Description

Technical Field

[0001] The present disclosure relates to cleaning electrical equipment, and more particularly, to cleaning components and electrical equipment. Background Art

[0002] Floor cleaning equipment is widely used. Floor cleaning equipment usually includes one or more roller brushes that rotate along a horizontal axis as a cleaning tool. When the floor cleaning equipment performs a cleaning operation, the roller brush contacts the floor to be cleaned and can clean the floor with the help of a cleaning liquid. The cleaning liquid is applied to the floor or the roller brush during the cleaning process. Subsequently, the applied cleaning liquid, together with the cleaned dirt, is transferred to a dirty liquid storage container under the action of the roller brush. Due to the need to contact dirt and dirty liquid, the self-cleaning function of the roller brush during use is an important function. It can improve the cleaning effect of the cleaning equipment to a certain extent by keeping the roller brush itself clean.

[0003] In the patent application with application number 202322166481.0, a cleaning assembly with a self-cleaning function and a cleaning assembly with such a cleaning assembly are introduced. The cleaning assembly with a self-cleaning function includes a cylindrical rotating portion, an arcuate baffle and an abutment portion. The cylindrical rotating portion is used to clean the support surface and has a cylindrical surface. The arcuate baffle faces the cylindrical surface of the cylindrical rotating portion and is positioned above the cylindrical rotating portion at a distance from the cylindrical surface. The abutment portion has a first end and a second end, the first end of the abutment portion is coupled to the arcuate baffle, and the second end of the abutment portion abuts against the cylindrical surface of the cylindrical rotating portion, wherein a portion of the cylindrical surface of the cylindrical rotating portion, the arcuate baffle and the abutment portion together form a channel. The channel is configured to utilize flowing liquid to clean the interior of the channel in an operating state. Thus, the cleaning assembly advantageously utilizes the liquid flowing in the channel from the roller, the arcuate baffle and the abutment portion inside the main flushing channel. Utility Model Content

[0004] The present disclosure aims to provide a solution for a cleaning assembly comprising a water storage chamber formed by a scraper having a certain length and an arc-shaped water blocking member.

[0005] One aspect of the present disclosure provides a cleaning assembly. The cleaning assembly includes: a rotating drum configured to rotate in a first direction around a rotation axis to clean a surface to be cleaned, the rotating drum including a cleaning portion extending circumferentially around the rotation axis, and the cleaning portion including a cleaning position for contacting the surface to be cleaned and an opposing position radially opposite to the cleaning position; an arcuate water-blocking member extending from a first water-blocking member end to a second water-blocking member end in a first direction around the rotation axis and spaced from the cleaning portion; and a scraper including: a first scraper end connected to the arcuate water-blocking member; a second scraper end abutting a position of the cleaning portion downstream of the opposing position in the first direction; and a plate body extending from a first end to a second end, wherein a first distance from the first end to a cross-section of the rotating drum at the cleaning position is not greater than a second distance from the second end to the cross-section.

[0006] According to an embodiment of the present disclosure, when the drum rotates in a first direction, the cleaning portion located on the outside of the drum contacts the surface to be cleaned and absorbs dirty liquid and dirt on the surface to be cleaned. A water storage chamber is formed by the plate body of the scraper and the arc-shaped water-blocking member. The liquid collected in the water storage chamber can flow toward the scraper as the cylindrical rotating portion rotates, thereby flushing the water storage chamber and achieving a better self-cleaning effect. Since the plate body has a certain length, dirty liquid will hardly accumulate on the cleaning portion, thereby improving the cleanliness of the cleaning portion and reducing and improving the cleaning efficiency.

[0007] In some embodiments, the arcuate water-blocking member further includes an opening adjacent to the end of the first scraper, the opening extending from a side of the arcuate water-blocking member facing the rotating drum to a side facing away from the rotating drum. In such an embodiment, the opening can guide the flow of the dirty liquid to form a dirty liquid stream and discharge the dirty liquid in a timely manner.

[0008] In some embodiments, the opening is located in the middle of the scraper in the second direction parallel to the rotation axis. In such an embodiment, the opening located in the middle can guide the dirty liquid on both sides, thereby improving the guiding efficiency of the dirty liquid flow.

