Further, the dust cup 5 and the cleaner housing 1 may be stacked substantially in a depth direction of the dust cup 5, and the dust cup 5 may be snapped to the cleaner housing 1, and the dust separating structure 2 is located in the dust cup 5 and snapped to an end of the cleaner housing 1, so that the dust separated by the dust separating structure 2 may be stored inside the dust cup 5. The air separated by the dust separating structure 2 may pass through the motor 3, and then may further pass through the post-motor filtering structure 4 for filtering, and then is discharged out of the vacuum cleaner 100, so as to prevent secondary pollution to the indoor air.

in this embodiment, as shown in fig. 3, the dust separating structure 2 may include a pressing portion 21, and when the dust separating structure 2 and the cleaner housing 1 are in a clamping state, the pressing portion 21 may contact the cleaner housing 1 to provide a pressing force acting on the cleaner housing 1, so that the cleaner housing 1 and the dust separating structure 2 are relatively fixed; when external acting force acts on the dust collector shell 1 or the dust separation structure 2 and overcomes the pressing force, the dust separation structure 2 and the dust collector shell 1 can be separated, so that a user can clean the dust separation structure 2 conveniently, or when the separation capability of the dust separation structure 2 is poor or even the dust separation function can not be played, the user can replace the dust separation structure conveniently to keep a good dust collection effect of the dust collector 100.

The connection between the dust separating structure 2 and the cleaner housing 1 is mainly realized by clamping the dust separating structure 2 and the cleaner housing 1 and the pressing force of the pressing part 21 acting on the cleaner housing 1.

In an embodiment, as shown in fig. 4 and 5, the dust separating structure 2 may include a first groove 22 concavely formed along a direction away from the dust collector housing 1, and a clamping groove 23 concavely formed by an inner wall of the first groove 22, and the dust collector housing 1 may include a clamping block 11, where the clamping block 11 can cooperate with the clamping groove 23, so as to realize clamping between the dust separating structure 2 and the dust collector housing 1.

For example, as shown in fig. 5, the locking groove 23 may include an insertion portion 231 and a limiting portion 232 communicating with the insertion portion 231, and the limiting portion 232 may include a limiting block 2321 disposed parallel to the bottom surface of the first groove 22; the clamping block 11 can be inserted into the insertion part 231 along the depth direction of the first groove 22, and can slide into the limiting part 232 along the axial direction of the first groove 22, and the limiting block 2321 limits the clamping block 11 along the depth direction of the first groove 22. The insertion part 231 can include a guide surface, and the guide surface can be used for guiding when the clamping block 11 is inserted into the insertion part 231, so that the assembly difficulty is reduced; similarly, the limiting block 2321 may also include a guiding surface to guide when the clamping block 11 moves towards the limiting portion 232.

Specifically, still as shown in fig. 4, the dust separating structure 2 may further include a second groove 24 formed by an inner wall of the first groove 22 being inwardly recessed, and the pressing portion 21 may be rotatably connected to the second groove by a rotating shaft; when the dust separation structure 2 or the cleaner housing 1 is rotated in the axial direction of the first groove 22, a force can be applied to the pressing portion 21 to rotate along the rotation axis and press the pressing portion into the second groove 24, and the pressing portion 21 pressed into the second groove 24 can be kept in contact with the cleaner housing 1 to provide a pressing force for keeping the dust separation structure 2 and the cleaner housing 1 relatively fixed.

In an embodiment, the pressing portion 21 may include a pressing body 211 and an elastic member 212, the pressing body 211 may be rotatably connected to the second groove 24 through a rotating shaft, the elastic member 212 may be disposed on the rotating shaft, and one end of the elastic member 212 abuts against an inner wall of the second groove 24, and the other end abuts against a surface of the pressing body 211 facing the second groove 24, so that during the pressing of the pressing body 21 into the second groove 24, the elastic member 212 is deformed to provide pressing force to the cleaner housing 1, while maintaining a tendency that the pressing body 211 is separated from the second groove 24.

In another embodiment, the pressing portion 21 may be made of an elastic material, and when the vacuum cleaner housing 1 and the dust separating structure 2 are in a separated state, the pressing portion 211 is located in the second groove 24 and has a portion protruding from the inner wall of the first groove 22, so that when the first groove 22 moves circumferentially between the vacuum cleaner housing 1 and the dust separating structure 2, the portion protruding from the inner wall of the first groove 22 is pressed into the second groove 24, and the pressing portion 21 deforms, thereby providing a pressing force.

With respect to the above embodiments, as shown in fig. 6, the dust separating structure 2 may further include a dust separating body 25 and a pre-filtering body 26, and after the airflow separated by the dust separating body 25 is filtered by the pre-filtering body 25 and enters the motor 3, the particles and powder can be prevented from entering the motor 3 to damage the motor 3, wherein the first groove 22 is located on the dust separating body 25, and the pre-filtering body 26 can be clamped in the first groove 22. Wherein, the pre-filtering main body 26 may include a filtering net 261 and an installation part 262 for installing the filtering net 261, and the installation part 262 may be matched with the dust separating main body 25, thereby limiting the pre-filtering main body 25.

Wherein the dust separating body 25 may include a cyclone separator to separate dust from the air flow by a centrifugal force generated by the cyclone separator, the separated dust may be stored in the dust cup 5, the air flow may be sucked by the motor 3 after being filtered by the pre-filtering body 26, and further filtered by the post-motor filtering structure 4. In particular, the cyclone separator may comprise a secondary cyclone separator to improve the separation between the dust and the gas stream.

In one embodiment, the shape of the mounting portion 262 may be matched to the shape of the first recess 22, and the mounting portion 262 and the first recess 22 may be a tight fit to achieve the retention of the pre-filter body 25.

In another embodiment, still shown in fig. 6, the dust separating body 25 may include a third groove 251 formed by inwardly recessing the vertical wall surrounding the first groove 22, and the mounting portion 262 may include a mounting protrusion 2621 cooperating with the third groove 251, so that the pre-filter body 26 is restrained by the cooperation between the mounting protrusion 2621 and the third groove 251.

In another embodiment, when there is a contact portion between the surface of the pre-filter body 26 and the pressing portion 21, the pre-filter body 26 may also be limited inside the first groove 22 by the force provided by the pressing portion 21.

It should be noted that: when the pre-filter body 26 and the cleaner case 1 have a portion contacting the pressing portion 21, respectively, the pressing portion 21 is pressed into the second recess 24 by a previously assembled component, and a subsequently assembled component can be assembled to the dust separating body 25 after overcoming the pressing force provided by the pressing portion 21. For example, when the cleaner housing 1 is assembled first, the cleaner housing 1 may press the pressing portion 21 into the second groove 24; when the pre-filter body 26 is assembled first, the pressing part 21 may be pressed into the second groove 24 by the pre-filter body 26, although the pressing part 21 may not rotate relative to the second groove 24 when the cleaner housing 1 is assembled later, it should be understood that the cleaner housing 1 still has the ability to rotate the pressing part 21 relative to the second groove 24.
