The battery 4 is used for supplying power to the circuit board 3 and the driving mechanism 2, and the display screen 6 can display related information, such as the electric quantity of the battery 4, the current gear position of the driving mechanism 2 and the like. The switch key 5 is used for controlling the driving mechanism 2 to work or not work.

It should be emphasized that the battery 4 and the circuit board 3 are respectively disposed in the two housings 1, and the connecting member 101 is hollow for connecting the circuit board 3 and the battery 4.

The shell 1 comprises a left half shell 11, a right half shell 12, a top shell 13 and a bottom shell 14, wherein the left half shell 11 and the right half shell 12 are detachably clamped, the top shell 13 is inserted into one ends of the left half shell 11 and the right half shell 12, and the bottom shell 14 is detachably clamped to the other ends of the left half shell 11 and the right half shell 12.

The left half shell 11 and the right half shell 12 are hollow, and after being connected, form a containing cavity 111 together, and the driving mechanism 2, the circuit board 3 and the battery 4 are all located in the containing cavity 111.

The left half shell 11 is provided with a first mounting opening 112 and a second mounting opening 113, the first mounting opening 112 is used for mounting the switch key 5, and the second mounting opening 113 is used for mounting the display screen 6.

Opposite ends of the left half shell 11 after being connected to the right half shell 12 are a first end 114 and a second end 115, respectively. It is apparent that top shell 13 is disposed at second end 115 and bottom shell 14 is disposed at first end 114.

The top shell 13 is provided with a clamping groove 131, and the clamping groove 131 is used for being matched with a clamping flange 1011 of the connecting piece 101 in a clamping way.

The bottom shell 14 is provided with a clamping hole 141, and the clamping hole 141 is used for being buckled with the left half shell 11 and the right half shell 12.

The bottom case 14 is further provided with a plurality of air inlets 142, and the plurality of air inlets 142 are uniformly arranged along the circumferential side of the housing 1, so that external air can be simultaneously introduced from the plurality of air inlets 142, and sufficient air flow can be provided.

Referring to fig. 1 and 2, the casing 1 is between the first end 114 and the second end 115, and it may also be understood that three air outlets, that is, a first air outlet 116, a second air outlet 117, and a third air outlet 118, are provided at a side portion of the casing 1, where the first air outlet 116 is opposite to the display screen 6, and the second air outlet 117 and the third air outlet 118 are opposite to each other in another direction of the casing 1. The air outlet has all been seted up to casing 1 in three orientation, and accommodation chamber 111 intercommunication air intake 142 and all air outlets, under actuating mechanism 2's drive, outside air gets into accommodation chamber 111 through air intake 142, blows out through a plurality of air outlets by accommodation chamber 111 simultaneously again, and the scope of blowing is big, and user's experience of blowing is felt well.

The casing 1 is provided with the wind-guiding slope 119 in the position of first air outlet 116, second air outlet 117 and third air outlet 118, in the direction of first end 114 to second end 115, the distance of wind-guiding slope 119 and casing 1 surface is degressive for the air current that holds chamber 111 through guiding slope 119 can blow off more smoothly, and the blowing that the user felt can be bigger, and it is more comfortable to blow, and the radiating effect is better.

It will be appreciated that in other embodiments, the air guiding ramp 119 may be provided only at one or both of the air outlets, or none of the air guiding ramp 119 may be provided. The shape of the air guide slope 119 is not limited, and may be a planar shape or a cambered shape, and thus, the air guide slope can perform a good air guide function.

The second air outlet 117 and the third air outlet 118 have the same length, and the length of the first air outlet 116 is greater than the length of the second air outlet 117 and also greater than the length of the third air outlet 118. The first air outlets 116 formed in the two shells 1 are arranged to face each other, which means that the two first air outlets 116 are arranged on the inner side of the neck fan 100, and the length of the first air outlets 116 is larger. In the use process of a user, the inner side of the neck hanging fan 100 faces the head of the user, and the wind blown out of the two first air outlets 116 can simultaneously blow and radiate heat to the head of the user, so that the heat radiation effect is better.

It should be emphasized that, two opposite sides of the two housings 1 may be understood that the outside of the neck hanging fan 100 is not provided with an air outlet, and the head and the neck of the user are both located at the inner side of the neck hanging fan 100 during the use of the neck hanging fan 100, and the outside of the neck hanging fan 100 is air. If the air outlet is formed on the outer side of the neck hanging fan 100, the manufacturing cost is increased, and a part of air flow in the accommodating cavity 111 is blown out from the outer side of the neck hanging fan 100 to cause waste of the air flow, so that the air blown out from the inner side of the neck hanging fan 100 is not large enough, which is not beneficial to improving the heat dissipation efficiency.

The first air outlet 116, the second air outlet 117 and the third air outlet 118 on the same housing 1 are located at the same height of the housing 1, however, in other embodiments, the first air outlet 116, the second air outlet 117 and the third air outlet 118 may not be located at the same height, and may be located vertically offset on the side of the housing 1, which is not limited herein.

The driving mechanism 2 comprises a driving motor 21 and a fan wheel 22 which are connected, and the fan wheel 22 is arranged close to the air inlet 142. The user can manually press the switch key 5 to control the driving motor 21 to drive the fan wheel 22 to rotate, and the fan wheel 22 drives air outside the shell 1 to enter the accommodating cavity 111 through the air inlet 142, and then the air flow is blown out from the accommodating cavity 111 through a plurality of air outlets. In this process, the flowing air flow can also take out the heat generated by the driving motor 21, which is beneficial to heat dissipation of the driving motor 21.

In summary, the multiple air outlets are arranged on the shell 1, and the directions of the air outlets are different, so that a large blowing range can be formed when the air outlets blow simultaneously, large-area heat dissipation can be realized for users, and the heat dissipation experience of the users is good.

The number of the air outlets of each housing 1 is described as three, but in other embodiments, the number of the air outlets may be four or more, which is not limited herein.

The technical features of the above embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.

The foregoing examples illustrate only a few embodiments of the utility model, which are described in detail and are not to be construed as limiting the scope of the utility model. It should be noted that modifications, substitutions and improvements can be made by those skilled in the art without departing from the spirit of the utility model, and are intended to be within the scope of the utility model. Accordingly, the protection scope of the present utility model is subject to the claims.
