Description

Technical Field

[0001] The present invention relates to the technical field of cleaning devices, and more precisely, to a surface cleaning device. Background Art

[0002] A surface cleaning device is a device capable of cleaning debris or dirt on a surface, which includes fabric-covered surfaces such as carpets and ornaments, as well as exposed surfaces such as hardwood, linoleum, vinyl, and tiles. However, most of the current cleaning devices on the market can only meet one usage scenario. For example, an upright cleaning device can only clean the floor or carpets on the ground, and cannot clean desks above the ground; a handheld cleaning device can be used to clean desks, car interiors, etc. above the ground. However, if you want to clean the floor or carpet, the user needs to squat down to operate the device, and the long-term usage experience is poor; and if you want to meet multi-scenario usage, the user needs to purchase multiple cleaning devices, which imposes a certain burden on the user's economy and storage space.

[0003] Therefore, as disclosed in the invention patent with the publication number: CN116269066A, a cleaning device is disclosed, including: a body; a fluid recovery system, including a fluid recovery container and a suction pipeline; a floor brush, including a suction port, the suction port can be in fluid communication with the fluid recovery system, and the floor brush is connected to the body; an accessory, including a dirt suction pipeline, the dirt suction pipeline can be in fluid communication with the fluid recovery container, and the user can hold the accessory to suck dirt; a first control valve assembly, arranged between the suction pipeline and the suction port and the dirt suction pipeline, the first control valve assembly is used to control the suction pipeline to selectively communicate with the suction port or the dirt suction pipeline, so that the cleaning device can switch between the floor brush mode and the accessory mode. In this technical solution, by adding an accessory to the existing upright cleaning device, the user can hold the accessory to suck dirt, meeting the multi-scenario usage requirements of the cleaning device. The cleaning device switches between the floor brush mode and the accessory mode through the first control valve assembly. In this technical solution, the first control valve assembly further includes an operation part, and the user needs to manually control the operation part to rotate so that the valve core moves between a first position and a second position. The operation part is arranged on the floor brush, and the user needs to squat or bend down during operation, and the usage experience is poor. Moreover, by manually operating to switch between the floor brush mode and the accessory mode, the user is prone to forget and thus unable to achieve function switching, and the specific use is still relatively inconvenient. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a surface cleaning device, which can automatically switch between the floor brush mode and the accessory mode according to the user's usage state through a driving component, without manual operation by the user, and has a better usage experience.

[0005] The present invention provides a surface cleaning device, including a body, on which a floor brush assembly and a handheld accessory are mounted. A sewage tank is provided inside the body. The floor brush assembly is provided with a first suction port, and the handheld accessory is provided with a second suction port. A first air duct is provided between the first suction port and the sewage tank, and a second air duct is provided between the second suction port and the sewage tank. A sealing rotating member is provided at the junction of the first air duct, the second air duct and the sewage tank. The sealing rotating member rotates to switch the connection between the first air duct or the second air duct and the sewage tank. The body is rotatably connected to the floor brush assembly, and a driving assembly for driving the sealing rotating member to rotate is provided between the body and the floor brush assembly. When the body is in an upright state relative to the floor brush assembly, the driving assembly is in an initial state, and the sealing rotating member connects the second air duct to the sewage tank and blocks the first air duct, so that the handheld accessory is in a use state. When the body rotates to an inclined state relative to the floor brush assembly, the driving assembly is forced to drive the sealing rotating member to rotate, and the sealing rotating member connects the first air duct to the sewage tank and blocks the second air duct, so that the floor brush assembly is in a use state.

[0006] In this technical solution, the floor brush assembly and the handheld accessory are mounted on the body. The body can clean the ground, carpets located on the ground, etc. through the floor brush assembly, and can clean the tabletop, sofa, curtain, car interior, etc. above the ground through the handheld accessory. By providing a sewage tank inside the body, the floor brush assembly is connected to the sewage tank through the first suction port, so that dust and sewage on the surface of the ground or carpet can be sucked into the sewage tank through the first suction port for collection. By providing a first air duct between the first suction port and the sewage tank, dust and sewage on the surface of the ground or carpet can sequentially enter the first air duct through the first suction port and then enter the sewage tank for collection, improving the air suction efficiency. The handheld accessory is connected to the sewage tank through the second suction port, so that dust and sewage on the surface of the tabletop, sofa, curtain, car interior, etc. can be sucked into the sewage tank through the second suction port for collection. By providing a second air duct between the second suction port and the sewage tank, dust and sewage on the surface of the tabletop, sofa, curtain, car interior, etc. can sequentially enter the second air duct through the second suction port and then enter the sewage tank for collection, improving the air suction efficiency;

