Description

Technical Field

[0001] The present invention relates to the technical field of cleaning appliances, and particularly to a floor brush and a vacuum cleaner. Background Art

[0002] With the improvement of people's living standards, wet and dry vacuum cleaners are gradually favored by more and more users because of their small size, light weight, convenient cleaning, and wide range of applicable places.

[0003] Common wet and dry vacuum cleaners usually consist of a floor brush, a main body, and a suction pipe. The suction pipe is connected between the main body and the floor brush. The floor brush includes a mopping component, which is usually a structure like a floor wiper or a tracked roller structure, etc. The contact area with the ground is large, and the ground can be cleaned quickly and efficiently. However, this type of mopping component needs to be disassembled for cleaning, which is not convenient and hygienic. Summary of the Invention

[0004] The present invention provides a floor brush and a vacuum cleaner, which are relatively flexible and convenient to operate, have a high cleaning efficiency and a good cleaning effect, and the cleaning component is more convenient to clean.

[0005] On the one hand, the present invention provides a floor brush, which includes a hollow housing and a cleaning component. The housing has a receiving groove with an opening at the bottom of the housing. The cleaning component is received in the receiving groove, and the front end of the housing has a suction port;

[0006] The cleaning component includes an annular cleaning belt and two rotating shafts surrounded by the cleaning belt. The two rotating shafts are arranged side by side and spaced apart to support on the inner circumferential surface of the cleaning belt and drive the cleaning belt to rotate. The outer circumferential surface of the cleaning belt forms a moving cleaning surface.

[0007] The floor brush provided by the present invention is composed of a housing and a cleaning component. The housing is hollow inside and the outer surface of the bottom forms a receiving groove. The cleaning component is installed in the receiving groove. By making the receiving groove have an opening, and the opening is located at the bottom of the housing, the cleaning component can contact the ground through the opening to clean the ground; the cleaning component specifically includes a cleaning belt and two rotating shafts. The cleaning belt is annular and sleeved outside the two rotating shafts, and the two rotating shafts are arranged side by side and spaced apart. The two rotating shafts can drive the cleaning belt outside them to rotate synchronously, so that the outer circumferential surface of the cleaning belt forms a movable cleaning surface. Specifically, the part of the cleaning belt between the two rotating shafts contacts the ground to form a cleaning surface. On the one hand, the cleaning surface formed by the cleaning belt moves in contact with the ground, so the cleaning effect is good. On the other hand, since there is a gap between the two rotating shafts, the cleaning surface and the ground are in planar contact, and the contact area is large, so the cleaning efficiency is high.

[0008] Optionally, the floor brush further includes a dust suction air duct located inside the housing. The shape of the dust suction air duct matches the contour of the cleaning assembly. The air inlet end of the dust suction air duct communicates with the dust suction port, and the air outlet end of the dust suction air duct extends to the rear end of the floor brush. The dust suction air duct can be part of the dust suction assembly or other components, used to connect the dust suction port and other components. Since the shape of the dust suction air duct matches the outer contour of the cleaning assembly, setting the dust suction air duct inside the floor brush will not affect the overall shape of the floor brush, making the structure of the floor brush relatively compact.

[0009] Optionally, at least part of the structure of the dust suction air duct is located above the cleaning assembly. In this way, the dust suction air duct can extend to the rear of the cleaning assembly to convey dust to other components, and at the same time, the dust suction air duct will not affect the cleaning operation of the cleaning assembly.

[0010] Optionally, the dust suction air duct includes a first air duct and a second air duct arranged in sequence along the air inlet direction. The first air duct and the second air duct are connected by a bending section, and the height where the first air duct is located is higher than the height where the second air duct is located. On the one hand, this can be adapted to the shape of the cleaning assembly and the floor brush, making the structure of the floor brush relatively compact; on the other hand, when dust backflows, the backflow dust will be blocked at the stepped bending section between the first air duct and the second air duct. Therefore, this structure can prevent the backflow of dust, avoid the influence caused by dust backflow, and ensure the cleaning effect of the vacuum cleaner.

[0011] Optionally, the cleaning assembly can rotate around one of the rotation axes so that the cleaning assembly extends out from the opening.

[0012] By rotating the cleaning assembly around one of the rotation axes, the cleaning assembly can extend out of the housing from the opening, which is convenient for cleaning the cleaning assembly and for disassembling and replacing the cleaning assembly.

[0013] Optionally, the two rotation axes are respectively located at both ends of the cleaning assembly; the cleaning assembly can rotate around one of the rotation axes so that the other end of the cleaning assembly extends out from the opening.

[0014] By arranging the two rotation axes at both ends of the cleaning assembly respectively, when the cleaning assembly rotates around one of the rotation axes, one end of the cleaning assembly corresponding to this rotation axis is located inside the housing, while the other end of the cleaning assembly corresponding to the other rotation axis extends out from the opening.

[0015] Optionally, the two rotation axes include a driving shaft and a driven shaft. The driving shaft is used to drive the cleaning belt to rotate, and the driven shaft rotates under the drive of the cleaning belt;

[0016] The cleaning assembly can rotate around the driving shaft so that one end of the cleaning assembly corresponding to the driven shaft extends out from the opening.

[0017] By making one of the two rotating shafts the driving shaft and the other the driven shaft, the rotation of the driving shaft can drive the cleaning belt to rotate, and the rotation of the cleaning belt can drive the driven shaft to rotate, so that the driving shaft and the driven shaft can rotate synchronously to make the cleaning belt rotate stably.

[0018] Optionally, the axes of the two rotating shafts are both in the horizontal direction, and the end of the cleaning assembly can extend from the opening to below the housing.

[0019] By making the axes of the two rotating shafts both in the horizontal direction, the two rotating shafts can be located in the same horizontal plane, and the horizontal plane between the two rotating shafts forms a cleaning surface in contact with the ground, which can improve the cleaning efficiency of the cleaning assembly; and the other end of the cleaning assembly can extend out of the housing to facilitate the cleaning of the cleaning assembly.

[0020] Optionally, when the end of the cleaning assembly extends out of the opening, the angle range of the cleaning assembly rotating around the rotating shaft is between 0° and 95°.

[0021] By making the angle range of the cleaning assembly rotating around the rotating shaft between 0° and 95°, the extended part of the cleaning assembly can be located within a suitable range, which can facilitate the cleaning of the cleaning assembly while not increasing the volume of the receiving groove.

[0022] Optionally, the cleaning assembly further includes a bracket, and the rotating shaft is arranged on the bracket.

[0023] By arranging a bracket in the cleaning assembly, the two rotating shafts can be arranged on the bracket so that the cleaning assembly forms an integral body, and the two rotating shafts can be arranged in parallel at intervals.

[0024] Optionally, the floor brush further includes a driving unit, and the driving unit is connected to at least one rotating shaft and is used to drive the rotating shaft to rotate.

[0025] By arranging a driving unit on the floor brush and connecting the driving unit to the rotating shaft, the driving unit can drive the rotating shaft to rotate, and the rotation of the rotating shaft can drive the cleaning belt to rotate so that the cleaning assembly can move to contact the ground.

[0026] Optionally, the floor brush further includes a water tank, and the water tank is arranged on the housing.

[0027] By arranging a water tank on the floor brush, the water tank can provide cleaning water for the cleaning assembly, and by arranging the water tank on the housing, it is convenient for the installation and removal of the water tank.

[0028] Optionally, the driving unit and the water tank are respectively arranged on both sides of the central axis of the housing.

[0029] By arranging the driving unit and the water tank on both sides of the central axis of the housing respectively, the layout of the driving unit and the water tank can be made more reasonable, the space occupied by both can be reduced, and the connection between the driving unit and the water tank can be facilitated.

[0030] Optionally, an installation groove is formed at the top of the housing, and the shape of the installation groove matches the shape of the water tank. The water tank is arranged in the installation groove. Among them, a water supply port is formed on the groove wall of the installation groove, and the water supply port is communicated with the accommodating groove.

[0031] By forming an installation groove at the top of the housing and making the shape of the installation groove match the shape of the water tank, the water tank can be installed in the installation groove. Moreover, by forming a water supply port on the groove wall of the installation groove and communicating the water supply port with the accommodating groove, the cleaning water in the water tank can be delivered to the cleaning assembly through the water supply port.

[0032] Optionally, at least part of the bottom of the installation groove is located above the cleaning assembly, and the shape of the area of the bottom of the groove located above the cleaning assembly matches the shape of the cleaning assembly.

