[0031] To make the objectives, technical solutions, and advantages of the present disclosure more clear, the present disclosure will be further described in detail below with reference to the accompanying drawings. It is apparent that the embodiments described are only a portion of the embodiments of the present disclosure, rather than all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present disclosure without creative effort are intended to fall within the scope of protection of the present disclosure.

[0032] The terms used in the embodiments of the present disclosure are for the purpose of describing specific embodiments only and are not intended to limit the present disclosure. The singular forms "a," "the," and "the" used in the embodiments of the present disclosure and the appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise. "A variety of" generally includes at least two, and other quantifiers are similar.

[0033] It should be understood that although the terms "first," "second," "third," etc. may be used to describe in the present disclosure, these descriptions should not be limited to these terms. These terms are only used to distinguish the objects being described. For example, without departing from the scope of the present disclosure, the first may also be referred to as the second, and similarly, the second may also be referred to as the first. In addition, the terms "first," "second," "third," etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance.

[0034] It should be understood that the term "and / or" as used herein is merely a description of an association between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, and B exists alone. Furthermore, the character " / " as used herein generally indicates that the associated objects are in an "or" relationship. The singular forms "a," "the," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.

[0035] In the description of this disclosure, it should be noted that, unless otherwise expressly specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; and direct connections or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0036] It should also be noted that the terms "include," "comprises," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a product or device comprising a series of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such product or device. In the absence of further limitations, an element defined by the phrase "comprises a..." does not exclude the presence of other identical elements in the product or device comprising the element.

[0037] In the related art, because the cleaning brush head is not equipped with a fool-proof structure, when the user installs the roller brush cover on the floating bracket, it is easy for the roller brush cover to be installed upside down or the connection between the roller brush cover and the floating bracket to be misaligned. When the roller brush cover is installed on the floating bracket, the roller brush cover button is engaged with the roller brush cover button slot on the floating bracket, but the roller brush cover claw is not accurately engaged with the roller brush cover claw on the floating bracket. Instead, it rests on the highest point of the floating bracket, forming a lever support, which prevents the roller brush cover from falling off. In this incorrect connection method, since the roller brush cover is not properly assembled, users will encounter problems such as loud noises during use and the roller brush cover scratching the floor.

[0038] Therefore, the utility model designs a cleaning brush head and a cleaning device with a fool-proof structure, which can effectively avoid the problems of loud working noise of the roller brush and scratching of the floor by the roller brush cover due to improper assembly of the roller brush cover and the floating bracket.

[0039] Based on the above description, the utility model provides a cleaning brush head and a cleaning device, wherein the cleaning brush head includes: a floating bracket, provided with a clamping groove and a front end claw groove; a roller brush cover, provided with a clamping piece and a front end claw, which are respectively clamped with the clamping groove and the front end claw groove, and are configured to connect the roller brush cover to the floating bracket; an anti-foolproof structure, including an anti-foolproof positioning piece and an anti-foolproof positioning groove, wherein the anti-foolproof positioning piece is detachably connected to the anti-foolproof positioning groove, and is configured such that when the anti-foolproof positioning piece is connected to the anti-foolproof positioning groove, the clamping piece and the front end claw are respectively connected to the clamping groove and the front end claw groove.

[0040] Optional embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

[0041] A first aspect of the present disclosure provides a cleaning brush head, such as Figure 1 As shown, it includes a floating bracket 100 , a roller brush cover 200 and an anti-fool structure 400 .

[0042] In some embodiments, as Figure 2 As shown, the floating bracket 100 is provided with a receiving groove 101, and the receiving groove 101 is used to receive at least one roller brush 300. The roller brush 300 can be constructed as a cylindrical structure, and the side surface of the cylinder contacts the cleaning surface for cleaning the contaminated area.

[0043] In some embodiments, a roller brush 300 may be disposed in the receiving groove 101, and the foolproof structure 400 is disposed at both ends of the receiving groove 101. When the roller brush cover 200 is connected to the floating bracket 100, the foolproof structure 400 can prevent the roller brush cover 200 from being installed upside down or otherwise improperly.

