The terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used herein are only for the purpose of illustration and do not represent the only implementation.

[0045] As described in the background art, the roller brush driving member is assembled on the floating housing. When the floating housing floats relative to the fixed housing, the roller brush driving member can float relative to the fixed housing together with the floating housing. For traditional housings, dust easily flows from the outside to the roller brush driving member, resulting in dust deposition on the roller brush driving member. When a large amount of dust is deposited, it is likely to cause a failure of the roller brush driving member.

[0046] The inventors of the present application have found through research that the root cause of the above problems lies in that in order to ensure that the roller brush driving member can float together with the floating housing, that is, in order to ensure that the roller brush driving member has a floating space, generally an avoidance hole is provided on the fixed housing at a position corresponding to the roller brush driving member. When the floating housing floats relative to the fixed housing, the roller brush driving member can extend out of the avoidance hole of the fixed housing to float relative to the fixed housing. The above setting method causes external dust (such as the dust raised when the sweeping robot is sweeping the floor) to easily flow from the avoidance hole to the roller brush driving member and deposit on the roller brush driving member.

[0047] Referring to Figure 1 , an embodiment of the present invention provides a sweeping robot, which includes a roller brush mechanism 10 for collecting dust on the ground.

[0048] Specifically, the roller brush mechanism 10 includes a housing 11 and a roller brush (not shown in the figure). The housing 11 includes a fixed housing 111 and a floating housing 112, and the roller brush is assembled on the floating housing 112. Specifically in the embodiment, the floating housing 112 is provided with a roller brush cavity 1121 (refer to Figure 2 and Figure 3) The rotary brush is assembled in the rotary brush cavity 1121. The floating housing 112 is movably connected to the fixed housing 111 and can float relative to the fixed housing 111 under the action of an external force. It should be noted that the floating of the floating housing 112 relative to the fixed housing 111 means that the floating housing 112 can move up and down relative to the fixed housing 111. When the rotary brush encounters an obstacle during the operation of the floor cleaning robot, the floating housing 112 can drive the rotary brush to float upward to cross the obstacle; after crossing the obstacle, the floating housing 112 drives the rotary brush to float downward so that the rotary brush is in the working state.

[0049] Continue to refer to Figure 1 , the floating housing 112 includes a body 1122 and a rotating arm 1123. The rotary brush cavity 1121 is provided on the body 1122. One end of the rotating arm 1123 is connected to one side of the body 1122, and the other end is rotatably connected to the fixed housing 111. The floating housing 112 rotates relative to the fixed housing 111 through the rotating arm 1123, so that the floating housing 112 can float relative to the fixed housing 111 under the action of an external force. Specifically, the rotary brush mechanism 10 further includes a buffer member (not shown in the figure). In a direction intersecting the axial direction of the rotary brush, the rotating arm 1123 is connected to one side of the body 1122, one end of the buffer member is connected to the other side of the body 1122, and the other end of the buffer member is connected to the fixed housing 111. Through the above arrangement, when the floor cleaning robot is working, if the rotary brush encounters an obstacle, during the process of the floating housing 112 rotating relative to the fixed housing 111 through the rotating arm 1123, the floating housing 112 compresses the buffer member and drives the rotary brush to float upward to cross the obstacle. After crossing the obstacle, the buffer member elastically returns, and the floating housing 112 drives the rotary brush to float downward so that the rotary brush is in the working state.

[0050] Furthermore, the rotating arm 1123 includes two spaced apart along the extending direction of the floating housing 112 (the axial direction of the rotary brush). When the rotary brush is subjected to an external force, the floating housing 112 rotates relative to the fixed housing 111 through the two rotating arms 1123, and the buffer member elastically deforms and floats. In this way, when the floating housing 112 drives the rotary brush to float upward in a manner of compressing the buffer member, the other side of the floating housing 112 rotates relative to the fixed housing 111 through the two rotating arms 1123, so as to achieve the purpose of the overall upward floating of the floating housing 112 and the rotary brush. It should be understood that in other embodiments, the number of the rotating arms 1123 is not limited. For example, the rotating arm 1123 can also be more than two or one, as long as it can achieve the purpose that the floating housing 112 can rotate relative to the fixed housing 111 through the rotating arm 1123 when subjected to an external force.

