Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cleaning, in particular to a handle assembly, a cleaning device and a cleaning system. BACKGROUND

[0002] Cleaning devices such as scrubbers and vacuum cleaners are intelligent products widely used in people's daily life. Taking a scrubber as an example, the scrubber is a cleaning machine suitable for cleaning floors, carpets and other surfaces to be cleaned, which can also suck and remove wastewater from the scene, and has the advantages of environmental protection, energy saving and high efficiency.

[0003] The scrubber includes a handle assembly, a brush assembly and a machine body. The machine body can be used to connect the handle assembly and the brush assembly. The brush assembly is located in front of the handle assembly for cleaning the surface to be cleaned. During the cleaning process of the scrubber, the handle assembly can reach the user's hand for the user to operate. The user can push and pull the handle assembly to control the cleaning direction of the brush assembly.

[0004] In related technologies, the movement mode of the handle assembly is single. The handle assembly can be flipped relative to the machine body, or the handle assembly is telescopic. However, for users of different heights or for cleaning low spaces, the handle assembly is difficult to meet the comfort of use of users, affecting the user experience. Utility model content

[0005] The present application provides a handle assembly, a cleaning device and a cleaning system, which can solve the problem that the movement mode of the handle assembly is single and difficult to meet the use requirements of users of different heights and different application scenarios.

[0006] In a first aspect, the present application provides a handle assembly, comprising:

[0007] a handle body, the handle body being directly or indirectly connected with a machine body of the cleaning device, the handle body being flipable relative to the machine body, the handle body comprising an inner tube and an outer sleeve that slide relative to each other, the outer sleeve being provided with a plurality of gear adjustment holes distributed along the length direction thereof;

[0008] a folding mechanism, the folding mechanism being provided on the handle body, the folding mechanism being provided with a plurality of matching grooves distributed along the length direction thereof;

[0009] a locking piece, the locking piece being matched with the matching grooves to enable the folding mechanism to drive the handle body to be clamped or flipped relative to the machine body;

[0010] A telescopic mechanism is arranged on the handle body, and the telescopic mechanism comprises a locking pin assembly which is inserted into or separated from the gear adjustment hole to lock the outer sleeve and the inner tube or to realize telescopic sliding of the inner tube relative to the outer sleeve.

[0011] The number of the gear adjustment holes is less than or equal to the number of the matching grooves, and the interval between two adjacent gear adjustment holes is equal to the interval between two adjacent matching grooves.

[0012] The handle assembly provided in the present application is provided with a plurality of gear adjustment holes which are distributed at intervals along the length direction of the outer sleeve. The locking pin assembly corresponding to different gear adjustment holes can be used to adjust the relative sliding distance of the inner tube and the outer sleeve, and the handle body can realize telescopic movement, so that the handle body has different lengths at different gears. Since the locking member and the matching groove are matched with each other, the handle body can be driven to be clamped or flipped relative to the body, therefore, by setting the number of the gear adjustment holes to be less than or equal to the number of the matching grooves and the interval between two adjacent gear adjustment holes to be equal to the interval between two adjacent matching grooves, the handle body can be flipped relative to the body at different lengths corresponding to different gears, so that the flipping movement of the handle body relative to the body can be realized, and the telescopic movement of the handle body can also be realized.

[0013] Specifically, taking the example that the number of the gear adjustment holes matches the number of the matching grooves, the gear adjustment holes and the matching grooves can be one-to-one corresponding. When the locking pin assembly is inserted into one of the gear adjustment holes, the length of the handle body can meet the comfort requirement, and the locking member can be located in the matching groove, at this time, the folding mechanism can be used to drive the handle body to be clamped or flipped relative to the body.

[0014] When the locking pin assembly moves to another gear adjustment hole, the locking member can be located in the corresponding matching groove, so that the handle body can be flipped relative to the body when the length of the handle body is fixed.

[0015] According to one embodiment of the present application, when the locking pin assembly is inserted into the gear adjustment hole, the locking member is located in the matching groove.

[0016] In the present application, when the locking pin assembly is inserted into the gear adjustment hole, the inner tube and the outer sleeve are locked, at this time, the locking member is located in the matching groove to drive the handle body to be clamped or flipped relative to the body, therefore, the clamping or flipping movement of the handle body relative to the body and the telescopic movement of the handle body cannot be performed simultaneously. In other words, the clamping or flipping movement of the handle body relative to the body and the telescopic movement of the handle body need to be operated step by step, which is beneficial to improve the reliability of the clamping or flipping movement of the handle body relative to the body and the telescopic movement of the handle body, and can facilitate the user to control the state of the handle body.

[0017] According to one embodiment of this application, the distribution direction of the gear adjustment hole is parallel to the distribution direction of the mating groove.

[0018] In this application, by setting the distribution direction of the gear adjustment holes to be parallel to the distribution direction of the mating grooves, the inner tube can slide relative to the outer tube so that when the locking pin assembly is inserted into different gear adjustment holes, the locking part can be guaranteed to be located in the corresponding mating groove, so as to avoid the locking part from shifting or disengaging from the mating groove, which could affect the possibility of the handle body engaging or flipping relative to the body.

[0019] According to one embodiment of this application, when the inner tube slides telescopically relative to the outer tube, the locking pin assembly slides past at least one of the gear adjustment holes, and the locking member slides past the same number of the mating grooves.

[0020] In this application, during the relative sliding process of the inner tube and the outer tube, the number of gear adjustment holes through which the locking pin assembly passes is equal to the number of mating grooves through which the locking member slides. This ensures that the handle body can achieve the locking or flipping movement relative to the machine body when the handle body is at different lengths, thus preventing the locking member from entering the misaligned mating groove, which could affect the locking or flipping movement of the handle body relative to the machine body, or even affect the telescopic movement of the handle body.

[0021] According to one embodiment of this application, the telescopic mechanism includes a transmission assembly, the transmission assembly being provided with a limiting groove, the transmission assembly moving along the length direction of the outer sleeve to drive the locking member to switch between the mating groove and the limiting groove;

[0022] The transmission component is connected to the locking pin component. The transmission component drives the locking pin component to insert into or disengage from the gear adjustment hole. When the locking pin component disengages from the gear adjustment hole, the locking member is located in the limiting groove.

[0023] In this application, the transmission assembly can be used to drive the locking member to switch between the mating groove and the limiting groove. When the locking member is in the mating groove, the locking pin assembly locks the outer tube and the inner tube to fix the length of the handle body. At this time, the handle body can engage or flip relative to the machine body. When the locking member is in the limiting groove, the locking member disengages from the mating groove, and the handle body cannot engage or flip relative to the machine body. The transmission assembly can also disengage the locking pin assembly from the gear adjustment hole to allow the inner tube to slide telescopically relative to the outer tube.

[0024] Therefore, by setting a locking element that switches between the mating groove and the limiting groove, the synchronous movement of the handle body relative to the machine body in engagement or rotation and the inner tube relative to the outer tube in telescopic sliding can be restricted. In other words, the engagement or rotation of the handle body relative to the machine body and the telescopic sliding of the inner tube relative to the outer tube need to be performed step by step.

[0025] According to one embodiment of this application, the folding mechanism and the telescopic mechanism are arranged side by side along the radial direction of the outer sleeve, and the opening directions of the mating groove and the limiting groove are opposite to each other.

[0026] In this application, the folding mechanism and the telescopic mechanism are arranged side by side along the radial direction of the outer tube, which can effectively utilize the internal space of the inner tube and save the dimensions of the inner tube along its own length. The compact structure of the folding mechanism and the telescopic mechanism is conducive to the miniaturization and weight reduction design of the cleaning equipment.

[0027] By setting the opening directions of the mating groove and the limiting groove to be opposite, the locking component can be easily switched between the two.

[0028] According to one embodiment of this application, the folding mechanism includes a first traction body and a linkage member, the first traction body being slidably connected to the linkage member, the first traction body being provided with the mating groove, and the linkage member being provided with a locking hole;

[0029] When the locking pin assembly is inserted into the gear adjustment hole, the locking member is located in the locking hole and one of the mating grooves, and the first traction body is used to drive the handle body to engage or rotate relative to the body.

[0030] In this application, when the locking member is located in the locking hole and one of the mating grooves, the locking member can lock the first traction body and the linkage member together. The first traction body and the linkage member can move synchronously so that the handle body can be engaged or rotated relative to the machine body through the first traction body. At this time, since the locking pin assembly is inserted into the gear adjustment hole, the outer tube and the inner tube can be locked together, and the length of the handle body cannot be adjusted.

[0031] According to one embodiment of this application, the transmission assembly includes a slider for driving the locking pin assembly, the slider being located within the guide space formed by the linkage and the inner tube, and the slider being provided with the limiting groove;

[0032] When the locking pin assembly disengages from the gear adjustment hole, the locking hole corresponds to the limiting groove, and the locking member is located within the locking hole and the limiting groove.

[0033] In this application, at least some of the linkage components can be located inside the inner tube. The sidewall of the linkage component and the inner wall of the inner tube can form a guide space to allow the slider to slide along the length of the outer tube.

[0034] The slider, sliding along the length of the outer tube, can drive the locking element to switch between the mating groove and the limiting groove. Furthermore, it can also drive the locking pin assembly to lock the outer tube and the inner tube, or enable the inner tube to slide telescopically relative to the outer tube. Therefore, the movement of the slider can synchronously drive the locking pin assembly and the locking element, so that when the locking pin assembly corresponds to the gear adjustment hole, the locking element can be located in the mating groove corresponding to that gear adjustment hole.

[0035] Secondly, this application provides a cleaning device comprising: a body and a handle assembly as described in any of the above embodiments. The handle assembly is connected to the body.

[0036] Thirdly, this application provides a cleaning system including a base or base station. Cleaning equipment can be placed on the base or base station.

[0037] The beneficial effects of the handle assembly provided in this application are as follows: by setting multiple adjustment holes on the outer tube, the length of the handle body can have multiple settings. By setting the number of adjustment holes to be less than or equal to the number of mating slots, and the distance between two adjacent adjustment holes to be equal to the distance between two adjacent mating slots, the handle body can be rotated relative to the main body when the length of the handle body is in different settings, thereby meeting the usage comfort needs of users of different heights and in different application scenarios.

[0038] In addition to the technical problems solved by the embodiments of the present invention, the technical features constituting the technical solutions, and the beneficial effects brought about by the technical features of these technical solutions as described above, other technical problems that can be solved by the handle assembly, cleaning equipment, and cleaning system provided by the embodiments of the present invention, other technical features included in the technical solutions, and the beneficial effects brought about by these technical features will be further explained in detail in the specific embodiments.

[0073] The accompanying drawings have illustrated specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art by referring to specific embodiments. Detailed Implementation

[0074] Exemplary embodiments will be described in detail herein, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims. Clearly, the described embodiments are only a portion, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0075] The cleaning equipment provided in this application can be, but is not limited to, a floor scrubber, an electric broom, an electric mop, or a vacuum cleaner. Taking a floor scrubber as an example, a floor scrubber is a device used to clean floors. The floor can be, but is not limited to, wood flooring, tiles, carpets, etc.

[0076] A floor scrubber typically consists of several parts, including a brush assembly, a roller brush, a clean water tank, and a wastewater tank. The working principle of a floor scrubber is as follows: the high-speed rotation of the motor drives the roller brush to rotate at high speed, while the clean water tank rotates, spraying clean water forward onto the roller brush through a water channel. Combined with the high-speed rotation of the roller brush, wastewater is drawn backward through a vacuum suction channel located behind the roller brush and into the wastewater tank via another water channel, thus completing the cleaning process.

[0077] The floor scrubber includes a handle assembly, a brush assembly, and a body. The body connects the handle assembly and the brush assembly. The brush assembly is located in front of the handle assembly. The brush assembly moves across the surface to be cleaned, cleaning it with a roller brush. During cleaning, the handle assembly is accessible to the user's hand for operation. The user can push or pull the handle assembly to control the cleaning direction of the brush assembly.

[0078] In related technologies, the handle assembly has a limited range of motion. The handle assembly can flip relative to the main body or be retractable. However, for taller users or when cleaning in low-ceilinged spaces, the handle assembly often fails to provide sufficient comfort, negatively impacting the user experience.

[0079] If the structure of the handle assembly flipping relative to the fuselage in related technologies is combined with the structure of the handle assembly being retractable, the flipping motion of the handle assembly relative to the fuselage and the retraction motion of the handle assembly are prone to interference. For example, when the handle assembly is extended to a designated position, it is difficult to achieve the flipping motion of the handle assembly relative to the fuselage, thus affecting the reliability of the flipping and retraction motions.

[0080] Based on the aforementioned technical problems, the applicant has improved the structure of the existing handle assembly. The handle assembly in this application, by providing multiple adjustment holes on the outer sleeve, allows the handle body to have multiple length settings. By setting the number of adjustment holes to be less than or equal to the number of mating slots, and ensuring that the distance between two adjacent adjustment holes is equal to the distance between two adjacent mating slots, the handle body can rotate relative to the main body when its length is at different settings, thereby satisfying the comfort needs of users of different heights and in different application scenarios.

[0081] It should be noted that, in the embodiments of this application, the cleaning equipment can clean low-ceilinged spaces or low-ceilinged usage scenarios. For example, under beds, under sofas, under tables, etc.

[0082] SeeFigures 1 to 4 The following examples illustrate four application scenarios for cleaning equipment, but the application scenarios for cleaning equipment are not limited to these four scenarios.

[0083] Figure 1 An exemplary schematic diagram of the handle assembly 100 and the body in an upright position is shown. When the body is upright, the body and handle assembly 100 are likely to be collinear. In other words, the angle between the body and handle assembly 100 is a straight angle. At this time, the body and the surface to be cleaned can be approximately perpendicular; for example, the angle between the body and the surface to be cleaned can be between 70° and 90°. Users can comfortably hold the handle assembly 100 to clean a spacious surface. An application scenario where the body is in an upright position is where the cleaning device is located on a base or pedestal. For example, the cleaning device can stand vertically on a base or pedestal for cleaning or charging. In this case, the handle assembly 100, the body, and the surface to be cleaned can all remain vertical to save space occupied by the cleaning device.

[0084] Figure 2 An exemplary schematic diagram of the handle assembly 100 extending relative to the body is shown. In this way, the cleaning device can be adapted to users of different heights. By adjusting the different lengths by which the inner tube 112 extends beyond the outer tube 111, the length of the handle assembly 100 is adjusted, thereby adjusting the height of the gripping end of the handle assembly 100 so that users of different heights can comfortably use the cleaning device.

[0085] In some examples, Figure 1 The handle assembly 100 shown can be in its initial state, in which the handle assembly 100 is not flipped relative to the body and can be in an unextended state to facilitate the transportation and storage of the cleaning equipment.

