Technical Field

[0002] The present application relates to the technical field of cleaning equipment, and in particular to a cleaning mechanism and a cleaning equipment. Background Art

[0003] In the related art, the drum of the cleaning equipment may encounter scenes such as carpets that are not suitable for cleaning with water during the cleaning process. At this time, there is a risk of the drum wetting the carpet, resulting in a technical defect in which the applicable scenes of the cleaning equipment are limited, causing inconvenience to users. Summary of the Invention

[0004] A first aspect of the present application provides a cleaning mechanism.

[0005] A second aspect of the present application provides a cleaning device.

[0006] In view of this, the first aspect of the present application provides a cleaning mechanism, which is used for cleaning equipment. The cleaning equipment includes a body, and the cleaning mechanism includes: a frame; a cleaning component connected to the frame; a first motor arranged in the frame and connected to the frame; a transmission component, the first end of the transmission component is connected to the first motor, and the second end of the transmission component is used to connect to the body, and the first motor drives the frame to move relative to the body through the transmission component.

[0007] In this technical solution, a cleaning mechanism is defined, which is applied to a cleaning device. The cleaning device cleans areas such as the floor, tabletop, and furniture surface through the cleaning mechanism.

[0008] Specifically, the cleaning mechanism includes a frame and a cleaning assembly. The frame positions, supports, and protects the other components of the cleaning mechanism. The cleaning assembly is connected to the frame and can clean a designated area through rotational and reciprocating motions, such as wiping the floor with a rotating roller brush.

[0009] Among them, the cleaning component maintains contact with the designated area below during the cleaning operation, and the cleaning component usually carries waste water for wiping dust. If the cleaning equipment drives the cleaning component to move to areas such as carpets that are not suitable for cleaning with wet cleaning components, the wet cleaning component may drag down the hair on the carpet, or the waste water carried by the cleaning component may contaminate the carpet, causing the dust in the carpet to adhere to the carpet hair under the action of the waste water.

[0010] In this regard, the cleaning mechanism defined in the present application also includes a first motor and a transmission assembly. The first motor is connected to the frame, the first end of the transmission assembly is connected to the power output end of the first motor, and the second end of the transmission assembly is connected to the body of the cleaning device. After the first motor is turned on, the first motor drives the transmission assembly to move, thereby driving the frame and the first motor and the cleaning assembly on the frame to move relative to the body through the moving transmission assembly. Specifically, the cleaning assembly can be driven to rise and fall relative to the designated area by the first motor and the transmission assembly, so that when encountering scenes such as carpets that are not suitable for cleaning with the cleaning assembly, the designated area can be avoided by driving the cleaning assembly to rise. When the cleaning device moves back to an area suitable for wiping by the cleaning assembly, the cleaning assembly is lowered so that the cleaning assembly contacts the designated area again to resume the cleaning operation.

[0011] It can be seen that by setting the first motor and the transmission assembly, the cleaning mechanism has a lifting function, thereby solving the technical defects of the related technology such as limited application scenarios, easy contamination of carpets, and inconvenience to users through the lifting function, thereby optimizing the structure of the cleaning mechanism, improving the practicality and reliability of the cleaning mechanism, broadening the application scenarios of the cleaning equipment, and improving the user experience.

[0012] On this basis, the first motor is integrated within the frame, and the first motor rises and falls synchronously with the frame. By placing the first motor within the frame, on the one hand, a modular and concealed design of the motor and cleaning components can be achieved, allowing the cleaning mechanism to achieve its lifting function without relying on the drive structure on the cleaning equipment. On the other hand, the first motor rationally utilizes the space inside the frame and does not encroach on the space outside the frame, thereby eliminating the need for reserving motor installation positions and motor avoidance positions on the cleaning equipment. This further achieves the technical effect of improving the structural compactness of the cleaning mechanism and cleaning equipment, providing convenient conditions for the miniaturization of the cleaning equipment.

[0013] Specifically, the transmission component can realize the lifting function through structures such as connecting rods, gears, racks, screws, reels, and wiring harnesses. This technical solution does not impose rigid restrictions on the specific structural form of the transmission component, and it is sufficient to meet the lifting transmission requirements.

[0014] In addition, the cleaning mechanism provided in this application may also have the following additional technical features:

[0015] In some technical solutions of the present application, optionally, the frame includes: a first bracket; a second bracket connected to the first bracket, the second bracket includes a mounting groove, the first motor is arranged in the mounting groove, and the cleaning component is connected to the first bracket and / or the second bracket; wherein the cleaning component and the second bracket are located below the first bracket.

[0016] In this technical solution, the frame includes a first bracket and a second bracket.

[0017] Among them, the cleaning component is fixed under the first bracket, the first bracket is plate-shaped, and the plate-shaped first bracket covers the upper area of ​​the cleaning component. The first bracket can play a shielding and protective role above the cleaning component, which can prevent the cleaning component from throwing waste water upward during the cleaning operation, thereby improving the practicality of the cleaning mechanism.

[0018] The second bracket is connected to the first bracket and is also arranged below the first bracket. The first bracket also provides shielding and protection for the second bracket, reducing the possibility of damage or failure of the first motor. Furthermore, the second bracket and the cleaning assembly are arranged side by side below the first bracket to rationally utilize the space below the first bracket and improve the compactness of the cleaning mechanism.

[0019] Specifically, the second bracket is provided with a mounting slot whose shape matches the outer contour of the first motor. During assembly, the first motor is first inserted into the mounting slot, and then the second bracket and the first motor are connected via screws. The second bracket provides positioning and protection outside the first motor, ensuring that the first motor is positioned in the predetermined working position while also reducing the possibility of the first motor being corroded by external wastewater, thereby achieving the technical effect of improving the positioning accuracy of the first motor and enhancing the structural stability and reliability of the cleaning mechanism.

[0020] In some technical solutions of the present application, optionally, the cleaning component covers the mounting slot; the second bracket further includes a through hole, and the transmission component is passed through the through hole.

[0021] In this technical solution, the cleaning assembly faces the opening of the mounting slot. After assembly, the cleaning assembly covers the opening of the mounting slot, providing a position limit for the first motor in the mounting slot, preventing the first motor from being misaligned or even falling out of the mounting slot. During assembly, the first motor must first be installed in the mounting slot, and then the cleaning assembly is fixed to the opening of the mounting slot. This allows for the rational use of the cleaning assembly and achieves the technical effect of improving the structural compactness of the cleaning mechanism.

[0022] On this basis, a through hole is provided on the second bracket, which connects the mounting slot and the external space of the second bracket. The first end of the transmission assembly is connected to the first motor in the mounting slot through the through hole to ensure that power can be transmitted to the outside of the second bracket through the transmission assembly while hiding the first motor.

[0023] In some technical solutions of the present application, optionally, the cleaning assembly includes: a first cleaning assembly connected to the second bracket; a second cleaning assembly connected to the second bracket, and the second bracket is located between the first cleaning assembly and the second cleaning assembly.

[0024] In this technical solution, the cleaning component includes a first cleaning component and a second cleaning component, which are symmetrically distributed on the left and right sides of the first motor. The first cleaning component is connected to the first end of the opening of the mounting groove on the second bracket, and the second cleaning component is connected to the second end of the opening facing away from the mounting groove.

[0025] By clamping the second bracket and the first motor between the first and second cleaning assemblies, both ends of the cleaning mechanism can be cleaned, preventing the built-in first motor from creating blind spots within the cleaning mechanism and enabling the cleaning mechanism to effectively clean corners, crevices, and other areas. Furthermore, the symmetrical distribution of the first and second cleaning assemblies on the left and right sides of the first motor balances the weight of the transmission assembly, preventing the cleaning mechanism from tilting or even tipping during lifting, thereby achieving the technical effect of enhancing the structural stability of the cleaning mechanism and smoothing its lifting and lowering.

[0026] In some technical solutions of the present application, optionally, the cleaning component includes: a shell, connected to the second bracket; a second motor, arranged in the shell; a transmission component, connected to the second motor; a roller brush, sleeved outside the shell and connected to the transmission component, and the second motor drives the roller brush to rotate relative to the shell through the transmission component.

[0027] In this technical solution, the cleaning assembly includes a shell, a second motor, a transmission component and a roller brush.

[0028] The housing is connected to the second bracket, and a cavity is formed in the housing. The second motor is disposed in the cavity, and the power output of the second motor is connected to a transmission component, which is located outside the housing. The housing is cylindrical, and the roller brush is mounted outside the housing. The housing can provide protection for the internal second motor and also provide support and positioning for the outer roller brush.

[0029] At the same time, the transmission component is connected to the roller brush, and the second motor can drive the roller brush to rotate relative to the shell through the transmission component, so that the rotating roller brush wipes the stains and dust in the designated area, thereby realizing the cleaning function of the cleaning mechanism.

[0030] During assembly, the transmission component and the roller brush are connected by simply inserting the roller brush into a predetermined position on the outside of the housing. Specifically, the connection can be achieved through an interference fit, or through snap-fit ​​structures such as ribs or grooves, with no rigid restrictions. Thus, the roller brush can be easily assembled and disassembled with a simple plug-in and pull-out action, providing convenient conditions for cleaning or replacing the roller brush, thereby achieving the technical effect of optimizing the cleaning component structure and improving the user experience.

[0031] In some technical solutions of the present application, optionally, the cleaning assembly further includes: a bearing, which is provided in the housing and located between the housing and the roller brush; wherein the outer ring of the bearing is interference fit with the roller brush.

