The gravity center direction of the balancing piece is located on the center line of the balancing piece, and the posture angle is the angle direction formed by the gravity center direction of the balancing piece and the gravity direction. In addition, the floor brush structure further comprises a controller, wherein the controller is electrically connected with the first driving piece and the attitude sensor and is used for controlling the operation of the first driving piece according to the attitude angle. Obviously, after the attitude sensor acquires the attitude angle, the balance member is connected to the outer drum, so that the angle between the gravity center formed by the outer drum and the balance member and the gravity direction can be determined. And then the operation of the first driving piece is controlled through the controller so as to control the operation piece to rotate, and further the position of the synthetic center of gravity formed by the operation piece, the outer roller and the balance piece is changed, so that the position of the synthetic center of gravity is changed within a preset range.
In the technical scheme, when the posture angle is the first angle, the controller controls the first driving piece to rotate in the first direction; when the attitude angle is a second angle, the controller controls the first driving piece to rotate in a second direction, wherein the first direction is opposite to the second direction, and the center line of the balancing piece corresponding to the first angle and the center line of the balancing piece corresponding to the second angle are respectively positioned on two sides of the gravity center of the outer roller along the extension line of the gravity direction.

In this solution, the runner can rotate around the axis of the outer drum between a first position and a second position. It should be noted here that the first position and the second position are two positions in which the maximum angle can be achieved when the runner rotates around the outer drum. That is, the runnability component can be swung around the axis of the outer drum between a first position and a second position. In addition, the balancing piece is positioned outside the circumferential range formed by the first position and the second position, namely the radius of the swinging of the running piece of the balancing piece is smaller than the radius of the rotation of the balancing piece, and the balancing piece and the running piece do not interfere with each other when moving, so that the balancing piece and the running piece can rotate simultaneously.

Further, the floor brush structure 100 includes an attitude sensor 110, and the attitude sensor 110 can acquire an attitude angle of the center line of the balance piece 104 with respect to the gravity direction. The gravity center direction of the balance piece 104 is on the center line of the balance piece 104, and the posture angle is an angle direction formed by the gravity center direction of the balance piece 104 and the gravity direction. In addition, the floor brush structure 100 further comprises a controller 112, wherein the controller 112 is electrically connected to the first driving member 108 and the attitude sensor 110, and is used for controlling the operation of the first driving member 108 according to the attitude angle. It is apparent that, when the attitude angle is acquired by the attitude sensor 110, since the balance member 104 is connected to the outer drum 102, the angle of the gravity center formed by the outer drum 102 and the balance member 104 with the gravity direction can be determined.

The center line corresponding to the first angle and the center line corresponding to the second angle are respectively located on two sides of the gravity direction, so that the balance piece moves between the first angle and the second angle, in other words, the first angle is the maximum angle which can be reached by the posture angle in one direction, and the second angle is the maximum angle which can be reached by the posture angle in the other direction.
Specifically, setting the first angle and the second angle of the attitude angle is understood to limit the maximum range of the rotation angle of the balance member 104 and the rolling outer cylinder, and ensure that the balance member 104 can swing between the first angle and the second angle. In order to counteract the forward and backward shaking of the center of gravity formed by the swinging of the balance piece 104 and influence the use of the floor brush structure 100, the running piece 106 can be rotated in opposite directions, so that the position of the combined center of gravity of the running piece 106, the balance piece 104 and the outer roller 102 does not swing back and forth too much as possible, and only the periodic center of gravity movement is formed in the vertical direction, so that the periodic pressure on the ground is formed, and the deep cleaning of stubborn dirt is realized.

It is clear that the outer drum 102 is now in a position-locked state and is no longer rotating, and therefore its position of the center of gravity is not changed.
At this time, the controller 112 controls the first driving member 108 to rotate in the third direction, so as to adjust the position of the center of gravity of the moving member 106, and thus the floor brush structure 100 can perform the action of wiping the dirt back and forth.

