[0051] The invention will now be described in further detail with reference to the accompanying drawings, which will make the foregoing and other objects, features, aspects, and advantages of the invention more apparent, enabling those skilled in the art to practice it upon referring to the text of the specification. In the drawings, shapes and dimensions are enlarged for clarity, and the same reference numerals are used throughout the figures to indicate the same or similar parts.

[0052] Next, the present invention will be further described with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments. It should be understood that terms such as "having," "comprising," and "including" as used herein do not imply the presence or addition of one or more other elements or combinations thereof.

[0053] Combination Figures 1-11 The present invention relates to a floor brush mechanism 100, comprising: a floor brush body 110;

[0054] A roller brush 120 is rotatably mounted on the floor brush body 110, and the inside of the roller brush 120 is hollow to form a drive cavity 121;

[0055] A drive assembly 130 is mounted on the roller brush 120. The drive assembly 130 includes a roller driver 131 and a first connector 134 connected to each other. The roller driver 131 is fixed to the brush body 110 and is connected to the roller brush 120 to drive the roller brush 120 to rotate. The first connector 134 is located in the drive cavity 121.

[0056] Locking assembly 140 includes an unlocking knob 142 and a second connector 141. The second connector 141 is located inside the drive cavity 121, and at least a portion of the second connector 141 is sleeved on the outer periphery of the first connector 134 to limit the roller brush 120. At least a portion of the unlocking knob 142 is located inside the second connector 141.

[0057] Wherein, the maximum outer diameter of the portion of the unlocking knob 142 located inside the second connector 141 is greater than the inner diameter of the second connector 141, and the unlocking knob 142 can rotate under the drive of an external force, thereby causing the second connector 141 to expand to release the roller brush 120.

[0058] Understandably, in this invention, at least a portion of the second connector 141 is fitted around the outer periphery of the first connector 134, and the cooperation between the first connector 134 and the second connector 141 is used to axially fix the roller brush 120, thereby ensuring the stability of the roller brush 120 and enabling the roller brush 120 to work stably. At the same time, by driving the unlocking knob 142 to rotate through external force, the second connector 141 is expanded, so that the first connector 134 can be removed from the second connector 141 and the roller brush 120 can be released, or the first connector 134 can be partially embedded into the second connector 141 to fix the roller brush 120. This achieves convenient installation and removal of the roller brush 120, improves the convenience of installation and removal of the roller brush 120, and ultimately improves the removal efficiency of the roller brush 120.

[0059] Furthermore, combined again Figure 9 The second connector 141 includes: a fixing part 1411, the fixing part 1411 being mounted on the second end 123 of the roller brush 120; and

[0060] An extension 1412 is connected to the fixing part 1411 and located within the drive cavity 121;

[0061] The extension 1412 includes at least two circumferentially spaced snap-fit ​​strips 14121, and the inner diameter of the second connector 141 is the inner diameter of the circumference of the at least two snap-fit ​​strips 14121. The snap-fit ​​strips 14121 can deform under force.

[0062] In a preferred embodiment of the present invention, the fixing part 1411 and the extension part 1412 are integrally formed; or the fixing part 1411 and the extension part 1414 are fixedly connected.

[0063] Specifically, the connection method between the fixing part 1411 and the extension part 1412 can be selected by the staff according to the actual situation.

[0064] The snap-fit ​​strip 14121 is made of an elastic material so that the snap-fit ​​strip 14121 can deform under stress.

[0065] The specific material selection for the snap-fit ​​strip 14121 can be determined by the staff according to the actual situation, and is not specifically limited in this invention.

[0066] Specifically, the second connector 141 has two forms: a locked form and an unlocked form.

[0067] When at least a portion of the unlocking knob 142 is located inside the second connector 141, the latching strip 14121 is in a closed state, the unlocking knob 142 is in a locked position, and the second connector 141 is in a locked state.

