Referring to fig. 3, the floor brush part 30 includes a housing 37 and a roll brush (also sometimes referred to as a cleaning brush by those skilled in the art) provided on the housing 37 and driven to rotate at a high speed to mop the floor. In order to secure the mopping efficiency, the number of the roll brushes may be two, respectively, a front roll brush 341 and a rear roll brush 342, and particularly, the roll brushes are designed to be cylindrical. The housing 37 has opposite front and rear portions, the front roll brush 341 being provided at the front portion of the housing 37, and the rear roll brush 342 being provided at the rear portion of the housing 37. The front rolling brush 341 and the rear rolling brush 342 support the floor brush part 30 together, and support the floor brush part 30 on a working surface, which is the supporting surface of the front rolling brush 341 and the rear rolling brush 342, of the floor brush part 30. It will be appreciated that the work surface is generally a level ground. Specifically, the front roll brush 341 and the rear roll brush 342 are arranged side by side, the axes of the front roll brush 341 and the rear roll brush 342 are parallel to each other, and both are at least partially housed in the housing 37, and a space is provided between the front roll brush 341 and the rear roll brush 342 to form an installation space. Referring to fig. 3, the axes of the front and rear roll brushes 341 and 342 are substantially perpendicular to the front-rear direction of the housing 37.

The structure of the double-roll scrubber, the structure of the floor brush part 30 and the functional relationship between the two are generally described above, and the floor brush part 30 and the roll brush detaching structure of the floor brush part 30 will be described in detail below.

Referring to fig. 3, fig. 3 is a schematic structural diagram of a floor brush part 30 including a roller brush dismounting structure. It should be understood that the drawing is merely an example for explaining that the roller brush dismounting structure can be used for the floor brush part including the double roller brushes, and it is not intended that the roller brush dismounting structure can be used only for the floor brush part including the double roller brushes. The roller brush detaching structure will be described below by taking the floor brush part 30 including the double roller brushes as an example.

The floor brush part 30 has a housing 37, and the housing 37 has opposite front and rear portions, and correspondingly front and rear roll brushes 341 and 342 are mounted at the front and rear portions of the housing 37. One side (e.g., the right side, i.e., the side facing the view in fig. 3) of the housing 37 is provided with a roll brush detaching structure at a position corresponding to the front and rear roll brushes 341 and 342, which can facilitate detachment of the front and rear roll brushes 341 and 342 from the housing 37 or relatively facilitate re-attachment of the detached front and rear roll brushes 341 and 342 to the housing 37.

In one implementation scenario, the roller brush dismounting structures are all mounted on the same side of the housing 37, as shown in fig. 3, that is, the roller brush dismounting structure corresponding to the front roller brush 341 is mounted on the right side of the housing 37, and the roller brush dismounting structure corresponding to the rear roller brush 342 is also mounted on the right side of the housing 37. It is to be understood that, since the front and rear roll brushes 341 and 342 are provided with the roll brush detaching structure, for convenience of description, the roll brush detaching structure provided at the front roll brush 341 will be hereinafter referred to as a front roll brush detaching mechanism, and the roll brush detaching structure provided at the rear roll brush 342 will be hereinafter referred to as a rear roll brush detaching mechanism.

In this embodiment, when the front roll brush 341 is detached from the housing 37 by the front roll brush detaching mechanism, the detaching direction thereof is substantially forward; when the rear roller brush 342 is removed from the housing 37 by the rear roller brush removing mechanism, the removal direction is substantially rearward, and the removal directions are opposite to each other.

Accordingly, when the front roller brush 341 has a front roller brush detaching mechanism at its right end, the front roller brush 341 may have a mechanism such as the pivot joint 82 at its left end, and the rear roller brush 342 may be configured similarly. Referring to fig. 6-7, fig. 6 and 7 are schematic structural views of the floor washing machine with the floor brush 30 in a use state and a maintenance state, respectively. When the right ends of the front rolling brush 341 and the rear rolling brush 342 are both provided with the rolling brush detaching structure, the left ends of the front rolling brush 341 and the rear rolling brush 342 are both provided with the swivel joint 82, and the left ends of the front rolling brush 341 and the rear rolling brush 342 are rotatably connected with the inner side of the housing 37 through the respective swivel joints 82.