[0009] In some embodiments, the first scraper end is connected to the second water blocking member end. In such an embodiment, the size of the arc-shaped water blocking member can be reduced, making the cleaning assembly more compact.

[0010] In some embodiments, the end portion of the second water-blocking member includes an end surface facing the cut surface, the end portion of the first scraper includes a surface facing the arc-shaped water-blocking member, and the end portion of the second water-blocking member is connected to the end surface via a threaded connection, such that the end surface abuts the surface. In such an embodiment, the threaded connection can achieve a liquid-tight connection, preventing loss of contaminated liquid.

[0011] In some embodiments, the scraper and the arc-shaped water-blocking member are integrally formed. In such an embodiment, by integrally forming, sealing between the scraper and the arc-shaped water-blocking member can be achieved, and assembly is simplified.

[0012] In some embodiments, the scraper extends in a U-shape in a third direction parallel to the rotation axis, with the bottom of the U protruding obliquely toward the tangential surface. In such an embodiment, when liquid flows onto the scraper, it is quickly guided to the opening under the action of gravity, increasing the flow rate and the fluid throughput, thereby achieving greater flushing power.

[0013] In some embodiments, the end of the second water blocking member corresponds to the U-shape in the third direction, and the inner front wall of the arc-shaped water blocking member adjacent to the end of the second water blocking member corresponds to the end of the second water blocking member. In such an embodiment, when liquid is scraped onto the scraper, the liquid can flow toward the opening under the guidance of the inner front wall.

[0014] In some embodiments, the cleaning portion includes an abutment position where the U-shaped end abuts, and the angle between a first radial plane passing through the rotation axis, where the abutment position is located, and a second radial plane passing through the rotation axis, where the opposing position is located, is in a range of 5° to 25°. In such an embodiment, positioning the end of the scraper within this angle range can prevent excessive dirty liquid from being stored on the scraper.

[0015] In certain embodiments, the cleaning portion includes a bristle roller brush, and the scraper is in interference contact with the bristle roller brush. In such embodiments, the scraper can improve the scraping effect of the scraper on dirt by interference contact.

[0016] In certain embodiments, the distance between the scraper and the cleaning portion is between 6 and 9 millimeters. In such an embodiment, by arranging the scraper within this range, the demand for flushing force can be met while the water storage chamber can be made too large.

[0017] In some embodiments, the arcuate water-blocking member includes at least a first component and a second component. The first component includes a first water-blocking member end portion and is connected to the rotating drum, and the second component includes a second water-blocking member end portion and is detachably connected to the first component. In such an embodiment, by making the scraper and the arcuate water-blocking member detachable, it is possible to facilitate maintenance by the user. In some embodiments, the scraper and the second component are integrally formed. In such an embodiment, the scraper and the second component become replacement parts that can be easily disassembled, cleaned, and maintained, while the first component serves as a fixed component to connect the drum to form the drum cavity.

[0018] A second aspect of the present disclosure provides an electrical device comprising: a main body; a cleaning assembly according to the first aspect of the present disclosure, fixed in the main body; and a dirty liquid storage member disposed in the main body and configured to receive dirty liquid from the cleaning assembly.

[0019] According to one or more embodiments, the electrical device includes any one of the following: a sweeping robot, a mopping robot, a floor scrubber, a sweeping and mopping robot, or a handheld electric mop.

[0020] The various aspects and advantages of the cleaning assembly described above are also applicable to the electrical device according to the present disclosure, and therefore will not be elaborated herein. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Unless otherwise indicated, corresponding numbers and symbols in different figures generally refer to corresponding regions. The accompanying drawings are drawn to clearly illustrate the relevant aspects of the embodiments and are not necessarily drawn to scale. The edges of features drawn in the drawings do not necessarily represent the ends of the features.

[0030] In the following description, various specific details are shown to provide a thorough understanding of various examples of embodiments according to the description. Embodiments may be obtained without one or more of the specific details, or with other methods, components, materials, etc. In other cases, well-known structures, materials, or operations are not shown or described in detail so as not to obscure aspects of the embodiments.

