DETAILED DESCRIPTION

[0049] The technical solutions of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments. It should be noted that the embodiments of the present invention and the features therein may be combined with each other unless there is a conflict.

[0050] It should be noted that the terms "first", "second", etc. in the description and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0051] In the present invention, unless otherwise specified, the directional words used, such as "up, down, top, bottom", usually refer to the directions shown in the drawings, or to the components themselves in the vertical, perpendicular or gravity direction; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above directional words are not used to limit the present invention.

[0052] Example 1

[0053] This embodiment provides a floor brush mechanism 100, see Figure 1 、 Figure 2 and Figure 5 The floor brush mechanism 100 includes a shell 1, a cleaning component 2 and a transmission component 3, wherein the cleaning component 2 and the transmission component 3 are both arranged in the shell 1, and the cleaning component 2 and the transmission component 3 are both wrapped by the shell 1, so that part of the cleaning component 2 can be exposed for cleaning, and the structure is more compact. The transmission component 3 is used to connect with a cutting tool or other components to drive the cutting tool or other components to move.

[0054] Among them, Figure 2 and Figure 3 As shown, the cleaning assembly 2 includes a cleaning member 21 and a cover 22. The cover 22 is detachably arranged on the shell 1. The cleaning member 21 is rotatably arranged on the cover 22. The cleaning member 21 rotates to perform cleaning work. For example, the cleaning member 21 can be set as a cleaning roller brush or a cleaning brush cylinder, etc. One end of the cleaning member 21 can be rotatably installed on the shell 1 through the cover 22. Moreover, when the cover 22 rotates in a first direction relative to the shell 1, the cover 22 can be detached from the shell 1 to be removed from the shell 1.

[0055] When the transmission assembly 3 is connected to the cutting tool, the cutting tool is driven to move by the rotation of the cleaning member 21 to cut the hair and other filaments wrapped around the cleaning member 21, so that the floor brush mechanism 100 can achieve self-cleaning. Figure 4 and Figure 5 As shown, the transmission assembly 3 includes a first transmission member 31 and a second transmission member 32. The first transmission member 31 is connected to the cleaning member 21. When the cleaning member 21 rotates, it can drive the first transmission member 31 to rotate together. One end of the second transmission member 32 is fixed on the cover body 22, and the first transmission member 31 and the second transmission member 32 have a resistance portion. The resistance portion is suitable for acting on the second transmission member 32 when the first transmission member 31 rotates with the cleaning member 21, so as to drive the second transmission member 32 to have a tendency to rotate along the second direction, and the above-mentioned first direction and second direction are opposite, that is, if the first direction is counterclockwise, the second direction is clockwise; if the first direction is clockwise, the second direction is counterclockwise. Set the first direction and the second direction oppositely (such as Figure 3 The second transmission member 32 is shown as the dotted line with the arrow in the middle), thereby preventing the second transmission member 32 from driving the cover body 22 to rotate along the first direction when it has a rotation tendency along the first direction, so that the cleaning member 21 is at risk of the cover body 22 falling off during the rotation. Moreover, if the rotation direction of the second transmission member 32 is consistent with the disassembly direction of the cover body 22, when the cover body 22 is disassembled, the second transmission member 32 will abut against the first transmission member 31, causing wear between the first transmission member 31 and the second transmission member 32. After long-term use, the installation accuracy of the transmission assembly 3 cannot be guaranteed, and the service life of the floor brush mechanism 100 is affected.

[0056] It should be noted that, the forward direction of the floor brush mechanism 100 when working normally is set as the front direction of the floor brush mechanism 100, and the following descriptions on the orientation can all be referred to this.

[0057] A receiving space is formed on the shell 1, and a take-out opening 11 communicating with the receiving space is formed on one side of the shell 1. The cover 22 is detachably arranged at the take-out opening 11, and the cleaning member 21 is located in the receiving space. When the cleaning member 21 is arranged in an elongated strip shape, the shell 1 is arranged in a corresponding shape, having a long side and a short side. The long side of the shell 1 extends along the axial direction of the cleaning member 21, and the short side of the shell 1 is used to connect to the two ends of the cleaning member 21 along its axial direction to enclose the cleaning member 21 therein. The take-out opening 11 is located on the short side of the shell 1. Preferably, the take-out opening 11 can be set on the right side of the shell 1 for easy user operation. Moreover, at least a portion of the bottom of the receiving space is open, so that the cleaning member 21 can be exposed from the open position, which is convenient for cleaning the surface to be cleaned.