[0033] By making at least part of the installation groove located above the cleaning assembly, the extra space of the housing occupied by the installation groove can be reduced. By making the shape of the area of the bottom of the installation groove located above the cleaning assembly match the cleaning assembly, the bottom of the installation groove at the top of the housing corresponds to the bottom of the accommodating groove at the bottom of the housing.

[0034] Optionally, the top surface of the water tank is flush with the top of the housing.

[0035] By making the top surface of the water tank flush with the top of the housing, the top surface of the water tank and the housing are in the same horizontal plane, which can make the appearance of the housing more simple and generous.

[0036] Optionally, the cleaning belt includes an annular base belt and cleaning members arranged on the outer surface of the base belt. The part of the cleaning members rotating between the two rotating shafts forms a cleaning surface.

[0037] The cleaning belt includes a base belt and cleaning members. The base belt is annular and sleeved on the outer surface of the rotating shaft. The cleaning members are arranged outside the base belt. The cleaning members and the base belt are relatively fixed. The rotating shaft drives the base belt and the cleaning members to rotate. The cleaning members are in rotational contact with the ground. Among them, during the rotation of the cleaning members, the part located between the two rotating shafts can form a cleaning surface in contact with the ground. In this way, the formed cleaning surface has a larger contact area with the ground, and the cleaning surface is in a rotating state relative to the ground. The cleaning efficiency of the cleaning assembly for the ground is higher, and the cleaning effect is better.

[0038] Optionally, the two ends of the cleaning members are spliced with each other to surround the outside of the base belt, and an included angle is formed between the splicing line formed by the cleaning members and the axis of the rotating shaft.

[0039] By arranging the cleaning member in a form where its two ends are spliced together to surround the outside of the baseband, the splicing line can be extended, and there is an included angle between the splicing line and the axis of the rotating shaft. In this way, the splicing line has good contact with the ground, which can improve the cleaning effect of the cleaning member.

[0040] Optionally, the cleaning member is in the shape of a parallelogram in the unfolded state.

[0041] By making the shape of the cleaning member in the unfolded state be a parallelogram, and the parallelogram-shaped cleaning member is spirally wound around the outer surface of the baseband, the splicing line can be in the form of a spiral line, which is relatively long and has good contact with the ground.

[0042] Optionally, the rotating shaft includes a core shaft and a buffer layer located outside the core shaft, and the buffer layer is wrapped around the outer circumferential surface of the core shaft.

[0043] By making the rotating shaft include a core shaft and a buffer layer, and the buffer layer is sleeved outside the core shaft, the buffer layer and the core shaft are relatively fixed. The rotation of the core shaft drives the rotation of the buffer layer, and the baseband is sleeved outside the buffer layer. The friction between the buffer layer and the baseband can drive the stable rotation of the baseband.

[0044] Optionally, a water spraying assembly is arranged in the housing, and the water spraying assembly is communicated with the water tank through a water supply port; wherein, the water spraying assembly is located above the cleaning assembly, and the water outlet side of the water spraying assembly faces the cleaning assembly.

[0045] By arranging a water spraying assembly in the housing, and the water spraying assembly is communicated with the water tank through a water supply port, the cleaning water in the water tank can be conveyed to the water spraying assembly. The water spraying assembly is arranged above the mop and its water outlet side faces the cleaning assembly, so that the water spraying assembly can spray water on the cleaning assembly.

[0046] Optionally, an air duct is also arranged in the housing, and the air duct is located above the cleaning assembly. The inlet of the air duct is communicated with the dust suction port, and the outlet of the air duct faces the rear end of the floor brush.

[0047] By arranging an air duct in the housing of the floor brush, the inlet of the air duct is communicated with the dust suction port, and the outlet of the air duct faces the rear end of the floor brush. The air duct can be communicated with the dust suction assembly located at the rear end of the floor brush, so that the air and dust sucked in by the dust suction port can enter the dust suction assembly through the air duct; by arranging the air duct above the cleaning assembly, the layout of the floor brush is more reasonable.

[0048] Optionally, walking wheels are installed at the bottom of the housing.

[0049] By installing walking wheels at the bottom of the housing, the walking wheels can make the floor brush easier to move, improving the flexibility and portability of the floor brush during use.

[0050] On the other hand, the present invention provides a vacuum cleaner, including a dust suction assembly and the floor brush as described above, and the air ducts in the dust suction assembly and the floor brush are communicated.

[0051] The vacuum cleaner provided by the present invention includes a floor brush and a dust collection assembly. The dust collection assembly may include a vacuum cleaner body and a connecting pipe. One end of the connecting pipe is communicated with the air duct of the floor brush, and the other end of the connecting pipe is communicated with the vacuum cleaner body. Among them, the floor brush is composed of a housing and a cleaning assembly. The inside of the housing is hollow, and a receiving groove is formed on the outer surface of the bottom. The cleaning assembly is installed in the receiving groove. By making the receiving groove have an opening, and the opening is located at the bottom of the housing, the cleaning assembly can contact the ground through the opening to clean the ground. Specifically, the cleaning assembly includes a cleaning belt and two rotating shafts. The cleaning belt is annular and sleeved outside the two rotating shafts, and the two rotating shafts are arranged side by side at intervals. The two rotating shafts can drive the cleaning belt outside them to rotate synchronously, so that the outer circumferential surface of the cleaning belt forms a movable cleaning surface. Specifically, the part of the cleaning belt between the two rotating shafts contacts the ground to form a cleaning surface. On the one hand, the cleaning surface formed by the cleaning belt moves in contact with the ground, so the cleaning effect is better. On the other hand, since there is an interval between the two rotating shafts, the cleaning surface and the ground are in planar contact, and the contact area is large, so the cleaning efficiency is high.

[0052] Optionally, the vacuum cleaner further includes a cleaning base. A receiving groove is formed at the top of the cleaning base. The receiving groove includes a receiving cavity and a first supporting portion surrounding the receiving cavity. Among them, the bottom of the housing is supported on the first supporting portion, and the part of the cleaning assembly extending below the housing is located in the receiving cavity.

[0053] The vacuum cleaner further includes a cleaning base for cleaning the cleaning assembly. By forming a receiving groove at the top of the cleaning base, the bottom of the floor brush can correspond to the receiving groove. The receiving groove includes a receiving cavity and a first supporting portion. The part of the cleaning assembly extending outside the housing can be accommodated in the receiving groove, and the first supporting portion surrounds the outside of the receiving groove, so that the bottom of the housing can be supported on the first supporting portion.

[0054] Optionally, the receiving cavity includes a bottom surface and a side surface. The side surface faces the cleaning surface of the cleaning assembly, and the side surface is an inclined surface inclined relative to the bottom surface. The inclination angle of the side surface relative to the bottom surface is between 0° and 90°.

[0055] The receiving cavity has a bottom surface and a side surface. The lowermost end of the part of the cleaning assembly extending outside the housing corresponds to the ground, and the cleaning surface of the cleaning assembly between the two rotating shafts corresponds to the side surface. By making the side surface an inclined surface inclined relative to the bottom surface, while satisfying the accommodation of the extending part of the cleaning assembly, the volume of the receiving cavity can be reduced.

[0056] Optionally, the receiving cavity further includes side walls at both ends in the length direction of the receiving cavity. The side walls have second supporting portions. The second supporting portions have supporting surfaces. The edges of the cleaning assembly are supported on the supporting surfaces, and the inclination angle of the supporting surface relative to the bottom surface is between 30° and 60°.

[0057] The two ends of the accommodating cavity along its length direction also have side walls. By making the side walls have second supporting parts, the bottom end of the protruding part of the cleaning assembly can be supported on the second supporting parts, and by making the second supporting parts higher than the bottom surface, there can be a gap between the bottom end of the cleaning assembly and the bottom surface of the accommodating cavity, which can prevent the cleaning assembly from being worn by the bottom surface of the accommodating cavity.

[0058] The second supporting part has a supporting surface that fits the cleaning surface of the cleaning assembly. By making the supporting surface inclined relative to the bottom surface, the cleaning assembly can be inclined relative to the ground, which can reduce the height of the accommodating cavity and the overall height of the cleaning base.