[0044] It should be noted that the present disclosure does not specifically limit the number of the receiving grooves 101 and the roller brushes 300. The receiving grooves 101 may be provided with one, two, or more. In the receiving groove 101, one, two, or more roller brushes 300 arranged in parallel may be accommodated.

[0045] In some embodiments, the floating bracket 100 can be connected to the roller brush cover 200 to keep the roller brush 300 in the correct installation position, ensuring that the roller brush 300 rotates quickly in the floating bracket 100 to clean the cleaning surface without causing the roller brush cover 200 to scratch the cleaning surface.

[0046] In some embodiments, the floating bracket 100 is provided with a snap-in slot 110. The snap-in slot 110 is provided on a side of the floating bracket 100 facing the roller brush cover 200. A first snap-in hook is provided inside the snap-in slot 110 and is configured to snap-in with at least a portion of the roller brush cover 200 to ensure a stable connection between the floating bracket 100 and the roller brush cover 200.

[0047] In some embodiments, there may be multiple snap-in slots 110 , and the slot entrances of the multiple snap-in slots 110 are all facing the side where the roller brush cover 200 is located, and are configured to be connected to the roller brush cover 200 . The multiple snap-in slots 110 can make the connection between the floating bracket 100 and the roller brush cover 200 more stable.

[0048] In some embodiments, the floating bracket 100 is provided with a front claw groove 120. The front claw groove 120 is located at one end of the floating bracket 100 and is recessed toward a side away from the roller brush 300. The front claw groove 120 is adapted to accommodate at least a portion of the roller brush cover 200, so that one end of the roller brush cover 200 abuts against the end of the floating bracket 100. Furthermore, the roller brush cover 200 abuts against one end of the floating bracket 100 and rotates until the roller brush cover 200 engages with the floating bracket 100.

[0049] In some embodiments, the floating support 100 further includes a limiting portion 130, such as Figure 1 As shown, the limiting portion 130 is provided at one end of the front claw groove 120 away from the roller brush 300. The thickness direction of the floating bracket 100 is designated as a first direction. That is, in the first direction, the projection of the limiting portion 130 covers at least a portion of the front claw groove 120, so that at least a portion of the roller brush cover 200 is engaged with the front claw groove 120, thereby limiting the rotation center and rotation angle of the roller brush cover 200.

[0050] In some embodiments, the roller brush cover 200 is provided with a clip 210, and the clip 210 matches the clip groove 110, and is suitable for moving toward the clip groove 110 under the action of external force and clipping with the clip groove 110, thereby realizing a stable connection between the floating bracket 100 and the roller brush cover 200.

[0051] Specifically, the latching member 210 includes a handle, an elastic member, and a second latching hook. The second latching hook has an initial position and a pressing position. When the second latching hook is in the initial position, the second latching hook is engaged with the first latching hook. When the second latching hook is in the pressing position, the second latching hook is separated from the first latching hook.

[0052] The buckle handle is connected to the second clamping hook through the elastic member, and is configured to press the buckle handle under the action of an external force to switch the second clamping hook from an initial position to a pressing position.

[0053] When the buckle is not affected by external force, the elastic part is relaxed and the second snap-fit hook is always in the initial position; when the buckle is affected by external force, the elastic part is compressed and the second snap-fit hook switches from the initial position to the pressing position as the external force increases.

[0054] It should be separately explained that the above embodiments are merely exemplary embodiments, and the present disclosure does not limit the shape and structure of the clip 210. The clip 210 may also be any other structural component having a second clip hook that can be connected to the first clip hook.

[0055] In some embodiments, the clamping member 210 may be provided in plurality, and the plurality of clamping members 210 correspond one-to-one to the plurality of the clamping grooves 110 and are configured to be clamped with the clamping grooves 110 under the action of external force to make the connection between the floating bracket 100 and the roller brush cover 200 more stable.

[0056] In some embodiments, the roller brush cover 200 is further provided with a stop portion 230 and a front end claw 220. The stop portion 230 and the front end claw 220 are configured in an L-shaped structure. The stop portion 230 extends in the thickness direction of the roller brush cover 200, and the front end claw 220 is provided at one end of the stop portion 230 and is configured to be installed in the front end claw groove 120.

