Description

Technical Field

[0001] This disclosure relates to a floor brush assembly and surface cleaning equipment. Background Technology

[0002] Surface cleaning equipment can include dry surface cleaning equipment and wet surface cleaning equipment. Typical examples of dry surface cleaning equipment can be cleaning tools such as vacuum cleaners, while typical examples of wet surface cleaning equipment can be cleaning tools such as floor scrubbers.

[0003] When using surface cleaning equipment, there are usually rotating rollers or brushes. The rollers or brushes agitate the dust on the surface to be cleaned, and then the dust is sucked into the treatment device through the suction port for dust-air separation. The dust and other solid waste are kept inside the surface cleaning equipment, and then the clean gas is discharged to the outside of the surface cleaning equipment.

[0004] The rotation of the cylindrical agitator causes the bristles to sweep across the carpet surface and agitate the carpet fibers, which, combined with vacuum suction, removes dirt from the carpet fibers. During the removal process, lint or other fibrous materials may become entangled around the brush or its attachments. This can degrade the performance of the surface cleaning equipment.

[0005] In existing technologies, when cleaning objects entangled on the agitator, the agitator of the floor brush assembly generally needs to be removed, cleaned, and then reinstalled into the surface cleaning equipment. This operation is time-consuming and labor-intensive. Summary of the Invention

Detailed Implementation

[0038] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the disclosure. Furthermore, it should be noted that, for ease of description, only the parts relevant to the present disclosure are shown in the accompanying drawings.

[0039] It should be noted that, where there is no conflict, the embodiments and features described in this disclosure can be combined with each other. The technical solutions of this disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0040] Unless otherwise stated, the exemplary implementations / embodiments shown are to be understood as providing exemplary features of various details that provide ways in which the technical concepts of this disclosure can be implemented in practice. Therefore, unless otherwise stated, the features of various implementations / embodiments may be additionally combined, separated, interchanged and / or rearranged without departing from the technical concepts of this disclosure.

[0041] The use of crosshairs and / or shading in the accompanying drawings is generally used to clarify the boundaries between adjacent components. Thus, unless otherwise stated, the presence or absence of crosshairs or shading does not convey or indicate any preference or requirement for the specific material, material properties, dimensions, proportions, commonalities between the illustrated components, or any other characteristics, properties, etc., of the components. Furthermore, in the accompanying drawings, the dimensions and relative dimensions of components may be exaggerated for clarity and / or descriptive purposes. When exemplary embodiments can be implemented differently, a specific process sequence may be performed in a different order than that described. For example, two consecutively described processes may be performed substantially simultaneously or in the reverse order of their description. Furthermore, the same reference numerals denote the same components.

[0042] When a component is referred to as being "on" or "above" another component, "connected to," or "joined to" another component, the component may be directly on, directly connected to, or directly joined to the other component, or there may be intermediate components. However, when a component is referred to as being "directly on" another component, "directly connected to," or "directly joined to" another component, there are no intermediate components. Therefore, the term "connection" can refer to a physical connection, an electrical connection, etc., and may or may not have intermediate components.

[0043] For descriptive purposes, this disclosure may use spatial relative terms such as “below,” “under,” “below,” “down,” “above,” “above,” “higher,” and “side (e.g., in a “sidewall”)” to describe the relationship between one component and another component as shown in the accompanying drawings. In addition to the orientations depicted in the drawings, the spatial relative terms are also intended to encompass different orientations of the device during use, operation, and / or manufacture. For example, if the device in the drawings is flipped, a component described as “below” or “under” another component or feature would subsequently be positioned “above” said other component or feature. Thus, the exemplary term “below” can encompass both “above” and “below” orientations. Furthermore, the device may be otherwise positioned (e.g., rotated 90 degrees or in other orientations), thus interpreting the spatial relative descriptive terms used herein accordingly.

[0044] The terminology used herein is for the purpose of describing particular embodiments and is not intended to be limiting. As used herein, unless the context clearly indicates otherwise, the singular forms “a” and “the” are intended to include the plural forms as well. Furthermore, when the terms “comprising” and / or “including” and variations thereof are used in this specification, it indicates the presence of the stated features, integrals, steps, operations, parts, components, and / or groups thereof, but does not exclude the presence or addition of one or more other features, integrals, steps, operations, parts, components, and / or groups thereof. It should also be noted that, as used herein, the terms “substantially,” “about,” and other similar terms are used as approximate terms rather than as terms of degree, thus explaining the inherent biases in measurements, calculated values, and / or provided values ​​that would be recognized by one of ordinary skill in the art.

