Detailed Description

For a better understanding of the present invention, the following further description is made with reference to the accompanying drawings.

As shown in fig. 1-4, which are schematic structural views of the handheld vacuum cleaner of the present invention, the handheld vacuum cleaner includes a cleaner body 10, a dust collecting chamber 110, an air guiding device 150, a filtering device, a dust suction opening 130, and an annular handle 20; the dust suction port 130, the air guide device 150, the dust collection chamber 110 and the cleaner body 10 are sequentially and fixedly connected, the air guide device 150 enables air and dust mixture to rotate at a high speed in the dust collection chamber 110, and dust and sundries are separated from air by utilizing the centrifugal force principle; the filter is provided inside the dust collecting chamber 110 for filtering dust entering the cleaner body 10. Annular handle 20 and dust catcher main part 10 fixed connection, dust catcher main part 10 includes dust catcher motor 120, battery 30, battery terminal 310, and the technical personnel in this field only need simply will dust catcher motor 120, battery terminal 310 connect gradually with battery 30, make battery 30 supply power to dust catcher motor 120, and this connected mode can reduce handheld dust catcher's volume, and because dust catcher motor 120 and battery 30 set up the inside at dust catcher main part 10 for the focus of handheld dust catcher is concentrated at annular handle center, makes the operator when the dust absorption operation, can adjust the position of holding according to the circumstances, changes the relative position of fuselage focus and wrist, thereby solves the tired problem of wrist. Those skilled in the art only need to simply set the filtering device to be connected to the air inlet of the cleaner motor 120, and the air outlet of the cleaner motor 120 is set at both sides of the cleaner body 10. Through adopting the air-out of straight line air inlet side with the dust catcher motor, reduce operating personnel and inhale the discarded harm of discharge when improving the smooth and easy degree of air inlet.

The outer contour of the annular handle 20 is circular, the distance between the annular handle 20 and the dust collector main body 10 is enough for a person to hold by one hand or two hands and has redundancy, the angle of the hand is wider, and the wrist can be adjusted by more angles relative to the dust collector main body 10 by adopting two modes of holding by one hand and two hands, so that the fatigue degree of the wrist is reduced. And the ring-shaped handle 20 has an anti-slip texture structure to increase friction force when being held, thereby preventing accidental release of hands.

The dust suction port 130, the dust collection chamber 110 and the filtering device are positioned on the same axis, so that the air inlet efficiency is higher, and the energy loss is small.

The handheld dust collector is also provided with an illuminating device which is arranged at the dust suction port and used for illuminating when the handheld dust collector is used for treating dust at dark corners and other places such as under seats.