[0086] or, Figure 2 The handle assembly 100 shown can be in its initial state. In this state, the handle assembly 100 is not rotated relative to the machine body, and it is extended a certain distance. For example, the user can adjust the handle assembly 100 according to their height. In the initial state, the handle assembly 100 is already extended a certain distance, so that the user does not need to adjust the length of the handle assembly 100 every time they perform subsequent cleaning work. The user only needs to adjust the handle assembly 100 to rotate relative to the machine body when encountering different low-ceilinged spaces.

[0087] It should be noted that users can set the initial state of the handle component 100 according to their height and application scenario, and this is not limited in the embodiments of this application.

[0088] Figure 3An exemplary schematic diagram of the handle assembly 100 folded relative to the body is shown. In this configuration, the cleaning device can be used to clean surfaces in low-ceilinged spaces. The body and the surface to be cleaned can be brought to a horizontal position, allowing the body to lie flat and facilitating easy access of the brush assembly for cleaning in such spaces.

[0089] It should be noted that when the machine is in a flat position, the machine body and the surface to be cleaned can be roughly parallel. For example, the angle between the machine body and the surface to be cleaned can be between 0° and 10°.

[0090] Figure 4 An exemplary schematic diagram of the handle assembly 100 folding and extending relative to the body is shown. For example, when cleaning a surface to be cleaned in a low-ceilinged space, the handle assembly 100 is folded relative to the body. The height of the gripping end of the handle assembly 100 relative to the surface to be cleaned is reduced, requiring the user to bend over to grip the handle assembly 100. At this time, the handle assembly 100 can be extended to increase the height of the gripping end of the handle assembly 100 relative to the surface to be cleaned, so that the user can clean the surface to be cleaned in a low-ceilinged space without bending over.

[0091] The handle assembly 100, cleaning equipment, and cleaning system provided in this application are described below with reference to the accompanying drawings and specific embodiments.

[0092] See Figures 5 to 11 As shown, the handle assembly 100 of this application embodiment is applied to a cleaning device. The handle assembly 100 may include a handle body 110, a folding mechanism 120, and a locking member 130.

[0093] The handle body 110 is directly or indirectly connected to the body of the cleaning equipment. The handle body 110 can be flipped relative to the body. The handle body 110 includes an outer tube 111 and an inner tube 112. The inner tube 112 is slidably connected to the outer tube 111.

[0094] The folding mechanism 120 is located inside the handle body 110. The folding mechanism 120 includes a folding trigger 121, a traction component, and an unlocking component 123. The folding trigger 121 drives the unlocking component 123 through the traction component to make the handle body 110 flip relative to the body. The traction component has a fixed length mode and a telescopic mode.

[0095] The locking member 130 moves within the handle body 110 to switch between the fixed-length mode and the telescopic mode of the traction component. When the traction component is in the fixed-length mode, the handle body 110 can be rotated relative to the machine body. When the traction component is in the telescopic mode, the inner tube 112 can slide relative to the outer tube 111 to extend or retract the handle body 110.

[0096] It should be noted that the fixed-length mode of the traction assembly refers to the synchronous movement between the internal structures of the traction assembly, allowing its overall length to remain constant during movement. The telescopic mode of the traction assembly refers to the relative movement between the internal structures of the traction assembly, causing its overall length to change. The overall length of the traction assembly can extend or shorten.

[0097] In this embodiment, by setting the locking member 130, the traction component can have a fixed length mode and a telescopic mode, which can realize the flipping of the handle body 110 relative to the machine body, and can also realize the length adjustment of the handle body 110, which can meet the comfort of users of different heights and different application scenarios.

[0098] When the traction component is in fixed length mode, the handle body 110 can be flipped relative to the body, so that the body can lie flat and the floor brush component can reach into low spaces to clean them.

[0099] When the traction component is in telescopic mode, the inner tube 112 of the handle body 110 can slide relative to the outer tube 111. By adjusting the length of the inner tube 112 extending relative to the outer tube 111, the length of the handle assembly 100 can be adjusted to meet the usage needs of users of different heights and in different application scenarios. For example, when the device is in an upright position, for shorter users, the length of the inner tube 112 extending from the outer tube 111 can be adjusted to be smaller, or the inner tube 112 can be adjusted not to extend from the outer tube 111. For taller users, the length of the inner tube 112 extending from the outer tube 111 can be adjusted to be larger, thereby increasing the overall length of the handle assembly 100, increasing the height of the grip end of the handle assembly 100, and improving the user comfort of taller users.

[0100] Furthermore, when the machine is in a flat position, the height of the gripping end of the handle assembly 100 is reduced. Especially for taller users, the inner tube 112 can be adjusted to extend beyond the outer tube 111, increasing the height of the gripping end of the handle assembly 100. This allows users to operate the handle assembly 100 without bending over or squatting, improving the comfort of using the cleaning equipment when cleaning low spaces.

[0101] In some examples, the handle body 110 is directly or indirectly connected to the body of the cleaning equipment. Specifically, the handle body 110 can be directly rotatably connected to the body, or the handle body 110 can be connected to the body via an adapter rod 160. This is not limited in the embodiments described in this application.

[0102] For example, refer to Figures 1 to 4As shown, when the handle body 110 is connected to the machine body via the adapter rod 160, the handle body 110 and the adapter rod 160 can be rotatably connected via the rotating shaft 180. The adapter rod 160 and the machine body can be fixedly connected by, but is not limited to, a snap-fit ​​method.

[0103] In some examples, the grip end of the handle assembly 100 may be equipped with operation buttons. These operation buttons can be physical buttons or touch buttons, and are not limited in this embodiment. The floor brush assembly may include a control module to control the cleaning mode of the cleaning equipment. The operation buttons and the control module can be electrically connected via a conductive cable 190, so that when the user triggers the operation button, the floor brush assembly can be controlled to operate in different cleaning modes.

[0104] The handle assembly 100 includes a space for accommodating the conductive cable 190. The end of the handle assembly 100 for connection to the main body may have a terminal block. The terminal block is electrically connected to the conductive cable 190. The terminal block can be plugged into the main body to electrically connect the conductive cable 190 to the control module.

[0105] In some examples, when the cleaning device moves across a horizontal surface to be cleaned, the handle body 110 can be tilted in a vertical plane relative to the body. The axis of rotation 180 is perpendicular to the vertical plane.

[0106] In some examples, the outer tube 111 may be fitted over at least a portion of the inner tube 112. Since the inner tube 112 is slidably connected to the outer tube 111, the greater the extension of the inner tube 112 beyond the outer tube 111, the greater the overall length of the handle body 110. The axial direction of the inner tube 112 and the outer tube 111 may be the same. The sliding direction of the inner tube 112 and the outer tube 111 may be the same as the axial direction of the inner tube 112.

[0107] In some examples, the external force applied to the folding trigger 121 can come from the hand holding the handle body 110. In other words, an external force can be applied to the folding trigger 121 while holding the handle body 110 with one hand, thus enabling the handle body 110 to be flipped relative to the main body with one hand, allowing the main body to switch between a flat and upright position. This process eliminates the need for two hands, making operation quick and convenient, and improving the user experience.

[0108] In some examples, the outer tube 111 and the inner tube 112 may be, but are not limited to, round tubes, square tubes, etc.

[0109] This application provides another handle assembly 100. The handle assembly 100 may include a handle body 110, a folding mechanism 120, and a locking member 130.

[0110] The handle body 110 is directly or indirectly connected to the body of the cleaning equipment. The handle body 110 can be flipped relative to the body. The handle body 110 includes an outer tube 111 and an inner tube 112, the inner tube 112 being slidably connected to the outer tube 111.

[0111] The folding mechanism 120 is located within the handle body 110. The folding mechanism 120 may include a folding trigger 121, a traction assembly, and an unlocking member 123. The folding trigger 121 drives the unlocking member 123 through the traction assembly to flip the handle body 110 relative to the main body; the traction assembly has a fixed-length mode and a telescopic mode.

[0112] The locking member 130 moves within the handle body 110 to have a locked position and a disengaged position. When the locking member 130 is in the locked position, the traction assembly is in a fixed-length mode, and the handle body 110 can be flipped relative to the machine body. When the locking member 130 is in the disengaged position, the traction assembly is in a telescopic mode, and the inner tube 112 can slide relative to the outer tube 111 to achieve telescopic extension of the handle body 110.

[0113] In this embodiment, the locking member 130 is used to switch the traction assembly between a fixed-length mode and a telescopic mode. By switching the locking member 130 between the locked position and the disengaged position, the traction assembly can be switched between the fixed-length mode and the telescopic mode.

[0114] Specifically, when the locking member 130 is in the locked position, it can lock the internal structure of the traction assembly, keeping the overall length of the traction assembly fixed, and the traction assembly is in a fixed-length mode. At least a portion of the traction assembly can be used to drive the unlocking member 123 to move, so that the handle body 110 can be rotated relative to the machine body. When the locking member 130 is in the disengaged position, the locking between the internal structures of the traction assembly can be released, and there can be relative movement between the internal structures of the traction assembly, so that the overall length of the traction assembly can be extended or retracted. Thus, by extending or retracting the traction assembly, the inner tube 112 can slide relative to the outer tube 111, thereby adjusting the length of the handle body 110.

[0115] It should be noted that, since the traction component is in a fixed-length mode when the locking member 130 is in the locked position, it is difficult to achieve sliding of the inner tube 112 relative to the outer tube 111. Similarly, since the traction component is in a telescopic mode when the locking member 130 is in the disengaged position, it is difficult to achieve flipping of the handle body 110 relative to the main body.

[0116] Therefore, by providing a locking position and a disengaged position for the locking element 130, the rotational movement of the handle body 110 relative to the machine body and the sliding movement of the inner tube 112 of the handle body 110 relative to the outer tube 111 can be independent of each other. During the rotation of the handle body 110 relative to the machine body, the inner tube 112 and the outer tube 111 can be relatively fixed, and the length of the handle body 110 cannot be adjusted. After the rotation angle of the handle body 110 relative to the machine body is adjusted, the relative sliding of the inner tube 112 and the outer tube 111 can be adjusted to adjust the length of the handle body 110.

[0117] Similarly, during the relative sliding of the inner tube 112 and the outer tube 111, the angle of rotation of the handle body 110 relative to the machine body can remain fixed and cannot be adjusted. After the relative sliding distance between the inner tube 112 and the outer tube 111 is adjusted, the angle of rotation of the handle body 110 relative to the machine body can be adjusted.

[0118] This design facilitates user control of the handle body 110, avoiding the possibility of complicated operation of the handle body 110 due to simultaneous flipping and extension movements.

[0119] See also some of the possible implementation methods. Figure 8 and Figure 9 As shown, the traction assembly of this application embodiment may include a first traction body 1221 and a linkage member 1222. The first traction body 1221 is connected to the unlocking member 123, and the linkage member 1222 is connected to the folding trigger member 121.

[0120] Locking member 130 locks the first traction body 1221 and linkage member 1222, so that the first traction body 1221 and linkage member 1222 move synchronously, and the traction assembly is in a fixed-length mode. Locking member 130 unlocks the first traction body 1221 and linkage member 1222, so that the first traction body 1221 slides relative to linkage member 1222. The traction assembly is in a telescopic mode.

[0121] In this embodiment, the first traction body 1221 and the linkage 1222 have two motion states, corresponding to the fixed-length mode and the telescopic mode of the traction assembly, respectively. Specifically, when the locking member 130 is in the locked position, the first traction body 1221 and the linkage 1222 are locked together by the locking member 130. The first traction body 1221 and the linkage 1222 can move synchronously, ensuring that the overall length of the traction assembly remains fixed during movement. In other words, the traction assembly is in the fixed-length mode. Therefore, the first traction body 1221 and the linkage 1222 can work together to drive the unlocking member 123 to rotate the handle body 110 relative to the main body.

[0122] When the locking element 130 is in the disengaged position, it can unlock the first traction body 1221 and the linkage element 1222. The first traction body 1221 and the linkage element 1222 can slide relative to each other. One of the first traction body 1221 and the linkage element 1222 can be used to allow the inner tube 112 to slide relative to the outer tube 111. Since the first traction body 1221 is connected to the unlocking element 123, the movement of the first traction body 1221 will cause the unlocking element 123 to move, affecting the relative position of the handle body 110 and the body. Therefore, the movement of the linkage element 1222 can allow the inner tube 112 and the outer tube 111 to slide relative to each other. In other words, the first traction body 1221 can remain stationary relative to the handle body 110, and the linkage element 1222 can slide relative to the first traction body 1221 to allow the inner tube 112 and the outer tube 111 to slide relative to each other.

[0123] In some examples, the linkage 1222 may be fitted over at least a portion of the first traction body 1221. One end of the first traction body 1221 may extend beyond the linkage 1222 to drive the unlocking member 123 to move.

[0124] In some examples, the relative sliding direction of the first traction body 1221 and the linkage 1222 can be along the axial direction of the inner tube 112. In other words, the relative sliding direction of the first traction body 1221 and the linkage 1222 is the same as the relative sliding direction of the inner tube 112 and the outer tube 111, so that the movement of the linkage 1222 can directly act on the inner tube 112, reducing the complexity of the internal structure of the handle assembly 100.

[0125] See also some of the possible implementation methods. Figure 8 and Figure 9 As shown, at least a portion of the first traction body 1221 in this embodiment is located inside the linkage member 1222. The first traction body 1221 is provided with a mating groove 1221a that can accommodate at least a portion of the locking member 130. The linkage member 1222 is provided with a locking hole 122a through which the locking member 130 can pass.

[0126] When the traction assembly is in fixed-length mode, the mating groove 1221a and the locking hole 122a can correspond to each other. The locking member 130 is located within the mating groove 1221a and the locking hole 122a. When the traction assembly is in telescopic mode, the mating groove 1221a and the locking hole 122a can be staggered. The locking member 130 is separated from the first traction body 1221.

[0127] In this embodiment, the locking member 130 can be switched between a locked position and a disengaged position by cooperating with the mating groove 1221a and the locking hole 122a. This configuration allows for the switching of the traction assembly between a fixed-length mode and a telescopic mode using a simple structure.

[0128] Specifically, the locking member 130 can move within the inner tube 112. When the mating groove 1221a and the locking hole 122a correspond, at least a portion of the locking member 130 can be located within the mating groove 1221a and the locking groove. The locking member 130 can lock the first traction body 1221 and the linkage member 1222 to restrict relative sliding between the first traction body 1221 and the linkage member 1222, thereby allowing the first traction body 1221 and the linkage member 1222 to move synchronously. The overall length of the traction assembly remains fixed, and the traction assembly is in a fixed-length mode. At this time, the unlocking member 123 can be driven to move by the first traction body 1221 to cause the handle body 110 to rotate relative to the body.

[0129] When the mating groove 1221a and the locking hole 122a are offset along the direction of movement of the first traction body 1221 relative to the linkage member 1222, the locking member 130 can disengage from the mating groove 1221a. In other words, the locking member 130 does not contact the first traction body 1221. At this time, part of the locking member 130 can be located in the locking hole 122a of the linkage member 1222, and the locking member 130 contacts the linkage member 1222. The locking member 130 and the linkage member 1222 can move synchronously so that the linkage member 1222 can slide relative to the first traction body 1221.

