Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of this disclosure clearer, the disclosure will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0031] The terminology used in the embodiments of this disclosure is for the purpose of describing particular embodiments only and is not intended to limit the disclosure. The singular forms “a,” “the,” and “the” as used in the embodiments of this disclosure and the appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise; “multiple” generally includes at least two, and other quantifiers are similarly intended.

[0032] It should be understood that although the terms first, second, third, etc., may be used to describe embodiments of this disclosure, these descriptions should not be limited to these terms. These terms are only used to distinguish the described objects. For example, first may also be referred to as second without departing from the scope of embodiments of this disclosure, and similarly, second may also be referred to as first. Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0033] It should be understood that the term "and / or" as used herein is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, and B alone. Additionally, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship. The singular forms "a," "the," and "the" are also intended to include the plural forms unless the context clearly indicates otherwise.

[0034] In the description of this disclosure, it should be noted that, unless otherwise expressly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this disclosure based on the specific circumstances.

[0035] It should also be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that an article or device that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such an article or device. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the article or device that includes said element.

[0036] In related technologies, because the cleaning brush head lacks a foolproof design, users often install the roller brush cover backwards or with misalignment when attaching it to the floating bracket. When the roller brush cover is installed, the button on the roller brush cover engages with the button slot on the floating bracket, but the claws on the roller brush cover do not engage precisely with the claws on the floating bracket. Instead, they rest on the highest point of the floating bracket, creating a lever support and preventing the roller brush cover from detaching. With this incorrect connection, the improperly assembled roller brush cover can cause problems such as excessive noise during operation and scratches on the floor.

[0037] Therefore, this disclosure presents a cleaning brush head and cleaning device with a foolproof 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.

[0038] Based on the above description, this disclosure provides a cleaning brush head and a cleaning device. The cleaning brush head includes: a floating support with a snap-fit ​​groove and a front-end claw groove; a roller brush cover with a snap-fit ​​component and a front-end claw, which snap-fit ​​into the snap-fit ​​groove and the front-end claw groove respectively, configured to connect the roller brush cover to the floating support; and a foolproof structure including a foolproof positioning component and a foolproof positioning groove, wherein the foolproof positioning component is detachably connected to the foolproof positioning groove, configured such that when the foolproof positioning component is connected to the foolproof positioning groove, the snap-fit ​​component and the front-end claw are respectively connected to the snap-fit ​​groove and the front-end claw groove.

[0039] The optional embodiments of this disclosure are described in detail below with reference to the accompanying drawings.

[0040] A first aspect of this disclosure provides a cleaning brush head, as shown in FIG1, including a floating support 100, a roller brush cover 200, and a foolproof structure 400.

[0041] In some embodiments, as shown in FIG2, the floating support 100 is provided with a receiving groove 101 for accommodating at least one roller brush 300. The roller brush 300 may be constructed as a cylindrical structure, with the side of the cylinder in contact with the cleaning surface for cleaning contaminated areas.

[0042] 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. During the process of connecting the roller brush cover 200 to the floating bracket 100, the foolproof structure 400 can prevent the roller brush cover 200 from being installed backwards or otherwise improperly assembled.

[0043] It should be noted that this disclosure does not specifically limit the number of the receiving grooves 101 and the roller brushes 300. There may be one, two, or more receiving grooves 101. One or two or more roller brushes 300 arranged side by side can be accommodated in one receiving groove 101.

[0044] In some embodiments, the floating bracket 100 may be connected to the roller brush cover 200 to keep the roller brush 300 in the correct installation position. This ensures that the roller brush 300 rotates at high speed within the floating bracket 100 to clean the surface without scratching the surface with the roller brush cover 200.

[0045] In some embodiments, the floating bracket 100 is provided with a snap-fit ​​groove 110. The snap-fit ​​groove 110 is located on the side of the floating bracket 100 facing the roller brush cover 200, and a first snap-fit ​​hook is provided inside the snap-fit ​​groove 110, configured to snap-fit ​​at least a portion of the roller brush cover 200, so that the floating bracket 100 and the roller brush cover 200 are stably connected.

[0046] In some embodiments, multiple snap-fit ​​slots 110 may be provided, and the inlets of multiple snap-fit ​​slots 110 are all facing the side where the roller brush cover 200 is located, configured to connect with the roller brush cover 200. Multiple snap-fit ​​slots 110 can make the connection between the floating bracket 100 and the roller brush cover 200 more stable.

