Description

Technical Field

[0001] The present invention relates to the technical field of household electrical appliances, and in particular to a cleaning component and a cleaning device. Background Art

[0002] The conventional sweeping robot includes a roller brush and a motor for driving the roller brush to rise and fall. However, the motor is usually arranged in the drum of the roller brush, which increases the weight of the roller brush and makes it more difficult to rise and fall. Summary of the Invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art or related art.

[0004] To this end, a first object of the present invention is to provide a cleaning assembly.

[0005] A second object of the present invention is to provide a cleaning device.

[0006] To achieve at least one of the above-mentioned purposes, according to a first aspect of the present invention, a cleaning assembly is proposed, comprising: a main body; a roller device for cleaning the floor; a driving device, provided on the main body, the driving device being located outside the roller device, the driving device being connected to the roller device, the roller device comprising a roller brush assembly, the driving device being capable of driving the roller brush assembly to rotate relative to the main body to clean the floor; a lifting device, provided on the main body, the lifting device being located outside the roller device, the lifting device being connected to the roller device and being capable of driving the roller device to rise or fall relative to the main body.

[0007] The cleaning assembly proposed in this application is capable of cleaning the floor. The cleaning assembly includes a main body and a roller device, wherein the roller device is connected to the main body and includes a roller brush assembly. The roller brush assembly is capable of rotating relative to the main body. When the cleaning assembly is placed on the floor, when the roller brush assembly rotates relative to the main body, the roller brush assembly also rotates relative to the floor to clean the floor.

[0008] Furthermore, in order to drive the roller brush assembly in the roller device to rotate relative to the main body, the present application further provides a driving device in the cleaning assembly, the driving device being used to drive the roller brush assembly to rotate. Specifically, the driving device is provided in the main body and connected to the roller device. When the cleaning assembly is cleaning the floor, the driving device can drive the roller brush assembly to rotate relative to the main body. At this time, the roller brush assembly contacts the floor and rotates relative to the floor, thereby enabling the roller brush assembly to clean the floor.

[0009] Understandably, when there are relatively sticky stains or other stains that are not suitable for cleaning with a roller brush assembly on the ground, it is difficult for the roller brush assembly to clean the stains. If the roller brush assembly is in contact with the ground and passes over the stains, the surface of the roller brush assembly will stick to the stains and carry the stains to other locations, thereby expanding the scope of the stains. In order to avoid the above-mentioned problems and prevent the roller brush assembly from sticking to stains on the ground that are difficult to clean, the present application also provides a lifting device in the cleaning assembly. The lifting device is used to raise or lower the roller device so that the roller device can be raised and separated from the ground when passing over stains that are difficult to clean, thereby avoiding contact between the roller device and the stains. Specifically, the lifting device is provided on the main body and connected to the roller device. The lifting device can raise or lower the roller device. When the cleaning assembly passes over stains that are difficult to clean, the lifting device raises the roller device in advance and separates the roller device from the ground. In this way, the roller device can be prevented from contacting the stains, thereby preventing the roller brush assembly from carrying the stains to other locations, thereby avoiding the expansion of the stains. After the cleaning assembly passes through the stain, the lifting device lowers the roller device so that the roller device contacts the ground, and the roller device can continue to clean the ground normally.

[0010] Furthermore, the drive device and the lifting device are both located outside the drum device to reduce the weight of the drum device itself. It is understood that the heavier the drum device, the more energy the lifting device consumes when raising or lowering the drum device, and the more unstable the drum device becomes during the lifting process. In order to enable the lifting device to stably raise or lower the drum device and reduce the energy consumption of the lifting device when raising or lowering the drum device, the present application disposes the drive device and the lifting device outside the drum device to reduce the weight of the drum device, thereby improving the stability of the drum device during the lifting process.

[0011] By providing a lifting device within the cleaning assembly and connecting the lifting device to the roller assembly, the lifting device can be used to raise the roller assembly when encountering difficult-to-clean stains, preventing the roller assembly from contacting the stains. This, in turn, prevents the roller brush assembly from carrying the stains to other locations, thereby preventing the stains from spreading. By arranging the drive device and lifting device outside the roller assembly, the weight of the roller assembly can be reduced, thereby improving the stability of the roller assembly during the lifting process and reducing the energy consumption of the lifting device when raising and lowering the roller assembly.

[0012] The cleaning component according to the present invention may also have the following distinguishing technical features:

[0013] In some technical solutions, optionally, the width of the roller brush assembly is greater than or equal to the width of the main body.

[0014] In this technical solution, the relationship between the width of the roller brush assembly and the width of the main body is defined. Specifically, the width of the roller brush assembly is greater than or equal to the width of the main body. Understandably, there is an area on the floor of a house that is connected to the wall. If the width of the roller brush assembly is smaller than the width of the main body, it will cause the roller brush assembly to have difficulty cleaning the floor at the corner. In order to enable the roller brush assembly to contact the floor at the corner to clean the floor at the corner, the present application sets the width of the roller brush assembly to be greater than or equal to the width of the main body, thereby preventing the main body from contacting the wall before the roller brush assembly, preventing the roller brush assembly from being unable to approach the floor at the corner, and enabling the roller brush assembly to contact the floor at the corner to clean the floor at the corner. Among them, the width of the roller brush assembly can be greater than the width of the main body, or can be equal to the width of the main body.

[0015] In a possible technical solution, the width of the roller brush assembly is equal to the width of the main body. In this way, the roller brush assembly can contact the ground at the corner of the wall, so that the cleaning assembly can clean the ground at the corner of the wall. It can also make the appearance of the product flat and beautiful, reducing the space occupied by the product.

[0016] By setting the width of the roller brush assembly to be greater than or equal to the width of the main body, the main body can be prevented from contacting the wall before the roller brush assembly, preventing the roller brush assembly from being unable to approach the ground at the corner of the wall, so that the roller brush assembly can contact the ground at the corner of the wall to clean the ground at the corner of the wall.

[0017] In some technical solutions, optionally, the roller device also includes: a shell assembly, a roller brush assembly including at least two roller brushes, any roller brush having a first mounting cavity, and at least a portion of the shell assembly extending into any first mounting cavity; a transmission shaft assembly, connected to the driving device, the shell assembly having a second mounting cavity, a portion of the transmission shaft assembly is located in the second mounting cavity, the transmission shaft assembly extends out of the second mounting cavity and is connected to the roller brush, and the driving device drives the roller brush to rotate through the transmission shaft assembly.