[0057] During the process of installing the front end claw 220 in the front end claw groove 120, after the front end claw 220 is installed in the front end claw groove 120, at least part of the stop portion 230 stops at the limiting portion 130, so that the roller brush cover 200 has a rotation center and rotates stably, and is configured to connect the roller brush cover 200 to the floating bracket 100.

[0058] Specifically, when the front end claw 220 is installed in the front end claw groove 120, the claw part is first extended into the front end claw groove 120, so that the stop part 230 and the limiting part 130 are abutted, so as to further rotate the stop part 230 of the roller brush cover 200 with the stop position of the limiting part 130 as the rotation center, so that the roller brush cover 200 is rotated until the clamping part 210 is clamped with the clamping groove 110, so that the roller brush cover 200 is fitted with the floating bracket 100, thereby realizing the connection between the roller brush cover 200 and the floating bracket 100.

[0059] In some embodiments, the edge of the front claw 220 facing the front claw groove 120 may be chamfered to facilitate connection between the front claw 220 and the front claw groove 120, thereby avoiding unnecessary mechanical wear caused by unnecessary installation or removal of the roller brush cover 200. The chamfered edge helps to avoid extrusion and friction between the sharp corners and the steel plate being brushed with glue, reduces the compressive stress of the parts, improves the surface quality, prevents the workpiece edge from cracking, and improves the toughness and service life of the parts.

[0060] In some embodiments, in order to avoid the roller brush cover 200 being installed upside down or the roller brush cover 200 and the floating bracket 100 being improperly assembled, which may cause the user to encounter problems such as loud noises from the roller brush 300 or even scratching the floor during use, the cleaning brush head provided in the embodiment of the present disclosure also includes an anti-fool structure.

[0061] In some embodiments, the fool-proofing structure 400 includes an anti-fool-proofing positioning member 410 and an anti-fool-proofing positioning groove 420. The anti-fool-proofing positioning member 410 and the anti-fool-proofing positioning groove 420 match in shape. The anti-fool-proofing positioning member 410 can be installed inside the anti-fool-proofing positioning groove 420 to enable the anti-fool-proofing structure 400 to be connected normally.

[0062] Specifically, the foolproof positioning member 410 is detachably connected to the foolproof positioning slot 420. When the foolproof positioning member 410 is connected to the foolproof positioning slot 420, the clamping member 210 and the front claw 220 are respectively connected to the clamping slot 110 and the front claw slot 120, and the roller brush cover 200 and the floating bracket 100 are properly assembled. If the foolproof positioning member 410 cannot be installed in the foolproof positioning slot 420, the roller brush cover 200 and the floating bracket 100 will not be properly assembled, and the cleaning brush head will not function properly.

[0063] In some embodiments, the foolproof positioning member 410 is an arc-shaped structural member. Correspondingly, the foolproof positioning groove 420 can be an arc-shaped groove having the same curvature as that of the foolproof positioning member 410 .

[0064] Since the anti-foolproof positioning member 410 and the anti-foolproof positioning groove 420 are arc-shaped structural members and arc-shaped grooves, during the connection between the roller brush cover 200 and the floating bracket 100, if the installation directions are opposite, the two arc-shaped structural members cannot be installed in the sleeve, that is, the anti-foolproof positioning member 410 cannot be installed inside the anti-foolproof positioning groove 420, which can effectively avoid the roller brush cover 200 and the floating bracket 100 from being improperly assembled due to the reverse installation of the roller brush cover 200, resulting in loose roller brush 300, loud working noise, and the roller brush cover 200 scratching the bottom plate.

[0065] In some embodiments, the arc-shaped structural member and the arc-shaped groove are both arc-shaped, and the center of the arc is the rotation center of the roller brush cover 200 when assembled on the floating bracket 100, that is, the stop position of the stop portion 230 and the limit portion 130.

