Description

[0001] This application claims the priority of a Chinese patent application with the application number 202520177911.5 and the application title "Handle Assembly, Cleaning Device and Cleaning System" filed with the Chinese Patent Office on January 27, 2025, and all or part of its content is incorporated into this application by reference. Technical Field

[0002] This application relates to the field of cleaning technology, and particularly relates to a handle assembly, a cleaning device and a cleaning system. Background Art

[0003] Cleaning devices such as floor washers and vacuum cleaners are intelligent products and are widely used in people's daily lives. Taking the floor washer as an example, a floor washer is a cleaning machine suitable for cleaning surfaces such as floors and carpets, and can simultaneously suck up sewage and take the sewage away from the site, with advantages such as environmental protection, energy saving and high efficiency.

[0004] The floor washer includes a handle assembly, a floor brush assembly and a body. The body is used to connect the handle assembly and the floor brush assembly. The user can hold the handle assembly to drive the floor brush assembly to clean the surface to be cleaned. The body of the traditional floor washer cannot lie flat during the cleaning process, and the floor washer cannot effectively clean low spaces.

[0005] In related technologies, the movement mode of the handle assembly is single. The handle assembly can be flipped relative to the body, or the handle assembly can be telescopic. However, for users of different heights or when cleaning low spaces, the handle assembly is difficult to meet the comfort of use and affects the user experience. Summary of the Invention

[0006] This application provides a handle assembly, a cleaning device and a cleaning system, which can solve the problem that the movement mode of the handle assembly is single and it is difficult to meet the usage requirements of users of different heights and different application scenarios.

[0007] In a first aspect, this application provides a handle assembly, which includes:

[0008] A handle body, the handle body is directly or indirectly connected to the body of the cleaning device, the handle body can be flipped relative to the body through a rotating shaft, and the handle body includes a slidable inner tube and an outer tube;

[0009] A grip;

[0010] A folding mechanism, at least part of the folding mechanism is located in the inner tube, the folding mechanism includes a folding trigger, the folding trigger is arranged on the grip, and the folding trigger is used to control the engagement or flipping of the handle body relative to the body;

[0011] A telescopic mechanism, the telescopic mechanism and the folding mechanism are arranged side by side within the inner tube, the telescopic mechanism is located between the rotating shaft and the handle grip, the telescopic mechanism includes a telescopic trigger, the telescopic trigger is arranged on the handle grip, and the telescopic trigger is used to control the sliding or locking of the inner tube relative to the outer tube.

[0012] For the handle assembly provided in this application, the body is used to connect the handle assembly and the floor brush assembly. The body is rotatably connected to the handle main body of the handle assembly through a rotating shaft. Therefore, it is easy to understand that the rotating shaft is closer to the surface to be cleaned relative to the handle main body. The user can operate at one end of the handle main body away from the rotating shaft. When cleaning a low space, the user can operate the folding trigger to enable the handle main body to rotate through the rotating shaft. The body and the surface to be cleaned can tend to be horizontal, and the body is in a lying flat state. At this time, there is an inclined angle between the handle main body and the body. The user can extend at least part of the body into the low space without bending down to clean the surface to be cleaned in the low space.

[0013] Moreover, since the inner tube of the embodiment of this application can slide along the length direction of the outer tube. When the body is in a lying flat state, the user can adjust the length of the inner tube extending out of the outer tube to meet the usage requirements of users of different heights.

[0014] According to an embodiment of this application, the folding trigger is located between a part of the handle grip and the handle main body.

[0015] In this application, the handle grip is close to the user for the user to hold the handle grip. By arranging the folding trigger between the handle grip and the handle main body, the folding trigger can be arranged close to the handle grip. Therefore, when the user holds the handle grip, the fingers can be placed on the folding trigger conveniently to trigger the folding trigger, so as to realize the flipping of the handle main body relative to the body.

[0016] According to an embodiment of this application, the telescopic trigger is located at one end of the inner tube away from the body, and the folding trigger is located in the length direction of the outer tube.

[0017] In this application, by arranging the folding trigger at one end of the inner tube away from the body, the folding trigger can be closer to the user relative to the inner tube to facilitate the user to operate the folding trigger. By arranging the folding trigger in the length direction of the outer tube, the inner tube can be moved along the length direction of the outer tube by operating the folding trigger. In other words, the inner tube can only have a linear motion to save the internal space of the outer tube, which is beneficial to reducing the possibility that the inner tube flips or bends and occupies a large internal space of the outer tube.

[0018] The moving direction of the folding trigger can be the same as the longitudinal direction of the outer sleeve. Therefore, the moving direction of the folding trigger can be the same as the moving direction of the inner tube. The linear movement of the folding trigger can cause the inner tube to also move linearly, reducing the complexity of power transmission.

[0019] According to an embodiment of the present application, the grip is provided at one end of the inner tube away from the fuselage; the grip includes a first gripping portion, and the telescopic trigger is located between the first gripping portion and the inner tube.

[0020] In the present application, when the user holds the first gripping portion with the hand, at least part of the fingers can be placed in the space between the first gripping portion and the inner tube. Therefore, at least part of the user's fingers can easily touch the telescopic trigger between the first gripping portion and the inner tube. The user can operate the telescopic trigger when holding the first gripping portion without visual participation.

[0021] According to an embodiment of the present application, there is a barrier between the folding trigger and the display screen on the grip.

[0022] In the present application, a display screen is provided on the grip. Herein, the display screen can refer to the display screen existing on the grip in the related art. The display screen can have a display function. Or, the display screen can also have display and touch functions. By having a barrier between the folding trigger and the display screen, on the one hand, the barrier can be used to provide support for the display screen. On the other hand, according to ergonomics, by having a barrier between the folding trigger and the display screen, there can be a spacing between the folding trigger and the display screen. When the user holds the grip with the palm of the hand, the thumb can directly operate the display screen or the operation keys near the display screen. When the remaining four fingers are placed downwards along the trend, one of the fingers (such as the index finger) can easily touch the folding trigger.

[0023] According to an embodiment of the present application, there is a barrier between the folding trigger and the operation keys on the grip.

[0024] In the present application, the barrier between the folding trigger and the operation keys can separate the folding trigger and the operation keys. There is a spacing between the folding trigger and the operation keys so that when the user holds the grip, it can conform to ergonomics, thereby improving the comfort of the user's operation of the folding trigger and the operation keys. Specifically, when the user holds the handgrip on the first gripping portion, the thumb can easily operate the operation keys, and the remaining four fingers can be placed downwards along the trend so that one of the remaining four fingers (such as the index finger) can touch the folding trigger along the trend. Thus, the user can operate the folding trigger and the operation keys without switching fingers and without too much visual participation.

[0025] According to an embodiment of the present application, in the thickness direction of the display screen, at least a part of the orthographic projection of the folding trigger is located inside the orthographic projection of the display screen.

[0026] In the present application, through the above arrangement, it can be ensured that the display screen is not easily blocked by the palm or fingers. Moreover, when the user needs to operate the folding trigger when viewing the display screen, the user does not need to shift the line of sight anymore and can easily trigger the folding trigger. Specifically, when the user holds the grip, according to the user's holding habit, the positions of the thumb and the palm are not likely to block the display screen, facilitating the user to view the display screen. At this time, when the other four fingers are placed downwards along the trend, one of the fingers can be easily placed on the folding trigger.

[0027] According to an embodiment of the present application, in the pressing direction of the operation key, at least a part of the orthographic projection of the folding trigger overlaps with the orthographic projection of the operation key.

[0028] In the present application, through the above arrangement, when the operation key is not easily blocked by the palm or fingers, the user can easily trigger the folding trigger. Moreover, when the user can easily trigger the folding trigger, the operation key is not easily blocked by the palm or fingers and misoperation occurs.

[0029] Specifically, the grip faces the user so that the operation key faces the user. When the user holds the grip, the positions of the thumb and the palm will consciously not block the operation key to facilitate the operation of the operation key. At this time, according to ergonomics, when the other four fingers are placed downwards along the trend, one of the fingers can be easily placed on the folding trigger. Therefore, when the user triggers the folding trigger, the line of sight does not need to be switched.

[0030] According to an embodiment of the present application, the handle body is rotatably connected to the fuselage through a rotating shaft, and the telescopic mechanism is located between the rotating shaft and the grip.

[0031] In the present application, at least a part of the telescopic mechanism moves inside the inner tube. The telescopic mechanism can be used to realize the telescoping of the handle body. Since the inner tube can slide along the length direction of the outer tube, by arranging the telescopic mechanism between the rotating shaft and the grip, the space between the rotating shaft and the grip can be reasonably utilized, which is beneficial to reducing the possibility that the telescopic mechanism occupies extra space and causes the length dimension of the handle body to be too large, thus making it difficult to meet the usage requirements of users of different heights.

[0032] According to an embodiment of the present application, the telescopic mechanism includes a telescopic reset member, and the telescopic reset member is arranged on the handle body and is used to drive the telescopic trigger to reset;

[0033] Along the length direction of the outer sleeve, the telescopic trigger member and the telescopic reset member are respectively located at two ends of the inner tube.

[0034] In this application, when the telescopic trigger member is triggered, the handle body can be telescopic to adjust the length of the handle body. When the user releases the triggering driving force on the telescopic reset member, the telescopic reset member can be used to drive the telescopic trigger member to reset to the untriggered state. At this time, the length of the handle body can be locked.

[0035] According to an embodiment of the present application, the telescopic mechanism further includes a transmission assembly and a locking pin assembly. The transmission assembly connects the telescopic trigger member and the locking pin assembly. The telescopic trigger member drives the locking pin assembly to move, and the locking pin assembly is used to lock or unlock the inner tube and the outer sleeve.

[0036] The telescopic reset member is connected to the locking pin assembly, and the telescopic reset member is used to drive the locking pin assembly to reset.

[0037] In this application, the telescopic reset member can, on the one hand, have the function of driving the telescopic trigger member to reset, and on the other hand, can also have the function of driving the locking pin assembly to lock or unlock the inner tube and the outer sleeve.

[0038] Specifically, when the telescopic trigger member is triggered, the transmission assembly can transmit the acting force to drive the locking pin assembly to move. At this time, the locking pin assembly can unlock the inner tube and the outer sleeve to adjust the length of the handle body. And the movement of the locking pin assembly can also make the telescopic reset member in a compressed state, and the telescopic reset member can accumulate the acting force of deformation.

[0039] When the triggering driving force of the telescopic trigger member is released, on the one hand, the telescopic reset member can drive the telescopic trigger member to reset, and on the other hand, the telescopic reset member can release the elastic potential energy and transmit it to the telescopic trigger member through the transmission assembly, so that the telescopic trigger member can reset.

[0040] According to an embodiment of the present application, the telescopic trigger member is connected to the transmission assembly, and the transmission assembly moves forward or backward in the inner tube.

[0041] In this application, by setting the transmission assembly to move forward or backward in the inner tube, the locking pin assembly can be in a locked state or an unlocked state. When the locking pin assembly is in the locked state, the inner tube and the outer sleeve are relatively fixed. When the locking pin assembly is in the unlocked state, the inner tube and the outer sleeve can slide relative to each other.

[0042] Since the telescopic trigger is connected to the transmission assembly, the telescopic trigger can cause the transmission assembly to move forward or backward within the inner tube. The telescopic trigger can be movably connected to the handle body for driving the transmission assembly to move forward or backward. Among them, the telescopic trigger can be, but is not limited to, slidably connected to the handle body, or the telescopic trigger can be flipped relative to the handle body, which is not specifically limited in this application.

[0043] According to an embodiment of the present application, the telescopic trigger has a triggering movement and a reset movement;

[0044] When the telescopic trigger makes a triggering movement, the transmission assembly moves leftward along the length direction of the outer tube, and the inner tube and the outer tube can slide relative to each other;

[0045] When the telescopic trigger makes a reset movement, the transmission assembly moves rightward along the length direction of the outer tube, and the inner tube and the outer tube are relatively fixed.

[0046] In this application, the telescopic trigger can be slidably connected to the handle body. When the telescopic trigger makes a triggering movement, the telescopic trigger can slide leftward to drive the transmission assembly to move leftward synchronously along the length direction of the outer tube. Since the transmission assembly is connected to the lock pin assembly. When the transmission assembly moves leftward, it can cause the adapter of the lock pin assembly to slide leftward. At this time, the lock pin body can be disengaged from the gear adjustment hole of the outer tube, so that the lock pin assembly is unlocked from the handle body, and the inner tube of the handle body can slide relative to the outer tube.

[0047] When the telescopic trigger makes a reset movement, the telescopic trigger can slide rightward to drive the transmission assembly to move rightward along the length direction of the outer tube. Since the transmission assembly is connected to the lock pin assembly. When the transmission assembly moves rightward, it can cause the adapter of the lock pin assembly to slide rightward. At this time, the lock pin body can be inserted into the gear adjustment hole of the outer tube under the action of the adapter. The lock pin body can lock the handle body. The inner tube of the handle body is fixed relative to the outer tube.

[0048] According to an embodiment of the present application, the grip further includes a second holding portion, and there is a holding space between the first holding portion and the second holding portion;

[0049] Only one of the operating portion of the folding trigger and the operating portion of the telescopic trigger is located in the holding space.

[0050] In this application, when only one of the operating portion of the folding trigger and the operating portion of the telescopic trigger is located in the holding space, the other can be located outside the holding space. Therefore, the first holding portion and / or the second holding portion can be used to block the operating portion of the folding trigger and the operating portion of the telescopic trigger, so that when one of them is triggered, it is not easy to accidentally trigger the other.

[0051] According to an embodiment of the present application, the folding trigger and the telescopic trigger are located at an end of the handle body away from the body, and there is a barrier between the operating portion of the folding trigger and the operating portion of the telescopic trigger.

[0052] In the present application, by arranging the folding trigger and the telescopic trigger at one end of the handle body away from the body, the folding trigger and the telescopic trigger can be close to the user, so as to facilitate the user to operate the folding trigger and the telescopic trigger.

[0053] Since the folding trigger and the telescopic trigger are located at the same end of the handle body, by arranging a barrier between the operating portion of the folding trigger and the operating portion of the telescopic trigger, when one of the folding trigger and the telescopic trigger 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.

[0054] In a second aspect, a cleaning device provided by the present application includes: a body and the handle assembly in any of the above embodiments. The handle assembly is connected to the body.

[0055] In a third aspect, a cleaning system provided by the present application includes a base or a base station. The cleaning device can be placed on the base or the base station.

[0056] The beneficial effect of the handle assembly provided by the present application is that when cleaning a low space, the user can operate the folding trigger to make the handle body rotate through the rotating shaft. The body and the surface to be cleaned can tend to be horizontal, and the body is in a lying state. At this time, there is an inclination angle between the handle body and the body. The user can extend at least part of the body into the low space without bending down to clean the surface to be cleaned in the low space.

[0057] Moreover, when the user holds the grip, the folding trigger can be easily touched. The fingers can be easily placed on it to operate the folding trigger without too much visual participation. Moreover, when the user holds the grip, the folding trigger can be easily operated without easily blocking the display screen and / or the operation keys.

[0058] In addition, the user can operate the folding trigger and the telescopic trigger separately, so that when one of them is triggered, it is not easy to accidentally touch the other, thereby reducing the possibility that the telescopic movement and the flipping movement of the handle body occur simultaneously, making it difficult for the user to operate.

[0059] In addition to the technical problems solved by the embodiments of the present invention described above, the technical features constituting the technical solutions, and the beneficial effects brought by the technical features of these technical solutions, other technical problems that can be solved by the handle assembly, cleaning device, and cleaning system provided by the embodiments of the present invention, 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.

[0097] Through the above - mentioned drawings, the specific embodiments of the present application have been shown, and there will be more detailed descriptions hereinafter. These drawings and textual descriptions are not intended to limit the scope of the concept of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. Specific embodiments

[0098] Here, the exemplary embodiments will be described in detail, and the examples are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all the embodiments consistent with the present application. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts fall within the scope of protection of the present application.

[0099] A cleaning device provided by an embodiment of the present application can be, but is not limited to, a floor washer, an electric broom, an electric mop, a vacuum cleaner. Taking the floor washer as an example, a floor washer is a device for cleaning the floor. Among them, the floor can be, but is not limited to, a floor, a tile, a carpet, etc.

[0100] A floor scrubber is generally composed of a floor brush assembly, a roller brush, a clean water tank, a sewage tank, and other parts. The working principle of a floor scrubber is as follows: the high-speed operation of the motor drives the roller brush to rotate at high speed, while the clean water tank operates, spraying clean water forward through the water channel onto the roller brush. With the high-speed rotation of the roller brush, the sewage is sucked into the sewage tank through another water channel through the vacuum suction channel behind the roller brush, thus completing the cleaning process.

[0101] The floor scrubber includes a handle assembly, a floor brush assembly, and a body. The body can be used to connect the handle assembly and the floor brush assembly. The floor brush assembly is located in front of the handle assembly. The floor brush assembly moves on the surface to be cleaned and can clean the surface to be cleaned through the roller brush. During the cleaning process of the floor scrubber, the handle assembly can reach the user's hand for the user to operate. The user can push and pull the handle assembly to control the cleaning direction of the floor brush assembly.