[0018] This technical solution further defines the structure of the roller device. The roller device also includes a housing assembly and a drive shaft assembly. The housing assembly is used to mount and protect the roller brush assembly, and the drive shaft assembly is used to transmit torque to drive the roller brush assembly to rotate relative to the main body. Specifically, the roller brush assembly includes at least two hollow roller brushes, each of which has a first mounting cavity. At least a portion of the housing assembly extends into each first mounting cavity. In this manner, each roller brush can be mounted on the housing assembly to complete the installation of the roller brush assembly.

[0019] Furthermore, a drive shaft assembly is connected to the drive device and each roller brush. The drive assembly is capable of transmitting the torque of the drive device to the roller brushes, thereby driving the roller brushes to rotate relative to the main body. Specifically, the housing assembly has a second mounting cavity, and the drive shaft assembly is mounted in the second mounting cavity. A portion of the drive device extends into the second mounting cavity and contacts the drive shaft assembly, transmitting the torque of the drive device to the drive shaft assembly. Both ends of the drive shaft assembly extend from the second mounting cavity and connect to each roller brush. The drive shaft assembly is capable of transmitting the torque output by the drive device to each roller brush, thereby driving the roller brushes to rotate relative to the main body to clean the floor.

[0020] By setting a shell assembly in the drum device, the roller brush can be protected and installed through the shell assembly. By setting a transmission shaft assembly in the drum device, the torque output by the driving device can be transmitted to each roller brush through the transmission shaft assembly to drive the roller brush to rotate relative to the main body to clean the floor.

[0021] In some technical solutions, optionally, the driving device includes: a driving motor, which is arranged on the main body, and the driving motor has a first transmission member; a driving shaft; a second transmission member, which is connected to one end of the driving shaft, the second transmission member is adapted to the first transmission member, and the driving motor drives the driving shaft to rotate through the first transmission member and the second transmission member; a third transmission member, which is connected to the end of the driving shaft away from the second transmission member; the driving shaft assembly includes: a main shaft, which is connected to the roller brush; a fourth transmission member, which is connected to the main shaft, the fourth transmission member is adapted to the third transmission member, and the driving shaft drives the main shaft to rotate through the third transmission member and the fourth transmission member.

[0022] In this technical solution, the structure of the drive device is defined. The drive device includes a drive motor, a drive shaft, a second transmission member and a third transmission member. Among them, the drive motor is arranged on the main body, and the drive motor has a first transmission member for outputting torque. The second transmission member and the third transmission member are respectively arranged at both ends of the drive shaft, the second transmission member is adapted to the first transmission member, and the third transmission member is adapted to the drive shaft assembly. Specifically, the drive motor outputs torque to the drive shaft through the first transmission member and the second transmission member to drive the drive shaft to rotate. Since the drive shaft is connected to the third transmission member, the third transmission member cooperates with the drive shaft assembly, so that the drive shaft can transmit torque to the drive shaft assembly through the third transmission member, so that the drive shaft assembly rotates, and then the roller brush is driven to rotate through the drive shaft assembly.

[0023] Furthermore, the drive shaft assembly includes a main shaft and a fourth transmission member. The fourth connecting member is connected to the main shaft. The fourth transmission member is used to cooperate with the third transmission member. The drive shaft transmits torque to the main shaft through the third and fourth transmission members to drive the main shaft to rotate. The fourth transmission member can be connected to the center of the main shaft or to a position near the end of the main shaft. Both ends of the main shaft are connected to the roller brush, which is then driven by the main shaft to rotate, thereby realizing the drive device driving the roller brush assembly.

[0024] In a possible technical solution, the fourth transmission member is connected to the center of the main shaft, so that the forces at both ends of the main shaft can be balanced, so that the roller brushes connected to both ends of the main shaft can rotate smoothly.

[0025] By arranging a driving shaft, a first transmission member, a second transmission member and a third transmission member in the driving device, and arranging a fourth transmission member adapted to the third transmission member in the transmission shaft assembly, torque transmission can be achieved through the cooperation between the first transmission member and the second transmission member, and the cooperation between the third transmission member and the fourth transmission member, so that the torque output by the driving motor is transmitted to the roller brush through the driving shaft and the main shaft in turn, so as to realize the driving of the roller brush assembly by the driving device, so that the roller brush assembly can rotate relative to the main body.

[0026] In some technical solutions, optionally, the first transmission member, the second transmission member, the third transmission member and the fourth transmission member are bevel gears, and there is an angle between the drive shaft and the main shaft.

[0027] In this technical solution, the first transmission member, the second transmission member, the third transmission member, and the fourth transmission member are defined. Specifically, the first transmission member, the second transmission member, the third transmission member, and the fourth transmission member are bevel gears, and there is an angle between the drive shaft and the main shaft. It is understandable that the two bevel gears can change the direction of rotation when they are in conjunction with each other. Therefore, the present application can change the extension direction of the shaft used to transmit torque during the process of transmitting torque by setting the first transmission member, the second transmission member, the third transmission member, and the fourth transmission member as bevel gears. In this way, it is easy to layout the drive device and the transmission shaft assembly, making the structure of the product more compact, reducing the installation space required for the drive device and the transmission shaft assembly, and facilitating the miniaturization design of the product.

[0028] In a possible technical solution, the axis of the drive shaft is perpendicular to the axis of the main shaft.

[0029] In some technical solutions, optionally, the transmission shaft assembly further includes: a plurality of bearings, which are sleeved on the main shaft, the bearings are located in the second mounting cavity, and the bearings are used to support the main shaft.

[0030] This technical solution further defines the structure of the drive shaft assembly. The drive shaft assembly also includes multiple bearings, which are mounted on the main shaft and are capable of rotating relative to the bearings. The bearings are located within the second mounting cavity and support the main shaft, ensuring stable rotation of the main shaft and ensuring the stability of the roller brush assembly.

