Description

Technical Field

[0001] This utility model relates to the field of neck fan technology, and in particular to a neck fan that is easy to wear. Background Technology

[0002] A Chinese patent with publication number CN211692897U discloses a neck fan for wearing around a user's neck. It includes a main body and a fan disposed within the main body. The main body includes a support frame, which includes an inner wall near the user's neck and an outer wall away from the user's neck. An air duct is provided within the support frame. The inner wall includes a central region and a first region and a second region located above and below the central region, respectively. The first region has a first air outlet communicating with the air duct, and the second region has a second air outlet communicating with the air duct. The main body also includes an elastic connector. There are two supports connected by the elastic connector, and the two supports are symmetrically arranged. The elastic connector includes a soft rubber component and a metal component connected to the soft rubber component. Both ends of the metal component are connected to the two supports, respectively.

[0003] However, the aforementioned neck fan has the following drawbacks: The neck fan is easy to wear by prying open the two side supports. After the fan is worn on the neck, the external support force on the supports is released, and the elastic restoring force of the elastic connector allows the two side supports to automatically return to their original position. This leads to a problem, especially for users with thicker necks, where the elastic connector may cause the two side supports to exert a large clamping force on the neck, resulting in a choking situation. This needs to be improved. Utility Model Content

[0004] The purpose of this invention is to provide a neck fan that is easy to wear, which is comfortable and convenient to wear as it does not pinch the neck.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a wearable neck fan, comprising a first neck body and a second neck body, wherein an air guide cover is fixedly provided inside both the first neck body and the second neck body, a first connecting part extends from the side wall of the air guide cover on the first neck body toward the direction of the second neck body, and a second connecting part extends from the side wall of the air guide cover on the second neck body toward the direction of the first neck body, a first hinge is fixedly connected to the first neck body, and a second hinge is fixedly connected to the second connecting part, wherein the first hinge and the second hinge are rotatably connected by a pivot.

[0006] An angle limiting structure is provided at least at one point between the first connecting part and the second hinge, and between the second connecting part and the first neck hanging body. The angle limiting structure is used to limit the opening and closing angle between the first hinge and the second hinge.

[0007] By adopting the above technical solution, the user opens the first and second neck-hanging bodies relative to each other, causing the first and second hinges to rotate relative to each other to the open state. Then, the neck-hanging fan is hung upside down around the user's neck. The far ends of the first and second neck-hanging bodies hang down to the chest under their own weight. Since the first and second hinges can rotate freely relative to each other, the neck-hanging body will not exert a large clamping force on the human body when the neck-hanging fan is in use. In addition, this utility model has at least one angle limiting structure between the first connecting part and the second hinge, and between the second connecting part and the first neck-hanging body. The angle limiting structure can effectively prevent the opening angle between the first and second neck-hanging bodies from being too large, which could damage the neck-hanging fan. It has the effect of not clamping the neck when worn, making it more comfortable and convenient to wear.

[0008] The present invention is further configured such that: the first hinge includes a first fixing part fixedly connected to the first neck hanger body and a first sleeve part symmetrically distributed on both sides of the first fixing part; the second hinge includes a second fixing part and a second sleeve part extending in the middle of the second fixing part; the second fixing part is fixedly connected to the corresponding air guide cover inside the second neck hanger body; an avoidance groove is formed between the two first sleeve parts; the second sleeve part is rotatably disposed in the avoidance groove; and the rotating shaft is coaxially inserted into the first sleeve part and the second sleeve part.

[0009] By adopting the above technical solution, the second hinge can rotate around the middle of the pivot through the second sleeve portion, and the first hinge can rotate around the two ends of the pivot through the first sleeve portions on both sides. At the same time, both the first hinge and the second hinge can rotate around the same pivot, which can effectively improve the concentricity of the first hinge and the second hinge when rotating, and improve the stability of the first neck hanging body and the neck hanging body of this utility model.

[0010] A further feature of this invention is that: both ends of the rotating shaft are provided with slots, and clamps are installed in the slots; both ends of the rotating shaft are limited and stopped by the corresponding clamps at the ends of the first hinge.

[0011] By adopting the above technical solution, the detachable clamp design makes it convenient for operators to assemble or disassemble the first and second hinges.

[0012] A further feature of this invention is that the angle limiting structure includes a first limiting portion extending from the end of the first connecting portion, and the first limiting portion and the second hinge limit each other in the rotation path.