[0087] As Figures 1 to 15 shown, this embodiment provides a floor brush 1, which includes a hollow housing 11 and a cleaning assembly 12. The housing 11 has a receiving groove 13, and the receiving groove 13 has an opening at the bottom of the housing 11. The cleaning assembly 12 is received in the receiving groove 13, and the front end of the housing 11 has a dust suction port 111; the cleaning assembly 12 includes an annular cleaning belt 121 and two rotating shafts 122 surrounded by the cleaning belt 121. The two rotating shafts 122 are arranged side by side and at intervals to support on the inner circumferential surface of the cleaning belt 121 and drive the cleaning belt 121 to rotate. The outer circumferential surface of the cleaning belt 121 forms a moving cleaning surface 124.

[0088] As Figures 1 to 9 shown, the floor brush 1 provided in this embodiment is mainly composed of a housing 11 and a cleaning assembly 12. The housing 11 is a hollow structure. The bottom of the housing 11, that is, the outer surface of the side of the housing 11 facing the ground, forms a receiving groove 13. The receiving groove 13 is in an open form, that is, the receiving groove 13 has an opening facing the ground. The cleaning assembly 12 is installed in the receiving groove 13. Among them, the cleaning assembly 12 extends into and is fixed in the receiving groove 13 through this opening, and through this opening, the surface of the cleaning assembly 12 facing the ground can be directly in contact with the ground, so that the cleaning assembly 12 can clean the ground.

[0089] Among them, the cleaning assembly 12 includes a cleaning belt 121 and a rotating shaft 122. There are two rotating shafts 122. The two rotating shafts 122 are arranged side by side and at intervals. The cleaning belt 121 is an annular cleaning belt 121. The annular cleaning belt 121 surrounds the outside of the two rotating shafts 122. The rotating shaft 122 is a transmission member, and the rotation of the rotating shaft 122 drives the cleaning belt 121 outside it to rotate.

[0090] The rotation of the rotating shaft 122 drives the cleaning belt 121 to rotate synchronously. The cleaning belt 121 is in rotational contact with the ground, and the generated frictional force is relatively large, which can improve the cleaning effect of the cleaning assembly 12 on the ground. Moreover, by arranging two rotating shafts 122 side by side with a spacing therebetween, and the cleaning belt 121 is sleeved outside the two rotating shafts 122. The cleaning belt 121 not only covers the outside of the two rotating shafts 122, but also covers the space between the two rotating shafts 122, so that the coverage area of the cleaning belt 121 is relatively large.

[0091] During the operation of the cleaning assembly 12, the two rotating shafts 122 rotate synchronously, and the part of the cleaning belt 121 between the two rotating shafts 122 contacts the ground, and this part of the cleaning belt 121 forms a cleaning surface 124. Since the rotating shaft 122 is in a continuous rotation process, the part of the cleaning belt 121 between the two rotating shafts 122 is also continuously rotating, so that this part of the cleaning belt 121 can form a cleaning surface 124. In this way, not only is the contact area between the cleaning surface 124 and the ground relatively large, but also the cleaning surface 124 is in moving contact with the ground, so that the cleaning assembly 12 can have a relatively high cleaning efficiency and a good cleaning effect at the same time.

[0092] In addition, in this embodiment, two rotating shafts 122 are provided, and the cleaning belt 121 is sleeved outside the two rotating shafts 122. The two rotating shafts 122 drive the cleaning belt 121 to rotate synchronously, which can make the base belt 1211 rotate more smoothly. Moreover, the cleaning belt 121 is supported by the two rotating shafts 122, so that the supporting effect on the cleaning belt 121 is better, and the overall structural strength of the cleaning assembly 12 can be ensured.

[0093] Therefore, in this embodiment, by arranging two rotating shafts 122 spaced side by side and sleeving an annular cleaning belt 121 outside the rotating shafts 122, the cleaning assembly 12 can have better strength and good working stability. More importantly, the contact area between the cleaning belt 121 and the ground is relatively large, and the cleaning belt 121 is in moving contact with the ground, and the frictional force between the cleaning belt 121 and the ground is relatively large, so that the cleaning efficiency of the cleaning assembly 12 can be improved while ensuring that the cleaning assembly 12 has a good cleaning effect.

[0094] In addition, as Figure 2 、 Figure 6 and Figure 8As shown in the figure, a dust suction port 111 is further provided at the front end of the housing 11 of the floor brush 1. The dust suction port 111 can correspond to the front of the floor to be cleaned. In this way, air and dust in the air can be inhaled through the dust suction port 111, so that the floor brush 1 has the function of dust suction. Among them, by arranging the dust suction port 111 at the front end of the housing 11 and the cleaning assembly 12 is correspondingly located behind the dust suction port 111. When the floor brush 1 is working, the dust on the floor to be cleaned is first sucked through the dust suction port 111, and then the floor to be cleaned is further cleaned through the friction between the cleaning assembly 12 and the floor. In this way, the cleaning effect of the floor brush 1 on the floor is more thorough. As Figures 1 to 3 shown, there can be multiple dust suction ports 111, and they are arranged at intervals in the horizontal direction at the front end of the housing 11. By arranging multiple dust suction ports 111 at the front end of the housing 11 and the multiple dust suction ports 111 are arranged at intervals in the horizontal direction, the amount of air inhaled by the multiple dust suction ports 111 is larger, the dust suction efficiency of the dust suction port 111 is higher, and because the multiple dust suction ports 111 are arranged horizontally at intervals, the overall area occupied by the dust suction ports 111 is larger. Therefore, the absorption amount of dust and other foreign matters at the front end of the floor brush 1 can be further increased, thereby improving the dust suction efficiency of the vacuum cleaner.

[0095] As Figures 1 to 3 shown, in a possible implementation manner, the front end of the housing 11 further has a plurality of drainage grooves 115 that are recessed into the interior of the housing 11. The first end of the drainage groove 115 faces the front end of the housing 11, and the second end of the drainage groove 115 is in one-to-one correspondence and communication with the dust suction port 111; the notch of the drainage groove 115 gradually increases in the direction from the second end to the first end of the drainage groove 115.

[0096] By arranging the drainage grooves 115 at the front end of the housing 11, the drainage grooves 115 are recessed from the front end of the housing 11 towards the interior of the housing 11. Specifically, the first end of the drainage groove 115 faces the front end of the housing 11, and the second end of the drainage groove 115 extends to the dust suction port 111 and is in one-to-one correspondence and communication with the dust suction port 111. In this way, dust and other foreign matters in the air can enter the dust suction port 111 through the drainage grooves 115.

[0097] Among them, the notch of the drainage groove 115 gradually decreases from its first end to the second end. This setting method is to set the shape of the drainage groove 115 as a trumpet shape with the large-diameter end facing the front end of the floor brush 1, so as to effectively increase the storage amount of dust and other impurities at the front end of the floor brush 1, so that more dust and other sundries enter the vacuum cleaner through the drainage groove 115, thereby improving the dust suction efficiency of the floor brush 1 in this embodiment. In addition, the large diameter of the drainage groove 115 faces the front end, which also facilitates large particles to enter the drainage groove 115, improving the cleaning effect of the floor brush 1 on large particle sundries in this embodiment.

[0098] As Figure 3 and Figure 16As shown, in order to convey the dust sucked by the dust suction port 111 to other positions of the floor brush 1. As an alternative, the floor brush 1 further includes a dust suction air duct 113. The dust suction air duct 113 is arranged inside the housing 11, and the shape of the dust suction air duct 113 matches the outer contour of the cleaning assembly 12. The air inlet end of the dust suction air duct 113 is communicated with the dust suction port 111, and the air outlet end extends to the rear end part of the floor brush 1. In this way, the dust sucked by the dust suction port 111 can be conveyed to other components through the dust suction air duct 113, thereby completing the dust suction operation.

[0099] Among them, the dust suction air duct 113 can be a part of the dust suction assembly or other components, and is used to connect the dust suction port 111 and other components. Since the shape of the dust suction air duct 113 matches the outer contour of the cleaning assembly 12, arranging the dust suction air duct 113 inside the floor brush 1 will not affect the overall shape of the floor brush 1, making the structure of the floor brush 1 relatively compact.

[0100] As Figure 3 shown, in an alternative, at least part of the structure of the dust suction air duct 113 is located above the cleaning assembly 12. At this time, the bottom area of the cleaning assembly 12 is used to perform the cleaning operation, and the dust suction air duct 113 can pass above the cleaning assembly 12 and run through the length direction of the floor brush 1 until it extends to the rear side part of the floor brush 1. In this way, the dust suction air duct 113 can extend to the rear of the cleaning assembly 12 to convey the dust to other components, and at the same time, the dust suction air duct 113 will not affect the cleaning operation of the cleaning assembly. Specifically, the overall extending direction of the dust suction air duct 113 can be along the length direction of the cleaning assembly 12.