[0051] Continue to refer to Figure 3, the floating housing 112 is further provided with a first opening 1124 communicating with the brush roller chamber 1121, and the buffer member is connected to one end of the floating housing 112 where the first opening 1124 is provided. The buffer member is provided with a first air flow chamber (not shown in the figure) penetrating therethrough, and the first air flow chamber communicates with the brush roller chamber 1121. The floor sweeping robot further includes a dust collection box (not shown in the figure) and an air duct assembly (not shown in the figure). The dust collection box communicates with the brush roller chamber 1121 through the first air flow chamber. The air duct assembly includes an air duct and a power member. The air duct communicates with the air outlet of the dust collection box, and the power member provides the power for the air flow to flow from the brush roller to the dust collection box.

[0052] The housing 11 further includes a brush roller cover (not shown in the figure). The brush roller cover is disposed on the floating housing 112, and a dust inlet (not shown in the figure) is provided on the brush roller cover. When the brush roller assembly works, dust from the outside is sucked in through the dust inlet. And when subjected to an external force, the brush roller cover can float with the floating housing 112 relative to the fixed housing 111.

[0053] The brush roller includes a roller body and a brush body, and the brush body is disposed on the surface of the roller body. Continuing to refer to Figure 1 , the floor sweeping robot further includes a brush roller driving member 13. An assembly position is provided on the main body 1122 of the floating housing 112, and the brush roller driving member 13 is assembled at the above-mentioned assembly position. Specifically, the above-mentioned assembly position is located on the side of the main body 1122 where the rotating arm 1123 is connected, so as to prevent the brush roller driving member 13 assembled at the assembly position from interfering with the arrangement of the dust collection box.

[0054] A relief hole (not shown in the figure) is provided on the fixed housing 111. When the floating housing 112 floats relative to the fixed housing 111, the brush roller driving member 13 can float up and down in the relief hole. That is to say, when the floating housing 112 floats relative to the fixed housing 111, the brush roller driving member 13 can penetrate out of or retract into the relief hole from the relief hole.

[0055] The roller body is connected to the brush roller driving member 13. The brush roller driving member 13 drives the roller body to rotate around its own axis, and then drives the brush body on the surface of the roller body to rotate. The rotating brush body contacts the ground to pick up dust and other garbage on the ground.

[0056] When the floor sweeping robot is working, the brush roller driving member 13 drives the roller body to rotate around its own axis, and then drives the brush body on the surface of the roller body to rotate. The rotating brush body contacts the ground to pick up dust and other garbage on the ground. At the same time, the power member operates, thereby generating a flowing air current. The flowing air current carries the dust picked up by the brush roller assembly into the dust collection box. The dust stays in the dust collection box, and the cleaning air current enters the air duct from the dust collection box and finally is discharged to the outside from the air duct. If the brush roller encounters an obstacle, when the floating housing 112 rotates relative to the fixed housing 111 through the rotating arm 1123, the floating housing 112 can drive the brush roller to float upward in a manner of compressing the buffer member to cross the obstacle. At this time, the brush roller driving member 13 floats in the relief hole.

[0057] In some embodiments, the buffer member is integrally injection-molded with the floating housing 112, and the buffer member is sleeved inside the floating housing 112. It should be understood that in some other embodiments, the buffer member and the floating housing 112 may not be integrally injection-molded. For example, in another embodiment, the housing 11 further includes a connecting member (not shown in the figure), the connecting member is integrally injection-molded with the buffer member, and the connecting member is connected to the floating housing 112. In a specific embodiment, the connecting member is connected to the floating housing 112 by screws. In another specific embodiment, the connecting member may also be connected to the floating housing 112 by snap-fitting, which is not limited herein. Therefore, the connection manner between the buffer member and the floating housing 112 is not limited herein either, as long as the connection manner can ensure the sealing effect at the connection between the buffer member and the floating housing 112 is within the protection scope of the present application.

