Description

Technical Field

[0001] This invention relates to the field of household appliance technology, specifically to a rotary brush assembly, a floor scrubber brush, and a floor scrubber. Background Technology

[0002] A floor scrubber mainly consists of a floor brush, a wastewater tank, a clean water tank, a motor, and a battery assembly. The floor brush comprises a roller brush, a water spray assembly, a squeegee, a suction channel, a motor, and a water pump. The water spray assembly sprays water onto the roller brush, wetting it, and the roller brush rolls on the floor to achieve the effect of washing and mopping. The squeegee scrapes off the wastewater, dust, and other debris from the roller brush and sends it to the suction channel to be sucked into the wastewater tank.

[0003] However, in actual use, existing floor scrubbers often have hair that gets tangled on the roller brush, making it difficult to remove and resulting in a poor user experience. Summary of the Invention

[0004] In view of this, the present invention provides a rotary brush assembly, a floor scrubber brush, and a floor scrubber to solve the problem of hair getting tangled in the roller brush of existing floor scrubbers, which affects the user experience.

[0005] In a first aspect, the present invention provides a rotary brush assembly for cleaning equipment, comprising: A housing, wherein the housing is provided with at least two mounting holes; At least one set of rotary brushes, the rotary brushes including a first brush body and a second brush body, the first brush body and the second brush body being respectively disposed in the mounting hole, the ends of the first brush body and the second brush body having a scraping device, the scraping device being adapted to scrape off dirt, wherein the scraping device of the first brush body is horizontally arranged, and the scraping device of the second brush body is inclinedly arranged; A first drive assembly is connected to the first brush body and the second brush body and is adapted to drive the first brush body and the second brush body to rotate; The second drive component is connected to the first brush body and the second brush body and is adapted to drive the first brush body and the second brush body to move up and down; The control system, connected to the second drive assembly, is adapted to control the second drive assembly to drive the first brush body to rise and separate dirt when the first drive assembly drives the first brush body and the second brush body to rotate to a preset position, and the second brush body to descend to receive the dirt separated by the first brush body, and continue to rotate to send the dirt into the suction port of the cleaning device.

[0006] Beneficial effects: By configuring the rotary brush to include a first brush body and a second brush body, with the scraping device of the first brush body being horizontally positioned, when the first brush body scrapes dirt such as hair and rotates to a preset position, the control system controls the second drive component to drive the first brush body upward. Due to inertia, the hair will separate from the first brush body. At this time, the control system controls the second drive component to drive the second brush body downward. Since the scraping device of the second brush body is tilted, it can effectively catch the hair separated from the first brush body. The second brush body continues to rotate, sending the hair into the suction port of the cleaning device. By relaying the scraping devices of the first and second brush bodies, the hair scraped by the first brush body is sent into the suction port of the cleaning device, preventing the hair scraped by both brush bodies from getting tangled and forming a ball during rotation, thus improving the user experience.

[0007] In one alternative embodiment, the angle between the scraping device of the second brush body and the horizontal direction is 15° to 90°.

[0008] Beneficial effects: By setting the angle between the scraping device of the second brush body and the horizontal direction to 15° to 90°, the second brush body can better catch the dirt separated by the first brush body. This prevents the second brush body from not being able to catch the dirt scraped by the first brush body if the angle is too small, and from not being able to catch the dirt scraped by the first brush body if the angle is too large. When the angle is too large, the scraping device of the second brush body lags too much behind the scraping device of the first brush body when it shakes the hair, and cannot form a good relay for the first brush body.

[0009] In one alternative implementation, the rotary brush is provided with at least two sets.

[0010] Beneficial effect: By setting at least two sets of rotating brushes, cleaning efficiency can be improved.

[0011] In one alternative embodiment, the rotary brush is provided in two sets, and the two sets of rotary brushes rotate in opposite directions.

[0012] Beneficial effects: By setting two sets of rotating brushes with opposite rotation directions (e.g., the left rotating brush rotates clockwise and the right rotating brush rotates counterclockwise), dirt can be better gathered towards the center and more easily sucked into the suction port.

