Description

Technical Field

[0001] This invention relates to the field of household appliance technology, and in particular to a cleaning component and cleaning device. Background Technology

[0002] With the improvement of living standards, various time-saving and labor-saving cleaning equipment (such as robot vacuum cleaners, mopping machines, floor scrubbers, etc.) are gradually being widely used.

[0003] In related technologies, after the roller brush of the cleaning equipment comes into contact with the ground, the brush will stick tightly to the roller, resulting in a reduction in the contact interference between the roller brush and the ground, and a decrease in cleaning ability. Summary of the Invention

[0004] The main objective of this invention is to provide a cleaning component and cleaning equipment that ensures the contact interference between the roller brush and the ground to guarantee the cleaning capability of the cleaning equipment.

[0005] To achieve the above objectives, the present invention provides a cleaning component comprising:

[0006] Cover;

[0007] A roller brush is rotatably mounted on the cover.

[0008] A bristle mechanism is rotatably disposed on the cover, the rotation direction of the bristle mechanism is opposite to the rotation direction of the roller brush, and the linear velocity of at least two points of the bristle mechanism in contact with the roller brush is greater than the linear velocity of the roller brush.

[0009] In one embodiment, the ratio of the linear velocity of at least two points where the bristle mechanism contacts the roller brush to the linear velocity of the roller brush is 1.5 to 10.

[0010] In one embodiment, the length of the brush is defined as L, and the interference fit between the bristle mechanism and the brush is 30%L to 70%L.

[0011] In one embodiment, the bristle mechanism includes:

[0012] A rotating shaft extends along the axial direction of the roller brush;

[0013] Multiple comb teeth are spaced apart on the outer periphery of the rotating shaft, and the linear velocity of at least two of the comb teeth is greater than the linear velocity of the roller brush.

[0014] In one embodiment, a plurality of the comb teeth extend axially or spirally along the shaft to form a comb tooth group.

[0015] In one embodiment, the comb teeth are provided in at least two groups, and the at least two groups of comb teeth are distributed circumferentially along the axis of rotation.

[0016] In one embodiment, the cleaning assembly further includes a scraper disposed on the rotating shaft or the cover, for scraping the bristles on the roller brush.

[0017] In one embodiment, when the scraper is located on the rotating shaft, the scraper scrapes the bristles on the roller brush as the brush mechanism and the roller brush rotate.

[0018] In one embodiment, the scraper extends axially or spirally along the shaft.

[0019] In one embodiment, when the scraper is disposed on the cover, the scraper scrapes the bristles on the roller brush as the roller brush rotates.

[0020] In one embodiment, the cover is provided with a water spray nozzle, which is positioned toward the bristles of the roller brush, and the bristle mechanism and the water spray nozzle are distributed sequentially along the rotation direction of the roller brush.

[0021] In one embodiment, the bristle mechanism is connected to the roller brush via a transmission mechanism, and when the roller brush rotates, the transmission mechanism drives the bristle mechanism to rotate.

[0022] To achieve the above objectives, the present invention also provides a cleaning device comprising the cleaning components described above.

[0023] The technical solution of this invention involves providing a rotatable bristle mechanism on the cover. The rotation direction of the bristle mechanism is opposite to that of the roller brush, and the linear velocity of at least two points where the bristle mechanism contacts the roller brush is greater than the linear velocity of the roller brush. Thus, the rotation of the bristle mechanism and the roller brush loosens the bristles on the roller brush, preventing them from sticking tightly to the roller. This maintains a loose state during operation, effectively ensuring the contact interference between the roller brush and the ground, thereby effectively guaranteeing the cleaning capability of the cleaning equipment.

[0024] In addition, the brush is kept loose by the combing mechanism, so that it can absorb more water and transfer it to the ground before water is sprayed onto the roller brush. This improves water utilization, reduces water consumption, and extends the battery life.

