The release operating member 141 acts on the first driving wheel 1427 and controls the rotation thereof.

In one embodiment, as shown in fig. 7, the release operation member 141 is slidably disposed on the handle bar 12, and the release operation member 141 and the first driving wheel 1427 are connected by a driving cord 1411.

In a preferred embodiment, the drive line 1411 is a steel wire rope.

During operation, the releasing operation element 141 is pulled along the axial direction of the handle 12, so that the first driving wheel 1427 can be directly driven to rotate through the driving wire 1411, and the stripping claw assembly 142 is driven to clamp the mop protruding out of the edge of the chassis through power transmission; when the mop needs to be released, the releasing operation member 141 is released, the tension spring 1426 is used as a power source, power is transmitted to the first gear 1425, the second transmission wheel 1423, the belt 1424, the first transmission wheel 1427, the transmission cord 1411 and the releasing operation member 141 in sequence, and then the resetting of the releasing operation member 141 is realized.

As shown in fig. 6, the overall operation process of this embodiment includes:

process for stripping cleaning cloth

(1) Pulling the release operation member 141 in the extending direction of the handle bar 12 (see fig. 5 before pulling);

(2) the release operation member 141 drives the first driving wheel 1427 to rotate through the driving wire 1411;

(3) the first driving wheel 1427 drives the second driving wheel 1423 and the second gear to rotate through the belt 1424;

(4) the second driving wheel 1423 drives the first clamping claw 1421 to swing, so that the first contact surface of the first clamping claw is close to the bottom surface of the cleaning cloth 15; meanwhile, the second gear drives the first gear 1425 to rotate, the first gear 1425 drives the second clamping claw 1422 to move downwards, and the first contact surface of the second clamping claw is close to the top surface of the mop cloth 15, and the first contact surface and the second contact surface move oppositely and clamp and fix the mop cloth 15, as shown in fig. 6 (a);

(5) after the position sensor or the pressure sensor senses that the mop is clamped, a signal is transmitted to the controller in the box body, the controller controls the motor and drives the chassis 132 to rotate, for example, the mop rotates for 5 seconds or drives the chassis 132 to rotate for a circle, and one end of the mop is clamped and fixed, so that the mop 15 can be stripped from the lower surface of the chassis when the chassis rotates, and at the moment, the edge of the mop 15 is still clamped by the stripping claw assembly 142, which is shown in fig. 6 (b).

Reset procedure

(1) Releasing the release operation member 141 on the handle bar 12;

(2) the tension spring 1426 pulls the second gripper 1422 to move upward;

(3) the second jaw 1422 transmits power to the first gear 1425, the second gear, and the first jaw 1421 in sequence, the first jaw 1421 swings and returns to the inside of the case, and the mop 15 is released and falls off from below the base plate 132, see fig. 6 (c);

meanwhile, when the second gear rotates, the second transmission wheel 1423 is driven to rotate, so that the power is transmitted to the belt 1424, the first transmission wheel 1427, the transmission cord 1411 and the release operation element 141, thereby resetting the release operation element 141.

In the second embodiment of the present application, compared to the above embodiments, the power source of the first driving wheel 1427 is different, in this embodiment, the first driving wheel 1427 is directly driven by a small motor (not shown) installed in the box, and during the sliding process of the release operating element 141, the release operating element triggers a signal and transmits the signal to the controller in the box, and the controller controls the start of the small motor.

In the third embodiment of the present application, the transmission cord 1411 may also directly act on the second transmission wheel 1423 to directly drive the rotation of the second transmission wheel 1423, in which case the arrangement of the first transmission wheel 1427 and the belt 1424 may be eliminated, if the space layout in the cabinet allows this.

However, it should be noted that, since the sliding distance of the release operating member 141 is not too long, a certain transmission ratio can be controlled by providing two transmission wheels, for example, the diameter of the first transmission wheel 1427 is larger than that of the second transmission wheel 1423, so that the release operating member 141 can realize a large angular deflection of the first clamping jaw 1421 by moving a small distance.

In the fourth embodiment of the present application, the power source of the second driving wheel 1423 is different from that of the third embodiment, in this embodiment, the second driving wheel 1423 is directly driven by a small motor (not shown) installed in the housing, and during the sliding process of the release operating member 141, the release operating member triggers a signal and transmits the signal to a controller in the housing, and the controller controls the small motor to start.

In a fifth embodiment of the application, the second holding jaw 1422 may be a member fixed relative to the housing, and has a second contact surface at its bottom end, which is located above the mop 15 and maintains a relatively fixed gap with the upper surface of the mop, and the second contact surface cannot be lower than the lower surface of the chassis, which would otherwise cause friction with the floor during operation, and too far away from the upper surface of the mop 15, which would otherwise be difficult to hold with the first holding jaw 1421.

In this embodiment, in operation, the first jaw 1421 swings so that its first contact surface approaches the lower surface of the mop 15, and when in contact with the first mop 15, moves further and holds the mop against the second contact surface of the second jaw 1422, the second jaw 1422 remaining relatively stationary with respect to the housing throughout the swinging movement of the first jaw 1421.

In an embodiment of the present application, the release operation member 141 may be disposed on the handle bar 12, or may be disposed on the box, and in the case of the second embodiment and the fourth embodiment, since the communication between the release operation member 141 and the small motor may be in a wireless manner, the release operation member 141 may also be disposed on the negative pressure host 11, and in addition, the release operation member may also be in a button, a toggle switch, a touch screen control manner, or the like.

In an embodiment of the present application, first gripper 1421 may also be moved in two axes, for example, first gripper 1421 is moved downwards to make the first contact surface under mop 15, then moved horizontally in the direction approaching the bottom plate, and then moved further upwards, so as to support the bottom surface of mop 15.

In an embodiment of the present application, the first gripper 1421 and the second gripper 1422 may adopt different power sources, that is, may be controlled independently, for example, the first gripper 1421 may be pulled by a steel wire rope, and the second gripper 1422 may be driven by a small motor.

It will be evident to those skilled in the art that the utility model is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the utility model being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
