[0088] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0089] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0090] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0091] In this specification, references to "one embodiment," "some embodiments," or simply "embodiment" mean that one or more embodiments of this application include a specific feature, structure, or characteristic described in connection with that embodiment. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. Furthermore, in one or more embodiments, specific features, structures, or characteristics may be combined in any suitable manner.

[0092] As living standards improve, people have increasingly higher requirements for floor cleaning. Currently, the market offers a variety of cleaning equipment, such as vacuum cleaners, floor scrubbers, and steam mops, to meet different cleaning needs.

[0093] Cleaning equipment typically comprises a cleaning component, a body component, and a handle, resulting in a relatively large size and making it difficult to use and store. The cleaning component moves across the surface to be cleaned; the body component connects to the cleaning component and collects the dirt, providing water and suction; the handle connects to the body component and is used by the user to grip and operate the equipment. The internal structures of the cleaning and body components are complex, and their size and relative positions are generally fixed to ensure structural and functional stability. The handle, as the part for the user to grip, has a relatively simple internal structure. Therefore, this application reduces the difficulty of storing the handle and increases its flexibility by modifying its structure, thereby simplifying the use and storage of the cleaning equipment.

[0094] To illustrate the technical solution of this application, the following description is provided in conjunction with specific accompanying drawings and embodiments.

[0095] Please refer to Figures 2 to 18 This application provides a handle for connecting to the body assembly 210 of a cleaning device 200; at least a portion of the handle is rotatable relative to the body assembly 210, and the handle is extendable to change its length.

[0096] Please refer to Figures 2 to 4 The cleaning device 200 with the handle according to the present application embodiment further includes a cleaning component 220 and a body component 210. The cleaning component 220 is used to move on the surface to be cleaned to clean the surface. The body component 210 is rotatably connected to the cleaning component 220 and is used to collect the dirt collected by the cleaning component 220 and to provide clean water and suction to the cleaning component 220. The handle is for the user to hold, and at least part of the handle can be connected relative to the body component 210 so that the user can move the cleaning device 200 by moving the handle.

[0097] Optionally, the cleaning equipment 200 can be a vacuum cleaner, floor scrubber, steam mop, etc.

[0098] When it is necessary to store the handle and the cleaning device 200 with the handle according to the present application embodiment, the length of the handle is adjusted to the shortest; the handle is rotated relative to the body assembly 210 so that the handle is folded relative to the body assembly 210, thereby reducing the space occupied by the handle and reducing the difficulty of storing the handle and the cleaning device 200 with the handle.

[0099] Furthermore, by applying the handle of this embodiment to the cleaning device 200, the flexibility of the cleaning device 200 can be enhanced, making cleaning more effortless. For example, when cleaning a large area, the user can adjust the length of the handle according to the position of the cleaning surface, allowing the user to clean the large area from a single position, making cleaning effortless. As another example, when cleaning surfaces located in low spaces such as under beds, sofas, and tables, the user can rotate the handle relative to the body assembly 210, causing the handle to fold relative to the body assembly 210. This allows the body assembly 210 to lie flat and enter low spaces without the user needing to bend over, making cleaning effortless. Moreover, when the body assembly 210 lies flat in a low space, the user can adjust the length of the handle according to the position of the cleaning surface, allowing the cleaning assembly 220 to enter even narrower spaces.

[0100] The handle provided in the first aspect of this application is telescopically adjustable in length to accommodate users of different heights, and can also rotate relative to the body assembly 210, facilitating the flat cleaning of the body assembly 210 for user convenience. When storing the handle of this application embodiment or the cleaning device 200 with the handle of this application embodiment, the handle is retracted to reduce the volume occupied by the handle, thereby reducing the storage difficulty of the handle and the cleaning device 200 with the handle.

[0101] Please refer to Figures 2 to 4 In some embodiments, the handle includes a first lever 1 and a second lever 2, the first lever 1 being connected to the body assembly 210, and the second lever 2 being rotatably connected to the first lever 1.

[0102] In the above embodiment, the second rod 2 is rotatably connected to the first rod 1, so that the second rod 2 can rotate relative to the fuselage assembly 210.

[0103] It should be noted that in the above embodiment, the rotation axes of the first rod 1 and the second rod 2 intersect the length direction of the second rod 2.

[0104] In the above embodiment, when the second rod 2 rotates relative to the first rod 1, the handle can be folded to reduce the handle volume.