[0068] When the unlocking knob 142 rotates under the action of external force to abut against the inner wall of the locking strip 14121, and at the same time, since the maximum outer diameter of the part of the unlocking knob 142 located inside the second connector 141 is greater than the inner diameter of the second connector 141, the locking strip 14121 deforms and changes from a closed state to an open state. The unlocking knob 142 is in the unlocked position, the second connector 141 is in the unlocked state, the first connector 134 can be partially embedded in the second connector 141, the unlocking knob 142 resets so that the second connector 141 returns to the locked state, and the first connector 134 cooperates with the second connector 141 to realize the limited installation of the roller brush 120;

[0069] Alternatively, the first connector 134 can be embedded in the second connector 141 and removed from the second connector 141 to disassemble the roller brush 120.

[0070] Furthermore, combined again Figures 4-8 The unlocking knob 142 has at least two protrusions 1421 in its circumferential area. The protrusions 1421 extend from the circumferential area of ​​the unlocking knob 142 in a direction away from the unlocking knob 142. The protrusions 1421 are distributed circumferentially at intervals. The maximum outer diameter of the unlocking knob 142 is the outer diameter of the circumference of at least two of the protrusions 1421.

[0071] A fixing groove 14122 is defined between two adjacent snap-fit ​​strips 14121, and the protrusion 1421 is arranged in the fixing groove 14122;

[0072] The protrusion 1421 can rotate under the drive of an external force and move from the fixing groove 14122 to abut against the inner wall of the snap-fit ​​strip 14121, so as to deform the snap-fit ​​strip 14121 and put it in an open state.

[0073] Specifically, when the protrusion 1421 is located in the fixing groove 14122, the snap-fit ​​strip 14121 is in a closed state, the unlocking knob 142 is in a locked position, and the second connector 141 is in a locked state.

[0074] Driven by an external force, the unlocking knob 142 rotates in one direction, causing the protrusion 1421 to rotate in the same direction. The protrusion 1421 moves from the fixing groove 14122 to abut against the inner wall of the snap-fit ​​strip 14121. At the same time, since the maximum outer diameter of the part of the unlocking knob 142 located inside the second connector 141 is greater than the inner diameter of the second connector 141, the snap-fit ​​strip 14121 deforms and changes from a closed state to an open state. The unlocking knob 142 is in the unlocked position, the second connector 141 is in the unlocked state, and the first connector 134 can be partially embedded in the second connector 141. The unlocking knob 142 resets so that the second connector 141 returns to the locked state. The first connector 134 cooperates with the second connector 141 to achieve the limited installation of the roller brush 120.

[0075] Alternatively, the first connector 134 can be embedded in the second connector 141 and removed from the second connector 141 to disassemble the roller brush 120.

[0076] In this invention, the unlocking knob 142 is driven to rotate by external force, which in turn drives the protrusion 1421 to rotate synchronously. The protrusion 1421 moves from the fixing groove 14122 to abut against the inner wall of the snap-fit ​​strip 14121, so that the snap-fit ​​strip 14121 deforms and changes from a closed state to an open state, thereby expanding the diameter of the circumference formed between the snap-fit ​​strips 14121. This ultimately facilitates the installation or removal of the roller brush 120 and improves the installation or removal efficiency of the roller brush 120.

[0077] In a preferred embodiment of the present invention, the protrusion 1421 is made of a flexible material; or the outer periphery of the protrusion 1421 is covered with an outer layer made of a flexible material, so that the protrusion 1421 and the locking strip 14121 are flexibly connected, which can effectively protect both of them, extend the service life of the unlocking knob 142 and the locking strip 14121, and reduce costs.

[0078] Furthermore, combined again Figure 8 An extension protrusion 14123 is provided on the inner wall of the snap-fit ​​strip 14121. The extension protrusion 14123 extends from the inner wall of the snap-fit ​​strip 14121 in a direction away from the snap-fit ​​strip 14121. In the axial direction of the roller brush 120, the extension protrusion 14123 corresponds to the position of the protrusion 1421.

