However, in the process of blowing air to the back of the human body, the air is easily blocked by the clothes, so that the air blowing effect is not good. Therefore, the present application proposes a neck hanging fan to improve the above-mentioned problems.

Referring to fig. 1, the present application provides a neck hanging fan 1, which includes a neck wearing frame 10 adapted to hang on a neck, an outer extension portion 20, and a first fan assembly 30. The outer extension 20 is connected to the neck wear frame 10 and the first fan assembly 30 is connected to the outer extension 20. In some embodiments, the neck wear frame 10 has an inner sidewall enclosing a neck wear space 11 for easy wearing.

In order to facilitate the neck wear rack 10 to be hung on the neck, when the neck hanging fan 1 provided by the present application is used, the neck can be inserted into the neck wear space 11, so as to hang the neck wear rack 10 on the neck and part of the shoulder. For example, referring to fig. 2, the neck wearing frame 10 includes two clamping portions 12 and a connecting portion 13, the two clamping portions 12 are respectively connected to two ends of the connecting portion 13, and a neck wearing space 11 is formed between the two clamping portions 12. The two clamping portions 12 can be bent or rotatably connected to two ends of the connecting portion 13, and the outer extension portion 20 is connected to the connecting portion 13.

In some embodiments, referring to fig. 3, the connecting portion 13 may be a bendable flexible member, and a gooseneck 141 may be further disposed in the connecting portion 13, for example, the gooseneck 141 may be a metal member that can be bent at will and oriented, so that the shape of the connecting portion 13 can be adjusted by the gooseneck 141 and the connecting portion 13 made of the flexible material can be supported. In other embodiments, other structures capable of supporting, such as iron wires, may also be provided, which is not limited herein. Thus, by bending the gooseneck 141, the connecting portion 13 can be deformed, facilitating adjustment of the distance between the two clamping portions 12.

Referring to fig. 2 again, in some embodiments, the neck wearing frame 10 further includes a rotating connecting member 14, the two clamping portions 12 are rotatably connected to the connecting portion 13 through a rotating connecting member 14, and two ends of the connecting portion 13 are provided with a silicone sleeve 15, the silicone sleeve 15 is sleeved outside the rotating connecting member 14 and is connected to the clamping portions 12. For example, the two clamping portions 12 may have a certain angle between two rotation axes rotating relative to the connecting portion 13, the rotating connection member 14 may be a universal joint (as shown in fig. 2), and in other embodiments, the rotating connection member 14 may have other structures, which are not limited herein. In this way, by rotating the two holding portions 12, the size of the neck wearing space 11 can be adjusted according to the body shape of the wearer, that is, the neck wearing space 11 can be suspended from the neck with an appropriate size.

In some embodiments, the neck fan 1 further comprises a silicone sleeve 15. The silica gel cover 15 can be located and rotate the connecting piece 14 outside by the cover, so can protect and rotate the connecting piece 14, and make the surface of connecting portion 13 and two clamping parts 12 form roughly continuous curved surface, avoided rotating on the connecting piece 14 because appear the gap, the emergence of the condition such as hair takes place to clip.

The outer extension portion 20 is used to connect the connecting portion 13 of the neck wearing frame 10 and the first fan assembly 30, so that when the neck wearing frame 10 is hung on the neck, the first fan assembly 30 can be directly disposed on the neck wearing frame 10 and is closer to the back. Illustratively, referring again to fig. 1, the extension portion 20 is connected to the connecting portion 13 and extends away from the neck wear frame 10. The extending portion 20 may be detachably connected to the connecting portion 13, or may be fixedly disposed on the connecting portion 13, which is not limited herein. In one embodiment, the extension portion 20 may be a bendable flexible member and integrally coupled to the connecting portion 13. Specifically, referring to fig. 4, the extension portion 20 is integrally formed with the connecting portion 13, and the extension portion 20 is connected to the lower side of the middle portion of the neck wear frame 10. In this way, the first fan assembly 30 connected to the outer extension portion 20 can be close to the back portion and spaced from the connection portion 13. Through being provided with extension portion 20, first fan assembly 30 can press close to the back and stretch out to the inboard of clothing and carry out the air-out, and radiating effect is better.

