Description

TECHNICAL FIELD

[0002] With the development of science and technology, cleaning devices have become more and more popular, and most of the cleaning devices clean the ground through a cleaning roller brush. With the rotation of the cleaning roller brush, a dust lifting assembly on the cleaning roller brush can lift the dust, hair and other debris on the cleaning surface, so that the fan in the cleaning device can suck the debris into the dust box. During the cleaning process, the hair-like linear debris on the ground is easy to wrap around the outer circumference of the cleaning roller brush, and the wrapping material can affect the cleaning function of the cleaning roller brush, and in severe cases, the wrapping material can also cause the cleaning roller brush to stop and damage the cleaning device.

However, if the cutting region of the cutting assembly is long, the continuity of the dust lifting assembly will be reduced, resulting in poor cleaning effect of the cleaning device; if the cutting region of the cutting assembly is short, the cutting efficiency of the cutting assembly will be reduced, resulting in the wrapping of linear debris on the cleaning roller brush, thereby affecting the normal work of the cleaning device.

DETAILED DESCRIPTION

[0033] In order to make the objects, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are merely intended to explain the present application and not to limit the present application.

[0034] It should be noted that when an element is referred to as being "fixed" or "disposed" on another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or indirectly connected to the other element.

[0035] In addition, the terms "first", "second", "third", etc. are used only to describe purposes and can not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "a plurality of" is two or more, unless otherwise specifically limited.

[0036] In the present application, the reference "one embodiment", "some embodiments" or "embodiments" described in the specification means that the specific features, structures or characteristics described in connection with the embodiment are included in one or more embodiments of the present application. Therefore, the statements "in one embodiment", "in some embodiments", "in other some embodiments", "in other some embodiments" and the like appearing in different places in the specification are not necessarily all referring to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized. In addition, in one or more embodiments, specific features, structures or characteristics can be combined in any suitable manner.

[0037] With the development of science and technology, cleaning equipment has become more and more popular, and most of the cleaning equipment cleans the ground through a cleaning roller brush. With the rotation of the cleaning roller brush, the dust lifting assembly on the cleaning roller brush can lift the dust, hair and other debris on the cleaning surface, so that the fan in the cleaning equipment can suck the debris into the dust box. During the cleaning process, the hair-like linear debris on the ground is easy to wrap around the outer circumference of the cleaning roller brush, and the wrapping material will affect the cleaning function of the cleaning roller brush, and in severe cases, the wrapping material will also cause the cleaning roller brush to stop and cause damage to the cleaning equipment.

[0038] In the related art, a cutting assembly is arranged at the middle of the cleaning roller brush, and the cutting assembly is movable relative to the cleaning roller brush in the axial direction of the cleaning roller brush to cut the winding objects on the cleaning roller brush, thereby reducing the influence of the winding objects on the cleaning roller brush. However, if the cutting region (i.e., the range in which the cutting assembly can cut the winding objects) of the cutting assembly is long, the continuity of the dust lifting assembly is reduced, and the cleaning effect of the cleaning device is poor. If the cutting region of the cutting assembly is short, the cutting efficiency of the cutting assembly is reduced, and the winding linear objects on the cleaning roller brush affect the normal work of the cleaning device.

[0039] In view of the above problems, the present application provides a cleaning roller brush, a cleaning device and a cleaning system, aiming to solve the technical problem that the cleaning effect of the cleaning device and the cutting efficiency of the cutting assembly cannot be balanced.

[0040] In order to illustrate the technical solutions of the present application, the specific embodiments and drawings will be described below.

[0041] Please refer to Figure 1 and Figure 3 The present application provides a cleaning roller brush, which comprises a shell 1, a dust lifting assembly 2 and a cutting assembly 3.

[0042] The shell 1 is provided with a cutting portion 11, the length of the cutting portion 11 in the axial direction of the shell 1 is one-sixteenth to one-half of the total length of the shell 1 in the axial direction, and a cutting groove 12 is arranged on the cutting portion 11; the dust lifting assembly 2 is mounted on the outer circumferential surface of the shell 1, and the dust lifting assembly 2 extends from one end to the other end of the shell 1 in the axial direction; the cutting assembly 3 is arranged in the shell 1, and the cutting knife 31 of the cutting assembly 3 is arranged in the cutting groove 12 and is movable relative to the cutting portion 11 to cut the winding objects wound on the cutting portion 11.

