Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, and in particular to a floor brush component, cleaning equipment and cleaning system. Background Technology

[0002] Cleaning equipment is a common type of portable household cleaning device. It first appeared in the form of a vacuum cleaner and could only be used in dry environments. In order to meet the needs of use in more environments, especially in wet environments, products such as floor scrubbers have been developed.

[0003] Existing floor scrubbers typically consist of a casing and a rotating brush structure. The rotation of the brush allows for convenient cleaning of the floor. To prevent water stains after cleaning wet surfaces, existing floor scrubbers usually include a squeegee. This squeegee presses against the rotating brush structure, squeezing out excess water as it rotates. This facilitates wastewater collection on the brush and allows for indirect control of the brush's moisture level by adjusting the pressure between the squeegee and the brush, thus preventing excessive water residue.

[0004] Although increasing the pressure of the wiper blades and roller brush structure can solve the problem of excessive water stains, as the roller brush structure wears down during use, the pressure of the wiper blades and roller brush structure will decrease, and the problem of excessive water stains will still exist.

[0021] In some examples of this utility model, the operating component is a foot pedal for the user to step on, and the up-and-down movement of the foot pedal drives the third scraper to move up and down.

[0022] The present invention further proposes a cleaning device comprising the floor brush assembly described in any one of the examples.

[0023] The present invention further proposes a cleaning system, which includes a cleaning device and a base station for charging the cleaning device, wherein the cleaning device is provided with a floor brush assembly as described in any of the above examples.

[0024] In some examples of this utility model, when the floor brush assembly includes only the first roller brush, the base station includes a receiving cavity for accommodating the floor brush assembly and a first air duct outlet for drying the first roller brush.

[0047] The embodiments of this utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. In the following description of the embodiments, "front" refers to the direction in which the cleaning device moves forward, "rear" refers to the direction in which the cleaning device moves backward, and "left and right" refers to the direction in which the roller brush axis extends.

[0048] This utility model proposes a cleaning system, which includes a cleaning device and a base station for charging the cleaning device. The cleaning device is equipped with a floor brush assembly. The floor brush assembly 100 according to an embodiment of this utility model can solve the problem of excessive water stains after wet treatment, improving the user experience. The floor brush assemblies of different embodiments will be described below with reference to the accompanying drawings.

[0049] According to a first aspect embodiment of the present invention, the floor brush assembly mainly protects a scheme having a roller brush and a scraper having a front end of the roller brush that contacts the surface to be cleaned. The floor brush assembly of the first aspect embodiment will be described below with reference to the accompanying drawings.

[0050] like Figures 1 to 3As shown, the floor brush assembly 100 of the first aspect embodiment is used to contact the surface 200 to be cleaned. The floor brush assembly 100 includes a housing 10, a first roller brush 20, and a scraper assembly. The first roller brush 20 is rotatably disposed in the housing 10. The scraper assembly includes a first scraper 30, which includes a positioning end 31 and a cantilever end 32. The positioning end 31 is fixedly disposed on the front side of the first roller brush 20, and the cantilever end 32 contacts the surface 200 to be cleaned in its natural state. The first scraper 30 is made of soft material. When the cleaning device moves forward, the first scraper 30 deforms backward, and dust can enter the floor brush assembly 100 through the gap between the first scraper 30 and the surface 200 to be cleaned under negative pressure. When the cleaning device moves backward, the first scraper 30 deforms forward. At this time, the first scraper 30 contacts the surface 200 to be cleaned, which can help scrape away water stains from mopping and reduce water residue.

