[0019] The following detailed description of example implementations refers to the accompanying drawings. The same reference numbers in different drawings may identify the same or similar elements.

[0020] Household surface cleaning devices are suitable for cleaning floor surfaces. Certain types of household surface cleaning devices include a fluid delivery system that delivers a cleaning fluid to a surface to be cleaned, and a fluid recovery system that extracts spent cleaning fluid and debris from the surface. The fluid delivery system typically includes one or more fluid supply tanks for storing a supply of cleaning fluid, a fluid dispenser for applying the cleaning fluid to the surface to be cleaned, and a fluid supply conduit for delivering the cleaning fluid from the fluid supply tank to the fluid dispenser. Household surface cleaning devices typically provide an agitator for agitating the cleaning fluid on the surface. The fluid recovery system typically includes a recovery tank, a nozzle adjacent to the surface to be cleaned and in fluid communication with the recovery tank through a working air conduit, and a fluid suction source in communication with the working air conduit to draw the cleaning fluid from the surface to be cleaned and through the nozzle and the working air conduit to the recovery tank.

[0021] The stirring member of the surface cleaning device may include a housing and a cover body of the surface cleaning device that can rotate in a receiving space formed by the housing and the cover body of the surface cleaning device. The surface cleaning device is provided with a scraper configuration in the above-mentioned receiving space, which helps to evenly distribute the cleaning liquid along the length of the stirrer and eliminate excess liquid and hair on the stirrer to prevent streaks on the surface and prevent hair from being entangled on the stirrer. However, after the fluff on the surface of the stirring member of the prior art is scraped off by the scraper during the rotation process, it is not easy to be sucked into the suction channel for recovery due to the turbulence disturbance of the suction airflow.

[0022] The embodiments of the utility model improve the cleaning efficiency and the hair removal effect on the stirring element by designing the interference degree of the scraper relative to the suction opening, while reducing the marks left on the floor surface after the cleaning operation, thereby making the cleaned floor safer and more beautiful based on the efficient cleaning of floor stains.

[0023] Figure 1-7 Schematic diagram of an example embodiment of a floor brush related to the present disclosure. Figure 1 and 2 As shown, the floor brush 101 may include at least one stirring member 102 to agitate the surface to be cleaned. In one embodiment, the stirring member 102 is a rotating roller brush. The fluid distributor 104 directly delivers the liquid cleaning fluid to the roller brush. In a non-limiting example, the suction port 106 is positioned adjacent to the roller brush to collect liquid and debris directly from the roller brush. In some aspects of the present disclosure, the suction port 106 is substantially distributed along the lateral direction of the roller brush and is fluidly connected to the suction port 108 in a gradually narrowing manner.

[0024] like Figure 2 In some examples of the present disclosure, the floor brush 101 includes a scraping mechanism 100, which is configured to scrape off dirt (such as dirty water and particles) from the surface to be cleaned that is adsorbed on the fluff of the stirring member 102 during the operation of the surface cleaning device, and to remove long hair (usually greater than 20 cm) entangled on the surface of the stirring member 102.

[0025] like Figure 3-5 In some embodiments, the scraping mechanism 100 may include a base 110 and scraping teeth 134 formed on the base 110. In some embodiments, the base 110 may be configured to couple the scraping mechanism 100 to a surface cleaning device near a suction port 106, such as Figure 2 shown.

[0026] In some embodiments, the base 110 can be configured to hold the scraper teeth 134 based on receiving a portion of the scraper teeth 134. For example, Figure 3 and 4As shown, the base 110 and the scraper teeth 134 may be made by integral molding, and may also include an adhesive and / or a coupling device, which is configured to hold the scraper teeth 134 on the base 110. In addition, or alternatively, the base 110 may be configured to form a connecting portion (e.g., a channel) shaped to receive and / or hold the end of the scraper teeth 134.

