[0002] Existing cleaning devices mainly include sweepers, floor washers, or base stations with sweepers or floor washers. Some sweepers or floor washers are equipped with cleaning brushes at the bottom for cleaning the floor or carpet.

[0003] For existing cleaning brushes, due to no special treatment on the cleaning brush, there are problems such as excessive noise when cleaning the floor and poor cleaning effect when cleaning the carpet. Summary of the Utility Model

[0004] The main purpose of this application is to provide a cleaning brush and a cleaning device to at least solve the problems of excessive noise when the existing cleaning brush cleans the floor and poor cleaning effect when the cleaning brush cleans the carpet.

[0005] According to one aspect of this application, a cleaning brush is provided, including:

[0006] A brush body that can rotate around its own axial direction;

[0007] At least one first blade, and at least one of the first blades is arranged on the outer periphery of the brush body;

[0008] At least one second blade, and at least one of the second blades is arranged on the outer periphery of the brush body;

[0009] Wherein, the maximum height A of the first blade protruding from the outer surface of the brush body is higher than the maximum height B of the second blade protruding from the outer surface of the brush body; when the cleaning brush is used to clean a hard surface, the first blade contacts the hard surface, and there is a predetermined height between the second blade and the hard surface; when the cleaning brush is used to clean a flexible surface, both the first blade and the second blade contact the flexible surface.

[0010] Further, a thinning groove is provided on the first blade, and the thinning groove extends along the length direction of the first blade.

[0011] Further, the relationship between the maximum height A of the first blade protruding from the outer surface of the brush body and the maximum height B of the second blade protruding from the outer surface of the brush body satisfies the relation: 1.08 ≤ A / B ≤ 1.16.

[0012] Further, the relationship between the thickness C of the first blade and the thickness D of the second blade satisfies the relation: 1.4 ≤ D / C ≤ 2.15.

[0013] Further, a convex section is provided at one end of the first blade away from the brush body, and the convex section protrudes a predetermined length along the first side or the second side of the first blade.

[0014] Further, along the direction away from the first blade, the thickness E of the convex section gradually decreases.

[0015] Further, the brush body includes:

[0016] A main body, the first blade and the second blade are arranged on the outer periphery of the main body, and a through hole is provided inside the main body;

[0017] A rotating shaft, the rotating shaft is arranged in the through hole;

[0018] A flexible support body, the flexible support body is filled between the main body and the rotating shaft.

[0019] Further, a dirt storage groove is provided at at least one end in the axial direction of the brush body.

[0020] Further, there are n first blades, n ∈ N+, and there are m second blades, m ∈ N+, and m ≤ n;

[0022] On the other hand, the present application also provides a cleaning device, and the cleaning device includes the above-mentioned cleaning brush.

[0023] Compared with the prior art, when the cleaning brush cleans a hard surface, such as the ground, since the maximum height A of the first blade protruding from the outer surface of the brush body is higher than the maximum height B of the second blade protruding from the outer surface of the brush body, the second blade will not contact the ground. Therefore, the contact area between the brush body and the ground is reduced, thereby reducing the noise generated between the cleaning brush and the ground. When the cleaning brush cleans a flexible surface, such as a blanket, since the texture of the blanket is soft and the cleaning brush sinks into the blanket, the second blade comes into contact with the blanket, and both the first blade and the second blade will clean the blanket, thereby improving the cleaning efficiency of the cleaning brush for the blanket.

It should be noted that like reference numerals and letters denote like items in the following drawings, and thus, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0037] Referring to Figures 1 to 7 As shown, according to an embodiment of the present application, a cleaning brush is provided, which includes a brush body 10, a first blade 20, and a second blade 30.

[0038] Among them, the brush body 10 can rotate around its own axial direction. The first blade 20 includes at least one, and at least one first blade 20 is arranged on the outer periphery of the brush body 10. The second blade 30 includes at least one, and at least one second blade 30 is arranged on the outer periphery of the brush body 10. Wherein, the maximum height A of the first blade 20 protruding from the outer surface of the brush body 10 is higher than the maximum height B of the second blade 30 protruding from the outer surface of the brush body 10; when the cleaning brush is used to clean a hard surface, the first blade 20 contacts the hard surface, and there is a predetermined height between the second blade 30 and the hard surface. When the cleaning brush is used to clean a flexible surface, both the first blade 20 and the second blade 30 contact the flexible surface.