[0102] In the related art, the handle assembly has a single movement mode. The handle assembly can be flipped relative to the body or the handle assembly can be retracted. However, for tall users or when cleaning low spaces, the handle assembly is difficult to meet the comfort of use, affecting the user experience.

[0103] Based on the above technical problems, the applicant provides a handle assembly, which can realize the engagement or flipping of the handle body relative to the body through a folding mechanism. The telescopic mechanism can be used to control the inner tube to slide or lock relative to the outer tube, so that the handle assembly can be flipped relative to the body, and the telescopic movement of the handle assembly can be realized, thereby satisfying the comfort of users of different heights and the comfort of use in different application scenarios.

[0104] In addition, the applicant found that since both the folding trigger member and the telescopic trigger member are located on the handle, when the user triggers one of the folding trigger member and the telescopic trigger member, it is easy to touch the operating part of the other one, so that the folding trigger member and the telescopic trigger member are triggered at the same time, thereby causing the movement of the handle body to malfunction and affecting the normal operation of the cleaning device.

[0105] It is easy to understand that when the folding trigger member and the telescopic trigger member are triggered at the same time, the flipping movement of the handle body relative to the fuselage and the telescopic movement of the handle body move simultaneously, which can easily make it difficult for the user to control the movement of the handle body to the target state and is difficult to operate.

[0106] Therefore, an embodiment of the present application provides a handle assembly, which, by setting the non-operating end of the folding trigger member and the non-operating end of the telescopic trigger member to have a locked state, can prevent the folding trigger member from being triggered when the telescopic trigger member is triggered, thereby maintaining the flipping movement of the handle body relative to the fuselage and the telescopic movement of the handle body without interfering with each other, thereby improving the reliability of the handle body state adjustment.

[0107] The embodiments of the present application can meet the usage requirements of users of different heights and are also applicable to different application scenarios, which is beneficial to improving the user experience.

[0108] It should be noted that in the embodiments of the present application, the cleaning device can clean low spaces or low usage scenarios. For example, under the bed, under the sofa, under the table, etc.

[0109] See Figures 1 to 4 , which exemplarily shows four application scenarios of the cleaning device, and the application scenarios of the cleaning device are not limited to these four scenarios.

[0110] Figure 1 An exemplary structural diagram of the handle assembly 100 in the retracted state is shown. When the body is in the upright state, the body and the handle assembly 100 can tend to be collinear. In other words, the angle between the body and the handle assembly 100 is a flat angle. At this time, the body and the surface to be cleaned can be approximately perpendicular. For example, the angle between the body and the surface to be cleaned can be between 70° and 90°. The user can comfortably hold the handle assembly 100 to clean the surface to be cleaned in a spacious space. The application scenario where the body is in the upright state can be that the cleaning device is located on a base or pedestal. For example, the cleaning device can stand vertically on the base or base station for cleaning or charging the cleaning device. Among them, the handle assembly 100, the body, and the surface to be cleaned can all be kept vertical to save the space occupied by the cleaning device.

[0111] Figure 2 An exemplary structural diagram of the handle assembly 100 in the extended state is 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 tube 111, the length of the handle assembly 100 can be adjusted, thereby adjusting the height of the gripping end of the handle assembly 100 so that users of different heights can comfortably use the cleaning device.

[0112] In some examples, Figure 1 The state of the handle assembly 100 shown can be the initial state. At this time, the handle assembly 100 is not flipped relative to the body, and the handle assembly 100 can be in the non-extended state to facilitate the transportation and storage of the cleaning device.

[0113] Or, Figure 2The state of the handle assembly 100 shown may be an initial state. At this time, the handle assembly 100 is not flipped relative to the body, and the handle assembly 100 is extended for a certain distance. For example, the user can adjust the handle assembly 100 according to the height. In the initial state, the handle assembly 100 is extended for a certain distance, so that when the same user performs subsequent cleaning operations, it is not necessary to adjust the length of the handle assembly 100 each time. The user only needs to adjust the handle assembly 100 to flip relative to the body when encountering different low spaces.

[0114] 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 implementation of the present application.

[0115] Figure 3 The schematic diagram of the structure of the handle assembly 100 in a folded state is exemplarily shown. At this time, the cleaning device can be used to clean the surface to be cleaned in a low space. The body and the surface to be cleaned can be leveled so that the body can be in a flat state, so that the brush assembly can easily enter the low space for cleaning.

[0116] It should be noted that when the body is in a flat state, the body and the surface to be cleaned may be substantially parallel. For example, the angle between the body and the surface to be cleaned may be between 0° and 10°.

[0117] Figure 4 The schematic diagram of the structure of the handle assembly 100 in a folded and retracted state is exemplarily shown. For example, when cleaning a surface to be cleaned in a low space, the handle assembly 100 is folded relative to the body. The height of the gripping end of the handle assembly 100 relative to the surface to be cleaned is lowered, and the user needs to bend over to hold the handle assembly 100. At this time, the handle assembly 100 can be stretched to increase the height of the gripping end of the handle assembly 100 relative to the surface to be cleaned, so that the user can clean the surface to be cleaned in the low space without bending over.

[0118] The handle assembly 100, cleaning device, and cleaning system provided in the present application are described below with reference to the accompanying drawings and in combination with specific embodiments.

[0119] See also Figures 5 to 11 As shown, the handle assembly 100 according to the embodiment of the present application is applied to a cleaning device and may include a handle body 110 , a folding mechanism 120 and a locking member 130 .

[0120] The handle body 110 is directly or indirectly connected to the body of the cleaning device. The handle body 110 can be turned over relative to the body. The handle body 110 includes an outer sleeve 111 and an inner tube 112. The inner tube 112 can be slidably connected to the outer sleeve 111.

[0121] The folding mechanism 120 is located in the handle body 110. The folding mechanism 120 includes 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 fuselage. The traction assembly has a fixed length mode and a telescopic mode.

[0122] The locking member 130 moves in the handle body 110 to switch between the fixed length mode and the telescopic mode of the traction assembly. When the traction assembly is in the fixed length mode, the handle body 110 can be flipped relative to the body. When the traction assembly is in the telescopic mode, the inner tube 112 can slide relative to the outer tube 111 to achieve the telescopic operation of the handle body 110.

[0123] It should be noted that the fixed length mode of the traction assembly means that the internal structures of the traction assembly move synchronously, so that the overall length of the traction assembly can remain unchanged during the movement. The telescopic mode of the traction assembly means that the internal structures of the traction assembly move relative to each other, so that the overall length of the traction assembly changes. The overall length of the traction assembly can be extended or shortened.

[0124] In the embodiment of the present application, by setting a locking piece 130, the traction assembly can have a fixed-length mode and a telescopic mode, the handle body 110 can be flipped relative to the body, and the length of the handle body 110 can be adjusted, which can meet the comfort of users of different heights and different application scenarios.

[0125] When the traction assembly is in the fixed-length mode, the handle body 110 can be flipped relative to the body so that the body can be in a flat state, and the floor brush assembly can penetrate into a low space to clean the low space.

[0126] When the traction assembly is in the telescopic mode, the inner tube 112 of the handle body 110 can slide relative to the outer tube 111. By adjusting the length of the inner tube 112 extending relative to the outer tube 111, the length of the handle assembly 100 can be adjusted, so as to meet the use requirements of users of different heights and different application scenarios. For example, when the body is in an upright state, for users of short height, the inner tube 112 can be adjusted to extend from the outer tube 111 to a shorter length, or the inner tube 112 can be adjusted not to extend from the outer tube 111. For users of tall height, the inner tube 112 can be adjusted to extend longer from the outer tube 111 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 of tall height.

[0127] Moreover, when the body is in a lying flat state, the height of the holding end of the handle assembly 100 is reduced. Especially for users with a tall stature, the inner tube 112 can be adjusted to extend a longer dimension out of the outer tube 111, so that the height of the holding end of the handle assembly 100 is increased. As a result, the user does not need to bend down or squat to operate the handle assembly 100, which is beneficial to improving the use comfort of the cleaning device when cleaning low spaces.

[0128] In some examples, the handle body 110 is directly or indirectly connected to the body of the cleaning device. Among them, the handle body 110 can be directly rotatably connected to the body, or the handle body 110 can be connected to the body through the adapter rod 160. This is not limited in the embodiments of the present application.

[0129] Exemplarily, referring to Figures 1 to 4 As shown, when the handle body 110 is connected to the body through the adapter rod 160, the handle body 110 and the adapter rod 160 can be rotatably connected through the rotating shaft 180. The adapter rod 160 and the body can be fixedly connected by, but not limited to, a clamping method.

[0130] In some examples, the holding end of the handle assembly 100 can be provided with an operation key 102. Among them, the operation key 102 can be a physical button or a touch button, which is not limited in this embodiment. A control module can be provided inside the floor brush assembly to control the cleaning mode of the cleaning device. The operation key 102 and the control module can be electrically connected through the conductive cable 190, so that when the user triggers the operation key 102, the floor brush assembly can be controlled to be in different cleaning modes.

[0131] Among them, a space for accommodating the conductive cable 190 is provided inside the handle assembly 100. A terminal block can be provided at the end of the handle assembly 100 for connecting to the body. The terminal block is electrically connected to the conductive cable 190. The terminal block can be plugged into the body to electrically connect the conductive cable 190 to the control module through the terminal block.

[0132] In some examples, when the cleaning device is moving on a horizontal surface to be cleaned, the handle body 110 can be flipped relative to the body in a vertical plane. The axial direction of the rotating shaft 180 is perpendicular to the vertical plane.

[0133] In some examples, the outer tube 111 can be sleeved outside at least a part of the inner tube 112. Since the inner tube 112 is slidably connected to the outer tube 111, when the dimension of the inner tube 112 extending out of the outer tube 111 is larger, the overall length of the handle body 110 is larger. Among them, the axial directions of the inner tube 112 and the outer tube 111 can be the same. The sliding direction of the inner tube 112 and the outer tube 111 can be the same as the axial direction of the inner tube 112.

[0134] In some examples, the external force applied to the folding trigger 121 can come from the hand holding the handle body 110. In other words, an external force can be applied to the folding trigger 121 while holding the handle body 110 with one hand, so that the handle body 110 can be flipped relative to the body with one - hand operation, thereby adjusting the switching of the body between the lying - flat state and the upright state. During this process, two - hand operation is not required, and the operation is fast and convenient, which is beneficial to improving the user experience.

[0135] In some examples, the outer sleeve 111 and the inner tube 112 can be, but are not limited to, round tubes, square tubes, etc.

[0136] An embodiment of the present application provides another handle assembly 100. The handle assembly 100 may include a handle body 110, a folding mechanism 120, and a locking member 130.

[0137] 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, and the inner tube 112 is slidably connected to the outer sleeve 111.

[0138] The folding mechanism 120 is located inside the handle body 110. The folding mechanism 120 may include a folding trigger 121, a traction assembly, and an unlocking member 123. The folding trigger 121 drives the unlocking member 123 through the traction assembly to flip the handle body 110 relative to the body; the traction assembly has a fixed - length mode and a telescopic mode.

[0139] The locking member 130 moves inside the handle body 110 to have a locking position and a disengaging position. Among them, when the locking member 130 is in the locking position, the traction assembly is in the fixed - length mode, and the handle body 110 can be flipped relative to the body. When the locking member 130 is in the disengaging position, the traction assembly is in the telescopic mode, and the inner tube 112 can slide relative to the outer sleeve 111 to achieve the telescoping of the handle body 110.

[0140] In an embodiment of the present application, the locking member 130 is used to switch the traction assembly between the fixed - length mode and the telescopic mode. By switching the locking member 130 between the locking position and the disengaging position, the switching of the traction assembly between the fixed - length mode and the telescopic mode can be achieved.

[0141] Specifically, when the locking member 130 is in the locked position, it can lock the internal structure of the traction assembly, 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 123 to move, so that the handle body 110 can be flipped relative to the fuselage. When the locking member 130 is in the disengaged position, the locking between the internal structures of the traction assembly can be released, and relative movement can occur between the internal structures of the traction assembly, so that the overall length of the traction assembly can be extended or contracted. Thus, through the extension or contraction of the traction assembly, the inner tube 112 can slide relative to the outer tube 111, so that the length of the handle body 110 can be adjusted.

[0142] It should be noted that when the locking member 130 is in the locked position, the traction assembly corresponds to the fixed-length mode. Therefore, it is difficult to achieve the sliding of the inner tube 112 relative to the outer tube 111. Similarly, when the locking member 130 is in the disengaged position, the traction assembly corresponds to the telescopic mode. Therefore, it is difficult to achieve the flipping of the handle body 110 relative to the fuselage.

[0143] Therefore, by setting the locking member 130 to have a locked position and a disengaged position, the flipping movement of the handle body 110 relative to the fuselage and the sliding movement of the inner tube 112 of the handle body 110 relative to the outer tube 111 can be made independent of each other. When the handle body 110 is flipped relative to the fuselage, 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 flipping angle of the handle body 110 relative to the fuselage 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.

[0144] Similarly, when the inner tube 112 and the outer tube 111 are sliding relative to each other, the flipping angle of the handle body 110 relative to the fuselage can be kept fixed, and the flipping angle of the handle body 110 relative to the fuselage cannot be adjusted. After the sliding distance between the inner tube 112 and the outer tube 111 is adjusted, the flipping angle of the handle body 110 relative to the fuselage can be adjusted.

[0145] Such a setting can facilitate the user's control of the handle body 110 and avoid the possibility of the flipping action and the telescoping action being carried out simultaneously, resulting in the complication of the control of the handle body 110.

[0146] In some implementable ways, referring to Figure 8 and Figure 9 as shown, the traction assembly of the embodiment of the present application may include a first traction main body 1221 and a linkage member 1222. The first traction main body 1221 is connected to the unlocking member 123, and the linkage member 1222 is connected to the folding trigger member 121.

[0147] The locking member 130 locks the first traction main body 1221 and the linkage member 1222, so that the first traction main body 1221 and the linkage member 1222 move synchronously, and the traction assembly is in the fixed-length mode. The locking member 130 unlocks the first traction main body 1221 and the linkage member 1222, so that the first traction main body 1221 slides relative to the linkage member 1222. The traction assembly is in the telescopic mode.

[0148] In the embodiment of the present application, there are two motion states between the first traction main body 1221 and the linkage member 1222, corresponding to the fixed-length mode and the telescopic mode of the traction assembly respectively. Among them, when the locking member 130 is in the locking position, the first traction main body 1221 and the linkage member 1222 are locked by the locking member 130. The first traction main 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 main body 1221 and the linkage member 1222 can be jointly used to drive the unlocking member 123 to move, so as to realize the flipping of the handle main body 110 relative to the fuselage.

[0149] When the locking member 130 is in the disengaged position, the locking member 130 can unlock the first traction main body 1221 and the linkage member 1222. The first traction main body 1221 and the linkage member 1222 can slide relative to each other. One of the first traction main body 1221 and the linkage member 1222 can be used to make the inner tube 112 slide relative to the outer tube 111. Since the first traction main body 1221 is connected to the unlocking member 123, the movement of the first traction main body 1221 will cause the unlocking member 123 to move and affect the relative position between the handle main body 110 and the fuselage. Therefore, the relative sliding of the inner tube 112 and the outer tube 111 can be achieved by the movement of the linkage member 1222. In other words, the first traction main body 1221 can remain stationary relative to the handle main body 110, and the linkage member 1222 slides relative to the first traction main body 1221 to be used for the relative sliding of the inner tube 112 and the outer tube 111.

[0150] In some examples, the linkage member 1222 can be sleeved outside at least part of the first traction main body 1221. One end of the first traction main body 1221 can extend outside the linkage member 1222 to be used for driving the unlocking member 123 to move.

[0151] In some examples, the relative sliding direction of the first traction main body 1221 and the linkage member 1222 can be the axial movement along the inner tube 112. In other words, the relative sliding direction of the first traction main body 1221 and the linkage member 1222 is the same as the relative sliding direction of the inner tube 112 and the outer tube 111, so that the movement of the linkage member 1222 can directly act on the inner tube 112, reducing the complexity of the internal structure of the handle assembly 100.

[0152] In some implementable ways, refer to Figure 8 and Figure 9 As shown, at least part of the first traction body 1221 of the embodiment of the present application is located inside the linkage member 1222. The first traction body 1221 is provided with a mating groove 1221a that can accommodate at least part of the locking member 130. The linkage member 1222 is provided with a locking hole 122a through which the locking member 130 can pass.

[0153] When the traction assembly is in the fixed-length mode, the mating groove 1221a and the locking hole 122a can correspond to each other. The locking member 130 is located in the mating groove 1221a and the locking hole 122a. When the traction assembly is in the telescopic mode, the mating groove 1221a and the locking hole 122a can be arranged in a staggered manner. The locking member 130 is separated from the first traction body 1221.

