Detailed Description

In order to facilitate understanding of the present invention, the present invention will be described more fully hereinafter with reference to the accompanying drawings. One or more embodiments of the present invention are illustrated in the accompanying drawings to provide a more accurate and thorough understanding of the disclosed embodiments. It should be understood, however, that the present invention may be embodied in many different forms and is not limited to the embodiments described below.

As shown in fig. 1-3, the utility model provides a multifunctional neck wearing fan capable of being worn around human neck, which comprises a support 10, a fan 16 and an acoustic control unit 18, wherein the fan is arranged in the support 10.

In this embodiment, the stent 10 includes a flexible connecting section 12 and two shells 14 respectively connected to two ends of the flexible connecting section 12. The two housings 14 have the same structure and are symmetrical to each other, and one fan 16 is disposed in each housing 14. Preferably, the fan 16 is located at an end of the housing 14 remote from the flexible connecting section 12. In this embodiment, the flexible connecting section 12 and the two shells 14 are formed separately and then connected together to form the stent 10. It should be understood that in some embodiments, the two shells 14 may be directly connected to form a bracket, thereby omitting the flexible connecting section 12, or the two shells 14 may be connected to form a bracket by a rigid connecting section which is not bendable, or the flexible connecting section 12 and the two shells 14 of the bracket may be of an integral non-detachable structure.

Each of the housings 14 has a hollow structure with a partition 20 and a partition 22 provided therein. The

partitions

20 and 22 each extend along the length of the housing 14. The partition 20 divides the inner space of the housing 14 into a first cavity 24 and a second cavity 26 that are not communicated with each other, and the first cavity 24 and the second cavity 26 are arranged side by side in the left-right direction of the figure. Wherein, the first cavity 24 is located at the outer side of the casing 14, that is, the side of the casing 14 facing away from the neck of the human body; the second cavity 24 is located inside the housing 14, i.e. on the side of the housing 14 facing the neck of the person. The partition 22 is disposed in the second cavity 26, and further divides the second cavity 26 into an air duct 28 and a second sub-cavity 30 which are not communicated with each other. The air duct 28 and the second sub-chamber 30 are arranged side by side in the up-down direction of the figure, wherein the air duct 28 is located above the second sub-chamber 30. The first cavity 24, the air duct 28 and the second sub-cavity 30 are all not communicated with each other, the fan 16 is disposed in the air duct 28 and located at a terminal of the air duct 28 far from the flexible connecting section 12, and the air flow generated by the operation of the fan can only flow along the air duct 28 until the air flow is discharged out of the housing 14.

An air inlet 32 is arranged on the casing 14 corresponding to the fan 16, and an air outlet 34 is arranged outside the air duct 28. In this embodiment, the fan 16 is a centrifugal fan, the air inlet 32 is formed at the inner side and/or the outer side of the casing 14, and the air outlet 34 is formed at the upper side of the casing 14. When the fan 16 operates, external air is sucked from the air inlet 32, and the sucked air is accelerated and pressurized by the fan 16, flows along the air duct 28, and is finally blown out from the air outlet 34. Due to the double separation function of the partition 20 and the partition 22 on the inner space of the shell 14, the cross section area of the air duct 28 can be effectively reduced, the air flow generated by the fan 16 is more concentrated after entering the air duct 28, and the air speed blown out from the air outlet 34 is higher, so that the user can enjoy cool air, and the use experience of the user is improved.