[0105] In some embodiments, the second rod 2 is provided with a rotating shaft 21 and two oppositely arranged connecting parts 22, which are respectively connected to the two ends of the rotating shaft 21. The first rod 1 is rotatably sleeved on the rotating shaft 21, so that the first rod 1 and the second rod 2 can rotate relative to each other. In the above embodiments, the first rod 1 and the second rod 2 can rotate 360° relative to each other.

[0106] Please refer to Figure 5 and Figure 6 In other embodiments, the second rod 2 is further provided with a limiting part 23 located between the two connecting parts 22. The limiting part 23 can stop the first rod 1 to limit the angle at which the first rod 1 can rotate relative to the second rod 2, thereby improving the control accuracy of the handle. In the above embodiments, the first rod 1 and the second rod 2 can rotate relative to each other by 90°.

[0107] Please refer to Figure 5 The second rod 2 has a grip 24 at the end opposite to the first rod 1. The grip 24 has a ring-shaped structure that can better fit the curve of the palm and provide a more comfortable grip so that the user can hold it.

[0108] It should be noted that "the handle can be extended to change the length of the handle" means that: the first lever 1 can be extended to change the length of the handle; or, the second lever 2 can be extended to change the length of the handle; or, both the first lever 1 and the second lever 2 can be extended to change the length of the handle.

[0109] It should be noted that "the first rod 1 is telescopic" means that the first rod 1 includes multiple telescopic segments connected sequentially along its length, and adjacent telescopic segments at least partially overlap. The length of the first rod 1 can be changed by altering the overlap length of adjacent telescopic segments. Similarly, "the second rod 2 is telescopic" means that the second rod 2 includes multiple telescopic segments connected sequentially along its length, and adjacent telescopic segments at least partially overlap. The length of the second rod 2 can be changed by altering the overlap length of adjacent telescopic segments.

[0110] Please refer to Figures 2 to 18In some embodiments, the handle has a first locking structure 3. When the first locking structure 3 is locked, the rotation of the handle relative to the body assembly 210 is restricted. When the first locking structure 3 is unlocked, at least part of the handle can rotate relative to the body assembly 210.

[0111] When using the handle and the cleaning device 200 with the handle according to the embodiments of this application, the first locking structure 3 locks the first rod 1 and the second rod 2, preventing the first rod 1 and the second rod 2 from rotating relative to each other. This fixes the relative positions of the first rod 1 and the second rod 2, thus stabilizing the handle structure. When it is necessary to store the handle and the cleaning device 200 with the handle according to the embodiments of this application, the first locking structure 3 is released from locking the second rod 2 and the first rod 1, and the second rod 2 is rotated to fold the handle, thereby reducing the space occupied by the handle and reducing the difficulty of storing the handle and the cleaning device 200 with the handle.

[0112] It should be noted that when the first locking structure 3 is in the locked state, the rotation of the handle relative to the body assembly 210 is restricted, meaning that: the first locking structure 3 is set on the second rod 2, and when the first locking structure 3 is inserted into the first rod 1, it can prevent the first rod 1 from rotating relative to the second rod 2; or, the first locking structure 3 is set on the first rod 1, and when the first locking structure 3 is inserted into the second rod 2, it can prevent the first rod 1 from rotating relative to the second rod 2.

[0113] Please refer to Figures 2 to 18 In some embodiments, the handle has a second locking structure 4. When the second locking structure 4 is in a locked state, the extension and retraction of the handle are restricted; when the second locking structure 4 is in an unlocked state, the handle can extend and retract.

[0114] It should be noted that when the second locking structure 4 is in the locked state, the extension and retraction of the handle is restricted; when the second locking structure 4 is in the unlocked state, the handle is extendable because the second rod 2 includes multiple telescopic segments connected sequentially along its length, and adjacent telescopic segments at least partially overlap. The length of the second rod 2 can be changed by altering the overlap length of adjacent telescopic segments. When the second locking structure 4 locks the second rod 2, the relative positions of adjacent telescopic segments are fixed, ensuring that the overlap length of adjacent telescopic segments remains constant, i.e., the length of the second rod 2 remains unchanged. When the second locking structure 4 releases the second rod 2, adjacent telescopic segments can move relative to each other, changing the overlap length of adjacent telescopic segments to alter the length of the second rod 2.

[0115] When using the handle and the cleaning device 200 with the handle according to this embodiment, the second locking structure 4 locks the second rod 2 so that the length of the second rod 2 does not change, thereby stabilizing the handle structure. When it is necessary to store the handle and the cleaning device 200 with the handle according to this embodiment, the second locking structure 4 is unlocked, and the length of the second rod 2 is adjusted to its shortest length.

