Description

Technical Field

[0001] This application relates to the technical field of household appliances, and particularly to a handle assembly and a cleaning device having the same. Background Art

[0002] Existing cleaning devices generally include a cleaning component and a handle assembly for pushing and pulling the cleaning component. The cleaning component closely adheres to the ground for cleaning work, and the handle assembly reaches the user's hand for the user to operate. However, there are many low spaces in the household cleaning scenario, such as under the sofa, under the bed, etc. Traditional cleaning devices cannot lie flat during the cleaning process. Taking a floor washer as an example, since the main body of the floor washer is installed on the handle assembly, it cannot lie flat close to the ground during the use of the cleaning device, resulting in the cleaning device being unable to effectively clean low positions.

[0003] Although there are floor washers on the market that can lie flat for cleaning, the main body of the floor washer can lie flat at 180°, enabling the cleaning of low positions. However, when cleaning low positions, the user needs to squat down or bend down significantly to flatten the main body of the cleaning device, such cleaning actions are very laborious, and the actions of squatting and bending are also prone to accidents, resulting in a poor user experience. Summary of the Utility Model

[0004] In view of this, this application provides a handle assembly and a cleaning device having the same, so as to solve the technical problem that the user needs to squat down or bend down significantly when using a floor washer that can lie flat for cleaning low positions in the prior art.

[0005] In a first aspect, this application provides a handle assembly. The handle assembly is connected to the cleaning component of the cleaning device and is used for pushing and pulling the cleaning component to move. The handle assembly includes: a joint assembly, including a first joint and a second joint. One end of the first joint is connected to the cleaning component, and the other end of the first joint is connected to the second joint through a rotating shaft; a telescopic component, the telescopic component is arranged on the second joint and has a contracted state and an extended state; a locking mechanism, the locking mechanism is arranged on the telescopic component and is used for locking the telescopic component in the contracted state or the extended state.

[0006] Beneficial effects: The handle assembly proposed in this application, through the cooperation of the joint assembly and the telescopic component, the user can control the pitching, turning, pushing and pulling of the cleaning component through the handle assembly, thereby improving the spatial adaptability of the cleaning component and the cleaning device. At the same time, by using a telescopic and bendable handle assembly, the technical problem that the user needs to squat down or bend down significantly when using a floor washer that can lie flat for cleaning low positions is solved.

[0007] In an alternative embodiment, the telescopic component includes a sleeve and a sliding tube. The sleeve is sleeved on the second joint, and the sliding tube is slidably sleeved on the sleeve. The sliding tube has a contracted state where it slides to sleeve the rotating shaft, and an extended state where it disengages from the rotating shaft.

[0008] Advantageous effects: Considering that the relative rotation between the second joint and the first joint may affect the requirement that the handle assembly needs to be parallel to the cleaning component during normal cleaning of the cleaning device, the embodiment of the present application proposes that when the telescopic component is in the contracted state, the sliding tube will sleeve the rotating shaft between the second joint and the first joint, so that the second joint and the first joint cannot rotate relative to each other.

[0009] Furthermore, when the cleaning device is in the normal use state and the telescopic component is in the contracted state, a part of the sliding tube is inserted into the interior of the cleaning component and is limited, so as to achieve the purpose that the handle assembly and the cleaning component of the cleaning device do not generate a rotation angle.

[0010] In an alternative embodiment, the locking mechanism includes a hook and a clamping structure. One of the hook and the clamping structure is arranged on the sleeve, and the other of the hook and the clamping structure is arranged on the sliding tube. When the telescopic component is in the contracted state, the hook is clamped to the clamping structure.

[0011] Advantageous effects: Whether the hook is arranged on the sleeve and the clamping structure is arranged on the sliding tube, or the clamping structure is arranged on the sleeve and the hook is arranged on the sliding tube, both can achieve the purpose of locking the sliding tube and the sleeve, so that the handle assembly is in a relatively stable working state.

[0012] In an alternative embodiment, the clamping structure includes a clamping plate arranged inside the sliding tube. The sleeve is provided with a cantilever extending into the sleeve. The hook is arranged at the free end of the cantilever, and the hook is provided with an inclined guiding portion facing the clamping plate.