[0130] In some examples, the relative movement direction between the first traction body 1221 and the linkage 1222 is the axis of the inner tube 112. When the locking member 130 disengages from the mating groove 1221a to the disengaged position, the traction assembly is in telescopic mode. Figure 8 and Figure 9 As shown, when the linkage 1222 moves to the right (away from the body), the overall length of the traction component can increase, thereby increasing the overall length of the handle body 110. After the overall length of the handle body 110 increases, when it is necessary to reduce the length of the handle body 110, the linkage 1222 can be moved to the left (closer to the body) to reduce the overall length of the traction component, thus meeting the usage comfort needs of users of different heights and in different application scenarios.

[0131] It should be noted that since the locking member 130 is disengaged from the mating groove 1221a of the first traction body 1221, the first traction body 1221 can remain stationary when the linkage member 1222 moves, thus not affecting the movement state of the unlocking member 123, and consequently the handle body 110 will not flip relative to the body.

[0132] In some examples, the surfaces of the locking member 130 that mate with the mating groove 1221a can be curved to improve the smoothness of switching between the locked and disengaged positions of the locking member 130. Furthermore, this can reduce the force required to drive the locking member 130, thus reducing the likelihood of requiring a large driving force during its movement and thus reducing the effort required.

[0133] In some examples, when the locking member 130 is in the locked position, the cross-sectional shape of the locking member 130 may be the same as the cross-sectional shape of the mating groove 1221a. The cross-section may refer to... Figure 8 The horizontal plane in the indicated direction.

[0134] For example, the locking member 130 can be a cylindrical structure. The mating groove 1221a can be a semi-cylindrical groove structure. Here, the semi-cylindrical groove structure refers to an incomplete cylindrical structure.

[0135] See also some of the possible implementation methods. Figures 8 to 11 As shown, the handle assembly 100 of this embodiment may further include a telescopic mechanism 140. At least a portion of the telescopic mechanism 140 moves within the inner tube 112. The telescopic mechanism 140 may be provided with a limiting groove 140a that can accommodate at least a portion of the locking member 130. When the traction assembly is in the telescopic mode, the limiting groove 140a corresponds to the mating groove 1221a, the locking member 130 is located in the limiting groove 140a and the locking hole 122a, and the locking member 130 is disengaged from the mating groove 1221a.

[0136] In this embodiment of the application, by providing a limiting groove 140a on the telescopic mechanism 140 that can accommodate at least part of the locking member 130, the limiting groove 140a can provide space for the locking member 130 to disengage from the mating groove 1221a, so as to realize the switching of the locking member 130 from the locked position to the disengaged position.

[0137] The telescopic mechanism 140 can move within the inner tube 112. When the limiting groove 140a on the telescopic mechanism 140 corresponds to the locking hole 122a on the linkage member 1222, the locking member 130 can disengage from the mating groove 1221a and fall into the mating groove 1221a through the locking hole 122a on the linkage member 1222. At this time, the linkage member 1222 can move relative to the first traction body 1221, so that the traction assembly is in the telescopic mode.

[0138] When the traction assembly is in telescopic mode, the locking member 130 can be located within the locking hole 122a and the limiting groove 140a, so that the linkage member 1222 and the telescopic mechanism 140 can operate synchronously. The linkage member 1222 moves axially along the inner tube 112 to adjust the distance the inner tube 112 extends relative to the outer tube 111, thereby adjusting the overall length of the handle body 110.

[0139] Therefore, the linkage 1222 enables the coordinated movement of the folding mechanism 120 and the telescopic mechanism 140, and the folding mechanism 120 and the telescopic mechanism 140 do not interfere with each other. When the locking member 130 is in the locked position, the traction component is in a fixed-length mode, and the linkage 1222, together with the first traction body 1221, drives the unlocking member 123 to rotate the handle body 110 relative to the main body. When the locking member 130 is in the disengaged position, the traction component is in a telescopic mode, and the linkage 1222 can move relative to the first traction body 1221. The linkage 1222 can also move synchronously with the telescopic mechanism 140 to adjust the overall length of the handle body 110.

[0140] In some examples, the surface of the limiting groove 140a that mates with the locking member 130 may be curved to improve the smoothness of switching between the locked and disengaged positions of the locking member 130. Exemplarily, the locking member 130 may be a cylindrical structure. The limiting groove 140a may be a semi-cylindrical groove structure.

[0141] In some examples, the shape of the locking hole 122a can match the shape of the locking member 130. During the switching between the locked and disengaged positions, the locking member 130 can remain within the locking hole 122a.

[0142] In some examples, the linkage 1222 may be, but is not limited to, a sleeve structure. For example, the linkage 1222 may be a square sleeve. Since the linkage 1222 is sleeved on the outside of at least a portion of the first traction body 1221, the first traction body 1221 may be a square rod structure.

[0143] See also some of the possible implementation methods. Figure 8 As shown, the locking hole 122a of this embodiment can be provided on the side wall of the linkage 1222 near the telescopic mechanism 140. When the traction assembly is in the fixed length mode, the side wall is aligned with the center of the locking member 130 along the extension direction of the side wall.

[0144] In this embodiment of the application, during the process of switching the locking member 130 from the locked position to the disengaged position, when the telescopic mechanism 140 moves to make the limiting groove 140a correspond to the locking hole 122a and the mating groove 1221a, by setting the side wall of the linkage member 1222 and the center of the locking member 130 to be aligned in the extension direction of the side wall, the switching of the locking member 130 from the locked position to the disengaged position can be facilitated.

[0145] Specifically, refer to Figures 8 to 11 As shown, when the telescopic mechanism 140 moves to the position where the limiting groove 140a corresponds to the locking hole 122a and the mating groove 1221a, on the one hand, the locking member 130 can fall downward into the limiting groove 140a under its own weight. The locking member 130 can disengage from the mating groove 1221a of the first traction body 1221, thereby allowing the traction assembly to switch to telescopic mode. On the other hand, when the locking member 130 is not completely disengaged from the mating groove 1221a of the first traction body 1221, the linkage 1222 can apply a rightward force to the locking member 130, which passes through the center of the locking member 130. At the same time, the limiting groove 140a and the mating surface near the right side can apply a leftward force to the locking member 130, and the limiting groove 140a applies an eccentric force to the locking member 130. Therefore, under the action of the mating surface of the mating groove 1221a of the linkage 1222 and the first traction body 1221, the locking member 130 can be driven to switch from the mating groove 1221a to the limiting groove 140a, so that the locking member 130 switches from the locked position to the disengaged position, thereby the traction assembly switches from the fixed length mode to the telescopic mode.

[0146] In some examples, the mating groove 1221a may have a guiding mating surface. The mating surface on the mating groove 1221a may be a rounded or chamfered structure.

[0147] In some examples, the first traction body 1221 and the telescopic mechanism 140 can be arranged side by side in the inner tube 112. Furthermore, the telescopic mechanism 140 can be located on the side of the first traction body 1221 closer to the surface to be cleaned, for example... Figure 11 The telescopic mechanism 140 is located below the first traction body 1221 so that when the locking member 130 switches from the locked position to the disengaged position, the locking member 130 can fall into the limiting groove 140a under its own gravity.

[0148] When the locking element 130 switches from the disengaged position to the locked position, refer to Figures 8 to 11In the indicated direction, the limiting groove 140a of the telescopic mechanism 140 first aligns with the limiting groove 140a of the first traction body 1221, and then the telescopic mechanism 140 can reset to the right. At this time, the telescopic mechanism 140 can apply a rightward force to the locking member 130. The mating surface of the limiting groove 140a and the left side of the locking member 130 can apply an upward inclined force to the locking member 130, so as to squeeze the locking member 130 out of the limiting groove 140a into the mating groove 1221a, so that the locking member 130 switches from the disengaged position to the locked position, thereby switching the traction assembly from the telescopic mode to the fixed length mode.

[0149] In some examples, the limiting groove 140a may have a guiding mating surface. The mating surface on the limiting groove 140a may be a rounded or chamfered structure.

[0150] In some examples, the mating groove 1221a may be provided on the surface of the first traction body 1221 facing the telescopic mechanism 140. The locking hole 122a may be provided on the inner wall of the linkage 1222 near the mating groove 1221a. The limiting groove 140a may be provided on the surface of the telescopic mechanism 140 facing the folding mechanism 120.

[0151] See also some of the possible implementation methods. Figure 8 and Figure 9 As shown, in this embodiment of the invention, one end of the unlocking member 123 is rotatably connected to the handle body 110, and the other end of the unlocking member 123 is rotatably connected to the first traction body 1221. When the traction assembly is in the fixed-length mode, the unlocking member 123 moves to unlock directly or indirectly with the machine body, and the handle body 110 can be flipped relative to the machine body.

[0152] It should be noted that when the handle body 110 is connected to the body via the adapter rod 160, since the body is fixedly connected to the adapter rod 160, the indirect unlocking of the unlocking component 123 and the body means that the unlocking component 123 unlocks the body by unlocking the adapter rod 160.

[0153] In this embodiment, taking the connection between the handle body 110 and the main body via the adapter rod 160 as an example, when cleaning a spacious surface, the unlocking member 123 and the adapter rod 160 can be engaged, allowing the main body to stand upright. When cleaning a low-ceilinged space, the locking member 130 is moved to put the traction component into a fixed-length mode. At this time, the first traction body 1221 can drive the unlocking member 123 to move, allowing the unlocking member 123 to unlock from the adapter rod 160. The handle body 110 can then be flipped relative to the adapter rod 160, thereby adjusting the main body to a flat position for cleaning low-ceilinged spaces.

[0154] In some examples, the adapter rod 160 may be detachably attached to the body. The handle assembly 100 may be detachable from the body via the adapter rod 160 to facilitate the transport or storage of the cleaning equipment.

[0155] In some feasible implementations, when the handle body 110 is connected to the body via the adapter rod 160, the adapter rod 160 may be provided with a locking groove. When part of the unlocking member 123 is located in the locking groove, the locking groove can restrict the movement of the unlocking member 123, so that the handle body 110 and the adapter rod 160 are relatively fixed. The handle body 110 cannot be rotated relative to the body.

[0156] Specifically, refer to Figure 9 In the indicated direction, with the traction assembly in a fixed-length mode, the first traction body 1221 drives the unlocking member 123 to rotate clockwise, causing the unlocking member 123 to disengage from the limiting groove 160a. The unlocking member 123 can be completely located outside the locking groove, so that the unlocking member 123 is no longer limited by the locking groove, thereby allowing the handle body 110 to flip relative to the adapter rod 160.

[0157] In some feasible implementations, the folding mechanism 120 of this application embodiment may further include an unlocking elastic element. One end of the unlocking elastic element is connected to the handle body 110, and the other end is connected to the unlocking member 123. The folding trigger 121 is used to directly or indirectly unlock the unlocking member 123 from the body, allowing the handle body 110 to flip relative to the body. The unlocking elastic element is used to directly or indirectly lock the unlocking member 123 to the body.

[0158] Specifically, the direct unlocking or locking of the unlocking component 123 to the body means that when the handle body 110 is directly connected to the body, the unlocking component 123 can be directly unlocked or locked to the body. The indirect unlocking or locking of the unlocking component 123 to the body means that the handle body 110 is connected to the body via an adapter rod 160. The unlocking component 123 achieves unlocking or locking with the body through unlocking or locking with the adapter rod 160.

[0159] In this embodiment, the unlocking elastic element can be used to drive the unlocking member 123 back into the limiting groove 160a. In other words, through the unlocking elastic element, the unlocking member 123 can switch from a state detached from the limiting groove 160a to a state located within the limiting groove 160a.

[0160] Specifically, when the traction assembly is in a fixed-length mode, the first traction body 1221 drives the unlocking member 123 to rotate clockwise so that the unlocking member 123 disengages from the limiting groove 160a. During this process, the unlocking elastic member can undergo elastic deformation. In other words, when the first traction body 1221 drives the unlocking member 123 to rotate, it needs to overcome the elastic force of the unlocking elastic member. Therefore, when the first traction body 1221 releases the force on the unlocking member 123, the unlocking elastic member can release elastic potential energy to drive the unlocking elastic member back into the limiting groove 160a, thereby locking the unlocking member 123 with the limiting groove 160a, and preventing the handle body 110 from rotating relative to the main body.

[0161] It should be noted that during the rotation of the handle body 110 relative to the main body, under the elastic action of the unlocking elastic element, the part of the unlocking member 123 that engages with the limiting groove 160a can abut against the outer wall of the adapter rod 160. The unlocking elastic element can always apply a force to the unlocking member 123 to return it to the limiting groove 160a.

[0162] In some examples, the unlocking elastic element can be, but is not limited to, a torsion spring.

[0163] In some possible implementations, the folding trigger 121 slides relative to the handle body 110 to trigger the unlocking element 123 to unlock directly or indirectly from the body, and the handle body 110 can be flipped relative to the body.

[0164] The folding mechanism 120 may also include a trigger reset member 124. One end of the trigger reset member 124 is connected to the handle body 110. The other end of the trigger reset member 124 is connected to the folding trigger member 121. The trigger reset member 124 is used to drive the folding trigger member 121 to reset, and the unlocking member 123 can be directly or indirectly locked to the body.

[0165] In this embodiment, the user can operate the folding trigger 121 to disengage the unlocking member 123 from the limiting groove 160a, thereby enabling the handle body 110 to flip relative to the main body. The main body can then be switched to a flat position for cleaning low-lying spaces. During the process of the unlocking member 123 disengaging from the limiting groove 160a, the trigger reset member 124 can deform. In other words, when the folding trigger 121 is triggered, the force exerted by the trigger reset member 124 must be overcome.

[0166] After cleaning low-ceilinged spaces, the unlocking elastic element and the trigger reset element 124 can work together to switch the machine body from a lying position to an upright position or other positions. At this time, the handle body 110 can be adjusted to rotate relative to the machine body so that the unlocking element 123 corresponds to the limiting groove 160a. Then, the unlocking elastic element can drive the unlocking element 123 to reset into the limiting groove 160a. The unlocking elastic element can also drive the traction component to reset. Furthermore, the trigger reset element 124 can release the deformation force to drive the unlocking element 123 back into the limiting groove 160a.

[0167] In some examples, the direction of movement of the folding trigger 121 is the same as the direction of relative movement of the first traction body 1221 and the linkage 1222.

[0168] See also some of the possible implementation methods. Figure 8 and Figure 9 As shown, the folding mechanism 120 may further include a second traction body 1223. One end of the second traction body 1223 is rotatably connected to the first traction body 1221, and the other end of the second traction body 1223 is rotatably connected to the unlocking member 123.

[0169] In this embodiment of the application, by setting the two ends of the second traction body 1223 to be rotatably connected to the first traction body 1221 and the unlocking member 123 respectively, the rotation drive of the first traction body 1221 on the unlocking member 123 can be realized.

