Description

Technical Field

[0001] The present disclosure relates to the technical field of cleaning equipment manufacturing, and in particular to a cleaning equipment brush head, a cleaning equipment and a cleaning system. Background Art

[0002] During the cleaning process, the brush head of a cleaning device often encounters impurities such as hair and cotton threads waiting to be cleaned. In the field of cleaning device manufacturing technology, the anti-entanglement ability of the existing brush head of a cleaning device is poor, which causes the impurities such as hair and cotton threads to be easily entangled on the roller brush, thus seriously affecting the normal operation of the brush head of the cleaning device.

[0087] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be comprehensive and complete and will fully convey the concepts of the example embodiments to those skilled in the art. The same reference numerals in the figures represent the same or similar structures, and thus their detailed description will be omitted.

[0088] Although relative terms such as "upper" and "lower" are used in this specification to describe the relative relationship of one component of the illustration to another component, these terms are used in this specification only for convenience, such as according to the orientation of the examples described in the drawings. It is understood that if the device of the illustration is turned upside down, the component described as "upper" will become the component "lower". When a structure is "on" other structures, it may mean that the structure is formed integrally on the other structure, or that the structure is "directly" disposed on the other structure, or that the structure is "indirectly" disposed on the other structure through another structure.

[0089] The terms "a", "an", "the", and "said" are used to indicate the presence of one or more elements / components / etc.; the terms "including" and "having" are used to express an open-ended inclusion and mean that additional elements / components / etc. may exist in addition to the listed elements / components / etc.; the terms "first" and "second", etc. are used merely as labels and are not intended to limit the quantity of their objects.

[0090] like Figures 1 to 10 As shown, the present disclosure first provides a cleaning device brush head, which can be applied to cleaning devices such as vacuum cleaners, floor scrubbers, sweeping robots, etc. The cleaning device brush head can include: a main body 1, a roller brush 2, and comb teeth 3.

[0091] The main body 1 can be used to provide a mounting position and support for other components of the cleaning device brush head. The main body 1 may include an air suction port 11 .

[0092] The roller brush 2 can be arranged on the main body 1 and can rotate relative to the main body 1 to clean the surface to be cleaned by the roller brush 2. The outer peripheral surface of the roller brush 2 can be arranged opposite to the air suction port 11 so that the dirt cleaned by the roller brush 2 can be directly sucked into the air duct through the air flow of the air suction port 11.

[0093] The comb teeth 3 can be mounted on the main body 1 and can be used to remove dirt from the roller brush 2. The comb teeth 3 can be located on the side of the roller brush 2 close to the air suction port 11. The comb teeth 3 can include a plurality of teeth 31 arranged along the first direction X, the teeth 31 can extend in the direction close to the roller brush 2, and at least part of the teeth 31 can have a first acute angle α between the extension direction Z and the first direction X. For example, the angle of the first acute angle α can be 5°, 10°, 15°, 20°, 25°, 30°, 35°, 40°, 45°, 50°, 55°, 60°, 65°, 70°, 75°, 80°, 85°, etc. The above-mentioned first direction X can be the axial direction of the roller brush 2. That is, it can be understood that the teeth 31 are inclined relative to the roller brush 2.

[0094] Therefore, when the roller brush 2 is rotating, the inclined teeth 31 can be used to hook and break up the hair, cotton thread and other impurities waiting to be cleaned that are entangled on the roller brush 2, and the airflow in the suction port 11 can be used to directly suck the broken hair, cotton thread and other impurities waiting to be cleaned into the air duct.

[0095] Therefore, the cleaning device brush head provided by the present disclosure has good anti-entanglement capability, which can effectively avoid the problem that hair, cotton thread and other impurities to be cleaned are constantly entangled on the roller brush 2, thus affecting the normal operation of the cleaning device brush head. In addition, the cleaning device brush head can suck hair, cotton thread and other impurities to be cleaned into the air duct in time, thereby improving the cleaning capability and cleaning effect of the cleaning device brush head.