Further, the rotary joint may specifically include a fixed portion and a rotary shaft portion. One end of the fixing portion is connected to the inner side of the housing 37, and the other end is provided with a rotating shaft through hole. One ends of the front and rear roll brushes 341 and 342 are provided with roll brush through holes corresponding to the rotation shaft through holes. The rotating shaft part sequentially penetrates through the rotating shaft through hole and the rotating shaft through hole, so that one end of the front rolling brush and one end of the rear rolling brush are rotatably connected with the inner side of the shell 37.

In another modified embodiment, the left and right ends of the front and rear roll brushes 341 and 342 may be provided with corresponding roll brush detaching mechanisms, respectively. Thus, the front brush detaching mechanisms are respectively arranged at the left end and the right end of the front brush 341; the left end and the right end of the rear rolling brush 342 are respectively provided with a rear rolling brush dismounting mechanism; the front rolling brush dismounting mechanism and the rear rolling brush dismounting mechanism have the same structure.

In one embodiment, the portion of the roller brush dismounting structure exposed outside the housing 37 has a corresponding thrust piece 72. The pushing member 72 may be a combination body including a button body 721 and a cone 722, wherein the cone 722 is integrally formed inside the button body 721 and extends inward. Through pressing the button body 721, the cone 722 and other mechanisms are driven to be linked, and the corresponding front rolling brush 341 or the corresponding rear rolling brush 342 can be detached from the shell 37, so that the front rolling brush 341 and the rear rolling brush 342 can be integrally detached and installed, and the difficulty in detaching and installing the rolling brushes is simplified.

In the above embodiments, the general function of the roller brush detaching mechanism is described, and the specific structure of the roller brush detaching mechanism will be described in detail below.

Specifically, referring to fig. 4, the roller brush detaching structure in one embodiment of the present invention mainly includes a retainer 71, a pushing member 72, and an elastic member 73, and the retainer 71, the pushing member 72, and the elastic member 73 are usually independent elements. Wherein,

the clamping member 71 comprises a force-bearing end 711, a clamping end 712 and a pivoting part 713 positioned between the force-bearing end 711 and the clamping end 712; a thrust member 72 adapted to the force receiving end 711 of the retainer 71; the elastic member 73 has one end connected to the catching end 712 of the catching member 71 or connected to a portion between the pivoting part 713 and the catching end 712 of the catching member 71.

The catching member 71 is pivotally connected to the sides of the front and rear roll brushes (341, 342) by a pivot portion 713. That is, when the force-bearing end 711 of the retainer 71 is acted upon by a force, the retainer 71 can rotate around the pivot portion 713 as a general center. For example, when the force-bearing end 711 of the retainer 71 is acted on by a clockwise moment, the retainer 71 rotates clockwise around the pivot 713 as a whole. When the catch 71 is rotated as a whole, the catch end 712 thereof can be disengaged from the housing 37.

The force of the force-bearing end 711 of the retainer 71 can be from the pushing member 72, for example, in an implementation scenario, when the pushing member 72 is pressed by a user, at this time, the pushing member 72 is in force-bearing contact with the force-bearing end 711 of the retainer 71, and the user pressing force received by the pushing member 72 (the pressing force is perpendicular to the side of the roller brush) is transferred into a moment that pushes the retainer 71 in a plane parallel to the side of the roller brush, so that the retainer 71 rotates around the pivot 713, and finally the retaining end 712 of the retainer 71 is separated from the housing 37.

Further, the pushing member 72 may include a button body 721 and a tapered body 722. A taper 722 is formed at one side of the button body 721 and extends inward. The force-receiving end 711 of the catch 71 has a ramp portion that mates with the cone 722. When the button body 721 is pressed, the taper 722 is engaged with the slope portion, thereby converting a force applied to the button body 721 into a force pushing the rotation of the catch 71.

