[0071] like Figure 1-Figure 10 As shown, a floor brush 100 of a cleaning device 200 according to an embodiment of the present invention comprises: a mounting seat 30, the mounting seat 30 defines a suction channel 31; a cleaning member 20, the cleaning member 20 is rotatably mounted on the mounting seat 30. A liquid spraying mechanism 10, the liquid spraying mechanism 10 is mounted on the mounting seat 30 and is used to spray liquid to the cleaning member 20, the surface of the liquid spraying mechanism 10 opposite to the cleaning member 20 is configured as an arc surface, the cleaning member 20 is suitable for rotating toward a first direction and a second direction, the first direction and the second direction are opposite, the cleaning member 20 is suitable for cleaning the surface to be cleaned when rotating toward the first direction, and is suitable for cleaning the liquid spraying mechanism 10 when rotating toward the second direction, specifically, the cleaning member 20 is suitable for cleaning the arc surface of the liquid spraying mechanism 10 when rotating toward the second direction.

[0072] Please continue to see Figure 3 As shown, the cleaning member 20 is suitable for rotating in a first direction and a second direction, the first direction and the second direction are opposite, and the cleaning member 20 is suitable for cleaning the liquid spraying mechanism 10 when rotating in the first direction or the second direction. Figure 3 The direction indicated by the dashed arrow is the rotation direction of the cleaning member 20. The first direction and the second direction can be the rotation directions of the cleaning member 20, respectively, and the first direction and the second direction can be opposite. Figure 3 The dotted arrow in the middle indicates the counterclockwise direction, and the second direction can be Figure 3 The first direction may be the clockwise direction indicated by the dashed arrow; or Figure 3 The dotted arrow in the middle indicates the clockwise direction, and the second direction can be Figure 3The dotted arrow in the figure indicates the counterclockwise direction. The embodiments of the present invention do not specifically limit this. The rotation direction of the cleaning member 20 when cleaning the floor can be one of the first direction and the second direction, and the rotation direction of the cleaning member 20 when cleaning the spray mechanism 10 can be the other of the first direction and the second direction. It should be noted that the rotation direction of the cleaning member 20 when cleaning the floor is opposite to the rotation direction of the cleaning member 20 when cleaning the spray mechanism 10. For example, the cleaning member 20 can rotate in the first direction when cleaning the floor, and the cleaning member 20 needs to rotate in the second direction when cleaning the spray mechanism 10, and vice versa. The following embodiments are explained by taking the example that the first direction can be counterclockwise and the second direction can be clockwise. Figure 1 and Figure 3 As shown in FIG. 1 , when the cleaning member 20 rotates toward the first direction, dirt, dust, hair, sewage, and other garbage attached to the ground can be adsorbed on the outer surface of the cleaning member 20, and as the cleaning member 20 rotates, the garbage can be transported to the suction channel 31, and finally collected to the suction channel 31. Figure 2 The garbage is stored in the recycling box 201 of the cleaning device 200 so that the user can clean it regularly. When the cleaning member 20 rotates in the second direction, the cleaning member 20 can drive the liquid to flush the liquid spraying mechanism 10, so that the garbage adsorbed and accumulated on the liquid spraying mechanism 10 can flow with the liquid to the suction channel 31 inside the mounting seat 30, thereby achieving the purpose of automatic cleaning of the liquid spraying mechanism 10 by the cleaning member 20, and effectively solving the problem of poor liquid flow caused by the liquid spraying mechanism 10 being blocked by garbage. At the same time, it can also effectively prevent the garbage from accumulating on the surface of the liquid spraying mechanism 10 to produce odor, thereby improving the user experience.

[0073] In some embodiments of the present invention, when the cleaning member 20 rotates toward the second direction, the liquid spraying mechanism 10 can deliver liquid to the surface of the cleaning member 20, so that the cleaning member 20 can drive the liquid to clean and flush the liquid spraying mechanism 10, so as to ensure that the liquid spraying mechanism 10 can be kept clean and tidy. At the same time, controlling the cleaning member 20 to rotate toward the first direction and the second direction can effectively prevent the surface of the cleaning member 20 from being deformed, so that the surface of the cleaning member 20 can be quickly dried, thereby reducing the number of user maintenance and effectively improving the user experience.

[0074] Thus, by cleaning the liquid spraying mechanism 10 when the cleaning member 20 rotates toward the second direction, the floor brush 100 has an automatic cleaning function, which can effectively prevent garbage from gathering on the surface of the liquid spraying mechanism 10, thereby improving the user experience.

[0075] In some embodiments of the present invention, the liquid spraying mechanism 10 and the suction channel 31 are both located on the inner side of the cleaning member 20, the liquid spraying mechanism 10 is located above the suction channel 31, the liquid spraying mechanism 10 includes a main body 118 and a spraying portion 119, the spraying portion 119 is installed on the main body 118, the spraying portion 119 is provided with a liquid outlet 111, the main body 118 is provided with a liquid inlet 113 and a liquid flow channel 114, the liquid flow channel 114 connects the liquid inlet 113 and the liquid outlet 111, and in the height direction of the floor brush 300, the liquid outlet 111 is located between the central axis of the cleaning member 20 and the top of the cleaning member 20.

[0076] Specifically, the mounting seat 30 may be a cylindrical structure, a rectangular parallelepiped structure, or a cubic structure, which is not specifically limited in the embodiments of the present invention. The following embodiments are explained by taking the mounting seat 30 with a rectangular parallelepiped structure as an example. Figure 1 and Figure 3 As shown, mounting grooves 34 can be respectively provided on opposite sides of the mounting seat 30 in the width direction. Figure 1 In the direction indicated by Y in the figure, the cross-sectional shape of the mounting groove 34 can be an arc shape, and the mounting groove 34 can extend along the length direction of the mounting seat 30. The length direction of the mounting seat 30 can be Figure 1 The lower end of the mounting groove 34 can be opened, the number of the mounting grooves 34 can match the cleaning member 20, the cleaning member 20 can be detachably mounted in the mounting groove 34, and the axial direction of the cleaning member 20 can be parallel to the length direction of the mounting seat 30. The suction channel 31 can be arranged corresponding to the cleaning member 20, and the suction channel 31 can be connected to the cleaning member 20 through a recovery pipeline (not shown in the figure). Figure 2 The cleaning device 200 is connected to the recycling box 201. A motor (not shown in the figure) can be arranged in the mounting seat 30, and the motor can be used to suck air into the suction channel 31. In this way, under the action of negative air pressure, the dirt, hair, sewage and other garbage cleaned and collected by the cleaning member 20 can be sucked into the suction channel 31, and then can be collected by the recycling box 201 through the suction channel 31, so that the floor brush 100 can remove the dirt, hair and sewage attached to the ground, thereby achieving the technical effect of the floor brush 100 cleaning the ground.

[0077] Furthermore, the extension direction of the liquid spraying mechanism 10 may be parallel to the axial direction of the cleaning member 20, the liquid spraying mechanism 10 may be arranged opposite to the cleaning member 20, and the liquid spraying mechanism 10 may be connected to the cleaning member 20 through a liquid pipeline (not shown in the figure). Figure 2The liquid storage tank 202 of the cleaning device 200 is connected, and the spray mechanism 10 can spray liquid toward the surface of the cleaning member 20. In this way, the liquid spray mechanism 10 can spray liquid toward the surface of the cleaning member 20 to keep the surface of the cleaning member 20 moist, so that the cleaning member 20 can remove fine granular garbage such as dust attached to the ground, thereby effectively improving the cleaning degree of the cleaning member 20.

[0078] The cleaning member 20 is parallel to the liquid spraying mechanism 10, which can make the wetting effect of the cleaning member 20 more uniform. Since the cleaning member 20 is parallel to the liquid spraying mechanism 10, that is, the outer surface of the liquid spraying mechanism 10 is at the same distance from the outer peripheral surface of the cleaning member 20, and the liquid outlet 111 is arranged on the main body 118, and the liquid outlet 111 is at the same distance from the outer peripheral surface of the cleaning member 20, it is conducive to the liquid in the liquid outlet 111 flowing the same distance to spray to the cleaning member 20, which can make the wetting effect more uniform. In addition, the parallel arrangement of the cleaning member 20 and the liquid spraying mechanism 10 can effectively reduce the volume of the floor brush 100, avoid position interference with other structures in the floor brush 100, and make the structural design of the floor brush 100 more reasonable.