[0096] In one embodiment, the first acute angle α may be greater than or equal to 25° and less than or equal to 85°. For example, in this embodiment, the first acute angle may be 25°, 30°, 35°, 40°, 45°, 50°, 55°, 60°, 65°, 70°, 75°, 80°, 85°, etc. This arrangement can avoid the problem of the tooth portion 31 being too inclined due to the first acute angle α being too small, and can also avoid the problem that the tooth portion 31 cannot hook the hair, cotton thread, and impurities waiting to be cleaned.

[0097] At the same time, such a configuration can avoid the problem that the angle of the first acute angle α is too large, which makes the inclination of the tooth portion 31 small, so that the tooth portion 31 can better hook the hair and cotton thread waiting to be cleaned impurities, and prevent the hair and cotton thread waiting to be cleaned impurities from slipping off the tooth portion 31. In addition, such a configuration can make the shear stress of the tooth portion 31 on the hair and cotton thread waiting to be cleaned impurities greater, so that it is more conducive to the tooth portion 31 to break up the hair and cotton thread waiting to be cleaned impurities, and it can further prevent the hair and cotton thread waiting to be cleaned impurities from being constantly entangled on the roller brush 2, so as to further improve the anti-entanglement ability of the brush head of the cleaning device, and further improve the cleaning ability and cleaning effect of the brush head of the cleaning device.

[0098] In one embodiment of the present disclosure, Figure 2 and Figure 3 As shown, in the first direction X, at least part of the teeth 31 extends toward the center of the roller brush. With this arrangement, hair and cotton threads waiting to be cleaned impurities can be hooked and scattered by the teeth 31 when they are in the middle of the roller brush 2, thereby effectively preventing the hair and cotton threads waiting to be cleaned impurities from moving from the middle to the two ends of the roller brush 2, and also preventing the hair and cotton threads waiting to be cleaned impurities from being rolled into the inner side of the brush head at the two ends of the roller brush 2 and affecting the normal operation of the roller brush 2.

[0099] In one embodiment, in the first direction X, all teeth 31 can extend toward the center of the roller brush. This arrangement can further ensure that hair and cotton thread impurities waiting to be cleaned are hooked and scattered by the teeth 31 when they are in the middle of the roller brush 2, thereby ensuring that hair and cotton thread impurities waiting to be cleaned will not move from the middle to the two ends of the roller brush 2, and also ensuring that hair and cotton thread impurities waiting to be cleaned will not be rolled into the inner side of the brush head at the two ends of the roller brush 2 to affect the normal operation of the roller brush 2.

[0100] In one embodiment of the present disclosure, the comb teeth 3 may include: a first tooth group 32 and a second tooth group 33. The first tooth group 32 and the second tooth group 33 may each include at least one tooth portion 31. In the first direction X, the first tooth group 32 and the second tooth group 33 may be located on both sides of the center of the roller brush, respectively, so that the comb teeth 3 may be used to clean the hair, cotton thread and impurities waiting to be cleaned that are entangled on both sides of the center of the roller brush, thereby further improving the anti-entanglement ability of the brush head of the cleaning device.

[0101] Furthermore, the tooth portions 31 in the first tooth group 32 and the second tooth group 33 can both extend toward the center of the roller brush, thereby effectively preventing the hair and cotton threads entangled on both sides of the center of the roller brush from moving toward the two ends of the roller brush 2, thereby ensuring the normal operation of the roller brush 2 and improving the anti-entanglement ability of the brush head of the cleaning equipment.

[0102] In one embodiment, the number of teeth 31 in the first tooth group 32 can be the same as the number of teeth 31 in the second tooth group 33. This arrangement ensures that the comb teeth 3 have the same cleaning ability for the hair and cotton threads waiting to be cleaned impurities entangled on both sides of the center of the roller brush, avoiding the problem that the number of teeth 31 on one side of the center of the roller brush is small, resulting in poor cleaning ability for the hair and cotton threads waiting to be cleaned impurities on this side, and thus ensuring that the brush head of the cleaning device has a high anti-entanglement ability.