[0025] Furthermore, when drying fluffy brushes, hot air can penetrate the brush interior more effectively, reducing the drying time of the roller brush and saving energy. Attached Figure Description

[0040] With the improvement of living standards, various time-saving and labor-saving cleaning equipment (such as robot vacuum cleaners, mopping machines, floor scrubbers, etc.) are gradually being widely used.

[0041] In related technologies, after the roller brush of the cleaning equipment comes into contact with the ground, the brush will stick tightly to the roller, resulting in a reduction in the contact interference between the roller brush and the ground, and a decrease in cleaning ability.

[0042] To address the aforementioned issues, this invention proposes a cleaning component 100 designed to ensure sufficient interference fit between the roller brush 20 and the ground, thereby guaranteeing the cleaning capability of the cleaning equipment 1000. The cleaning component 100 is applied in the cleaning equipment 1000, which can be a robotic vacuum cleaner, mop, floor scrubber, or similar device. The cleaning equipment 1000 may further include a dirt collection channel 200, located on one side of the cover 10, with its collection port facing the roller brush 20. During operation, the roller brush 20 uses friction with the ground to transfer dirt from the ground to the collection port. Finally, the negative pressure at the collection port transfers the dirt into the collection channel 200 for collection. The structure of the cleaning component 100 will be described below using embodiments:

[0043] Please see Figures 1 to 5In one embodiment of the present invention, the cleaning assembly 100 includes a cover 10, a roller brush 20, and a bristle mechanism 30; the roller brush 20 is rotatably disposed on the cover 10; the bristle mechanism 30 is rotatably disposed on the cover 10, the rotation direction of the bristle mechanism 30 is opposite to the rotation direction of the roller brush 20, the linear velocity of at least two points where the bristle mechanism 30 contacts the roller brush 20 is greater than the linear velocity of the roller brush 20, and when the bristle mechanism 30 and the roller brush 20 rotate, the bristle mechanism 30 loosens the bristles 21 on the roller brush 20.

[0044] Understandably, the cover 10 is dome-shaped and is used to fix and support the roller brush 20, the bristle mechanism 30, and other structures. The roller brush 20 is partially installed inside the cover 10 and partially extends to the bottom of the cover 10 so that it can rub against the ground when rotating. The bristle mechanism 30 is installed inside the cover 10 and is interference-fitted with the bristles 21 of the roller brush 20. This allows the bristle mechanism 30 to loosen the bristles 21 on the roller brush 20 when the brush mechanism 30 and the roller brush 20 are rotating, so that the bristles 21 are always kept fluffy.

[0045] In this embodiment, a drive module is also provided on the cover 10. The roller brush 20 is connected to the drive module so that the roller brush 20 can be driven to rotate. The drive module can also precisely control the rotation speed of the roller brush 20 to adjust the speed ratio between the roller brush 20 and the bristle mechanism 30.

[0046] The roller brush 20 may include a roller 22 and a brush 21. The brush 21 is disposed on the outer periphery of the roller 22. The roller 22 is driven by a drive module, which can drive the roller 22 and the brush 21 to rotate. Specifically, the brush 21 can be connected to the outer periphery of the roller 22 by means of pressing, injection molding, bonding, adsorption, or binding to ensure the reliability of the installation of the brush 21 and the roller 22 and to prevent the brush 21 from falling off the roller 22 during operation, thus affecting the cleaning effect.

[0047] In practical applications, the drive module can be a rotary motor, a motor with one or more gears (equivalent to a motor with a reducer), or a motor with a synchronous belt, as long as it can accurately control the rotation of the roller brush 20. No specific limitations are made here.

[0048] In one embodiment, when the drive module is a rotary motor, a mounting groove can be provided on the end face of the roller 22, and the output shaft of the rotary motor can be directly inserted into the mounting groove of the roller 22. When the rotary motor is working, it can directly drive the roller brush 20 to rotate through the output shaft.

