The invention provides a cleaning structure 100, wherein the cleaning structure 100 can be a dust collector, a floor washing machine or an automatic mop machine and is used for cleaning a surface to be cleaned.

The first position is farther from the proximal end of the body than the second position.

As shown in fig. 1, 16 and 17, the connecting piece 42 slides reciprocally relative to the mounting body 41, so that the floor brush mechanism 3 is driven to move reciprocally relative to the main body 1, so that when the distal end of the connecting piece 42 and the distal end of the connector 2 are both accommodated in the mounting body 41, the connecting piece 41 cannot rotate relative to the connector 2, as shown in fig. 16, so that the floor brush mechanism 3 is locked on the main body 1, so that the floor brush mechanism 3 cannot shake relative to the main body 1 in the non-working state, and is more stable; when the floor brush mechanism 3 is to perform cleaning work, in the first position, the connecting member 42 and the mounting body 41 are unlocked first, the connecting member 42 slides from the first position to the second position, and moves to the position shown in fig. 1, the distal end of the connecting member 42 and the distal end of the connecting head 2 extend out of the mounting body 41, in the second position, the connecting member 42 is switched from the unlocked state to the locked state again, and the connecting member 42 is locked on the mounting body 41, correspondingly, at this time, the connecting head 2 can rotate relative to the connecting member 42, that is, the machine brush mechanism 3 rotates relative to the main body 1, as shown in fig. 17, so as to realize the working state of the floor brush mechanism 3.

When the cleaning structure 100 is set to be placed horizontally as shown in fig. 1, the longitudinal direction of the main body 1 is set in the left-right direction, and the floor brush mechanism 3, the connecting mechanism 4 and the main body 1 are sequentially disposed in the left-right direction, the proximal end of the floor brush mechanism 3 and the proximal end of the connecting mechanism 4 are both near one end of the main body 1, the distal end of the floor brush mechanism 3 and the distal end of the connecting mechanism 4 are both far from one end of the main body 1, that is, the proximal end of the floor brush mechanism 3 is the right end of the floor brush mechanism 3, the distal end of the floor brush mechanism 3 is the left end of the floor brush mechanism 3, the proximal end of the connecting mechanism 4 is the right end of the connecting mechanism 4, and the distal end of the connecting mechanism 4 is the left end of the connecting mechanism 4. Namely, one end of the main body far away from the connecting mechanism is provided for manual operation, correspondingly, one end close to the manual operation is a near end, and one end far away from the manual operation is a far end.

When the floor brush mechanism 3 is connected with the main body 1 through the connector 2 and the mounting body 41, in order to keep the dust collection of the cleaning structure 100 smooth, corresponding dust collection channels are also arranged in the connector 2 and the mounting body 41, specifically, the main body 1 comprises a housing 11 of the main body, and the housing 11 of the main body can be internally provided with dust collection drivers, controllers, dust collection boxes and other components, and the dust collection drivers can provide dust collection power for the floor brush mechanism 3 and control the floor brush mechanism 3 to perform cleaning work through the controllers; as shown in fig. 13 and 14, a first channel 423 is provided in the connecting member 42, the distal end of the first channel 423 is communicated with the dirt sucking channel 321 on the floor brush mechanism 3, the proximal end of the first channel 423 is communicated with the air duct of the dust sucking driver, and the dust sucking driver forms a suction air flow to enable dirt outside the cleaning structure 100 to enter the cleaning structure 100 from the dirt sucking channel 321 of the floor brush mechanism 3 and flow into the first channel 423, and is introduced into the dust collecting box in the main body 1 along with the air duct of the dust sucking driver for temporary storage.

For the connector 2, the proximal end of the connector 2 is rotationally connected with the connecting piece 42, specifically, referring to fig. 4, 12 and 13, a rotating cavity 23 is provided at the proximal end of the connector 2, a first opening 231 is provided at the proximal end surface of the rotating cavity 23, and a avoiding notch 211 is provided on the peripheral sidewall of the first opening 231, the avoiding notch 211 is recessed from the proximal end toward the distal end at the first opening 231, the distal end of the connecting piece 42 is rotatably provided in the rotating cavity 23, and the proximal end of the connecting piece 42 extends out of the first opening 231 and is slidably connected with the mounting body 41; when the connecting piece 42 rotates relative to the connector 2, the part of the connecting piece 42 extending out of the first opening 231 can be abutted against the avoidance notch 211 and the peripheral side wall of the first opening 231, and the upper position and the lower position of the rotation of the connecting piece 42 are limited by the avoidance notch 211 and the peripheral side wall of the first opening 231, so that the relative rotation angle of the connecting piece 42 and the connector 2 can be prevented from being too large, and the cleaning structure 100 is easy to operate. Preferably, in the working state, the length direction of the connecting piece 42 intersects with the length direction of the connecting head 2, and the intersecting angle is an obtuse angle, so that the floor brush mechanism 3 is more convenient to clean. Of course, the cleaning structure can be at right angles or acute angles, so that the cleaning structure can be moved in the opposite direction, such as backward.

For example, in the first position, the floor brush mechanism 3 and the main body 1 extend in the left-right direction, and when the floor brush mechanism 3 moves to the second position, the user can manually rotate the floor brush mechanism 3 or the main body 1 to rotate upwards or downwards, so that the connecting piece 42 rotates at a certain angle relative to the connecting head 2, and thus the floor brush mechanism 3 and the main body 1 are arranged at a certain angle, so that the floor brush mechanism 3 can be more attached to the surface to be cleaned, and the main body 1 is more convenient for a user to hold.
