[0003] In the related art, after the roller brush of the cleaning equipment contacts the ground, the bristles of the brush will stick tightly to the roller, resulting in a reduction in the interference fit between the roller brush and the ground and a decrease in the cleaning ability. Utility Model Content

[0004] The main purpose of the utility model is to provide a cleaning component and a cleaning device, which are intended to ensure the interference fit between the roller brush and the ground, so as to ensure the cleaning ability of the cleaning device.

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

[0006] Cover body;

[0007] a roller brush rotatably disposed on the cover;

[0008] The bristle mechanism is rotatably provided on the cover body, 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 where the bristle mechanism contacts 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 1.5-10.

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

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

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

[0013] A plurality of comb teeth are distributed at intervals on the outer peripheral side of the rotating shaft, and the linear speed of at least two of the comb teeth is greater than the linear speed of the roller brush.

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

[0015] In one embodiment, there are at least two comb tooth groups, and the at least two comb tooth groups are spaced apart along the circumference of the rotating shaft.

[0016] In one embodiment, the cleaning assembly further includes a scraper, which is provided on the rotating shaft or the cover and is used to scrape the bristles on the roller brush.

[0017] In one embodiment, when the scraper is disposed 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 along the axial direction of the rotating shaft or extends in an axial spiral manner.

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

[0020] In one embodiment, the cover body is provided with a water spray port, the water spray port is arranged toward the bristle of the roller brush, and the bristle mechanism and the water spray port are distributed in sequence along the rotation direction of the roller brush.

[0022] To achieve the above objectives, the present invention further provides a cleaning device comprising the above cleaning assembly.

[0023] The technical solution of the utility model is to provide a rotatable bristle mechanism on the cover body. 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. In this way, as the bristle mechanism and the roller brush rotate, the bristles on the roller brush can be loosened by the bristle mechanism, so that the bristles do not cling tightly to the roller of the roller brush, thereby maintaining a loose state at all times during operation, effectively ensuring the interference fit between the roller brush and the ground, and thus effectively maintaining the cleaning ability of the cleaning device.

[0024] In addition, since the combing mechanism can keep the brush loose at all times, the brush can be in a fluffy state before spraying water onto the roller brush, so that the brush can absorb more clean water and transfer it to the ground, which can improve the utilization rate of clean water, reduce water consumption, and improve endurance.

[0025] Moreover, when drying the fluffy brush, the hot air can better enter the inside of the brush, which can reduce the drying time of the roller brush and save energy. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] With the improvement of living standards, various time-saving and labor-saving cleaning equipment (such as sweeping robots, mopping machines, floor washing machines, etc.) have gradually become widely used.

[0041] In the related art, after the roller brush of the cleaning equipment contacts the ground, the bristles of the brush will stick tightly to the roller, resulting in a reduction in the interference fit between the roller brush and the ground and a decrease in the cleaning ability.

[0042] Based on the above problems, the present invention proposes a cleaning component 100, which aims to ensure the interference fit between the roller brush 20 and the ground, so as to ensure the cleaning ability of the cleaning device 1000. The cleaning component 100 is applied to the cleaning device 1000, and the cleaning device 1000 can be a sweeping robot, a mopping machine, a floor scrubber and other equipment. The cleaning device 1000 can also include a sewage collection channel 200, which is provided on one side of the cover body 10, and the sewage collection port of the sewage collection channel 200 is arranged toward the roller brush 20. In this way, during operation, the roller brush 20 uses friction with the ground to transfer the dirt on the ground to the sewage collection port, and finally transfers the dirt to the sewage collection channel 200 through the negative pressure of the sewage collection port to collect the dirt. The structure of the cleaning component 100 will be described below in the form of an embodiment:

[0043] See also Figures 1 to 5In one embodiment of the present invention, the cleaning assembly 100 includes a cover body 10, a roller brush 20 and a bristle mechanism 30; the roller brush 20 is rotatably provided on the cover body 10; the bristle mechanism 30 is rotatably provided on the cover body 10, and 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. 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] As can be understood, the cover 10 is shaped like a hood 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 in the cover 10 and partially extends to the bottom of the cover 10 to frictionally contact the ground during rotation. The bristle mechanism 30 is installed in the cover 10 and has an interference fit with the bristles 21 of the roller brush 20. When the bristle mechanism 30 and the roller brush 20 rotate, the bristle mechanism 30 loosens the bristles 21 on the roller brush 20 through the bristle mechanism 30, so that the bristles 21 on the roller brush 20 are always kept fluffy.