[0049] In another embodiment, when the drive module is a structure in which a motor and one or more gears cooperate, a mounting shaft can be provided on the end face of the roller 22, and a mating tooth can be provided on the outer periphery of the mounting shaft. A gear is sleeved on the output shaft of the motor. The gear can directly mesh with the mating tooth of the mounting shaft, or it can mesh with the mating tooth of the mounting shaft through other gears. When the motor is working, it can drive the roller brush 20 to rotate through one or more gears.

[0050] In practical applications, the drive module can be located inside the roller 22 or outside the roller 22.

[0051] In one embodiment, the roller 22 may have a hollow cavity inside, so that the drive module can be placed in the hollow cavity of the roller 22. This makes use of the space inside the roller 22, making the overall structure more compact and reducing the size of the cleaning device 1000.

[0052] In another embodiment, the drive module can be located on one side of the roller 22, which makes it easier to install and maintain the drive module.

[0053] In practical applications, the roller brush 20 and the bristle mechanism 30 can be driven by the same set of drive modules, or they can be driven by two separate sets of drive modules.

[0054] It should be noted that the linear velocity of at least two points where the bristle mechanism 30 contacts the roller brush 20 is greater than the linear velocity of the roller brush 20 means that during the rotation of the bristle mechanism 30 and the roller brush 20, the bristle mechanism 30 will have at least two contact points that come into contact with the bristles 21 on the roller brush 20, and the linear velocity of at least two contact points will be greater than the linear velocity of the roller brush 20.

[0055] In summary, the technical solution of the present invention provides a rotatable bristle mechanism 30 on the cover 10. The rotation direction of the bristle mechanism 30 is opposite to that of the roller brush 20, and the linear velocity of at least two points where the bristle mechanism 30 contacts the roller brush 20 is greater than the linear velocity of the roller brush 20. Thus, with the rotation of the bristle mechanism 30 and the roller brush 20, the bristle mechanism 30 loosens the bristles 21 on the roller brush 20, preventing the bristles 21 from sticking tightly to the roller 22 of the roller brush 20. This maintains a loose state during operation, effectively ensuring the contact interference between the roller brush 20 and the ground, thereby effectively guaranteeing the cleaning capability of the cleaning equipment 1000.

[0056] In addition, because the combing mechanism keeps the brush 21 in a loose state at all times, the brush 21 can be in a fluffy state before spraying water onto the roller brush 20, so that the brush 21 can absorb more clean water and transfer it to the ground, thereby improving the utilization rate of clean water, reducing water consumption, and enhancing the battery life.

[0057] Furthermore, when drying the fluffy brush 21, hot air can better penetrate the interior of the brush 21, which can reduce the drying time of the roller brush 20 and save energy.

[0058] It should be noted that if the ratio of the linear velocity of at least two points where the bristle mechanism 30 contacts the roller brush 20 to the linear velocity of the roller brush 20 is too small, the bristle mechanism 30 will not have enough time to loosen the bristles 21 on the roller brush 20, and cannot ensure that the bristles 21 on the roller brush 20 are always in a fluffy state. On the other hand, if the ratio of the linear velocity of at least two points where the bristle mechanism 30 contacts the roller brush 20 to the linear velocity of the roller brush 20 is too large, the rotation speed of the bristle mechanism 30 will be too fast, which will cause some bristles 21 to not be loosened, thus failing to loosen the bristles 21 at various positions on the roller brush 20, and similarly failing to ensure that the bristles 21 on the roller brush 20 are always in a fluffy state.

[0059] Based on this, please refer to Figure 1 , Figure 2 In one embodiment of the present invention, the ratio of the linear velocity of at least two points where the bristle mechanism 30 contacts the roller brush 20 to the linear velocity of the roller brush 20 is 1.5 to 10.

[0060] With this configuration, by controlling the ratio of the linear velocity of at least two points where the bristle mechanism 30 contacts the roller brush 20 to the linear velocity of the roller brush 20 between 1.5 and 10, the bristle mechanism 30 can fully loosen the bristles 21 at various positions on the roller brush 20, effectively ensuring that the bristles 21 on the roller brush 20 are always kept in a fluffy state.

