The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0044] Example 1

[0045] As shown in Figures 1-4, this application discloses a multi-directional blowing neck fan, including a support 10 that can be worn on the neck of a human body, and the support 10 has a shell 101 located on both sides of the neck of a human body.

[0046] Each housing 101 has a first housing 20 and a second housing 30 connected to each other. The first housing 20 is provided with an air inlet 21 and a receiving cavity 22 communicating with the air inlet 21. A fan assembly 23 is provided in the receiving cavity 22. The end of the receiving cavity 22 near the second housing 30 is open to form an air outlet 24.

[0047] A partition 40 is provided between the first housing 20 and the second housing 30. The partition 40 divides the air outlet 24 into a first air outlet 241 and a second air outlet 242. The first air outlet 241 is located on the side of the partition 40 closer to the neck of the human body, and the second air outlet 242 is located on the side of the partition 40 away from the neck of the human body. An air duct 31 is provided inside the second housing 30. The air duct 31 extends along the length of the second housing 30. A third air outlet 32 ​​is provided on the second housing 30. The third air outlet 32, the air duct 31 and the second air outlet 242 are connected in sequence.

[0048] The second housing 30 has a recessed air guide groove 33 on the side facing the human neck. The air guide groove 33 is recessed away from the human neck and extends along the length of the second housing 30. The inner wall of the air guide groove 33 extends to the partition 40. By setting the air guide groove 33 and extending the inner wall of the air guide groove 33 to the partition 40, the wall effect of the partition 40 and the air guide groove 33 can be utilized. During use, the air blown out of the first air outlet 241 is smoothly transported to a more distant end along the inner wall of the partition 40 and the air guide groove 33, thereby increasing the human neck experience.

[0049] An air outlet 24 is provided with an air outlet mesh cover 25, and the air outlet mesh cover 25 has multiple air guide holes 251 on its upper ring. By setting the air outlet mesh cover 25, the air outlet mesh cover 25 has multiple air guide holes 251 on its upper ring. By utilizing the guiding effect of the air guide holes 251, the air is blown out of the air guide holes 251 more evenly, avoiding turbulence and improving the blowing effect.

[0050] The motor on the fan assembly 23 is mounted on the air outlet grille 25.

[0051] The air inlet 21 is located at the end of the first housing 20 that is away from the second housing 30.

[0052] The first housing 20 is provided with an air inlet mesh cover 26 at the end away from the second housing 30, and the air inlet 21 consists of multiple mesh holes on the air inlet mesh cover 26.

[0053] The cross-section of the air duct 31 gradually decreases along the direction of air flow; by setting the cross-section of the air duct 31 to gradually decrease along the direction of air flow, the air pressure at different points in the air duct 31 is made more consistent, thereby making the air volume of the third air outlet 32 ​​uniform.

[0054] The third air outlet 32 ​​consists of multiple strip-shaped holes distributed along the length of the second housing 30.

[0055] The third air outlet 32 ​​can also be a single strip-shaped hole extending along the length of the second housing 30, or it can be multiple small holes spaced closely together.

[0056] The first housing 20 has a first inner housing 201 and a first outer housing 202. A first air outlet 241 is provided on the first inner housing 201. The second housing 30 has a second inner housing 301 and a second outer housing 302. A third air outlet 32 ​​is provided on the second inner housing 301. The first inner housing 201, the second inner housing 301 and the partition 40 are integrally formed. The first outer housing 202 and the second outer housing 302 are integrally formed.

[0057] The working principle of the multi-directional airflow neck fan of this application is as follows: when the fan assembly 23 is activated, the fan assembly 23 draws the outside space into the accommodating cavity 22 through the air inlet 21. Part of the drawn-in air is blown directly out from the first air outlet 241 to the air guide slot 33 to dissipate heat from the neck of the human body; the other part passes through the second air outlet 242, the air duct 31, and the third air outlet 32 ​​in sequence to dissipate heat from the head of the human body.

[0058] In summary, this application comprises a first housing 20 and a second housing 30. The first housing 20 has a receiving cavity 22 communicating with the air inlet 21, and a fan assembly 23 is provided in the receiving cavity 22. The end of the receiving cavity 22 near the second housing 30 is open to form an air outlet 24. A partition 40 is provided between the first housing 20 and the second housing 30 to divide the air outlet 24 into a first air outlet 241 and a second air outlet 242. The second housing 30 has an air duct 31 and a third air outlet. 32. The third air outlet 32, the air duct 31, and the second air outlet 242 are connected in sequence. When in use, the fan assembly 23 draws outside air into the receiving cavity 22 through the air inlet 21. Part of the drawn air is blown directly out of the first air outlet 241 to cool the neck of the human body; the other part passes through the second air outlet 242 and the air duct 31 in sequence and is blown out of the third air outlet 32 ​​to cool the head of the human body. This achieves multi-directional airflow, a large airflow range, and envelops the head and neck of the human body, resulting in better airflow effect.

[0059] Example 2

[0060] To avoid repetitive description, in this embodiment, only the differences from Embodiment 1 will be described. The main difference between this embodiment and Embodiment 1 is that the bracket 10 in this embodiment also includes a rear shell 102, and the two ends of the rear shell 102 are respectively snapped and connected to the two shells 101.