[0007] In actual use, the floor brush assembly and the handheld accessory are often used separately. Therefore, the first air duct and the second air duct need to be switched to connect with the sewage tank. By providing a rotatable sealing rotating member at the junction of the first air duct, the second air duct and the sewage tank, the connection between the first air duct and the sewage tank or the second air duct and the sewage tank is switched by the rotation of the sealing rotating member. When the handheld accessory needs to be used, the sealing rotating member rotates to block the first air duct, so that the second air duct is connected to the sewage tank, and dust and sewage can be collected into the sewage tank through the second suction port via the second air duct, with a relatively high air suction efficiency. When the floor brush assembly needs to be used, the sealing rotating member rotates to the second air duct, so that the first air duct is connected to the sewage tank, and dust and sewage can be collected into the sewage tank through the first suction port via the first air duct, with a relatively high air suction efficiency;

[0008] When actually using the floor brush assembly, users mostly push the body to move the floor brush assembly on the surface to be cleaned. In this solution, the body is rotatably connected to the floor brush assembly, enabling users to tilt the body when using the floor brush assembly. Compared with the height of the upright body, the body in this solution can rotate according to the user's height or usage habit when pushing the floor brush assembly. The tilted body is more suitable for different users. Pushing the floor brush assembly with the tilted body is more labor-saving, and it is more smooth for users to apply force to the tilted body, providing a better user experience.

[0009] By providing a driving assembly that drives the sealing rotating member to rotate between the body and the floor brush assembly, when the body is in an upright state relative to the floor brush assembly, which is the initial state at this time, the floor brush assembly is in an unusable state and the handheld accessory is in a usable state. The driving assembly is not stressed, so the sealing rotating member does not rotate, and the sealing rotating member blocks the first air duct, causing the second air duct to communicate with the sewage tank. Users can use the handheld accessory to clean the dust and sewage on the surfaces such as the tabletop, sofa, curtain, and car interior. When the body is in a tilted state relative to the floor brush assembly, the floor brush assembly is in a usable state and the handheld accessory is in an unusable state at this time. The driving assembly is subjected to the acting force of the rotation of the body and thus drives the sealing rotating member to rotate. The sealing rotating member blocks the second air duct through rotation, causing the first air duct to communicate with the sewage tank. Users can use the floor brush assembly to clean the dust and sewage on the surfaces such as the floor or carpet. Users only need to adjust the body according to the actual usage requirements to automatically switch between the floor brush mode and the accessory mode. When they need to use the floor brush assembly for cleaning, users will casually tilt the body, causing the whole machine to automatically switch to the floor brush mode. When they need to use the handheld accessory for cleaning, users do not need to tilt the body, and the body is in an upright state relative to the floor brush assembly, causing the whole machine to automatically switch to the accessory mode without the need for additional manual operation by the user, providing a better user experience.

[0010] As an improvement, the driving assembly includes a fixed gear, a first transmission gear, and a second transmission gear. The fixed gear is installed on the floor brush assembly, the first transmission gear is rotatably installed on the body, the second transmission gear is installed on the sealing rotating member. One side of the first transmission gear is in transmission connection with the fixed gear, and the other side of the first transmission gear is in transmission connection with the second transmission gear. When the body rotates relative to the floor brush assembly, the first transmission gear rotates on the fixed gear and drives the second transmission gear to rotate, causing the second transmission gear to drive the sealing rotating member to rotate.