[0045] In this embodiment, a driving module is also provided on the cover body 10, and the roller brush 20 is connected to the driving module through the driving module to drive the roller brush 20 to rotate, and the rotation speed of the roller brush 20 can be accurately controlled by the driving module to achieve the speed ratio adjustment of 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 transmission-connected to a drive module, which can drive the roller 22 and the brush 21 to rotate. Specifically, the brush 21 may be connected to the outer periphery of the roller 22 by means of crimping, injection molding, bonding, adsorption, bundling, etc., to ensure reliable installation of the brush 21 and the roller 22, and to prevent the brush 21 from falling off the roller 22 during operation, thereby affecting the cleaning effect.

[0047] In actual application, the driving module can be directly a rotating motor, or a structure in which a motor cooperates with one or more gears (equivalent to a structure in which a motor cooperates with a reducer), or a structure in which a motor cooperates with a synchronous belt. As long as the rotation of the roller brush 20 can be accurately controlled, no specific limitation is made here.

[0048] In one embodiment, when the driving module is a rotary motor, a mounting groove can be provided on the end surface 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, the roller brush 20 can be directly driven to rotate through the output shaft.

[0049] In another embodiment, when the driving module is a structure in which a motor cooperates with one or more gears, a mounting shaft can be provided on the end face of the roller 22, and mating teeth can be provided on the outer peripheral side of the mounting shaft. A gear is provided on the output shaft of the motor, and the gear can be directly engaged with the mating teeth of the mounting shaft, or can be engaged with the mating teeth of the mounting shaft through other gears. When the motor is working, the roller brush 20 can be driven to rotate through one or more gears.

[0050] In practical applications, the driving module can be disposed 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 disposed in the hollow cavity of the roller 22 . This allows the space inside the roller 22 to be utilized, making the overall structure more compact and reducing the volume of the cleaning device 1000 .

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

[0053] In actual application, the roller brush 20 and the bristle mechanism 30 can be driven by the same set of driving modules, or can be driven separately by two sets of driving 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, which 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 in contact with the brush 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 is to provide a rotatable bristle mechanism 30 on the cover body 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. In this way, under the rotation of the bristle mechanism 30 and the roller brush 20, the bristle mechanism 30 can loosen the bristles 21 on the roller brush 20, so that the bristles 21 will not be tightly attached to the roller 22 of the roller brush 20, so as to maintain a loose state at all times during operation, effectively ensuring the interference fit between the roller brush 20 and the ground, thereby effectively ensuring the cleaning ability of the cleaning device 1000.

[0056] In addition, since the brush 21 can be kept loose at all times under the action of the combing mechanism, 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, which can improve the utilization rate of clean water, reduce water consumption, and improve endurance.

[0057] Moreover, when drying the fluffy brush 21, hot air can better enter 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, since the ratio of the linear velocity of at least two points where the brush mechanism 30 contacts the roller brush 20 to the linear velocity of the roller brush 20 is too small, the brush mechanism 30 will not have time to loosen the bristles 21 on the roller brush 20, and it is impossible to ensure that the bristles 21 on the roller brush 20 always remain in a fluffy state; and since the ratio of the linear velocity of at least two points where the brush mechanism 30 contacts the roller brush 20 to the linear velocity of the roller brush 20 is too large, the rotation speed of the brush mechanism 30 is too fast, which will result in some of the bristles 21 not being loosened, thereby 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 always remain in a fluffy state.

[0059] Based on this, see 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 1.5-10.

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

[0061] As some 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 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, when 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. In this way, when vibration occurs during operation, the bristle mechanism 30 and the roller 22 will collide, generating loud noise and even damaging the bristle mechanism 30. However, when 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 ensure the interference fit between the roller brush 20 and the ground, which reduces the cleaning ability of the cleaning device 1000.

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

[0064] In this way, by controlling the interference fit between the brush mechanism 30 and the brush 21 to be between 30%L and 70%L, it is possible to avoid generating loud noise or even damaging the brush mechanism 30, while at the same time, the brush 21 can be sufficiently loosened to ensure the interference fit between the roller brush 20 and the ground, thereby ensuring the cleaning ability of the cleaning device 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 and so on.

[0066] See also Figure 3 In one embodiment of the present invention, the bristle 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 distributed at intervals on the outer peripheral side 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] In this arrangement, the rotating shaft 31 of the brush mechanism 30 extends along the axial direction of the roller brush 20, and a plurality of comb teeth 32 are spaced apart on the outer peripheral side of the rotating shaft 31. When the comb teeth 32 are rotated by the rotation of the rotating shaft 31, the bristles 21 on the roller brush 20 can be loosened by the plurality of comb teeth 32, thereby improving the loosening effect of the brush 21.