[0043] It should be noted that the cleaning principle of the cleaning device is that the cleaning roller brush rolls relative to the cleaning surface, the dust lifting assembly 2 on the rolling cleaning roller brush scrapes or fans the objects on the cleaning surface to lift the objects on the cleaning surface, and the fan of the cleaning device generates suction to suck the lifted objects into the dust box. During the rolling process of the cleaning roller brush, whether the dust lifting assembly 2 effectively lifts the objects is one of the important factors affecting the cleaning effect of the cleaning device. When the continuity of the dust lifting assembly 2 is poor, the dust lifting assembly 2 cannot always be in contact with the cleaning surface or the dust lifting assembly 2 cannot always fan on the cleaning surface during the rolling process of the cleaning roller brush, so that the dust lifting assembly 2 cannot effectively lift the objects, resulting in poor cleaning effect of the cleaning device.

[0044] In the cleaning roller brush provided with the cutting assembly 3, a cutting groove 12 is needed to be opened on the shell 1 to accommodate the cutting knife 31 of the cutting assembly 3, the cutting knife 31 cuts the winding material wound on the cutting part 11 at the opening of the cutting groove 12, and the dust raising assembly 2 needs to avoid the cutting groove 12; when the length of the cutting groove 12 on the cleaning roller brush is longer, the cutting area of the cutting assembly 3 is longer, and the cutting efficiency is higher, but the length reserved on the cleaning roller brush for arranging the dust raising assembly 2 is reduced, which leads to poor continuity of the dust raising assembly 2, so that the dust raising assembly 2 cannot be in contact with the cleaning surface all the time or the dust raising assembly 2 cannot always fan on the cleaning surface in the process of rolling the cleaning roller brush, which causes part of the dirt on the cleaning surface to be unable to be raised, thereby affecting the cleaning effect of the cleaning equipment.

[0045] However, in the cleaning roller brush provided by the present application, the upper limit of the length of the cutting knife 31 is determined by the length of the cutting part 11, by limiting the length of the cutting part 11 in the axial direction of the shell 1 to be between one-sixteenth and one-half of the total length in the axial direction of the shell 1, and by extending the dust raising assembly 2 from one end in the axial direction of the shell 1 to the other end in the axial direction of the shell 1, the length of the cutting knife 31 can be as long as possible without affecting the continuity of the dust raising assembly 2, so that the cutting efficiency of the cutting assembly 3 can be improved without affecting the cleaning effect of the cleaning equipment provided with the cleaning roller brush of the embodiments of the present application, and the cutting efficiency of the cutting assembly 3 and the cleaning effect of the cleaning equipment can be balanced.

[0046] Optionally, in some embodiments, the length of the cutting part 11 in the axial direction of the shell 1 is 10-100 mm.

[0047] It should be noted that the side wall of the cutting groove 12 has a certain thickness, which is defined as L 厚 Therefore, the length (L 切割槽 ) of the cutting groove 12 in the axial direction of the shell 1 is less than the length (L 切割部 ) of the cutting part 11, and L 切割槽 =L 切割部 -L 厚 .

[0048] It should be noted that the thickness of the side wall of the cutting groove 12 can be selected according to actual needs.

[0049] Please refer to Figure 1 In some embodiments, the cutting part 11 is arranged at the middle part in the axial direction of the shell 1, so that the cleaning roller brush is suitable for the cleaning equipment with the suction port at the middle part.

[0050] Please refer to Figure 1In some embodiments, the dust lifting assembly 2 comprises a dust lifting strip 21, the dust lifting strip 21 comprises a first sub-portion 211 and a second sub-portion 212 connected to each other, an end of the first sub-portion 211 away from the second sub-portion 212 is located at one end of the housing 1, an end of the second sub-portion 212 away from the first sub-portion 211 is located at the other end of the housing 1, and the end of the first sub-portion 211 away from the second sub-portion 212 and the end of the second sub-portion 212 away from the first sub-portion 211 are both located at the same side of the connection between the first sub-portion 211 and the second sub-portion 212.

[0051] In the above embodiments, the dust lifting strip 21 forms a funnel-shaped space, so that the dust lifting strip 21 can effectively lift the sundries on one side of the dust lifting strip 21 when the cleaning roller brush rotates.

[0052] Please refer to Figure 6 In some embodiments, on the circumference of the housing 1, the connection between the first sub-portion 211 and the second sub-portion 212 is located at one side of the cutting portion 11, the end of the first sub-portion 211 away from the second sub-portion 212 is located at one end of the housing 1, the end of the second sub-portion 212 away from the first sub-portion 211 is located at the other end of the housing 1, and the end of the first sub-portion 211 away from the second sub-portion 212 and the end of the second sub-portion 212 away from the first sub-portion 211 are both located at the other side of the cutting portion 11.

[0053] By adopting the above technical solution, the dust lifting strip 21 forms a funnel-shaped space, the cutting portion 11 is located in the funnel-shaped space formed by the dust lifting strip 21, and the dust lifting strip 21 can guide the winding objects to the cutting portion 11 when the cleaning roller brush rotates.