[0058] There are many ways to connect the cover 22 to the housing 1. To facilitate the disassembly and assembly of the cover 22, preferably, Figure 9 As shown in , a snap-fitting recess 12 is provided on the inner side wall of the access opening 11, and a snap-fitting portion 23 is provided on the cover 22, which snaps into engagement with the snap-fitting recess 12. The snap-fitting portion 23 snaps into engagement with the snap-fitting recess 12, thereby securing the cover 22 to the access opening 11. When the cover 22 rotates relative to the housing 1 in a first direction, the snap-fitting portion 23 can be released from the snap-fitting recess 12, thereby allowing the cover 22 to be removed from the housing 1. To facilitate rotation of the cover 22, a grip portion can be provided on the end surface of the cover 22. The grip portion can be configured as a handle or a groove, allowing the user to conveniently remove the cover 22 from the housing 1 by holding the handle or inserting a tool into the groove.

[0059] In one embodiment, combined with Figure 13 and Figure 14 As shown, the engaging recess 12 can be set as a engaging hole 121, and the engaging portion 23 is set as a engaging protrusion 231 engaged with the engaging hole 121. A guide portion 113 is provided on one of the access port 11 and the cover body 22, and the other is provided with a guide groove 232 guided and matched with the guide portion 113. The guide portion 113 slides along the guide groove 232 so that the engaging protrusion 231 can be engaged in the engaging hole 121. When the cover body 22 is installed at the access port 11, under the cooperation of the guide portion 113 and the guide groove 232, the cover body 22 is rotated in the second direction, so that the engaging protrusion 231 can be smoothly engaged in the engaging hole 121, thereby fixing the cover body 22 on the shell 1, and the installation is more convenient.

[0060] Furthermore, the guide portion 113 includes a snap-fitting rib 1131 protruding from the inner side wall of the access opening 11, the snap-fitting rib 1131 extending along the circumference of the access opening 11, the snap-fitting hole 121 being concavely provided on the snap-fitting rib 1131, and along the first direction, the snap-fitting rib 1131 having a guide section located in front of the snap-fitting hole 121, the guide section being inclined along the circumference of the access opening 11; the guide groove 232 being provided on the side surface of the cover body 22, the snap-fitting rib 1131 being provided on the guide groove 232, and the snap-fitting rib 1131 being provided on the guide groove 232. The guide groove 232 extends along the circumference of the cover body and has a notch facing the second direction. When the cover body 22 is inserted into the access opening and rotated in the second direction, the guide section of the clamping rib 1131 can extend from the notch into the guide groove 232. When the guide section of the clamping rib 1131 abuts the bottom of the guide groove 232, the clamping protrusion 231 is engaged with the clamping hole 121, so that the cover body 22 cannot continue to rotate in the second direction, that is, it is properly installed. The clamping hole 121 has a rounded corner on at least the rear side along the first direction. When the cover body 22 is disassembled, it is easier for the clamping protrusion 231 on the cover body 22 to fall out of the clamping hole 121.

[0061] The arrangement of the clamping recess 12 and the clamping portion 23 is not limited to the above-mentioned one. In another embodiment, see Figure 9 and Figure 10 The locking recess 12 is set as a locking hole 121', and a guide portion 111 and a limiting portion 112 are formed on the taking and placing port 11. In the first direction, the guide portion 111 is formed on the rear side of the locking hole 121', and the limiting portion 112 is formed on the front side of the locking hole 121'. The guide portion 111 cooperates with the locking portion 23 so that when the cover body 22 rotates along the first direction, the locking portion 23 can be easily disengaged from the locking hole 121', making it easy to disassemble the cover body 22; the limiting portion 112 cooperates with the locking portion 23 so that the locking portion 23 of the cover body 22 can be easily loosened after being locked in the locking hole 121, so that the cover body 22 can be fixed on the shell 1.