[0116] Please refer to Figures 7 to 16 In some embodiments, the first locking structure 3 includes a first locking member 31 and a driving component 32, with the first locking member 31 connected to the driving component 32. When the first locking structure 3 is in the locked state, the driving component 32 moves the first locking member 31 to the unlocked position. When the first locking structure 3 is in the unlocked state, the driving component 32 moves the first locking member 31 to the unlocked position.

[0117] Please refer to Figures 7 to 16 In some embodiments, the drive assembly 32 is disposed on the second rod 2, and the first rod 1 has a lock hole 11. When the first locking structure 3 is in the locked state, the drive assembly 32 drives the first locking member 31 to insert into the lock hole 11. When the first locking structure 3 is in the unlocked state, the drive assembly 32 drives the first locking member 31 to disengage from the lock hole 11.

[0118] In the above embodiment, when the first locking member 31 is inserted into the lock hole 11, the first rod 1 and the second rod 2 will not rotate relative to each other.

[0119] In the above embodiments, the drive component 32 is a manual component or a semi-automatic component. The user can drive the first locking member 31 to be inserted into the lock hole 11 and / or drive the first locking member 31 to be disengaged from the lock hole 11 by operating the drive component 32.

[0120] It is understandable that when the handle is applied to the cleaning device 200, the rotating connection joint between the second lever 2 and the first lever 1 is located at a lower position in the cleaning device 200. In the above embodiment, the drive assembly 32 can provide driving force to the first locking member 31 to extend the operating distance of the first locking member 31. This can be achieved by setting the drive assembly 32 on the handle at a position close to the user, such as the grip portion 24, so that the user can operate it without having to bend over to move the first locking member 31.

[0121] Please refer to Figure 10In some embodiments, the drive assembly 32 includes a first elastic element 321 and a drive input terminal 322. The first elastic element 321 is connected to the first locking element 31, and the drive input terminal 322 is connected to the first locking element 31. When the first locking structure 3 is in the locked state, the first elastic element 321 and / or the drive input terminal 322 drive the first locking element 31 to insert into the lock hole 11. When the first locking structure 3 is in the unlocked state, the first elastic element 321 and / or the drive input terminal 322 drive the first locking element 31 to disengage from the lock hole 11.

[0122] In the above embodiment, when the first locking member 31 is opposite to the lock hole 11 and the user does not operate the drive input terminal 322, the first elastic member 321 is in its natural state. The first elastic member 321 drives the first locking member 31 to move into the lock hole 11, so that the first locking structure 3 locks the second rod 2 and the first rod 1. When the user operates the drive input terminal 322, the drive input terminal 322 drives the first locking member 31 to move. The first locking member 31 presses against the first elastic member 321, and the drive input terminal 322 drives the first locking member 31 to overcome the elastic force of the first elastic member 321 and move to disengage from the lock hole 11, so as to release the lock on the second rod 2 and the first rod 1, so that the second rod 2 and the first rod 1 can rotate relative to each other. When it is necessary to lock the second rod 2 and the first rod 1 again, the second rod 2 and the first rod 1 need to be rotated relative to each other until the first locking member 31 is opposite to the lock hole 11. Then the user stops operating the drive input terminal 322, so that the force applied by the drive input terminal 322 to the first locking member 31 is canceled, the first elastic member 321 returns to its natural state and drives the first locking member 31 to move and be inserted into the lock hole 11.

[0123] In some embodiments, multiple lock holes 11 are provided, and the multiple lock holes 11 are distributed circumferentially along the rotating shaft 21. By inserting the first locking member 31 into different lock holes 11, the second rod 2 and the first rod 1 can be locked in different relative positions.

[0124] It should be noted that the first elastic element 321 is connected to both the first locking element 31 and the second rod 2, and can be used as follows: Figure 10 The structure in the embodiment shown is as follows: the first locking member 31 is slidably housed in the second rod 2, the second rod 2 is provided with a first receiving groove 25, a portion of the first locking member 31 is slidably inserted through the first receiving groove 25, the first elastic member 321 is housed in the first receiving groove 25, and one end of the first elastic member 321 is connected to the first locking member 31, and the other end of the first elastic member 321 is connected to the inner wall of the first receiving groove 25.

[0125] It should be noted that the first elastic element 321 is connected to both the first locking element 31 and the second rod 2, and can also be as follows: Figure 11In the illustrated embodiment, the first locking member 31 is slidably housed within the second rod 2. One end of the first elastic member 321 is connected to the end of the first locking member 31 facing away from the locking position, and the other end of the first elastic member 321 is connected to the second rod 2. To enhance the connection between the first locking member 31 and the first elastic member 321, a second receiving groove 311 can be formed on the first locking member 31, and a portion of the first elastic member 321 can be housed within the second receiving groove 311.