[0047] In some embodiments, the floating support 100 is provided with a front-end retaining groove 120. The front-end retaining groove 120 is located at one end of the floating support 100 and is recessed towards the side away from the roller brush 300. The front-end retaining 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 is abutted and limited against the end of the floating support 100. Further, the roller brush cover 200 is prevented from rotating against one end of the floating support 100 until the roller brush cover 200 is engaged with the floating support 100.

[0048] In some embodiments, the floating support 100 further includes a limiting portion 130, as shown in FIG1, the limiting portion 130 being disposed at the end of the front end claw groove 120 away from the roller brush 300. The thickness direction of the floating support 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 end claw groove 120, so that at least a portion of the roller brush cover 200 engages with the front end claw groove 120, limiting the rotation center and rotation angle of the roller brush cover 200.

[0049] In some embodiments, the roller brush cover 200 is provided with a snap-fit ​​member 210, which matches the snap-fit ​​groove 110 and is adapted to move toward the snap-fit ​​groove 110 under the action of external force and snap into the snap-fit ​​groove 110, thereby realizing a stable connection between the floating bracket 100 and the roller brush cover 200.

[0050] Specifically, the latching member 210 includes a handle, an elastic element, and a second latching hook. The second latching hook has an initial position and a pressed position. When the second latching hook is in the initial position, it latches with the first latching hook; when the second latching hook is in the pressed position, it disengages from the first latching hook.

[0051] The handle and the second latching hook are connected via the elastic element, and are configured such that pressing the handle under external force switches the second latching hook from its initial position to a pressed position.

[0052] When the handle is not subjected to external force, the elastic element is relaxed, and the second locking hook is normally in the initial position; when the handle is subjected to external force, the elastic element is compressed, and the second locking hook switches from the initial position to the pressed position as the external force increases.

[0053] It should be noted separately that the above embodiments are merely exemplary embodiments, and this disclosure does not limit the shape and structure of the snap-fit ​​member 210. The snap-fit ​​member 210 may also be any other structural component having a second snap-fit ​​hook and being able to connect with the first snap-fit ​​hook.

[0054] In some embodiments, multiple snap-fit ​​members 210 may be provided, with each snap-fit ​​member 210 corresponding to a single snap-fit ​​groove 110. The snap-fit ​​members 210 are configured to snap into the snap-fit ​​groove 110 under external force, so as to make the connection between the floating bracket 100 and the roller brush cover 200 more stable.

[0055] 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 being constructed in an "L" shape. The stop portion 230 extends in the thickness direction of the roller brush cover 200, and the front end claw 220 is disposed at one end of the stop portion 230 and configured to be installed within the front end claw groove 120.

[0056] During the installation of the front claw 220 into the front claw groove 120, after the front claw 220 is installed into the front claw groove 120, at least a portion of the stop portion 230 abuts against the limiting portion 130, so that the roller brush cover 200 has a rotation center and rotates stably, configured to connect the roller brush cover 200 to the floating bracket 100.

[0057] Specifically, during the installation of the front-end claw 220 into the front-end claw groove 120, the claw portion first extends into the front-end claw groove 120, causing the stop portion 230 to abut against the limiting portion 130. Further, the brush cover 200 is rotated around the stop position of the stop portion 230 and the limiting portion 130 as the rotation center, causing the brush cover 200 to rotate until the snap-fit ​​member 210 snaps into the snap-fit ​​groove 110, so that the brush cover 200 fits against the floating bracket 100, thereby realizing the connection between the brush cover 200 and the floating bracket 100.

[0058] In some embodiments, a chamfer may be provided on the edge of the front claw 220 opposite to the front claw groove 120, which makes it easier to connect the front claw 220 and the front claw groove 120 and avoids unnecessary mechanical wear when installing or removing the roller brush cover 200. The chamfer helps to avoid the squeezing friction between the sharp corner and the brush plate, reduces the compressive stress on the part, improves the surface quality and prevents the workpiece edge from cracking, improves the toughness of the part and increases the service life of the part.