[0066] In response to the front end claw 220 of the roller brush cover 200 being inserted into the front end claw groove 120, the stop portion 230 of the roller brush cover 200 abuts against the limiting portion 130 of the floating bracket 100. At this time, the roller brush cover 200 is rotated with the stop position as the center of the circle, so that the foolproof positioning member 410 enters the inside of the foolproof positioning groove 420 from the entrance of the foolproof positioning groove 420. The foolproof positioning member 410 extends along the arc path inside the foolproof positioning groove 420, so that the foolproof positioning member 410 is installed inside the foolproof positioning groove 420 until the roller brush cover 200 and the floating bracket 100 are in contact, so that the connecting member 210 of the roller brush cover 200 is engaged with the connecting groove 110 of the floating bracket 100, thereby achieving accurate assembly of the roller brush cover 200 and the floating bracket 100.

[0067] In some embodiments, the curvature of the foolproof positioning member 410 should not exceed 50 degrees. If the curvature of the foolproof positioning member 410 is larger, the curvature of the corresponding foolproof positioning groove 420 will also increase. In addition, since the foolproof positioning groove 420 is disposed outside the foolproof positioning member 410 during assembly, the overall size of the foolproof positioning groove 420 is slightly larger than the foolproof positioning member 410. Therefore, if the curvature of the foolproof positioning member 410 exceeds 50 degrees, the foolproof positioning groove 420 will occupy a larger space on the cleaning brush head, which may lead to problems such as an increase in the size of the brush head and inconvenience in connection.

[0068] In some embodiments, when the fool-proof positioning member 410 is installed inside the fool-proof positioning groove 420, the gap between the fool-proof positioning member 410 and the side wall of the fool-proof positioning groove 420 does not exceed 1 mm.

[0069] If the gap is too large, the connection between the roller brush cover 200 and the floating bracket 100 may be unstable. In addition, when the cleaning roller brush 300 is in operation, a large gap between the roller brush cover 200 and the floating bracket 100 may increase the operating noise of the roller brush 300.

[0070] If the gap is too small, for example, the gap between the anti-foolproof positioning piece 410 and the side wall of the anti-foolproof positioning groove 420 is 0.01 mm, it is easy to cause problems such as difficulty in alignment or difficulty in moving the anti-foolproof positioning piece 410 into the anti-foolproof positioning groove 420 during the installation process.

[0071] In some embodiments, the end of the fool-proof positioning member 410 is provided with a first rounded corner or a first beveled corner, and the first rounded corner or the first beveled corner is configured to facilitate insertion into the fool-proof positioning groove 420.

[0072] Since the anti-fouling positioning member 410 needs to be installed in the anti-fouling positioning groove 420, during the process of aligning the anti-fouling positioning member 410 with the anti-fouling positioning groove 420, the end of the anti-fouling positioning member 410 is easily rubbed against the entrance of the anti-fouling positioning groove 420 under the action of external force. In the field of mechanics and design, sharp corners may cause stress concentration, while rounded corners can disperse force, reduce wear and damage, extend service life, and reduce damage and maintenance costs, thereby improving durability and safety.

[0073] In some embodiments, the entrance of the fool-proof positioning groove 420 is provided with a second rounded corner or a second beveled corner, and the second rounded corner or the second beveled corner is configured to facilitate the insertion of the fool-proof positioning member 410 into the fool-proof positioning groove 420 .

[0074] The second rounded corner or the second beveled corner can match the first rounded corner or the first beveled corner of the anti-foolproof positioning member 410, enhancing aesthetics and visual comfort. The corresponding rounded corners or beveled corners in the mechanical structure are more in line with engineering principles, can guide the user's line of sight, and make it easier for the user to determine whether the first rounded corner and the second rounded corner match each other, providing a better user experience and a sense of quality.

[0075] In some embodiments, the foolproof structure 400 includes a first foolproof structure and a second foolproof structure, such as Figure 2 As shown, the first fool-proof structure and the second fool-proof structure are respectively provided at both ends of the floating bracket 100 and the roller brush cover 200 .

[0076] When the front end claw 220 of the roller brush cover 200 is extended into the front end claw groove 120, and the stop portion 230 of the roller brush cover 200 abuts against the limiting portion 130 of the floating bracket 100, the roller brush cover 200 rotates with the stop position as the center of the circle, so that the anti-foolproof positioning member 410 enters the interior of the anti-foolproof positioning groove 420 from the entrance of the anti-foolproof positioning groove 420.