[0031] In one possible technical solution, the multiple bearings include two first bearings and two second bearings. The two first bearings are respectively arranged near the two ends of the main shaft, and the two second bearings are located between the two first bearings. The two first bearings are symmetrically arranged relative to the center of the main shaft, and the two second bearings are symmetrically arranged relative to the center of the main shaft. The diameter of the first bearing is larger than that of the second bearing. The first bearing includes a first bearing bracket and a first bearing portion. The first bearing portion is sleeved on the main shaft, and the main shaft can rotate relative to the first bearing portion. The first bearing bracket is sleeved on the first bearing portion, and the first bearing bracket supports the first bearing portion. The second bearing includes a second bearing bracket and a second bearing portion. The second bearing portion is sleeved on the main shaft, and the main shaft can rotate relative to the second bearing portion. The second bearing bracket is sleeved on the second bearing portion, and the second bearing bracket supports the second bearing portion.

[0032] By arranging a plurality of bearings for supporting the main shaft in the transmission shaft assembly, the main shaft can be rotated stably, thereby enabling the roller brush assembly to rotate smoothly.

[0033] In some technical solutions, optionally, the transmission shaft assembly further includes: at least two transmission members, which are used to connect the main shaft to the corresponding roller brush so that the main shaft can drive the roller brush to rotate.

[0034] This technical solution further defines the structure of the transmission shaft assembly. The transmission shaft assembly also includes at least two transmission members, which are used to connect the main shaft and corresponding roller brushes. Specifically, the number of transmission members is the same as the number of roller brushes, and each transmission member corresponds to each roller brush. The transmission member is located at the end of the main shaft and is capable of connecting the corresponding roller brush to the main shaft, so that the main shaft can drive the roller brush to rotate.

[0035] In one possible technical solution, the wall of the first mounting cavity of the roller brush has a slot adapted for the transmission member. The transmission member engages within the corresponding slot to connect the transmission member and the roller brush. A rubber vibration damping ring is provided between the transmission member and the slot wall to provide vibration damping, ensuring smoother rotation of the roller brush and reducing noise generated during rotation.

[0036] By arranging a transmission member in the transmission shaft assembly, the roller brush can be connected to the main shaft through the transmission member, so that the main shaft can drive the roller brush to rotate.

[0037] In some technical solutions, optionally, the shell assembly includes: a main shell, the main shell covers at least a portion of any roller brush, and the lifting device is connected to the main shell; a first sub-shell, connected to the main shell; a second sub-shell, detachably connected to the first sub-shell, and the first sub-shell and the second sub-shell together form a second installation cavity.

[0038] This technical solution defines the structure of the housing assembly. It includes a main housing, a first sub-housing, and a second sub-housing. The main housing covers at least a portion of each roller brush, providing both protection and position control. A lifting mechanism is connected to the main housing, driving the roller brush through the main housing to achieve lifting motion.

[0039] Furthermore, the first sub-housing is connected to the main housing, and the second sub-housing is connected to the first sub-housing. Specifically, the first sub-housing and the second sub-housing are connected by screws. When the second sub-housing is connected to the first sub-housing, the first sub-housing and the second sub-housing together form a second mounting cavity, which is used to mount a portion of the transmission shaft assembly.

[0040] By providing a main housing within the housing assembly, the roller brush can be protected to a certain extent and can also be positioned. By providing a first sub-housing and a second sub-housing within the housing assembly, a second mounting cavity for accommodating a portion of the transmission shaft assembly can be formed by the first and second sub-housings, thereby securing the transmission shaft assembly.

[0041] In some technical solutions, optionally, the cleaning component also includes: a pump body assembly, which is arranged on the main body; a liquid guide plate, which is connected to the main shell, the main shell has a liquid guide groove, the liquid guide plate and the groove wall of the liquid guide groove are combined to form a liquid guide channel, the liquid guide plate is provided with a liquid inlet pipe, the liquid inlet pipe is connected to the pump body assembly, and the liquid guide channel is connected to the liquid inlet pipe; wherein, the main shell has at least one liquid discharge port, the liquid discharge port is connected to the liquid guide channel, and the liquid discharge port faces the surface of the roller brush.

[0042] In this technical solution, the structure of the cleaning assembly is further defined. The cleaning assembly can be used in a sweeping robot and further includes a pump assembly and a liquid guide plate. The pump assembly is disposed on the main body and can be connected to the water tank of the sweeping robot and extract liquid from the water tank. The liquid guide plate is connected to the main housing, which has a liquid guide groove. The liquid guide plate and the groove wall of the liquid guide groove together form a liquid guide channel. The liquid guide plate has a liquid inlet pipe that is connected to the pump assembly. The pump assembly can pump liquid from the water tank into the liquid guide channel through the liquid inlet pipe. The liquid guide plate can be connected to the main housing by screws.

[0043] Furthermore, the main shell has at least one drain port, which is arranged on the groove wall of the liquid guide groove. The drain port is arranged toward the surface of the roller brush and is connected to the liquid guide channel. The liquid in the liquid guide channel flows to the roller brush through the drain port to wet the roller brush so that the roller brush can clean the floor.

[0044] In one possible technical solution, there are two roller brushes, two liquid guide grooves, and two liquid guide plates. The two liquid guide grooves are located on the main housing at positions corresponding to the roller brushes, and the two liquid guide plates are connected to the openings of the corresponding liquid guide grooves. The bottom wall of each liquid guide groove is provided with multiple drainage ports, which are oriented toward the corresponding roller brush. This allows liquid in the liquid guide groove to flow toward the roller brush, wetting it and allowing it to clean the floor.

[0045] By arranging a pump body assembly in the cleaning assembly, arranging a liquid guide groove on the main shell, and connecting the pump body assembly with the liquid guide channel formed by the liquid guide groove, the liquid in the water tank of the sweeping robot can be pumped into the liquid guide channel through the pump body assembly, and the liquid guide channel guides the liquid to the surface of the roller brush, wetting the surface of the roller brush, so that the roller brush can clean the floor more effectively, and the cleaning assembly has the effect of mopping the floor.

[0046] In some technical solutions, optionally, the cleaning component also includes: a scraper bar connected to the shell component, the scraper bar is in contact with the surface of the roller brush, and when the roller brush rotates, the scraper bar can remove the sewage on the surface of the roller brush; a sewage box connected to the main body, the sewage box is used to hold sewage, and the scraper bar is arranged at the opening of the sewage box.