[0059] In some embodiments, to prevent the roller brush cover 200 from being installed backwards or the roller brush cover 200 from not being properly assembled with the floating bracket 100, which could cause problems such as loud noise from the roller brush 300 during use or even scratching the floor, the cleaning brush head provided in this disclosure also includes a foolproof structure.

[0060] In some embodiments, the foolproof structure 400 includes a foolproof positioning member 410 and a foolproof positioning groove 420. The foolproof positioning member 410 and the foolproof positioning groove 420 are shaped to match, and the foolproof positioning member 410 can be installed inside the foolproof positioning groove 420 so that the foolproof structure 400 can be properly connected.

[0061] Specifically, the foolproof positioning component 410 is detachably connected to the foolproof positioning groove 420. When the foolproof positioning component 410 is connected to the foolproof positioning groove 420, the snap-fit ​​component 210 and the front-end claw 220 are respectively connected to the snap-fit ​​groove 110 and the front-end claw groove 120, and the roller brush cover 200 and the floating bracket 100 will be correctly assembled. If the foolproof positioning component 410 cannot be installed into the foolproof positioning groove 420, the roller brush cover 200 and the floating bracket 100 will not be correctly assembled, and the cleaning brush head will not function properly.

[0062] In some embodiments, the foolproof positioning element 410 is an arc-shaped structural element. Correspondingly, the foolproof positioning groove 420 can be an arc-shaped groove with the same curvature as the foolproof positioning element 410.

[0063] Since the anti-misalignment positioning component 410 and the anti-misalignment positioning groove 420 are arc-shaped structural components and arc-shaped grooves, if the installation direction is opposite during the connection process between the roller brush cover 200 and the floating bracket 100, the two arc-shaped structural components cannot be sleeved, that is, the anti-misalignment positioning component 410 cannot be installed inside the anti-misalignment positioning groove 420. This can effectively avoid the problem of the roller brush cover 200 not being properly assembled with the floating bracket 100 due to the roller brush cover 200 being installed backwards, resulting in the roller brush 300 becoming loose, the working noise being loud, and the roller brush cover 200 scratching the base plate.

[0064] In some embodiments, both the arc-shaped structural member and the arc-shaped groove are circular arcs, and the center of the circular arc is the rotation center of the roller brush cover 200 when it is assembled on the floating bracket 100, that is, the stop position of the stop part 230 and the limiting part 130.

[0065] In response to the insertion of the front claw 220 of the roller brush cover 200 into the front 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 around the stop position, causing the foolproof positioning member 410 to enter the foolproof positioning groove 420 through the inlet. The foolproof positioning member 410 extends along the arc-shaped 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 snap-fit ​​member 210 of the roller brush cover 200 engages with the snap-fit ​​groove 110 of the floating bracket 100, thereby achieving accurate assembly of the roller brush cover 200 and the floating bracket 100.

[0066] 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 large, the curvature of the corresponding foolproof positioning groove 420 will also increase. Furthermore, since the foolproof positioning groove 420 is located outside the foolproof positioning member 410 during assembly, its overall size is slightly larger than that of 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 large space on the cleaning brush head, potentially leading to problems such as increased brush head size and inconvenient connection.

[0067] In some embodiments, when the foolproof positioning member 410 is installed inside the foolproof positioning groove 420, the gap between the foolproof positioning member 410 and the side wall of the foolproof positioning groove 420 does not exceed 1 mm.

[0068] Excessive gap can lead to unstable connection between the brush cover 200 and the floating bracket 100. Furthermore, a large gap between the brush cover 200 and the floating bracket 100 during operation may increase the operating noise of the brush 300.

[0069] If the gap is too small, for example, the gap between the anti-misalignment positioning component 410 and the side wall of the anti-misalignment positioning groove 420 is 0.01mm, then during the installation process, it is easy to encounter problems such as difficulty in alignment or difficulty in moving the anti-misalignment positioning component 410 into the anti-misalignment positioning groove 420.

[0070] In some embodiments, the end of the foolproof positioning member 410 is provided with a first rounded corner or a first chamfer, the first rounded corner or the first chamfer being configured to facilitate insertion into the foolproof positioning groove 420.

[0071] Since the foolproof positioning component 410 needs to be installed into the foolproof positioning groove 420, during the alignment process between the foolproof positioning component 410 and the foolproof positioning groove 420, the end of the foolproof positioning component 410 is easily rubbed against the inlet of the foolproof positioning groove 420 under external force. In mechanical and design fields, sharp corners may cause stress concentration, while rounded corners can disperse forces, reduce wear and damage, extend service life, and reduce damage and maintenance costs. This improves durability and safety.

