Description

[0001] A Floor Brush Structure and a Cleaning Device

[0002] Field of the Invention

[0003] The present invention relates to the technical field of cleaning means, and in particular, to a floor brush structure and a cleaning device.

[0004] Background of the Invention

[0005] A floor washer is a cleaning device that can be used to clean a hard floor while sucking dirty water off and bringing dirty water away from the site. A floor washer comprises a brush head and a body rotatably connected with the brush head. The body rotates relative to the brush head so as to be in an upright position or a non-upright position. Generally, when the floor washer is stopped, the body needs to be maintained in the upright position.

[0006] In prior art, the brush head has a position limiting slot while the main body has a locking tab. When the main body is in the upright position, the locking tab is snap-fitted in the position limiting slot so as to limit the main body’s rotation relative to the brush head, thereby preventing the main body from toppling over and maintaining the body in the upright position.

[0007] However, as such locking tab may easily detach from the position limiting slot, the stability of the body in the upright position is relatively poor.

[0008] Summary of the Invention

[0009] In view of this, the present invention provides a floor brush structure and a cleaning device to solve the shortcomings in the prior art.

[0010] In one aspect, the present invention provides a floor brush structure comprising a brush head, a main body connecting assembly and a locking mechanism, the main body connecting assembly comprising a connecting seat rotatably arranged at the brush head; the locking mechanism comprising a rotary member and a mobile member, the rotary member being rotatably connected with the connecting seat and used for connecting a main body of a cleaning device, the mobile member being arranged at the connecting seat and configured to: when the connecting seat rotates relative to the brush head to an upright position, partially insert into the rotary member so as to limit the relative rotation between the rotary member and the connecting seat; and, when the connecting seat rotates relative to the brush head to a non-upright position, detach from the rotary member so as to release the limitation on the relative rotation between the rotary member and the connecting seat. In the floor brush structure provided by the present invention, a brush head, a connecting seat and a rotary member are provided so that the connecting seat is rotatably connected with the brush head and the connecting seat rotates relative to the brush head to an upright position or to a non-upright position. The rotary member is rotatably connected with the connecting seat so as to rotate relative to the connecting seat. The mobile member is provided in the connecting seat so that when the connecting seat rotates relative to the brush head to the upright position, the mobile member is partially inserted into the rotary member, at which moment the mobile member secures the rotary member to the connecting seat so that relative rotation between the rotary member and the connecting seat is prevented. As the rotary member is connected with a main body of a cleaning device, the main body of the cleaning device cannot rotate relative to the connecting seat, so that the gravity center of the main body of the cleaning device does not easily shift, and the risk of the main body of the clean device to topple over is reduced, thereby resulting in a better stability.

[0011] In a possible mode of realization, in the floor brush structure provided by the present invention, the main body connecting assembly further comprises a mounting seat used for connecting the main body of the cleaning device, the rotary member being fixed with the mounting seat so that the mounting seat drives, via the rotary member, the connecting seat to rotate relative to the brush head.

[0012] Thus, by providing a mounting seat which connects the main body of the cleaning device and arranging the rotary member on the mounting seat, the connection between the rotary member and the main body of the cleaning device is facilitated.

[0013] In a possible mode of realization, in the floor brush structure provided by the present invention, the locking mechanism further comprises a driving assembly, the mobile member being inserted in the connecting seat, the driving assembly driving the mobile member to partially insert into the rotary member or detach from the rotary member.

[0014] Thus, when the connecting seat rotates relative to the brush head to the upright position, the driving assembly drives the mobile member to be partially inserted into the rotary member, whereas when the connecting seat rotates relative to the brush head to a non-upright position, the driving assembly drives the mobile member to detach from the rotary member, thereby controlling the insertion of the mobile member into or detachment from the rotary member by means of the driving assembly.

[0015] In a possible mode of realization, in the floor brush structure provided by the present invention, the locking mechanism further comprises a fixing support arranged at the connecting seat, the mobile member being inserted in the fixing support. By inserting the mobile member in the fixing support, the connection of the mobile member with the connecting seat is facilitated. At the same time, the fixing support can guide the movement of the mobile member, thereby facilitating the insertion of the mobile member into or detachment from the rotary member.