[0047] In this technical solution, the structure of the cleaning component is further defined. The cleaning component also includes a scraper bar and a sewage box. The scraper bar is used to scrape off the sewage on the surface of the roller brush, and the sewage box is used to collect the sewage scraped off by the scraper bar. Specifically, the scraper bar is connected to the shell assembly, and the scraper bar fits tightly against the surface of the roller brush. Since the surface of the roller brush is wetted, sewage will be generated on the surface of the wet roller brush during the process of cleaning the ground. Scraping off the sewage on the surface of the roller brush by the scraper bar can avoid secondary pollution of the ground by the sewage, thereby improving the cleaning effect of the roller brush. The cleaning component is also provided with a scraper bar pressing plate, which is connected to the shell assembly. The scraper bar pressing plate is used to press the scraper bar against the surface of the roller brush to improve the decontamination ability of the scraper bar.

[0048] Furthermore, the cleaning component is also provided with a sewage box, in which the sewage scraped by the scraping bar can be collected. Specifically, the sewage box is connected to the main body, and the scraping bar is provided at the opening of the sewage box. The sewage scraped by the scraping bar can flow into the sewage box to prevent the sewage from flowing onto the ground and causing pollution.

[0049] By arranging a scraping bar on the surface of the roller brush, the sewage on the surface of the roller brush can be scraped off by the scraping bar to avoid secondary pollution of the ground by the sewage, thereby improving the cleaning effect of the roller brush.

[0050] In some technical solutions, optionally, the lifting device includes: a base, provided on the main body; a lifting motor, installed on the base; a lifting arm, rotatably connected to the base, the lifting motor is connected to the lifting arm, and the lifting arm is connected to the roller device, and the lifting motor is used to drive the lifting arm to rotate relative to the base to drive the roller device to rise or fall relative to the main body.

[0051] This technical solution defines the structure of a lifting device. The lifting device includes a base, a lifting motor, and a lifting arm. The lifting motor is used to drive the lifting arm to raise or lower the roller device. Specifically, the base is mounted on the main body, the lifting motor is mounted on the base, the lifting arm is rotatably connected to the base, the lifting motor is connected to the lifting arm, and the lifting arm is connected to the roller device. The lifting motor can drive the lifting arm to rotate relative to the base, thereby driving the roller device to be raised or lowered relative to the main body.

[0052] In one possible technical solution, the lifting arm includes multiple sub-arms connected end-to-end to form a parallelogram structure. Any two adjacent sub-arms are rotatably connected, and at least one of the multiple sub-arms is rotatably connected to the base. When the lifting motor drives the lifting arm to raise or lower the roller assembly, the two connected sub-arms rotate relative to each other, and the angle between the two connected sub-arms changes, thereby raising or lowering the roller assembly.

[0053] By arranging a lifting motor and a lifting arm in the lifting device and connecting the lifting arm to the roller device, the lifting motor can drive the lifting arm to lift or lower the roller device.

DETAILED DESCRIPTION

[0068] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, in the absence of conflict, the embodiments of the present application and the features therein can be combined with each other.

[0069] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0070] Refer to the following Figures 1 to 7 A cleaning assembly 100 and a cleaning apparatus according to some embodiments of the present invention are described.

[0071] In one embodiment according to the present application, Figure 1 As shown, the present invention proposes a cleaning component 100, including: a main body 110; a roller device 120, for cleaning the floor; a driving device 130, provided on the main body 110, the driving device 130 is located outside the roller device 120, the driving device 130 is connected to the roller device 120, the roller device 120 includes a roller brush assembly 150, the driving device 130 can drive the roller brush assembly 150 to rotate relative to the main body 110 to clean the floor; a lifting device 140, provided on the main body 110, the lifting device 140 is located outside the roller device 120, the lifting device 140 is connected to the roller device 120 and can drive the roller device 120 to rise or fall relative to the main body 110.

[0072] The cleaning assembly 100 proposed in the present application can clean the floor. The cleaning assembly 100 includes a main body 110 and a roller device 120. The roller device 120 is connected to the main body 110 and includes a roller brush assembly 150. The roller brush assembly 150 can rotate relative to the main body 110. When the cleaning assembly 100 is placed on the floor, when the roller brush assembly 150 rotates relative to the main body 110, the roller brush assembly 150 also rotates relative to the floor to clean the floor.

[0073] Furthermore, in order to drive the roller brush assembly 150 in the roller device 120 to rotate relative to the main body 110, the present application further provides a driving device 130 in the cleaning assembly 100. The driving device 130 is used to drive the roller brush assembly 150 to rotate. Specifically, the driving device 130 is provided on the main body 110 and connected to the roller device 120. When the cleaning assembly 100 cleans the floor, the driving device 130 can drive the roller brush assembly 150 to rotate relative to the main body 110. At this time, the roller brush assembly 150 contacts the floor and rotates relative to the floor, thereby enabling the roller brush assembly 150 to clean the floor.

[0074] Understandably, when there are relatively sticky stains or other stains that are not suitable for cleaning with the roller brush assembly 150 on the ground, it is difficult for the roller brush assembly 150 to clean the stains. If the roller brush assembly 150 is in contact with the ground and passes over the stains, the surface of the roller brush assembly 150 will stick to the stains and carry the stains to other locations, expanding the scope of the stains. To avoid the above problems and prevent the roller brush assembly 150 from sticking to stains on the ground that are difficult to clean, the present application also provides a lifting device 140 in the cleaning assembly 100. The lifting device 140 is used to raise or lower the roller device 120 so that the roller device 120 can be raised and separated from the ground when passing over difficult-to-clean stains, thereby preventing the roller device 120 from contacting the stains. Specifically, the lifting device 140 is provided on the main body 110 and connected to the roller device 120. The lifting device 140 can raise or lower the roller device 120. When the cleaning assembly 100 passes over a difficult-to-clean stain, the lifting device 140 raises the roller device 120 in advance, separating the roller device 120 from the ground. This prevents the roller device 120 from contacting the stain, thereby preventing the roller brush assembly 150 from carrying the stain to other locations and preventing the stain from spreading. After the cleaning assembly 100 passes over the stain, the lifting device 140 lowers the roller device 120 to contact the ground, allowing the roller device 120 to continue cleaning the ground normally.