[0079] The embodiment of the present invention does not impose any special restrictions on the number of cleaning members 20. Two cleaning members 20 can be installed on the mounting seat 30, and the two cleaning members 20 are arranged opposite to each other in the width direction of the mounting seat 30 to improve the cleaning effect and the cleaning efficiency of the floor brush 100. In addition, two liquid spraying mechanisms 10 can be correspondingly arranged on the mounting seat 30 to wet the two cleaning members 20 respectively.

[0080] Please continue to see Figure 6-Figure 10 As shown, the liquid inlet 113 is provided on the body 118, the liquid outlet 111 is provided on the spraying portion 119, and a liquid flow channel 114 is constructed on the body 118 to connect the liquid inlet 113 and the liquid outlet 111, or the body 118 and the spraying portion 119 jointly define the liquid flow channel 114. A plurality of liquid outlets 111 may be provided on the spraying portion 119, and the plurality of liquid outlets 111 are all provided at the top of the spraying portion 119 and are spaced apart along the extension direction of the spraying portion 119 to increase the water output.

[0081] In the height direction of the floor brush 100, the liquid outlet 111 is located between the central axis of the cleaning member 20 and the top of the cleaning member 20. This arrangement can reasonably set the height of the liquid outlet 111 from the central axis of the cleaning member 20 in the height direction of the floor brush 100, which can increase the range of the liquid sprayed from the liquid outlet 111 and reduce the volume of the floor brush 100. On the other hand, it can prevent the liquid outlet 111 from facing the cleaning member 20, thereby preventing the dirt thrown out by the cleaning member 20 during the cleaning process from clogging the liquid outlet 111 and preventing the dirt from gathering at the liquid outlet 111, which is conducive to improving the cleaning efficiency of the floor brush 100.

[0082] According to the floor brush 100 provided by the embodiment of the present invention, by arranging the liquid spraying mechanism 10 on the mounting seat 30, and the liquid spraying mechanism 10 is arranged opposite to the cleaning member 20, so that the liquid spraying mechanism 10 can spray liquid toward the surface of the cleaning member 20 in real time, so that the outer surface of the cleaning member 20 can be kept wet, so that the cleaning member 20 can remove stains, dust, hair or sewage and other garbage attached to the ground, thereby effectively improving the cleaning degree of the cleaning member 20. By using the liquid spraying member 70 to spray liquid toward the inner wall 32 of the suction channel 31, the liquid sprayed by the liquid spraying member 70 can wash away the dust and other debris attached to the inner wall 32 of the suction channel 31, so as to prevent the dust and other debris from clogging the suction channel 31, and also avoid the occurrence of odor and other problems in the suction channel 31. By setting the liquid outlet 111, and in the height direction of the floor brush 100, the liquid outlet 111 can be located between the central axis of the cleaning member 20 and the top of the cleaning member 20, and the liquid (such as water flow) in the liquid spray mechanism 10 flows through the liquid outlet 111 to form a waterfall-like water spray flow to wet the cleaning member 20. On the one hand, the contact area between the liquid and the cleaning member 20 can be increased, and the liquid and the cleaning member 20 are in full contact to achieve more uniform wetting of the cleaning member and improve the cleaning effect. On the other hand, the liquid outlet 111 is avoided from facing the cleaning member, and the liquid outlet 111 is avoided from being blocked after long-term use, thereby avoiding affecting the cleaning efficiency and greatly improving the user experience.

[0083] It should be noted that the liquid output by the liquid spraying mechanism 10 may be a detergent or water, or the cleaning device 200 may add detergent into the liquid storage tank 202 of the cleaning device 200 according to actual usage, or detergent may be arranged in the liquid flow channel 114 of the liquid spraying mechanism 10, and the water becomes washing water with a certain cleaning ability when flowing through the liquid flow channel 114, etc. This embodiment of the present invention does not make any specific limitation on this.

[0084] In some embodiments of the present invention, the cleaning member 20 and the liquid spraying mechanism 10 can be arranged adjacent to each other, and the cleaning member 20 and the liquid spraying mechanism 10 are arranged to be spaced apart, so that on the one hand, the liquid sprayed from the liquid outlet 111 can wet the cleaning member 20 more quickly, and at the same time, it is conducive to realizing the compactness of the overall structure of the floor brush 100. On the other hand, the cleaning member 20 is spaced a certain distance from the liquid spraying mechanism 10, and then the liquid outlet 111 can have a reasonable height relative to the outer peripheral surface of the cleaning member 20, which is more conducive to the liquid outlet 111 to realize waterfall-like water spraying, and the wetting effect of the cleaning member 20 is more uniform. At the same time, during the rotation process of the cleaning member 20, the cleaning member 20 can throw out liquid to realize the self-cleaning function of the liquid spraying mechanism 10 through the distance between the cleaning member 20 and the liquid spraying mechanism 10, which is conducive to avoiding the blockage of the liquid outlet 111 and improving the cleaning efficiency of the floor brush 100.

[0085] In some embodiments of the present invention, at least one liquid outlet 111 can be arranged near the top of the liquid spraying mechanism 10, so that the liquid flowing into the liquid spraying mechanism 10 can obtain a certain potential energy by utilizing the height of the liquid spraying mechanism 10 itself, which is more conducive to forming a waterfall-like water spray when the liquid flows out of the liquid outlet 111, achieving a good wetting effect, and thus the cleaning effect of the floor brush 100 is good. Moreover, when the liquid spraying mechanism 10 is in a certain position relative to the cleaning member 20, the thickness of the floor brush 100 can be effectively reduced, the space occupied by the place can be reduced, and the applicability flexibility of the floor brush 100 can be improved. That is to say, in the up-down direction, the liquid outlet 111 can be close to the top or upper end of the liquid spraying mechanism 10, and the liquid can flow from top to bottom; in the front-back direction, the liquid outlet 111 extends toward the liquid spraying mechanism 10, and the liquid can be collected when the liquid is discharged, forming a waterfall-like water spray, thereby improving the cleaning effect.

[0086] Furthermore, the plurality of liquid outlets 111 can effectively increase the flow rate of liquid sprayed by the liquid spraying mechanism 10. Moreover, the plurality of liquid outlets 111 are all configured as strip-shaped outlets, and the plurality of liquid outlets 111 can be spaced apart along the axial direction of the cleaning member 20. Furthermore, the plurality of liquid outlets 111 are sequentially spaced apart along the axial direction of the cleaning member 20, and while a waterfall-like water spray can be formed, the range of the liquid sprayed from the liquid outlet 111 can be effectively increased, so that the liquid spraying mechanism 10 can wet the cleaning member 20 more quickly, and the effect of wetting the cleaning member 20 is more uniform, and a better cleaning effect can be achieved.

[0087] A cylindrical opening (not shown in the figure) may be provided between at least two of the plurality of liquid outlets 111, and the cylindrical opening is also used to spray liquid onto the cleaning member 20. Thus, a waterfall-like water spray can be formed at the liquid outlet 111 to achieve a uniform effect of wetting the cleaning member 20, and the cylindrical liquid outlet 111 can effectively save water, avoiding the user from frequently replenishing liquid during use, and avoiding affecting the user's use experience.

[0088] It should be noted that the number of cylindrical openings between at least two liquid outlets 111 can be flexibly set according to actual conditions, and one or more cylindrical openings can be set. For example, in some embodiments, the floor brush 100 needs to clean an area with less dirt, and multiple cylindrical openings can be set, which can save water while achieving a cleaning effect and avoid users from frequently replenishing liquid. In other embodiments, the floor brush 100 needs to clean an area with more dirt, and one cylindrical opening can be set. Flexible setting of the cylindrical openings can meet different cleaning needs.