[0126] In other embodiments, when the first locking structure 3 locks the second rod 2 and the first rod 1, the drive input end 322 drives the first locking member 31 to insert into the lock hole 11, and the first rod 1 and the second rod 2 cannot rotate relative to each other. When the first locking structure 3 releases the lock on the second rod 2 and the first rod 1, the first elastic member 321 drives the first locking member 31 to disengage from the lock hole 11, and the first rod 1 and the second rod 2 can rotate relative to each other.

[0127] In the above embodiment, the first elastic element 321 is in its natural state in the initial state. When it is necessary to lock the first rod 1 and the second rod 2, the first rod 1 and the second rod 2 rotate relative to each other until the first locking element 31 is opposite to the lock hole 11. The user operates the drive input terminal 322, which drives the first locking element 31 to move. The first locking element 31 presses against the first elastic element 321, and the drive input terminal 322 drives the first locking element 31 to overcome the elastic force of the first elastic element 321 and move to be inserted into the lock hole 11. When it is necessary to release the lock on the second rod 2 and the first rod 1, the user no longer operates the drive input terminal 322, so that the force applied by the drive input terminal 322 to the first locking element 31 is canceled. The first elastic element 321 returns to its natural state and drives the first locking element 31 to move and disengage from the lock hole 11, so that the second rod 2 and the first rod 1 can rotate relative to each other.

[0128] The above-described embodiment, by setting the first elastic element 321 and utilizing the reset function of the first elastic element 321, can reduce the number of operation steps required by the user, thereby saving the user's time and effort; and the reset function of the first elastic element 321 can also ensure that the first locking element 31 always remains in the correct position, preventing the first locking element 31 from being misaligned due to external force or misoperation.

[0129] In some embodiments, the drive input 322 may include a drive lever connected to the first locking member 31, with the end of the drive lever away from the first locking member 31 protruding from the second lever 2 for easy gripping or pressing by the user.

[0130] The driver input 322 can also be other structures, such as... Figures 10 to 16In the illustrated embodiment, the drive input end 322 includes a rope 3221 and a first reel 3222. The first reel 3222 is rotatably mounted on the second rod 2. One end of the rope 3221 is connected to the first reel 3222, and the other end of the rope 3221 is connected to the first locking member 31. Under the action of the first elastic member 321, the first locking member 31 can be inserted into the lock hole 11. When the first reel 3222 winds up the rope 3221, the rope 3221 can drive the first locking member 31 to overcome the elastic force of the first elastic member 321 and disengage from the lock hole 11.

[0131] In the above embodiment, the user can wind up the rope 3221 by rotating the first reel 3222, so that the rope 3221 pulls the first locking member 31, thereby causing the first locking member 31 to overcome the elastic force of the first elastic member 321 and disengage from the lock hole 11.

[0132] In the above embodiment, the rotation axis of the first reel 3222 may protrude from the second rod 2, so that the user can hold and rotate the first reel 3222.

[0133] Please refer to Figures 14 to 16 In other embodiments, the drive input terminal 322 also includes a first trigger 3223, which can drive the first reel 3222 to wind up the rope 3221 by triggering the first trigger 3223.

[0134] It should be noted that the first trigger 3223 can be a button, toggle switch, wrench, knob, or other trigger with a triggering function.

[0135] In the above embodiment, the first trigger 3223 is movably disposed on the second rod 2, specifically on the grip portion 24.

[0136] Please refer to Figures 14 to 16 In some embodiments, the drive input terminal 322 further includes a driven wheel 3224 and a rack 3225. The driven wheel 3224 is coaxially arranged with the first winding reel 3222. The first trigger 3223 can drive the rack 3225 to move, and the rack 3225 and the driven wheel 3224 mesh.

[0137] In the above embodiment, taking the first trigger 3223 as a button as an example, pressing the first trigger 3223 can drive the first reel 3222 to rotate and wind up the rope 3221. When the user stops pressing the first trigger 3223, the rope 3221 is unwound from the first reel 3222 under the drive of the first elastic member 321, which drives the first reel 3222 and the driven wheel 3224 to rotate, thereby driving the rack 3225 to move until the first trigger 3223 resets.

[0138] With the above settings, it is easier for the user to unlock the first lever 1 and the second lever 2.

