[0161] The embodiments of the present application will be described in detail below with reference to the accompanying drawings. The embodiments described with reference to the accompanying drawings are exemplary. In the following embodiment description, "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 brush shaft extends.

[0162] The present application provides a cleaning system, which comprises a cleaning device and a base station for charging the cleaning device. The cleaning device is provided with a brush assembly. According to the brush assembly 100 of the embodiment of the present application, the problem of excessive water stains after wet treatment can be solved, and the user experience is improved. Different embodiments of the brush assembly will be described below with reference to the accompanying drawings.

[0163] According to the brush assembly of the first aspect of the present application, the scheme mainly protects the brush assembly with a brush and a scraping strip in front of the brush for contacting the surface to be cleaned. The brush assembly of the first aspect of the present application will be described below with reference to the accompanying drawings.

[0164] As Figures 1 to 3As shown, the first aspect embodiment of the floor brush assembly 100 is used in contact with the surface to be cleaned 200. The floor brush assembly 100 comprises a housing 10, a first roller brush 20 and a wiper strip assembly. The first roller brush 20 is rotatably arranged on the housing 10. The wiper strip assembly comprises a first wiper strip 30, the first wiper strip 30 comprises 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 is in contact with the surface to be cleaned 200 in a natural state. The first wiper strip 30 is made of soft material, and when the cleaning equipment moves forward, the first wiper strip 30 deforms backward, and dust can enter the interior of the floor brush assembly 100 through the gap between the first wiper strip 30 and the surface to be cleaned 200 under the action of negative pressure. When the cleaning equipment moves backward, the first wiper strip 30 deforms forward, and at this time, the first wiper strip 30 in contact with the surface to be cleaned 200 can assist in scraping the water stains on the floor, thereby reducing the residual water stains.

[0165] In order to further improve the cleaning effect, especially the cleaning effect of large garbage, a plurality of first protrusions 33 facing the forward direction are arranged on the cantilever end 32 near the surface to be cleaned 200, and the plurality of first protrusions 33 are arranged on one side of the first wiper strip 30 facing the front. The floor brush assembly 100 has a first state of moving forward and a second state of moving backward, 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 wiper 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 is formed when the floor brush assembly 100 moves forward, thereby improving the pickup effect of large garbage and improving the cleaning efficiency of the cleaning equipment.

[0166] As shown in Figure 1 and Figure 2 The first wiper strip 30 is provided with an air passing portion 40 for facilitating the airflow to pass through and enter the first roller brush 20. The current cleaning equipment all has a drying function, and when the air outlet of the drying airflow is arranged in front of the roller brush, the air passing portion 40 is arranged on the first wiper strip 30 arranged in front, so that the drying airflow can be transmitted to the position of the first roller brush 20, and the drying of the first roller brush 20 is not affected.

[0167] Of course, in other embodiments, as shown in Figure 7 and Figure 8 The housing 10 comprises a first shielding portion 11 surrounding at least part of the first roller brush 20 in front, the first wiper strip 30 extends beyond the first shielding portion 11, and the first shielding portion 11 is provided with an air passing portion 40 for facilitating the airflow to pass through and enter the first roller brush 20. This design can also transmit the hot air flow of the drying to the first roller brush 20 to dry the first roller brush 20.

[0168] 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.

[0169] 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.

[0170] 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.

[0171] 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.

[0172] 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 be provided on the shell for the user to step on the foot pedal, 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. a 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-mentioned 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-operated operating assembly 60 is generally set more rearward, it is necessary to set 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.

[0173] According to the floor brush assembly of the second aspect embodiment of the utility model, the floor brush assembly mainly protects the scheme that the rolling brush has a first protruding part, the rolling brush has a scraping strip in contact with the surface to be cleaned in the front, and the scraping strip has a first protruding part. 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.

[0174] The floor brush assembly structure of the second 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.

[0175] As shown in the drawings, Figure 1 The floor brush assembly 100 of the second aspect embodiment is used to contact the surface to be cleaned, and the floor brush assembly 100 comprises a shell 10, a first rolling brush 20 rotatably arranged on the shell 10, a scraping strip assembly comprising a first scraping strip 30 arranged on the front side of the first rolling brush 20, the first scraping strip 30 contacting the surface to be cleaned 200 in a natural state, a plurality of first protruding parts 33 arranged at intervals being arranged at the position of the first scraping strip 30 close to the surface to be cleaned 200, and the plurality of first protruding parts 33 being arranged on the side of the first scraping strip 30 facing the front. The floor brush assembly 100 has a first state of advancing and a second state of retreating, as shown in the drawings, Figure 4 and Figure 5 In the first state, at least part of the first protruding parts 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 protruding parts 33. As shown in the drawings, Figure 6As shown in the second state, the first scraping strip 30 is in contact with the surface 200 to be cleaned. By arranging the first protrusions 33, a channel for large garbage to pass through can be formed when the brush assembly 100 advances, thereby improving the pickup effect of the large garbage and improving the cleaning efficiency of the cleaning device.