[0031] References to "one embodiment" or "an implementation" in the framework of this specification are intended to indicate that a particular configuration, structure, or characteristic described with respect to that embodiment is included in at least one embodiment. Therefore, phrases such as "in an embodiment," "in one embodiment," and the like that may appear in various places throughout this specification do not necessarily refer to the same embodiment. Furthermore, particular configurations, structures, or characteristics may be combined in any appropriate manner in one or more embodiments.

[0032] Unless otherwise stated, when two elements are referred to as being connected together, this means there is no direct connection without any intermediate elements, and when two elements are referred to as being coupled together, this means the two elements may be connected or they may be coupled via one or more other elements.

[0033] The titles / reference numerals used herein are provided for ease of reading only and do not limit the scope of protection or the scope of the embodiments. Identical or similar elements are identified by the same reference numerals.

[0034] As discussed above, in the related art, a portion of the cylindrical surface of the cylindrical rotating portion of the cleaning assembly, the arc-shaped baffle, and the abutment portion together form a channel, and during the cleaning process, a dynamic water flow is formed in the channel to flush the multiple components in the channel. In such a scheme, since a portion of the channel is formed by the cylindrical surface of the cylindrical rotating portion, part of the cylindrical surface remains in the dirty liquid during the cleaning process. During the self-cleaning process, since no external dirt enters the channel, the self-cleaning function of this type of cleaning assembly in the related art can meet the requirements. However, during the cleaning operation, due to the continuous addition of dirty liquid and dirt, the cylindrical portion in the channel cannot be fully cleaned, resulting in the possibility that the cleanliness of the cylindrical surface is not high, thereby reducing the overall cleaning efficiency.

[0035] In view of this, the present disclosure provides a cleaning assembly including a scraper of a certain length. In this cleaning assembly, an arc-shaped water-blocking member and the scraper form a water storage chamber that can temporarily gather and guide flowing liquid (such as clean water or cleaning liquid) to flush the various components in the water storage chamber. The scraper is used instead of a rotating drum to form the water storage chamber, which reduces the contact time between the cleaning part and the dirty liquid, improves the cleaning degree of the cleaning part, and thus improves the overall cleaning efficiency.

[0036] Figure 1A A partial cross-sectional view of an exemplary electrical device 10 according to an embodiment of the present disclosure is shown. As shown in FIG1 , the electrical device 10 is capable of traveling along a second direction D2 on a surface 20 to be cleaned, such as a floor, to clean the surface 20. The electrical device 10 includes a main body 11, a cleaning assembly 100 fixed to the main body 11 for performing a primary cleaning operation, and a dirty liquid storage member 12 for receiving dirty liquid from the cleaning assembly 100.

[0037] The cleaning assembly 100 includes a drum 110. The drum 110 can rotate along a first direction D1 around a rotation axis R to clean the surface 20 to be cleaned. Figure 1A As shown, when the cleaning assembly 100 is assembled in the electrical device 10 and placed on the surface to be cleaned 20 , the drum 110 contacts the surface to be cleaned 20 at the cleaning position 113 of the cleaning portion 111 .

[0038] The cleaning assembly 100 also includes an arcuate water-blocking member 120. A water-blocking member body 123 of the arcuate water-blocking member 120 extends from a first water-blocking member end 121 to a second water-blocking member end 122 along a first direction D1 about a rotation axis R and is spaced apart from the cleaning portion 111. A portion or all of the arcuate water-blocking member 120 defines a space within which the drum 110 is mounted and rotated.

[0039] Furthermore, the cleaning assembly 100 further includes a scraper 130 for receiving dirty liquid and dirt from the cleaning portion 111. The scraper 130 includes a first scraper end 131 connected to the arcuate water blocking member 120, and a second scraper end 132 abutting against the cleaning portion 111. The cleaning portion 111 further includes an opposing position 114 radially opposed to the cleaning position 113. The first scraper end 131 is located downstream of the opposing position 114 in the first direction D1.