[0072] In some embodiments, the inlet of the foolproof positioning groove 420 is provided with a second rounded corner or a second oblique angle, which is configured to facilitate the insertion of the foolproof positioning member 410 into the foolproof positioning groove 420.

[0073] The second fillet or the second chamfer can match the shape of the first fillet or the first chamfer of the foolproof positioning component 410, enhancing aesthetics and visual comfort. The corresponding fillet or chamfer setting in the mechanical structure is more in line with engineering principles, guiding the user's eye and making it easier for the user to judge that the first and second fillets are a matching structure, providing a better user experience and a sense of quality.

[0074] In some embodiments, the foolproof structure 400 includes a first foolproof structure and a second foolproof structure, as shown in FIG2, wherein the first foolproof structure and the second foolproof structure are respectively disposed at both ends of the floating bracket 100 and the roller brush cover 200.

[0075] When the front claw 220 of the roller brush cover 200 is inserted into the front 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 around the stop position, causing the foolproof positioning member 410 to enter the foolproof positioning groove 420 through the inlet of the foolproof positioning groove 420.

[0076] The first and second anti-mistake structure's anti-mistake positioning component 410 extends along the arc path inside the anti-mistake positioning groove 420, so that the anti-mistake positioning component 410 is installed inside the anti-mistake positioning groove 420 until the roller brush cover 200 is in contact with the floating bracket 100, so that the snap-fit ​​component 210 of the roller brush cover 200 is snapped into the snap-fit ​​groove 110 of the floating bracket 100, thereby achieving accurate assembly of the roller brush cover 200 and the floating bracket 100.

[0077] During the installation of the roller brush cover 200, the cleaning brush head with a single foolproof structure 400 experiences significant pressure on the foolproof structure 400. Repeated installation and disassembly may increase the gap between the foolproof positioning component 410 and the foolproof positioning groove 420, potentially shortening the service life of the roller brush cover 200. Compared to embodiments with only one foolproof structure 400 in the cleaning brush head, this embodiment provides two foolproof structures 400, which allows for smoother rotation of the roller brush cover 200. The balanced rotational torque on both sides of the roller brush cover 200 prevents excessive pressure on one side of the foolproof structure 400 during rotation.

[0078] In some embodiments, two roller brushes 300 are provided, as shown in FIG2. The two roller brushes 300 are arranged side by side in the receiving groove 101, and the foolproof positioning mechanism is disposed between the two roller brushes 300.

[0079] Specifically, the width direction of the floating support 100 is designated as the second direction, in which two roller brushes 300 are arranged side by side. The foolproof positioning groove 420 can be disposed between the two roller brushes 300, and the foolproof positioning groove 420 does not interfere with the normal rotation of the roller brushes 300.

[0080] The foolproof positioning component 410 can be disposed on the brush cover 200. The foolproof positioning component 410 is directly opposite to the foolproof positioning groove 420 and can be installed into the foolproof positioning groove 420 under the action of external force so that the brush cover 200 and the floating bracket 100 are correctly assembled.

[0081] In some embodiments, as shown in FIG1, the foolproof positioning groove 420 may be disposed on the floating bracket 100; the foolproof positioning member 410 may be disposed on the roller brush cover 200.

[0082] During the connection between the roller brush cover 200 and the floating bracket 100, the front end claw 220 of the roller brush cover 200 is first inserted into the front end claw groove 120, so that the stop portion 230 of the roller brush cover 200 abuts against the limiting portion 130 of the floating bracket 100. Further, the roller brush cover 200 is rotated around the stop position of the stop portion 230 and the limiting portion 130, and the rotation center is the arc center of the foolproof positioning member 410.

[0083] As the roller brush cover 200 rotates around its center, the foolproof positioning member 410 enters the foolproof positioning groove 420 through its inlet. The foolproof positioning member 410 extends along the arc-shaped path inside the foolproof positioning groove 420, allowing it to be installed inside the groove until the roller brush cover 200 and the floating bracket 100 are in contact. This allows the snap-fit ​​member 210 of the roller brush cover 200 to engage with the snap-fit ​​groove 110 of the floating bracket 100, thus achieving accurate assembly of the roller brush cover 200 and the floating bracket 100.