[0051] To further improve the cleaning effect, especially the cleaning effect on large debris, a plurality of first protrusions 33 are provided at intervals facing the forward direction above the cantilever end 32 near the surface 200 to be cleaned. These first protrusions 33 are located on the forward-facing side of the first scraper 30. The floor brush assembly 100 has a forward first state and a backward second state, such as... Figure 4 and Figure 5 As shown, in the first state, at least a portion of the first protrusion 33 contacts the surface 200 to be cleaned, and a channel for waste to pass through is formed between two adjacent first protrusions 33. Figure 6 As shown, in the second state, the first scraper 30 contacts the surface 200 to be cleaned. By providing the first protrusion 33, a channel for large debris to pass through can be formed when the floor brush assembly 100 moves forward, improving the pickup effect of large debris and increasing the cleaning efficiency of the cleaning equipment.

[0052] like Figure 1 and Figure 2 As shown, the first scraper 30 is provided with an air passage 40, which facilitates the passage of airflow into the first roller brush 20. Current cleaning equipment typically includes a drying function. When the outlet for the drying airflow is located in front of the roller brush, the air passage 40, situated on the front of the first scraper 30, allows the drying airflow to be easily transmitted to the first roller brush 20 without affecting its drying process.

[0053] Of course, in other embodiments, such as Figure 7 and Figure 8 As shown, the housing 10 includes a first shielding portion 11 located at the front and surrounding at least a portion of the first roller brush 20. A first scraper 30 extends beyond the first shielding portion 11. The first shielding portion 11 is provided with an air passage portion 40, which facilitates the passage of airflow into the first roller brush 20. This design can also deliver hot airflow for drying to the first roller brush 20.

[0054] In one embodiment, regardless of the location of the air passage 40, the air passage 40 can be a plurality of spaced-apart through holes or elongated extension slots. The drying airflow is not a high-velocity airflow. While solving the problem of excessive water stains, based on the position of the first scraper 30, the arrangement of these plurality of through holes or elongated extension slots can achieve drying of the first roller brush 20 while ensuring negative pressure throughout the vacuum cleaner.

[0055] In one embodiment, the first scraper 30 can also undergo vertical displacement. For example... Figures 9 to 12 As shown, the floor brush assembly 100 includes a position adjustment mechanism 50, which is used to adjust the vertical displacement of the first scraper 30. The position adjustment mechanism 50 includes a groove 51 and a sliding part (not shown) that can move within the groove 51. The relative movement of the sliding part and the groove 51 causes the first scraper 30 to move vertically.

[0056] In one embodiment, such as Figure 11 As shown, the position adjustment mechanism 50 includes an operating component 52. The first scraper 30 has a groove 51, and the operating component 52 has a sliding portion. Alternatively, the configuration can be reversed, with the first scraper 30 having a sliding portion and the operating component 52 having a groove. In this embodiment, the operating component 52 moves in a left-right direction parallel to the axis of the first roller brush 20, and this left-right movement drives the first scraper 30 to move up and down. In this embodiment, the user can manually operate the operating component 52 to raise the first scraper 30.

[0057] To facilitate the left-right movement of the operating component 52 to drive the first scraper 30 up-down movement, the groove 51 extends vertically upwards. With this configuration, when the sliding part moves within the groove 51, since the sliding part only has left-right displacement and no up-down displacement, the first scraper 30 will passively move up-down, thereby achieving the effect of the first scraper 30 rising. This provides more space between the first scraper 30 and the surface 200 to be cleaned, allowing large debris to pass through more smoothly.

[0058] like Figures 13 to 15As shown, in another embodiment, the user can also adjust the position without manual operation by using a foot pedal. A foot pedal can be provided on the housing for the user to step on, and the up-and-down movement of the foot pedal drives the first scraper 30 to move up and down. Specifically, the position adjustment mechanism includes an operating component 60 (i.e., a foot pedal) and a transmission component 61. The transmission component 61 is connected to the first scraper 30. The first scraper 30 has a groove 51 as described in the above embodiment, and the transmission component 61 has a sliding portion; or the first scraper 30 has a sliding portion, and the transmission component has a groove. Since the foot-operated operating component 60 is generally positioned further back, the transmission component needs to transmit force from the side of the floor brush assembly to the first scraper 30 to achieve the lifting of the first scraper 30.