In one embodiment, in order to ensure the firmness of the holding member 71 with the housing 37, the holding member 71 may include a first hook 714 and a second hook 715, and the first hook 714 and the second hook 715 are disposed opposite to each other in the vertical direction and have substantially the same structure. The first hook 714 and the second hook 715 each have a force-bearing end 711, a latching end 712, and a pivot portion 713. At this time, the pushing member 72 is fitted to an area portion between the first hook 714 and the second hook 715. Specifically, the pushing member 72 is located between the force-bearing end of the first hook 714 and the force-bearing end of the second hook 715, when the pushing member 72 is pressed, the pushing member 72 can push the first hook 714 and the second hook 715 to rotate simultaneously, and the directions of rotation of the first hook 714 and the second hook 715 are opposite.

In this embodiment, two ends of the elastic member 73 are respectively connected to the first hook 714 and the second hook 715; the elastic member 73 may be, but is not limited to, an elastic member such as a spring. When the pushing member 72 is pressed, the pushing member 72 is in force-bearing contact with the respective force-bearing ends of the first hook 714 and the second hook 715, so as to simultaneously drive the first hook 714 and the second hook 715 to rotate around the respective pivot portion 713.

Normally, the elastic member 73 is in a compressed state, having a compression potential energy, and having a tendency to move towards both ends. That is, when the roll brush is mounted to the housing 37 of the floor brush part 30, the elastic member 73 is compressed, and the compressed elastic member 73 accumulates elastic force to urge the first and second hooks 714 and 715 to be respectively caught to the housing 37.

When the pushing member 72 receives the pressing force of the user, the pushing member 72 contacts the force-bearing ends 711 of the first hook 714 and the second hook 715 respectively, and at this time, the first hook 714 rotates clockwise around its own pivot 713 as a center of circle, and the second hook 715 rotates counterclockwise around its own pivot 713 as a center of circle, so that the holding end of the first hook 714 and the holding end of the second hook 714 compress the elastic member 73 at the same time, and the elastic member 73 overcomes the elastic force of the elastic member 73, so that the first hook 714 and the second hook 715 are separated from the housing.

Generally, when the pushing member 72 has a structure of a button body 721, since the button body 721 is provided to receive the pressing force of the user, the button body 721 needs to be leaked from the side of the housing 37. The housing 37 may be provided with an open groove 81 on a side surface of the housing 37 in order to be structurally adapted to the above-described brush removal structure, so that the brush removal structure is installed in the open groove 81.

In addition, when the retaining member 71 is the first hook 714 and/or the second hook 715, the first hook 714 and/or the second hook 715 have a hook-shaped end, which is the retaining end 712 playing a retaining function, and correspondingly, in order to adapt to the shape of the hook-shaped end, the bottom of the open slot 81 is provided with a slot 82, and the slot 82 is used for accommodating the hook-shaped end, as shown in fig. 5.

When a user cleans the roll brush, the roll brush (front roll brush, rear roll brush) needs to be disassembled. When the rolling brush is detached, a user only needs to press the button body 721 on the side cover of the floor brush part 30, at this time, the one end of the rolling brush is released from the constraint, the rolling brush after the constraint is released can be dragged along the opening direction of the open slot under the dragging of the user, the other end of the rolling brush can rotate along the rotation center position shown by the rotation joint 82, so that the end of the rolling brush provided with the button body 721 is exposed, at this time, the front rolling brush 341 or the rear rolling brush 342 is in a maintenance state (shown in fig. 7), and the user can pull out the rolling brush outwards to clean and maintain. If the use state of the floor brush part 30 needs to be recovered after the cleaning of the roller brush is completed, the roller brush is pushed in, the roller brush rotates towards the floor brush part body by taking the rotary joint 82 as a rotation center, so that the installation of the roller brush is completed, and at this time, the use state of the floor brush part 30 is recovered (namely, as shown in fig. 6).

The direction of disassembly and assembly of the drum brush may be a vertical direction or an obliquely upward direction, in addition to a horizontal direction, corresponding to the maintenance state and the use state of the drum brush, which may be selectively set according to the specific structure of the scrubber, and will not be described in detail herein.

The above are only a few specific embodiments of the present invention, and any other modifications based on the concept of the present invention are considered to be within the scope of the present invention.
