Description

Technical Field

[0001] This utility model belongs to the field of vacuum cleaner technology, and in particular relates to an isolated dust cup ash storage structure. Background Technology

[0002] A vacuum cleaner is a household appliance that uses the principle of air pressure difference for cleaning. Its core is to use a motor to drive a fan to rotate, creating negative pressure inside a sealed casing, thereby sucking in dust and debris.

[0003] Currently, some vacuum cleaners on the market use an integrated dust cup design, which cannot separate coarse and fine dust particles. While this structure simplifies the container's form, it reveals significant limitations in actual use: when the vacuum cleaner sucks in mixed waste, fine particles are easily re-entrained by airflow turbulence, reducing cleaning efficiency and being released back into the air through the exhaust system, exacerbating indoor dust pollution and posing a health hazard to people with respiratory sensitivities. Furthermore, the mixed dust collection mode increases the difficulty of cleaning—coarse and fine particles require repeated emptying and shaking to separate, and fine dust easily adheres to the inner wall of the dust cup, making cleaning tedious and leaving residue. Over time, bacteria can easily grow on the inner wall of the dust cup, creating unsanitary areas. Utility Model Content

[0004] The purpose of this utility model is to address the problem that some vacuum cleaners on the market use an integrated dust collection design, which cannot separate coarse and fine particles, causing fine particles to be easily re-spread under airflow disturbance, affecting cleaning efficiency and making subsequent cleaning difficult. Therefore, this utility model proposes an isolated dust collection structure.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an isolated dust cup ash storage structure, comprising:

[0006] The dust cup body is mounted on the rear side of the vacuum cleaner main unit, and the bottom of the dust cup body is connected to the suction pipe outlet;

[0007] The dust cup contains a filter screen, which is located inside the dust cup. The filter screen is equipped with a dust guide, and a fine particle dust collection cylinder is connected to the dust guide. The dust cup and the filter screen form a coarse particle dust collection space.

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

[0009] The dust guide component is a cyclone cone.

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

[0011] The dust cup body is provided with a sealing groove, one end of the dust cup cover is rotatably connected to the sealing groove, and the other end is connected to the sealing groove through a button.

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

[0013] The dust cup body is provided with a rotating groove, and a rotating shaft is provided in the rotating groove. The dust cup cover is provided with a connecting ear, and the rotating shaft is connected to the connecting ear. A torsion spring is sleeved on the rotating shaft, with one end of the torsion spring connected to the dust cup cover and the other end connected to the inner wall of the rotating groove.

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

[0015] The button component includes a button and a spring. The dust cup body is provided with a mounting groove, and a limit post and a fulcrum plate are provided in the mounting groove. The dust cup cover is provided with a locking block. The spring is connected to the limit post. The button is provided with a locking body, and the fulcrum plate is located on one side of the locking body.

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

[0017] The fine particle ash storage cylinder is provided with a limiting shaft and a snap-fit ​​groove. One side of the sealing cover is connected to the limiting shaft, and the other side is snapped into the snap-fit ​​groove.

[0018] As a further description of the above technical solution:

[0019] The fine-particle ash storage cylinder is equipped with an outwardly expanding ash guide ring plate.

[0020] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0021] In this invention, a filter screen is installed inside the dust cup, with a cyclone cone inside the filter screen and a fine particle dust collection cylinder on the cyclone cone. The space between the dust cup and the filter screen forms a coarse particle dust collection space. When vacuuming, dust enters from the suction pipe and is guided into the dust cup. Fine dust particles slowly settle into the fine particle dust collection cylinder through the cyclone cone in the filter screen, while coarse dust particles are intercepted outside the filter screen and located in the coarse particle dust collection space. This structure avoids secondary dust generation of fine dust particles, greatly improving cleaning efficiency. When cleaning, simply open the dust cup cover and the sealing cover to clean them separately, without the need for tapping or banging, thus improving the user experience. Attached Figure Description

[0046] Working principle: By installing a filter screen inside the dust cup, with a cyclone cone inside the filter screen and a fine particle collection cylinder on the cyclone cone, a coarse particle collection space is formed between the dust cup body and the filter screen. When vacuuming, dust enters from the suction pipe and is guided into the dust cup. Fine dust particles slowly settle into the fine particle collection cylinder through the cyclone cone in the filter screen, while coarse dust particles are intercepted outside the filter screen and located in the coarse particle collection space. This structure avoids secondary dust re-entrainment of fine dust particles, greatly improving cleaning efficiency. When cleaning, simply open the corresponding dust cup cover and sealing cover to clean them separately, without the need for tapping or shaking, improving the user experience.
