[0028] See Figures 1-4 , this utility model provides a vacuum cleaner facilitating the disassembly and assembly of a dust cup, including a machine body 1 and a dust cup 2. An insertion interface 11 is provided on the machine body 1, and the dust cup 2 is inserted into the insertion interface 11. A rotating ring 3 is sleeved on the outer peripheral wall of the dust cup 2. A first locking structure is provided on the rotating ring 3, and a second locking structure is provided on the machine body 1. The rotating ring 3 can rotate relative to the dust cup 2 to lock or unlock the first locking structure and the second locking structure. When the dust cup 2 needs to be installed, the dust cup 2 is inserted into the insertion interface 11 of the machine body 1, and then the rotating ring 3 is rotated so that the rotating ring 3 is locked on the machine body 1, thereby locking the dust cup 2 on the machine body 1. When the dust cup 2 needs to be disassembled, the rotating ring 3 is rotated in the reverse direction so that the rotating ring 3 is unlocked from the machine body 1, and thus the dust cup 2 can be disassembled from the machine body 1. The locking or unlocking of the dust cup 2 can be achieved by rotating the rotating ring 3. The structure is simple, and there is no need to additionally provide an unlocking member for unlocking the dust cup 2, which is beneficial to reducing the volume of the vacuum cleaner and can also facilitate the disassembly and assembly of the dust cup 2 and improve the efficiency of disassembly and assembly.

[0029] Further, the first locking structure includes a connecting portion 31 and a buckle 32 extending along the circumferential direction of the swivel ring 3. The two ends of the connecting portion 31 are respectively connected to the outer peripheral wall of the swivel ring 3 and the buckle 32. The body 1 is a hollow structure, and the second locking structure is a clamping hole 12 provided on the body 1. After the buckle 32 extends into the clamping hole 12, the swivel ring 3 can be rotated so that the buckle 32 abuts against the inner wall of the body 1. When the dust cup 2 needs to be installed, the dust cup 2 is inserted into the insertion port 11 of the body 1, and then the swivel ring 3 is rotated in the extending direction of the buckle 32. The swivel ring 3 drives the buckle 32 to rotate, so that the buckle 32 abuts against the inner wall of the body 1, thereby locking the dust cup 2 on the body 1 in the horizontal direction; when the dust cup 2 needs to be disassembled, the swivel ring 3 is rotated in the direction opposite to the extending direction of the buckle 32. The swivel ring 3 drives the buckle 32 to rotate in the opposite direction, so that the buckle 32 returns to the position corresponding to the clamping hole 12, so that the buckle 32 can be disengaged from the clamping hole 12, realizing the separation of the swivel ring 3 and the body 1, and thus the dust cup 2 can be unlocked and disassembled from the body 1. By rotating the swivel ring 3, the locking or unlocking of the dust cup 2 can be realized. The structure is simple and is conducive to the quick disassembly and assembly of the dust cup 2.

[0030] Further, a first limiting rib 321 is provided on the inner side wall of the buckle 32, and a second limiting rib is provided on the inner wall of the body 1. The first limiting rib 321 abuts against the second limiting rib to prevent the buckle 32 from disengaging from the clamping hole 12. Both the first limiting rib 321 and the second limiting rib are vertically arranged. When the dust cup 2 is locked on the body 1, the first limiting rib 321 abuts against the second limiting rib, thereby restricting the reverse unlocking rotation of the swivel ring 3 and preventing the swivel ring 3 from accidentally rotating in the reverse direction during the movement of the vacuum cleaner, causing the dust cup 2 to fall off.

[0031] Further, an annular groove is provided on the outer peripheral wall of the dust cup 2, and the swivel ring 3 is sleeved in the annular groove. The swivel ring 3 is embedded in the dust cup 2, which is conducive to reducing the volume of the dust cup 2.

[0032] Further, the outer peripheral wall of the swivel ring 3 is flush with the outer peripheral wall of the dust cup 2, and there is no need to additionally provide an avoidance groove on the body for accommodating the swivel ring 3, which is conducive to making the structure of the vacuum cleaner more compact and conducive to the production of miniaturized machines.

[0033] Further, a plurality of anti-slip grooves 33 are provided on the outer peripheral wall of the swivel ring 3, which can increase the surface friction of the swivel ring 3 and facilitate the control of the rotation of the swivel ring 3.

[0034] Further, a sealing edge 13 is provided on the body 1, and the dust cup 2 is sleeved on the sealing edge 13. The dust cup 2 is communicated with the body 1 to realize the flow of air.

[0035] Further, a convex block 131 is provided on the outer peripheral wall of the edge seal 13, and a connection hole 21 is provided on the dust cup 2. The convex block 131 is snapped into the connection hole 21, and the convex block 131 is provided at the lower edge of the outer peripheral wall of the edge seal 13. The dust cup 2 is sleeved on the edge seal 13 from bottom to top, and the convex block 131 is snapped into the connection hole 21 to lock the dust cup 2 in the vertical direction and prevent the dust cup 2 from falling downward. It should be understood that when the dust cup 2 is inserted into the insertion port 11 of the machine body 1, the air inlet end of the dust cup 2 is synchronously sleeved on the edge seal 13. When the dust cup 2 is completely inserted into the insertion port 11, the convex block 131 and the connection hole 21 are snapped together, and the dust cup 2 is locked in the vertical direction. Then, the rotary ring 3 is rotated, and the rotary ring 3 drives the buckle 32 to rotate, so that the buckle 32 abuts against the inner wall of the machine body 1, thereby locking the dust cup 2 on the machine body 1 in the horizontal direction, and finally achieving multi-directional locking. When the dust cup 2 needs to be disassembled, the rotary ring 3 is rotated in the reverse direction, and the rotary ring 3 drives the buckle 32 to rotate in the reverse direction, so that the buckle 32 returns to the position corresponding to the locking hole 12, so that the buckle 32 can be disengaged from the locking hole 12, realizing the separation of the rotary ring 3 from the machine body 1. Then, a downward force is applied to the dust cup 2, so that the convex block 131 is separated from the connection hole 21, thereby unlocking and disassembling the dust cup 2 from the machine body 1. Further, the bottom wall of the convex block 131 is a guiding wall that gradually inclines inward toward the dust cup 2. The guiding wall is used to guide the convex block 131 to insert into the connection hole 21, so that the dust cup 2 can be quickly installed on the machine body 1.

[0036] Further, the width of the locking hole 12 is greater than the width of the buckle 32, which facilitates the buckle 32 to be disengaged from the locking hole 12.

[0037] Further, a first air inlet 14 is provided on the side wall of the machine body 1, and a second air inlet 22 is provided on the side wall of the dust cup 2. The first air inlet 14, the second air inlet 22, and the insertion port 11 communicate to form a first air duct. The first channel is a dust suction channel. Dust follows the airflow and enters the interior of the dust cup 2 through the first air inlet 14 and the second air inlet 22 in sequence for filtration. The dust is left inside the dust cup 2, and the airflow filtered by the dust flows back to the machine body 1 from the insertion port 11 and is finally exhausted outward. It should be understood that the bottom of the dust cup 2 has an end cover, and opening the end cover can pour out the dust inside the dust cup 2.

[0038] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the protection scope of the invention.