[0054] Please refer to Figure 6 In some embodiments, the first sub-portion 211 and the second sub-portion 212 are spirally arranged, and the first sub-portion 211 and the second sub-portion 212 have opposite rotation directions, so that the dust lifting strip 21 can guide the linear sundries to the connection between the first sub-portion 211 and the second sub-portion 212 when the cleaning roller brush rotates.

[0055] Since the first sub-part 211 and the second sub-part 212 are opposite in rotation direction, in the process of synchronously rotating the dust lifting strip 21 with the shell 1, the first sub-part 211 and the second sub-part 212 are opposite in the guiding direction of the winding, the winding on the shell 1 can be guided to the connection position of the first sub-part 211 and the second sub-part 212, so that the winding on other positions of the shell 1 can be moved to the middle area of the shell 1 as much as possible, and the connection position of the first sub-part 211 and the second sub-part 212 is located at one side of the cutting part 11, so that the winding on other positions of the shell 1 can be moved to the cutting part 11 under the guidance of the dust lifting strip 21. In this way, only one set of cutting assembly 3 can be arranged on the shell 1, and the winding on other positions of the shell 1 can be guided to the cutting assembly 3 by the dust lifting strip 21, so that the number of cutting assemblies 3 can be reduced, and the cost can be reduced.

[0056] In the process of driving the cleaning brush to rotate by the cleaning device, the winding will rotate with the shell 1 and wind around the outer circumferential surface of the shell 1, and the winding will wind around different positions of the shell 1, and the position of the cutting part 11 is fixed, so that the cutting assembly 3 at the cutting part 11 can only cut the winding on the cutting part 11. The first sub-part 211 and the second sub-part 212 can guide the winding to the cutting part 11, so that the winding wound around different positions of the shell 1 can be guided into the cutting area of the cutting assembly 3, so that the cutting assembly 3 can cut the winding, so as to avoid the winding on the shell 1 as much as possible, reduce the influence of the winding on the cleaning brush, improve the working effect of the cleaning brush, and improve the service life of the cleaning brush.

[0057] Please refer to Figure 6 In some embodiments, the dust lifting assembly 2 further comprises a guide strip 22, the guide strip 22 comprises a first guide part 221 and a second guide part 222, and in the axial direction of the shell 1, the first guide part 221 and the second guide part 222 are arranged at intervals, the cutting part 11 is located between the first guide part 221 and the second guide part 222, the end of the first guide part 221 away from the second guide part 222 is located at one end of the shell 1, the end of the second guide part 222 away from the first guide part 221 is located at the other end of the shell 1, the first guide part 221 and the second guide part 222 are spirally arranged, and the spiral directions of the first guide part 221 and the second guide part 222 are opposite.

[0058] Since the first guide part 221 and the second guide part 222 are opposite in rotation direction, the guide directions of the first guide part 221 and the second guide part 222 to the winding object are opposite in the process of synchronous rotation of the guide strip 22 and the shell 1, the winding object on the shell 1 can be guided to the middle region of the shell 1, so that the winding object at other positions on the shell 1 can move to the middle region of the shell 1 as much as possible, and the cutting part 11 is arranged between the first guide part 221 and the second guide part 222, so that the winding object at other positions on the shell 1 can be guided to the cutting part 11 under the guidance of the guide strip 22.

[0059] Please refer to Figure 6 In some embodiments, the cleaning roller brush further comprises a guide brush 23, the guide brush 23 is installed on the shell 1, and the guide brush 23 is used to guide the winding object to the cutting part 11. Compared with the guide strip 22, the guide brush 23 is easier to guide the winding object, thereby reducing the difficulty of guiding the winding object, so that the winding object is more easily guided into the cutting region of the cutting assembly 3, and the risk of the winding object being wound on the guide strip 22 is reduced, thereby reducing the influence of the winding object on the working of the cleaning roller brush.

[0060] Please refer to Figure 6 In some embodiments, the guide brush 23 is arranged on both sides of the guide strip 22, and each guide brush 23 has a plurality of bristles, and the bristles are spirally arranged along the spiral direction of the guide strip 22. Under the double action of the guide brush 23 and the guide strip 22, the guiding effect on the winding object is improved, so that the winding object at different positions of the shell 1 can be guided to the cutting assembly 3 as much as possible, thereby reducing the risk of the winding object being wound on the guide strip 22, and thereby reducing the influence of the winding object on the working of the cleaning roller brush.

[0061] In some embodiments, the dust raising assembly 2 is arranged to always maintain a preset distance from the cleaning surface in the working state of the cleaning device, that is, when the cleaning device is working, the dust raising assembly 2 can always maintain a preset distance from the cleaning surface with the rotation of the cleaning roller brush.

[0062] By adopting the above technical scheme, when the cleaning device is working, the dust raising assembly 2 on the cleaning roller brush can always contact the cleaning surface or the distance between the dust raising assembly 2 on the cleaning roller brush and the cleaning surface is maintained at a preset distance, so as to reduce the noise generated when the cleaning device is working.