Still be equipped with operation piece 106 in outer cylinder 102, operation piece 106 can take place the all-phase motion for outer cylinder 102, in addition, the focus of operation piece 106 does not coincide with the focus of outer cylinder 102, therefore, when outer cylinder 102 takes place to rotate, operation piece 106 can be through rotating the circumferential position angle of adjustment self for outer cylinder 102 and balancing member 104, control the whole focus of scrubbing brush structure 100, make the focus of scrubbing brush structure 100 can carry out continuous adjustment according to the function of predetermineeing, and then form constantly changing pressure to ground, make scrubbing brush structure 100 when carrying out the dust absorption cleanness, form the vibration to stubborn dirt, in order to improve cleaning performance.
Generally, the outer drum 102 is a cylinder for directly cleaning the ground in the floor brush structure 100, and the outer wall thereof may be a material for easily adsorbing dirt on the ground, such as fluff or flocked hair. The balance member 104 is provided in the outer drum 102 and connected to the outer drum 102, and the balance member 104 is connected to the outer drum 102 such that the centers of gravity of the balance member and the outer drum 102 do not coincide with each other and form an eccentric structure common to the outer drum 102, and thus the centers of gravity of the balance member and the outer drum 102 are simultaneously changed when the outer drum 102 rotates. Obviously, the change of the center of gravity may be up and down in addition to the front and back change. Also disposed within outer drum 102 is a runnability component 106, the center of gravity of which is not coincident with outer drum 102, and the center of gravity of which may together form a composite center of gravity. When the outer roller rotates, the rotating member 106 can be adjusted to rotate, so that the resultant gravity center formed by the rotating member and the outer roller 102 can be changed according to the cleaning requirement, thereby realizing the cleaning function of the floor brush structure 100. If the formed composite gravity center is changed up and down all the time, the up-and-down vibration is realized, and the heavy cleaning can be carried out on stubborn stains; or the formed composite gravity center is downward and repeatedly changed back and forth, and stubborn stains can be repeatedly cleaned by adding weight.
Further, as shown in fig. 2, a first driving member 108 is disposed on the outer roller 102, and the first driving member 108 is connected to the running member 106 in a transmission manner to drive the running member 106 to move. Generally, the first driving member 108 uses a motor as a driving element to move the operation member 106. It should be noted that the first driving member 108 is disposed on the outer roller 102, and when the outer roller 102 rotates, the first driving member 108 rotates in a same step.
Further, the floor brush structure 100 includes an attitude sensor 110, and the attitude sensor 110 can acquire an attitude angle of the center line of the balance piece 104 with respect to the gravity direction. The gravity center direction of the balance piece 104 is on the center line of the balance piece 104, and the posture angle is an angle direction formed by the gravity center direction of the balance piece 104 and the gravity direction. In addition, the floor brush structure 100 further includes a controller 112, and the controller 112 is electrically connected to the first driving member 108 and the attitude sensor 110, and is used for controlling the operation of the first driving member 108 according to the attitude angle. It is apparent that, when the attitude angle is acquired by the attitude sensor 110, since the balance member 104 is connected to the outer drum 102, the angle of the gravity center formed by the outer drum 102 and the balance member 104 with the gravity direction can be determined. The operation of the first driving member 108 is controlled by the controller 112 to control the rotation of the operation member 106, so as to change the position of the resultant center of gravity formed by the operation member 106, the outer drum 102 and the balance member 104, within a preset range.
Further, when the attitude angle is a first angle, the controller 112 controls the first driving member 108 to rotate in a first direction; when the attitude angle is a second angle, the controller 112 controls the first driving member 108 to rotate in a second direction opposite to the first direction. The first angle is the maximum angle which can be reached by the attitude angle in one direction, and the second angle is the maximum angle which can be reached by the attitude angle in the other direction.
Specifically, setting the first angle and the second angle of the attitude angle is understood to limit the maximum range of the rotation angle of the balance 104 and the rolling outer cylinder, and ensure that the balance 104 can swing between the first angle and the second angle. In order to counteract the forward and backward shaking of the center of gravity formed by the swinging of the balance member 104 and to influence the use of the floor brush structure 100, the operation member 106 can be rotated in the opposite direction, so that the position of the combined center of gravity of the operation member 106, the balance member 104 and the outer roller 102 does not swing back and forth too much as possible, and only the periodic center of gravity movement is formed in the up and down direction, so that the periodic pressure on the floor is formed, and the deep cleaning of stubborn dirt is realized.
Further, the second driving member 114 is electrically connected to the outer roller 102, and the second driving member 114 can drive the outer roller 102 to rotate. It should be noted that the second driving member 114 can drive the outer roller 102 to rotate at a certain speed in a certain direction, and can also drive the outer roller 102 to change the rotating direction during the rotation.