[0059] According to a second aspect embodiment of the present invention, the floor brush assembly mainly protects a design having a roller brush, a scraper blade in front of the roller brush that contacts the surface to be cleaned, and the scraper blade having a first protrusion. Compared to the first aspect embodiment, this embodiment does not limit whether the scraper blade is fixed or rotatable; the scraper blade can be a fixed scraper blade or a scraper blade with a rotating shaft. The floor brush assembly of the second aspect embodiment will now be described with reference to the accompanying drawings.

[0060] The structure of the floor brush assembly in the second aspect embodiment can be the same as that in the first aspect embodiment. Therefore, the accompanying drawings adopt the drawings of the floor brush assembly in the first aspect embodiment, and the reference numerals of the relevant components are completely consistent. The beneficial effects of the relevant structural design are also completely the same as those of the floor brush assembly in the first aspect embodiment. In this embodiment, the effects of each technical solution will not be repeated.

[0061] like Figure 1 As shown, the floor brush assembly 100 of the second aspect embodiment is used to contact the surface to be cleaned. The floor brush assembly 100 includes: a housing 10; a first roller brush 20, which is rotatably disposed in the housing 10; and a scraper assembly, which includes a first scraper 30 disposed in front of the first roller brush 20. The first scraper 30 contacts the surface to be cleaned 200 in its natural state. The first scraper 30 has a plurality of spaced first protrusions 33 near the surface to be cleaned, and the plurality of first protrusions 33 are disposed on the side of the first scraper 30 facing forward. The floor brush assembly 100 has a first forward state and a second backward state, as shown in the figure. Figure 4 and Figure 5 As shown, in the first state, at least a portion of the first protrusion 33 contacts the surface 200 to be cleaned, and a channel for waste to pass through is formed between two adjacent first protrusions 33. Figure 6As shown, in the second state, the first scraper 30 contacts the surface 200 to be cleaned. By providing the first protrusion 33, a channel for large debris to pass through can be formed when the floor brush assembly 100 moves forward, improving the pickup effect of large debris and increasing the cleaning efficiency of the cleaning equipment.

[0062] In one embodiment, the first scraper 30 includes a cantilever end that contacts the surface to be cleaned in its natural state, and a plurality of first protrusions 33 that do not contact the surface to be cleaned in their natural state.

[0063] like Figure 2 , Figure 7 and Figure 8 As shown, in one embodiment, the housing 10 includes a first shielding portion 11 located at the front and surrounding at least a portion of the first roller brush 20. A first scraper 30 extends beyond the first shielding portion 11. An air passage portion 40 is provided on the first scraper 30 or the first shielding portion 11 to facilitate airflow passage and entry into the first roller brush. Current cleaning equipment all have a drying function. When the outlet of the drying airflow is located in front of the roller brush, since it is located on the first scraper 30 at the front, the air passage portion 40 facilitates the transmission of the drying airflow to the position of the first roller brush 20 without affecting the drying of the first roller brush 20.

[0064] In one embodiment, regardless of the location of the air passage 40, the air passage 40 can be a plurality of spaced-apart through holes or elongated extension slots. The drying airflow is not a high-velocity airflow. While solving the problem of excessive water stains, based on the position of the first scraper 30, the arrangement of these plurality of through holes or elongated extension slots can achieve drying of the first roller brush 20 while ensuring negative pressure throughout the vacuum cleaner.

[0065] In one embodiment, the first scraper 30 can also undergo vertical displacement. For example... Figures 9 to 12 As shown, the floor brush assembly 100 includes a position adjustment mechanism 50, which is used to adjust the vertical displacement of the first scraper 30. The position adjustment mechanism 50 includes a groove 51 and a sliding part (not shown) that can move within the groove 51. The relative movement of the sliding part and the groove 51 causes the first scraper 30 to move vertically.