[0075] Furthermore, the drive device 130 and the lifting device 140 are both disposed outside the drum device 120 to reduce the weight of the drum device 120. It is understood that the heavier the drum device 120, the more energy the lifting device 140 consumes when raising or lowering the drum device 120, and the more unstable the drum device 120 becomes during the raising and lowering process. To enable the lifting device 140 to stably raise or lower the drum device 120 and reduce the energy consumption of the lifting device 140 when raising or lowering the drum device 120, the present application disposes the drive device 130 and the lifting device 140 outside the drum device 120 to reduce the weight of the drum device 120, thereby improving the stability of the drum device 120 during the raising and lowering process.

[0076] By providing a lifting device 140 in the cleaning assembly 100 and connecting the lifting device 140 to the roller assembly 120, the lifting device 140 can be used to raise the roller assembly 120 when it encounters a difficult-to-clean stain, thereby preventing the roller assembly 120 from contacting the stain. This, in turn, prevents the roller brush assembly 150 from carrying the stain to other locations, thereby preventing the stain from spreading. By arranging the drive device 130 and the lifting device 140 outside the roller assembly 120, the weight of the roller assembly 120 can be reduced, thereby improving the stability of the roller assembly 120 during the lifting process and reducing the energy consumption of the lifting device 140 when raising and lowering the roller assembly 120.

[0077] In some embodiments, optionally, the width of the roller brush assembly 150 is greater than or equal to the width of the main body 110 .

[0078] In this embodiment, the relationship between the width of the roller brush assembly 150 and the width of the main body 110 is defined. Specifically, the width of the roller brush assembly 150 is greater than or equal to the width of the main body 110. It is understandable that there is an area on the floor of a house that is connected to the wall. If the width of the roller brush assembly 150 is smaller than the width of the main body 110, it will make it difficult for the roller brush assembly 150 to clean the floor in the corner. In order to enable the roller brush assembly 150 to contact the floor in the corner to clean the floor in the corner, the present application sets the width of the roller brush assembly 150 to be greater than or equal to the width of the main body 110, thereby preventing the main body 110 from contacting the wall before the roller brush assembly 150, preventing the roller brush assembly 150 from being unable to approach the floor in the corner, and allowing the roller brush assembly 150 to contact the floor in the corner to clean the floor in the corner. The width of the roller brush assembly 150 can be greater than the width of the main body 110 or equal to the width of the main body 110.

[0079] In a possible embodiment, the width of the roller brush assembly 150 is equal to the width of the main body 110. In this way, the roller brush assembly 150 can contact the ground at the corner of the wall, allowing the cleaning assembly 100 to clean the ground at the corner of the wall, and the appearance of the product can be flat and beautiful, reducing the space occupied by the product.

[0080] By setting the width of the roller brush assembly 150 to be greater than or equal to the width of the main body 110, it is possible to avoid the main body 110 contacting the wall before the roller brush assembly 150, preventing the roller brush assembly 150 from being unable to approach the ground at the corner of the wall, so that the roller brush assembly 150 can contact the ground at the corner of the wall to clean the ground at the corner of the wall.

[0081] In some embodiments, optionally, as Figure 2 and Figure 5 As shown, the roller device 120 also includes: a shell assembly 160, a roller brush assembly 150 including at least two roller brushes 151, any roller brush 151 has a first mounting cavity 152, and at least a portion of the shell assembly 160 extends into any first mounting cavity 152; a transmission shaft assembly 170, connected to the driving device 130, the shell assembly 160 has a second mounting cavity 164, a portion of the transmission shaft assembly 170 is located in the second mounting cavity 164, the transmission shaft assembly 170 extends out of the second mounting cavity 164 and is connected to the roller brush 151, and the driving device 130 drives the roller brush 151 to rotate through the transmission shaft assembly 170.

[0082] In this embodiment, the structure of the roller device 120 is further defined. The roller device 120 also includes a housing assembly 160 and a drive shaft assembly 170. The housing assembly 160 is used to mount and protect the roller brush assembly 150, while the drive shaft assembly 170 is used to transmit torque to drive the roller brush assembly 150 to rotate relative to the main body 110. Specifically, the roller brush assembly 150 includes at least two hollow roller brushes 151. Each roller brush 151 has a first mounting cavity 152, and at least a portion of the housing assembly 160 extends into each first mounting cavity 152. Thus, each roller brush 151 can be mounted on the housing assembly 160 to install the roller brush assembly 150.

[0083] Furthermore, a transmission shaft assembly 170 is connected to the drive device 130 and each roller brush 151. The transmission assembly is capable of transmitting the torque of the drive device 130 to the roller brush 151, thereby driving the roller brush 151 to rotate relative to the main body 110. Specifically, the housing assembly 160 has a second mounting cavity 164, and the transmission shaft assembly 170 is mounted in the second mounting cavity 164. A portion of the drive device 130 extends into the second mounting cavity 164 and contacts the transmission shaft assembly 170, transmitting the torque of the drive device 130 to the transmission shaft assembly 170. Both ends of the transmission shaft assembly 170 extend from the second mounting cavity 164 and are connected to each roller brush 151. The transmission shaft assembly 170 is capable of transmitting the torque output by the drive device 130 to each roller brush 151, thereby driving the roller brush 151 to rotate relative to the main body 110 to clean the floor.

[0084] By setting a shell assembly 160 in the roller device 120, the roller brush 151 can be protected and installed through the shell assembly 160. By setting a transmission shaft assembly 170 in the roller device 120, the torque output by the driving device 130 can be transmitted to each roller brush 151 through the transmission shaft assembly 170 to drive the roller brush 151 to rotate relative to the main body 110 to clean the floor.

[0085] In some embodiments, optionally, as Figure 1 、 Figure 2 and Figure 5As shown, the driving device 130 includes: a driving motor 131, which is arranged on the main body 110, and the driving motor 131 has a first transmission member 132; a driving shaft 133; a second transmission member 134, which is connected to one end of the driving shaft 133, and the second transmission member 134 is adapted to the first transmission member 132, and the driving motor 131 drives the driving shaft 133 to rotate through the first transmission member 132 and the second transmission member 134; a third transmission member 135, which is connected to the end of the driving shaft 133 away from the second transmission member 134; the transmission shaft assembly 170 includes: a main shaft 171, which is connected to the roller brush 151; a fourth transmission member 172, which is connected to the main shaft 171, and the fourth transmission member 172 is adapted to the third transmission member 135, and the driving shaft 133 drives the main shaft 171 to rotate through the third transmission member 135 and the fourth transmission member 172.