Generally, the center of gravity formed by the outer drum 102 and the balance 104 does not coincide with the axis of the outer drum 102, and therefore, when the outer drum 102 rotates, the center of gravity also rotates around the axis of the outer drum 102. The second driving member 114 controls the outer roller 102 to rotate, so that the floor brush structure 100 can form a pressure varying on the ground while cleaning, thereby cleaning stubborn stains.
Further, the floor brush structure 100 further includes a command receiving device 116 electrically connected to the controller 112, and the controller 112 controls the second driving member 114 to maintain the current posture of the outer roller 102 according to the fixed point cleaning command received by the command receiving device 116. It is clear that the outer drum 102 is now in a position-locked state and is no longer rotating, and therefore its position of the center of gravity is not changed.
At this time, the controller 112 controls the first driving member 108 to rotate in the third direction, so as to adjust the position of the center of gravity of the moving member 106, and thus the floor brush structure 100 can perform the action of wiping the dirt back and forth. Wherein the third direction is a rotational direction of the first driving member 108 relative to the outer roller 102.
Further, the floor brush structure 100 further includes a timer 118, the timer 118 is electrically connected to the controller 112, the rotation time of the operation member 106 can be set by the timer 118, and the controller 112 can control the operation of the first driving member 108 according to the rotation time set by the timer 118. Particularly, when the floor brush structure 100 performs the action of wiping stains before and after a fixed point, the timer can provide preset time, so that a user can automatically complete fixed-point cleaning of stubborn stains on the ground by using the floor brush structure 100, and the floor brush structure is convenient for the user to use.
Further, the runner 106 is rotatable about the axis of the outer drum 102 between a first position and a second position. It should be noted that the first position and the second position are two positions in which the maximum angle can be achieved when the operation member 106 rotates around the outer drum 102. That is, the runnability component 106 can be swung around the axis of the outer drum 102 between a first position and a second position. Furthermore, the balance member 104 is located outside the circumferential range formed by the first position and the second position, i.e., the balance member 104 is located at a radius where the operation member 106 swings smaller than the radius where the balance member 104 rotates, and the two members do not interfere with each other when moving, and thus can rotate at the same time.
Further, the balance member 104 and the operation member 106 are arc-shaped. The axis of the balance member 104 is collinear with the axis of the runnability component 106 and the axis of the outer drum 102. It can be understood that the three are coaxial, so that the arrangement of the moving structure in the outer roller 102 can be simplified, and the interference between the three can be avoided to the maximum extent.
In addition, the center of gravity of the arc-shaped structure is offset from the axis position, so that a centrifugal force can be effectively formed during rotation, and a vibration effect on dirt is generated during cleaning of the floor brush structure 100.
Further, the radial positions of the balance member 104 and the operation member 106 with respect to the axis of the outer drum 102 are different, so that the positions in the radial direction may overlap, enabling the synchronous rotation without interference.
Further, as shown in fig. 3, the floor brush structure 100 further includes a housing 120, and the outer drum 102 is disposed in the housing 120. The housing 120 has a first hole 122 and a second hole 124 at opposite sides thereof, respectively, and the medium can flow into the housing 120 through the first hole 122 and be discharged to the outside through the second hole 124 by the outer drum 102.
Generally, the floor brush structure 100 can be used in a vacuum cleaner, and the outer roller 102 within the floor brush structure 100 can be rotated to perform a sweeping or brushing-like action to clean the floor. In addition, the housing 120 is provided with a first hole 122 and a second hole 124 on both sides, so that negative air pressure can be applied to the floor brush structure 100, and the medium on the floor can be sucked from the first hole 122 and discharged into the second hole 124 for collection.
Because the outer roller 102 can move through the inner structure, the floor brush structure 100 can form variable pressure on the ground, and stubborn stains on the ground can be intensively cleaned.
Further, the number of the outer rollers 102 of the floor brush structure 100 is two, and the outer rollers are disposed at both sides of the first hole 122, and the rotation directions thereof are opposite. When the outer roller 102 rotates, a sweeping or brushing action can be performed on the ground, so that the medium such as dirt, debris, sundries on the ground is carried away from the ground and into the housing 120. It is apparent that when the two outer drums 102 are rotated at the same time, it is easier to bring the media into the inside of the housing 120, and to the second hole 124 and then to be discharged outside, because the rotation directions thereof are opposite. The two outer drums 102 can collect the medium inside the casing 120 more effectively than the structure having only one outer drum 102.
In another specific embodiment, two outer rollers 102 are respectively disposed in the front-back direction of the housing 120, and can drive the medium into the housing 120 during cleaning. Generally, the track of the floor brush structure 100 moves back and forth when the floor brush structure 100 performs cleaning. Therefore, the two outer drums 102 are disposed in tandem, and the media can be effectively prevented from falling down at the time of cleaning.