[0103] In one embodiment, the comb teeth 3 may further include a third tooth group 34, which may be located between the first tooth group 32 and the second tooth group 33. The third tooth group 34 may include at least one tooth portion 31, and the extension direction Z of the tooth portion 31 in the third tooth group 34 may be perpendicular to the first direction X.

[0104] Since the first tooth group 32 and the second tooth group 33 are located on both sides of the center of the roller brush respectively, and the third tooth group 34 is located between the first tooth group 32 and the second tooth group 33, the third tooth group 34 is located in the first direction X at the center of the roller brush.

[0105] Therefore, the present invention can use the third tooth group 34 to directly hook out and break up the hair and cotton impurities waiting to be cleaned that are entangled at the center of the roller brush using the tooth portion 31 in the third tooth group 34. Thus, the present invention can use the third tooth portion 31 to cooperate with the first tooth group 32 and the second tooth group 33 to clean all the hair and cotton impurities waiting to be cleaned that are entangled on the entire roller brush 2, thereby reducing the cleaning dead angle of the comb teeth 3 on the roller brush 2, and further improving the anti-entanglement ability of the brush head of the cleaning device.

[0106] In another embodiment of the present disclosure, the comb teeth 3 may include: a fourth tooth group 35 and a fifth tooth group 36. The fourth tooth group 35 and the fifth tooth group 36 may each include at least one tooth portion 31. In the first direction X, the fourth tooth group 35 and the fifth tooth group 36 may be located on both sides of the center line 14 of the air suction port, respectively, and the teeth 31 in the fourth tooth group 35 and the fifth tooth group 36 may both extend in a direction close to the center line 14 of the air suction port, so that the air suction port 11 can easily suck the hair, cotton thread and impurities waiting to be cleaned by the tooth portion 31 into the air duct, thereby further improving the anti-entanglement ability of the brush head of the cleaning device.

[0107] In one embodiment, the number of teeth 31 in the fourth tooth group 35 may be the same as the number of teeth 31 in the fifth tooth group 36. This arrangement ensures that the comb teeth 3 have the same cleaning ability on both sides of the center line 14 of the air suction port.

[0108] In one embodiment, the comb teeth 3 may further include a sixth tooth group 37, which may be located between the fourth tooth group 35 and the fifth tooth group 36. The sixth tooth group 37 may include at least one tooth portion 31, and the extension direction Z of the tooth portion 31 in the sixth tooth group 37 may be perpendicular to the first direction X.

[0109] Since the fourth tooth group 35 and the fifth tooth group 36 are respectively located on both sides of the center line 14 of the air suction port, and the sixth tooth group is located between the fourth tooth group 35 and the fifth tooth group 36, the sixth tooth group 37 is located at the position of the center line 14 of the air suction port in the first direction X.

[0110] Therefore, the air suction port 11 can directly hook out the teeth 31 in the third teeth group 34 and break up the hair, cotton thread and other impurities to be cleaned and sucked into the air duct. Thus, such a configuration can further facilitate the air suction port 11 to suck the hair, cotton thread and other impurities broken up by the teeth 31 into the air duct, thereby further improving the anti-entanglement ability of the brush head of the cleaning device.

[0111] In one embodiment of the present disclosure, the extension line of the center line 14 of the air suction port can pass through the center of the roller brush. In this way, the center position of the air suction port 11 in the first direction X can be the same as the center position of the roller brush 2 in the first direction X, so that the hair and cotton threads that are entangled on the entire roller brush 2 can be cleaned by the comb teeth 3, so as to reduce the cleaning dead angle of the roller brush 2 by the comb teeth 3, and the air suction port 11 can be convenient for sucking the hair and cotton threads that are scattered by the teeth 31 into the air duct, thereby further improving the anti-entanglement ability of the brush head of the cleaning device.

