Description

Technical Field

[0001] This utility model relates to the field of fan technology, specifically a neck fan with an adjustable angle in all directions. Background Technology

[0002] As neck fans continue to develop, users now come in various sizes, body types, and genders, each with different needs regarding the airflow position and intensity. Currently, neck fans have relatively fixed airflow angles with limited adjustment, or offer only a single option for horizontal or vertical rotation, failing to meet the diverse needs of different user groups for airflow angle and comfort when blowing air from different positions. Utility Model Content

[0003] The purpose of this invention is to improve the user experience by providing a neck fan with an adjustable angle in all directions.

[0004] To address the aforementioned problems, this utility model proposes a neck fan with an adjustable angle in all directions, comprising a neck shell and side shells connected to both ends of the neck shell. The side shells are provided with universal heads at their ends, and the universal heads are connected to the neck shell in an all-directional manner. An air outlet assembly is provided inside the side shells.

[0005] Furthermore, an air outlet component is provided inside the neckband shell.

[0006] Furthermore, the air outlet assembly includes a sealed air chamber, a fan is installed inside the sealed air chamber, and an air outlet is also provided on the sealed air chamber.

[0007] Furthermore, the sealed air cavity is provided with a narrow section corresponding to the air outlet, and the width of the narrow section gradually decreases from the fan to the far end.

[0008] Furthermore, multiple guide bones are provided within the elongated section, extending from the interior of the elongated section towards the air outlet.

[0009] Furthermore, the universal head is integrally formed on the side shell.

[0010] Furthermore, the neck hanger shell includes a fixed base and a face shell. The end of the face shell is provided with a spherical receiving cavity. The spherical receiving cavity is provided with a first curved groove corresponding to the universal head. The fixed base is provided with a second curved groove that cooperates with the first curved groove. The universal head is enclosed between the first curved groove and the second curved groove.

[0011] Furthermore, a limit stop is provided on the outside of the universal joint, and an opening groove corresponding to the limit stop is provided on the first curved groove.

[0012] Compared with the prior art, the present invention has at least the following beneficial effects:

[0013] Compared to traditional one-piece U-shaped neck fans, this one is divided into three parts: a neck-hanging outer shell that can be hung around the neck, and side shells that extend to both sides of the neck. The side shells are connected to the neck-hanging outer shell by universal joints at their ends, and the air outlet components are housed inside the neck-hanging outer shell. This design allows for angle adjustment according to the user's needs, providing a more personalized user experience and increasing the fan's flexibility. Attached Figure Description

Detailed Implementation

[0021] The present invention will now be further described with reference to the accompanying drawings.

[0022] like Figures 1 to 9As shown, this utility model provides a neck fan with an adjustable angle in all directions. Compared to traditional one-piece U-shaped neck fans, this neck fan is divided into three parts: a neck hanging shell 1 that can be hung on the neck, and side shells 2 that extend to both sides of the neck. The three shells together form a U-shape. The middle of the neck hanging shell 1 is made of soft rubber, which allows for easy wearing and widens the U-shaped opening for easy hanging around the neck. The side shells 2 are connected to the neck hanging shell 1 by universal joints 3 at their ends, and the air outlet assembly 4 is located inside the neck hanging shell 1. This design allows for angle adjustment according to the user's needs, providing a more personalized user experience and improving the fan's flexibility.

[0023] Optionally, an air outlet component 4 (such as...) can also be installed inside the neckband shell 1. Figure 8 , Figure 9 This allows the back of the neck to enjoy the airflow, improving the user experience.

[0024] More specifically, the air outlet assembly 4 includes a sealed air chamber 5 independent of the side shell, which can effectively maintain the airtightness of the air duct to reduce air volume loss and improve the perceived air volume. Furthermore, a fan 501 is installed in the sealed air chamber 5, which can provide strong power support and generate greater air pressure. The side of the sealed air chamber 5 is provided with a large-flow air outlet 502, which can distribute the airflow to a larger area, accelerate the cooling speed, and allow users to experience a more comfortable cooling effect.

[0025] In a preferred embodiment, the sealed air cavity 5 is provided with a narrow section 503 corresponding to the air outlet 502, and the width of the narrow section 503 gradually decreases from the fan 501 to the distal end (e.g., Figure 6 This design is because the airflow is larger closer to the fan 501 and relatively smaller further away. By gradually reducing the width of the narrow section 503, the airflow speed gradually increases after passing through the narrow section 503, thus achieving a larger wind speed at a greater distance. In this way, while maintaining a stable overall airflow speed, the wind speed distribution at various locations is more balanced, improving the uniformity of the airflow.

[0026] In a preferred embodiment, a plurality of guide ribs 504 are provided within the elongated section 503, and the guide ribs 504 extend from the interior of the elongated section 503 toward the air outlet 502 (e.g., ...). Figure 6 , Figure 7 The guide rib 504 can guide airflow in a specific direction, further enhancing the directional nature of the airflow and making the fan perform better.

[0027] In this embodiment, the universal head 3 is integrally formed onto the side housing 2, which improves the overall strength and rigidity and simplifies the assembly process. Of course, in addition to this method, the universal head 3 can also be a separate component, assembled and fixed by the front and rear covers of the side housing 2, as in the spherical receiving compartment 6 described below.

[0028] In this embodiment, the neck hanger shell 1 includes a fixed base 101 and a face shell 102. A spherical receiving cavity 6 is provided at the end of the face shell 102. The spherical receiving cavity 6 has a first curved groove 601 corresponding to the universal joint 3. A second curved groove that mates with the first curved groove 601 is provided on the fixed base 101. The universal joint 3 is enclosed between the first and second curved grooves. In this design, the universal joint 3 is also correspondingly set as a ball head, which achieves omnidirectional rotation through the first and second curved grooves. Of course, it is not limited to a ball head; it can be any shape within the first and second curved grooves, as long as it achieves omnidirectional rotation. Preferably, a spherical shape is used because it provides better stability and balance.

[0029] In this embodiment, a limit stop 301 is provided on the outside of the universal head 3, and an opening slot 602 corresponding to the limit stop 301 is provided on the first curved surface groove 601. In this design, the limit stop 301 on the outside of the universal head 3 ensures that the universal head 3 can rotate flexibly while also limiting its rotation range to a certain extent, preventing unnecessary rotation under unrestricted conditions. The opening slot 602 on the first curved surface groove 601 effectively engages the universal head 3 with the limit stop 301. When the universal head 3 rotates to a certain position, the opening slot 602 contacts the curved surface, preventing the universal head 3 from rotating further, thus limiting the rotation angle of the universal head 3. This design not only effectively controls the rotation range of the universal head 3 but also avoids unnecessary impacts during movement, improving the convenience and stability of the product.

These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without inventive effort, and these embodiments will all fall within the protection scope of the claims of this utility model.
