[0004] Cooling effect: When working in hot weather or high-temperature environments, wearing a fan hat can effectively reduce the head and body temperature, provide a certain sense of coolness, and prevent heat injuries such as heat stroke;

[0005] Targeted cooling: The design of the fan hat makes the wind directly act on the head, which is an important part of the human body for heat dissipation. Directly cooling the head is more effective than other cooling methods and can quickly take away heat;

[0006] Safety: In some industrial environments, such as high-temperature working places like welding and casting, wearing a fan hat can not only help workers cool down and prevent heatstroke, but also play a certain protective role to avoid the head being injured by high-temperature substances splashing.

[0007] Currently, the hats with fans are basically in the form of direct blowing, resulting in air flow only on the face, and other positions on the head cannot feel the air flow, thus greatly reducing the cooling effect. Content of the Utility Model

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0029] Refer to the figure Figures 1-4 A fan hat with a ring-shaped head and multiple air outlets structure comprises a hat body 10, one end of the hat body 10 is provided with a brim 11, a blower fan 12 is provided on the side of the brim 11 facing the face, and the edge of the blower fan 12 is fixedly assembled with the brim 11 by a first screw, and one end of the blower fan 12 is provided with an air outlet;

[0030] An air duct 13 is provided at the end of the cap body 10, and the air inlet of the air duct 13 is connected to the air outlet of the blast fan 12, and the edge of the air duct 13 is fixedly assembled with the surface of the brim 11 by a second screw. The air duct 13 includes a lower half channel 20 and an upper half channel 21, and the lower half channel 20 is respectively fitted with the inner side of the port of the cap body 10 and the surface of the brim 11, and the lower half channel 20 and the upper half channel 21 are mutually clamped and installed;

[0031] The outer wall surface of the upper channel 21 is provided with a mounting sleeve 24, and the interior of the mounting sleeve 24 is an internal threaded surface. The mounting sleeve 24 is fixedly assembled with the brim 11 by a second screw. The lower channel 20 and the upper channel 21 are both two-way flow-guiding structures, and the other end of the two-way flow-guiding structure is a closed structure.

[0032] It should be further explained that the inner wall surface of the lower half channel 20 and the inner wall surface of the upper half channel 21 are both provided with a curved inner wall 23, and the curved inner wall 23 can reduce wind resistance, reduce noise, and improve the smoothness of airflow.

[0033] Further, it should be noted that the number of the mounting sleeves 24 is four, and they are symmetrically distributed along the inlet position of the air duct 13. The mounting sleeves 24 can cooperate with the second screws to stably install the air duct 13 on one side surface of the face side of the brim 11.

[0034] Further, it should be noted that a lower diversion protrusion 30 is arranged at the inner wall port position of the lower half channel 20, which can divert and guide the air flow.

[0035] Further, it should be noted that an upper diversion protrusion 31 is arranged at the inner wall surface port position of the upper half channel 21. The upper diversion protrusion 31 is tightly attached to the lower diversion protrusion 30. A complete diversion structure is formed by the two diversion protrusions distributed up and down, so that when the air flow enters the air duct 13, it can be evenly diverted on both sides.

[0036] Further, it should be noted that a plurality of air nozzles 22 are arranged on the surface of the upper half channel 21. The air nozzles 22 are symmetrically distributed along the inlet position of the air duct 13. The air nozzles 22 are convex structures and are integrally formed with the upper half channel 21. The air nozzles 22 can eject the air flow and blow the air towards the specified face or head.

[0037] Further, it should be noted that the inlet of the air duct 13 includes a limit frame 40 and a limit plate 41. The limit frame 40 and the lower half channel 20 are of an integral structure;

[0038] The number of the limit plates 41 is two, and they are respectively arranged on both sides of the upper half channel 21 and are of an integral structure with the upper half channel 21. The limit plates 41 are tightly attached to the limit frame 40. The limit plates 41 and the limit frame 40 can cooperate with the outlet position of the blower fan 12 to ensure the stable transportation of the air flow.

[0039] Working mode: By arranging the air duct 13 structure at the end of the blower fan 12, the air flow blown out by the blower fan 12 can be centrally sent into the interior of the air duct 13 and ejected through the air nozzles 22, so that the face and head can be cooled and dissipated heat to the greatest extent, and the situation of irregular diffusion caused by the influence of external air flow will not occur, greatly improving the utilization rate of the air flow.

[0040] By arranging a diversion structure at the end of the air duct 13, it is ensured that after the air flow is transported out, it can be stably diverted evenly on both sides. The inner wall surface of the air duct 13 is an arc-shaped inner wall 23, which can improve the smoothness of the air flow, reduce the wind resistance and reduce the generation of noise.

[0041] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, making equivalent substitutions or changes, shall be covered by the protection scope of the present utility model.