[0170] In this embodiment, the first traction body 1221 can be a rigid structure to accommodate the relative sliding between the inner tube 112 and the outer tube 111, and it has high motion reliability. By setting the second traction body 1223 to a flexible structure, the force of the first traction body 1221 moving axially along the inner tube 112 can be converted into a force driving the unlocking member 123 to rotate. The structure of the first traction body 1221 and the second traction body 1223 moving in coordination has the advantages of stability, reliability, simple structure, and small size.

[0171] For example, the first traction body 1221 can be a rod structure. The second traction body 1223 can be, but is not limited to, a rope.

[0172] See also some of the possible implementation methods. Figures 8 to 11 As shown, the telescopic mechanism 140 may further include a transmission assembly 141 and a locking pin assembly 142. A limiting groove 140a is provided in the transmission assembly 141. The locking pin assembly 142 is connected to the transmission assembly 141. The transmission assembly 141 drives the locking pin assembly 142 to move, thereby locking or unlocking the length of the inner tube 112 extending out of the outer tube 111.

[0173] When at least a portion of the locking member 130 is located in the mating groove 1221a, the traction assembly is in a fixed-length mode. The locking pin assembly 142 can lock the length of the inner tube 112 extending out of the outer tube 111. When at least a portion of the locking member 130 is located in the limiting groove 140a, the traction assembly is in a telescopic mode, and the locking pin assembly 142 can unlock the length of the inner tube 112 extending out of the outer tube 111.

[0174] In this embodiment, since the limiting groove 140a is located on the transmission assembly 141, the movement of the transmission assembly 141 allows the locking member 130 to switch between the locked and disengaged positions. When the locking member 130 is located in the mating groove 1221a, the traction assembly is in a fixed-length mode, and the locking member 130 can drive the unlocking member 123 to move so that the handle body 110 can be rotated relative to the machine body. At this time, the locking pin assembly 142 can be locked between the inner tube 112 and the outer tube 111 to prevent relative sliding between the inner tube 112 and the outer tube 111. The length of the handle body 110 is not adjustable. When the locking member 130 is located in the limiting groove 140a, the traction assembly is in a telescopic mode, and the locking member 130 can lock the transmission assembly 141 and the linkage member 1222. The transmission assembly 141 and the linkage member 1222 can move synchronously. At this time, the handle body 110 cannot be rotated relative to the machine body. The movement of the transmission component 141 can unlock the locking pin component 142, which limits the inner tube 112 and the outer tube 111. The movement of the linkage component 1222 can cause the inner tube 112 and the outer tube 111 to move relative to each other, thereby adjusting the length of the handle body 110.

[0175] It is easy to understand that when the locking member 130 is in the locked position, the locking pin assembly 142 can lock the inner tube 112 and the outer tube 111, and there will be no relative sliding between the inner tube 112 and the outer tube 111. When the locking member 130 is in the disengaged position, the locking pin assembly 142 can unlock the inner tube 112 and the outer tube 111, and the length of the inner tube 112 extending relative to the outer tube 111 is adjustable.

[0176] In some examples, the inner tube 112 may be provided with a clearance hole 112a. The outer tube 111 may be provided with multiple gear adjustment holes 111a. When the locking pin assembly 142 corresponds to the clearance hole 112a and the gear adjustment hole 111a, the locking pin assembly 142 can be inserted into the clearance hole 112a and the gear adjustment hole 111a, so that the inner tube 112 and the outer tube 111 are locked together. There will be no relative sliding between the inner tube 112 and the outer tube 111. When the locking pin assembly 142 does not correspond to the gear adjustment hole 111a, the locking pin assembly 142 will not hinder the movement of the inner tube 112 relative to the outer tube 111. The locking pin assembly 142 can move within the inner tube 112 so that when the length of the inner tube 112 extending out of the outer tube 111 is sufficient for comfortable use, the locking pin assembly 142 can be inserted into the corresponding gear adjustment hole 111a.

[0177] In some possible implementations, the telescopic mechanism 140 may also include a telescopic trigger 143. The telescopic trigger 143 may be located at the end of the handle body 110 away from the main body. The telescopic trigger 143 is connected to the transmission assembly 141. The telescopic trigger 143 is used to trigger the transmission assembly 141 to drive the locking pin assembly 142 to lock or unlock the inner tube 112 by the length extending from the outer tube 111.

[0178] In this embodiment of the application, when it is necessary to adjust the length of the handle body 110, the telescopic mechanism 140 can be driven to move by the telescopic trigger 143 so that the locking member 130 is switched to the disengaged position and the traction component can be in the telescopic mode. Thus, through the synchronous movement of the linkage member 1222 and the transmission component 141, the locking pin component 142 adjusts the length of the inner tube 112 extending out of the outer tube 111.

[0179] This application also provides a cleaning device, which may include a main body and a handle assembly 100 as described in any of the above embodiments. The handle assembly 100 is connected to the main body.

[0180] In some examples, the cleaning equipment may also include a clean water tank and a wastewater tank. The clean water tank and wastewater tank may be mounted on the floor brush assembly or on the main body. Alternatively, one of the clean water tank and wastewater tank may be mounted on the floor brush assembly, and the other may be mounted on the main body. This application does not impose any limitations on the embodiments described.

[0181] This application also provides a cleaning system. The cleaning system may include a base or a base station. The cleaning equipment may be placed on the base or base station.

[0182] In some examples, the base can be used to clean and dry the roller brush to prevent it from being damp for extended periods, which could lead to odors or bacteria.

[0183] In some examples, the base station may have a charging function. When the cleaning equipment is placed on the base station, it can charge the base station and automatically supply and drain water. The base and the base station can be separate structures, or they can be an integrated structure; this is not limited in the embodiments of this application.

[0184] See Figures 8 to 11 As shown, the handle assembly 100 of this application embodiment is applied to a cleaning device. The handle assembly 100 may include a handle body 110, a locking member 130, a folding mechanism 120, and a telescopic mechanism 140.

[0185] The handle body 110 is directly or indirectly connected to the body of the cleaning equipment. The handle body 110 can be flipped relative to the body. The handle body 110 includes an outer tube 111 and an inner tube 112. The inner tube 112 is slidably connected to the outer tube 111. The locking member 130 can move within the handle body 110.

[0186] A folding mechanism 120 is provided on the handle body 110. The folding mechanism 120 has a mating groove 1221a that can accommodate at least part of the locking member 130. The folding mechanism 120 is used to engage or flip the handle body 110 relative to the body when the locking member 130 is located in the mating groove 1221a.

[0187] The telescopic mechanism 140 includes a transmission assembly 141 and a locking pin assembly 142. The transmission assembly 141 is connected to the locking pin assembly 142. The transmission assembly 141 drives the locking pin assembly 142 to lock or unlock the inner tube 112 and the outer tube 111. The transmission assembly 141 is provided with a limiting groove 140a that can accommodate at least part of the locking member 130. The transmission assembly 141 moves along the length of the outer tube 111 to drive the locking member 130 to switch between the mating groove 1221a and the limiting groove 140a.

[0188] When the locking member 130 enters the limiting groove 140a, the inner tube 112 and the outer tube 111 are unlocked by the locking pin assembly 142, so that the inner tube 112 can slide telescopically relative to the outer tube 111.

[0189] It should be noted that the embodiments described in this application take the connection between the handle body 110 and the body of the cleaning equipment via the adapter rod 160 as an example.

[0190] In this embodiment, the folding mechanism 120 and the telescopic mechanism 140 can be used to flip the handle body 110 relative to the main body, and also to extend or retract the handle body 110. Therefore, the handle body 110 can flip relative to the main body, allowing the main body to lie flat for cleaning in low-ceilinged spaces. Furthermore, the handle body 110 can extend or retract to accommodate users of different heights. Additionally, the length of the handle body 110 can be adjusted by extending or retracting it after it has flipped relative to the main body. Alternatively, the length of the handle body 110 can be adjusted by extending or retracting it before flipping it relative to the main body. Therefore, the handle assembly 100 of this embodiment can meet the comfort needs of users of different heights and in different application scenarios.

[0191] Specifically, the folding mechanism 120 allows the handle body 110 to engage or flip relative to the main body. When the handle body 110 is engaged with the main body, there is no flipping motion between them. When the handle body 110 can flip relative to the main body, the main body can be placed in a flat position for cleaning low-ceilinged spaces.

[0192] The extension and retraction of the handle body 110 can be achieved through the telescopic mechanism 140. Specifically, when relative sliding occurs between the inner tube 112 and the outer tube 111, the extension and retraction of the handle body 110 can be achieved through this relative sliding, thus adjusting the length of the handle body 110. When the inner tube 112 and the outer tube 111 are locked together, they are relatively fixed, and the length of the handle body 110 is fixed.

[0193] The locking pin assembly 142 can be used to control the relative sliding or relative fixing between the inner tube 112 and the outer tube 111.

[0194] Furthermore, by providing the locking element 130, the position of the locking element 130 allows the handle body 110 to perform its rotational movement relative to the machine body and its extension / retraction movement separately. In other words, when the handle body 110 rotates relative to the machine body, the inner tube 112 and the outer tube 111 can be relatively fixed, and the length of the handle body 110 cannot be adjusted. When the inner tube 112 and the outer tube 111 slide relative to each other, the rotation angle of the handle body 110 relative to the machine body can remain fixed, and the rotation angle of the handle body 110 relative to the machine body cannot be adjusted.

[0195] This design facilitates user control of the handle body 110, preventing the handle body 110 from becoming difficult to operate when its flipping and telescopic movements occur simultaneously. Furthermore, when flipping and telescopic movements occur simultaneously, they interfere with each other, potentially causing malfunctions and negatively impacting the user experience.

[0196] See also some of the possible implementation methods. Figure 8 and Figure 9 As shown, in this embodiment of the application, when at least a portion of the locking member 130 is located in the mating groove 1221a, the handle body 110 can be rotated relative to the machine body, and the locking pin assembly 142 locks the inner tube 112 and the outer tube 111. When at least a portion of the locking member 130 is located in the limiting groove 140a, the rotational movement of the handle body 110 relative to the machine body is locked, and the locking pin assembly 142 unlocks the inner tube 112 and the outer tube 111.

[0197] In this embodiment, the movement of the locking member 130 within the handle body 110 cooperates with the locking pin assembly 142, enabling the handle body 110 to perform flipping and telescopic movements in stages.

[0198] Specifically, when at least part of the locking member 130 is located in the mating groove 1221a, the folding mechanism 120 can move so that the handle body 110 can engage or flip relative to the body. At this time, the inner tube 112 and the outer tube 111 are locked by the locking pin assembly 142, so that the inner tube 112 and the outer tube 111 are relatively fixed during the flipping of the handle body 110.

[0199] When at least part of the locking member 130 is in the limiting groove 140a, the inner tube 112 and the outer tube 111 can be unlocked by the locking pin assembly 142, so that the length of the handle body 110 can be adjusted by the relative sliding of the inner tube 112 and the outer tube 111. At this time, the position of the locking member 130 prevents the handle body 110 from being flipped relative to the body.

[0200] Therefore, after adjusting the angle at which the handle body 110 is rotated relative to the main body, the inner tube 112 and the outer tube 111 can be adjusted to slide relative to each other to adjust the length of the handle body 110. Alternatively, the distance between the inner tube 112 and the outer tube 111 can be adjusted before rotating the handle body 110 relative to the main body. This is not limited in this embodiment.

[0201] See also some of the possible implementation methods. Figures 8 to 11 As shown, in this embodiment of the application, the transmission component 141 moves forward or backward within the inner tube 112 to drive the locking member 130 to switch between the limiting groove 140a and the mating groove 1221a.

[0202] In this embodiment, the different movement directions of the transmission component 141 within the inner tube 112 can be used to drive the locking component 130 to switch between the limiting groove 140a and the mating groove 1221a, thereby achieving the switching between the flipping motion and the telescopic motion of the handle body 110.

[0203] In some examples, the transmission assembly 141 can move along the length of the outer sleeve 111. The length of the outer sleeve 111 can be the same as its axial direction.

[0204] In some examples, the handle assembly 100, in its initial state, may have a flat angle between the handle body 110 and the adapter rod 160, so that the camera body is in an upright position. The handle body 110 is not rotated relative to the camera body.

[0205] During the cleaning process of the cleaning equipment, there are many scenarios in low-ceilinged spaces. Therefore, in the initial state, the handle assembly 100 can be set with the locking piece 130 located in the mating groove 1221a to facilitate the rotation of the handle body 110 relative to the machine body at any time. This allows the handle body 110 to be quickly rotated relative to the machine body when encountering various low-ceilinged space scenarios.

[0206] It should be noted that the embodiments of this application do not limit the extension and retraction state of the handle body 110 in the initial state of the handle assembly 100.

[0207] refer to Figures 8 to 11 As shown, when the transmission assembly 141 moves to the left, the locking member 130 disengages from the mating groove 1221a and enters the limiting groove 140a. At this time, the handle body 110 cannot rotate. The locking pin assembly 142 can unlock the inner tube 112 and the outer tube 111 to adjust the length of the handle body 110. After the length of the handle body 110 is adjusted, the transmission assembly 141 can be reset to the right, causing the locking member 130 to disengage from the limiting groove 140a and enter the mating groove 1221a. At this time, the handle body 110 cannot extend or retract.

[0208] This application also provides a handle assembly 100 for use in cleaning equipment. The handle assembly 100 may include a handle body 110, a folding mechanism 120, and a telescopic mechanism 140.

[0209] The handle body 110 is directly or indirectly connected to the body of the cleaning equipment. The handle body 110 can be flipped relative to the body, and the inner tube 112 can be slidably connected to the outer tube 111. The outer tube 111 is provided with multiple gear adjustment holes 111a.

[0210] The folding mechanism 120 can be used to lock or flip the handle body 110 relative to the main body. The telescopic mechanism 140 includes a transmission assembly 141 and a locking pin assembly 142. The locking pin assembly 142 includes a locking pin body 1421. The transmission assembly 141 moves along the length of the outer sleeve 111 to drive the locking pin body 1421 to switch between a locked state and an unlocked state.

[0211] When the locking pin body 1421 is in the locked state, it is inserted into the gear adjustment hole 111a, and the inner tube 112 is fixed relative to the outer tube 111. When the locking pin body 1421 is in the unlocked state, it is disengaged from the gear adjustment hole 111a, and the inner tube 112 can slide relative to the outer tube 111.

[0212] In this embodiment, the outer tube 111 is provided with multiple gear adjustment holes 111a. When the locking pin body 1421 is inserted into any gear adjustment hole 111a, the inner tube 112 can be fixed relative to the outer tube 111. When the locking pin body 1421 corresponds to different gear adjustment holes 111a, the handle body 110 can have different lengths.

[0213] When the length of the handle body 110 needs to be adjusted, the locking pin body 1421 can first be in the unlocked state, allowing it to disengage from the original gear adjustment hole 111a. Since the inner tube 112 and outer tube 111 can slide relative to each other when the locking pin body 1421 is in the unlocked state, this relative sliding allows the locking pin body 1421 to align with the target gear adjustment hole 111a. The locking pin body 1421 can then be inserted into the target gear adjustment hole 111a to lock the inner tube 112 and outer tube 111, thereby completing the length adjustment of the handle body 110.

