The airflow generator can generate negative pressure locally to enable the airflow generator to generate suction to the surrounding environment, and when the airflow generator is installed in the motor shell, negative pressure is generated inside the motor shell to generate suction to the external environment. When the airflow generator is embedded in the motor cover, external airflow is sucked in through the motor air combing opening and then is discharged to the outside from the motor air outlet. The movement path of the airflow in the motor shell is that the airflow enters from a motor air combing opening at the top of the motor shell and then flows towards the bottom of the motor shell, and when the airflow moves to the motor air outlet, the movement direction of the airflow is changed and the airflow is discharged outwards from the motor air outlet. Among the prior art, the reason that airflow generator produced the noise does, and the route of airflow at the inside motion of airflow generator is the straight line route, and the airflow gets into from airflow generator's one end, and the air flue is shorter relatively, and when the airflow flowed in the air flue, the airflow had the noise reflection in the air flue to offset some noise, consequently straight and shorter air flue is unfavorable for the noise and eliminates in the air flue, thereby produces great noise.

In addition to the above embodiments, as a further limited embodiment, the air flow generator is co-linear with the central axis of the dust separator, as shown in figure 6. The whole of the combination of the airflow generator and the dust and dirt separator is more compact, and the space occupied by the integral structure of the dust and dirt separator and the airflow generator is further reduced.

Specifically, as shown in fig. 5 and 6, the vacuum motor c1 can be regarded as a cylinder as a whole, the center of the dust separator has a cylindrical cavity, and the vacuum motor c1 is just embedded into the cylindrical cavity in the middle of the dust separator. As an alternative embodiment, the dust separator and the central axis of the vacuum motor c1 are parallel to each other. As another alternative, the dirt separator intersects a line on which the central axis of the vacuum motor c1 lies.

On the basis of the above embodiment, as a further limited embodiment, as shown in fig. 6 to 8, the dust-dirt separator includes: a motor housing c2 disposed in the main housing a, the airflow generator being disposed in the motor housing c 2; and the air guide cone c203 is arranged between the motor shell c2 and the main machine shell a. The motor housing c2 is used to form a cavity for embedding and installing the vacuum motor c1, and the air guiding cone c203 is arranged outside the motor housing c2 and distributed around the vacuum motor c 1.

Further, as shown in fig. 6, the outward facing surface of the motor base c3 is an arc surface, that is, the surface of the motor base c3 that is under the view angle of fig. 6 is an arc surface, and with reference to fig. 1-3, the whole body formed by the motor housing c2 and the motor base c3 is located inside the casing of the whole machine, and the airflow entering from below the dust separator flows to the smaller opening at the bottom of the wind cone c203 under the guiding action of the arc outer surface of the motor base c 3. The opening ring at the bottom of the air guide cone c203 is arranged around the edge of the arc surface of the motor base c3, so that the air flow can enter the air guide cone c203 more easily for further dust removal and separation.

In addition to the above-described embodiments, as a further limited embodiment, as shown in fig. 6 to 8, the cross-sectional area of the air guide cone c203 gradually increases along the flow direction of the airflow, and the air guide cone c203 includes: and the lateral air outlet c2031 is arranged on the side wall of the air guide cone c203 and is close to the top of the air guide cone c 203. In the process that the airflow rises from the bottom of the air guiding cone c203 along the inner wall of the air guiding cone c203, the airflow moves to a lateral air outlet c2031 formed on the side wall of the air guiding cone c203 and flows out from the lateral direction.

In the view of fig. 6, the left air guide cone c203 is inclined to the left away from the vacuum motor c1, so that when the air flow flows by adhering to the inner wall of the air guide cone c203, the distance from the central axis of the vacuum motor c1 increases more and more, and the component force capability of the air guide cone c203 on dust and impurities is further improved.

The motor air combing opening c201 is an opening formed in the top of the motor housing, the specific structure of the motor air combing opening c201 is not limited, and the motor air combing opening c201 is a circular opening structure penetrating through the top of the motor housing c2 in this embodiment.

Because the air guide cone c203 is arranged around the vacuum motor c1, the motor air combing opening c201 at the top of the vacuum motor c1 is surrounded by the air guide cone c203, and because the height of the motor air combing opening c201 is lower than that of the lateral air outlet c2031, a groove-shaped space surrounded by the air guide cone c203 is formed above the motor air combing opening c201, a first filter c7 can be further installed in the groove-shaped space, and the first filter c7 can further filter and purify the air flow before the air flow enters the vacuum motor c 1. And the vacuum motor c1 and the air guide cone c203 are originally parts arranged in the shell of the whole machine, and a new installation structure is formed among the parts, so that the assembly among the parts is more compact, and the volume of the main machine part of the handheld dust collector is further reduced. As an alternative embodiment, the height of the motor air delivery opening is the same as the height of the lateral air outlet c 2031. As another alternative, the height of the motor air delivery opening is higher than the height of the lateral air outlet c 2031.

Furthermore, the lateral air guiding sheets do not directly point to the motor air combing opening c201, so that the air flow flowing out of the lateral air outlet c2031 is uniformly mixed before entering the motor air combing opening c201, and the air flow entering the motor air combing opening c201 is more uniform.

In this embodiment, a position of the motor housing c2 corresponding to the motor air combing opening c201 is provided with an air combing grid, and the air current flowing out of the air guiding cone c203 and guided by the lateral air guiding sheet flows into the motor air combing opening c201 more uniformly after passing through the air combing grid.

The air flow in the vacuum motor c1 flows in a direction from the top of the vacuum motor c1 to the bottom, so that the motor outlet c205 is located on the side wall of the vacuum motor c1 and is far away from the motor outlet c205 to form a motor outlet channel c204, and when the air flow moves downward in the vacuum motor c1, the air flow turns to the motor outlet c205, that is, the flow path of the air flow is further bent, so that the noise reflection is further increased, and the noise is reduced.

In addition to the above embodiments, as a further limited embodiment, as shown in fig. 6, the height of the airflow flowing in the motor air outlet channel c204 is gradually increased. The flow path of the airflow after flowing out of the air outlet is bent towards the top of the vacuum motor c 1. Further increase noise reflection, reduce the noise.

The height of the motor air outlet c2022 is not lower than that of the motor air combing opening c201, which means that after the air flow flows out from the lower half part of the vacuum motor c1, the air flow bends towards the top of the vacuum motor c1, not only the noise reflection is increased, the noise is reduced, but also the length of the whole air duct is lengthened, the energy of the noise is dissipated in the air duct, the length of the whole air duct is lengthened, the dissipation amount of the noise energy is increased, and therefore the integral working noise of the handheld dust collector is reduced. As an alternative embodiment, the height of the motor air outlet c2022 is lower than the height of the motor air combing port c 201.

On one hand, the motor exhaust channel c202 can further extend the whole air duct, and on the other hand, a new turning angle can be formed between the motor exhaust channel c202 and the motor exhaust channel c202, so that the flow path of the air flow is further turned, and the noise energy is further dissipated.

In this embodiment, the motor exhaust duct is horizontally arranged and intersected with the motor air outlet channel c204 which is obliquely arranged, and the air flow turns when passing through the connecting part between the motor exhaust duct and the motor air outlet channel c 204.

As shown in fig. 3 and 6, in addition to the above-described embodiments, as a further limited embodiment, the motor exhaust duct c202 includes: and the air exhaust sponge c2021 is arranged at the upstream of the motor air exhaust port c 2022. The exhaust sponge c2021 can further filter the air before it flows out of the motor exhaust c 2022.
