Description

Technical Field

[0001] This disclosure relates to the field of cleaning equipment manufacturing technology, and in particular to a cleaning equipment brush head, cleaning equipment, and cleaning system. Background Technology

[0002] During the cleaning process, cleaning equipment brush heads often encounter debris such as hair and lint. In the field of cleaning equipment manufacturing technology, existing cleaning equipment brush heads have poor anti-tangling capabilities, making it easy for debris such as hair and lint to get tangled on the roller brush, thus seriously affecting the normal operation of the cleaning equipment brush head.

[0003] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0086] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed description will be omitted.

[0087] Although relative terms such as "up" and "down" are used in this specification to describe the relative relationship of one component of an icon to another, these terms are used only for convenience, such as according to the orientation of the examples shown in the accompanying drawings. It is understood that if the device of the icon is flipped upside down, the component described as "up" will become the component described as "down." When a structure is "up" of another structure, it may mean that the structure is integrally formed on the other structure, or that the structure is "directly" mounted on the other structure, or that the structure is "indirectly" mounted on the other structure through another structure.

[0088] The terms “a,” “one,” “the,” and “the” are used to indicate the existence of one or more elements / components / etc.; the terms “including” and “having” are used to indicate an open-ended inclusion meaning and that there may be other elements / components / etc. in addition to the listed elements / components / etc.; the terms “first” and “second” are used only as markers and are not a limitation on the number of objects.

[0089] like Figures 1 to 10 As shown, this disclosure first provides a cleaning device brush head that can be applied to cleaning devices such as vacuum cleaners, floor scrubbers, and robotic vacuum cleaners. The cleaning device brush head may include: a main body 1, a roller brush 2, and comb teeth 3.

[0090] The main body 1 can be used to provide mounting positions and support for other components of the cleaning equipment brush head. The main body 1 may include an air intake 11.

[0091] The roller brush 2 can be disposed on the main body 1 and can rotate relative to the main body 1 to clean the surface to be cleaned. The outer peripheral surface of the roller brush 2 can be disposed opposite to the air intake 11 so that the dirt cleaned by the roller brush 2 can be directly sucked into the air duct through the airflow of the air intake 11.

[0092] The comb teeth 3 can be installed 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 near the air intake 11. The comb teeth 3 can include a plurality of teeth 31 arranged along a first direction X. The teeth 31 can extend towards the roller brush 2, and at least some of the teeth 31 can have a first acute angle α between their 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 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.

[0093] Therefore, when the roller brush 2 is rotating, the inclined teeth 31 can hook and disperse the hair, cotton thread and other cleaning impurities wrapped around the roller brush 2, and the airflow in the suction port 11 can directly suck the dispersed hair, cotton thread and other cleaning impurities into the air duct.

[0094] Therefore, the cleaning equipment brush head provided in this disclosure has good anti-tangling ability, which can effectively avoid the problem of hair, cotton thread, and other cleaning impurities constantly tangling on the roller brush 2, thus affecting the normal operation of the cleaning equipment brush head. Furthermore, this cleaning equipment brush head can promptly draw hair, cotton thread, and other cleaning impurities into the air duct, thereby improving the cleaning ability and cleaning effect of the cleaning equipment brush head.

[0095] In one embodiment, the angle of the first acute angle α can be greater than or equal to 25° and less than or equal to 85°. For example, in this embodiment, the angle of the first acute angle can be 25°, 30°, 35°, 40°, 45°, 50°, 55°, 60°, 65°, 70°, 75°, 80°, 85°, etc. This setting can avoid the problem of the tooth 31 having a large inclination angle due to the first acute angle α being too small, and thus avoid the problem of the tooth 31 being unable to hook hair, cotton thread, or other cleaning impurities.