[0077] The fool-proof positioning members 410 of the first and second fool-proof structures extend along the arc path inside the fool-proof positioning groove 420, so that the fool-proof positioning members 410 are installed inside the fool-proof positioning groove 420 until the roller brush cover 200 is fitted with the floating bracket 100, so that the clamping member 210 of the roller brush cover 200 is clamped with the clamping groove 110 of the floating bracket 100, thereby realizing accurate assembly of the roller brush cover 200 and the floating bracket 100.

[0078] During the installation of the roller brush cover 200, the cleaning brush head provided with a foolproof structure 400 is subjected to greater pressure. Repeated installation and removal steps may cause the gap between the foolproof positioning piece 410 and the foolproof positioning groove 420 to increase, and even shorten the service life of the roller brush cover 200. Compared with the embodiment in which a single foolproof structure 400 is provided in the cleaning brush head, the cleaning brush head provided in this embodiment is provided with two foolproof structures 400, which can make the roller brush cover 200 rotate more smoothly. The two sides of the roller brush cover 200 have a balanced rotational torque, which can prevent the foolproof structure 400 on one side of the roller brush cover 200 from being subjected to greater pressure during rotation.

[0079] In some embodiments, the roller brush 300 is provided with two, such as Figure 2 As shown, the two roller brushes 300 are arranged side by side in the receiving groove 101, and the fool-proof positioning mechanism is arranged between the two roller brushes 300.

[0080] Specifically, the width direction of the floating bracket 100 is designated as the second direction, in which the two roller brushes 300 are arranged side by side. The foolproof positioning groove 420 can be provided between the two roller brushes 300, and the foolproof positioning groove 420 does not interfere with the normal rotation of the roller brushes 300.

[0081] The anti-foolproof positioning member 410 can be set on the roller brush cover 200. The anti-foolproof positioning member 410 is located opposite the anti-foolproof positioning groove 420 and can be installed into the anti-foolproof positioning groove 420 under the action of external force to ensure that the roller brush cover 200 and the floating bracket 100 are correctly assembled.

[0082] In some embodiments, as Figure 1 As shown, the foolproof positioning groove 420 can be provided on the floating bracket 100 ; the foolproof positioning member 410 can be provided on the roller brush cover 200 .

[0083] During the process of connecting the roller brush cover 200 with the floating bracket 100, the front end claw 220 of the roller brush cover 200 is first extended into the front end claw groove 120, so that the stop portion 230 of the roller brush cover 200 is stopped with the limiting portion 130 of the floating bracket 100. Furthermore, the roller brush cover 200 is rotated with the stop position of the stop portion 230 and the limiting portion 130 as the center, and the rotation center is the center of the arc of the anti-foolproof positioning member 410.

[0084] As the roller brush cover 200 rotates around the center of the circle, the anti-foolproof positioning piece 410 enters the interior of the anti-foolproof positioning groove 420 from the entrance of the anti-foolproof positioning groove 420, and the anti-foolproof positioning piece 410 extends along the arc path inside the anti-foolproof positioning groove 420, so that the anti-foolproof positioning piece 410 is installed inside the anti-foolproof positioning groove 420 until the roller brush cover 200 is fitted with the floating bracket 100, so that the clamping piece 210 of the roller brush cover 200 is clamped with the clamping groove 110 of the floating bracket 100, thereby realizing accurate assembly of the roller brush cover 200 and the floating bracket 100.

[0085] In other embodiments, the positions of the fool-proof positioning member 410 and the fool-proof positioning groove 420 can be interchanged, that is, the fool-proof positioning groove 420 is provided on the roller brush cover 200 , and the fool-proof positioning member 410 is provided on the floating bracket 100 .

[0086] Similarly, in the process of connecting the roller brush cover 200 with the floating bracket 100, the front end claw 220 of the roller brush cover 200 is first extended into the front end claw groove 120, so that the stop portion 230 of the roller brush cover 200 is stopped with the limiting portion 130 of the floating bracket 100. Furthermore, the roller brush cover 200 is rotated with the stop position of the stop portion 230 and the limiting portion 130 as the center, and the rotation center is the center of the arc of the anti-foolproof positioning member 410.

