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, vacuum cleaners, etc. 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 a floor, a carpet or the like, and can simultaneously dry and remove sewage from the site, 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 is used to connect the handle assembly and the brush assembly. A user can hold the handle assembly to drive the brush assembly to clean the surface to be cleaned. The machine body of the conventional scrubber cannot be laid flat during cleaning, and the scrubber cannot effectively clean low spaces.

[0004] In the related art, the handle assembly is folded relative to the machine body by a pull rope structure, so that the included angle between the machine body and the surface to be cleaned can be adjusted when cleaning low spaces, and the machine body can be laid flat. However, since the pull rope cannot be extended or retracted, the handle assembly cannot realize the extension or retraction function, and therefore it is difficult to meet the use comfort of users with high height and to adapt to the use requirements of users with different heights. 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 handle assembly cannot realize the extension or retraction function after being folded, and cannot meet the use requirements of users with different heights and different application scenarios.

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

[0007] a handle main body, the handle main body being directly or indirectly connected with a machine body of the cleaning device, the handle main body being capable of being flipped relative to the machine body, the handle main body comprising an outer sleeve and an inner tube, the inner tube being slidably connected to the outer sleeve;

[0008] a folding mechanism, the folding mechanism being located in the handle main body; the folding mechanism comprising a folding trigger, a traction assembly and an unlocking member, the folding trigger driving the unlocking member through the traction assembly to flip the handle main body relative to the machine body; the traction assembly having a fixed length mode and an extension mode;

[0009] a locking member, the locking member moving in the handle main body to switch the fixed length mode and the extension mode of the traction assembly;

[0010] When the traction assembly is in the fixed-length mode, the handle body can be flipped relative to the machine body; when the traction assembly is in the telescopic mode, the inner tube can slide relative to the outer sleeve tube to achieve telescoping of the handle body.

[0011] The handle assembly provided in the application can make the traction assembly have a fixed-length mode and a telescopic mode by setting the locking member, can achieve flipping of the handle body relative to the machine body, can achieve length adjustment of the handle body, and can satisfy the use comfort of users of different heights and different application scenarios.

[0012] When the traction assembly is in the fixed-length mode, the handle body can be flipped relative to the machine body, so that the machine body can be in a lying state, and the brush assembly can be deep into a low space to clean the low space.

[0013] When the traction assembly is in the telescopic mode, the inner tube of the handle body can slide relative to the outer sleeve tube. By adjusting the length of the inner tube extending out of the outer sleeve tube, the length of the handle assembly can be adjusted, so that the use demand of users of different heights and different application scenarios can be satisfied. For example, when the machine body is in a standing state, for a user of small height, the length of the inner tube extending out of the outer sleeve tube can be small, or the inner tube does not extend out of the outer sleeve tube. For a user of high height, the inner tube can be adjusted to extend out of the outer sleeve tube by a long dimension, so as to increase the overall length of the handle assembly, thereby increasing the height of the holding end of the handle assembly and improving the use comfort of the user of high height.

[0014] In addition, when the machine body is in a lying state, the height of the holding end of the handle assembly is reduced. Especially for a user of high height, the inner tube can be adjusted to extend out of the outer sleeve tube by a long dimension, so that the height of the holding end of the handle assembly is increased, and the user can not need to bend or squat to control the handle assembly, which is beneficial to improve the use comfort of the cleaning equipment when cleaning a low space.

[0015] In a second aspect, the embodiments of the application provide a handle assembly, comprising:

[0016] a handle body connected with a machine body of a cleaning equipment, the handle body being flipable relative to the machine body, the handle body comprising an outer sleeve tube and an inner tube, the inner tube being slidably connected to the outer sleeve tube;

[0017] a folding mechanism in the handle body, the folding mechanism comprising a folding trigger, a traction assembly and an unlocking member, the folding trigger driving the unlocking member through the traction assembly to flip the handle body relative to the machine body, and the traction assembly having a fixed-length mode and a telescopic mode;

[0018] a locking member, which is movable in the handle body to have a locking position and a disengaging position;

[0019] When the locking member is in the locking position, the traction assembly is in a fixed-length mode, and the handle body can be flipped relative to the fuselage;

[0020] When the locking member is in the disengaging position, the traction assembly is in an extendible mode, and the inner tube can slide relative to the outer sleeve to achieve the telescoping of the handle body.

[0021] In this application, the locking member is used to switch the traction assembly between the fixed-length mode and the extendible mode. By switching the locking member between the locking position and the disengaging position, the traction assembly can be switched between the fixed-length mode and the extendible mode.

[0022] Specifically, when the locking member is in the locking position, the internal structure of the traction assembly can be locked, so that the overall length of the traction assembly remains fixed, and the traction assembly is in the fixed-length mode. At least part of the traction assembly can be used to drive the unlocking member to move, so that the handle body can be flipped relative to the fuselage. When the locking member is in the disengaging position, the locking between the internal structures of the traction assembly can be released, and the internal structures of the traction assembly can have relative movement, so that the overall length of the traction assembly can be extended or contracted, so that the inner tube can slide relative to the outer sleeve, thereby adjusting the length of the handle body.

[0023] It should be noted that, since the locking member is in the locking position, the traction assembly corresponds to the fixed-length mode, so it is difficult to achieve the sliding of the inner tube relative to the outer sleeve. Similarly, since the locking member is in the disengaging position, the traction assembly corresponds to the extendible mode, so it is difficult to achieve the flipping of the handle body relative to the fuselage.

[0024] Therefore, by providing the locking member with the locking position and the disengaging position, the flipping movement of the handle body relative to the fuselage and the sliding movement of the inner tube of the handle body relative to the outer sleeve can be independent of each other. During the flipping of the handle body relative to the fuselage, the inner tube and the outer sleeve can be relatively fixed, and the length of the handle body cannot be adjusted. After the angle of the flipping of the handle body relative to the fuselage is adjusted, the relative sliding of the inner tube and the outer sleeve can be adjusted to adjust the length of the handle body.

[0025] Similarly, during the relative sliding of the inner tube and the outer sleeve, the angle of the flipping of the handle body relative to the fuselage can remain fixed, and the angle of the flipping of the handle body relative to the fuselage cannot be adjusted. After the distance of the relative sliding of the inner tube and the outer sleeve is adjusted, the flipping angle of the handle body relative to the fuselage can be adjusted.

[0026] In this way, the user can conveniently control the handle body, and the possibility that the turning action and the telescopic action are simultaneously performed and the handle body is complicatedly controlled can be avoided.

[0027] According to one embodiment of the present application, the traction assembly comprises a first traction body and a linkage, the first traction body is connected with the unlocking member, and the linkage is connected with the folding trigger;

[0028] The locking member locks the first traction body and the linkage, so that the first traction body and the linkage move synchronously, and the traction assembly is in the fixed-length mode;

[0029] The locking member unlocks the first traction body and the linkage, so that the first traction body and the linkage slide relative to each other, and the traction assembly is in the telescopic mode.

[0030] In the present application, the first traction body and the linkage have two movement states to correspond to the fixed-length mode and the telescopic mode of the traction assembly. When the locking member is in the locking position, the first traction body and the linkage are locked by the locking member. The first traction body and the linkage can move synchronously, so 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 and the linkage can be used together to drive the unlocking member to move, so as to realize the turning of the handle body relative to the body.

[0031] When the locking member is in the disengaging position, the locking member can unlock the first traction body and the linkage. The first traction body and the linkage can slide relative to each other. One of the first traction body and the linkage can be used to make the inner tube slide relative to the outer sleeve. Since the first traction body is connected with the unlocking member, the movement of the first traction body will make the unlocking member move and affect the relative position of the handle body and the body. Therefore, the inner tube and the outer sleeve can slide relative to each other by the movement of the linkage. In other words, the first traction body can remain in a stationary state relative to the handle body, and the linkage slides relative to the first traction body to make the inner tube and the outer sleeve slide relative to each other.

[0032] According to one embodiment of the present application, at least part of the first traction body is located inside the linkage, the first traction body is provided with a matching groove capable of accommodating at least part of the locking member, and the linkage is provided with a locking hole capable of being penetrated by the locking member;

[0033] When the traction assembly is in the fixed-length mode, the matching groove and the locking hole correspond to each other, and the locking member is located in the matching groove and the locking hole;

[0034] When the traction assembly is in the telescopic mode, the matching groove and the locking hole are misaligned, the locking member is separated from the first traction body.

[0035] In the present application, the locking member can be switched between the locking position and the separation position by the cooperation between the locking member and the matching groove and the locking hole. In this way, the switching between the fixed-length mode and the telescopic mode of the traction assembly can be realized by a simple structure.

[0036] Specifically, the locking member can move in the inner tube. When the matching groove and the locking hole correspond to each other, at least part of the locking member can be located in the matching groove and the locking groove. The locking member can lock the first traction body and the linkage member to limit the relative sliding between the first traction body and the linkage member, so that the first traction body and the linkage member can move synchronously. The overall length of the traction assembly remains fixed, and the traction assembly is in the fixed-length mode. At this time, the handle body can be flipped relative to the body by driving the unlocking member to move by the first traction body.

[0037] When the matching groove and the locking hole are misaligned along the movement direction of the first traction body relative to the linkage member, the locking member can be separated from the matching groove. In other words, the locking member does not contact the first traction body. At this time, part of the locking member can be located in the locking hole of the linkage member, and the locking member contacts the linkage member. The locking member and the linkage member can move synchronously, so that the linkage member can slide relative to the first traction body.

[0038] According to one embodiment of the present application, a telescopic mechanism is further included, at least part of the telescopic mechanism moves in the inner tube;

[0039] The telescopic mechanism is provided with a limiting groove capable of accommodating at least part of the locking member;

[0040] When the traction assembly is in the telescopic mode, the limiting groove corresponds to the matching groove, the locking member is located in the limiting groove and the locking hole, and the locking member is separated from the matching groove.

[0041] In the present application, by providing the limiting groove capable of accommodating at least part of the locking member on the telescopic mechanism, the limiting groove can provide space for the locking member to separate from the matching groove, so as to realize the switching of the locking member from the locking position to the separation position.

[0042] The telescopic mechanism can move in the inner tube, and when the limiting groove on the telescopic mechanism corresponds to the locking hole on the linkage member, the locking member can be separated from the matching groove and fall into the matching groove through the locking hole on the linkage member. At this time, the linkage member can move relative to the first traction body, so that the traction assembly is in the telescopic mode.

[0043] When the traction assembly is in the telescopic mode, the locking member can be located in the locking hole and the limiting slot, so that the linkage member and the telescopic mechanism can operate synchronously. The linkage member moves along the axial direction of the inner tube to adjust the distance between the inner tube and the outer sleeve, thereby adjusting the overall length of the handle body.

[0044] Therefore, the linkage member can realize the associated movement of the folding mechanism and the telescopic mechanism, and the folding mechanism and the telescopic mechanism can not interfere with each other. When the locking member is in the locking position, the traction assembly is in the fixed-length mode, and the linkage member can be used together with the first traction body to drive the unlocking member to move, so as to realize the overturning of the handle body relative to the machine body. When the locking member is in the disengaging position, the traction assembly is in the telescopic mode, and the linkage member can move relative to the first traction body, and the linkage member can move synchronously with the telescopic mechanism to adjust the overall length of the handle body.

[0045] According to an embodiment of the present application, the locking hole is arranged on the side wall of the linkage member close to the telescopic mechanism;

[0046] When the traction assembly is in the fixed-length mode, the center of the locking member is aligned with the side wall in the extension direction of the side wall.

[0047] In the present application, when the telescopic mechanism moves to make the limiting slot correspond to the locking hole and the matching slot, by arranging the side wall of the linkage member to be aligned with the center of the locking member in the extension direction of the side wall, the switching of the locking member from the locking position to the disengaging position can be facilitated.

[0048] Specifically, when the telescopic mechanism moves to make the limiting slot correspond to the locking hole and the matching slot, on the one hand, the locking member can fall into the limiting slot under the action of its own gravity. The locking member can be disengaged from the matching slot of the first traction body, so that the traction assembly can be switched to the telescopic mode. On the other hand, when the locking member is not completely disengaged from the matching slot of the first traction body, the linkage member can exert a rightward force on the locking member through the center of the locking member. At the same time, the limiting slot and the right-side matching surface can exert a leftward force on the locking member, and the limiting slot exerts an eccentric force on the locking member. Therefore, under the action of the linkage member and the matching surface of the matching slot of the first traction body, the locking member can be driven to switch from the matching slot to the limiting slot, so that the locking member is switched from the locking position to the disengaging position, and the traction assembly is switched from the fixed-length mode to the telescopic mode.

