[0046] The embodiments of the utility model will be described in detail below, and the embodiments described with reference to the drawings are exemplary. In the following embodiment description, "front" refers to the direction in which the cleaning device advances, "rear" refers to the direction in which the cleaning device retreats, and "left and right" refers to the direction in which the roller brush axis extends.

[0047] The utility model provides a kind of cleaning system, it includes cleaning device and the base station for charging cleaning device. The cleaning device is equipped with floor brush assembly. According to the floor brush assembly 100 of the utility model embodiment, the problem of too much water stain after wet treatment can be solved, and user experience is improved. Different embodiments of floor brush assembly will be described below with reference to the drawings.

[0048] According to the floor brush assembly of the first aspect embodiment of the utility model, the scheme mainly protects that a roller brush has and the roller brush has scraping strip in front and contacts with the surface to be cleaned, and the floor brush assembly of the first aspect embodiment will be described below with reference to the drawings.

[0049] As Figures 1 to 3 As shown in the figure, the floor brush assembly 100 of the first aspect embodiment is used to contact with the surface to be cleaned 200. The floor brush assembly 100 includes a housing 10, a first roller brush 20 and a scraping strip assembly. The first roller brush 20 is rotatably arranged on the housing 10. The scraping strip assembly includes a first scraping strip 30, and the first scraping strip 30 includes a positioning end 31 and a cantilever end 32. The positioning end 31 is fixedly arranged on the front side of the first roller brush 20, and the cantilever end 32 contacts the surface to be cleaned 200 in a natural state. The first scraping strip 30 is made of soft material. When the cleaning device advances, the first scraping strip 30 deforms backward, and dust can enter the inside of the floor brush assembly 100 through the gap between the first scraping strip 30 and the surface to be cleaned 200 under the action of negative pressure. When the cleaning device retreats, the first scraping strip 30 deforms forward, and at this time, the first scraping strip 30 contacts the surface to be cleaned 200 to assist in scraping the water stain on the floor, thereby reducing the residual water stain.

[0050] In order to further improve the cleaning effect, especially the cleaning effect of large garbage, a plurality of first protrusions 33 facing the advancing direction are arranged at the position close to the surface to be cleaned 200 above the cantilever end 32, and the plurality of first protrusions 33 are arranged on the side of the first scraping strip 30 facing the front. Figure 4 Figure 5 ​As shown, in the first state, at least a portion of the first protrusion 33 is in contact with 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.

[0051] 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.

[0052] 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.

[0053] 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.

[0054] 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.

[0055] In one embodiment, such as Figure 11As shown, the position adjusting mechanism 50 comprises an operating assembly 52, the first scraping strip 30 is provided with a groove portion 51, and the operating assembly 52 is provided with a sliding portion. Of course, the reverse arrangement is also possible, that is, the first scraping strip 30 is provided with a sliding portion, and the operating assembly 52 is provided with a groove portion. In this embodiment, the operating assembly 52 moves in the left-right direction parallel to the axis of the first rolling brush 20, and the left-right movement of the operating assembly 52 drives the up-down movement of the first scraping strip 30. In this embodiment, the user can manually dial the operating assembly 52 to operate the lifting of the first scraping strip 30.

[0056] In order to conveniently realize the up-down movement of the first scraping strip 30 driven by the left-right movement of the operating assembly 52, the groove portion 51 extends upwardly in the vertical direction. In this way, when the sliding portion moves in the groove portion 51, the sliding portion only has left-right displacement without up-down displacement, so that the first scraping strip 30 is passively moved in the up-down direction, thereby realizing the lifting effect of the first scraping strip 30, and providing a larger space between the first scraping strip 30 and the surface 200 to be cleaned, so that the large garbage passes more smoothly.

[0057] As shown in FIG. 1, Figures 13 to 15 In another embodiment, the user can also not need to manually dial, but can use the foot stepping mode. A foot pedal for the user to step on can be arranged on the shell, and the up-down movement of the foot pedal drives the up-down movement of the first scraping strip 30. Specifically, the position adjusting mechanism comprises an operating assembly 60 (i.e., the foot pedal) and a transmission assembly 61, the transmission assembly 61 is connected with the first scraping strip 30, the first scraping strip 30 is provided with the groove portion 51 of the above embodiment, and the transmission assembly 61 is provided with the sliding portion; or the first scraping strip 30 is provided with the sliding portion, and the transmission assembly is provided with the groove portion. Since the foot-operated operating assembly 60 is generally arranged more rearwardly, it is necessary to arrange the transmission assembly to transmit the force from the side of the floor brush assembly to the first scraping strip 30, so as to realize the lifting of the first scraping strip 30.

[0058] According to the floor brush assembly of the second aspect embodiment of the present application, the floor brush assembly mainly protects the scheme that the rolling brush has a first protruding portion, the rolling brush has a scraping strip in contact with the surface to be cleaned in the front, and the scraping strip has the first protruding portion. Compared with the first aspect embodiment, this embodiment does not limit whether the scraping strip is fixed or rotatable. The scraping strip can be a fixed scraping strip or a scraping strip with a rotating shaft. The floor brush assembly of the second aspect embodiment will be described below with reference to the accompanying drawings.