[0087] As the roller brush cover 200 rotates around the center of the circle, the anti-foolproof positioning piece 410 enters the interior of the anti-foolproof positioning groove 420 from the entrance of the anti-foolproof positioning groove 420, and the anti-foolproof positioning piece 410 extends along the arc path inside the anti-foolproof positioning groove 420, so that the anti-foolproof positioning piece 410 is installed inside the anti-foolproof positioning groove 420 until the roller brush cover 200 is fitted with the floating bracket 100, so that the clamping piece 210 of the roller brush cover 200 is clamped with the clamping groove 110 of the floating bracket 100, thereby realizing accurate assembly of the roller brush cover 200 and the floating bracket 100.

[0088] In other embodiments, Figure 2 As shown, on the floating bracket 100, the anti-foolproof positioning piece 410 and the anti-foolproof positioning groove 420 can be respectively arranged on both sides of the roller brush 300, and correspondingly, the roller brush cover 200 is provided with an anti-foolproof positioning groove 420 and an anti-foolproof positioning piece 410 corresponding to the anti-foolproof positioning piece 410 and the anti-foolproof positioning groove 420.

[0089] Furthermore, the anti-foolproof positioning piece 410 is installed inside the anti-foolproof positioning groove 420 until the roller brush cover 200 is fitted with the floating bracket 100, so that the clamping piece 210 of the roller brush cover 200 is clamped with the clamping groove 110 of the floating bracket 100, thereby achieving accurate assembly of the roller brush cover 200 and the floating bracket 100.

[0090] In some embodiments, the anti-fouling positioning member 410 and the roller brush cover 200 or the floating bracket 100 are separate structures.

[0091] The foolproof positioning member 410 is detachably connected to the roller brush cover 200 or the floating bracket 100. For example, a first slide groove is provided at the location where the roller brush cover 200 and the foolproof positioning member 410 are connected. Correspondingly, a first slider can be provided on the side where the foolproof positioning member 410 is connected to the roller brush cover 200. The first slider matches the first slide groove and is detachably connected to the first slide groove of the roller brush cover 200.

[0092] Similarly, the removable structure of the anti-fouling locating member 410 attached to the floating bracket 100 is similar to the removable connection structure described above. For example, a second slide groove is provided at the location where the floating bracket 100 connects to the anti-fouling locating member 410. Correspondingly, a second slider can be provided on the side where the anti-fouling locating member 410 connects to the floating bracket 100. The second slider mates with the second slide groove and is removably connected to the second slide groove of the floating bracket 100.

[0093] The split connection between the anti-foolproof positioning piece 410 and the roller brush cover 200 or the floating bracket 100 is more flexible. If the anti-foolproof positioning groove 420 is blocked during the installation of the roller brush cover 200 and the anti-foolproof positioning piece 410 cannot be installed inside the anti-foolproof positioning groove 420, the anti-foolproof positioning piece 410 can be removed to achieve the fit between the roller brush cover 200 and the floating bracket 100, and the cleaning brush head can be assembled by clamping the clamping piece 210 with the clamping groove 110.

[0094] It should be noted that the above-mentioned split structure is exemplary, and any other connection structure may be used to achieve a detachable connection between the anti-foolproof positioning member 410 and the roller brush cover 200 or the floating bracket 100, such as magnetic attraction, snap connection, threaded connection, etc.

[0095] In some embodiments, the anti-fouling positioning member 410 is an integral structure with the roller brush cover 200 or the floating bracket 100 .

[0096] During the production and processing stage, the anti-fouling positioning member 410 and the roller brush cover 200 are an integrated structure, which can reduce the production difficulty during the processing and help improve production efficiency.

[0097] During the user use stage, the integrated structural part has higher rigidity and compressive strength, and when used in usage scenarios similar to cleaning brush heads, since the cleaning brush head needs to rotate the roller brush 300 at high speed to clean the cleaning surface during use, it is inevitable that a certain vibration intensity will be generated on the shell. When the anti-foolproof positioning part 410 and the roller brush cover 200 are an integrated structure, they have good shock resistance and durability, avoiding damage to the mechanical parts of the anti-foolproof structure due to the high-intensity vibration of the cleaning brush head during operation. The integrated structural part is not only practical, but also can use template technology to customize different appearances and colors according to customer needs, meet the diversified needs of the market, and create more aesthetically pleasing products.