[0032] In this technical solution, the cleaning component also includes a bearing, which is arranged between the shell and the roller brush. Specifically, the bearing is first sleeved on the outside of the shell. In the process of sleeved the roller brush on the outside of the shell, the roller brush is also sleeved on the outside of the bearing. The outer ring of the bearing and the inner ring surface of the roller brush are connected by an interference fit. In the process of the second motor driving the roller brush to rotate through the transmission component, the outer ring of the bearing rotates along with the roller brush relative to the inner ring of the bearing.

[0033] It can be seen from this that by setting up bearings, on the one hand, the bearings can provide support for the roller brush and reduce the possibility of the roller brush rotating skewedly. On the other hand, the bearings can reduce the rotational resistance of the roller brush to increase the rotation speed of the roller brush and improve the energy efficiency ratio of the second motor.

[0034] In some technical solutions of the present application, optionally, there are multiple bearings, and the multiple bearings are spaced apart in the axial direction of the housing.

[0035] In this technical solution, each cleaning assembly includes a plurality of bearings, and the plurality of bearings are sleeved on the outside of the shell, and the plurality of bearings are spaced apart in the axial direction of the shell.

[0036] By arranging multiple bearings at intervals on the outside of the shell, multiple bearings can jointly support the roller brush to ensure the smooth rotation of the roller brush, avoid skewed rotation or violent shaking of the roller brush, and thereby achieve the technical effect of improving the structural stability of the cleaning mechanism.

[0037] Specifically, the bearing includes a first bearing and a second bearing, the first bearing is fixed at the rear end of the shell, and the second bearing is fixed at the front end of the shell to support the roller brush sleeved on the outside of the shell at the front and rear sides of the shell.

[0038] In some technical solutions of the present application, optionally, the roller brush includes: a roller, which is mounted outside the shell, and the shell can be inserted into the roller from the first end of the roller, and the transmission component is connected to the inner ring surface of the roller; bristles are arranged on the outer ring surface of the roller; and an end cover is connected to the roller and covers the second end of the roller.

[0039] In this technical solution, the roller brush includes a roller, bristles and an end cover.

[0040] The drum is hollow and cylindrical, fitting over the outer shell through an opening at its first end. An end cap is connected to the second end of the drum, covering the opening at the second end to shield and protect the second motor and transmission components inside the drum, reducing the risk of motor failure. The end cap and drum are detachably connected, making it easier for users to clean and maintain the internal structure of the drum.

[0041] On this basis, the outer side of the drum is covered with bristles, which rotate synchronously during the rotation. When the bristles contact the designated area, they carry away the stains and dust attached to the designated area through friction, thus achieving a cleaning effect. In addition, the densely distributed bristles can also store a certain amount of water. During the cleaning process, the water carried by the bristles softens the stains and absorbs the dust, thereby improving the cleaning effect of the cleaning mechanism.

[0042] In some technical solutions of the present application, optionally, the transmission component is engaged with the inner ring surface of the drum, or the transmission component is interference fit with the inner ring surface of the drum.

[0043] In this technical solution, the transmission component and the roller are connected by interference fit or snap fit.

[0044] Specifically, the transmission component is provided with a boss on its circumference, and the inner surface of the roller is provided with a slot that matches the boss. When the roller brush is installed on the housing, the boss snaps into the slot, providing radial and axial positioning for the roller through the boss and slot, preventing the roller from misalignment or even falling off during the rotational cleaning process, thereby achieving the technical effect of improving the positioning accuracy of the roller brush and enhancing the operating stability of the roller brush.

[0045] In some technical solutions of the present application, optionally, the cleaning component further includes: a magnetic component, which is provided on the transmission component, and the magnetic component is used to magnetically attract the end cover.

[0046] In this technical solution, the cleaning assembly further includes a magnetic component, which is arranged on the side of the transmission component facing the end cap. The end cap is provided with a metal piece that can be attracted by the magnetic component, or at least a portion of the end cap is formed of a metal material.

[0047] After the roller brush is installed to the predetermined position, the magnetic component can attract the end cover or the metal parts on the end cover, thereby providing axial limitation for the roller brush, preventing it from being dislocated or even falling off during the rotating cleaning process, thereby achieving the technical effect of improving the positioning accuracy of the roller brush and improving the working stability of the roller brush.

[0048] In some technical solutions of the present application, optionally, the cleaning assembly further includes: a shock-absorbing component connected to the transmission component and located between the transmission component and the inner annular surface of the drum.

[0049] In this technical solution, a shock-absorbing component is also provided on the transmission component. The shock-absorbing component is located between the transmission component and the roller, and contacts the inner surface of the roller instead of the transmission component. The shock-absorbing component is formed from a vibration-absorbing material such as rubber. By providing the shock-absorbing component between the roller and the transmission component, the vibration of the roller brush on the housing is reduced, allowing the roller brush to rotate smoothly, thereby achieving the technical effect of improving the cleaning effect of the roller brush and reducing the operating noise of the roller brush.

[0050] Specifically, the shock absorbing component is a rubber pad installed at the end of the boss.

[0051] In some technical solutions of the present application, optionally, the first bracket includes a water inlet, a flow channel and a water outlet, and the flow channel connects the water inlet and the water outlet; the water inlet is used to connect to the water supply mechanism, and the water outlet is located above the cleaning component.

[0052] In this technical solution, a water inlet is provided on the first bracket, a flow channel connected to the water inlet is provided inside the first bracket, and a water outlet connected to the flow channel is provided below the first bracket facing the cleaning component.

[0053] Among them, the water inlet is used to connect the water supply mechanism on the cleaning equipment. The water supply mechanism can transport clean water to the flow channel through the water inlet. Then the clean water in the flow channel is discharged to the roller brush below through the water outlet to moisten the bristles on the outside of the roller brush, thereby softening stains and absorbing dust through the moistened bristles, thereby improving the cleaning effect of the cleaning mechanism.

[0054] Specifically, compared with the related technology of first spraying water on the designated area and then wiping the designated area with a roller brush, the present application chooses to wet the roller brush instead of wetting the designated area. On the one hand, it can reduce the water consumption of the cleaning mechanism to improve the endurance of the cleaning equipment. On the other hand, the present application can continuously wet the drum during the rotation of the roller brush, solving the problem of incomplete cleaning by a single water flow of spraying clean water on the ground and then cleaning it with a roller brush. On the other hand, wetting the roller brush instead of wetting the ground can avoid the formation of obvious water stains on the ground, thereby improving the cleaning effect.

[0055] In some technical solutions of the present application, optionally, the cleaning mechanism further includes: a wiper component connected to the first bracket and in contact with the cleaning assembly, the wiper component being used to scrape off waste water on the cleaning assembly, and the wiper component being also used to direct the waste water to the wastewater box.

[0056] In this technical solution, the cleaning mechanism further includes a wiper component, which is fixed on the first bracket. After the wiper component is assembled, the wiper component abuts against the roller on the roller brush.

[0057] Among them, on the circumference of the drum, the water outlet and the wiper component are spaced apart, and clean water first drips from the water outlet onto the bristles. After wetting the bristles, the drum drives the wet bristles to contact and wipe the designated area. After completing the contact and wiping action, the bristles carry away the stains and dust, and the clean water stored in the bristles is contaminated as waste water. In the subsequent rotation process, the wiper component squeezes out the waste water in the bristles through contact, and the bristles that discharge the waste water rotate to the bottom of the water outlet again and are wetted by the clean water discharged from the water outlet. The circulating roller brush can perform multiple live water cleanings on the designated area in a short time by continuously discharging clean water, thereby avoiding secondary pollution of the designated area by the waste water in the bristles, thereby improving the cleaning effect of the cleaning mechanism.

[0058] Furthermore, wastewater squeezed out by the wiper assembly is directed into a second water tank on the cleaning device. This second tank is used to store wastewater. After the cleaning process is complete, the user can either dump the wastewater from the second tank or drain it into a sewer via the base station. By directing the wastewater flow through the wiper assembly, secondary contamination of the designated area can be avoided.

[0059] In some technical solutions of the present application, optionally, the transmission assembly includes: a reel connected to the first motor; a wiring harness wound around the reel, and the first end of the wiring harness is connected to the reel; a third bracket connected to the second end of the wiring harness, and the third bracket is used to connect to the body.

[0060] In this technical solution, the transmission assembly includes a reel, a wiring harness and a third bracket.

[0061] Specifically, the reel is connected to the rotating shaft of the first motor, which can drive the reel to rotate. The third bracket is mounted on the body of the cleaning device, and the third bracket and the reel are connected by a wiring harness, wherein the wiring harness is wound around the reel. During operation, the first motor adjusts the length of the wiring harness between the reel and the third bracket by rotating the reel. Shortening the length can raise the cleaning assembly and clear the carpet. Correspondingly, extending the length of the wiring harness between the reel and the third bracket can lower the cleaning assembly, allowing it to re-engage the designated area and resume cleaning operations.

[0062] The reel and harness offer the advantages of low structural complexity and minimal space, reducing the cost and improving the compactness of the cleaning mechanism. Furthermore, compared to precision transmission structures like connecting rods and racks and pinions, the harness is less susceptible to entanglement with hair and can operate smoothly in harsh environments, thereby enhancing the practicality and reliability of the cleaning mechanism.

[0063] The second aspect of the present application provides a cleaning device, which includes: a body; a cleaning mechanism such as any of the above technical solutions, a frame connected to the body, and the frame can move relative to the body, and the second end of the transmission assembly is connected to the body.