[0062] Preferably, if Figure 10As shown in the figure, the clamping hole 121' is concavely arranged on the inner side wall of the access port, and the clamping hole 121' has a first hole wall 1111 and a second hole wall 1121 arranged along the circumference of the access port 11. Along the first direction, the first hole wall 1111 is located at the rear side of the second hole wall 1121. The first hole wall 1111 is inclined along the circumference of the access port 11 and forms a smooth transition with the inner side wall of the access port 11 to form a guide portion 111. The clamping portion 23 is arranged along the first direction. When moving in one direction, the cover body 22 is disengaged from the clamping hole 121' along the inclined first hole wall 1111; the second hole wall 1121 is extended along the radial direction of the access opening 11, and forms a stop fit with the clamping portion 23 along the circumference of the access opening 11 in the second direction to form a limiting portion 112, thereby preventing the cover body 22 from rotating relative to the access opening 11 of the shell 1, fixing the cover body 22 at the access opening 11, and making it easier to install and remove the cover body 22.

[0063] Moreover, the clamping portion 23 can be configured as a telescopic clamping portion. To facilitate the installation of the clamping portion 23, as shown in FIG. Figure 4 As shown in , the cover body 22 includes a first cover plate 221 and a second cover plate 222 connected to each other, a sandwich is formed between the first cover plate 221 and the second cover plate 222, one side of the sandwich is provided with an opening, the clamping portion 23 is provided in the sandwich, and a small portion can extend out of the sandwich from the opening to be clamped in the clamping hole 121; specifically, the clamping portion 23 includes a clamping protrusion 231' and an elastic member, and the two ends of the elastic member along the expansion and contraction direction are respectively connected to the clamping protrusion 231' and the first cover plate 221 or the second cover plate 222, The latching protrusion 231' can extend from the opening to the outside of the interlayer and retract into the interlayer; when the cover 22 is installed, the latching protrusion 231' on the cover 22 retracts into the interlayer under the contact of the inner side wall of the access opening 11. At this time, the elastic member is in a retracted state. When the cover 22 is rotated so that the latching protrusion 231' is opposite to the engaging hole 121', the latching protrusion 231' extends under the elastic restoring force of the elastic member, and is engaged in the engaging hole 121', thereby fixing the cover 22 to the access opening 11 of the housing 1. The elastic member can be configured as a telescopic spring or an elastic rubber member.

[0064] Furthermore, there can be multiple snap-fitting recesses 12, and the multiple snap-fitting recesses 12 are arranged along the circumference of the take-in and put-out port 11; correspondingly, there can be multiple snap-fitting portions 23, and the multiple snap-fitting portions 23 are arranged in one-to-one correspondence with the multiple snap-fitting recesses 12, and multiple snap-fittings make the connection more reliable.

[0065] The cover 22 is detachably mounted on the housing 1 , and the cover 22 is connected to the second transmission member 32 , thereby making the installation and removal of the second transmission member 32 more convenient.

[0066] Specifically, for the transmission component 3, if Figure 4As shown, the transmission assembly 3 is arranged in the cleaning member 21, and the cleaning member 21 is roughly hollow cylindrical. A mounting cavity connected to the cover body 22 is formed in the cleaning member 21. The cover body 22 is arranged to cover one end of the cleaning member 21. In addition, a fixing rod 4 is arranged in the mounting cavity. One end of the fixing rod 4 is fixedly connected to the cover body 22, and the other end of the fixing rod 4 is connected to the second transmission member 32, thereby fixing the second transmission member 32 to the cover body 22. When the cover body 22 rotates in the first direction, the fixing rod 4 and the second transmission member 32 can be driven to rotate in the first direction at the same time. However, when the cleaning member 21 is working normally, the cleaning member 21 rotates in the second direction. At this time, the cover body 22 is fixed relative to the housing 1. Therefore, when the cleaning member 21 rotates, the second transmission member 32 is in a fixed state and does not rotate, so that the cover body 22, the fixing member and the second transmission member 32 do not rotate relative to each other, and the connection is more reliable and more stable.

[0067] The cover 22 is set on the right side of the cleaning member 21. In order to facilitate the installation of the transmission assembly 3, the right end of the fixing rod 4 can be fixed to the cover 22 first, such as by screws or buckles. Figure 8 As shown in , a first plug-in portion 41 is provided at one end of the fixing rod 4 away from the cover body 22 (i.e., the left end of the fixing rod 4), and a second plug-in portion 322 is provided on the second transmission member 32. The first plug-in portion 41 and the second plug-in portion 322 are plugged into each other, and then the second transmission member 32 is plugged into the other end of the fixing rod 4, thereby connecting the fixing rod 4 and the second transmission member 32. The first plug-in portion 41 and the second plug-in portion 322 can limit the relative rotation of the fixing rod 4 and the second transmission member 32. When assembling the floor brush structure, the fixing rod 4 can be first fixed to the cover body 22, and then the second transmission member 32 can be plugged into the left end of the fixing rod 4 to form a whole. Then, this whole is extended from the right end of the cleaning member 21 into the installation cavity of the cleaning member 21, which is more convenient to install.