[0079] Understandably, the present invention increases the expansion tendency of the snap-fit ​​strip 14121 by providing an expansion protrusion 14123 on the inner wall of the snap-fit ​​strip 14121. When the protrusion 1421 rotates under the drive of an external force to move from the fixing groove 14122 to abut against the inner wall of the snap-fit ​​strip 14121, the protrusion 1421 abuts against the expansion protrusion 14123, thereby increasing the opening degree of the snap-fit ​​strip 14121, further facilitating the installation or removal of the roller brush 120, and improving the installation or removal efficiency of the roller brush 120.

[0080] In a preferred embodiment of the present invention, the extended protrusion 14123 is made of a flexible material; or the outer periphery of the extended protrusion 14123 is covered with an outer layer made of a flexible material, so that the protrusion 1421 and the extended protrusion 14123 are flexibly connected, which can effectively protect both of them, extend the service life of the unlocking knob 142 and the locking strip 14121, and reduce costs.

[0081] In a specific embodiment of the present invention, again combined with Figures 5-7 The locking assembly 140 further includes a release knob 143 and a connecting rod 144. The release knob 143 is movably mounted on the fixing part 1411, and the first and last ends of the connecting rod 144 are fixedly connected to the unlocking knob 142 and the release knob 143, respectively.

[0082] The release knob 143 can be rotated under the drive of an external force, thereby driving the unlocking knob 142 to rotate, so as to cause the second connector 141 to expand and release the roller brush 120.

[0083] Specifically, the connecting rod 144 connects the release knob 143 and the unlocking knob 142 into a whole. When an external force is applied to the release knob 143, it drives the release knob 143 to rotate in one direction, and simultaneously drives the unlocking knob 142 to rotate in the same direction. The protrusion 1421 moves from the fixing groove 14122 to abut against the inner wall of the snap-fit ​​strip 14121, and the snap-fit ​​strip 14121 changes from a closed state to an open state, so as to realize the installation or removal of the roller brush 120.

[0084] In this invention, the release knob 143 is controlled synchronously with the unlocking knob 142 to facilitate the control of the unlocking knob 142, thereby facilitating the installation or removal of the roller brush 120.

[0085] In a preferred embodiment of the present invention, the external force may be provided by human or mechanical equipment, and no specific limitation is made in the present invention.

[0086] Furthermore, the fixing part 1411 is concave to form a receiving groove 14111, and the release knob 143 is arranged in the receiving groove 14111.

[0087] Understandably, by installing the release knob 143 in the receiving groove 14111, the overall structure is compact and occupies little space, while the second end 123 of the roller brush 120 can be completely flush with the edge, thereby improving the cleaning effect of the roller brush 120.

[0088] Furthermore, a reset element 145 is provided between the release knob 143 and the inner wall of the receiving groove 14111. The reset element 145 is any one of a torsion spring, an elastic sheet, or a bouncy ball.

[0089] Specifically, in one embodiment of the present invention, the reset element 145 is a torsion spring; in another embodiment of the present invention, the reset element 145 is an elastic sheet; and in yet another embodiment of the present invention, the reset element 145 is an elastic ball.

[0090] The specific selection of the reset element 145 can be made by the operator according to the actual situation, and no specific limitation is made in this invention.

[0091] In this invention, a reset element 145 is provided between the release knob 143 and the inner wall of the receiving groove 14111. When an external force is applied to the release knob 143, causing the release knob 143 to rotate in one direction, the reset element 145 deforms to generate a reset force. When the external force applied to the release knob 143 disappears, the reset element 145 returns to its original state under the action of the reset force, and the release knob 143 and the unlocking knob 141 are simultaneously reset under the action of the reset force.

[0092] In a specific embodiment of the present invention, again combined with Figure 5 Each of the snap-fit ​​strips 14121 has a first snap-fit ​​part 14124 at its end, and the first connector 134 has a second snap-fit ​​part 1341. The second snap-fit ​​part 1341 is snap-fitted to the first snap-fit ​​part 14124 to achieve axial positioning of the roller brush 120.