[0089] In some embodiments of the present invention, the liquid outlet 111 can be provided in multiple numbers, and the multiple liquid outlets 111 are provided at the same height, so as to avoid the uneven wetting effect of the cleaning member 20 caused by the inconsistent heights of the liquid outlets 111. Specifically, since the multiple liquid outlets 111 are provided at the same height, it is conducive to the liquid sprayed from the multiple liquid outlets 111 to wet the cleaning member 20 along the axial direction of the cleaning member 20, so that the wetting effect that can be achieved is more uniform. For example, in some embodiments, the multiple liquid outlets 111 are all long strips, each of which can achieve waterfall-style water spraying, and the long strips are provided at the same height, so that in the axial direction of the cleaning member 20, the wetting effect of the cleaning member 20 is more uniform, and the wetting effect that can be achieved is better.

[0090] To achieve better wetting effect, in some embodiments of the present invention, Figure 7 As shown, the liquid outlet 111 of the liquid spraying mechanism 10 is provided as one, and the liquid outlet 111 is a strip-shaped outlet, and the liquid outlet 111 extends along the axial direction of the cleaning member 20, so that when multiple liquid outlets 111 are provided, it can be avoided that there is a gap between the multiple liquid outlets 111 so that the outer peripheral surface of a part of the cleaning member 20 cannot face the liquid outlet 111. For example, the liquid outlet 111 can extend from one end of the liquid spraying mechanism 10 to the other end, thereby, in the axial direction of the cleaning member 20, each part of the cleaning member 20 can be wetted by the liquid sprayed by the liquid spraying mechanism 10, and the entire cleaning member 20 can be wetted without leaving a dead angle by rotating the cleaning member 20, and while increasing the flow rate of the liquid sprayed by the liquid outlet 111, the liquid sprayed by the liquid outlet 111 can fully contact with the cleaning member 20, and the wetting effect achieved is more uniform.

[0091] Please continue to see Figure 8 As shown, in some embodiments of the present invention, the main body 118 is formed with a mounting groove 1191, the mounting groove 1191 is open toward the end of the cleaning member 20, and the spraying portion 119 is arranged in the mounting groove 1191. Specifically, the extension direction of the mounting groove 1191 can be parallel to the extension direction of the main body 118, the mounting groove 1191 can be recessed in a direction away from the spraying portion 119, and the opening direction of the mounting groove 1191 can be opposite to the spraying portion 119. Further, an assembly part (not shown in the figure) can be arranged at an end of the spraying portion 119 opposite to the main body 118, and the assembly part can be arranged opposite to the mounting groove 1191. Such an arrangement can be connected by the assembly part and the mounting groove 1191, so that the spraying portion 119 is installed on the main body 118, thereby improving the stability of the spraying portion 119 and the main body 118 after connection.

[0092] Please continue to see Figure 8As shown, in some embodiments of the present invention, the end surface of the main body 118 close to the cleaning member 20 is configured as a first curved surface 1192, and the end surface of the spraying portion 119 close to the cleaning member 20 is configured as a second curved surface 1193. The first curved surface 1192 and the second curved surface 1193 are coplanar to form the curved surface in the above embodiment. Specifically, the first curved surface 1192 and the second curved surface 1193 can together constitute the curved surface 112, and the curved surface 112 can improve the structural strength of the liquid spraying mechanism 10, and the curved surface 112 is not easy to retain dirt. The curved surface 112 is suitable for being arranged corresponding to the cleaning member 20, such as adjacent or opposite arrangement. In this way, when the liquid rotates with the cleaning member 20, it is affected by the centrifugal force, and the liquid can flush the curved surface 112, and the curved surface 112 has no cleaning dead corners, and it is not easy to leave sewage and dirt, which is conducive to improving the cleaning effect. That is to say, when the floor brush 100 is in use, the curved surface 112 of the liquid spraying mechanism 10 can prevent dirt from being easily retained on the liquid spraying mechanism 10, and during the cleaning process, the cleaning member 20 can both clean the floor and perform self-cleaning on the liquid spraying mechanism 10, thereby improving the cleaning effect of the floor brush 100.

[0093] In some embodiments of the present invention, the angle between the tangent line at the lower end of the arc surface 112 and the horizontal plane is β, which satisfies the relationship: 0°<β≤90°. In other words, the angle between the tangent line at the lower end of the arc surface 112 and the horizontal plane is an acute angle or a right angle, so that when the water at the lower end of the arc surface 112 flows out, the pressure and gravity are in the same direction, which is convenient for rapid drainage, and can improve the drainage effect of the lower end of the liquid spraying mechanism 10, avoid sewage staying at the lower end of the arc surface 112, prevent garbage and other objects from remaining on the arc surface 112, and facilitate the surface cleaning of the arc surface 112.

[0094] In some embodiments of the present invention, the arcuate surface 112 is arranged corresponding to the cleaning member 20, and the arcuate surface 112 is recessed toward the inside of the liquid spray body 11, so that the arcuate surface 112 can surround the outer peripheral surface of the cleaning member 20, which is conducive to the adaptation of the arcuate surface 112 to the cleaning member 20, so that the cleaning member 20 can clean the arcuate surface 112 during operation or rotation, and can also improve the spatial layout effect.

[0095] Furthermore, the first curved surface 1192 and the second curved surface 1193 may be located on the same spherical surface to jointly form the curved surface 112. The curved surface 112 may be an arc, and such a configuration may improve the matching degree between the liquid spraying mechanism 10 and the cleaning member 20. When the cleaning member 20 is running or rotating, the outer surface of the cleaning member 20 may maintain a consistent spacing distance with the curved surface 112, thereby improving the cleaning effect and avoiding interference between the cleaning member 20 and the curved surface 112 during the rotation process, thereby ensuring smooth rotation of the cleaning member 20.

[0096] Please continue to see Figure 8As shown, in some embodiments of the present invention, the first curved surface 1192 and the second curved surface 1193 are both adapted to the shape of the cleaning member 20. That is, the curvature of the first curved surface 1192 and the second curved surface 1193 can be set according to the shape of the cleaning member 20, so that the curvature of the first curved surface 1192 and the second curved surface 1193 matches the curvature of the outer surface of the cleaning member 20, which can further improve the cleaning effect of the cleaning member 20 and improve the self-cleaning function of the floor brush 100.

[0097] Please continue to see Figure 6 and Figure 8 As shown, in some embodiments of the present invention, the liquid outlet 111 is arranged near the upper end of the spraying portion 119. Specifically, the liquid outlet 111 can be located near the upper part of the liquid spraying mechanism 10, and the arrangement height of the liquid outlet 111 is higher than the central axis of the cleaning member 20, but the arrangement height of the liquid outlet 111 does not exceed the top of the cleaning member 20. The liquid outlet 111 can spray water upward, not directly facing the cleaning member 20, forming a waterfall-like water spray, and the water is sprayed onto the cleaning member 20 without blocking the liquid outlet 111. At the same time, the sprayed water can fully contact the cleaning member 20 during the downward flow, so that the cleaning member 20 is more evenly wetted. It should be noted that the embodiment of the present invention does not impose any special restrictions on the shape of the liquid outlet 111. For example, the liquid outlet 111 can be a strip-shaped outlet, a column-shaped outlet, etc.

[0098] During operation, since at least one liquid outlet 111 is arranged close to the top of the liquid spraying mechanism 10, the distance between the liquid outlet 111 and the central axis of the cleaning member 20 in the height direction of the floor brush 100 is relatively large. By reasonably setting the number of liquid outlets 111, for example, multiple liquid outlets 111 are densely distributed, the liquid sprayed from the multiple liquid outlets 111 can be gathered into a waterfall-like water flow, thereby more evenly wetting the cleaning member 20 and improving the cleaning effect of the cleaning device 200.

[0099] Optionally, the liquid outlet 111 may also be disposed at a position close to the bottom or lower end of the arc-shaped surface 112 , and in this case, the liquid flows out of the liquid outlet 111 and is directly sprayed onto the cleaning member 20 .