[0068] In actual application, the comb teeth 32 can be fixedly connected to the outer peripheral side of the rotating shaft 31 by crimping, injection molding, bonding, plugging, etc. to ensure the installation reliability of the comb teeth 32 and the rotating shaft 31, and avoid the comb teeth 32 falling off from the rotating shaft 31 during the loosening process of the brush 21, thereby affecting the loosening effect of the brush 21.

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

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

[0071] Furthermore, the spacing between any two adjacent comb teeth 32 may be the same or different, that is, the plurality of comb teeth 32 may be evenly distributed on the outer circumference of the rotating shaft 31 or may be distributed on the outer circumference of the rotating shaft 31 in a specific arrangement.

[0072] See also Figure 3 In one embodiment of the present invention, a plurality of comb teeth 32 extend along the axial direction of the rotating shaft 31 or extend axially in a spiral manner to form a comb tooth group.

[0073] With this arrangement, since the bristles 21 on the roller brush 20 are evenly distributed on the outer circumference of the roller 22, by extending the plurality of gears axially or spirally along the rotating shaft 31, the bristle mechanism 30 and the roller brush 20 rotate, so that the bristles 21 at various positions on the roller brush 20 can be combed by the comb teeth 32, so that the bristles 21 at various positions can be kept in a fluffy state at all times. Specifically, when the plurality of comb teeth 32 spirally extend along the axial direction of the rotating shaft 31, the plurality of comb teeth 32 can successively contact the bristles 21 on the roller brush 20, which can have a squeezing effect on the bristles 21 in one direction, thereby better loosening the bristles 21.

[0074] Of course, in other embodiments, the plurality of comb teeth 32 may also extend in a wavy, serrated, or other 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 brushes 21 at various positions on the roller brush 20 can be combed by the comb teeth 32, so that the brushes 21 at various positions can always be kept in a fluffy state.

[0075] In actual application, the comb teeth group formed by the plurality of comb teeth 32 may be provided with one group or at least two groups on the outer peripheral side of the rotating shaft 31 , and the specific amount may be determined according to actual usage.

[0076] See also Figure 3 In one embodiment of the present invention, there are at least two comb tooth groups, and the at least two comb tooth groups are spaced apart along the circumference of the rotating shaft 31.

[0077] In this way, by distributing at least two groups of comb teeth at intervals on the circumference of the rotating shaft 31, the frequency of the comb teeth 32 loosening the brush 21 on the roller brush 20 can be increased under the rotation of the brush mechanism 30 and the roller brush 20, which is equivalent to loosening the brush 21 on the roller brush 20 at least twice when the brush mechanism 30 rotates one circle, thereby improving the loosening effect of the brush 21.

[0078] In some embodiments, when the comb tooth group extends spirally along the axial direction of the rotating shaft 31 and at least two groups of comb tooth groups are arranged on the outer peripheral side of the rotating shaft 31, on the projection of one of the end faces of the rotating shaft 31, some comb teeth 32 in the two adjacent groups of comb tooth groups overlap. In this way, when the brush mechanism 30 rotates and rolls, the brush 21 on the roller brush 20 is first loosened by one of the groups of comb tooth groups. When the comb teeth 32 in the comb tooth group that are in contact with the brush 21 at the back are about to fall off the brush 21, the latter group of comb tooth groups will immediately loosen the brush 21 on the roller brush 20. In this way, the brush 21 on the roller brush 20 can be continuously loosened, which can improve the loosening effect of the brush 21.

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

[0080] See also Figures 4 to 7 In one embodiment of the present invention, the cleaning assembly 100 further includes a scraper 40 . The scraper 40 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] In this arrangement, since the roller brush 20 will take away the sewage on the ground when it is in friction contact with the ground to clean the ground, or the clean water on the roller brush 20 will form sewage after contacting the ground, a scraper 40 is provided on the rotating shaft 31 or the cover body 10. During the rotation of the roller brush 20 and the brush mechanism 30, the scraper 40 can be used to scrape the brush 21 on the roller brush 20 to scrape off the sewage on the brush 21. On the one hand, the sewage in the brush 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 sewage to the ground again during rotation, thereby affecting the cleaning effect of the ground.

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

[0083] In actual application, the interference between the scraper 40 and the brush 21 on the roller brush 20 may also be between 30% and 70% of the length of the brush 21. Specifically, the interference between the scraper 40 and the brush 21 on the roller brush 20 may also 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 to generate loud noise or even damage the scraper 40, while the brush 21 can be fully scraped to ensure the effect of scraping dirty water by the brush 21.