[0045] Figure 1 and Figure 2 This is a schematic diagram of the structure of a floor brush assembly of a surface cleaning apparatus according to one embodiment of the present disclosure. Figure 3 and Figure 4 This is a schematic diagram of the structure of a floor brush assembly according to another embodiment of the present disclosure.

[0046] like Figures 1 to 4 The floor brush assembly 10 shown can be applied to a surface cleaning device, and when the user operates the surface cleaning device, the surface to be cleaned can be cleaned by the floor brush assembly.

[0047] The floor brush assembly 10 may include a connecting part 100 to connect the floor brush assembly 10 to the frame part of the surface cleaning device. The connecting part 100 enables the housing part 200, the first stirring body 500 and the second stirring body 600 of the floor brush assembly 10 to always be kept on or near the surface to be cleaned, and the cleaning of the surface to be cleaned is achieved by the first stirring body 500 and the second stirring body 600.

[0048] In one implementation, the connecting part 100 can be formed as a snap-fit ​​structure, which facilitates the user to install the floor brush assembly 10 onto the frame part of the surface cleaning device and to remove it from the frame part of the surface cleaning device; at this time, the frame part can also install different floor brush assemblies 10 and achieve different cleaning methods.

[0049] In a preferred embodiment, the connecting part 100 is further provided with an electrical connection terminal 110, so that when the connecting part 100 is connected to the frame part of the surface cleaning device, the electrical connection terminal 110 can be connected to the battery of the frame part to supply power to the drive device 160 of the floor brush assembly 10.

[0050] The floor brush assembly 10 may further include a housing portion 200, which is connected to the connecting portion 100 via a connector 120. In a preferred embodiment, the connector 120 may be a universal joint, thereby enabling the frame portion to tilt in multiple directions relative to the housing portion 200.

[0051] In one embodiment, a roller 130 is rotatably provided on the housing 200, so that when the floor brush assembly 10 is performing a cleaning operation, the roller 130 rotates on the surface to be cleaned, thereby enabling the floor brush assembly 10 to move.

[0052] See again Figures 1 to 4 The floor brush assembly 10 may further include a first cover 300, which is disposed on the housing portion 200. In one embodiment, the first cover 300 is detachably disposed on the housing portion 200 and forms an internal space between it and the housing portion 200, and some components of the floor brush assembly 10, such as the drive device 160, may be disposed within the internal space.

[0053] Therefore, when the first cover 300 is disassembled, the first agitator 500 forms a passage from the front of the floor brush assembly 10 to the outside, which makes it easy to clean the first agitator 500. After cleaning the first agitator 500, the first cover 300 can be reinstalled into the housing 200. This greatly facilitates the cleaning of the first agitator 500 by the customer.

[0054] In a preferred embodiment, the second agitator 600 is a bristle brush. When a bristle brush is in use, it is easy for hair and other objects to get tangled, requiring frequent cleaning and maintenance. In this disclosure, the second cover 620 at least partially covers the second agitator 600, and the second cover 620 and the housing portion 200 are integrally formed. In this case, the second agitator 600 can be configured to be detached from the floor brush assembly in a lateral pull-out manner relative to the second cover 620.

[0055] In actual use, the user first removes the second agitator 600 from the floor brush assembly, and then cleans the second agitator 600 manually or automatically, such as removing hair or other objects tangled on the second agitator 600, and then installs the second agitator 600 horizontally onto the housing 200 of the floor brush assembly.

[0056] Figure 5 This is a schematic diagram of the structure of a floor brush assembly according to yet another embodiment of the present disclosure. Figure 6 This is a partial structural schematic diagram of the floor brush assembly of a surface cleaning apparatus according to one embodiment of the present disclosure.

[0057] like Figures 1 to 6 As shown, the housing portion 200 includes a receiving space 210 and a suction port 220 communicating with the receiving space 210; in this disclosure, the receiving space 210 may also be referred to as a roller brush chamber, a brush roller chamber, or a brush roller chamber, etc.

[0058] The accommodating space 210 can accommodate components such as the first stirring body 500, and the suction inlet 220 can be connected to the suction pipe 140, thereby allowing a mixture of dust and gas, or a mixture of dust, used cleaning liquid and gas, to enter the suction pipe 140 through the suction inlet 220 and be sucked to the frame of the surface cleaning device via the suction pipe 140.

