[0037] Exemplary embodiments of the present disclosure are described in detail below in connection with the accompanying figures.

[0038] [Fig.l] shows a schematic view of the structure of a brush head according to some embodiments of the present disclosure; [Fig.2] is a schematic view of a portion of the structure of the brush head of [Fig.l], showing only the brush head housing, the liquid channel plate assembly and the roller brush; [Fig.3] is a schematic view of a portion of the structure of the brush head of [Fig.l] of [Fig.2], showing only the brush head housing and the liquid channel plate assembly; [Fig.4] shows a schematic view of the structure of the liquid channel plate assembly and a squeegee provided by some embodiments of the present disclosure.

[0039] As shown in [Fig.l] to 4, certain embodiments of the present disclosure provide a brush head 100 configured to be assembled to a surface cleaning equipment. The brush head includes a brush head housing 10, a roller brush 20, a liquid channel plate assembly 30, and a squeegee 40.

[0040] The brush head housing 10 has a housing space 11. The roller brush 20 is disposed in the housing space 11 and rotates at high speed to enable the brush head to clean the work surface. The liquid channel plate assembly 30 is disposed between the brush head housing 10 and the roller brush 20. The liquid channel plate assembly 30 is disposed in the housing space 11, assembled to the brush head housing 10 and configured to deliver a cleaning liquid, for example clean water, to the roller brush 20.The surface of the liquid channel plate assembly 30 facing the roller brush 20 is provided with liquid channels that communicate with a clean water tank and liquid spray ports, and the cleaning liquid from the clean water tank flows through the liquid channels in the liquid channel plate assembly 30 and is sprayed from the water spray port to the roller brush 20 to wet the roller brush 20, so that the brush head 100 performs a wet cleaning operation, to realize more efficient cleaning of the working surface.

[0041] When cleaning the working surface by the brush head, the roller brush 20 rotates at a high speed to rub against the working surface to perform cleaning, and the roller brush 20 may be stained with dirt. The squeegee 40 is fixedly connected to the liquid channel plate assembly 30 and configured to lean against the roller brush 20 to clean the dirt on the surface of the roller brush 20. The squeegee 40 leans against the outer surface of the roller brush 20 and, for example, against brush bristles or a brush cloth. The squeegee 40 can scrape the dirt on the surface of the roller brush 20 while the roller brush 20 rotates at a high speed, which ensures a real-time cleaning effect of the squeegee 40 on the roller brush 20.

[0042] The scraper 40 and the liquid channel plate assembly 30 are fixedly connected to each other with their relative positions fixed, and thus can be considered as an integral structure.

[0043] The liquid channel plate assembly 30 is pivotally connected to the brush head housing 10, and the liquid channel plate assembly 30 is configured to have a tendency to rotate relative to the brush head housing 10 so that the squeegee 40 bears against the roller brush 20. The liquid channel plate assembly 30 and the squeegee 40, considered as a set, pivot relative to the brush head housing 10 and have a tendency to rotate relative to the brush head housing 10, so that the squeegee 40 always bears against the roller brush 20, for example, with a predetermined force. The cleaning effect on the surface of the roller brush 20 is therefore ensured.

[0044] According to some embodiments of the present disclosure, by the liquid channel plate assembly being fixedly connected to the squeegee, by the liquid channel plate assembly being pivotally connected to the brush head housing, the liquid channel plate assembly is configured to have a tendency to rotate relative to the brush head housing so that the squeegee bears against the roller brush, thereby facilitating the cleaning of dirt on the surface of the roller brush by the squeegee. Even if the peripheral diameter of the roller brush is worn and reduced after a certain period of use, the squeegee can still bear against the roller brush to clean dirt on the surface of the roller brush.

[0045] [Fig. 5] shows a partial structure of the top view of [Fig. 2]. The brush head housing 10 has an opening 12, at least a portion of the liquid channel plate assembly 30 extends from the opening 12, and the pivoting structure of the brush head housing 10 and the liquid channel plate assembly 30 is disposed at the opening 12. In some embodiments, the brush head 100 further comprises an elastic component 50, which cooperates with the brush head housing 10. brush 10 and the liquid channel plate assembly 30 such that the liquid channel plate assembly 30 tends to rotate relative to the brush head housing 10, and from there, the squeegee 40 always presses against the roller brush 20 to clean the surface of the roller brush 20.

