[0027] See also Figures 1-10 The handheld vacuum cleaner with a blowing function comprises a body 1, an air outlet duct is provided on the body 1, an air outlet 3 is provided on the side of the body 1, and an air outlet 4 is provided at the end of the body 1. The air outlet 3 and the air outlet 4 are respectively opened and closed. When the air outlet 3 and / or the air outlet 4 are opened, the air outlet duct is connected to the outside through the air outlet 3 and / or the air outlet 4; when the handheld vacuum cleaner of this embodiment is used, the air outlet 3 is opened and the air outlet 4 is closed, so that air is discharged from the side of the body 1. This state is normal suction. In the dust collection state, the air blowing port 4 is opened and the air outlet 3 is closed, so that air is discharged from the rear end of the body 1. This state is a newly added use state, which is used to blow air and dust to special corners (such as wall corners). This state can be called the dust collection state, which realizes dust collection before dust collection (the normal use state during dust collection). In addition, the design of the air blowing port 4 allows the handheld vacuum cleaner to be taken outdoors for use, such as being used as a blower during barbecue, and blowing air to the charcoal fire through the air blowing port 4 to make the charcoal fire more vigorous.

[0028] A first cover body 5 is rotatably provided on the air outlet 3, and the first cover body 5 is provided with a through hole 6 corresponding to the air outlet 3, and an air outlet 7 connected to the outside world. The through hole 6 is aligned with or not aligned with the air outlet 3 through the rotation of the first cover body 5. When the through hole 6 is aligned with the air outlet 3, the air outlet 3 is opened, and the air outlet 3 is connected to the air outlet 7 through the through hole 6. When the through hole 6 is not aligned with the air outlet 3, the air outlet 3 is closed. The through hole 6 is provided on the side of the first cover body 5, and the air outlet holes 7 are distributed around the first cover body 5.

[0029] A plurality of rotating buckles 8 are provided in a ring shape on the first cover body 5 , and a plurality of buckle holes 9 are provided in a ring shape on the body 1 corresponding to the positions of the air outlet 3 .