[0101] Among them, as Figure 16 shown, optionally, the dust suction air duct 113 includes a first air duct 1131 and a second air duct 1132 arranged in sequence along the air inlet direction. The first air duct 1131 and the second air duct 1132 are connected by a bending section 1133, and the height where the first air duct 1131 is located is higher than the height where the second air duct 1132 is located.

[0102] Specifically, the first air duct 1131 and the second air duct 1132 are arranged in sequence along the air inlet direction of the dust suction air duct 113. After the dusty air enters the dust suction air duct 113, it first passes through the first air duct 1131 and then flows into the second air duct 1132. Among them, the height where the first air duct 1131 is located is higher than the height where the second air duct 1132 is located, that is, the position of the first air duct 1131 is above the second air duct 1132. The dusty air flows smoothly in the first air duct 1131. When the dusty air flows from the first air duct 1131 into the second air duct 1132, the dusty air needs to move downward from the first air duct 1131 to enter the second air duct 1132. At the same time, the bent section 1133 between the first air duct 1131 and the second air duct 1132 forms a stepped structure between the first air duct 1131 and the second air duct 1132. It can be understood that the second air duct 1132 is at the position of the lower step compared to the first air duct 1131. In this way, the dust suction air duct 113 is formed with the first air duct 1131 and the second air duct 1132 as described above. On the one hand, it can be adapted to the shapes of the cleaning component 12 and the floor brush 1; on the other hand, when dust backflows occur, the backflow dust will be blocked at the stepped bent section 1133 formed between the first air duct 1131 and the second air duct. Therefore, this structure can prevent the backflow of dust, avoid the influence caused by dust backflow, and ensure the cleaning effect of the vacuum cleaner.

[0103] Among them, optionally, the total width of the suction port 11 can be greater than the width of the dust suction air duct 113. Exemplarily, the total width of the suction port 11 can be greater than 5 times that of the first air duct 1131, so that the suction port 11 has a larger dust suction range. At this time, correspondingly, the air inlet end of the first air duct 1131, that is, the part connected to the suction port 11, can be a trumpet-shaped structure that contracts along the air inlet direction. In order to facilitate the arrangement of the dust suction air duct, the dust suction air duct 113 can be located at or near the central axis of the length direction of the housing 11 of the floor brush 1. In a possible implementation manner, the cleaning component 12 can rotate around one of the rotating shafts 122 so that the cleaning component 12 extends out from the opening. As Figures 7 to 9 shown, in this embodiment, the cleaning component 12 can rotate around one of the two rotating shafts 122. Since the cleaning component 12 is located in the receiving groove 13 of the housing 11, when the cleaning component 12 rotates around one rotating shaft 122, one end of the cleaning component 12 located at this rotating shaft 122 is relatively fixed to the receiving groove 13, that is, one end of the cleaning component 12 still remains in the receiving groove 13, while the end of the cleaning component 12 located at the other rotating shaft 122 can move around this rotating shaft 122 towards or away from the receiving groove 13. Since the receiving groove 13 has an opening on one side of the bottom of the housing 11, the other end of the cleaning component 12 can extend out from the opening of the housing 11.

[0104] By enabling the cleaning component 12 to rotate around one of the rotating shafts 122, when installing the cleaning component 12, one end of the cleaning component 12 located at the rotating shaft 122 can be first fixed in the receiving groove 13, and then the other end of the cleaning component 12 can be rotated to move it towards the receiving groove 13, so that the other end of the cleaning component 12 is also fixed in the receiving groove 13; the disassembly process of the cleaning component 12 can be opposite to the installation process, which will not be elaborated here. This facilitates the installation and disassembly of the cleaning component 12, and further makes the cleaning and replacement of the cleaning component 12 more convenient.

[0105] Specifically, as Figure 5 and Figure 9 shown, the two rotating shafts 122 can be respectively located at both ends of the cleaning component 12; the cleaning component 12 can rotate around one of the rotating shafts 122 so that the other end of the cleaning component 12 extends out from the opening. For the case where the cleaning component 12 rotates relative to the housing 11 of the ground brush 1 and extends out from the opening of the receiving groove 13, as described above, the two rotating shafts 122 are respectively located at both ends of the cleaning component 12. By enabling the cleaning component 12 to rotate around one of the rotating shafts 122, that is, the cleaning component 12 rotates around one of its ends, one end of the cleaning component 12 can be located in the receiving groove 13, and this end of the cleaning component 12 is fixed relative to the receiving groove 13, while the other end of the cleaning component 12 can move towards or away from the receiving groove 13 around the opposite end. Moreover, during the process of the other end of the cleaning component 12 rotating around the opposite end, the other end of the cleaning component 12 can extend out from the opening of the receiving groove 13 to the outside of the housing 11.

[0106] In a possible implementation manner, the two rotating shafts 122 can include a driving shaft 1221 and a driven shaft 1222. The driving shaft 1221 is used to drive the cleaning belt 121 to rotate, and the driven shaft 1222 rotates under the drive of the cleaning belt 121; the cleaning component 12 can rotate around the driving shaft 1221 so that one end of the cleaning component 12 corresponding to the driven shaft 1222 extends out from the opening.

[0107] As Figure 9 shown, in this embodiment, among the two rotating shafts 122 arranged side by side at intervals, one of them is the driving shaft 1221 and the other is the driven shaft 1222. The rotation of the driving shaft 1221 drives the cleaning belt 121 sleeved on its outer surface to rotate. Since the driven shaft 1222 also abuts against the inner surface of the cleaning belt 121, the rotation of the cleaning belt 121 can drive the driven shaft 1222 to rotate. In this way, the driving shaft 1221 and the driven shaft 1222 rotate synchronously, which can ensure the stable rotation of the cleaning belt 121 sleeved on the outer surfaces of both of them.

[0108] Among them, the driving shaft 1221 and the driven shaft 1222 are arranged side by side at both ends of the cleaning assembly 12 at intervals, and the cleaning assembly 12 rotates around the driving shaft 1221. In this way, one end of the cleaning assembly 12 located at the driving shaft 1221 is fixed relative to the receiving groove 13, while one end of the cleaning assembly 12 located at the driven shaft 1222 can move toward or away from the receiving groove 13 around the driving shaft 1221. During the movement of one end of the cleaning assembly 12 located at the driven shaft 1222, the corresponding end of the cleaning assembly 12 to the driven shaft 1222 can extend out from the opening of the receiving groove 13, that is, the whole cleaning assembly 12 is inclined relative to the receiving groove 13, and at least one end of the cleaning assembly 12 corresponding to the driven shaft 1222 can extend out of the housing 11.

[0109] It can be understood that when one end of the cleaning assembly 12 corresponding to the driven shaft 1222 extends out of the housing 11, one end of the cleaning assembly 12 corresponding to the driving shaft 1221 is still located in the receiving groove 13 of the housing 11. The driving shaft 1221 can still rotate, and the rotation of the driving shaft 1221 can drive the cleaning belt 121 to rotate. The rotation of the cleaning belt 121 drives the driven shaft 1222 to rotate. In this way, the whole cleaning assembly 12 can continue to rotate. When the cleaning assembly 12 is cleaned, the part of the cleaning assembly 12 exposed outside the housing 11, that is, the part of the cleaning assembly 12 corresponding to the driven shaft 1222, can contact the cleaning liquid for cleaning the cleaning assembly 12. Since the cleaning assembly 12 is in a continuous rotation process, the cleaning surface 124 of the cleaning belt 121 moves around the two rotating shafts 122. During the rotation, all parts of the cleaning belt 121 will contact the cleaning liquid, so the cleaning assembly 12 can be cleaned comprehensively, and a better cleaning effect of the cleaning assembly 12 can be ensured.

[0110] Among them, as Figure 5 and Figure 9 shown, the axes of the two rotating shafts 122 can both be along the horizontal direction, and the end of the cleaning assembly 12 can extend out from the opening to the lower part of the housing 11. By making the axes of the two rotating shafts 122, namely the driving shaft 1221 and the driven shaft 1222, both along the horizontal direction, the two rotating shafts 122 can be located in the same horizontal plane. In this way, during the operation of the floor brush 1, the horizontal plane where the two rotating shafts 122 are located is parallel to the ground, and the horizontal plane between the two rotating shafts 122 forms a cleaning surface 124 in contact with the ground. In this way, the cleaning surface 124 of the cleaning belt 121 sleeved outside the two rotating shafts 122 is in contact with the ground plane, that is, the cleaning belt 121 has a large contact area with the ground, so the cleaning efficiency of the cleaning assembly 12 can be improved.

