In this embodiment, the hanger 110 is a substantially U-shaped bent long plate-shaped structure, the outer surface 111 is the outer circumferential surface of the hanger 110, and the human body contact surface 112 is the inner circumferential surface of the hanger 110. The distance between the outer surface 111 and the human body contact surface 112 is the thickness of the hanger 110. The spacing between the outer surface 111 and the human body contact surface 112 may be equal everywhere, i.e., the thickness of the hanger 110 is uniform, which may improve the uniformity of the appearance of the hanger 110. The housing 130 may be rotatably connected to the outer surface 111 or may be rotatably connected to the human body contact surface 112, in this embodiment, the housing 130 is rotatably connected to the outer surface 111 as an example, and the specific structure of the housing 130 rotatably connected to the human body contact surface 112 may refer to the structure of the housing 130 rotatably connected to the outer surface 111.

The hanger 110 may be hung on the neck of a human body, the human body contact surface 112 is used to contact the skin of the neck of the human body, and the shape of the hanger 110 may be matched with the neck of the human body so that the hanger 110 may be stably hung on the neck of the human body. Of course, the neck-worn fan 100 may be hung on an arm of a human body for use, or directly placed on a table for use, or directly held by a hand for use, and the like, and the embodiment is not particularly limited.

The housing 130 has a substantially elongated flat structure, the housing 130 includes a connecting end 133 and a free end 134 opposite to each other along the length direction Y, the housing 130 is rotatably connected to the hanger 110 at the connecting end 133, and the housing 130 rotates around the connecting end 133.

The flow direction of the fluid in the air duct 131 is the same as the longitudinal direction of the housing 130, that is, the extending direction of the air duct 131 is the same as the longitudinal direction of the housing 130. The fan 140 may be disposed at the free end 134 of the housing 130, such that the fluid in the wind path 131 may flow from the free end 134 to the connection end 133 of the housing 130 and be blown out through the wind outlet 132.

In some embodiments, the fan 140 may also be disposed at approximately the middle of the wind tunnel 131, so that two streams of fluid with different flow directions can be generated in the wind tunnel 131, wherein one stream of fluid flows from the middle of the wind tunnel 131 to the connecting end 133 of the housing 130, and the other stream of fluid flows from the middle of the wind tunnel 131 to the free end 134 of the housing 130.

Referring to fig. 1 and 2, the hanger 110 may include an arc portion 113, a first extending portion 114 and a second extending portion 115, the first extending portion 114 and the second extending portion 115 are respectively connected to two ends of the arc portion 113, the air outlet assembly 120 may include two air outlet assemblies 120, and the two air outlet assemblies 120 are respectively connected to the first extending portion 114 and the second extending portion 115 to increase air outlet amount and air outlet coverage.

In this embodiment, the arc portion 113 is a substantially arc-shaped plate, the first extending portion 114 and the second extending portion 115 are substantially rectangular plates, and the arc portion 113, the first extending portion 114 and the second extending portion 115 may be integrally formed to form the outer surface 111 and the human body contact surface 112 of the hanger 110. When the hanger 110 is hung on the neck, the arc portion 113 is disposed around the neck of the human body, the first extending portion 114 and the second extending portion 115 are located near the cheek of the human body, and the free end 134 of the casing 130 can be rotated forward to a position near the cheek of the human body (see fig. 1), or rotated backward to a position near the back of the brain of the human body (see fig. 3), or rotated to any other position (see fig. 4), so that the air outlet coverage of the casing 130 is wide.

Referring to fig. 1 and 3, the housing 130 further has a first air inlet 1361 located at the free end 134, the first air inlet 1361 is located on a side surface of the housing 130 close to the hanger 110, when the housing 130 rotates to a position where the free end 134 is located at a same side as the arc portion 113, and the connecting end 133 is located at a same side as the first extending portion 114 and the second extending portion 115, the specific direction can be shown in fig. 3, at this time, the free end 134 of the housing 130 rotates to a position close to the back of the human brain, and the free end 134 can be located outside the range of the hanger 110, so that the first air inlet 1361 avoids the hanger 110, and the influence on the inlet air of the first air inlet 1361 is avoided.

When the free end 134 of the housing 130 is rotated forward to a position near the cheek of the person, the first and second extensions 114 and 115 may be fitted to the housing 130 to improve the mounting stability of the housing 130. The length of the casing 130 may be greater than the lengths of the first extending portion 114 and the second extending portion 115, so that when the casing 130 rotates to the same side of the free end 134 as the first extending portion 114 and the second extending portion 115, and the connecting end 133 is the same side as the arc-shaped portion 113, the free end 134 of the casing 130 may also be located outside the range of the hanger 110, so as to prevent the first extending portion 114 and the second extending portion 115 from blocking the inlet air of the first inlet opening 1361. Still referring to fig. 1 and 2, the hanger 110 has a first connecting portion 116, the housing 130 has a second connecting portion 150, and the first connecting portion 116 and the second connecting portion 150 cooperate to rotatably connect the housing 130 and the hanger 110 and position the housing 130, so that the housing 130 can be positioned at a position adjusted by a user.

For example, the first connection portion 116 is a mounting hole, the second connection portion 150 is a connection column, or the first connection portion 116 is a connection column, and the second connection portion 150 is a mounting hole, which can realize the rotational connection between the housing 130 and the hanger 110, and position the housing 130. When the first connection portion 116 is a mounting hole, the mounting hole penetrates the outer surface 111.

In some embodiments, one of the first connecting portion 116 and the second connecting portion 150 includes a mounting hole and a plurality of limiting grooves arranged along the circumferential direction of the mounting hole, and the other includes a connecting column and a resilient protrusion disposed on the outer edge of the connecting column, and the limiting grooves and the resilient protrusion are adapted to each other. For example, the first connecting portion 116 includes a mounting hole and a plurality of limiting grooves arranged along the circumference of the mounting hole, and the second connecting portion 150 includes a connecting column and an elastic protrusion disposed on the outer edge of the connecting column. Or, the first connecting portion 116 includes a connecting column and an elastic protrusion disposed on an outer edge of the connecting column, and the second connecting portion 150 includes a mounting hole and a plurality of limiting grooves arranged along a circumferential direction of the mounting hole.

Therefore, when the user rotates the housing 130, the elastic protrusion may slide out of one of the limiting grooves and slide into the other limiting groove to position the second connecting part 150, so that the housing 130 may be positioned at a position adjusted by the user.

Referring to fig. 1 and 5, the rotation axis of the fan wheel 140 may be perpendicular to the length direction of the housing 130, the air outlet 132 includes a first sub air outlet 1321 and a second sub air outlet 1322, the first sub air outlet 1321 and the second sub air outlet 1322 are respectively disposed on two sides of the housing 130 along the length direction Y, the first sub air outlet 1321 is at least partially located in the radial direction of the fan wheel 140, and the second sub air outlet 1322 is at least partially located in the radial direction of the fan wheel 140. With reference to the orientation shown in fig. 5, the first sub-outlet 1321 may be located on an upper side of the housing 130, and the second sub-outlet 1322 may be located on a lower side of the housing 130.