[0112] In this embodiment, when the extension line of the center line 14 of the suction port passes through the center of the roller brush, the first tooth group 32 can be the same tooth group as the fourth tooth group 35, the second tooth group 33 can be the same tooth group as the fifth tooth group 36, and the third tooth group 34 can be the same tooth group as the sixth tooth group 37.

[0113] In one embodiment of the present disclosure, Figure 4 As shown, in the first direction X, a plurality of teeth 31 can be arranged at intervals, and the spacing L1 between any two adjacent teeth 31 can be the same. In this way, the plurality of teeth 31 can be arranged evenly in the first direction X, thereby improving its ability to clean hair, cotton thread and other impurities. In addition, such an arrangement can improve the structural strength of the comb teeth 3, avoiding the problem of poor structural strength of the comb teeth 3 in some positions of the comb teeth 3 due to sparse distribution of the teeth 31, thereby improving the service life of the comb teeth 3 and the service life of the brush head of the cleaning device.

[0114] The spacing L1 between any two adjacent teeth 31 can be greater than or equal to 2.5mm and less than or equal to 15mm, for example: 2.5mm, 3mm, 3.5mm, 4mm, 4.5mm, 5mm, 5.5mm, 6mm, 6.5mm, 7mm, 7.5mm, 8mm, 8.5mm, 9mm, 9.5mm, 10mm, 10.5mm, 11mm, 11.5mm, 12mm, 12.5mm, 13mm, 13.5mm, 14mm, 14.5mm, 15mm, etc. In this way, the problem of being easily entangled by hair and cotton thread waiting to be cleaned impurities due to the spacing L1 between two adjacent teeth 31 being too small can be avoided, and the problem of reducing the efficiency of breaking up hair and cotton thread waiting to be cleaned impurities due to the spacing L1 between two adjacent teeth 31 being too large can also be avoided.

[0115] In one embodiment, Figures 1 to 4As shown, the end of the tooth portion 31 close to the roller brush 2 can contact the outer peripheral surface of the roller brush 2. It should be noted that the contact mentioned here refers to the end of the tooth portion 31 close to the roller brush 2 just fitting with the outer peripheral surface of the roller brush 2, at which time there is no interference and no interaction between the tooth portion 31 and the roller brush 2. With such a configuration, the tooth portion 31 can contact the hair, cotton thread and impurities waiting to be cleaned adsorbed on the outer peripheral surface of the roller brush 2, so that the hair, cotton thread and impurities waiting to be cleaned adsorbed on the outer peripheral surface of the roller brush 2 can be hooked and scattered, thereby improving the cleaning effect of the tooth portion 31 and improving the anti-entanglement ability of the brush head of the cleaning device. At the same time, since there is no interference and no interaction between the tooth portion 31 and the roller brush 2, there will be no large friction between the tooth portion 31 and the roller brush 2, and no large noise will be generated, so that the brush head of the cleaning device has a better mute effect.

[0116] In another embodiment, Figures 1 to 6 As shown, the end of the tooth portion 31 close to the roller brush 2 can interfere with the roller brush 2. That is, it can be understood that the end of the tooth portion 31 close to the roller brush 2 can penetrate deep into the roller brush 2. This arrangement allows the tooth portion 31 to contact the hair, cotton thread and impurities waiting to be cleaned located in the roller brush 2, thereby being able to hook and break up the hair, cotton thread and impurities waiting to be cleaned located in the roller brush 2 and on the outer peripheral surface of the roller brush 2. At the same time, this arrangement can also increase the success rate of the tooth portion 31 hooking the hair, cotton thread and impurities waiting to be cleaned, thereby being able to further improve its cleaning effect. It can be seen from this that compared with the previous embodiment, the cleaning device brush head provided in this embodiment has better anti-entanglement ability.