[0039] Specifically, after the brush body 10 rotates, it drives the first blade 20 and the second blade 30 to rotate. After the first blade 20 and the second blade 30 come into contact with the surface to be cleaned, the stain on the surface to be cleaned is scraped off by the first blade 20 or the second blade 30 under the action of friction, thereby cleaning the surface to be cleaned.

[0040] In this embodiment, when the cleaning brush cleans a hard surface, such as the ground, since the maximum height A of the first blade 20 protruding from the outer surface of the brush body 10 is higher than the maximum height B of the second blade 30 protruding from the outer surface of the brush body 10, the second blade 30 will not contact the ground. Therefore, the contact area between the brush body 10 and the ground is reduced, thereby reducing the noise generated between the cleaning brush and the ground. When the cleaning brush cleans a flexible surface, such as a blanket, since the texture of the blanket is soft, the cleaning brush sinks into the blanket, so that the second blade 30 contacts the blanket, and both the first blade 20 and the second blade 30 will clean the blanket, thereby improving the cleaning efficiency of the cleaning brush for the blanket.

[0041] In addition, in this embodiment, the first blade 20 is inclined at a predetermined angle and extends along the axis direction of the brush body 10, and the second blade 30 is inclined at a predetermined angle and extends along the axis direction of the brush body 10. Moreover, the heights from each part of the end face of the first blade 20 and the second blade 30 far from the brush body 10 to the outer surface of the brush body 10 are the same. While increasing the acting time of the first blade 20 and the second blade 30 on the surface to be cleaned, it is avoided that when the heights from each part of the end face of the first blade 20 and the second blade 30 far from the brush body 10 to the outer surface of the brush body 10 are different, the brush body 10 bumps during rotation, thereby affecting the cleaning effect of the cleaning brush.

[0042] As shown in the attached Figure 3 figure, a thinning groove 21 is provided on the first blade 20, and the thinning groove 21 extends along the length direction of the first blade 20.

[0043] In a specific embodiment, the hardness of the first blade 20 is set to be the same as that of the second blade 30. The hardness of both the first blade 20 and the second blade 30 is 60 HB to 80 HB, preferably 80 HB. In this embodiment, a thinning groove 21 extending along the length direction of the first blade 20 is provided on the first blade 20. The setting of the thinning groove 21 reduces the hardness of the first blade 20 to a certain extent, thereby avoiding the problem that the first blade 20 scratches the surface to be cleaned due to excessive hardness or the problem that when the hardness of both the first blade 20 and the surface to be cleaned is too high, mechanical collision between the first blade 20 and the surface to be cleaned causes damage to the first blade 20. In one embodiment, the thinning groove 21 is opened in the middle of the first blade 20, dividing the first blade 20 into a bendable section and a non-bendable section. The bendable section is located on the side of the first blade 20 far from the brush body 10. When the bendable section contacts the surface to be cleaned, it is subjected to the acting force of the surface to be cleaned and can be bent at a certain angle, thereby avoiding rigid contact between the first blade 20 and the surface to be cleaned, resulting in the surface to be cleaned being scratched or the first blade 20 being damaged.

[0044] Furthermore, the maximum height A of the first blade 20 protruding from the outer surface of the brush body 10 and the maximum height B of the second blade 30 protruding from the outer surface of the brush body 10 satisfy the relational expression: 1.08 ≤ A / B ≤ 1.16. When A and B satisfy the above relational expression, the difference between A and B is small, which can, to a certain extent, prevent the second blade 30 from failing to contact the flexible surface when the cleaning brush cleans the flexible surface; the difference between A and B is not too small, either, which may cause the second blade 30 to directly contact the hard surface when the cleaning brush cleans the hard surface. When A / B is less than 1.08, the difference between A and B is small, so that when the cleaning brush cleans the hard surface, the second blade 30 may contact the hard surface, thereby increasing the noise generated during cleaning; when A / B is greater than 1.16, the difference between A and B is large, which may cause the second blade 30 to fail to contact the flexible surface when the cleaning brush cleans the flexible surface, thereby reducing the cleaning effect of the cleaning brush. The value of A / B can be 1.08, 1.09, 1.1, 1.11, 1.12, 1.13, 1.14, 1.15, and 1.16.

[0045] Furthermore, the thickness C of the first blade 20 and the thickness D of the second blade 30 satisfy the relational expression: 1.4 ≤ D / C ≤ 2.15.