[0093] In a preferred embodiment of the present invention, each of the first snap-fit ​​portions 14124 is located on the same circumference to form a slot (not shown in the figure), and the second snap-fit ​​portion 1341 is arranged in the slot to snap-fit ​​with the first snap-fit ​​portion 14124.

[0094] The second latching part 1341 is hemispherical, so that the second latching part 1341 can be embedded in the slot to achieve a latching connection with the first latching part 14124.

[0095] Understandably, a limiting structure is formed between the first latching part 14124 and the second latching part 1341. The cooperation between the first latching part 14124 and the second latching part 1341 is used to limit and fix the first connecting member 134 and the second connecting member 141 relative to each other, thereby limiting and fixing the roller brush 120 and the drive assembly 130 to install the roller brush 120 on the floor brush body 110. At the same time, when the roller driver 131 drives the roller brush 120 to roll, the cooperation between the first latching part 14124 and the second latching part 1341 prevents the roller brush 120 from disengaging towards its second end, thereby improving the stability of the roller brush 120 and ultimately improving the cleaning efficiency of the roller brush 120.

[0096] It should be noted that the connection between the first connector 134 and the second connector 141 is not limited to the connection between the second latching part 1341 and the first latching part 14124. Other common detachable mechanical structures, such as magnets, screws, or chemical agents such as adhesives, can also achieve the connection between the first connector 134 and the second connector 141 and can also achieve the axial limitation of the roller brush 120. Therefore, these can also be regarded as specific embodiments of this solution.

[0097] Furthermore, the fixing part 1411 is fixedly connected to the roller brush 120, and at least two driving parts 1342 are arranged in the circumferential area of ​​the second buckle part 1341. Each driving part 1342 is arranged in a corresponding fixing groove 14122. Specifically, the driving part 1342 is a protruding structure.

[0098] Under the action of the rolling driver 131, the roller brush 120 is driven to rotate through the cooperation of the driving part 1342 and the fixing groove 14122.

[0099] It is understood that a snap-fit ​​structure is formed between the drive unit 1342 and the fixing groove 14122. When the rolling driver 131 drives the first connecting member 134 to rotate, the second connecting member 141 is driven to rotate through the cooperation between the drive unit 1342 and the fixing groove 14122, which in turn drives the roller brush 120 to rotate, so as to control the roller brush 120 to perform cleaning work.

[0100] In this invention, the rolling driver 131 drives the roller brush 120 to rotate through the cooperation between the driving part 1342 and the fixing groove 14122. The structure is simple, easy to process and assemble, which greatly improves the assembly efficiency of the overall mechanism and enhances the stability of the overall mechanism.

[0101] In one embodiment of the present invention, the power output end of the rolling drive 131 is directly connected to the first connector 134; or the power output end of the rolling drive 131 is connected to the first connector 134 through the third connector.

[0102] The specific selection of the connection method between the power output end of the rolling drive 131 and the first connector 134 can be determined by the staff according to the actual situation.

[0103] In a preferred embodiment of the present invention, the power output end of the rolling drive 131 is connected to the first connector 134 via the third connector.

[0104] Specifically, in combination Figure 10 and Figure 11 The power output end of the rolling drive 131 is connected to the third connector 135. The third connector 135 is provided with a second fixing part 1351, and the first connector 134 is also provided with a first fixing part 1343. The first fixing part 1343 is sleeved on the outer periphery of the second fixing part 1351 to realize the connection between the first connector 134 and the third connector 135.

[0105] Furthermore, at least one limiting groove 1344 is provided on the inner wall of the first fixing part 1343, and at least one limiting protrusion 1352 is provided on the second fixing part 1351. The limiting protrusion 1352 is adapted to the limiting groove 1344, and the limiting protrusion 1352 is embedded in the limiting groove 1344.