[0100] Please continue to see Figure 6-Figure 10 As shown, in some embodiments of the present invention, there is at least one liquid outlet 111, and at least one liquid outlet 111 is a strip-shaped outlet. Specifically, there can be multiple liquid outlets 111, which can effectively increase the flow rate of the sprayed liquid. The liquid outlet 111 can be used to spray liquid onto the cleaning member 20 to wet the cleaning member 20 and improve the cleaning effect of the floor brush 100. In addition, in the height direction of the floor brush 100 (such as Figure 1In the embodiment of the present invention, the liquid spray mechanism 10 is provided with a plurality of liquid outlets 111, some of which are directly opposite to the cleaning member 20, and the remaining liquid outlets 111 can be located between the central axis of the cleaning member 20 and the top of the cleaning member 20. Furthermore, the setting height of at least one liquid outlet 111 can be the same as the setting height of the top of the cleaning member 20, that is, the setting height of the liquid outlet 111 can be flexibly set according to actual needs, and the liquid outlet 111 can be not directly opposite to the cleaning member 20, which can effectively prevent the cleaning member 20 from being directly thrown into the liquid outlet 111 by dirt, etc., and prevent the liquid outlet 111 from being blocked, thereby preventing the cleaning efficiency of the floor brush 100 from being affected. For example, in an embodiment in which the liquid spray mechanism 10 is provided with a plurality of liquid outlets 111, some of which are directly opposite to the cleaning member 20, and the remaining liquid outlets 111 can be located between the central axis of the cleaning member 20 and the top of the cleaning member 20. Even if the liquid outlet 111 directly opposite to the cleaning member 20 is blocked, the remaining liquid outlets 111 can still wet the cleaning member 20 and improve the cleaning effect of the floor brush 100.

[0101] It should be noted that, in the height direction of the floor brush 100, if the liquid outlet 111 is located below the central axis of the cleaning member 20, it is not conducive to the liquid sprayed from the liquid outlet 111 to wet the cleaning member 20; if the liquid outlet 111 is located above the top of the cleaning member 20, the thickness of the floor brush 100 is increased, the processing cost is increased, and the liquid may not be sprayed to the cleaning member 20. In the height direction of the floor brush 100, the liquid outlet 111 is located between the center line of the cleaning member 20 and the top of the cleaning member 20, which can form a waterfall-like water spray and wet the cleaning member 20. By reasonably setting the distance between the liquid outlet 111 and the axis of the cleaning member 20 in the height direction of the floor brush 100, the volume of the floor brush 100 can be reduced, and the space resource occupation of the floor brush 100 can be reduced.

[0102] By setting the liquid outlet 111 as a strip-shaped outlet, the length of the coverage area of ​​the liquid sprayed from the liquid outlet 111 on the cleaning member 20 can be effectively increased, so that the cleaning member 20 can be wetted more quickly, thereby improving the user experience, and more evenly wetting the cleaning member 20, thereby avoiding uneven wetting due to point-like water spraying, or the inability to completely wet the cleaning member 20, thereby avoiding affecting the cleaning effect of the floor brush 100.

[0103] Please continue to see Figure 8-Figure 10 As shown, in some embodiments of the present invention, the spraying portion 119 is formed with a first flow channel 1194, and the first flow channel 1194 connects the liquid flow channel 114 and the liquid outlet 111. Specifically, the liquid can flow into the liquid flow channel 114 from the liquid inlet 113, and then flow out from the liquid outlet 111 after passing through the first flow channel 1194 to wet the cleaning member 20. The liquid flowing into the liquid inlet 113 can flow out from the liquid storage tank 202 of the cleaning device 200.

[0104] Please continue to see Figure 8As shown, in some embodiments of the present invention, the first flow channel 1194 extends obliquely upward from the body 118 to the spraying portion 119. Specifically, the first flow channel 1194 can connect the liquid flow channel 114 with the liquid outlet 111. The direction in which the first flow channel 1194 extends obliquely can be the direction in which the liquid flows. The direction in which the liquid flows can be Figure 8 The direction indicated by the dotted arrow is arranged so that the liquid can quickly flow into the liquid outlet 111, thereby effectively improving the flow rate of the liquid.

[0105] Please continue to see Figure 8 As shown, in some embodiments of the present invention, the assembly groove 1191 is connected to the liquid flow channel 114. This arrangement is to improve the utilization rate of the assembly groove 1191, so that the assembly groove 1191 can be used to install the spray part 119, and can also cooperate with the liquid flow channel 114 to transport liquid to the liquid outlet 111.

[0106] Please continue to see Figure 6-Figure 10 As shown, in some embodiments of the present invention, the body portion 118 includes: a first body 115 and a second body 116, the first body 115 and the second body 116 are connected and jointly define a liquid flow channel 114, and the second body 116 is provided with a liquid inlet 113. Specifically, the spraying portion 119 may include a third body 117. The first body 115, the second body 116, and the third body 117 are arranged along the front-to-back direction or the width direction of the spraying mechanism 10, and the width direction of the spraying mechanism 10 can be Figure 6 The first body 115 is connected between the second body 116 and the third body 117. The first body 115 and the third body 117 can be sealed by a sealing strip 120. The extension direction of the sealing strip 120 can be the same as the extension direction of the third body 117. Optionally, the sealing strip 120 can be configured to be U-shaped with an opening toward the third body 117. Such an arrangement can improve the structural stability and sealing of the liquid spraying mechanism 10. In addition, the main body 118 can be assembled from multiple parts, which is helpful for mold processing and reduces manufacturing difficulty and cost.

[0107] In some embodiments of the present invention, the body 118 may be provided with a liquid inlet 113, and a plurality of first flow channels 1194 may be formed in the body 118, and the first flow channels 1194 may connect the liquid inlet 113 and the liquid outlet 111, and the liquid may flow from the liquid inlet 113 to the liquid outlet 111 through the first flow channels 1194 to achieve a wetting effect on the cleaning member 20. It should be noted that the first flow channels 1194 may directly connect the liquid inlet 113 and the liquid outlet 111, or may indirectly connect the liquid inlet 113 and the liquid outlet 111, and the embodiments of the present invention do not impose any special restrictions.

[0108] Furthermore, the plurality of first flow channels 1194 are spaced apart in the axial direction of the cleaning member 20, so that the liquid sprayed from the liquid outlet 111 covers a wider range and can more evenly wet the cleaning member 20. In addition, each liquid outlet 111 is in communication with at least one first flow channel 1194, that is, each liquid outlet 111 can be in communication with a first flow channel 1194 or with a plurality of first flow channels 1194. In some embodiments, each liquid outlet 111 is in communication with a plurality of first flow channels 1194, so that the liquid supply of the liquid outlet 111 is more sufficient, and the liquid can fully contact the cleaning member 20, thereby achieving a good wetting effect.

[0109] In some specific embodiments of the present invention, a liquid flow channel 114 may be formed in the liquid spray body 11, and the liquid flow channel 114 connects the liquid inlet 113 and the first flow channel 1194. During operation, the liquid flows from the liquid inlet 113 to the liquid flow channel 114, and then flows to the liquid outlet 111 through the first flow channel 1194. Thus, the liquid flow channel 114 can form a buffer channel between the liquid inlet 113 and the liquid outlet 111, which has a confluence effect, thereby improving the uniformity and stability of the liquid discharged from the liquid outlet 111.

[0110] In addition, the first body 115 and the second body 116 can be ultrasonically welded to ensure the seal between the first body 115 and the second body 116, the first body 115 and the third body 117 can be glued to ensure the seal between the first body 115 and the third body 117, and a sealing strip 120 can be provided between the first body 115 and the third body 117 to achieve a better sealing effect. The liquid outlet 111 can be defined by the third body 117 alone, or the liquid outlet 111 can be defined by the first body 115 and the third body 117 in cooperation.

[0111] In an embodiment in which the first body 115 and the third body 117 cooperate to define the liquid outlet 111, the top wall of the first body 115 is the top of the liquid spraying mechanism 10, and the upper end of the third body 117 is formed with the liquid outlet 111, the upper end of the liquid outlet 111 is open, and the top wall of the first body 115 blocks the upper end of the liquid outlet 111. Such a setting can facilitate the processing of the liquid outlet 111 on the liquid spraying mechanism 10, reduce the processing difficulty, and improve the processing efficiency.