[0049] According to an embodiment of the present application, one end of the unlocking member is rotatably connected to the handle body, and the other end of the unlocking member is rotatably connected to the first traction body.

[0050] When the traction assembly is in the fixed-length mode, the unlocking member is moved to be unlocked with the machine body directly or indirectly, and the handle body can be flipped relative to the machine body.

[0051] It should be noted that when the handle body is connected with the machine body through the adapter rod, since the machine body is fixedly connected with the adapter rod, the unlocking of the unlocking member with the machine body indirectly means that the unlocking member is unlocked with the machine body through the unlocking of the adapter rod.

[0052] In this application, when the handle body is connected with the machine body through the adapter rod, the unlocking member and the adapter rod can be in the engaged state to make the machine body in the upright state when the wide space to be cleaned is cleaned. When it is needed to clean the low space, the traction assembly is first moved to be in the fixed-length mode through the locking member. At this time, the first traction body can drive the unlocking member to move so that the unlocking member can be unlocked with the adapter rod, and the handle body can be flipped relative to the adapter rod, so that the machine body can be adjusted to be in the lying state for cleaning the low space.

[0053] According to one embodiment of the present application, the folding mechanism further comprises an unlocking elastic member, one end of the unlocking elastic member is connected with the handle body, and the other end of the unlocking elastic member is connected with the unlocking member.

[0054] The folding trigger is used to make the unlocking member be unlocked with the machine body directly or indirectly, and the handle body can be flipped relative to the machine body.

[0055] The unlocking elastic member is used to make the unlocking member be locked with the machine body directly or indirectly.

[0056] Among them, the unlocking member is directly unlocked or locked with the machine body when the handle body is directly connected with the machine body. The indirect unlocking or locking of the unlocking member with the machine body means that the handle body is connected with the machine body through the adapter rod. The unlocking or locking of the unlocking member with the adapter rod realizes the unlocking or locking of the unlocking member with the machine body.

[0057] In this application, the unlocking elastic member can be used to drive the unlocking member to return to the limiting groove. In other words, the unlocking member can be switched from the state of being separated from the limiting groove to the state of being located in the limiting groove through the unlocking elastic member.

[0058] Specifically, when the traction assembly is in the fixed-length mode, the unlocking elastic member can be elastically deformed during the process that the first traction body drives the unlocking member to rotate clockwise to make the unlocking member be separated from the limiting groove. In other words, the first traction body needs to overcome the elastic force of the unlocking elastic member when driving the unlocking member to rotate. Therefore, when the first traction body releases the force acting on the unlocking member, the unlocking elastic member can release the elastic potential energy to drive the unlocking elastic member to return to the limiting groove, so that the unlocking member is locked with the limiting groove, and the handle body cannot be flipped relative to the machine body.

[0059] It should be noted that during the process of the handle body being flipped relative to the machine body, the part of the unlocking member for cooperating with the limiting groove can abut against the outer wall of the adapter rod under the elastic action of the unlocking elastic member. The unlocking elastic member can always apply a restoring force to the unlocking member to the limiting groove.

[0060] According to an embodiment of the present application, the folding trigger member slides relative to the handle body for triggering the unlocking member to be directly or indirectly unlocked with the machine body, and the handle body can be flipped relative to the machine body.

[0061] The folding mechanism further comprises a trigger restoring member, one end of the trigger restoring member is connected with the handle body, and the other end of the trigger restoring member is connected with the folding trigger member, the trigger restoring member is used to drive the folding trigger member to be restored, and the unlocking member is directly or indirectly locked with the machine body.

[0062] In the present application, the user can operate the folding trigger member for making the unlocking member disengage from the limiting groove, so as to realize the flipping of the handle body relative to the machine body. The machine body can be switched to the flat lying state for cleaning the low space. During the process of the unlocking member disengaging from the limiting groove, the trigger restoring member can be deformed. In other words, when the folding trigger member is triggered, the action force of the trigger restoring member needs to be overcome.

[0063] After the cleaning of the low space is completed, the unlocking elastic member and the trigger restoring member can be used together to drive the machine body to be switched from the flat lying state to the upright state or other states. At this time, the handle body can be first adjusted to be flipped relative to the machine body, so that the unlocking member can correspond to the limiting groove. At this time, the unlocking elastic member can drive the unlocking member to be restored to the limiting groove. The unlocking elastic member can drive the traction assembly to be restored. Moreover, the trigger restoring member can release the deformed action force to drive the unlocking member to be restored to the limiting groove.

[0064] According to an embodiment of the present application, the folding mechanism further comprises a second traction body, one end of the second traction body is rotationally connected with the first traction body, and the other end of the second traction body is rotationally connected with the unlocking member.

[0065] In the present application, by setting both ends of the second traction body to be rotationally connected with the first traction body and the unlocking member respectively, the rotational driving of the first traction body to the unlocking member can be realized.

[0066] In the present application, the first traction main body can be a rigid structure to meet the relative sliding of the inner tube and the outer sleeve, and has high motion reliability. By setting the second traction main body as a flexible structure, the force of the axial movement of the first traction main body along the inner tube can be converted into the force for driving the unlocking member to rotate. The structure of the cooperation movement of the first traction main body and the second traction main body has the advantages of stable reliability, simple structure, and small size.

[0067] According to one embodiment of the present application, the telescopic mechanism includes a transmission assembly and a locking pin assembly, the limiting groove is arranged on the transmission assembly, and the locking pin assembly is connected with the transmission assembly. The transmission assembly drives the movement of the locking pin assembly to lock or unlock the length of the inner tube extending out of the outer sleeve.

[0068] When at least part of the locking member is located in the limiting groove, the traction assembly is in the telescopic mode, and the locking pin assembly unlocks the length of the inner tube extending out of the outer sleeve.

[0069] In the present application, since the limiting groove is located on the transmission assembly, the locking member can be switched between the locking position and the disengagement position through the movement of the transmission assembly. When the locking member is located in the cooperation groove, the traction assembly is in the fixed length mode, and the locking member can be used to drive the unlocking member to move to enable the handle main body to be flipped relative to the body. At this time, the locking pin assembly can be in a state of locking the inner tube and the outer sleeve to prevent relative sliding between the inner tube and the outer sleeve. The length of the handle main body is not adjustable. When the locking member is located in the limiting groove, the traction assembly is in the telescopic mode, and the locking member can lock the transmission assembly and the linkage. The transmission assembly and the linkage can move synchronously. At this time, the handle main body cannot be flipped relative to the body. Through the movement of the transmission assembly, the locking pin assembly can unlock the limiting of the inner tube and the outer sleeve. Through the movement of the linkage, the inner tube and the outer sleeve can move relatively to adjust the length of the handle main body.

[0070] It is easy to understand that when the locking member is located in the locking position, the locking pin assembly can lock the inner tube and the outer sleeve, and the inner tube and the outer sleeve will not slide relatively. When the locking member is located in the disengagement position, the locking pin assembly can unlock the inner tube and the outer sleeve, and the length of the inner tube extending out of the outer sleeve is adjustable.

[0071] In a third aspect, the present application provides a cleaning device, which includes a body and the handle assembly in any of the above embodiments. The handle assembly is connected with the body.

[0072] In a fourth aspect, the present application provides a cleaning system, which includes a base or a base station. The cleaning device can be placed on the base or the base station.

[0073] The handle assembly provided by the present application has the beneficial effect that the traction assembly of the folding mechanism can have a fixed length mode and an extension mode. Through the fixed length mode, the handle body can be flipped relative to the machine body, so that the machine body is in a lying state and close to the surface to be cleaned when cleaning low spaces, so as to facilitate the brush assembly to enter the low space for cleaning. Through the extension mode, the inner tube can slide relative to the outer sleeve tube to adjust the length of the handle body, so as to meet the use comfort of users of different heights, and also to adjust the length of the handle body after the handle body is flipped relative to the machine body, so that the user can control the handle body without bending over or squatting when cleaning low spaces.

[0074] Therefore, the embodiments of the present application can meet the use requirements of users of different heights and can be suitable for different application scenarios, thereby improving the user experience.

[0075] In addition to the technical problems solved by the above-described embodiments of the present application, the technical features constituting the technical solutions and the beneficial effects brought by these technical features, other technical problems solved by the handle assembly, the cleaning device and the cleaning system provided by the embodiments of the present application, other technical features included in the technical solutions and the beneficial effects brought by these technical features will be further described in detail in the specific embodiments.

[0110] The specific embodiments of the application have been shown and described in the above-described drawings and text. These drawings and text are not meant to limit the scope of the inventive concept in any way, but merely to illustrate the inventive concept to those skilled in the art by reference to a specific embodiment. DETAILED DESCRIPTION

[0111] The exemplary embodiments will be described in detail herein with reference to the attached drawings. The same numbers are used in different drawings to represent the same or similar elements. The following detailed description is not meant to limit the application in any way. Rather, the following description is meant to provide examplary embodiments of the application in accordance with the application as detailed in the appended claims. It is understood that the described embodiments are merely exemplary of the application and are not meant to limit the application in any way. Based on the embodiments described herein, one of ordinary skill in the art will readily be able to derive other embodiments that are within the scope of the application without having to make any inventive leap.

[0112] The cleaning device provided by the embodiments of the application can be, but is not limited to, a scrubber, an electric broom, an electric mop, a vacuum cleaner. Taking the scrubber as an example, the scrubber is a device for cleaning the ground. The ground can be, but is not limited to, a floor, a tile, a carpet, etc.

[0113] The scrubber generally can be composed of a brush assembly, a rolling brush, a clean water tank, a dirty water tank and the like. The working principle of the scrubber is that through high-speed rotation of a motor, the rolling brush is driven to rotate at high speed, and meanwhile the clean water tank is operated to spray clean water to the rolling brush through a water path. Through high-speed rotation of the rolling brush, dirty water and the like are sucked into the dirty water tank through another water path located behind the rolling brush, so as to complete the cleaning process.

[0114] 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. The brush assembly can clean a surface to be cleaned by rolling on the surface to be cleaned. During the cleaning process of the scrubber, the handle assembly can reach the hands of a user for operation by the user. The user can push and pull the handle assembly to control the cleaning direction of the brush assembly.

[0115] During the cleaning process of the scrubber, an included angle between the machine body and the surface to be cleaned is provided to meet the convenience and labor-saving effect of the user in pushing and pulling the handle assembly. When it is needed to clean a low space, if the included angle between the machine body and the surface to be cleaned is kept during the cleaning process, the height of the machine body will limit the brush assembly from entering the low space, resulting in a sanitary dead angle and affecting the user experience.

[0116] The handle assembly is folded relative to the machine body by the pulling rope structure, so that the included angle between the machine body and the surface to be cleaned can be adjusted when cleaning the low space, and the machine body can be laid flat. The brush assembly can enter the low space to improve the effective cleaning area and avoid the sanitary dead angle.

[0117] However, since the pulling rope cannot be stretched and contracted, the handle assembly cannot realize the stretching and contracting function, and therefore it is difficult to meet the use comfort of a user with a high height. When the machine body is laid flat, the machine body is close to the surface to be cleaned, and the height of the holding end of the handle assembly is reduced, and therefore the user needs to bend over or squat to hold the handle assembly, and the operation process is laborious, which affects the user experience.

[0118] Based on the above technical problems, the applicant improves the structure of the existing handle assembly. In the embodiments of the present application, the traction assembly of the folding mechanism can have a fixed length mode and a stretching and contracting mode. Through the fixed length mode, the handle main body can be flipped relative to the machine body, so that when cleaning the low space, the machine body can be in a laid flat state, and the machine body is close to the surface to be cleaned to facilitate the brush assembly to enter the low space for cleaning. Through the stretching and contracting mode, the inner tube can slide relative to the outer sleeve tube to adjust the length of the handle main body, so that the use comfort of a user with a high height can be met, and the length of the handle main body can also be adjusted after the handle main body is flipped relative to the machine body, so that the user can control the handle main body without bending over or squatting when cleaning the low space.

[0119] Therefore, the embodiments of the present application can meet the use requirements of users of different heights, can be suitable for different application scenarios, and are beneficial to improving user experience.

[0120] It should be noted that in the embodiments of the present application, the cleaning device can clean low spaces or low use scenarios. For example, the bottom of a bed, the bottom of a sofa, the bottom of a table, etc.

[0121] Referring to Figures 1 to 4 , four application scenarios of the cleaning device are exemplarily shown, and the application scenarios of the cleaning device are not limited to the four scenarios.