[0084] In some other embodiments, the positions of the foolproof positioning member 410 and the foolproof positioning groove 420 can be interchanged, that is, the foolproof positioning groove 420 is disposed on the roller brush cover 200, and the foolproof positioning member 410 is disposed on the floating bracket 100.

[0085] Similarly, during the connection between the roller brush cover 200 and the floating bracket 100, the front end claw 220 of the roller brush cover 200 is first inserted into the front end claw groove 120, so that the stop portion 230 of the roller brush cover 200 abuts against the limiting portion 130 of the floating bracket 100. Furthermore, the roller brush cover 200 is rotated around the stop position of the stop portion 230 and the limiting portion 130, and the rotation center is the arc center of the foolproof positioning member 410.

[0086] As the roller brush cover 200 rotates around its center, the foolproof positioning member 410 enters the foolproof positioning groove 420 through its inlet. The foolproof positioning member 410 extends along the arc-shaped path inside the foolproof positioning groove 420, allowing it to be installed inside the groove until the roller brush cover 200 and the floating bracket 100 are in contact. This allows the snap-fit ​​member 210 of the roller brush cover 200 to engage with the snap-fit ​​groove 110 of the floating bracket 100, thus achieving accurate assembly of the roller brush cover 200 and the floating bracket 100.

[0087] In some other embodiments, as shown in FIG2, the foolproof positioning member 410 and the foolproof positioning groove 420 can be respectively disposed on both sides of the roller brush 300 on the floating bracket 100. Correspondingly, the roller brush cover 200 is provided with a foolproof positioning groove 420 and a foolproof positioning member 410 corresponding to the foolproof positioning member 410 and the foolproof positioning groove 420.

[0088] Furthermore, the foolproof positioning component 410 is installed inside the foolproof positioning groove 420 until the roller brush cover 200 is in contact with the floating bracket 100, so that the snap-fit ​​component 210 of the roller brush cover 200 is snapped into the snap-fit ​​groove 110 of the floating bracket 100, thereby achieving accurate assembly of the roller brush cover 200 and the floating bracket 100.

[0089] In some embodiments, the foolproof positioning member 410 and the roller brush cover 200 or the floating bracket 100 are separate structures.

[0090] The foolproof positioning component 410 is detachably connected to the brush cover 200 or the floating bracket 100. For example, a first groove is provided at the position where the brush cover 200 connects to the foolproof positioning component 410. Correspondingly, a first slider can be provided on the side of the foolproof positioning component 410 that connects to the brush cover 200. The first slider matches the first groove and is detachably connected to the first groove of the brush cover 200.

[0091] Similarly, the foolproof positioning member 410 is disposed in the same detachable structure of the floating bracket 100 as the above-described detachable connection structure. For example, a second sliding groove is provided at the position where the floating bracket 100 connects with the foolproof positioning member 410. Correspondingly, a second slider can be provided on the side of the foolproof positioning member 410 that connects with the floating bracket 100. The second slider matches the second sliding groove and is detachably connected to the second sliding groove of the floating bracket 100.

[0092] The separate connection between the anti-foolproof positioning component 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 component 410 cannot be installed into the anti-foolproof positioning groove 420, the anti-foolproof positioning component 410 can be disassembled to achieve the fit between the roller brush cover 200 and the floating bracket 100. The cleaning brush head can be assembled by the snap-fit ​​component 210 and the snap-fit ​​groove 110.

[0093] It should be noted separately that the above-mentioned split structure is exemplary, and any other connection structure can be used to achieve the detachable connection between the foolproof positioning component 410 and the roller brush cover 200 or the floating bracket 100, such as magnetic attraction, snap-fit, threaded connection, etc.

[0094] In some embodiments, the foolproof positioning member 410 is an integral structure with the roller brush cover 200 or the floating bracket 100.

[0095] During the production and processing stage, the fact that the foolproof positioning component 410 and the roller brush cover 200 are integrated can reduce the production difficulty during the processing and help improve production efficiency.