[0068] Preferably, if Figure 8 As shown in , one of the first plug-in portion 41 and the second plug-in portion 322 is configured as a plug-in protrusion 3221, and the other is configured as a plug-in groove 411 that is plugged into and matched with the plug-in protrusion 3221, and the plug-in direction of the plug-in protrusion 3221 and the plug-in groove 411 is arranged along the axial direction of the cleaning member 21, so that the second transmission member 32 will not rotate relative to the cover body 22. Moreover, during assembly, the second transmission member 32 can be first fixed in the cleaning member 21, and then the fixing rod 4 and the cover body 22 can be extended into the cleaning member 21 from the end of the cleaning member 21, so that the first plug-in portion 41 and the second plug-in portion 322 are plugged into and installed in place, which can improve the matching accuracy of the first transmission member 31 and the second transmission member 32, and make it more convenient to disassemble the cover body 22.

[0069] like Figure 8As shown, the fixing rod 4 is arranged in a hollow rod shape, the plug-in groove 411 is arranged on the side wall of the fixing rod 4, and has an opening arranged in the axial direction. The end of the second transmission member 32 is inserted into the fixing rod 4, and the plug-in protrusion 3221 includes a protrusion protruding from the circumference of the second transmission member 32. When the end of the second transmission member 32 is inserted into the fixing rod 4, the plug-in protrusion 3221 can be inserted into the plug-in groove 411 to form a rotation-proof fit, and a stop portion is formed at the plug-in end of the plug-in protrusion 3221. After the plug-in protrusion 3221 is plugged into the plug-in groove 411, the end of the fixing rod 4 abuts against the stop portion, thereby limiting the plug-in depth of the second transmission member 32 to ensure installation accuracy.

[0070] Furthermore, one end of the second transmission member 32 is connected to the fixing rod 4. To make the installation of the second transmission member 32 more stable, the other end of the second transmission member 32 can be fixed in the cleaning member 21. Specifically, Figure 5 and Figure 7 As shown, a mounting hole 211 is provided in the cleaning member 21, and a mounting seat is protruded on the inner side wall of the mounting cavity of the cleaning member 21. The mounting hole 211 is formed on the mounting seat. The mounting hole 211 passes through the mounting seat along the axial direction of the cleaning member 21, and the other end of the second transmission member 32 is passed through the mounting hole 211, thereby supporting the other end of the second transmission member 32, and the second transmission member 32 is in contact with the mounting hole 211, forming a stop fit along the axial direction of the cleaning member 21, thereby limiting the second transmission member 32 along the axial direction of the cleaning member 21 to prevent the second transmission member 32 from moving.

[0071] Preferably, at least two mounting holes 211 are provided, and the above-mentioned interference portion is formed between at least two adjacent mounting holes 211, so that the first transmission member 31 and the second transmission member 32 are more stable when they abut against each other, thereby preventing the second transmission member 32 from moving. In order to avoid wear between the second transmission member 32 and the cleaning member 21, the floor brush mechanism 100 also includes a third sleeve and a fourth sleeve. The third sleeve and the fourth sleeve are respectively fixedly mounted on the inner sides of the two mounting holes 211, and the second transmission member 32 is rotatably mounted on the inner sides of the third sleeve and the fourth sleeve. The third sleeve and the fourth sleeve can both be metal parts. The third sleeve and the fourth sleeve can effectively protect the cleaning member 21 from wear. When the third sleeve and the fourth sleeve are worn, it is more convenient than replacing the cleaning member 21 and it also saves maintenance costs.