[0011] In this technical solution, the driving component is set to be composed of a fixed gear, a first transmission gear, and a second transmission gear. Among them, the first transmission gear is installed on the body, the second transmission gear is installed on the sealed rotating part, the first transmission gear and the second transmission gear are meshed and driven. When the body rotates, it drives the first transmission gear to rotate synchronously. The first transmission gear drives the second transmission gear to rotate through rotation, and the second rotating gear drives the sealed rotating part to rotate through rotation. Thus, when the body rotates relative to the floor brush assembly, the floor brush mode or the accessory mode can be automatically switched through the driving component. Considering that the sealed rotating part needs to exactly block the first air duct or the second air duct, when the second transmission gear exactly rotates to the first air duct opening or the second air duct opening, it needs to stop rotating. Since the first transmission gear is installed on the body and the rotation angle of the first transmission gear changes with the body, the second transmission gear needs to stop driving before the first transmission gear, that is, the second transmission gear and the first transmission gear need to be disengaged from each other. In this solution, a fixed gear linked to the first transmission gear is installed on the floor brush assembly. Through the fixed gear, the first transmission gear can continue to rotate along a preset trajectory after being disengaged from the second transmission gear.

[0012] When the body rotates and tilts relative to the floor brush assembly, the body drives the first transmission gear to rotate, thereby driving the second transmission gear to drive the sealed rotating part to rotate to block the second air duct. At this time, the first transmission gear and the second transmission gear are disengaged, so that the sealed rotating part connects the first air duct and the sewage outlet, and the floor brush assembly is in a usable state. The first transmission gear continues to rotate randomly with the body along the fixed gear. When the body rotates and resets relative to the floor brush assembly, the body drives the first transmission gear to rotate back to its original position. The first transmission gear rotates back to its original position along the fixed gear and meshes with the second transmission gear, so that the first transmission gear can drive the second transmission gear to drive the sealed rotating part to rotate to block the first air duct, and the sealed rotating part connects the second air duct and the sewage outlet, and the handheld accessory is in a usable state. The driving component has a simple structure, a relatively high transmission efficiency, and a reliable gear transmission structure and a long service life.

[0013] As an improvement, a hollow connecting seat is installed in the body. The connecting seat is provided with a first interface, a second interface, and a third interface. The first interface is communicated with the first air duct, the second interface is communicated with the second air duct, and the third interface is communicated with the sewage tank. The sealed rotating part is rotatably installed on the connecting seat, and the sealed rotating part switches the connection between the first interface and the third interface or the connection between the second interface and the third interface through rotation.

[0014] In this technical solution, a connection base is arranged inside the machine body. A first interface, a second interface, and a third interface are arranged on the connection base. The connection base is communicated with a first air duct through the first interface, the connection base is communicated with a second air duct through the second interface, and the connection base is communicated with a sewage tank through the third interface. The first air duct, the second air duct, and the sewage tank are communicated through the connection base. A sealing rotary member can be rotatably installed in the connection base to switch between the floor brush mode or the accessory mode. The installation structure is simple and reliable. The sealing rotary member can block the first interface or the second interface by rotating in the connection base, so as to block the first air duct or the second air duct, which is beneficial to improving the overall sealing performance.

[0015] As an improvement, a sealing ring is sleeved on the sealing rotary member, and the sealing rotary member is hermetically connected to the inner wall of the connection base through the sealing ring. In this technical solution, the sealing rotary member blocks the first interface or the second interface by rotating. By sleeving a sealing ring on the sealing rotary member, the joint between the sealing rotary member and the connection base is hermetically joined through the sealing ring, improving the sealing performance of the sealing rotary member, thereby improving the air suction cleaning efficiency.

[0016] As an improvement, a water tank is arranged inside the machine body. A first water channel is arranged between the floor brush assembly and the water tank, and the water tank supplies water to the floor brush assembly through the first water channel. A second water channel is arranged between the handheld accessory and the water tank, and the water tank supplies water to the handheld accessory through the second water channel.

[0017] In this technical solution, the water tank is installed inside the machine body, and a mixed liquid of water and a cleaning agent is contained in the water tank. The floor brush assembly is communicated with the water tank through the first water channel, and the handheld accessory is communicated with the water tank through the second water channel. The water tank can supply the cleaning mixed liquid to the floor brush assembly through the first water channel. The floor brush assembly can better clean carpets, etc. by spraying the cleaning mixed liquid. The water tank can supply the cleaning mixed liquid to the handheld accessory through the second water channel. The handheld accessory can better clean sofas, curtains, etc. by spraying the cleaning mixed liquid, which is beneficial to improving the cleaning efficiency and can meet the multi-scenario use requirements of the cleaning equipment.