[0061] As examples, the ratio of the linear velocity of at least two points where the bristle mechanism 30 contacts the roller brush 20 to the linear velocity of the roller brush 20 can specifically be 1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5, 5.5, 6, 6.5, 7, 7.5, 8, 8.5, 9, 9.5, 10, etc.

[0062] It should be noted that if the interference fit between the bristle mechanism 30 and the brush 21 is too large, the distance between the bristle mechanism 30 and the roller 22 of the roller brush 20 will be too close. This will cause the bristle mechanism 30 to collide with the roller 22 when vibration occurs during operation, resulting in loud noise and even damage to the bristle mechanism 30. On the other hand, if the interference fit between the bristle mechanism 30 and the brush 21 is too small, the bristle mechanism 30 cannot fully loosen the brush 21, and cannot guarantee the contact interference fit between the roller brush 20 and the ground, thus reducing the cleaning ability of the cleaning equipment 1000.

[0063] Based on this, please refer to Figure 6 , Figure 7In one embodiment of the present invention, the length of the brush 21 is defined as L, and the interference fit between the brush mechanism 30 and the brush 21 is 30%L to 70%L.

[0064] By controlling the interference fit between the bristle mechanism 30 and the brush 21 between 30%L and 70%L, this configuration avoids generating excessive noise or even damaging the bristle mechanism 30, while ensuring that the brush 21 is sufficiently loosened to guarantee the interference fit between the roller brush 20 and the ground, thereby ensuring the cleaning capability of the cleaning equipment 1000.

[0065] As some examples, the interference fit between the bristle mechanism 30 and the brush 21 can be 30%L, 32%L, 35%L, 38%L, 40%L, 42%L, 45%L, 48%L, 50%L, 52%L, 55%L, 58%L, 60%L, 62%L, 65%L, 68%L, 70%L, etc.

[0066] Please see Figure 3 In one embodiment of the present invention, the brush mechanism 30 includes a rotating shaft 31 and a plurality of comb teeth 32; the rotating shaft 31 extends along the axial direction of the roller brush 20; the plurality of comb teeth 32 are spaced apart on the outer periphery of the rotating shaft 31, and the linear velocity of at least two comb teeth 32 is greater than the linear velocity of the roller brush 20.

[0067] With this configuration, by extending the shaft 31 of the bristle mechanism 30 along the axial direction of the roller brush 20, and distributing multiple comb teeth 32 at intervals on the outer periphery of the shaft 31, the comb teeth 32 can be rotated by the rotation of the shaft 31, thereby loosening the bristles 21 on the roller brush 20 and improving the loosening effect on the bristles 21.

[0068] In practical applications, the comb teeth 32 can be fixedly connected to the outer periphery of the rotating shaft 31 by means of pressing, injection molding, bonding, or plugging to ensure the installation reliability of the comb teeth 32 and the rotating shaft 31, and to prevent the comb teeth 32 from falling off the rotating shaft 31 during the loosening of the brush 21, thus affecting the loosening effect on the brush 21.

[0069] Furthermore, the comb teeth 32 can be soft parts, such as rubber parts, silicone parts, or other structural parts; or the comb teeth 32 can also be hard parts, such as plastic parts, metal parts, or other structural parts, as long as they can loosen the brush 21 when rotating, and no specific limitation is made here.

[0070] Furthermore, multiple comb teeth 32 can be distributed at intervals along the axial direction of the rotating shaft 31, or at intervals along the circumferential direction of the rotating shaft 31, or multiple comb teeth 32 can be distributed at intervals in both the axial and circumferential directions of the rotating shaft 31, or they can be arranged on the outer circumferential side of the rotating shaft 31 in a specific manner.

[0071] Furthermore, the spacing between any two adjacent comb teeth 32 can be the same or different. That is, multiple comb teeth 32 can be evenly distributed on the outer periphery of the rotating shaft 31, or they can be distributed on the outer periphery of the rotating shaft 31 in a specific arrangement.