[0154] In the embodiment of the present application, by the mutual cooperation of the locking member 130 with the mating groove 1221a and the locking hole 122a, the locking member 130 can be switched between the locking position and the disengaging position. With such a setting, the switching between the fixed-length mode and the telescopic mode of the traction assembly can be realized through a simple structure.

[0155] Specifically, the locking member 130 can move within the inner tube 112. When the mating groove 1221a and the locking hole 122a correspond to each other, at least part of the locking member 130 can be located in the mating groove 1221a and the locking groove. The locking member 130 can lock the first traction body 1221 and the linkage member 1222 to restrict relative sliding between the first traction body 1221 and the linkage member 1222, so that the first traction body 1221 and the linkage member 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 by the first traction body 1221 to flip the handle body 110 relative to the fuselage.

[0156] When the mating groove 1221a and the locking hole 122a are arranged in a staggered manner along the movement direction of the first traction body 1221 relative to the linkage member 1222, the locking member 130 can disengage from the mating groove 1221a. In other words, there is no contact between the locking member 130 and the first traction body 1221. At this time, part of the locking member 130 can be located in the locking hole 122a of the linkage member 1222, and the locking member 130 is in contact with the linkage member 1222. The locking member 130 and the linkage member 1222 can move synchronously, so that the linkage member 1222 can slide relative to the first traction body 1221.

[0157] In some examples, the relative movement direction of the first traction body 1221 and the linkage member 1222 is the axis of the inner tube 112. When the locking member 130 disengages from the mating groove 1221a to be in the disengaging position, the traction assembly is in the telescopic mode. CombiningFigure 8 and Figure 9 In the direction shown, when the linkage member 1222 moves to the right (away from the fuselage), the overall length of the traction assembly can increase to increase the overall length of the handle body 110. After the overall length of the handle body 110 increases, when it is necessary to reduce the length of the handle body 110, the linkage member 1222 can be moved to the left (towards the fuselage) so that the overall length of the traction assembly can be reduced, thereby meeting the usage comfort of users of different heights and different application scenarios.

[0158] It should be noted that since the locking member 130 is disengaged from the mating groove 1221a of the first traction body 1221, when the linkage member 1222 moves, the first traction body 1221 can remain stationary, thus not affecting the movement state of the unlocking member 123, and further the handle body 110 will not flip relative to the fuselage.

[0159] In some examples, the surfaces of the locking member 130 and the mating groove 1221a that cooperate with each other can be arc surfaces to improve the smoothness of the switching of the locking member 130 between the locked position and the disengaged position. Also, the force for driving the movement of the locking member 130 can be reduced, and the possibility of requiring a large driving force during the movement of the locking member 130, resulting in laboriousness, can be reduced.

[0160] 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.

[0161] Exemplarily, the locking member 130 can be a cylindrical structure. The mating groove 1221a can be a semi-cylindrical groove structure. Among them, the semi-cylindrical groove structure refers to an incomplete cylindrical structure.

[0162] In some implementable ways, referring to Figures 8 to 11 shown, the handle assembly 100 of the embodiment of the present application can further include a telescopic mechanism 140. At least a part of the telescopic mechanism 140 moves within the inner tube 112. The telescopic mechanism 140 can be provided with a limiting groove 140a that can accommodate at least a 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, and 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.

[0163] In the embodiment of the present application, by providing the limiting groove 140a that can accommodate at least a part of the locking member 130 on the telescopic mechanism 140, the limiting groove 140a can provide a 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.

[0164] Among them, the telescopic mechanism 140 can move within the inner tube 112. When the limiting groove 140a on the telescopic mechanism 140 corresponds to the locking hole 122a on the linkage member 1222, the locking member 130 can disengage from the mating groove 1221a and fall into the mating groove 1221a through the locking hole 122a on the linkage member 1222. At this time, the linkage member 1222 can move relative to the first traction main body 1221, so that the traction assembly is in the telescopic mode.

[0165] When the traction assembly is in the telescopic mode, the locking member 130 can be located in the locking hole 122a and the limiting groove 140a, so that the linkage member 1222 and the telescopic mechanism 140 can operate synchronously. The linkage member 1222 moves along the axial direction of the inner tube 112 to adjust the distance that the inner tube 112 extends relative to the outer sleeve 111, thereby adjusting the overall length of the handle main body 110.

[0166] Therefore, the associated movement of the folding mechanism 120 and the telescopic mechanism 140 can be realized through the linkage member 1222, and the folding mechanism 120 and the telescopic mechanism 140 can not interfere with each other. When the locking member 130 is in the locked position, the traction assembly is in the fixed-length mode, and the linkage member 1222 and the first traction main body 1221 can be jointly used to drive the unlocking member 123 to move, so as to realize the flipping of the handle main body 110 relative to the fuselage. When the locking member 130 is in the disengaged position, the traction assembly is in the telescopic mode, the linkage member 1222 can move relative to the first traction main body 1221, and the linkage member 1222 can move synchronously with the telescopic mechanism 140 to realize the adjustment of the overall length of the handle main body 110.

[0167] In some examples, the surfaces of the limiting groove 140a and the locking member 130 that cooperate with each other can be arc surfaces to improve the smoothness of the switching of the locking member 130 between the locked position and the disengaged position. Exemplarily, the locking member 130 can be a cylindrical structure. The limiting groove 140a can be a semi-cylindrical groove structure.

[0168] In some examples, the shape of the locking hole 122a can match the shape of the locking member 130. Among them, during the switching of the locking member 130 between the locked position and the disengaged position, the locking member 130 can remain located in the locking hole 122a.

[0169] In some examples, the linkage member 1222 can be but is not limited to a sleeve structure. For example, the linkage member 1222 can be a square sleeve. Since the linkage member 1222 is sleeved outside at least part of the first traction main body 1221, the first traction main body 1221 can be a square rod structure.

[0170] In some realizable ways, see Figure 8As shown, the locking hole 122a of the embodiment of the present application can be provided on the side wall of the linkage member 1222 close to the telescopic mechanism 140. When the traction assembly is in the fixed-length mode, along the extending direction of the side wall, the center of the side wall is aligned with the locking member 130.

[0171] In the embodiment of the present application, during the process of the locking member 130 switching from the locking position to the disengaging position, when the telescopic mechanism 140 moves so that the limiting groove 140a corresponds to the locking hole 122a and the mating groove 1221a, by setting the center of the side wall of the linkage member 1222 to be aligned with the locking member 130 in the extending direction of the side wall, it can facilitate the switching of the locking member 130 from the locking position to the disengaging position.

[0172] Specifically, referring to Figures 8 to 11 the direction shown, when the telescopic mechanism 140 moves to make the limiting groove 140a correspond to the locking hole 122a and the mating groove 1221a, on the one hand, the locking member 130 can fall downward into the limiting groove 140a under the action of its own gravity. The locking member 130 can be disengaged from the mating 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 mating groove 1221a of the first traction main body 1221, the linkage member 1222 can apply a rightward acting force to the locking member 130, and this rightward acting force passes through the center of the locking member 130. At the same time, the limiting groove 140a and the mating surface close to the right side can apply a leftward acting force to the locking member 130, and the limiting groove 140a applies an eccentric acting force to the locking member 130. Therefore, under the action of the linkage member 1222 and the mating surface of the mating groove 1221a of the first traction main body 1221, the locking member 130 can be driven to switch from the mating groove 1221a to the limiting groove 140a, so that the locking member 130 is switched from the locking position to the disengaging position, and thus the traction assembly is switched from the fixed-length mode to the telescopic mode.

[0173] In some examples, the mating groove 1221a can be provided with a mating surface having a guiding function. The mating surface on the mating groove 1221a can be a rounded corner or chamfer structure.

[0174] 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. And, 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 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 disengaging position, the locking member 130 can fall into the limiting groove 140a under the action of its own gravity.

[0175] When the locking member 130 switches from the disengaging position to the locking position, referring to Figures 8 to 11In the direction shown, the limiting groove 140a of the telescopic mechanism 140 is first made to correspond to the limiting groove 140a of the first traction body 1221, and then the telescopic mechanism 140 can be reset to the right. At this time, the telescopic mechanism 140 can apply a rightward force to the locking member 130. The matching surface of the limiting groove 140a and the left side of the locking member 130 can apply an oblique upward force to the locking member 130, so as to squeeze the locking member 130 from the limiting groove 140a into the matching groove 1221a, so that the locking member 130 is switched from the disengaged position to the locked position, so that the traction assembly is switched from the telescopic mode to the fixed length mode.

[0176] In some examples, the limiting groove 140a may be provided with a matching surface for guiding. The matching surface on the limiting groove 140a may be a rounded or chamfered structure.

[0177] In some examples, the matching groove 1221a can be provided on the surface of the first traction body 1221 facing the telescopic mechanism 140. The locking hole 122a can be provided on the inner wall of the linkage member 1222 near the matching groove 1221a. The limiting groove 140a can be provided on the surface of the telescopic mechanism 140 facing the folding mechanism 120.

[0178] In some possible implementations, see Figure 8 and Figure 9 As shown, one end of the unlocking member 123 of the embodiment of the present application is rotatably connected to the handle body 110, and the other end of the unlocking member 123 is rotatably connected to the first traction body 1221. When the traction assembly is in the fixed length mode, the unlocking member 123 moves to unlock the body directly or indirectly, and the handle body 110 can be flipped relative to the body.

[0179] It should be noted that when the handle body 110 is connected to the body through the adapter rod 160, since the body is fixedly connected to the adapter rod 160, the indirect unlocking of the unlocking member 123 and the body means that the unlocking member 123 is unlocked from the body by unlocking the adapter rod 160.

[0180] In the embodiment of the present application, taking the example of the handle body 110 and the body being connected via the transfer rod 160, when cleaning the surface to be cleaned in a spacious space, the unlocking member 123 and the transfer rod 160 can be in a locked state so that the body is in an upright state. When it is necessary to clean a low space, the locking member 130 is first moved to put the traction assembly in a fixed length mode. At this time, the first traction body 1221 can drive the unlocking member 123 to move so that the unlocking member 123 can be unlocked from the transfer rod 160, and the handle body 110 can be flipped relative to the transfer rod 160, so that the body can be adjusted to be in a lying state for cleaning a low space.

[0181] In some examples, the adapter rod 160 can be detachably connected to the body. The handle assembly 100 can be detached from the body through the adapter rod 160 to facilitate the transportation or storage of the cleaning device.

[0182] In some implementable ways, when the handle body 110 is connected to the body through the adapter rod 160, a locking groove can be provided on the adapter rod 160. When a part of the unlocking member 123 is located in the locking groove, the locking groove can restrict the movement of the unlocking member 123, so that the handle body 110 and the adapter rod 160 are relatively fixed. The handle body 110 cannot flip relative to the body.

[0183] Specifically, referring to Figure 9 the direction shown, when the traction assembly is in the fixed-length mode, driving the unlocking member 123 to rotate clockwise by the first traction body 1221 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 restricted by the locking groove, and thus the handle body 110 can flip relative to the adapter rod 160.

[0184] In some implementable ways, the folding mechanism 120 of the embodiment 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 member 121 is used to directly or indirectly unlock the unlocking member 123 from the body, and the handle body 110 can flip relative to the body. The unlocking elastic member is used to directly or indirectly lock the unlocking member 123 to the body.

[0185] Wherein, the direct unlocking or locking of the unlocking member 123 with the body means that when the handle body 110 is directly connected to the body, the unlocking member 123 can be directly unlocked or locked with the body. The indirect unlocking or locking of the unlocking member 123 with the body means that the handle body 110 is connected to the body through the adapter rod 160. The unlocking member 123 realizes unlocking or locking with the body by unlocking or locking with the adapter rod 160.

[0186] In the embodiment of the present application, the unlocking elastic member can be used to drive the unlocking member 123 to return into 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.

[0187] Specifically, when the traction assembly is in the fixed-length mode, during the process that the first traction main body 1221 drives the unlocking member 123 to rotate clockwise so that the unlocking member 123 disengages from the limiting groove 160a, the unlocking elastic member can undergo elastic deformation. In other words, when the first traction main body 1221 drives the unlocking member 123 to rotate, it needs to overcome the elastic force of the unlocking elastic member. Therefore, when the first traction main body 1221 releases the acting force on the unlocking member 123, the unlocking elastic member can release elastic potential energy to drive the unlocking elastic member to reset into the limiting groove 160a, so that the unlocking member 123 is locked with the limiting groove 160a, and the handle main body 110 cannot be flipped relative to the fuselage.

[0188] It should be noted that during the process that the handle main body 110 flips relative to the fuselage, under the elastic action of the unlocking elastic member, the part of the unlocking member 123 for cooperating with the limiting groove 160a can abut against the outer wall of the adapter rod 160. The unlocking elastic member can always apply a force to reset the unlocking member 123 into the limiting groove 160a.

[0189] In some examples, the unlocking elastic member can be but is not limited to a torsion spring.

[0190] In some implementable ways, the folding trigger member 121 slides relative to the handle main body 110 to trigger the unlocking of the unlocking member 123 from the fuselage directly or indirectly, and the handle main body 110 can be flipped relative to the fuselage.

[0191] The folding mechanism 120 can further include a trigger reset member 124. One end of the trigger reset member 124 is connected to the handle main body 110. The other end of the trigger reset member 124 is connected to the folding trigger member 121. The trigger reset member 124 is used to drive the folding trigger member 121 to reset, and the unlocking member 123 and the fuselage can be directly or indirectly locked.

[0192] In the embodiment of the present application, the user can operate the folding trigger member 121 to disengage the unlocking member 123 from the limiting groove 160a, so as to realize the flipping of the handle main body 110 relative to the fuselage. The fuselage can be switched to a lying state to clean low spaces. During the process that the unlocking member 123 disengages from the limiting groove 160a, the trigger reset member 124 can undergo deformation. In other words, when triggering the folding trigger member 121, it is necessary to overcome the acting force of the trigger reset member 124.

[0193] After the cleaning of the low - height space is completed, the unlocking elastic member and the trigger reset member 124 can be jointly used to drive the fuselage to switch from a lying state to an upright state or other states. At this time, the handle body 110 can be adjusted to flip relative to the fuselage first, so that the unlocking member 123 and the limiting groove 160a can correspond to each other. At this time, the unlocking elastic member can drive the unlocking member 123 to reset to the limiting groove 160a. The unlocking elastic member can drive the traction assembly to reset. And, the trigger reset member 124 can release the deformation force to drive the unlocking member 123 to reset into the limiting groove 160a.

[0194] In some examples, the movement direction of the folding trigger member 121 is the same as the relative movement direction of the first traction main body 1221 and the linkage member 1222.

[0195] In some realizable ways, referring to Figure 8 and Figure 9 as shown, the folding mechanism 120 may further include a second traction main body 1223. One end of the second traction main body 1223 is rotatably connected to the first traction main body 1221, and the other end of the second traction main body 1223 is rotatably connected to the unlocking member 123.

[0196] In the embodiment of the present application, by setting the two ends of the second traction main body 1223 to be rotatably connected to the first traction main body 1221 and the unlocking member 123 respectively, the rotational drive of the first traction main body 1221 on the unlocking member 123 can be realized.

[0197] In the embodiment of the present application, the first traction main body 1221 may be a rigid structure to be used to meet the relative sliding of the inner tube 112 and the outer tube 111, and has high movement reliability. By setting the second traction main body 1223 as a flexible structure, the acting force of the first traction main body 1221 moving along the axial direction of the inner tube 112 can be converted into the acting force for driving the unlocking member 123 to rotate. The structure of the first traction main body 1221 and the second traction main body 1223 cooperating in motion has the advantages of being stable and reliable, having a simple structure, and being small in volume.

[0198] Exemplarily, the first traction main body 1221 may be a rod - shaped structure. The second traction main body 1223 may be but is not limited to a rope.

[0199] In some realizable ways, referring to Figures 8 to 11 as shown, the telescopic mechanism 140 may further include a transmission assembly 141 and a lock pin assembly 142. The limiting groove 140a is arranged on the transmission assembly 141. The lock pin assembly 142 is connected to the transmission assembly 141. The transmission assembly 141 drives the lock pin assembly 142 to move to lock or unlock the length of the inner tube 112 extending out of the outer tube 111.

[0200] When at least a part of the locking member 130 is located in the fitting 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 tube 111. When at least a part of the 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 tube 111.

[0201] In the embodiment of the present application, since the limiting groove 140a is located on the transmission assembly 141, the movement of the transmission assembly 141 can cause the locking member 130 to switch between the locking position and the disengaging position. When the locking member 130 is located in the fitting 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 fuselage. At this time, the locking pin assembly 142 can be in a state of locking the inner tube 112 and the outer tube 111, so that no relative sliding occurs between the inner tube 112 and the outer tube 111. The length of the handle body 110 is not adjustable. When the locking member 130 is located in the limiting groove 140a, the traction assembly is in the telescopic mode, and the locking member 130 can lock the transmission assembly 141 and the linkage member 1222, and the transmission assembly 141 and the linkage member 1222 can move synchronously. At this time, the handle body 110 cannot be flipped relative to the fuselage. The movement of the transmission assembly 141 can cause the locking pin assembly 142 to unlock the limitation of the inner tube 112 and the outer tube 111, and the movement of the linkage member 1222 can cause relative movement between the inner tube 112 and the outer tube 111, thereby adjusting the length of the handle body 110.