[0064] In this technical solution, a cleaning device is defined that is provided with a cleaning mechanism in any of the above-mentioned technical solutions. Therefore, the cleaning device has the advantages of the cleaning mechanism in any of the above-mentioned technical solutions, and can achieve the technical effects that can be achieved by the cleaning mechanism in any of the above-mentioned technical solutions. To avoid repetition, it will not be repeated here.

[0065] Furthermore, the cleaning device further includes a body connected to the frame, and the frame is movable relative to the body. Specifically, the frame and the body are slidably connected, or the frame and the body are hinged to ensure that the frame can be raised and lowered relative to the body. The second end of the transmission assembly is fixed to the body, and the first motor is capable of adjusting the relative position between the body and the frame by driving the transmission assembly to achieve the lifting action.

[0066] When the cleaning device is a sweeping robot, the body is the robot base. When the cleaning device is a mopping machine, the body is the mop.

[0067] In some technical solutions of the present application, optionally, the width of the cleaning component is greater than the width of the machine body.

[0068] In this technical solution, the cleaning assembly is wider than the body, meaning it's flush with the sides of the body or extends beyond them. By having a cleaning assembly wider than the body, zero-edge cleaning can be achieved on both sides of the body, ensuring the cleaning device can effectively clean corners with the flush-with or extended cleaning assembly. This broadens the application scenarios of the cleaning device, eliminates blind spots, and improves its practicality.

[0069] In some technical solutions of the present application, optionally, the cleaning device further includes: a first water tank, arranged on the body; a water supply mechanism, connected to the first water tank and the cleaning component, and the water supply mechanism is used to supply water to the cleaning component.

[0070] In this technical solution, the machine body is further provided with a first water tank, which is used to store clean water, so that the cleaning device can be used without a water source.

[0071] On this basis, a water supply mechanism is also provided on the machine body, one end of the water supply mechanism is connected to the first water tank, and the other end of the water supply mechanism is connected to the water inlet on the first bracket. The water supply mechanism can transport clean water in the first water tank to the water inlet, thereby wetting the roller brush with clean water to achieve live water cleaning of the roller brush.

[0072] Specifically, the water supply mechanism includes a water pump and a pipeline. The pipeline is connected to the first water tank and the water inlet, and the water pump is arranged on the pipeline.

[0073] In some technical solutions of the present application, optionally, the cleaning device further includes: a second water tank, provided on the machine body, and the second water tank is used to store wastewater discharged by the cleaning component.

[0074] In this technical solution, the cleaning equipment also includes a second water tank, which is installed on the machine body and is arranged opposite to the wiper component on the cleaning mechanism. After the wiper component scrapes out the waste water in the roller brush, the waste water flows along the wiper component to the second water tank, thereby centrally storing the waste water through the second water tank to avoid secondary pollution caused by the waste water.

[0075] The second water tank and the machine body are detachably connected to facilitate users to dump waste water in the second water tank.

[0076] In some technical solutions of the present application, optionally, the cleaning component includes a roller body, a driving member and blades; an installation cavity is provided inside the roller body; the driving member is located in the installation cavity, and the driving member is used to drive the roller body to rotate, and there is a gap between the driving member and the inner side wall of the installation cavity; the blades are located in the installation cavity, and the blades are detachably connected to the roller body through a connecting component, so that the blades rotate along with the roller body.

[0077] According to the cleaning assembly of the embodiment of the present application, there are at least the following beneficial effects: the driving member drives the roller body to rotate, and since the blades rotate along with the roller body, the rotation of the blades drives the air in the installation cavity to flow, and the air flows in the gap between the driving member and the inner side wall of the installation cavity. The flowing air dissipates heat from the driving member, reduces the temperature of the driving member, and reduces the occurrence of overheating of the driving member. In the cleaning assembly of the above embodiment, the blades are detachable relative to the roller body, which means that the blades can be processed independently, reducing the processing difficulty, and during later maintenance, the roller body or the blades can be replaced separately, without having to replace both as a whole, reducing production and later maintenance costs. The above cleaning assembly uses the cleaning assembly's own driving member to drive the blades to rotate, so as to enhance the heat dissipation effect of the driving member itself, so that the cleaning assembly can achieve the purpose of enhancing the heat dissipation effect of the built-in driving member through a simple structure, and the overall cost is not significantly increased, and the space occupied by the cleaning assembly is not significantly increased, which is highly practical.

[0078] In some technical solutions of the present application, optionally, the connecting assembly includes a first mounting bracket, the first mounting bracket is fixedly mounted in cooperation with the inner side wall of the mounting cavity, and the blade is mounted on the first mounting bracket.

[0079] In some technical solutions of the present application, optionally, the first mounting bracket is cylindrical, a convex rib is provided on the outer side wall of the first mounting bracket, and a limiting groove cooperating with the convex rib is provided on the inner side wall of the mounting cavity.

[0080] In some technical solutions of the present application, optionally, the first mounting bracket includes a base plate and a side plate, the base plate is provided with a mounting hole, the rib is provided on the outer side of the side plate, and the blade is fixed to the mounting hole through a threaded connection.

[0081] In some technical solutions of the present application, optionally, the cleaning assembly also includes a roller cover, a second mounting bracket is installed on the roller cover, the driving member is fixedly installed on the second mounting bracket, the end of the roller body away from the second mounting bracket can be rotatably connected to a limiting end cover, the limiting end cover is installed on the roller cover, and the limiting end cover is provided with a limiting portion for preventing the roller body from moving axially.

[0082] In some technical solutions of the present application, optionally, the limiting end cover can be detachably mounted on the roller cover.

[0083] In some technical solutions of the present application, optionally, the base plate is also provided with a connecting rod, the connecting rod is fixedly connected to the threaded connector, a third bearing is provided between the limiting end cover and the connecting rod, and a fourth bearing is provided between the second mounting bracket and the inner wall of the mounting cavity.

DETAILED DESCRIPTION

[0108] In order to more clearly understand the above-mentioned objects, features and advantages of the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other in the absence of conflict.

[0109] In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present application is not limited to the specific embodiments disclosed below.

[0110] The cleaning mechanism 800 and the cleaning device 700 according to some embodiments of the present application are described below with reference to FIG. 1 to FIG. 19 .

[0111] As shown in Figures 1, 2 and 3, an embodiment of the present application provides a cleaning mechanism 800, which is used for a cleaning device 700. The cleaning device 700 includes a body 210, and the cleaning mechanism 800 includes: a frame 810; a cleaning component 820, connected to the frame 810; a first motor 830, disposed in the frame 810 and connected to the frame 810; a transmission component 140, wherein the first end of the transmission component 140 is connected to the first motor 830, and the second end of the transmission component 140 is used to connect to the body 210, and the first motor 830 drives the frame 810 to move relative to the body 210 through the transmission component 140.

[0112] FIG1 shows a schematic structural diagram of a cleaning device 700 according to an embodiment of the present application.

[0113] FIG2 shows a schematic structural diagram of a cleaning device 700 according to an embodiment of the present application.

[0114] FIG3 shows an exploded view of a cleaning mechanism 800 according to one embodiment of the present application.

[0115] In this embodiment, a cleaning mechanism 800 is defined. The cleaning mechanism 800 is applied to the cleaning device 700. The cleaning device 700 performs cleaning operations on areas such as the floor, tabletop, and furniture surface through the cleaning mechanism 800.

[0116] Specifically, the cleaning mechanism 800 includes a frame 810 and a cleaning assembly 820. The frame 810 positions, supports, and protects the other structures on the cleaning mechanism 800. The cleaning assembly 820 is connected to the frame 810 and can clean a designated area through rotation, reciprocating motion, or other motions, such as wiping the floor with the rotating roller brush 126.

[0117] Among them, the cleaning component 820 maintains contact with the designated area below during the cleaning operation, and the cleaning component 820 usually carries waste water for wiping dust. If the cleaning equipment 700 drives the cleaning component 820 to move to areas such as carpets that are not suitable for cleaning with the wet cleaning component 820, the wet cleaning component 820 may drag down the hair on the carpet, or the waste water carried by the cleaning component 820 may contaminate the carpet, causing the dust in the carpet to adhere to the carpet hair under the action of the waste water.

[0118] In this regard, the cleaning mechanism 800 defined in the present application also includes a first motor 830 and a transmission assembly 140. The first motor 830 is connected to the frame 810, the first end of the transmission assembly 140 is connected to the power output end of the first motor 830, and the second end of the transmission assembly 140 is connected to the body 210 on the cleaning device 700. After the first motor 830 is turned on, the first motor 830 drives the transmission assembly 140 to move, thereby driving the frame 810 and the first motor 830 and the cleaning assembly 820 on the frame 810 to move relative to the body 210. Specifically, the cleaning assembly 820 can be driven to rise and fall relative to the designated area by the first motor 830 and the transmission assembly 140. When encountering a scene such as a carpet that is not suitable for cleaning by the cleaning assembly 820, the cleaning assembly 820 is driven to rise to avoid the designated area. When the cleaning device 700 moves back to an area suitable for wiping by the cleaning assembly 820, the cleaning assembly 820 is lowered so that the cleaning assembly 820 contacts the designated area again to resume the cleaning operation.

[0119] It can be seen that by setting the first motor 830 and the transmission assembly 140, the cleaning mechanism 800 has a lifting function, thereby solving the technical defects of the related technology such as limited application scenarios, easy contamination of carpets, and inconvenience to users through the lifting function, thereby optimizing the structure of the cleaning mechanism 800, improving the practicality and reliability of the cleaning mechanism 800, broadening the application scenarios of the cleaning equipment 700, and improving the user experience.