[0122] Figure 1 A structure schematic view in which the handle assembly 100 and the machine body are in an upright state is exemplarily shown. When the machine body is in the upright state, the machine body and the handle assembly 100 can tend to be collinear. In other words, the included angle between the machine body and the handle assembly 100 is a straight angle. At this time, the machine body can be substantially perpendicular to the surface to be cleaned, for example, the included angle between the machine body and the surface to be cleaned can be between 70° and 90°. The user can comfortably hold the handle assembly 100 to clean the surface to be cleaned in a spacious space. The application scenario in which the machine body is in the upright state can be that the cleaning device is located on a base or a pedestal. For example, the cleaning device can be vertically stood on the base or the pedestal for cleaning or charging the cleaning device. At this time, the handle assembly 100, the machine body and the surface to be cleaned can all be kept vertical to save the space occupied by the cleaning device.

[0123] Figure 2 A structure schematic view in which the handle assembly 100 is telescoped relative to the machine body is exemplarily shown. At this time, the cleaning device can be suitable for users of different heights. By adjusting the length of the inner tube 112 extending out of the outer sleeve 111, the length of the handle assembly 100 is adjusted, so that the height of the holding end of the handle assembly 100 is adjusted, so that users of different heights can comfortably use the cleaning device.

[0124] In some examples, Figure 1 The state of the handle assembly 100 shown can be an initial state, at this time, the handle assembly 100 is not flipped relative to the machine body, and the handle assembly 100 can be in an unelongated state to facilitate transportation and storage of the cleaning device.

[0125] Alternatively, Figure 2The state of the handle assembly 100 shown can be an initial state. At this time, the handle assembly 100 is not flipped relative to the machine body, and the handle assembly 100 is elongated by a distance. For example, the user can adjust the length of the handle assembly 100 according to the height in the initial state, so that it is not necessary to adjust the length of the handle assembly 100 every time the same user performs subsequent cleaning operations. The user only needs to adjust the folding of the handle assembly 100 relative to the machine body when encountering different low spaces.

[0126] It should be noted that the user can set the initial state of the handle assembly 100 according to the height and application scenario, which is not limited in the embodiments of the present application.

[0127] Figure 3 An exemplary structure diagram of the folding of the handle assembly 100 relative to the machine body is shown. At this time, the cleaning device can be used to clean the to-be-cleaned surface in the low space. The machine body and the to-be-cleaned surface can tend to be horizontal, so that the machine body can be in a lying state, thereby facilitating the brush assembly to enter the low space for cleaning.

[0128] It should be noted that when the machine body is in the lying state, the machine body and the to-be-cleaned surface can be substantially parallel. For example, the included angle between the machine body and the to-be-cleaned surface can be between 0° and 10°.

[0129] Figure 4 An exemplary structure diagram of the folding and stretching of the handle assembly 100 relative to the machine body is shown. For example, when cleaning the to-be-cleaned surface of the low space, the handle assembly 100 is folded relative to the machine body. The height of the holding end of the handle assembly 100 relative to the to-be-cleaned surface is lowered, and the user needs to bend down to hold the handle assembly 100. At this time, the handle assembly 100 can be stretched to increase the height of the holding end of the handle assembly 100 relative to the to-be-cleaned surface, so that the user can clean the to-be-cleaned surface of the low space without bending down.

[0130] The handle assembly 100, the cleaning device and the cleaning system provided by the present application will be described below with reference to the accompanying drawings and in conjunction with specific embodiments.

[0131] Referring to Figures 5 to 11 As shown, the handle assembly 100 of the embodiments of the present application is applied to a cleaning device. The handle assembly 100 can include a handle body 110, a folding mechanism 120 and a locking member 130.

[0132] The handle body 110 is directly or indirectly connected to the machine body of the cleaning device. The handle body 110 can be flipped relative to the machine body. The handle body 110 includes an outer sleeve 111 and an inner tube 112. The inner tube 112 is slidably connected to the outer sleeve 111.

[0133] The folding mechanism 120 is located in the handle body 110. The folding mechanism 120 comprises a folding trigger 121, a traction assembly, and an unlocking piece 123, the folding trigger 121 drives the unlocking piece 123 through the traction assembly to overturn the handle body 110 relative to the machine body; the traction assembly has a fixed-length mode and a telescopic mode.

[0134] The locking piece 130 moves in the handle body 110 to realize the switching of the fixed-length mode and the telescopic mode of the traction assembly. Among them, when the traction assembly is in the fixed-length mode, the handle body 110 can be overturned relative to the machine body. When the traction assembly is in the telescopic mode, the inner tube 112 can slide relative to the outer sleeve 111 to realize the telescoping of the handle body 110.

[0135] 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, so that the overall length of the traction assembly can remain unchanged during movement. The telescopic mode of the traction assembly refers to the relative movement between the internal structures of the traction assembly, so that the overall length of the traction assembly changes. The overall length of the traction assembly can be extended or shortened.

[0136] In the embodiments of the present application, by setting the locking piece 130, the traction assembly can have a fixed-length mode and a telescopic mode, the overturning of the handle body 110 relative to the machine body can be realized, and the length adjustment of the handle body 110 can also be realized, which can meet the use comfort of users of different heights and different application scenarios.

[0137] When the traction assembly is in the fixed-length mode, the handle body 110 can be overturned relative to the machine body, so that the machine body can be in a flat lying state, and the brush assembly can be deep into a low space to clean the low space.

[0138] When the traction assembly is in the telescopic mode, the inner tube 112 of the handle body 110 can slide relative to the outer sleeve 111. By adjusting the length of the inner tube 112 extending out of the outer sleeve 111, the length of the handle assembly 100 can be adjusted, so as to meet the use requirements of users of different heights and different application scenarios. For example, when the machine body is in an upright state, for users with small height, the length of the inner tube 112 extending out of the outer sleeve 111 can be adjusted to be small, or the inner tube 112 does not extend out of the outer sleeve 111. For users with high height, the length of the inner tube 112 extending out of the outer sleeve 111 can be adjusted to be long, so as to increase the overall length of the handle assembly 100, thereby increasing the height of the gripping end of the handle assembly 100, and improving the use comfort of users with high height.

[0139] When the machine body is in the lying state, the height of the holding end of the handle assembly 100 is lowered. Especially for users with a higher height, the inner tube 112 can be adjusted to extend out of the outer sleeve 111 by a longer size, so that the height of the holding end of the handle assembly 100 is increased, so that the user can operate the handle assembly 100 without bending or squatting, which is beneficial to improve the use comfort of the cleaning equipment when cleaning low space.

[0140] In some examples, the handle body 110 is directly or indirectly connected with the machine body of the cleaning equipment. Specifically, the handle body 110 can be directly rotatably connected with the machine body, or the handle body 110 can be connected with the machine body through the adapter rod 160. The connection manner is not limited in the embodiments of the present application.

[0141] For example, referring to FIG. 1, when the handle body 110 is connected with the machine body through the adapter rod 160, the handle body 110 and the adapter rod 160 can be rotatably connected through the rotation shaft 180. The adapter rod 160 and the machine body can be fixedly connected through the clamping manner, but the connection manner is not limited. Figures 1 to 4

[0142] In some examples, the holding end of the handle assembly 100 can be provided with an operation key. The operation key can be a physical key or a touch key, and the connection manner is not limited in the embodiments of the present application. A control module can be arranged in the brush assembly to control the cleaning mode of the cleaning equipment. The operation key and the control module can be electrically connected through the conductive cable 190, so that the brush assembly can be controlled to be in different cleaning modes when the user triggers the operation key.

[0143] In some examples, the handle assembly 100 is provided with a space for accommodating the conductive cable 190. The end of the handle assembly 100 for connecting with the machine body can be provided with a terminal. The terminal is electrically connected with the conductive cable 190. The terminal can be plugged into the machine body, so that the conductive cable 190 is electrically connected with the control module through the terminal.

[0144] In some examples, when the cleaning equipment walks on the horizontal surface to be cleaned, the handle body 110 can be flipped in the vertical plane relative to the machine body. The axial direction of the rotation shaft 180 is perpendicular to the vertical plane.

[0145] In some examples, the outer sleeve 111 can be sleeved outside at least part of the inner tube 112. Since the inner tube 112 is slidably connected with the outer sleeve 111, the overall length of the handle body 110 is larger when the inner tube 112 extends out of the outer sleeve 111 by a larger size. The axial direction of the inner tube 112 and the axial direction of the outer sleeve 111 can be the same. The sliding direction of the inner tube 112 and the outer sleeve 111 can be the same as the axial direction of the inner tube 112.

[0146] ​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, the external force can be applied to the folding trigger 121 while the handle body 110 is held by one hand, so that the handle body 110 can be flipped relative to the machine body by one-handed operation to adjust the switching of the machine body between the lying state and the upright state. In this process, two-handed operation can not be required, and the operation is quick and convenient, which is conducive to improving the user experience.

[0147] In some examples, the outer sleeve 111 and the inner tube 112 can be, but are not limited to, circular tubes, square tubes, etc.

[0148] The present application provides another handle assembly 100. The handle assembly 100 can include a handle body 110, a folding mechanism 120, and a locking member 130.

[0149] The handle body 110 is directly or indirectly connected to the machine body of the cleaning device. The handle body 110 can be flipped relative to the machine body. The handle body 110 includes an outer sleeve 111 and an inner tube 112, and the inner tube 112 is slidably connected to the outer sleeve 111.

[0150] The folding mechanism 120 is located in the handle body 110. The folding mechanism 120 can 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 machine body; the traction assembly has a fixed-length mode and an extension mode.

[0151] The locking member 130 moves in 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 the 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 the extension mode, and the inner tube 112 can slide relative to the outer sleeve 111 to achieve the extension of the handle body 110.

[0152] In the present application, the locking member 130 is used to switch the traction assembly between the fixed-length mode and the extension 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 extension mode.

[0153] 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.

[0154] 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.

[0155] 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.

[0156] 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.

[0157] 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.

[0158] 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.

[0159] The locking member 130 locks the first traction body 1221 and the linkage member 1222 to synchronize the movement of the first traction body 1221 and the linkage member 1222, and the traction assembly is in the fixed-length mode. The locking member 130 unlocks the first traction body 1221 and the linkage member 1222 to enable the first traction body 1221 to slide relative to the linkage member 1222. The traction assembly is in the telescopic mode.

[0160] In the embodiments of the present application, the first traction body 1221 and the linkage member 1222 have two movement states to correspond to the fixed-length mode and the telescopic mode of the traction assembly, respectively. When the locking member 130 is in the locking position, the first traction body 1221 and the linkage member 1222 are locked by the locking member 130. The first traction body 1221 and the linkage member 1222 can move synchronously, so that the overall length of the traction assembly remains fixed during the movement. In other words, the traction assembly is in the fixed-length mode. Therefore, the first traction body 1221 and the linkage member 1222 can be used together to drive the unlocking member 123 to move, so as to realize the rotation of the handle body 110 relative to the machine body.

[0161] When the locking member 130 is in the disengaging position, the locking member 130 can unlock the first traction body 1221 and the linkage member 1222. The first traction body 1221 and the linkage member 1222 can slide relative to each other. One of the first traction body 1221 and the linkage member 1222 can be used to enable the inner tube 112 to slide relative to the outer sleeve 111. Since the first traction body 1221 is connected to the unlocking member 123, the movement of the first traction body 1221 will cause the unlocking member 123 to move and affect the relative position of the handle body 110 and the machine body. Therefore, the inner tube 112 and the outer sleeve 111 can slide relative to each other by the movement of the linkage member 1222. In other words, the first traction body 1221 can remain in a stationary state relative to the handle body 110, and the linkage member 1222 slides relative to the first traction body 1221 to enable the inner tube 112 and the outer sleeve 111 to slide relative to each other.

[0162] In some examples, the linkage member 1222 can be sleeved on the outside of at least part of the first traction body 1221. One end of the first traction body 1221 can extend outside the linkage member 1222 to drive the unlocking member 123 to move.

[0163] In some examples, the direction of the relative sliding of the first traction body 1221 and the linkage member 1222 can be the axial movement of the inner tube 112. In other words, the direction of the relative sliding of the first traction body 1221 and the linkage member 1222 is the same as the direction of the relative sliding of the inner tube 112 and the outer sleeve 111, so that the movement of the linkage member 1222 can directly act on the inner tube 112, reducing the complexity of the internal structure of the handle assembly 100.

[0164] In some possible implementations, referring to Figure 8 and Figure 9 illustrated, at least part of the first traction body 1221 of the embodiment of the present application is located inside the linkage 1222. The first traction body 1221 is provided with a matching groove 1221a capable of accommodating at least part of the locking member 130. The linkage 1222 is provided with a locking hole 122a capable of being penetrated by the locking member 130.

