Description

Surface cleaning equipment Technical Field

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

[0002] A surface cleaning device is a device that can clean debris or dirt from surfaces, including fabric-covered surfaces such as carpets and upholstery, as well as bare surfaces such as hardwood, linoleum, vinyl, and tile. However, most cleaning devices currently available on the market can only meet one usage scenario. For example, upright cleaning devices can only clean floors or carpets on the floor, but cannot clean tables above the floor. Handheld cleaning devices can be used to clean tables above the floor, car interiors, etc., but to clean floors or carpets, users need to squat to operate the device, which makes long-term use less user-friendly. Furthermore, to meet multiple usage scenarios, users need to purchase multiple cleaning devices, which places a certain burden on the user's finances and storage space.

[0003] Therefore, the invention patent with publication number: CN116269066A discloses a cleaning device, including: a body; a fluid recovery system, including a fluid recovery container and a suction pipe; a floor brush, including a suction port, which can be fluidically connected to the fluid recovery system, and the floor brush is connected to the body; an accessory, including a sewage suction pipe, which can be fluidically connected to the fluid recovery container, and the user can hold the accessory to suck dirt; a first control valve assembly, which is arranged between the suction pipe and the suction port and the sewage suction pipe, and the first control valve assembly is used to control the suction pipe to selectively connect with the suction port or the sewage suction pipe, 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 equipment, the user can hold the accessory to suck out dirt, meeting the needs of using the cleaning equipment in multiple scenarios. The cleaning equipment switches the floor brush mode and the accessory mode through the first control valve assembly. The first control valve assembly in this technical solution also includes an operating part. The user needs to manually control the rotation of the operating part to move the valve core between the first position and the second position. The operating part is set on the floor brush. The user needs to squat or bend down when operating, and the user experience is poor. In addition, when manually operating to switch between the floor brush mode and the accessory mode, the user is likely to forget and cannot achieve function switching, and the specific use is still relatively inconvenient. Technical issues

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

[0005] The present invention provides a surface cleaning device, comprising a body, a floor brush assembly and a hand-held accessory are installed on the body, a sewage tank is provided in the body, the floor brush assembly is provided with a first suction port, and the hand-held 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, and a sealing rotating part is provided at the junction of the first air duct, the second air duct and the sewage tank, and the sealing rotating part switches the first air duct or the second air duct to be connected to the sewage tank by rotation, the body is rotatably connected to the floor brush assembly, and a driving assembly for driving the sealing rotating part 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, the sealing rotating part connects the second air duct and the sewage tank and blocks the first air duct, so that the hand-held accessory is in use state, and 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 the sealing rotating part connects the first air duct and the sewage tank and blocks the second air duct, so that the floor brush assembly is in use state.

[0006] In the present technical solution, a floor brush assembly and a handheld accessory are installed on the machine body. The machine body can clean the floor or the carpet on the floor through the floor brush assembly, and the machine body can clean the table, sofa, curtain, car interior, etc. above the floor through the handheld accessory. By arranging a sewage tank in the machine body, the floor brush assembly is connected with the sewage tank through a first suction port, so that dust and sewage on the surface of the floor or carpet can be sucked into the sewage tank through the first suction port for collection. By arranging a first air duct between the first suction port and the sewage tank, dust and sewage on the surface of the floor or carpet enter the first air duct through the first suction port in sequence and then enter the sewage tank for collection, thereby improving the suction efficiency. The handheld accessory is connected with the sewage tank through a second suction port, so that dust and sewage on the surface of the table, sofa, curtain, car interior, etc. can be sucked into the sewage tank through the second suction port for collection. By arranging a second air duct between the second suction port and the sewage tank, dust and sewage on the surface of the table, sofa, curtain, car interior, etc. enter the second air duct through the second suction port in sequence and then enter the sewage tank for collection, thereby improving the suction efficiency.

[0007] In actual use, the floor brush assembly and the handheld accessory are often used separately, so the first air duct and the second air duct need to be switched to be connected with the sewage tank, and a rotatable sealing rotating member is provided at the junction of the first air duct, the second air duct and the sewage tank, and the sealing rotating member is rotated to switch the first air duct to be connected with the sewage tank or the second air duct to be connected with the sewage tank. When the handheld accessory needs to be used, the sealing rotating member is rotated to block the first air duct, so that the second air duct is connected with the sewage tank, and dust and sewage can be collected in the sewage tank through the second suction port through the second air duct, and the air suction efficiency is high. When the floor brush assembly needs to be used, the sealing rotating member is rotated to the second air duct, so that the first air duct is connected with the sewage tank, and dust and sewage can be collected in the sewage tank through the first suction port through the first air duct, and the air suction efficiency is high.

[0008] When actually using the floor brush assembly, the user mostly pushes the body to push the floor brush assembly to move on the surface to be cleaned. In this solution, the body and the floor brush assembly are rotatably connected, so that the user can tilt the body when using the floor brush assembly. Compared with the height of the upright body, the body of this solution can be rotated according to the user's height or usage habits when pushing the floor brush assembly. The tilted body is more suitable for different users. It is more labor-saving to push the floor brush assembly with the tilted body, and the user can apply force to the tilted body more smoothly, which provides a better user experience.