[0120] On this basis, the first motor 830 is integrated into the frame 810, and the first motor 830 rises and falls synchronously with the frame 810. By arranging the first motor 830 within the frame 810, on the one hand, a modular design and a hidden design of the motor and the cleaning assembly 820 can be achieved, so that the cleaning mechanism 800 can achieve the lifting function without relying on the drive structure on the cleaning device 700. On the other hand, the first motor 830 reasonably utilizes the space inside the frame 810 and does not encroach on the space outside the frame 810, thereby eliminating the need for reserving a motor installation position and a motor avoidance position on the cleaning device 700, thereby achieving the technical effect of improving the structural compactness of the cleaning mechanism 800 and the cleaning device 700, and providing convenient conditions for the miniaturization design of the cleaning device 700.

[0121] Specifically, the transmission component 140 can realize the lifting function through structures such as connecting rods, gears, racks, screws, reels 142, and wiring harnesses 144. This embodiment does not impose rigid restrictions on the specific structural form of the transmission component 140, and it is sufficient to meet the lifting transmission requirements.

[0122] As shown in Figures 3 and 4, in some embodiments of the present application, optionally, the frame 810 includes: a first bracket 112; a second bracket 114, connected to the first bracket 112, the second bracket 114 includes a mounting groove 1142, the first motor 830 is disposed in the mounting groove 1142, and the cleaning component 820 is connected to the first bracket 112 and / or the second bracket 114; wherein the cleaning component 820 and the second bracket 114 are located below the first bracket 112.

[0123] FIG4 shows an exploded view of a cleaning mechanism 800 according to one embodiment of the present application.

[0124] In this embodiment, the frame 810 includes a first bracket 112 and a second bracket 114 .

[0125] Among them, the cleaning component 820 is fixed under the first bracket 112, and the first bracket 112 is plate-shaped. The plate-shaped first bracket 112 covers the upper area of ​​the cleaning component 820. The first bracket 112 can play a shielding and protective role above the cleaning component 820, which can prevent the cleaning component 820 from throwing waste water upward during the cleaning operation, thereby improving the practicality of the cleaning mechanism 800.

[0126] Second bracket 114 is connected to first bracket 112 and is also positioned below first bracket 112. First bracket 112 also shields and protects second bracket 114, reducing the possibility of damage or malfunction of first motor 830. Second bracket 114 and cleaning assembly 820 are positioned side by side below first bracket 112 to effectively utilize the space below first bracket 112 and enhance the compactness of cleaning mechanism 800.

[0127] Specifically, the second bracket 114 is provided with a mounting slot 1142, the shape of which matches the outer contour of the first motor 830. During assembly, the first motor 830 is first inserted into the mounting slot 1142, and then the second bracket 114 and the first motor 830 are connected via screws 160. The second bracket 114 provides positioning and protection outside the first motor 830. On the one hand, it ensures that the first motor 830 is positioned in the predetermined working position, and on the other hand, it reduces the probability of the first motor 830 being corroded by external wastewater, thereby achieving the technical effect of improving the positioning accuracy of the first motor 830 and enhancing the structural stability and reliability of the cleaning mechanism 800.

[0128] As shown in FIG. 3 and FIG. 8 , in some embodiments of the present application, optionally, the cleaning assembly 820 covers the mounting slot 1142 ; the second bracket 114 further includes a through hole 1144 , and the transmission assembly 140 is disposed through the through hole 1144 .

[0129] FIG8 shows a schematic structural diagram of a framework 810 according to an embodiment of the present application.

[0130] In this embodiment, the cleaning assembly 820 is opposite to the opening of the mounting slot 1142. After the cleaning assembly 820 is assembled, the cleaning assembly 820 covers the opening of the mounting slot 1142 to limit the first motor 830 in the mounting slot 1142, thereby preventing the first motor 830 from being misplaced or even falling out of the mounting slot 1142. During the assembly process, the first motor 830 must first be installed into the mounting slot 1142, and then the cleaning assembly 820 must be fixed to the opening of the mounting slot 1142. In this way, the cleaning assembly 820 is rationally utilized to achieve the technical effect of improving the structural compactness of the cleaning mechanism 800.

[0131] On this basis, a through hole 1144 is provided on the second bracket 114, which connects the mounting groove 1142 and the external space of the second bracket 114. The first end of the transmission assembly 140 is connected to the first motor 830 in the mounting groove 1142 through the through hole 1144, so as to ensure that power can be transmitted to the outside of the second bracket 114 through the transmission assembly 140 while hiding the first motor 830.

[0132] As shown in FIG. 1 , in some embodiments of the present application, optionally, the cleaning assembly 820 includes: a first cleaning assembly 121 connected to the second bracket 114 ; a second cleaning assembly 122 connected to the second bracket 114 , and the second bracket 114 is located between the first cleaning assembly 121 and the second cleaning assembly 122 .

[0133] In this embodiment, the cleaning component 820 includes a first cleaning component 121 and a second cleaning component 122, which are symmetrically distributed on the left and right sides of the first motor 830. The first cleaning component 121 is connected to the first end of the opening of the mounting groove 1142 on the second bracket 114, and the second cleaning component 122 is connected to the second end of the opening facing away from the mounting groove 1142.

[0134] By clamping the second bracket 114 and the first motor 830 between the first cleaning assembly 121 and the second cleaning assembly 122, on the one hand, it is possible to ensure that both ends of the cleaning mechanism 800 have cleaning capabilities, preventing the built-in first motor 830 from forming a cleaning blind spot on the cleaning mechanism 800, allowing the cleaning mechanism 800 to effectively clean areas such as corners and gaps. On the other hand, the first cleaning assembly 121 and the second cleaning assembly 122 symmetrically distributed on the left and right sides of the first motor 830 can balance the weight of the left and right sides of the transmission assembly 140, preventing the cleaning mechanism 800 from tilting or even tipping during the lifting process, thereby achieving the technical effect of improving the structural stability of the cleaning mechanism 800 and the smoothness of the lifting.

[0135] As shown in Figures 5 and 10, in some embodiments of the present application, optionally, the cleaning component 820 includes: a shell 123, connected to the second bracket 114; a second motor 124, disposed in the shell 123; a transmission component 125, connected to the second motor 124; a roller brush 126, sleeved on the outside of the shell 123 and connected to the transmission component 125, and the second motor 124 drives the roller brush 126 to rotate relative to the shell 123 through the transmission component 125.

[0136] FIG5 illustrates an exploded view of a cleaning assembly 820 according to one embodiment of the present application.

[0137] FIG10 shows a schematic structural diagram of a housing 123 according to an embodiment of the present application.

[0138] In this embodiment, the cleaning assembly 820 includes a housing 123 , a second motor 124 , a transmission component 125 and a roller brush 126 .

[0139] The housing 123 is connected to the second bracket 114. A cavity is formed in the housing 123. The second motor 124 is disposed in the cavity. The power output end of the second motor 124 is connected to a transmission component 125, and the transmission component 125 is located outside the housing 123. The housing 123 is cylindrical, and the roller brush 126 is mounted on the outside of the housing 123. The housing 123 can provide protection for the second motor 124 inside, and the housing 123 can also provide support and positioning for the roller brush 126 outside.

[0140] At the same time, the transmission component 125 is connected to the roller brush 126, and the second motor 124 can drive the roller brush 126 to rotate relative to the shell 123 through the transmission component 125, so that the rotating roller brush 126 wipes the stains and dust in the designated area, thereby realizing the cleaning function of the cleaning mechanism 800.

[0141] During assembly, the roller brush 126 is fitted onto a predetermined position outside the housing 123 to complete the connection between the transmission component 125 and the roller brush 126. Specifically, the transmission component 125 and the roller brush 126 can be connected through an interference fit, or through a snap-fit ​​structure such as ribs or grooves, with no rigid restrictions. Thus, the roller brush 126 can be easily assembled and disassembled through a simple plug-in and pull-out action, providing convenient conditions for cleaning or replacing the roller brush 126, thereby achieving the technical effect of optimizing the structure of the cleaning assembly 820 and enhancing the user experience.

[0142] As shown in Figures 3 and 5, in some embodiments of the present application, optionally, the cleaning component 820 also includes: a bearing 128, which is provided in the shell 123 and located between the shell 123 and the roller brush 126; wherein the outer ring of the bearing 128 is interference fit with the roller brush 126.

[0143] In this embodiment, the cleaning component 820 also includes a bearing 128, which is arranged between the shell 123 and the roller brush 126. Specifically, the bearing 128 is first sleeved on the outside of the shell 123. In the process of sleeved the roller brush 126 on the outside of the shell 123, the roller brush 126 is also sleeved on the outside of the bearing 128. The outer ring of the bearing 128 and the inner ring surface of the roller brush 126 are connected by an interference fit. In the process of the second motor 124 driving the roller brush 126 to rotate through the transmission component 125, the outer ring of the bearing 128 rotates along with the roller brush 126 relative to the inner ring of the bearing 128.

[0144] It can be seen that by setting the bearing 128, on the one hand, the bearing 128 can provide support for the roller brush 126 and reduce the possibility of the roller brush 126 rotating obliquely. On the other hand, the bearing 128 can reduce the rotational resistance of the roller brush 126 to increase the rotation speed of the roller brush 126 and improve the energy efficiency ratio of the second motor 124.

[0145] As shown in FIG. 5 , in some embodiments of the present application, optionally, there are multiple bearings 128 , and the multiple bearings 128 are spaced apart in the axial direction of the housing 123 .

[0146] In this embodiment, each cleaning assembly 820 includes a plurality of bearings 128 . The plurality of bearings 128 are sleeved on the outside of the housing 123 , and the plurality of bearings 128 are spaced apart in the axial direction of the housing 123 .