[0117] In this embodiment, in the second direction Y, the interference amount S between the tooth portion 31 and the roller brush 2 may be less than or equal to 1 mm, for example, 0.1 mm, 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1 mm, etc. The second direction Y may be the direction in which the tooth portion 31 points to the roller brush 2. In this way, it is possible to avoid the roller brush 2 from damaging the tooth portion 31 during rotation due to excessive interference amount S between the tooth portion 31 and the roller brush 2, and it is also possible to avoid the tooth portion 31 blocking the rotation of the roller brush 2 and affecting the normal operation of the roller brush 2.

[0118] However, it is not limited to this, there may also be a gap between the end of the tooth portion 31 close to the roller brush 2 and the outer peripheral surface of the roller brush 2. Such a setting can further reduce the noise of the brush head of the cleaning device during operation, and can also clean some suspended hair, cotton threads and impurities waiting to be cleaned.

[0119] In one embodiment of the present disclosure, Figure 4 and Figure 5As shown, the tooth portion 31 may include a top wall 311 away from the main body 1, and two side walls 312 located on both sides of the top wall 311. The top wall 311 mentioned here may be the end of the tooth portion 31 close to the roller brush 2 mentioned above.

[0120] In one embodiment, Figure 4 As shown, the two side walls 312 may be parallel to reduce the difficulty of manufacturing the tooth portion 31 .

[0121] In another embodiment, Figure 5 As shown, the spacing between the two side walls 312 can be gradually reduced in the direction away from the main body 1, so as to increase the sharpness of the teeth 31, making it easier for the teeth 31 to break up the hair, cotton thread and impurities waiting to be cleaned that are entangled on the roller brush 2.

[0122] The extension length L2 of the tooth portion 31 can be greater than or equal to 1.5 mm and less than or equal to 3.5 mm, for example, 1.5 mm, 2 mm, 2.5 mm, 3 mm, 3.5 mm, etc. This arrangement can avoid the problem of poor ability to break up hair and cotton threads waiting for cleaning impurities due to the short extension length L2 of the tooth portion 31, and can also avoid the problem of poor structural strength due to the extension length L2 of the tooth portion 31, thereby improving the service life of the comb teeth 3.

[0123] The material of the comb teeth 3 can be hard rubber, so that the tooth portion 31 has a good structural strength to facilitate the removal of hair, cotton thread and other impurities, and at the same time, the tooth portion 31 can have a certain flexibility to avoid damaging the roller brush 2 when the tooth portion 31 contacts the roller brush 2. However, it is not limited to this, and the material of the comb teeth 3 can also be metal material, soft rubber, etc., which can be set according to actual needs, which is within the protection scope of the present disclosure.

[0124] In one embodiment of the present disclosure, Figure 1 , Figure 2 and Figure 6 As shown, the main body 1 may include: a first shell 12 and a second shell 13. The first shell 12 and the second shell 13 may enclose a receiving cavity, the roller brush 2 and the comb teeth 3 may both be located in the receiving cavity, and the roller brush 2 may be arranged on the first shell 12 or the second shell 13. In this way, the first shell 12 and the second shell 13 may be used to protect the roller brush 2 and the comb teeth 3, and prevent the roller brush 2 and the comb teeth 3 from directly colliding with obstacles in the external environment, thereby reducing the probability of damage to the roller brush 2 and the comb teeth 3, and further increasing the service life of the brush head of the cleaning device.

[0125] In one embodiment, the comb teeth 3 can be installed on the first housing 12. That is, it can be understood that the comb teeth 3 and the first housing 12 can be split structures, and the comb teeth 3 can be installed on the first housing 12 as a separate structural member through a connecting structure. Such a setting can reduce the difficulty of manufacturing the comb teeth 3 and the first housing 12.

[0126] In one embodiment, the comb teeth 3 and the first housing 12 can be an integrated structure. That is, it can be understood that the comb teeth 3 and the first housing 12 can be manufactured simultaneously through an integrated process, and there is no need to connect the two together through a connecting structure. In this way, the connection points between the comb teeth 3 and the first housing 12 can be reduced to improve the connection strength between the comb teeth 3 and the first housing 12.