[0139] Please refer to Figure 16 In some embodiments, the drive input end 322 further includes a lever 3226, which is rotatably mounted on the second rod 2. The lever 3226 has a first end 32261 and a second end 32262 located on opposite sides of its own axis of rotation. The first end 32261 is located on the side of the second end 32262 closer to the first locking member 31. A rope 3221 is sleeved on the lever 3226.

[0140] In the above embodiment, the first end 32261 is connected to the first locking member 31 via a rope 3221, and the second end 32262 is connected to the first reel 3222 via a rope 3221. When the first reel 3222 winds up the rope 3221, the rope 3221 can slide relative to the lever 3226, causing the lever 3226 to rotate. By setting the lever 3226, the extension direction of the rope 3221 can be changed so that the rope 3221 can adapt to the shape of the handle.

[0141] Please refer to Figure 16 In some embodiments, the distance from the first end 32261 to the axis of rotation of the lever 3226 is greater than the distance from the second end 32262 to the axis of rotation of the lever 3226.

[0142] The lever principle of 3226 can be understood as follows: Design a lever 3226 such that the length of the lever arm (input end) is less than the length of the resistance arm (output end). When a small displacement occurs at the input end, due to the amplification effect of the lever 3226, a larger displacement will occur at the output end.

[0143] Therefore, in the above embodiment, since the distance from the first end 32261 to the rotation axis of the lever 3226 is greater than the distance from the second end 32262 to the rotation axis of the lever 3226, when the second end 32262 produces a small displacement, under the amplification effect of the lever 3226, the first end 32261 will produce a large displacement to amplify the stroke of the first end 32261.

[0144] Please refer to Figure 17 and Figure 18 In some embodiments, the second rod 2 is telescopic to change the length of the handle, the handle has a second locking mechanism, and a second locking structure 4 is disposed on the second rod 2; when the second locking mechanism is in the locked state, the telescopic extension of the second rod 2 is restricted; when the second locking mechanism is in the unlocked state, the second rod 2 is telescopic.

[0145] In the above embodiment, the second rod 2 includes multiple telescopic sections; the second locking structure 4 includes a second locking member 41. When the second locking structure 4 locks the second rod 2, the second locking member 41 is respectively inserted into at least two telescopic sections; when the second locking structure 4 releases the second rod 2, the second locking member 41 disengages from at least one of the at least two telescopic sections.

[0146] In the above embodiment, two adjacent telescopic segments are slidably connected, and the two adjacent telescopic segments at least partially overlap. When the second locking member 41 is respectively inserted into at least two telescopic segments, the second rod 2 is locked, the relative position of the two adjacent telescopic segments is fixed, and the overlap length of the two adjacent telescopic segments remains fixed, so that the length of the second rod 2 remains fixed. When the second locking member 41 disengages from at least one of the at least two telescopic segments, the two adjacent telescopic segments can move relative to each other, the second rod 2 is released, and the overlap length of the two adjacent telescopic segments changes, so that the length of the second rod 2 becomes variable.

[0147] In some embodiments, one of two adjacent telescopic segments is slidably fitted around the periphery of the other, one of the two adjacent telescopic segments is provided with a first clearance through hole 271, and the other of the two adjacent telescopic segments is provided with a first slot 261.

[0148] In the above embodiment, one of two adjacent telescopic segments can be slidably fitted around the periphery of the other, which can enhance the connection between the two adjacent telescopic segments and thus enhance the structural stability of the second rod 2. Furthermore, the slidable fit of one of the two adjacent telescopic segments around the periphery of the other reduces the space occupied by the second rod 2 when its length is reduced to its shortest.

[0149] Please refer to Figure 17 and Figure 18 In some embodiments, when the second locking structure 4 locks the second rod 2, the second locking member 41 passes through the first clearance hole 271 and is inserted into the first slot 261. When the second locking structure 4 releases the second rod 2, the second locking member 41 at least disengages from the first slot 261.

[0150] Please refer to Figure 17 and Figure 18 In some embodiments, the second locking structure 4 further includes a second elastic member 42, which is connected to the second locking member 41 and the second rod 2. When the second locking structure 4 locks the second rod 2, the second elastic member 42 drives the second locking member 41 to pass through the first clearance hole 271 and insert into the first slot 261. When the second locking structure 4 releases the second rod 2, the second locking member 41 overcomes the elastic force of the second elastic member 42 and disengages from the first slot 261.