[0111] Moreover, after one end of the corresponding driven shaft 1222 of the cleaning assembly 12 extends out of the opening of the accommodation bin to the lower part of the housing 11, the plane where the two rotating shafts 122 are located is inclined relative to the plane where the opening is located, and a part of the driven shaft 1222 of the cleaning assembly 12 is exposed outside the housing 11. The cleaning assembly 12 exposed to the outside of the housing 11 can be immersed in the cleaning liquid. The driving shaft 1221 drives the cleaning belt 121 and the driven shaft 1222 to rotate. The cleaning belt 121 rotates in the cleaning liquid, and all parts of the cleaning belt 121 can be cleaned.

[0112] In a specific embodiment, the angle range for the cleaning assembly 12 to rotate around the rotating shaft 122 can be between 0° and 95°. For the case where the cleaning assembly 12 can rotate around the driving shaft 1221 and one end of the corresponding driven shaft 1222 of the cleaning assembly 12 opposite to the driving shaft 1221 can extend out of the opening of the accommodation groove 13 at the bottom of the housing 11, the rotatable angle range for the cleaning assembly 12 to rotate around the driving shaft 1221 can be 0° - 95°. It can be understood that the rotation angle should be greater than 0° so that one end of the corresponding driven shaft 1222 of the cleaning assembly 12 can extend out of the housing 11.

[0113] And, as Figure 8 shown, when the rotation angle is 90°, the cleaning assembly 12 is perpendicular to the opening at the bottom of the accommodation groove 13. In this embodiment, by making the rotation angle less than 95°, it is avoided that the rotation angle of the cleaning assembly 12 is too large, resulting in one end of the corresponding driving shaft 1221 of the cleaning assembly 12 abutting against the inner side wall 2113 of the accommodation groove 13, or the need to increase the volume of the accommodation groove 13, so that there is a large gap between the outer edge of the cleaning assembly 12 and the accommodation groove 13, or the inner side wall 2113 at one end of the driving shaft 1221 of the accommodation groove 13 corresponding to the cleaning assembly 12 is set as an inclined surface inclined away from the cleaning assembly 12. All these will increase the overall volume of the floor brush 1 or reduce the internal space of the housing 11 adjacent to the driving shaft 1221, and may cause other components in the housing 11 to be unable to be installed.

[0114] It should be noted that the larger the rotation angle of the cleaning assembly 12 around the driving shaft 1221, the larger the volume ratio of the part where one end of the corresponding driven shaft 1222 of the cleaning assembly 12 extends out of the housing 11, that is, the larger the volume of the cleaning assembly 12 exposed outside the housing 11, and thus the more parts of the cleaning assembly 12 are immersed in the cleaning liquid. By controlling the proportion of the part of the cleaning assembly 12 exposed outside the housing 11 within a suitable range, it is avoided that too many parts are immersed in the cleaning liquid due to too much exposure of the cleaning assembly 12, and the cleaning liquid may damage the rotating shaft 122 or other parts of the cleaning assembly 12.

[0115] For the fixation of the two rotating shafts 122 in the cleaning assembly 12, in one possible implementation, the cleaning assembly 12 may further include a bracket 123, and the rotating shafts 122 are arranged on the bracket 123. As Figure 5 , Figure 6 and Figure 9 shown, the cleaning assembly 12 further includes a bracket 123. The two rotating shafts 122 are both connected to the bracket 123, and the two rotating shafts 122 are fixed into an integral structure through the bracket 123. Exemplarily, for the side-by-side and spaced arrangement of the two rotating shafts 122, both ends of the two rotating shafts 122 can be connected to and relatively fixed to the bracket 123, and the bracket 123 can make the two fixed rotating shafts 122 be side by side and have a spacing structure between them.

[0116] The two rotating shafts 122 are fixed into an integral structure through the bracket 123, and the cleaning belt 121 is sleeved outside the two rotating shafts 122. In this way, the bracket 123, the two rotating shafts 122 and the cleaning belt 121 can form a whole, that is, the cleaning assembly 12 can be assembled into an integral structure, which is convenient for the installation and disassembly of the cleaning assembly 12. When one end of the corresponding driven shaft 1222 of the cleaning assembly 12 extends out from the opening of the receiving groove 13 of the housing 11, the bracket 123 of the corresponding driven shaft 1222 also extends out from the opening.

[0117] In order to make the driving shaft 1221 rotate to drive the cleaning belt 121 and the driven shaft 1222 to rotate, optionally, the floor brush 1 may further include a driving unit 14. The driving unit 14 is connected to at least one rotating shaft 122 and is used to drive the rotating shaft 122 to rotate. As Figure 3 and Figure 6 shown, the floor brush 1 may further be provided with a driving unit 14. The driving unit 14 is connected to at least one rotating shaft 122 among the driving shaft 1221 and the driven shaft 1222. The driving unit 14 can drive the rotating shaft 122 connected thereto to rotate. By driving the rotating shaft 122 by the driving unit 14, the rotating shaft 122 drives the cleaning belt 121 to rotate.

[0118] Since the cleaning belt 121 is sleeved outside the driving shaft 1221 and the driven shaft 1222, that is, the inner surface of the cleaning belt 121 and the outer surfaces of the driving shaft 1221 and the driven shaft 1222 are in contact with each other. The driving unit 14 can be connected only to the driving shaft 1221 and drive the driving shaft 1221 to rotate. By driving the rotation of the driving shaft 1221, the cleaning belt 121 sleeved on its outer surface is driven to rotate. Since the driven shaft 1222 is also in contact with the cleaning belt 121, the rotation of the cleaning belt 121 can drive the driven shaft 1222 to rotate; alternatively, the driving unit 14 can be connected to both the driving shaft 1221 and the driven shaft 1222 at the same time, and the driving unit 14 drives the driving shaft 1221 and the driven shaft 1222 to rotate simultaneously. In this way, both the driving shaft 1221 and the driven shaft 1222 can rotate synchronously, ensuring the stable rotation of the cleaning belt 121 sleeved on the outer surfaces of both.

[0119] As Figures 10 to 12 shown, the floor brush 1 may further include a water tank 15, and the water tank 15 is arranged on the housing 11. In this embodiment, the water tank 15 is arranged in the floor brush 1, and the water tank 15 is used to supply cleaning water to the floor brush 1, and the floor brush 1 cleans the floor with the cleaning water. It can be understood that the cleaning water in the water tank 15 is used to be sprayed onto the surface of the cleaning belt 121 of the cleaning assembly 12 to wet the cleaning belt 121. By moving the wet cleaning belt 121 in contact with the floor, the cleaning belt 121 has a better cleaning effect on the floor.

[0120] Among them, in order to make the water tank 15 have a better reasonable layout and avoid the water tank 15 occupying extra space volume, the water tank 15 can be arranged on the housing 11 of the floor brush 1. In this way, the water tank 15 does not occupy extra space, and at least part of the structure of the water tank 15 can be exposed outside the housing 11, which is beneficial to the installation and removal of the water tank 15.

[0121] Regarding the layout of the driving unit 14 and the water tank 15 in the housing 11, in a possible implementation manner, the driving unit 14 and the water tank 15 can be respectively arranged on both sides of the central axis of the housing 11. As Figure 3 shown, by respectively arranging the driving unit 14 and the water tank 15 on both sides of the central axis of the housing 11, the layout of the driving unit 14 and the water tank 15 can be made more reasonable. On the one hand, the driving unit 14 and the water tank 15 are arranged on the same side of the housing 11. For example, they are arranged on the rear side of the housing 11 opposite to the dust suction port 111, so that the space of the housing 11 can be saved; on the other hand, the driving unit 14 and the water tank 15 are at the opposite ends on the same side of the housing 11, so that it is convenient to connect the driving unit 14 and the water tank 15, and the driving unit 14 can control the water tank 15 to supply water to the cleaning assembly 12. When the floor brush 1 includes a dust suction air duct 113, the dust suction air duct 113 can be located on the central axis and extend along the central axis. At this time, the driving unit 14 and the water tank 15 can be located on both sides of the dust suction air duct 113.

[0122] Optionally, an installation groove 112 may be formed at the top of the housing 11. The shape of the installation groove 112 matches the shape of the water tank 15, and the water tank 15 is disposed within the installation groove 112. A water supply port 1121 is formed on the groove wall of the installation groove 112, and the water supply port 1121 communicates with the receiving groove 13.