[0112] Further, more specifically, combined with Fig. 9 and Fig.10As shown, a third channel 1196 extending in the left-right direction is constructed on the inner surface of the second body 116, and the third channel 1196 is connected to the liquid inlet 113. The third channel 1196 can guide the liquid entering from the liquid inlet 113 to both sides of the liquid inlet 113, so that the liquid can quickly fill the interior of the liquid spraying mechanism 10. A plurality of second flow channels 1195 are arranged at intervals on the first body 115, and the plurality of second flow channels 1195 and the third channel 1196 together form a liquid flow channel 114. Optionally, a first flow channel 1194 is arranged on the third body 117, and the first flow channel 1194 connects the liquid flow channel 114 and the liquid outlet 111 to guide the liquid in the liquid flow channel 114 to the liquid outlet 111.

[0113] In some embodiments of the present invention, an infusion groove (not shown in the figure) can be constructed on the end face of the top of the third body 117, and the infusion groove is constructed as a liquid outlet 111. The liquid outlet 111 can guide the liquid flowing out of the first flow channel 1194 to form a waterfall-like water spray, thereby achieving a confluence effect, improving the uniformity of water output, and thereby improving the wetting effect of the liquid and the cleaning element 20.

[0114] In other embodiments of the present invention, multiple infusion tanks may be provided, and the multiple infusion tanks may be arranged at intervals, and the multiple liquid outlets are all connected to the first flow channel 1194, so that the uniformity of liquid spraying can be ensured as much as possible while saving water.

[0115] In some embodiments of the present invention, the housing of the mounting seat 30 may define a suction channel 31, but the present invention is not limited thereto. For example, in some other embodiments of the present invention, the suction channel 31 is defined by a separate component, and the component defining the suction channel 31 is mounted on the mounting seat 30. The suction channel 31 may be a surface near the suction port (and the communication port 37).

[0116] Please continue to see Figure 5 and Figure 11-Figure 14 As shown, in some embodiments of the present invention, the floor brush 100 further includes: a liquid spraying member 70, which is used to spray liquid toward the inner side wall 32 of the suction channel 31. Specifically, the liquid spraying member 70 can be arranged on the mounting seat 30. Among them, at least part of the structure of the liquid spraying member 70 can be arranged to extend into the mounting seat 30 to reduce the space occupied by the liquid spraying member 70 in the suction channel 31, thereby reducing the interference of the airflow in the suction channel 31 during the flow. In addition, by arranging the liquid spraying member 70 on the mounting seat 30, the floor brush 100 can automatically control the liquid spraying member 70 to clean the suction channel 31 during normal operation, and the user does not need to frequently disassemble the liquid spraying member 70, which can reduce the difficulty of cleaning the suction channel 31, and can also increase the frequency of the floor brush 100 cleaning the suction channel 31, thereby keeping the suction channel 31 clean and tidy.

[0117] Furthermore, there may be a plurality of liquid spraying members 70, and the plurality of liquid spraying members 70 may be spaced apart in the width direction of the floor brush 100. Figure 5 The direction indicated by Y in the figure. Preferably, in the width direction of the floor brush 100, a plurality of liquid spraying members 70 can be symmetrically arranged on both sides of the mounting seat 30, and a plurality of liquid spraying members 70 located on the same side of the floor brush 100 can spray in the same direction, and the liquid spraying directions of the liquid spraying members 70 on both sides of the mounting seat 30 are relatively arranged, so that the liquid spraying directions of the liquid spraying members 70 are all toward the inner wall 32, and the liquid sprayed by the liquid spraying members 70 can flow toward the inner wall 32, so that the floor brush 100 can more easily recover the liquid mixed with dust and other debris under the action of negative air pressure, and can avoid the accumulation of liquid in the suction channel 31, thereby further improving the use experience of the cleaning device 200.

[0118] Further, there may be two liquid spraying members 70, and in the width direction of the floor brush 100, the two liquid spraying members 70 may be respectively arranged near the two ends of the floor brush 100, and in the axial direction of the suction channel 31, the suction channel 31 has a first end near the cleaning member 20 and a second end away from the cleaning member 20, and the liquid spraying member 70 is arranged near the first end of the cleaning member 20. The liquid spraying member 70 is arranged near the first end of the cleaning member 20, so that the liquid spraying member 70 can flush a larger area of ​​the inner side wall 32 of the suction channel 31, thereby improving the cleanliness of the suction channel 31.

[0119] For further information, please see Figure 11-Figure 14 As shown, the liquid spraying member 70 may be provided with a liquid spraying port 71, and the liquid spraying member 70 may be provided in the mounting seat 30, and the liquid spraying port 71 extends out of the mounting seat 30 from the inner side wall 32 of the suction channel 31 to spray liquid toward the suction channel 31. Among them, at least part of the structure of the liquid spraying member 70 may extend into the suction channel 31, and the liquid spraying port 71 is located in the part of the structure of the liquid spraying member 70 extending into the suction channel 31. By making the liquid spraying port 71 extend out of the mounting seat 30, the liquid spraying member 70 may be prevented from spraying liquid into the mounting seat 30, thereby preventing short circuit and burning of electronic parts in the mounting seat 30, and also preventing liquid from accumulating in the mounting seat 30 and generating odor. Moreover, such a configuration can also make the liquid spraying direction of the liquid spraying member 70 toward the suction channel 31. After the liquid is sprayed out from the liquid spraying member 70, the liquid can drip onto the inner wall 32 of the suction channel 31, so that dust and other debris attached to the inner wall 32 of the suction channel 31 can be dropped from the inner wall 32 of the suction channel 31 under the action of water pressure, thereby preventing dust and other debris from accumulating in the suction channel 31.

[0120] For further information, please see Figure 12-14As shown, the liquid spraying member 70 may include: a liquid inlet body 72 and a liquid spraying body 73, the liquid inlet body 72 and the liquid spraying body 73 are connected, the liquid inlet body 72 defines a liquid inlet channel 721, the liquid spraying body 73 defines a liquid spraying port 71, and the liquid inlet channel 721 is connected with the liquid spraying port 71. The liquid inlet channel 721 may be extended along the axial direction of the liquid inlet body 72, and the liquid inlet channel 721 may penetrate the liquid inlet body 72, in the axial direction of the liquid inlet body 72, one end of the liquid inlet body 72 may be connected with the liquid spraying body 73, and the other end of the liquid inlet body 72 may be provided with a pipe joint (not shown in the figure), the liquid inlet body 72 may be connected with the liquid pipeline through the pipe joint, so that the liquid pipeline is connected with the liquid inlet channel 721, the liquid in the liquid pipeline may flow to the liquid spraying body 73 through the liquid inlet channel 721, and then the liquid may be sprayed from the liquid spraying port 71 to the inner side wall 32 of the suction channel 31.

[0121] By separately arranging the liquid inlet body 72 and the liquid spray body 73, the assembler can first install the liquid spray body 73 on the mounting seat 30, and then connect the liquid spray body 73 with the liquid inlet body 72, thereby reducing the difficulty of assembling the liquid spray body 73 and the liquid inlet body 72, thereby improving the production efficiency of the floor brush 100, and when the liquid spray component 70 is partially damaged, the maintenance personnel can repair the liquid spray component 70 by replacing the corresponding parts, thereby reducing the maintenance cost of the liquid spray component 70.

[0122] For further information, please see Fig.11 and Fig.12 As shown, the inner side wall 32 of the suction channel 31 may be provided with an avoidance hole 33, and the end of the liquid spraying body 73 close to the inner side wall 32 of the suction channel 31 is formed with a liquid spraying port 71 and extends out of the mounting seat 30 from the avoidance hole 33. The avoidance hole 33 can avoid the liquid spraying body 73, so as to avoid the liquid spraying body 73 from interfering with the inner side wall 32 of the suction channel 31, and the size and shape of the avoidance hole 33 can be adapted to the circumferential outer contour of the liquid spraying body 73, so that the size of the gap between the circumferential outer side wall of the liquid spraying body 73 and the hole wall of the avoidance hole 33 can be reduced, and the liquid can be reduced from the gap between the circumferential outer side wall of the liquid spraying body 73 and the hole wall of the avoidance hole 33 into the mounting seat 30.