[0058] In a specific embodiment, the buffer member is a flexible tube. Specifically, the flexible tube is a silicone tube. Of course, in some other embodiments, the specific structure and the material used for the buffer member are not specifically limited, as long as it can achieve the buffering effect and facilitate the flow of air.

[0059] Referring to Figure 4 and Figure 5 , in one embodiment, the housing 11 further includes a dust-proof housing 113. The dust-proof housing 113 is assembled on the fixed housing 111 and is configured to cooperate with the fixed housing 111 to form a floating cavity 1131, so as to accommodate at least a part of the roller brush driving member 13 that moves into through the floating hole when the floating housing 112 floats relative to the fixed housing 111. In this way, since the dust-proof housing 113 and the fixed housing 111 cooperate to form the floating cavity 1131, and at least a part of the roller brush driving member 13 can float in the floating cavity 1131 when the floating housing 112 floats relative to the fixed housing 111, external dust (dust on the side of the fixed housing 111 facing away from the floating housing 112) is not easily introduced into the roller brush driving member 13 through the avoidance hole, reducing the failure of the roller brush driving member 13 caused by dust deposition.

[0060] Specifically, the orthographic projection of the dust-proof housing 111 on the plane where the fixed housing 111 is located covers the avoidance hole to further reduce the entry of external dust into the roller brush driving member 13 through the avoidance hole.

[0061] Furthermore, the dust-proof housing 111 closes the avoidance hole, and the side of the dust-proof housing 113 facing away from the fixed housing 111 is recessed to form the floating cavity 1131 with the fixed housing 111, and at least a part of the roller brush driving member 13 floats in the floating cavity 1131. In this way, the dust-proof housing 113 closes the avoidance hole, which serves as the dust inlet of the roller brush driving member 13, so that external dust (dust on the side of the fixed housing 111 facing away from the floating housing 112) is not easily introduced into the roller brush driving member 13, reducing the failure of the roller brush driving member 13 caused by dust deposition.

[0062] Continue to refer to Figure 1 , specifically, the roller brush driving member 13 includes a motor 131 and a transmission member 132. The transmission member 132 is drivingly connected between the motor 131 and the roller brush. The motor 131 drives the roller brush to rotate through the transmission member 132, and the motor 131 can float within the floating cavity 1131 described above. It should be understood that in some other embodiments, the entire roller brush driving member 13 can also be set to float within the floating cavity 1131, which is not limited herein. More specifically, the transmission member 132 is a reduction gearbox, and a gear set is provided inside the reduction gearbox. The gear set is drivingly connected between the motor 131 and the roller brush.

[0063] The roller brush mechanism 10 further includes a wire 14. One end of the wire 14 is connected to the axial end face of the motor 131. The fixed housing 111 is provided with a through hole 1111. The wire 14 passes through the through hole 1111 and leads to the controller, and the controller controls the operation of the roller brush driving member 13. The through hole 1111 is provided on one side of the fixed housing 111 close to the floating housing 112 where the rotating arm 1123 is provided. With such a setting, when the floating housing 112 rotates relative to the fixed housing 111 through the rotating arm 1123, the bending angle of the wire 14 is smaller, thereby reducing the bending and breaking of the wire 14.

[0064] Since the through hole 1111 is provided on the fixed housing 111, external dust easily flows from the through hole 1111 to the roller brush driving member 13. Refer to Figure 6 and Figure 7 , the housing 11 further includes a dust-proof cover 114. The dust-proof cover 114 is assembled on the fixed housing 111 and closes the through hole 1111. The dust-proof cover 114 is provided with a wire passing hole 1141 (refer to Figure 3 ), and the wire 14 leads to the controller from the wire passing hole 1141. Among them, the orthographic projection of the wire passing hole 1141 on the plane where the fixed housing 111 is located is within the range of the orthographic projection of the through hole 1111 on the plane where the fixed housing 111 is located. With such a setting, the size of the wire passing hole 1141 is smaller than the size of the through hole 1111, and external dust is not easily flowed to the roller brush driving member 13 from the smaller-sized wire passing hole 1141.