[0151] In the above embodiment, when the second locking structure 4 locks the second rod 2, the second elastic member 42 is in its natural state. The second elastic member 42 drives the second locking member 41 through the first clearance hole 271 and into the first slot 261, thus locking the second rod 2. The user can drive the second locking member 41 to move it and compress the second elastic member 42, causing the second locking member 41 to overcome the elastic force of the second elastic member 42 and disengage from the first slot 261, thereby unlocking the second rod 2. When the user no longer drives the second locking member 41, the first elastic member 321 returns to its natural state and drives the second locking member 41 through the first clearance hole 271 and into the first slot 261, thus locking the second rod 2 again.

[0152] Please refer to Figure 17 and Figure 18 In some embodiments, there are two telescopic sections, namely a first telescopic section 26 and a second telescopic section 27. The first telescopic section 26 is rotatably connected to the first rod 1. The first telescopic section 26 is slidably sleeved on the outer periphery of the second telescopic section 27, or the second telescopic section 27 is slidably sleeved on the outer periphery of the first telescopic section 26.

[0153] In the above embodiment, the first telescopic section 26 is rotatably connected to the first rod 1, the second telescopic section 27 is closer to the user, and the second elastic member 42 is connected to the second locking member 41 and the second telescopic section 27 respectively. When the second rod 2 retracts, the second elastic member 42 and the second locking member 41 can move with the second telescopic section 27, so that the second locking member 41 always remains in a position closer to the user, so that the user can move the second locking member 41.

[0154] Optionally, the second locking member 41 may be provided on the outer wall of the second telescopic section 27 to facilitate the user's movement of the second locking member 41.

[0155] In the above embodiment, the first telescopic section 26 is slidably fitted onto the outer periphery of the second telescopic section 27. A first clearance through hole 271 is provided on the first telescopic section 26, and a first slot 261 is provided on the second telescopic section 27. Multiple first clearance through holes 271 are provided, and these holes are spaced apart along the length of the second rod 2. This arrangement allows the second rod 2 to have several length settings.

[0156] In the above embodiment, the second telescopic section 27 is slidably sleeved on the outer periphery of the first telescopic section 26, the first clearance through hole 271 is provided on the second telescopic section 27, and the first slot 261 is provided on the first telescopic section 26. Multiple first slots 261 are provided, and the multiple first slots 261 are spaced apart along the length direction of the second rod 2. Through the above arrangement, the length of the second rod 2 has several increments.

[0157] Please refer to Figure 17 and Figure 18 Optionally, the second locking member 41 can be housed within the second telescopic section 27. The second locking structure 4 also includes a second trigger member 43, which is connected to the second locking member 41. When the second locking structure 4 locks the second rod 2, the second elastic member 42 causes the second trigger member 43 to protrude from the second telescopic section 27.

[0158] Optionally, the second trigger 43 can be a button, toggle switch, wrench, knob, or other trigger with a triggering function.

[0159] In the above embodiment, when the second locking structure 4 locks the second rod 2, the second elastic member 42 is in its natural state. The second elastic member 42 drives the second locking member 41 to pass through the first clearance hole 271 and insert into the first slot 261, thereby locking the second rod 2. The second elastic member 42 also drives the second trigger member 43 to protrude from the second telescopic section 27. Taking the second trigger member 43 as a button as an example, pressing the second trigger member 43 will move the second locking member 41 and compress the second elastic member 42, causing the second locking member 41 to overcome the elastic force of the second elastic member 42 and disengage from the first slot 261, thus unlocking the second rod 2. When the user stops pressing the second trigger member 43, the first elastic member 321 returns to its natural state and drives the second locking member 41 to pass through the first clearance hole 271 and insert into the first slot 261, thereby locking the second rod 2 again.

[0160] With the above configuration, the second locking member 41 can be housed in the second telescopic section 27 to reduce the space occupied by the second rod 2 so that the handle can be stored. The second locking member 41 can also be housed in the second telescopic section 27 to reduce the driving area of ​​the second locking member 41, thereby reducing the possibility of the second locking member 41 being accidentally triggered.

[0161] Please refer to Figure 17 and Figure 18 In some embodiments, the second locking member 41 is rotatably connected to the second telescopic section 27. The second locking member 41 has a first section and a second section located on opposite sides of its own axis of rotation. The first section is connected to the second trigger member 43, and the second section is provided with a card block that can be inserted into the first card slot 261.

[0162] In the above embodiment, when the second elastic member 42 is in its natural state, it can drive the second locking member 41 to rotate, causing the locking block to pass through the first clearance hole 271 and be inserted into the first slot 261. When the user presses the second trigger member 43, the second locking member 41 rotates under the action of the second trigger member 43, squeezing or stretching the second elastic member 42. When the user stops pressing the second trigger member 43, the first elastic member 321 returns to its natural state and drives the second locking member 41 to rotate until the locking block passes through the first clearance hole 271 and is inserted into the first slot 261, causing the second rod 2 to lock again.