[0165] When the traction assembly is in the fixed-length mode, the matching groove 1221a and the locking hole 122a can correspond to each other. The locking member 130 is located in the matching groove 1221a and the locking hole 122a. When the traction assembly is in the telescopic mode, the matching groove 1221a and the locking hole 122a can be arranged staggered. The locking member 130 is separated from the first traction body 1221.

[0166] In the embodiment of the present application, the locking member 130 can be switched between the locking position and the disengagement position through the cooperation of the locking member 130, the matching groove 1221a and the locking hole 122a. In this way, the switching of the traction assembly between the fixed-length mode and the telescopic mode can be realized through a simple structure.

[0167] Specifically, the locking member 130 can move in the inner tube 112. When the matching groove 1221a and the locking hole 122a correspond to each other, at least part of the locking member 130 can be located in the matching groove 1221a and the locking groove. The locking member 130 can lock the first traction body 1221 and the linkage 1222 to limit the relative sliding between the first traction body 1221 and the linkage 1222, so that the first traction body 1221 and the linkage 1222 can move synchronously. The overall length of the traction assembly remains fixed, and the traction assembly is in the fixed-length mode. At this time, the unlocking member 123 can be driven to move by the first traction body 1221 to make the handle body 110 flip relative to the machine body.

[0168] When the matching groove 1221a and the locking hole 122a are arranged staggered along the movement direction of the first traction body 1221 relative to the linkage 1222, the locking member 130 can be disengaged from the matching groove 1221a. In other words, the locking member 130 is not in contact with 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 1222, and the locking member 130 is in contact with the linkage 1222. The locking member 130 and the linkage 1222 can move synchronously to make the linkage 1222 slide relative to the first traction body 1221.

[0169] In some examples, the relative movement direction of the first traction body 1221 and the linkage 1222 is the axis of the inner tube 112. When the locking member 130 is disengaged from the matching groove 1221a to be located in the disengagement position, the traction assembly is in the telescopic mode. In combination withFigure 8 and Figure 9 When the linkage 1222 moves to the right (away from the body), the overall length of the traction assembly can increase to increase the overall length of the handle body 110. When the length of the handle body 110 needs to be reduced, the linkage 1222 can be moved to the left (towards the body) to reduce the overall length of the traction assembly, thereby meeting the comfort of users of different heights and different application scenarios.

[0170] 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 during the movement of the linkage 1222, so as not to affect the movement state of the unlocking member 123, and thus the handle body 110 will not be flipped relative to the body.

[0171] In some examples, the surfaces of the locking member 130 and the mating groove 1221a that cooperate with each other can be curved surfaces to improve the smoothness of the switching of the locking member 130 between the locked position and the disengaged position. Also, the driving force required to drive the movement of the locking member 130 can be reduced, reducing the possibility of requiring a large driving force during the movement of the locking member 130.

[0172] In some examples, when the locking member 130 is in the locked position, the cross-sectional shape of the locking member 130 can be the same as the cross-sectional shape of the mating groove 1221a. The cross-section can refer to Figure 8 the horizontal plane in the direction shown.

[0173] For example, the locking member 130 can be a cylindrical structure. The mating groove 1221a can be a semicylindrical groove structure. The semicylindrical groove structure refers to an incomplete cylindrical structure.

[0174] In some realizable ways, referring to Figures 8 to 11 the handle assembly 100 of the present application can further include a telescopic mechanism 140. At least part of the telescopic mechanism 140 moves within the inner tube 112. The telescopic mechanism 140 can be provided with a limiting groove 140a capable of accommodating at least part 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.

[0175] In the present application, by providing the limiting groove 140a capable of accommodating at least part of the locking member 130 on the telescopic mechanism 140, 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.

[0176] When the limiting slot 140a on the telescopic mechanism 140 corresponds to the locking hole 122a on the linkage 1222, the locking member 130 can be disengaged from the matching slot 1221a and fall into the matching slot 1221a through the locking hole 122a on the linkage 1222. At this time, the linkage 1222 can move relative to the first traction main body 1221 to make the traction assembly in the telescopic mode.

[0177] When the traction assembly is in the telescopic mode, the locking member 130 can be located in the locking hole 122a and the limiting slot 140a, so that the linkage 1222 and the telescopic mechanism 140 can operate synchronously. The linkage 1222 moves along the axial direction of the inner tube 112 to adjust the distance of the inner tube 112 extending out of the outer sleeve tube 111, so as to adjust the overall length of the handle main body 110.

[0178] Therefore, the linkage 1222 can realize the associated movement of the folding mechanism 120 and the telescopic mechanism 140, and the folding mechanism 120 and the telescopic mechanism 140 can not interfere with each other. When the locking member 130 is located in the locking position, the traction assembly is in the fixed-length mode, and the linkage 1222 can be used together with the first traction main body 1221 to drive the unlocking member 123 to move, so as to realize the overturning of the handle main body 110 relative to the machine body. When the locking member 130 is located in the disengaged position, the traction assembly is in the telescopic mode, the linkage 1222 can move relative to the first traction main body 1221, and the linkage 1222 can move synchronously with the telescopic mechanism 140 to realize the adjustment of the overall length of the handle main body 110.

[0179] In some examples, the surfaces of the limiting slot 140a and the locking member 130 that match with each other can be arc surfaces, so as to improve the smoothness of the switching of the locking member 130 between the locking position and the disengaged position. For example, the locking member 130 can be a cylindrical structure. The limiting slot 140a can be a semicylindrical groove structure.

[0180] In some examples, the shape of the locking hole 122a can match the shape of the locking member 130. During the switching of the locking member 130 between the locking position and the disengaged position, the locking member 130 can remain located in the locking hole 122a.

[0181] In some examples, the linkage 1222 can be but is not limited to a sleeve structure. For example, the linkage 1222 can be a square sleeve. Since the linkage 1222 is sleeved on the outside of at least part of the first traction main body 1221, the first traction main body 1221 can be a square rod structure.

[0182] In some realizable modes, referring to Figure 8As shown, the locking hole 122a of the embodiment of the present application can be arranged on the side wall of the linkage 1222 close to 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 in the extension direction of the side wall.

[0183] In the embodiment of the present application, when the telescopic mechanism 140 moves to make the limiting groove 140a correspond to the locking hole 122a and the matching groove 1221a during the switching of the locking member 130 from the locking position to the disengagement position, by arranging the side wall of the linkage 1222 to be aligned with the center of the locking member 130 in the extension direction of the side wall, the switching of the locking member 130 from the locking position to the disengagement position can be facilitated.

[0184] Specifically, referring to the direction shown in Figures 8 to 11 When the telescopic mechanism 140 moves to make the limiting groove 140a correspond to the locking hole 122a and the matching groove 1221a, on the one hand, the locking member 130 can fall into the limiting groove 140a under the action of its own gravity. The locking member 130 can be disengaged from the matching groove 1221a of the first traction main body 1221, so that the traction assembly can be switched to the telescopic mode. On the other hand, when the locking member 130 is not completely disengaged from the matching groove 1221a of the first traction main body 1221, the linkage 1222 can exert a rightward force on the locking member 130 through the center of the locking member 130. At the same time, the limiting groove 140a and the right-side matching surface can exert a leftward force on the locking member 130, and the limiting groove 140a exerts an eccentric force on the locking member 130. Therefore, under the action of the linkage 1222 and the matching surface of the matching groove 1221a of the first traction main body 1221, the locking member 130 can be driven to switch from the matching groove 1221a to the limiting groove 140a, so that the locking member 130 is switched from the locking position to the disengagement position, and the traction assembly is switched from the fixed-length mode to the telescopic mode.

[0185] In some examples, the matching groove 1221a can be provided with a guiding matching surface. The matching surface on the matching groove 1221a can be a rounded or chamfered structure.

[0186] In some examples, the first traction main body 1221 and the telescopic mechanism 140 can be arranged side by side in the inner tube 112. Moreover, the telescopic mechanism 140 can be located on the side of the first traction main body 1221 close to the surface to be cleaned, for example Figure 11 In the embodiment of the present application, the telescopic mechanism 140 is located below the first traction main body 1221, so that when the locking member 130 is switched from the locking position to the disengagement position, the locking member 130 can fall into the limiting groove 140a under the action of its own gravity.

[0187] When the locking member 130 is switched from the disengagement position to the locking position, referring to Figures 8 to 11In the shown direction, first make the limiting groove 140a of the telescopic mechanism 140 correspond to the limiting groove 140a of the first traction main body 1221, and then the telescopic mechanism 140 can reset to the right. At this time, the telescopic mechanism 140 can exert a rightward force on the locking piece 130. The matching surface of the limiting groove 140a on the left side of the locking piece 130 can exert an obliquely upward force on the locking piece 130 to extrude the locking piece 130 from the limiting groove 140a into the matching groove 1221a, so that the locking piece 130 is switched from the disengagement position to the locking position, and the traction assembly is switched from the telescopic mode to the fixed-length mode.

[0188] In some examples, a guiding matching surface can be arranged on the limiting groove 140a. The matching surface on the limiting groove 140a can be a rounded or chamfered structure.

[0189] In some examples, the matching groove 1221a can be arranged on the surface of the first traction main body 1221 facing the telescopic mechanism 140. The locking hole 122a can be arranged on the inner wall of the linkage 1222 close to the matching groove 1221a. The limiting groove 140a can be arranged on the surface of the telescopic mechanism 140 facing the folding mechanism 120.

[0190] In some realizable modes, referring to Figure 8 and Figure 9 As shown, one end of the unlocking piece 123 of the embodiment of the application is rotatably connected to the handle main body 110, and the other end of the unlocking piece 123 is rotatably connected to the first traction main body 1221. When the traction assembly is in the fixed-length mode, the unlocking piece 123 moves to directly or indirectly unlock the machine body, and the handle main body 110 can be flipped relative to the machine body.

[0191] It should be noted that when the handle main body 110 is connected to the machine body through the adapter rod 160, since the machine body is fixedly connected to the adapter rod 160, the indirect unlocking between the unlocking piece 123 and the machine body means that the unlocking piece 123 is unlocked by unlocking the adapter rod 160 to realize the unlocking between the unlocking piece 123 and the machine body.

[0192] In the embodiment of the application, taking the example that the handle main body 110 is connected to the machine body through the adapter rod 160, when cleaning the cleaning surface of a spacious space, the unlocking piece 123 and the adapter rod 160 can be in the engaged state to make the machine body in the upright state. When it is necessary to clean a low space, first move the locking piece 130 to make the traction assembly in the fixed-length mode. At this time, the first traction main body 1221 can drive the unlocking piece 123 to move, so that the unlocking piece 123 can be unlocked with the adapter rod 160, and the handle main body 110 can be flipped relative to the adapter rod 160, so that the machine body can be adjusted to be in the lying state for cleaning the low space.

[0193] ​In some examples, the adapter rod 160 can be detachably connected to the machine body. The handle assembly 100 can be detachable from the machine body through the adapter rod 160 to facilitate transportation or storage of the cleaning device.

[0194] In some realizable manners, when the handle body 110 is connected to the machine body through the adapter rod 160, a locking groove can be arranged on the adapter rod 160. When the partial 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 is relatively fixed with the adapter rod 160. The handle body 110 cannot be flipped relative to the machine body.

[0195] Specifically, referring to the direction shown in Figure 9 , the traction assembly is in the fixed-length mode, and the clockwise rotation of the first traction body 1221 to drive the unlocking member 123 can make the unlocking member 123 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, and thus the handle body 110 can be flipped relative to the adapter rod 160.

[0196] In some realizable manners, the folding mechanism 120 of the embodiments of the present application can further include an unlocking elastic member. One end of the unlocking elastic member is connected to the handle body 110, and the other end of the unlocking elastic member is connected to the unlocking member 123. The folding trigger 121 is used to directly or indirectly unlock the unlocking member 123 from the machine body, so that the handle body 110 can be flipped relative to the machine body. The unlocking elastic member is used to directly or indirectly lock the unlocking member 123 with the machine body.

[0197] Herein, the direct unlocking or locking of the unlocking member 123 with the machine body means that when the handle body 110 is directly connected to the machine body, the unlocking member 123 can be directly unlocked or locked with the machine body. The indirect unlocking or locking of the unlocking member 123 with the machine body means that the handle body 110 is connected to the machine body through the adapter rod 160. The unlocking member 123 is unlocked or locked with the machine body through the unlocking or locking with the adapter rod 160.

[0198] In the embodiments of the present application, the unlocking elastic member can be used to drive the unlocking member 123 to return to the limiting groove 160a. In other words, through the unlocking elastic member, the unlocking member 123 can be switched from the state of disengaging from the limiting groove 160a to the state of being located in the limiting groove 160a.