[0040] When the electrical device 10 having the cleaning assembly 100 travels in the second direction D2, the cleaning portion 111 of the rotating drum 110 rotates in the first direction D1, which is opposite to the second direction D2, to clean the surface 20 to be cleaned. After contacting the surface 20 to be cleaned, the cleaning portion 111 absorbs dirt and / or dirty liquid from the surface 20 to be cleaned. As the cleaning portion 111 continues to rotate, the dirt and / or dirty liquid absorbed by the cleaning portion 111 enters the space formed by the curved water-blocking member 120. Under the action of centrifugal force, some of the dirty liquid absorbed by the cleaning portion 111 is thrown onto the curved water-blocking member 120. The dirt and / or dirty liquid remaining on the cleaning portion 111 then reaches the scraper 130 and, after entering and exiting the second scraper end 132, is scraped off and remains on the scraper 130. With the dirt and / or dirty liquid scraped off, the cleaning portion 111 continues to rotate and performs the cleaning operation again at the cleaning position 113.

[0041] It should be understood that although Figure 1A In the embodiment shown, the electrical device 10 is a sweeping robot. The electrical device 10 according to the present disclosure may also be a mopping robot, a floor scrubber, a sweeping and mopping robot, a handheld electric mop, or any device having a cylindrical rotating portion for cleaning a surface to be cleaned.

[0042] The following will refer to Figure 1B The structure of the cleaning assembly 100 will be described in detail. Figure 1B 1 shows a cross-sectional view of an example cleaning assembly 100 according to an embodiment of the present disclosure. Figure 1B As shown, the rotating drum 110 of the cleaning assembly 100 also includes a cylindrical roller 112 located in the middle. The cleaning portion 111 is circumferentially arranged on the outside of the roller 112 around the rotation axis R and can rotate with the roller 112. The preferred cleaning portion 111 can also be removed from the roller 112 for maintenance or replacement. For example, the cleaning portion 111 can be a flexible material with bristles. It should be understood that although the cleaning portion 111 is always rotating during the cleaning operation, it is always in contact with the surface 20 to be cleaned at the cleaning position 113. At this time, the cleaning position 113 is the lowest point of the rotating drum 110. The cleaning portion 111 includes a virtual section A at the cleaning position 113. Section A is perpendicular to the line connecting the rotation axis R and the cleaning position 113.

[0043] The arc-shaped water-blocking member 120 also includes an arc-shaped main body 123. The arc-shaped main body 123 extends around the rotation axis R from a position adjacent to the section A to form a cavity for accommodating the drum 110. The arc-shaped main body 123 includes an inner front wall 125. The inner front wall 125 is provided on the side of the scraper 130 facing the inner side of the arc-shaped water-blocking member 120. As shown in the figure, the inner front wall 125 extends from the scraper 130 in a direction away from the section A on the inner side of the arc-shaped main body 123. In some embodiments, the inner front wall 125 can be perpendicular to the section A or inclined to the section A. Figure 1B In the embodiment shown, the inner front wall 125 is inclined relative to the tangent plane A.

[0044] The first scraper end 131 of the scraper 130 is adjacent to the second water blocking member end 122 of the arc-shaped water blocking member 120. It should be understood that the arc-shaped water blocking member 120 can also continue to extend along the first direction D1 at the position connected to the first scraper end 131, so that the first scraper end 131 is connected to the arc-shaped water blocking member 120 between the first water blocking member end 121 and the second water blocking member end 122. Figure 1B As shown, a first distance H1 between the first scraper end 131 and the cut surface A is less than or equal to a second distance H2 between the second scraper end 132 and the cut surface A.

[0045] In some embodiments, the scraper 130 varies in a direction perpendicular to the cut plane A. In such an embodiment, a first distance H1 between the first scraper end 131 and the cut plane A may be a first average distance between a plurality of positions of the first scraper end 131 of the scraper 130 and the cut plane A, and a second distance H2 between the second scraper end 132 and the cut plane A may be a second average distance between a corresponding plurality of positions of the second scraper end 132 of the scraper 130 and the cut plane A.

[0046] like Figure 1B As shown, the portion of the scraper 130 connected to the second water-blocking member end 122 is a first scraper end 131. Here, the second water-blocking member end 122 includes an end face facing the section A. A groove extending in a direction perpendicular to the section A is provided at the end face. The first scraper end 131 is fixed in the groove. In some embodiments, the first scraper end 131 can be connected to the second water-blocking member end 122 in a liquid-tight manner. The plate body 133 of the scraper 130 is a second scraper end 132 extending from the inner side wall 125 to abut against the cleaning portion 111.