[0009] By arranging a driving assembly for driving the sealing rotating member to rotate between the machine body and the floor brush assembly, when the machine body is in an upright state relative to the floor brush assembly, this is the initial state, the floor brush assembly is in an unusable state, the handheld accessory is in a usable state, the driving assembly is not subjected to force, and therefore the sealing rotating member does not rotate, the sealing rotating member blocks the first air duct, so that the second air duct is connected to the sewage tank, and the user can use the handheld accessory to clean dust and sewage on surfaces such as desktops, sofas, curtains, and car interiors. When the machine body is in a tilted state relative to the floor brush assembly, the floor brush assembly is in a usable state, the handheld accessory is in an unusable state, and the driving assembly is driven by the rotation of the machine body. The force drives the sealing rotating part to rotate, and the sealing rotating part blocks the second air duct by rotating, so that the first air duct is connected to the sewage tank. The user can use the floor brush assembly to clean the dust and sewage on the surface of the floor or carpet. The user only needs to adjust the body according to actual use needs to automatically realize the floor brush mode and accessory mode. When the floor brush assembly needs to be used for cleaning, the user will tilt the body so that the whole machine automatically switches to the floor brush mode. When the handheld accessory needs to be used for cleaning, the user does not need to tilt the body. The body is in an upright state relative to the floor brush assembly, so that the whole machine automatically switches to the accessory mode without the need for additional manual operation by the user, and the user experience is better.

The fixed gear is installed on the floor brush assembly, the first transmission gear is rotatably installed on the machine body, and the second transmission gear is installed on the sealing rotating member. One side of the first transmission gear is connected to the fixed gear, and the other side of the first transmission gear is connected to the second transmission gear. When the machine 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, so that the second transmission gear drives the sealing rotating member to rotate.

[0011] In the present technical solution, a driving assembly is provided consisting of a fixed gear, a first transmission gear and a second transmission gear, wherein the first transmission gear is mounted on the machine body and the second transmission gear is mounted on the sealing rotating member, the first transmission gear and the second transmission gear are meshed for transmission, and the first transmission gear is driven to rotate synchronously by the rotation of the machine body, the first transmission gear drives the second transmission gear to rotate by rotation, and the second rotating gear drives the sealing rotating member to rotate by rotation, so that when the machine body rotates relative to the floor brush assembly, the floor brush mode or the accessory mode can be automatically switched by the driving assembly; considering that the sealing rotating member is to just block the first air duct or the second air duct, the second transmission gear needs to stop rotating when it just rotates to the first air duct opening or the second air duct opening, and the first transmission gear is mounted on the machine body, and the rotation angle of the first transmission gear changes with the machine body, so the second transmission gear must stop transmission 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, and the fixed gear is used to enable the first transmission gear to continue to rotate according to a preset trajectory after disengaging from the second transmission gear;

[0012] When the machine body rotates and tilts relative to the floor brush assembly, the machine body drives the first transmission gear to rotate, thereby driving the second transmission gear to drive the sealing rotating member 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 sealing rotating member is connected to 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 with the body along the fixed gear. When the machine body rotates and resets relative to the floor brush assembly, the machine body drives the first transmission gear to rotate and reset. The first transmission gear rotates and resets 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 sealing rotating member to rotate to block the first air duct. The sealing rotating member is connected to the second air duct and the sewage outlet, and the handheld accessory is in a usable state. The drive assembly has a simple structure and high transmission efficiency, and the gear transmission structure is reliable and has a long service life.

The sealing rotating member is rotatably installed on the connecting seat, and the sealing rotating member switches the connection between the first interface and the third interface or the connection between the second interface and the third interface by rotation.

[0014] In the present technical solution, a connecting seat is provided in the body, and a first interface, a second interface and a third interface are provided on the connecting seat. The connecting seat is connected to the first air duct through the first interface, the connecting seat is connected to the second air duct through the second interface, and the connecting seat is connected to the sewage tank through the third interface. The first air duct, the second air duct and the sewage tank are connected through the connecting seat. The sealing rotating part can be rotatably installed in the connecting seat to switch the floor brush mode or the accessory mode. The installation structure is simple and reliable. The sealing rotating part can block the first interface or the second interface by rotating in the connecting seat, thereby blocking the first air duct or the second air duct, which is beneficial to improving the overall sealing.

[0015] As an improvement, the sealing rotatable member is fitted with a sealing ring, which is sealed to the inner wall of the connection base via the sealing ring.

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 under 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 to 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 to block the second water channel, so that the first water channel is connected to the clean water tank.

By providing the driving assembly 5 for driving the sealing rotating member 4 to rotate between the machine body 1 and the floor brush assembly 2, when the machine body 1 is in an upright state relative to the floor brush assembly 2, this is the initial state, the floor brush assembly 2 is in an unusable state, the handheld accessory 3 is in a usable state, the driving assembly 5 is not subjected to force, and therefore the sealing rotating member 4 does not rotate, the sealing rotating member 4 blocks the first air duct 22, so that the second air duct 32 is connected to the sewage tank 11, and the user can use the handheld accessory 3 to clean dust and sewage on surfaces such as desktops, sofas, curtains, and car interiors. When the machine body 1 is in a tilted state relative to the floor brush assembly 2, the floor brush assembly 2 is in a usable state, the handheld accessory 3 is in a In the unusable state, the driving component 5 is driven by the force of the rotation of the body 1 to drive the sealing rotating part 4 to rotate. The sealing rotating part 4 blocks the second air duct 32 by rotation, so that the first air duct 22 is connected to the sewage tank 11. The user can use the floor brush component 2 to clean the dust and sewage on the surface of the floor or carpet.