[0018] As an improvement, a sealing piston is arranged at the joint of the first water channel, the second water channel, and the water tank. A connecting rod is arranged between the sealing piston and the sealing rotary member. The sealing rotary member drives the sealing piston to move synchronously through the connecting rod when rotating, and the sealing piston switches the connection between the first water channel and the water tank or the connection between the second water channel and the water tank.

[0019] In the present technical solution, the floor brush assembly and the handheld attachment are used separately, so the first water channel and the second water channel need to be switched to be connected with the clean water tank, and a sealing piston is provided at the junction of the first water channel, the second water channel and the clean water tank, and the sealing piston is moved back and forth to switch the first water channel to be connected with the clean water tank or the second water channel to be connected with the clean water tank, and a connecting rod is provided between the sealing piston and the sealing rotating part, and the sealing piston and the sealing rotating part are linked by the connecting rod, so that when the sealing rotating part rotates, the sealing piston can be driven to move by the connecting rod, and when the machine body is in an upright state relative to the floor brush assembly, the driving assembly is not subjected to force, and the sealing rotating part is blocked. The first air duct is blocked, so that the second air duct is connected to the sewage tank, the connecting rod is not subjected to force, and the sealing piston blocks the first water channel, so that the second water channel is connected to the clean water tank. At this time, the handheld accessory is in a usable state. When the body is in a tilted state relative to the floor brush assembly, the driving assembly is forced to drive the sealing rotating part to rotate and block the second air duct, so that the first air duct is connected to the sewage tank. The sealing rotating part rotates to drive the connecting rod to move, and the connecting rod is forced to drive the sealing piston to move and block the second water channel, so that the first water channel is connected to the clean water tank. At this time, the floor brush assembly is in a usable state, the linkage structure is simple and efficient, the user does not need to manually adjust, and the user experience is better.

[0020] As an improvement, a first linkage member is provided between the connecting rod and the sealing rotating member, and the sealing rotating member is provided with a cam adapted to the first linkage member. The sealing rotating member rotates to drive the first linkage member to move up and down through the cam, so that the first linkage member drives the connecting rod to move synchronously.

[0021] In the present technical solution, the sealing rotating part is linked to the sealing piston through a connecting rod. A first linkage part is arranged between the connecting rod and the sealing rotating part. A cam that can drive the first linkage part to move up and down is provided on the sealing rotating part. When the sealing rotating part rotates, the cam abuts or disengages from the first linkage part, thereby driving the first linkage part to move up and down. The first linkage part can drive the connecting rod to move synchronously, so that the connecting rod can drive the sealing piston to move. The linkage structure is ingenious and efficient, and the cam is arranged on the sealing rotating part. There is no need to arrange an additional driving structure, which will not increase the overall size. In addition, the first linkage part and the connecting rod both move up and down, so that the distribution of the linkage structure is more reasonable.

[0022] As an improvement, a connecting valve is installed in the body, and the connecting valve is provided with a first water inlet, a first water outlet and a second water outlet. The first water inlet is connected to a clean water tank, the first water outlet is connected to a first water channel, and the second water outlet is connected to a second water channel. The sealing piston is slidably installed in the connecting valve, and the sealing piston switches the first water outlet to be connected to the first water inlet or the second water outlet to be connected to the first water inlet by sliding.

[0023] In this technical solution, a connection valve is provided inside the machine body. The connection valve is provided with a first water inlet, a first water outlet and a second water outlet. The connection valve is communicated with the clean water tank through the first water inlet, the connection valve is communicated with the first water channel through the first water outlet, and the connection valve is communicated with the second water channel through the second water outlet. The first water channel, the second water channel and the clean water tank are communicated through the connection valve. The sealing piston can be slidably installed in the connection valve to switch between the floor brush mode or the accessory mode. The installation structure is simple and reliable. The sealing piston can block the first water outlet or the second water outlet by sliding in the connection valve, so as to block the first water channel or the second water channel, and the structure is simple and reliable.

[0024] As an improvement, a second linkage is slidably installed in the connection valve. One end of the second linkage abuts against the sealing piston, and the other end of the second linkage abuts against the connecting rod. The connecting rod drives the sealing piston to slide in the connection valve through the second linkage.