[0199] Specifically, the traction assembly is in the fixed-length mode, and in the process that the first traction body 1221 drives the unlocking piece 123 to rotate clockwise to make the unlocking piece 123 disengage from the limiting groove 160a, the unlocking elastic piece can be elastically deformed. In other words, the first traction body 1221 needs to overcome the elastic force of the unlocking elastic piece when driving the unlocking piece 123 to rotate. Therefore, when the first traction body 1221 releases the force acting on the unlocking piece 123, the unlocking elastic piece can release the elastic potential energy to drive the unlocking elastic piece to reset into the limiting groove 160a, so that the unlocking piece 123 is locked with the limiting groove 160a, and the handle body 110 cannot be flipped relative to the machine body.

[0200] It should be noted that in the process that the handle body 110 is flipped relative to the machine body, the part of the unlocking piece 123 for cooperating with the limiting groove 160a can abut against the outer wall of the adapter rod 160 under the elastic action of the unlocking elastic piece. The unlocking elastic piece can always exert a force on the unlocking piece 123 to reset into the limiting groove 160a.

[0201] In some examples, the unlocking elastic piece can be, but is not limited to, a torsion spring.

[0202] In some implementable manners, the folding trigger 121 slides relative to the handle body 110 to trigger the unlocking piece 123 to directly or indirectly unlock with the machine body, and the handle body 110 can be flipped relative to the machine body.

[0203] The folding mechanism 120 can further include a trigger reset piece 124. One end of the trigger reset piece 124 is connected with the handle body 110. The other end of the trigger reset piece 124 is connected with the folding trigger 121. The trigger reset piece 124 is used to drive the folding trigger 121 to reset, and the unlocking piece 123 can be directly or indirectly locked with the machine body.

[0204] In the embodiments of the present application, the user can operate the folding trigger 121 to make the unlocking piece 123 disengage from the limiting groove 160a, so as to flip the handle body 110 relative to the machine body. The machine body can be switched to the flat-laying state to clean low spaces. In the process that the unlocking piece 123 disengages from the limiting groove 160a, the trigger reset piece 124 can be deformed. In other words, when the folding trigger 121 is triggered, the force of the trigger reset piece 124 needs to be overcome.

[0205] 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.

[0206] 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.

[0207] 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.

[0208] 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.

[0209] 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.

[0210] 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.

[0211] 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.

[0212] When the at least partial locking member 130 is located in the matching groove 1221a, the traction assembly is in the fixed length mode. The locking pin assembly 142 can lock the length of the inner tube 112 extending out of the outer sleeve 111. When the at least partial locking member 130 is located in the limiting groove 140a, the traction assembly is in the telescopic mode, and the locking pin assembly 142 can unlock the length of the inner tube 112 extending out of the outer sleeve 111.

[0213] In the embodiments of the present application, the limiting groove 140a is located on the transmission assembly 141, and the movement of the transmission assembly 141 can switch the locking member 130 between the locking position and the disengaging position. When the locking member 130 is located in the matching groove 1221a, the traction assembly is in the fixed length mode, and the locking member 130 can be used to drive the unlocking member 123 to move so that the handle body 110 can be flipped relative to the machine body. At this time, the locking pin assembly 142 can be in the state of locking the inner tube 112 and the outer sleeve 111, so that the inner tube 112 and the outer sleeve 111 cannot slide relative to each other. The length of the handle body 110 cannot be adjusted. When the locking member 130 is located in the limiting groove 140a, the traction assembly is in the telescopic mode, and the locking member 130 can lock the transmission assembly 141 and the linkage 1222, and the transmission assembly 141 and the linkage 1222 can move synchronously. At this time, the handle body 110 cannot be flipped relative to the machine body. The movement of the transmission assembly 141 can unlock the inner tube 112 and the outer sleeve 111 by the locking pin assembly 142, and the movement of the linkage 1222 can make the inner tube 112 and the outer sleeve 111 move relative to each other, so as to adjust the length of the handle body 110.

[0214] It is easy to understand that when the locking member 130 is located in the locking position, the locking pin assembly 142 can lock the inner tube 112 and the outer sleeve 111, and the inner tube 112 and the outer sleeve 111 cannot slide relative to each other. When the locking member 130 is located in the disengaging position, the locking pin assembly 142 can unlock the inner tube 112 and the outer sleeve 111, and the length of the inner tube 112 extending out of the outer sleeve 111 can be adjusted.

[0215] In some examples, the inner tube 112 can be provided with an escape hole 112a. The outer sleeve 111 can be provided with a plurality of gear adjustment holes 111a. When the locking pin assembly 142 corresponds to the escape hole 112a and the gear adjustment hole 111a, the locking pin assembly 142 can be inserted into the escape hole 112a and the gear adjustment hole 111a, so that the inner tube 112 and the outer sleeve 111 are locked relative to each other. No relative sliding occurs between the inner tube 112 and the outer sleeve 111. When the locking pin assembly 142 does not correspond to the gear adjustment hole 111a, the locking pin assembly 142 does not hinder the movement of the inner tube 112 relative to the outer sleeve 111, and the locking pin assembly 142 can move in the inner tube 112. When the length of the inner tube 112 extending out of the outer sleeve 111 can meet the comfort of use, the locking pin assembly 142 can be inserted into the corresponding gear adjustment hole 111a.

[0216] In some realizable modes, the telescopic mechanism 140 can further include a telescopic trigger 143. The telescopic trigger 143 can be located at the end of the handle body 110 away from the machine 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 length of the inner tube 112 extending out of the outer sleeve 111.

[0217] In the embodiments of the present application, when it is necessary to adjust the length of the handle body 110, the telescopic trigger 143 can be used to drive the telescopic mechanism 140 to move, so that the locking member 130 is switched to the disengagement position, and the traction assembly can be in the telescopic mode, so that the synchronous movement of the linkage 1222 and the transmission assembly 141 causes the locking pin assembly 142 to adjust the length of the inner tube 112 extending out of the outer sleeve 111.

[0218] The embodiments of the present application also provide a cleaning device, which can include a machine body and the handle assembly 100 in any of the above embodiments. The handle assembly 100 is connected to the machine body.

[0219] In some examples, the cleaning device can further include a clean water tank and a dirty water tank. The clean water tank and the dirty water tank can be arranged on the brush assembly or on the machine body. Alternatively, one of the clean water tank and the dirty water tank can be arranged on the brush assembly, and the other can be arranged on the machine body. The embodiments of the present application are not limited in this regard.

[0220] The embodiments of the present application also provide a cleaning system. The cleaning system can include a base or a station. The cleaning device can be placed on the base or the station.

[0221] In some examples, the base can be used to wash the roller brush and dry the roller brush, so as to avoid the generation of odor or bacteria due to the long time of the roller brush in a wet state.

[0222] In some examples, the base station can have a charging function. When the cleaning device is placed on the base station, the base station can be charged, and the water can be automatically supplied and discharged. The base and the base station can be a split structure, or the base and the base station can be an integrated structure, which is not limited in the embodiments of the present application.

[0223] Referring to Figures 8 to 11 As shown in the drawings, the handle assembly 100 of the embodiments of the present application is applied to a cleaning device. The handle assembly 100 can include a handle body 110, a locking piece 130, a folding mechanism 120, and a telescopic mechanism 140.

[0224] The handle body 110 is directly or indirectly connected to the body of the cleaning device. The handle body 110 can be flipped relative to the body. The handle body 110 includes an outer sleeve 111 and an inner tube 112. The inner tube 112 is slidably connected to the outer sleeve 111. The locking piece 130 can move in the handle body 110.

[0225] The folding mechanism 120 is provided on the handle body 110. The folding mechanism 120 is provided with a matching groove 1221a capable of accommodating at least part of the locking piece 130. The folding mechanism 120 is used to achieve the clamping or flipping of the handle body 110 relative to the body when the locking piece 130 is located in the matching groove 1221a.

[0226] 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 sleeve 111. The transmission assembly 141 is provided with a limiting groove 140a capable of accommodating at least part of the locking piece 130. The transmission assembly 141 moves along the length direction of the outer sleeve 111 to drive the locking piece 130 to switch in the matching groove 1221a or the limiting groove 140a.

[0227] When the locking piece 130 enters the limiting groove 140a, the inner tube 112 and the outer sleeve 111 are unlocked by the locking pin assembly 142, so that the inner tube 112 can slide relative to the outer sleeve 111.

[0228] It should be noted that the embodiments of the present application take the example of the handle body 110 being connected to the body of the cleaning device through the adapter rod 160 for description.

[0229] In the embodiments of the present application, the folding mechanism 120 and the telescopic mechanism 140 can realize the folding of the handle body 110 relative to the machine body, and also realize the telescopic adjustment of the handle body 110. Therefore, the handle body 110 can be folded relative to the machine body, so that the machine body is in a flat state to be suitable for cleaning in a low space. In addition, the handle body 110 can be telescoped to meet the comfort of use of users with different heights. In addition, the length of the handle body 110 can be adjusted by the telescopic adjustment of the handle body 110 after the folding of the handle body 110 relative to the machine body. Alternatively, the length of the handle body 110 can be adjusted by the telescopic adjustment of the handle body 110 first, and then the handle body 110 is folded relative to the machine body. Therefore, the handle assembly 100 of the embodiments of the present application can meet the comfort of use of users with different heights and different application scenarios.

[0230] Specifically, the folding mechanism 120 can realize the clamping or folding of the handle body 110 relative to the machine body. When the handle body 110 is clamped with the machine body, the handle body 110 and the machine body will not produce a folding movement. When the handle body 110 can be folded relative to the machine body, the machine body can be in a flat state to be suitable for cleaning in a low space.

[0231] The telescopic mechanism 140 can realize the telescopic adjustment of the handle body 110. When the inner tube 112 and the outer sleeve 111 can produce relative sliding, the telescopic adjustment of the handle body 110 can be realized by the relative sliding of the inner tube 112 and the outer sleeve 111, so as to realize the length adjustment of the handle body 110. When the inner tube 112 and the outer sleeve 111 are locked, the inner tube 112 and the outer sleeve 111 are relatively fixed, and the length of the handle body 110 is fixed.

[0232] The locking pin assembly 142 can be used to control the relative sliding or relative fixation between the inner tube 112 and the outer sleeve 111.

[0233] In addition, by arranging the locking piece 130, the folding movement of the handle body 110 relative to the machine body and the telescopic movement of the handle body 110 can be performed respectively by the position of the locking piece 130. In other words, when the handle body 110 is folded relative to the machine body, the inner tube 112 and the outer sleeve 111 can be relatively fixed, and the length of the handle body 110 cannot be adjusted. When the inner tube 112 and the outer sleeve 111 relatively slide, the angle of the handle body 110 relative to the machine body can remain fixed, and the angle of the handle body 110 relative to the machine body cannot be adjusted.

[0234] In this way, the user can conveniently control the handle body 110, and the flipping movement and the telescopic movement of the handle body 110 cannot be simultaneously performed, so that the handle body 110 is difficult to control. In addition, when the flipping movement and the telescopic movement are simultaneously performed, the flipping movement and the telescopic movement interfere with each other, and faults are prone to occur, thereby affecting the user experience.

[0235] In some possible implementation manners, referring to FIGS. 1 and 2, the at least partial locking piece 130 is located in the matching groove 1221a, the handle body 110 can be flipped relative to the machine body, and the lock pin assembly 142 locks the inner tube 112 and the outer sleeve 111. The at least partial locking piece 130 is located in the limiting groove 140a, the flipping movement of the handle body 110 relative to the machine body is locked, and the lock pin assembly 142 unlocks the inner tube 112 and the outer sleeve 111. Figure 8 Figure 9 In some possible implementation manners, referring to FIGS. 1 and 2, the at least partial locking piece 130 is located in the matching groove 1221a, the handle body 110 can be flipped relative to the machine body, and the lock pin assembly 142 locks the inner tube 112 and the outer sleeve 111. The at least partial locking piece 130 is located in the limiting groove 140a, the flipping movement of the handle body 110 relative to the machine body is locked, and the lock pin assembly 142 unlocks the inner tube 112 and the outer sleeve 111.

[0236] In the embodiment, the movement of the locking piece 130 in the handle body 110 cooperates with the lock pin assembly 142, so that the flipping movement and the telescopic movement of the handle body 110 can be performed step by step.

[0237] Specifically, when the at least partial locking piece 130 is located in the matching groove 1221a, the folding mechanism 120 can move, so that the handle body 110 can be clamped or flipped relative to the machine body. At this time, the inner tube 112 and the outer sleeve 111 are locked by the lock pin assembly 142, so that the inner tube 112 and the outer sleeve 111 are relatively fixed during the flipping of the handle body 110.