[0123] In some embodiments, in order to prevent the liquid spray body 73 from protruding too high on the surface of the inner wall 32 of the suction channel 31, part of the structure of the inner wall 32 of the suction channel 31 can be tilted inward. Such a configuration can make the end face of the liquid spray body 73 flush with the outer surface of the inner wall 32 of the suction channel 31, and at the same time make the liquid spray port 71 located in the suction channel 31, and the liquid spray port 71 can be open toward the inside of the suction channel 31, which can not only prevent the liquid spray body 73 from affecting the flow of air in the suction channel 31, but also make the position of the liquid spray port 71 in the suction channel 31 more concealed, thereby meeting the appearance design requirements of the floor brush 100.

[0124] Furthermore, if Fig.12 and Fig.13 As shown, the liquid spraying body 73 can be sleeved on the outside of the liquid inlet body 72 and further define a connecting channel 731, and the connecting channel 731 connects the liquid spraying port 71 and the liquid inlet channel 721. Among them, the connecting channel 731 can penetrate the liquid spraying body 73 along the axial direction of the liquid spraying body 73, and by making the liquid spraying body 73 suitable for sleeved on the outside of the liquid inlet body 72, the liquid spraying body 73 and the liquid inlet body 72 can be plugged and matched, so that the difficulty of connecting and matching between the liquid spraying body 73 and the liquid inlet body 72 can be reduced, thereby further improving the assembly efficiency of the floor brush 100. Of course, the embodiment of the present invention is not limited to this. For example, one of the liquid spraying body 73 and the liquid inlet body 72 can be provided with a nut, and the other of the liquid spraying body 73 and the liquid inlet body 72 can be provided with an external thread. Through the cooperation of the nut and the external thread, the liquid spraying body 73 and the liquid inlet body 72 can be reliably connected together. The liquid in the liquid pipeline can flow to the liquid spray port 71 through the liquid inlet channel 721 and the connecting channel 731 in sequence, thereby achieving the technical effect of spraying the liquid to the inner wall 32 of the suction channel 31 through the liquid spraying member 70 .

[0125] For further information, please see Fig.14 As shown, the liquid spray port 71 has a guide portion 734, which can guide the liquid flowing in the connecting channel 731 and change the flow direction of the liquid. The guide portion 734 can change the flow direction of the liquid toward Fig.11 The suction channel 31 of the middle mounting seat 30, so that when the liquid is sprayed out from the liquid spray port 71, the liquid can continue to flow toward the suction channel 31, which can reduce the air negative pressure required for the liquid to flow from the liquid spray port 71 to the suction channel 31, thereby reducing the operating power of the motor, and further reducing the working noise of the floor brush 100.

[0126] Furthermore, the liquid spraying body 73 and the liquid inlet body 72 can be anti-rotationally matched. In some specific embodiments, for example Fig.13As shown, the circumferential outer wall of the liquid spray body 73 and the circumferential outer wall of the liquid inlet body 72 can be constructed into an oblong shape. After the liquid spray body 73 and the liquid inlet body 72 are plugged into each other, it is difficult for the liquid inlet body 72 to rotate in the liquid spray body 73, thereby preventing the liquid from flowing out of the gap between the liquid spray body 73 and the liquid inlet body 72 when the liquid inlet body 72 rotates in the liquid spray body 73, thereby improving the sealing performance of the liquid spray component 70.

[0127] For further information, please see Fig.13 and Fig.14 As shown, a sealing member 733 may be provided in the gap between the liquid spraying body 73 and the liquid inlet body 72. Preferably, the sealing member 733 may be configured as a rubber ring. When the liquid spraying body 73 and the liquid inlet body 72 are plugged and matched, the liquid spraying body 73 and the liquid inlet body 72 may jointly squeeze the sealing member 733. After being squeezed, the sealing member 733 may seal the gap between the liquid spraying body 73 and the liquid inlet body 72, thereby further improving the sealing performance of the liquid spraying member 70. However, the present invention is not limited thereto. For example, the liquid spraying body 73 and the liquid inlet body 72 may be welded to seal the gap between the liquid spraying body 73 and the liquid inlet body 72. In other embodiments, the gap between the liquid spraying body 73 and the liquid inlet body 72 may be filled with a sealant to seal the gap between the liquid spraying body 73 and the liquid inlet body 72.

[0128] In some other embodiments of the present invention, the inner side wall 32 of the suction channel 31 is formed with a shielding portion protruding toward the inside of the suction channel 31, the shielding portion is used to shield the avoidance hole 33, and the shielding portion has a avoidance opening corresponding to the liquid spraying port 71. Among them, the shielding portion can define a liquid spraying space, at least part of the structure of the liquid spraying body 73 can extend into the liquid spraying space, and the liquid spraying port 71 can be located in the liquid spraying space, that is, the liquid spraying body 73 can spray liquid in the liquid spraying space. In addition, the avoidance opening on the shielding portion can be arranged opposite to the liquid spraying port 71, and when the liquid is sprayed from the liquid spraying port 71, the liquid can pass through the avoidance opening on the shielding portion and then spray into the suction channel 31. By setting a shielding portion in the suction channel 31, the shielding portion can reduce the opening size on the inner wall 32 of the suction channel 31, which is beneficial to sealing the gap between the liquid spray body 73 and the inner wall 32 of the suction channel 31, thereby reducing the probability of liquid entering the mounting base 30 from the avoidance hole 33, and further improving the working reliability of the floor brush 100.

[0129] Please continue to see Fig.13As shown, in some embodiments of the present invention, the liquid spraying member 70 may further include: a fixing frame 74, the fixing frame 74 defines a positioning space 741, a first positioning portion 742 is provided in the positioning space 741, a second positioning portion 732 is provided on the outer surface of the liquid spraying body 73, the liquid spraying body 73 is provided in the positioning space 741, and the first positioning portion 742 and the second positioning portion 732 are positioned and matched. Preferably, one of the first positioning portion 742 and the second positioning portion 732 can be configured as a positioning protrusion, and the other of the first positioning portion 742 and the second positioning portion 732 can be configured as a positioning groove, for example, the first positioning portion 742 can be configured as a positioning protrusion, and the second positioning portion 732 can be configured as a positioning groove, or the second positioning portion 732 can be configured as a positioning protrusion, and the first positioning portion 742 can be configured as a positioning groove.

[0130] The positioning protrusion is suitable for extending into the positioning groove, and by interfering the positioning protrusion with the positioning groove, the first positioning portion 742 and the second positioning portion 732 are positioned and matched to limit the relative movement between the fixing frame 74 and the liquid spraying body 73. In addition, the fixing frame 74 can be fixed in the mounting seat 30, so that the fixing frame 74 can fix the liquid spraying body 73 to the mounting seat 30 by respectively connecting with the mounting seat 30 and the liquid spraying body 73, thereby preventing the liquid spraying member 70 from coming out of the avoidance hole 33, and further improving the product quality of the liquid spraying member 70.

[0131] For further information, please see Fig.11 and 12 As shown, the mounting seat 30 may also include: a positioning wall 36, which is arranged closer to the inner side of the mounting seat 30 than the inner side wall 32 of the suction channel 31, and the positioning wall 36 can be spaced apart from the inner side wall 32 of the suction channel 31, and the spacing distance between the positioning wall 36 and the inner side wall 32 of the suction channel 31 is adapted to the width dimension of the fixing frame 74. When the spray body 73 is pre-installed in the mounting seat 30, the installer can position and match the fixing frame 74 with the spray body 73, and the fixing frame 74 can be embedded between the positioning wall 36 and the inner side wall 32 of the suction channel 31. The positioning wall 36 cooperates with the inner side wall 32 of the suction channel 31 to limit the movement of the fixing frame 74 in the mounting seat 30, and then the fixing frame 74 can limit the movement of the spray body 73 in the mounting seat 30, thereby achieving the technical effect of fixing the spray part 70 to the mounting seat 30. However, the present invention is not limited thereto. For example, the fixing frame 74 may be provided with a connecting portion, and the connecting portion may be connected to the mounting seat 30 by a fastener. In some specific embodiments, the fastener may be a bolt.