[0065] The housing 11 further includes a sealing member (not shown in the figure). The sealing member is provided between the dust-proof cover 114 and the wire 14 to seal the gap between the wire 14 and the dust-proof cover 114, so as to further improve the dust-proof effect. The sealing member is detachably connected to the dust-proof cover 114, which is convenient for replacement when the sealing member is damaged.

[0066] In a specific embodiment, the dust-proof housing 113 is integrally formed with the fixed housing 111. With this arrangement, compared with the case where the dust-proof housing 113 and the fixed housing 111 are separately provided, there is no assembly gap between the dust-proof housing 113 and the fixed housing 111, and dust is not likely to flow towards the roller brush driving member 13. Further, the dust-proof cover 114 is assembled on the dust-proof housing 113, and the dust-proof cover 114, the dust-proof housing 113, and the fixed housing 111 are integrally formed. At this time, there is also no assembly gap between the dust-proof cover 114 and the dust-proof housing 113, which is convenient for dust prevention.

[0067] The dust-proof housing 113, the fixed housing 111, and the dust-proof cover 114 are all made of plastic material. Specifically, the dust-proof housing 113, the fixed housing 111, and the dust-proof cover 114 are made of ABS plastic, and the dust-proof housing 113, the fixed housing 111, and the dust-proof cover 114 are integrally injection-molded. Of course, in some other embodiments, the materials of the dust-proof housing 113, the fixed housing 111, and the dust-proof cover 114 are not limited.

[0068] It should be understood that in some other embodiments, the dust-proof housing 113 and the dust-proof cover 114 may also be separately provided from the fixed housing 111, which is not limited herein.

[0069] Continue to refer to Figure 4 In one embodiment, the housing 11 further includes a bottom cover 115. The bottom cover 115 is connected to the fixed housing 111, and the floating housing 112 is disposed between the bottom cover 115 and the fixed housing 111. The fixed housing 111, the floating housing 112, the dust-proof housing 113, and the bottom cover 115 together define a dust-proof cavity 16 including a floating cavity 1131. Through the above arrangement, dust is not likely to enter the roller brush driving member 13 from the bottom of the floor sweeping robot, ensuring the normal operation of the roller brush driving member 13. Further, a through hole 1151 is provided on the bottom cover 115, and the roller brush can pass through the through hole 1151 to contact the ground.

[0070] When the floor sweeping robot is working, the roller brush driving member 13 drives the roller body to rotate around its own axis, and then drives the brush body on the surface of the roller body to rotate. The brush body passes through the through hole 1151 to contact the ground and pick up dust and other garbage on the ground. At the same time, the power member acts to generate a flowing air current. The flowing air current carries the dust picked up by the roller brush assembly into the dust collection box. The dust stays in the dust collection box, and the cleaning air current enters the air duct from the dust collection box and finally discharges to the outside from the air duct. If the roller brush encounters an obstacle, the roller brush moves upward. The floating housing 112 receives the force applied to it by the roller brush through the roller brush driving member 13 and rotates relative to the fixed housing 111 through the rotating arm 1123. During the process of the floating housing 112 rotating relative to the fixed housing 111 through the rotating arm 1123, the floating housing 112 can drive the roller brush to float upward in a way of compressing the buffer member to cross the obstacle, and the roller brush driving member 13 can float in the dust-proof cavity 16.

[0071] An embodiment of the present invention further provides a roller brush mechanism 10 included in the above floor sweeping robot, and provides a housing 11 included in the above roller brush mechanism 10. For the above housing 11 and roller brush mechanism 10, since the dust-proof housing 113 and the fixed housing 111 cooperate to form a floating cavity 1131, at least a part of the roller brush driving member 13 can float in the floating cavity 1131 when the floating housing 112 floats relative to the fixed housing 111, so that external dust is not easily introduced into the roller brush driving member 13 through the avoidance hole, reducing the failures of the roller brush driving member 13 caused by dust deposition.

[0072] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.