[0123] As Figures 10 to 12 shown, by forming the installation groove 112 at the top of the housing 11 of the floor brush 1 and making the shape of the installation groove 112 match the shape of the water tank 15, the water tank 15 is disposed within the installation groove 112, so that the water tank 15 can be fixed to the housing 11. Moreover, since the water tank 15 is located at the top of the housing 11, the bottom wall of the installation groove 112 can support the water tank 15 to ensure the stability of the water tank 15. In addition, it is convenient to install and remove the water tank 15. The box body of the water tank 15 can be made of a transparent material. Since the water tank 15 is exposed at the top of the housing 11, the user can observe the water volume in the water tank 15 at any time, and thus can remove the water tank 15 in time to add water when the water volume in the water tank 15 is insufficient.

[0124] In addition, by forming the water supply port 1121 on the groove wall of the installation groove 112, the water outlet of the water tank 15 can correspond to and communicate with the water supply port 1121, and the water supply port 1121 of the installation groove 112 communicates with the receiving groove 13, so that the water tank 15 can communicate with the receiving groove 13. Exemplarily, the water outlet of the water tank 15 can communicate with the receiving groove 13 through a water pipe, so that the water in the water tank 15 can be delivered to the receiving groove 13 and finally supplied to the cleaning assembly 12.

[0125] Specifically, as Figure 12 shown, at least a part of the bottom of the installation groove 112 may be located above the cleaning assembly 12, and the shape of the area of the bottom of the installation groove 112 located above the cleaning assembly 12 matches the shape of the cleaning assembly 12. In order to reduce the size of the housing 11, except for the part corresponding to the receiving groove 13, the parts of the housing 11 on both sides of the receiving groove 13 are relatively small. In order to reasonably arrange the installation groove 112 on the housing 11, at least a part of the bottom of the installation groove 112 is located above the cleaning assembly 12, that is, at least a part of the structure of the water tank 15 is also located above the cleaning assembly 12, so that the volume of the housing 11 can be reduced, the layout of the water tank 15 on the housing 11 can be made more compact, and thus the portability and flexibility of the floor brush 1 can be improved.

[0126] The part of the bottom wall of the housing 11 corresponding to the receiving groove 13 matches the shape of the cleaning assembly 12 below the receiving groove 13. Thus, the area of the bottom of the installation groove 112 located above the cleaning assembly 12 matches the shape of this part of the cleaning assembly 12. Similarly, the shape of the corresponding part of the box body of the water tank 15 located within the installation groove 112 matches the shape of the corresponding part of the cleaning assembly 12, which will not be elaborated here.

[0127] In addition, as Figure 10 shown, the top surface of the water tank 15 can be flush with the top of the housing 11. By making the top surface of the water tank 15 flush with the top of the housing 11, after the water tank 15 is installed in the installation groove 112, the top of the water tank 15 and the upper surface of the floor brush 1 housing 11 are in a horizontal plane. On the one hand, the water tank 15 is completely accommodated in the installation groove 112, so the installation groove 112 has a good supporting effect on the water tank 15, which can improve the stability of the water tank 15; on the other hand, it can make the top surface of the housing 11 have better flatness and make the appearance of the floor brush 1 more simple and generous.

[0128] In addition, on both sides of the edge of the installation groove 112 at the top of the housing 11, recessed portions 1122 can be provided. The recessed portions 1122 can expose partial structures of the side wall 2113 of the water tank 15, so that it is convenient for the user to hold the side wall 2113 of the water tank 15 through the recessed portions 1122, and the water tank 15 can be more easily taken out of the installation groove 112.

[0129] As Figure 4 , Figure 5 and Figure 13 shown, in a possible implementation manner, the cleaning belt 121 can include an annular base belt 1211 and a cleaning member 1212 provided on the outer surface of the base belt 1211. The part of the cleaning member 1212 rotating between the two rotating shafts 122 forms a cleaning surface 124.

[0130] The cleaning belt 121 includes a base belt 1211 and a cleaning member 1212. The base belt 1211 is a transmission member. The base belt 1211 is in a cylindrical structure. The cylindrical base belt 1211 is sleeved outside the two rotating shafts 122 to form an annular base belt 1211 that matches the overall shape formed by the two rotating shafts 122. The rotating shafts 122 drive the base belt 1211 to rotate synchronously; the cleaning member 1212 is provided outside the base belt 1211. The cleaning member 1212 is located on the outermost side of the cleaning assembly 12. When the cleaning assembly 12 works, the cleaning member 1212 contacts the ground, and the ground is cleaned by the frictional contact between the cleaning member 1212 and the ground.

[0131] The rotation of the rotating shaft 122 drives the rotation of the baseband 1211. The cleaning member 1212 provided on the outer surface of the baseband 1211 is relatively fixed to the baseband 1211. Therefore, the rotating shaft 122 drives the baseband 1211 and the cleaning member 1212 to rotate synchronously. In this way, the cleaning member 1212 provided on the outermost side of the cleaning assembly 12 is in rotational contact with the ground, and the generated frictional force is relatively large, which can improve the cleaning effect of the cleaning assembly 12 on the ground. Among them, the cleaning member 1212 is a flexible member, and the baseband 1211 can be made of rubber or silica gel to increase the frictional force between the baseband 1211, the rotating shaft 122 and the cleaning member 1212, and ensure that the baseband 1211 can play a stable transmission role.

[0132] Among them, as Figure 14 shown, the two ends of the cleaning member 1212 can be spliced together to surround the outside of the baseband 1211, and the splicing line 1212a formed by the cleaning member 1212 has an included angle with the axis of the rotating shaft 122. In this embodiment, the original shape of the cleaning member 1212 is a relatively thin sheet-like structure, and the edges of the cleaning member 1212 are spliced together to form an annular cleaning member 1212. The spliced annular cleaning member 1212 surrounds the outside of the baseband 1211. It can be understood that the spliced cleaning member 1212 is closely attached to the outer surface of the baseband 1211, so that the cleaning member 1212 is relatively fixed on the outer surface of the baseband 1211. The baseband 1211 drives the cleaning member 1212 to rotate synchronously, so that the cleaning member 1212 is in moving contact with the ground to clean the ground.

[0133] Moreover, in order to improve the flatness of the spliced cleaning member 1212 and make the cleaning member 1212 in stable contact with the ground, as Figure 14 shown, in this embodiment, the splicing line 1212a of the cleaning member 1212 sleeved on the outer surface of the baseband 1211 has an included angle with the axis of the rotating shaft 122, that is, the splicing line 1212a is inclined relative to the axis of the rotating shaft 122. In this way, the splicing line 1212a of the cleaning member 1212 is longer, and for the cleaning surface 124 of the cleaning member 1212 in moving contact with the ground, the cleaning surface 124 is rectangular, and there is an included angle between the splicing line 1212a and the side of the rectangle. That is, in the process of the cleaning member 1212 cleaning the ground, along the moving direction of the cleaning member 1212, the splicing line 1212a is not on a horizontal line. In this way, the flatness of the formed splicing line 1212a is better. During the movement of the cleaning member 1212, the splicing line 1212a has good contact with the ground and will not cause the cleaning assembly 12 to bounce, which can improve the cleaning effect of the cleaning assembly 12.

[0134] Specifically, as Figure 15As shown, the cleaning member 1212 can be in the shape of a parallelogram in the unfolded state. The original shape of the cleaning member 1212, that is, the shape of the cleaning member 1212 in the unfolded state, is a parallelogram. The parallelogram-shaped cleaning member 1212 is arranged on the outer surface of the base belt 1211 in a spiral winding manner. In this way, the splicing line 1212a formed between the edges of the cleaning members 1212 in adjacent areas is a spiral line. This can extend the splicing line 1212a of the splicing cloth, and the flatness of the cleaning members 1212 on both sides of the splicing line 1212a is relatively good. During the movement of the cleaning member 1212, the splicing line 1212a is in good contact with the ground, and the splicing line 1212a will not cause the cleaning assembly 12 to bounce, so as to ensure that the cleaning assembly 12 has a better cleaning effect.

