Description

Technical Field

[0001] This invention relates to the field of sun hat technology, and more particularly to a molded fan hat. Background Technology

[0002] In existing technologies, fan caps are typically made of fabric or other materials through a sewing process. This manufacturing method results in poor overall integrity, a lack of crispness, and a tendency for the seams to crack, affecting both appearance and lifespan. To improve the overall integrity, polypropylene (PP) is usually used for injection molding. This requires injection molding / extrusion molding or secondary compression molding on a single sheet / strip, which is a complex process with poor crease recovery. Furthermore, it results in high mold and product costs, low yield and pass rates, high requirements for material composition, and susceptibility to breakage. Summary of the Invention

[0003] To address the problems of the prior art, the present invention provides a molded fan cap, which is integrally molded, has good integrity, low cost, and is not easily damaged.

Detailed Implementation

[0019] The present invention will be further described below with reference to specific embodiments.

[0020] refer to Figure 1-11 A molded fan cap includes a cap body 1, at least one fan assembly 4, a corresponding battery 9, and a control assembly 8. The cap body 1 includes a headband 2 and a brim 3, and the cap body 1 is molded at least at the brim 3. In this embodiment, the headband 2 and the brim 3 can be integrally molded as needed; or the headband 2 can be sewn onto the molded brim 3. The brim 3 is provided with a molded fan mounting groove 5 for mounting the fan assembly 4. The fan mounting groove 5 is located on the upper end face of the brim 3, and the lower end face of the brim 3 is provided with a molded air intake 6 and an air exhaust 7 at the corresponding position of the fan mounting groove 5. The exterior of the cap body 1 is also provided with a decorative surface 13 at least at the brim 3. The decorative surface 13 can be provided only at the brim 3, or the exterior of the cap body 1 can be provided with a decorative surface 13 at both the brim 3 and the headband 2. Decorative surface 3 is used to conceal the fan assembly 4, battery 9 and control assembly 8 inside the cap body, keeping the cap body 1 aesthetically pleasing.

[0021] The molding process is simple, easy to process, and has better overall integrity. The molded fan cap has a clean appearance with no stitching. By using high-temperature resistant and tough aerospace materials as the cap core, the desired shape can be directly pressed out, while maintaining good stiffness of specific parts. It also has good crease recovery performance and a long service life. Compared with conventional polypropylene (PP) materials, the mold cost is lower and the finished product qualification rate is higher.

[0022] The fan mounting slot 5, air inlet 6 and air outlet 7 are integrally molded, and the molded cap body can be directly installed with the fan assembly 4, which is very convenient.

[0023] Preferably, the cap body 1 is further provided with a molded battery mounting slot 10 for installing the battery; the cap body 1 is also provided with a molded control component mounting slot 11 for installing the control component 8. The battery mounting slot 10 and the control component mounting slot 11 can be provided on the brim 3 or the headband 2. The molded cap body can directly install the control component 8 and the battery 9 at the corresponding positions.

[0024] The hat body 1 has a decorative surface 13 on its exterior. After the fan assembly is installed on the molded brim 3, the decorative surface 13 is placed on the upper end of the brim 3, covering the brim to decorate and shield the fan assembly, making the overall appearance more aesthetically pleasing and providing some protection for the fan assembly. The decorative fabric has clearance holes (not shown in the figure) near the air intake 6 and air exhaust 7 to avoid affecting the ventilation of the air intake 6 and air exhaust 7.

[0025] The hat body 1 includes a first layer of fabric 101, a second layer of fabric 102, a first sponge layer 103 disposed between the first layer of fabric and the second layer of fabric, a hat core layer 104, and a second sponge layer 105.

[0026] The inner side of the hatband 2 is provided with a detachable sweat towel 12, which can also be a quick-molded sweat towel. When the user wears the hat, the sweat towel 12 is in direct contact with the hatband 2, so the hat will not be soiled by sweat. The sweat towel 12 is detachable and can be removed, washed and replaced at any time.

[0027] The sweat towel 12 is also made of compressed sponge in the middle and fabric on both sides. The sweat towel 12 has magnetic components on at least two sides, and the headband 2 has magnets inside that can be magnetically connected to the magnetic components. The headband 2 can have the magnetic components pre-installed in the first and second layers of fabric, and then be molded together with the headband body to fix the magnetic components between the first and second layers of fabric. The magnetic components are then magnetized and magnetically connected to the sweat towel 12.

[0028] The fan assembly 4 and the corresponding fan mounting slot 5 are provided in two, symmetrically arranged on both sides of the cap 3, respectively located on the left half 16 and the right half 17.

[0029] The fan assembly 4 includes: a housing 401, which is fixed on the brim 3 and connected to the inlet end of the duct cover 14; and a fan blade 402, which is located inside the housing and driven by a motor (not shown in the figure) inside the housing.

[0030] An exhaust duct 15 is provided between the housing 401 and the exhaust port 7.

[0031] The fan blades 402 and the motor are respectively housed in the housing. The fan blades 402 take in air from the center through the air intake 6 and exit air radially away from the center. Then, the air is discharged to the face through the exhaust duct 15 and exhaust port 7 in the air duct cover 14. In addition, this arrangement also reduces the overall volume of the fan assembly 4.

[0032] The housing includes a top shell 4011 and a bottom shell 4012. The bottom shell 4012 is snapped into the bottom of the top shell 4011 and is connected to the air intake 6. The top shell 4011 is connected to the inlet end of the air duct cover 14. The fan blade 402 is located between the top shell 4011 and the bottom shell 4012. The rotation of the fan blade generates negative pressure, which draws air in through the air intake 6 and then guides it to the corresponding exhaust port 7 through the exhaust duct 15.

[0033] Preferably, multiple air intakes 6 can be provided, located at corresponding positions of the fan 401. When the fan 401 is activated, air is drawn in from the air intakes 6. Multiple air intakes 6 result in faster air intake and better suction. Air enters the air intake duct 14 and is discharged from the exhaust port 7 through the exhaust duct 15. Multiple exhaust ducts 15 can be provided, and at least one guide plate 18 is provided at the exhaust port 7. The guide plate 18 can guide the airflow towards the headband 2, so that more airflow blows towards the cheeks when worn.

[0034] As one implementation method, for example Figure 6 Multiple air vents 7 are provided and located near the outer edge of the brim 3. When worn, both the downward-facing air intake vent 6 and the air vent 7 can face the face. The air vents 7 are located on the left half 16 and the right half 17 of the brim 3, respectively. The fan assembly has multiple air ducts 15 arranged radially. The air ducts 15 are distributed in a divergent manner, and each air duct 15 is connected to an air vent 7.

[0035] As another implementation method, for example Figure 7 Multiple exhaust vents 7 are located near the headband 2, and both the downward-facing air intake vent 6 and exhaust vent 7 can face the face when worn. The fan assembly has multiple exhaust ducts 15 radially arranged, which are concentrated on the side near the headband and connected to the exhaust vents 7.

[0036] The above description is merely an optional embodiment of the present invention and does not limit the patent scope of the present invention.