[0027] like Figure 3 As shown, in some embodiments, the scraping mechanism 100 can include a scraping bar 132 and scraping teeth 134. In some embodiments, the scraping bar 132 is configured to scrape off the waste liquid adhered to the fluff of the stirring member 102, and the scraping teeth 134 are configured to scrape off the hair adhered to the fluff of the stirring member 102.

[0028] In some embodiments, the scraper bar 132 can be separated from the scraper teeth 134. For example, the scraper bar 132 is located above the scraper teeth 134. Figure 5 As shown, the scraper bar 132 may include a straight scraper plate 1321, and a plurality of free ends 1341 of the scraper teeth 134 may be arranged to extend away from the scraper plate 1321. In some embodiments, the scraper teeth 134 may be held near one side of the scraper bar 132. In addition, or alternatively, the scraper teeth 134 may be integrally formed with the scraper bar 132 and connected to the base 110 together, for example, by using an adhesive and / or a coupling device to achieve the connection.

[0029] In some embodiments, a plurality of scraper bars 132 may be included. For example, the scraper teeth 134 may include two scraper bars 132. The scraper teeth 134 may be adjacent to and / or connected to one or more of the plurality of scraper bars 135. For example, the base 110 may retain the scraper teeth 134 near the two scraper bars 132 (e.g., the scraper teeth 134 may be positioned between one scraper bar and another scraper bar).

[0030] In some embodiments, the base 110 may be configured to enable the scraper bar 132 to extend through a first portion of the pile of the agitator 102 while enabling the scraper teeth 134 to extend through a second portion of the pile of the agitator 102 .

[0031] In some embodiments, Figure 2 Combined with Figure 5 and Figure 7As shown, the free ends 1341 of the plurality of scraping teeth 134 extend downward relative to the base 110, and when the base 110 is coupled to the floor brush 101, the plurality of free ends 1341 extending downward obliquely are configured to be located within the projection range of the suction port 106. During the operation of the floor brush 101, as the stirring member 102 rotates, the scraping teeth 134 interfering with the stirring member 102 scrape the hair off the roller brush. Since the free ends 1341 are within the projection range of the suction port 106, that is, a portion of the scraping teeth 134 is located in the suction duct of the surface cleaning device, the vacuum airflow will form a smooth transition at the interference portion between the scraping teeth 134 and the stirring member 102 to avoid the generation of turbulence.

[0032] The scraping teeth have a tooth tip portion, and the action portion and the connection portion are connected to each other via the tooth tip portion of the scraping teeth.

[0033] With such an arrangement, the hair scraped off from the surface of the stirring member 102 can be sucked into the suction air duct in a smoother manner, and finally collected in the recovery tank of the surface cleaning device.

[0034] In one example, in order to ensure that the shaved hair smoothly transitions to the suction duct, when the scraping assembly is installed near the stirring member 102, the bottom surface 112 of the base of the scraping mechanism and the upper surface of the suction port 106 are located in the same plane, or the bottom surface 112 of the base is slightly lower than the upper surface of the suction port 106. Through the above arrangement, the vacuum airflow can smoothly transition between the bottom surface 112 of the base and the upper surface of the suction port 106, and no structure that hinders the advancement of the vacuum airflow will be formed.

[0035] In one example, if Figure 4 and Figure 5 The bottom surface 112 of the base has a transversely extending length, which is set to be substantially consistent with the transverse length of the suction port 106. When the base is installed near the stirring member 102 or the suction port 106, it can be ensured that there is no gap between the bottom surface 112 of the base and the suction port 106 to prevent the generation of turbulence.

[0036] In some examples, the extended free end 1341 is arranged downward and outward relative to the bottom surface 112 of the base, and at least a portion of the free end 1341 of the scraper tooth should extend below the bottom surface 112 of the base. When the bottom surface 112 of the base is installed in place (located on the upper surface of the suction port 106 or slightly below the upper surface of the suction port 106), the free end 1341 can be located within the projection range of the suction port 106.

