In this embodiment, the air outlet 42 may also be a third grill 42, the second air outlet 6212 of the adjusting member 621 is formed on a fourth grill matching with the third grill, when the adjusting member 621 is moved, the air inlet area between the first grill 51 and the second grill is increased, the air inlet area between the third grill 42 and the fourth grill is decreased, otherwise, the air inlet area between the first grill 51 and the second grill is decreased, the air inlet area between the third grill 42 and the fourth grill is increased, so as to adjust the air volume entering the air outlet duct 5 and entering the air outlet 42, the air entering the air outlet duct 5 is blown out through the air outlet 52, and thus when the handheld vacuum cleaner 100 cleans the sundries and dust left in a small corner, the air flow blown out from the air outlet 52 blows up the dust and sundries in the gap, and then sucks the handheld vacuum cleaner 100 under the air flow of the fluid channel 4, improve clean efficiency, simultaneously, in order to avoid the air current velocity of flow that the mouth 52 of blowing blew out too big, dust can fly out long distance, and can't get into from fluid passage 4's suction port 41, cause the decline of clean efficiency and influence the operating comfort of operation, the air current velocity of flow that blows out needs to be reduced this moment, or, in order to avoid the air current velocity of flow that the mouth 52 of blowing blew out undersize, dust fly out the distance not enough, and can't get into from fluid passage 4's suction port 41, cause the decline of clean efficiency, the air current velocity of flow blows out needs to increase this moment, in this embodiment, only need to remove regulating part 621 can.

In order to facilitate the movement of the adjusting member 621, the adjusting mechanism 62 further includes a push button 622 connected to the adjusting member 621, and at least a portion of the push button 622 protrudes out of the housing 1 for convenient operation. Specifically, the housing 1 is provided with an opening 11, and at least a part of the push button 622 protrudes out of the housing 1 through the opening 11; the size of the opening 11 is larger than that of the push button 622, the opening 11 has a first end and a second end, the push button 622 moves in the first end and the second end to overlap or partially or completely misalign the first air inlet hole 511 and the second air inlet hole 6211 and overlap or partially or completely misalign the first air outlet hole 421 and the second air outlet hole 6212, and the first end and the second end of the opening 11 define the moving range of the push button. In this embodiment, the push button 622 and the adjusting member 621 are integrally formed, but not limited thereto, and the push button and the adjusting member 621 may be separately formed.

In other embodiments, in order to improve the heat dissipation efficiency of the battery pack, the adjustment cavity 61 is further provided with an outlet (not shown) which is communicated with a cooling channel for cooling the battery pack, so that the air flow flows through the cooling channel to cool the battery pack. Or at least part of the air outlet pipeline 5 flows through the battery pack, namely the air outlet pipeline 5 can firstly lead to the handle 7 and then surround the battery pack for one or more circles and then lead to the first connecting piece 8. Furthermore, at least part of the air outlet duct 5 can also flow outside the air flow generator 2 in order to cool the electric motor 22. The specific arrangement of the air outlet pipeline 5 can be set according to actual needs, and is not particularly limited herein.

It should be noted that the handle 7 is provided with a switch for turning on or off the handheld vacuum cleaner 100, the switch is of a conventional structure, and the switch controls the handheld vacuum cleaner 100 to work in the prior art, which is not described herein again.

The airflow direction in this embodiment is: the airflow generator 2 is started, external dust and air enter the dust and air separating part 32 of the dust and air separator 3 from the suction port 41 of the fluid passage 4 through the through hole 341 under the action of the airflow generator 2, and the dust and the dirt in the airflow are separated from the air under the action of the dust and air separator 3, the dust and the dirt come out from the dust removal port 321 and are deposited in the dust cup 36 under the action of gravity, the separated airflow enters the air inlet HEPA 26 along the conveying passage 25, the airflow is separated and filtered again to become clean air and enters the airflow generator 2, then the clean air flows out from the air outlet 21 of the airflow generator 2 and enters the adjusting cavity 61, part of the clean air enters the air outlet pipeline 5 and is blown out of the shell 1 under the action of the adjusting mechanism 62, and the rest of the clean air flows out of the shell 1 from the air outlet 42.

In conclusion, the handheld dust collector that this application provided, it is through being provided with the air-out pipeline that is used for blowing, realizes that handheld dust collector can breathe in simultaneously and blow, and handheld dust collector still has the bearing structure who prescribes a limit to the air-out pipeline to this makes handheld dust collector's rationally distributed, increases handheld dust collector's clean efficiency and application range.

The above description is only for the purpose of illustrating embodiments of the present invention and is not intended to limit the scope of the present invention, and all modifications, equivalents, and equivalent structures or equivalent processes that can be used directly or indirectly in other related fields of technology shall be encompassed by the present invention.