[0096] Meanwhile, this design avoids the problem of an excessively large first acute angle α, resulting in a small inclination of the teeth 31. This allows the teeth 31 to better hook onto hair, cotton threads, and other cleaning impurities, preventing them from slipping off. Furthermore, this design allows for greater shear stress exerted by the teeth 31 on the hair, cotton threads, and other cleaning impurities, making it easier for the teeth 31 to disperse them. This further prevents hair, cotton threads, and other cleaning impurities from continuously tangling on the roller brush 2, thereby further improving the anti-tangling ability of the cleaning device brush head and enhancing its cleaning capacity and effect.

[0097] In one embodiment of this disclosure, such as Figure 2 and Figure 3 As shown, in the first direction X, at least a portion of the teeth 31 extend towards the center of the roller brush. This arrangement allows hair, lint, and other cleaning impurities to be hooked and dispersed by the teeth 31 when they are in the middle of the roller brush 2. This effectively prevents hair, lint, and other cleaning impurities from moving from the middle of the roller brush 2 towards both ends, and also prevents hair, lint, and other cleaning impurities from getting caught in the inner side of the brush heads at both ends of the roller brush 2, thus affecting the normal operation of the roller brush 2.

[0098] In one embodiment, in the first direction X, all teeth 31 can extend towards the center of the roller brush. This arrangement further ensures that hair, lint, and other cleaning impurities are hooked and dispersed by the teeth 31 when they are in the middle of the roller brush 2, thereby preventing them from moving from the middle of the roller brush 2 to both ends. This also ensures that hair, lint, and other cleaning impurities will not be rolled into the inside of the brush heads at both ends of the roller brush 2 and affect the normal operation of the roller brush 2.

[0099] In one embodiment of this disclosure, the comb teeth 3 may include a first tooth group 32 and a second tooth group 33. Both the first tooth group 32 and the second tooth group 33 may include at least one tooth 31. In the first direction X, the first tooth group 32 and the second tooth group 33 may be located on either side of the center of the roller brush, thereby enabling the comb teeth 3 to clean hair, lint, and other cleaning impurities entangled on either side of the center of the roller brush, thus further improving the anti-tangling capability of the cleaning device brush head.

[0100] Furthermore, the teeth 31 in the first tooth group 32 and the second tooth group 33 can both extend towards the center of the roller brush, which can effectively prevent hair, cotton thread and other cleaning impurities wrapped around the center of the roller brush from moving to both ends of the roller brush 2, thereby ensuring the normal operation of the roller brush 2 and improving the anti-tangling ability of the cleaning equipment brush head.

[0101] 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 hair, cotton threads, and other cleaning impurities wrapped around the center of the roller brush on both sides, avoiding the problem that the cleaning ability for hair, cotton threads, and other cleaning impurities on the side with fewer teeth 31 located on the center side of the roller brush is poor. This also ensures that the brush head of the cleaning device has a high anti-tangling ability.

[0102] 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 extending direction Z of the tooth portion 31 in the third tooth group 34 may be perpendicular to the first direction X.

[0103] Since the first tooth group 32 and the second tooth group 33 are located on both sides of the center of the roller brush, 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 at the center of the roller brush in the first direction X.

[0104] Therefore, by setting a third tooth group 34, the teeth 31 in the third tooth group 34 can directly hook out and disperse hair, cotton thread, and other cleaning impurities wrapped around the center of the roller brush. Thus, the third tooth group 31, in conjunction with the first tooth group 32 and the second tooth group 33, can clean all the hair, cotton thread, and other cleaning impurities wrapped around the entire roller brush 2, thereby reducing the cleaning dead zones of the roller brush 2 by the comb teeth 3 and further improving the anti-tangling ability of the cleaning equipment brush head.

[0105] In another embodiment of this disclosure, the comb teeth 3 may include a fourth tooth group 35 and a fifth tooth group 36. Both the fourth tooth group 35 and the fifth tooth group 36 may include at least one tooth 31. In the first direction X, the fourth tooth group 35 and the fifth tooth group 36 may be located on either side of the centerline 14 of the air intake, and the teeth 31 in both groups may extend towards the centerline 14 of the air intake. This facilitates the air intake 11 drawing the hair, cotton threads, and other cleaning impurities dispersed by the teeth 31 into the air duct, thereby further improving the anti-tangling capability of the cleaning device brush head.