[0037] In some embodiments, Figure 7As shown, the free end 1341 can be configured to scrape off the long hair wrapped around the stirring member 102 and introduce it into the suction port 106 on the floor brush 101. For example, the free end 1341 may include a planar action surface 140 and at least one curved action surface 142, and the planar action surface 140 and the at least one curved action surface 142 are connected to each other through the at least one first action portion 144. In some embodiments, the first action portion 144 may be a portion including a tooth tip 170 that directly acts on the hair adsorbed on the fluff of the stirring member 102, and can absorb hair within a specific length range (for example, from about 10 cm to about 40 cm). The first action portion 144 may include a transitional curved surface to prevent an overly sharp action surface from causing damage to the fluff of the stirring member 102.

[0038] In some embodiments, Figure 7 As shown, the curved surface action surface 142 includes a first guide curved surface 146 and a second guide curved surface 148. For example, the first guide curved surface 146 and the second guide curved surface 148 are both streamlined curved surfaces. The first guide curved surface 146 and the second guide curved surface 148 are respectively located on both sides of the free end 1341. The first guide curved surface 146 and the second guide curved surface 148 provide convenience for the hair to be guided to both sides of the free end 1341. A guide gap 150 is formed between the guide curved surfaces of the adjacent free ends 1341, and the shaved hair can be guided to the suction port 106 through the gap 150 under the vacuuming action of the surface cleaning device.

[0039] In some embodiments, the first guide curved surface 146 and the second guide curved surface 148 are connected to each other through a connecting portion 160. In some embodiments, the connecting portion 160 has a guiding function and may be a portion including a tooth tip 170 that indirectly acts on the hair adsorbed on the fluff of the stirring member 102, and after the hair is scraped off by the tooth tip 170, it can be diverted through the connecting portion 160 and guided to the gap 150 along the first guide curved surface 146 or the second guide curved surface 148.

[0040] In some embodiments, Figure 5 and 6 As shown, the connecting portion 160 is arranged at an angle α with the bottom surface 112 of the base. In one embodiment, α is less than or equal to 180°. α should generally be set to be significantly less than 180°. For example, in one example, α is not greater than 150°, so that the free end 1341 at the far end of the connecting portion 160 can be lower than the bottom surface 112 of the base, so as to ensure that when the hair is scraped off from the stirring member 102 and passes through the free end 1341, it is just located in the suction air duct, and the scraped hair can be smoothly sucked into the recovery tank.

[0041] Figure 7A floor brush 101 is described, which includes a detachable floor brush cover 111 arranged across the receiving groove of the stirring member 102. Although FIG. 4 depicts a detachable floor brush cover 111, the scraping mechanism disclosed herein can also be used in a surface cleaning device where the floor brush 101 cover is not detachable.

[0042] like Figure 7 As shown, the scraping mechanism 100 can be coupled to the lower edge of the floor brush cover 111, and the lower edge forms the upper periphery of the scraping strip 132. The base 110 can be coupled to the lower edge of the floor brush cover 111 to allow the free end of the scraping teeth to be located within the projection range of the suction port 106 when the floor brush cover 111 is installed on the floor brush 101 and covers the accommodating cavity of the stirring member 102.

[0043] In one embodiment, the scraping teeth 134 can be configured to interfere with the fluff of the stirring member 102 more than the scraping strip 132. That is, the free end 1341 is further away from the scraping strip 132 and closer to the center of the suction duct. Figure 7 When rotating in the first direction A shown, the interference amount of the tooth tip 170 of each free end 1341 of the scraping tooth 134 on the fluff is greater than the interference amount of the scraping plate 1321 of the scraping strip on the fluff. Therefore, the hair will not be pressed by the scraping plate 1321, so that the free end 1341 plays a role in scraping the hair. In order to facilitate scraping and guiding the hair, in one embodiment, when the floor brush cover 111 is installed on the floor brush 101, the lower edge of the connecting portion 160 of the scraping tooth forms an angle of not less than 30° with the horizontal plane.