[0016] In a possible mode of realization, in the floor brush structure provided by the present invention, a mounting chamber is provided in the connecting seat, the mobile member being inserted in the mounting chamber, an end face of the connecting seat facing the rotary member having a first passage hole in communication with the mounting chamber, part of the mobile member passing into and out of the mounting chamber via the first passage hole.

[0017] Thus, the position of the mobile member is limited by means of the mounting chamber, so that the mobile member can only move along the mounting chamber. Further, the mobile member is guided by means of the first passage hole, so as to facilitate the insertion of the part of the mobile member into the rotary member when it extends out of the mounting chamber.

[0018] In a possible mode of realization, in the floor brush structure provided by the present invention, the driving assembly comprises a spring located in the mounting chamber and sleeved to the mobile member, and a position limiting member located on the brush head; the mobile member is configured to, when the connecting seat rotates relative to the brush head to the upright position, abut against the position limiting member and compress the spring so as to extend out of the mounting chamber via the first passage hole; or, when the connecting seat rotates relative to the brush head to detach from the position limiting member, be driven by a restoring force of the spring so as to return to the mounting chamber via the first passage hole.

[0019] Thus, when the connecting seat rotates relative to the brush head to the upright position, the mobile member is pushed to move towards the first passage hole by means of the position limiting member, thereby causing the mobile member to partially extend out of the mounting chamber via the first passage hole. When the connecting seat rotates relative to the brush head to a non-upright position, the mobile member is pushed to move towards the end of the mounting chamber away from the first passage hole by means of the return force of the spring, thus causing the part of the mobile member to return to the mounting chamber via the first passage hole.

[0020] In a possible mode of realization, in the floor brush structure provided by the present invention, the mobile member comprises a first rod, a support rod and a second rod that are sequentially arranged, the first rod being oriented towards the first passage hole, projections of both the first rod and the second rod towards the support rod being within the support rod, the spring being sleeved to the first rod and abutting against the support rod; the fixing support having a second passage hole, the second rod being inserted in the fixing support through the second passage hole.

[0021] Thus, when the first rod extends out of the mounting chamber through the first passage hole, part of it is inserted into the rotary member, thus part of the mobile member being inserted into the rotary member. When the second rod is inserted through the second passage hole, the mobile member is inserted into the fixing support. As the spring is compressed by the support rod when the connecting seat is in the upright position, when the connecting seat rotates relative to the brush head to a non-upright position, the spring has a restoring force. The second passage hole is used for guiding the mobile member. At the same time, the first passage hole and the second passage hole can prevent the support rod from extending out of the mounting chamber and thus prevent the first rod and the second rod from entirely extending out of the mounting chamber, thereby limiting the position of the first rod and the second rod.

[0022] In a possible mode of realization, in the floor brush structure provided by the present invention, the side of the rotary member facing the connecting seat has a mounting hole, the mobile member being partially inserted into the mounting hole or detached from the mounting hole.

[0023] Thus, the mobile member is guided by the mounting hole, so as to facilitate the insertion of part of the mobile member into the rotary member.

[0024] In a possible mode of realization, in the floor brush structure provided by the present invention, the rotary member comprises a first mounting part and a second mounting part, the first mounting part and the second mounting part being assembled to form a ring, an inner side wall of the ring having an annular groove; the connecting seat having a mounting ring arranged to be snap-fit in the annular groove.

[0025] Thus, the mounting rig can rotate relative to the annular groove, thereby enabling the connecting seat to rotate relative to the rotary member.

[0026] In a possible mode of realization, in the floor brush structure provided by the present invention, the connecting seat has a first articulation part, and the brush head has a second articulation part, the first articulation part and the second articulation part being articulated.

[0027] Thus, by means of the articulation formed between the first articulation part and the second articulation part, the first articulation part can rotate relative to the second articulation part, thereby enabling the connecting seat to rotate relative to the brush head.

[0028] In a possible mode of realization, in the floor brush structure provided by the present invention, the side of the rotary member facing away from the connecting seat is provided with at least two first connectors, the rotary member being inserted in the connecting seat with the first connectors connected with the mounting seat.

[0029] Thus, the rotary member is fixedly connected with the mounting seat by means of the connection between the mounting seat and each first connector.

[0030] In a possible mode of realization, in the floor brush structure provided by the present invention, the fixing support is provided with at least two second connectors and is inserted in the connecting seat with the second connectors connected with the connecting seat.