[0106] In one embodiment, the number of teeth 31 in the fourth tooth group 35 can 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 capacity on both sides of the center line 14 of the air intake.

[0107] 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 extending direction Z of the tooth portion 31 in the sixth tooth group 37 may be perpendicular to the first direction X.

[0108] Since the fourth tooth group 35 and the fifth tooth group 36 are located on both sides of the center line 14 of the air intake, 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 intake in the first direction X.

[0109] Therefore, the suction port 11 can directly hook out the teeth 31 in the third tooth group 34 and loosen hair, cotton thread, and other cleaning impurities before drawing them into the air duct. Thus, this arrangement further facilitates the suction port 11 in drawing the loosened hair, cotton thread, and other cleaning impurities into the air duct, thereby further improving the anti-tangling ability of the cleaning equipment brush head.

[0110] In one embodiment of this disclosure, the extension line of the center line 14 of the air intake can pass through the center of the roller brush. This arrangement ensures that the center position of the air intake 11 in the first direction X is the same as the center position of the roller brush 2 in the first direction X. This allows the comb teeth 3 to clean all hair, lint, and other cleaning impurities entangled on the roller brush 2, reducing blind spots in cleaning the roller brush 2. Furthermore, it facilitates the air intake 11 in drawing the hair, lint, and other cleaning impurities dispersed by the teeth 31 into the air duct, thereby further improving the anti-tangling capability of the cleaning device's brush head.

[0111] In this embodiment, when the extension of the center line 14 of the air intake 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.

[0112] In one embodiment of this disclosure, such as Figure 4 As shown, in the first direction X, multiple teeth 31 can be spaced apart, and the distance L1 between any two adjacent teeth 31 can be the same. This arrangement ensures that the multiple teeth 31 are evenly distributed in the first direction X, improving their ability to clean impurities such as hair and lint. Furthermore, this arrangement improves the structural strength of the comb teeth 3, avoiding the problem of poor structural strength in certain parts of the comb teeth 3 due to sparse distribution of teeth 31, thereby extending the service life of the comb teeth 3 and the cleaning device brush head.

[0113] The distance 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. This setting avoids the problem of adjacent teeth 31 being easily entangled by hair, cotton thread, or other cleaning impurities due to an excessively small distance L1, and also avoids the problem of adjacent teeth 31 having an excessively large distance L1, which would reduce its efficiency in dispersing hair, cotton thread, or other cleaning impurities.

[0114] In one embodiment, such as Figures 1 to 4As shown, the end of the tooth 31 near the roller brush 2 can contact the outer peripheral surface of the roller brush 2. It should be noted that this contact refers to the point where the end of the tooth 31 near the roller brush 2 is just touching the outer peripheral surface of the roller brush 2, with no interference and no interaction force between the tooth 31 and the roller brush 2. This design allows the tooth 31 to contact and remove hair, lint, and other cleaning impurities adhering to the outer peripheral surface of the roller brush 2, thereby hooking and dispersing these impurities, improving the cleaning effect of the tooth 31 and enhancing the anti-tangling ability of the cleaning device brush head. Simultaneously, because there is no interference and no interaction force between the tooth 31 and the roller brush 2, there is minimal friction, resulting in low noise and a quiet operation for the cleaning device brush head.