[0061] As shown in Figures 5-10, the bracket 10 also includes a back shell 102 located behind the neck, with both ends of the back shell 102 snapped into two shells 101. The back shell 102 makes wearing the garment easier, and its snap-fit ​​connection eliminates the need for fasteners, resulting in higher assembly efficiency. Furthermore, the presence of the back shell 102 at the back of the neck and the two shells 101 on either side of the neck prevents pressure on the neck, improving wearing comfort. The snap-fit ​​connection between the back shell 102 and the shells 101 eliminates the need for fasteners, enhancing the overall appearance and aesthetics. The reduced number of openings and fasteners also minimizes hard-to-clean areas, reducing bacterial growth.

[0062] In one embodiment, the rear shell 102 and the housing 101 are connected by snap-fit ​​connectors 60. The snap-fit ​​connector 60 includes an insertion end 61 and a snap-fit ​​end 62. The insertion end 61 is inserted tightly into the rear shell 102, and the friction between the insertion end 61 and the inner wall of the rear shell 102 prevents the insertion end 61 from disengaging from the rear shell 102. The snap-fit ​​end 62 is snap-fitted into the housing 101. During assembly, the two snap-fit ​​connectors 60 are respectively inserted into both ends of the rear shell 102, and then the two housings 101 are respectively snap-fitted into the snap-fit ​​ends 62 of the two snap-fit ​​connectors 60, achieving rapid assembly.

[0063] For example, the snap-fit ​​end 62 is provided with a snap hook 622, and a snap-fit ​​seat 35 is provided inside the housing 101. The snap-fit ​​seat 35 is located at one end of the second inner housing 301 near the rear housing 102. The snap-fit ​​seat 35 is integrally formed with the second inner housing 301 and has an annular structure. After the snap-fit ​​end 62 passes through the snap-fit ​​seat 35, the snap hook 622 snaps into the edge of the snap-fit ​​seat 35 to achieve a snap-fit ​​connection. The snap-fit ​​seat 35 is also provided with a snap hole 351, and the snap-fit ​​end 62 is also provided with a snap groove 621. The snap hole 351 and the snap groove 621 are connected. The inner sidewall of the second outer housing 302 near the snap-fit ​​seat 35 is provided with a snap protrusion 36. The snap protrusion 36 passes through the snap hole 351 and engages with the snap groove 621, which can realize the snap-fit ​​connection of the rear housing 102 and the second inner housing 301, further improving assembly efficiency.

[0064] In one embodiment, as shown in Figures 7-10, a guide plate 50 is provided inside the housing 101. The guide plate 50 is fixedly connected to the partition plate 40 and the housing 101. The guide plate 50, the partition plate 40, and the housing 101 together form an air duct 31. Exemplarily, the guide plate 50 is bonded or integrally formed inside the second inner housing 301. Along the direction of airflow, the area of ​​the space enclosed by the guide plate 50 and the second inner housing 301, i.e., the air duct 31, gradually decreases and becomes zero at the end. This improves the airtightness of the air duct 31 formed by the partition plate 40, the guide plate 50, and the second inner housing 301, thereby enhancing the blowing effect of the third air outlet 32.

[0065] Please refer to Figures 7-10. Multiple third air outlets 32 have equal areas. Multiple air guide plates 34 protrude from the inner wall of the housing 101 where the third air outlets 32 are located. For example, the second inner housing 301 has multiple air guide plates 34 protruding from the inner wall of the third air outlets 32. The multiple air guide plates 34 and the multiple third air outlets 32 are staggered along the direction of airflow. The air guide plates 34 are used to intercept the airflow within the air duct 31, thereby ensuring that the airflow from different third air outlets 32 is approximately equal, improving the user experience. Along the direction of airflow, the height of the air guide plates 34 protruding from the inner wall of the housing 101 gradually decreases. That is, as the area of ​​the air duct 31 decreases, the protrusion height of the air guide plates 34 correspondingly decreases, leaving sufficient space for the airflow within the air duct 31 to flow smoothly downstream, preventing excessive air interception by one or more upstream air guide plates 34, which could lead to uneven airflow from the multiple third air outlets 32.

[0066] Optionally, as shown in Figures 9-10, the air guide plate 34 has an arc-shaped structure, with its concave surface facing the second air outlet 242, i.e., the concave surface faces the direction of airflow. The air in the air duct 31 flows to the third air outlet 32 ​​located upstream of the air guide plate 34 under the guidance of the concave surface of the air guide plate 34, and is discharged from the third air outlet 32. Setting the air guide plate 34 as an arc-shaped structure further enhances the airflow guiding effect.

[0067] As shown in Figures 5 and 6, a protective perforated plate 27 is also provided on the housing 101. The protective perforated plate 27 is located upstream of the air outlet of the air outlet mesh cover 25 to prevent the user's hair from getting caught. The protective perforated plate 27 has a hollow structure and is integrally formed with the first inner housing 201. The protective perforated plate 27 has multiple strip-shaped holes, thereby providing effective protection without affecting the air outlet effect. In other embodiments, the protective perforated plate 27 may also have multiple matrix-shaped square or round holes.

[0068] The above description is merely an optional embodiment of this application and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of disclosure in this application is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the above-described disclosed concept. For example, technical solutions formed by substituting the above features with (but not limited to) technical features with similar functions disclosed in this application.