[0013] Advantageous effects: When the telescopic component is in the contracted state, the hook on the sleeve is buckled on the clamping structure of the sliding tube, so that the sliding tube cannot slide relative to the sleeve; when it is necessary to unlock the telescopic component, the hook on the sleeve is separated from the clamping structure of the sliding tube, realizing the unlocking of the telescopic component, so that the telescopic component can extend.

[0014] In an alternative embodiment, the locking mechanism further includes a button assembly. The button assembly includes a button and an elastic element. The button is installed at a position corresponding to the hook on the sliding tube through the elastic element, and the button is arranged to be able to press the hook to disengage from the clamping plate.

[0015] Beneficial effects: When the telescopic component is in the retracted state, the hook on the sleeve is buckled on the clamping structure of the sliding tube, preventing the sliding tube from sliding relative to the sleeve; when it is necessary to unlock the telescopic component, press the button component, and the button of the button component presses on the hook of the sleeve, causing the hook to deform downward and separate from the clamping structure of the sliding tube, realizing the unlocking of the telescopic component and enabling the telescopic component to extend.

[0016] In an alternative embodiment, the locking mechanism further includes an elastic buckle, the elastic buckle is installed on the sleeve, and the sliding tube is provided with a positioning hole that can be clamped to the elastic buckle. When the telescopic component is in the extended state, the sliding tube is clamped to the elastic buckle.

[0017] Beneficial effects: When the telescopic component is in the extended state, the positioning hole of the sliding tube is clamped to the elastic buckle of the sleeve, preventing the sliding tube and the sleeve from moving relative to each other. Then rotate the second joint to change the angle α between it and the first joint to 50° - 60°. In this way, the cleaning component of the cleaning device can be in a lying flat and low position, while the handle component is in a high position for convenient user grip. The user controls the forward and backward movement and the twisting and turning of the cleaning component of the cleaning device through the handle component.

[0018] In an alternative embodiment, both the sleeve and the sliding tube are provided as flat tubes, the sleeve is circumferentially fixedly slidable relative to the sliding tube, the clamping plate is arranged at the long axis end of the sliding tube, and the inclined guiding part of the hook faces the long axis end of the sliding tube.

[0019] Beneficial effects: By setting both the sleeve and the sliding tube as flat tubes, sufficient installation space and moving space can be provided for the hook and the clamping plate, thereby reducing the phenomenon that the hook cannot disengage from the clamping plate due to limited moving space.

[0020] In an alternative embodiment, the telescopic component includes a connecting rod and a folding rod, the connecting rod is connected to the second joint, the folding rod is rotatably connected to the connecting rod, and the folding rod has a retracted state of folding onto the connecting rod and an extended state of unfolding relative to the connecting rod.

[0021] Beneficial effects: The handle component proposed in this application solves the technical problem that the user needs to squat or bend down significantly when cleaning low positions with a flat - lying floor - washing machine by using a telescopic and bendable handle component.

[0022] In a second aspect, the present application provides a cleaning device, the cleaning device includes a cleaning component and a handle component according to the second aspect of the present application, and the handle component is connected to the cleaning component through a joint component.

[0023] Beneficial effects: The cleaning device proposed in this application has all the technical effects of the handle component, and will not be elaborated in detail here.

[0024] In an alternative embodiment, the cleaning assembly includes a floor brush and a main body. The main body is rotatably connected to the floor brush. The first joint of the joint assembly is connected to the main body, and the main body can be in a lying state or an upright state under the drive of the joint assembly.

[0025] Advantageous effects: During the normal use of the cleaning device, the handle assembly is in a retracted state. At this time, the main body is in an upright state; during the process of using the cleaning device to clean low positions, the handle assembly is in an extended and bent state. At this time, the main body is in a lying state. This improves the applicable range of the handle assembly for different cleaning positions and the user experience when cleaning different positions.

Apparently, the described embodiments are some, but not all, of the embodiments of the present application.

