When the connection point of the brush set and the control disc is just parallel to the brush set telescopic opening corresponding to the brush set, the length of the brush set exposed out of the brush set telescopic opening reaches the longest, and in this state, the brush set enters a contracted state no matter the control disc controls the brush set to rotate clockwise or the control disc controls the brush set to rotate anticlockwise.

Specifically, when the telescopic sweeping component controls the brush to shrink, the upper sawtooth structure is controlled to descend to the top end of the telescopic opening of the brush, and meanwhile, the lower sawtooth structure is controlled to ascend to the bottom end of the telescopic opening of the brush, so that the upper sawtooth structure is combined with the lower sawtooth structure, and the effect of removing the hair attached and wound on the brush when the brush shrinks is achieved. Conversely, when the telescopic sweeping component controls the brush to stretch, the upper sawtooth structure is controlled to rise, and meanwhile the lower sawtooth structure is controlled to descend, so that the upper sawtooth structure and the lower sawtooth structure do not influence the brush to stretch in the telescopic opening of the brush, and the brush is prevented from being messy or forked due to the influence of the liftable sawtooth structure when the brush stretches. According to the embodiment, the liftable saw tooth structure is designed into the liftable structure, and the targeted lifting adjustment is carried out according to the fact that the brush is in the contracted state or the extended state, so that the brush is cleaned of attached or wound hair, and the brush is prevented from being forked due to the influence of the saw tooth structure, and the brush is cleaned.

It should be noted that the preset length is used for limiting the length of the brush exposed to the telescopic sweeping component through the telescopic opening of the brush, and the specific length of the preset length is set according to actual requirements in actual design production. According to the telescopic sweeping component, the preset length is limited, so that when the brush is controlled to shrink, at least the brush with the length larger than or equal to the preset length is always exposed out of the telescopic sweeping component, the brush can smoothly stretch, the situation that the rotary telescopic controller completely shrinks the brush inside the rotary chassis to cause that the rotary telescopic controller controls the brush to be split when the brush stretches, and the brush cannot be completely and smoothly exposed out of the telescopic component through the brush stretching opening is avoided.
Based on the above embodiments, as a preferred embodiment of the present invention, the rotary telescopic controller in the tenth embodiment of the present invention realizes control of the plurality of groups of brushes in an extended state or a contracted state by adjusting a rotation direction thereof; the rotary telescopic controller realizes the control of the elongation or contraction of the plurality of groups of brushes by adjusting the rotation angle of the rotary telescopic controller.
Specifically, the rotary telescopic controller drives the control disc to rotate through the rotation of the second central rotating shaft, and the control disc controls the extension or contraction of a plurality of groups of brushes connected with the control disc through rotation. As shown in fig. 2, the plurality of groups of brushes are in a normal extension state, and it is to be noted that, in the normal extension state, the length of the brush exposed to the telescopic sweeping component reaches the longest, that is, when the connection point of the brush and the control disc is aligned in parallel with the center of the telescopic opening of the corresponding brush, the length of the brush exposed to the telescopic sweeping component reaches the longest. It should be noted that, the shrinkage or elongation of the plurality of groups of brushes is determined according to the length of the plurality of groups of brushes exposed to the telescopic sweeping component, when the length of the plurality of groups of brushes exposed to the telescopic sweeping component is shortened, the plurality of groups of brushes are shrunk, otherwise, when the length of the plurality of groups of brushes exposed to the telescopic sweeping component is lengthened, the plurality of groups of brushes are elongated. As shown in fig. 3, when the control disc is controlled to contract by rotating counterclockwise, the lengths of the brush sets exposed out of the telescopic sweeping component are shortened, and conversely, the control disc is controlled to change from contract to stretch by rotating clockwise, and the lengths of the brush sets exposed out of the telescopic sweeping component are lengthened. It should be noted that, although the number of brush sets shown in fig. 2 and 3 is 4, in practical design application of the retractable sweeping assembly of the present invention, the number of brush sets may be, but is not limited to, 2 sets, 3 sets, 4 sets or more than 4 sets, by adjusting the number of brush sets, the cleaning density and the cleaning frequency of the retractable sweeping assembly are adjusted, when the number of brush sets is greater, the rotating chassis only needs to rotate by a smaller angle to realize controlling the retractable sweeping assembly to clean for one week, for example, when the number of brush sets is configured to be 4 sets, the rotating chassis only needs to rotate by 90 degrees to realize the effect of cleaning for four sets of brushes for one week, and conversely, when the number of brush sets is less, the rotating chassis only needs to rotate by a larger amount to realize controlling the effect of cleaning for one week of the retractable sweeping assembly, for example: the number of the brush sets is configured to be 2, and the rotating chassis needs to rotate 180 degrees to realize the effect of cleaning two groups of brushes together for one circle.
Specifically, the rotary telescopic controller drives the control disc to rotate through the rotation of the second central rotating shaft, and the rotary telescopic controller 2 controls the elongation or contraction of a plurality of groups of brushes connected with the rotary telescopic controller through controlling the rotation angle of the control disc. The rotation angle of the control disc has a positive correlation with the elongation or contraction amount of the brush 3, and when the rotation angle of the control disc increases, the elongation or contraction amount of the brush also increases. It should be noted that, the rotation angle of control disc is by the rotation angle control of second center pivot, and this embodiment is through control the rotation angle of second center pivot realizes to the brush utensil expose in the length of scalable subassembly of sweeping the floor is controlled, simultaneously, through control the rotation direction of second center pivot realizes to the flexible state of brush utensil is switched, flexible control brush utensil stretches out and draws back, improves the flexible flexibility ratio of subassembly of sweeping the floor. Specifically, when there is a difference in rotational angular velocity between the rotating chassis 1 and the rotating telescopic controller 2, the telescopic state of the plurality of groups of brushes 3 is changed; according to the embodiment, the rotary chassis 1 and the rotary telescopic controller 2 are arranged in the rotary telescopic sweeping component, so that the telescopic state of the brush 3 is determined according to the rotation angular velocity of the rotary chassis 1 and the rotary telescopic controller 2, and the telescopic state of the brush 3 is realized by controlling the rotation angular velocity of the rotary chassis 1 and the rotation telescopic controller 2, so that the purpose that the rotary telescopic sweeping component can flexibly stretch is achieved.