[0115] In another embodiment, such as Figures 1 to 6 As shown, the end of the tooth 31 near the roller brush 2 can interfere with the roller brush 2. That is, it can be understood that the end of the tooth 31 near the roller brush 2 can penetrate deep into the roller brush 2. This arrangement allows the tooth 31 to contact hair, cotton thread, and other cleaning impurities located inside the roller brush 2, thereby hooking and dispersing hair, cotton thread, and other cleaning impurities located inside and on the outer circumference of the roller brush 2. At the same time, this arrangement can also improve the success rate of the tooth 31 in hooking hair, cotton thread, and other cleaning impurities, thereby further improving its cleaning effect. Therefore, it can be seen that, compared with the previous embodiment, the cleaning device brush head provided in this embodiment has better anti-tangling ability.

[0116] In this embodiment, the interference S between the teeth 31 and the roller brush 2 in the second direction Y can 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 can be the direction in which the teeth 31 point towards the roller brush 2. This setting can avoid damage to the teeth 31 during the rotation of the roller brush 2 due to excessive interference S between the teeth 31 and the roller brush 2, and can also prevent the teeth 31 from blocking the rotation of the roller brush 2 and affecting the normal operation of the roller brush 2.

[0117] However, it is not limited to this. There may also be a gap between the end of the tooth 31 near the roller brush 2 and the outer peripheral surface of the roller brush 2. This setting can further reduce the noise of the cleaning device brush head during operation, and at the same time, it can clean some suspended hair, cotton thread and other cleaning impurities.

[0118] In one embodiment of this disclosure, such as Figure 4 and Figure 5As shown, the toothed 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 toothed portion 31 near the roller brush 2 described above.

[0119] In one embodiment, such as Figure 4 As shown, the two sidewalls 312 can be parallel to reduce the manufacturing difficulty of the teeth 31.

[0120] In another embodiment, such as Figure 5 As shown, the distance between the two sidewalls 312 can gradually decrease in the direction away from the main body 1, thereby increasing the sharpness of the teeth 31 and making it easier for the teeth 31 to break up the hair, cotton thread and other cleaning impurities wrapped around the roller brush 2.

[0121] The extension length L2 of the teeth 31 can be greater than or equal to 1.5mm and less than or equal to 3.5mm, for example: 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm, etc. This setting can avoid the problem that the ability to loosen hair and cotton threads and clean impurities is poor due to a short extension length L2 of the teeth 31, and can also avoid the problem that the structural strength is poor due to the extension length L2 of the teeth 31, thereby improving the service life of the comb teeth 3.

[0122] The comb teeth 3 can be made of hard plastic. This design gives the teeth 31 good structural strength to easily loosen hair, lint, and other impurities, while also giving the teeth 31 a certain degree of flexibility to prevent damage to the roller brush 2 when the teeth 31 come into contact with it. However, this is not a limitation. The comb teeth 3 can also be made of metal, soft plastic, etc., depending on actual needs, and all of these are within the scope of protection of this disclosure.

[0123] In one embodiment of this disclosure, such as Figure 1 , Figure 2 and Figure 6 As shown, the main body 1 may include a first housing 12 and a second housing 13. The first housing 12 and the second housing 13 can form a receiving cavity, where the roller brush 2 and the comb teeth 3 can both be located. The roller brush 2 can be mounted on either the first housing 12 or the second housing 13. This arrangement protects the roller brush 2 and the comb teeth 3 from direct collisions with obstacles in the external environment, thereby reducing the probability of damage to the roller brush 2 and the comb teeth 3 and ultimately extending the service life of the cleaning equipment brush head.

[0124] In one embodiment, the comb teeth 3 can be mounted on the first housing 12. That is, it can be understood that the comb teeth 3 and the first housing 12 can be separate structures, and the comb teeth 3 can be mounted on the first housing 12 as a separate structural component via a connecting structure. This arrangement can reduce the manufacturing difficulty of the comb teeth 3 and the first housing 12.

[0125] In one embodiment, the comb teeth 3 and the first housing 12 can be an integral structure. That is, it can be understood that the comb teeth 3 and the first housing 12 can be manufactured simultaneously using an integrated process, without the need for a connecting structure to connect them together. This arrangement reduces the number of connection points between the comb teeth 3 and the first housing 12, thereby improving the connection strength between them.