[0045] In the description of the present application, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "communication" should be understood in a broad sense. For example, it can be fixedly connected, detachably connected, or integrally connected; it can be mechanically connected or electrically connected; it can be directly connected or indirectly connected through an intermediate medium, and it can also be the connection inside two components.

[0046] The main components of cleaning equipment such as a floor washer include a floor brush, a sewage tank, a clean water tank, a main body, and a handle assembly. Its working principle is as follows: The water pump pumps the water in the clean water tank and sprays it onto the roller brush of the floor brush to wet the roller brush. Through the rotation of the roller brush, the cleaning purpose is achieved. The vacuum motor in the main body generates suction, sucks the sewage through the suction port on the floor brush into the pipeline and sends it to the sewage tank. The handle assembly plays the role of pushing and pulling the floor brush and installing human-computer interaction devices.

[0047] Through a user experience survey of a floor washer that can lie flat for cleaning, it is found that there is a problem that when cleaning low positions, it is necessary to squat or bend down significantly. The reason for this problem is that the handle assembly of the floor washer is rigidly connected to the body, and the length of the handle assembly is designed for normal standing use. When the main body lies flat to clean low positions, it is necessary to lower the handle assembly close to the ground. At this time, the user needs to squat or bend down significantly to hold the handle assembly and control the floor washer.

[0048] In order to solve the technical problem in the prior art that when a floor washer that can lie flat for cleaning cleans low positions, it is necessary to squat or bend down significantly, the embodiment of the present application adopts a retractable and bendable handle assembly, achieving the technical effect that the user can operate the cleaning equipment upright to clean low positions.

[0049] The following will be combined with Figures 1 to 9 , to describe the embodiments of the present application.

[0050] As Figures 1 to 9 shown, according to the embodiment of the present application, on the one hand, the present application provides a handle assembly 100. The handle assembly 100 is connected to the cleaning assembly 200 of the cleaning equipment 1000 and is used to push and pull the cleaning assembly 200 to move. The handle assembly 100 includes a joint assembly 10, a telescopic assembly 20, and a locking mechanism 30. The joint assembly 10 includes a first joint 11 and a second joint 12. One end of the first joint 11 is connected to the cleaning assembly 200, and the other end of the first joint 11 is connected to the second joint 12 through a rotating shaft 13. The telescopic assembly 20 is arranged on the second joint 12 and has a contracted state and an extended state. The locking mechanism 30 is arranged on the telescopic assembly 20 and is used to lock the telescopic assembly 20 in the contracted state or the extended state.

[0051] In this embodiment, the handle assembly 100 proposed in the embodiments of the present application is matched with the joint assembly 10 and the telescopic assembly 20. The user can control the pitching, steering, and forward and backward pulling of the cleaning assembly 200 through the handle assembly 100, thereby improving the spatial adaptability of the cleaning assembly 200 and the cleaning device 1000. At the same time, by using the telescopic and bendable handle assembly 100, the technical problem that the user needs to squat or bend down significantly when cleaning low positions with a flat-lying floor washer is solved.

[0052] Specifically, taking a floor washer as an example, the function of the joint assembly 10 provided in the embodiments of the present application is to dock the handle assembly 100 with the cleaning assembly 200 of the cleaning device 1000. For example, it is docked and fixed with the main body 220 of the floor washer. At the same time, the joint assembly 10 can change the included angle between the handle assembly 100 and the main body 220 of the floor washer. The joint assembly 10 is arranged at the top of the main body 220 of the floor washer and is composed of a first joint 11 and a second joint 12, which are rotatably connected through a rotating shaft 13, so that the first joint 11 and the second joint 12 can rotate relative to each other through the rotating shaft 13. By the relative rotation of the two, the technical problem that the user needs to squat and bend down when using the floor washer for flat-lying cleaning is solved. The reason for such a setting is that through the relative rotation of the two, the included angle between the handle assembly 100 and the main body 220 can be changed, so that the handle assembly 100 is lifted to a high position, enabling the user to hold the handle assembly 100 in a standing posture.