[0013] In one alternative embodiment, the first brush body of each set of rotary brushes is disposed near the outer side of the housing, and the second brush body is disposed inside the first brush body.

[0014] Beneficial effects: By placing the first brush body on the outer side and the second brush body on the inner side of the first brush body, dirt can be transferred from the outside to the inside and to the suction port more effectively, thus improving cleaning efficiency.

[0015] In one optional implementation, the second driving component includes: At least two first magnetic components, each having magnetic properties, are arranged in a one-to-one correspondence with the first brush body and the second brush body. The first magnetic components are fixedly connected to the housing and are arranged axially on the outside of the first brush body and the second brush body, and are adapted to provide axial magnetic force to the first brush body and the second brush body. The control system is connected to the first magnetic component and is adapted to control the magnetic strength of the first magnetic component while the first brush body and the second brush body rotate, so that the first brush body and the second brush body can move up and down, so that the first brush body and the second brush body can be in an adhesive state when descending and a separation state when rising.

[0016] Beneficial effects: By setting the second drive component as a first magnetic component with magnetism, the control system can control the magnetic strength of the first magnetic component, thereby controlling the lifting and lowering of the first and second brush bodies. After the first and second brush bodies descend, the scraping device scrapes off dirt such as hair. The control system controls the magnetism of the first magnetic component, causing the first brush body to rise rapidly during rotation. Under the suction force of the suction port and the inertia of the hair, the hair will separate from the scraping device, allowing the first brush body to shake off the stuck hair, preventing hair from getting tangled on the first brush body and improving the separation effect.

[0017] In one alternative implementation, the first magnetic component includes: A first magnet assembly is disposed on the outside of the first brush body and the second brush body. The first magnet assembly includes a first magnet and a second magnet arranged along the axial direction. The magnetic properties of adjacent sides of the first magnet and the second magnet are opposite. The control system is connected to the first magnet. The second magnet group is disposed on the outside of the first brush body and the second brush body. The second magnet group and the first magnet group are spaced apart along the axial direction. The second magnet group includes a third magnet and a fourth magnet disposed along the axial direction. The magnetic properties of the third magnet and the fourth magnet are opposite on adjacent sides. The first magnet assembly and the second magnet assembly are adapted to provide opposing forces to the first brush body and the second brush body, and the control system is adapted to control the magnetism of the first magnet so that the first brush body and the second brush body are subjected to force balance in the adhesive state.

[0018] Beneficial effects: By setting up two magnet groups, which provide opposite forces to the first and second brush bodies (e.g., one magnet group provides downward pressure and the other provides upward buoyancy), and the control system is connected to the first magnet to adjust its magnetic strength, the forces on the first and second brush bodies are balanced when they are stuck together, so as not to affect the first and second brush bodies from scraping dirt or sticking to hair.

[0019] In one optional embodiment, the first magnet group is disposed at the other end of the first brush body and the second brush body, and the control system is adapted to reduce the magnetism of the first magnet when the first brush body and the second brush body rotate to a preset position, so that the rising of the first brush body and the second brush body has the separation state.

[0020] Beneficial effects: By setting a first magnet group at the other end of the first and second brush bodies, the first and second brush bodies are subjected to a downward driving force due to the opposite polarities of the two magnets in the first magnet group. Conversely, the first and second brush bodies are subjected to an upward buoyancy due to the opposite polarities of the two magnets in the second magnet group. When the control system controls the magnetism of the first magnet to balance the magnetic forces on the first and second brush bodies, the first and second brush bodies are in a suspended state. When the control system reduces the magnetism of the first magnet, breaking the force balance of the first and second brush bodies, the first and second brush bodies will rise to achieve separation from the dirt. Secondly, the present invention also provides a floor scrubber brush, comprising: The bottom shell has a through hole and a suction port. The through hole and the mounting hole are respectively arranged one-to-one. The suction port is located on one side of the dirt scraping device. The aforementioned rotary brush assembly has the rotary brush disposed at the through hole.