[0127] In one embodiment, the comb teeth 3 can be installed on the second housing 13. That is, it can be understood that the comb teeth 3 and the second housing 13 can be split structures, and the comb teeth 3 can be installed on the second housing 13 as a separate structural member through a connecting structure. Such an arrangement can reduce the difficulty of manufacturing the comb teeth 3 and the second housing 13.

[0128] In one embodiment, the comb teeth 3 and the second housing 13 can be an integrated structure. That is, it can be understood that the comb teeth 3 and the second housing 13 can be manufactured simultaneously through an integrated process, and there is no need to connect the two together through a connecting structure. In this way, the connection points between the comb teeth 3 and the second housing 13 can be reduced to improve the connection strength between the comb teeth 3 and the second housing 13.

[0129] In one embodiment of the present disclosure, Figure 1 , Figures 6 to 10 As shown, the roller brush 2 may include: a roller 21, a cleaning brush 22 and a support bar 23. The cleaning brush 22 may be arranged at intervals along the outer circumference of the roller 21, and the cleaning brush 22 may have a receiving groove 221. The support bar 23 may be arranged in the receiving groove 221.

[0130] The support bar 23 may have a first structure portion 231, and a second structure portion 232 and a third structure portion 233 respectively located on both sides of the first structure portion 231; when the first structure portion 231 rotates to the side of the drum 21 away from the air inlet 11, the distance between the first structure portion 231 and the air inlet 11 may be greater than the distance between the second structure portion 232 and the air inlet 11, and the distance between the first structure portion 231 and the air inlet 11 may be greater than the distance between the third structure portion 233 and the air inlet 11. In this way, the support bar 23 can be used to support the cleaning brush 22, so that hair, cotton thread and other cleaning impurities cannot be squeezed into the cleaning brush 22 in a short time, thereby improving the anti-entanglement ability of the brush head of the cleaning device.

[0131] Multiple receiving grooves 221 and support bars 23 can be provided. Multiple receiving grooves 221 can be arranged at intervals, and one support bar 23 can be provided in one receiving groove 221. In this way, multiple support bars can be used to support the cleaning brush 22, which is more conducive to preventing hair, cotton thread and other cleaning impurities from being stuck in the cleaning brush 22 in a short time.

[0132] The receiving groove 221 can expose part of the outer circumference of the drum 21, and the support bar 23 can be arranged on the part of the outer circumference of the drum 21 exposed by the receiving groove 221. Such arrangement can improve the stability of the support bar 23, so as to further improve the support ability of the support bar 23 to the cleaning brush 22.

[0133] In one embodiment, the receiving groove 221 can penetrate the cleaning brush 22 along the first direction X, and the support bar 23 can penetrate the receiving groove 221 along the first direction. With this arrangement, the support bar 23 can be used to separate the cleaning brush 22 to further prevent hair, cotton thread and other cleaning impurities from being strangled into the cleaning brush 22 in a short time, thereby further improving the anti-entanglement ability of the brush head of the cleaning device.

[0134] In one embodiment, when the first structure portion 231 rotates to the side of the drum 21 away from the air suction port 11 , the projection of the support bar 23 in the second direction Y may be V-shaped, but is not limited thereto.

[0135] The angle β of the V-shaped support bar 23 can be greater than or equal to 60° and less than or equal to 160°, for example: 60°, 70°, 80°, 90°, 100°, 110°, 120°, 130°, 140°, 150°, 160°, etc. Such a configuration can ensure that the support bar 23 has a good supporting capacity.

[0136] Further, the angle β of the V-shaped support bar 23 can be greater than or equal to 120° and less than or equal to 150°, for example, 120°, 125°, 130°, 135°, 140°, 145°, 150°, etc. This arrangement can further improve the support capacity of the support bar 23.