[0086] In this embodiment, the structure of the drive device 130 is defined. The drive device 130 includes a drive motor 131, a drive shaft 133, a second transmission member 134, and a third transmission member 135. The drive motor 131 is disposed on the main body 110 and has a first transmission member 132 for outputting torque. The second transmission member 134 and the third transmission member 135 are respectively disposed at both ends of the drive shaft 133. The second transmission member 134 is adapted to the first transmission member 132, and the third transmission member 135 is adapted to the drive shaft assembly 170. Specifically, the drive motor 131 outputs torque to the drive shaft 133 through the first transmission member 132 and the second transmission member 134, thereby driving the drive shaft 133 to rotate. Since the drive shaft 133 is connected to the third transmission member 135, and the third transmission member 135 cooperates with the transmission shaft assembly 170, the drive shaft 133 can transmit the torque to the transmission shaft assembly 170 through the third transmission member 135, so that the transmission shaft assembly 170 rotates, and then drives the roller brush 151 to rotate through the transmission shaft assembly 170.

[0087] Furthermore, the transmission shaft assembly 170 includes a main shaft 171 and a fourth transmission member 172. The fourth connecting member is connected to the main shaft 171. The fourth transmission member 172 is used to cooperate with the third transmission member 135. The drive shaft 133 transmits torque to the main shaft 171 through the third transmission member 135 and the fourth transmission member 172 to drive the main shaft 171 to rotate. The fourth transmission member 172 can be connected to the center of the main shaft 171 or to a position near the end of the main shaft 171. Both ends of the main shaft 171 are connected to the roller brush 151, and the roller brush 151 is then driven to rotate by the main shaft 171, thereby realizing that the driving device 130 drives the roller brush assembly 150.

[0088] In a possible embodiment, the fourth transmission member 172 is connected to the center of the main shaft 171. In this way, the forces at both ends of the main shaft 171 can be balanced, so that the roller brushes 151 connected to both ends of the main shaft 171 can rotate smoothly.

[0089] By arranging a drive shaft 133, a first transmission member 132, a second transmission member 134 and a third transmission member 135 in the drive device 130, and arranging a fourth transmission member 172 adapted to the third transmission member 135 in the drive shaft assembly 170, the torque can be transmitted through the cooperation between the first transmission member 132 and the second transmission member 134, and the cooperation between the third transmission member 135 and the fourth transmission member 172, so that the torque output by the drive motor 131 is transmitted to the roller brush 151 in turn through the drive shaft 133 and the main shaft 171, so as to realize the driving of the roller brush assembly 150 by the drive device 130, so that the roller brush assembly 150 can rotate relative to the main body 110.

[0090] In some embodiments, optionally, as Figure 1 、 Figure 2 and Figure 5 As shown, the first transmission member 132 , the second transmission member 134 , the third transmission member 135 and the fourth transmission member 172 are bevel gears, and an angle is formed between the drive shaft 133 and the main shaft 171 .

[0091] In this embodiment, the first transmission member 132, the second transmission member 134, the third transmission member 135, and the fourth transmission member 172 are defined. Specifically, the first transmission member 132, the second transmission member 134, the third transmission member 135, and the fourth transmission member 172 are bevel gears, and an angle is formed between the drive shaft 133 and the main shaft 171. It can be understood that the two bevel gears can change the direction of rotation when they are in conjunction with each other. Therefore, the present application configures the first transmission member 132, the second transmission member 134, the third transmission member 135, and the fourth transmission member 172 as bevel gears, so that the extension direction of the shaft used to transmit torque can be changed during the process of transmitting torque. In this way, the layout of the drive device 130 and the transmission shaft assembly 170 can be facilitated, making the product structure more compact, reducing the installation space required for the drive device 130 and the transmission shaft assembly 170, and facilitating the miniaturization of the product.

[0092] In a possible embodiment, the axis of the driving shaft 133 is perpendicular to the axis of the main shaft 171 .

[0093] In some embodiments, optionally, as Figure 5 As shown, the transmission shaft assembly 170 further includes: a plurality of bearings, which are sleeved on the main shaft 171 , and the bearings are located in the second mounting cavity 164 , and the bearings are used to support the main shaft 171 .

[0094] In this embodiment, the structure of the transmission shaft assembly 170 is further defined. The transmission shaft assembly 170 also includes multiple bearings, which are mounted on a main shaft 171. The main shaft 171 is rotatable relative to the bearings. The bearings are located within the second mounting cavity 164 and support the main shaft 171, ensuring stable rotation of the main shaft 171 and ensuring the stability of the rotation of the roller brush assembly 150.

[0095] In one possible embodiment, the multiple bearings include two first bearings 173 and two second bearings 176. The two first bearings 173 are located near the ends of the main shaft 171, respectively, and the two second bearings 176 are located between the two first bearings 173. The two first bearings 173 and the two second bearings 176 are symmetrically arranged with respect to the center of the main shaft 171. The diameter of the first bearing 173 is larger than that of the second bearing 176. The first bearing 173 includes a first bearing bracket 174 and a first bearing portion 175. The first bearing portion 175 is mounted on the main shaft 171, and the main shaft 171 is rotatable relative to the first bearing portion 175. The first bearing bracket 174 is mounted on the first bearing portion 175, and supports the first bearing portion 175. The second bearing 176 includes a second bearing bracket 177 and a second bearing portion 178. The second bearing portion 178 is mounted on the main shaft 171, and the main shaft 171 is rotatable relative to the second bearing portion 178. The second bearing bracket 177 is sleeved on the second bearing portion 178 , and the second bearing bracket 177 supports the second bearing portion 178 .

[0096] By providing a plurality of bearings for supporting the main shaft 171 in the transmission shaft assembly 170 , the main shaft 171 can be rotated stably, thereby enabling the roller brush assembly 150 to rotate smoothly.

[0097] In some embodiments, optionally, as Figure 5 As shown, the transmission shaft assembly 170 further includes: at least two transmission members 179, and the transmission members 179 are used to connect the main shaft 171 to the corresponding roller brush 151, so that the main shaft 171 can drive the roller brush 151 to rotate.