[0084] In actual application, the scraper 40 can be fixedly installed on the rotating shaft 31 or the cover body 10 by means of crimping, injection molding, bonding, screw connection, snap connection, plugging, etc., so as to ensure the installation reliability of the scraper 40 and avoid the scraper 40 from falling off, which affects the effect of scraping sewage by the roller brush 20.

[0085] Furthermore, the scraper 40 may be a soft part, such as a rubber part, a silicone part or other structural part; or, the scraper 40 may be a hard part, such as a plastic part, a metal part or other structural part. As long as it can scrape the brush 21 under the rotation of the roller brush 20 to scrape off the dirty water on the roller brush 20, no specific limitation is made here.

[0086] See also 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 as the brush mechanism 30 and the roller brush 20 rotate.

[0087] In this way, when the scraper 40 is set on the rotating shaft 31, the scraper 40 will rotate with the rotating shaft 31. In this way, under the rotation of the brush mechanism 30 and the roller brush 20, when the comb teeth 32 on the brush mechanism 30 contact the brush 21 on the roller brush 20, the brush 21 can be loosened by the comb teeth 32, and when the scraper 40 on the brush mechanism 30 contacts the brush 21 on the roller brush 20, the brush 21 can be scraped by the scraper 40 to squeeze out the sewage in the brush 21 in time, reducing the generation of odor in the roller brush 20, so that the brush mechanism 30 can simultaneously achieve the loosening and scraping cleaning effects of the brush 21 during rotation.

[0088] In this embodiment, the scraper 40 is provided on the outer peripheral side of the rotating shaft 31 and is spaced apart from the comb tooth group in the circumferential direction of the rotating shaft 31 , thereby ensuring the loosening and scraping cleaning effect on the brush 21 .

[0089] In actual application, one or at least two scrapers 40 may be provided on the outer circumference of the rotating shaft 31 , and the specific number may be determined according to 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 in the circumferential direction of the rotating shaft 31. When the brush mechanism 30 and the roller brush 20 rotate, the frequency of the scraper 40 scraping the brush 21 on the roller brush 20 can be increased, which is equivalent to scraping the brush 21 on the roller brush 20 at least twice when the brush mechanism 30 rotates one circle, thereby improving the effect of scraping dirty water by the brush 21.

[0091] See also 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 such a configuration, since the bristles 21 on the roller brush 20 are evenly distributed on the outer circumference of the roller 22, the scraper 40 can be extended axially or spirally along the rotating shaft 31. Under the rotation of the brush mechanism 30 and the roller brush 20, the bristles 21 at various positions on the roller brush 20 can be scraped by the scraper 40, so that the bristles 21 at various positions can be kept dry. Specifically, when the scraper 40 spirally extends along the axial direction of the rotating shaft 31, the scraper 40 can successively contact the bristles 21 on the roller brush 20, which can have a squeezing effect on the bristles 21 in one direction, thereby better squeezing out the sewage. At the same time, the sewage on the brush 21 can be scraped off by the spirally extended scraper 40, and the sewage can be directed into the sewage collection channel 200, thereby improving the sewage collection effect.

[0093] Of course, in other embodiments, the scraper 40 may also extend in a wavy, serrated, or other 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 brushes 21 at various positions on the roller brush 20 can be scraped by the scraper 40, so as to squeeze out the sewage in the brush 21 in time, so that the brushes 21 at various positions can be kept in a dry state, thereby reducing the generation of odor in the roller brush 20.

[0094] See also 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 as the roller brush 20 rotates.

[0095] In this arrangement, when the scraper 40 is set on the cover body 10, the scraper 40 is fixed relative to the cover body 10. In this way, when the roller brush 20 rotates, when the scraper 40 contacts the brush 21 on the roller brush 20, the brush 21 can be scraped by the scraper 40, which can effectively scrape off the sewage on the brush 21, so as to squeeze out the sewage in the brush 21 in time, thereby reducing the generation of odor in the roller brush 20.

[0096] In actual use, one or at least two scrapers 40 can be provided on the cover 10, depending on the actual use situation. When at least two scrapers 40 are provided on the cover 10, the at least two scrapers 40 can be distributed sequentially along the rotation direction of the roller brush 20. In this way, when the roller brush 20 rotates, the at least two scrapers 40 can sequentially scrape the brush 21, thereby timely and fully squeezing out the dirty water in the brush 21, thereby improving the scraping effect of the brush 21 and further reducing the generation of odor in the roller brush 20.