[0163] The above-described embodiment, by setting the second elastic element 42 and utilizing the reset function of the second elastic element 42, can reduce the number of operation steps required by the user, thereby saving the user's time and effort; and the reset function of the second elastic element 42 can also ensure that the second locking element 41 always remains in the correct position, preventing the second locking element 41 from being misaligned due to external force or misoperation.

[0164] Please refer to Figure 17 and Figure 18 In some embodiments, the second locking member 41 is housed within the second telescopic section 27, the first telescopic section 26 is slidably fitted onto the outer periphery of the second telescopic section 27, a first slot 261 is provided on the first telescopic section 26, a first clearance through hole 271 is provided on the second telescopic section 27, and multiple first slots 261 are provided, and the multiple first slots 261 are spaced apart along the length direction of the second rod 2. Through the above arrangement, the length of the second rod 2 has several positions.

[0165] In other embodiments, the second locking member 41 is housed within the second telescopic section 27, which is slidably fitted onto the outer periphery of the first telescopic section 26. A first slot 261 is provided on the second telescopic section 27, and multiple first clearance holes 271 are provided on the first telescopic section 26, spaced apart along the length of the second rod 2. This arrangement allows the second rod 2 to have several length settings.

[0166] Please refer to Figure 17 and Figure 18 In some embodiments, the first locking structure 3 further includes a linkage 33, which is connected to both the first locking member 31 and the drive assembly 32. The drive assembly 32 drives the first locking member 31 to disengage from the lock hole 11 through the linkage 33.

[0167] Please refer to Figure 17 and Figure 18In some embodiments, the linkage 33 is connected to the second locking member 41, and when the second locking member 41 is at least disengaged from the first slot 261, the linkage 33 is disengaged from the first locking member 31 by the second locking member 41.

[0168] In the above embodiment, when the second locking member 41 is at least disengaged from the first slot 261, the second rod 2 is released and retractable. The linkage 33, driven by the second locking member 41, disengages from the first locking member 31, and the drive assembly 32 can no longer move the first locking member 31, thus keeping the first locking member 31 in the state of being inserted into the lock hole 11. That is, when the user adjusts the length of the second rod 2, the second rod 2 and the first rod 1 will not rotate relative to each other, preventing the cleaning assembly 220 and the body assembly 210 from rotating relative to the second rod 2, thereby reducing the user's operational difficulty and increasing operational stability.

[0169] Please refer to Figure 18 In some embodiments, the first locking structure 3 further includes a third elastic member 34, which is connected to the linkage member 33 and the second telescopic section 27. Under the action of the third elastic member 34, the linkage member 33 is connected to the first locking member 31. When the second locking member 41 is at least disengaged from the first slot 261, the linkage member 33, under the action of the second locking member 41, overcomes the elastic force of the third elastic member 34 and disengages from the first locking member 31.

[0170] Please refer to Figure 18 In some embodiments, the first locking member 31 is provided with a second slot 312, and the linkage member 33 can be inserted into the second slot 312 under the drive of the third elastic member 34.

[0171] In the above embodiment, when the user presses the second trigger 43, the second locking member 41 moves and drives the linkage 33 to overcome the elastic force of the third elastic member 34 and disengage from the second slot 312. When the user stops pressing the second trigger 43, the third elastic member 34 drives the linkage 33 to move and inserts into the second slot 312.

[0172] Please refer to Figure 18 In the initial state, the third elastic member 34 is in a natural or stretched state. The third elastic member 34 provides a pulling force to the linkage member 33 to drive the linkage member 33 closer to the first locking member 31, so that the linkage member 33 is inserted into the second slot 312. When the user presses the second trigger member 43, the second locking member 41 moves and drives the linkage member 33 to stretch the third elastic member 34.

[0173] The above-described embodiment, by setting a third elastic element 34 and utilizing the reset function of the third elastic element 34, can reduce the number of operation steps required by the user, thereby saving the user's time and effort; and the reset function of the third elastic element 34 can also ensure that the linkage 33 always remains in the correct position, preventing the linkage 33 from being misaligned due to external force or misoperation.

[0174] Please refer to Figure 18 It should be noted that when the first locking structure 3 locks the second rod 2 and the first rod 1, the third elastic member 34 can work together with the first elastic member 321 to drive the first locking member 31 to be inserted into the lock hole 11.

