[0031] Please see Figure 1-5 This utility model provides a technical solution: a multi-locking structure for a concealed dust cup cover of a vacuum cleaner, comprising:

[0032] Dust cup cover 1 is embedded in the countersunk positioning opening 110 on the end face of dust cup 100. One side of it is hinged to the dust cup 100, and the other side extends laterally with an extension block 2. The inner end face of the extension block 2 extends toward the dust cup 100 with a hook 3.

[0033] The latch 4 is rotatably connected to the movable groove 120 of the dust cup 100 via the rotating shafts 5 on both sides. One end of the movable groove 120 is connected to the countersunk positioning port 110. One end of the latch 4 is provided with a latch 6, and the hook 3 engages with the latch 6. The other end of the latch 4 is provided with a pointed block 7, which extends from the other end of the movable groove 120 to the outside of the dust cup 100. An elastic element 8 is provided between the other end of the latch 4 and the movable groove 120.

[0034] The first magnet 9 and the second magnet 10 are respectively positioned on the extension block 2 and the movable groove 120, and the first magnet 9 and the second magnet 10 are magnetically connected.

[0035] A support block 11 is provided inside the movable groove 120. The support block 11 abuts against the latch 6, and the inclination angle of its end wedge-shaped surface is the same as the inclination angle of the latch 6 surface when the hook 3 and the latch 6 are engaged and locked. This ensures that when one end of the latch 4 is pushed out by the elastic element 8 and the hook 3 at the other end is engaged with the latch 6, the support block 11 can be stably assembled and supported on the latch 6, thus ensuring the structural positioning of the latch 4 and the stability of the engagement between the hook 3 and the latch 6.

[0036] The elastic element 8 is a compression spring. A limiting post 12 is provided on the inner side of the other end of the latch 4, and one end of the elastic element 8 is fitted and positioned on the limiting post 12. A limiting plate 13 is provided in the movable groove 120, and the other end of the elastic element 8 is swayably fitted on the limiting plate 13. This allows the end of the elastic element 8 to stably engage with the limiting post 12 and the limiting plate 13 respectively when the latch 4 rotates.

[0037] The first magnet 9 and the second magnet 10 are respectively embedded in the positioning frame 14 positioned on the extension block 2 and the movable groove 120.

[0038] The working principle of the multi-locking structure of the dust cup cover of the concealed vacuum cleaner in this embodiment includes: During use, pressing the pointed block 7 causes the latch 4 to rotate along the rotating shaft 5, disengaging the latch 6 from the hook 3. Then, through the magnetic repulsion force formed by the two magnets, the dust cup cover 1 flips along the dust cup 100, opening the inner cavity of the dust cup 100. Specifically, as shown... Figure 5 As shown; when the dust cup cover 1 is closed, it is pressed into the countersunk positioning port 110. Then, the lock 4 can be released, so that the pointed block 7 moves out of the movable groove 120 under the elastic force of the elastic element 8. The latch 6 engages with the hook 3 to achieve the locking and positioning of the dust cup cover 1.

[0039] In summary, due to the adoption of the above technical solution, the multi-locking structure of the concealed dust cup cover of the vacuum cleaner in this embodiment has the following advantages compared with the prior art:

[0040] This utility model's dust cup lid features a multi-locking structure. It uses hooks and latches for locking, and the magnetic repulsion of a magnet achieves pre-tightening of the structure and ejection of the dust cup lid after unlocking. This multi-locking positioning and convenient opening of the dust cup lid are achieved. The structure is evenly distributed inside the dust cup, extending only to the outside via a pointed block, facilitating pressing and driving of the locking mechanism. The portion of this structure exposed outside the dust cup is minimal, thus achieving a concealed design and preventing accidental opening. The dust cup lid is also fully embedded in a countersunk positioning opening, further enhancing its aesthetics and reducing the impact of external shocks, thus improving its lifespan and positioning stability.

[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
