Claims

1. A hand-held fan, comprising a head portion and a hand-held portion, a fan is arranged in the head portion, a power supply unit is arranged in the hand-held portion, the power supply unit is electrically connected with the fan, characterized in that: The fan is also provided with an air passage in the air outlet direction. The air passage extends along the air outlet direction of the fan, making the head a cylindrical structure. A support arm is fixedly provided at the end of the hand-held part near the head. The end of the support arm away from the hand-held part is pivotally connected to one side of the outer circular surface of the head. The rotation axis of the pivot is perpendicular to the plane formed by the axis of the head and the axis of the hand-held part.

2. A hand fan as defined in claim 1, wherein: The head includes an outer shell and an inner shell. The inner shell has the fan, a first air guide channel and a second air guide channel arranged sequentially along the axial direction. The first air guide channel is snapped into a position near the air outlet of the fan. The first air guide channel and the second air guide channel are snapped into each other along the axial direction. Their inner walls together form an air passage for controlling wind pressure and wind speed.

3. A hand fan as defined in claim 2, wherein: The inner diameter of the second air guide channel is larger than the inner diameter of the fan outlet. The inner surface of the first air guide channel is conical and its inner diameter gradually transitions from the inner diameter of the fan outlet to the inner diameter of the second air guide channel. The second air guide channel is provided with a radially arranged array of partitions.

4. A handheld fan according to claim 3, characterized in that: The end of the second air guide channel closest to the first air guide channel is the air inlet, and the end of the second air guide channel furthest from the first air guide channel is the air outlet. The inner diameter of the second air guide channel gradually decreases from the air inlet to the middle section, and gradually increases from the middle section to the air outlet.

5. A hand fan as defined in claim 2, wherein: The inner shell includes a first inner shell located on the inner side and a second inner shell sleeved on the outer side of the first inner shell. The outer surface of the first inner shell has a plurality of arrayed protrusions, which create a gap between the first inner shell and the second inner shell.

6. A hand fan according to claim 5, wherein: The axial length of the second inner shell is greater than that of the first inner shell. The air outlet ends of the second inner shell and the first inner shell are aligned along the air outlet direction. The portion of the second inner shell that extends beyond the first inner shell is a hollow portion. The outer shell is provided with a grid portion on its side that is directly opposite the hollow portion. The grid portion forms a lateral air inlet.

7. A hand fan according to claim 6, wherein: The outer casing has several through holes at one end axially close to the fan, and the through holes form an axial air inlet.

8. A hand fan according to any one of claims 1-7, wherein: The support arm includes a vertical portion for hinged to the head, a horizontal portion for fixed to the hand-held portion, and an inclined portion connecting the vertical portion and the horizontal portion.

9. A hand fan according to claim 8, wherein: The vertical section, from near the head to away from the head, includes a first connecting body, a locking member, a second connecting body, and a vertical support section in sequence. The first connecting body is fixedly disposed on the outer circumferential surface of the head. The second connecting body has a slot with an opening facing the first connecting body, and a protrusion is provided on the inner circumferential wall of the slot. The locking member is disposed between the first connecting body and the second connecting body. The end of the locking member near the protrusion is an expanded diameter end that protrudes radially outward. The locking member can axially limit the second connecting body through the expanded diameter end and the protrusion. A locking screw passes through the first connecting body, the locking member, and the second connecting body. The second connecting body and the vertical support section are fixedly connected by a fixing screw.

10. A hand fan as defined in claim 9, wherein: The second connecting body, the horizontal part, and the inclined part are formed by the combination of stacked inner and outer support arms.