[0175] Please refer to Figure 18 In some embodiments, multiple second slots 312 are provided, and the multiple second slots 312 are distributed at intervals along the length direction of the second rod 2.

[0176] It should be noted that since the second locking member 41 can move with the second telescopic section 27, and the linkage member 33 moves with the second locking member 41, the linkage member 33 will also move with the second telescopic section 27 when the second rod 2 retracts. Therefore, as the second rod 2 retracts, the relative position of the linkage member 33 and the second locking member 41 will change. By setting multiple second slots 312, and the multiple second slots 312 are distributed at intervals along the length of the second rod 2, the linkage member 33 can still be engaged in the second slot 312 after it moves with the second telescopic section 27.

[0177] It should be noted that, in Figure 17 and Figure 18 In the embodiment shown, the distance between two adjacent second slots 312 is equal to the distance between two adjacent first slots 261.

[0178] Please refer to Figure 17 and Figure 18 In some embodiments, one of the linkage member 33 and the second locking member 41 is provided with a linkage pin 331, and the other of the linkage member 33 and the second locking member 41 is provided with a linkage groove 411.

[0179] Please refer to Figure 17 and Figure 18 In some embodiments, the linkage pin 331 is slidably disposed within the linkage groove 411 along its length, the length of which is parallel to the direction in which the drive assembly 32 moves the first locking member 31. When the second locking member 41 is at least disengaged from the first slot 261, the inner wall of the linkage groove 411 abuts against the linkage pin 331, thereby causing the linkage member 33 to disengage from the first locking member 31.

[0180] It should be noted that the linkage 33 needs to move with the second locking member 41, and the linkage 33 also needs to drive the first locking member 31 to move independently of the second locking member 41 under the drive of the drive component 32. In the above embodiment, by setting the linkage groove 411 and the linkage pin 331, and the length direction of the linkage groove 411 is parallel to the direction in which the drive component 32 drives the first locking member 31 to move, the linkage 33 can both drive the first locking member 31 to move relative to the second locking member 41 under the drive of the drive component 32, and disengage from the first locking member 31 under the drive of the second locking member 41.

[0181] In the above embodiment, the length of the linkage groove 411 is equal to or greater than the travel distance required for the first locking member 31 to move from the state of being inserted into the lock hole 11 to the state of being disengaged from the lock hole 11.

[0182] Please refer to Figure 17 and Figure 18 In some embodiments, the linkage 33 is rotatably connected to the second telescopic section 27, and the linkage 33 and the second telescopic section 27 can slide along the direction in which the drive assembly 32 drives the first locking member 31 to move.

[0183] With the above configuration, the linkage 33 is rotatably connected to the second telescopic section 27, which limits the position of the linkage 33 to ensure that the linkage 33 always remains in the correct position and prevents the linkage 33 from being misaligned during reciprocating movement. In the above embodiment, under the drive of the second locking member 41, the linkage 33 can rotate relative to the second telescopic section 27 to disengage from the second slot 312; under the drive of the drive assembly 32, the linkage 33 can slide relative to the second telescopic section 27 to drive the first locking member 31 to disengage from the lock hole 11.

[0184] Please refer to Figure 17 and Figure 18 In some embodiments, the first locking structure 3 further includes a first rotating shaft 35 connected to the second telescopic section 27, and the linkage 33 is provided with a connecting hole 332, which is rotatably arranged around the first rotating shaft 35.

[0185] In the above embodiment, the length of the connecting hole 332 is equal to or greater than the travel distance required for the first locking member 31 to move from the state of being inserted into the lock hole 11 to the state of being disengaged from the lock hole 11.

[0186] Please refer to Figure 17 In some embodiments, the second locking structure 4 further includes a second rotating shaft 44 connecting the second telescopic section 27, and the second locking member 41 is rotatably sleeved on the second rotating shaft 44.

[0187] In some embodiments, the first rotating shaft 35 and the second rotating shaft 44 are coaxially arranged.

[0188] Optionally, the first rotating shaft 35 and the second rotating shaft 44 are integrally formed.

[0189] In some embodiments, the handle also includes a second reel 5 for winding up the wire, the second reel 5 being rotatably mounted on the handle.

[0190] With the above setup, the wires inside the second pole 2 are wound on the reel, ensuring that the wires remain taut at different lengths, thus preventing damage to the wiring.

[0191] In some embodiments, a coil spring 51 is provided on the second reel 5. Driven by the coil spring 51, the wire is wound onto the second reel 5. When the second rod 2 extends, it can overcome the elastic force of the coil spring 51 and unwind the wire from the second reel 5.
