[0005] By adopting the above technical solution, a dust bucket is arranged in the dust cup, a motor cover is arranged in the dust bucket, and the motor is arranged in the motor cover. In this way, the outside of the motor has three layers of sound insulation wall, which can greatly reduce the noise of the motor. During use, the entire vacuum cleaner is almost noiseless, achieving the purpose of noise reduction. In the present invention, dust enters the dust cup from the air inlet, enters the cyclone separator through the air inlet channel, and after separation by the cyclone separator, the dust falls into the fine ash bin from the air outlet channel.

[0006] The present invention is further configured as follows: the cyclone separator includes a separator shell connected to the dust bin and a mounting plate arranged on the top of the separator shell, a plurality of cyclone cones are arranged at the bottom of the mounting plate, an opening is arranged at the top of the cyclone cone, and an air guide plate is arranged at the opening.

[0007] By adopting the above technical solution, an opening is set at the top of the cyclone cone. When the wind reaches the cyclone cone from the air inlet channel, it enters the cyclone cone from the opening at the top of the cyclone cone, and then exits from the bottom of the cyclone cone. The wind guide plate has a wind guiding effect.

[0008] The present invention is further configured as follows: the mounting plate is provided with sleeve rods equal in number to the rotating cones, each cyclone cone is respectively sleeved on each sleeve rod, and multiple cyclone cones are arranged on the mounting plate in two circles, the number of cyclone cones in the outer circle is twice the number of cyclone cones in the inner circle, each cyclone cone in the inner circle is respectively connected with every two cyclone cones in the outer circle through a connecting plate to form a cyclone cover body with a triangular cross-section, the dust bin and the motor cover body are connected through a partition corresponding to the shape of the cyclone cover body, a fixing plate is provided between the bottom of the dust bin and the motor cover body, a mounting opening corresponding to the shape of the cyclone cover body is provided on the top of the partition, a mounting step for installing the cyclone cover body is provided at the mounting opening, and a dust outlet communicated with the mounting opening is provided on the fixing plate, and the dust outlet is communicated with the fine ash bin.

During the separation process, the dust falls into the fine dust bin through the air outlet channel, and the air is directly discharged through the air outlet on the top of the motor cover. Through this setting, the cyclone cone is not inside the dust bin, which can avoid the generation of static electricity, and the filter cotton is not inside the dust bin, which makes it easier to take out and replace.

[0014] The present invention is further configured as follows: an air outlet filter is arranged in the fine ash bin, and a plurality of small holes which are in communication with the motor cover are arranged on the top of the air outlet filter.

[0015] By adopting the above technical solution, after the wind is discharged through the motor cover, it enters the air outlet filter through the small hole, is filtered by the air outlet filter again, and then is discharged from the bottom of the fine ash bin to the outside of the dust collector.

[0017] By adopting the above technical solution, one end of the base bracket is installed on one side of the bottom of the dust cup, and the other end is buckled on the other side of the dust cup through a buckle, so as to support and fix the fine ash bin and prevent it from falling off. The air outlet filter is installed in the fine ash bin and is integrated with the fine ash bin. When the fine ash bin is taken out, the air outlet filter is taken out together, which is convenient for the replacement of the air outlet filter. At the same time, since the fine ash is recovered through a separate fine ash bin, there will not be much movement when dumping, and no dust will be generated.

[0018] The present invention is further configured as follows: the motor is perpendicular to the horizontal plane of the dust cup, and the central axis of the cyclone cone is parallel to the central axis of the motor.

[0019] By adopting the above technical solution, the motor is perpendicular to the horizontal plane of the dust cup, so that air inlet and outlet are smoother, and the central axis of the cyclone cone is parallel to the central axis of the motor, so that the cyclone separation is more thorough.

[0020] The present invention is further configured as follows: the axis of the motor is tangent to the direction of the air inlet, and the axes of the air inlet channel and the air outlet channel are parallel.

[0021] By adopting the above technical solution, the motor axis is tangent to the air inlet direction, so that a first-level cyclone can be formed, which is conducive to separation, and the air inlet channel is parallel to the air outlet channel axis, so that the air inlet channel and the air outlet channel are on the same object, making the overall structure small and light.

In the present invention, dust enters the dust cup 1 from the air inlet 11, enters the cyclone separator 2 through the air inlet channel 12, and after separation by the cyclone separator, the dust falls into the fine ash bin 6 from the air outlet channel 13.

[0029] The cyclone separator 2 includes a separator housing 21 connected to the dust barrel 3 and a mounting plate 22 arranged on the top of the separator housing 21. A plurality of cyclone cones 23 are arranged at the bottom of the mounting plate 22. An opening 24 is arranged at the top of the cyclone cone 23, and a wind guide plate 25 is arranged at the opening 24. The opening 24 is arranged at the top of the cyclone cone 23. When the wind reaches the cyclone cone 23 from the air inlet channel 12, it enters the cyclone cone 23 from the opening 24 at the top of the cyclone cone 23, and then the wind is discharged from the bottom of the cyclone cone 23.

Multiple cyclone cones 23 are arranged in two circles on the mounting plate 22, and the number of cyclone cones 23 in the outer circle is twice the number of cyclone cones 23 in the inner circle. Each cyclone cone 23 in the inner circle is respectively connected with every two cyclone cones 23 in the outer circle through a connecting plate to form a cyclone cover 27 with a triangular cross-section. The dust bucket 3 and the motor cover 5 are connected through a partition 31 corresponding to the shape of the cyclone cover 27. A fixing plate 32 is provided between the bottom of the dust bucket 3 and the motor cover 5.

The cyclone cover 27 is inserted into the mounting opening 33 on the partition to achieve connection with the dust bin 3. The dust passes through the air outlet 23 from the outlet at the bottom of the cyclone cone 23, and then falls into the fine ash bin 6 through the dust outlet 35.

[0031] The outer surface of the dust barrel 3 is provided with a filter 36. When dust enters the dust cup 1 from the air inlet 11, it is first filtered by the filter 36 and then enters the air inlet channel 12, thus achieving the first filtration.
