Description

Technical Field

[0001] This utility model relates to the field of fan hat technology, and in particular to a concealed fan hat with a built-in direct airflow duct in the visor. Background Technology

[0002] To improve wearing comfort and enhance heat dissipation, various integrated fan-equipped hats have appeared on the market. Existing fan-equipped hats typically employ one of the following two mainstream designs: External fan type: This design mounts the motor and fan blades directly on the outside of the hat, usually in the center or front of the hat, with the battery pack also externally mounted on the outside of the hat. This structure has obvious drawbacks: First, the protruding fan module greatly detracts from the overall appearance of the hat, making it look bulky and unsightly; second, the fan is directly exposed, posing a risk of snagging on objects, resulting in lower safety; finally, the axial fan produces dispersed airflow with low air pressure, and the airflow is directed downwards, mainly affecting a localized area on the top of the head, resulting in limited heat dissipation efficiency, and the strong wind blowing through the hair creates a poor user experience.

[0003] Under-brim fan type: Another design involves suspending a small fan under the brim of the hat, with the fan outlet facing the face. While this avoids some damage to the hat's appearance, the suspended component can obstruct vision and create a feeling of oppression. Furthermore, the airflow only covers a small area of ​​the face and cannot effectively cool the main heat-generating areas such as the forehead.

[0004] In summary, existing fan-equipped hats generally suffer from the following common shortcomings: Exposed structure and poor aesthetics: Whether it is the fan on the top of the hat or the fan hanging under the brim, its functional components are not integrated with the hat body, which seriously affects the aesthetics of the hat as an everyday garment.

[0005] Low heat dissipation efficiency: The motor and fan blades are directly mounted on the top of the hat, resulting in low air pressure and short air delivery distance. The airflow cannot effectively cover the main heat dissipation areas of the head, resulting in poor heat dissipation. Summary of the Invention

[0006] To address the aforementioned issues, this invention provides a concealed fan cap with a built-in direct airflow duct in the visor. By integrating and concealing the fan and other functional components inside the visor, the cap maintains its original aesthetic appearance while effectively enhancing airflow intensity and surface area through the use of multiple blowers, thus increasing heat dissipation.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is: a concealed fan cap with a built-in direct airflow duct in the visor, comprising a cap body and a visor. The visor surface has an accommodating cavity, and the accommodating cavity contains a circuit board and a switch, a rechargeable battery, a charging interface, and several blower fans connected to the circuit board. The blower fans have airflow ducts that extend to the outside of the accommodating cavity and face the inside of the cap body. The accommodating cavity also has a cover plate that can be detachably covered on its surface.

[0008] Specifically, the blower fan surface is provided with an air suction mesh, and the cover plate surface is provided with an air suction avoidance hole corresponding to the air suction mesh, so that the air suction mesh of the blower fan extends from the accommodating cavity to the outside of the cover plate.

[0009] Specifically, the cover plate is also provided with a switch clearance hole corresponding to the switch and a charging clearance hole corresponding to the charging interface. The switch passes through and extends outside the switch clearance hole, and the charging interface is located inside the charging clearance hole.

[0010] Specifically, the accommodating cavity is provided with several mounting slots, and the inner surface of the cover plate is provided with mounting posts corresponding to the mounting slots. The cover plate is fixed in the mounting slots by inserting the mounting posts.

[0011] Specifically, the drive motor of the blower fan is a three-phase six-pole motor.

[0012] Specifically, the receiving cavity is opened from the upper or lower surface of the cap flap.

[0013] The beneficial effects of this utility model are as follows: by providing a receiving groove on the surface of the cap visor, and providing several blower fans in the receiving groove, with the blower fan air ducts extending to the outside of the receiving cavity and facing the inside of the cap, and by providing a detachable cover plate to cover the surface of the receiving cavity, the blower fan effectively enhances the blowing intensity and blowing surface, and increases the heat dissipation effect by using multiple blower fans to blow air directly into the inside of the cap, while maintaining the original aesthetic appearance of the cap.

[0017] Figure 4 This is a schematic diagram of the structure of Embodiment 2.

[0018] Figure 5 This is an exploded view of Example 2. Detailed Implementation

[0019] The present invention will now be described in further detail with reference to the accompanying drawings.