[0013] By adopting the above technical solution, when the first neck-hanging body and the second neck-hanging body rotate relative to each other to the maximum opening angle, the stopping effect of the first limiting part and the second hinge can effectively prevent the neck-hanging fan from getting stuck due to excessive opening angle, and thus prevent it from being difficult to reset.

[0014] A further feature of this invention is that the outer walls of the first limiting part and the second connecting part are arc-shaped surfaces, and the first limiting part and the second neck hanger body, as well as the second connecting part and the first neck hanger body, avoid each other on the rotation path by means of the corresponding arc-shaped surfaces.

[0015] By adopting the above technical solution, under normal use, there is a clearance between the outer wall of the arc-shaped surface of the first limiting part and the inner wall of the second neck hanger body, and there is also a clearance between the outer wall of the arc-shaped surface of the second connecting part and the inner wall of the first neck hanger body. When the parts wear down after long-term use, causing contact between the various rotating mating surfaces, the arc-shaped surface design of the outer walls of the first limiting part and the second connecting part can also improve the smoothness of sliding between the first limiting part and the second neck hanger body and between the second connecting part and the first neck hanger body, thereby reducing the noise generated during use.

[0016] A further feature of this invention is that the angle limiting structure includes a limiting block extending from the side wall of the second connecting part, and the limiting block is respectively positioned to stop the first neck hanging body and the first hinge on the rotation path.

[0017] By adopting the above technical solution, when the first neck hanger body and the second neck hanger body are far apart to the fully open state, one side of the limiting block stops and limits the first neck hanger body; when the first neck hanger body and the second neck hanger body are close to each other to the relatively closed state, the other side of the limiting block stops and limits the first hinge.

[0018] A further feature of this invention is that the first neckband body has a track groove corresponding to the limiting block, and the limiting block and the track groove are guided and cooperated.

[0019] By adopting the above technical solution, the track groove can limit the upper and lower sides of the limiting block, so that the limiting block can only slide along the length direction of the track groove, thereby improving the consistency of the direction of the relative rotation of the first hinge and the second hinge.

[0020] A further feature of this invention is that the first connecting part and the second connecting part are rotatably engaged, and a clearance space is formed between the first connecting part and the second connecting part for the first sleeve part and the second sleeve part to rotate, and the first connecting part and the second connecting part are provided with a plurality of guide ribs with arc-shaped outer end faces on the side facing the clearance space.

[0021] By adopting the above technical solution, the first sleeve portion of the first hinge and the second sleeve portion of the second hinge can rotate freely within the clearance space. At the same time, the guide ribs with the arc design on the inner wall can effectively reduce the contact area between the inner wall of the first connecting part and the second connecting part and the outer wall of the first sleeve portion and the second sleeve portion, preventing jamming between the rotating parts.

[0022] A further feature of this invention is that: the first connecting part extends to both ends with rotating parts, and the second connecting part has limiting rotating grooves at both ends corresponding to the rotating parts, and the rotating parts are constrained and rotatably disposed within the corresponding limiting rotating grooves.

[0023] By adopting the above technical solution, the opening and closing angles of the first neck-hanging body and the second neck-hanging body can be further limited, preventing the first neck-hanging body and the second neck-hanging body from getting stuck due to excessive opening angle.

[0024] A further feature of this invention is that the first connecting part and / or the second connecting part are provided with thread holes.

[0025] By adopting the above technical solution, the power cord or signal cord inside the first neck hanger body and the second neck hanger body can be connected through the wire hole.

[0026] In summary, this utility model has the following beneficial effects:

[0027] The device employs a design where air guide covers are fixedly installed within both the first and second neck-hanging bodies. A first connecting portion extends from the sidewall of the air guide cover on the first neck-hanging body towards the second neck-hanging body, and a second connecting portion extends from the sidewall of the air guide cover on the second neck-hanging body towards the first neck-hanging body. A first hinge is fixedly connected to the first neck-hanging body, and a second hinge is fixedly connected to the second connecting portion. The first and second hinges are rotatably connected via a pivot. At least one angle limiting structure is provided between the first and second connecting portions and between the second connecting portion and the first neck-hanging body. The user opens the first and second neck-hanging bodies relative to each other, causing the first and second hinges to rotate relative to each other until the device is open. The neck fan is then hung upside down around the user's neck. The far ends of the first and second neck hangers hang down to the chest under their own weight. Since the first and second hinges can rotate freely relative to each other, the neck fan does not exert a large clamping force on the user's body during use. In addition, this invention has at least one angle limiting structure between the first connecting part and the second hinge, and between the second connecting part and the first neck hanger. This angle limiting structure can effectively prevent the neck fan from being damaged due to an excessive opening angle between the first and second neck hangers. It has the effect of not clamping the neck when worn, making it more comfortable and convenient to wear. Attached Figure Description

