A first rotating member 211 and a second rotating member 212 which are arranged back and forth in the first direction in the rotating assembly 21, and a connecting assembly 214 which connects the first rotating member 211 and the second rotating member 212. The connecting assembly 214 includes a first connecting member 215 and a second connecting member 216, wherein the first connecting member 215 is mechanically connected to the first rotating member 211, and the second connecting member 216 is mechanically connected to the second rotating member 212. It is to be understood that in the present application, the mechanical connection may be a fixed connection or a rotational connection.

Specifically, a first combining portion 2151 is disposed at an end of the first connecting member 215 close to the second connecting member 216, a second combining portion 2161 is disposed at an end of the second connecting member 216 close to the first connecting member 215, and the first combining portion 2151 and the second combining portion 2161 are slidably sleeved and connected. The arrangement is such that the first connecting element 215 and the second connecting element 216 can be telescopically connected, and the first rotating element 211 and the second rotating element 212 can be moved closer to or away from each other by the elastic restoring element 217. Alternatively, the first combining part 2151 is the first positioning groove 213, the second combining part 2161 is the second positioning groove 213, and the height of the second positioning groove 213 in the third direction is greater than that of the second positioning groove 213, so that when the first connecting member 215 and the second connecting member 216 approach each other, the first positioning groove 213 protrudes into the second positioning groove 213 to achieve the sliding laminated connection of the first combining part 2151 and the second combining part 2161.

A first fastener 2152 is disposed on one side of the first connecting member 215 facing the second connecting member 216, and a second fastener 2162 corresponding to the first fastener 2152 is disposed on one side of the second connecting member 216 facing the first connecting member 215. The first latch 2152 passes over the second latch 2162 and is connected to the second latch 2162 from the direction close to the second rotating element 212. When the rotating assembly 21 is in the expanded state, the first locking member 2152 is locked to the second locking member 2162, and when the rotating assembly 21 is in the retracted state, the first locking member 2152 and the second locking member 2162 are away from each other along the first direction. At this time, the first latch 2152 moves toward the second rotator 212, and the second latch 2162 moves toward the first rotator 211.

Optionally, a first elastic restoring member 2171 is further disposed between the first connecting member 215 and the second connecting member 216, and when the first latch member 2152 is latched with the second latch member 2162, the first elastic restoring member 2171 is in a first compressed state with no or small pressure. When the first latch 2152 and the second latch 2162 are away from each other along the first direction, the first elastic restoring member 2171 is changed from the first compression state to the second compression state under a larger pressure. At this time, the first elastic restoring member 2171 generates a large restoring force so that the first and second connection members 215 and 216 have a tendency to be distant from each other.

The first connecting member 215/the second connecting member 216 is provided with a resetting component 218, the resetting component 218 is provided with a third latch 2181, one of the first connecting member 215 and the second connecting member 216, which is not provided with the resetting component 218, is provided with a fourth latch 2163, when the rotating component 21 is in the unfolding state, the third latch 2181 and the fourth latch 2163 are away from each other along a second direction perpendicular to the first direction, and when the rotating component 21 is in the folding state, the third latch 2181 is in snap-fit connection with the fourth latch 2163.

In this embodiment, the second connecting member 216 is sleeved on the outer side of the first connecting member 215, the reset assembly 218 is disposed on the second connecting member 216, and includes two reset buttons 2182 and two second elastic reset members 2183 respectively connected with the two reset buttons 2182, and each reset button 2182 is movably connected on the outer side of the second connecting member 216. A second resilient reset member 2183 is connected between the reset button 2182 and the stop catch plate 2153 on the first connector 215 and has a tendency to return the reset button 2182 to its initial state. By pressing the reset button 2182, the buckling connection between the third buckling member 2181 and the fourth buckling member 2163 can be released, so that the rotating assembly 21 is changed from the folded state to the unfolded state.

Specifically, when the cleaning element 22 is sleeved on the rotating assembly 21, under the action of an external force, the first rotating element 211 and the second rotating element 212 move in opposite directions, the first locking element 2152 and the second locking element 2162 move in the direction away from each other from the original locking state, that is, the first locking element 2152 moves in the direction of the second rotating element 212, and the second locking element 2162 moves in the direction of the first rotating element 211, at this time, the first elastic resetting element 2171 is changed from the first compression state to the second compression state, and the rotating assembly 21 is changed from the expansion state to the contraction state. When the third latch 2181 is connected with the fourth latch 2163, the external force is cancelled, and at this time, the rotating assembly 21 is kept in the folded state due to the latching connection between the third latch 2181 and the fourth latch 2163, so that the cleaning element 22 is conveniently replaced. After the cleaning element 22 is replaced, an external force is applied to the reset button 2182 along the second direction, the reset button 2182 moves towards the connecting component 214 along the second direction, and drives the third latch 2181 to be away from the fourth latch 2163 along the second direction, at this time, due to the existence of the first elastic reset element 2171, the rotating component 21 is converted into an open state from a close state, so that the cleaning operation is convenient to perform. Then, the reset button 2182 is restored to the initial state by the second elastic reset member 2183. By arranging the third fastener 2181 and the fourth fastener 2163, the rotating assembly 21 can be kept in a folded state, so that a user can conveniently vacate two hands to install the cleaning element 22 on the rotating assembly 21. In other embodiments, the reset button 2182 may also be movably connected to the first connecting member 215, in which case the first connecting member 215 is sleeved on the outside of the second connecting member 216, and the second elastic reset member 2183 is connected between the reset button 2182 and the limit catch plate 2153 on the second connecting member 216.

What is different is that, not through the buckle connection between first connecting piece 215 and the second connecting piece 216 for rotating assembly 21 has the state of strutting and receives the state of closing, but through the mode that sets up elasticity piece 217 that resets, makes rotating assembly 21 have the state of strutting under normal condition, and at this moment, elasticity piece 217 that resets can stretch out the state for the nature, also can be for receiving the first compression state of less pressure. When the first rotating member 211 and the second rotating member 212 are close to each other by an external force until the rotating assembly 21 is in the folded state, the elastic restoring member 217 is gradually changed from the first compressed state in which the first rotating member is not stressed or is stressed by a small pressure to the second compressed state in which the first rotating member is stressed by a large pressure. At this time, the elastic reset member 217 generates a large restoring force, and when the external force disappears, the restoring force of the elastic reset member 217 may drive the first rotating member 211 and the second rotating member 212 to be away from each other, so as to restore to the open state, thereby preventing the user from manually resetting. The following description mainly deals with different portions of the second preferred embodiment from the first preferred embodiment, and the same portions are not repeated herein.

By providing the stopper portion 2166, the slide portion 2172 is stopped in the second chute 2165. The length of the opening portion 2167 is the same as that of the receiving groove 2154 in the left and right directions of the head 100, that is, the elastic portion 2173 can be restored to the original state.

When the cleaning element 22 is sleeved on the rotating element 21, under the action of external force, the sliding part 2172 is limited in the second sliding groove 2165 by the limiting part 2166, because the length of the second sliding groove 2165 is greater than that of the accommodating groove 2154 in the left and right directions of the brush head 100, the elastic element is stretched, so that the first rotating element 211 moves towards the direction close to the second rotating element 212, and the rotating element 21 is changed from the expanded state to the retracted state, so that the cleaning element 22 is conveniently sleeved on the rotating element 21.