[0020] Example 1 Please see Figure 1-3 This embodiment discloses a concealed fan cap with a built-in direct airflow duct in the visor, including a cap body 1 and a visor 2. The upper surface of the visor 2 has a receiving cavity 21, and a circuit board 3, a switch 4, a rechargeable battery 5, a charging interface 6, and a blower fan 7 connected to the circuit board 3 are installed in the receiving cavity 21. The rechargeable battery 5 provides working power to the blower fan 7 through the circuit board 3. The charging interface 6 charges the rechargeable battery 5 through the circuit board 3 after being powered by an external power source. The switch 6 is used to control the operation of the blower fan 7.

[0021] The aforementioned components are housed within the accommodating cavity 21 and concealed by the cover plate 22, maintaining the hat's original appearance and aesthetic appeal. To further enhance the hat's aesthetics, in this embodiment, the visor is thicker in the middle and thinner at the outer edge, making the overall appearance of the hat indistinguishable from a regular hat with a visor. Simultaneously, the blower fan 7 has an airflow duct 71 extending to the outside of the accommodating cavity 21 and facing the inside of the hat body 1. When the hat is worn, the airflow duct 71 directly faces the wearer's head. Compared to an external fan, the blower fan 7 significantly improves both the airflow intensity and the airflow area, enhancing the heat dissipation effect. This embodiment employs a dual blower fan 7 design. The number of blower fans 7 can be adjusted as needed to enhance the cooling effect.

[0022] In a preferred embodiment, the blower fan 7 has an air intake mesh 72 on its surface, and the cover plate 22 has an air intake clearance hole 221 corresponding to the air intake mesh 72 on its surface. This allows the air intake mesh 72 of the blower fan 7 to extend from the accommodating cavity 21 to the outside of the cover plate 22. By opening the air intake clearance hole 221, the blower fan 7 can directly draw in outside air and blow it out through the air blowing channel without obstruction when it is working, which effectively increases the blowing intensity and improves heat dissipation.

[0023] In a preferred embodiment, the cover plate 22 is also provided with a switch clearance hole 222 corresponding to the switch 4 and a charging clearance hole 223 corresponding to the charging interface 6. The switch 4 passes through and extends outside the switch clearance hole 222. When it is necessary to turn the blower fan 7 on or off, the switch 4 on the surface of the cover plate 22 can be pressed directly. The charging interface 6 is located inside the charging clearance hole 223. When charging is required, an external power source can be inserted into the charging clearance hole 223 and connected to the charging interface 6.

[0024] In a preferred embodiment, the accommodating cavity 21 is provided with a plurality of mounting grooves 211, and the inner surface of the cover plate 22 is provided with mounting posts 224 corresponding to the mounting grooves 211. The cover plate 22 is fixed in the mounting grooves 221 by the mounting posts 224. Its installation structure is simple, and the cover plate can be pulled out by force when it needs to be disassembled.

[0025] As a preferred implementation, the drive motor of the blower fan 7 in this embodiment adopts a three-phase six-pole motor, which can effectively reduce the fan power. Compared with the single-phase four-pole motors used in the hat-top external fan and the hat-brimmed hanging fan, the battery life is longer and the user experience is enhanced.

[0026] Furthermore, according to the traditional hat manufacturing process, holes corresponding to the receiving cavity 21 are first cut into the fabric, and then the fabric is sewn onto the hat body. This method often results in misalignment between the holes in the fabric and the receiving cavity 21 when the fabric is sewn onto the hat surface. That is, the pre-cut holes in the fabric are not aligned with the receiving cavity 21, making it impossible to install the cover plate 22. This leads to a high defect rate and ultimately higher product costs.

[0027] In this embodiment, the fabric is first sewn onto the surface of the hat, and then the fabric on the outside of the accommodating cavity 21 is cut with a laser so that the accommodating cavity 22 is fully exposed, which facilitates the installation of the cover plate 22. This processing technology can greatly improve production efficiency and reduce the defect rate, and ultimately effectively manage product costs.

[0028] Example 2 Please see Figure 4-5 The difference between this embodiment and Embodiment 1 is that the accommodating cavity 21 is opened from the lower surface of the cap tongue 2. Correspondingly, the cover plate 22 covers the lower surface of the cap tongue 2.

[0029] To increase the firmness of the cover plate 22, in this embodiment, the surface of the cover plate 22 is also provided with a number of connecting holes 225, and the receiving groove 21 is provided with a corresponding threaded groove 226. The connecting holes 225 of the cover plate 22 correspond to the threaded groove 226 of the receiving groove 21, and are fixed by screws.

[0030] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