[0132] In some embodiments of the present invention, Fig.12As shown, a sealing member 733 is sandwiched between the liquid spraying body 73 and the inner side wall 32 of the suction channel 31 to seal the avoidance hole 33. Preferably, the sealing member 733 can be constructed as a rubber ring, which can be sleeved on the outer side of the liquid spraying body 73. When the liquid spraying port 71 passes through the avoidance hole 33, the rubber ring can interfere with the inner side wall 32 of the suction channel 31, and the sealing member 733 is squeezed by the inner side wall 32 of the suction channel 31 and the liquid spraying body 73. After the sealing member 733 is pressed, it can seal the gap between the inner side wall 32 of the suction channel 31 and the liquid spraying body 73, so that the liquid in the suction channel 31 can be prevented from flowing from the gap between the inner side wall 32 of the suction channel 31 and the liquid spraying body 73 to the mounting seat 30, which can further prevent the electronic parts in the mounting seat 30 from being short-circuited and burned, and can also further prevent the liquid from accumulating in the mounting seat 30 and generating odor.

[0133] Please continue to see Fig.11 As shown, in some embodiments of the present invention, the liquid spraying member 70 is disposed in the suction channel 31 . Specifically, the liquid spraying member 70 is used to spray liquid toward the inner wall 32 of the suction channel 31. When dust and other debris move toward the suction channel 31, the dust and other debris can contact the inner wall 32 of the suction channel 31 of the suction channel 31, and some dust and other debris will adhere to the inner wall 32 of the suction channel 31 of the suction channel 31. The liquid sprayed by the liquid spraying member 70 toward the inner wall 32 of the suction channel 31 can be mixed with the dust and other debris attached to the inner wall 32 of the suction channel 31. Under the action of the negative pressure of air in the suction channel 31, the liquid sprayed by the liquid spraying member 70 can move on the inner wall 32 of the suction channel 31. The liquid can wash away the dust and other debris attached to the inner wall 32 of the suction channel 31, prevent the dust and other debris from clogging the suction channel 31, and avoid the occurrence of odor and other problems in the suction channel 31, thereby improving the user experience of the cleaning device 200 and further improving the market competitiveness of the cleaning device 200.

[0134] Please continue to see Figure 8 and Fig.11As shown, in some embodiments of the present invention, from the end of the suction channel 31 close to the cleaning member 20 to the end away from the cleaning member 20, the inner side wall 32 extends obliquely toward the inside of the suction channel 31. Specifically, in the width direction of the mounting seat 30, in order to make the air intake at both ends of the mounting seat 30 consistent, the structures of the suction channel 31 on both sides of the center line of the mounting seat 30 are symmetrically arranged. Therefore, by making the inner side wall 32 of the suction channel 31 extend obliquely toward the inside of the suction channel 31 from the end of the suction channel 31 close to the cleaning member 20 to the end away from the cleaning member 20, in the width direction of the mounting seat 30, the inner side wall 32 of the suction channel 31 can be obliquely connected between the connecting port 37 and the end of the mounting seat 30, so that the suction channel 31 can be constructed into a trumpet-shaped structure, and the inner side wall 32 of the suction channel 31 can guide the air in the suction channel 31. Such a setting can make the airflow flow more smoothly in the suction channel 31, thereby improving the effect of the floor brush 100 in sucking dust and other debris from the ground, and further improving the product quality of the floor brush 100.

[0135] Of course, in some other embodiments of the present invention, the inner side wall 32 of the suction channel 31 may also be arranged flush from the end of the suction channel 31 close to the cleaning member 20 to the end away from the cleaning member 20, so that the gap between the inner side wall 32 of the suction channel 31 and the cleaning member 20 can be reduced, thereby preventing dust and other debris from accumulating too much in the suction channel 31. Further, in the height direction of the mounting seat 30, the upper side wall and the lower side wall connected to the inner side wall 32 of the suction channel 31 can be arranged to extend obliquely toward the inside of the suction channel 31, so that the airflow can flow more smoothly in the suction channel 31, further improving the effect of the floor brush 100 in sucking dust and other debris from the ground.

[0136] Please continue to see Figure 3 and Figure 4 As shown, in some embodiments of the present invention, the floor brush 100 further includes: a scraper 40, which is disposed on the mounting seat 30 and is located between the liquid spraying mechanism 10 and the suction channel 31, and the end of the scraper 40 close to the cleaning member 20 contacts the cleaning member 20. Specifically, the scraper 40 can be disposed below the liquid spraying mechanism 10 along the height direction of the mounting seat 30, and the scraper 40 can extend along the axial direction of the cleaning member 20, and one end of the scraper 40 can abut against the cleaning member 20, and the other end of the scraper 40 away from the cleaning member 20 can be fixedly connected to the mounting seat 30. The scraper 40 and the cleaning member 20 can be in an interference fit relationship, and such a setting can remove dust, hair, sewage and other garbage attached to the surface of the cleaning member 20 through the scraper 40. At the same time, the scraper 40 can also cooperate with the mounting seat 30 to collect dust, hair, sewage and other garbage to the surface of the cleaning member 20. Figure 2 The waste is stored in the recovery box 201 of the cleaning device 200 .

[0137] In some embodiments of the present invention, the scraping member 40 is arranged on the mounting seat 30 and is located below the spray mechanism 10. The scraping member 40 extends toward the cleaning member 20 in a step-shaped manner in the height direction of the floor brush 100, and the end of the scraping member 40 close to the cleaning member 20 abuts or has an interference fit with the outer surface of the cleaning member 20. The scraping member 40 contacts the roller brush to squeeze out the sewage on the cleaning member 20 for suction, which is beneficial to improving the sewage recovery effect, can avoid residual water on the ground, and improve the cleaning effect.

[0138] It should be noted that the suction channel 31 can be separated from the liquid spraying mechanism 10, and a scraper member 40 can be provided between the suction channel 31 and the liquid spraying mechanism 10. When the cleaning member 20 rotates, the scraper member 40 can scrape off the liquid on the circumferential outer surface of the cleaning member 20, and the dirty liquid on the circumferential outer surface of the cleaning member 20 can flow into the suction channel 31. Under the action of the negative pressure of the air, the dirty liquid can be collected by the recovery box 201, thereby keeping the liquid spraying mechanism 10 clean and tidy.

[0139] Please continue to see Figure 3 and Figure 4 As shown, in some embodiments of the present invention, the floor brush 100 further includes: a liquid blocking member 50, which is arranged on the mounting seat 30 and located above the liquid spraying mechanism 10, and the end of the liquid blocking member 50 close to the cleaning member 20 contacts the cleaning member 20. Specifically, along the height direction of the mounting seat 30, the liquid blocking member 50 can be arranged above the liquid spraying mechanism 10, the liquid blocking member 50 and the scraping member 40 can be located on the upper and lower sides of the liquid spraying mechanism 10 respectively, the liquid blocking member 50 can extend along the axial direction of the cleaning member 20, and one end of the liquid blocking member 50 can abut against the cleaning member 20, and the other end of the liquid blocking member 50 away from the cleaning member 20 can be fixedly connected to the mounting seat 30. The liquid blocking member 50 and the cleaning member 20 can be in an interference fit relationship, and such an arrangement can effectively prevent the liquid sprayed by the liquid spraying mechanism 10 from overflowing through the liquid blocking member 50. At the same time, the liquid blocking member 50 can also evenly apply the liquid sprayed on the outer surface of the cleaning member 20.

[0140] Please continue to see Figure 1 and Figure 5 As shown, in some embodiments of the present invention, the floor brush 100 further includes: a driving member 60, which is connected to the cleaning member 20 to drive the cleaning member 20 to rotate. Specifically, the driving member 60 can be fixedly connected to the mounting seat 30, and the mounting shaft 35 of the driving member 60 can be connected to the end of the cleaning member 20. Exemplarily, the driving member 60 can be a driving motor, and such a configuration can drive the cleaning member 20 to rotate in a counterclockwise direction or a clockwise direction through the driving member 60.

[0141] In some embodiments of the present invention, the floor brush 100 also includes a hardware circuit (not shown in the figure) that can realize the forward and reverse control of the driving member 60, and the driving member 60 can be controlled by software to perform forward and reverse rotation, and then the driving member 60 drives the cleaning member 20 to rotate in the first direction or the second direction. When the floor brush 100 is placed on a charging base station (not shown in the figure) to start the self-cleaning operation, the charging base station may include an elastic scraper. When the floor scrubber is placed on the charging base, the elastic scraper can contact the surface of the cleaning member 20, and at the same time, the rotation direction of the cleaning member 20 can be controlled to be opposite to the rotation direction when the floor is conventionally cleaned.