[0202] It is easy to understand that when the locking member 130 is located at the locking position, the locking pin assembly 142 can lock the inner tube 112 and the outer tube 111, and no relative sliding occurs between the inner tube 112 and the outer tube 111. When the locking member 130 is located at the disengaging position, the locking pin assembly 142 can unlock the inner tube 112 and the outer tube 111, and the length of the inner tube 112 extending out of the outer tube 111 is adjustable.

[0203] In some examples, the inner tube 112 may be provided with an avoidance hole 112a. The outer sleeve 111 may be provided with a plurality of gear adjustment holes 111a. When the locking pin assembly 142 corresponds to the avoidance hole 112a and the gear adjustment holes 111a, the locking pin assembly 142 may be inserted into the avoidance hole 112a and the gear adjustment holes 111a, so that the inner tube 112 and the outer sleeve 111 are locked to each other. There will be no relative sliding between the inner tube 112 and the outer sleeve 111. When the locking pin assembly 142 does not correspond to the gear adjustment holes 111a, the locking pin assembly 142 will not hinder the movement of the inner tube 112 relative to the outer sleeve 111, and the locking pin assembly 142 can move within the inner tube 112 so that when the length of the inner tube 112 extending out of the outer sleeve 111 meets the use comfort, the locking pin assembly 142 can be inserted into the corresponding gear adjustment holes 111a.

[0204] In some implementable ways, the telescopic mechanism 140 may further include a telescopic trigger 143. The telescopic trigger 143 may be located at an end of the handle body 110 away from the 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.

[0205] In the embodiment 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 disengaged position, and the traction assembly can be in the telescopic mode. Thus, through the synchronous movement of the linkage member 1222 and the transmission assembly 141, the locking pin assembly 142 adjusts the length of the inner tube 112 extending out of the outer sleeve 111.

[0206] The embodiment of the present application further provides a cleaning device, which may include a body and the handle assembly 100 in any of the above embodiments. The handle assembly 100 is connected to the body.

[0207] In some examples, the cleaning device may further include a clean water tank and a sewage tank. The clean water tank and the sewage tank may be provided on the floor brush assembly or on the body. Alternatively, one of the clean water tank and the sewage tank may be provided on the floor brush assembly, and the other may be provided on the body. It is not limited in the embodiment of the present application.

[0208] The embodiment of the present application further provides a cleaning system. The cleaning system may include a base or a base station. The cleaning device may be placed on the base or the base station.

[0209] In some examples, the base can be used to clean the roller brush and dry the roller brush to prevent the roller brush from being in a wet state for a long time, which may cause odor or bacteria.

[0210] In some examples, the base station may have a charging function. When the cleaning device is placed on the base station, the base station can be charged and automatically loaded and unloaded. The base and the base station may be separate structures, or the base and the base station may be an integrated structure, which is not limited in the embodiments of the present application.

[0211] See also Figures 8 to 11 As shown, the handle assembly 100 of the embodiment of the present application is applied to a cleaning device. The handle assembly 100 may include a handle body 110 , a locking member 130 , a folding mechanism 120 and a telescopic mechanism 140 .

[0212] 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 can be slidably connected to the outer sleeve 111. The locking member 130 can move in the handle body 110.

[0213] The folding mechanism 120 is disposed on the handle body 110. The folding mechanism 120 is provided with a matching groove 1221a that can accommodate at least part of the locking member 130. The folding mechanism 120 is used to achieve the locking or flipping of the handle body 110 relative to the body when the locking member 130 is located in the matching groove 1221a.

[0214] 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 that can accommodate at least part of the locking member 130. The transmission assembly 141 moves along the length direction of the outer sleeve 111 to drive the locking member 130 to switch in the matching groove 1221a or the limiting groove 140a.

[0215] When the locking member 130 enters the limiting groove 140 a , the inner tube 112 and the outer tube 111 are unlocked by the locking pin assembly 142 , so that the inner tube 112 can telescopically slide relative to the outer tube 111 .

[0216] It should be noted that the embodiment of the present application is described by taking the example that the handle body 110 is connected to the body of the cleaning device via the adapter rod 160 .

[0217] In the embodiments of the present application, the folding mechanism 120 and the telescopic mechanism 140 can be used to achieve the flipping of the handle main body 110 relative to the fuselage, and can also achieve the telescoping of the handle main body 110. Therefore, the handle main body 110 can be flipped relative to the fuselage, so that the fuselage is in a lying state to be applicable to the cleaning scenario of low spaces. And, the handle main body 110 can be telescoped to meet the usage comfort of users with different heights. In addition, after the handle main body 110 is flipped relative to the fuselage, the length of the handle main body 110 can be adjusted by the telescoping of the handle main body 110. Or, the length of the handle main body 110 can be adjusted by the telescoping of the handle main body 110 first, and then the handle main body 110 can be flipped relative to the fuselage. Therefore, the handle assembly 100 of the embodiments of the present application can meet the usage comfort of users with different heights and different application scenarios.

[0218] Specifically, the folding mechanism 120 can be used to achieve the clamping or flipping of the handle main body 110 relative to the fuselage. Among them, when the handle main body 110 is clamped to the fuselage, there is no flipping movement between the handle main body 110 and the fuselage. When the handle main body 110 can be flipped relative to the fuselage, the fuselage can be in a lying state for cleaning low spaces.

[0219] The telescopic mechanism 140 can be used to achieve the telescoping of the handle main body 110. Among them, when relative sliding can occur between the inner tube 112 and the outer tube 111, the telescoping of the handle main body 110 can be achieved through the relative sliding of the inner tube 112 and the outer tube 111 to achieve the adjustment of the length of the handle main body 110. When the inner tube 112 and the outer tube 111 are locked, the inner tube 112 and the outer tube 111 are relatively fixed, and the length of the handle main body 110 is fixed.

[0220] Among them, the lock pin assembly 142 can be used to control the relative sliding or relative fixation between the inner tube 112 and the outer tube 111.

[0221] In addition, by providing the locking member 130, the flipping movement of the handle main body 110 relative to the fuselage and the telescoping movement of the handle main body 110 can be carried out separately through the position of the locking member 130. In other words, during the process of the handle main body 110 flipping relative to the fuselage, the inner tube 112 and the outer tube 111 can be relatively fixed, and the length of the handle main body 110 cannot be adjusted. During the process of the relative sliding of the inner tube 112 and the outer tube 111, the flipping angle of the handle main body 110 relative to the fuselage can be kept fixed, and the flipping angle of the handle main body 110 relative to the fuselage cannot be adjusted.

[0222] With such a setting, it is convenient for the user to control the handle body 110, avoiding the phenomenon that the handle body 110 is difficult to operate due to the simultaneous flipping and telescoping movements of the handle body 110. Moreover, when the flipping and telescoping movements are carried out simultaneously, the flipping and telescoping movements interfere with each other, and faults are likely to occur, thus affecting the user experience.

[0223] In some implementable ways, referring to Figure 8 and Figure 9 As shown, when at least part of the locking member 130 is located in the fitting groove 1221a, the handle body 110 can be flipped relative to the fuselage, and the locking pin assembly 142 locks the inner tube 112 and the outer tube 111. When at least part of the locking member 130 is located in the limit groove 140a, the flipping movement of the handle body 110 relative to the fuselage is locked, and the locking pin assembly 142 unlocks the inner tube 112 and the outer tube 111.

[0224] In the embodiment of the present application, the movement of the locking member 130 in the handle body 110 cooperates with the locking pin assembly 142, so that the flipping movement and the telescoping movement of the handle body 110 can be carried out step by step.

[0225] Specifically, when at least part of the locking member 130 is located in the fitting groove 1221a, the folding mechanism 120 can move so that the handle body 110 can be engaged or flipped relative to the fuselage. At this time, by locking the inner tube 112 and the outer tube 111 with the locking pin assembly 142, the inner tube 112 and the outer tube 111 can be relatively fixed during the flipping of the handle body 110.

[0226] When at least part of the locking member 130 is located in the limit groove 140a, the inner tube 112 and the outer tube 111 can be unlocked by the locking pin assembly 142, so as to adjust the length of the handle body 110 through the relative sliding of the inner tube 112 and the outer tube 111. Moreover, at this time, the position of the locking member 130 can prevent the handle body 110 from flipping relative to the fuselage.

[0227] Therefore, after the flipping angle of the handle body 110 relative to the fuselage 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. Or, after the relative sliding distance between the inner tube 112 and the outer tube 111 is adjusted, the handle body 110 can be flipped relative to the fuselage. It is not limited in this embodiment.

[0228] In some implementable ways, referring to Figures 8 to 11 As shown, the transmission component 141 of the embodiment of the present application moves forward or backward in the inner tube 112 to drive the locking member 130 to switch between the limit groove 140a and the fitting groove 1221a.

[0229] In the embodiments of the present application, by the different movement directions of the transmission assembly 141 within the inner tube 112, it can be used to drive the locking member 130 to switch between the limiting groove 140a and the mating groove 1221a, so as to realize the switching between the flipping movement and the telescopic movement of the handle body 110.

[0230] In some examples, the transmission assembly 141 can move along the length direction of the outer sleeve 111. Wherein, the length direction of the outer sleeve 111 and the axial direction of the outer sleeve 111 can be the same direction.

[0231] 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 flat angle, so that the fuselage is in an upright state. The handle body 110 does not flip relative to the fuselage.

[0232] During the cleaning process of the cleaning device, there are many scenarios in low spaces. Therefore, in the initial state of the handle assembly 100, the locking member 130 can be set to be located in the mating groove 1221a, so as to facilitate the flipping of the handle body 110 relative to the fuselage at any time. Thus, when encountering various scenarios in low spaces, the handle body 110 can be quickly driven to flip relative to the fuselage.

[0233] It should be noted that the embodiments of the present application do not limit the telescopic state of the handle body 110 in the initial state of the handle assembly 100.

[0234] Referring to Figures 8 to 11 the direction shown, when the transmission assembly 141 moves to the left, the locking member 130 can be disengaged from the mating groove 1221a and enter the limiting groove 140a. At this time, the handle body 110 cannot perform a flipping movement. The locking pin assembly 142 can unlock the inner tube 112 and the outer sleeve 111 to adjust the length of the handle body 110. When the length adjustment of the handle body 110 is completed, the transmission assembly 141 can be reset to the right, so that the locking member 130 is disengaged from the limiting groove 140a and enters the mating groove 1221a. At this time, the handle body 110 cannot perform a telescopic movement.

[0235] The embodiments of the present application further provide a handle assembly 100, which is applied to a cleaning device. The handle assembly 100 may include a handle body 110, a folding mechanism 120 and a telescopic mechanism 140.

[0236] The handle body 110 is directly or indirectly connected to the fuselage of the cleaning device. The handle body 110 can be flipped relative to the fuselage, the inner tube 112 is slidably connected to the outer sleeve 111, and a plurality of gear adjustment holes 111a are provided on the outer sleeve 111.

[0237] The folding mechanism 120 can be used to achieve the engagement or flipping of the handle body 110 relative to the fuselage. The telescopic mechanism 140 includes a transmission assembly 141 and a locking pin assembly 142. The locking pin assembly 142 includes a locking pin body 1421. The transmission assembly 141 moves along the length direction of the outer sleeve 111 to drive the locking pin body 1421 to switch between the locked state and the unlocked state.

[0238] Wherein, when the locking pin body 1421 is in the locked state, the locking 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 locking pin body 1421 is in the unlocked state, the locking pin body 1421 disengages from the gear adjustment hole 111a, and the inner tube 112 can slide relative to the outer sleeve 111.

[0239] In the embodiment of the present application, a plurality of gear adjustment holes 111a are provided on the outer sleeve 111. When the locking pin body 1421 is inserted into any one of the gear adjustment holes 111a, the inner tube 112 can be fixed relative to the outer sleeve 111. When the locking pin body 1421 corresponds to different gear adjustment holes 111a, the handle body 110 can have different lengths.

[0240] When it is necessary to adjust the length of the handle body 110, the locking pin body 1421 can be first placed in the unlocked state so that the locking pin body 1421 can disengage from the original gear adjustment hole 111a. Since the inner tube 112 and the outer sleeve 111 can slide relative to each other when the locking pin body 1421 is in the unlocked state, by the relative sliding of the inner tube 112 and the outer sleeve 111, the locking pin body 1421 can correspond to the target gear adjustment hole 111a. The locking 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.

[0241] In some examples, the plurality of gear adjustment holes 111a can be arranged at intervals along the length direction of the outer sleeve 111.

[0242] In some examples, the embodiment of the present application does not limit the number of the gear adjustment holes 111a. For example, the number of the gear adjustment holes 111a can be three, four, five or even more.

[0243] In some examples, the embodiment of the present application does not limit the distance between two adjacent gear adjustment holes 111a. For example, the plurality of gear adjustment holes 111a can be evenly distributed on the outer sleeve 111. In other words, the distance between two adjacent gear adjustment holes 111a can be equal.

[0244] In some examples, the lock pin body 1421 may include a lock pin post. An avoidance hole 112a may be provided on the inner tube 112. The lock pin post and the avoidance hole 112a may correspond to each other. When the lock pin body 1421 is in the locked state, the lock pin post may 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 tube 111 may be fixed. When the lock pin body 1421 is in the unlocked state, the lock pin post and the gear adjustment hole 111a may be offset in the length direction of the outer tube 111, and the inner tube 112 and the outer tube 111 may slide relative to each other.

[0245] In some implementable ways, as shown in Figure 9 When the lock pin body 1421 of the embodiment of the present application is in the locked state, the handle body 110 can be flipped relative to the fuselage. When the lock pin body 1421 is in the unlocked state, the handle body 110 can be engaged with the fuselage.

[0246] In the embodiment of the present application, when the lock pin body 1421 is in the locked state, the lock pin body 1421 makes the inner tube 112 and the outer tube 111 relatively fixed, and the length of the handle body 110 remains fixed. At this time, the handle body 110 can be flipped relative to the fuselage for cleaning low spaces. When the lock pin body 1421 is in the unlocked state, relative sliding can occur between the inner tube 112 and the outer tube 111, and the handle body 110 can be telescopic. At this time, the handle body 110 can be engaged with the fuselage so that the handle body 110 does not perform a flipping motion, thereby realizing the non-interference between the flipping motion and the telescopic motion of the handle body 110.

[0247] In some implementable ways, as shown in Figures 8 to 11 The lock pin assembly 142 of the embodiment of the present application may include an adapter 1422. Part of the adapter 1422 may be connected to the transmission assembly 141. Part of the adapter 1422 may be connected to the lock pin body 1421. The adapter 1422 can move along the length direction of the outer tube 111. The adapter 1422 can drive the lock pin body 1421 to move axially along the gear adjustment hole 111a.

[0248] In the embodiment of the present application, the movement direction of the lock pin body 1421 is the same as the axial direction of the gear adjustment hole 111a. Since the gear adjustment hole 111a is provided on the outer tube 111, and the lock pin body 1421 can be inserted into the gear adjustment hole 111a through the lock pin post, the axial direction of the gear adjustment hole 111a can be perpendicular to the length direction of the outer tube 111.

[0249] By providing the adapter 1422, it can be used to transfer the acting force. The adapter 1422 can transfer the acting force of the transmission assembly 141 to the locking pin assembly 142. Moreover, the adapter 1422 can also be used to change the direction of the acting force. The adapter 1422 can convert the acting force of the transmission member along the length direction of the outer sleeve 111 into the acting force for the axial movement of the locking pin body 1421 along the gear shifting adjustment hole 111a.

[0250] By providing the adapter 1422 to cooperate with the transmission assembly 141 and the locking pin assembly 142 in motion, the transmission assembly 141 and the locking pin assembly 142 can be arranged side by side in the axial direction of the gear shifting adjustment hole 111a, which is beneficial to saving the space inside the inner tube 112 along the length direction of the outer sleeve 111 to simplify the internal structure.

[0251] In some implementable ways, refer to Figure 9 and Figure 11 As shown, the adapter 1422 of the embodiment of the present application can be provided with a first inclined transfer portion 1422a. The locking pin body 1421 can be provided with a second inclined transfer portion 1421a. The first inclined transfer portion 1422a and the second inclined transfer portion 1421a can cooperate in motion.

[0252] In the embodiment of the present application, the first inclined transfer portion 1422a is inclined with respect to the motion direction of the adapter 1422. The second inclined transfer portion 1421a cooperates with the first inclined transfer portion 1422a. Through the first inclined transfer portion 1422a and the second inclined transfer portion 1421a, the conversion of the acting force direction of the transmission assembly 141 can be realized.