[0059] In a preferred embodiment, the first cover 300 and the housing portion 200 together form the aforementioned receiving space 210; in a more preferred embodiment, the first cover 300 and the housing portion 200 together form the aforementioned suction inlet 220.

[0060] like Figures 1 to 7 As shown, the floor brush assembly 10 of this disclosure also includes a first stirring body 500, which is disposed on the drive rod 410 and located in the receiving space 210. The drive rod 410 drives the first stirring body 500 to rotate.

[0061] The structure of the first stirring body 500 will be described in detail below with reference to the accompanying drawings.

[0062] Figure 9 This is a schematic diagram of the structure of a stirring component according to one embodiment of the present disclosure.

[0063] In one embodiment, such as Figure 6 As shown, the first stirring body 500 is suspended so that the first stirring body 500 has a fixed end and a free end, wherein the fixed end is the end connected to the drive rod 410, and the free end is the suspended end.

[0064] In one implementation, the outer contour of the first agitator 500 is conical or substantially conical, and at least a portion of the first agitator 500 is in contact with the surface to be cleaned. For example, at least a portion of the bristles of the bristle row 510 of the first agitator 500 is in contact with the surface to be cleaned to agitate dust on the surface and achieve cleaning.

[0065] Continue to refer to Figure 5 and Figure 6The first stirring body 500 of this disclosure is arranged laterally, for example, laterally arranged in the receiving space. When the surface cleaning device is in use, the user moves the floor brush assembly forward or backward. Thus, the forward / backward direction of the floor brush assembly is its longitudinal direction, and the laterally arranged direction is approximately perpendicular to the longitudinal direction. Those skilled in the art should understand that the laterally arranged first stirring body 500 does not mean that the rotation axis OX of the first stirring body 500 is perpendicular to the longitudinal direction; rather, the rotation axis OX can be at a preset angle to the longitudinal direction, and this preset angle can be within a certain range. Furthermore, the laterally arranged direction does not refer to the horizontal direction; it can be at a certain angle to the horizontal direction.

[0066] like Figure 6 As shown in this disclosure, there are two first stirring bodies 500, and the free ends of the two first stirring bodies 500 are arranged close to each other and have a preset distance; thereby forming a gap between the two free ends of the first stirring body 500.

[0067] More preferably, the gap between the two first stirring bodies 500 corresponds to the position of the suction inlet. For example, the gap is located near the suction inlet. Thus, the disturbed dust can be transported to the vicinity of the suction inlet by the spirally arranged protrusions 520, so that the disturbed dust can be easily sucked into the suction inlet, greatly improving the cleaning effect.

[0068] In this disclosure, such as Figure 5 As shown, the first stirring body 500 is positioned biased towards the suction inlet from the fixed end to the free end, thereby making it easier for dust on the surface to be cleaned, stirred by the first stirring body 500, to be sucked into the suction inlet.

[0069] In other words, by setting the first stirring body 500 in this way, the flow path between the second stirring body 600 and the first stirring body 500 is smoother, and the cleaning effect on the surface to be cleaned is better.

[0070] In a specific embodiment, such as Figure 5 As shown, the first stirring body 500 has a rotation axis OX, and the angle between the rotation axis OX and the front of the floor brush assembly (i.e., the direction of movement of the floor brush assembly when cleaning the surface to be cleaned) is between 83° and 87°; more preferably, the angle can be 85°. In other words, the first stirring body 500 is tilted backward at an angle of about 5°.

[0071] In one embodiment, the first stirring body 500 is driven by its respective driving device 160, that is, when there are two first stirring bodies 500, there are also two driving devices 160.

[0072] The first stirring body 500 has a main body 501 with an outer cylindrical surface. The diameters at both ends of the main body 501 are substantially equal, and the outer diameter of the bearing 400 is greater than or equal to the diameter of the main body 501.

[0073] In another embodiment, the first stirring body 500 has a main body portion 501 with a tapered outer surface, such that the main body portion 501 at the fixed end has a larger diameter than the main body portion 501 at the free end.

[0074] As another implementation, such as Figure 9 As shown, a spirally extending bristle row 510 is provided on the outer surface of the main body 501 of the first stirring body 500 in the direction from the fixed end to the free end, and the bristle row 510 extends outward from the outer surface of the main body 501 of the first stirring body 500 by a first radial distance. The first radial distance decreases sequentially from the fixed end to the free end of the first stirring body 500. When the first stirring body 500 rotates, the bristle row 510 can contact the surface to be cleaned to disturb the dust on the surface to be cleaned.