[0214] In some examples, multiple gear adjustment holes 111a can be spaced apart along the length of the outer sleeve 111.

[0215] In some examples, the number of gear adjustment holes 111a is not limited in the embodiments of this application. For example, there may be three, four, five or even more gear adjustment holes 111a.

[0216] In some examples, the present application does not limit the spacing between two adjacent gear adjustment holes 111a. For example, multiple gear adjustment holes 111a can be evenly distributed on the outer sleeve 111. In other words, the spacing between two adjacent gear adjustment holes 111a can be equal.

[0217] In some examples, the locking pin body 1421 may include a locking pin post. The inner tube 112 may have a clearance hole 112a. The locking pin post and the clearance hole 112a can be aligned. When the locking pin body 1421 is in the locked state, the locking pin post can be aligned with one of the gear adjustment holes 111a, allowing the locking pin post to be inserted into the gear adjustment hole 111a. The inner tube 112 and the outer tube 111 can remain fixed. When the locking pin body 1421 is in the unlocked state, the locking pin post and the gear adjustment hole 111a can be offset along the length of the outer tube 111, and the inner tube 112 and the outer tube 111 can slide relative to each other.

[0218] See also some of the possible implementation methods. Figure 9 As shown, when the locking pin body 1421 of this embodiment is in the locked state, the handle body 110 can be rotated relative to the main body. When the locking pin body 1421 is in the unlocked state, the handle body 110 can be engaged relative to the main body.

[0219] In this embodiment, when the locking pin body 1421 is in the locked state, it fixes the inner tube 112 and the outer tube 111 relative to each other, and the length of the handle body 110 remains fixed. At this time, the handle body 110 can be flipped relative to the machine body for cleaning low-lying spaces. When the locking pin body 1421 is in the unlocked state, it allows relative sliding between the inner tube 112 and the outer tube 111, and the handle body 110 can extend and retract. At this time, the handle body 110 can engage relative to the machine body, preventing it from flipping, thus ensuring that the flipping and extending movements of the handle body 110 do not interfere with each other.

[0220] See also some of the possible implementation methods. Figures 8 to 11 As shown, the pin assembly of this embodiment may include an adapter 1422. Part of the adapter 1422 may be connected to the transmission assembly 141. Part of the adapter 1422 may be connected to the locking pin body 1421. The adapter 1422 may move along the length of the outer sleeve 111. The adapter 1422 may drive the locking pin body 1421 to move axially along the position adjustment hole 111a.

[0221] In this embodiment, the movement direction of the locking pin body 1421 is the same as the axial direction of the gear adjustment hole 111a. Since the gear adjustment hole 111a is provided on the outer sleeve 111, and the locking pin body 1421 can be inserted into the gear adjustment hole 111a through the locking pin post, the axial direction of the gear adjustment hole 111a can be perpendicular to the length direction of the outer sleeve 111.

[0222] The adapter 1422 can be used to transmit force. The adapter 1422 can transmit the force of the transmission component to the locking pin assembly 142. Furthermore, the adapter 1422 can also be used to change the direction of the force. The adapter 1422 can convert the force of the transmission component along the length of the outer sleeve 111 into the force of the locking pin body 1421 moving axially along the gear adjustment hole 111a.

[0223] By setting the adapter 1422 to cooperate with the transmission assembly 141 and the locking pin assembly 142, the transmission assembly 141 and the locking pin assembly 142 can be arranged side by side in the axial direction of the gear adjustment hole 111a, which helps to save space inside the inner tube 112 along the length direction of the outer tube 111, thus simplifying the internal structure.

[0224] See also some of the possible implementation methods. Figure 9 and Figure 11 As shown, the adapter 1422 of this embodiment may be provided with a first tilting adapter portion 1422a. The locking pin body 1421 may be provided with a second tilting adapter portion 1421a. The first tilting adapter portion 1422a and the second tilting adapter portion 1421a can cooperate and move.

[0225] In this embodiment, the first tilting adapter 1422a is tilted relative to the movement direction of the adapter 1422. The second tilting adapter 1421a cooperates with the first tilting adapter 1422a. The first tilting adapter 1422a and the second tilting adapter 1421a can be used to switch the direction of the force applied to the transmission assembly 141.

[0226] refer to Figures 8 to 11 As shown, when the transmission assembly 141 moves to the left along the length of the outer sleeve 111, the transmission assembly 141 can drive the adapter 1422 to move to the left. The first inclined adapter 1422a and the second inclined adapter 1421a move in coordination. The leftward movement of the adapter 1422 provides upward movement space for the locking pin body 1421. The locking pin body 1421 can move upward so that the locking pin can disengage from the gear adjustment hole 111a, and the inner tube 112 and the outer sleeve 111 can slide relative to each other.

[0227] Correspondingly, when the transmission assembly 141 moves to the right along the length of the outer tube 111, the transmission assembly 141 can drive the adapter 1422 to move to the right. The rightward movement of the adapter 1422 can push the locking pin body 1421 downward, so that the locking pin is inserted into the gear adjustment hole 111a, and the inner tube 112 and the outer tube 111 are relatively fixed.

[0228] See also some of the possible implementation methods. Figure 8As shown, the locking pin assembly 142 of this application embodiment may include a fixing member 1423. The fixing member 1423 may be disposed in the inner tube 112. The fixing member 1423 is provided with a slide 1423a that can accommodate at least a portion of the adapter 1422 and at least a portion of the locking pin body 1421. The slide 1423a extends along the length direction of the outer tube 111.

[0229] The fixing member 1423 may be provided with a limiting groove 1423b. One of the adapter 1422 and the transmission assembly 141 may pass through the limiting groove 1423b to connect with the other.

[0230] In this embodiment, the fixing member 1423 provides movement space for the adapter 1422. The slide 1423a of the fixing member 1423 guides the movement direction of the adapter 1422.

[0231] The limiting groove 1423b can be used to connect the transmission assembly 141 and the adapter 1422, so that the movement of the transmission assembly 141 drives the movement of the adapter 1422. Furthermore, the limiting groove 1423b can limit the movement of the adapter 1422, thereby restricting its range of motion along the length of the outer sleeve 111, which helps improve the reliability of the fit between the locking pin and the gear adjustment hole 111a.

[0232] In some examples, a portion of the adapter 1422 may extend outside the limiting groove 1423b to connect with the transmission assembly 141. Alternatively, a portion of the transmission assembly 141 may extend into the slide rail 1423a through the limiting groove 1423b to connect with the adapter 1422, which is not limited in this embodiment.

[0233] See also some of the possible implementation methods. Figure 10 As shown, the telescopic mechanism 140 of this embodiment may further include a telescopic trigger 143. The telescopic trigger 143 is connected to the transmission assembly 141. The telescopic trigger 143 is used to drive the transmission assembly 141 to move.

[0234] When the telescopic trigger 143 is not triggered, the adapter 1422 drives the locking pin body 1421 to insert into the gear adjustment hole 111a. When the telescopic trigger 143 is triggered, the adapter 1422 can disengage the locking pin body 1421 from the gear adjustment hole 111a.

[0235] In this embodiment, the telescopic trigger 143 provides an operable structure for the user. By triggering the telescopic trigger 143, the user can switch the locking pin body 1421 between a locked state and an unlocked state.

[0236] When the current length of the handle body 110 provides a comfortable user experience, the telescopic trigger 143 can be left untriggered. At this time, the locking pin of the locking pin body 1421 is inserted into the gear adjustment hole 111a, the inner tube 112 and the outer tube 111 are relatively fixed, and the length of the handle body 110 is fixed. When it is necessary to adjust the length of the handle body 110, the telescopic trigger 143 can be triggered. The telescopic trigger 143 can drive the transmission component 141 to move, thereby driving the adapter 1422 to transmit force to the locking pin body 1421. The locking pin of the locking pin body 1421 can disengage from the gear adjustment hole 111a, allowing the inner tube 112 and the outer tube 111 to slide relative to each other, thus adjusting the length of the handle body 110.

[0237] In some examples, the telescopic trigger 143 can be flipped relative to the handle body 110 so that the transmission assembly 141 can drive the adapter 1422 to move along the length of the outer sleeve 111.

[0238] Specifically, refer to Figures 8 to 11 In the indicated direction, when the telescopic trigger 143 rotates counterclockwise, the transmission assembly 141 can apply a leftward force to the adapter 1422. The adapter 1422 moves leftward within the slide rail 1423a, allowing the first tilting adapter 1422a to provide space for the locking pin body 1421 to move upward. The locking pin body 1421 can move upward to disengage from the gear adjustment hole 111a. Correspondingly, when the telescopic trigger 143 resets clockwise, the adapter 1422 moves rightward within the slide rail 1423a. The first tilting adapter 1422a can press the locking pin body 1421 downward so that when the locking pin body 1421 aligns with the gear adjustment hole 111a, the locking pin post of the locking pin body 1421 can be inserted into the gear adjustment hole 111a.

[0239] See also some of the possible implementation methods. Figure 11 As shown, the locking pin assembly 142 may further include a telescopic reset member 1424. One end of the telescopic reset member 1424 is connected to the fixing member 1423. The other end of the telescopic reset member 1424 is connected to the adapter 1422. The telescopic reset member 1424 can be used to drive the telescopic trigger member 143 to reset to an untriggered state.

[0240] In the embodiments of this application, reference is made to Figures 8 to 11In the indicated direction, when the user triggers the telescopic trigger 143 to rotate counterclockwise, the transmission assembly 141 causes the adapter 1422 to move to the left. At this time, the telescopic reset member 1424 deforms under the force of the adapter 1422. Due to the leftward movement of the adapter 1422, the locking pin of the locking pin body 1421 disengages from the gear adjustment hole 111a. When the user releases the force on the telescopic trigger 143, the leftward force exerted by the transmission assembly 141 on the adapter 1422 is released. The telescopic reset member 1424 then releases its deformation force, which drives the adapter 1422 to move to the right, thereby driving the locking pin of the locking pin body 1421 to insert into the gear adjustment hole 111a. On the other hand, since the adapter 1422 is connected to the transmission assembly 141, the telescopic reset member 1424 can drive the transmission assembly 141 to move to the right through the adapter 1422, thereby causing the telescopic trigger member 143 to move clockwise to reset.

[0241] In some examples, the telescopic reset element 1424 may be, but is not limited to, a spring.

[0242] See also some of the possible implementation methods. Figures 8 to 11 As shown, the locking pin assembly 142 may further include a locking pin reset member 1425. Along the axial direction of the gear adjustment hole 111a, one end of the locking pin reset member 1425 is connected to the fixing member 1423, and the other end of the locking pin reset member 1425 is connected to the locking pin body 1421. The locking pin reset member 1425 can be used to drive the locking pin body 1421 out of the gear adjustment hole 111a when the telescopic trigger member 143 is triggered.

[0243] In this embodiment, the locking pin reset member 1425 can be used to drive the locking pin body 1421 from a locked state to an unlocked state. When the locking pin body 1421 is in the locked state, the locking pin reset member 1425 can deform. When the adapter 1422 moves to the left, the downward force exerted by the adapter 1422 on the locking pin body 1421 is released. At this time, the locking pin reset member 1425 can release the deformation force, so that the locking pin of the locking pin body 1421 can disengage from the gear adjustment hole 111a.

[0244] See also some of the possible implementation methods. Figure 8 As shown in Figures 11 to 12, the handle assembly 100 may further include a locking member 130. The transmission assembly 141 can drive the locking member 130 to move within the handle body 110. The folding mechanism 120 is provided with a mating groove 1221a; when the locking member 130 engages with the mating groove 1221a, the locking pin body 1421 is in a locked state. The telescopic mechanism 140 is provided with a limiting groove 140a; when the locking member 130 engages with the limiting groove 140a, the locking pin body 1421 is in an unlocked state.

[0245] In this embodiment, the locking member 130 switches between the mating groove 1221a and the limiting groove 140a, and the locking pin assembly 142 switches between the locked state and the unlocked state. Therefore, by the position of the locking member 130 and the state of the locking pin assembly 142, the flipping movement and the telescopic movement of the handle body 110 can be made independent of each other.

[0246] Specifically, when at least part of the locking member 130 is located in the mating groove 1221a, the folding mechanism 120 can move so that the handle body 110 can engage or flip relative to the body. At this time, the locking pin assembly 142 is in a locked state. By locking the inner tube 112 and the outer tube 111 through the locking pin assembly 142, the inner tube 112 and the outer tube 111 can be relatively fixed during the flipping process of the handle body 110.

[0247] When at least part of the locking member 130 is located in the limiting groove 140a, the locking pin assembly 142 is in the unlocked state. The inner tube 112 and the outer tube 111 can be unlocked by the locking pin assembly 142, so that the length of the handle body 110 can be adjusted by the relative sliding of the inner tube 112 and the outer tube 111. Furthermore, the position of the locking member 130 prevents the handle body 110 from being flipped relative to the body.

[0248] See also some of the possible implementation methods. Figure 10 As shown, the transmission assembly 141 may include a connecting rod 1411 and a slider 1412. One end of the connecting rod 1411 is connected to the slider 1412, and the other end of the connecting rod 1411 is connected to the telescopic trigger 143.

[0249] The slider 1412 can be used to drive the adapter 1422 to move along the length of the outer tube 111, and the slider 1412 can also be used to drive the locking member 130 to switch between the folding mechanism 120 and the slider 1412.

[0250] In this embodiment, the connecting rod 1411 and the slider 1412 can be used to transmit force so that when the telescopic trigger 143 is triggered, the adapter 1422 can be driven to move through the connecting rod 1411 and the slider 1412, thereby causing the locking pin assembly 142 to be in a locked or unlocked state. The coordinated movement of the connecting rod 1411 and the slider 1412 has the advantages of simple structure and high reliability.

[0251] In some examples, link 1411 is rotatably connected to telescopic trigger 143. Link 1411 is also rotatably connected to slider 1412. Slider 1412 can move along the length of outer sleeve 111.

[0252] See also some of the possible implementation methods. Figures 8 to 11As shown, the handle assembly 100 may further include a linkage 1222. At least a portion of the linkage 1222 may be located in the inner tube 112. The linkage 1222 and the inner wall of the inner tube 112 form an internal space that allows the transmission assembly 141 to move along the length of the outer tube 111.

[0253] In this embodiment, the linkage 1222 and the locking member 130 can move synchronously. When the locking member 130 is located in the limiting groove 140a, the sliding of the linkage 1222 can be used to realize the relative sliding of the inner tube 112 and the outer tube 111. Furthermore, an internal space that guides the slider 1412 can be formed between the linkage 1222 and the inner wall of the inner tube 112.