[0253] Refer to Figures 8 to 11 As shown in the direction, when the transmission assembly 141 moves leftward along the length direction of the outer sleeve 111, the transmission assembly 141 can drive the adapter 1422 to move leftward. The first inclined transfer portion 1422a and the second inclined transfer portion 1421a cooperate in motion. The leftward movement of the adapter 1422 can provide an upward movement space for the locking pin body 1421. The locking pin body 1421 can move upward so that the locking pin column can be disengaged from the gear shifting adjustment hole 111a, and the inner tube 112 and the outer sleeve 111 can have relative sliding.

[0254] Correspondingly, when the transmission assembly 141 moves rightward along the length direction of the outer sleeve 111, the transmission assembly 141 can drive the adapter 1422 to move rightward. The rightward movement of the adapter 1422 can push the locking pin body 1421 downward to make the locking pin column inserted into the gear shifting adjustment hole 111a, and the inner tube 112 and the outer sleeve 111 are relatively fixed.

[0255] In some implementable ways, refer to Figure 8As shown, the locking pin assembly 142 of the embodiment of the present application may include a fixing member 1423. The fixing member 1423 may be disposed on the inner tube 112. A slideway 1423a for accommodating at least part of the adapter 1422 and at least part of the locking pin body 1421 is provided in the fixing member 1423. The slideway 1423a extends along the length direction of the outer sleeve 111.

[0256] The fixing member 1423 may be provided with a limiting chute 1423b. One of the adapter 1422 and the transmission assembly 141 may pass through the limiting chute 1423b to be connected to the other.

[0257] In the embodiment of the present application, by providing the fixing member 1423, a movement space can be provided for the adapter 1422. The slideway 1423a of the fixing member 1423 has a guiding effect on the movement direction of the adapter 1422.

[0258] Among them, the limiting chute 1423b can be used to connect the transmission assembly 141 and the adapter 1422, so that the adapter 1422 is driven to move by the movement of the transmission assembly 141. And the limiting chute 1423b can have a limiting effect on the adapter 1422 to restrict the movement range of the adapter 1422 in the length direction of the outer sleeve 111, which is beneficial to improving the matching reliability between the locking pin column and the gear adjustment hole 111a.

[0259] In some examples, part of the adapter 1422 may extend out of the limiting chute 1423b to be connected to the transmission assembly 141. Or, part of the transmission assembly 141 may extend into the interior of the slideway 1423a through the limiting chute 1423b to be connected to the adapter 1422, which is not limited in this embodiment.

[0260] In some realizable ways, refer to Figure 10 As shown, the telescopic mechanism 140 of the embodiment of the present application may further include a telescopic trigger 143. The telescopic trigger 143 is connected to the transmission assembly 141. The telescopic trigger 143 is used to drive the transmission assembly 141 to move.

[0261] Among them, when the telescopic trigger 143 is not triggered, the adapter 1422 drives the locking pin body 1421 to be inserted into the gear adjustment hole 111a. When the telescopic trigger 143 is triggered, the adapter 1422 can make the locking pin body 1421 disengage from the gear adjustment hole 111a.

[0262] In the embodiment of the present application, the telescopic trigger 143 can provide an operable structure for the user. By triggering the telescopic trigger 143, the user can switch the locking pin body 1421 between the locked state and the unlocked state.

[0263] When the current length of the handle body 110 can meet a relatively comfortable user experience, the telescopic trigger 143 may not be triggered. At this time, the locking pin column of the locking pin body 1421 is inserted into the gear adjustment hole 111a, and the inner tube 112 and the outer tube 111 are relatively fixed, and the length of the handle body 110 is fixed. When it is necessary to adjust the length of the handle body 110, the telescopic trigger 143 can be triggered. The telescopic trigger 143 can drive the transmission assembly 141 to move, so as to drive the adapter 1422 through the transmission assembly 141 to transmit the acting force to the locking pin body 1421. The locking pin column of the locking pin body 1421 can be disengaged from the gear adjustment hole 111a, so that the inner tube 112 and the outer tube 111 can slide relative to each other, thereby adjusting the length of the handle body 110.

[0264] 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 tube 111.

[0265] Specifically, referring to Figures 8 to 11 the direction shown, when the telescopic trigger 143 rotates counterclockwise, the transmission assembly 141 can apply a leftward acting force to the adapter 1422. The adapter 1422 moves leftward in the slideway 1423a, which can provide upward movement space for the first inclined adapter part 1422a for the locking pin body 1421. The locking pin body 1421 can move upward to disengage from the gear adjustment hole 111a. Correspondingly, when the telescopic trigger 143 is reset clockwise, the adapter 1422 moves rightward in the slideway 1423a. The first inclined adapter part 1422a can squeeze the locking pin body 1421 to move downward, so that when the locking pin body 1421 corresponds to the gear adjustment hole 111a, the locking pin column of the locking pin body 1421 can be inserted into the gear adjustment hole 111a.

[0266] In some realizable ways, referring to Figure 11 shown, the locking pin assembly 142 may further include a telescopic reset member 1424. One end of the telescopic reset member 1424 is connected to the fixing member 1423. The other end of the telescopic reset member 1424 is connected to the adapter 1422. The telescopic reset member 1424 can be used to drive the telescopic trigger 143 to reset to the untriggered state.

[0267] In the embodiment of the present application, referring to Figures 8 to 11In the shown direction, when the user triggers the telescopic trigger 143 and the telescopic trigger 143 rotates counterclockwise, the transmission assembly 141 can cause the adapter 1422 to move leftward. At this time, the telescopic return member 1424 can be deformed by the force of the adapter 1422. Since the adapter 1422 moves leftward, the locking pin column of the locking pin body 1421 can be disengaged from the gear position adjustment hole 111a. When the user cancels the force on the telescopic trigger 143, the leftward force of the transmission assembly 141 on the adapter 1422 is released. At this time, the telescopic return member 1424 can release the deformed force. On the one hand, it can drive the adapter 1422 to move rightward to drive the locking pin column of the locking pin body 1421 to insert into the gear position adjustment hole 111a through the adapter 1422. On the other hand, since the adapter 1422 is connected to the transmission assembly 141, the telescopic return member 1424 can drive the transmission assembly 141 to move rightward through the adapter 1422, so that the telescopic trigger 143 rotates clockwise to reset.

[0268] In some examples, the telescopic return member 1424 can be but is not limited to a spring.

[0269] In some implementable ways, referring to Figures 8 to 11 As shown, the locking pin assembly 142 can further include a locking pin return member 1425. Along the axial direction of the gear position adjustment hole 111a, one end of the locking pin return member 1425 is connected to the fixing member 1423, and the other end of the locking pin return member 1425 is connected to the locking pin body 1421. The locking pin return member 1425 can be used to drive the locking pin body 1421 to disengage from the gear position adjustment hole 111a when the telescopic trigger 143 is triggered.

[0270] In the embodiment of the present application, the locking pin return 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 return member 1425 can be deformed. When the adapter 1422 moves leftward, the downward force of the adapter 1422 on the locking pin body 1421 is released. At this time, the locking pin return member 1425 can release the deformed force so that the locking pin column of the locking pin body 1421 can be disengaged from the gear position adjustment hole 111a.

[0271] In some implementable ways, referring to Figure 8 As shown in FIGS. 11, the handle assembly 100 can further include a locking member 130. The transmission assembly 141 can drive the locking member 130 to move within the handle body 110. The folding mechanism 120 is provided with a mating groove 1221a. When the locking member 130 mates with the mating groove 1221a, the locking pin body 1421 is in the locked state. The telescopic mechanism 140 is provided with a limiting groove 140a. When the locking member 130 mates with the limiting groove 140a, the locking pin body 1421 is in the unlocked state.

[0272] In the embodiments of the present application, the locking member 130 switches between the fitting 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 flipping movement and the telescopic movement of the handle body 110 can be made independent of each other.

[0273] Specifically, when at least a part of the locking member 130 is located in the fitting groove 1221a, the folding mechanism 120 can move so that the handle body 110 can be engaged with or flipped relative to the fuselage. At this time, the locking pin assembly 142 is in the locked state. By locking the inner tube 112 and the outer tube 111 through the locking pin assembly 142, relative fixation between the inner tube 112 and the outer tube 111 can be achieved during the flipping of the handle body 110.

[0274] When at least a part of the locking member 130 is located in the limiting groove 140a, the locking pin assembly 142 is in the unlocked state. The inner tube 112 and the outer tube 111 can be unlocked through the locking pin assembly 142, so as to adjust the length of the handle body 110 by the relative sliding of the inner tube 112 and the outer tube 111. Moreover, the position of the locking member 130 can prevent the handle body 110 from flipping relative to the fuselage.

[0275] In some feasible ways, referring to Figure 10 As shown, the transmission assembly 141 may include a connecting rod 1411 and a slider 1412. One end of the connecting rod 1411 is connected to the slider 1412, and the other end of the connecting rod 1411 is connected to the telescopic trigger member 143.

[0276] The slider 1412 can be used to drive the adapter 1422 to move along the length direction of the outer tube 111, and the slider 1412 is used to drive the locking member 130 to switch between the folding mechanism 120 and the slider 1412.

[0277] In the embodiments of the present application, the connecting rod 1411 and the slider 1412 can be used to transmit the acting force, so that when the telescopic trigger member 143 is triggered, the adapter 1422 can be driven to move through the connecting rod 1411 and the slider 1412, so that the locking pin assembly 142 is in the locked state or the unlocked state. Among them, the combined movement of the connecting rod 1411 and the slider 1412 has the advantages of simple structure and high reliability.

[0278] In some examples, the connecting rod 1411 is rotatably connected to the telescopic trigger member 143. The connecting rod 1411 is rotatably connected to the slider 1412. The slider 1412 can move along the length direction of the outer tube 111.

[0279] In some feasible ways, referring to Figures 8 to 11As shown, the handle assembly 100 may further include a linkage member 1222. At least a part of the linkage member 1222 may be located inside the inner tube 112. An inner space is formed between the linkage member 1222 and the inner wall of the inner tube 112 for the transmission assembly 141 to move along the length direction of the outer tube 111.

[0280] In the embodiments of the present application, the linkage member 1222 and the locking member 130 may move synchronously. When the locking member 130 is located in the limiting groove 140a, the sliding of the linkage member 1222 can be used to achieve the relative sliding of the inner tube 112 and the outer tube 111. Moreover, an inner space having a guiding effect on the slider 1412 may be formed between the linkage member 1222 and the inner wall of the inner tube 112.

[0281] In some realizable ways, referring to Figures 8 to 11 As shown, the folding mechanism 120 may further include a first traction body 1221, and the first traction body 1221 is slidably connected to the linkage member 1222. A mating groove 1221a is provided on the first traction body 1221, and a locking hole 122a through which the locking member 130 can pass is provided on the linkage member 1222. When the locking member 130 is located in the locking hole 122a and the mating groove 1221a, the first traction body 1221 and the linkage member 1222 move synchronously, and the first traction body 1221 drives the handle body 110 to be engaged or flipped relative to the fuselage.

[0282] In some realizable ways, referring to Figure 2 As shown, the slider 1412 is provided with a limiting groove 140a. When the locking member 130 is located in the limiting groove 140a and the locking hole 122a, the transmission assembly 141 is used to adjust the extending length of the inner tube 112 relative to the outer tube 111.

[0283] The embodiments of the present application further provide a cleaning device. Referring to Figure 10 As shown, the cleaning device may include a fuselage and the handle assembly 100 in any of the above embodiments. The handle assembly 100 is connected to the fuselage.

[0284] In some examples, the cleaning device may further include a clean water tank and a sewage tank. The clean water tank and the sewage tank may be arranged on the floor brush assembly or on the fuselage. Alternatively, one of the clean water tank and the sewage tank may be arranged on the floor brush assembly, and the other may be arranged on the fuselage. It is not limited in the embodiments of the present application.

[0285] The embodiments of the present application further provide a cleaning system. The cleaning system may include a base or a base station. The cleaning device may be placed on the base or the base station.

[0286] In some examples, the base can be used to clean the roller brush and dry the roller brush to prevent the roller brush from being in a wet state for a long time, resulting in odor or bacteria.

[0287] In some examples, the base station may 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 drained. Wherein, the base and the base station may be a split structure, or the base and the base station may be an integral structure, which is not limited in the embodiments of the present application.

[0288] See Figure 10 As shown, the handle assembly 100 of the embodiment of the present application can be applied to a cleaning device. The handle assembly 100 may include a handle body 110, a folding mechanism 120, a locking member 130, and a telescopic mechanism 140.

[0289] 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 tube 111, and a plurality of gear adjustment holes 111a are provided on the outer tube 111 at intervals along its length direction.

[0290] The folding mechanism 120 can be arranged on the handle body 110. The folding mechanism 120 is provided with a plurality of mating grooves 1221a spaced at intervals along its length direction. The locking member 130 cooperates with the mating grooves 1221a to enable the folding mechanism 120 to drive the handle body 110 to be engaged or flipped relative to the body.

[0291] The telescopic mechanism 140 is arranged on the handle body 110. The telescopic mechanism 140 may include a locking pin assembly 142. The locking pin assembly 142 is inserted into or disengaged from the gear adjustment holes 111a to lock the outer tube 111 and the inner tube 112 or to realize the telescopic sliding of the inner tube 112 relative to the outer tube 111;

[0292] Wherein, the number of the gear adjustment holes 111a is less than or equal to the number of the mating grooves 1221a, and the distance between two adjacent gear adjustment holes 111a is equal to the distance between two adjacent mating grooves 1221a.

[0293] In the embodiments of the present application, a plurality of gear adjustment holes 111a are provided on the outer sleeve 111 at intervals along its own length direction. 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 sleeve 111, and the handle body 110 can achieve telescopic movement, so that the handle body 110 has different gear lengths. Since the locking member 130 and the mating groove 1221a cooperate with each other and can be used to drive the handle body 110 to engage or flip relative to the fuselage, 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 adjacent two gear adjustment holes 111a is equal to the distance between adjacent two mating grooves 1221a, when the handle body 110 corresponds to different gear lengths, the handle body 110 can be flipped relative to the fuselage, so that the flipping movement of the handle body 110 relative to the fuselage can be achieved, and the telescopic movement of the handle body 110 can also be achieved.

[0294] Specifically, taking the example that the number of gear adjustment holes 111a matches the number of mating grooves 1221a, the gear adjustment holes 111a and the mating grooves 1221a can correspond one by one. When the locking pin assembly 142 is inserted into one of the gear adjustment holes 111a so that the length of the handle body 110 can meet the use comfort, 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 fuselage.

[0295] When the locking pin assembly 142 moves to another gear adjustment hole 111a, it can make the locking member 130 just located in the corresponding mating groove 1221a, so that the handle body 110 can flip relative to the fuselage when the length of the handle body 110 is fixed.

[0296] Exemplarily, referring to Figures 8 to 11 the direction shown, four gear adjustment holes 111a can be provided in sequence from left to right. And four mating grooves 1221a can be provided in sequence from left to right. Among them, 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 in 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 in the second mating groove 1221a on the left. And so on, which will not be elaborated here.

[0297] It should be noted that the mating groove 1221a and the gear adjustment hole 111a can be staggeredly arranged along the length direction of the outer sleeve 111, or the mating groove 1221a and the gear adjustment hole 111a can be vertically corresponding with reference to Figures 8 to 11 the direction shown, which is not limited in this embodiment.

[0298] In some realizable ways, refer to Figure 8 As shown, when the locking pin assembly 142 of the embodiment of the present application is inserted into the gear adjustment hole 111a, the locking member 130 is located in the fitting groove 1221a.

[0299] In the embodiment of the present application, when the locking pin assembly 142 is inserted into the gear adjustment hole 111a, the inner tube 112 and the outer tube 111 are locked to each other. At this time, the locking member 130 is located in the fitting groove 1221a to drive the handle body 110 to engage or flip relative to the fuselage. Therefore, the movement of the handle body 110 engaging or flipping relative to the fuselage and the telescopic movement of the handle body 110 cannot be performed simultaneously. In other words, the movement of the handle body 110 engaging or flipping relative to the fuselage and the telescopic movement of the handle body 110 need to be operated step by step, which is beneficial to improving the reliability of the movement of the handle body 110 engaging or flipping relative to the fuselage and the telescopic movement of the handle body 110, and can facilitate the user to control the state of the handle body 110.

[0300] In some realizable ways, refer to Figure 10 As shown, the distribution direction of the gear adjustment hole 111a of the embodiment of the present application is parallel to the distribution direction of the fitting groove 1221a.

[0301] In the embodiment of the present application, by setting the distribution direction of the gear adjustment hole 111a to be parallel to the distribution direction of the fitting groove 1221a, when adjusting the sliding of the inner tube 112 relative to the outer tube 111 so that the locking pin assembly 142 is inserted into different gear adjustment holes 111a, it can be ensured that the locking member 130 is located in the corresponding fitting groove 1221a to avoid the possibility that the locking member 130 is offset or separated from the fitting groove 1221a, resulting in affecting the movement of the handle body 110 engaging or flipping relative to the fuselage.

[0302] In some realizable ways, refer to Figure 10 As shown, when the inner tube 112 telescopically slides relative to the outer tube 111, the locking pin assembly 142 slides past at least one gear adjustment hole 111a, and the locking member 130 correspondingly slides past the same number of fitting grooves 1221a.