[0046] [Fig. 6] shows a schematic view of the partial sectional structure of [Fig. 2]. As shown in [Fig. 1] to 6, the brush head housing 10 includes a rotating shaft 13. The liquid channel plate assembly 30 is pivotally connected to the brush head housing 10 by means of the rotating shaft 13. The elastic component 50 includes a torsion spring. The torsion spring sleeves the rotating shaft 13, one end of the torsion spring bears on a torsion spring retaining structure on the brush head housing 10 side, and the other end of the torsion spring bears on a torsion spring retaining structure on the liquid channel plate assembly 30 side.The torsion spring is in an energy storage state to enable the liquid channel plate assembly 30 to tend to rotate relative to the brush head housing 10, thereby enabling the squeegee 40 to always abut against the roller brush 20 to clean the surface of the roller brush 20.

[0047] In some embodiments, the squeegee 40 is fixedly connected, for example rigidly, to the liquid channel plate assembly 30 by means of a fastening portion. The fastening portion is for example a bolt, a screw or the like, so that the squeegee 40 is fixedly connected to the liquid channel plate assembly 30, which can improve the rigidity of the squeegee and enable more stable rotational contact between the squeegee 40 and the roller brush 20. In other embodiments, the squeegee 40 and the liquid channel plate assembly 30 may be integrally molded to form a rigid integral structure, so that the rigidity of the squeegee is improved, ensuring good contact between the squeegee and the roller brush.

[0048] In some embodiments, when the surface cleaning equipment is normally operating in the floor cleaning operation, the liquid channel plate assembly 30 tends to rotate relative to the brush head housing 10 in a direction opposite to the rotation direction of the roller brush 20. With this arrangement, the squeegee 40 can better clean the roller brush while the roller brush is cleaning the floor, thereby scraping dirt onto the roller brush 20 with the squeegee 40 when the roller brush 20 is rotating at high speed.

[0049] In some embodiments, the contact angle between the squeegee 40 and the roller brush 20 is from 0 to 90 degrees, for example, 15 degrees, 30 degrees, 45 degrees, 60 degrees, or 75 degrees. In the present disclosure, the contact angle refers to an angle between an extension direction of a free end of the squeegee 40, i.e., say an end that abuts against the roller brush 20, and a diameter of the roller brush passing through an abutment point between the free end of the squeegee 40 and the roller brush. By adopting this angle range, the squeegee 40 can better clean the roller brush, thereby scraping dirt on the roller brush 20 with the squeegee 40 when the roller brush 20 rotates at high speed.

[0050] In some embodiments, as illustrated in Figures 1-6, the brush head 100 has a dual-brush structure, and the housing space 11 of the brush head housing 10 comprises a first housing space 111 and a second housing space 112 arranged side by side.

[0051] The roller brush 20 comprises a first roller brush 21 and a second roller brush 22. The first roller brush 21 is for example a front roller brush, and is therefore also called the front roller brush 21. The second roller brush 22 is for example a rear roller brush, and is therefore also called the rear roller brush 22. The first roller brush 21 and the second roller brush 22 are arranged side by side, and the first roller brush 21 and the second roller brush 22 are arranged in the first housing space 111 and the second housing space 112, respectively. The brush head 100 has a two roller brush structure, and the two roller brushes can rotate in opposite directions to clean the working surface, thereby achieving a better cleaning effect.

[0052] The liquid channel plate assembly 30 comprises a first liquid channel plate assembly 31 and a second liquid channel plate assembly 32, which correspond to the first roller brush 21 and the second roller brush 22, respectively, and are configured to supply the cleaning liquid to the first roller brush 21 and the second roller brush 22, respectively. The liquid channels of the first liquid channel plate assembly 31 and the second liquid channel plate assembly 32 all communicate with the clean water tank.

[0053] The squeegee 40 comprises a first squeegee 41 and a second squeegee 42, which are fixedly connected to the first liquid channel plate assembly 31 and the second liquid channel plate assembly 32, respectively, and which are configured to abut against the first roller brush 21 and the second roller brush 22, respectively. The first squeegee 41 and the second squeegee 42 are respectively fixedly connected to the first liquid channel plate assembly 31 and the second liquid channel plate assembly 32 by means of fastening parts, such as bolts, screws, or the like. By this arrangement, the first squeegee 41 and the first liquid channel plate assembly 31 form an integral structure, which improves the rigidity of the first squeegee 41 and enables more stable contact between the first squeegee 41 and the first roller brush 21. Likewise, the second squeegee 42 and the second liquid channel plate assembly 32 form an integral structure, which enhances the rigidity of the second squeegee 42 and enables more stable contact between the second squeegee 42 and the second roller brush 22.

[0054] In some embodiments, as illustrated in Figures 1-6, a free end of the first squeegee 41 faces the second roller brush 22, and a free end of the second squeegee 42 faces the first roller brush 21.

