle 10 through the second speaker hole and / or the speaker hole 102b1, thereby preventing water from entering the rod body assembly 20 and the handle 10 and affecting the operation of the cleaning device. A charging interface 101b2 is provided on the outer peripheral surface of the exposed portion 101b away from the gripping portion 102. The charging interface 101b2 itself has a waterproof function, allowing the user to conveniently use a charger to charge the battery pack provided in the handle 10 or the rod body assembly 20 through the charging interface 101b2 to provide power energy for the operation of the cleaning device.

[0083] In a specific embodiment, Figure 7 This is an exploded diagram of the handle where the second control panel is first installed on the mounting bracket and then installed into the blocking hook. Figure 8 For the handle Figure 7 Partial cross-sectional view from perspective, Figure 9 For Figure 2 Cross-sectional view in the B direction. Figure 4-8 As shown, a control board 103 is disposed within the straight portion 101 of the straight body 120. The control board 103 is snapped into the straight portion 101. An end cap 121 is provided on the outer end surface of the straight portion 101, with a decorative sticker 123 attached to the exposed surface of the end cap 121. An audio cable (not shown) is connected to the speaker 104, the other end of which passes through the grip 102 and is electrically connected to the control board 103. After docking the handle 10 to the rod assembly 20, the end cap 121 must be opened, the control wiring harness 201 pulled upward from the rod assembly 20, and electrically connected to the control board 103. The audio cable from the speaker 104 is then electrically connected to the control board 103. The control board 103 is then snapped into the straight portion 101. Finally, the end cap 121 is replaced, and the decorative sticker 123 is applied to the exposed surface of the end cap 121. It should be noted that if Figure 7 、 Figure 8As shown, the end cap 121 is provided with a through hole (not shown in the drawings) that allows access to the straight tube portion 101. Furthermore, the decorative surface sticker 123 can also have a built-in flexible circuit. The decorative surface sticker 123 also has a flexible cable (not shown in the drawings) that can pass through the end cap 121 through the through hole to enter the straight tube portion 101 and electrically connect to the control board 103. The user can also trigger functions such as self-cleaning of the cleaning device by lightly touching the decorative surface sticker 123. Furthermore, the decorative surface sticker 123 can also have a built-in NFC tag. The user can use the NFC function to interact with the information stored in the cleaning device by placing their mobile phone close to the decorative surface sticker 123. Furthermore, the control board 103 is also provided with an interface for data transmission at one end near the end cap 121. An external data cable can be electrically connected to the interface through the through hole, allowing the software burned into the control board 103 to be directly upgraded externally, and the control parameters of the cleaning device can also be modified by connecting to a computer or other smart terminal via an external data cable.

[0084] In one or more optional embodiments, as Figure 4-8 As shown, the blocking hook 102b can be fitted with a second control board 116 and a silicone sleeve 114. The silicone sleeve 114 snaps onto the second control board 116 to provide waterproof sealing protection for the second control board 114. The second control board 114 is positioned above the speaker 104 and the audio cable, and is electrically connected to the control board 103 within the straight portion 101 via a wiring harness (not shown) that passes through the grip portion 102. In other words, the silicone sleeve 114 is positioned between the second control board 116 and the panel body 111 to prevent moisture or water from leaking through gaps in the panel body 111, where the buttons 112 and display panel 113 are located, from reaching the second control board 116.

[0085] In one or more optional embodiments, as Figure 4-8 As shown, the bottom wall of the blocking hook 102b is also equipped with a sound cavity enclosure (not shown) that surrounds the speaker 104, as well as a nut standoff (not shown) for securing the second control board 116. The bottom wall, sound cavity enclosure, and the bottom surface of the second control board 116 together form a sound cavity (not shown) that increases the speaker's volume. When assembling the handle 10, the speaker 104 is first placed into the sound cavity enclosed by the sound cavity enclosure. The second control board 116 is then placed over the sound cavity and secured to the bottom wall of the blocking hook 102b using multiple screws. The silicone sleeve 114 is then fastened to the second control board 116 to provide waterproof sealing protection. Finally, the panel body 111 is fastened to the opening of the blocking hook 102b.