[0025] In this technical solution, by slidably installing a second linkage in the connection valve, the sealing piston and the connecting rod are linked through the second linkage. When the machine body is in an upright state relative to the floor brush assembly, neither the sealing rotating part nor the connecting rod is stressed, and the sealing piston blocks the first water channel, so that the second water channel is communicated with the clean water tank. At this time, the hand-held accessory is in a usable state. When the machine body rotates to an inclined state relative to the floor brush assembly, the sealing piston rotates under the action of the driving component. The sealing piston drives the first linkage to slide upward through the cam. The first linkage drives the connecting rod to slide upward synchronously. The connecting rod slides upward to push the second linkage, and the second linkage is stressed to drive the sealing piston to slide to block the second water channel, so that the first water channel is communicated with the clean water tank. At this time, the floor brush assembly is in a usable state. The linkage structure is simple and efficient, and the user does not need to manually adjust, and the use experience is better.

[0026] As an improvement, the end of the second linkage abutting against the connecting rod is provided with a first guiding inclined surface, and the connecting rod is provided with a second guiding inclined surface adapted to the first guiding inclined surface. The connecting rod drives the second linkage to slide in the connection valve through the cooperation of the first guiding inclined surface and the second guiding inclined surface. In this technical solution, by providing a first guiding inclined surface on the second linkage and a second guiding inclined surface on the connecting rod, through the cooperation of the first guiding inclined surface and the second guiding inclined surface, when the connecting rod slides upward, it can push the second linkage to slide in the connection valve. The transmission cooperation structure is simple and reliable. On the other hand, the transmission through the cooperation of the first guiding inclined surface and the second guiding inclined surface will not increase the overall volume of the transmission structure and will not increase the overall size of the whole machine.

[0038] To better understand the present application, more detailed descriptions of various aspects of the present application will be made with reference to the accompanying drawings. It should be understood that these detailed descriptions are only descriptions of exemplary embodiments of the present application and do not limit the scope of the present application in any way. Throughout the specification, the same reference numerals refer to the same elements.

[0039] In the drawings, for ease of illustration, the thickness, dimensions, and shape of the objects have been slightly exaggerated. The drawings are for illustrative purposes only and are not drawn to scale.

[0040] It should also be understood that the terms "comprising", "including", "having", "containing", "including", when used in this specification, denote the presence of the stated features, integers, steps, operations, elements, and / or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and / or combinations thereof.

[0041] As Figures 1 to 9 shown, the present application discloses a surface cleaning device, including a body 1, on which a floor brush assembly 2 and a hand-held accessory 3 are mounted. The body 1 is provided with the floor brush assembly 2 and the hand-held accessory 3. Through the floor brush assembly 2, the body 1 can clean the floor, carpets, etc. located on the floor. Through the hand-held accessory 3, the body 1 can clean desks, sofas, curtains, car interiors, etc. above the floor. A sewage tank 11 is provided inside the body 1. The floor brush assembly 2 is provided with a first suction port 21, and the hand-held accessory 3 is provided with a second suction port 31. A first air duct 22 is provided between the first suction port 21 and the sewage tank 11, and a second air duct 32 is provided between the second suction port 31 and the sewage tank 11. By providing the sewage tank 11 inside the body 1, the floor brush assembly 2 is communicated with the sewage tank 11 through the first suction port 21, so that dust and sewage on the surface of the floor or carpet can be sucked into the sewage tank 11 through the first suction port 21 for collection. By providing the first air duct 22 between the first suction port 21 and the sewage tank 11, dust and sewage on the surface of the floor or carpet can sequentially enter the first air duct 22 through the first suction port 21 and then enter the sewage tank 11 for collection, improving the air suction efficiency. The hand-held accessory 3 is communicated with the sewage tank 11 through the second suction port 31, so that dust and sewage on the surfaces of desks, sofas, curtains, car interiors, etc. can be sucked into the sewage tank 11 through the second suction port 31 for collection. By providing the second air duct 32 between the second suction port 31 and the sewage tank 11, dust and sewage on the surfaces of desks, sofas, curtains, car interiors, etc. can sequentially enter the second air duct 32 through the second suction port 31 and then enter the sewage tank 11 for collection, improving the air suction efficiency;