[0238] When the at least partial locking piece 130 is located in the limiting groove 140a, the inner tube 112 and the outer sleeve 111 can be unlocked by the lock 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 sleeve 111. At this time, the position of the locking piece 130 can make the handle body 110 unable to flip relative to the machine body.

[0239] Therefore, the length of the handle body 110 can be adjusted after the angle of the handle body 110 relative to the machine body is adjusted, or the handle body 110 can be flipped relative to the machine body after the distance of the relative sliding of the inner tube 112 and the outer sleeve 111 is adjusted. In the embodiment, the adjustment sequence is not limited.

[0240] In some possible implementation manners, referring to FIGS. 1 and 2, the transmission assembly 141 moves forward or reversely in the inner tube 112, to drive the locking piece 130 to switch in the limiting groove 140a and the matching groove 1221a. Figures 8 to 11

[0241] ​​In the embodiments of the present application, the driving assembly 141 can be used to drive the locking piece 130 to switch in the limiting groove 140a and the matching groove 1221a by changing the moving direction of the driving assembly 141 in the inner tube 112, so as to realize the switching of the folding motion and the telescopic motion of the handle body 110.

[0242] In some examples, the driving assembly 141 can move along the length direction of the outer sleeve tube 111. The length direction of the outer sleeve tube 111 can be the same direction as the axial direction of the outer sleeve tube 111.

[0243] In some examples, in the initial state of the handle assembly 100, the included angle between the handle body 110 and the adapter rod 160 can be a straight angle, so that the machine body is in a vertical state. The handle body 110 is not flipped relative to the machine body.

[0244] During the cleaning process of the cleaning equipment, there are many low-space scenes. Therefore, in the initial state of the handle assembly 100, the locking piece 130 can be arranged in the matching groove 1221a, so as to facilitate the folding of the handle body 110 relative to the machine body at any time, so that the handle body 110 can be quickly driven to fold relative to the machine body when encountering various low-space scenes.

[0245] It should be noted that the present application does not limit the telescopic state of the handle body 110 in the initial state of the handle assembly 100.

[0246] Reference Figures 8 to 11 As shown in the direction, when the driving assembly 141 moves to the left, the locking piece 130 can be separated from the matching groove 1221a and enter the limiting groove 140a. At this time, the handle body 110 cannot be folded. The locking pin assembly 142 can unlock the inner tube 112 and the outer sleeve tube 111, so as to adjust the length of the handle body 110. When the length adjustment of the handle body 110 is completed, the driving assembly 141 can be reset to the right, so that the locking piece 130 is separated from the limiting groove 140a and enters the matching groove 1221a. At this time, the handle body 110 cannot be telescoped.

[0247] The embodiments of the present application also provide a handle assembly 100 applied to cleaning equipment. The handle assembly 100 can include a handle body 110, a folding mechanism 120 and a telescopic mechanism 140.

[0248] The handle body 110 is directly or indirectly connected with the machine body of the cleaning equipment. The handle body 110 can be folded relative to the machine body. The inner tube 112 is slidably connected to the outer sleeve tube 111. The outer sleeve tube 111 is provided with a plurality of gear adjustment holes 111a.

[0249] The folding mechanism 120 can be used to achieve the clamping or flipping of the handle body 110 relative to the body. The telescopic mechanism 140 includes a transmission assembly 141 and a lock pin assembly 142. The lock pin assembly 142 includes a lock pin body 1421. The transmission assembly 141 moves along the length direction of the outer sleeve 111 to drive the lock pin body 1421 to switch between the locked state and the unlocked state.

[0250] When the lock pin body 1421 is in the locked state, the lock pin body 1421 is inserted into the gear adjustment hole 111a, and the inner tube 112 is fixed relative to the outer sleeve 111. When the lock pin body 1421 is in the unlocked state, the lock pin body 1421 is separated from the gear adjustment hole 111a, and the inner tube 112 can slide relative to the outer sleeve 111.

[0251] In the embodiments of the present application, the outer sleeve 111 is provided with a plurality of gear adjustment holes 111a. When the lock pin body 1421 is inserted into any gear adjustment hole 111a, the inner tube 112 can be fixed relative to the outer sleeve 111. When the lock pin body 1421 corresponds to different gear adjustment holes 111a, the handle body 110 can have different lengths.

[0252] When it is necessary to adjust the length of the handle body 110, the lock pin body 1421 can be first placed in the unlocked state, so that the lock pin body 1421 can be separated from the original gear adjustment hole 111a. Since the lock pin body 1421 is in the unlocked state, the inner tube 112 and the outer sleeve 111 can slide relative to each other. By sliding the inner tube 112 and the outer sleeve 111 relative to each other, the lock pin body 1421 can correspond to the target gear adjustment hole 111a. The lock pin body 1421 can be inserted into the target gear adjustment hole 111a to lock the inner tube 112 and the outer sleeve 111, thereby completing the adjustment of the length of the handle body 110.

[0253] In some examples, the plurality of gear adjustment holes 111a can be spaced apart along the length direction of the outer sleeve 111.

[0254] In some examples, the number of gear adjustment holes 111a is not limited in the embodiments of the present application. For example, the gear adjustment holes 111a can be three, four, five or even more.

[0255] In some examples, the distance between adjacent two gear adjustment holes 111a is not limited in the embodiments of the present application. For example, the plurality of gear adjustment holes 111a can be uniformly distributed on the outer sleeve 111. In other words, the distance between adjacent two gear adjustment holes 111a can be equal.

[0256] In some examples, the lock pin body 1421 can include a lock pin post. The inner tube 112 can be provided with an escape hole 112a. The lock pin post can correspond to the escape hole 112a. When the lock pin body 1421 is in the locked state, the lock pin post can correspond to one of the gear adjustment holes 111a, so that the lock pin post can be inserted into the gear adjustment hole 111a. The inner tube 112 and the outer sleeve 111 can be fixed. When the lock pin body 1421 is in the unlocked state, the lock pin post can be offset from the gear adjustment hole 111a in the length direction of the outer sleeve 111, and the inner tube 112 and the outer sleeve 111 can slide relative to each other.

[0257] In some examples, the lock pin body 1421 can include a lock pin post. The inner tube 112 can be provided with an escape hole 112a. The lock pin post can correspond to the escape hole 112a. When the lock pin body 1421 is in the locked state, the lock pin post can correspond to one of the gear adjustment holes 111a, so that the lock pin post can be inserted into the gear adjustment hole 111a. The inner tube 112 and the outer sleeve 111 can be fixed. When the lock pin body 1421 is in the unlocked state, the lock pin post can be offset from the gear adjustment hole 111a in the length direction of the outer sleeve 111, and the inner tube 112 and the outer sleeve 111 can slide relative to each other. Figure 9 In some examples, the lock pin body 1421 can include a lock pin post. The inner tube 112 can be provided with an escape hole 112a. The lock pin post can correspond to the escape hole 112a. When the lock pin body 1421 is in the locked state, the lock pin post can correspond to one of the gear adjustment holes 111a, so that the lock pin post can be inserted into the gear adjustment hole 111a. The inner tube 112 and the outer sleeve 111 can be fixed. When the lock pin body 1421 is in the unlocked state, the lock pin post can be offset from the gear adjustment hole 111a in the length direction of the outer sleeve 111, and the inner tube 112 and the outer sleeve 111 can slide relative to each other.

[0258] In some examples, the lock pin body 1421 can include a lock pin post. The inner tube 112 can be provided with an escape hole 112a. The lock pin post can correspond to the escape hole 112a. When the lock pin body 1421 is in the locked state, the lock pin post can correspond to one of the gear adjustment holes 111a, so that the lock pin post can be inserted into the gear adjustment hole 111a. The inner tube 112 and the outer sleeve 111 can be fixed. When the lock pin body 1421 is in the unlocked state, the lock pin post can be offset from the gear adjustment hole 111a in the length direction of the outer sleeve 111, and the inner tube 112 and the outer sleeve 111 can slide relative to each other.

[0259] Figures 8 to 11 In some examples, the lock pin body 1421 can include a lock pin post. The inner tube 112 can be provided with an escape hole 112a. The lock pin post can correspond to the escape hole 112a. When the lock pin body 1421 is in the locked state, the lock pin post can correspond to one of the gear adjustment holes 111a, so that the lock pin post can be inserted into the gear adjustment hole 111a. The inner tube 112 and the outer sleeve 111 can be fixed. When the lock pin body 1421 is in the unlocked state, the lock pin post can be offset from the gear adjustment hole 111a in the length direction of the outer sleeve 111, and the inner tube 112 and the outer sleeve 111 can slide relative to each other.

[0260] In some examples, the lock pin body 1421 can include a lock pin post. The inner tube 112 can be provided with an escape hole 112a. The lock pin post can correspond to the escape hole 112a. When the lock pin body 1421 is in the locked state, the lock pin post can correspond to one of the gear adjustment holes 111a, so that the lock pin post can be inserted into the gear adjustment hole 111a. The inner tube 112 and the outer sleeve 111 can be fixed. When the lock pin body 1421 is in the unlocked state, the lock pin post can be offset from the gear adjustment hole 111a in the length direction of the outer sleeve 111, and the inner tube 112 and the outer sleeve 111 can slide relative to each other.

[0261] ​The adapter 1422 can be used to transmit the force. The adapter 1422 can transmit the force of the transmission member to the lock pin assembly 142. In addition, the adapter 1422 can also be used to change the direction of the force. The adapter 1422 can convert the force of the transmission member along the length direction of the outer sleeve 111 into the force of the lock pin body 1421 moving along the axial direction of the gear adjusting hole 111a.

[0262] By setting the adapter 1422 to cooperate with the transmission assembly 141 and the lock pin assembly 142, the transmission assembly 141 and the lock pin assembly 142 can be arranged side by side along the axial direction of the gear adjusting hole 111a, which is beneficial to save the space inside the inner tube 112 along the length direction of the outer sleeve 111, so as to simplify the internal structure.

[0263] In some possible implementation manners, referring to Figure 9 and Figure 11 , the adapter 1422 of the embodiment of the present application can be provided with a first inclined adapter part 1422a. The lock pin body 1421 can be provided with a second inclined adapter part 1421a. The first inclined adapter part 1422a and the second inclined adapter part 1421a can cooperate with each other.

[0264] In the embodiment of the present application, the first inclined adapter part 1422a is arranged obliquely relative to the movement direction of the adapter 1422. The second inclined adapter part 1421a cooperates with the first inclined adapter part 1422a. The first inclined adapter part 1422a and the second inclined adapter part 1421a can realize the conversion of the direction of the force of the transmission assembly 141.

[0265] Referring to the direction shown in Figures 8 to 11 , when the transmission assembly 141 moves to the left along the length direction of the outer sleeve 111, the transmission assembly 141 can drive the adapter 1422 to move to the left. The first inclined adapter part 1422a and the second inclined adapter part 1421a cooperate with each other. The left movement of the adapter 1422 can provide the lock pin body 1421 with a movement space upward. The lock pin body 1421 can move upward so that the lock pin can be separated from the gear adjusting hole 111a, and the inner tube 112 and the outer sleeve 111 can slide relative to each other.

[0266] Correspondingly, when the transmission assembly 141 moves to the right along the length direction of the outer sleeve 111, the transmission assembly 141 can drive the adapter 1422 to move to the right. The right movement of the adapter 1422 can push the lock pin body 1421 to move downward, so that the lock pin is inserted into the gear adjusting hole 111a, and the inner tube 112 and the outer sleeve 111 are relatively fixed.

[0267] In some possible implementation manners, referring to Figure 8As shown, the locking pin assembly 142 of the embodiment of the present application can include a fixing member 1423. The fixing member 1423 can be arranged in the inner tube 112. The fixing member 1423 is internally provided with a sliding channel 1423a capable of accommodating at least part of the adapter 1422 and at least part of the locking pin body 1421. The sliding channel 1423a extends along the length direction of the outer sleeve 111.

[0268] The fixing member 1423 can be provided with a limiting sliding groove 1423b. One of the adapter 1422 and the transmission assembly 141 can pass through the limiting sliding groove 1423b to be connected with the other.

[0269] In the embodiment of the present application, the fixing member 1423 can provide a movement space for the adapter 1422. The sliding channel 1423a of the fixing member 1423 has a guiding effect on the movement direction of the adapter 1422.

[0270] The limiting sliding groove 1423b can be used to connect the transmission assembly 141 with the adapter 1422, so as to drive the adapter 1422 to move through the movement of the transmission assembly 141. In addition, the limiting sliding groove 1423b can have a limiting effect on the adapter 1422, so as to constrain the movement range of the adapter 1422 in the length direction of the outer sleeve 111, which is beneficial to improve the cooperation reliability of the locking pin and the gear adjusting hole 111a.