[0031] Thus, the fixing support is fixedly connected with the connecting seat by means of the connection between the connecting seat and each second connector.

[0032] In another aspect, the present invention provides a cleaning device comprising a device body and any above-described floor brush structure connected with the device body.

[0033] In addition to the technical problems solved by the embodiments of the present invention, the technical features that constitute the technical solutions, and the beneficial effects brought about by the technical features of these technical solutions that have been described above, other technical problems that can be solved by the floor brush mechanism and cleaning device provided by the present invention, other technical features included in the technical solutions, and the beneficial effects brought about by these technical features will be further described in detail in the detailed description of the invention.

[0055] Detailed Description of the Invention In order to make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be described in more detail below in conjunction with the accompanying drawings of preferred embodiments of the present invention. Throughout the accompanying drawings, the same or similar references represent the same or similar parts or parts with the same or similar functions. The described embodiments are some of the embodiments of the present invention, not all of the embodiments. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person of ordinary skills in the art without creative labor are within the scope of protection of the present invention. Embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0056] It should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms “mounted,” “connected,” and “connect” should be understood in a broad sense. For example, a connection can be a fixed connection, or an indirect connection through an intermediary, or an internal communication between two members or an interaction relationship between two members. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0057] It should also be noted that, in the description of the present invention, the terms indicating an orientation or position relationship, such as “upper,” “lower,” “front,” “back,” “vertical,” “horizontal,” “top,” “bottom,” “inner,” and “outside”, should be understood based on the orientation or position relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, instead of indicating or implying that the referred means or member must have a specific orientation, or constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present invention.

[0058] The terms “first,” “second,” and “third” (if any) in the specification, claims, and the above-described accompanying drawings of the present invention are used for distinguishing similar objects and are not necessarily used for describing a particular order or sequence. It should be understood that items thus used can be interchanged in appropriate circumstances so that the embodiments of the present invention described herein can be realized in an order other than what is illustrated or described.

[0059] In addition, the terms “comprise” and "have" and any variations thereof are intended to cover a non-exclusive inclusion. For example, a process, method, system, product, or display comprising a series of steps or members is not necessarily limited to those steps or members explicitly listed, but may include other steps or members not explicitly listed or inherent to such process, method, product, or display.

[0060] In prior art, a brush head may have a position limiting slot while a main body has a locking tab. When the body rotates relative to the brush head to an upright position, the locking tab slides into the position limiting slot and is snap-fitted with the position limiting slot so as to limit the main body’s rotation relative to the brush head, thereby maintaining the main body in the upright position and preventing the body from toppling over.

[0061] However, after the locking tab slides into the position limiting slot, the locking tab may easily detach from the position limiting slot. As the main body is relatively heavy, the detachment of the locking tab from the position limiting slot will result in a rotation of the main body relative to the brush head. Therefore, the center of gravity of the main body may easily shift, which may cause the body to topple over. The stability of the body in the upright position is poor.

[0062] In view of the above-described problem, the present invention provides a floor brush structure and a cleaning device. The floor brush structure comprises a brush head, a main body connecting assembly comprising a connecting seat rotatably arranged at the brush head, and a locking mechanism. The locking mechanism comprises a rotary member rotatably connected with the connecting seat and used for connecting a main body of a cleaning device, and a mobile member arranged at the connecting seat and configured to, when the connecting seat rotates relative to the brush head to the upright position, partially insert into the rotary member so as to limit relative rotation between the rotary member and the connecting seat, thereby preventing the main body of the cleaning device from rotating relative to the connecting seat. Thus, the center of gravity of the main body of the cleaning device cannot easily shift, reducing the risk of the main body of the cleaning device to topple over and resulting in a better stability.

[0063] Specific modes of realization of the floor brush structure and cleaning device provided by embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0064] In reference to Figs. 1 to 11 , the floor brush structure provided by an embodiment of the present invention comprises a brush head 100, a main body connecting assembly 200 and a locking mechanism 300. The main body connecting assembly 200 comprises a connecting seat 210 rotatably arranged at the brush head 100.