[0042] A sealing rotary member 4 is provided at the joint of the first air duct 22, the second air duct 32 and the sewage tank 11. The sealing rotary member 4 switches the connection between the first air duct 22 or the second air duct 32 and the sewage tank 11 by rotating. In actual use, the floor brush assembly 2 and the handheld accessory 3 are often used separately. Therefore, the first air duct 22 and the second air duct 32 need to be switched to connect with the sewage tank 11. By providing a rotatable sealing rotary member 4 at the joint of the first air duct 22, the second air duct 32 and the sewage tank 11, the connection between the first air duct 22 and the sewage tank 11 or the connection between the second air duct 32 and the sewage tank 11 is switched by rotating the sealing rotary member 4. When the handheld accessory 3 needs to be used, the sealing rotary member 4 rotates to block the first air duct 22, so that the second air duct 32 is connected to the sewage tank 11, and dust and sewage can be collected into the sewage tank 11 through the second air inlet 31 via the second air duct 32, and the air suction efficiency is relatively high. When the floor brush assembly 2 needs to be used, the sealing rotary member 4 rotates to the second air duct 32, so that the first air duct 22 is connected to the sewage tank 11, and dust and sewage can be collected into the sewage tank 11 through the first air inlet 21 via the first air duct 22, and the air suction efficiency is relatively high;

[0043] The body 1 is rotatably connected to the floor brush assembly 2. In actual use of the floor brush assembly 2, users mostly push the body 1 to move the floor brush assembly 2 on the surface to be cleaned. In this solution, the body 1 is rotatably connected to the floor brush assembly 2, so that the user can tilt the body 1 when using the floor brush assembly 2. Compared with the height of the upright body 1, the body 1 in this solution can rotate according to the user's height or usage habit when pushing the floor brush assembly 2. The tilted body 1 is more suitable for different users to use. Pushing the floor brush assembly 2 with the tilted body 1 is more labor-saving, and it is more smooth for the user to apply force to the tilted body 1, and the use experience is better;

[0044] A drive assembly 5 for driving the sealing rotary member 4 to rotate is provided between the body 1 and the floor brush assembly 2. By providing the drive assembly 5 for driving the sealing rotary member 4 to rotate between the body 1 and the floor brush assembly 2, when the body 1 is in an upright state relative to the floor brush assembly 2, which is the initial state at this time, the floor brush assembly 2 is in a non-usable state and the hand-held accessory 3 is in a usable state. The drive assembly 5 is not stressed, so the sealing rotary member 4 does not rotate. The sealing rotary member 4 blocks the first air duct 22, making the second air duct 32 communicate with the sewage tank 11. Users can use the hand-held accessory 3 to clean the dust and sewage on the surfaces such as the tabletop, sofa, curtain, and car interior. When the body 1 is in an inclined state relative to the floor brush assembly 2, the floor brush assembly 2 is in a usable state and the hand-held accessory 3 is in a non-usable state at this time. The drive assembly 5 is driven by the acting force of the rotation of the body 1 to drive the sealing rotary member 4 to rotate. The sealing rotary member 4 blocks the second air duct 32 by rotating, making the first air duct 22 communicate with the sewage tank 11. Users can use the floor brush assembly 2 to clean the dust and sewage on the surfaces such as the ground or carpet. Users only need to adjust the body 1 according to the actual use requirements to automatically realize the floor brush mode and the accessory mode. When the floor brush assembly 2 needs to be used for cleaning, the user will tilt the body 1 conveniently, so that the whole machine automatically switches to the floor brush mode. When the hand-held accessory 3 needs to be used for cleaning, the user does not need to tilt the body 1. The body 1 is in an upright state relative to the floor brush assembly 2, making the whole machine automatically switch to the accessory mode without additional manual operation by the user, and the use experience is better.