[0126] In one embodiment, the comb teeth 3 can be mounted on the second housing 13. That is, it can be understood that the comb teeth 3 and the second housing 13 can be separate structures, and the comb teeth 3 can be mounted on the second housing 13 as a separate structural component via a connecting structure. This arrangement can reduce the manufacturing difficulty of the comb teeth 3 and the second housing 13.

[0127] In one embodiment, the comb teeth 3 and the second housing 13 can be an integral structure. That is, it can be understood that the comb teeth 3 and the second housing 13 can be manufactured simultaneously using an integrated process, without the need for a connecting structure to join them together. This arrangement reduces the number of connection points between the comb teeth 3 and the second housing 13, thereby improving the connection strength between the comb teeth 3 and the second housing 13.

[0128] In one embodiment of this disclosure, such as Figure 1 , Figures 6 to 10 As shown, the roller brush 2 may include: a roller 21, a cleaning brush 22, and a support strip 23. The cleaning brush 22 may be spaced apart along the outer circumferential surface of the roller 21, and the cleaning brush 22 may have a receiving groove 221. The support strip 23 may be disposed within the receiving groove 221.

[0129] The support bar 23 may have a first structural portion 231, and a second structural portion 232 and a third structural portion 233 located on both sides of the first structural portion 231. When the first structural portion 231 rotates to the side of the roller 21 away from the air inlet 11, the distance between the first structural portion 231 and the air inlet 11 may be greater than the distance between the second structural portion 232 and the air inlet 11, and the distance between the first structural portion 231 and the air inlet 11 may be greater than the distance between the third structural portion 233 and the air inlet 11. With this configuration, the support bar 23 can support the cleaning brush 22, preventing hair, cotton threads, and other cleaning impurities from getting stuck in the cleaning brush 22 in a short time, thereby improving the anti-tangling ability of the cleaning equipment brush head.

[0130] Multiple receiving slots 221 and support bars 23 can be provided. Multiple receiving slots 221 can be arranged at intervals, and one support bar 23 can be provided in one receiving slot 221. With this arrangement, 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 into the cleaning brush 22 in a short time.

[0131] The receiving groove 221 can expose part of the outer peripheral surface of the roller 21, and the support bar 23 can be disposed on the part of the outer peripheral surface of the roller 21 exposed by the receiving groove 221. This arrangement can improve the stability of the support bar 23, thereby further improving the support ability of the support bar 23 for the cleaning brush 22.

[0132] 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 configuration, the support bar 23 can be used to separate the cleaning brush 22, so as to further prevent hair, cotton thread and other cleaning impurities from getting stuck into the cleaning brush 22 in a short time, thereby further improving the anti-tangling ability of the cleaning device brush head.

[0133] In one embodiment, when the first structural part 231 rotates to the side of the roller 21 away from the air inlet 11, the projection of the support bar 23 in the second direction Y can be V-shaped, but is not limited thereto.

[0134] The included 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. This setting ensures that the support bar 23 has good support capacity.

[0135] Furthermore, the included 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 setting can further improve the support capacity of the support bar 23.

[0136] In one embodiment, such as Figures 6 to 10As shown, the second structural portion 232 and the third structural portion 233 of the support strip 23 can be spiral-shaped, which can reduce the probability of hair, cotton thread and other impurities getting tangled on the support strip 23, thereby further improving the anti-tangling ability of the cleaning device brush head. The support strip 23 can be a sheet-like structure. The portion of the second structural portion 232 away from the third structural portion 233 and the portion of the third structural portion 233 away from the second structural portion 232 can be horizontal. The remaining portions of the second structural portion 232 and the remaining portions of the third structural portion 233 gradually twist towards a vertical state through a spiral shape, so that the support strip 23 at the first structural portion 231 is a vertical plane. The first structural portion can have the aforementioned included angle β, so that the second structural portion 232 and the third structural portion 233 are also set at the aforementioned included angle β.