[0098] In this embodiment, the structure of the transmission shaft assembly 170 is further defined. The transmission shaft assembly 170 also includes at least two transmission members 179, which are used to connect the main shaft 171 and the corresponding roller brushes 151. Specifically, the number of transmission members 179 is the same as the number of roller brushes 151, and each transmission member 179 corresponds to each roller brush 151. The transmission members 179 are located at the ends of the main shaft 171 and are capable of connecting the corresponding roller brush 151 to the main shaft 171, thereby enabling the main shaft 171 to drive the roller brushes 151 to rotate.

[0099] In one possible embodiment, a slot is formed on the wall of the first mounting cavity 152 of the roller brush 151 to match the transmission member 179. The transmission member 179 is engaged in the corresponding slot to connect the transmission member 179 to the roller brush 151. A rubber vibration-damping ring 193 is provided between the transmission member 179 and the slot wall to reduce vibration, allowing the roller brush 151 to rotate more smoothly and reducing noise generated during rotation.

[0100] By providing a transmission member 179 in the transmission shaft assembly 170 , the roller brush 151 can be connected to the main shaft 171 via the transmission member 179 , so that the main shaft 171 can drive the roller brush 151 to rotate.

[0101] In some embodiments, optionally, as Figure 2 、 Figure 3 and Figure 5 As shown, the shell assembly 160 includes: a main shell 161, the main shell 161 covers at least a portion of any roller brush 151, and the lifting device 140 is connected to the main shell 161; a first sub-shell 162, connected to the main shell 161; a second sub-shell 163, detachably connected to the first sub-shell 162, and the first sub-shell 162 and the second sub-shell 163 together form a second installation cavity 164.

[0102] In this embodiment, the structure of the housing assembly 160 is defined. The housing assembly 160 comprises a main housing 161, a first sub-housing 162, and a second sub-housing 163. The main housing 161 covers at least a portion of each roller brush 151, providing both protection and position control. The lifting mechanism 140 is connected to the main housing 161, driving the roller brush 151 through the main housing 161 to move upward and downward.

[0103] Furthermore, the first sub-housing 162 is connected to the main housing 161, and the second sub-housing 163 is connected to the first sub-housing 162. Specifically, the first sub-housing 162 and the second sub-housing 163 are connected by screws. When the second sub-housing 163 is connected to the first sub-housing 162, the first sub-housing 162 and the second sub-housing 163 together form a second mounting cavity 164, which is used to mount a portion of the transmission shaft assembly 170.

[0104] By providing a main housing 161 within the housing assembly 160, the roller brush 151 can be protected to a certain extent and can also be positioned to limit the roller brush 151. By providing a first sub-housing 162 and a second sub-housing 163 within the housing assembly 160, the first sub-housing 162 and the second sub-housing 163 can be combined to form a second mounting cavity 164 for accommodating a portion of the transmission shaft assembly 170, thereby allowing the transmission shaft assembly 170 to be installed and secured.

[0105] In some embodiments, optionally, as Figure 1 、 Figure 4 、 Figure 6 and Figure 7 As shown, the cleaning assembly 100 also includes: a pump body assembly 180, which is arranged on the main body 110; a liquid guide plate 165, which is connected to the main shell 161, and the main shell 161 has a liquid guide groove 166, and the liquid guide plate 165 and the groove wall of the liquid guide groove 166 are combined to form a liquid guide channel, and the liquid guide plate 165 is provided with a liquid inlet pipe 167, the liquid inlet pipe 167 is connected to the pump body assembly 180, and the liquid guide channel is connected to the liquid inlet pipe 167; wherein, the main shell 161 has at least one liquid discharge port 168, the liquid discharge port 168 is connected to the liquid guide channel, and the liquid discharge port 168 faces the surface of the roller brush 151.

[0106] In this embodiment, the structure of the cleaning assembly 100 is further defined. The cleaning assembly 100 can be used in a sweeping robot. The cleaning assembly 100 also includes a pump body assembly 180 and a liquid guide plate 165, wherein the pump body assembly 180 is provided on the main body 110, and the pump body assembly 180 can be connected to the water tank of the sweeping robot and extract the liquid in the water tank. The liquid guide plate 165 is connected to the main housing 161, and the main housing 161 has a liquid guide groove 166. The liquid guide plate 165 and the groove wall of the liquid guide groove 166 together form a liquid guide channel. The liquid guide plate 165 has a liquid inlet pipe 167, and the liquid inlet pipe 167 is connected to the pump body assembly 180. The pump body assembly 180 can pump the liquid in the water tank into the liquid guide channel through the liquid inlet pipe 167. The liquid guide plate 165 can be connected to the main housing 161 by screws.

[0107] Furthermore, if Figure 7 As shown, the main shell 161 has at least one drain port 168, which is arranged on the groove wall of the liquid guide groove 166. The drain port 168 is arranged toward the surface of the roller brush 151 and is connected to the liquid guide channel. The liquid in the liquid guide channel flows to the roller brush 151 through the drain port 168 to wet the roller brush 151 so that the roller brush 151 can clean the floor.

[0108] In one possible embodiment, there are two roller brushes 151, two liquid guide grooves 166, and two liquid guide plates 165. The two liquid guide grooves 166 are provided on the main housing 161 at positions corresponding to the roller brushes 151, and the two liquid guide plates 165 are connected to the openings of the corresponding liquid guide grooves 166. The bottom wall of each liquid guide groove 166 is provided with multiple drainage ports 168, which face the corresponding roller brush 151. The drainage ports 168 allow the liquid in the liquid guide groove 166 to flow toward the roller brush 151, wetting the roller brush 151 so that the roller brush 151 can clean the floor.

[0109] By setting a pump body assembly 180 in the cleaning assembly 100, setting a liquid guide groove 166 on the main shell 161, and connecting the pump body assembly 180 with the liquid guide channel formed by the liquid guide groove 166, the liquid in the water tank of the sweeping robot can be pumped into the liquid guide channel through the pump body assembly 180, and the liquid guide channel guides the liquid to the surface of the roller brush 151, wetting the surface of the roller brush 151, so that the roller brush 151 can clean the floor more effectively, and the cleaning assembly 100 has the effect of mopping the floor.