[0047] The scraper 130 has a certain width. During the cleaning operation, the cleaning portion 111, when in contact with the surface to be cleaned at the cleaning position 113, absorbs dirty liquid from the surface to be cleaned. Subsequently, the cleaning portion 111 rotates with the roller 112. When the cleaning portion 111 contacts the scraper 130, the dirty liquid absorbed by the cleaning portion 111 is transferred to the plate body 133 via the scraper 130, entering the water storage chamber formed by the plate body 133, the inner front wall 125 of the curved water-blocking member 120, and the top wall portion of the curved water-blocking member 120 connected to the inner front wall. The dirty liquid accumulates in the water storage chamber and forms a certain liquid flow, which flushes various parts of the water storage chamber and the portion of the cleaning portion 111 adjacent to the second scraper end 132.

[0048] like Figure 1B As shown, the arcuate water-blocking member 120 further includes an opening 124 adjacent to the first scraper end 131 for directing contaminated liquid from the water storage chamber. Opening 124 extends from the side of the arcuate water-blocking member 120 facing the rotating drum 110 to the side facing away from the rotating drum 110, thereby connecting the water storage chamber with the exterior of the cleaning assembly 100. In some embodiments, opening 124 can be located in the middle of the scraper 130 in a third direction D3 parallel to the rotation axis R.

[0049] exist Figure 1BIn the illustrated embodiment, the distance between the scraper 130 and the cut surface A varies depending on the location of the opening 124. In some embodiments where the opening 124 is located in the middle, the distance between the scraper 130 and the cut surface A decreases in a third direction D3 from the end face of the drum 110 to the middle opening 124. From the opening 124 to the other end face of the drum 110, the distance between the scraper 130 and the cut surface A increases in the third direction D3. Thus, the distance between the scraper 130 and the cut surface A forms a V-shape or a U-shape in the third direction D3, with the tip of the V or the bottom of the U located in the middle of the opening 124. This allows the waste liquid in the water storage chamber to be guided to the opening 124 by gravity. In such embodiments, the cleaning portion 111 includes an abutment position 115 against which the end of the U abuts. An included angle between a first radial plane passing through the rotation axis R and where the abutting position 115 is located and a second radial plane passing through the rotation axis R and where the opposing position 114 is located is in a range of 5° to 25°.

[0050] exist Figure 1B In the illustrated embodiment, the distance between the inner front wall 125 and a plane perpendicular to the front face A also varies. The inner front wall 125 extends in a U-shape in a third direction D3 parallel to the rotation axis R, with the bottom of the U extending away from the drum 110. Thus, the distance between the inner front wall 125 and the plane perpendicular to the front face A forms a V-shape or a U-shape in the third direction D3, with the tip of the V-shape or the bottom of the U-shape located in the middle of the opening 124, thereby directing waste liquid from the water storage chamber to the opening 124.

[0051] Figure 2A 1 shows a schematic diagram of a portion 200A of an electrical device including an example cleaning assembly according to an embodiment of the present disclosure. Figure 2A As shown, part 200A includes a cleaning assembly 100 according to an embodiment of the present disclosure and a dirty liquid storage member 12 corresponding to the cleaning assembly 100. The dirty liquid storage member 12 includes a notch 202. The notch 202 is aligned with the opening 124 of the cleaning assembly 100, so that dirty liquid from the water storage chamber of the cleaning assembly 100 guided by the opening 124 can enter the dirty liquid storage member 12 through the notch 202.

[0052] exist Figure 2A, the curved water-blocking member 120 of the cleaning assembly 100 is primarily shown. The curved water-blocking member 120 includes a first water-blocking member end 121 adjacent to the bottom of the electrical device and thus adjacent to the surface to be cleaned. The curved water-blocking member 120 also includes an arc-shaped water-blocking member body 123 extending approximately 180° around the rotation axis R. The curved water-blocking member 120 also includes a second water-blocking member end 122 adjacent to the dirty liquid storage member 12. In addition, the curved water-blocking member 120 also includes end caps 128 at both ends in the third direction D3. The end caps 128 are used to form end-side sealing portions to seal the water storage chamber. The end caps 128 can serve as supports for the rotating drum 110. In some embodiments, a rotating shaft can be provided on one of the end caps 128. The rotating drum 110 can be rotatably supported on the rotating shaft.