[0021] Beneficial effects: Since the floor scrubber brush includes the aforementioned rotary brush assembly, it has the same beneficial effects as the rotary brush, which will not be elaborated here.

[0022] Thirdly, the present invention also provides a floor scrubbing machine, including: the floor scrubbing machine brush described above.

[0023] Beneficial effects: Since the floor scrubber includes the floor scrubber brush mentioned above, it has the same beneficial effects as the floor scrubber brush, which will not be repeated here. Attached Figure Description

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] The following is combined with Figures 1 to 8 The following describes embodiments of the present invention.

[0029] According to an embodiment of the present invention, in one aspect, a rotary brush assembly is provided for a cleaning device, comprising: a housing having at least two mounting holes; at least one set of rotary brushes, each rotary brush including a first brush body 1 and a second brush body 18, the first brush body 1 and the second brush body 18 being correspondingly disposed in the mounting holes, the ends of the first brush body 1 and the second brush body 18 having scraping devices 101 adapted to scrape off dirt, wherein the scraping devices 101 of the first brush body 1 are horizontally arranged, and the scraping devices 101 of the second brush body 18 are inclinedly arranged; a first drive assembly, and... The first brush body 1 and the second brush body 18 are connected and adapted to drive the first brush body 1 and the second brush body 18 to rotate; the second drive assembly is connected to the first brush body 1 and the second brush body 18 and adapted to drive the first brush body 1 and the second brush body 18 to rise and fall; the control system is connected to the second drive assembly and adapted to control the second drive assembly to drive the first brush body 1 to rise and separate dirt when the first drive assembly drives the first brush body 1 and the second brush body 18 to rotate to a preset position, and the second brush body 18 to fall to receive the dirt separated by the first brush body 1, and continue to rotate to send the dirt into the suction port 171 of the cleaning equipment.

[0030] In this embodiment, the cleaning equipment is a floor scrubber. Alternatively, the cleaning equipment could be a washing machine, a mopping machine, a washing and mopping machine, etc.

[0031] By configuring the rotary brush to include a first brush body 1 and a second brush body 18, with the scraping device 101 of the first brush body 1 being horizontally positioned, when the first brush body 1 scrapes dirt such as hair and rotates to a preset position, the control system controls the second drive component to drive the first brush body 1 to rise. Due to inertia, the hair will separate from the first brush body 1. At this time, the control system controls the second drive component to drive the second brush body 18 to descend. Since the scraping device 101 of the second brush body 18 is tilted, it can effectively catch the hair separated from the first brush body 1. The second brush body 18 continues to rotate, sending the hair into the suction port 171 of the floor scrubber. By relaying the scraping devices 101 of the first brush body 1 and the second brush body 18, the hair scraped by the first brush body 1 is sent into the suction port 171 of the floor scrubber, preventing the hair scraped by the scraping devices 101 of both the first brush body 1 and the second brush body 18 from getting tangled and forming a ball during rotation, thus improving the user experience.

[0032] In this embodiment, the angle between the scraping device 101 of the second brush body 18 and the horizontal direction is 15° to 90°. By setting the angle between the scraping device 101 of the second brush body 18 and the horizontal direction to 15° to 90°, the second brush body 18 can better catch the dirt separated by the first brush body 1. This prevents the angle from being too small, which would prevent it from not being able to completely catch the dirt scraped by the first brush body 1, and from being too large, which would cause the scraping device 101 of the second brush body 18 to lag too much in shaking off the hair compared to the scraping device 101 of the first brush body 1, thus failing to provide a good relay of force to the first brush body 1. As an alternative implementation, the angle between the scraping device 101 of the second brush body 18 and the horizontal direction can also be other angles, which are not specifically limited here.

[0033] In this embodiment, there are two sets of rotary brushes, and the two sets of rotary brushes rotate in opposite directions. By setting the rotary brushes in two sets with opposite rotation directions (e.g., the left rotary brush rotates clockwise and the right rotary brush rotates counterclockwise), dirt can be better gathered towards the center and more easily sucked into the suction inlet 171. As an alternative implementation, there can also be three, four, or more sets of rotary brushes to improve cleaning efficiency. As an alternative implementation, each set of rotary brushes can rotate in the same direction, or adjacent rotary brushes can rotate in opposite directions.