[0271] In some examples, part of the adapter 1422 can extend outside the limiting sliding groove 1423b to be connected with the transmission assembly 141. Alternatively, part of the transmission assembly 141 can extend into the sliding channel 1423a through the limiting sliding groove 1423b to be connected with the adapter 1422, which is not limited in the embodiment.

[0272] In some realizable modes, referring to Figure 10 As shown, the telescopic mechanism 140 of the embodiment of the present application can further include a telescopic trigger 143. The telescopic trigger 143 is connected with the transmission assembly 141. The telescopic trigger 143 is used to drive the transmission assembly 141 to move.

[0273] When the telescopic trigger 143 is not triggered, the adapter 1422 drives the locking pin body 1421 to be inserted into the gear adjusting hole 111a. When the telescopic trigger 143 is triggered, the adapter 1422 can make the locking pin body 1421 disengage from the gear adjusting hole 111a.

[0274] In the embodiment of the present application, the telescopic trigger 143 can provide an operable structure for the user. The user can trigger the telescopic trigger 143 to switch the locking pin body 1421 between the locked state and the unlocked state.

[0275] When the current length of the handle body 110 can meet the comfortable experience, the telescopic trigger 143 can not be triggered. At this time, the locking pin column of the locking pin body 1421 is inserted into the gear adjusting hole 111a, the inner tube 112 and the outer sleeve 111 are relatively fixed, and the length of the handle body 110 is fixed. When it is needed to adjust the length of the handle body 110, the telescopic trigger 143 can be triggered. The telescopic trigger 143 can drive the transmission assembly 141 to move, so that the transmission assembly 141 drives the adapter 1422 to transmit the force to the locking pin body 1421. The locking pin column of the locking pin body 1421 can be separated from the gear adjusting hole 111a, so that the inner tube 112 and the outer sleeve 111 can slide relatively, thereby adjusting the length of the handle body 110.

[0276] 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 direction of the outer sleeve 111.

[0277] Specifically, referring to the direction shown in Figures 8 to 11 When the telescopic trigger 143 rotates counterclockwise, the transmission assembly 141 can exert a force to the adapter 1422 towards the left. The adapter 1422 moves left in the slide 1423a, so that the first inclined adapter 1422a provides space for the locking pin body 1421 to move upward. The locking pin body 1421 can move upward to separate from the gear adjusting hole 111a. Correspondingly, when the telescopic trigger 143 rotates clockwise, the adapter 1422 moves right in the slide 1423a. The first inclined adapter 1422a can press the locking pin body 1421 to move downward, so that when the locking pin body 1421 corresponds to the gear adjusting hole 111a, the locking pin column of the locking pin body 1421 can be inserted into the gear adjusting hole 111a.

[0278] In some realizable ways, referring to Figure 11 The locking pin assembly 142 can further include a telescopic reset piece 1424. One end of the telescopic reset piece 1424 is connected with the fixed piece 1423. The other end of the telescopic reset piece 1424 is connected with the adapter 1422. The telescopic reset piece 1424 can be used to drive the telescopic trigger 143 to reset to the untriggered state.

[0279] In the embodiments of the present application, referring to Figures 8 to 11As shown, when the user triggers the telescopic trigger 143 to rotate counterclockwise, the transmission assembly 141 can drive the adapter 1422 to move left. At this time, the telescopic reset member 1424 can be deformed under the action of the adapter 1422. When the user removes the action on the telescopic trigger 143, the transmission assembly 141 releases the left action on the adapter 1422. At this time, the telescopic reset member 1424 can release the deformed action force, which can drive the adapter 1422 to move right, and drive the locking pin body 1421 to insert into the gear adjustment hole 111a through the adapter 1422. On the other hand, since the adapter 1422 is connected with the transmission assembly 141, the telescopic reset member 1424 can drive the transmission assembly 141 to move right through the adapter 1422, so that the telescopic trigger 143 moves clockwise to reset.

[0280] In some examples, the telescopic reset member 1424 can be, but is not limited to, a spring.

[0281] In some realizable modes, referring to Figures 8 to 11 As shown, the locking pin assembly 142 can 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 with the fixed member 1423, and the other end of the locking pin reset member 1425 is connected with the locking pin body 1421. The locking pin reset member 1425 can be used to drive the locking pin body 1421 to be separated from the gear adjustment hole 111a when the telescopic trigger 143 is triggered.

[0282] In the embodiment of the application, the locking pin reset member 1425 can be used to drive the locking pin body 1421 to switch from the locked state to the unlocked state. When the locking pin body 1421 is in the locked state, the locking pin reset member 1425 can be deformed. When the adapter 1422 moves left, the downward action of the adapter 1422 on the locking pin body 1421 is released. At this time, the locking pin reset member 1425 can release the deformed action force, so that the locking pin body 1421 can be separated from the gear adjustment hole 111a.

[0283] In some realizable modes, referring to Figure 8 As shown in FIGS. 11 and 12, the handle assembly 100 can further include a locking member 130. The transmission assembly 141 can drive the locking member 130 to move in the handle body 110. The folding mechanism 120 is provided with a cooperation groove 1221a, and when the locking member 130 cooperates with the cooperation groove 1221a, the locking pin body 1421 is in the locked state. The telescopic mechanism 140 is provided with a limiting groove 140a, and when the locking member 130 cooperates with the limiting groove 140a, the locking pin body 1421 is in the unlocked state.

[0284] In the embodiments of the present application, the locking member 130 switches between the matching groove 1221a and the limiting groove 140a, and the locking pin assembly 142 switches between the locked state and the unlocked state. Therefore, through the position of the locking member 130 and the state of the locking pin assembly 142, the independent folding and telescoping of the handle body 110 can be realized.

[0285] Specifically, when at least part of the locking member 130 is located in the matching groove 1221a, the folding mechanism 120 can move so that the handle body 110 can be clamped or flipped relative to the body. At this time, the locking pin assembly 142 is in the locked state, and the inner tube 112 and the outer sleeve 111 are locked by the locking pin assembly 142, so that the inner tube 112 and the outer sleeve 111 are relatively fixed during the flipping of the handle body 110.

[0286] 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 sleeve 111 can be unlocked by the locking pin assembly 142 to adjust the length of the handle body 110 by the relative sliding of the inner tube 112 and the outer sleeve 111. Moreover, the position of the locking member 130 can make the handle body 110 unable to flip relative to the body.

[0287] In some realizable modes, referring to Figure 10 As shown, the transmission assembly 141 can include a connecting rod 1411 and a sliding block 1412. One end of the connecting rod 1411 is connected with the sliding block 1412, and the other end of the connecting rod 1411 is connected with the telescopic trigger 143.

[0288] The sliding block 1412 can be used to drive the adapter 1422 to move along the length direction of the outer sleeve 111, and the sliding block 1412 is used to drive the locking member 130 to switch between the folding mechanism 120 and the sliding block 1412.

[0289] In the embodiments of the present application, the connecting rod 1411 and the sliding block 1412 can be used to transmit force, so that when the telescopic trigger 143 is triggered, the adapter 1422 can be driven to move by the connecting rod 1411 and the sliding block 1412, so that the locking pin assembly 142 is in the locked state or the unlocked state. The connecting rod 1411 and the sliding block 1412 have the advantages of simple structure and high reliability.

[0290] In some examples, the connecting rod 1411 is rotatably connected with the telescopic trigger 143. The connecting rod 1411 is rotatably connected with the sliding block 1412. The sliding block 1412 can move along the length direction of the outer sleeve 111.

[0291] In some realizable modes, referring to Figures 8 to 11As shown, the handle assembly 100 can further include a linkage 1222. At least part of the linkage 1222 can be located in the inner tube 112. The linkage 1222 and the inner wall of the inner tube 112 can form an inner space for the transmission assembly 141 to move along the length direction of the outer sleeve 111.

[0292] In the embodiments of the present application, the linkage 1222 and the locking member 130 can move synchronously. When the locking member 130 is located in the limiting slot 140a, the sliding of the linkage 1222 can be used to realize the relative sliding of the inner tube 112 and the outer sleeve 111. Moreover, the linkage 1222 and the inner wall of the inner tube 112 can form an inner space having a guiding effect on the slider 1412.

[0293] In some implementable manners, referring to Figures 8 to 11 As shown, the folding mechanism 120 can further include a first traction body 1221, which is slidably connected to the linkage 1222. The first traction body 1221 is provided with a matching slot 1221a, and the linkage 1222 is provided with a locking hole 122a for the locking member 130 to pass through. When the locking member 130 is located in the locking hole 122a and the matching slot 1221a, the first traction body 1221 and the linkage 1222 move synchronously, and the first traction body 1221 drives the handle body 110 to be clamped or flipped relative to the machine body.

[0294] In some implementable manners, referring to Figure 2 As shown, the slider 1412 is provided with a limiting slot 140a. When the locking member 130 is located in the limiting slot 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 sleeve 111.

[0295] The embodiments of the present application further provide a cleaning device, referring to Figure 10 As shown, the cleaning device can include a machine body and the handle assembly 100 in any of the above embodiments. The handle assembly 100 is connected to the machine body.

[0296] In some examples, the cleaning device can further include a clean water tank and a dirty water tank. The clean water tank and the dirty water tank can be arranged on the brush assembly or the machine body. Alternatively, one of the clean water tank and the dirty water tank can be arranged on the brush assembly, and the other can be arranged on the machine body. The embodiments of the present application are not limited in this regard.

[0297] The embodiments of the present application further provide a cleaning system. The cleaning system can include a base or a station. The cleaning device can be placed on the base or the station.

[0298] In some examples, the base can be used to wash the roller brush and dry the roller brush to avoid the generation of odor or bacteria due to the long time of the roller brush in a wet state.

[0299] In some examples, the base station can have a charging function. When the cleaning device is placed on the base station, the base station can be charged, and the water can be automatically supplied and discharged. The base and the base station can be a split structure, or the base and the base station can be an integrated structure, which is not limited in the embodiments of the present application.

[0300] Referring to Figure 10 The handle assembly 100 of the embodiments of the present application can be applied to a cleaning device. The handle assembly 100 can include a handle body 110, a folding mechanism 120, a locking member 130, and a telescopic mechanism 140.

[0301] The handle body 110 is directly or indirectly connected to the body of the cleaning device. The handle body 110 can be flipped relative to the body. The inner tube 112 is slidably connected to the outer sleeve 111, and the outer sleeve 111 is provided with a plurality of gear adjustment holes 111a distributed along the length direction thereof.

[0302] The folding mechanism 120 can be provided on the handle body 110. The folding mechanism 120 is provided with a plurality of cooperation grooves 1221a distributed along the length direction thereof. The locking member 130 cooperates with the cooperation grooves 1221a to drive the folding mechanism 120 to engage or flip the handle body 110 relative to the body.

[0303] The telescopic mechanism 140 is provided on the handle body 110. The telescopic mechanism 140 can include a locking pin assembly 142. The locking pin assembly 142 is inserted into or separated from the gear adjustment hole 111a to lock the outer sleeve 111 and the inner tube 112 or realize the telescopic sliding of the inner tube 112 relative to the outer sleeve 111.

[0304] The number of the gear adjustment holes 111a is less than or equal to the number of the cooperation grooves 1221a, and the interval between the adjacent two gear adjustment holes 111a is equal to the interval between the adjacent two cooperation grooves 1221a.

[0305] 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.

[0306] 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.

[0307] 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.

[0308] 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.

[0309] 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.

[0310] In some possible implementation manners, referring to Figure 8 When the locking pin assembly 142 is inserted into the gear adjustment hole 111a, the locking member 130 is located in the matching groove 1221a.

[0311] In the embodiment, when the locking pin assembly 142 is inserted into the gear adjustment hole 111a, the inner tube 112 is locked with the outer sleeve 111, and at this time, the locking member 130 is located in the matching groove 1221a, so as to drive the handle body 110 to be clamped or flipped relative to the machine body. Therefore, the movement of clamping or flipping the handle body 110 relative to the machine body and the telescopic movement of the handle body 110 cannot be performed simultaneously. In other words, the movement of clamping or flipping the handle body 110 relative to the machine body and the telescopic movement of the handle body 110 need to be operated step by step, which is beneficial to improve the reliability of the movement of clamping or flipping the handle body 110 relative to the machine body and the telescopic movement of the handle body 110, and can facilitate the user to control the state of the handle body 110.

[0312] In some possible implementation manners, referring to Figure 10 The distribution direction of the gear adjustment hole 111a is parallel to the distribution direction of the matching groove 1221a.