[0147] By arranging multiple bearings 128 arranged at intervals on the outside of the shell 123, the multiple bearings 128 can jointly support the roller brush 126 to ensure the smooth rotation of the roller brush 126, avoid the roller brush 126 from rotating at an angle or shaking violently, and thereby achieve the technical effect of improving the structural stability of the cleaning mechanism 800.

[0148] Specifically, the bearing 128 includes a first bearing 1281 and a second bearing 1284. The first bearing 1281 is fixed at the tail of the shell 123, and the second bearing 1284 is fixed at the front end of the shell 123 to support the roller brush 126 mounted on the outside of the shell 123 on the front and rear sides of the shell 123.

[0149] As shown in Figure 7, in some embodiments of the present application, optionally, the roller brush 126 includes: a roller 1262, which is mounted on the outside of the shell 123, and the shell 123 can be inserted into the roller 1262 from the first end of the roller 1262, and the transmission component 125 is connected to the inner annular surface of the roller 1262; bristles 1264, which are arranged on the outer annular surface of the roller 1262; and an end cover 1266, which is connected to the roller 1262 and covers the second end of the roller 1262.

[0150] FIG. 7 shows an exploded view of the roller brush 126 according to one embodiment of the present application.

[0151] In this embodiment, the roller brush 126 includes a roller 1262 , bristles 1264 , and an end cap 1266 .

[0152] Drum 1262 is hollow and cylindrical. It fits over the outside of housing 123 through an opening at its first end. An end cap 1266 is connected to the second end of drum 1262. Covering the opening at the second end of drum 1262, end cap 1266 shields and protects second motor 124 and transmission component 125 inside drum 1262, thereby reducing the risk of failure of second motor 124. The end cap 1266 and drum 1262 are detachably connected, making it easier for the user to clean and maintain the internal structure of drum 1262.

[0153] On this basis, the outer side of the roller 1262 is covered with bristles 1264. During the rotation, the bristles 1264 rotate synchronously. After the bristles 1264 contact the designated area, they carry away the dirt and dust attached to the designated area through friction, thereby achieving a cleaning effect. In addition, the densely distributed bristles 1264 can also store a certain amount of water. During the cleaning process, the carried water softens the dirt and absorbs the dust, thereby improving the cleaning effect of the cleaning mechanism 800.

[0154] In some embodiments of the present application, optionally, the transmission component 125 is snap-fitted with the inner annular surface of the roller 1262 , or the transmission component 125 is interference fit with the inner annular surface of the roller 1262 .

[0155] In this embodiment, the transmission component 125 and the roller 1262 are connected by an interference fit or a snap fit.

[0156] Specifically, a boss is provided on the circumference of the transmission component 125, and a slot that matches the boss is provided on the inner annular surface of the roller 1262. When the roller brush 126 is mounted on the housing 123, the boss snaps into the slot. The boss and slot provide radial and axial positioning for the roller 1262, preventing it from misaligning or even falling off during the rotational cleaning process. This improves the positioning accuracy of the roller brush 126 and enhances its operational stability.

[0157] As shown in FIG. 5 and FIG. 7 , in some embodiments of the present application, optionally, the cleaning assembly 820 further includes: a magnetic component 1268 , which is provided on the transmission component 125 , and the magnetic component 1268 is used to magnetically attract the end cover 1266 .

[0158] In this embodiment, the cleaning assembly 820 further includes a magnetic component 1268, which is disposed on a side of the transmission component 125 facing the end cap 1266. The end cap 1266 is provided with a metal member that can be attracted by the magnetic component 1268, or at least a portion of the end cap 1266 is formed of a metal material.

[0159] After the roller brush 126 is installed to the predetermined position, the magnetic component 1268 can attract the end cover 1266 or the metal parts on the end cover 1266, thereby providing axial limitation for the roller brush 126, preventing the roller from being misplaced or even falling off during the rotation and cleaning process, thereby achieving the technical effect of improving the positioning accuracy of the roller brush 126 and improving the working stability of the roller brush 126.

[0160] As shown in FIG. 5 , in some embodiments of the present application, optionally, the cleaning assembly 820 further includes: a shock absorbing component 1269 connected to the transmission component 125 and located between the transmission component 125 and the inner annular surface of the roller 1262 .

[0161] In this embodiment, a shock-absorbing component 1269 is further provided on the transmission component 125. The shock-absorbing component 1269 is located between the transmission component 125 and the roller 1262. The shock-absorbing component 1269 replaces the transmission component 125 and contacts the inner annular surface of the roller 1262. The shock-absorbing component 1269 is formed from a vibration-absorbing material such as rubber. By providing the shock-absorbing component 1269 between the roller 1262 and the transmission component 125, the vibration of the roller brush 126 on the housing 123 is reduced, allowing the roller brush 126 to rotate smoothly, thereby achieving the technical effect of improving the cleaning effect of the roller brush 126 and reducing the operating noise of the roller brush 126.

[0162] Specifically, the shock absorbing component 1269 is a rubber pad installed at the end of the boss.

[0163] As shown in Figure 6, in some embodiments of the present application, optionally, the first bracket 112 includes a water inlet 1122, a flow channel 1123 and a water outlet, and the flow channel 1123 connects the water inlet 1122 and the water outlet; the water inlet 1122 is used to connect to the water supply mechanism 230, and the water outlet is located above the cleaning component 820.

[0164] FIG6 shows an exploded view of a cleaning mechanism 800 according to one embodiment of the present application.

[0165] In this embodiment, a water inlet 1122 is provided on the first bracket 112 , a flow channel 1123 connected to the water inlet 1122 is provided inside the first bracket 112 , and a water outlet connected to the flow channel 1123 is provided below the first bracket 112 facing the cleaning component 820 .

[0166] Among them, the water inlet 1122 is used to connect the water supply mechanism 230 on the cleaning equipment 700. The water supply mechanism 230 can transport clean water to the flow channel 1123 through the water inlet 1122. Thereafter, the clean water in the flow channel 1123 is discharged to the roller brush 126 below through the water outlet to moisten the bristles 1264 on the outside of the roller brush 126, thereby softening stains and absorbing dust through the moistened bristles 1264, thereby improving the cleaning effect of the cleaning mechanism 800.

[0167] Specifically, compared with the related art of first spraying water on the designated area and then wiping the designated area with the roller brush 126, the present application chooses to wet the roller brush 126 instead of wetting the designated area. On the one hand, it can reduce the water consumption of the cleaning mechanism 800 to improve the endurance of the cleaning equipment 700. On the other hand, the present application can continuously wet the roller 1262 during the rotation of the roller brush 126, solving the problem of incomplete cleaning by a single water flow of spraying clean water on the ground and then cleaning it with the roller brush 126. On the other hand, wetting the roller brush 126 instead of wetting the ground can avoid the formation of obvious water stains on the ground, thereby improving the cleaning effect.

[0168] As shown in Figure 6, in some embodiments of the present application, optionally, the cleaning mechanism 800 also includes: a wiper component 150, which is connected to the first bracket 112 and contacts the cleaning assembly 820, and the wiper component 150 is used to scrape off the waste water on the cleaning assembly 820. The wiper component 150 is also used to guide the waste water to the wastewater box.

[0169] In this embodiment, the cleaning mechanism 800 further includes a wiper component 150 , which is fixed to the first bracket 112 . After the wiper component 150 is assembled, the wiper component 150 abuts against the roller 1262 on the roller brush 126 .

[0170] Among them, on the circumference of the roller 1262, the water outlet and the wiper component 150 are spaced apart, and the clean water first drips from the water outlet onto the bristles 1264. After wetting the bristles 1264, the roller 1262 drives the wet bristles 1264 to contact and wipe the designated area. After completing the contact and wiping action, the bristles 1264 carry away the stains and dust, and the clean water stored in the bristles 1264 is contaminated as waste water. During the subsequent rotation process, the wiper component 150 squeezes out the waste water in the bristles 1264 through contact, and the bristles 1264 that discharge the waste water rotate to the bottom of the water outlet again and are wetted by the clean water discharged from the water outlet. The circulating roller brush 126 can perform multiple live water cleanings on the designated area in a short time by continuously discharging clean water, thereby avoiding the waste water in the bristles 1264 causing secondary pollution to the designated area, thereby improving the cleaning effect of the cleaning mechanism 800.

[0171] On this basis, the wastewater squeezed out by the wiper component 150 can be directed by the wiper component 150 to the second water tank 240 on the cleaning device 700. The second water tank 240 is used to store wastewater. After the cleaning operation is completed, the user can actively dump the wastewater in the second water tank 240 or discharge the wastewater into the sewer through the base station. By guiding the flow of wastewater by the wiper component 150, secondary contamination of the designated area by the wastewater can be avoided.

[0172] As shown in Figures 3 and 9, in some embodiments of the present application, optionally, the transmission assembly 140 includes: a reel 142, connected to the first motor 830; a wiring harness 144, wound around the reel 142, and a first end of the wiring harness 144 is connected to the reel 142; a third bracket 146, connected to the second end of the wiring harness 144, and the third bracket 146 is used to connect to the body 210.

[0173] FIG9 shows a schematic structural diagram of a reel 142 according to an embodiment of the present application.

[0174] In this embodiment, the transmission assembly 140 includes a reel 142 , a wire harness 144 , and a third bracket 146 .