[0066] In one embodiment, such as Figure 11As shown, the position adjustment mechanism 50 includes an operating component 52. The first scraper 30 has a groove 51, and the operating component 52 has a sliding portion. Alternatively, the configuration can be reversed, with the first scraper 30 having a sliding portion and the operating component 52 having a groove. In this embodiment, the operating component 52 moves in a left-right direction parallel to the axis of the first roller brush 20, and this left-right movement drives the first scraper 30 to move up and down. In this embodiment, the user can manually operate the operating component 52 to raise the first scraper 30.

[0067] To facilitate the left-right movement of the operating component 52 to drive the first scraper 30 up-down movement, the groove 51 extends vertically upwards. With this configuration, when the sliding part moves within the groove 51, since the sliding part only has left-right displacement and no up-down displacement, the first scraper 30 will passively move up-down, thereby achieving the effect of the first scraper 30 rising. This provides more space between the first scraper 30 and the surface 200 to be cleaned, allowing large debris to pass through more smoothly.

[0068] like Figures 13 to 15 As shown, in another embodiment, the user can also adjust the position without manual operation by using a foot pedal. A foot pedal can be provided on the housing for the user to step on, and the up-and-down movement of the foot pedal drives the first scraper 30 to move up and down. Specifically, the position adjustment mechanism includes an operating component 60 (i.e., a foot pedal) and a transmission component 61. The transmission component 61 is connected to the first scraper 30. The first scraper 30 has a groove 51 as described in the above embodiment, and the transmission component 61 has a sliding portion; or the first scraper 30 has a sliding portion, and the transmission component has a groove. Since the foot-operated operating component 60 is generally positioned further back, the transmission component needs to transmit force from the side of the floor brush assembly to the first scraper 30 to achieve the lifting of the first scraper 30.

[0069] According to a third aspect embodiment of the present invention, the floor brush assembly mainly protects a roller brush, a scraper blade in front of the roller brush that contacts the surface to be cleaned, and air vents on the scraper blade or housing for drying with hot air. This embodiment is the same as the floor brush assembly of the second aspect embodiment, and does not limit whether the scraper blade is fixed or rotatable; the scraper blade can be a fixed scraper blade or a scraper blade with a rotating shaft. The floor brush assembly of the second aspect embodiment will now be described with reference to the accompanying drawings.

[0070] The structure of the floor brush assembly in the third aspect embodiment can be the same as that in the first aspect embodiment. Therefore, the accompanying drawings adopt the drawings of the floor brush assembly in the first aspect embodiment, and the reference numerals of the relevant components are completely consistent. The beneficial effects of the relevant structural design are also completely the same as those of the floor brush assembly in the first aspect embodiment. In this embodiment, the effects of each technical solution will not be repeated.

[0071] like Figure 1 , Figure 2 , Figure 7 As shown in the third aspect embodiment, the floor brush assembly 100 is used to contact the surface to be cleaned. The floor brush assembly includes: a housing 10; a first roller brush 20, which is rotatably disposed on the housing 10; and a scraper assembly, which includes a first scraper 30 disposed on the front side of the first roller brush 20. The first scraper 30 contacts the surface to be cleaned 200 in its natural state. An air passage 40 is provided on the first scraper 30 or on the housing 10 to facilitate airflow through and into the first roller brush. This design can also transfer hot airflow for drying to the first roller brush 20.

[0072] The housing 10 includes a first shielding portion 11 located at the front and surrounding at least part of the first roller brush 20, a first scraper 30 extending beyond the first shielding portion 11, and an air passage portion 40 disposed on the first shielding portion 11.

[0073] In one embodiment, regardless of the location of the air passage 40, the air passage 40 can be a plurality of spaced-apart through holes or elongated extension slots. The drying airflow is not a high-velocity airflow. While solving the problem of excessive water stains, based on the position of the first scraper 30, the arrangement of these plurality of through holes or elongated extension slots can achieve drying of the first roller brush 20 while ensuring negative pressure throughout the vacuum cleaner.