[0303] In the embodiment of the present application, during the relative sliding of the inner tube 112 and the outer tube 111, setting the number of gear adjustment holes 111a passed by the locking pin assembly 142 to be equal to the number of fitting grooves 1221a correspondingly slid past by the locking member 130 can ensure that when the handle body 110 has different lengths in different gears, the handle body 110 can realize the engagement or flipping movement relative to the fuselage, and avoid the possibility that the locking member 130 enters the misaligned fitting groove 1221a, resulting in affecting the movement of the handle body 110 engaging or flipping relative to the fuselage, and even affecting the telescopic movement of the handle body 110.

[0304] It is easily understood that the distance by which the handle body 110 expands and contracts may be equal to the sum of the spacings of all the mating grooves 1221a that the locking member 130 slides across.

[0305] Exemplarily, with reference to Figures 8 to 11 the direction shown, when the number of mating grooves 1221a is the same as the number of gear adjustment holes 111a, when the lock pin assembly 142 moves from the leftmost first gear adjustment hole 111a to correspond to the leftmost third gear adjustment hole 111a, the locking member 130 moves from the leftmost first mating groove 1221a to the leftmost third mating groove 1221a.

[0306] In some implementable ways, referring to Figure 10 shown, the telescopic mechanism 140 of the embodiment of the present application may include a transmission assembly 141. The transmission assembly 141 may be provided with a limit groove 140a. The transmission assembly 141 moves along the length direction of the outer sleeve 111 to drive the locking member 130 to switch between the mating groove 1221a and the limit groove 140a.

[0307] The transmission assembly 141 is connected to the lock pin assembly 142. The transmission assembly 141 drives the lock pin assembly 142 to insert into or disengage from the gear adjustment hole 111a. Wherein, when the lock pin assembly 142 disengages from the gear adjustment hole 111a, the locking member 130 may be located in the limit groove 140a.

[0308] In the embodiment of the present application, the transmission assembly 141 can be used to drive the locking member 130 to switch between the mating groove 1221a and the limit groove 140a. When the locking member 130 is located in the mating groove 1221a, the lock pin assembly 142 locks the outer sleeve 111 and the inner tube 112 to fix the length of the handle body 110. At this time, the handle body 110 can be engaged with or flipped relative to the fuselage. When the locking member 130 is located in the limit groove 140a, the locking member 130 disengages from the mating groove 1221a, and the handle body 110 cannot be engaged with or flipped relative to the fuselage. The transmission assembly 141 can cause the lock pin assembly 142 to disengage from the gear adjustment hole 111a to achieve the telescopic sliding of the inner tube 112 relative to the outer sleeve 111.

[0309] Therefore, by setting the locking member 130 to switch between the mating groove 1221a and the limit groove 140a, the synchronous movement of the engaging or flipping movement of the handle body 110 relative to the fuselage and the telescopic sliding of the inner tube 112 relative to the outer sleeve 111 can be restricted. In other words, the engaging or flipping movement of the handle body 110 relative to the fuselage and the telescopic sliding of the inner tube 112 relative to the outer sleeve 111 need to be operated step by step.

[0310] In some examples, when the locking member 130 is located in the mating groove 1221a, the mating groove 1221a and the limiting groove 140a may be staggeredly arranged in the length direction of the outer sleeve 111 to prevent the locking member 130 from disengaging from the mating groove 1221a and falling into the limiting groove 140a.

[0311] In some implementable ways, as shown in Figures 8 to 11 shown, along the radial direction of the outer sleeve 111, the folding mechanism 120 and the telescopic mechanism 140 are arranged side by side. The opening directions of the mating groove 1221a and the limiting groove 140a are opposite to each other.

[0312] 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 can save the dimension of the inner tube 112 along its own length direction. The structures of the folding mechanism 120 and the telescopic mechanism 140 are compact, which is beneficial to realizing the compact and weight-reducing design of the cleaning device.

[0313] Among them, by setting the opening directions of the mating groove 1221a and the limiting groove 140a to be opposite to each other, it is convenient for the locking member 130 to switch between the two.

[0314] In some implementable ways, as shown in Figure 10 shown, the folding mechanism 120 may include a first traction main body 1221 and a linkage member 1222. The first traction main body 1221 is slidably connected to the linkage member 1222. The first traction main body 1221 is provided with a mating groove 1221a, and the linkage member 1222 is provided with a locking hole 122a. When the locking pin assembly 142 is inserted into the gear position adjusting hole 111a, the locking member 130 is located in the locking hole 122a and one of the mating grooves 1221a. The first traction main body 1221 is used to drive the handle main body 110 to be clamped or rotated relative to the fuselage.

[0315] In the embodiments of the present application, when the locking member 130 is located in the locking hole 122a and one of the mating grooves 1221a, the locking member 130 can lock the first traction main body 1221 and the linkage member 1222 to each other. The first traction main body 1221 and the linkage member 1222 can move synchronously, so that the handle main body 110 can be clamped or flipped relative to the fuselage through the first traction main body 1221. At this time, since the locking pin assembly 142 is inserted into the gear position adjusting hole 111a, the outer sleeve 111 and the inner tube 112 can be locked to each other, and the length of the handle main body 110 cannot be adjusted.

[0316] In some implementable ways, as shown in Figures 8 to 11As shown, the transmission component 141 of the embodiment of the present application may include a slider 1412 for driving the lock pin component 142. The slider 1412 may be provided with a limit groove 140a. When the lock pin component 142 disengages from the gear adjustment hole 111a, the locking hole 122a corresponds to the limit groove 140a. The locking member 130 is located in the locking hole 122a and the limit groove 140a.

[0317] In the embodiment of the present application, at least a part of the linkage member 1222 may be located inside the inner tube 112. A guiding space may be formed between the side wall of the linkage member 1222 and the inner wall of the inner tube 112 for the slider 1412 to slide along the length direction of the outer tube 111.

[0318] The sliding of the slider 1412 along the length direction of the outer tube 111 may have the effect of driving the locking member 130 to switch between the fitting groove 1221a and the limit groove 140a. And it can also drive the lock pin component 142 to lock the outer tube 111 and the inner tube 112 or realize the function of the inner tube 112 sliding telescopically relative to the outer tube 111. Therefore, through the movement of the slider 1412, the lock pin component 142 and the locking member 130 can be synchronously driven, so that when the lock pin component 142 corresponds to the gear adjustment hole 111a, the locking member 130 can be located in the fitting groove 1221a corresponding to the gear adjustment hole 111a.

[0319] The embodiment of the present application also provides a cleaning device. The cleaning device may include a body and the handle assembly 100 in any of the above embodiments. The handle assembly 100 is connected to the body.

[0320] In some examples, the cleaning device may further include a clean water tank and a sewage tank. The clean water tank and the sewage tank may be provided on the floor brush assembly or on the body. Alternatively, one of the clean water tank and the sewage tank may be provided on the floor brush assembly and the other may be provided on the body. It is not limited in the embodiment of the present application.

[0321] The embodiment of the present application also provides a cleaning system. The cleaning system may include a base or a base station. The cleaning device may be placed on the base or the base station.

[0322] In some examples, the base can be used to clean the roller brush and dry the roller brush to prevent the roller brush from being in a wet state for a long time, resulting in odor or bacteria.

[0323] In some examples, the base station may have a charging function. When the cleaning device is placed on the base station, it can be charged and automatically supply and drain water. Wherein, the base and the base station may be a split structure, or the base and the base station may be an integral structure, which is not limited in the embodiment of the present application.

[0324] In some realizable ways, refer to Figures 8 to 13As shown, the handle assembly 100 of the embodiment of the present application can be applied to a cleaning device. The handle assembly 100 may include a handle body 110, a folding mechanism 120, and a telescopic mechanism 140.

[0325] 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, and the inner tube 112 is slidably connected to the outer tube 111.

[0326] The folding mechanism 120 is disposed on the handle body 110. The folding mechanism 120 may include a folding trigger 121. The folding trigger 121 is disposed on the handle body 110. The folding trigger 121 is used to control the engagement or flipping of the handle body 110 relative to the body.

[0327] The telescopic mechanism 140 is disposed on the handle body 110. The telescopic mechanism 140 includes a telescopic trigger 143. The telescopic trigger 143 is disposed on the handle body 110. The telescopic trigger 143 is used to control the sliding or locking of the inner tube 112 relative to the outer tube 111.

[0328] Wherein, there is a barrier between the operating part 1211 of the folding trigger and the operating part 1431 of the telescopic trigger.

[0329] In the embodiment of the present application, by triggering the operating part 1211 of the folding trigger, the user can make the handle body 110 engage or flip relative to the body, so that the body is in a lying flat state, and thus can be used to clean low spaces. By triggering the operating part 1431 of the telescopic trigger, the user can control the sliding or locking of the inner tube 112 relative to the outer tube 111 to adjust the length of the handle body 110, so as to be applicable to users of different heights and different application scenarios.

[0330] Since both the operating part 1211 of the folding trigger and the operating part 1431 of the telescopic trigger are disposed on the handle body 110. When the user holds the handle body 110 to clean the surface to be cleaned, when driving one of the operating part 1211 of the folding trigger and the operating part 1431 of the telescopic trigger, it is easy to accidentally touch the other, thus affecting the movement state of the handle body 110 and affecting the normal use of the user.

[0331] Therefore, a barrier can be provided between the operating part 1211 of the folding trigger and the operating part 1431 of the telescopic trigger. Wherein, the barrier may refer to a spatial barrier. There may be a large distance between the operating part 1211 of the folding trigger and the operating part 1431 of the telescopic trigger, so that when the user triggers one of them, the user's finger can hardly touch the other, thereby reducing the possibility of accidental touch.

[0332] Alternatively, the barrier can also be to block the operating portion 1211 of the folding trigger member and the operating portion 1431 of the telescopic trigger member through a physical structure. When one of them is triggered, the barrier can prevent the user from accessing the other, making it difficult for the other to be triggered.

[0333] In some implementable ways, referring to Figure 12 and Figure 13 As shown, the handle body 110 of the embodiment of the present application may further include a first gripping portion 171 and a second gripping portion 172. The first gripping portion 171 and the second gripping portion 172 can form a grip 170. At least one of the first gripping portion 171 and the second gripping portion 172 can be used to block the operating portion 1211 of the folding trigger member and the operating portion 1431 of the telescopic trigger member.

[0334] In the embodiment of the present application, when the user uses the cleaning device, the user can hold the first gripping portion 171 or the second gripping portion 172. By using at least one of the first gripping portion 171 and the second gripping portion 172 to block the operating portion 1211 of the folding trigger member and the operating portion 1431 of the telescopic trigger member, when the user holds the grip 170 and triggers one of them, at least one of the first gripping portion 171 and the second gripping portion 172 can prevent the user's fingers from touching the other.

[0335] Since when holding the first gripping portion 171 or the second gripping portion 172, the thumb and the other four fingers are respectively on both sides of the first gripping portion 171 or the second gripping portion 172, and the other four fingers except the thumb are more flexible. The other four fingers except the thumb can be used to trigger the folding trigger member 121 and the telescopic trigger member 143.

[0336] At least one of the first gripping portion 171 and the second gripping portion 172 can be used to block the operating portion 1211 of the folding trigger member and the operating portion 1431 of the telescopic trigger member. Among them, it can include: the first gripping portion 171 is used to block the operating portion 1211 of the folding trigger member and the operating portion 1431 of the telescopic trigger member; the second gripping portion 172 is used to block the operating portion 1211 of the folding trigger member and the operating portion 1431 of the telescopic trigger member; both the first gripping portion 171 and the second gripping portion 172 can be used to block the operating portion 1211 of the folding trigger member and the operating portion 1431 of the telescopic trigger member.

[0337] Taking the first holding part 171 for blocking the operating part 1211 of the folding trigger and the operating part 1431 of the telescopic trigger as an example, the operating part 1211 of the folding trigger and the operating part 1431 of the telescopic trigger can be located on both sides of the first holding part 171 respectively. When the hand holds the first holding part 171, one of the operating part 1211 of the folding trigger and the operating part 1431 of the telescopic trigger is on one side of the thumb, and the other is on the side of the four fingers. According to the conventional usage habit, the folding trigger 121 and the telescopic trigger 143 are usually triggered by the four fingers. Therefore, blocking the folding trigger 121 and the telescopic trigger 143 by the first holding part 171 can avoid the simultaneous triggering of the folding trigger 121 and the telescopic trigger 143.

[0338] The principle that the second holding part 172 can be used to block the operating part 1211 of the folding trigger and the operating part 1431 of the telescopic trigger is the same as that of the first holding part 171, and will not be elaborated here.

[0339] When both the first holding part 171 and the second holding 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, and it is not easy for the user to trigger the folding trigger 121 and the telescopic trigger 143 simultaneously.

[0340] Moreover, at least one of the first holding part 171 and the second holding part 172 can play a role in prompting the user when used as a blocker. When the user's finger touches the blocker, the blocker can prompt the user, so that the user's finger will not continue to move, thus avoiding the occurrence of accidental touch.

[0341] In some realizable ways, as shown in Figure 12 and Figure 13 , at least one of the first holding part 171 and the second holding part 172 of the embodiment of the present application forms a block for the telescopic trigger 143, so that the telescopic trigger 143 cannot be manipulated simultaneously in the state of manipulating the folding trigger 121 with one hand.

[0342] In the embodiment of the present application, the external force applied to the folding trigger 121 and the external force applied to the telescopic trigger 143 can both come from the hand holding the handle body 110. Therefore, while holding the grip 170 with one hand and applying an external force to the folding trigger 121, the user can realize the flipping of the handle body 110 relative to the fuselage with one-handed operation. Similarly, while holding the grip 170 with one hand and applying an external force to the telescopic trigger 143, the user can realize the telescoping of the handle body 110 with one-handed operation.

[0343] By setting at least one of the first holding part 171 and the second holding part 172 to form an obstruction to the telescopic trigger 143, when the folding trigger 121 is operated with one hand, the fingers of that hand will not trigger the telescopic trigger 143.

[0344] An embodiment of the present application also provides a handle assembly 100, which can be applied to a cleaning device. The handle assembly 100 may include a handle body 110, a grip 170, a folding mechanism 120, and a telescopic mechanism 140.

[0345] 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, 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 holding part 171 and a second holding part 172, and there is a holding space 170a between the first holding part 171 and the second holding part 172.

[0346] The folding mechanism 120 includes a folding trigger 121, and the folding trigger 121 is used to control the engagement or flipping of the handle body 110 relative to the body. The telescopic mechanism 140 includes a telescopic trigger 143, and the telescopic trigger 143 is used to control the sliding or locking of the inner tube 112 relative to the outer tube 111.

[0347] Among them, only one of the operating part 1211 of the folding trigger and the operating part 1431 of the telescopic trigger is located in the holding space 170a.

[0348] In the embodiment of the present 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 holding space 170a, the other one can be located outside the holding space 170a. Therefore, the first holding part 171 and / or the second holding 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 of them is triggered, it is not easy to accidentally trigger the other.

[0349] Among them, the first holding part 171 and the second holding part 172 can form a holding space 170a for accommodating fingers. When at least four fingers of the user are located in the holding space 170a, the movement direction of the cleaning device can be stably controlled.

[0350] In some implementable ways, referring to Figures 1 to 4 、 Figure 12 and Figure 13 As shown, the grip 170 of the embodiment of the present application can be located at one end of the handle body 110 away from the body. The operating part 1211 of the folding trigger and the operating part 1431 of the telescopic trigger are arranged close to the grip 170.

[0351] In the embodiments of the present application, the body can be used to connect the handle assembly 100 and the floor brush assembly. By arranging the grip 170 at one end of the handle body 110 away from the body, the grip 170 can be close to the user, facilitating the user to hold, so that the cleaning device can be controlled more comfortably for cleaning.

[0352] The folding trigger 121 and the telescopic trigger 143 can be located at one 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 arranged close to the grip 170, enabling the user to trigger one of the folding trigger 121 and the telescopic trigger 143 with one hand when holding the grip 170.

[0353] In some examples, the folding trigger 121 and the telescopic trigger 143 can be arranged on the grip 170 or on the inner tube 112, which is not limited in this embodiment.

[0354] In some examples, the first holding part 171 can be inclined relative to the inner tube 112, and the second holding part 172 can be inclined relative to the inner tube 112 to facilitate the user to hold when cleaning the surface to be cleaned, so as to slow down the bending of the wrist and relieve the fatigue at the wrist.

[0355] In some realizable ways, referring to Figures 1 to 4 As shown, relative to the surface to be cleaned, at least part of the first holding part 171 is located above the second holding part 172, and the operating part 1211 of the folding trigger is located in the holding space 170a. The operating part 1431 of the telescopic trigger can be arranged close to the second holding part 172.

