[0042] Lifting and rotating mop assembly:

[0043] The lifting and rotating mop assembly in the embodiment of the present application is as follows: Figure 1 , 2 As shown, it includes a rotating shaft member 1, a connecting lifting member 2, a mopping member 3 and a driving device 4 for driving the rotating shaft member 1 to rotate;

[0044] The driving device 4 is connected to the rotating shaft 1, and the rotating shaft 1 is provided with a positioning column 01 for connecting the connecting lifting component 2. The connecting lifting component 2 is provided with an inclined groove 02 inclined along the circumferential direction, and the positioning column 01 is inserted into the inclined groove 02;

[0045] The connecting lifting member 2 is fixedly connected to the mop member 3. When the driving device 4 drives the rotating shaft member 1 to rotate, the positioning column 01 is driven to move in the inclined groove 02 to push the mop member 3 to rise and fall.

[0046] Specifically, the driving device 4 adopts a rotary motor, which can be controlled to rotate forward or reverse. The rotating shaft 1 is installed on the output shaft of the driving device 4, and the driving device 4 drives the output shaft and the rotating shaft 1 to rotate synchronously.

[0047] The connecting lifting member 2 is connected to the lower end of the rotating shaft member 1, and the two are connected through the positioning column 01 and the inclined groove 02. The inclined groove 02 limits the positioning column 01. During the rotation of the rotating shaft member 1, the positioning column 01 is always located in the inclined groove 02, so that the connecting lifting member 2 and the rotating shaft member 1 maintain a connected relationship.

[0048] When the driving device 4 drives the rotating shaft member 1 and the connecting lifting member 2 to move relative to each other, and the positioning column 01 moves in the inclined groove 02, since the height of the positioning column 01 in the rotating shaft member 1 remains unchanged, the connecting lifting member 2 is driven to move up and down along the axial direction of the rotating shaft member 1. Specifically, when the positioning column 01 moves from the lower end of the inclined groove 02 to the upper end of the inclined groove 02, the connecting lifting member 2 drives the mop member 3 to descend; when the positioning column 01 moves from the upper end of the inclined groove 02 to the lower end of the inclined groove 02, the connecting lifting member 2 drives the mop member 3 to rise.

[0049] In the embodiment of the present application, an inclined groove 02 is provided on the connecting lifting member 2 connected to the mop member 3, and a positioning column 01 cooperating with the inclined groove 02 is provided on the rotating shaft member 1. When the driving device 4 drives the rotating shaft member 1 to rotate, the positioning column 01 is driven to move in the inclined groove 02, thereby pushing the mop member 3 to rise and fall, so that the mop member 3 is set as a movable structure, and the mop member 3 can be raised in a position where it is inconvenient to scrub, such as on a carpet.

[0050] In one embodiment, if Figure 3 As shown, the inclined slot 02 includes a first end 21 and a second end 22, and the first end 21 is higher than the second end 22;

[0051] When the rotating shaft 1 rotates forward, the positioning column 01 is driven to rotate from the second end 22 to the first end 21, driving the mop member 3 to descend to the lowest point and then rotate forward;

[0052] When the rotating shaft 1 is reversed, the positioning column 01 is driven to rotate from the first end 21 to the second end 22, driving the mop member 3 to rise to the highest point.

[0053] In the present application, when the positioning column 01 is located at the higher first end 21, the mop member 3 is located at the lowest point, at which time the mop member 3 can fit the ground for scrubbing, and when the positioning column 01 is located at the lower second end 22, the mop member 3 is located at the highest point, at which time the mop member 3 is in an ascending and retracting state. The driving device 4 controls the ascending and descending of the mop member 3 by adjusting the rotation direction of the rotating shaft member 1.

[0054] The lifting process of the mop member 3 is described below:

[0055] Taking the positioning post 01 at the first end 21 of the inclined slot 02 as the initial state, the mop member 3 is at the lowest point.

[0056] At this time, the driving device 4 drives the rotating shaft 1 to rotate forwardly, and the positioning column 01 is limited by the inclined groove 02, and the rotating shaft 1 drives the mop part 3 to rotate forward synchronously, so that the mop part 3 keeps rotating when scrubbing the floor to improve the cleaning effect.

[0057] When the carpet needs to be folded up, the driving device 4 drives the rotating shaft 1 to reverse. At this time, the mop part 3 still rotates forward under the action of inertia, and the positioning column 01 can move from the first end 21 to the second end 22 at a faster speed, driving the mop part 3 to rise to the highest point in the process.

[0058] Afterwards, the driving device 4 can stop rotating, and the connecting lifting member 2 or the mopping member 3 can be restricted at the highest point by setting a positioning structure such as a magnet; the driving device 4 can also continue to reverse, driving the mopping member 3 to reverse synchronously, so that the mopping member 3 remains at the highest point.

[0059] When the floor needs to be scrubbed after passing the carpet area, the drive device 4 controls the rotating shaft 1 to rotate forward, and the positioning column 01 moves to the first end 21 again, driving the mop member 3 to drop to the lowest point, and then the drive device 4 continues to rotate forward to scrub the floor.

[0060] Among them, after the mop member 3 rises to the highest point, if the driving device 4 stops rotating, the mop member 3 is kept at the highest point by setting a positioning structure, which can effectively reduce energy consumption; if the driving device 4 continues to rotate in the opposite direction to keep the mop member 3 at the highest point, when the mop member 3 is subsequently lowered, due to the inertia of the mop member 3 itself, the mop member 3 can be lowered at a faster speed, thereby improving the response speed. The above two methods can be selected and used according to needs in actual applications.