[0137] Furthermore, the support bar 23 can be straight before it is assembled into the receiving groove 221. When it is necessary to assemble the support bar 23 into the receiving groove 221, the support bar 23 can be twisted so that the second structural part 232 and the third structural part 233 are spiral in shape, and the first structural part 231 has the aforementioned included angle β. However, it is not limited to this; the support bar 23 may not be straight before it is assembled into the receiving groove 221, and it may directly be spiral in shape with the aforementioned included angle β.

[0138] 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.

[0139] In one embodiment, the distance from the outer edge 234 of the first structural part 231 to the center line of the roller brush 2 extending along the first direction X can be equal to reduce the manufacturing difficulty of the support strip 23 and facilitate the manufacturing of the support strip 23.

[0140] In another embodiment, along the first direction X, from one side of the first structural portion 231 to the middle of the first structural portion 231, the distance from the outer edge 234 of the first structural portion 231 to the center line extending along the first direction X of the roller brush 2 can gradually decrease. With this configuration, when hair, lint, or other impurities become entangled on the roller brush 2, the support bar 23 can guide these impurities towards the suction port 11 as the roller brush 2 rotates, facilitating the suction port 11 to draw in the impurities and improve the cleaning effect of the cleaning device brush head.

[0141] Along the first direction X, the distance from both sides of the first structural part 231 to the middle of the first structural part 231, and from the outer edge 234 of the first structural part 231 to the center line extending along the first direction X of the roller brush 2, can gradually decrease. This configuration, compared to the previous embodiment, further improves the guiding ability of the support strip 23, ensuring a better guiding effect on impurities such as hair and cotton threads, and further improves the cleaning effect of the cleaning device brush head.

[0142] In one embodiment, there may be a gap between the end of the teeth 31 near the roller brush 2 and the support bar 23. This arrangement can prevent friction between the teeth 31 and the support bar 23, thus avoiding noise generated by friction and improving the quietness of the cleaning device brush head. When there is no friction between the teeth 31 and the support bar 23, wear on the support bar 23 can also be avoided, extending the service life of the roller brush 2.

[0143] In another embodiment, the end of the tooth 31 near the roller brush 2 can contact the surface of the support strip 23. It should be noted that "contact" here means that the end of the tooth 31 near the roller brush 2 is just touching the surface of the support strip 23, at which point there is no interference and no interaction force between the tooth 31 and the support strip 23. This arrangement allows the tooth 31 to contact hair, cotton threads, and other cleaning impurities adsorbed on the support strip 23, thereby hooking and dispersing these impurities, improving the cleaning effect of the tooth 31 and enhancing the anti-tangling ability of the cleaning device brush head. Simultaneously, because there is no interference and no interaction force between the tooth 31 and the support strip 23, there is also little friction between the tooth 31 and the roller brush 2, resulting in minimal noise and allowing the cleaning device brush head to also achieve good quiet operation.

[0144] In another embodiment, the end of the tooth 31 near the roller brush 2 can interfere with the support bar 23. That is, it can be understood that there can be interference and interaction forces between the end of the tooth 31 near the roller brush 2 and the support bar 23. This arrangement can improve the success rate of the tooth 31 in hooking onto hair, cotton thread, and other impurities on the surface of the support bar 23, thereby further improving the cleaning effect of the tooth 31 and giving the brush head of the cleaning device better anti-tangling ability.

[0145] In one embodiment of this disclosure, the hardness of the support strip 23 can be greater than that of the cleaning brush 22 to ensure the support effect of the support strip 23. The material of the support strip 23 can be soft rubber, but is not limited to this. The material of the support strip 23 can be hard rubber, etc., and can be selected and set according to actual needs, all of which are within the protection scope of this disclosure.

[0146] This disclosure also 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, floor scrubber, or robotic vacuum cleaner, etc. The cleaning device brush head may be one of the cleaning device brush heads described above, and the cleaning device body may be connected to the cleaning device brush head.