[0176] In one embodiment, the first scraping strip 30 comprises a cantilever end which is in contact with the surface to be cleaned in a natural state, and the first protrusions 33 are not in contact with the surface to be cleaned in the natural state.

[0177] As shown in the second state, the first scraping strip 30 is in contact with the surface 200 to be cleaned. By arranging the first protrusions 33, a channel for large garbage to pass through can be formed when the brush assembly 100 advances, thereby improving the pickup effect of the large garbage and improving the cleaning efficiency of the cleaning device. Figure 2 、 Figure 7 and Figure 8 In one embodiment, the housing 10 comprises a first shielding portion 11 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, which is used to facilitate the airflow to pass through and enter the first roller brush. The current cleaning device has a drying function. When the air outlet of the drying airflow is arranged in front of the roller brush, the wind passing portion 40 can be arranged on the first scraping strip 30 arranged in front, so that the drying airflow can be transmitted to the position of the first roller brush 20, without affecting the drying of the first roller brush 20.

[0178] In one embodiment, the wind passing portion 40 can be a plurality of spaced-apart through holes or long and narrow extension grooves, regardless of the arrangement position of the wind passing portion 40. The drying airflow is not a high-speed airflow. When the problem of excessive water stains is solved, 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 while ensuring the negative pressure of the entire dust collection device.

[0179] In one embodiment, the first scraping strip 30 can also be displaced in the vertical direction. As shown in the second state, Figures 9 to 12 The brush assembly 100 comprises a position adjusting mechanism 50 for adjusting the displacement of the first scraping strip 30 in the vertical direction. The position adjusting mechanism 50 comprises a slot portion 51 and a sliding portion (not shown) which can move in the slot portion 51. The relative movement of the sliding portion and the slot portion 51 drives the first scraping strip 30 to move and displace in the vertical direction.

[0180] In one embodiment, as shown in the second state, 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.

[0181] 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 first scraping strip 30 is passively moved in the up-down direction because the sliding portion only has displacement in the left-right direction and has no displacement 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 to be cleaned 200, so that the large garbage passes more smoothly.

[0182] As shown in the drawings, 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-mentioned 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.

[0183] According to the floor brush assembly of the third aspect of the present application, the floor brush assembly mainly protects 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 an air passage for drying the hot air drying airflow. This embodiment is the same as the floor brush assembly of the second aspect of the present application, 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 floor brush assembly of the second aspect of the present application will be described below with reference to the drawings.

[0184] The floor brush assembly structure of the third aspect of the present application can be the same as that of the first aspect of the present application, so the drawings adopt the drawings of the floor brush assembly of the first aspect of the present application, 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 of the present application. In this embodiment, the effects of each technical solution will not be repeated.

[0185] As Figure 1 , Figure 2 , Figure 7 illustrated, the third aspect embodiment of the brush assembly 100 is used to contact the surface to be cleaned, the brush assembly comprises: a housing 10; a first roller brush 20 rotatably arranged in the housing 10; a scraper strip assembly, the scraper strip assembly comprises a first scraper strip 30, the first scraper strip 30 is arranged on the front side of the first roller brush 20, the first scraper strip 30 contacts the surface to be cleaned 200 in a natural state, and a wind passing portion 40 is arranged on the first scraper strip 30 or the housing 10, the wind passing portion 40 is used to facilitate the airflow to pass through and enter the first roller brush. The wind passing portion 40 is used to facilitate the airflow to pass through and enter the first roller brush 20. This design can also deliver the hot air flow for drying to the first roller brush 20 to dry the first roller brush 20.

[0186] The housing 10 comprises a first shielding portion 11 located in front of the first roller brush 20, the first scraper strip 30 extends beyond the first shielding portion 11, and the wind passing portion 40 is arranged on the first shielding portion 11.

[0187] In an 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 drying airflow is not a high-speed airflow, and while solving the problem of excessive water stains, based on the position of the first scraper 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 while ensuring the negative pressure of the entire suction cleaning device.