[0034] In each set of rotary brushes, the first brush body 1 is positioned near the outer side of the housing, and the second brush body 18 is positioned inside the first brush body 1. By positioning the first brush body 1 on the outer side and the second brush body 18 on the inner side of the first brush body 1, dirt can be more effectively transferred from the outside to the inside and more effectively transferred to the suction port 171, thus improving cleaning efficiency. As an alternative implementation, the second brush body 18 can also be positioned near the outer side of the housing, with the second brush body 18 positioned outside the first brush body 1.

[0035] The second driving component in this embodiment includes: at least two first magnetic components, each having magnetism, and the first magnetic components are arranged one-to-one with the first brush body 1 and the second brush body 18. The first magnetic components are fixedly connected to the housing and are axially disposed on the outside of the first brush body 1 and the second brush body 18, suitable for providing axial force to the first brush body 1 and the second brush body 18; the control system is connected to the first magnetic components and is suitable for controlling the magnetic magnitude of the first magnetic components while the first brush body 1 and the second brush body 18 rotate, so that the first brush body 1 and the second brush body 18 can move up and down, so that the first brush body 1 and the second brush body 18 have an adhesive state when descending and a separation state when rising.

[0036] By setting the second drive component as a first magnetic component, the control system can control the magnetic strength of the first magnetic component, thereby controlling the lifting and lowering of the first brush body 1 and the second brush body 18. After the first brush body 1 and the second brush body 18 descend, the scraping device 101 scrapes up dirt such as hair. The control system controls the magnetism of the first magnetic component, causing the first brush body 1 and the second brush body 18 to rise rapidly during rotation. Under the suction of the floor scrubber inlet 171 and the inertia of the hair, the hair will separate from the scraping device 101, so that the first brush body 1 and the second brush body 18 can shake off the stuck hair, preventing the hair from getting tangled on the first brush body 1 and the second brush body 18, thus improving the separation effect.

[0037] Alternatively, the second driving component can be any other mechanism that can drive the first brush body 1 and the second brush body 18 to rise and fall, such as a motor combined with a gear and rack to achieve the rising and falling of the first brush body 1 and the second brush body 18.

[0038] Since the first magnetic component has the same configuration relationship with the first brush body 1 and the second brush body 18, the following description will take the configuration relationship between the first magnetic component and the first brush body 1 as an example.

[0039] like Figure 3 As shown, the first magnetic component includes: a first magnet group disposed on the outside of the first brush body 1, the first magnet group including a first magnet 2 and a second magnet 3 arranged along the axial direction, as shown. Figure 4 As shown, the magnetic properties of the first magnet 2 and the second magnet 3 are opposite on adjacent sides, and the control system is connected to the first magnet 2. A second magnet group is located on the outside of the first brush body 1, spaced axially from the first magnet group. The second magnet group includes a third magnet 4 and a fourth magnet 5 arranged axially, with opposite magnetic properties on adjacent sides of the third magnet 4 and the fourth magnet 5. The first and second magnet groups are adapted to provide opposite forces to the first brush body 1, and the control system is adapted to control the magnetism of the first magnet 2 to balance the forces on the first brush body 1 when it is stuck together. By setting two magnet groups that provide opposite forces to the first brush body 1 (e.g., one magnet group provides downward pressure and the other provides upward buoyancy), and by connecting the control system to the first magnet 2 and adjusting the magnetism of the first magnet 2, the forces on the first brush body 1 are balanced when it is stuck together, preventing the brush body 1 from scraping away dirt or sticking to hair.