[0053] Further, at least a part of the first joint 11 of the joint assembly 10 is inserted into the main body 220 of the floor washer. The first joint 11 is provided with a disassembly button 331, so as to realize the detachable connection between the joint assembly 10 and the main body 220, and the user can disassemble the handle assembly 100 from the main body 220, which is convenient for the user to carry and maintain the handle assembly 100.

[0054] Specifically, the function of the telescopic assembly 20 provided in the embodiments of the present application is to extend the length of the handle assembly 100. The telescopic assembly 20 is arranged at the second joint 12 of the joint assembly 10. The telescopic assembly 20 has a contracted state and an extended state. Among them, the extended state of the telescopic assembly 20 is to solve the technical problem that the user needs to squat and bend down when the floor washer is used for flat-lying cleaning. After the joint assembly 10 changes the operation angle of the handle assembly 100, the telescopic assembly 20 can extend to a position where the user can operate the handle assembly 100 in a standing posture.

[0055] Specifically, the function of the locking mechanism 30 provided in the embodiments of the present application is to fix the telescopic assembly 20 so that the telescopic assembly 20 can maintain the telescopic state.

[0056] When the telescopic component 20 is in the extended state, then rotate the second joint 12 so that the included angle α with the first joint 11 is changed to 50° - 60°. In this way, the main body 220 of the floor washer can be in a lying flat and low posture, while the handle assembly 100 is in a high position for convenient user grip. The user controls the forward and backward movement and the twisting and turning of the floor washer through the handle assembly 100.

[0057] It should be noted that the specific structures of the telescopic component 20 and the locking mechanism 30 are not limited in the embodiments of the present application because the main improvement point of the present application is that the telescopic component 20 can be applicable to different cleaning spaces, so that the locking mechanism 30 can improve the technical effect of the working stability of the telescopic component 20. As for the specific structures of the telescopic component 20 and the locking mechanism 30, they can be set according to the type of the cleaning device 1000 and the actual use environment. For example, the telescopic component 20 can be set as a sleeve 21 component, or can also be set as a folding tube component. The locking mechanism 30 can be set as a mechanical manual mechanism, an electric mechanism, etc. These adjustments all belong to the protection scope of the embodiments of the present application.

[0058] The following Figures 1 to 9 embodiments are used to elaborate on the preferred embodiments of the specific structures of the telescopic component 20 and the locking mechanism 30.

[0059] As Figures 1 to 9 shown, in an alternative embodiment, the telescopic component 20 includes a sleeve 21 and a sliding tube 22. The sleeve 21 is sleeved on the second joint 12, and the sliding tube 22 is slidably sleeved on the sleeve 21. The sliding tube 22 has a contracted state of sliding to sleeve the rotating shaft 13 and an extended state of disengaging from the rotating shaft 13.

[0060] In this embodiment, the embodiments of the present application propose to realize the multi-angle use mode of the handle assembly 100 through the relative rotation of the second joint 12 and the first joint 11. At the same time, considering that the relative rotation of the second joint 12 and the first joint 11 may affect the requirement that the handle assembly 100 needs to be parallel to the main body 220 of the floor washer during normal cleaning, the embodiments of the present application propose that when the telescopic component 20 is in the contracted state, the sliding tube 22 will sleeve the rotating shaft 13 between the second joint 12 and the first joint 11, so that the second joint 12 and the first joint 11 cannot rotate relative to each other.

[0061] Furthermore, when the floor washer is in the normal use state and the telescopic component 20 is in the contracted state, a part of the sliding tube 22 is inserted into the main body 220 and is limited, so as to achieve the purpose that the handle assembly 100 and the main body 220 of the floor washer do not generate a rotation included angle.

[0062] Specifically, the sleeve 21 can be made of metal or plastic. The number of sleeves 21 is greater than 1 section, preferably 2 - 3 sections, so as to achieve the purpose of adjusting the length range of the telescopic component 20. The sleeve 21 is provided with fixing holes 222, and the sleeve 21 is fixed to the upper cover or the lower cover of the holding part 223 or both through the fixing holes 222. The sleeve 21 and the holding part 223 are preferably fixed by screws or rivets.