[0098] Similarly, when the foolproof positioning member 410 can also be a separate structure or an integrated structure with the floating bracket 100, the installation method and structure of the two are similar to the installation of the foolproof structure 400 and the roller brush cover 200, so they will not be repeated here.

[0099] In some embodiments, the anti-fouling positioning member 410 is made of plastic, metal or alloy material.

[0100] Plastic is a relatively lightweight material, making it suitable for use in products requiring reduced weight. Plastic also offers excellent chemical stability, corrosion resistance, electrical insulation, low thermal conductivity, and sound and vibration dampening properties.

[0101] In addition, plastics also possess high specific strength and a wide distribution of mechanical strength: Mechanical properties such as hardness, tensile strength, elongation, and impact strength are widely distributed, offering a wide range of applications. Plastics have a high specific strength due to their low specific gravity and high strength.

[0102] The anti-foolproof positioning member 410 supported by metal materials or alloy materials has better mechanical strength, is firm, pressure-resistant, can be bitten, can be welded, and has excellent moisture resistance and air tightness.

[0103] In other embodiments, the floating bracket 100 includes a through hole 102 , which is disposed at an end of the front end claw groove 120 away from the roller brush 300 and is configured to connect the front end claw groove 120 to the outside.

[0104] The roller brush cover 200 includes an extension portion disposed at an end of the front end claw 220 away from the clamping member 210, extending away from the clamping member 210. Furthermore, after the front end claw 220 is mounted in the front end claw slot 120, the end of the front end claw 220 passes through the through hole 102 and extends away from the roller brush 300. The extension portion is configured such that when the extension portion passes through the through hole 102, the clamping member 210 and the front end claw 220 are connected to the clamping slot 110 and the front end claw slot 120, respectively.

[0105] The roller brush cover 200 provided in this embodiment has an extension portion, which increases the overall width of the roller brush cover 200. During installation of the roller brush cover 200 on the floating bracket 100, the extension portion needs to be passed through the through-hole 102 so that the front claw 220 is installed within the front claw groove 120. With the front claw 220 installed within the front claw groove 120, the clamping member 210 of the roller brush cover 200 and the clamping groove 110 of the floating bracket 100 are aligned. External force can be applied to engage the clamping member 210 with the clamping groove 110, ensuring accurate fit between the roller brush cover 200 and the floating bracket 100.

[0106] Since the setting of the extension portion increases the overall width of the roller brush cover 200, if the extension portion does not pass through the through hole 102 or the front end claw 220 is not installed in the front end claw groove 120, the clamping member 210 and the clamping groove 110 are in a misaligned state, that is, the roller brush cover 200 cannot be clamped with the floating bracket 100, which can realize the anti-foolproof function during the installation of the roller brush cover 200.

[0107] The floating bracket 100 and the roller brush cover 200 provided in this embodiment can be used alone in the cleaning brush head to achieve a fool-proof effect, or can work together with the fool-proof structure 400 on the cleaning brush head to achieve a fool-proof effect during the installation of the cleaning brush head.

[0108] A second aspect of the embodiments of the present disclosure provides a cleaning device, comprising the cleaning brush head described in the first aspect of the embodiments of the present disclosure.

[0109] After the cleaning brush head is installed in conjunction with the cleaning device, since the cleaning brush head has an anti-foolproof structure 400, the assembly of the anti-foolproof positioning part 410 and the anti-foolproof positioning groove 420 in the anti-foolproof structure 400 can effectively avoid the problems of loud working noise of the roller brush 300 and scratching of the cleaning surface by the roller brush cover 200 due to improper assembly of the floating bracket 100 and the roller brush cover 200, which is beneficial to improving the user experience.

[0110] The specific structure, working principle, and beneficial effects of the cleaning brush head and cleaning device provided by the embodiments of the present disclosure can be referred to the cleaning brush head and cleaning device described in any of the above embodiments and will not be elaborated here.

[0111] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on its differences from other embodiments. References to the common and similar parts between the various embodiments will be sufficient. For the systems or devices disclosed in the embodiments, since they correspond to the methods disclosed in the embodiments, their descriptions are relatively simple; for relevant details, refer to the descriptions of the methods.