[0061] In the lifting and rotating mop assembly of this embodiment, the driving device 4 can control the lifting and lowering of the mop member 3, and can also control the rotation of the mop member 3 when scrubbing the floor, and at the same time improves the lifting speed of the mop member 3, achieving multiple technical effects through a simple structure.

[0062] In one embodiment, two positioning posts 01 protruding in the radial direction of the rotating shaft 1 are arranged on the outer circumferential surface of the rotating shaft 1, and the two positioning posts 01 are arranged on the same straight line;

[0063] The connecting lifting member 2 is arranged in a ring shape, and its inner side wall is provided with two inclined grooves 02 , the rotating shaft member 1 is partially inserted into the connecting lifting member 2 , and the two positioning columns 01 are respectively inserted into the two inclined grooves 02 .

[0064] Specifically, the rotating shaft 1 is cylindrical, and its lower end portion is inserted into the connecting lifting member 2. Two protruding positioning columns 01 are provided on the outer circumference of the rotating shaft 1, and the positioning columns 01 are inserted into the inclined grooves 02 on the inner side wall of the connecting lifting member 2. The two inclined grooves 02 are symmetrically arranged with the axis of the connecting lifting member 2 as the symmetry axis.

[0065] In this embodiment, two positioning posts 01 are provided to improve the connection stability between the rotating shaft member 1 and the connecting lifting member 2 .

[0066] Optionally, the number of positioning posts 01 and inclined grooves 02 can also be set to three or more, and the positioning posts 01 are evenly arranged on the outer circumferential surface of the rotating shaft 1, and all positioning posts 01 are in the same plane. The inclined grooves 02 are evenly arranged on the inner wall of the connecting lifting member 2 along the circumference of the connecting lifting member 2, and the inclination angles and lengths of all inclined grooves 02 are the same, and a positioning post 01 is inserted into each inclined groove 02. It should be noted that in order to reduce the sliding resistance of the positioning post 01 in the inclined groove 02, the inclination angle of the inclined groove 02 from the first end 21 to the second end 22 cannot be too large, so it is better to set the number of inclined grooves 02 and positioning posts 01 to two or three.

[0067] Furthermore, if Figure 3 , 4 As shown, the connecting lifting member 2 includes a first member 03 and a second member 04, and the first member 03 is installed in the second member 04;

[0068] The first piece 03 is provided with an arc-shaped protrusion 31, and the arc-shaped protrusion 31 is arranged along the circumference of the first piece 03;

[0069] The inner side wall of the second piece 04 is provided with an arc-shaped receiving groove 41 , into which the arc-shaped protrusion 31 is inserted, and an inclined groove 02 is formed between the arc-shaped receiving groove 41 and the arc-shaped protrusion 31 .

[0070] Specifically, the arc-shaped protrusion 31 protrudes upward on the first piece 03, and the upper end surface of the arc-shaped protrusion 31 is arc-shaped, and its arc shape is set according to the groove shape of the inclined groove 02; the second piece 04 is installed above the first piece 03, and the lower end of the inner wall of the second piece 04 is provided with an arc-shaped receiving groove 41, and the arc shape of the upper edge of the arc-shaped receiving groove 41 is also set according to the groove shape of the inclined groove 02. When the arc-shaped protrusion 31 is inserted into the arc-shaped receiving groove 41, the inclined groove 02 is formed between the arc-shaped receiving groove 41 and the arc-shaped protrusion 31.

[0071] The first piece 03 and the second piece 04 are fastened and connected by a first bolt.

[0072] During installation, after the rotating shaft 1 passes through the second piece 04 from bottom to top, the positioning column 01 is abutted against the upper edge of the arc-shaped receiving groove 41, and then the first piece 03 is inserted into the second piece 04 from bottom to top, and then the first piece 03 and the second piece 04 are fixed by the first bolt. The assembly process is convenient and the positioning column 01 can be stably inserted.

[0073] In one embodiment, if Figure 4 As shown, at least one limiting protrusion 32 is provided on the first piece 03 , and at least one limiting groove 42 is correspondingly provided on the second piece 04 , and each limiting protrusion 32 is embedded in a limiting groove 42 .

[0074] Specifically, the limiting protrusion 32 is arranged on the outer side surface of the arc-shaped protrusion 31, and the limiting groove 42 is arranged at the lower end of the second piece 04. The limiting protrusion 32 and the limiting groove 42 are used to position the first piece 03 and the second piece 04 during installation to facilitate the screwing in of the first bolt.

[0075] In one embodiment, if Figure 3 , 4 As shown, the connecting lifting member 2 also includes an annular fixing member 05;

[0076] A positioning flange 33 is provided at the lower end of the first piece 03. After the annular fixing piece 05 is covered onto the positioning flange 33, the annular fixing piece 05 and the mop piece 3 are fastened together by a second bolt.

[0077] After the rotating shaft member 1, the first member 03 and the second member 04 are installed as a whole, the annular fixing member 05 is covered from top to bottom above the positioning flange 33, and then the second bolt is screwed in to connect the annular fixing member 05 and the mop member 3. The annular fixing member 05 simultaneously fixes the rotating shaft member 1, the first member 03 and the second member 04 on the mop member 3.

[0078] Specifically, if Figure 4 As shown, at least two notches 34 are provided on the positioning flange 33, and the notches 34 separate the positioning flange 33 into at least two flange units;
