A circular connecting plate 9 is arranged at the end of the cyclone cone 5, a snap ring 10 is arranged at the outer edge of the circular connecting plate 9. A snap groove 11 is arranged on the snap ring 10. A rubber ring gasket 12 is arranged on the circular connecting plate 9. A positioning hole 13 and a positioning protrusion 14 are arranged on the circular connecting plate 9. A dust suction sleeve 15 is arranged at the end of the cyclone cone 5. A partition plate 16 is arranged inside the dust cup housing 1. The upper end of the wind guide plate 8 is in contact with the circular connecting plate 9. The dust cup housing 1 is provided with a cup cover 2, which is convenient for users to open and close, and is convenient for cleaning and maintenance.

[0032] The dust cup L-shaped buckle 3 is arranged at the upper end of the dust cup housing 1, making the connection between the dust cup of the vacuum cleaner and the vacuum cleaner main body more stable and reliable. The swirl fan blade 501 is arranged on the outer surface of the cyclone cone 5, which can generate a strong centrifugal force to separate dust and impurities, improving the dust suction efficiency.

[0033] The end of the cyclone cone 5 is provided with a dust suction port 6, which is convenient for sucking in dust and impurities. The cyclone cone 5 is provided with a through hole 502, and a filter screen 7 is provided on the through hole 502, which can effectively filter tiny particles in the air and ensure the air quality. The upper part of the cyclone cone 5 is provided with an air guide plate 8, which can guide the direction of airflow and improve the dust suction effect. The cup cover 2 is provided with a cup cover lock 201, and a lock U-shaped seat 2011 is movably provided on the cup cover lock 201, so that the connection between the cup cover 2 and the dust cup shell 1 is tighter to prevent dust leakage.

[0034] The cyclone fan blades 501 extend outward to the dust cup housing 1 to open an air outlet 4, and a U-shaped groove 401 is provided at the outer edge of the air outlet 4, which is conducive to air circulation and improves the dust collection effect. A circular connecting plate 9 is provided at the end of the cyclone cone 5, and a buckle 10 is provided on the outer edge of the circular connecting plate 9 for easy connection with other components.

[0035] The buckle ring 10 is provided with a buckle groove 11 for easy installation and disassembly. The circular connecting plate 9 is provided with a rubber ring gasket 12, which can play a buffering role and reduce noise. The circular connecting plate 9 is provided with a positioning hole 13 and a positioning protrusion 14, which is convenient for alignment with other components. A dust suction cover 15 is provided at the end of the cyclone cone 5 to protect the cyclone cone 5 from damage. An isolation plate 16 is provided inside the dust cup housing 1 to isolate dust and impurities inside the dust cup to avoid secondary pollution. The upper end of the air guide plate 8 is in contact with the circular connecting plate 9, which can improve the stability of the airflow and improve the dust collection effect.

[0036] During the use of the utility model, when the vacuum cleaner starts to work, the motor drives the cyclone blades 501 to rotate at high speed. The rotation of the cyclone blades 501 generates a strong centrifugal force, forming an airflow, and sucking air containing dust and impurities from the dust suction port 6. The sucked airflow enters the cyclone cone 5, where the centrifugal force generated by the cyclone blades 501 is used to separate dust and impurities from the air. Due to the effect of gravity, these dust and impurities will slide down along the wall of the cyclone cone 5 and fall into the bottom of the dust cup housing 1.

[0037] The air after cyclone separation will pass through the through hole 502 on the cyclone cone 5, and further filter out smaller particles through the filter 7. The air guide plate 8 is located on the upper part of the cyclone cone 5, guiding the filtered clean air to the air outlet 4 of the dust cup housing 1, and releasing the clean air back into the environment. The clean air is discharged through the air outlet 4 of the dust cup housing 1. In this process, the U-shaped groove 401 helps to reduce turbulence and ensure smooth airflow.

[0038] As the dust accumulates inside the dust cup, the user can open the cup lid 2 by operating the cup lid lock 201 and the U-shaped seat of the lock 2011, and then pour out the dust in the dust cup. The end of the cyclone cone 5 is fixed to the buckle 10 through the circular connecting plate 9, ensuring the stability of the cyclone cone 5 inside the dust cup housing 1. At the same time, the design of the buckle groove 11, the positioning hole 13 and the positioning protrusion 14 makes the cyclone cone 5 easy to install and disassemble. A rubber ring gasket 12 is installed at the contact part between the cyclone cone 5 and the dust cup housing 1, which plays a role in shock absorption and noise reduction. The partition plate 16 inside the dust cup can prevent the separated dust from being sucked into the air flow again, avoiding secondary pollution.

[0039] The above embodiments are only used to illustrate the present invention and do not limit the technical solutions described in the present invention. Although this specification has described the present invention in detail with reference to the above respective embodiments, the present invention is not limited to the above specific implementation manners. Therefore, any modification or equivalent replacement to the present invention; and all technical solutions and their improvements that do not depart from the spirit and scope of the invention are covered by the scope of the claims of the present invention.