[0188] In an embodiment, the first scraper strip 30 is provided with a plurality of first convex portions 33 facing the forward direction at a position close to the surface to be cleaned 200, and the plurality of first convex portions 33 are arranged on the side of the first scraper strip 30 facing the front. The brush assembly 100 has a first advancing state and a second retreating state, as shown in Figure 4 and Figure 5 , in the first state, at least part of the first convex portions 33 contact the surface to be cleaned 200, and a channel is formed between adjacent two first convex portions 33 for the garbage to pass through. As shown in Figure 6 , in the second state, the first scraper strip 30 contacts the surface to be cleaned 200. By arranging the first convex portions 33, a channel for large garbage to pass through can be formed when the brush assembly 100 advances, which improves the pickup effect of large garbage and improves the cleaning efficiency of the cleaning device.

[0189] In an embodiment, the first scraper strip 30 can also displace in the vertical direction. As shown in Figures 9 to 12As shown, the floor brush assembly 100 comprises a position adjusting mechanism 50 for adjusting the displacement of the first scraping strip 30 in the vertical direction. The position adjusting mechanism 50 comprises a slot portion 51 and a sliding portion (not shown) which is movable in the slot portion 51, and the relative movement between the slot portion 51 and the sliding portion causes the first scraping strip 30 to move in the vertical direction.

[0190] In one embodiment, as shown in the drawings, Figure 11 The position adjusting mechanism 50 comprises an operating assembly 52, and the first scraping strip 30 is provided with the slot portion 51, and the operating assembly 52 is provided with the sliding portion. Of course, the reverse arrangement is also possible, that is, the first scraping strip 30 is provided with the sliding portion, and the operating assembly 52 is provided with the slot 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 causes the first scraping strip 30 to move up and down. In this embodiment, the user can manually dial the operating assembly 52 to operate the first scraping strip 30 to lift.

[0191] In order to facilitate the left-right movement of the operating assembly 52 to cause the first scraping strip 30 to move up and down, the slot portion 51 extends upwardly in the vertical direction. In this way, when the sliding portion moves in the slot portion 51, the sliding portion only has displacement in the left-right direction without displacement in the up-down direction, so that the first scraping strip 30 is passively moved in the up-down direction, thereby achieving the effect of lifting the first scraping strip 30, and providing more space between the first scraping strip 30 and the surface to be cleaned 200, so that the large garbage passes more smoothly.

[0192] As shown in the drawings, Figures 13 to 15 In another embodiment, the user can also not need to manually dial, but can use the foot pedal method. A foot pedal is arranged on the housing for the user to step on, and the up-down movement of the foot pedal causes the first scraping strip 30 to move up and down. 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 slot portion 51 of the above-mentioned 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 slot portion. Since the foot pedal type 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 achieve the lifting of the first scraping strip 30.

[0193] According to the fourth aspect of the present application, the floor brush assembly mainly protects a rolling brush, the rolling brush has a scraping strip in contact with the surface to be cleaned in the front, and has an adjusting mechanism for causing the scraping strip to displace in the vertical direction. Compared with the first aspect, 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 will be described below with reference to the drawings.

[0194] The brush assembly structure of the fourth 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 are not repeated.

[0195] As shown in Figure 1 , Figure 2 and Figure 5 , the brush assembly 100 of the fourth aspect embodiment is used in contact with the surface to be cleaned 200, and the brush assembly 100 comprises: a housing 10; a first roller brush 20 rotatably arranged in the housing 10; a scraper assembly comprising a first scraper 30 arranged on the front side of the first roller brush 20, the first scraper 30 being in contact with the surface to be cleaned 200 in a natural state; and a position adjusting mechanism 50 for adjusting the displacement of the first scraper 30 in the vertical direction.

In this embodiment, the user can manually operate the operating assembly 52 to lift the first scraper 30.

[0197] In order to facilitate the left-right movement of the operating assembly 52 to drive the up-down movement of the first scraper 30, 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 displacement in the left-right direction without displacement in the up-down direction, so the first scraper 30 is passively moved in the up-down direction, thereby achieving the effect of lifting the first scraper 30, and providing more space between the first scraper 30 and the surface to be cleaned 200, so that large garbage can pass more smoothly.

Since the foot-operated operating assembly 60 is generally set more rearward, it is necessary to set the transmission assembly to transmit the force from the side of the floor brush assembly to the first scraping strip 30 to realize the lifting of the first scraping strip 30.

[0199] In one embodiment, a plurality of protrusions 33 facing the advancing direction are arranged at positions of the first scraping strip 30 close to the surface to be cleaned 200, and the plurality of protrusions 33 are arranged on the side of the first scraping strip 30 facing the front.

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 floor brush assembly 100 advances, thereby improving the pickup effect of large garbage and improving the cleaning efficiency of the cleaning device.

[0200] As shown in Figure 1 and Figure 2 In one embodiment, the first scraping strip 30 is provided with an air passing part 40 for facilitating the airflow to pass through and enter the first roller brush 20.