[0045] More specifically, the drive assembly 5 includes a fixed gear 51, a first transmission gear 52, and a second transmission gear 53. The fixed gear 51 is installed on the floor brush assembly 2, the first transmission gear 52 is rotatably installed on the body 1, and the second transmission gear 53 is installed on the sealing rotary member 4. One side of the first transmission gear 52 is in transmission connection with the fixed gear 51, and the other side of the first transmission gear 52 is in transmission connection with the second transmission gear 53. The first transmission gear 52 and the second transmission gear 53 are in meshing transmission. When the body 1 rotates, it drives the first transmission gear 52 to rotate synchronously. The first transmission gear 52 drives the second transmission gear 53 to rotate through rotation, and the second transmission gear drives the sealing rotary member 4 to rotate through rotation, so that when the body 1 rotates relative to the floor brush assembly 2, the floor brush mode or the accessory mode can be automatically switched through the drive assembly 5. Considering that the sealing rotary member 4 needs to exactly block the first air duct 22 or the second air duct 32, when the second transmission gear 53 exactly rotates to the opening of the first air duct 22 or the second air duct 32, it needs to stop rotating. Since the first transmission gear 52 is installed on the body 1 and the rotation angle of the first transmission gear 52 changes with the body 1, the second transmission gear 53 needs to stop driving before the first transmission gear 52, that is, the second transmission gear 53 and the first transmission gear 52 need to be disengaged from each other. In this solution, a fixed gear 51 linked to the first transmission gear 52 is installed on the floor brush assembly 2, so that after the first transmission gear 52 and the second transmission gear 53 are disengaged, the first transmission gear 52 can still continue to rotate along a preset trajectory through the fixed gear 51;

[0046] When the body 1 rotates and tilts relative to the floor brush assembly 2, the body 1 drives the first transmission gear 52 to rotate, thereby driving the second transmission gear 53 to drive the sealing rotary member 4 to rotate to block the second air duct 32. At this time, the first transmission gear 52 and the second transmission gear 53 are disengaged, so that the sealing rotary member 4 connects the first air duct 22 and the sewage outlet, and the floor brush assembly 2 is in a usable state. The first transmission gear 52 continues to rotate randomly with the body 1 along the fixed gear 51. When the body 1 rotates and resets relative to the floor brush assembly 2, the body 1 drives the first transmission gear 52 to rotate and reset. The first transmission gear 52 rotates and resets along the fixed gear 51 and meshes with the second transmission gear 53, so that the first transmission gear 52 can drive the second transmission gear 53 to drive the sealing rotary member 4 to rotate to block the first air duct 22, and the sealing rotary member 4 connects the second air duct 32 and the sewage outlet, and the hand-held accessory 3 is in a usable state. The drive assembly 5 has a simple structure, a relatively high transmission efficiency, and a reliable gear transmission structure and a long service life.

[0047] More specifically, a hollow connecting seat 12 is installed inside the body 1. The connecting seat 12 is provided with a first interface 121, a second interface 122, and a third interface 123.

The first air duct 22, the second air duct 32, and the sewage tank 11 are communicated through the connecting seat 12. The sealing rotary member 4 is rotatably installed on the connecting seat 12. The sealing rotary member 4 can switch between the brush mode or the accessory mode by rotation. The installation structure is simple and reliable. The sealing rotary member 4 can block the first interface 121 or the second interface 122 by rotating inside the connecting seat 12, so as to block the first air duct 22 or the second air duct 32, which is beneficial to improving the overall sealing performance.

[0048] More specifically, a sealing ring 41 is sleeved on the sealing rotary member 4. The sealing rotary member 4 is hermetically connected to the inner wall of the connecting seat 12 through the sealing ring 41. The sealing rotary member 4 blocks the first interface 121 or the second interface 122 by rotation. By sleeving the sealing ring 41 on the sealing rotary member 4, the joint between the sealing rotary member 4 and the connecting seat 12 is hermetically joined through the sealing ring 41, improving the sealing performance of the sealing rotary member 4, thereby improving the air suction cleaning efficiency.

[0049] More specifically, a water tank 13 is provided inside the body 1. A first water channel is provided between the floor brush assembly 2 and the water tank 13.