[0137] In one embodiment, Figures 6 to 10As shown, the second structure part 232 and the third structure part 233 of the support bar 23 can be in a spiral shape, which can reduce the probability of impurities such as hair and cotton thread being entangled on the support bar 23, so as to further improve the anti-entanglement ability of the brush head of the cleaning device. The support bar 23 can be a sheet structure, and the part of the second structure part 232 away from the third structure part 233 and the part of the third structure part 233 away from the second structure part 232 can be in a horizontal plane shape, and the rest of the second structure part 232 and the rest of the third structure part 233 are gradually twisted to a vertical state through a spiral shape, so that the support bar 23 at the first structure part 231 can be in a vertical plane shape, and the first structure part can have the above-mentioned angle β, so that the second structure part 232 and the third structure part 233 are also set at the above-mentioned angle β.

[0138] Furthermore, before the support bar 23 is assembled in the receiving groove 221, it can be straight. When the support bar 23 needs to be assembled in the receiving groove 221, the support bar 23 can be twisted so that the second structure part 232 and the third structure part 233 are in a spiral shape, and the first structure part 231 has the above-mentioned angle β. However, it is not limited to this. Before the support bar 23 is assembled in the receiving groove 221, it may not be straight, and it may be directly in the above-mentioned spiral shape and have the above-mentioned angle β.

[0139] The support bar 23 may have an outer side 234 away from the roller brush 2 and an inner side 235 close to the roller brush 2 .

[0140] In one embodiment, along the first direction X, the distances from the outer side 234 of the first structure portion 231 to the center line of the roller brush 2 extending along the first direction X may be equal, so as to reduce the difficulty of manufacturing the support bar 23 and facilitate the manufacturing of the support bar 23 .

[0141] In another embodiment, along the first direction X, from one side of the first structure part 231 to the middle of the first structure part 231, the distance from the outer side 234 of the first structure part 231 to the center line of the roller brush 2 extending along the first direction X can be gradually reduced. In this way, when impurities such as hair and cotton threads are entangled on the roller brush 2, the support bar 23 can guide the impurities such as hair and cotton threads to the air suction port 11 as the roller brush 2 rotates, so that the air suction port 11 can suck in impurities such as hair and cotton threads, thereby improving the cleaning effect of the brush head of the cleaning device.

[0142] Along the first direction X, from both sides of the first structure part 231 to the middle of the first structure part 231, the distance from the outer side 234 of the first structure part 231 to the center line of the roller brush 2 extending along the first direction X can be gradually reduced. With such a configuration, compared with the previous embodiment, the guiding ability of the support bar 23 can be further improved, the guiding effect on impurities such as hair and cotton threads can be ensured, and the cleaning effect of the brush head of the cleaning device can be further improved.

[0143] In one embodiment, there may be a gap between the end of the tooth portion 31 close to the roller brush 2 and the support bar 23, so that friction between the tooth portion 31 and the support bar 23 can be avoided, and noise caused by friction between the tooth portion 31 and the support bar 23 can be avoided, thereby improving the mute effect of the brush head of the cleaning device. When there is no friction between the tooth portion 31 and the support bar 23, wear of the support bar 23 can also be avoided, thereby increasing the service life of the roller brush 2.

[0144] In another embodiment, the end of the tooth portion 31 close to the roller brush 2 can contact the surface of the support bar 23. It should be noted that the contact mentioned here means that the end of the tooth portion 31 close to the roller brush 2 just fits the surface of the support bar 23, and there is no interference and no interaction between the tooth portion 31 and the support bar 23. In this way, the tooth portion 31 can contact the hair, cotton thread and impurities waiting to be cleaned adsorbed on the support bar 23, so that the hair, cotton thread and impurities waiting to be cleaned adsorbed on the support bar 23 can be hooked and scattered, thereby improving the cleaning effect of the tooth portion 31 and improving the anti-entanglement ability of the brush head of the cleaning device. At the same time, since there is no interference and no interaction between the tooth portion 31 and the support bar 23, there will be no large friction between the tooth portion 31 and the roller brush 2, and no large noise will be generated, so that the brush head of the cleaning device can also have a good mute effect.