[0072] Moreover, when the transmission assembly 3 is used to connect with the cutting tool, the transmission assembly 3 can convert the rotation of the cleaning member 21 into the movement of the cutting tool, so that the self-cleaning of the floor brush mechanism 100 can be achieved through the cutting tool. Specifically, a matching portion 3111 is formed on the first transmission member 31, and a guiding portion 3211 is formed on the second transmission member 32. When the first transmission member 31 rotates along the second direction with the rotation of the cleaning member 21, the matching portion 3111 is engaged with the guiding portion 3211, and the first transmission member 31 rotates with the second transmission member 32 as the rotation center axis to convert it into the self-rotation of the first transmission member 31. When the cutting tool is connected to the first transmission member 31, the cutting tool can be driven to rotate, thereby performing cutting.

[0073] Preferably, if Figure 11 As shown, the first transmission member 31 includes a worm wheel 311, and the second transmission member 32 includes a worm 321 meshed with the worm wheel 311, and the worm 321 is extended along the axial direction of the cleaning member 21, one end of the worm 321 is plugged into the fixing rod 4, and the other end of the worm 321 is passed through and fixed in the above-mentioned mounting hole 21, so that the worm 321 forms the rotation center axis of the cleaning member 21. When the cleaning member 21 rotates along the rotation center axis and in the second direction, it drives the first transmission member 31 to rotate around the second transmission member 32 in the second direction. Since the worm 321 is meshed with the worm wheel 311, during the rotation of the first transmission member 31, the worm 321 causes the worm wheel 311 to rotate, thereby driving the cutting tool to rotate. Moreover, the rotation direction of the worm 321 teeth of the worm 321 is consistent with the second direction, and the worm 321 is also subjected to the force of the worm wheel 311, so that the worm 321 tends to rotate along the second direction. Since the worm 321 cannot rotate under the action of the cover body 22, the cover body 22 tends to rotate in the locking direction relative to the shell 1 under the action of the worm 321. Therefore, the cover body 22 is more tightly connected to the shell 1, which can make the floor brush mechanism 100 work more reliably.

[0074] Similarly, in order to prevent the first transmission member 31 from being damaged by friction with the cleaning member 21 during rotation, the cleaning assembly 2 also includes a connecting assembly 5, which includes a connecting rod 51 and a first sleeve and a second sleeve. The first sleeve and the second sleeve are fixed to the cleaning member 21, and the connecting rod 51 can rotate relative to the first sleeve and the second sleeve. The first transmission member 31 is sleeved on the connecting rod 51 and is tightly matched with the connecting rod 51. The rotation of the first transmission member 31 can drive the connecting rod 51 to rotate, and the cutting tool can be fixed on the connecting rod 51, thereby driving the cutting tool to rotate to achieve cutting.

[0075] Furthermore, in order to ensure the smooth rotation of the cleaning member 21, the cleaning assembly 2 also includes a bearing 24, and the two ends of the bearing 24 along its axial direction are respectively in contact with the cleaning member 21 and the cover body 22 to limit the bearing 24 in the axial direction to prevent the bearing 24 from moving axially. The fixing rod 4 is sleeved on the inner side of the inner ring of the bearing 24, and the cleaning member 21 is sleeved on the outer side of the outer ring of the bearing 24. The fixing rod 4 is fixed to the cover body 22, so that the cleaning member 21 can rotate relative to the cover body 22.

[0076] Moreover, for the housing 1, in order to better achieve water and electricity separation, as Figure 12 As shown in the figure, the housing 1 includes an upper cover 13, a lower cover 14, and an end cover 15 provided on one side. The upper cover 13 is provided on the upper side of the lower cover 14 and forms an installation space. The installation space can be used for installing a driving motor for driving the cleaning member 21 to rotate. The above-mentioned receiving space is formed on the lower cover 14, and the lower cover 14 is completely covered on the peripheral side of the cleaning member 21, completely isolating the installation space from the receiving space to prevent water stains or dirt formed during the cleaning process of the cleaning member 21 from entering the installation space; the end cover 15 is set on the right side, and the receiving space is open on the right side. The cleaning component 2 is open and can be extended into the receiving space from the opening on the right side when being installed. The left end of the cleaning member 21 is first installed on the shell 1. The above-mentioned access opening 11 is formed on the end cover 15. The end cover 15 is connected with the upper cover 13 and the lower cover 14 through a hook structure. After the cleaning member 21 is installed on the lower cover 14, the end cover 15 is covered on the opening on the right side to fix the cleaning member 21. Then, the overall self-access opening 11 formed by the cover body 22, the fixing rod 4 and the second transmission member 32 is extended into the cleaning member 21, which is easy to install.
