Embodiment 4

As shown in FIG. 6 to FIG. 8, in this embodiment, a floor mopping machine comprises a shell 100, and a wiping object 102 is movably disposed below the shell 100 and is mounted on a wiping plate. The wiping object 102 is arranged movably with respect to the shell 100, that is, the wiping object 102 is able to rotate circumferentially, roll or reciprocate horizontally. Generally, the wiping plate is driven by a motor to drive the wiping object 102 to move, or the wiping plate is manually driven to drive the wiping object 102 to move. In this embodiment, the floor mopping machine further comprises a roller 3 in contact with the wiping object 102. When the floor mopping machine is used for cleaning, the roller 2 is separated from the wiping object 102. During cleaning, the roller 2 contacts with water and then rolls to carry water to the wiping object 102. During water removal, the roller 3 stops rolling, the wiping object 102 rubs against the roller 3, so that water on the wiping object 102 is removed. So, users need to control the water level properly to ensure that the roller 3 is neither completely immersed in water nor separated from water. If the roller 3 does not contact with water, water will not be supplied for cleaning. If the roller 3 is immersed in water, water on the wiping object 102 will not be removed later. After the water level is properly controlled, the wiping object 102 is placed above the roller 3, and then the roller 3 rotates to supply water to clean the wiping object 102. After the wiping object 102 is cleaned with water, the roller 3 is kept static, and the wiping object 102 rubs against the roller 3 to remove water. In this embodiment, the roller 3 may be locked with a pin to be kept static, or is prevented from rolling by a barrier, or is locked through a brake structure, and other common techniques in the prior art may also be adopted to keep the roller 3 static. In this embodiment, the roller supplies water to clean the wiping object in a rotating state, and rubs against the wiping object to remove water on the wiping object in a static state, and the position of the roller does not need to be changed when used for cleaning and water removal, so that operation is easy.

Preferably, the roller 3 is able to roll unidirectionally, that is, the roller 3 can roll clockwise or anticlockwise, and cannot roll reversely. When water is supplied to clean the wiping object 102, the wiping object 102 moves forward to drive the roller 3 to roll, so that water is supplied to the wiping object 102; and during water removal, the wiping object 102 moves reversely, the roller 3 cannot roll reversely and is kept static, and at this moment, the wiping object 102 rubs against the roller 2, so that water on the wiping object 102 is removed. In this embodiment, a ratchet mechanism may be used to realize unidirectional rolling of the roller 3, and the ratchet mechanism in the prior art is a unidirectional intermittent movement mechanism formed by a ratchet wheel and a pawl. In this embodiment, a ratchet wheel is disposed on the roller 3, a pawl is rotatably connected to a bucket body, and when the pawl abuts against the ratchet wheel, the roller 3 starts to roll unidirectionally. In this embodiment, the roller rolls unidirectionally, and is driven to roll when the wiping plate moves, so when the wiping object is cleaned, users can supply water to clean the wiping object or remove water on the wiping object merely by controlling the movement of the wiping plate, and cleaning and water removal may be synchronized accurately.

Preferably, the floor mopping machine further comprises a bucket body, and the roller 3 is disposed in the bucket body and is able to roll in the bucket body. The bucket body is used to contain water, and the roller 3 may be moved together with the bucket body, so that transfer is easy.

In this embodiment, the bucket body 1 is provided with a first detection element 4, the floor mopping machine is provided with a second detection element C5, and the first detection element C4 interacts with the second detection element C5 to generate instructions. The floor mopping machine may be placed in the bucket body 1 in two different directions. Because the floor mopping machine may be placed in the bucket body 1 in two different directions, two different instructions may be generated by the interaction of the first detection element C4 and the second detection element C5.

In this embodiment, a single chip microcomputer is disposed in the floor mopping machine. The single chip microcomputer determines the position of the floor mopping machine according to an instruction received, and takes, after analyzing the instruction received, corresponding control, such as triggering an alarm to remind an operator to make a correction; or, the single chip microcomputer selects a corresponding control mode according to an input instruction. Specifically:

In this embodiment, when the floor mopping machine is placed in the bucket body 1 in an incorrect direction, the first detection element C4 and the second detection element C5 interact to give a warning. The operator corrects the direction in which the floor mopping machine is placed in the bucket body 1 according to the warning, to ensure that the wiping object 102 of the floor mopping machine is cleaned with water first and then water on the wiping object 102 is removed.

In this embodiment, the floor mopping machine selects a control mode suitable for cleaning the wiping object 102 according to two different instructions. One control mode is that the wiping object 102 moves forward first and then moves reversely, and the other control mode is that the wiping object 102 moves reversely first and then moves forward. The wiping object 102 should be cleaned with water before water removal, and the roller 3 rolls unidirectionally, so the wiping object 102 should move first in a direction allowing the roller 3 to roll and then move reversely to make the roller 3 static, so as to meet the requirement for cleaning before water removal. In this embodiment, the wiping object can be cleaned with water before water removal no matter in which direction the floor mopping machine is placed in the bucket body by an operator, and no correction needs to be made by the operator.

In this embodiment, two different instructions may be generated according to different directions in which the floor mopping machine is placed in the bucket body. Specifically, when the floor mopping machine is placed in the bucket body, the first detection element C4 and the second detection element C5 interact to generate a first instruction which corresponds to the control mode that the wiping object moves forward first and then moves reversely, or a second instruction which corresponds to the control mode that the wiping object moves reversely first and then moves forward. In this way, the floor mopping machine does not need to be reversed manually, operation is easy, an error is avoided, and the wiping object may be cleaned strictly according to the cleaning requirement.

In this embodiment, the first detection element C4 and the second detection element C5 may be common technical means in the prior art, or be specifically implemented as follows:

In this embodiment, the first detection element C4 is a permanent magnet, and the second detection element C5 is a Hall switch or a reed switch; or, the position of the first detection element C4 and the position of the second detection element C5 are exchanged. The permanent magnet is able to trigger the Hall switch or the reed switch, the distance and direction between the permanent magnet and the Hall switch or the reed switch vary according to different positions of the floor mopping machine in the bucket body, different instructions will be generated by the interaction of the permanent magnet and the Hall switch or the reed switch, and the single chip microcomputer in the floor mopping machine determines the position of the floor mopping machine in the bucket body according to an instruction received.

As another preferred implementation, in this embodiment, the first detection element C4 and the second detection element C5 are both permanent magnets. The distance and direction between the two permanent magnets vary according to different positions of the floor mopping machine in the bucket body, and different instructions will be generated by the interaction of the two permanent magnets.

As another preferred implementation, the first detection element C4 is a microswitch, and the second detection element C5 is a trigger for triggering the microswitch. According to different positions of the floor mopping machine in the bucket body, the trigger triggers the microswitch or does not trigger the microswitch, so two instructions are generated.

As another preferred implementation, the first detection elements C4 and the second detection element C5 are a cavity and a protrusion 41 to be inserted into the cavity respectively. Preferably, the cavity is formed in the floor mopping machine, and the protrusion 41 is disposed on the bucket body. According to different positions of the floor mopping machine in the bucket body, the protrusion 41 is inserted into the cavity or is not inserted into the cavity and jacks the floor mopping machine. When the protrusion 41 is inserted into the cavity, the floor mopping machine can be placed in the bucket body smoothly. When the cavity mismatches the protrusion 41, the floor mopping machine cannot be placed in the bucket body smoothly due to the interference of the protrusion 41. So, two instructions are generated. The operator obtains the positional information of the floor mopping machine according to the two instructions.