[0110] In some embodiments, optionally, as Figure 2 As shown, the cleaning component 100 also includes: a scraper bar 190, which is connected to the shell component 160, and the scraper bar 190 is in contact with the surface of the roller brush 151. When the roller brush 151 rotates, the scraper bar 190 can remove the sewage on the surface of the roller brush 151; a sewage box 192, which is connected to the main body 110, and the sewage box 192 is used to accommodate sewage, and the scraper bar 190 is arranged at the opening of the sewage box 192.

[0111] In this embodiment, the structure of the cleaning assembly 100 is further defined. The cleaning assembly 100 also includes a scraper bar 190 and a sewage box 192. The scraper bar 190 is used to scrape sewage off the surface of the roller brush 151, and the sewage box 192 is used to collect the sewage scraped off by the scraper bar 190. Specifically, the scraper bar 190 is connected to the housing assembly 160 and is in close contact with the surface of the roller brush 151. Because the surface of the roller brush 151 is wet, sewage is generated on the surface of the wet roller brush 151 during the floor cleaning process. Scraping the sewage off the surface of the roller brush 151 by the scraper bar 190 can prevent secondary contamination of the floor by the sewage and improve the cleaning effect of the roller brush 151. The cleaning assembly 100 also includes a scraper bar pressing plate 191, which is connected to the housing assembly 160 and is used to press the scraper bar 190 against the surface of the roller brush 151 to improve the decontamination ability of the scraper bar 190.

[0112] Further, if Figure 1As shown, the cleaning assembly 100 is further provided with a sewage box 192, and the sewage scraped by the scraping bar 190 can be collected in the sewage box 192. Specifically, the sewage box 192 is connected to the main body 110, and the scraping bar 190 is provided at the opening of the sewage box 192. The sewage scraped by the scraping bar 190 can flow into the sewage box 192 to prevent the sewage from flowing onto the ground and causing pollution to the ground.

[0113] By arranging a scraping bar 190 on the surface of the roller brush 151 , the scraping bar 190 can scrape away the sewage on the surface of the roller brush 151 , thereby preventing the sewage from causing secondary pollution to the ground and improving the cleaning effect of the roller brush 151 .

[0114] In some embodiments, optionally, as Figure 1 As shown, the lifting device 140 includes: a base 141, which is provided on the main body 110; a lifting motor 142, which is installed on the base 141; a lifting arm 143, which is rotatably connected to the base 141, the lifting motor 142 is connected to the lifting arm 143, and the lifting arm 143 is connected to the roller device 120. The lifting motor 142 is used to drive the lifting arm 143 to rotate relative to the base 141, so as to drive the roller device 120 to rise or fall relative to the main body 110.

[0115] In this embodiment, the structure of the lifting device 140 is defined. The lifting device 140 includes a base 141, a lifting motor 142, and a lifting arm 143. The lifting motor 142 is used to drive the lifting arm 143 to raise or lower the roller device 120. Specifically, the base 141 is disposed on the main body 110, the lifting motor 142 is mounted on the base 141, and the lifting arm 143 is rotatably connected to the base 141. The lifting motor 142 is connected to the lifting arm 143, and the lifting arm 143 is connected to the roller device 120. The lifting motor 142 can drive the lifting arm 143 to rotate relative to the base 141, thereby driving the roller device 120 to be raised or lowered relative to the main body 110.

[0116] In one possible embodiment, the lifting arm 143 includes a plurality of sub-arms 144, which are connected end to end to form a parallelogram structure. Any two adjacent sub-arms 144 are rotatably connected, and at least one of the plurality of sub-arms 144 is rotatably connected to the base 141. When the lifting motor 142 drives the lifting arm 143 to raise or lower the roller device 120, the two connected sub-arms 144 rotate relative to each other, and the angle between the two connected sub-arms 144 changes, thereby raising or lowering the roller device 120.

[0117] By providing a lifting motor 142 and a lifting arm 143 in the lifting device 140 and connecting the lifting arm 143 to the roller device 120 , the lifting motor 142 can drive the lifting arm 143 to lift or lower the roller device 120 .

[0118] The second aspect of the present invention further provides a cleaning device, comprising the cleaning component 100 provided in the first aspect of the present invention.

[0119] The cleaning device provided in the second aspect of the present invention includes the cleaning assembly 100 proposed in the first aspect of the present invention, and thus has all the beneficial effects of the cleaning assembly 100.

[0120] Cleaning equipment includes robot vacuums or handheld vacuums.

[0121] In one possible embodiment, Figure 1 As shown, the roller brush module (i.e., roller device 120) is installed at the tail end of the robot (i.e., cleaning equipment), and the roller brush assembly 150 in the roller brush module is as wide as the main body 110 of the robot, so that the roller brush module can clean corners.

[0122] like Figure 1 As shown, the roller brush drive motor (i.e., the drive device 130) is installed outside the roller brush module, and power is transmitted to the stepped shaft (i.e., the main shaft 171) of the roller brush 151 by the transmission shaft (i.e., the transmission shaft assembly 170), thereby reducing the weight of the roller brush module, making it easier to lift the roller brush module, and reducing the load on the lifting motor 142. In addition, compared to a roller brush module with a built-in motor, the present application sets the drive motor 131 outside the roller brush module, so that the diameter of the roller brush module is not limited by the drive motor 131, and the diameter of the roller brush assembly 150 in the roller brush module can be made smaller.

[0123] like Figure 1 As shown, the lifting module (i.e., the lifting device 140) is composed of a stepper motor (i.e., the lifting motor 142) and a parallelogram support structure (i.e., the lifting arm 143). The stepper motor controls the rotation to drive the parallelogram support rod (i.e., the lifting arm 143) to rotate to realize the lifting and lowering of the roller brush module.

[0124] like Figure 1 and Figure 2 As shown, the roller brush drive motor transmits power to the stepped shaft of roller brush 151. During this power transmission process, a pair of bevel gears (i.e., third transmission member 135 and fourth transmission member 172) redirects the power, transferring it to the stepped shaft of roller brush 151. The stepped shaft of roller brush 151 is connected to roller brush 151, transmitting power to it. Furthermore, the stepped shaft includes a bearing and a bearing support structure (i.e., first bearing 173 and second bearing 176) that supports roller brush 151. This ensures that power is transmitted to roller brush 151, causing it to rotate and clean the floor.