[0254] See also some of the possible implementation methods. Figures 8 to 11 As shown, the folding mechanism 120 may further include a first traction body 1221, which is slidably connected to the linkage member 1222. The first traction body 1221 is provided with a mating groove 1221a, and the linkage member 1222 is provided with a locking hole 122a through which the locking member 130 passes. When the locking member 130 is located in the locking hole 122a and the mating groove 1221a, the first traction body 1221 and the linkage member 1222 move synchronously, and the first traction body 1221 drives the handle body 110 to engage or flip relative to the body.

[0255] See also some of the possible implementation methods. Figure 2 As shown, the slider 1412 is provided with a limiting groove 140a. When the locking member 130 is located in the limiting groove 140a and the locking hole 122a, the transmission assembly 141 is used to adjust the extension length of the inner tube 112 relative to the outer tube 111.

[0256] This application also provides a cleaning device, see [link to relevant documentation] Figure 10 As shown, the cleaning device may include a body and a handle assembly 100 as described in any of the above embodiments. The handle assembly 100 is connected to the body.

[0257] In some examples, the cleaning equipment may also include a clean water tank and a wastewater tank. The clean water tank and wastewater tank may be mounted on the floor brush assembly or on the main body. Alternatively, one of the clean water tank and wastewater tank may be mounted on the floor brush assembly, and the other may be mounted on the main body. This application does not impose any limitations on the embodiments described.

[0258] This application also provides a cleaning system. The cleaning system may include a base or a base station. The cleaning equipment may be placed on the base or base station.

[0259] In some examples, the base can be used to clean and dry the roller brush to prevent it from being damp for extended periods, which could lead to odors or bacteria.

[0260] In some examples, the base station may have a charging function. When the cleaning equipment is placed on the base station, it can charge the base station and automatically supply and drain water. The base and the base station can be separate structures, or they can be an integrated structure; this is not limited in the embodiments of this application.

[0261] See Figure 10 As shown, the handle assembly 100 of this application embodiment can be applied to cleaning equipment. The handle assembly 100 may include a handle body 110, a folding mechanism 120, a locking member 130, and a telescopic mechanism 140.

[0262] The handle body 110 is directly or indirectly connected to the body of the cleaning equipment. The handle body 110 can be flipped relative to the body. The inner tube 112 is slidably connected to the outer tube 111, and the outer tube 111 is provided with a plurality of gear adjustment holes 111a spaced apart along its length.

[0263] The folding mechanism 120 can be disposed on the handle body 110. The folding mechanism 120 has a plurality of mating grooves 1221a spaced apart along its length. The locking member 130 cooperates with the mating grooves 1221a to enable the folding mechanism 120 to drive the handle body 110 to engage or flip relative to the body.

[0264] Telescopic mechanism 140 is disposed on handle body 110. Telescopic mechanism 140 may include locking pin assembly 142. Locking pin assembly 142 is inserted into or disengaged from gear adjustment hole 111a to lock outer tube 111 and inner tube 112 or to enable inner tube 112 to telescopically slide relative to outer tube 111;

[0265] The number of gear adjustment holes 111a is less than or equal to the number of mating grooves 1221a, and the distance between two adjacent gear adjustment holes 111a is equal to the distance between two adjacent mating grooves 1221a.

[0266] In this embodiment, the outer tube 111 is provided with a plurality of gear adjustment holes 111a spaced apart along its length. The locking pin assembly 142, corresponding to different gear adjustment holes 111a, can be used to adjust the relative sliding distance between the inner tube 112 and the outer tube 111, allowing the handle body 110 to extend and retract, thus enabling the handle body 110 to have different length settings. Since the locking member 130 cooperates with the mating groove 1221a, it can be used to drive the handle body 110 to engage or rotate relative to the machine body. Therefore, by setting the number of gear adjustment holes 111a to be less than or equal to the number of mating grooves 1221a, and the distance between two adjacent gear adjustment holes 111a to be equal to the distance between two adjacent mating grooves 1221a, the handle body 110 can rotate relative to the machine body when corresponding to different length settings, thereby enabling the handle body 110 to rotate relative to the machine body and also to extend and retract.

[0267] Specifically, taking the matching of the number of gear adjustment holes 111a with the number of mating grooves 1221a as an example, the gear adjustment holes 111a and the mating grooves 1221a can correspond one-to-one. The locking pin assembly 142 is inserted into one of the gear adjustment holes 111a so that when the length of the handle body 110 can meet the comfort of use, the locking member 130 can be located in the mating groove 1221a. At this time, the folding mechanism 120 can be used to drive the handle body 110 to engage or flip relative to the body.

[0268] When the locking pin assembly 142 moves to another gear adjustment hole 111a, the locking member 130 can be positioned exactly in the corresponding mating groove 1221a, so that the handle body 110 can be flipped relative to the machine body when the length of the handle body 110 is fixed.

[0269] For example, refer to Figures 8 to 11 As shown, four gear adjustment holes 111a are provided sequentially from left to right. Four mating grooves 1221a are also provided sequentially from left to right. When the locking pin assembly 142 is inserted into the first gear adjustment hole 111a on the left, the locking member 130 can be located within the first mating groove 1221a on the left. When the locking pin assembly 142 is inserted into the second gear adjustment hole 111a on the left, the locking member 130 can be located within the second mating groove 1221a on the left. And so on, which will not be described further.

[0270] It should be noted that the mating groove 1221a and the gear adjustment hole 111a can be staggered along the length of the outer sleeve 111, or the mating groove 1221a and the gear adjustment hole 111a can be set as follows: Figures 8 to 11 The directions shown correspond to vertically, but are not limited in this embodiment.

[0271] See also some of the possible implementation methods. Figure 8 As shown, when the locking pin assembly 142 of this application embodiment is inserted into the gear adjustment hole 111a, the locking member 130 is located in the mating groove 1221a.

[0272] In this embodiment, when the locking pin assembly 142 is inserted into the gear adjustment hole 111a, the inner tube 112 and the outer tube 111 are locked together. At this time, the locking member 130 is located in the mating groove 1221a to drive the handle body 110 to engage or rotate relative to the machine body. Therefore, the engagement or rotation of the handle body 110 relative to the machine body and the extension / retraction movement of the handle body 110 cannot be performed simultaneously. In other words, the engagement or rotation of the handle body 110 relative to the machine body and the extension / retraction movement of the handle body 110 need to be operated in steps, which helps to improve the reliability of the engagement or rotation of the handle body 110 relative to the machine body and the extension / retraction movement of the handle body 110, and also allows the user to conveniently control the state of the handle body 110.

[0273] See also some of the possible implementation methods. Figure 10 As shown, in the embodiment of this application, the distribution direction of the gear adjustment hole 111a is parallel to the distribution direction of the mating groove 1221a.

[0274] In this embodiment, by setting the distribution direction of the gear adjustment holes 111a to be parallel to the distribution direction of the mating grooves 1221a, the inner tube 112 can slide relative to the outer tube 111. When the locking pin assembly 142 is inserted into different gear adjustment holes 111a, the locking member 130 can be guaranteed to be located in the corresponding mating groove 1221a. This avoids the locking member 130 from shifting or disengaging from the mating groove 1221a, which could affect the possibility of the handle body 110 engaging or rotating relative to the body.

[0275] See also some of the possible implementation methods. Figure 10 As shown, when the inner tube 112 slides telescopically relative to the outer tube 111, the locking pin assembly 142 slides past at least one gear adjustment hole 111a, and the locking member 130 slides past the same number of mating grooves 1221a.

[0276] In this embodiment, during the relative sliding of the inner tube 112 and the outer tube 111, the number of gear adjustment holes 111a that the locking pin assembly 142 passes through is equal to the number of mating grooves 1221a that the locking member 130 slides through. This ensures that the handle body 110 can achieve locking or flipping movement relative to the machine body when corresponding to different gear lengths, thus preventing the locking member 130 from entering the misaligned mating groove 1221a, which could affect the locking or flipping movement of the handle body 110 relative to the machine body, or even affect the telescopic movement of the handle body 110.

[0277] It is easy to understand that the distance the handle body 110 extends and retracts can be equal to the sum of the distances between all the mating grooves 1221a through which the locking member 130 slides.

[0278] For example, refer to Figures 8 to 11 In the direction shown, when the number of mating grooves 1221a and gear adjustment holes 111a are the same, when the locking pin assembly 142 moves from the first gear adjustment hole 111a on the left to correspond to the third gear adjustment hole 111a on the left, the locking member 130 moves from the first mating groove 1221a on the left to correspond to the third mating groove 1221a on the left.

[0279] See also some of the possible implementation methods. Figure 10 As shown, the telescopic mechanism 140 of this embodiment may include a transmission assembly 141. The transmission assembly 141 may be provided with a limiting groove 140a. The transmission assembly 141 moves along the length direction of the outer sleeve 111 to drive the locking member 130 to switch between the mating groove 1221a and the limiting groove 140a.

[0280] The transmission assembly 141 is connected to the locking pin assembly 142. The transmission assembly 141 drives the locking pin assembly 142 to insert into or disengage from the gear adjustment hole 111a. When the locking pin assembly 142 disengages from the gear adjustment hole 111a, the locking member 130 can be located in the limiting groove 140a.

[0281] In this embodiment, the transmission assembly 141 can be used to drive the locking member 130 to switch between the mating groove 1221a and the limiting groove 140a. When the locking member 130 is located in the mating groove 1221a, the locking pin assembly 142 locks the outer tube 111 and the inner tube 112 to fix the length of the handle body 110. At this time, the handle body 110 can be engaged or flipped relative to the machine body. When the locking member 130 is located in the limiting groove 140a, the locking member 130 is disengaged from the mating groove 1221a, and the handle body 110 cannot be engaged or flipped relative to the machine body. The transmission assembly 141 can cause the locking pin assembly 142 to disengage from the gear adjustment hole 111a to realize the telescopic sliding of the inner tube 112 relative to the outer tube 111.

[0282] Therefore, by setting the locking element 130 to switch between the mating groove 1221a and the limiting groove 140a, the synchronous movement of the handle body 110 relative to the machine body in engagement or rotation and the telescopic sliding of the inner tube 112 relative to the outer tube 111 can be restricted. In other words, the engagement or rotation of the handle body 110 relative to the machine body and the telescopic sliding of the inner tube 112 relative to the outer tube 111 need to be performed step by step.

[0283] In some examples, when the locking member 130 is located in the mating groove 1221a, the mating groove 1221a and the limiting groove 140a can be staggered in the length direction of the outer sleeve 111 to prevent the locking member 130 from disengaging from the mating groove 1221a into the limiting groove 140a.

[0284] See also some of the possible implementation methods. Figures 8 to 11 As shown, the folding mechanism 120 and the telescopic mechanism 140 are arranged side by side along the radial direction of the outer sleeve 111. The opening directions of the mating groove 1221a and the limiting groove 140a are opposite to each other.

[0285] In this embodiment, the folding mechanism 120 and the telescopic mechanism 140 are arranged side by side along the radial direction of the outer sleeve 111, which can effectively utilize the internal space of the inner sleeve 112 and save the size of the inner sleeve 112 along its own length. The folding mechanism 120 and the telescopic mechanism 140 have a compact structure, which is conducive to realizing the miniaturization and weight reduction design of the cleaning equipment.

[0286] By setting the opening directions of the mating groove 1221a and the limiting groove 140a to be opposite, the locking component 130 can be easily switched between the two.

[0287] See also some of the possible implementation methods. Figure 10 As shown, the folding mechanism 120 may include a first traction body 1221 and a linkage member 1222. The first traction body 1221 is slidably connected to the linkage member 1222. The first traction body 1221 is provided with a mating groove 1221a, and the linkage member 1222 is provided with a locking hole 122a. When the locking pin assembly 142 is inserted into the gear adjustment hole 111a, the locking member 130 is located in the locking hole 122a and one of the mating grooves 1221a. The first traction body 1221 is used to drive the handle body 110 to engage or rotate relative to the body.

[0288] In this embodiment, when the locking member 130 is located in the locking hole 122a and one of the mating grooves 1221a, the locking member 130 can lock the first traction body 1221 and the linkage member 1222 together. The first traction body 1221 and the linkage member 1222 can move synchronously so that the handle body 110 can be engaged or rotated relative to the machine body through the first traction body 1221. At this time, since the locking pin assembly 142 is inserted into the gear adjustment hole 111a, the outer tube 111 and the inner tube 112 can be locked together, and the length of the handle body 110 cannot be adjusted.

[0289] See also some of the possible implementation methods. Figures 8 to 11As shown, the transmission assembly 141 of this embodiment may include a slider 1412 for driving the locking pin assembly 142. The slider 1412 may be provided with a limiting groove 140a. When the locking pin assembly 142 disengages from the gear adjustment hole 111a, the locking hole 122a corresponds to the limiting groove 140a. The locking member 130 is located within the locking hole 122a and the limiting groove 140a.

[0290] In this embodiment, at least a portion of the linkage 1222 may be located inside the inner tube 112. The sidewall of the linkage 1222 and the inner wall of the inner tube 112 may form a guide space for the slider 1412 to slide along the length of the outer tube 111.

[0291] The slider 1412, sliding along the length of the outer tube 111, can drive the locking member 130 to switch between the mating groove 1221a and the limiting groove 140a. Furthermore, it can also drive the locking pin assembly 142 to lock the outer tube 111 and the inner tube 112, or to enable the inner tube 112 to slide telescopically relative to the outer tube 111. Therefore, the movement of the slider 1412 can synchronously drive the locking pin assembly 142 and the locking member 130, so that when the locking pin assembly 142 corresponds to the gear adjustment hole 111a, the locking member 130 can be located in the mating groove 1221a corresponding to that gear adjustment hole 111a.

[0292] This application also provides a cleaning device, which may include a main body and a handle assembly 100 as described in any of the above embodiments. The handle assembly 100 is connected to the main body.

[0293] In some examples, the cleaning equipment may also include a clean water tank and a wastewater tank. The clean water tank and wastewater tank may be mounted on the floor brush assembly or on the main body. Alternatively, one of the clean water tank and wastewater tank may be mounted on the floor brush assembly, and the other may be mounted on the main body. This application does not impose any limitations on the embodiments described.

[0294] This application also provides a cleaning system. The cleaning system may include a base or a base station. The cleaning equipment may be placed on the base or base station.

[0295] In some examples, the base can be used to clean and dry the roller brush to prevent it from being damp for extended periods, which could lead to odors or bacteria.

[0296] In some examples, the base station may have a charging function. When the cleaning equipment is placed on the base station, it can charge the base station and automatically supply and drain water. The base and the base station can be separate structures, or they can be an integrated structure; this is not limited in the embodiments of this application.

[0297] See also some of the possible implementation methods. Figures 8 to 13As shown, the handle assembly 100 of this application embodiment can be applied to cleaning equipment. The handle assembly 100 may include a handle body 110, a folding mechanism 120, and a telescopic mechanism 140.

[0298] The handle body 110 is directly or indirectly connected to the body of the cleaning equipment. The handle body 110 can be flipped relative to the body, and the inner tube 112 can be slidably connected to the outer tube 111.