[0046] Specifically, since the first blade 20 is longer and the second blade 30 is shorter, if the hardness of the first blade 20 is the same as that of the second blade 30, it may cause the first blade 20 to have a rigid contact with the surface to be cleaned during cleaning, so that the first blade 20 is easily damaged. Therefore, in this embodiment, the hardness of the first blade 20 and the second blade 30 is changed by changing the thickness C of the first blade 20 and the thickness D of the second blade 30. The hardness of the second blade 30 is usually set to 80 HB. When C and D satisfy the relational expression: 1.4 ≤ D / C ≤ 2.15, the hardness of the first blade 20 is lower than that of the second blade 30, and the thickness of the first blade 20 is appropriate, thereby preventing the first blade 20 from being easily pierced due to its too thin thickness; at the same time, it avoids the second blade 30 having too thick a thickness, which may cause the first blade 20 to lean against the second blade 30 after being bent. When D / C is less than 1.4, the thickness of the first blade 20 is too thin, and the first blade 20 is easily damaged under the action of external force. When D / C is greater than 2.15, the thickness of the second blade 30 is too thick, which may cause interference between the second blade 30 and the first blade 20, ultimately affecting the cleaning effect of the cleaning brush. The value of D / C can be 1.4, 1.5, 1.6, 1.7, 1.8, 1.9, 2, 2.1, and 2.15.

[0047] In addition, a convex section 22 is provided at one end of the first blade 20 away from the brush body 10, and the convex section 22 protrudes a predetermined length along the first side or the second side of the first blade 20.

[0048] Specifically, after the first blade 20 scrapes up the stains on the surface to be cleaned, the raised section 22 can carry away the stains, thereby improving the cleaning effect of the cleaning brush. Similarly, a raised section 22 can also be provided at one end of the second blade 30 away from the brush body 10, so that after the second blade 30 scrapes off the stains on the surface to be cleaned, the raised section 22 can carry away the stains.

[0049] Further, along the direction away from the first blade 20, the thickness E of the raised section 22 gradually decreases.

[0050] In this embodiment, the raised section 22 is wedge-shaped. The end of the raised section 22 away from the first blade 20 is the wedge top, and the end of the raised section 22 close to the first blade 20 is the wedge bottom. When the raised section 22 contacts the stains, due to the smaller contact area between the wedge top and the stains, the raised section 22 can more easily shovel up the stains and carry them away, thereby further improving the cleaning effect of the cleaning brush.

[0051] As shown in the Figure 4 and the Figure 7 accompanying drawings, the brush body 10 includes a main body 11, a rotating shaft 12, and a flexible support body 13. Among them, the first blade 20 and the second blade 30 are arranged on the outer periphery of the main body 11. A through hole 110 is formed inside the main body 11, the rotating shaft 12 is inserted into the through hole 110, and the flexible support body 13 is filled between the main body 11 and the rotating shaft 12.

[0052] In this embodiment, the main body 11, the first blade 20, and the second blade 30 are integrally formed, and the main body 11, the first blade 20, and the second blade 30 are all colloids. The rotating shaft 12 is inserted into the through hole 110, and the rotating shaft 12 rotates to drive the main body 11 to rotate. The flexible support body 13 is arranged between the main body 11 and the rotating shaft 12. The flexible support body 13 is used to prevent the first blade 20 from being damaged when the cleaning brush cleans a hard floor. Specifically, when the support force exerted by the hard floor on the first blade 20 is too large, the first blade 20 transfers the external force to the flexible support body 13, and the flexible support body 13 absorbs the external force, thereby preventing the first blade 20 from being damaged due to excessive stress. In this embodiment, the flexible support body 13 can be a foam support body or a silicone support body.

[0053] Further, a dirt storage groove 40 is provided at at least one end in the axial direction of the brush body 10.

[0054] In a specific embodiment, dirt storage grooves 40 are formed at both ends of the brush body 10 in the axial direction. The dirt storage grooves 40 extend a predetermined distance in the direction close to the inside of the brush body 10. Specifically, when filling the flexible support 13, the flexible support 13 is not filled at both ends of the main body 11, so that a dirt storage groove 40 is formed by enclosing the inner wall surface of the main body 11, the flexible support 13 and the rotating shaft 12. In this embodiment, the dirt storage groove 40 is used to collect dirt such as hair or lint. That is, when the cleaning brush rotates, due to the dirt storage grooves 40 provided at both ends of the main body 11, after the hair or lint is wound around the rotating shaft 12, the hair or lint is gradually brought into the dirt storage groove 40 under the action of the cleaning brush. After the cleaning brush finishes cleaning, only the hair or lint in the dirt storage groove 40 needs to be removed to complete the cleaning of the hair or lint, thereby preventing the hair or lint from winding around the first blade 20 or the second blade 30 and further affecting the cleaning effect of the cleaning brush. Of course, the dirt storage groove 40 may also be formed only at one end of the brush body 10 in the axial direction.

