[0048] The dust cup 3 is mounted in the dust cup groove 12 of the vacuum cleaner body 1, the dust cup air inlet 31 on the dust cup 3 is connected to the end of the ventilation pipe 13, and the dust cup air outlet 32 ​​on the dust cup 3 is connected to the motor through the air outlet channel 14 on the dust cup groove 12;

[0049] The dust cup limiting mechanism includes a chassis structure 5 supported at the bottom of the dust cup 3 and a top kit 4 sleeved on the dust cup 3, the top kit 4 is rotatably connected to the top of the dust cup groove 12 through a rotating block 41, the chassis structure 5 is hinged at the bottom front end of the dust cup groove 12, and a first support rod 6 and a second support rod 7 are hinged between the top kit 4 and the chassis structure 5, respectively, and the ends of the first support rod 6 and the second support rod 7 are correspondingly spliced ​​and magnetically positioned.

[0050] The vacuum cleaner of the present invention is a mobile vacuum cleaner with movable wheels and modularly assembled parts. The air inlet component and the dust cup are conveniently detachable, and the dust cup limiting mechanism is foldable and retractable on the vacuum cleaner body and the host, so that the size of the vacuum cleaner when disassembled can be further reduced to facilitate the storage and transportation of the vacuum cleaner. After the dust cup limiting mechanism is unfolded, the top kit and the chassis structure can form a bottom support and top limiting effect on the dust cup to ensure the installation stability and the tightness of the air duct docking. The top kit and the chassis structure are structurally supported and positioned by two hinged and retractable support rods, and the surface of the dust cup is further limited. The two support rods are magnetically connected to ensure the convenience of disassembly and assembly, and can also achieve magnetic pre-tightening. Compared with the clamping and bolt assembly methods, it can avoid the loosening of the structure caused by the vibration of the vacuum cleaner operation.

[0051] The air inlet assembly 2 is a Y-shaped structure, and the butt ends on both sides thereof are sleeved on both sides of the vacuum cleaner body 1. A plurality of hooks 21 are provided at circumferential intervals at the edges of the butt ends, and the hooks 21 are correspondingly clamped on the clamping grooves 111 of the mounting seat 11. Magnets 112 are provided on the butt ends and the mounting seat 11, and the butt ends are magnetically pre-tightened and positioned with the mounting seat 11. The air inlet assembly 2 ensures the convenience of assembly and disassembly and the structural stability after positioning through multiple positioning methods such as sleeve connection at both ends, clamping, and magnetic docking. The Y-shaped structural design also makes it easy to open the ends of the air inlet assembly 2 and sleeve them on the vacuum cleaner, thereby improving the convenience of use.

[0052] The top of the dust cup 3 is in a truncated cone shape to cooperate with the top kit 4 to ensure stable positioning of the top of the dust cup 3. The outer side of the bottom surface of the dust cup groove 12 is tilted upward so that the dust cup 3 is tiltedly assembled on the vacuum cleaner to fully support and limit it.

In addition, after the top kit 4 and the chassis structure 5 are stored, magnets are also provided between the two and at the joints with the vacuum cleaner body 1. Based on the fact that the dust cup limit mechanism can be stored, this design deepens the design of the structural positioning strength of the dust cup in the stored state. By magnetically docking the adjacent structures in this state, the structural positioning is stable to avoid collision and wear problems.

[0055] A first mating surface 61 is arranged at the end of the first support rod 6, a second mating surface 62 is extended from the side of the first mating surface 61, and a third mating surface 71 and a fourth mating surface 72 corresponding to the first mating surface 61 and the second mating surface 62 are arranged at the end of the second support rod 7, respectively, to ensure the positioning stability of the structure when the dust cup limiting mechanism is in the unfolded and stored states.

The chassis structure 5 is provided with an insert block 121 which is engaged with the slot at the bottom of the dust cup 3, and is also provided with a plurality of concentric arc convex ribs 122 which are coaxially arranged with the dust cup 3, so as to improve the limiting performance of the dust cup limiting mechanism on the dust cup.

[0057] The bottom of the vacuum cleaner body 1 is also equipped with a moving wheel assembly 8, on which a wheel 81 is arranged. The positioning block 16 at the bottom of the vacuum cleaner body 1 is inserted and clamped on the moving wheel assembly 8, and a plurality of reinforcing spokes 161 are arranged at intervals along the circumference of the surface of the positioning block 16, so as to further reduce the size of the integrated structure of the vacuum cleaner body 1.

[0058] A protrusion 15 is provided at the front end of the bottom of the vacuum cleaner body 1 , and the protrusion 15 is correspondingly matched with the notch on the side of the chassis structure 5 , so as to further improve the stability of the chassis structure 5 when it is unfolded.

[0059] The disassembly and assembly process of a modularly assembled vacuum cleaner of this embodiment includes: when disassembling the vacuum cleaner, first open and disassemble the air inlet assembly 2; turn the first support rod 6 and the second support rod 7 outward, and turn the top kit 4 out from the surface of the dust cup 3, then hold the U-shaped gripper 33 to take out the dust cup 3, and then remove the moving wheel assembly 8; the two support rods are respectively turned over and stored to the inside of the top kit 4 and the chassis structure 5, and the adjacent first support rods 6 (second support rods 7) are spliced ​​and magnetically positioned, and the top kit 4 and the chassis structure 5 are turned over to one side of the vacuum cleaner body 1 and magnetically positioned, that is, the modular disassembly of the structure is completed and the structure is minimized for easy storage. When assembling the vacuum cleaner, the above disassembly steps can be performed in reverse order.