[0299] A folding mechanism 120 is disposed on the handle body 110. The folding mechanism 120 may include a folding trigger 121. The folding trigger 121 is disposed on the handle body 110. The folding trigger 121 is used to control the handle body 110 to engage or rotate relative to the main body.

[0300] A telescopic mechanism 140 is disposed on the handle body 110. The telescopic mechanism 140 includes a telescopic trigger 143. The telescopic trigger 143 is disposed on the handle body 110. The telescopic trigger 143 is used to control the sliding or locking of the inner tube 112 relative to the outer tube 111.

[0301] There is a barrier between the operation part 1211 of the folding trigger and the operation part 1431 of the telescopic trigger.

[0302] In this embodiment, by triggering the operation part 1211 of the folding trigger, the user can lock or flip the handle body 110 relative to the main body, so that the main body is in a flat position, which can then be used for cleaning low spaces. By triggering the operation part 1431 of the telescopic trigger, the user can control the inner tube 112 to slide or lock relative to the outer tube 111, thereby adjusting the length of the handle body 110 to suit users of different heights and different application scenarios.

[0303] Since both the operating part 1211 of the folding trigger and the operating part 1431 of the telescopic trigger are located on the handle body 110, when the user holds the handle body 110 to clean the surface to be cleaned, it is easy to accidentally touch the other when driving one of the operating parts 1211 of the folding trigger and the operating part 1431 of the telescopic trigger, thereby affecting the movement state of the handle body 110 and affecting the user's normal use.

[0304] Therefore, a barrier can be provided between the operating part 1211 of the folding trigger and the operating part 1431 of the telescopic trigger. This barrier can refer to a spatial barrier, where there can be a large gap between the operating parts 1211 and 1431 of the folding trigger, so that when the user triggers one, their finger is less likely to touch the other, thus reducing the possibility of accidental activation.

[0305] Alternatively, the barrier can be created by using a physical structure to block the operating part 1211 of the folding trigger and the operating part 1431 of the telescopic trigger. This way, when one is triggered, the barrier prevents the user from accessing the other, making the other less likely to be triggered.

[0306] See also some of the possible implementation methods. Figure 12 and Figure 13 As shown, the handle body 110 of this embodiment may further include a first grip portion 171 and a second grip portion 172. The first grip portion 171 and the second grip portion 172 may form a handle 170. At least one of the first grip portion 171 and the second grip portion 172 may be used to block the operation portion 1211 of the folding trigger and the operation portion 1431 of the telescopic trigger.

[0307] In this embodiment of the application, when using the cleaning device, the user can hold either the first grip portion 171 or the second grip portion 172. By using at least one of the first grip portion 171 and the second grip portion 172 to block the operation portion 1211 of the folding trigger and the operation portion 1431 of the telescopic trigger, when the user holds the handle 170 and triggers one of them, at least one of the first grip portion 171 and the second grip portion 172 can prevent the user's fingers from touching the other.

[0308] When the hand grips the first grip 171 or the second grip 172, the thumb and the other four fingers are located on either side of the first grip 171 or the second grip 172, and the other four fingers have high dexterity. The other four fingers can be used to trigger the folding trigger 121 and the telescopic trigger 143.

[0309] At least one of the first grip portion 171 and the second grip portion 172 can be used to block the operation portion 1211 of the folding trigger and the operation portion 1431 of the telescopic trigger. Specifically, it can include: the first grip portion 171 for blocking the operation portion 1211 of the folding trigger and the operation portion 1431 of the telescopic trigger; the second grip portion 172 for blocking the operation portion 1211 of the folding trigger and the operation portion 1431 of the telescopic trigger; or both the first grip portion 171 and the second grip portion 172 can be used to block the operation portion 1211 of the folding trigger and the operation portion 1431 of the telescopic trigger.

[0310] Taking the first grip portion 171 as an example of blocking the operation portions 1211 of the folding trigger and 1431 of the telescopic trigger, the operation portions 1211 and 1431 of the folding trigger can be located on opposite sides of the first grip portion 171. When the first grip portion 171 is held, one of the operation portions 1211 and 1431 of the folding trigger is located on the thumb side, and the other is located on the four-finger side. According to conventional usage, the folding trigger 121 and the telescopic trigger 143 are usually triggered by four fingers. Therefore, blocking the folding trigger 121 and the telescopic trigger 143 by the first grip portion 171 can prevent the simultaneous triggering of the folding trigger 121 and the telescopic trigger 143.

[0311] The second grip 172 can be used to block the operation part 1211 of the folding trigger and the operation part 1431 of the telescopic trigger. The principle is the same as that of the first grip 171, and will not be described again here.

[0312] When both the first gripping part 171 and the second gripping part 172 are used to block the operating part 1211 of the folding trigger and the operating part 1431 of the telescopic trigger, the distance between the operating part 1211 of the folding trigger and the operating part 1431 of the telescopic trigger is relatively far, making it difficult for the user to trigger the folding trigger 121 and the telescopic trigger 1431 at the same time.

[0313] Furthermore, when at least one of the first grip portion 171 and the second grip portion 172 can act as a barrier, it can serve to alert the user. When the user's finger touches the barrier, the barrier can alert the user, preventing the user's finger from continuing to move and thus avoiding accidental touches.

[0314] See also some of the possible implementation methods. Figure 12 and Figure 13 As shown, in the embodiments of this application, at least one of the first grip portion 171 and the second grip portion 172 forms a barrier to the telescopic trigger member 143, so that the telescopic trigger member 143 cannot be operated simultaneously when the folding trigger member 121 is operated with one hand.

[0315] In this embodiment, both the external force applied to the folding trigger 121 and the external force applied to the telescopic trigger 143 can originate from the hand holding the handle body 110. Therefore, by applying an external force to the folding trigger 121 while holding the handle 170 with one hand, the user can achieve the rotation of the handle body 110 relative to the main body with a single-handed operation. Similarly, by applying an external force to the telescopic trigger 143 while holding the handle 170 with one hand, the user can achieve the extension and retraction of the handle body 110 with a single-handed operation.

[0316] By setting at least one of the first grip portion 171 and the second grip portion 172 to block the telescopic trigger 143, the fingers of the hand will not trigger the telescopic trigger 143 when the folding trigger 121 is operated with one hand.

[0317] This application also provides a handle assembly 100, which can be applied to cleaning equipment. The handle assembly 100 may include a handle body 110, a grip 170, a folding mechanism 120, and a telescopic mechanism 140.

[0318] The handle body 110 is directly or indirectly connected to the body of the cleaning equipment. The handle body 110 can be flipped relative to the body, and the inner tube 112 is slidably connected to the outer tube 111. The grip 170 is connected to the inner tube 112. The grip 170 includes a first grip portion 171 and a second grip portion 172, with a gripping space 170a between the first grip portion 171 and the second grip portion 172.

[0319] The folding mechanism 120 includes a folding trigger 121, which controls the handle body 110 to engage or flip relative to the main body. The telescopic mechanism 140 includes a telescopic trigger 143, which controls the inner tube 112 to slide or lock relative to the outer tube 111.

[0320] Only one of the operating parts 1211 of the folding trigger and 1431 of the telescopic trigger is located in the gripping space 170a.

[0321] In this embodiment of the application, when only one of the operating part 1211 of the folding trigger and the operating part 1431 of the telescopic trigger is located in the gripping space 170a, the other can be located outside the gripping space 170a. Therefore, the first gripping part 171 and / or the second gripping part 172 can be used to block the operating part 1211 of the folding trigger and the operating part 1431 of the telescopic trigger, so that when one is triggered, the other is not easily touched.

[0322] The first grip portion 171 and the second grip portion 172 can form a gripping space 170a for accommodating fingers. When at least four of the user's fingers are located in the gripping space 170a, the movement direction of the cleaning device can be stably controlled.

[0323] See also some of the possible implementation methods. Figures 1 to 4 , Figure 12 and Figure 13 As shown, the grip 170 of this embodiment can be located at the end of the handle body 110 away from the main body. The operation portion 1211 of the folding trigger and the operation portion 1431 of the telescopic trigger are disposed near the grip 170.

[0324] In this embodiment, the main body can be used to connect the handle assembly 100 and the floor brush assembly. By setting the handle 170 at the end of the handle body 110 away from the main body, the handle 170 can be closer to the user, making it easier for the user to hold and thus allowing for more comfortable control of the cleaning equipment.

[0325] The folding trigger 121 and the telescopic trigger 143 can be located at the end of the inner tube 112 away from the body, and the operating part 1211 of the folding trigger and the operating part 1431 of the telescopic trigger can be set close to the grip 170, so that the user can trigger one of the folding trigger 121 and the telescopic trigger 143 with one hand when holding the grip 170.

[0326] In some examples, the folding trigger 121 and the telescopic trigger 143 may be located on the grip 170 or on the inner tube 112, and are not limited in this embodiment.

[0327] In some examples, the first grip 171 may be tilted relative to the inner tube 112, and the second grip 172 may be tilted relative to the inner tube 112, so as to facilitate the user's grip when cleaning the surface to be cleaned, thereby reducing wrist bending and relieving wrist fatigue.

[0328] See also some of the possible implementation methods. Figures 1 to 4 As shown, at least a portion of the first grip portion 171 is located above the second grip portion 172 relative to the surface to be cleaned, and the operating portion 1211 of the folding trigger is located in the grip space 170a. The operating portion 1431 of the telescopic trigger can be positioned close to the second grip portion 172.

[0329] Specifically, when a user holds the first grip 171, the thumb rests on the side of the first grip 171 facing away from the grip space 170a, while the other four fingers are located in the grip space 170a. These four highly flexible fingers can be used to trigger the folding trigger 121, causing the handle body 110 to rotate relative to the main body. At this time, the second grip 172 can block the operating part 1211 of the folding trigger and the operating part 1431 of the telescopic trigger. Therefore, the palm needs to cover the entire handle 170 (i.e., including the first grip 171 and the second grip 172) to touch the operating part 1211 of the folding trigger. This is difficult for most users of this height, thus reducing the possibility of the folding trigger 121 and the telescopic trigger 143 being triggered simultaneously.

[0330] It should be noted that in some application scenarios, the same user typically uses the cleaning equipment for extended periods to clean the surface. Therefore, after initially adjusting the length of the handle body 110, the user can maintain its current length without needing to adjust it for each cleaning operation. It's easy to understand that users frequently encounter different low-ceilinged spaces while cleaning the surface; therefore, the adjustment action of flipping the handle body 110 relative to the machine body is more frequent than the extension / retraction action of the handle body 110.

[0331] Since at least a portion of the first grip portion 171 is located above the second grip portion 172, the first grip portion 171 can be closer to the user, thus providing greater comfort for the user when holding the first grip portion 171 during cleaning. The user also grips the first grip portion 171 more frequently. Furthermore, since the folding trigger 121 is used more frequently than the telescopic trigger 143, the folding trigger 121 can be positioned within the grip space 170a, allowing it to be triggered when the first grip portion 171 is gripped at high frequencies.

[0332] See also some of the possible implementation methods. Figure 7 and Figure 13 As shown, the folding trigger 121 moves along the length of the outer sleeve 111. The operating part 1211 of the folding trigger moves away from the body to be triggered. The telescopic trigger 143 rotates relative to the telescopic handle body 110, and the operating part 1431 of the telescopic trigger deflects towards the grip 170 to be triggered.

[0333] In this embodiment, when the user holds the first grip portion 171, the folding trigger 121 can be driven to move by the index or middle finger. The direction in which the folding trigger 121 is triggered facilitates user operation, thus saving effort.

[0334] When the user holds the second grip portion 172, the thumb can be located within the grip space 170a, and the other four fingers can be located on the side of the second grip portion 172 facing away from the grip space 170a. The other four fingers can be used to drive the telescopic trigger 143. The direction in which the telescopic trigger 143 is triggered is designed to facilitate user operation, thus achieving a labor-saving effect.

[0335] In some examples, the operating part 1211 of the folding trigger may be, but is not limited to, a hook and loop structure. The operating part 1431 of the telescopic trigger may be, but is not limited to, a plate-shaped trigger.

[0336] See also some of the possible implementation methods. Figure 12 and Figure 13As shown, the telescopic trigger 143 of this embodiment rotates relative to the handle body 110. The second grip portion 172 is used to block the operating portion 1431 of the telescopic trigger and the operating portion 1211 of the folding trigger when the operating portion 1431 of the telescopic trigger rotates relative to the handle body 110 to its limit position.

[0337] In some examples, when the folding trigger 121 is located in the grip space 170a, the operating portion 1211 of the folding trigger and the operating portion 1431 of the telescopic trigger can be located on opposite sides of the second grip portion 172. The second grip portion 172 can be used to block the operating portion 1431 of the telescopic trigger and the operating portion 1211 of the folding trigger when the operating portion 1431 of the telescopic trigger is rotated to its limit position relative to the handle body 110.

[0338] In some examples, a control button may be provided on the side of the first grip portion 171 facing away from the grip space 170a. The folding trigger 121 and the control button may be located on opposite sides of the first grip portion 171. When holding the first grip portion 171, the user can operate the control button with their thumb and drive the operation part 1211 of the folding trigger with their other four fingers.

[0339] See also some of the possible implementation methods. Figures 8 to 11 As shown, the folding mechanism 120 may further include a traction component and an unlocking component 123. Along the length of the outer tube 111, the folding trigger 121 and the unlocking component 123 are respectively disposed at both ends of the traction component. The folding trigger 121 moves along the length of the outer tube 111 to drive the unlocking component 123 via the traction component to control the handle body 110 to engage or rotate relative to the machine body.

[0340] In this embodiment, when the folding trigger 121 is triggered, the folding trigger 121 can transmit force through the traction component to drive the unlocking component 123 to engage or rotate relative to the body. When the unlocking component 123 engages with the body, the handle body 110 is mutually constrained with the body, and the handle body 110 cannot be flipped. When the unlocking component 123 can rotate relative to the body, the body can be placed in a flat position for cleaning low-ceilinged spaces.

[0341] It is easy to understand that the operating part 1431 of the telescopic trigger can be exposed outside the grip 170, and the operating part 1211 of the folding trigger can also be exposed outside the grip 170, so as to facilitate user operation.

[0342] See also some of the possible implementation methods. Figures 8 to 11As shown, the telescopic mechanism 140 may further include a transmission assembly 141 and a locking pin assembly 142. One end of the transmission assembly 141 is connected to the telescopic trigger 143, and the other end of the transmission assembly 141 is connected to the locking pin assembly 142. The locking pin assembly 142 can be used to lock or unlock the length of the inner tube 112 extending beyond the outer tube 111.

[0343] In this embodiment of the application, when the telescopic trigger 143 is triggered, the telescopic trigger 143 can transmit force through the transmission component 141 to drive the locking pin component 142 to move, thereby locking the inner tube 112 or unlocking the length of the inner tube 112 extending out of the outer tube 111 through the locking pin component 142.

[0344] This application also provides a cleaning device, which may include a main body and a handle assembly 100 as described in any of the above embodiments. The handle assembly 100 is connected to the main body.