[0040] like Figure 3As shown, in this embodiment, the first magnet group is located at the other end of the first brush body 1. The control system is adapted to reduce the magnetism of the first magnet 2 when the first brush body 1 rotates to a preset position, so that the first brush body 1 rises and achieves a separation state. By setting the first magnet group at the other end of the first brush body 1, the first brush body 1 will be subjected to a downward driving force because the two magnets of the first magnet group have opposite polarities. And because the two magnets of the second magnet group also have opposite polarities, the first brush body 1 will be subjected to an upward buoyancy force. When the control system controls the magnetism of the first magnet 2 so that the magnetic force on the first brush body 1 is balanced, the first brush body 1 is in a suspended state. When the control system reduces the magnetism of the first magnet 2, breaking the force balance of the first brush body 1, the first brush body 1 will rise and achieve separation from the dirt.

[0041] like Figure 3 As shown, the housing in this embodiment includes: a first housing 6, on which a first magnet 2 is fixedly connected; and a second housing 7, spaced below the first housing 6, on which a second magnet 3 is fixedly connected, the second magnet 3 being disposed at the other end of the first brush body 1, the other end of the first brush body 1 pointing to... Figure 3 The upper end of the first brush body 1; the third shell 8, spaced below the second shell 7, and the fourth magnet 5 is fixedly connected to the third shell 8; the second shell 7 and the third shell 8 are provided with mounting holes, the first brush body 1 is provided in the mounting holes, and the third magnet 4 is fixedly connected to the first brush body 1 and located between the second shell 7 and the third shell 8.

[0042] The housing includes a fourth support member 12, with a second magnet 3 at its upper end and its lower end located inside the upper end of the first brush body 1. The fourth support member 12 can be fixed to the first brush body 1 by hooks or screws.

[0043] The housing includes a first support member 9, which is sleeved on the outside of the first brush body 1. A support flange is provided on the outer peripheral wall of the first support member 9. A third magnet 4 is provided at the upper end of the support flange, and a fourth magnet 5 is provided at the lower end of the support flange.

[0044] The height difference between the separated and adhered states of the first brush body 1 is 3mm-6mm. Alternatively, the height difference between the separated and adhered states of the first brush body 1 can be other values, which can be set according to actual needs; no further restrictions are imposed here.

[0045] To facilitate control and adjustment of the magnetic strength of the first magnet 2, in this embodiment, the first magnet 2 is an electromagnet; the second magnet 3, the third magnet 4, and the fourth magnet 5 are permanent magnets. As an alternative implementation, the second magnet 3, the third magnet 4, and the fourth magnet 5 may also be electromagnets, or some may be electromagnets and some may be permanent magnets.

[0046] In one embodiment, the rotary brush assembly includes at least two second magnetic components, which are magnetic. Each second magnetic component corresponds one-to-one with a first brush body 1 and a second brush body 18. The second magnetic components are fixedly connected to the housing and radially positioned outside the first brush body 1 and the second brush body 18, suitable for providing radial force to the first brush body 1 and the second brush body 18. By providing the second magnetic components, the second magnetic components provide radial force to the first brush body 1 and the second brush body 18. The cooperation between the second and first magnetic components allows the first and second brush bodies 1 and 18 to be in a suspended state, facilitating adjustment of their lifting and lowering. Furthermore, the second magnetic components ensure that the first and second brush bodies 1 and 18 are radially positioned at the center of the mounting hole and will not shift due to rotation, ensuring the normal use of the rotary brush.

[0047] Since the cross-section of the rotating brush mounting hole in this embodiment is circular, by setting the second magnetic component, it can be ensured that the first brush body 1 and the second brush body 18 are at the radial center of the mounting hole. The first magnetic component can ensure that the first brush body 1 and the second brush body 18 are at the circumferential position of the mounting hole. The second magnetic component cooperates with the first magnetic component to make the first brush body 1 and the second brush body 18 suspend in a suspended state.

[0048] Since the second magnetic component has the same configuration relationship as the first brush body 1 and the second brush body 18, the following description will take the configuration relationship between the second magnetic component and the first brush body 1 as an example.