[0142] The floor brush 100 may include the following steps when performing self-cleaning work:

[0143] The first stage: first, 100 floor brushes spray water, and the cleaning element 20 rotates forward; second, the fan starts to absorb water; then, 100 floor brushes spray water, and the cleaning element 20 rotates reversely; finally, the fan starts to absorb water.

[0144] The second stage: first, the floor brush 100 sprays water, the cleaning member 20 rotates forward, and the fan starts; secondly, the floor brush 100 sprays water, the cleaning member 20 rotates reversely, and the fan starts.

[0145] The third stage: first, only the fan is started, and the cleaning element 20 rotates forward; finally, the self-cleaning work of the floor brush 100 is completed.

[0146] It should be noted that in the above embodiment, the forward rotation direction of the cleaning member 20 can be the first direction or the second direction. For example, when the forward rotation is the first direction, the reverse rotation is the second reverse direction, and vice versa. Since the self-cleaning function of the floor brush 100 is already common on the market, competing products or the common practice in the industry is to use a roller brush to spray water and rotate in the same direction to perform the self-cleaning function. The sewage after self-cleaning is then sucked into the recycling bin. However, spraying water for self-cleaning in the same direction will cause dirt to accumulate on the water spray plate. If it is not cleaned for a long time, it will cause the machine to have a peculiar smell. Rotating in one direction for a long time will cause the roller brush hairs to be flattened, which is not conducive to the drying of the roller brush hairs. During the self-cleaning process of the floor brush 100 of the embodiment of the present invention, the cleaning member 20 is rotated forward and reversed, which can ensure that the liquid spray mechanism 10 is in a clean and tidy state for a long time, reduce user maintenance, and improve user experience.

[0147] Please continue to see Figure 3 and Figure 5As shown, in some embodiments of the present invention, the floor brush 100 further includes: a floor brush scraper bar 80, and a floor brush scraper bar 80 is provided at the lower end of the suction channel 31. The floor brush scraper bar 80 is arranged on the mounting seat 30 and is arranged corresponding to the cleaning member 20, and the floor brush scraper bar 80 extends downward and is suitable for interference fit with the ground. The floor brush scraper bar 80 can be used to scrape water to avoid residual water on the ground. From the above, when the floor brush 100 is placed on the surface to be cleaned (such as the ground), the cleaning member 20 and the scraping member 40, the floor brush scraper bar 80 and the ground construct a suction space, and the cleaning device 200 forms a negative pressure through a negative pressure motor, so that objects such as sewage and garbage are sucked into the recovery box 201 from the suction space and the suction channel 31, which can improve the cleaning effect.

[0148] Please continue to see Figure 2 and Fig.15 As shown, an embodiment of the present invention further provides a cleaning device 200, comprising: a floor brush 100, the floor brush 100 being the floor brush 100 in the above embodiment. A recycling box 201, the recycling box 201 being selectively connected to the suction channel 31 via a sewage channel 211. A liquid storage tank 202, the liquid storage tank 202 being connected to the liquid inlet 113 via a pipeline assembly (not shown in the figure). Among them, the recycling box 201 is used to recover a mixture of dust and other debris and liquid, the floor brush 100 can mix dust and other debris on the ground with liquid, and the floor brush 100 can suck the mixture of dust and other debris on the ground with liquid and guide it into the recycling box 201, so that the cleaning device 200 can remove dust and other debris on the ground.

[0149] In some embodiments, the recycling box 201 is detachably mounted on the cleaning device 200. When the recycling box 201 is full of a mixture of dust, other debris and liquid, or the user has finished cleaning the floor, the user can remove the recycling box 201 from the cleaning device 200 to empty the mixture of dust, other debris and liquid in the recycling box 201. In some other embodiments, the recycling box 201 may be provided with a drain port (not shown in the figure), and the user can open the drain port of the recycling box 201 to discharge the mixture of dust, other debris and liquid in the recycling box 201. Further, a one-way valve (not shown in the figure) may be provided between the recycling box 201 and the floor brush 100. The one-way valve can prevent the mixture of dust, other debris and liquid from flowing back from the recycling box 201 to the floor brush 100, thereby preventing the mixture of dust, other debris and liquid from being discharged from the floor brush 100 to the floor, and preventing the floor from being contaminated again.

[0150] Further, the liquid storage tank 202 is selectively connected to the liquid spraying member 70. The liquid storage tank 202 stores liquid for cleaning the floor. In some embodiments, the liquid stored in the liquid storage tank 202 is clean water. In other embodiments, the liquid stored in the liquid storage tank 202 is a detergent or clean water mixed with a detergent. In addition, a connecting valve 207 may be provided between the liquid storage tank 202 and the liquid spraying member 70. When the connecting valve 207 is opened, the liquid in the liquid storage tank 202 may flow to the liquid spraying member 70, so that the liquid spraying member 70 may spray the liquid to the inner side wall 32 of the suction channel 31 to remove dust and other debris attached to the inner side wall 32. The liquid storage tank 202 may also transport the stored liquid to the liquid spraying mechanism 10 of the floor brush 100. The liquid spraying mechanism 10 may evenly spray the liquid stored in the liquid storage tank 202 on the circumferential outer surface of the cleaning member 20, so that the cleaning member 20 may apply the liquid on the floor.

[0151] Furthermore, the cleaning device 200 may also include: a mounting rod 204 and a handle 203. The handle 203 and the floor brush 100 may be respectively installed at both ends of the mounting rod 204. The recovery box 201 and the liquid storage tank 202 may be both arranged on the outside of the mounting rod 204. The user may control the operation of the cleaning device 200 by operating the handle 203. The mounting rod 204 may extend the operating distance between the handle 203 and the floor brush 100, thereby making it easier for the user to operate the cleaning device 200 and improving the user experience of the cleaning device 200.

[0152] In some embodiments of the present invention, the cleaning device 200 may be a floor scrubber for cleaning sewage and stains on the surface of the floor waiting to be cleaned. The user can hold the handle 203 to control the floor brush 100, and can adjust the angle of the mounting rod 204 relative to the floor brush 100, flexibly adjust the cleaning posture, and enhance the user's experience. In addition, the floor brush 100 has a suction port (not shown in the figure), one end of the sewage channel 211 is connected to the recycling box 201, and the other end is connected to the suction port. When the vacuum mechanism in the cleaning device 200 is working, a negative pressure is formed in the sewage channel 211. Under the action of the negative pressure, sewage, dirt, etc. on the ground can be sucked in by the suction port and stored in the recycling box 201 through the sewage channel 211 to achieve the effect of cleaning the floor.

[0153] Furthermore, the liquid storage tank 202 in the cleaning device 200 can be connected to the liquid spraying mechanism 10 of the floor brush 100 through a supply pipeline, and the liquid storage tank 202 can contain detergent, clean water, or a mixture of clean water and detergent. During use, the liquid in the liquid storage tank 202 can flow to the liquid spraying mechanism 10 through the pipeline assembly and wet the cleaning element 20, so that the cleaning element 20 can more easily clean the sewage or dirt on the floor, and the cleaning effect that can be achieved is better.

[0154] In some specific embodiments, Fig.15 As shown, a water pump 205 and a solenoid valve 206 can be provided in the pipeline assembly, and the water pump 205 can effectively increase the flow rate of the liquid in the pipeline assembly, and the flow rate of the liquid increases in the same time, that is, the wetting effect of the cleaning element 20 is better, which is conducive to improving the cleaning effect of the cleaning device 200 and improving the user's experience. The solenoid valve 206 can effectively control the opening and closing state of the pipeline assembly, so as to cooperate with the water pump 205 to control the flow rate of the liquid.

[0155] According to the cleaning device 200 described in the embodiment of the present invention, by using the spray part 70 to spray liquid toward the inner wall 32 of the suction channel 31, the liquid sprayed by the spray part 70 can wash away the dust and other debris attached to the inner wall 32 of the suction channel 31, thereby preventing the dust and other debris from clogging the suction channel 31, and also avoiding the occurrence of problems such as odor in the suction channel 31, thereby improving the user experience of the cleaning device 200 and further improving the market competitiveness of the cleaning device 200.