[0345] In some examples, the cleaning equipment may also include a clean water tank and a wastewater tank. The clean water tank and wastewater tank may be mounted on the floor brush assembly or on the main body. Alternatively, one of the clean water tank and wastewater tank may be mounted on the floor brush assembly, and the other may be mounted on the main body. This application does not impose any limitations on the embodiments described.

[0346] This application also provides a cleaning system. The cleaning system may include a base or a base station. The cleaning equipment may be placed on the base or base station.

[0347] In some examples, the base can be used to clean and dry the roller brush to prevent it from being damp for extended periods, which could lead to odors or bacteria.

[0348] In some examples, the base station may have a charging function. When the cleaning equipment is placed on the base station, it can charge the base station and automatically supply and drain water. The base and the base station can be separate structures, or they can be an integrated structure; this is not limited in the embodiments of this application.

[0349] See Figures 8 to 13 As shown, the handle assembly 100 of this application embodiment can be applied to cleaning equipment. The handle assembly 100 may include a handle body 110, a grip 170, a folding mechanism 120, and a telescopic mechanism 140.

[0350] The handle body 110 is directly or indirectly connected to the body of the cleaning equipment. The handle body 110 can be rotated relative to the body. The inner tube 112 is slidably connected to the outer tube 111. The handle 170 is located at the end of the inner tube 112 away from the body.

[0351] At least part of the folding mechanism 120 is located in the inner tube 112. The folding mechanism 120 includes a folding trigger 121, which is disposed on the grip 170 and is used to control the handle body 110 to engage or flip relative to the body.

[0352] The telescopic mechanism 140 and the folding mechanism 120 are arranged side by side inside the inner tube 112. The telescopic mechanism 140 includes a telescopic trigger 143, which is disposed on the handle 170. The telescopic trigger 143 is used to control the sliding or locking of the inner tube 112 relative to the outer tube 111.

[0353] The non-operating end of the folding trigger 121 is close to the non-operating end of the telescopic trigger 143, and the non-operating end of the telescopic trigger 143 and the non-operating end of the folding trigger 121 are mutually locked, so that the folding trigger 121 is locked when the telescopic trigger 143 is triggered.

[0354] In this embodiment, when the telescopic trigger 143 is triggered, the handle body 110 is telescopic, and the length of the handle body 110 is adjustable. By setting the non-operating end of the telescopic trigger 143 and the non-operating end of the folding trigger 121 to be mutually locked, the folding trigger 121 can be prevented from being triggered when the handle body 110 is telescopic. In other words, when the handle body 110 is telescopic, the flipping movement of the handle body 110 relative to the machine body can be locked. The telescopic and flipping movements of the handle body 110 are not performed simultaneously.

[0355] Therefore, the possibility that the simultaneous extension and retraction and flipping movements of the handle body 110 could make it difficult to control, thus affecting cleaning efficiency and user experience, can be reduced. The extension and retraction and flipping movements of the handle body 110 can be performed separately to improve the reliability of the extension and retraction movements.

[0356] This application also provides a handle assembly 100, which can be used in cleaning equipment. The handle assembly 100 may include a handle body 110, a grip 170, a folding mechanism 120, and a telescopic mechanism 140.

[0357] The handle body 110 is directly or indirectly connected to the body of the cleaning equipment. The handle body 110 can be rotated relative to the body. The inner tube 112 can be slidably connected to the outer tube 111.

[0358] At least a portion of the folding mechanism 120 is located within the inner tube 112. The folding mechanism 120 includes a folding trigger 121. The folding trigger 121 controls the handle body 110 to engage or flip relative to the body. The folding trigger 121 has a first engaging portion 1432.

[0359] The telescopic mechanism 140 and the folding mechanism 120 are arranged side by side inside the inner tube 112. The telescopic mechanism 140 includes a telescopic trigger 143, which is used to control the inner tube 112 to slide or lock relative to the outer tube 111. The telescopic trigger 143 is provided with a second engaging part 1212 that cooperates with the first engaging part 1432.

[0360] When the telescopic trigger 143 is triggered, the first engaging part 1432 and the second engaging part 1212 can engage with each other, and the folding trigger 121 is locked.

[0361] In this embodiment, the folding trigger 121 can be used to realize the flipping movement of the handle body 110 relative to the main body. The telescopic trigger 143 can be used to realize the telescopic movement of the handle body 110. By setting the first engaging part 1432 and the second engaging part 1212 to engage with each other, the folding trigger 121 can be locked when the telescopic trigger 143 is triggered, so that the flipping movement and telescopic movement of the handle body 110 can be distributed, which helps to improve the reliability of the telescopic movement and flipping movement of the handle body 110.

[0362] Specifically, when the telescopic trigger 143 is activated, it allows the handle body 110 to extend or retract, enabling relative sliding between the inner tube 112 and the outer tube 111 to adjust the overall length of the handle body 110. At this time, the telescopic trigger 143 and the folding trigger 121 can be locked together through the cooperation of the first engaging part 1432 and the second engaging part 1212, preventing the handle body 110 from flipping relative to the main body.

[0363] The non-operating ends of the telescopic trigger 143 and the folding trigger 121 can be close to each other to facilitate locking the folding trigger 121 by the action of the telescopic trigger 143 when it is triggered. It should be noted that when the handle 170 is held with one hand and both the telescopic trigger 143 and the folding trigger 121 can be operated with one hand, the operating part 1431 of the telescopic trigger and the operating part 1211 of the folding trigger must be such that they cannot be triggered simultaneously with one hand.

[0364] See also some of the possible implementation methods. Figure 12 and Figure 13 As shown, when the telescopic trigger 143 of this embodiment is triggered, the telescopic trigger 143 can rotate relative to the handle body 110. The non-operating end of the telescopic trigger 143 is locked with the non-operating end of the folding trigger 121. When the telescopic trigger 143 is reset, the non-operating end of the telescopic trigger 143 is unlocked from the non-operating end of the folding trigger 121.

[0365] In this embodiment, when the telescopic trigger 143 is triggered, its movement causes the first engaging portion 1432 and the second engaging portion 1212 to engage with each other, thereby locking the non-operating end of the telescopic trigger 143 with the non-operating end of the folding trigger 121. When the telescopic trigger 143 is reset, its reset movement causes the first engaging portion 1432 and the second engaging portion 1212 to separate from each other, thereby releasing the constraint between them and unlocking the non-operating end of the telescopic trigger 143 and the non-operating end of the folding trigger 121.

[0366] Once the extension / retraction state of the handle body 110 is adjusted, the extension / retraction trigger 143 can be reset. At this time, the user can trigger the folding trigger 121 to allow the handle body 110 to flip relative to the main body.

[0367] See also some of the possible implementation methods. Figures 8 to 13 As shown, in this embodiment of the application, the folding trigger 121 moves along the length of the outer sleeve 111 to control the handle body 110 to engage or rotate relative to the machine body. When the non-operating end of the telescopic trigger 143 is locked with the non-operating end of the folding trigger 121, the telescopic trigger 143 is used to lock the folding trigger 121 from moving along the length of the outer sleeve 111.

[0368] In this example, when the telescopic trigger 143 is triggered, the telescopic trigger 143 can rotate relative to the handle body 110. The rotation of the telescopic trigger 143 can be used to lock the folding trigger 121 from moving along the length of the outer tube 111.

[0369] Specifically, refer to Figure 12 and Figure 13 In the direction shown, when the telescopic trigger 143 is triggered to rotate the operating part counterclockwise, the non-operating end of the telescopic trigger 143 can be brought close to the non-operating end of the folding trigger 121. When the telescopic trigger 143 moves to its limit position, the non-operating end of the telescopic trigger 143 can be connected to the non-operating end of the folding trigger 121, and the non-operating end of the telescopic trigger 143 can prevent the folding trigger 121 from moving in the triggered direction, thereby locking the folding trigger 121.

[0370] See also some of the possible implementation methods. Figures 8 to 11 As shown, the telescopic mechanism 140 of this application embodiment may include a telescopic reset member 1424. The telescopic reset member 1424 may be disposed on the handle body 110. The telescopic reset member 1424 is used to drive the telescopic trigger member 143 to reset, so that the non-operating end of the telescopic trigger member 143 is unlocked from the non-operating end of the folding trigger member 121.

[0371] In this embodiment of the application, when the user releases the triggering driving force on the telescopic reset member 1424, the telescopic reset member 1424 can be set to restore the telescopic reset member 1424 to the untriggered state, so that the non-operating end of the telescopic trigger member 143 can be separated from the non-operating end of the folding trigger member 121, thereby unlocking the non-operating end of the telescopic trigger member 143 from the non-operating end of the folding trigger member 121.

[0372] In some examples, the handle assembly 100 may also include a resilient reset member. When the triggering drive force of the telescopic reset member 1424 is released, the resilient reset member can be used to drive the telescopic trigger member 143 to reset.

[0373] For example, one end of the elastic reset member can be fixed to the inner wall of the grip 170, and the other end of the elastic reset member can be connected to the telescopic trigger member 143. When the telescopic trigger member 143 is triggered to rotate, the elastic reset member can generate elastic deformation. When the triggering driving force of the telescopic trigger member 143 is released, the elastic reset member can release elastic potential energy to drive the telescopic trigger member 143 to reset.

[0374] In some feasible embodiments, the telescopic trigger 143 and the telescopic reset 1424 can be located at both ends of the inner tube 112 along the length of the outer tube 111.

[0375] In this embodiment, since the non-operating end of the telescopic trigger 143 and the non-operating end of the folding trigger 121 are close to each other, and the space around the telescopic trigger 143 is limited, by setting the telescopic reset member 1424 at the end of the inner tube 112 away from the telescopic trigger 143, the structure at the non-operating end of the telescopic trigger 143 and the non-operating end of the folding trigger 121 can be simplified while realizing the reset movement of the telescopic trigger 143.

[0376] See also some of the possible implementation methods. Figures 8 to 13 As shown, the telescopic mechanism 140 may further include a transmission assembly 141 and a locking pin assembly 142. The transmission assembly 141 connects the telescopic trigger 143 and the locking pin assembly 142. The telescopic trigger 143 drives the locking pin assembly 142 to move, and the locking pin assembly 142 is used to lock or unlock the inner tube 112 and the outer tube 111. The telescopic reset member 1424 is connected to the locking pin assembly 142, and the telescopic reset member 1424 is used to drive the locking pin assembly 142 to reset.

[0377] In this embodiment of the application, the telescopic reset member 1424 can not only have the function of driving the telescopic trigger member 143 to reset, but also have the function of driving the locking pin assembly 142 to lock or unlock the inner tube 112 and the outer tube 111.

[0378] Specifically, when the telescopic trigger 143 is triggered, the transmission assembly 141 can transmit force to drive the locking pin assembly 142 to move. At this time, the locking pin assembly 142 can unlock the inner tube 112 and the outer tube 111 to adjust the length of the handle body 110. Furthermore, the movement of the locking pin assembly 142 can also put the telescopic reset member 1424 in a compressed state, and the telescopic reset member 1424 can accumulate the deformation force.

[0379] When the triggering driving force of the telescopic trigger 143 is released, on the one hand, the elastic reset member can drive the telescopic trigger 143 to reset, and on the other hand, the telescopic reset member 1424 can release elastic potential energy and transmit it to the telescopic trigger 143 through the transmission assembly 141, so that the telescopic trigger 143 can be reset.

[0380] See also some of the possible implementation methods. Figures 1 to 4 As shown, the folding trigger 121 and the telescopic trigger 143 of this embodiment can be located at the end of the handle body 110 away from the main body. There is a barrier between the operating part 1211 of the folding trigger and the operating part 1431 of the telescopic trigger.

[0381] By setting the folding trigger 121 and the telescopic trigger 143 to the end of the handle body 110 away from the main body, the folding trigger 121 and the telescopic trigger 143 can be brought closer to the user, so that the user can easily operate the folding trigger 121 and the telescopic trigger 143.

[0382] Since the folding trigger 121 and the telescopic trigger 143 are located at the same end of the handle body 110, by setting a barrier between the operating part 1211 of the folding trigger and the operating part 1431 of the telescopic trigger, when one of the folding trigger 121 and the telescopic trigger 143 is triggered, the barrier can make it difficult for the other to be triggered, so as to realize the step-by-step operation of the flipping movement and the telescopic movement of the handle body 110.

[0383] In some examples, the folding trigger 121 and the telescopic trigger 143 are located at the end of the inner tube 112 away from the body, and the operating part 1211 of the folding trigger and the operating part 1431 of the telescopic trigger can be set close to the grip 170, so that the user can trigger one of the folding trigger 121 and the telescopic trigger 143 with one hand when holding the grip 170.

[0384] See also some of the possible implementation methods. Figure 12 and Figure 13 As shown, one of the first engaging portion 1432 and the second engaging portion 1212 can be a locking groove structure, and the other of the first engaging portion 1432 and the second engaging portion 1212 can be a protruding structure.

[0385] When the telescopic trigger 143 is triggered, the protruding structure and the locking groove structure cooperate to constrain the folding trigger 121 to be triggered. When the telescopic trigger 143 is reset, the protruding structure disengages from the locking groove structure, and the folding trigger 121 is in a triggerable state.

[0386] In this embodiment, the structure is simple, easy to manufacture, and has high motion reliability due to the cooperation between the protruding structure and the locking groove structure.

[0387] refer to Figure 12 and Figure 13 Taking the direction shown, with the first engaging portion 1432 as a locking groove structure and the second engaging portion 1212 as a protruding structure as an example, when the telescopic trigger 143 is triggered, the second engaging portion 1212 on the telescopic trigger 143 can enter the first engaging portion 1432 of the folding trigger 121. Along the length direction of the outer sleeve 111, the second engaging portion 1212 and the first engaging portion 1432 have mutually constraining surfaces. The second engaging portion 1212 can constrain the first engaging portion 1432 to move to the right to the trigger position of the folding trigger 121, thereby locking the folding trigger 121. When the telescopic reset member 1424 resets, the second engaging portion 1212 can disengage from the first engaging portion 1432. The constraint force of the second engaging portion 1212 on the first engaging portion 1432 is released, at which time the folding trigger 121 can be triggered.

[0388] It should be noted that when the telescopic trigger 143 is reset, the reset movement of the telescopic reset member 1424 can cause the second engaging part 1212 to automatically disengage from the first engaging part 1432 without the need to apply other force or achieve this through other structures.

[0389] In some examples, when the first engaging portion 1432 is a locking groove structure, refer to Figure 12 and Figure 13 As shown, the opening of the first engaging portion 1432 can face downwards to facilitate the entry or exit of the second engaging portion 1212 of the telescopic trigger 143.

[0390] In some possible implementations, the grip 170 is located at the end of the inner tube 112 away from the fuselage, and the folding trigger 121 and the telescopic trigger 143 are located on the grip 170. The non-operating ends of the folding trigger 121 and the telescopic trigger 143 are located inside the grip 170.