[0075] More preferably, a spirally extending protrusion 520 is provided on the outer surface of the main body 501 of the first stirring body 500 in the direction from the fixed end to the free end, and the bristle row 510 extends outward from the protrusion 520.

[0076] In this disclosure, the protrusion 520 extends outward from the outer surface of the main body portion 501 of the first stirring body 500 by a second radial distance, and the second radial distance decreases sequentially from the fixed end to the free end of the first stirring body 500.

[0077] In one specific implementation, the protrusion 520 includes a base 521 and a pair of ridges 522, the base 521 and the pair of ridges 522 being arranged radially outward from the outer surface of the main body 501 of the first stirring body 500, the bristle row 510 extending outward from the base 521 and disposed between the pair of ridges 522, the tip of the bristle row 510 extending outward from the pair of bases 521.

[0078] In one implementation, the base 521 has a third radial distance that decreases sequentially from the fixed end to the free end of the first stirring body 500, and the bristle row 510 has a constant fourth radial distance.

[0079] In another implementation, the base 521 has a constant third radial distance, and the bristle row 510 has a fourth radial distance, which decreases sequentially from the fixed end to the free end of the first stirring body 500.

[0080] In this disclosure, the floor brush assembly 10 further includes a support portion 150; in one embodiment, the support portion 150 can be fixed to the housing portion 200, or the support portion 150 can be fixed to a structure such as the first cover 300.

[0081] The support portion 150 is used to fix the drive device 160. In one embodiment, the drive device 160 can be a commonly used motor such as a DC motor or a stepper motor, and can be held by the support portion 150. Of course, the drive device 160 can also be fixed to the housing portion 200 and held by the housing portion 200. More preferably, the drive device 160 can be held by both the support portion 150 and the housing portion 200.

[0082] In a preferred embodiment, the support portion 150 can be formed separately from the housing portion 200. Of course, those skilled in the art should know that the support portion 150 can also be formed integrally with the housing portion 200.

[0083] like Figure 6 As shown, a driving synchronous pulley 170 is mounted on the output shaft of the drive device 160, and a driven synchronous pulley 180 is mounted on the drive rod 410. The driving synchronous pulley 170 and the driven synchronous pulley 180 are connected by a synchronous belt drive, thereby enabling the drive device 160 to drive the drive rod 410 to rotate. Of course, the synchronous belt drive mechanism can also be replaced by a chain drive mechanism or a gear drive mechanism, etc., which will not be described in detail here.

[0084] Figure 7 This is a cross-sectional structural schematic diagram of a floor brush assembly according to one embodiment of the present disclosure.

[0085] like Figure 7 As shown, the floor brush assembly 10 may further include a bearing 400. In one embodiment, the bearing 400 may be disposed on the housing portion 200, in which case a bearing seat may be formed on the housing portion 200 so that the bearing is disposed in the bearing seat of the housing portion 200.

[0086] In another embodiment, such as Figure 7 As shown, the support portion 150 has a bearing housing, and the bearing 400 is disposed in the bearing housing of the support portion 150, thereby indirectly disposing the bearing 400 in the housing portion 200.

[0087] More preferably, such as Figure 7As shown, the support portion 150 has a stepped portion 151, and the bearing 400 can be positioned by the stepped portion 151; correspondingly, the support portion 150 also has a hook portion 152, and the bearing 400 can also be positioned by the hook portion 152.

[0088] In a preferred embodiment, the number of bearings 400 is two, for example, two ball bearings. Of course, the two bearings 400 can also be configured as angular contact bearings mounted back-to-back or face-to-face.

[0089] The outer ring of one of the two bearings 400 is positioned by the stepped portion 151, and the outer ring of the other bearing 400 is positioned by the hook portion 152, thereby fixing the axial position of the two bearings 400.

[0090] like Figure 7 As shown, the floor brush assembly 10 of this disclosure also includes a drive rod 410, which is disposed on the bearing 400 and rotatably supported by the bearing 400. That is, the drive rod 410 can be fixed to the inner ring of the bearing 400. For example, the size of the drive rod 410 can be slightly larger than the inner diameter of the inner ring of the bearing 400, so that the drive rod 410 cannot move axially relative to the bearing 400 by means of interference fit.

[0091] Furthermore, due to the characteristics of the bearing 400, the drive rod 410 can rotate, and at this time, the drive device 160 can drive the drive rod 410 to rotate.