[0065] The locking mechanism 300 comprises a rotary member 310 and a mobile member 320. The rotary member 310 is rotatably connected with the connecting seat 210 and used for connecting a main body of a cleaning device. The mobile member 320 is arranged at the connecting seat 210 and configured to: when the connecting seat 210 rotates relative to the brush head 100 to an upright position, partially insert into the rotary member 310 so as to limit the relative rotation between the rotary member 310 and the connecting seat 210; or, when the connecting seat 210 rotates relative to the brush head 100 to a non-upright position, detach from the rotary member 310 so as to release the limitation on the relative rotation between the rotary member 310 and the connecting seat 210.

[0066] Specifically, the connecting seat 210 is capable of rotating forward and backward relative to the brush head 100. Thus, the angle between the connecting seat 210 and the brush head 100 can be adjusted so as to facilitate pushing the brush head 100. The connecting seat 210 can rotate relative to the rotary member 310, so as to drive the brush head 100 to rotate relative to the rotary member 310. Thus, the brush head 100 can rotate relative to the floor, thus adjusting the floor cleaning direction of the brush head 100.

[0067] When the brush head 100 has finished cleaning, the connecting seat 210 should be rotated relative to the brush head 100 to an upright position. Thus, when the cleaning device is not in use, the connecting seat 210 is stored in an upright position, which can save the storage space. An upright position means that an axis of the connecting seat 210 is perpendicular to the brush head 100.

[0068] It should be noted that, the connecting face between the rotary member 310 and the connecting seat 210 is an inclined face inclined relative to the brush head 100. As the main body of the cleaning device is relatively heavy, when the connecting seat 210 is in the upright position, if the rotary member 310 rotates relative to the connecting seat 210, the main body of the cleaning device may easily rotate relative to the connecting seat 210, too. Thus, the center of gravity of the main body of the cleaning device may shift, and the main body of the cleaning device may topple over, which may cause damage to the main body of the cleaning device.

[0069] In order to prevent the rotary member 310 from rotating relative to the connecting seat 210, the mobile member 320 is provided in the connecting seat 210. When the connecting seat 210 is in the upright position, part of the mobile member 320 is inserted into the rotary member 310 so as to limit the rotation of the rotary member 310 relative to the connecting seat 210 and thus prevent the main body of the cleaning device from toppling over. When the connecting seat 210 is in a non-upright position, the mobile member 320 detaches from the rotary member 310, and the limitation on relative rotation between the rotary member 310 and the connecting seat 210 is released, thereby allowing the connecting seat 210 to rotate relative to the rotary member 310. In the floor brush structure provided by the present invention, a brush head 100, a connecting seat 210 and a rotary member 310 are provided so that the connecting seat 210 is rotatably connected with the brush head 100 and the connecting seat 210 rotates relative to the brush head 100to an upright position or to a non-upright position. The rotary member 310 is rotatably connected with the connecting seat 210 so as to rotate relative to the connecting seat 210. The mobile member 320 is provided in the connecting seat 210 so that when the connecting seat 210 rotates relative to the brush head 100 to the upright position, the mobile member 320 is partially inserted into the rotary member 310 and secures the rotary member 310 to the connecting seat 210 so that relative rotation between the rotary member 310 and the connecting seat 210 is prevented. As the rotary member 310 is connected with a main body of a cleaning device, the main body of the cleaning device cannot rotate relative to the connecting seat 210, so that the gravity center of the main body of the cleaning device does not easily shift and the risk of the main body of the clean device to topple over is reduced, thereby resulting in a better stability.

[0070] In reference to Figs. 1 , 5, and 9, in some embodiments, the main body connecting assembly 200 further comprises a mounting seat 220 used for connecting the main body of the cleaning device. The rotary member 310 is fixed with the mounting seat 220 so that the mounting seat 220 drives, via the rotary member 310, the connecting seat 210 to rotate relative to the brush head 100.

[0071] It can be understood that the rotary member 310 is arranged in the mounting seat 220, with the periphery of the mounting seat 220 abutting against the periphery of the connecting seat 210.

[0072] Thus, by fixing the rotary member 310 with the mounting seat 220 and connecting the main body of the cleaning device via the mounting seat 220, the connection between the rotary member 310 and the main body of the cleaning device is facilitated.

[0073] In a possible mode of realization, the locking mechanism 300 further comprises a driving assembly. The mobile member 320 is inserted in the connecting seat 210. The driving assembly 320 drives the mobile member 310 to be partially inserted into the rotary member 310 or detach from the rotary member 310.