Further, the vacuum cleaner 200 includes a main body 204 and a handle 206. The main unit 204 is disposed on a link of the dust suction apparatus 200, and is used for controlling operations of various structures in the dust suction apparatus 200. A handle 206 is provided at the other end of the dust extraction link 202 remote from the brush arrangement 100, and a user can use the dust extraction apparatus 200 to clean the floor by holding the handle 206 when in use.
In addition, the dust collection connecting rod 202 includes any one of the floor brush structures 100 in the above embodiments, so that any beneficial effect in any one of the above embodiments is achieved, and details are not repeated herein.

The principle of the center of gravity among the outer roller, the balance half cylinder and the dynamic half cylinder in the floor brush structure is shown in figure 5, wherein m is1To balance the mass of the half cylinder, m2For moving half cylinder masses, mcSynthesizing equivalent mass for two half cylinders, wherein alpha is the included angle between the gravity center of the synthesis cylinder and the reference coordinate system of the gravity center of the balance half cylinder, and beta is the included angle between the gravity center of the motion half cylinder and the reference coordinate system of the gravity center of the balance half cylinder, as shown in the figure m1Has a polar coordinate of (0, r)1),m2Has a polar coordinate of (β, r)2) From the coordinates and masses of the two half cylinders, m can be calculatedcHas polar coordinates of (alpha, r)c) And then the generated exciting force is obtained according to the formula of the exciting force as follows:
F=mcrcw2,
wherein, F is the exciting force, and w is the rotation angular velocity of the motor.
FIG. 5, FIG. 6, FIG. 7 and FIG. 8 show the operation principle of the inner and outer drum coordination control when the outer drum (i.e. the outer drum 102) of the floor brush structure is detected to rotate to the angle θ1And when the angle theta is an included angle between a gravity center reference coordinate system of the balance half cylinder and the vertical direction of the ground, the actuating mechanism controls the moving half cylinder to rotate anticlockwise, and the target is controlled to move to a required angle according to the eccentric moment. When the outer cylinder moves to the angle theta2When the friction force is generated, the exciting force is vertical to the ground, and the generated friction force is maximum. The outer cylinder continues to rotate to the angle theta3And when the system is in a state of being in a neutral state, the actuating mechanism controls the motion half cylinder to rotate clockwise, the balance state is recovered, and the eccentric control of the system is finished. Thereby realizing average maximum pressurization control within one period of the outer cylinder, and controlling the angular amplitude to be theta3-θ1。
In another specific application scenario, when the floor brush structure encounters a stain which needs to be cleaned intensively, the relative position of the outer cylinder and the balance half cylinder is controlled by the dust collector to be locked, the moving half cylinder is controlled by the actuating mechanism to do reciprocating motion, forward acting force as shown in fig. 9, downward acting force as shown in fig. 10 and backward acting force as shown in fig. 11 are respectively realized, and therefore the action of wiping the stain forwards and backwards by the rolling brush is realized. The erased force-time curve can be analyzed into a position control track planning target curve of the motor, so that the structure can realize intelligent force curve control.
In sum, the floor brush structure generates ground cleaning force pressurization through an eccentric structure, so that the cleaning capability of the floor brush in the process of stubborn dirt and stains can be effectively improved, and the dust removal effect of the dust collector is enhanced. In addition, the eccentric structure is controlled through the actuator, so that the timing and positioning eccentric control can be realized, and the problem of insufficient experience of eccentric vibration to a user is effectively solved. The ground brush structure in the embodiment can realize intelligent force curve control through a double-motor synchronous control strategy, and meets more diversified and complicated application scenes.
The ground brush structure in this embodiment can realize the fixed point and to ground pressure boost. The actuator structure automatically controls eccentricity without human intervention. The double motors are synchronously controlled to realize an intelligent torque curve. According to the design, derivative control such as up-and-down vibration beating, backward or forward power assisting and the like is realized.