[0055] In some embodiments, the first roller brush 21 and the second roller brush 22 are configured to rotate in opposite directions. As shown in FIGS. 1-6, the first roller brush and the second roller brush 22 are arranged in parallel and their bristles interfere with each other. When the brush head 100 performs a cleaning operation on a cleaning surface, the first roller brush 21 and the second roller brush 22 rotate in opposite directions. For example, from the perspective of [Fig. 2], the first roller brush 21 rotates counterclockwise and the second roller brush 22 rotates clockwise, so that dirt on the cleaning surface can be collected between the first roller brush 21 and the second roller brush 22 and collected in the wastewater tank via a dirt suction channel.

[0056] The free end of the first squeegee 41 corresponding to the first roller brush 21 faces the second roller brush 22, and the first liquid channel plate assembly 31 fixed as an integral structure with the first squeegee 41 has a tendency to rotate clockwise relative to the brush head housing 10. With this arrangement, the first squeegee 41 can stably press against the first roller brush 21, and as the first roller brush 21 rotates counterclockwise, the first squeegee 41 can scrape the dirt on the surface of the first roller brush 21, ensuring the real-time cleaning effect of the first squeegee 41 on the first roller brush 21.

[0057] The free end of the second squeegee 42 corresponding to the second roller brush 22 faces the second roller brush 22, and the second liquid channel plate assembly 32, fixed as an integral structure with the second squeegee 42, tends to rotate counterclockwise relative to the brush head housing 10. With this arrangement, the second squeegee 42 can stably rest on the second roller brush 22, and as the second roller brush 22 rotates clockwise, the second squeegee 42 can scrape dirt on the surface of the second roller brush 22, ensuring the real-time cleaning effect of the second squeegee 42 on the second roller brush 22.

[0058] In the present disclosure, Figures 5 and 6 only show the pivoting structure of the first liquid channel plate assembly 31 and the brush head housing 10. The brush head housing 10 has an opening 12, at least a portion of the first liquid channel plate assembly 31 extends from the opening 12, and the pivoting structure of the brush head housing 10 and the first liquid channel plate assembly 31 is disposed at the opening 12. The elastic component 50 cooperates with the brush head housing 10 and the first liquid channel plate assembly 31 to enable the first liquid channel plate assembly 30 to have a tendency to rotate relative to the brush head housing 10, which further enables the first squeegee 40 to always be in contact with the first roller brush 21 to clean the surface of the first roller brush 20. The brush head housing 10 brush 10 includes a rotating shaft 13.The first liquid channel plate 30 is pivotally connected to the brush head housing 10 via the rotating shaft. The elastic component 50 comprises a torsion spring. The torsion spring sleeves the rotating shaft 13, one end of the torsion spring bears on a structure retaining the torsion spring on the side of the brush head housing 10, and the other end of the torsion spring bears on a structure retaining the torsion spring on the side of the first liquid channel plate assembly 31. The torsion spring is in an energy storage state to enable the first liquid channel plate assembly 31 to have a tendency to rotate relative to the brush head housing 10, thereby enabling the first squeegee 41 to always abut against the first roller brush 21 to clean the surface of the second roller brush 22.

[0059] The pivoting structure of the second liquid channel plate assembly 32 and the brush head housing 10 is similar to the aforementioned pivoting structure of the first liquid channel plate assembly 31 and the brush head housing 10, and therefore will not be repeated herein.

[0060] In some embodiments, there may be one or more, for example two, pivoting structures of the first liquid channel plate assembly 31 and the brush head housing 10, and the two or more pivoting structures are arranged at intervals in an extension direction of the first liquid channel plate assembly 31.

[0061] In some embodiments, there may be one or more pivoting structures, e.g., two, in the second liquid channel plate assembly 32 and the brush head housing 10, and the two or more pivoting structures are arranged at intervals in an extension direction of the second liquid channel plate assembly 32.

[0062] [Fig.7] shows a schematic view of the structure of surface cleaning equipment provided by certain embodiments of the present disclosure. As shown in [Fig.7], an embodiment of the present disclosure also provides a surface cleaning equipment 1000, comprising a surface cleaning equipment body 200 and the brush head 100, wherein the brush head is configured to removably assemble to the surface cleaning equipment body 200.

[0063] According to the embodiments of the present disclosure, by providing a liquid tank with a filter assembly and a foolproof member that cooperate with each other, the liquid tank can be assembled to the surface cleaning equipment only after the filter assembly has been properly mounted in a mounting groove of the liquid tank, so that dirt in the liquid tank can be prevented from entering the body of the surface cleaning equipment due to careless mounting of the filter assembly by a user, which in turn can prevent the surface cleaning equipment from operating abnormally.

[0064] Finally, it should be noted that the various embodiments described in the description are described in a step-by-step manner, with each embodiment focusing on the differences from other embodiments, and the same or similar parts between the various embodiments may refer to each other.