The first fan assembly 30 is used to blow air toward the back of the user. For example, referring to fig. 5, the first fan assembly 30 is provided with an air outlet 31, and the first fan assembly 30 is connected to an end of the outer extension portion 20 away from the neck wear frame 10. Since the neck wearing space 11 is used for hanging the neck wearing frame 10 on the neck, a certain distance is provided between the direction of the air outlet 31 and the neck wearing space 11, when the neck hanging fan 1 is hung on the neck from the back through the neck wearing space 11, the air outlet direction (y direction in the figure) of the air outlet 31 can be approximately parallel to the plane of the back of the human body, so that the first fan assembly 30 can blow to a larger area of the back.

In some embodiments, the first fan assembly 30 includes a housing 32 and at least one first fan wheel 33. Illustratively, a first accommodating cavity 321 is formed in the housing 32, the housing 32 is provided with an air inlet 322 and an air outlet 31 which are communicated with the first accommodating cavity 321, the air outlet 31 is arranged away from the outer extension portion 20, the outer extension portion 20 is connected to the housing 32, and at least one first impeller 33 is arranged in the first accommodating cavity 321. For example, the housing 32 may be integrally formed with the outer extension portion 20 and the connecting portion 13, the first accommodating cavity 321 is disposed inside the housing 32, and the air inlet 322 and the air outlet 31 are communicated with the accommodating cavity to form an air duct for air to flow. The first fan wheel 33 may be a centrifugal fan wheel, and when the centrifugal first fan wheel 33 drives the air flow, the air is sucked into the first fan wheel 33 along the axial direction (x direction in the figure) of the rotation of the first fan wheel 33 and is blown out from the direction (y direction in the figure) perpendicular to the axial direction of the first fan wheel 33. Therefore, the direction of the air inlet 322 is also substantially perpendicular to the direction of the air outlet 31, so that the air flowing in the first accommodation chamber 321 is less affected by turbulence generated due to the change of the air flowing direction, even if the power of the first impeller 33 is higher. Since the air outlet direction of the air outlet 31 is substantially parallel to the back of the human body, the air inlet 322 may be substantially perpendicular to the back.

Illustratively, in the present embodiment, the number of the at least one first impeller 33 is two, the two first impellers 33 are arranged in parallel and have opposite rotation directions, and a partition (not shown) is disposed in the first accommodating cavity 321 and located between the two first impellers 33 to separate the two first impellers 33 from each other.

The air outlet 31 may be disposed on one side of the housing 32 close to the back, but due to the air outlet 31 disposed perpendicular to the back, the problem that the back easily blocks air or closes the air inlet 322 when the back is close to the back plane, or the problem that the hair is easily drawn into the first impeller 33 from the air inlet 322 when the hair is too long, occurs. In some embodiments, therefore, the first fan assembly 30 further includes a baffle 34, the baffle 34 being configured to prevent the back plane from being proximate the intake vent 322. Illustratively, the baffle 34 is connected to the housing 32 and covers the air inlet 322, and has a gap with the outer wall of the housing 32, and the air inlet 322 is communicated with the gap. Thus, when the first fan assembly 30 is close to the air inlet 322, the baffle 34 contacts with the back before the housing 32, and the first fan assembly 30 can intake air through the gap between the housing 32 and the baffle 34, and simultaneously prevent hairs from being drawn into the first impeller 33. In other embodiments, the back portion can be prevented from approaching the air inlet 322 by arranging a protrusion or other forms on the housing 32, and the hair can be prevented from being rolled into the first impeller 33 by arranging a protection net at the air inlet 322, which is not described herein.