[0097] See also Figure 6 、 Figure 7 In one embodiment of the present invention, the cover body 10 is provided with a water spray port 11 , which is arranged toward the brush 21 of the roller brush 20 , and the brush mechanism 30 and the water spray port 11 are distributed in sequence along the rotation direction of the roller brush 20 .

[0098] In this way, by setting the water outlet 11 toward the roller brush 20, the technology of live water cleaning is introduced. When the roller brush 20 rotates for cleaning, clean water is sprayed onto the roller brush 20 through the water outlet 11. The brush 21 on the roller brush 20 has a good ability to absorb water. The roller brush 20 can carry clean water for cleaning the ground when rotating. After cleaning the ground, the scraper 40 can scrape off the dirty water to separate the dirty water from the roller brush 20 to achieve the effect of live water cleaning.

[0099] In addition, by distributing the brush mechanism 30 and the water outlet 11 in sequence along the rotation direction of the roller brush 20, when a scraper 40 is provided on the cover body 10, the brush mechanism 30 will be located between the scraper 40 and the water outlet 11, which is equivalent to setting the working position of the brush mechanism 30 before the process of spraying clean water, that is, first loosening the brush 21 on the roller brush 20, and then spraying clean water on the brush 21. In this way, the brush 21 can be in a fluffy state before spraying water, 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 improving endurance.

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

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

[0102] With such arrangement, when the roller brush 20 rotates, the bristle mechanism 30 can be driven to rotate simultaneously through the transmission mechanism 50. In this way, only one set of drive modules is needed to realize the rotation of the roller brush 20 and the bristle mechanism 30, which can reduce the number of drive modules used and achieve the purpose of reducing costs.

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

[0104] In actual application, the transmission mechanism 50 can be a gear set or a structure composed of gears and synchronous belts, as long as it can simultaneously drive the brush mechanism 30 to rotate and can adjust the speed ratio of the brush mechanism 30 and the roller brush 20 to ensure that the linear velocity of at least two points where the brush mechanism 30 contacts the roller brush 20 is greater than the linear velocity of the roller brush 20.

[0105] See also Figure 1 In one embodiment of the present invention, a connecting shaft 221 is provided at the end of the roller brush 20, 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 is engaged with the first gear 51; the third gear 53 is engaged with the second gear 52; the fourth gear 54 is engaged with the third gear 53, and is sleeved on the rotating shaft 31 of the bristle mechanism 30.

[0106] With such arrangement, when the roller brush 20 rotates, the first gear 51, the second gear 52, the third gear 53 and the fourth gear 54 can be driven to rotate in sequence, and finally the bristle mechanism 30 can be driven 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 accurately adjusted, and then the speed ratio of the bristle mechanism 30 and the roller brush 20 can be accurately adjusted.

[0107] See also Figure 2 In another embodiment of the present invention, the cleaning device 1000 further includes a driving mechanism 60 , the bristle mechanism 30 is transmission-connected to the driving mechanism 60 , and the driving mechanism 60 drives the bristle mechanism 30 to rotate.

[0108] With such a configuration, by using an additional driving mechanism 60 to independently drive the brush mechanism 30 to rotate, the rotational speed of the brush mechanism 30 can be precisely controlled by adjusting the rotational speed of the driving mechanism 60. The rotational speed ratio of the brush mechanism 30 and the roller brush 20 can also be adjusted to ensure that the linear velocity of at least two points where the brush mechanism 30 contacts the roller brush 20 is greater than the linear velocity of the roller brush 20.

[0109] In actual application, the driving mechanism 60 can be directly a rotating motor, or a structure in which a motor cooperates with one or more gears (equivalent to a structure in which a motor cooperates with a reducer), or a structure in which a motor cooperates with a synchronous belt. As long as the rotation of the brush mechanism 30 can be accurately controlled, no specific limitation is made here.

[0110] See also 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 refers to the above embodiment. Since the cleaning device 1000 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.

[0111] In this embodiment, the cleaning device 1000 may also include a dirt collecting channel 200, which is arranged on one side of the cover body 10, and the dirt collecting port of the dirt collecting channel 200 is arranged toward 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 collecting port, and finally transfers the dirt to the dirt collecting channel 200 through the negative pressure of the dirt collecting port to collect the dirt.

[0112] Of course, the cleaning device 1000 may further include a dirt collecting box (not shown), which is connected to the dirt collecting channel 200. Pollutants are collected into the dirt collecting box through the dirt collecting channel 200, and the user can periodically pull out the dirt collecting box for cleaning.

[0113] Specifically, the cleaning device 1000 can be a sweeping robot, a mopping machine, a floor scrubber, or the like.