[0074] Thus, when the connecting seat 210 rotates relative to the brush head 100to the upright position, the driving assembly drives the mobile member 320 to be partially inserted into the rotary member 310, whereas when the connecting seat 210 rotates relative to the brush head 100 to a non-upright position, the driving assembly drives the mobile member 320 to detach from the rotary member 310, thereby controlling the insertion of the mobile member 320 into the rotary member 310 or detachment from the rotary member 310 by means of the driving assembly.

[0075] In reference to Fig. 9, in some embodiments, the locking mechanism 300 further comprises a fixing support 340 arranged at the connecting seat 210. The mobile member 320 is inserted in the fixing support 340.

[0076] Thus, by inserting the mobile member 320 in the fixing support 340, the connection of the mobile member 320 with the connecting seat 210 is facilitated. At the same time, the fixing support 340 can guide the mobile member 320, so as to facilitate the insertion of the mobile member 320 into the rotary member 310 or detachment from the rotary member 310.

[0077] In reference to Figs. 3, 4, 7, and 8, in a specific embodiment, a mounting chamber 211 is provided in the connecting seat 210. The mobile member 320 is inserted in the mounting chamber 211 . An end face of the connecting seat 210 facing the rotary member 310 has a first passage hole 212 in communication with the mounting chamber 211. Part of the mobile member 320 passes into and out of the mounting chamber 211 via the first passage hole 212.

[0078] It should be noted that, the end face of the connecting seat 210 facing the rotary member 310 abuts against a part of the rotary member 310, so that the mobile member 320 is inserted into the rotary member 310 once it extends out of the mounting chamber 211 via the first passage hole 212, and can detach from the rotary member 310 by returning to the mounting chamber 212 via the first passage hole 212.

[0079] Thus, when the connecting seat 210 rotates relative to the brush head 100 to an upright position, the mobile member 320 extends out of the mounting chamber 211 via the first passage hole 212 and thus partially inserts into the rotary member 310. When the connecting seat 210 rotates relative to the brush head 100 to a non-upright position, the mobile member 320 returns to the mounting chamber 211 via the first passage hole 212 and thus detaches from the rotary member 310.

[0080] Thus, the position of the mobile member 320 is limited by means of the mounting chamber 211 , so that the mobile member 320 can only move along the mounting chamber 211. Further, the mobile member 320 is guided by means of the first passage hole 212, so as to facilitate the insertion of the mobile member 320 into the rotary member 310 when it extends out of the mounting chamber.

[0081] In reference to Figs. 3, 7, and 9, in a possible mode of realization, the driving assembly comprises a spring 330 located in the mounting chamber 211 and sleeved to the mobile member 320, and a position limiting member 120 located on the brush head 100;

[0082] The mobile member 320 is configured to: when the connecting seat 210 rotates relative to the brush head 100 to the upright position, abut against the position limiting member 120 and compress the spring 330 t so as to extend out of the mounting chamber 211 via the first passage hole 212; or, when the connecting seat 210 rotates relative to the brush head 100 to detach from the position limiting member 120, be driven by a return force of the spring 330 so as to c to the mounting chamber 211 via the first passage hole 212.

[0083] In other words, when the connecting seat 210 rotates relative to the brush head 100 to the upright position, the end of the mobile member 320 away from the first passage hole 212 abuts against the position limiting member 120, which pushes the mobile member 320 to move towards the first passage hole 212, and partially extends out of the mounting chamber 211 via the first passage hole 212, thereby partially inserting into the rotary member 310. At the same time, the mobile member 320 drives the spring 330 to be compressed. When the connecting seat 210 rotates relative to the brush head 100 from the upright position to a non-upright position, the spring 330 tends to pass from a compressed state to an extended state. Under the elastic force of the spring 330, the mobile member 320 returns to the mounting chamber 211 via the first passage hole 212 so as to detach from the rotary member 310. At this moment, the position limiting member 120 detaches from the mobile member 320.