[0059] The floor brush assembly structure of the second aspect embodiment can be the same as that of the first aspect embodiment, so the drawings of the first aspect embodiment are adopted, the reference numerals of the related parts are completely consistent, and the beneficial effects of the related structure design are completely the same as those of the first aspect embodiment. In this embodiment, the effects of each technical solution will not be repeated.

[0060] As shown in FIG. 1,Figure 1 As shown, the ground brush assembly 100 of the second aspect embodiment is used to contact the surface to be cleaned, the ground brush assembly 100 comprises: a housing 10; a first roller brush 20 rotatably arranged in the housing 10. A scraping strip assembly, the scraping strip assembly comprises a first scraping strip 30 arranged at the front side of the first roller brush 20, the first scraping strip 30 contacts the surface to be cleaned 200 in a natural state, the first scraping strip 30 is provided with a plurality of first protrusions 33 arranged at intervals near the position close to the surface to be cleaned 200, and the plurality of first protrusions 33 are arranged on the side of the first scraping strip 30 facing the front. The ground brush assembly 100 has a first state of advancing and a second state of retreating, as shown in Figure 4 and Figure 5 In the first state, at least part of the first protrusions 33 are in contact with the surface to be cleaned 200, and a channel for garbage to pass through is formed between adjacent two first protrusions 33. As shown in Figure 6 In the second state, the first scraping strip 30 is in contact with the surface to be cleaned 200. By arranging the first protrusions 33, a channel for large garbage to pass through can be formed when the ground brush assembly 100 advances, thereby improving the pickup effect of large garbage and improving the cleaning efficiency of the cleaning equipment.

[0061] In one embodiment, the first scraping strip 30 comprises a cantilever end, the cantilever end contacts the surface to be cleaned in a natural state, and the plurality of first protrusions 33 do not contact the surface to be cleaned in a natural state.

[0062] As shown in Figure 2 , Figure 7 and Figure 8 In one embodiment, the housing 10 comprises a first shielding portion 11 located in front of the first roller brush 20, the first scraping strip 30 extends beyond the first shielding portion 11, and a wind passing portion 40 is arranged on the first scraping strip 30 or the first shielding portion 11, the wind passing portion is used to facilitate the airflow to pass through and enter the first roller brush. The current cleaning equipment all has a drying function, when the air outlet of the drying airflow is arranged in front of the roller brush, due to the arrangement of the first scraping strip 30 located in front, the wind passing portion 40 can be arranged to facilitate 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.

[0063] In one embodiment, regardless of the position of the wind passing portion 40, the wind passing portion 40 can be a plurality of through holes or long and narrow extension grooves arranged at intervals. The drying airflow is not a high-speed airflow, while solving the problem of too much water stains, based on the position of the first scraping strip 30, the arrangement of the plurality of through holes or long and narrow extension grooves can realize the drying of the first roller brush 20 under the condition of ensuring the negative pressure of the dust collection equipment.

[0064] In one embodiment, the first scraping strip 30 can also displace in the vertical direction. As shown in 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.

[0065] 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.

[0066] 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.

[0067] 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.

[0068] According to the third aspect of the utility model, the ground brush assembly mainly has a rolling brush, the rolling brush has a scraping strip in contact with the surface to be cleaned in the front, and the scraping strip or the shell has a wind passing hole for drying the hot air drying airflow. This embodiment is the same as the ground brush assembly of the second aspect, and does not limit whether the scraping strip is fixed or rotatable. The scraping strip can be a fixed scraping strip or a scraping strip with a rotating shaft. The ground brush assembly of the second aspect will be described below with reference to the drawings.

[0069] The ground brush assembly structure of the third aspect can be the same as that of the first aspect, so the drawings of the first aspect are used, the reference numerals of the related parts are completely consistent, and the beneficial effects of the related structure design are the same as those of the first aspect. The effects of each technical solution are not repeated in this embodiment.

[0070] As shown in Figure 1 , Figure 2 , Figure 7 The ground brush assembly 100 of the third aspect is used to contact the surface to be cleaned. The ground brush assembly includes a shell 10, a first rolling brush 20 rotatably arranged in the shell 10, and a scraping strip assembly including a first scraping strip 30 arranged on the front side of the first rolling brush 20. The first scraping strip 30 contacts the surface to be cleaned 200 in a natural state. A wind passing portion 40 is arranged on the first scraping strip 30 or the shell 10, and is used to facilitate airflow passing through and entering the first rolling brush. The wind passing portion 40 is used to facilitate airflow passing through and entering the first rolling brush 20. This design can also transmit the dried hot air flow to the first rolling brush 20 to dry the first rolling brush 20.

[0071] The shell 10 includes a first shielding portion 11 surrounding at least part of the first rolling brush 20 in the front. The first scraping strip 30 extends beyond the first shielding portion 11, and the wind passing portion 40 is arranged on the first shielding portion 11.