[0053] Figure 2B A schematic diagram of a portion 200B of an electrical device including an example cleaning assembly according to an embodiment of the present disclosure is shown. The portion 200B corresponds to, for example, Figure 2A The portion 200A shown in FIG. 200B is different from the portion 200A in that the portion 200B does not include a portion of the top of the arc-shaped water blocking member 120. It can be understood that the portion of the top is omitted here to more clearly illustrate the scraper 130 in contact with the cleaning portion 111. Figure 2B As shown, the scraper 130 is arc-shaped and closely adheres to the cleaning portion 111. The opening 124 is located in the middle of the drum 110 in the third direction D3. The distance between the scraper 130 and the tangent plane A forms a U-shape in the third direction D3, and the bottom of the U-shape is located in the middle of the opening 124. Therefore, the dirty liquid in the water storage chamber is guided to the opening 124 under the action of gravity.

[0054] In some embodiments, the arcuate water-blocking member 120 may include multiple parts. A first part of the multiple parts may include a first water-blocking member end 121, and a second part of the multiple parts may include a second water-blocking member end 122. The first part and the second part are detachably connected. In such an embodiment, the second part may be detachably connected to the scraper 130, or may be integrally formed with the scraper 130, while the first part is fixed to the electrical device. As a result, the scraper 130 and the second part become replacement parts that can be easily disassembled, cleaned, and maintained, while the first part is connected to the drum as a fixed part and forms a space for the drum.

[0055] Figure 2C FIG. 2 shows a schematic diagram of a portion 200C of an electrical device including a scraper 130 and a drum 110 according to an embodiment of the present disclosure. Figure 2CAs shown, part 200C includes a rotating drum 110 and a scraper 130 in contact with the rotating drum 110. The rotating drum 110 includes a first end E1 and a second end E2 in the third direction D3. One end of the scraper 130 abuts against an abutment position 115-1 of the cleaning portion 111 of the rotating drum 110 at the first end E1. Conversely, the other end of the scraper 130 abuts against an abutment position 115-2 of the cleaning portion 111 of the rotating drum 110 at the second end E2. The scraper 130 is arranged in a U-shape in the third direction D3. The section of the scraper 130 at the bottom of the formed U-shape is lower than the sections of the scraper 130 at the two ends of the U-shape in a direction perpendicular to the cross-section A. As a result, the dirty liquid received by the sections at the adjacent end positions of the U-shape will converge toward the center under the action of gravity to achieve guidance of the dirty liquid.

[0056] In addition, in order to ensure the performance of the scraper 130 in receiving dirty liquid over the entire length of the third direction D3, the second scraper end 132 of the scraper 130 is in interference contact with the cleaning portion 111, that is, the second scraper end 132 extends into the gap between the bristles on the surface of the cleaning portion 111, or squeezes the bristles toward the drum 110 for a certain distance. In such an embodiment, each point on the edge where the second scraper end 132 contacts the cleaning portion 111 is approximately the same distance from the rotation axis R. In this way, it is possible to avoid the different spacings between the scraper 130 and the cleaning portion 111, which would result in a deterioration in the performance of receiving dirty liquid over the entire span of the third direction D3. In addition, the distance from the first scraper end 131 to the second scraper end 132 of the scraper 130 is the same, so that the width of the scraper 130 is uniform.

[0057] Figure 3A FIG. 1 shows a schematic diagram of an example arc-shaped water blocking member 120 and a scraper 130 according to an embodiment of the present disclosure at a front view angle. Figure 3A As shown, the arcuate water-blocking member 120 further includes an opening 124 in the middle of the third direction D3 for guiding waste liquid in the water storage chamber out of the water storage chamber. The opening 124 extends from the side of the arcuate water-blocking member 120 facing the rotating drum 110 to the side facing away from the rotating drum 110, thereby connecting the water storage chamber to the outside of the cleaning assembly 100. The arcuate water-blocking member 120 also includes a front wall 126 in the second direction D2 of the path of the electrical device. The front wall 126 extends from the top of the arcuate water-blocking member 120 in a direction away from the top. The front wall 126 has a V-shaped lower edge in the third direction D3. The tip of the V-shaped lower edge is located in the middle of the opening 124. In this embodiment, to match this lower edge, the scraper 130 also has a V-shape in the third direction D3 to match the shape of the front wall 126 and is capable of guiding waste liquid in the water storage chamber to flow to the opening 124 under the action of gravity.