Detailed Implementation

[0037] The present invention will be further described below with reference to the accompanying drawings.

[0038] A wearable neck fan, such as Figure 1-6 As shown, the device includes a first neck-hanging body 1 and a second neck-hanging body 2. A front cover 7 is provided at the front end of both the first neck-hanging body 1 and the second neck-hanging body 2. An air guide shell 3 is fixedly installed inside both the first neck-hanging body 1 and the second neck-hanging body 2. A first connecting portion 31 extends from the side wall of the air guide shell 3 on the first neck-hanging body 1 towards the second neck-hanging body 2, and a second connecting portion 32 extends from the side wall of the air guide shell 3 on the second neck-hanging body 2 towards the first neck-hanging body 1. A first hinge 4 is fixedly connected to the first neck-hanging body 1, and a second hinge 5 is fixedly connected to the second connecting portion 32. The first hinge 4 and the second hinge 5 are rotatably connected via a pivot 6. At least one angle limiting structure is provided between the first connecting portion 31 and the second hinge 5, and between the second connecting portion 32 and the first neck-hanging body 1. The angle limiting structure is used to limit the opening and closing angle between the first hinge 4 and the second hinge 5. A first hinge 4 is U-shaped and includes a first fixing part 41 fixedly connected to the first neck-hanging body 1 and a first sleeve part 42 symmetrically distributed on both sides of the first fixing part 41. A second hinge 5 is T-shaped and includes a second fixing part 51 and a second sleeve part 52 extending in the middle of the second fixing part 51. The second fixing part 51 is fixedly connected to the corresponding air guide cover 3 inside the second neck-hanging body 2. An avoidance groove 40 is formed between the two first sleeve parts 42. The second sleeve part 52 is rotatably disposed in the avoidance groove 40, and the rotating shaft 6 is coaxially inserted into the first sleeve part 42 and the second sleeve part 52. In addition, in this embodiment, a plurality of reinforcing ribs 36 are connected between the second connecting part 32 and the air guide cover 3 inside the second neck-hanging body 2. The reinforcing ribs 36 are used to improve the connection structure strength between the second connecting part 32 and the second neck-hanging body 2.

[0039] like Figure 3-6As shown, the rotating shaft 6 has slots 61 at both ends, and clamps 62 are installed in the slots 61. The two ends of the rotating shaft 6 are limited and stopped by the corresponding clamps 62 at the ends of the first hinge 4. The detachable clamp design of the clamps 62 makes it convenient for the operator to assemble or disassemble the first hinge 4 and the second hinge 5. The angle limiting structure includes a first limiting part 311 extending from the end of the first connecting part 31. The first limiting part 311 and the second hinge 5 are limited and stopped in the rotation path. When the first neck body 1 and the second neck body 2 rotate relative to each other to the maximum opening angle, the stopping action of the first limiting part 311 and the second hinge 5 can be used to limit the angle. To prevent the neck fan from jamming due to excessive opening angle and difficulty in resetting, the outer walls of the first limiting part 311 and the second connecting part 32 are designed as arc-shaped surfaces 33. The first limiting part 311 and the second neck body 2, and the second connecting part 32 and the first neck body 1, are fitted together by corresponding arc-shaped surfaces 33 along the rotation path to avoid interference. Under normal use, there is a clearance between the outer wall of the arc-shaped surface 33 of the first limiting part 311 and the inner wall of the second neck body 2, and also a clearance between the outer wall of the arc-shaped surface 33 of the second connecting part 32 and the inner wall of the first neck body 1. However, this clearance can be mitigated by prolonged use and wear of components. In the event of wear and tear causing contact between the rotating mating surfaces, the arc-shaped surface 33 of the outer wall of the first limiting part 311 and the second connecting part 32 can be used to maximize the smoothness of sliding between the first limiting part 311 and the second neck hanger body 2, and between the second connecting part 32 and the first neck hanger body 1, thereby reducing noise during use. The angle limiting structure includes a limiting block 321 extending from the side wall of the second connecting part 32. The limiting block 321 has two sides that respectively limit and stop the first neck hanger body 1 and the first hinge 4 in the rotation path. When the first neck hanger body 1 and the second neck hanger body 2 move away from each other... When fully open, one side of the limiting block 321 stops and limits the first neck body 1. When the first neck body 1 and the second neck body 2 approach each other to a relatively closed state, the other side of the limiting block 321 stops and limits the first hinge 4. The first neck body 1 has a track groove 11 corresponding to the limiting block 321. The limiting block 321 and the track groove 11 are guided and cooperated. The track groove 11 can limit the upper and lower sides of the limiting block 321, so that the limiting block 321 can only slide along the length direction of the track groove 11, thereby improving the direction of the first hinge 4 and the second hinge 5 when they rotate relative to each other.

