Description

[Technical Field]

[0001] The present invention relates to a dust filtering and suction tube. [Background technology]

[0002] As described in Chinese Patent No. 106725100, when using a vacuum cleaner in daily life, various types of suction heads are used to accommodate different usage environments. For example, different suction heads are used depending on the type of object to be vacuumed. For example, when cleaning cat litter, it is desirable to vacuum up small particles but not the cat litter itself.

[0003] However, when cleaning, the suction power of a vacuum cleaner is so strong that it often sucks up large and small particles together, making it impossible to filter out the small particles. On the other hand, if a user manually installs a filter on a conventional vacuum cleaner, the particles sucked in by the strong suction power of the vacuum cleaner tend to accumulate on the filter or become clogged, which requires frequent cleaning of the filter or frequent power-on / off of the vacuum cleaner during use, resulting in great inconvenience.

[0004] In view of the above problems, providing better means for improvement has become an urgent issue in this technical field. Summary of the Invention [Problem to be solved by the invention]

[0015] 1 to 3, the present invention proposes a dust filtering and suction tube that includes an adjustment joint 10 and a dust collection tube 20, and may or may not include an airflow blocking plate 30. In this embodiment, the adjustment joint 10 and the dust collection tube 20 are integrally molded, but in other embodiments, the adjustment joint 10 and the dust collection tube 20 may be detachably attached.

[0016] The adjustment joint 10 can be connected to a vacuum cleaner and is used to adjust the suction force for sucking dust from the dust collection cylinder 20 into the dust filtering suction cylinder. The dust collection cylinder 20 is cylindrical, with one end connected to the adjustment joint 10. The airflow blocking plate 30 is connected to the dust collection cylinder 20, and the adjustment joint 10, dust collection cylinder 20, and airflow blocking plate 30 are connected to one another. In this embodiment, the airflow blocking plate 30 is located at the boundary between the adjustment joint 10 and the dust collection cylinder 20, but the location of the airflow blocking plate 30 is not limited to this and it may be located inside the dust collection cylinder 20 or inside the adjustment joint 10.

[0017] As shown in Figures 4, 7, 8 and 11, adjustment joint 10 has air inlet 11 and adjustment member 12. Air inlet 11 is provided on the side wall of adjustment joint 10. When vacuuming, air flows in through air inlet 11, reducing the amount of air flowing in from dust collection canister 20. Adjustment member 12 can selectively block air inlet 11, thereby adjusting the amount of air flowing in from air inlet 11 and thereby adjusting the suction power of dust collection canister 20.

[0018] 5 and 6, dust collection cylinder 20 has an internal space, first opening 21, second opening 22, engagement groove 23, at least one filter 24, and multiple protrusions 25, and the internal space connects airflow blocking plate 30 and adjustment joint 10. First opening 21 and second opening 22 are both provided at one end of dust collection cylinder 20 remote from adjustment joint 10 and communicate with the internal space. Second opening 22 is cone-shaped, and the tip of cone-shaped second opening 22 protrudes in a direction away from first opening 21. In this embodiment, the first opening 21 and the second opening 22 are separated by a partition plate, but in other embodiments, the first opening 21 and the second opening 22 may be connected without providing the partition plate. Furthermore, in this embodiment, the shape of the first opening 21 is circular, but in other embodiments, there is no limitation on the shape of the first opening 21, and the second opening 22 does not necessarily have to be provided.

[0019] The engagement groove 23 and at least one filter 24 are both provided at one end of the dust collection tube 20 remote from the adjustment joint 10, and the filter 24 can be provided in the engagement groove 23 to block the first opening 21 or the second opening 22, thereby separating dust particles of different sizes. In this embodiment, filters 24 of corresponding shapes can be provided for the first opening 21 and the second opening 22, and in this embodiment, multiple protrusions 25 are provided at the end of the dust collection tube 20 close to the adjustment joint 10 and protrude toward the adjustment joint 10.

[0020] As shown in FIGS. 9 and 10 , the airflow blocking plate 30 has a conical protrusion 31, multiple filtering holes 32, and multiple through-holes 33. The conical protrusion 31 is located on the connecting surface of the airflow blocking plate 30 with the dust collection tube 20 and protrudes toward the dust collection tube 20, thereby increasing wind resistance and reducing the suction force in the dust collection tube 20. The multiple filtering holes 32 penetrate the airflow blocking plate 30 and allow only fine dust particles to pass through. In this embodiment, the filtering holes 32 are positioned to surround the conical protrusion 31. However, in other embodiments, the airflow blocking plate 30 may not have the conical protrusion 31 and the filtering holes 32 may be evenly distributed on the airflow blocking plate 30. Alternatively, the through-holes 33 may be located near the edge of the airflow blocking plate 30 and positioned to correspond to the protrusions 25 of the dust collection tube 20. The protrusions 25 may be engaged with the through-holes 33 to secure the airflow blocking plate 30.

[0021] 12 and 13, when using the dust filter suction tube, the amount of air drawn into the air inlet 11 is adjusted using the adjustment member 12. The smaller the area of ​​the air inlet 11 that is blocked by the adjustment member 12, the greater the amount of air drawn into the air inlet 11. Therefore, for the same suction power of the vacuum cleaner, the less air flows into the dust collection tube 20, and the suction power at the first opening 21 and the second opening 22 during use can be reduced. According to this method, when cleaning corners of the container or areas that require a smaller suction head, the cone-shaped second opening 22 can be used for cleaning, and the cone-shaped second opening 22 makes it easier to use.

[0022] The advantage of the present invention is that by adding at least one filter 24 to the end of the dust collection tube 20, the dust filter suction tube can be replaced depending on the usage situation, allowing it to filter dust of different particle sizes. Furthermore, by adding the air intake 11 and adjustment member 12 to the adjustment joint 10, the suction power can be adjusted when using the dust filter suction tube, solving the problem of large and small particles being sucked in together due to the vacuum cleaner's suction power being too strong. Furthermore, by adding the cone-shaped second opening 22, it can be fitted more closely to the corners of a container or wall, allowing users to use it in a variety of environments.