[0135] As Figure 4 , Figure 5 and Figure 10 As shown, in a specific embodiment, the rotating shaft 122 may include a core shaft 1223 and a buffer layer 1224 located outside the core shaft 1223. The buffer layer 1224 is wrapped around the outer circumferential surface of the core shaft 1223. The rotating shaft 122 may include a core shaft 1223 and a buffer layer 1224 located outside the core shaft 1223. The buffer layer 1224 is wrapped around the outer circumferential surface of the core shaft 1223. The rotating shaft 122 of this embodiment is composed of a core shaft 1223 and a buffer layer 1224. The buffer layer 1224 is sleeved outside the core shaft 1223. The driving force of the driving unit 14 acts directly on the core shaft 1223. The buffer layer 1224 is fixed relative to the core shaft 1223, and the core shaft 1223 and the buffer layer 1224 rotate synchronously.

[0136] The core shaft 1223, as the structural main body of the rotating shaft 122, is usually made of a metal material so that the core shaft 1223 can support the buffer layer 1224 outside it, enabling the rotating shaft 122 to have sufficient structural strength and maintaining stability during rotation; furthermore, the core shaft 1223 made of a metal material can better transmit power, and the driving unit 14 can drive the core shaft 1223 to rotate better.

[0137] However, it is not advisable to directly sleeved the baseband 1211 outside the mandrel 1223 made of metal material. In this way, due to the small friction force between the mandrel 1223 and the baseband 1211, the stability of the baseband 1211 may be poor during the process of the rotating shaft 122 driving the baseband 1211 to rotate, and it is easy to slip and move on the outer surface of the mandrel 1223. Therefore, in this embodiment, a buffer layer 1224 is sleeved outside the mandrel 1223, and the baseband 1211 is sleeved outside the buffer layer 1224. The buffer layer 1224 has a certain buffering effect on the tension of the baseband 1211. Through the friction force between the buffer layer 1224 and the baseband 1211, the baseband 1211 can be firmly connected to the outer surface of the buffer layer 1224, avoiding relative movement between the baseband 1211 and the buffer layer 1224 and enabling the baseband 1211 to rotate smoothly. Exemplarily, the buffer layer 1224 can be a silicone layer or a rubber layer.

[0138] In a possible implementation manner, a water spraying assembly 16 can be arranged in the housing 11. The water spraying assembly 16 is communicated with the water tank 15 through a water supply port 1121. Among them, the water spraying assembly 16 is located above the cleaning assembly 12, and the water outlet side of the water spraying assembly 16 faces the cleaning assembly 12.

[0139] As Figure 3 、 Figure 6 and Figure 12 shown, the floor brush 1 of this embodiment is also provided with a water spraying assembly 16. The cleaning water is sprayed onto the cleaning assembly 12 through the water spraying assembly 16 to wet the cleaning member 1212 located on the outermost side of the cleaning assembly 12, and the floor is cleaned by the wetted cleaning member 1212. Usually, the water spraying assembly 16 is arranged at the top in the housing 11, and the water spraying assembly 16 is located above the cleaning assembly 12. The water outlet side of the water spraying assembly 16 faces the cleaning assembly 12, so as to ensure that the cleaning water in the water spraying assembly 16 can be sprayed onto the cleaning assembly 12.

[0140] Specifically, as Figure 3 shown, a water spraying chamber 114 can be arranged at the bottom of the housing 11 corresponding to the receiving groove 13. The water spraying assembly 16 can be installed in the water spraying chamber 114. The water spraying chamber 114 has an opening facing the cleaning assembly 12, and the water outlet side of the water spraying assembly 16 corresponds to this opening, so that the cleaning water sprayed out from the water outlet side can be sprayed onto the cleaning assembly 12. And, the water spraying assembly 16 is communicated with the water tank 15 through the water supply port 1121 of the installation groove 112. Exemplarily, one end of the water spraying assembly 16 is connected to a water pipe, and the other end of the water pipe passes through the water supply port 1121 of the installation groove 112 and is connected to the water tank 15. In this way, the cleaning water in the water tank 15 can be conveyed to the water spraying assembly 16 through the water pipe.

[0141] Optionally, walking wheels 17 can be installed at the bottom of the housing 11. As Figure 1As shown in the figure, by installing the walking wheels 17 at the bottom of the housing 11 of the floor brush 1, during the process of the floor brush 1 moving relative to the ground, the floor brush 1 makes rolling contact with the ground through the walking wheels 17, which facilitates the movement of the floor brush 1, and the flexibility and portability of the floor brush 1 are higher.

[0142] The floor brush provided in this embodiment is composed of a housing and a cleaning component. The interior of the housing is hollow and a receiving groove is formed on the outer surface of the bottom. The cleaning component is installed in the receiving groove. By making the receiving groove have an opening, and the opening is located at the bottom of the housing, the cleaning component can contact the ground through the opening to clean the ground; the cleaning component specifically includes a cleaning belt and two rotating shafts. The cleaning belt is annular and sleeved outside the two rotating shafts, and the two rotating shafts are arranged side by side at intervals. The two rotating shafts can drive the cleaning belt outside them to rotate synchronously, so that the outer circumferential surface of the cleaning belt forms a movable cleaning surface. Specifically, the part of the cleaning belt between the two rotating shafts contacts the ground to form a cleaning surface. On the one hand, the cleaning surface formed by the cleaning belt moves in contact with the ground, so the cleaning effect is better. On the other hand, since there is an interval between the two rotating shafts, the cleaning surface and the ground are in planar contact, and the contact area is large, so the cleaning efficiency is high.

[0143] Embodiment Two

[0144] Figure 17 It is a schematic structural diagram of the vacuum cleaner provided in Embodiment Two of the present invention; Figure 18 Provided for Embodiment Two of the present invention Figure 17 exploded view of Figure 19 Provided for Embodiment Two of the present invention Figure 17 cross-sectional view of

[0145] Figure 20 It is a schematic structural diagram of the cleaning base provided in Embodiment Two of the present invention.

[0146] As Figures 17 to 20 shown, this embodiment provides a vacuum cleaner, which includes a dust collection component and the floor brush 1 described in Embodiment One, and the dust collection ports 111 in the dust collection component and the floor brush 1 are communicated. Specifically, the vacuum cleaner includes the floor brush 1 and a dust collection component. The dust collection component may include a vacuum cleaner body and a connecting pipe. One end of the connecting pipe is communicated with the dust collection port 111 of the floor brush 1, and the other end of the connecting pipe is communicated with the vacuum cleaner body.

[0147] Among them, the vacuum cleaner body includes a housing. An air outlet is provided on the housing. A dust filter can also be provided inside the housing. The dust filter is communicated with a connecting pipe. A blower can also be provided inside the vacuum cleaner body, and the blower can be located near the air outlet. Among them, by rotating the blower, the air inside the vacuum cleaner body can be discharged, so that a negative pressure channel can be formed between the vacuum cleaner body, the connecting pipe and the floor brush 1. Furthermore, by using the pressure difference between the vacuum cleaner body and the outside world, the air together with dust can be sucked into the vacuum cleaner body from the dust suction port 111 of the floor brush 1 through the connecting pipe. The air and dust entering the vacuum cleaner body can be collected and filtered by the dust filter, and the air filtered by the dust filter is discharged to the outside of the vacuum cleaner body by the blower through the air outlet. Through the continuous circulation of air inside the vacuum cleaner, more dust can be collected into the dust filter to complete the cleaning function of the vacuum cleaner.

[0148] Among them, the specific structure, function and working principle of the floor brush 1 have been described in detail in the foregoing Embodiment 1, and will not be elaborated here.

[0149] As Figures 17 to 20 shown, for the convenience of cleaning the cleaning component 12, optionally, the vacuum cleaner may further include a cleaning base 2. A receiving groove 21 is formed at the top of the cleaning base 2. The receiving groove 21 includes a receiving cavity 211 and a first supporting portion 212 surrounding the receiving cavity 211. Among them, the bottom of the housing 11 is supported on the first supporting portion 212, and the part of the cleaning component 12 extending below the housing 11 is located in the receiving cavity 211.

[0150] In this embodiment, the vacuum cleaner includes a cleaning base 2. When the cleaning component 12 of the floor brush 1 needs to be cleaned, the cleaning base 2 can be used in combination with the floor brush 1 to help clean the cleaning component 12, making the cleaning of the cleaning component 12 more convenient.

[0151] Specifically, as Figure 17 shown, when cleaning the cleaning component 12, the floor brush 1 can be placed above the cleaning base 2. The top of the cleaning base 2 has a receiving groove 21. The receiving groove 21 has an opening facing the bottom of the housing 11 of the floor brush 1. The shape of the receiving groove 21 can match the shape of the bottom of the floor brush 1, which can improve the stability of the cleaning base 2 in supporting the floor brush 1 and can better fix the position of the floor brush 1.