[0040] like Figure 3-8As shown, the first connecting part 31 and the second connecting part 32 are rotatably engaged. A clearance space 34 is formed between the first connecting part 31 and the second connecting part 32 to allow the first sleeve part 42 and the second sleeve part 52 to rotate. Several guide ribs 35 with arc-shaped outer end faces are provided on the side of the first connecting part 31 and the second connecting part 32 facing the clearance space 34, allowing the first sleeve part 42 of the first hinge 4 and the second sleeve part 52 of the second hinge 5 to rotate freely within the clearance space 34. Simultaneously, the arc-shaped guide ribs 35 on the inner wall effectively reduce the contact area between the inner walls of the first connecting part 31 and the second connecting part 32 and the outer walls of the first sleeve part 42 and the second sleeve part 52, preventing contact between rotating parts. In case of jamming; the first connecting part 31 extends to both ends with rotating parts 312, and the second connecting part 32 has limiting rotating grooves 322 at both ends corresponding to the rotating parts 312. The rotating parts 312 are constrained and rotated within the corresponding limiting rotating grooves 322, which can further limit the opening and closing angle of the first neck hanging body 1 and the second neck hanging body 2, and prevent the first neck hanging body 1 and the second neck hanging body 2 from jamming due to excessive opening angle; in this example, the second connecting part 32 is provided with a wire hole 323. In other embodiments, a wire hole 323 can also be provided on the first connecting part 31, and the power line or signal line in the first neck hanging body 1 and the second neck hanging body 2 can be connected through the wire hole 323.

[0041] The basic working principle of this utility model is as follows: A wind guide cover 3 is fixedly installed inside both the first neck-hanging body 1 and the second neck-hanging body 2. A first connecting portion 31 extends from the side wall of the wind guide cover 3 on the first neck-hanging body 1 towards the second neck-hanging body 2. A second connecting portion 32 extends from the side wall of the wind guide cover 3 on the second neck-hanging body 2 towards the first neck-hanging body 1. A first hinge 4 is fixedly connected to the first neck-hanging body 1, and a second hinge 5 is fixedly connected to the second connecting portion 32. The first hinge 4 and the second hinge 5 are rotatably connected via a pivot 6. Simultaneously, at least one angle limiting structure is provided between the first connecting portion 31 and the second hinge 5, and between the second connecting portion 32 and the first neck-hanging body 1. The user opens the first neck-hanging body 1 and the second neck-hanging body 2 relative to each other, causing the first hinge 4 to open. Page 4 and the second hinge 5 are rotated relative to each other to the open state. Then, the neck fan is hung upside down around the user's neck. The far ends of the first neck hanging body 1 and the second neck hanging body 2 hang down to the chest under their own weight. Since the first hinge 4 and the second hinge 5 can rotate freely relative to each other, the neck hanging body 1 and the second neck hanging body 2 will not exert a large clamping force on the human body when the neck fan is in use. In addition, this utility model has at least one angle limiting structure between the first connecting part 31 and the second hinge 5, and between the second connecting part 32 and the first neck hanging body 1. The angle limiting structure can effectively prevent the opening angle between the first neck hanging body 1 and the second neck hanging body 2 from being too large, which would cause damage to the neck fan. It has the effect of not clamping the neck when worn and making it more comfortable and convenient to wear.

[0042] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