[0092] In this disclosure, one end of the drive rod 410 is located in the receiving space 210, and a first stirring body 500 is installed at that end; the other end of the drive rod 410 is located outside the receiving space 210, and a driven synchronous pulley 180 is installed at that end.

[0093] At this time, the bearing 400 is configured such that when the first stirring body 500 is mounted on the drive rod 410, the first stirring body 500 is rotatably held in the housing portion 200 when the outer peripheral surface of the bearing 400 (i.e. the outer peripheral surface of the outer ring of the bearing 400) is in contact with the housing portion 200; and the outer diameter of the bearing 400 is less than or equal to the maximum diameter of the outer peripheral surface of the first stirring body 500.

[0094] Therefore, the bearing 400 configuration can stably support the first stirring body 500, improve the operational stability of the floor brush assembly 10, and thus improve the cleaning effect on the surface to be cleaned.

[0095] In one embodiment, the outer diameter of the bearing 400 is less than or equal to the outer diameter of the first stirring body 500 fixed to one end of the drive rod 410.

[0096] In another embodiment, the outer diameter of the bearing 400 is less than or equal to the minimum outer diameter of the outer circumferential surface of the first stirring body 500. For example, the outer diameter of the bearing 400 is less than or equal to the outer diameter of the end of the first stirring body 500 away from the drive rod 410.

[0097] In this disclosure, such as Figure 7 As shown, the drive rod 410 includes a drive shaft 411 and a drive member 412. One end of the drive shaft 411 passes through the bearing 400 and is at least partially located within the receiving space 210. The drive member 412 is mounted on the same end of the drive shaft 411 and is located within the receiving space 210. The drive shaft 411 is fixed with the aforementioned driven synchronous pulley 180, and the drive member 412 is drively connected to the first stirring body.

[0098] like Figure 1 As shown, the first cover 300 includes a pair of conical inner walls, and the outer surface of the first stirring body 500 is in contact with the conical inner walls.

[0099] More preferably, the pair of conical inner walls includes a joint, which is the location where the two conical inner walls intersect, and the location of the joint corresponds to the gap between the free ends of the pair of first stirring bodies 500. Furthermore, the location of the joint corresponds to the location of the suction inlet 220.

[0100] More preferably, the floor brush assembly may further include a second stirring body 600, which is rotatably disposed in the housing portion 200 and located in front of the first stirring body 500. A vacuum flow channel is formed between the first stirring body 500 and the second stirring body 600. Therefore, the arrangement of the first stirring body 500 and the second stirring body 600 allows for a more thorough cleaning of the surface to be cleaned. Specifically, when the surface cleaning device cleans the surface to be cleaned, as the floor brush assembly moves forward, the second stirring body 600 first cleans the surface, agitating the dust on the surface; then the first stirring body 500 cleans the surface again, agitating the dust, thereby making the cleaned surface even cleaner.

[0101] In this disclosure, the second stirring body 600 can be driven to rotate. For example, the second stirring body 600 can be formed in the form of a cylindrical roller brush. A driving device, such as a motor, can be disposed inside the second stirring body 600, thereby enabling the second stirring body 600 to rotate. Correspondingly, both ends of the second stirring body 600 are rotatably supported on the housing portion 200 by bearings. In a preferred embodiment, the second stirring body 600 can also be arranged laterally or horizontally.

[0102] Figure 10 This is a bottom view of a floor brush assembly according to one embodiment of the present disclosure.

[0103] In a specific example, such as Figure 10 As shown, the floor brush assembly further includes a cleaning unit 640, which is disposed in the housing portion 200 and is used to clean the outer surface of the second stirring body 600.

[0104] Moreover, such as Figure 7 As shown, the floor brush assembly further includes a cleaning component 800, which is disposed between the first stirring body 500 and the second stirring body 600 and interferes with the first stirring body 500 to remove debris from the first stirring body 500 and transfer the debris to the second stirring body 600 and / or the suction inlet 220 through a part of the vacuum channel; wherein, the cleaning component 800 includes an interference portion that interferes with the first stirring body 500.

[0105] More preferably, the interference portion of the cleaning component 800 can be configured to exist in the direction from the fixed end to the free end of the first stirring body 500, thereby increasing the interference position / interference area between the cleaning component 800 and the first stirring body 500.

[0106] In one specific embodiment, the cleaning component 800 is configured to extend from the housing portion 200 in a gradually widening manner along the direction from the fixed end to the free end of the first stirring body 500, thereby enabling the cleaning component 800 to interfere with the outer surface of the main body portion 501 of the first stirring body 500, which is formed in a conical shape, thereby improving the efficiency of the cleaning component 800 in cleaning the first stirring body 500.