[0049] The second magnetic component includes two third magnet groups located on the outer side of the first brush body 1. One of the two third magnet groups is located at the upper end of the first brush body 1, and the other is located near the lower end of the first brush body 1. Each third magnet group includes a fifth magnet 13 and a sixth magnet 14 arranged radially, with the magnetic properties of adjacent sides of the fifth magnet 13 and the sixth magnet 14 being opposite. By providing two third magnet groups, located at both ends of the first brush body 1, the rotary brush can be positioned at the center of the mounting hole along its overall axial direction, ensuring smooth rotation of the rotary brush. As an alternative implementation, the second magnetic component may include one third magnet group, which can be located in the middle of the first brush body 1 to ensure smooth rotation of the rotary brush.

[0050] Specifically, the fifth magnet 13 and the sixth magnet 14 are permanent magnets. As an alternative implementation, the fifth magnet 13 and the sixth magnet 14 may also be electromagnets, or one may be a permanent magnet and the other an electromagnet.

[0051] like Figure 3 As shown, the housing includes a third support member 11, which is sleeved on the outer side of the upper end of the first brush body 1. The third support member 11 and the second housing 7 form a space for accommodating the third magnet assembly located at the upper end.

[0052] The inner side of the third shell 8 is provided with an assembly flange, the upper end of which is provided with a fourth magnet, and the lower end of which is provided with a third magnet group located near the lower end of the first brush body 1.

[0053] The first driving component in this embodiment includes a seventh magnet 15 and an eighth magnet 16 arranged radially. The seventh magnet 15 is electrically connected and adapted to drive the first brush body 1 and the second brush body 18 to rotate. The seventh magnet 15 is an electromagnet, and the eighth magnet 16 is a permanent magnet. Alternatively, the eighth magnet 16 can also be an electromagnet. The driving component in this embodiment operates on the principle of a motor; through the interaction of the seventh magnet 15 and the eighth magnet 16, when the seventh magnet 15 is energized, the first brush body 1 and the second brush body 18 can rotate.

[0054] like Figure 3 As shown, the housing includes a second support member 10, which is sleeved on the outside of the first brush body 1 and the second brush body 18. The second support member 10 is located between the first support member 9 and the third support member 11, and is positioned above the first support member 9 and below the third support member 11. The second support member 10 and the second housing 7 form an accommodating space for the first drive assembly.

[0055] In this embodiment, the first shell 6, the second shell 7, the third shell 8, the first support member 9, the second support member 10, the third support member 11, and the fourth support member 12 are all made of non-magnetic material, specifically plastic. The magnetic components are sleeved on the outside of the first brush body 1 and the second brush body 18 and on the support members, and can be fixedly connected by screws.

[0056] Since the scraping device 101 on the first brush body 1 and the second brush body 18 has the same structure, the following description will take the scraping device 101 on the first brush body 1 as an example.

[0057] The shaving device 101 in this embodiment includes a shaving part 1011, disposed at the end of the first brush body 1. The end of the first brush body 1 has a rotation center, and the shaving part 1011 is disposed on one side of the rotation center. The shaving part 1011 is a rubber blade. By disposing the shaving part 1011 on one side of the end of the first brush body 1, the shaving part 1011 can only sweep hair in one direction when shaving hair, preventing the shaving parts 1011 on both sides from sweeping hair during rotation, which would cause the hair to clump together and be difficult to clean. Alternatively, the shaving device 101 can have shaving parts 1011 on both sides. However, in this case, both sides of the shaving parts 1011 will scrape hair, and when the first brush body 1 rotates, the hair on both sides will rotate simultaneously, easily tangling and clumping together.

[0058] The shaving device 101 in this embodiment includes a counterweight 1012, located on the other side of the rotation center. The weight of the counterweight 1012 is the same as the weight of the shaving part 1011, and the height of the counterweight 1012 is less than the height of the shaving part 1011. By placing the counterweight 1012 on the other side of the first brush body 1, and ensuring that its weight is the same as the weight of the shaving part 1011, the counterweight 1012 and the shaving part 1011 work together to balance the first brush body 1, preventing it from shaking during rotation. Furthermore, because the height of the counterweight 1012 is less than the height of the shaving part 1011, the counterweight 1012 does not come into contact with the hair when the shaving part 1011 scrapes it, preventing the hair from tangling.