[0175] Specifically, the reel 142 is connected to the rotating shaft of the first motor 830, and the first motor 830 can drive the reel 142 to rotate. The third bracket 146 is installed on the body 210 of the cleaning device 700, and the third bracket 146 and the reel 142 are connected by a wire harness 144, wherein the wire harness 144 is wound around the reel 142. During operation, the first motor 830 adjusts the length of the wire harness 144 between the reel 142 and the third bracket 146 by driving the reel 142 to rotate. The cleaning component 820 can be lifted by shortening the length so that the cleaning component 820 avoids the carpet. Correspondingly, the length of the wire harness 144 between the reel 142 and the third bracket 146 can be extended to lower the cleaning component 820 so that the cleaning component 820 contacts the designated area again to resume the cleaning operation.

[0176] The reel 142 and harness 144 have the advantages of low structural complexity and small space occupation, which helps reduce the cost of cleaning mechanism 800 and improve the structural compactness of cleaning mechanism 800. Furthermore, compared with precision transmission structures such as connecting rods, gear racks, etc., the harness 144 will not get stuck due to hair entanglement, and can maintain smooth operation in harsh environments, thereby achieving the technical effect of improving the practicality and reliability of cleaning mechanism 800.

[0177] As shown in Figures 1 and 2, an embodiment of the present application provides a cleaning device 700, which includes: a body 210; a cleaning mechanism 800 such as any of the above embodiments, a frame 810 connected to the body 210, and the frame 810 can move relative to the body 210, and the second end of the transmission assembly 140 is connected to the body 210.

[0178] In this embodiment, a cleaning device 700 is defined that is provided with the cleaning mechanism 800 in any of the above embodiments. Therefore, the cleaning device 700 has the advantages of the cleaning mechanism 800 in any of the above embodiments, and can achieve the technical effects that can be achieved by the cleaning mechanism 800 in any of the above embodiments. To avoid repetition, it will not be repeated here.

[0179] On this basis, the cleaning device 700 further includes a body 210, which is connected to a frame 810, and the frame 810 can move relative to the body 210. Specifically, the frame 810 and the body 210 are slidably connected, or the frame 810 and the body 210 are hinged to ensure that the frame 810 can be raised and lowered relative to the body 210. The second end of the transmission assembly 140 is fixed to the body 210, and the first motor 830 can adjust the relative position between the body 210 and the frame 810 by driving the transmission assembly 140 to complete the lifting action.

[0180] When the cleaning device 700 is a sweeping robot, the body 210 is a robot base, and a driving wheel 212 is provided at the bottom of the body 210. When the cleaning device 700 is a mopping machine, the body 210 is a mop.

[0181] As shown in FIG. 1 , in some embodiments of the present application, optionally, the width of the cleaning assembly 820 is greater than the width of the body 210 .

[0182] In this embodiment, the width of the cleaning assembly 820 is greater than the width of the body 210, that is, the cleaning assembly 820 is flush with both sides of the body 210, or the cleaning assembly 820 extends beyond both sides of the body 210. By providing a cleaning assembly 820 having a width greater than that of the body 210, zero-edge cleaning can be achieved on both sides of the body 210, ensuring that the cleaning device 700 can effectively clean corner areas through the cleaning assembly 820 that is flush with or extends beyond the body 210, thereby achieving the technical effect of broadening the application scenarios of the cleaning device 700, eliminating cleaning blind spots, and improving the practicality of the cleaning device 700.

[0183] As shown in Figure 1, in some embodiments of the present application, optionally, the cleaning device 700 also includes: a first water tank 220, which is arranged on the body 210; a water supply mechanism 230, which is connected to the first water tank 220 and the cleaning component 820, and the water supply mechanism 230 is used to supply water to the cleaning component 820.

[0184] In this embodiment, the body 210 is further provided with a first water tank 220, which is used to store clean water, so that the cleaning device 700 can be used without a water source.

[0185] On this basis, a water supply mechanism 230 is also provided on the body 210. One end of the water supply mechanism 230 is connected to the first water tank 220, and the other end of the water supply mechanism 230 is connected to the water inlet 1122 on the first bracket 112. The water supply mechanism 230 can transport the clean water in the first water tank 220 to the water inlet 1122, thereby wetting the roller brush 126 with clean water to achieve live water cleaning of the roller brush 126.

[0186] Specifically, the water supply mechanism 230 includes a water pump and a pipeline. The pipeline is connected to the first water tank 220 and the water inlet 1122, and the water pump is arranged on the pipeline.

[0187] As shown in FIG. 1 , in some embodiments of the present application, optionally, the cleaning device 700 further includes: a second water tank 240 , which is provided on the body 210 , and the second water tank 240 is used to store waste water discharged by the cleaning component 820 .

[0188] In this embodiment, the cleaning device 700 also includes a second water tank 240, which is installed on the body 210, and the second water tank 240 is arranged opposite to the wiper component 150 on the cleaning mechanism 800. After the wiper component 150 scrapes out the waste water in the roller brush 126, the waste water flows along the wiper component 150 to the second water tank 240, thereby centrally storing the waste water through the second water tank 240 to avoid secondary pollution caused by the waste water.

[0189] The second water tank 240 and the body 210 are detachably connected to facilitate users to pour out the waste water in the second water tank 240 .

[0190] As shown in Figure 1, the cleaning mechanism 800 is installed at the rear of the body 210. The cleaning mechanism 800 is the same width as the body 210, or the width of the cleaning mechanism 800 is greater than the width of the body 210, thereby achieving double zero edge cleaning. The cleaning mechanism 800 is installed on the body 210 through a connecting pin 147, powered by an internal first motor 830, and is raised and lowered by changing the length of the wiring harness 144. The third bracket 146 is fixed to the body 210 by a screw 160. Clean water is stored in the first water tank 220 and flows into the flow channel 1123 in the first bracket 112 through the water supply mechanism 230. After cleaning is completed, the dirty water is scraped off by the wiper component 150, and the dirty water is collected by the second water tank 240. In other embodiments, the cleaning mechanism 800 can also be installed at the front or middle of the body 210.

[0191] The body 210 is electrically connected to the first motor 830 via the lifting motor line 170, electrically connected to the second motor 124 in the first cleaning assembly 121 via the left motor line 171, and electrically connected to the second motor 124 in the second cleaning assembly 122 via the right motor line 172. The cleaning device 700 stores dust collected during the cleaning process through the dust box 250.

[0192] As shown in Figure 3, the roller brush 126 is installed on the frame 810. Before installation, the lifting motor line 170 is first inserted into the specified position, and then the first motor 830 is installed, and then the reel 142 is installed, and then the screw 160 is installed, and then the roller fixing bracket 129 is installed and fastened with the screw 160, and then the first bearing bracket 1282 is installed, and then the second bearing bracket 1283, the first bearing 1281, and the floor brush motor back shell 1232 are assembled together, and then the screw 160 is screwed into the floor brush motor back shell 1232, and finally the installation of the second motor 124 and the roller brush 126 is completed.

[0193] As shown in Figure 5, the first bearing 1281 is installed inside the second bearing bracket 1283, and then the two are installed on the rear housing 1232 of the floor brush motor, and then the screws 160 are screwed in. There is a snap-fit ​​structure on the second bearing bracket 1283, which serves to fix the first bearing 1281 while supporting the roller 1262. The second motor 124 is installed in the rear housing 1232 of the floor brush motor, and then the front housing 1234 of the floor brush motor is buckled, and then the screws 160 are screwed in. These screws 160 are fixed on the second motor 124 to fix the second motor 124. The second bearing 1284 is then installed. The installation method is the same as that of the first bearing 1281, and it is positioned by the third bearing bracket 1285 and the fourth bearing bracket 1286. The transmission component 125 is installed on the output shaft end of the second motor 124 to transmit power to the roller 1262. Transmission component 125 is equipped with a vibration damping member to provide vibration isolation. Furthermore, a magnetic member 1268 is mounted in a groove at the outer end of transmission component 125. Magnetic member 1268 cooperates with the magnet on end cap 1266 to limit the axial movement of roller 1262. Screw 160 secures transmission component 125 and magnetic member 1268 to the output shaft of second motor 124.

[0194] A pad 132 is provided between the second bracket 114 and the rear housing 1232 of the floor brush motor.

[0195] As shown in Figure 6, clean water flows from the water inlet 1122 into the flow channel 1123, then flows through the water outlet connected to the flow channel 1123 to the roller brush 126. After cleaning the floor, the waste water is scraped off by the wiper component 150 and collected by the second water tank 240. The wiper component 150 is fixed by the pressure plate 152. The first bracket 112 forms the flow channel 1123 through the water channel cover plate 1121 and the groove.

[0196] As shown in Figure 7, the roller brush 126 consists of a roller 1262 and bristles 1264 attached to it. An end cap 1266 is mounted on one end of the roller 1262 to provide a seal. A handle on the end cap 1266 facilitates removal of the roller 1262. A magnet is mounted on the end cap 1266, which cooperates with a magnetic component 1268 in the motor module to limit the axial movement of the roller 1262.

[0197] As shown in Figure 8, the wiring holes on the floor brush fixing bracket are shown. The wiring holes include a through hole 1144, a left motor wire hole 1145, a lift motor wire hole 1146, and a right motor wire hole 1147. Through hole 1144 is used to install the wiring harness 144, the left motor wire hole 1145 is used to install the left motor wire 171, the lift motor wire hole 1146 is used to install the lift motor wire 170, and the right motor wire hole 1147 is used to install the right motor wire 172.

[0198] The first bracket 112 is provided with a pin connection hole 1124 .

[0199] The arrangement of the routing holes is not limited to the pattern shown in FIG8 .

[0200] As shown in FIG9 , the reel 142 of the application is shown, and the shaft of the second motor 124 is passed through the shaft hole 1422 . The positions of the lifting wire fixed end 1423 and the lifting wire through hole 1424 are not limited to the form shown in FIG9 .