[0072] Please see Figure 3 In one embodiment of the present invention, a plurality of comb teeth 32 extend axially or spirally along the rotating shaft 31 to form a comb tooth group.

[0073] With this configuration, since the bristles 21 on the roller brush 20 are evenly distributed on the outer periphery of the roller 22, by extending multiple gears axially or spirally along the shaft 31, the rotation of the brush mechanism 30 and the roller brush 20 ensures that the bristles 21 at each position on the roller brush 20 can be combed by the comb teeth 32, keeping the bristles 21 in each position fluffy at all times. Specifically, when the multiple comb teeth 32 spirally extend axially along the shaft 31, they can contact the bristles 21 on the roller brush 20 sequentially, exerting a squeezing effect on the bristles 21 in one direction, thus better loosening the bristles 21.

[0074] Of course, in other embodiments, the multiple comb teeth 32 can also extend in a wavy or sawtooth shape along the axial direction of the rotating shaft 31. Similarly, under the rotation of the brush mechanism 30 and the roller brush 20, the bristles 21 at each position on the roller brush 20 can be combed by the comb teeth 32, so that the bristles 21 at each position can always be kept fluffy.

[0075] In practical applications, the comb tooth group formed by multiple comb teeth 32 can be provided on the outer periphery of the rotating shaft 31, or at least two groups can be provided, depending on the actual use.

[0076] Please see Figure 3 In one embodiment of the present invention, the comb teeth are provided in at least two groups, and the at least two groups of comb teeth are distributed circumferentially along the rotating shaft 31.

[0077] With this configuration, at least two sets of comb teeth are spaced apart in the circumferential direction of the rotating shaft 31. Under the rotation of the bristle mechanism 30 and the roller brush 20, the frequency of the comb teeth 32 loosening the bristles 21 on the roller brush 20 can be increased. This means that when the bristle mechanism 30 rotates once, the bristles 21 on the roller brush 20 can be loosened at least twice, thereby improving the loosening effect on the bristles 21.

[0078] In some embodiments, when the comb teeth extend spirally along the axial direction of the rotating shaft 31 and at least two sets of comb teeth are provided on the outer peripheral side of the rotating shaft 31, on the projection of one end face of the rotating shaft 31, some comb teeth 32 of the two adjacent sets of comb teeth overlap. In this way, when the brush mechanism 30 rotates, the brush 21 on the roller brush 20 is first loosened by one set of comb teeth. When the comb tooth 32 in the comb tooth set that is in contact with the brush 21 is about to detach the brush 21, the next set of comb teeth will then loosen the brush 21 on the roller brush 20. This can continuously loosen the brush 21 on the roller brush 20 and improve the loosening effect of the brush 21.

[0079] In practical applications, at least two sets of comb teeth can be arranged in a circular array along the central axis of the rotating shaft 31, or they can be arranged in a specific pattern. That is, the spacing between any two adjacent sets of comb teeth can be the same or different.

[0080] Please see Figures 4 to 7 In one embodiment of the present invention, the cleaning component 100 further includes a scraper 40, which is disposed on the rotating shaft 31 or the cover 10 and is used to scrape the brush 21 on the roller brush 20.

[0081] With this configuration, since the roller brush 20 will carry away the sewage on the ground when it comes into contact with the ground to clean it, or the clean water on the roller brush 20 will form sewage after contact with the ground, a scraper 40 is provided on the rotating shaft 31 or the cover 10. During the rotation of the roller brush 20 and the bristle mechanism 30, the scraper 40 can scrape the bristles 21 on the roller brush 20 to remove the sewage from the bristles 21. On the one hand, the sewage in the bristles 21 can be squeezed out in time, reducing the generation of odor in the roller brush 20. On the other hand, it can prevent the roller brush 20 from bringing the sewage back to the ground during the rotation, thus affecting the cleaning effect on the ground.