[0356] Specifically, when the user holds the first holding part 171, the thumb is placed on the side of the first holding part 171 facing away from the holding space 170a, and the other four fingers are located in the holding space 170a. The four fingers with high flexibility can be used to trigger the folding trigger 121 to make the handle body 110 flip relative to the body. At this time, the second holding part 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 wrap the entire grip 170 (i.e., including the first holding part 171 and the second holding part 172) to touch the operating part 1211 of the folding trigger, which is difficult for most users of different heights, thereby reducing the possibility of triggering the folding trigger 121 and the telescopic trigger 143 simultaneously.

[0357] It should be noted that in some application scenarios, usually the same user uses the cleaning device for a long time to clean the surface to be cleaned. Therefore, after the user adjusts the length of the handle body 110 for the first time, the current length of the handle body 110 can be maintained without adjusting the length of the handle body 110 every time a cleaning operation is performed. It is easy to understand that during the process of cleaning the surface to be cleaned, the user often encounters different low spaces. Therefore, the adjustment action of the handle body 110 flipping relative to the body is more frequent than the telescopic action of the handle body 110.

[0358] Since at least part of the first holding part 171 is located above the second holding part 172, the first holding part 171 can be closer to the user. Therefore, during the cleaning process, the comfort of the user holding the first holding part 171 is higher. The frequency of the user holding the first holding part 171 is also higher. And, since the folding trigger 121 is used more frequently than the telescopic trigger 143, the folding trigger 121 can be set to be located in the holding space 170a, and the folding trigger 121 can be triggered when the first holding part 171 is held frequently.

[0359] In some implementable ways, referring to Figure 7 and Figure 13 As shown, the folding trigger 121 moves along the length direction 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.

[0360] In the embodiment of the present application, when the user holds the first holding part 171 by hand, the folding trigger 121 can be driven to move by the index finger or the middle finger. The triggering direction of the folding trigger 121 can be convenient for the user to operate, so as to have a labor-saving effect.

[0361] When the user holds the second holding part 172 by hand, the thumb can be located in the holding space 170a, and the remaining four fingers can be located on the side of the second holding part 172 facing away from the holding space 170a. The remaining four fingers can be used to drive the telescopic trigger 143 to move. The triggering direction of the telescopic trigger 143 can be convenient for the user to operate, so as to have a labor-saving effect.

[0362] In some examples, the operating part 1211 of the folding trigger can be but is not limited to a hook structure. The operating part 1431 of the telescopic trigger can be but is not limited to a plate-shaped trigger.

[0363] In some implementable ways, referring to Figure 12 and Figure 13As shown, the telescopic trigger 143 of the embodiment of the present application rotates relative to the handle body 110. The second holding part 172 is used to block the operating part 1431 of the telescopic trigger and the operating part 1211 of the folding trigger when the operating part 1431 of the telescopic trigger rotates relative to the handle body 110 to the limit position.

[0364] In some examples, when the folding trigger 121 is located in the holding space 170a, the operating part 1211 of the folding trigger and the operating part 1431 of the telescopic trigger can be respectively located on both sides of the second holding part 172. The second holding part 172 can be used to block the operating part 1431 of the telescopic trigger and the operating part 1211 of the folding trigger when the operating part 1431 of the telescopic trigger rotates relative to the handle body 110 to the limit position.

[0365] In some examples, an operation key 102 can be provided on the side of the first holding part 171 facing away from the holding space 170a. The folding trigger 121 and the operation key 102 can be respectively located on both sides of the first holding part 171. When the user holds the first holding part 171, the user can operate the operation key 102 with the thumb and can drive the operating part 1211 of the folding trigger with the other four fingers.

[0366] In some realizable ways, see Figures 8 to 11 As shown, the folding mechanism 120 can further include a traction assembly and an unlocking member 123. Along the length direction of the outer sleeve 111, the folding trigger 121 and the unlocking member 123 are respectively arranged at both ends of the traction assembly. The folding trigger 121 moves along the length direction of the outer sleeve 111 to drive the unlocking member 123 through the traction assembly to control the engagement or rotation of the handle body 110 relative to the fuselage.

[0367] In the embodiment of the present application, when the folding trigger 121 is triggered, the folding trigger 121 can transmit the acting force through the traction assembly to drive the unlocking member 123 to engage or rotate relative to the fuselage. When the unlocking member 123 engages with the fuselage, the handle body 110 and the fuselage are mutually restricted, and the handle body 110 cannot be flipped. When the unlocking member 123 can rotate relative to the fuselage, the fuselage can be in a lying state to clean low spaces.

[0368] 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 to facilitate user operation.

[0369] In some realizable ways, see 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 out of the outer tube 111.

[0370] In an embodiment of the present application, when the telescopic trigger 143 is triggered, the telescopic trigger 143 can transmit a force through the transmission assembly 141 to drive the locking pin assembly 142 to move, so as to lock or unlock the length of the inner tube 112 extending out of the outer tube 111 through the locking pin assembly 142.

[0371] An embodiment of the present application further provides a cleaning device, which may include a body and the handle assembly 100 in any of the above embodiments. The handle assembly 100 is connected to the body.

[0372] In some examples, the cleaning device may further include a clean water tank and a sewage tank. The clean water tank and the sewage tank may be provided on the floor brush assembly or on the body. Alternatively, one of the clean water tank and the sewage tank may be provided on the floor brush assembly, and the other may be provided on the body. It is not limited in the embodiments of the present application.

[0373] An embodiment of the present application further provides a cleaning system. The cleaning system may include a base or a base station. The cleaning device can be placed on the base or the base station.

[0374] In some examples, the base can be used to clean the roller brush and dry the roller brush to prevent the roller brush from being in a wet state for a long time, resulting in odor or bacteria.

[0375] In some examples, the base station may have a charging function. When the cleaning device is placed on the base station, it can be charged and automatically connected to water supply and drainage. Among them, the base and the base station may be a split structure, or the base and the base station may be an integrated structure, which is not limited in the embodiments of the present application.

[0376] See Figures 8 to 16 As shown, the handle assembly 100 of the embodiment of the present application can be applied to a cleaning device. The handle assembly 100 may include a handle body 110, a grip 170, a folding mechanism 120, and a telescopic mechanism 140.

[0377] 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, and the inner tube 112 is slidably connected to the outer tube 111. The grip 170 is provided at one end of the inner tube 112 away from the body.

[0378] 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. The folding trigger 121 is located between part of the grip 170 and the handle body 110.

[0379] The telescopic mechanism 140 and the folding mechanism 120 are arranged side by side in the inner tube 112. The telescopic mechanism 140 includes a telescopic trigger 143, which is arranged on the handle 170. The telescopic trigger 143 is used to control the inner tube 112 to slide or lock relative to the outer tube 111.

[0380] In the embodiment of the present application, it is easy to understand that the grip 170 is close to the user so that the user can hold the grip 170. By arranging the folding trigger 121 between the grip 170 and the handle body 110, the folding trigger 121 can be arranged close to the grip 170. Therefore, when the user holds the grip 170, the finger can be placed on the folding trigger 121 to facilitate triggering the folding trigger 121, thereby realizing that the handle body 110 can be flipped relative to the fuselage.

[0381] In some possible implementations, see Figures 12 to 15 As shown, the folding trigger member 121 is located at one end of the inner tube 112 away from the fuselage, and the folding trigger member 121 is located in the length direction of the outer tube 111 .

[0382] In the embodiment of the present application, by arranging the folding trigger 121 at the end of the inner tube 112 away from the fuselage, the folding trigger 121 can be closer to the user relative to the inner tube 112, so as to facilitate the user to operate the folding trigger 121. By arranging the folding trigger 121 in the length direction of the outer tube 111, the inner tube 112 can be moved along the length direction of the outer tube 111 by operating the folding trigger 121. In other words, the inner tube 112 can only have a linear motion to save the internal space of the outer tube 111, which is conducive to reducing the possibility of the inner tube 112 flipping or bending to occupy a larger internal space of the outer tube 111.

[0383] In some examples, the movement direction of the folding trigger 121 may be the same as the length direction of the outer sleeve 111. Therefore, the movement direction of the folding trigger 121 may be the same as the movement direction of the inner tube 112. The linear movement of the folding trigger 121 may cause the inner tube 112 to also move linearly to reduce the complexity of power transmission.

[0384] In some achievable ways, Figure 2 , Figure 4 and Figure 14 and Figure 15As shown, the grip 170 includes a first gripping portion 171. The telescopic trigger 143 is located between the first gripping portion 171 and the inner tube 112.

[0385] In the embodiment of the present application, when the user holds the first gripping portion 171 with the hand, at least part of the fingers can be placed in the space between the first gripping portion 171 and the inner tube 112. Therefore, at least part of the user's fingers can easily touch the telescopic trigger 143 between the first gripping portion 171 and the inner tube 112. When the user holds the first gripping portion 171, the operation of the telescopic trigger 143 can be realized without visual participation.

[0386] In some implementable ways, referring to Figure 12 , Figure 13 and Figure 15 As shown, there is a barrier between the folding trigger 121 and the display screen 101 on the grip 170.

[0387] In the embodiment of the present application, a display screen 101 is provided on the grip 170. Among them, the display screen 101 may refer to the display screen 101 existing on the grip 170 in the related art. The display screen 101 may have a display function. Or, the display screen 101 may also have display and touch functions. By having a barrier between the folding trigger 121 and the display screen 101, on the one hand, the barrier can be used to provide support for the display screen 101. On the other hand, according to ergonomics, by having a barrier between the folding trigger 121 and the display screen 101, a distance can be formed between the folding trigger 121 and the display screen 101. When the user holds the grip 170 with the palm of the hand, the thumb can directly operate the display screen 101 or the operation keys 102 near the display screen 101. When the remaining four fingers are placed downwards accordingly, one of the fingers (such as the index finger) can easily touch the folding trigger 121.

[0388] In some examples, the barrier between the folding trigger 121 and the display screen 101 and the first gripping portion 171 may be an integral structure.

[0389] In some implementable ways, referring to Figure 12 , Figure 13 and Figure 15 As shown, there is a barrier between the folding trigger 121 and the operation keys 102 on the grip 170.

[0390] In the embodiment of the present application, the barrier between the folding trigger 121 and the operation key 102 can separate the folding trigger 121 and the operation key 102. There is a distance between the folding trigger 121 and the operation key 102, so that when the user holds the grip 170, it can conform to ergonomics, thereby improving the comfort of the user's operation of the folding trigger 121 and the operation key 102. Specifically, when the user's palm holds the first holding part 171, the thumb can easily operate the operation key 102, and the other four fingers can be placed down accordingly, so that one of the other four fingers (such as the index finger) can touch the folding trigger 121 accordingly. Thus, the user can operate the folding trigger and the operation key 102 without switching fingers or excessive visual participation.

[0391] In some implementable ways, referring to Figure 12 , Figure 13 and Figure 15 As shown, along the thickness direction of the display screen 101, at least part of the orthographic projection of the folding trigger 121 is located inside the orthographic projection of the display screen 101.

[0392] In the embodiment of the present application, through the above settings, the display screen 101 is not easily blocked by the palm or fingers. Moreover, when the user needs to operate the folding trigger 121 when viewing the display screen 101, the user does not need to shift the line of sight anymore and can easily trigger the folding trigger 121. Specifically, when the user holds the grip 170, according to the user's holding habit, the position of the thumb and the palm is not likely to block the display screen 101, so as to facilitate the user to view the display screen 101. At this time, during the process of the other four fingers being placed down accordingly, one of the fingers can be easily placed on the folding trigger 121.

[0393] In some implementable ways, referring to Figure 12 , Figure 13 and Figure 15 As shown, along the pressing direction of the operation key 102, at least part of the orthographic projection of the folding trigger 121 overlaps with the orthographic projection of the operation key 102.

[0394] In the embodiment of the present application, through the above settings, when the operation key 102 is not easily blocked by the palm or fingers, the user can easily trigger the folding trigger 121. Moreover, when the user can easily trigger the folding trigger 121, the operation key 102 is not easily blocked by the palm or fingers and misoperation occurs.

[0395] Specifically, the grip 170 faces the user so that the operation key 102 faces the user. When the user holds the grip 170, the thumb and the palm of the hand will consciously not block the operation key 102 to facilitate the operation of the operation key 102. At this time, according to ergonomics, when the other four fingers are placed down, one of the fingers can be easily placed on the folding trigger 121. Therefore, when the user triggers the folding trigger 121, there is no need to switch the line of sight.

[0396] In some examples, the pressing direction of the operation key 102 may be perpendicular to the upper surface of the first grip portion 171. When the operation key 102 is a physical key, the pressing direction of the operation key 102 may refer to the movement direction of the operation key 102. When the operation key 102 is a touch key, the pressing direction of the operation key 102 may refer to the direction in which the user applies a trigger force to the first grip portion 171.

[0397] In some possible implementations, see Figure 2 , Figure 4 and Figure 14 As shown, the handle body 110 is rotatably connected to the body via a rotation axis 180. The inner tube 112 and the outer tube 111 are located between the rotation axis 180 and the grip 170.

[0398] In the embodiment of the present application, the fuselage is used to connect the handle assembly 100 and the floor brush assembly. The fuselage is rotatably connected to the handle body 110 of the handle assembly 100 via a rotating shaft 180. Therefore, it is easy to understand that the rotating shaft 180 is closer to the surface to be cleaned relative to the handle body 110. The user can operate the end of the handle body 110 away from the rotating shaft 180. When cleaning a low space, the user can operate the trigger folding trigger 121 so that the handle body 110 can rotate through the rotating shaft 180. The fuselage and the surface to be cleaned can be horizontal, and the fuselage is in a lying state. At this time, there is an inclination angle between the handle body 110 and the fuselage. The user can extend at least part of the fuselage into the low space without bending over to clean the surface to be cleaned in the low space.

[0399] Furthermore, since the inner tube 112 of the embodiment of the present application can slide along the length direction of the outer tube 111, when the body is in a flat state, the user can adjust the length of the inner tube 112 extending from the outer tube 111 to meet the use needs of users of different heights.

[0400] In some possible implementations, the handle body 110 is rotatably connected to the body via a rotation axis 180 . The telescopic mechanism 140 is located between the rotation axis 180 and the grip 170 .

[0401] In the embodiments of the present application, at least a part of the telescopic mechanism 140 moves within the inner tube 112. The telescopic mechanism 140 can be used to implement the telescoping of the handle body 110. Since the inner tube 112 can slide along the length direction of the outer tube 111, by arranging the telescopic mechanism 140 between the rotating shaft 180 and the grip 170, the space between the rotating shaft 180 and the grip 170 can be reasonably utilized, which is beneficial to reducing the possibility that the telescopic mechanism 140 occupies extra space, resulting in an overly large length dimension of the handle body 110 and thus making it difficult to meet the usage requirements of users of different heights.

[0402] In some implementable ways, referring to Figure 8 and Figure 11 as shown, the telescopic mechanism 140 includes a telescopic reset member 1424. The telescopic reset member 1424 is arranged on the handle body 110. The telescopic reset member 1424 is used to drive the telescopic trigger member 143 to reset. Along the length direction of the outer tube 111, the telescopic trigger member 143 and the telescopic reset member 1424 are respectively located at both ends of the inner tube 112.

[0403] In the embodiments of the present application, when the telescopic trigger member 143 is triggered, the handle body 110 can be telescoped to adjust the length of the handle body 110. When the user releases the triggering driving force on the telescopic reset member 1424, by arranging the telescopic reset member 1424, it can be used to drive the telescopic trigger member 143 to reset to the untriggered state. At this time, the length of the handle body 110 can be locked.

[0404] In some implementable ways, referring to Figure 8 and Figure 11 as shown, the telescopic mechanism 140 may further include a transmission assembly 141 and a locking pin assembly 142. The transmission assembly 141 can connect the telescopic trigger member 143 and the locking pin assembly 142. The telescopic trigger member 143 can drive the locking pin assembly 142 to move. 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. The telescopic reset member 1424 can be used to drive the locking pin assembly 142 to reset.

[0405] In the embodiments of the present application, the telescopic reset member 1424 can, while having the function of driving the telescopic trigger member 143 to reset, also have the function of driving the locking pin assembly 142 to lock or unlock the inner tube 112 and the outer tube 111.

[0406] Specifically, when the telescopic trigger 143 is triggered, the transmission assembly 141 can transmit a 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 sleeve 111 to adjust the length of the handle body 110. Moreover, the movement of the locking pin assembly 142 can also make the telescopic reset member 1424 in a compressed state, and the telescopic reset member 1424 can accumulate the force of deformation.

[0407] When the triggering driving force of the telescopic trigger 143 is released, on the one hand, the telescopic reset member 1424 can drive the telescopic trigger 143 to reset, and on the other hand, the telescopic reset member 1424 can release the 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.

[0408] In some implementable ways, see Figure 16 As shown, the telescopic trigger 143 is connected to the transmission assembly 141. The transmission assembly 141 moves forward or backward in the inner tube 112.

[0409] In the embodiment of the present application, by setting the transmission assembly 141 to move forward or backward in the inner tube 112, the locking pin assembly 142 can be in a locked state or an unlocked state. When the locking pin assembly 142 is in the locked state, the inner tube 112 and the outer sleeve 111 are relatively fixed. When the locking pin assembly 142 is in the unlocked state, the inner tube 112 and the outer sleeve 111 can slide relative to each other.