[0107] In this disclosure, the cleaning component 800 includes components such as a cleaning base 810 and a scraper 820.

[0108] The cleaning base 810 extends from the housing portion 200; of course, those skilled in the art should know that the cleaning base 810 can also be formed independently and fixed to the housing portion 200; in a preferred embodiment, the cleaning base 810 can exist through the housing portion 200, of course, the cleaning base 810 may not penetrate the housing portion 200.

[0109] The scraper 820 is formed on the side of the cleaning base 810, and the aforementioned interference portion is formed by the scraper 820; that is, when the cleaning base 810 is in the working state, as the first stirring body 500 rotates, the first stirring body 500 can contact the upper edge or the lower edge of the scraper 820, thereby removing dust and other solid waste from the surface of the first stirring body 500. In a preferred embodiment, the scraper 820 only contacts the bristle row 510 of the first stirring body 500, thereby cleaning the dirt on the bristle row 510.

[0110] In this disclosure, such as Figure 7 As shown, the cleaning base 810 is configured to extend from the housing portion 200 in a gradually widening manner along the direction from the fixed end to the free end of the second stirring body, so that the scraper 820 interferes with the first stirring body 500 in the direction from the fixed end to the free end of the first stirring body 500.

[0111] When the number of first stirring bodies 500 is different, the structure of the cleaning component 800 is also different accordingly. For example, when there is only one first stirring body 500, the cleaning base 810 can vary with the outer surface of the main body 501 of the first stirring body 500.

[0112] On the other hand, when there are two first stirring bodies 500, the scraper 820 may include a first inclined portion 821 and a second inclined portion 822, the first inclined portion 821 and the second inclined portion 822 are formed into a V-shaped structure, and the corner of the V-shaped structure faces the suction inlet 220, thereby enabling the scraper 820 to clean the two first stirring bodies 500 at the same time.

[0113] The scraper 820 is configured to extend from the cleaning base 810 in a gradually widening manner along the direction from the fixed end to the free end of the first stirring body 500, such that the scraper 820 interferes with the first stirring body 500 in the direction from the fixed end to the free end of the first stirring body 500.

[0114] In this disclosure, the main body 501 includes a conical portion and / or a cylindrical portion. As different implementations, from the fixed end to the free end of the first stirring body 500: the main body 501 sequentially includes a cylindrical portion, a conical portion, and a cylindrical portion; or the main body 501 sequentially includes a cylindrical portion and a conical portion; or the main body 501 sequentially includes a conical portion and a cylindrical portion.

[0115] Figure 11 This is a schematic diagram of the structure of a cleaning unit according to one embodiment of the present disclosure. Figure 12 yes Figure 11 Enlarged schematic diagram of part A.

[0116] In a specific example, such as Figure 11 and Figure 12 As shown, the cleaning unit 640 includes cleaning protrusions 641 spaced apart along the length of the second mixing body 600. The cleaning protrusions 641 extend partially into the second mixing body 600 and have a lower edge that is aligned with or located below the axis of the second mixing body 600.

[0117] Figure 13 This is a schematic diagram of the structure of a cleaning unit according to one embodiment of the present disclosure.

[0118] like Figure 13 As shown, the lower edge of the cleaning protrusion 641 is inclined so that the cleaning protrusion as a whole is lower than the horizontal plane where the axis of the second stirring body 600 is located.

[0119] More preferably, the cleaning protrusion 641 further includes an upper edge, the front end of the upper edge of the cleaning protrusion 641 is inserted into the second stirring body 600, so that the part of the cleaning protrusion 641 inserted into the second stirring body 600 is formed into a pointed shape. At this time, the hair and other objects cleaned by the cleaning protrusion 641 can be held at the upper edge of the cleaning protrusion 641.

[0120] In this disclosure, the upper edge of the cleaning protrusion 641 is inclined downward in the direction from front to back, so that the cleaning protrusion 641 can hold more garbage and prolong the time between the two disassemblies of the second mixing body 600.

[0121] In a preferred embodiment, the axis of the second stirring body 600 is horizontally arranged laterally.

[0122] In this disclosure, the floor brush assembly may further include a latch (not shown in the figure) configured to engage with the first cover 300 to removably connect the first cover 300 to the housing portion 200; the structure of the latch may adopt conventional implementations in the art, and will not be described in detail here.