[0082] In this embodiment, the scraper 40 is interference-fitted with the brush 21 on the roller brush 20 to fully scrape the brush 21 on the roller brush 20.

[0083] In practical applications, the interference fit between the scraper 40 and the brush 21 on the roller brush 20 can be between 30% and 70% of the length of the brush 21. Specifically, the interference fit between the scraper 40 and the brush 21 on the roller brush 20 can be 30%, 32%, 35%, 38%, 40%, 42%, 45%, 48%, 50%, 52%, 55%, 58%, 60%, 62%, 65%, 68%, 70%, etc., of the length of the brush 21. In this way, the scraper 40 can be prevented from contacting the roller 22 of the roller brush 20, thus avoiding excessive noise or even damage to the scraper 40, while ensuring that the brush 21 is thoroughly scraped to guarantee the effective scraping of wastewater by the brush 21.

[0084] In practical applications, the scraper 40 can be fixedly installed on the rotating shaft 31 or the cover 10 by means of pressing, injection molding, bonding, screw connection, snap-fit, or plug-in to ensure the installation reliability of the scraper 40 and prevent the scraper 40 from falling off, which would affect the scraping effect of the roller brush 20 on sewage.

[0085] Furthermore, the scraper 40 can be a soft part, such as a rubber part, a silicone part, or a hard part, such as a plastic part, a metal part, or any part that can scrape the brush 21 under the rotation of the roller brush 20 to scrape off the wastewater from the roller brush 20. No specific limitation is made here.

[0086] Please see Figure 4 , Figure 5 , Figure 7 In one embodiment of the present invention, when the scraper 40 is disposed on the rotating shaft 31, the scraper 40 scrapes the brush 21 on the roller brush 20 under the rotation of the brush mechanism 30 and the roller brush 20.

[0087] With this configuration, when the scraper 40 is positioned on the rotating shaft 31, the scraper 40 will rotate together with the rotating shaft 31. Thus, under the rotation of the bristle mechanism 30 and the roller brush 20, when the comb teeth 32 on the bristle mechanism 30 come into contact with the bristles 21 on the roller brush 20, the comb teeth 32 can loosen the bristles 21. When the scraper 40 on the bristle mechanism 30 comes into contact with the bristles 21 on the roller brush 20, the scraper 40 can scrape the bristles 21 to squeeze out the dirty water in the bristles 21 in time, reducing the generation of odor in the roller brush 20. This allows the bristle mechanism 30 to simultaneously achieve the effects of loosening and scraping the bristles 21 while rotating.

[0088] In this embodiment, the scraper 40 is disposed on the outer peripheral side of the rotating shaft 31 and is distributed at intervals with the comb teeth in the circumferential direction of the rotating shaft 31, which can ensure the loosening and scraping cleaning effect on the brush 21.

[0089] In practical applications, one or at least two scrapers 40 can be provided on the outer periphery of the rotating shaft 31, depending on the actual usage.

[0090] In some embodiments, in order to improve the scraping effect of the scraper 40 on the brush 21, at least two scrapers 40 can be distributed at intervals around the circumference of the rotating shaft 31. With the rotation of the bristle mechanism 30 and the roller brush 20, the frequency of scraping the brush 21 on the roller brush 20 by the scraper 40 can be increased. This means that when the bristle mechanism 30 rotates once, the brush 21 on the roller brush 20 can be scraped at least twice, thereby improving the effect of scraping sewage from the brush 21.

[0091] Please see Figure 4 , Figure 5 In one embodiment of the present invention, the scraper 40 extends axially or spirally along the rotating shaft 31.

[0092] With this configuration, since the bristles 21 on the roller brush 20 are evenly distributed on the outer periphery of the roller 22, by extending the scraper 40 axially or spirally along the shaft 31, the rotation of the brush mechanism 30 and the roller brush 20 ensures that all the bristles 21 on the roller brush 20 can be scraped by the scraper 40, keeping all the bristles 21 dry. When the scraper 40 spirally extends axially along the shaft 31, it contacts the bristles 21 on the roller brush 20 sequentially, creating a squeezing effect on the bristles 21 in one direction, thus better squeezing out wastewater. Simultaneously, the spirally extended scraper 40 can scrape the wastewater off the bristles 21 and guide it into the collection channel 200, improving the wastewater collection efficiency.