[0058] The V-shaped lower edge of the front wall 126 is connected to a scraper 130. The surface of the scraper 130 corresponds to the shape of the lower edge of the front wall 126 and is tightly connected. Furthermore, the arcuate water blocking member 120 includes end caps 128-1 and 128-2 at both ends, located in the third direction D3. One end cap 128-2 is provided with a rotating shaft 129 for supporting the rotating drum 110.

[0059] Figure 3B Schematic diagram of an example curved water blocking member and a scraper 130 according to an embodiment of the present disclosure is shown in FIG. The curved water blocking member 120 includes an inner front wall 125 of a front wall 126 located in the water storage cavity. Figure 3B In the embodiment, most of the inner front wall 125 is obscured by the scraper 130 connected to the front wall 126 and is not shown. The scraper 130 extends in a U-shape in a third direction D3 parallel to the rotation axis R, and the bottom of the U-shape extends in a direction away from the drum 110. A through hole 134 is also provided on the scraper 130. Correspondingly, a threaded hole can be provided at a corresponding position on the end 122 of the second water-blocking member, and a threaded fastener such as a bolt or a screw can be screwed into the threaded hole 134 through an opening on the scraper 130 to fix the scraper 130 at the end 122 of the second water-blocking member. In an alternative embodiment, the scraper 130 can be integrally formed with the arc-shaped water-blocking member 120. As a result, the installation and fixing structure is saved, thereby simplifying the installation and improving the sealing.

[0060] Figure 3C FIG. 1 shows a schematic diagram of an example arc-shaped water blocking member 120 and a scraper 130 according to an embodiment of the present disclosure at a side oblique angle. Figure 3C As shown, the scraper 130 is bent in a direction opposite to the traveling direction D2, and at the same time, the scraper 130 is bent downward in the vertical direction so as to be able to fit on the cylindrical surface of the cleaning portion of the drum.

[0061] Here, the corresponding structure of the cleaning component is described, and the following will refer to Figures 4A to 4F To describe the operating principle of the cleaning component when performing a cleaning operation. Figures 4A-4F Schematic diagrams of various stages of an example cleaning process performed by a cleaning assembly according to an embodiment of the present disclosure are shown. For clarity, Figures 4A to 4F Only components associated with the cleaning component performing the cleaning operation are shown.

[0062] Figure 4A FIG. 4 is a schematic diagram illustrating a first stage 400A of a cleaning assembly according to an embodiment of the present disclosure. Figure 4AAs shown, the cleaning assembly 100 includes a rotating drum 110. The rotating drum 110 includes a cleaning portion 111 that rotates about a rotation axis R in a first direction D1. A scraper 130 is provided at the front of the cleaning portion 111 in a second direction D2 of travel of the cleaning assembly 100, in interference contact with the cleaning portion 111. The scraper 130 is fixed to the curved water-blocking member 120 and, together with the end cap 128, the inner front wall 125, and the top of the curved water-blocking member 120, forms a water storage chamber. The cleaning assembly 100 travels along the second direction D2 with the electrical device over the surface 20 to be cleaned. Dust 410, ketchup 420, and melon seed shells 430 are present on the surface 20 to be cleaned.

[0063] As the cleaning assembly 110 moves forward, the cleaning portion 111 contacts the surface to be cleaned 20 and absorbs dirt and liquid contaminants from the surface 20. Dust 410 includes dust 411 on the surface to be cleaned 20 that has not yet been absorbed, dust 412 on the cleaning portion 111, and dust 413 scraped from the cleaning portion 111 by the scraper 130. At this point, liquid contaminants are present on the scraper 130. As the liquid contaminants accumulate on the scraper 130 and are guided by the U-shaped inner front wall 125, they form a liquid contaminant flow that flows toward the central opening 124. This liquid contaminant flow can draw dirt from the scraper 130, carrying it to the opening 124 and allowing it to enter the liquid contaminant storage element from the opening 124.