[0063] As Figures 1 to 9 shown, in some embodiments, the locking mechanism 30 includes a hook 31 and a clamping structure 32. One of the hook 31 and the clamping structure 32 is arranged on the sleeve 21, and the other of the hook 31 and the clamping structure 32 is arranged on the sliding tube 22. When the telescopic component 20 is in the contracted state, the hook 31 is clamped to the clamping structure 32.

[0064] In the above embodiments, arranging the hook 31 on the sleeve 21 and the clamping structure 32 on the sliding tube 22, as well as arranging the clamping structure 32 on the sleeve 21 and the hook 31 on the sliding tube 22, can both achieve the purpose of locking the sliding tube 22 and the sleeve 21. Therefore, both of these two embodiments fall within the protection scope of the embodiments of the present application.

[0065] Specifically, when the telescopic component 20 is in the contracted state, the sleeve 21 and the sliding tube 22 are clamped by the hook 31 and the clamping structure 32, so that the sliding tube 22 cannot slide relative to the sleeve 21. When it is necessary to unlock the telescopic component 20, the hook 31 and the clamping structure 32 are separated to unlock the telescopic component 20, enabling the telescopic component 20 to extend.

[0066] Next, the installation positions of the hook 31 and the clamping structure 32 will be described through some embodiments.

[0067] As Figures 1 to 9 shown, in some embodiments, the clamping structure 32 includes a clamping plate 321 arranged inside the sliding tube 22. The sleeve 21 is provided with a cantilever 311 extending into the sleeve 21. The hook 31 is arranged at the free end of the cantilever 311, and the hook 31 is provided with an inclined guiding portion facing the clamping plate 321.

[0068] In this embodiment, when the telescopic component 20 is in the contracted state, the hook 31 on the sleeve 21 is buckled on the clamping structure 32 of the sliding tube 22, so that the sliding tube 22 cannot slide relative to the sleeve 21. When it is necessary to unlock the telescopic component 20, the hook 31 on the sleeve 21 is separated from the clamping structure 32 of the sliding tube 22 to unlock the telescopic component 20, enabling the telescopic component 20 to extend.

[0069] Specifically, by disposing the hook 31 on the cantilever 311, during the docking process of the hook 31 and the clamping plate 321, the cantilever 311 can drive the hook 31 to cross over the clamping plate 321 and then be clamped to the clamping plate 321 through deformation, so as to achieve the purpose of relatively fixing the sleeve 21 and the slider.

[0070] Furthermore, the inclined guiding portion provided on the hook 31 enables the hook 31 to smoothly cross over the clamping plate 321 and then be clamped to the clamping plate 321, improving the assembly smoothness between the hook 31 and the clamping plate 321.

[0071] In addition, the cantilever 311 is provided with a connecting plug 312 assembled into the sleeve 21, and the handle assembly 100 further includes a connecting sleeve 313 embedded into the sleeve 21 and clamped to the connecting plug 312, which facilitates the user to disassemble the hook 31 and perform maintenance and replacement on the hook 31.

[0072] As Figures 1 to 9 shown, in some embodiments, the locking mechanism 30 further includes a button assembly 33. The button assembly 33 includes a button 331 and an elastic element 332. The button 331 is installed at a position corresponding to the hook 31 on the sliding tube 22 through the elastic element 332, and the button 331 is arranged to be able to press the hook 31 to disengage from the clamping plate 321.

[0073] In the above embodiment, the button assembly 33 of the locking mechanism 30 is arranged at the holding portion 223 of the sliding tube 22. When the telescopic assembly 20 is in a contracted state, the hook 31 on the sleeve 21 is buckled on the clamping structure 32 of the sliding tube 22, making the sliding tube 22 unable to slide relative to the sleeve 21; when it is necessary to unlock the telescopic assembly 20, press the button assembly 33, and the button 331 of the button assembly 33 presses on the hook 31 of the sleeve 21, causing the hook 31 to deform downward and then separate from the clamping structure 32 of the sliding tube 22, realizing the unlocking of the telescopic assembly 20 and enabling the telescopic assembly 20 to extend.