[0096] During user application, the integrated structural component offers higher rigidity and compressive strength. When used in scenarios similar to cleaning brush heads, the high-speed rotation of the roller brush 300 during cleaning inevitably causes vibration to the housing. When the foolproof positioning component 410 and the roller brush cover 200 are integrated, it provides excellent shock resistance and durability, preventing damage to the mechanical parts of the foolproof structure from the high-intensity vibrations of the cleaning brush head during operation. The integrated structural component not only offers practicality but also allows for customization using template technology, allowing for different appearances and colors to meet diverse market demands and create more aesthetically pleasing products.

[0097] Similarly, the foolproof positioning component 410 can also be a separate structure or an integral 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 described in detail here.

[0098] In some embodiments, the foolproof positioning element 410 is made of plastic, metal, or alloy.

[0099] Plastics are relatively lightweight materials, a property that makes them suitable for use in the production of products where weight reduction is required. Furthermore, plastics possess excellent chemical stability, good corrosion resistance, superior electrical insulation properties, are poor thermal conductors, and have noise reduction and vibration damping effects.

[0100] In addition, plastics possess high specific strength and a wide distribution of mechanical strength: their hardness, tensile strength, elongation, and impact strength are widely distributed, offering a broad range of application options. Due to their low specific gravity and high strength, plastics exhibit high specific strength.

[0101] The foolproof positioning component 410, supported by metal or alloy materials, has superior mechanical strength, is sturdy, pressure-resistant, interlocking, and weldable, and has excellent moisture resistance and airtightness.

[0102] In other embodiments, the floating support 100 includes a through hole 102 disposed at one end of the front claw groove 120 away from the roller brush 300, configured to allow the front claw groove 120 to communicate with the outside.

[0103] The roller brush cover 200 includes an extension portion disposed at the end of the front end claw 220 away from the latching member 210, extending in a direction away from the latching member 210. Further, after the front end claw 220 is installed into the front end claw groove 120, the end of the front end claw 220 passes through the through hole 102 and extends in a direction away from the roller brush 300. The extension portion is configured such that when the extension portion passes through the through hole 102, the latching member 210 and the front end claw 220 are respectively connected to the latching groove 110 and the front end claw groove 120.

[0104] 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 the installation of the roller brush cover 200 onto the floating bracket 100, the extension portion needs to pass through the through hole 102 so that the front end claw 220 is installed within the front end claw groove 120. In response to the front end claw 220 being installed within the front end claw groove 120, the snap-fit ​​member 210 of the roller brush cover 200 and the snap-fit ​​groove 110 of the floating bracket 100 are in corresponding positions. Under external force, the snap-fit ​​member 210 can engage with the snap-fit ​​groove 110, thereby achieving accurate fit between the roller brush cover 200 and the floating bracket 100.

[0105] Because the extension increases the overall width of the roller brush cover 200, if the extension does not penetrate the through hole 102 or the front claw 220 is not installed in the front claw groove 120, the snap-fit ​​member 210 and the snap-fit ​​groove 110 will be misaligned, that is, the roller brush cover 200 cannot be snapped into the floating bracket 100, thus achieving the foolproof function during the installation of the roller brush cover 200.

[0106] The floating bracket 100 and roller brush cover 200 provided in this embodiment can be used alone in the cleaning brush head to achieve a foolproof effect, or they can work together with the foolproof structure 400 to achieve a foolproof effect during the installation of the cleaning brush head.

[0107] A second aspect of this disclosure provides a cleaning device including the cleaning brush head described in the first aspect of this disclosure.

[0108] After the cleaning brush head is installed in conjunction with the cleaning equipment, the cleaning brush head has a foolproof structure 400. Through the assembly of the foolproof positioning part 410 and the foolproof positioning groove 420 in the foolproof structure 400, the problems of loud working noise of the roller brush 300 and scratching of the cleaning surface by the roller brush cover 200 caused by improper assembly of the floating bracket 100 and the roller brush cover 200 can be effectively avoided, which is conducive to improving the user experience.

[0109] The specific structure, working principle, and beneficial effects of the cleaning brush head and cleaning device provided in this disclosure can be referred to in any of the above embodiments, and will not be repeated here.

[0110] 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. Similar or identical parts between embodiments can be referred to interchangeably. For the systems or apparatus disclosed in the embodiments, since they correspond to the methods disclosed in the embodiments, the descriptions are relatively simple, and relevant parts can be referred to the method section.