[0063] Please refer to Figure 1 and Figure 2In some embodiments, the shell 1 comprises two half shells 13, each of which is provided with a half hole 131, and each of which is provided with a protrusion 132, the protrusion 132 is provided with a receiving channel 1321 which is in communication with the half hole 131, the two half shells 13 are spliced by threaded fasteners to form the shell 1, and the half holes 131 of the two half shells 13 enclose a cavity, the protrusions 132 of the two half shells 13 are spliced to form the cutting part 11, and the receiving channels 1321 of the two half shells 13 are opposite and enclose a cutting groove 12 which is in communication with the cavity and the outside space, and the cutting assembly 3 is arranged in the cavity, and part of the cutting assembly is movably arranged between the two protrusions 132.

[0064] For reference Figure 1 Optionally, in some embodiments, the shell 1 is provided with two dust lifting strips 21, one of which is arranged on each of the half shells 13, and the connection between the first sub-part 211 and the second sub-part 212 of the dust lifting strip 21 is located on one side of the protrusion 132, and the two ends of the dust lifting strip 21 extend to the connection between the two half shells 13. When the cleaning device is working, the dust lifting strip 21 on the cleaning roller brush can always contact the cleaning surface or the distance between the dust lifting strip 21 on the cleaning roller brush and the cleaning surface remains unchanged.

[0065] For reference Figure 6 In some embodiments, the shell 1 is provided with two dust lifting strips 21 and two guide strips 22, the connection between the first sub-part 211 and the second sub-part 212 of the dust lifting strip 21 is located on one side of the protrusion 132 on one of the half shells 13, and the dust lifting strip 21 extends to the other half shell 13 through the connection between the two half shells 13 after passing around the protrusion 132, and one of the dust lifting strips 21 is arranged on each of the half shells 13. When the cleaning device is working, the dust lifting strip 21 or the guide strip 22 on the cleaning roller brush can contact the cleaning surface or the distance between the dust lifting strip 21 or the guide strip 22 on the cleaning roller brush and the cleaning surface is a predetermined distance.

[0066] According to the design requirements of the cleaning device, in some embodiments, the dust lifting assembly 2 is in interference with the cleaning surface when the cleaning device is placed on the cleaning surface (such as the ground), that is, the dust lifting assembly 2 can always maintain a predetermined distance from the cleaning surface with the rotation of the cleaning roller brush, which means that the dust lifting assembly 2 can always contact the cleaning surface.

[0067] In the above embodiments, the dust lifting assembly 2 always contacts the cleaning surface can prevent impurities from leaking between the dust lifting assembly 2 and the cleaning surface, thereby enhancing the cleaning efficiency of the cleaning device.

[0068] Optionally, in the above embodiments, the interference amount of the dust lifting assembly 2 with the cleaning surface is 0.1mm-0.5mm.

[0069] According to the design requirements of the cleaning device, in some embodiments, the dust lifting assembly 2 is spaced apart from the cleaning surface when the cleaning device is placed on the cleaning surface (for example, the ground), that is, the dust lifting assembly 2 can always maintain a preset distance from the cleaning surface with the rotation of the cleaning roller brush. It means that the dust lifting assembly 2 can always be spaced apart from the cleaning surface, and the distance between the dust lifting assembly 2 and the cleaning surface is maintained at a preset distance.

[0070] In the above embodiment, the dust lifting assembly 2 is always spaced apart from the contact surface, which can reduce the noise generated when the cleaning device is working.

[0071] Optionally, in the above embodiment, the distance between the dust lifting assembly 2 and the cleaning surface is 0.2mm-0.3mm.

[0072] Please refer to Figure 2 In some embodiments, a plurality of tooth grooves 1322 are formed on the protruding portions 132 on the two half shells 13 and are spaced apart in the axial direction of the shell 1.

[0073] When the winding is wound on the cutting portion 11 of the cleaning roller brush in the above embodiment, the winding is accommodated in the tooth grooves 1322 on the protruding portions 132 on the two half shells 13, so that the winding is horizontally arranged at the aperture of the cutting groove 12. When the cutting assembly 3 moves relative to the cutting portion 11, the cutting assembly 3 can cut the winding horizontally arranged at the aperture of the cutting groove 12.

[0074] Please refer to Figure 3 and Figure 4 In some embodiments, the cutting assembly 3 further comprises a driving group 32 and a transmission group 33, the cutting knife 31 comprises a first moving knife 311 and a second moving knife 312, under the driving of the driving group 32, the transmission group 33 can drive the first moving knife 311 and the second moving knife 312 to move relative to the cutting portion 11 along the axial direction of the shell 1, and the moving directions of the first moving knife 311 and the second moving knife 312 are opposite.