[0313] In the embodiment, by setting the distribution direction of the gear adjustment hole 111a parallel to the distribution direction of the matching groove 1221a, when the inner tube 112 is adjusted to slide relative to the outer sleeve 111, it can be ensured that the locking member 130 is located in the corresponding matching groove 1221a when the locking pin assembly 142 is inserted into different gear adjustment holes 111a, so as to avoid the locking member 130 deviating or separating from the matching groove 1221a, thereby reducing the possibility of affecting the movement of clamping or flipping the handle body 110 relative to the machine body.

[0314] In some possible implementation manners, referring to Figure 10 When the inner tube 112 slides relative to the outer sleeve 111, the locking pin assembly 142 slides through at least one gear adjustment hole 111a, and the locking member 130 corresponds to slide through the same number of matching grooves 1221a.

[0315] In the embodiment, during the relative sliding of the inner tube 112 and the outer sleeve 111, the number of the gear adjustment holes 111a through which the locking pin assembly 142 passes is equal to the number of the matching grooves 1221a through which the locking member 130 corresponds to slide, so that when the handle body 110 corresponds to different gear lengths, the clamping or flipping movement of the handle body 110 relative to the machine body can be realized, and the possibility of affecting the clamping or flipping movement of the handle body 110 relative to the machine body or even affecting the telescopic movement of the handle body 110 due to the locking member 130 entering the misaligned matching groove 1221a is avoided.

[0316] It is easy to understand that the telescopic distance of the handle body 110 can be equal to the interval of all the matching grooves 1221a through which the locking member 130 slides.

[0317] Exemplarily, referring to the directions shown in Figures 8 to 11 When the matching grooves 1221a are equal in number to the gear adjustment holes 111a, the locking pin assembly 142 is moved from the first left gear adjustment hole 111a to the third left gear adjustment hole 111a, and the locking member 130 is moved from the first left matching groove 1221a to the third left matching groove 1221a.

[0318] In some possible implementation manners, referring to the directions shown in Figure 10 The telescopic mechanism 140 of the embodiment of the application can include a transmission assembly 141. The transmission assembly 141 can be provided with a limiting groove 140a. The transmission assembly 141 moves along the length direction of the outer sleeve tube 111 to drive the locking member 130 to switch between the matching grooves 1221a and the limiting groove 140a.

[0319] The transmission assembly 141 is connected with the locking pin assembly 142. The transmission assembly 141 drives the locking pin assembly 142 to insert into or separate from the gear adjustment hole 111a. When the locking pin assembly 142 separates from the gear adjustment hole 111a, the locking member 130 can be located in the limiting groove 140a.

[0320] In the embodiment of the application, the transmission assembly 141 can be used to drive the locking member 130 to switch between the matching grooves 1221a and the limiting groove 140a. When the locking member 130 is located in the matching groove 1221a, the locking pin assembly 142 locks the outer sleeve tube 111 and the inner tube 112, so that the length of the handle body 110 is fixed. At this time, the handle body 110 can be clamped or flipped relative to the machine body. When the locking member 130 is located in the limiting groove 140a, the locking member 130 separates from the matching groove 1221a, and the handle body 110 cannot be clamped or flipped relative to the machine body. The transmission assembly 141 can make the locking pin assembly 142 separate from the gear adjustment hole 111a, so as to realize the telescopic sliding of the inner tube 112 relative to the outer sleeve tube 111.

[0321] Therefore, by setting the locking member 130 to switch between the matching grooves 1221a and the limiting groove 140a, the clamping or flipping movement of the handle body 110 relative to the machine body and the telescopic sliding of the inner tube 112 relative to the outer sleeve tube 111 can be limited to be synchronous. In other words, the clamping or flipping movement of the handle body 110 relative to the machine body and the telescopic sliding of the inner tube 112 relative to the outer sleeve tube 111 need to be operated step by step.

[0322] In some examples, when the locking piece 130 is located in the matching groove 1221a, the matching groove 1221a and the limiting groove 140a can be staggered in the length direction of the outer sleeve 111 to avoid the locking piece 130 from being disengaged from the matching groove 1221a to the limiting groove 140a.

[0323] In some realizable manners, referring to FIG. 1, 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 matching groove 1221a and the limiting groove 140a are opposite. Figures 8 to 11

[0324] In the embodiments of the present application, 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 tube 112 and save the length of the inner tube 112 in the length direction thereof. The folding mechanism 120 and the telescopic mechanism 140 are compact in structure, which is conducive to the miniaturization and weight reduction design of the cleaning device.

[0325] In the embodiments of the present application, the opening directions of the matching groove 1221a and the limiting groove 140a are opposite, which can facilitate the switching of the locking piece 130 between the two.

[0326] In some realizable manners, referring to FIG. 1, the folding mechanism 120 can include a first traction body 1221 and a linkage 1222. The first traction body 1221 is slidably connected to the linkage 1222. The first traction body 1221 is provided with a matching groove 1221a, and the linkage 1222 is provided with a locking hole 122a. When the locking pin assembly 142 is inserted into the gear adjusting hole 111a, the locking piece 130 is located in the locking hole 122a and one of the matching grooves 1221a. The first traction body 1221 is used to drive the handle body 110 to be clamped or rotated relative to the machine body. Figure 10 In the embodiments of the present application, when the locking piece 130 is located in the locking hole 122a and one of the matching grooves 1221a, the locking piece 130 can lock the first traction body 1221 and the linkage 1222 relative to each other. The first traction body 1221 and the linkage 1222 can move synchronously to enable the handle body 110 to be clamped or flipped 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 adjusting hole 111a, the outer sleeve 111 and the inner tube 112 can be locked relative to each other, and the length of the handle body 110 is not adjustable.

[0327] In some realizable manners, referring to FIG. 1, the folding mechanism 120 can include a first traction body 1221 and a linkage 1222. The first traction body 1221 is slidably connected to the linkage 1222. The first traction body 1221 is provided with a matching groove 1221a, and the linkage 1222 is provided with a locking hole 122a. When the locking pin assembly 142 is inserted into the gear adjusting hole 111a, the locking piece 130 is located in the locking hole 122a and one of the matching grooves 1221a. The first traction body 1221 is used to drive the handle body 110 to be clamped or rotated relative to the machine body.

[0328] Figures 8 to 11 ​​As shown, the transmission assembly 141 of the embodiment of the present application can include a slider 1412 for driving the locking pin assembly 142. The slider 1412 can be provided with a limiting slot 140a. When the locking pin assembly 142 is disengaged from the gear adjustment hole 111a, the locking hole 122a corresponds to the limiting slot 140a. The locking member 130 is located in the locking hole 122a and the limiting slot 140a.

[0329] In the embodiment of the present application, at least part of the linkage 1222 can be located in the inner tube 112. The side wall of the linkage 1222 and the inner wall of the inner tube 112 can form a guide space for the slider 1412 to slide along the length direction of the outer sleeve tube 111.

[0330] The sliding of the slider 1412 along the length direction of the outer sleeve tube 111 can have the effect of driving the locking member 130 to switch in the matching slot 1221a and the limiting slot 140a. Also, it can drive the locking pin assembly 142 to lock the outer sleeve tube 111 and the inner tube 112 or realize the telescopic sliding of the inner tube 112 relative to the outer sleeve tube 111. Therefore, through the movement of the slider 1412, the locking pin assembly 142 and the locking member 130 can be synchronously driven, so that when the locking pin assembly 142 corresponds to the gear adjustment hole 111a, the locking member 130 can be located in the matching slot 1221a corresponding to the gear adjustment hole 111a.

[0331] The embodiment of the present application also provides a cleaning device, which can include a machine body and the handle assembly 100 in any of the above embodiments. The handle assembly 100 is connected to the machine body.

[0332] In some examples, the cleaning device can also include a clean water tank and a dirty water tank. The clean water tank and the dirty water tank can be arranged on the floor brush assembly or on the machine body. Alternatively, one of the clean water tank and the dirty water tank can be arranged on the floor brush assembly and the other can be arranged on the machine body. The embodiment of the present application is not limited in this regard.

[0333] The embodiment of the present application also provides a cleaning system. The cleaning system can include a base or a station. The cleaning device can be placed on the base or the station.

[0334] In some examples, the base can be used to wash the roller brush and dry the roller brush to avoid the generation of odor or bacteria due to the long time of the roller brush in a wet state.

[0335] In some examples, the station can have a charging function. When the cleaning device is placed on the station, the station can be charged, and the water can be automatically supplied and drained. The base and the station can be a split structure or an integrated structure, which is not limited in the embodiment of the present application.

[0336] In some realizable modes, referring to Figures 8 to 13As shown, the handle assembly 100 of the embodiments of the present application can be applied to a cleaning device. The handle assembly 100 can include a handle body 110, a folding mechanism 120 and a telescopic mechanism 140.

[0337] The handle body 110 is directly or indirectly connected with a body of the cleaning device. The handle body 110 can be flipped relative to the body, and the inner tube 112 is slidably connected with the outer sleeve 111.

[0338] The folding mechanism 120 is arranged on the handle body 110. The folding mechanism 120 can include a folding trigger 121. The folding trigger 121 is arranged on the handle body 110. The folding trigger 121 is used to control the handle body 110 to be clamped or flipped relative to the body.

[0339] The telescopic mechanism 140 is arranged on the handle body 110. The telescopic mechanism 140 includes a telescopic trigger 143. The telescopic trigger 143 is arranged on the handle body 110. The telescopic trigger 143 is used to control the inner tube 112 to slide or lock relative to the outer sleeve 111.

[0340] The operation part 1211 of the folding trigger and the operation part 1431 of the telescopic trigger have a barrier therebetween.

[0341] In the embodiments of the present application, the user can trigger the operation part 1211 of the folding trigger to make the handle body 110 clamped or flipped relative to the body, so that the body is in a lying state, thereby being used to clean low space. The user can trigger the operation part 1431 of the telescopic trigger to control the inner tube 112 to slide or lock relative to the outer sleeve 111, so as to adjust the length of the handle body 110, thereby being suitable for users of different heights and different application scenarios.

[0342] Since the operation part 1211 of the folding trigger and the operation part 1431 of the telescopic trigger are both arranged on the handle body 110, when the user holds the handle body 110 to clean the surface to be cleaned, one of the operation part 1211 of the folding trigger and the operation part 1431 of the telescopic trigger is driven, the other one is easily mistaken, thereby affecting the movement state of the handle body 110 and affecting the normal use of the user.

[0343] Therefore, a barrier can be arranged between the operation part 1211 of the folding trigger and the operation part 1431 of the telescopic trigger. The barrier can be a spatial barrier, and the operation part 1211 of the folding trigger and the operation part 1431 of the telescopic trigger can have a large spacing therebetween, so that when one of them is triggered, the user's finger can not easily touch the other one, thereby reducing the possibility of mistaken triggering.

[0344] 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.

[0345] 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.

[0346] 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.

[0347] 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.

[0348] 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.

[0349] 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.

[0350] 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.

[0351] 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.

[0352] 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.

[0353] 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.

[0354] 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.

[0355] 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.

[0356] 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.

[0357] 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.

[0358] 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.

[0359] Only one of the operating parts 1211 of the folding trigger and 1431 of the telescopic trigger is located in the gripping space 170a.

[0360] 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.

[0361] 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.

[0362] 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.

[0363] 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.

[0364] 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.

[0365] 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.

[0366] 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.

[0367] 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.

[0368] 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.

[0369] 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.

[0370] 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.

[0371] 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.

[0372] 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.

[0373] 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.

[0374] 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.

[0375] 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.

[0376] 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.

[0377] 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.

[0378] 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.

[0379] 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.

[0380] 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.

[0381] 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.

[0382] 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.

[0383] 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.

[0384] 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.

[0385] 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.

[0386] 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.

[0387] 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.

[0388] 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.

[0389] 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.

[0390] 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.

[0391] 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.

[0392] 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.

[0393] 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.

[0394] 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.

[0395] 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.

[0396] 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.

[0397] 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.

[0398] 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.

[0399] 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.

[0400] 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.

[0401] 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.

[0402] 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.

[0403] 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.

[0404] 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.

[0405] 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.

[0406] 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.

[0407] 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.

[0408] 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.

[0409] 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.

[0410] 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.

[0411] 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.

[0412] 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.

[0413] 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.

[0414] 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.

[0415] 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.

[0416] 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.

[0417] 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.

[0418] 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.

[0419] 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.

[0420] 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.

[0421] 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.

[0422] 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.

[0423] 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.

[0424] 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.

[0425] 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.

[0426] 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.

[0427] 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.

[0428] 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.

[0429] 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.

[0430] 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.

[0431] 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.

[0434] 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.