[0147] It should be noted that the specific structure and beneficial effects of the cleaning device brush head have been described in detail in the previous embodiment. Therefore, in this embodiment, the specific structure and beneficial effects of the cleaning device brush head will not be described again. Please refer to the specific description in the previous embodiment, which is within the protection scope of this disclosure.

[0148] The cleaning equipment provided in this disclosure includes the cleaning equipment brush head described above, such as... Figures 1 to 10 As shown, the cleaning device brush head described above may include: a main body 1, a roller brush 2, and comb teeth 3. The roller brush 2 may be disposed on the main body 1 and is rotatable relative to the main body 1; the comb teeth 3 may be mounted on the main body 1 for removing dirt from the roller brush 2. The comb teeth 3 may include a plurality of teeth 31 arranged along a first direction X, and at least some of the teeth 31 may have a first acute angle α between their extending 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.

[0149] Therefore, when the roller brush 2 is rotating, the inclined teeth 31 can hook and disperse the hair, cotton thread and other cleaning impurities wrapped around the roller brush 2, and the airflow in the suction port 11 can directly suck the dispersed hair, cotton thread and other cleaning impurities into the air duct.

[0150] Therefore, the cleaning equipment brush head provided in this disclosure has good anti-tangling ability, which can effectively avoid the problem of hair, cotton thread, and other cleaning impurities constantly tangling on the roller brush 2, thus affecting the normal operation of the cleaning equipment brush head. Furthermore, the cleaning equipment brush head can promptly draw hair, cotton thread, and other cleaning impurities into the air duct, thereby improving the cleaning ability and cleaning effect of the brush head, and consequently improving the cleaning ability and cleaning effect of the cleaning equipment.

[0151] This disclosure also provides a cleaning system. The cleaning system may include a base station and cleaning equipment. The cleaning equipment may be the cleaning equipment described above, and the cleaning equipment is capable of interfacing with the base station.

[0152] It should be noted that the specific structure and beneficial effects of the cleaning equipment have been described in detail in the previous embodiment. Therefore, the specific structure and beneficial effects of the cleaning equipment will not be described again in this embodiment. Please refer to the specific description in the previous embodiment. All of these are within the protection scope of this disclosure.

[0153] The cleaning system provided in this disclosure includes the cleaning equipment described above, and the cleaning equipment includes a cleaning equipment brush head, such as... Figures 1 to 10As shown, the cleaning device brush head may include: a main body 1, a roller brush 2, and comb teeth 3. The roller brush 2 may be disposed on the main body 1 and is rotatable relative to the main body 1; the comb teeth 3 may be mounted on the main body 1 for removing dirt from the roller brush 2. The comb teeth 3 may include a plurality of teeth 31 arranged along a first direction X, and at least some of the teeth 31 may have a first acute angle α between their extending 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.

[0154] Therefore, when the roller brush 2 is rotating, the inclined teeth 31 can hook and disperse the hair, cotton thread and other cleaning impurities wrapped around the roller brush 2, and the airflow in the suction port 11 can directly suck the dispersed hair, cotton thread and other cleaning impurities into the air duct.

[0155] Therefore, the cleaning equipment brush head provided in this disclosure has good anti-tangling ability, which can effectively avoid the problem of hair, cotton thread, and other cleaning impurities constantly tangling on the roller brush 2, thus affecting the normal operation of the cleaning equipment brush head. Furthermore, the cleaning equipment brush head can promptly draw hair, cotton thread, and other cleaning impurities into the air duct, thereby improving the cleaning ability and effect of the cleaning equipment brush head, and consequently improving the cleaning ability and effect of the cleaning system.

[0156] In one embodiment, when the cleaning device is connected to the base station, the base station can charge the cleaning device, and / or, when the cleaning device is connected to the base station, the base station can suck out the dirt stored in the cleaning device and clean the cleaning device, etc.