The air outlets 31 may also be disposed on one side of the casing 32 close to the back and the opposite side of the casing 32, and the arrangement of the air outlets 31 may reduce the resistance when air enters. Illustratively, the air inlet 322 includes an inner air inlet 3221 and an outer air inlet 3222, the inner air inlet 3221 is disposed on a side of the casing 32 facing the neck wear space 11, the outer air inlet 3222 is disposed on a side of the casing 32 opposite to the inner air inlet 3221, and accordingly, the baffle 34 may also include a first baffle 341 and a second baffle 342, the first baffle 341 is disposed near the inner air inlet 3221, and the second baffle 342 is disposed near the outer air inlet 3222. Thus, the amount of air taken into the first impeller 33 can be increased or the resistance to the air entering the casing 32 can be reduced. When the first fan assembly 30 extends into the clothes, the first baffle 341 can prevent the inner air inlet 3221 from being close to the back plane, and the second baffle 342 can also prevent the clothes from covering the outer air inlet 3222, so as to block the air inlet 3222 to cause the fan wheel to form negative pressure, thereby affecting the air inlet of the outer air inlet 3222.

Since the neck hanging fan 1 needs to be portable, the neck hanging fan 1 may be inconvenient to use if being worn in various places, such as if an external power supply is used. In some embodiments, referring to fig. 3 again, the neck hanging fan 1 further includes a battery 40 and a circuit board, and the battery 40 and the circuit board are disposed in the neck wearing frame 10 and electrically connected to the first fan assembly 30. Illustratively, a second receiving cavity 121 is formed in the neck wear frame 10, and the battery 40 and the PCB are disposed in the second receiving cavity 121. The battery 40 and the PCB can drive and control the start and stop of the neck hanging fan 1, so that the neck hanging fan is not limited by an external power supply. For example, referring to fig. 2 and 3 together, a second receiving cavity 121 may be formed in the clamping portion 12, and the battery 40 and the PCB may be disposed in the second receiving cavity 121, so as to fully utilize the space inside the neck wear frame 10. Meanwhile, since the battery 40 and the PCB have a certain weight, when the battery 40 and the PCB are disposed on the holding portion 12, the weight of the holding portion 12 can be approximately balanced with the weight of the connecting portion 13 and the first fan assembly 30, so that the neck hanging fan 1 can be hung on the neck more stably. In some embodiments, the neck fan 1 may further include a control unit (not shown) electrically connected to the battery 40 and the circuit board 50 for controlling the start/stop or the rotation speed of the first fan assembly 30. The control unit may be a button disposed on the neck wear frame 10, or a bluetooth module capable of communicating with an external device, such as a mobile phone, without limitation.

By only blowing air towards the back, the heat dissipation requirements of other body parts of the user may not be met in some use environments. In some embodiments, referring to fig. 1, fig. 2 and fig. 3, the neck hanging fan 1 further includes at least one second impeller 60, the second impeller 60 is disposed in the second accommodating cavity 121, and the holding portion 12 further has a second air inlet 122 and a second air outlet 123 communicated with the second accommodating cavity 121. The second air outlet 123 may be a plurality of small holes disposed on the neck wear rack 10 and communicated with the second accommodating cavity 121, or may be in other forms, which is not limited herein. The second impeller 60 can make the second outlet 123 face the face or other parts to meet the heat dissipation requirement of the user. For example, two second fan wheels 60 may be disposed in two non-connected second receiving cavities 121 formed in the two clamping portions 12, so that the weights of the two sides of the neck hanging fan 1 are substantially balanced, and the user is prevented from feeling inconvenient. Correspondingly, the number of the second air outlets 123 can be two, and the two second air outlets 123 are respectively disposed on the two clamping portions 12, and the two second air outlets 123 can be substantially opposite and disposed toward the face, so that air can be blown to two sides of the face of the user at the same time, and the use feeling of the user is improved.