[0050] More specifically, a sealing piston 6 is provided at the joint of the first water channel, the second water channel and the clean water tank 13. A connecting rod 7 is provided between the sealing piston 6 and the sealing rotating member 4. When the sealing rotating member 4 rotates, it drives the sealing piston 6 to move synchronously through the connecting rod 7. The sealing piston 6 switches the connection between the first water channel and the clean water tank 13 or the connection between the second water channel and the clean water tank 13. The floor brush assembly 2 and the handheld accessory 3 are used separately. Therefore, the first water channel and the second water channel need to be switched to be connected to the clean water tank 13. By providing the sealing piston 6 at the joint of the first water channel, the second water channel and the clean water tank 13, the sealing piston 6 moves back and forth to switch the connection between the first water channel and the clean water tank 13 or the connection between the second water channel and the clean water tank 13. By providing the connecting rod 7 between the sealing piston 6 and the sealing rotating member 4, the connecting rod 7 links the sealing piston 6 and the sealing rotating member 4, so that when the sealing rotating member 4 rotates, it can drive the sealing piston 6 to move through the connecting rod 7.

The rotation of the sealing rotating member 4 drives the connecting rod 7 to move. The connecting rod 7 is stressed to drive the sealing piston 6 to move and block the second water channel, so that the first water channel is connected to the clean water tank 13. At this time, the floor brush assembly 2 is in a usable state. The linkage structure is simple and efficient, and the user does not need to manually adjust, so the use experience is better.

[0051] More specifically, a first linkage 8 is provided between the connecting rod 7 and the sealing rotating member 4. The sealing rotating member 4 is provided with a cam 42 adapted to the first linkage 8. When the sealing rotating member 4 rotates, it drives the first linkage 8 to move up and down through the cam 42, so that the first linkage 8 drives the connecting rod 7 to move synchronously.

By providing the first linkage 8 between the connecting rod 7 and the sealing rotating member 4, and the sealing rotating member 4 is provided with a cam 42 capable of driving the first linkage 8 to move up and down. When the sealing rotating member 4 rotates, it abuts against or disengages from the first linkage 8 through the cam 42, thereby driving the first linkage 8 to move up and down. The first linkage 8 can drive the connecting rod 7 to move synchronously, so that the connecting rod 7 can drive the sealing piston 6 to move. The linkage structure is ingenious and efficient. Moreover, the cam 42 is provided on the sealing rotating member 4, and no additional driving structure needs to be provided, so the overall size will not be increased. Both the first linkage 8 and the connecting rod 7 move up and down, so that the distribution of the linkage structure is relatively reasonable.

[0052] More specifically, a connection valve 14 is installed in the body 1. The connection valve 14 is provided with a first water inlet 141, a first water outlet 142, and a second water outlet 143. The first water inlet 141 is communicated with the clean water tank 13, the first water outlet 142 is communicated with the first water channel, and the second water outlet 143 is communicated with the second water channel. The sealing piston 6 is slidably installed in the connection valve 14. The sealing piston 6 slides to switch the communication between the first water outlet 142 and the first water inlet 141 or the communication between the second water outlet 143 and the first water inlet 141. By providing the connection valve 14 in the body 1, the connection valve 14 is provided with the first water inlet 141, the first water outlet 142, and the second water outlet 143.

[0053] More specifically, a second linkage 9 is slidably installed in the connection valve 14. One end of the second linkage 9 abuts against the sealing piston 6, and the other end of the second linkage 9 abuts against the connecting rod 7. The connecting rod 7 drives the sealing piston 6 to slide in the connection valve 14 through the second linkage 9. By slidably installing the second linkage 9 in the connection valve 14 and linking the sealing piston 6 and the connecting rod 7 through the second linkage 9, when the body 1 is in an upright state relative to the floor mopping assembly 2, neither the sealing rotating member 4 nor the connecting rod 7 is stressed, and the sealing piston 6 blocks the first water channel, so that the second water channel is communicated with the clean water tank 13. At this time, the hand-held attachment 3 is in a usable state. When the body 1 rotates and is in an inclined state relative to the floor mopping assembly 2, the sealing piston 6 is driven to rotate by the driving assembly 5. The sealing piston 6 drives the first linkage 8 to slide upward through the cam 42. The first linkage 8 drives the connecting rod 7 to slide upward synchronously. The connecting rod 7 slides upward to push the second linkage 9, and the second linkage 9 is stressed to drive the sealing piston 6 to slide to block the second water channel, so that the first water channel is communicated with the clean water tank 13. At this time, the floor mopping assembly 2 is in a usable state. The linkage structure is simple and efficient, and the user does not need to manually adjust, and the use experience is better.