[0145] In another embodiment, the end of the tooth portion 31 close to the roller brush 2 may interfere with the support bar 23. That is, it is understood that there may be an interference amount and interaction force between the end of the tooth portion 31 close to the roller brush 2 and the support bar 23. Such a configuration can improve the success rate of the tooth portion 31 hooking the hair, cotton thread and impurities waiting to be cleaned on the surface of the support bar 23, thereby further improving the cleaning effect of the tooth portion 31, so that the brush head of the cleaning device has better anti-entanglement ability.

[0146] In one embodiment of the present disclosure, the hardness of the support bar 23 may be greater than the hardness of the cleaning brush 22 to ensure the support effect of the support bar 23. The material of the support bar 23 may be soft rubber, but is not limited thereto. The material of the support bar 23 may be hard rubber, etc., and may be selected and set according to actual needs, which is within the scope of protection of the present disclosure.

[0147] Another aspect of the present disclosure provides a cleaning device. The cleaning device may include: a cleaning device body and a cleaning device brush head. The cleaning device may be a vacuum cleaner, a floor scrubber, a sweeping robot, etc. The cleaning device brush head may be the cleaning device brush head described above, and the cleaning device body may be connected to the cleaning device brush head.

[0148] It should be noted that the present disclosure has already described in detail the specific structure and beneficial effects of the brush head of the cleaning device in the previous embodiment, so in this embodiment, the specific structure and beneficial effects of the brush head of the cleaning device will not be repeated.

The comb teeth 3 may include a plurality of teeth 31 arranged along a first direction X, and at least part of the teeth 31 may have a first acute angle α between the extension direction Z and the first direction X. That is, it can be understood that the teeth 31 are inclined relative to the roller brush 2.

[0150] Therefore, when the roller brush 2 is rotating, the inclined teeth 31 can be used to hook and break up the hair, cotton thread and other impurities waiting to be cleaned that are entangled on the roller brush 2, and the airflow in the suction port 11 can be used to directly suck the broken hair, cotton thread and other impurities waiting to be cleaned into the air duct.

[0151] Therefore, the cleaning device brush head provided by the present disclosure has good anti-entanglement capability, which can effectively avoid the problem that hair, cotton threads and other cleaning impurities are constantly entangled on the roller brush 2 and affect the normal operation of the cleaning device brush head. In addition, the cleaning device brush head can suck hair, cotton threads and other cleaning impurities into the air duct in time, thereby improving the cleaning ability and cleaning effect of the cleaning device brush head, and further improving the cleaning ability and cleaning effect of the cleaning device.

[0152] In another aspect, the present disclosure provides a cleaning system. The cleaning system may include: a base station and a cleaning device. The cleaning device may be the cleaning device described above, and the cleaning device may be connected to the base station.

The comb teeth 3 may include a plurality of teeth 31 arranged along a first direction X, and at least part of the teeth 31 may have a first acute angle α between the extension direction Z and the first direction X. That is, it can be understood that the teeth 31 are inclined relative to the roller brush 2.

[0155] Therefore, when the roller brush 2 is rotating, the inclined teeth 31 can be used to hook and break up the hair, cotton thread and other impurities waiting to be cleaned that are entangled on the roller brush 2, and the airflow in the suction port 11 can be used to directly suck the broken hair, cotton thread and other impurities waiting to be cleaned into the air duct.

[0156] Therefore, the cleaning device brush head provided by the present disclosure has good anti-entanglement capability, which can effectively avoid the problem that hair, cotton threads and other cleaning impurities are constantly entangled on the roller brush 2 and affect the normal operation of the cleaning device brush head. In addition, the cleaning device brush head can suck hair, cotton threads and other cleaning impurities into the air duct in time, thereby improving the cleaning ability and cleaning effect of the cleaning device brush head, and further improving the cleaning ability and cleaning effect of the cleaning system.