[0093] Of course, in other embodiments, the scraper 40 can also extend in a wavy or serrated shape along the axial direction of the rotating shaft 31. Similarly, under the rotation of the brush mechanism 30 and the roller brush 20, the scraper 40 can scrape the brushes 21 at each position on the roller brush 20 to squeeze out the sewage in the brushes 21 in time, so that the brushes 21 at each position can be kept dry and the generation of odor in the roller brush 20 is reduced.

[0094] Please see Figure 6 In another embodiment of the present invention, when the scraper 40 is provided on the cover 10, the scraper 40 scrapes the brush 21 on the roller brush 20 under the rotation of the roller brush 20.

[0095] With this configuration, when the scraper 40 is placed on the cover 10, the scraper 40 is fixed relative to the cover 10. In this way, when the roller brush 20 rotates, when the scraper 40 comes into contact with the brush 21 on the roller brush 20, the scraper 40 can scrape the brush 21, which can effectively scrape off the sewage on the brush 21 and squeeze out the sewage in the brush 21 in time, thereby reducing the generation of odor in the roller brush 20.

[0096] In practical applications, one or at least two scrapers 40 can be provided on the cover 10, depending on the actual usage. When at least two scrapers 40 are provided on the cover 10, the scrapers 40 can be distributed sequentially along the rotation direction of the roller brush 20. This allows the brush 21 to be scraped sequentially by the scrapers 40 as the roller brush 20 rotates, so that the sewage in the brush 21 can be squeezed out in time and fully, thereby improving the scraping effect on the brush 21 and further reducing the generation of odor in the roller brush 20.

[0097] Please see Figure 6 , Figure 7In one embodiment of the present invention, the cover 10 is provided with a water spray nozzle 11, which is positioned toward the brush 21 of the roller brush 20. The brush bristle mechanism 30 and the water spray nozzle 11 are distributed sequentially along the rotation direction of the roller brush 20.

[0098] This configuration, by directing the water nozzle 11 toward the roller brush 20, introduces the technology of live water cleaning. When the roller brush 20 rotates to clean, clean water is sprayed onto the roller brush 20 through the water nozzle 11. The brushes 21 on the roller brush 20 have a good ability to absorb water. When the roller brush 20 rotates, it can carry clean water to clean the ground. After cleaning the ground, the wastewater can be scraped off by the scraper 40 to separate the wastewater from the roller brush 20, thereby achieving the effect of live water cleaning.

[0099] In addition, by distributing the bristle mechanism 30 and the water nozzle 11 sequentially along the rotation direction of the roller brush 20, when the cover 10 is equipped with a scraper 40, the bristle mechanism 30 will be located between the scraper 40 and the water nozzle 11. This is equivalent to setting the working position of the bristle mechanism 30 before the process of spraying clean water. That is, after loosening the bristles 21 on the roller brush 20, clean water is sprayed onto the bristles 21. This allows the bristles 21 to be in a fluffy state before spraying water, which can allow the bristles 21 to absorb more clean water and transfer it to the ground, thereby improving the utilization rate of clean water, reducing water consumption, and extending the battery life.

[0100] In some embodiments, a nozzle may be provided on the cover 10. The nozzle has a water spray nozzle 11. The nozzle may be connected to an external water supply pipe. Clean water flows to the nozzle through the water supply pipe and is finally sprayed onto the roller brush 20 through the water spray nozzle 11.

[0101] Please see Figure 1 In one embodiment of the present invention, the bristle mechanism 30 is connected to the roller brush 20 through the transmission mechanism 50. When the roller brush 20 rotates, the transmission mechanism 50 drives the bristle mechanism 30 to rotate.