[0074] In one embodiment, the first scraper 30 has a plurality of spaced-apart first protrusions 33 facing the forward direction near the surface 200 to be cleaned, and the plurality of first protrusions 33 are disposed on the forward-facing side of the first scraper 30. The floor brush assembly 100 has a forward first state and a backward second state, such as... Figure 4 and Figure 5 As shown, in the first state, at least a portion of the first protrusion 33 contacts the surface 200 to be cleaned, and a channel for waste to pass through is formed between two adjacent first protrusions 33. Figure 6 As shown, in the second state, the first scraper 30 contacts the surface 200 to be cleaned. By providing the first protrusion 33, a channel for large debris to pass through can be formed when the floor brush assembly 100 moves forward, improving the pickup effect of large debris and increasing the cleaning efficiency of the cleaning equipment.

[0075] In one embodiment, the first scraper 30 can also undergo vertical displacement. For example... Figures 9 to 12As shown, the floor brush assembly 100 includes a position adjustment mechanism 50, which is used to adjust the vertical displacement of the first scraper 30. The position adjustment mechanism 50 includes a groove 51 and a sliding part (not shown) that can move within the groove 51. The relative movement of the sliding part and the groove 51 causes the first scraper 30 to move vertically.

[0076] In one embodiment, such as Figure 11 As shown, the position adjustment mechanism 50 includes an operating component 52. The first scraper 30 has a groove 51, and the operating component 52 has a sliding portion. Alternatively, the configuration can be reversed, with the first scraper 30 having a sliding portion and the operating component 52 having a groove. In this embodiment, the operating component 52 moves in a left-right direction parallel to the axis of the first roller brush 20, and this left-right movement drives the first scraper 30 to move up and down. In this embodiment, the user can manually operate the operating component 52 to raise the first scraper 30.

[0077] To facilitate the left-right movement of the operating component 52 to drive the first scraper 30 up-down movement, the groove 51 extends vertically upwards. With this configuration, when the sliding part moves within the groove 51, since the sliding part only has left-right displacement and no up-down displacement, the first scraper 30 will passively move up-down, thereby achieving the effect of the first scraper 30 rising. This provides more space between the first scraper 30 and the surface 200 to be cleaned, allowing large debris to pass through more smoothly.

[0078] like Figures 13 to 15 As shown, in another embodiment, the user can also adjust the position without manual operation by using a foot pedal. A foot pedal can be provided on the housing for the user to step on, and the up-and-down movement of the foot pedal drives the first scraper 30 to move up and down. Specifically, the position adjustment mechanism includes an operating component 60 (i.e., a foot pedal) and a transmission component 61. The transmission component 61 is connected to the first scraper 30. The first scraper 30 has a groove 51 as described in the above embodiment, and the transmission component 61 has a sliding portion; or the first scraper 30 has a sliding portion, and the transmission component has a groove. Since the foot-operated operating component 60 is generally positioned further back, the transmission component needs to transmit force from the side of the floor brush assembly to the first scraper 30 to achieve the lifting of the first scraper 30.

[0079] According to a fourth aspect embodiment of the present invention, the floor brush assembly mainly protects a roller brush, a scraper blade in front of the roller brush that contacts the surface to be cleaned, and an adjustment mechanism for displacing the scraper blade in the vertical direction. Compared to the first aspect embodiment, this embodiment does not limit whether the scraper blade is fixed or rotatable; the scraper blade can be a fixed scraper blade or a scraper blade with a rotating shaft. The floor brush assembly of a second aspect embodiment will now be described with reference to the accompanying drawings.

[0080] The structure of the floor brush assembly in the fourth embodiment can be the same as that in the first embodiment. Therefore, the accompanying drawings are the same as those of the floor brush assembly in the first embodiment. The reference numerals of the relevant components are also completely identical. The beneficial effects of the relevant structural design are also completely the same as those of the floor brush assembly in the first embodiment. In this embodiment, the effects of each technical solution will not be repeated.