[0064] Figure 4B FIG. 4 is a schematic diagram illustrating a second stage 400B performed by a cleaning assembly according to an embodiment of the present disclosure. Figure 4B As shown, the dust 411 on the surface to be cleaned 20 has been cleaned, and some dust 412 still exists on the cleaning portion 111. The dust 413 on the scraper 130 has entered the dirty liquid storage member through the opening 124 along with the dirty liquid flow.

[0065] Afterwards, the cleaning assembly 100 continues to move along the second direction D2. Figure 4C FIG. 4 is a schematic diagram illustrating a third stage 400C performed by a cleaning assembly according to an embodiment of the present disclosure. Figure 4C As shown, ketchup 420 has been cleaned by cleaning unit 111, resulting in a portion of ketchup 421 located on the cleaning unit and a portion of ketchup 422 located on scraper 130. After being scraped from cleaning unit 111 onto scraper 130, ketchup 422 enters the waste liquid flow. After entering the waste liquid flow, ketchup 422 is diluted, reducing its viscosity and allowing it to flow smoothly with the waste liquid flow toward opening 124.

[0066] The cleaning assembly 100 continues to move along the second direction D2. Figure 4DFIG. 4 is a schematic diagram illustrating a fourth stage 400D performed by a cleaning assembly according to an embodiment of the present disclosure. Figure 4D As shown, part of the ketchup 421 on the cleaning portion has been completely scraped onto the scraper 130. Part of the ketchup 422 on the scraper 130 enters the dirty liquid storage member through the opening 124 along with the dirty liquid flow.

[0067] The cleaning assembly 100 continues to move along the second direction D2. Figure 4E FIG. 4 is a schematic diagram illustrating a fifth stage 400E performed by a cleaning assembly according to an embodiment of the present disclosure. Figure 4E As shown, the ketchup 420 has been completely washed into the dirty liquid storage member, and the melon seed slices 430 have been delivered to the scraper 130. Since the scraper 130 has a certain length, the water storage cavity formed can accommodate the melon seed slices 430 and move them toward the opening 124 in the formed dirty liquid flow.

[0068] The cleaning assembly 100 continues to move along the second direction D2. Figure 4F FIG. 4 is a schematic diagram illustrating a sixth stage 400F performed by a cleaning assembly according to an embodiment of the present disclosure. Figure 4F As shown, the melon seed pieces 430 on the scraper 130 have entered the opening 124 and will soon be flushed into the dirty liquid storage member.

[0069] according to Figures 4A to 4F In this embodiment, small dust particles, sticky tomato paste, and large melon seed shells can all be smoothly transported into the dirty liquid storage element within the water storage chamber along with the resulting dirty liquid flow. Because the scraper replaces most of the cleaning portion adjacent to the scraper to form the water storage chamber, the contact time between the cleaning portion and the dirty liquid is reduced, significantly improving the cleanliness of the cleaning portion and enhancing cleaning efficiency.

[0070] In some embodiments, the electrical device also features a self-cleaning function for the cleaning component. For example, after the self-cleaning function is activated, the electrical device moves to a charging base or a self-cleaning base to ensure the scrubber is stable. Then, the self-cleaning function begins. During the cleaning process, the electrical device automatically cleans the cleaning portion of the rotating drum. This involves continuously spraying clean water onto the cleaning portion while the drum rotates at high speed. During this process, the clean water sprayed onto the cleaning portion is carried by the cleaning portion into a water reservoir formed by the inner front wall of the scraper and the top of the curved water-blocking member. Guided by the inner front wall, the cleaning liquid forms a stream that flows into the opening and is discharged. This resulting stream of cleaning liquid effectively flushes the walls of the water reservoir, achieving efficient self-cleaning. Furthermore, compared to manual cleaning, the self-cleaning function provides a more thorough cleaning of the roller brush, improving the scrubber's cleaning performance. Regular cleaning of the roller brush reduces wear and corrosion on the cleaning portion, extending its service life. It also prevents stains and bacteria from growing on the cleaning portion, which could damage other components of the electrical device, thereby extending the overall service life of the scrubber.
