Description

Technical Field

[0001] This utility model relates to the field of vacuum cleaner technology, specifically to a cyclone cone filter assembly for vacuum cleaners that prevents filter clogging. Background Technology

[0002] To improve the separation efficiency of dust-laden airflow, vacuum cleaners incorporate a cyclone cone structure on their filter components. This centrifugal force separates the airflow from dust particles. However, in existing vacuum cleaners, the air inlet connecting the cyclone cone structure to its internal cavity is often located at the top. This means that when the airflow from the dust cup enters the filter component, its movement path is limited to a localized area corresponding to the air inlet, leading to frequent filter clogging in that area and affecting usability. Utility Model Content

[0003] The purpose of this utility model is to provide a vacuum cleaner cyclone cone filter assembly that prevents filter clogging, as the air inlet of the existing vacuum cleaner's cyclone cone structure is mostly located at the top, resulting in a small air intake and filtration surface of the filter screen.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: a cyclone cone filter assembly for vacuum cleaners to prevent filter clogging, comprising:

[0005] A filter assembly bracket has a separation chamber in its middle. The bottom of the separation chamber connects to the dust collection chamber inside the lower bracket, and its top connects to the inner cavity of the air outlet at the bottom of the upper bracket.

[0006] The filter screen is fitted onto several support ribs at the edge of the separation chamber on the filter assembly bracket, and its ends are respectively embedded in the positioning grooves on the edges of the upper bracket and the lower bracket.

[0007] The cyclone cone structure includes a bottom cone, a plurality of first guide plates equidistantly arranged along the top edge of the bottom cone, and a second guide plate arranged at the bottom of the first guide plates. The first guide plates abut against the outer surface of the air outlet, and the second guide plates are assembled on the inner concave edge of the lower support. A first air inlet is formed between the ends of adjacent first guide plates, and a second air inlet communicating with the first air inlet is formed between the second guide plate and the bottom cone.

[0008] As a further description of the above technical solution:

[0009] The filter screen is a steel mesh.

[0010] As a further description of the above technical solution:

[0011] The air outlet is divided into multiple air outlet chambers by a partition plate.

[0012] As a further description of the above technical solution:

[0013] The bottom cone, the first guide plate, and the second guide plate are an integral structure.

[0014] As a further description of the above technical solution:

[0015] The first guide plate is an arc-shaped structure spirally arranged on the bottom cone, and the second guide plate is an arc-shaped structure with an L-shaped cross-section, the outer surface of which abuts against the inner side of the support rib.

[0016] As a further description of the above technical solution:

[0017] A baffle plate is mounted on the bottom of the bottom cone via an L-shaped connecting block.

[0018] In summary, by adopting the above technical solution, this utility model has the following advantages over the prior art:

[0019] Beneficial effects:

[0020] The filter assembly of this utility model uses a first guide plate and a second guide plate integrally set with the bottom cone to facilitate the positioning of the cyclone cone structure, the inner concave edge, and the air outlet.

Therefore, they should not be construed as limitations on this utility model.

[0032] Please see Figure 1-6 This utility model provides a technical solution: a cyclone cone filter assembly for vacuum cleaners to prevent filter clogging, comprising:

[0033] The filter assembly bracket 1 has a separation chamber in its middle. The bottom of the separation chamber is connected to the dust collection chamber in the lower bracket, and its top is connected to the inner cavity of the air outlet 7 at the bottom of the upper bracket.

[0034] The filter screen 2 is sleeved on the filter assembly bracket 1 and several support ribs 4 at the edge of the separation chamber, and its ends are respectively embedded in the positioning grooves 5 on the edges of the upper bracket and the lower bracket.

[0035] The cyclone cone structure 3 includes a bottom cone 9, a plurality of first guide plates 10 equidistantly arranged along the top edge of the bottom cone 9, and a second guide plate 12 arranged at the bottom of the first guide plates 10. The first guide plates 10 abut against the outer surface of the air outlet 7, and the second guide plates 12 are assembled on the inner concave edge 6 of the lower support. A first air inlet 11 is formed between the ends of adjacent first guide plates 10, and a second air inlet 13 is formed between the second guide plate 12 and the bottom cone 9, which communicates with the first air inlet 11.

[0036] The filter screen 2 is made of steel mesh to improve filtration efficiency, positioning stability, and service life.

[0037] The air outlet 7 is divided into multiple air outlet chambers by the partition plate 8 to cooperate with different first air inlets 11 to achieve efficient flow and separation of the cyclone cone filter assembly.

[0038] The bottom cone 9, the first guide plate 10, and the second guide plate 12 are integrated into one structure to improve the strength and positioning stability of the cyclone cone structure itself.

[0039] The first guide plate 10 is an arc-shaped structure spirally arranged on the bottom cone 9 to further improve the flow efficiency. The second guide plate 12 is an arc-shaped structure with an L-shaped cross-section, and its outer surface abuts against the inner side of the support rib 4 to further improve the positioning stability of the cyclone cone structure 3.

[0040] The bottom cone 9 is equipped with a baffle plate 14 hanging from the bottom of the L-shaped connecting block to block the airflow at the bottom of the cyclone cone structure 3, so as to prevent it from flowing downward and causing the dust settled at the bottom of the filter component to be stirred up, resulting in poor dust collection efficiency.

[0041] The working principle of a vacuum cleaner cyclone cone filter assembly for preventing filter clogging in this embodiment includes: Compared with the common cyclone cone structure with the inlet located at the top, this filter assembly uses two air inlets arranged at the top and bottom, so that the air inlet surface of the filter assembly can cover the entire filter screen, thereby avoiding the problem of rapid filter clogging; during installation, the first guide plate 10 abuts against the air outlet 7, and the second guide plate 12 abuts against the inner concave edge 6, achieving stable positioning of the cyclone cone structure without the need for a rigid connection with screws; when the filter assembly is in use, the first air inlet 11 and the first guide plate 12... A local airflow is formed at point 0, and another local airflow is formed between the second air inlet 13 and the first air inlet 11. This allows the airflow entering the dust cup to be filtered by the filter screen 2 and enter into it to form the above two local airflows, so as to achieve sufficient flow on the surface of the filter screen 2 and avoid the filter screen 2 from clogging quickly. The two local airflows are filtered by the cyclone filtration effect of the bottom cone 9, and dust and other dirt move down and settle to the bottom of the dust cup. The baffle plate 14 can block the airflow at the bottom of the cyclone cone structure 3 to avoid dust formation and affect dust collection. The clean airflow is drawn out of the dust cup from the air outlet 7.

[0042] In summary, due to the adoption of the above technical solution, the vacuum cleaner cyclone cone filter assembly for preventing filter clogging in this embodiment has the following advantages compared to the prior art:

[0043] The filter assembly of this utility model uses a first guide plate and a second guide plate integrally set with the bottom cone to facilitate the positioning of the cyclone cone structure, the inner concave edge, and the air outlet. In use, the air inlet of the two guide plates allows the air inlet surface of the filter assembly to cover the entire filter screen, thereby avoiding the problem of rapid clogging of the filter screen. The baffle plate at the bottom of the cyclone cone structure can block the airflow at that point, avoid dust problems, and improve dust collection efficiency.

[0044] 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.