[0081] like Figure 1 , Figure 2 and Figure 5 As shown, the floor brush assembly 100 of the fourth aspect embodiment is used to contact the surface 200 to be cleaned. The floor brush assembly 100 includes: a housing 10; a first roller brush 20, which is rotatably disposed in the housing 10; a scraper assembly, which includes a first scraper 30, which is disposed in front of the first roller brush 20 and contacts the surface 200 to be cleaned in its natural state; and a position adjustment mechanism 50, which is used to adjust the displacement of the first scraper 30 in the vertical direction.

[0082] In one embodiment, such as Figure 11 As shown, the position adjustment mechanism 50 includes an operating component 52. The first scraper 30 has a groove 51, and the operating component 52 has a sliding portion. Alternatively, the configuration can be reversed, with the first scraper 30 having a sliding portion and the operating component 52 having a groove. In this embodiment, the operating component 52 moves in a left-right direction parallel to the axis of the first roller brush 20, and this left-right movement drives the first scraper 30 to move up and down. In this embodiment, the user can manually operate the operating component 52 to raise the first scraper 30.

[0083] To facilitate the left-right movement of the operating component 52 to drive the first scraper 30 up-down movement, the groove 51 extends vertically upwards. With this configuration, when the sliding part moves within the groove 51, since the sliding part only has left-right displacement and no up-down displacement, the first scraper 30 will passively move up-down, thereby achieving the effect of the first scraper 30 rising. This provides more space between the first scraper 30 and the surface 200 to be cleaned, allowing large debris to pass through more smoothly.

[0084] like Figures 13 to 15As shown, in another embodiment, the user can also adjust the position without manual operation by using a foot pedal. A foot pedal can be provided on the housing for the user to step on, and the up-and-down movement of the foot pedal drives the first scraper 30 to move up and down. Specifically, the position adjustment mechanism includes an operating component 60 (i.e., a foot pedal) and a transmission component 61. The transmission component 61 is connected to the first scraper 30. The first scraper 30 has a groove 51 as described in the above embodiment, and the transmission component 61 has a sliding portion; or the first scraper 30 has a sliding portion, and the transmission component has a groove. Since the foot-operated operating component 60 is generally positioned further back, the transmission component needs to transmit force from the side of the floor brush assembly to the first scraper 30 to achieve the lifting of the first scraper 30.

[0085] In one embodiment, the first scraper 30 has a plurality of spaced protrusions 33 facing the forward direction near the surface 200 to be cleaned, and the plurality of protrusions 33 are disposed on the forward-facing side of the first scraper 30. The floor brush assembly 100 has a first forward state and a second backward state, such as... Figure 4 and Figure 5 As shown, in the first state, at least a portion of the first protrusion 33 contacts the surface 200 to be cleaned, and a channel for waste to pass through is formed between two adjacent first protrusions 33. Figure 6 As shown, in the second state, the first scraper 30 contacts the surface 200 to be cleaned. By providing the first protrusion 33, a channel for large debris to pass through can be formed when the floor brush assembly 100 moves forward, improving the pickup effect of large debris and increasing the cleaning efficiency of the cleaning equipment.

[0086] like Figure 1 and Figure 2 As shown, the first scraper 30 is provided with an air passage 40, which facilitates the passage of airflow into the first roller brush 20. Current cleaning equipment typically includes a drying function. When the outlet for the drying airflow is located in front of the roller brush, the air passage 40, situated on the front of the first scraper 30, allows the drying airflow to be easily transmitted to the first roller brush 20 without affecting its drying process.

[0087] like Figure 7 and Figure 8 As shown, in one embodiment, the housing 10 includes a first shielding portion 11 located at the front and surrounding at least a portion of the first roller brush 20. A first scraper 30 extends beyond the first shielding portion 11, and an air passage portion 40 is provided on the first scraper 30 or the first shielding portion 11 to facilitate airflow through and into the first roller brush. This design can also deliver hot airflow for drying the first roller brush 20.