[0201] The cleaning robots in the related art have a wide variety of mop cloth styles, including the common flat block-shaped mop tray, bilaterally symmetrical mop tray, and roller-shaped mop drum. In addition to having better cleaning and anti-smudge effects, the roller-shaped mop drum has the advantage of being easily combined with a running water cleaning function. That is, when the cleaning robot performs a cleaning task, the drum rotates to clean the floor while clean water is sprayed onto the surface of the mop on the drum for cleaning. The dirty water is then scraped off and collected and pumped away. The drum is generally large in size. In order to make full use of the space, the drive motor is generally configured to be built-in, that is, the drive motor is arranged inside the drum. However, this also brings some new problems. For example, the motor is in a relatively closed space, the heat dissipation effect is poor, and the motor may overheat. For this reason, there is a solution in the related art to set a spiral protrusion on the inner wall of the drum to guide the air flow. However, the production and processing of the drum in this technical solution is relatively difficult, resulting in increased initial production and subsequent maintenance costs.

[0202] As shown in Figures 11, 12, 13, 14, 15, 16, and 17, in some embodiments of the present application, the cleaning assembly 820 includes a drum body 100, a driving member 200, and a blade 300. The drum body 100 is cylindrical and has an internal mounting cavity 110. The mounting cavity 110 extends through the drum body 100, and a gap is formed between the driving member 200 and the inner wall of the mounting cavity 110. The driving member 200 is located in the mounting cavity 110 and is fixedly mounted to the cleaning device 700 via a mounting structure. The driving member 200 is used to drive the drum body 100 to rotate. The blade 300 is located in the mounting cavity 110 and is detachably connected to the drum body 100 via a connecting assembly; and the blade 300 rotates along with the drum body 100.

[0203] Among them, a rag 120 is installed on the outside of the drum body 100 to clean the floor. The driving member 200 can be set as a motor, which is easy to control and works stably and reliably. Since the blade 300 can be disassembled relative to the drum body 100, it means that the blade 300 is set as an independent component, which is convenient for processing and subsequent maintenance, reducing processing and subsequent maintenance costs. As long as the blade 300 is within the size range of the installation cavity 110, the design of the blade 300 is not limited by the drum body 100, and thus a blade 300 that better meets the working conditions can be designed and processed. Specifically, the blade 300 can be an axial flow blade.

[0204] When the cleaning assembly 820 of the above embodiment is working, the motor drives the roller body 100 to rotate, and the blades 300 rotate along with the roller body 100. The rotation of the blades 300 drives the air in the installation cavity 110 to flow through the gap between the motor and the inner wall of the installation cavity 110. The flowing air dissipates heat from the motor, lowers the motor temperature, and reduces the occurrence of motor overheating. The cleaning assembly 820 of the above embodiment uses the cleaning assembly 820's own drive member 200 to drive the blades 300 to rotate, thereby improving the heat dissipation effect of the drive member 200 itself. This allows the cleaning assembly 820 to achieve the purpose of improving the heat dissipation effect of the built-in drive member 200 through a simple structure, without significantly increasing the overall cost or the space occupied by the cleaning assembly 820, and is highly practical.

[0205] Among them, the installation cavity 110 is cylindrical as a whole, which is convenient for processing to reduce costs and also convenient for motor installation; the motor and the drum body 100 can be connected by spline plug-in between the output end of the motor and the inner wall of the installation cavity 110, or by interference fit between the output end of the motor and the inner wall of the installation cavity 110, etc.

[0206] Specifically, as shown in Figures 13 to 16, in some embodiments of the present application, the connecting assembly includes a first mounting bracket 410, and the first mounting bracket 410 and the inner side wall of the mounting cavity 110 are fixedly installed in cooperation. The first mounting bracket 410 is fixedly installed using the inner side wall of the mounting cavity 110, which can make full use of the space inside the mounting cavity 110, reduce the connection between the first mounting bracket 410 and other positions of the drum body 100, and avoid affecting the rag 120 on the drum body 100. The blade 300 is installed at the end of the first mounting bracket 410 facing the driving member 200, whereby the blade 300 is located between the driving member 200 and the first mounting bracket 410, reducing the probability of the blade 300 contacting external components, and ensuring the normal operation of the blade 300.

[0207] The first mounting bracket 410, the blades 300 and the drum body 100 are manufactured separately, which can reduce the processing difficulty compared to integral manufacturing. In addition, during the subsequent maintenance process, if the drum body 100, the blades 300 or the first mounting bracket 410 are damaged, only the corresponding parts need to be replaced, and there is no need to replace the entire body, which can reduce the subsequent maintenance cost.

[0208] Specifically, as shown in Figures 13 to 16, in some embodiments of the present application, the first mounting bracket 410 is cylindrical. Specifically, the upper end of the first mounting bracket 410 is open, the lower end has a bottom plate 420, and the side is formed by the side plate. The whole is cylindrical. This structure can effectively reduce the material used in the first mounting bracket 410 and reduce costs.

[0209] The outer sidewall of the first mounting bracket 410, i.e., the exterior of the side plate, is provided with a rib 430 extending axially along the drum body 100. The inner sidewall of the mounting cavity 110 is provided with a retaining groove 130 that engages with the rib 430 and extends axially along the drum body 100. The cylindrical first mounting bracket 410 can extend a certain distance into the mounting cavity 110, thereby providing sufficient insertion travel for the rib 430 to engage with the retaining groove 130, thereby forming a stable connection.

[0210] The structural cooperation between the rib 430 and the limiting groove 130 can limit the rotation of the first mounting bracket 410 relative to the drum body 100. The rib 430 and the limiting groove 130 are interference fit to limit the axial movement of the first mounting bracket 410 relative to the drum body 100.

[0211] Among them, one of the rib 430 and the limiting groove 130 can be set to be wedge-shaped so that the rib 430 and the limiting groove 130 can be smoothly plugged in.

[0212] Of course, it is understood by those skilled in the art that the connection between the first mounting bracket 410 and the drum body 100 is not limited to the above-mentioned embodiment, and other implementations may also be adopted. For example, the first mounting bracket 410 may be provided with an external thread on the outer wall, and an internal thread that cooperates with the external thread may be provided on the inner wall of the mounting cavity 110. The first mounting bracket 410 may be installed on the drum body 100 through the cooperation of the external thread and the internal thread.

[0213] Specifically, there are various ways to mount the blade 300 and the first mounting bracket 410. In some embodiments of the present application, as shown in Figures 5 and 7, a mounting hole 440 is provided on the bottom plate 420 of the first mounting bracket 410, and the blade 300 is secured by a threaded connector 450 that cooperates with the mounting hole 440. In this embodiment, the threaded connector 450 may be a screw, and the mounting hole 440 may be a threaded hole. The screw and the threaded hole cooperate to press the blade 300 tightly, thereby securing the blade 300 to the first mounting bracket 410. The use of screws to secure the blade 300 is simple and quick, and the direction of rotation of the screws when tightening the blade 300 is opposite to the direction of rotation of the blade 300 during operation, which can effectively improve the stability of the blade 300 during operation.

[0214] Before installing the first mounting bracket 410, the blade 300 is first installed on the first mounting bracket 410, and then the first mounting bracket 410 is installed on the drum body 100. Of course, the installation method of the blade 300 and the first mounting bracket 410 is not limited to the above embodiment. Other installation methods can also be used. For example, the blade 300 can be fixed to the first mounting bracket 410 by rivets, which can also achieve the purpose of fixing the blade 300 to the first mounting bracket 410.

[0215] As shown in Figures 13 and 15, in some embodiments of the present application, the driving member 200 is fixedly mounted on the cleaning device 700 through a mounting structure. The mounting structure includes a roller cover 710 and a second mounting bracket 620. The roller cover 710 is fixedly mounted on the cleaning device 700. The second mounting bracket 620 is fixedly mounted on the roller cover 710 by screws. The motor is fixedly mounted on the second mounting bracket 620. The motor is in a horizontally suspended state. The drum body 100 is plugged into the output end of the motor. In order to position the drum body 100 axially, the cleaning component 820 also includes a limiting end cover 500. One end of the limiting end cover 500 extends into the first mounting bracket 410. The limiting end cover 500 of this part is annular. , and a hook portion 510 is formed inwardly at the outer end, and a third bearing 480 is provided between the hook portion 510 and the first mounting bracket 410, thereby the limiting end cover 500 can also provide a certain support for the first mounting bracket 410, and the hook portion 510 is in a suspended state, so it has a certain elasticity, and the elasticity of the hook portion 510 is used to make the hook portion 510 maintain a close fit with the bearing; the other end of the limiting end cover 500 is provided with a limiting portion 520 for blocking the axial movement of the drum body 100, and the outline of the limiting portion 520 is larger than the outline of the opening of the mounting cavity 110 near the limiting end cover 500, so that the limiting portion 520 cannot enter the mounting cavity 110, and then the limiting portion 520 can limit the end of the drum body 100.

[0216] A matching structure is provided on the roller cover 710 corresponding to the limiting end cover 500 to realize that the limiting end cover 500 is detachable relative to the roller cover 710. After the cleaning assembly 820 is installed on the cleaning equipment 700, the limiting end cover 500 is rotated to a predetermined angle, so that the limiting end cover 500 can cooperate with the matching structure on the roller cover 710, thereby forming a preliminary limit for the limiting end cover 500. The limiting end cover 500 forms a limit and support for the roller body 100. When disassembly is required, the limiting end cover 500 can be rotated in the opposite direction until the limiting end cover 500 is separated from the matching structure on the roller cover 710. At this time, the limiting end cover 500 can be taken out.