[0072] In one embodiment, regardless of the position of the wind passing portion 40, the wind passing portion 40 can be a plurality of spaced-apart through holes or long and narrow extension grooves. The dried airflow is not a high-speed airflow. While solving the problem of excessive water stains, based on the position of the first scraping strip 30, the arrangement of the plurality of through holes or long and narrow extension grooves can realize the drying of the first rolling brush 20 while ensuring the negative pressure of the dust collection equipment.

[0073] In one embodiment, the first scraping strip 30 has a plurality of first convex portions 33 arranged at intervals and facing the forward direction at a position close to the surface to be cleaned 200. The plurality of first convex portions 33 are arranged on the side of the first scraping strip 30 facing the front. The ground brush assembly 100 has a first advancing state and a second retreating state.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.

[0074] 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.

[0075] 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.

[0076] 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.

[0077] like Figures 13 to 15As shown in one other embodiment, the user can also not need to manually dial, can use the way of stepping on the foot, can set the foot pedal for the user to step on the shell, and the up-down movement of the foot pedal drives the up-down movement of the first scraping strip 30. Specifically, the position adjusting mechanism includes an operating assembly 60 (i.e. the foot pedal) and a transmission assembly 61, the transmission assembly 61 is connected with the first scraping strip 30, the first scraping strip 30 is provided with the groove part 51 of the above embodiment, and the transmission assembly 61 is provided with a sliding part; or the first scraping strip 30 is provided with a sliding part, and the transmission assembly is provided with a groove part. Since the foot pedal type operating assembly 60 is generally set more to the rear, the transmission assembly needs to be set to transmit the force to the first scraping strip 30 from the side of the floor brush assembly to realize the lifting of the first scraping strip 30.

[0078] According to the fourth aspect embodiment of the floor brush assembly of the utility model, the floor brush assembly mainly protects that a rolling brush has a scraping strip in contact with a surface to be cleaned in front and has an adjusting mechanism to displace the scraping strip in the vertical direction. Compared with the first aspect embodiment, this embodiment does not limit whether the scraping strip is fixed or rotatable, and the scraping strip can be a fixed scraping strip or a scraping strip with a rotating shaft. The floor brush assembly of the second aspect embodiment will be described below with reference to the drawings.

[0079] The floor brush assembly structure of the fourth aspect embodiment can be the same as that of the first aspect embodiment, so the drawings adopt the drawings of the floor brush assembly of the first aspect embodiment, the related part numbers are completely consistent, and the beneficial effects of the related structure design are completely the same as those of the floor brush assembly of the first aspect embodiment. In this embodiment, the effects of each technical solution will not be repeated.

[0080] As shown in Figure 1 , Figure 2 and Figure 5 , the fourth aspect embodiment of the floor brush assembly 100 is used to contact the surface to be cleaned 200, and the floor brush assembly 100 includes: a shell 10; a first rolling brush 20, which is rotatably arranged in the shell 10; a scraping strip assembly, which includes a first scraping strip 30, the first scraping strip 30 is arranged on the front side of the first rolling brush 20, and the first scraping strip 30 contacts the surface to be cleaned 200 in a natural state; a position adjusting mechanism 50, which is used to adjust the displacement of the first scraping strip 30 in the vertical direction.

[0081] In one embodiment, as shown in 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.

[0082] 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.

[0083] 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.

[0084] 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.

[0085] like Figure 1 andFigure 2 As shown, the first scraping strip 30 is provided with a wind passing part 40 for facilitating the airflow to pass through and enter the first rolling brush 20. The current cleaning device has a drying function. When the air outlet of the drying airflow is arranged in front of the rolling brush, the wind passing part 40 is arranged on the first scraping strip 30 arranged in front, so that the drying airflow can be transmitted to the position of the first rolling brush 20, and the drying of the first rolling brush 20 is not affected.

[0086] As shown in Figure 7 and Figure 8 In one embodiment, the shell 10 includes a first shielding part 11 arranged in front of the first rolling brush 20, the first scraping strip 30 extends beyond the first shielding part 11, and the first scraping strip 30 or the first shielding part 11 is provided with a wind passing part 40 for facilitating the airflow to pass through and enter the first rolling brush. This design can also deliver the hot air flow of the drying to the first rolling brush 20 to dry the first rolling brush 20.

[0087] In one embodiment, no matter where the wind passing part 40 is arranged, the wind passing part 40 can be a plurality of spaced-apart through holes or long and narrow extension grooves. The drying airflow is not a high-speed airflow. While solving the problem of too much water stain, based on the position of the first scraping strip 30, the arrangement of the plurality of through holes or long and narrow extension grooves can realize the drying of the first rolling brush 20 while ensuring the negative pressure of the whole cleaning device.

[0088] As shown in Figure 16 The difference between the floor brush assembly according to the fifth aspect of the present application and the floor brush assemblies according to the first to fourth aspects of the present application is that the floor brush assembly according to the fifth aspect of the present application further includes a second scraping strip 70 on the basis of the floor brush assemblies according to the first to fourth aspects of the present application.
