[0027] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0029] See also Figure 1-4 The utility model provides a technical solution: a side clamping structure for a dust cup of a vacuum cleaner that prevents it from falling off, comprising:

[0030] The positioning plate 1 is clamped on the vacuum cleaner base 10 and has a plurality of insertion holes 11 therethrough;

[0031] The dust cup 2 has a snap ring 21 on its side, and the snap ring 21 is correspondingly inserted into the insertion hole 11;

[0032] The locking assembly includes a button 3 that is slidably disposed within a sliding hole 102 on the side of the vacuum cleaner base 10 and a spring 4 that elastically preloads the button 3 outward. The button 3 includes a button body 31, a first clamping block 32 disposed at the top of the button body 31, a limiting plate 34 located on the side of the button body 31, and a positioning structure for docking with the spring 4. The button body 31 is slidably connected to the guide seat 101 of the vacuum cleaner base 10. A block 104 corresponding to the limiting plate 34 is disposed at the opening of the guide seat 101. The first clamping block 32 is correspondingly engaged with the through hole of the snap ring 21. In this embodiment, the cross-sections of the button body 31 and the sliding hole 102 are both parallelograms, which reduce the sliding resistance of the button 3 compared to conventional right-angled or rounded-corner rectangular buttons 3, ensuring that it is effortless to press and has smooth elastic reset. The blocks 104 on both sides of the opening of the guide seat 101 are triangular structures arranged symmetrically around the center, so that the opening also forms a parallelogram structure.

[0033] The side edge of the positioning plate 1 is provided with a snap-on notch 13, which engages with a second latch 103 on the inner side of the vacuum cleaner base 10. A wedge-shaped surface is provided on the inner top of the second latch 103. This design facilitates the pressing and positioning of the positioning plate 1 on the vacuum cleaner base 10, making installation labor-saving and preventing the two from becoming loose.

[0034] The plug-in hole 11 is a T-shaped structure, the outer end of which corresponds to the snap ring 21, and the inner end of which corresponds to the first clamping block 32. This design allows the snap ring 21 to be inserted into the plug-in hole 11. When the first clamping block 32 slides laterally inside the plug-in hole 11, the side walls of the plug-in hole 11 can guide the two stably, ensuring the insertion positioning of the snap ring 21 and the sliding positioning stability of the first clamping block 32, thereby preventing the dust cup 2 from loosening from the locking assembly and ensuring the stability of the dust cup installation.

[0035] The positioning structure includes a cross-shaped spring seat 33 on the inner side of the button body 31 and an arc-shaped guide sleeve 36 on the outer side of the spring seat 33. The end of the spring 4 is sleeved on the spring seat 33, and the inner wall of the arc-shaped guide sleeve 36 abuts against the outer side of the spring 4, thereby ensuring stable axial expansion and contraction deformation of the spring 4 when the button 3 is pressed, thereby ensuring the stability of pressing and resetting the button 3.

[0036] The buttons 3 are arranged in pairs and opposite to each other, and the two opposite buttons 3 share one spring 4 .

[0037] The insertion holes 11 are arranged on both sides of the centrally recessed, arc-shaped positioning plate 1, and an annular guide sleeve 12 extends downward from the outer bottom of the bottom. The inner side of the annular guide sleeve 12 is sleeved on the inner guide block 35 of the button body 31. This design allows the button 3 to be guided not only by the guide seat 101 and the sliding hole 102, but also by the annular guide sleeve 12 and the insertion hole 11 to guide the top of the button 3 and the first clamping block 32, ensuring smooth use of the button and preventing the button 3 from deviating and causing the first clamping block 32 to loosen from the retaining ring 21, the locking assembly, and the dust cup.

[0038] The disassembly and assembly process of the anti-slip side clamping structure of the vacuum cleaner dust cup of this embodiment includes: during installation, the button 3 is slidably assembled in the guide seat 101 and the sliding hole 102, and the spring 4 between the buttons 3 is elastically pre-tightened; the plug-in hole 11 on the positioning plate 1 is connected to the first clamping block 32, and it is pressed into the top of the dust collecting pipe at the front end of the vacuum cleaner base 10, and is locked in position by the second clamping block 103 and the clamping hole 13; the air inlet on the side of the dust cup 2 is sealed with the hole groove structure connected to the dust collecting pipe outlet on the positioning plate 1, and the button 3 is pressed so that the button body 31 is guided by the guide seat 101 and the sliding hole 102, and the first clamping block 32 and the inner guide block 35 are guided by the plug-in hole 11, and slide inward smoothly without lateral deviation, and the snap ring 21 is inserted into the plug-in hole 11, and the button 3 is released, so that the buttons 3 on both sides move outward and reset under the elastic action of the spring 4, and the first clamping block 32 is engaged with the snap ring 21 to complete the assembly of the dust cup 2; when the dust cup is disassembled as a whole, press the buttons 3 on both sides of the vacuum cleaner base 10 to disengage the snap ring 21, and the dust cup 2 can be taken out and the button 3 can be released.

[0039] In summary, due to the adoption of the above technical solution, the anti-drop-off dust cup side clamping structure of this embodiment has the following beneficial effects compared with the prior art:

[0040] The side clamping structure of the dust cup of the utility model realizes the side anti-detachment clamping of the dust cup on the vacuum cleaner through the guide seat, sliding hole, and limit plate for the lateral sliding guidance of the button as a whole, and the T-shaped plug hole for the local sliding guidance of the button of the first clamping block, inner guide block, and clamping ring, thereby ensuring the stable pressing and releasing reset of the button and the high side clamping positioning strength of the dust cup.

[0041] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