[0410] Since the telescopic trigger 143 is connected to the transmission assembly 141, the telescopic trigger 143 can make the transmission assembly 141 move forward or backward in the inner tube 112. The telescopic trigger 143 is movably connected to the handle body 110 to drive the transmission assembly 141 to move forward or backward. Among them, the telescopic trigger 143 can be, but is not limited to, slidably connected to the handle body 110, or the telescopic trigger 143 can be flipped relative to the handle body 110, which is not specifically limited in this application.

[0411] In some examples, the telescopic trigger 143 can be, but is not limited to, a push button structure, a push rod structure, etc.

[0412] In some implementable ways, see Figure 15 and Figure 16 As shown, the telescopic trigger 143 has a triggering movement and a reset movement. When the telescopic trigger 143 is triggered, the transmission assembly 141 moves leftward along the length direction of the outer sleeve 111. The inner tube 112 and the outer sleeve 111 can slide relative to each other. When the telescopic trigger 143 is reset, the transmission assembly 141 moves rightward along the length direction of the outer sleeve 111, and the inner tube 112 and the outer sleeve 111 are relatively fixed.

[0413] In the embodiments of the present application, the telescopic trigger member 143 is slidably connected to the handle body 110. Refer to Figure 15 and Figure 16 In the direction of, when the telescopic trigger member 143 triggers a movement, the telescopic trigger member 143 can slide to the left to drive the transmission assembly 141 to move synchronously to the left along the length direction of the outer sleeve 111. Since the transmission assembly 141 is connected to the locking pin assembly 142. When the transmission assembly 141 moves to the left, the adapter 1422 of the locking pin assembly 142 can be slid to the left. At this time, the locking pin body 1421 can be disengaged from the gear adjustment hole 111a of the outer sleeve 111, so that the locking pin assembly 142 is unlocked from the handle body 110, and the inner tube 112 of the handle body 110 can slide relative to the outer sleeve 111.

[0414] When the telescopic trigger member 143 returns to its original position, the telescopic trigger member 143 can slide to the right to drive the transmission assembly 141 to move to the right along the length direction of the outer sleeve 111. Since the transmission assembly 141 is connected to the locking pin assembly 142. When the transmission assembly 141 moves to the right, the adapter 1422 of the locking pin assembly 142 can be slid to the right. At this time, the locking pin body 1421 can be inserted into the gear adjustment hole 111a of the outer sleeve 111 under the action of the adapter 1422. The locking pin body 1421 can lock the handle body 110. The inner tube 112 of the handle body 110 is fixed relative to the outer sleeve 111.

[0415] In some examples, when the telescopic trigger member 143 is slidably connected to the handle body 110, refer to Figure 1 In the direction shown, the direction of the triggering movement of the telescopic trigger member 143 can be downward, so as to facilitate the user to apply a force to the telescopic trigger member 143. Specifically, the user can hold the grip 170 with one hand and make the telescopic trigger member 143 have a triggering movement downward with the other hand.

[0416] In some examples, the locking pin assembly 142 may further include a telescopic reset member 1424. When the triggering movement applied by the user to the telescopic trigger member 143 is cancelled, the telescopic reset member 1424 can drive the adapter 1422 to move to the right to drive the locking pin column of the locking pin body 1421 to be inserted into the gear adjustment hole 111a through the adapter 1422.

[0417] In some examples, an outer protective tube may also be sleeved outside the outer sleeve 111. The protective tube can prevent the gear adjustment hole 111a from being exposed, so as to reduce the possibility that dust, debris, liquid, etc. enter the inside of the handle body 110 through the gear adjustment hole 111a, resulting in jamming of the movement of internal structures such as the telescopic mechanism 140. And it can also improve the aesthetics of the handle assembly 100.

[0418] In some realizable ways, refer to Figure 15As shown, the grip 170 further includes a second gripping portion 172. There is a gripping space 170a between the first gripping portion 171 and the second gripping portion 172. Only one of the operating portion 1211 of the folding trigger member and the operating portion 1431 of the telescopic trigger member is located within the gripping space 170a.

[0419] In the embodiment of the present application, when only one of the operating portion 1211 of the folding trigger member and the operating portion 1431 of the telescopic trigger member is located within the gripping space 170a, the other one can be located outside the gripping space 170a. Therefore, the first gripping portion 171 and / or the second gripping portion 172 can be used to block the operating portion 1211 of the folding trigger member and the operating portion 1431 of the telescopic trigger member, so that when one of them is triggered, it is not easy to accidentally trigger the other one.

[0420] See Figures 8 to 13 As shown, the handle assembly 100 of the embodiment of the present application can be applied to a cleaning device. The handle assembly 100 may include a handle body 110, a grip 170, a folding mechanism 120, and a telescopic mechanism 140.

[0421] 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, and the inner tube 112 is slidably connected to the outer tube 111. The grip 170 is provided at one end of the inner tube 112 away from the body.

[0422] At least a part of the folding mechanism 120 is located within the inner tube 112. The folding mechanism 120 includes a folding trigger member 121. The folding trigger member 121 is provided on the grip 170, and the folding trigger member 121 is used to control the engagement or flipping of the handle body 110 relative to the body.

[0423] The telescopic mechanism 140 and the folding mechanism 120 are arranged side by side within the inner tube 112. The telescopic mechanism 140 includes a telescopic trigger member 143. The telescopic trigger member 143 is provided on the grip 170. The telescopic trigger member 143 is used to control the sliding or locking of the inner tube 112 relative to the outer tube 111.

[0424] Wherein, the non-operating end of the folding trigger member 121 is close to the non-operating end of the telescopic trigger member 143. The non-operating end of the telescopic trigger member 143 and the non-operating end of the folding trigger member 121 have a mutually locking state, so that when the telescopic trigger member 143 is triggered, the folding trigger member 121 is locked.

[0425] In the embodiment of the present application, when the telescopic trigger 143 is triggered, the handle body 110 can be telescoped, and the length of the handle body 110 can be adjusted. By setting the non-operating end of the telescopic trigger 143 and the non-operating end of the folding trigger 121 to have a mutually locked state, the folding trigger 121 can be prevented from being triggered when the handle body 110 is in a telescopic state. In other words, when the handle body 110 is telescoped, the flipping movement of the handle body 110 relative to the body can be locked. The telescoping and flipping of the handle body 110 do not occur simultaneously.

[0426] Therefore, it is possible to reduce the possibility that the telescoping movement and the flipping movement of the handle body 110 occur simultaneously, which makes it difficult to control the handle body 110, thereby affecting the cleaning efficiency and the user experience. The telescoping movement and the flipping movement of the handle body 110 can be performed separately to improve the reliability of the telescoping movement and the flipping movement.

[0427] The embodiment of the present application further provides a handle assembly 100, which can be used for a cleaning device. The handle assembly 100 may include a handle body 110, a grip 170, a folding mechanism 120, and a telescoping mechanism 140.

[0428] 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, and the inner tube 112 is slidably connected to the outer tube 111.

[0429] At least a part of the folding mechanism 120 is located in the inner tube 112. The folding mechanism 120 includes a folding trigger 121. The folding trigger 121 is used to control the engagement or flipping of the handle body 110 relative to the body. The folding trigger 121 is provided with a first engaging portion 1432.

[0430] The telescoping mechanism 140 and the folding mechanism 120 are arranged side by side in the inner tube 112. The telescoping mechanism 140 includes a telescoping trigger 143. The telescoping trigger 143 is used to control the sliding or locking of the inner tube 112 relative to the outer tube 111. The telescoping trigger 143 is provided with a second engaging portion 1212 that cooperates with the first engaging portion 1432.

[0431] When the telescoping trigger 143 is triggered, the first engaging portion 1432 and the second engaging portion 1212 can engage with each other, and the folding trigger 121 is locked.

[0432] In the embodiments of the present application, the folding trigger 121 can be used to achieve the flipping movement of the handle body 110 relative to the fuselage. The telescopic trigger 143 can be used to achieve the telescopic movement of the handle body 110. By setting the first engaging portion 1432 and the second engaging portion 1212 to engage with each other, when the telescopic trigger 143 is triggered, the folding trigger 121 can be locked, so that the flipping movement and the telescopic movement of the handle body 110 can be carried out separately, which is beneficial to improving the reliability of the telescopic movement and the flipping movement of the handle body 110.

[0433] Specifically, when the telescopic trigger 143 is triggered, the telescopic trigger 143 can cause the handle body 110 to telescope, and relative sliding can occur 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 cooperate with each other through the first engaging portion 1432 and the second engaging portion 1212, so that the folding trigger 121 can be in a locked state, and thus the folding trigger 121 will not cause the handle body 110 to flip relative to the fuselage.

[0434] The non-operating end of the telescopic trigger 143 and the non-operating end of the folding trigger 121 can be close to each other to facilitate locking the folding trigger 121 through the action of the telescopic trigger 143 when the telescopic trigger 143 is triggered. It should be noted that when holding the grip 170 with one hand and both the telescopic trigger 143 and the folding trigger 121 can be operated with one hand, the operating portion 1431 of the telescopic trigger and the operating portion 1211 of the folding trigger need to meet the condition that they cannot be triggered simultaneously with one hand.

[0435] In some realizable ways, referring to Figure 12 and Figure 13 As shown, when the telescopic trigger 143 of the embodiments of the present application 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.

[0436] In the embodiment of the present application, when the telescopic trigger 143 is triggered, the movement of the telescopic trigger 143 can cause 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 and the non-operating end of the folding trigger 121. When the telescopic trigger 143 is reset, through the reset movement of the telescopic trigger 143, the first engaging portion 1432 and the second engaging portion 1212 can be separated from each other, thereby releasing the binding force between the first engaging portion 1432 and the second engaging portion 1212, and unlocking the non-operating end of the telescopic trigger 143 and the non-operating end of the folding trigger 121.

[0437] After the telescopic state of the handle body 110 is adjusted, the telescopic trigger 143 can be reset. At this time, the user can trigger the folding trigger 121 so that the handle body 110 can be flipped relative to the fuselage.

[0438] In some implementable ways, refer to Figures 8 to 13 As shown, the folding trigger 121 of the embodiment of the present application moves along the length direction of the outer sleeve 111 to control the engagement or rotation of the handle body 110 relative to the fuselage. 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 direction of the outer sleeve 111.

[0439] In the example of the present application, 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 in the length direction of the outer sleeve 111.

[0440] Specifically, referring to Figure 12 and Figure 13 As shown in the direction, when the telescopic trigger 143 is triggered to rotate the operating portion counterclockwise, the non-operating end of the telescopic trigger 143 can be close to the non-operating end of the folding trigger 121. When the telescopic trigger 143 moves to the limit position, the non-operating end of the telescopic trigger 143 and the non-operating end of the folding trigger 121 can be connected, and the non-operating end of the telescopic trigger 143 can prevent the folding trigger 121 from moving in the triggered direction to lock the folding trigger 121.

[0441] In some implementable ways, refer to Figures 8 to 11 As shown, the telescopic mechanism 140 of the embodiment of the present application can include a telescopic reset member 1424. The telescopic reset member 1424 can be disposed on the handle body 110. The telescopic reset member 1424 is used to drive the telescopic trigger 143 to reset, so that the non-operating end of the telescopic trigger 143 and the non-operating end of the folding trigger 121 are unlocked.

[0442] In the embodiments of the present application, when the user releases the triggering driving force on the telescopic reset member 1424, by setting the telescopic reset member 1424, it can be used to prompt the telescopic reset member 1424 to return 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, realizing the unlocking of the non-operating end of the telescopic trigger member 143 and the non-operating end of the folding trigger member 121.

[0443] In some examples, the handle assembly 100 may further include an elastic reset member. When the triggering driving force of the telescopic reset member 1424 is released, the elastic reset member can be used to drive the telescopic trigger member 143 to reset.

[0444] Exemplarily, one end of the elastic reset member may be fixed to the inner wall of the grip 170, and the other end of the elastic reset member may 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.

[0445] In some implementable ways, along the length direction of the outer sleeve 111, the telescopic trigger member 143 and the telescopic reset member 1424 may be respectively located at both ends of the inner tube 112.

[0446] In the embodiments of the present application, since the non-operating end of the telescopic trigger member 143 and the non-operating end of the folding trigger member 121 are close to each other, and the space around the telescopic trigger member 143 is limited. Therefore, by setting the telescopic reset member 1424 at the end of the inner tube 112 far from the telescopic trigger member 143, the structure at the non-operating end of the telescopic trigger member 143 and the non-operating end of the folding trigger member 121 can be simplified while realizing the reset movement of the telescopic trigger member 143.

[0447] In some implementable ways, as shown in Figures 8 to 13 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 member 143 and the locking pin assembly 142. The telescopic trigger member 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 sleeve 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.

[0448] In the embodiments of the present application, the telescopic reset member 1424 can, on the basis of having the function of driving the telescopic trigger member 143 to reset, also have the function of driving the locking pin assembly 142 to lock or unlock the inner tube 112 and the outer sleeve 111.

[0449] Specifically, when the telescopic trigger member 143 is triggered, the transmission assembly 141 can transmit a 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 sleeve 111 to adjust the length of the handle body 110. Moreover, the movement of the locking pin assembly 142 can also cause the telescopic reset member 1424 to be in a compressed state, and the telescopic reset member 1424 can accumulate the force of deformation.

[0450] When the triggering driving force of the telescopic trigger member 143 is released, on the one hand, the telescopic reset member 1424 can drive the telescopic trigger member 143 to reset. On the other hand, the telescopic reset member 1424 can release the elastic potential energy and transmit it to the telescopic trigger member 143 through the transmission assembly 141, so that the telescopic trigger member 143 can be reset.

[0451] In some implementable ways, referring to Figures 1 to 4 as shown, the folding trigger member 121 and the telescopic trigger member 143 of the embodiment of the present application can be located at the end of the handle body 110 away from the fuselage. There is a barrier between the operation part 1211 of the folding trigger member and the operation part 1431 of the telescopic trigger member.

[0452] By arranging the folding trigger member 121 and the telescopic trigger member 143 at one end of the handle body 110 away from the fuselage, the folding trigger member 121 and the telescopic trigger member 143 can be close to the user, which is convenient for the user to operate the folding trigger member 121 and the telescopic trigger member 143.

[0453] Since the folding trigger member 121 and the telescopic trigger member 143 are located at the same end of the handle body 110, by arranging a barrier between the operation part 1211 of the folding trigger member and the operation part 1431 of the telescopic trigger member, when one of the folding trigger member 121 and the telescopic trigger member 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.

[0454] In some examples, the folding trigger member 121 and the telescopic trigger member 143 are located at the end of the inner tube 112 away from the fuselage, and the operation part 1211 of the folding trigger member and the operation part 1431 of the telescopic trigger member can be arranged close to the grip 170, so that when the user holds the grip 170, one of the folding trigger member 121 and the telescopic trigger member 143 can be triggered with one hand.

[0455] In some implementable ways, referring to Figure 12 and Figure 13 as shown, one of the first engaging part 1432 and the second engaging part 1212 can be a locking groove structure, and the other of the first engaging part 1432 and the second engaging part 1212 can be a convex structure.

[0456] When the telescopic trigger 143 is triggered, the convex structure and the locking groove structure cooperate with each other to restrict the folding trigger 121 from being triggered. When the telescopic trigger 143 resets, the convex structure disengages from the locking groove structure, and the folding trigger 121 is in a state where it can be triggered.

[0457] In the embodiment of the present application, through the mutual cooperation of the convex structure and the locking groove structure, the structure is simple, convenient for processing and production, and has high movement reliability.

[0458] Reference Figure 12 and Figure 13 Taking the first engaging portion 1432 as the locking groove structure and the second engaging portion 1212 as the convex structure in the shown direction 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 restrictive surfaces, and the second engaging portion 1212 can restrict the first engaging portion 1432 from moving to the right to the position where the folding trigger 121 is triggered, so as to realize the locking of 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 restraining force of the second engaging portion 1212 on the first engaging portion 1432 is released, and at this time the folding trigger 121 can be triggered.

[0459] It should be noted that when the telescopic trigger 143 resets, the reset movement of the telescopic reset member 1424 can cause the second engaging portion 1212 and the first engaging portion 1432 to automatically disengage without applying other forces or through other structures.

[0460] In some examples, when the first engaging portion 1432 is the locking groove structure, referring to Figure 12 and Figure 13 the shown direction, the opening direction of the first engaging portion 1432 can face downward to facilitate the second engaging portion 1212 of the telescopic trigger 143 to enter or exit.

[0461] In some realizable ways, the grip 170 is arranged at the end of the inner tube 112 away from the fuselage, and the folding trigger 121 and the telescopic trigger 143 are arranged on the grip 170. Among them, the non-operating ends of the folding trigger 121 and the telescopic trigger 143 are located inside the grip 170.

[0462] The embodiment of the present application further provides a cleaning device, and the cleaning device may include a fuselage and the handle assembly 100 in any of the above embodiments. The handle assembly 100 is connected to the fuselage.
