[0034] Please see Figure 1-5 This utility model provides a technical solution: a handheld vacuum cleaner with a quick-assembly filter assembly, comprising:

[0035] The vacuum cleaner body 1 has a partition 2 that separates the dust chamber and the motor chamber in its inner cavity, and a flow mesh plate is provided on the partition 2;

[0036] The filter assembly includes a base 4, a cyclone cone structure 5, a first HEPA filter bracket 6, a connecting seat 7, and a second HEPA filter bracket 8. A filter screen is fitted on the base 4. The bottom edge of the cyclone cone structure 5 is inserted into the dust collection cone 41 of the base 4. The air outlet 61 in the middle of the first HEPA filter bracket 6 extends downward into the cyclone cone structure 5. Its bottom edge is fitted onto the top of the base 4 and is engaged with the locking block 42 of the base 4 through the inner wall of the retainer 62 on its bottom edge. Its top edge is inserted into the connecting seat 7 and is connected to the sliding groove 71 on the inner wall of the connecting seat 7 through the sliding positioning block 63 on its surface. The second threaded sleeve 72 on the connecting seat 7 is connected to the first threaded sleeve 21 at the bottom of the partition 2 and is positioned by bolts. The second HEPA filter bracket 8 is inserted into the first HEPA filter bracket 6. The first HEPA filter and the second HEPA filter are respectively arranged inside the first and second HEPA filters.

[0037] The vacuum cleaner body 1 and the partition 2 are an integral structure. This, combined with the positioning and assembly method of the filter assembly and the partition 2, ensures that the filter assembly is associated with the vacuum cleaner body 1, improving positioning strength.

[0038] The partition 2 is also provided with an annular insert 22, which is inserted into the sleeve 73 at the top of the connecting seat 7. This allows for structural guidance when the connecting seat 7 is assembled on the partition 2 and the second threaded sleeve 72 mates with the first threaded sleeve 21, and also allows for structural pre-tightening and pre-positioning through the annular sleeve structure.

[0039] The partition 2 is provided with circumferential ribs on the outside of the annular insert 22, and the circumferential ribs are joined with the notches on the radial ribs on the top surface of the connecting seat 7.

[0040] The bottom edge of the cyclone cone structure 5 extends downward with an inner retaining ring 51 and an outer retaining ring 52. The inner retaining ring 51 is inserted into the inner wall of the dust collection cone 41, and the outer retaining ring 52 is embedded in the retaining groove 43 on the outer side of the top surface of the dust collection cone 41. This improves the positioning strength between the cyclone cone structure 5 and the base 4.

[0041] The top edge of the cyclone cone structure 5 is provided with several internal air inlet units. Each internal air inlet unit includes an outer first side plate 53, a second side plate 54 spirally arranged along the inner wall of the cyclone cone structure 5, and an inclined top plate 55. The first side plate 53, the second side plate 54, and the top plate 55 are all arc-shaped plates and are an integral structure. The three form an air inlet 56 with a cross-sectional size that gradually increases along the airflow direction, so as to improve the structural strength of the air inlet of the cyclone cone structure 5 and ensure the stability of the airflow.

[0042] The groove 71 is an L-shaped groove, and the width of its inlet is equal to the length of the sliding positioning block 63, which improves the ease of docking between the two.

[0043] The top of the first HEPA filter bracket 6 and the bottom of the second HEPA filter bracket 8 are evenly distributed with countersunk holes. The first and second HEPA filters are embedded in the corresponding countersunk holes. The bottom edge of the second HEPA filter bracket 8 abuts against the first HEPA filter inside the first HEPA filter bracket 6, and its top extends out of the first HEPA filter bracket 6 and is provided with a handle groove. The two HEPA filters are assembled in the grooves on the opposite surfaces of the two HEPA filter brackets, and the positioning of the two HEPA filters is achieved through the positioning of the HEPA filter brackets. The handle groove is provided to facilitate the gripping of the second HEPA filter bracket 8, thereby making the assembly of the two HEPA filter brackets convenient.

[0044] The assembly process of a handheld vacuum cleaner with a quick-assembly filter assembly according to this embodiment includes: first, assembling and shaping the vacuum cleaner body 1; the inner retaining ring 51 and outer retaining ring 52 of the cyclone cone structure 5 are inserted and positioned with the inner wall of the top of the dust collection cone 41 of the base 4 and the slot 43; a filter screen is fitted on the base 4; the first HEPA bracket 6 is fitted on the top of the base 4 and positioned by the retaining sleeve 62 and the retaining block 42; the air outlet 61 is inserted into the cyclone cone structure 5 and abuts against the top of the cyclone cone structure 5 through its outer structure to position the cyclone cone structure 5; the first HEPA is arranged in the countersunk hole at the top of the first HEPA bracket 6, and the second HEPA is arranged in the countersunk hole at the bottom of the second HEPA bracket 8; then the second HEPA bracket 8 is inserted... The first HEPA filter bracket 6 is inserted into the dust chamber to position the two HEPA filters. The connecting seat 7 is inserted into the dust chamber and is connected to the insert sleeve 73 through the annular insert 22 and the protruding ribs abut against each other to pre-position the connecting seat 7 and the partition plate 2. At the same time, the first threaded sleeve 21 abuts against the second threaded sleeve 72 and is fixed with bolts. The assembled first HEPA filter bracket 6 is inserted into the dust chamber and into the inner wall of the connecting seat 7. The sliding positioning block 63 is connected to the inlet of the slide groove 71 and is inserted further in. After it reaches the bottom, the first HEPA filter bracket 6 is rotated so that the sliding positioning block 63 is positioned at the end of the slide groove 71. Then the dust cup cover can be closed to support and position the bottom of the filter assembly, thereby achieving rapid and stable assembly of the filter assembly.

[0045] In summary, due to the adoption of the above technical solution, the handheld vacuum cleaner with quick-assembly of the filter component in this embodiment has the following advantages compared with the prior art:

[0046] In this handheld vacuum cleaner, the filter assembly is mounted on a partition integrally formed with the main body of the vacuum cleaner, thereby establishing a connection between the filter assembly and the main body and improving assembly strength. The inner and outer retaining rings at the bottom of the cyclone cone structure enhance the ease of positioning with the base.