[0084] Thus, when the connecting seat 210 rotates relative to the brush head 100 to the upright position, the mobile member 120 is pushed to move towards the first passage hole 212 by means of the position limiting member 120, thereby causing the mobile member 320 to partially extend out of the mounting chamber 211 via the first passage hole 212. When the connecting seat 210 rotates relative to the brush head 100 to a non-upright position, the mobile member 320 is pushed to move towards the end of the mounting chamber 211 away from the first passage hole 212 by means of the return force of the spring 330, thus causing the mobile member 320 to return to the mounting chamber 211 via the first passage hole 212.

[0085] In reference to Figs. 4, 8, and 9, in some embodiments, the mobile member 320 comprises a first rod 321 , a support rod 322, and a second rod 323 that are sequentially arranged. The first rod 321 is oriented towards the first passage hole 212. Projections of both the first rod 321 and the second rod 3223 towards the support rod 322 are within the support rod 322. The spring 330 is sleeved to the first rod 321 and abuts against the support rod 322. The fixing support 340 has a second passage hole 341 . The second rod 323 being inserted into the fixing support 340 through the second passage hole 341 . In this embodiment, the first rod 321 , the support rod 322 and the second rod 323 are all in the shape of a circular cylinder. The diameter of the first rod 321 is smaller than that of the support rod 322. The first passage hole 212 matches the first rod 321 so as to allow the first rod 321 to extend out of the mounting chamber211 through the first passage hole 212, while preventing the support rod 322 from extending out of the mounting chamber 211 through the first passage hole 212. When the support rod 322 moves towards the first passage hole 212, the spring 330 is compressed between the first passage hole 212 and the support rod 322. The diameter of the second rod 323 is smaller than that of the support rod 322. The second passage hole 341 matches the second rod 323 and is in communication with the mounting chamber 211 , so as to allow the second rod 322 to extend through the second passage hole 341 to connect with the fixing support 340, while preventing the support rod 322 from extending out of the mounting chamber 211 through the second passage hole 341 .

[0086] Thus, when the first rod 321 extends out of the mounting chamber 211 through the first passage hole 212, part of it is inserted into the rotary member 310, thus part of the mobile member 320 is inserted into the rotary member 310. When the second rod 323 is inserted through the second passage hole 341 , the mobile member 320 is inserted into the fixing support 340. As the spring 330 is compressed by the support rod 322 when the connecting seat 210 is in an upright position, when the connecting seat 210 rotates relative to the brush head 100 to a non-upright position, the spring 330 has a return force. The second passage hole 341 is used for guiding the mobile member 320. At the same time, the first passage hole 212 and the second passage hole 341 can prevent the support rod 322 from extending out of the mounting chamber 211 and thus prevent the first rod 321 and the second rod 322 from entirely extending out of the mounting chamber 211 , thereby limiting the position of the first rod 321 and the second rod 323.

[0087] In reference to Figs. 4, 8, and 10, in a specific embodiment, the side of the rotary member 310 facing the connecting seat 210 has a mounting hole 311. The mobile member 320 partially inserts into the mounting hole 311 or detaches from the mounting hole 311 .

[0088] It should be noted that, before the connecting seat 210 rotates relative to the brush head 100 to the upright position, the connecting seat 210 should first be rotated relative to the rotary member 310 so that the mounting hole 311 and the mobile member 320 face each other, thus enabling the insertion of the mobile member 320 into the mounting hole 311 .

[0089] It should be understood that, the mobile member 320 is connected with the rotary member 310 by means of the insertion of the mobile member 320 into the mounting hole 311 , and the mobile member 320 detaches from the rotary member 310 by means of the disengagement of the mobile member 320 from the mounting hole 311 ,. Thus, as the mobile member 320 is guided by means of the mounting hole 311 , the insertion of the mobile member 320 into the rotary member 310 is facilitated.

[0090] In reference to Figs. 10 and 11 , in a possible mode of embodiment, the rotary member 310 comprises a first mounting part 312 and a second mounting part 313. The first mounting part 312 and the second mounting part 313 are assembled to form a ring, an inner side wall of the ring having a annular groove 314. The connecting seat 210 has a mounting ring 213 arranged to be snap-fit in the annular groove 314.

[0091] It should be understood that, when connecting the rotary member 310 with the connecting seat 210, the first mounting part 312 and the second mounting part 313 approach the mounting ring 213 respectively from two sides of the mounting ring 213 , until the first mounting part 312 and the second mounting part 313 abut against each other. Then, the first mounting part 312 and the second mounting part 313 are connected. At this moment, the first mounting part 312 and the second mounting part 313 are assembled with each other to form a ring, with the mounting ring 213 snap-fit in the annular groove 314.