[0059] Since the counterweight 1012 and the scraping part 1011 have the same weight, and the height of the counterweight 1012 is lower than the height of the scraping part 1011, the width of the counterweight 1012 is greater than the width of the scraping part 1011. Figure 5 As shown.

[0060] To prevent the placement unit from sweeping up hair and causing it to clump together on the floor, the height difference between the counterweight 1012 and the scraping unit 1011 can be set to 3.5mm-8mm. As an alternative implementation, the height difference between the placement unit and the scraping unit 1011 can be set to other data ranges, and no further restrictions are imposed here.

[0061] like Figures 6-8 As shown, according to an embodiment of the present invention, in another aspect, a floor scrubber brush is also provided, comprising: The bottom shell 17 is provided with a through hole 170 and a suction port 171. The through hole 170 is provided in a one-to-one correspondence with the mounting hole, and the suction port 171 is located on one side of the scraping device 101. The aforementioned rotary brush assembly has the rotary brush positioned at the through hole 170.

[0062] A third shell 8 is fixedly connected to the bottom shell 17, and the bottom shell 17 and the third shell 8 form a space for accommodating the third magnet assembly located near the lower end of the first brush body 1 and the second brush body 18.

[0063] like Figure 6 As shown, the suction port 171 is located in the middle of the bottom shell 17, and its general design dimensions are 30mm~50mm in length and 15mm~20mm in width. As an alternative implementation, the length of the suction port 171 can be increased, extending the suction port 171 to both sides of the bottom shell 17. In this case, the suction force at both ends of the extended suction port 171 will be greater.

[0064] In this embodiment, the floor scrubber brush has a rotating brush that rotates in two stages. In the first half of the rotation, the scraping part 1011 sweeps the hair from one position to another. In the second half of the rotation, the rotating brush rises rapidly by a distance. Due to inertia, the hair is thrown away from the scraping part 1011, thus solving the problem of hair getting tangled in the floor scrubber brush.

[0065] like Figure 8 As shown, the floor scrubber brush in this embodiment includes two sets of rotating brushes, comprising four brush bodies from left to right: A, B, C, and D. Brush bodies A and D are the first brush bodies 1, and brush bodies B and C are the second brush bodies 18. The four brush bodies rotate synchronously, and can form a relay effect on both sides of the suction port 171, effectively scraping away hair and other dirt far from the suction port 171 to the suction port 171 near the center through the relay action of the rotating brushes. Thus, hair and other dirt can be easily sucked away by the suction port 171.

[0066] Brush bodies A and B rotate clockwise, while brush bodies C and D rotate counterclockwise. The two outermost brush bodies 1 (A and D) sweep hair, dust, and other dirt from the floor towards the center. When the scraping parts 1011 of these two brush bodies 1 rotate to their respective positions ②, the magnetism of the first magnet 2 on the brush body 1 is reduced, causing the two brush bodies 1 to rise and the scraping parts 1011 to remove hair. At this time, the scraping parts 1011 of the two second brush bodies 18 (B and C) are precisely controlled to rotate to their respective positions ①, and the second brush bodies 18 are then controlled... The magnetism of the first magnet 2 increases, causing the two second brush bodies 18 to descend. Since the two second brush bodies 18 are tilted, they can catch the hair and other dirt dislodged by the two first brush bodies 1 (A and D), achieving a relay effect on the dirt from brush bodies A and D. This transfers the dirt towards the center of the floor scrubber near the suction inlet 171. The two second brush bodies 18 continue to rotate, thus sucking the hair and other dirt from the suction inlet 171 into the wastewater tank of the floor scrubber. The four brush bodies continue to rotate, creating a cycle that achieves relay cleaning of hair and other dirt, preventing hair from becoming tangled.

[0067] According to an embodiment of the present invention, in a third aspect, a floor scrubbing machine is also provided, comprising: the floor scrubbing machine brush described above.

[0068] Although embodiments of the invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the invention, and such modifications and variations all fall within the scope defined by the appended claims.