[0055] In addition, the first blade 20 includes n pieces, where n ∈ N + , and the second blade 30 includes m pieces, where m ∈ N + , and m ≤ n; the m second blades 30 and the n first blades 20 are alternately arranged in sequence along the circumferential direction of the brush body 10.

[0056] Specifically, in this embodiment, the number of the first blades 20 should be greater than or equal to the number of the second blades 30. If the number of the first blades 20 is too small, the cleaning effect of the cleaning brush on the ground may be poor, while if the number of the second blades 30 is too large, the first blade 20 may interfere with the second blade 30 when being bent. In addition, the fact that the m second blades 30 and the n first blades 20 are alternately arranged in sequence along the circumferential direction of the brush body 10 means that, for example, when there are 5 second blades 30 and 5 first blades 20, the 5 second blades 30 and the 5 first blades 20 are alternately arranged in sequence, or when there are 10 first blades 20 and 5 second blades 30, there are two first blades 20 between two adjacent second blades 30, or when there are 6 first blades 20 and 5 second blades 30, the 5 first blades 20 and the 5 second blades 30 are alternately arranged in sequence, and the remaining one first blade 20 is arranged between the first blade 20 and the second blade 30.

[0057] It is worth mentioning that increasing the number of the first blades 20 will increase the frictional force between the first blades 20 and the surface to be cleaned, thereby increasing the noise generated during the cleaning of the cleaning brush. If the number of the first blades 20 is small, the cleaning power of the cleaning brush will be too low to meet the cleaning effect of the cleaning brush. Therefore, after comprehensively considering the relationship between noise and cleaning power, in this embodiment, both the first blades 20 and the second blades 30 are five in number, and the five first blades 20 and the five second blades 30 are alternately arranged in sequence along the circumferential direction of the outer periphery of the brush body 10.

[0058] On the other hand, the present application also provides a cleaning device, which includes the cleaning brush in the above embodiment. Therefore, the cleaning device includes all the technical effects of the cleaning brush in the above embodiment. Since the technical effects of the cleaning brush have been described in detail above, they will not be elaborated here.

[0059] In summary, the present application provides a cleaning brush and a cleaning device. The maximum height A of the first blade 20 protruding from the outer surface of the brush body 10 is higher than the maximum height B of the second blade 30 protruding from the outer surface of the brush body 10. When the cleaning device cleans a hard surface such as the ground, only the first blade 20 can contact the ground, thereby reducing the noise generated during the cleaning of the cleaning device. When cleaning a flexible surface such as a blanket, both the first blade 20 and the second blade 30 can clean the blanket, thereby improving the cleaning effect of the cleaning device on the flexible surface. In addition, a thinning groove 21 is formed in the first blade 20 to reduce the hardness of the first blade 20 and avoid rigid contact between the first blade 20 and the ground, thereby prolonging the service life of the first blade 20. Secondly, in the present application, the relationship between the maximum height A of the first blade 20 protruding from the outer surface of the brush body 10 being higher than the maximum height B of the second blade 30 protruding from the outer surface of the brush body 10 is defined, and the widths of the first blade 20 and the second blade 30 are defined to prevent the first blade 20 from being damaged or the second blade 30 from interfering with the first blade 20. Finally, a dirt storage groove 40 is formed at least at one end in the axial direction of the cleaning brush, so that when the cleaning device is cleaning, hair or lint can be collected in the dirt storage groove 40, thereby avoiding the hair or lint from winding around the first blade 20 or the second blade 30 and affecting the cleaning effect of the cleaning device.

[0060] For ease of description, spatial relative terms, such as "above", "over", "on the upper surface", "upper", etc., may be used herein to describe the spatial positional relationship of one device or feature to other devices or features as shown in the figures. It should be understood that the spatial relative terms are intended to encompass different orientations in use or operation in addition to the orientation depicted in the figures.