[0106] Furthermore, the drive assembly 130 also includes a fixing member 136, which is sleeved on the outer periphery of the first fixing part 1343 and is fixedly connected to the third connecting member 135 to limit and fix the first connecting member 134 and prevent the first connecting member 134 from separating from the third connecting member 135.

[0107] The rolling driver 131 drives the third connector 135 to rotate, which in turn drives the first connector 134 to rotate. Then, through the cooperation between the driving part 1342 and the fixing groove 14122, it drives the second connector 141 to rotate, and finally drives the roller brush 120 to rotate, so as to control the roller brush 120 to perform cleaning work.

[0108] Furthermore, combined with Figure 2 and Figure 3The drive assembly 130 further includes: a fixed housing 132, which is hollow inside to form a receiving cavity 1321, the rolling drive 131 is installed in the receiving cavity 1321, and the fixed housing 132 is installed in the drive cavity 121.

[0109] Understandably, the roller brush 120 is in a humid environment during operation, and the roller driver 131 needs to be waterproof to ensure its normal use. The present invention arranges the roller driver 131 in a sealed environment by installing the roller driver 131 in the receiving cavity 1321 of the fixed housing 132, thereby ensuring the normal use of the roller driver 131 and extending its service life.

[0110] Furthermore, combined again Figure 3 A limiting member 133 is arranged on the outer periphery of the fixed housing 132, and a limiting part 124 is arranged on the inner wall of the roller brush 120. The maximum outer diameter of the limiting member 133 is greater than the inner diameter of the limiting part 124, and the limiting member 133 abuts against the limiting part 124.

[0111] In a preferred embodiment of the present invention, a first rotating contact surface (not shown in the figure) is provided on the outer periphery of the limiting member 133, and a second rotating contact surface (not shown in the figure) is provided on the inner side of the limiting part 124. The first rotating contact surface and the second rotating contact surface are adapted to each other, and the first rotating contact surface and the second rotating contact surface are in contact and connected.

[0112] Both the first and second rotary bonding surfaces have arc-shaped cross-sections.

[0113] When the rolling driver 131 drives the roller brush 120 to rotate, the first rotating contact surface and the second rotating contact surface cooperate to make the limiting member 133 act like a bearing, so that the roller brush 120 can rotate relative to the fixed housing 132.

[0114] Understandably, a limiting structure is formed between the limiting member 133 and the limiting part 124. In this invention, the cooperation between the limiting member 133 and the limiting part 124 limits the roller brush, preventing the roller brush 120 from moving towards its first end 122, thereby improving the stability of the roller brush 120. At the same time, when the rolling driver 131 drives the roller brush 120 to rotate, the cooperation between the limiting member 133 and the limiting part 124 supports the driving assembly 130, thereby preventing the roller brush 120 from moving up and down in the vertical direction, further improving the stability of the roller brush 120, and ultimately improving the cleaning effect of the roller brush 120.

[0115] Furthermore, the roller brush 120 includes a first end 122 and a second end 123 opposite to each other. One end of the fixed housing 132 is installed from the first end 122 of the roller brush 120 into the drive cavity 121, and the other end of the fixed housing 132 is rotatably connected to the floor brush body 110 through the adapter 150, so as to further realize the complete edge contact of the second end 123 of the roller brush 120 and improve the cleaning effect of the roller brush 120.

[0116] On the other hand, the present invention also relates to a cleaning device, including: a floor brush mechanism as described above.

[0117] It should be understood that the above embodiments are merely illustrative examples of this application and are not intended to limit the scope of this application.

[0118] The various embodiments in this specification are described in a progressive manner. Similar or identical parts between embodiments can be referred to interchangeably. Each embodiment focuses on describing the differences from other embodiments. In particular, the system embodiments are basically similar to the method embodiments, so the description is relatively simple; relevant parts can be referred to the descriptions in the method embodiments.