[0088] In one embodiment, regardless of the location of the air passage 40, the air passage 40 can be a plurality of spaced-apart through holes or elongated extension slots. The drying airflow is not a high-velocity airflow. While solving the problem of excessive water stains, based on the position of the first scraper 30, the arrangement of these plurality of through holes or elongated extension slots can achieve drying of the first roller brush 20 while ensuring negative pressure throughout the vacuum cleaner.

[0089] like Figure 16 As shown, the floor brush assembly according to the fifth aspect embodiment of the present invention differs from the floor brush assemblies of the first to fourth aspects embodiments in that the floor brush assembly of the fifth aspect embodiment further includes a second scraper 70 in addition to the floor brush assemblies of the first to fourth aspects embodiments. The first scraper 30 is disposed on the front side of the first roller brush 20, and the second scraper 70 is disposed on the rear side of the first roller brush 20. The first scraper 30 and the second scraper 70 contact the surface to be cleaned in their natural state. Since other technical features of the floor brush assembly of the fifth aspect embodiment are the same as those of the floor brush assemblies of the first to fourth aspects embodiments, other identical structures of the floor brush assemblies of the first to fourth aspects embodiments will not be repeated.

[0090] like Figure 17 As shown, the floor brush assembly according to the sixth aspect embodiment of the present invention differs from the floor brush assemblies of the first to fifth aspects embodiments in that the floor brush assembly of the sixth aspect embodiment further includes a second roller brush 80, i.e., a double roller brush design. The second roller brush 80 is located behind the first roller brush 20 and is rotatably disposed in the housing 10, with the first roller brush 20 and the second roller brush 80 spaced apart. Since other technical features of the floor brush assembly of the sixth aspect embodiment are the same as those of the floor brush assemblies of the first to fifth aspects embodiments, other identical structures of the floor brush assemblies of the first to fifth aspects embodiments will not be repeated.

[0091] In addition to the dual-roller brush structure design, one embodiment of the floor brush assembly in the sixth aspect embodiment only has a first scraper 30.

[0092] In addition to the dual-roller brush structure, the floor brush assembly of the sixth aspect embodiment also has two scraper strips in another embodiment, namely a first scraper strip 30 and a second scraper strip 70.

[0093] In other embodiments, the first scraper 30 and the second scraper 70 can be disposed on the second roller brush 80. Specifically, the scraper assembly includes a third scraper, which is disposed on the rear side of the second roller brush and contacts the surface to be cleaned in its natural state. The third scraper has a plurality of spaced second protrusions facing the rearward direction near the surface to be cleaned, with the second protrusions positioned on the rearward side of the third scraper. The floor brush assembly has a forward first state and a backward second state. In the first state, the third scraper contacts the surface to be cleaned; in the second state, at least a portion of the second protrusions contacts the surface to be cleaned, forming a channel between adjacent second protrusions for debris to pass through. The housing includes a second shielding portion located at the rear, surrounding at least a portion of the second roller brush. The third scraper extends beyond the second shielding portion, and an air passage is provided on the third scraper or the second shielding portion to facilitate airflow through and into the second roller brush. The air passage is a plurality of spaced-apart through holes or elongated extension slots. The floor brush assembly includes a position adjustment mechanism for adjusting the vertical displacement of the third scraper. The position adjustment mechanism includes a groove and a sliding part that can move within the groove. The relative movement of the sliding part and the groove causes the third scraper to move vertically. The position adjustment mechanism also includes an operating component. The third scraper has a groove, and the operating component has a sliding part; or the third scraper has a sliding part, and the operating component has a groove. The operating component moves horizontally parallel to the axis of the first roller brush, and this horizontal movement causes the third scraper to move vertically. The groove extends vertically upwards at an angle. The position adjustment mechanism also includes an operating component and a transmission component. The transmission component is connected to the third scraper. The third scraper has a groove, and the transmission component has a sliding part; or the third scraper has a sliding part, and the transmission component has a groove. The operating component is a foot pedal for the user to step on. The vertical movement of the foot pedal causes the third scraper to move vertically.
