[0053] The inlet of this handheld vacuum cleaner is modularly connected to the dust collection pipe via a first connecting seat, a second connecting seat arranged internally and externally. This ensures assembly strength and ease of assembly and disassembly, while also diversifying the assembly methods. During assembly, the first connecting seat is first installed inside the dust collection pipe connector. Then, the second and third connecting seats can be connected first and then installed on the dust collection pipe connector. Alternatively, the second connecting seat can be positioned on the dust collection pipe connector first, and then the third connecting seat can be connected to other accessories. Disassembly is performed by reversing the above steps, resulting in diverse methods and improved applicability.

Several first locking blocks 53 are provided on the outer side of the spring block 52, and the first locking blocks 53 are correspondingly engaged with the bayonet 31 of the first connecting seat 3. When the third connecting seat 5 is connected to the first connecting seat 3, after the insertion tube 51 is inserted into the first connecting seat 3, the spring block 52 is compressed and rotates inward until the first locking block 53 is aligned and engaged with the bayonet 31. At this time, the structure elastically resets, and the sealing ring at the inner end of the dust collection tube 50 is sealed and joined with the sealing ring in the dust collection tube connector 12 and the first connecting seat 3. When the structure is disassembled, the spring block 52 is compressed and flipped inward, which unlocks the first locking block 53 from the bayonet 31, and the third connecting seat 5 can be removed.

Several insertion rods 45 are circumferentially arranged on the outer end face of the second connecting seat 4, and the insertion rods 45 are inserted into the first slot 54 of the third connecting seat 5. When the second connecting seat 4 is connected to the dust collection pipe connector 12, the first pressing block 42 is pressed first, causing the second locking block 44 to move outward, thus placing the second connecting seat 4 onto the dust collection pipe connector 12. Then, the first pressing block 42 can be released, achieving structural locking. At this time, the second connecting seat 4 and the mating surface 14 are tightly fitted. When the second connecting seat 4 is connected to the third connecting seat 5, the two are first aligned to ensure that the wedge-shaped end faces are parallel. Then, the two are axially inserted, allowing the insertion rods 45 to be inserted and positioned into the first slot 54, with the wedge-shaped end faces tightly fitted. Disassembly is performed by reversing the above steps.