[0086] In one or more optional embodiments, as Figure 4-8 As shown, the second control panel 116 is provided with a plurality of lamp beads (not shown in the drawings) and a touch button (not shown in the drawings) on the side facing the panel body 111. The button 112 abuts the silicone sleeve 114, and the silicone sleeve 114 abuts the touch button. The plurality of lamp beads can emit light through the panel body 111 to indicate the power level, working status, and charging status of the cleaning device. Pressing the button 112 can touch the touch button to trigger the corresponding function of the cleaning device. The plurality of lamp beads indicate different working statuses through the panel body 111 with different lights, such as low power, charging, full, normal mode, and strong mode.

[0087] Specifically, such as Figure 4-8 As shown, the speaker 104 is sealed to the sound cavity enclosure of the blocking hook 102b, so that even if water enters the sound cavity through the sound-speaker hole 102b1, it cannot break through the speaker 104 and enter the interior of the handle 10. Even if water enters the interior of the handle 10, the silicone sleeve 114 isolates and seals the second control panel 116, the button 112, and the lamp, so the water cannot reach the second control panel 116, the button 112, and the lamp, and thus cannot affect the normal operation of the cleaning device.

[0088] A second control panel 116 is disposed below the panel body 111. Light beads on the control panel can illuminate through the panel body 111 to indicate to the user the current operating status and alarm status of the cleaning device. Furthermore, the second control panel 116 can also drive a display screen (not shown in the figures), which can graphically display the current operating status and alarm status of the cleaning device through the panel body 111.

[0089] The handle of the present invention provides a variety of interactive functions through the panel assembly 110, and can interact with the user through lighting, graphic display, etc. on the handle.

By providing a mounting bracket, it is possible to avoid directly mounting the second control panel on the bottom wall of the blocking hook. The second control panel can be first mounted on the mounting bracket to form a control component as a whole, and then the mounting bracket can be tightly mounted and connected to the bottom wall of the blocking hook. This can further allow the mounting bracket to bear the possibility that the user may hook the blocking hook with his fingers when using the cleaning device, further reducing the force on the second control panel during the use of the cleaning device, which is beneficial to increasing the service life of the cleaning device and improving the reliability of the handle.

[0091] Further, such as Figure 4-8 As shown, a light-shielding and light-transmitting plate 115 can be further provided between the silicone sleeve 114 and the panel body 111. The light-shielding and light-transmitting plate 115 can cooperate with the multiple light beads of the second control board 116 to further present different colors, shapes, and patterns that can be transmitted through the panel body 111.

The charging hole can be installed with a charging interface 101b2, which is electrically connected to the control board 103. When the charging interface 101b2 is connected to an external power source, the battery pack (not shown in the drawings) in the rod body assembly 20 can be further charged through the control board 103.

[0093] In one or some optional embodiments, the sound hole 101b1 may also be provided on the straight tube portion 101, and the speaker 104 may also be installed in the straight tube portion 101 in the area opposite to the sound hole 101b1. At the same time, a self-cleaning button (not marked in the drawings) may also be provided on the end cover 121. The self-cleaning button may directly reach the self-cleaning button (not marked in the drawings) of the control panel 103. Pressing the self-cleaning button may start the self-cleaning function of the cleaning device.

[0094] For the above embodiment, the button 112 can be used to switch the working mode, for example, to switch between the long-endurance mode and the strong mode. The cleaning head 30 includes a clean water container, a sewage recovery bucket and a cleaning roller assembly. The clean water container is used to store clean water and is connected to the cleaning roller assembly to wet the cleaning roller and further scrub the floor by continuously flushing the roller. The sewage recovery bucket is used to recover the sewage squeezed out from the surface of the cleaning roller. The sewage recovery bucket is connected to the cleaning roller assembly through a sewage pipeline to introduce the sewage squeezed out from the surface of the cleaning roller into the sewage recovery bucket. In a preferred embodiment, the cleaning head 30 also includes a suction assembly, which is used to suck the sewage squeezed out from the surface of the cleaning roller into the sewage recovery bucket. The suction assembly includes a motor and an impeller, and the motor drives the impeller to rotate to generate negative pressure.