[0102] With this configuration, the rotation of the roller brush 20 can simultaneously drive the bristle mechanism 30 to rotate via the transmission mechanism 50. This way, only one set of drive modules is needed to achieve the rotation of both the roller brush 20 and the bristle mechanism 30, reducing the number of drive modules required and thus lowering costs.

[0103] It should be noted that the transmission mechanism 50 acts as a gearbox to adjust the speed ratio between the brushing mechanism 30 and the roller brush 20.

[0104] In practical applications, the transmission mechanism 50 can be a gear set or a structure that combines gears and a timing belt. As long as it can simultaneously drive the brush mechanism 30 to rotate and can adjust the speed ratio between the brush mechanism 30 and the roller brush 20, it is acceptable to ensure that the linear velocity of at least two points where the brush mechanism 30 and the roller brush 20 are in contact is greater than the linear velocity of the roller brush 20.

[0105] Please see Figure 1 In one embodiment of the present invention, the end of the roller brush 20 is provided with a connecting shaft 221, and the transmission mechanism 50 is a gear set, which includes a first gear 51, a second gear 52, a third gear 53 and a fourth gear 54; the first gear 51 is sleeved on the connecting shaft 221; the second gear 52 meshes with the first gear 51; the third gear 53 meshes with the second gear 52; the fourth gear 54 meshes with the third gear 53 and is sleeved on the rotating shaft 31 of the brush mechanism 30.

[0106] With this configuration, the rotation of the roller brush 20 can sequentially drive the first gear 51, the second gear 52, the third gear 53, and the fourth gear 54 to rotate, ultimately driving the bristle mechanism 30 to rotate. With the cooperation of the first gear 51, the second gear 52, the third gear 53, and the fourth gear 54, the transmission ratio of the gear set can be precisely adjusted, thereby precisely adjusting the speed ratio between the bristle mechanism 30 and the roller brush 20.

[0107] Please see Figure 2 In another embodiment of the present invention, the cleaning device 1000 further includes a drive mechanism 60, and the bristle mechanism 30 is tractively connected to the drive mechanism 60, and the drive mechanism 60 drives the bristle mechanism 30 to rotate.

[0108] With this configuration, by using an additional drive mechanism 60 to drive the bristle mechanism 30 to rotate independently, the rotation speed of the bristle mechanism 30 can be precisely controlled by adjusting the rotation speed of the drive mechanism 60. Similarly, the rotation speed ratio between the bristle mechanism 30 and the roller brush 20 can be adjusted to ensure that the linear velocity of at least two points where the bristle mechanism 30 and the roller brush 20 are in contact is greater than the linear velocity of the roller brush 20.

[0109] In practical applications, the drive mechanism 60 can be a rotary motor, a motor with one or more gears (equivalent to a motor with a reducer), or a motor with a synchronous belt, as long as it can accurately control the rotation of the brush mechanism 30. No specific limitations are made here.

[0110] Please see Figure 6 , Figure 7The present invention also proposes a cleaning device 1000, which includes a cleaning component 100. The specific structure of the cleaning component 100 is as described in the above embodiments. Since the cleaning device 1000 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0111] In this embodiment, the cleaning device 1000 may further include a dirt collection channel 200, which is located on one side of the cover 10, and the dirt collection port of the dirt collection channel 200 is facing the roller brush 20. In this way, during operation, the roller brush 20 uses friction with the ground to transfer dirt on the ground to the dirt collection port, and finally transfers the dirt into the dirt collection channel 200 through the negative pressure of the dirt collection port for dirt collection.

[0112] Of course, the cleaning equipment 1000 may also include a sludge collection box (not shown in the figure), which is connected to the sludge collection channel 200. Pollutants are collected into the sludge collection box through the sludge collection channel 200, and users can periodically remove the sludge collection box for cleaning.

[0113] Specifically, cleaning equipment 1000 can be equipment such as sweeping robots, mopping robots, and floor scrubbers.