[0152] Among them, as Figure 20As shown in the figure, the accommodation groove 21 includes an accommodation cavity 211 and a first support portion 212 surrounding the outside of the accommodation cavity 211. The bottom of the floor brush 1 is supported above the accommodation groove 21. When one end of the corresponding driven shaft 1222 of the cleaning assembly 12 extends outside the housing 11, the part of the cleaning assembly 12 extending outside the housing 11 can extend into the accommodation cavity 211. The accommodation cavity 211 can accommodate and support this part of the cleaning assembly 12. A cleaning liquid can be filled in the accommodation cavity 211, and the cleaning liquid should be able to at least submerge the bottom end of the outermost cleaning part 1212 of the cleaning assembly 12, so that the lower part of the cleaning part 1212 is immersed in the cleaning liquid. Then, the cleaning assembly 12 is driven to rotate by the driving shaft 1221, and the cleaning part 1212 rotates in the cleaning liquid, so that the cleaning liquid can be used to clean the cleaning part 1212.

[0153] A first support portion 212 is disposed around the outer periphery of the accommodation cavity 211, and the shape of the first support portion 212 matches the shape of the bottom of the housing 11 located outside the accommodation groove 13. When the floor brush 1 is placed above the accommodation groove 21, the bottom of the housing 11 of the floor brush 1 is supported on the first support portion 212. The floor brush 1 is supported above the accommodation cavity 211 through the first support portion 212, so that one end of the corresponding driven shaft 1222 of the cleaning assembly 12 can fall into the accommodation cavity 211, and the first support portion 212 can limit the position of the housing 11 above the accommodation groove 21.

[0154] Specifically, as Figure 20 shown in the figure, the accommodation cavity 211 may include a bottom surface 2111 and a side surface 2112. The side surface 2112 faces the cleaning surface 124 of the cleaning assembly 12, and the side surface 2112 is an inclined surface inclined relative to the bottom surface 2111. The accommodation cavity 211 on the cleaning base 2 for accommodating the cleaning assembly 12 extending from the bottom of the housing 11 of the floor brush 1 may include a bottom surface 2111 and a side surface 2112. The bottom end of the cleaning assembly 12 exposed outside the housing 11 of the floor brush 1 corresponds to the ground of the accommodation cavity 211, and the cleaning surface 124 of the cleaning assembly 12 located between the two rotating shafts 122 corresponds to the side surface 2112 of the accommodation cavity 211. Since the exposed part of the cleaning assembly 12 is inclined relative to the bottom of the housing 11, the side surface 2112 of the accommodation cavity 211 may also be an inclined surface matching the exposed part of the cleaning assembly 12.

[0155] In a specific embodiment, the inclination angle of the side surface 2112 relative to the bottom surface 2111 can be between 0° and 90°. The inclination angle of the side surface 2112 of the accommodating cavity 211 affects the volume of the cleaning liquid that the accommodating cavity 211 can hold. By setting the side surface 2112 as an inclined surface that matches the inclination angle of the cleaning component 12 extending outside the housing 11, the cross-section of the accommodating cavity 211 can be in the shape of an inverted trapezoid. It is possible to reduce the volume of the accommodating cavity 211 while satisfying the condition that the accommodating cavity 211 can hold the cleaning component 12. In this way, less cleaning liquid is required in the accommodating cavity 211 to meet the condition of submerging the lower part of the cleaning component 12, which can improve the cleaning efficiency of the cleaning liquid and save the cost of cleaning the cleaning component 12.

[0156] Exemplarily, the inclination angle of the side surface 2112 relative to the bottom surface 2111 can be 30°, 40°, 45°, 50° or 60°, etc. This embodiment does not make specific limitations in this regard.

[0157] Optionally, as Figure 20 shown, the accommodating cavity 211 may further include side walls 2113 at both ends in the length direction of the accommodating cavity 211. The side walls 2113 may have second support portions 213. The second support portions 213 are higher than the bottom surface 2111, and the edges of the cleaning component 12 are supported on the second support portions 213.

[0158] Both ends of the accommodating cavity 211 in its length direction have side walls 2113, and the side walls 2113 have second support portions 213. The shape of the second support portions 213 matches the shape of the lower part of the cleaning component 12 extending outside the housing 11. After the cleaning component 12 extends into the accommodating cavity 211, both ends of the cleaning component 12 are lapped on the second support portions 213. The second support portions 213 can support the cleaning component 12 and improve the stability of the cleaning component 12. It can be understood that the second support portions 213 are higher than the bottom surface 2111, that is, the bottommost part of the second support portions 213 is higher than the bottom surface 2111. Since the lower part of the cleaning component 12 abuts against the second support portions 213, there is a gap between the bottom of the cleaning component 12 and the bottom surface 2111 of the accommodating cavity 211. During the rotation of the cleaning component 12, the bottom surface 2111 will not wear the cleaning member 1212.

[0159] Specifically, the second support portion 213 may have a support surface 2131. The support surface 2131 fits the cleaning surface 124, and the inclination angle of the support surface 2131 relative to the bottom surface 2111 is between 30° and 60°. As Figure 19As shown, the second support portion 213 has a support surface 2131. The support surface 2131 corresponds to the cleaning surface 124 of the cleaning assembly 12 located between two rotating shafts 122, and the cleaning surface 124 is in contact with the support surface 2131. In addition, the second support portion 213 also has an arc surface that is in contact with one end of the corresponding driven shaft 1222 of the cleaning assembly 12. The arc surface and the support surface 2131 together form the second support portion 213.

[0160] Among them, the inclination angle range of the support surface 2131 relative to the bottom surface 2111 is 30° - 60°. Correspondingly, the inclination angle of the cleaning assembly 12 supported on the second support portion 213 relative to the bottom surface 2111 is between 30° - 60°. This can ensure that the lower part of the cleaning assembly 12 can be immersed in the cleaning liquid in the accommodation cavity 211 to clean the cleaning assembly 12. At the same time, it can avoid excessive immersion of the cleaning assembly 12 in the cleaning liquid, which may cause damage to the cleaning assembly 12. Exemplarily, the inclination angle of the support surface 2131 relative to the bottom surface 2111 can be 30°, 40°, 45°, 50° or 60°, etc. This embodiment does not make specific limitations on this.

[0161] In addition, a water level scale line can be provided on the side wall 2113 of the accommodation cavity 211. By providing a water level scale line on the side wall 2113 of the accommodation cavity 211, it is convenient for the user to confirm the volume of the cleaning liquid added to the accommodation cavity 211, and avoid adding too little cleaning liquid so that the bottom of the cleaning assembly 12 cannot contact the cleaning liquid, or avoid adding too much cleaning liquid so that the part of the cleaning assembly 12 immersed in the cleaning liquid is excessive. For example, the core shaft 1223 of the rotating shaft 122 of the cleaning assembly 12 is partially immersed in the cleaning liquid. Since the core shaft 1223 is usually made of a metal material, this may cause damage to the core shaft 1223. It is more appropriate that the cleaning liquid only immerses at most the buffer layer 1224 made of a plastic material outside the rotating shaft 122.

[0162] The vacuum cleaner provided in this embodiment includes a floor brush and a dust collection component. The dust collection component may include a vacuum cleaner body and a connecting pipe. One end of the connecting pipe is communicated with the dust suction port of the floor brush, and the other end of the connecting pipe is communicated with the vacuum cleaner body. Among them, the floor brush is composed of a housing and a cleaning component. The inside of the housing is hollow, and a receiving groove is formed on the outer surface of the bottom. The cleaning component is installed in the receiving groove. By making the receiving groove have an opening, and the opening is located at the bottom of the housing, the cleaning component can contact the ground through the opening to clean the ground; the cleaning component specifically includes a cleaning belt and two rotating shafts. The cleaning belt is annular and sleeved outside the two rotating shafts, and the two rotating shafts are arranged side by side at intervals. The two rotating shafts can drive the cleaning belt outside them to rotate synchronously, so that the outer circumferential surface of the cleaning belt forms a movable cleaning surface. Specifically, the part of the cleaning belt located between the two rotating shafts contacts the ground to form a cleaning surface. On the one hand, the cleaning surface formed by the cleaning belt moves in contact with the ground, so the cleaning effect is better. On the other hand, since there is an interval between the two rotating shafts, the cleaning surface and the ground are in plane contact, and the contact area is large, so the cleaning efficiency is high.

[0163] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or equivalently replace some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
