The dust collecting assembly is used to collect solid dust and other garbage separated from the dust and gas, and includes a first dust collector 132 surrounded by a second housing 114.

The second housing 114 is substantially in the shape of a hollow cylinder with an open end. The housing 11 further includes a cover 115 disposed on the second housing 114, and the cover 115 is used to open or close the second housing 114. The side wall of the second housing 114 is also provided with a button 1151 for controlling the opening or closing of the second housing 114. Pressing the button 1151 can remove the cover 115 from the second housing 114. When using a hand-held vacuum cleaner, install the cover 115 so that the second housing 114 is a closed space with a cup bottom to form the first dust collector 132, and the dust entering the second housing 114 from the first air inlet 111 surrounds the cyclone The dust separated by the separating device 131 will fall and be contained in the first dust collector 132. When there is too much dust in the first dust collector 132, the cover 115 can be removed by pressing the button 1151 to clean up the dust. The connection mode of the button 1151 with the second housing 114 and the cover 115 is in the prior art, and will not be repeated here.

Referring to FIG. 5, the upper end of the secondary cyclone 1312 is provided with an air outlet 1314 that is used to enter the separated dust gas into the driving mechanism 12.

The main body 1 is also provided with a negative pressure component (not shown) capable of generating negative pressure. The negative pressure component is connected to the driving mechanism 12, and the driving mechanism 12 is activated to drive the negative pressure component to start and then form a negative pressure so that the external air flow can be freely After the first air inlet 111 enters, the first air outlet 112 flows to the outside of the casing 11. Dust gas enters the second housing 114 from the first air inlet 111, and can undergo a cyclone separation between the first-stage cyclone 1311 and the second housing 114 under the action of vacuum negative pressure, and then enters the first-stage cyclone separation Between the separator 1311 and the secondary cyclone 1312. At this time, the coarse ash (that is, garbage with larger particles) in the dust gas can be separated preliminarily by centrifugation. The coarse ash falls into the first dust collector 132, and then the preliminarily separated dust gas enters the second dust collector. In the stage cyclone 1312, the secondary cyclone separation is carried out in the second stage cyclone 1312. At this time, under the action of the centrifugal force, the finer dust in the dust gas can be separated, and the finer dust falls into the second dust collector 133, and finally the dust gas enters the driving mechanism 12 from the air outlet 1314. Therefore, the dust and gas can be separated multiple times by the cyclone separation device 131, which effectively improves the separation effect. Among them, the negative pressure component is a conventional structure such as a fan, which will not be repeated here. In other embodiments, the cyclone separation device 131 may be a multi-stage cyclone structure, and is not limited to a two-stage cyclone structure.
