Referring to fig. 9 and 10, the present application provides a dual drum cleaner mop for being mounted on a base 200 of a floor cleaner, the dual drum cleaner mop including two single drum cleaner mops 100, the two single drum cleaner mops 100 being rotatably mounted on opposite sides of the base 200, and the driving part being capable of driving the single drum cleaner mops 100 to rotate and lift relative to the floor.

In this embodiment, the single drum cleaner mop head 100 is the single drum cleaner mop head 100 shown in fig. 1. With reference to the principle of the single-drum cleaner mop 100, it can be seen that when the dual-drum cleaner mop is moved forward or backward by an external force, the two bearing rollers 2004, the cleaning rollers 20, the two bearing rollers 21 and the driving wheels 22 of each single-drum cleaner mop 100, which are disposed in the two mounting grooves 2003, are all located on the same plane, that is, the two single-drum cleaner mops 100 are all in contact with the ground, the driver 30 does not operate to save energy, and the lifting frame 210 does not move relative to the base 200 of the ground cleaner. When the two cleaning rollers 20 rotate, the friction force between the cleaning rollers 20 and the ground is equal, and the mop head of the double-roller cleaner keeps static or moves linearly at a constant speed under the action of a balance force according to Newton's first law. In order to break the balance, the forward and backward movement of the base 200 of the floor cleaner is controlled by means of the forward and backward rotation of the driving wheel 22, so that the two single drum cleaner heads 100 on both sides of the base 200 are moved by the rotary joint 16, and at this time, the moving direction of the two single drum cleaner heads 100 is the same as that of the floor cleaner base 200.

In other embodiments, the powered wheels are universal wheels, and the cleaning roller 20 drives the universal wheels to move the base 200 of the floor cleaner. Specifically, the universal wheels do not provide driving force, and only the cleaning driving members inside the two cleaning rollers 20 provide power for the movement of the single-roller floor cleaner mop heads 100 installed on the two opposite sides of the base, so as to drive the universal wheels 22 to realize the movement of the base 200 of the floor cleaner, thereby ensuring the consistency of the overall movement of the double-roller floor cleaner mop heads when the single-roller floor cleaner mop heads 100 on the two sides are installed on the base 200.

When the double-roller cleaner mop rotates, the two drivers 30 along the diagonal direction of the base 200 drive the first sub swing arm 41 arranged on the driver 30 to swing, the first sub swing arm 41 pushes the second sub swing arm 42 to drive the bearing roller 21 to move outwards relative to the second accommodating groove 14, and the other bearing roller 21 arranged opposite to the bearing roller 21 moves into the second accommodating groove 14, so as to support the housing 10 to drive one side of the cleaning roller 20 to be lifted relative to the ground, that is, one side of the two cleaning rollers 20 along the diagonal direction of the base 200 is lifted relative to the ground, and the other side of the two cleaning rollers 20 deepens the interference with the ground. The friction between the other side of the cleaning roller 20 and the deepened ground makes the double-roller ground cleaner obtain the moment of rotation, so that the mop head of the double-roller ground cleaner can rotate. At this time, the mop head of the twin drum cleaner is inclined with respect to the ground, and the rotary joint 16 connected to the mop head of the twin drum cleaner is also moved, so as to push the lifting frame 210 to move in a direction perpendicular to the ground outside the base 200 of the ground cleaner in a direction away from the ground, that is, the lifting frame 210 is lifted up with respect to the base 200 of the ground cleaner, the two mop heads 100 of the single drum cleaner are twisted with respect to the lifting frame 210 and inclined with respect to the ground, and the two bearing rollers 21 and the driving wheels 22 provided on the base 200 of the ground cleaner are still in contact with the ground, thereby ensuring stability when the lifting frame 210 is lifted up and when the mop head of the twin drum cleaner is rotated.

The present application further provides a floor cleaner comprising a wand detachably secured to a base 200 of the floor cleaner and a single drum cleaner mop 100 or a dual drum cleaner mop. In this embodiment, one embodiment of the single drum cleaner mop 100 is the single drum cleaner mop 100 shown in fig. 1 described above, and one embodiment of the double drum cleaner mop is the double drum cleaner mop shown in fig. 9 described above.

The application provides a single cylinder cleaner drags head 100 accessible electric power energy supply and absorbs subaerial rubbish and dust, can clear up firmly attached subaerial dust to can realize freely turning, also need not to last the energy supply and maintain the operation in the process of marcing of ground cleaner, the energy consumption is lower.