[0217] In order to facilitate operation, a knob 530 is provided on the limiting end cover 500. The limiting end cover 500 is rotated by rotating the knob 530, so that the user can operate the limiting end cover 500.

[0218] In some embodiments of the present application, a transmission connection is formed between the drum body 100 and the motor by plugging, so the drum body 100 and the motor can be separated in the axial direction. After the limit end cover 500 is removed, the drum body 100 can be separated from the motor in the axial direction to facilitate cleaning or replacement of the drum body 100, which is very convenient.

[0219] As shown in Figures 13 to 16, in some embodiments of the present application, the specific installation method of the third bearing 480 is as follows: the bottom plate 420 of the first mounting bracket 410 is further provided with a connecting rod 460, which is fixedly connected to the threaded connector 450. A portion of the connecting rod 460 is cylindrical, and the third bearing 480 can be installed on the cylindrical portion of the connecting rod 460. In the above-mentioned installation method of the third bearing 480, the threaded connector 450 can be used to both install the blade 300 and fix the connecting rod 460. The structure is simple and practical, and it can also provide stable support for the operation of the third bearing 480.

[0220] It should be noted that in order to further improve the cantilever supporting capacity of the connecting rod 460, a countersunk hole 470 is provided on the bottom plate 420 of the first mounting bracket 410. The bottom of the countersunk hole 470 is connected to the mounting hole 440. At this time, the mounting hole 440 can be a light hole, and the connecting rod 460 is partially inserted into the countersunk hole 470. The countersunk hole 470 is a hole of a non-rotating structure. Therefore, after the connecting rod 460 is inserted into the countersunk hole 470, the structure of the countersunk hole 470 can limit the rotation of the connecting rod 460. The cooperation between the countersunk hole 470 and the connecting rod 460 can, on the one hand, improve the cantilever supporting capacity of the connecting rod 460, and on the other hand, limit the rotation of the connecting rod 460, which is conducive to the installation of the threaded connector 450. The corresponding threaded connector 450 on the connecting rod 460 can be provided with a threaded hole for cooperation.

[0221] It should be noted that the connection between the connecting rod 460 and the first mounting bracket 410 is not limited to the above-mentioned embodiment, and other embodiments can also be adopted. For example, glue can be set between the connecting rod 460 and the countersunk hole 470 to achieve a fixed connection by curing the glue.

[0222] As shown in Figures 13 and 15, in some embodiments of the present application, a fourth bearing 610 is arranged between the second mounting bracket 620 and the inner wall of the mounting cavity 110, and the fourth bearing 610 is used to support the drum body 100; the driving member 200 is installed on the second mounting bracket 620, and the second mounting bracket 620 is fixedly connected to the cleaning equipment 700. The second mounting bracket 620 and the fourth bearing 610 can increase the stability of the drum body 100 during operation.

[0223] To sum up, in some embodiments of the present application, the drum body 100 can obtain sufficient support from the first mounting bracket 410 and the second mounting bracket 620 during normal operation, so that the drum body 100 can operate stably. When the drum needs to be cleaned or replaced, the limiting end cover 500 can be rotated until the limiting end cover 500 is separated from the matching structure on the cleaning device 700, that is, the limiting end cover 500 can be taken out. After the limiting end cover 500 is taken out, the drum body 100 can be directly separated from the motor along the axial direction so that the drum body 100 can be cleaned or replaced.

[0224] It should be noted that after the cleaning component 820 is assembled, the mounting cavity 110 is still connected to the outside air, so that the blades 300 drive the air in the mounting cavity 110 to circulate and exchange with the outside air, providing a better heat dissipation environment for the motor. In order to further improve the heat dissipation efficiency of the motor, an air vent 490 is provided on the bottom plate 420 of the first mounting bracket 410, which penetrates the bottom plate 420. The second mounting bracket 620 has a channel for the wire to pass through, which can also allow air to flow. There is a gap between the first mounting bracket 410 and the limiting end cover 500, which is connected to the air vent 490, thereby connecting the mounting cavity 110 to the outside air. The cross-section of the connecting channel between the outside atmosphere and the mounting cavity 110 is expanded through the air vent 490, thereby increasing the exchange rate between the outside atmosphere and the air in the mounting cavity 110, thereby further improving the heat dissipation efficiency of the motor.

A dirt shield 750 is installed at the lower part of the accommodating cavity. The rag 120 passes through the dirt shield 750 first after cleaning the floor. The dirt shield 750 can reduce the occurrence of the situation where the rag 120 carries garbage that is thrown into the accommodating cavity when it rotates. After passing through the dirt shield 750, the rag 120 Then it contacts the comb plate 740, which further intercepts the garbage carried by the rag 120, reducing the amount of garbage entering the next link. After passing through the comb plate 740, the rag 120 continues to rotate and passes through the water spray assembly 730. The water spray assembly 730 sprays clean water onto the rag 120 to clean the rag 120. Then the rag 120 continues to rotate to the sewage box 720. The sewage box 720 is provided with a wiper rib plate, which is arranged parallel to the rag 120. When the rag 120 passes through the wiper rib plate, it will be squeezed by the wiper rib plate, and the squeezed sewage will enter the sewage box 720. After simple filtration in the sewage box 720, the sewage is finally pumped into the sewage tank for storage.

[0227] The blade 300 is detachably mounted in the mounting cavity 110 via the first mounting bracket 410. The blade 300 is an independent component, which is convenient for processing and subsequent maintenance. As long as the blade 300 is within the size range of the mounting cavity 110, the design of the blade 300 is not restricted by the drum body 100, and the blade 300 can be designed and processed to better meet the working conditions. Specifically, the blade 300 can be an axial flow blade.

[0228] When the cleaning device 700 of the above embodiment is working, the motor drives the drum body 100 to rotate, and the blades 300 rotate along with the drum body 100. The rotation of the blades 300 drives the air in the installation cavity 110 to flow through the gap between the motor and the inner wall of the installation cavity 110. The flowing air dissipates heat from the motor, lowers the motor temperature, and reduces the occurrence of motor overheating. The cleaning component 820 of the above embodiment uses the cleaning component 820's own drive member 200 to drive the blades 300 to rotate, thereby improving the heat dissipation effect of the drive member 200 itself, so that the cleaning component 820 can achieve the purpose of improving the heat dissipation effect of the built-in drive member 200 through a simple structure, and the overall cost does not increase significantly, and the space occupied by the cleaning component 820 does not increase significantly, which is highly practical.

[0229] As shown in Figures 13 to 16, in some embodiments of the present application, the connecting assembly includes a first mounting bracket 410, and the first mounting bracket 410 and the inner side wall of the mounting cavity 110 are fixedly installed in cooperation. The first mounting bracket 410 is fixedly installed using the inner side wall of the mounting cavity 110, which can fully utilize the space inside the mounting cavity 110, reduce the connection between the first mounting bracket 410 and other positions of the drum body 100, and avoid affecting the rag 120 on the drum body 100. The blade 300 is installed at the end of the first mounting bracket 410 facing the driving member 200, whereby the blade 300 is located between the driving member 200 and the first mounting bracket 410, reducing the probability of the blade 300 contacting external components, and ensuring the normal operation of the blade 300.

[0230] Specifically, as shown in Figures 13 to 16, in some embodiments of the present application, the first mounting bracket 410 is cylindrical. Specifically, the upper end of the first mounting bracket 410 is open, the lower end has a bottom plate 420, and the side is formed by the side plate. The whole is cylindrical. This structure can effectively reduce the material used in the first mounting bracket 410 and reduce costs.

[0231] The outer sidewall of the first mounting bracket 410, i.e., the exterior of the side plate, is provided with a rib 430 extending axially along the drum body 100. The inner sidewall of the mounting cavity 110 is provided with a retaining groove 130 that engages with the rib 430 and extends axially along the drum body 100. The cylindrical first mounting bracket 410 can extend a certain distance into the mounting cavity 110, thereby providing sufficient insertion travel for the rib 430 to engage with the retaining groove 130, thereby forming a stable connection.

[0232] The structural cooperation between the rib 430 and the limiting groove 130 can limit the rotation of the first mounting bracket 410 relative to the drum body 100. The rib 430 and the limiting groove 130 are interference fit to limit the axial movement of the first mounting bracket 410 relative to the drum body 100.

[0233] In some embodiments of the present application, as shown in Figures 15 and 17, a mounting hole 440 is provided on the bottom plate 420 of the first mounting bracket 410, and the blade 300 is secured via a threaded connector 450 that cooperates with the mounting hole 440. In this embodiment, the threaded connector 450 may be a screw, and the mounting hole 440 may be a threaded hole. The screw and the threaded hole cooperate to press the blade 300, thereby securing the blade 300 to the first mounting bracket 410. The use of screws to secure the blade 300 is a simple and quick installation method. The direction of rotation of the screws to secure the blade 300 is opposite to the direction of rotation of the blade 300 during operation, which can effectively improve the operational stability of the blade 300.

[0234] To sum up, in some embodiments of the present application, the drum body 100 can obtain sufficient support from the first mounting bracket 410 and the second mounting bracket 620 during normal operation, so that the drum body 100 can operate stably. When the drum needs to be cleaned or replaced, the limiting end cover 500 can be rotated until the limiting end cover 500 is separated from the matching structure on the cleaning device 700, that is, the limiting end cover 500 can be taken out. After the limiting end cover 500 is taken out, the drum body 100 can be directly separated from the motor along the axial direction so that the drum body 100 can be cleaned or replaced.