[0074] As Figures 1 to 9 shown, in some embodiments, the locking mechanism 30 further includes an elastic buckle 34. The elastic buckle 34 is installed on the sleeve 21, and the sliding tube 22 is provided with a positioning hole 221 that can be clamped to the elastic buckle 34. When the telescopic assembly 20 is in an extended state, the sliding tube 22 is clamped to the elastic buckle 34.

[0075] In this embodiment, when the telescopic assembly 20 is in an extended state, the positioning hole 221 of the sliding tube 22 is clamped to the elastic buckle 34 of the sleeve 21, making the sliding tube 22 and the sleeve 21 unable to move relative to each other. Then rotate the second joint 12 to change the included angle α between it and the first joint 11 to 50° - 60°. In this way, the main body 220 of the floor washer can be in a lying low position state, while the handle assembly 100 is in a high position for convenient user holding. The user controls the forward and backward movement and the twisting and turning of the floor washer through the handle assembly 100.

[0076] As Figures 1 to 9 shown, in some embodiments, both the sleeve 21 and the sliding tube 22 are configured as flat tubes. The sleeve 21 is circumferentially fixedly slidable relative to the sliding tube 22. The clamping plate 321 is disposed at the long axis end of the sliding tube 22, and the inclined guiding portion of the hook 31 faces the long axis end of the sliding tube 22.

[0077] In this embodiment, by configuring both the sleeve 21 and the sliding tube 22 as flat tubes, the phenomenon of circumferential rotation during the relative sliding of the sleeve 21 and the sliding tube 22 can be reduced, thereby reducing the misalignment phenomenon of the hook 31 and the clamping plate 321 caused by the circumferential rotation of the sleeve 21 and the sliding tube 22.

[0078] Furthermore, by configuring both the sleeve 21 and the sliding tube 22 as flat tubes, sufficient installation space and moving space can be provided for the hook 31 and the clamping plate 321, thereby reducing the phenomenon that the hook 31 cannot disengage from the clamping plate 321 due to the limitation of the moving space.

[0079] In an alternative embodiment, the telescopic assembly 20 includes a connecting rod and a folding rod. The connecting rod is connected to the second joint 12, and the folding rod is rotatably connected to the connecting rod. The folding rod has a contracted state folded to the connecting rod and an extended state unfolded relative to the connecting rod.

[0080] In this embodiment, the handle assembly 100 proposed in the present application solves the technical problem that the user needs to squat or bend down significantly when cleaning low positions with a flat-lying cleaning floor washer by using a telescopic and bendable handle assembly 100.

[0081] In addition, a switch button and a display panel are provided on the holding portion 223 of the sleeve 21. The handle assembly 100 controls the start and stop of the cleaning device 1000 and the switching of the working mode through the switch button.

[0082] As Figures 1 to 9 shown, in a second aspect, the present application provides a cleaning device 1000. The cleaning device 1000 includes a cleaning assembly 200 and a handle assembly 100 according to the second aspect of the present application. The handle assembly 100 is connected to the cleaning assembly 200 through a joint assembly 10.

[0083] In this embodiment, the cleaning device 1000 proposed in the present application has all the technical effects of the handle assembly 100, and will not be elaborated in detail herein.

[0084] As Figures 1 to 9As shown, in some embodiments, the cleaning assembly 200 includes a floor brush 210 and a main body 220. The main body 220 is rotatably connected to the floor brush 210. The first joint 11 of the joint assembly 10 is connected to the main body 220, and the main body 220 can be in a lying state or an upright state under the drive of the joint assembly 10.

[0085] In this embodiment, the main components of the main body 220 of the cleaning assembly 200 include a sewage tank and a vacuum motor. Its working principle is as follows: The water pump pumps the water in the clean water tank of the cleaning assembly 200 to the roller brush of the floor brush 210 to wet the roller brush, and the rotation of the roller brush achieves the purpose of cleaning. The vacuum motor in the main body 220 generates suction, and the sewage is sucked into the pipeline through the suction port on the floor brush 210 and sent to the sewage tank.