[0092] In this embodiment, the first mounting part 312 and the second mounting part 313 are connected via snap-fit.

[0093] Thus, by snap-fitting the mounting ring 213 in the annular groove 314, the mounting ring 213 and the annular groove 314 are rotatably connected, so that the mounting ring 213 can rotate relative to the annular groove 314, thereby enabling the connecting seat 210 to rotate relative to the rotary member 310.

[0094] In reference to Figs. 9 and 11 , in some embodiments, the connecting seat 210 has a first articulation part 214, and the brush head 100 has a second articulation part 110. The first articulation part 214 and the second articulation part 110 are articulated.

[0095] Thus, by means of the articulation formed between the first articulation part 214 and the second articulation part 110, the first articulation part 214 can rotate relative to the second articulation part 110, thereby enabling the connecting seat 210 to rotate relative to the brush head 100.

[0096] In reference to Fig. 9, in a specific embodiment, the side of the rotary member 310 facing away from the connecting seat 210 is provided with at least two first connectors 315. The rotary member 310 is inserted into the connecting seat 220, with the first connectors 315 connected with the mounting seat 220.

[0097] Thus, the rotary member 310 can be fixedly connected with the mounting seat 220. By way of example, a floor brush structure provided by an embodiment of the present invention can further comprise a plurality of screws. The first connectors 315 are provided with first threaded holes. The mounting seat 220 is provided with at least two second threaded holes. Each screw is connected respectively with one of the second threaded holes and one of the first threaded holes, thus fixedly connecting the rotary member 310 with the mounting seat 220.

[0098] By way of example, four first connectors 315 are provided and spaced apart at the rotary member 310.

[0099] In reference to Fig. 9, in a specific embodiment, the fixing support 340 is provided with at least two second connectors 342 and is inserted into the connecting seat 210, with the second connectors 342 connected with the connecting seat 210.

[0100] Thus, the fixing support 340 can be fixedly connected with the connecting seat 210.

[0101] By way of example, a floor brush structure provided by an embodiment of the present invention further comprises a plurality of screws. The second connectors 342 are provided with third threaded holes. The fixing support 340 is provided with at least two fourth threaded holes. Each screw is connected respectively with one of fourth threaded hole and one of the third threaded holes, thereby fixedly connecting the fixing support 340 with the connecting seat 210.

[0102] By way of example, four second connectors 342 are provided and spaced apart at the fixing support 340.

[0103] Based on the above-described embodiments, the present embodiment provides a cleaning device comprising a device body and a floor brush structure connected with the device body.

[0104] The structure of the floor brush structure has been described in detail in the above-described embodiments, which are not described again here.

[0105] It should be noted that, the device body of the cleaning device comprises a main body.

[0106] In the cleaning device provided by the present invention, the connecting seat 210 and the rotary member 310 are provided in its floor brush structure. The connecting seat 210 can rotate relative to the brush head 100 to an upright position or a non-upright position. The rotary member 310 can drive the main body to rotate relative to the connecting seat 210. When the cleaning device is in a cleaning state, the connecting seat 210 is in a non-upright position, and when the cleaning device is not in a cleaning state, the connecting seat 210 is in the upright position. By providing the mobile member 320 at the connecting seat 210, when the cleaning device finishes cleaning, the connecting seat 210 is rotated relative to the brush head 100 to the upright position, at which moment, the mobile member 320 partially inserts into the rotary member 310 so as to prevent the relative rotation between the rotary member 310 and the connecting seat 210, thereby preventing the main body from rotating relative to the connecting seat 210 and from toppling over due to a shift of the center of gravity. Thus, with the cleaning device provided by the present invention, when the connecting seat 210 is placed in the upright position, the main body does not easily topple over, resulting in relatively good stability.

[0107] Finally, it should be noted that, the various embodiments above are merely used to describe the technical solutions of the present invention, instead of limiting it. Although the present invention has been described in detail with reference to the above-described embodiments, a person of ordinary skill in the art should understand that it is still possible to modify the technical solutions described in the above-described embodiments, or to make equivalent replacements for some or all of the technical features therein; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
