Description

Technical Field

[0001] This utility model relates to the field of clothing and accessories technology, and in particular to a double-layer heat-insulating, ventilated, breathable, foldable sun hat. Background Technology

[0002] In modern life, people are increasingly engaging in outdoor activities, whether it's outdoor sports, travel, or daily commutes, inevitably exposing themselves to sunlight. The damage caused by ultraviolet (UV) radiation to human skin cannot be ignored, potentially leading to sunburn, skin aging, pigmentation, and even increasing the risk of skin cancer. Therefore, sun protection products have become an important choice for protecting oneself from UV damage, with sun hats being particularly popular due to their convenience and practicality.

[0003] Currently, there are many types of sun hats on the market, but they all have some problems: 1. In terms of heat insulation, the materials of many sun hats' caps are not effective in blocking heat transfer, causing the wearer's head to feel stuffy quickly under the sun; 2. In terms of breathability, most sun hats are poorly designed, preventing air from circulating smoothly inside. Some cap materials are too thick or sealed, lacking sufficient ventilation holes, and even those with ventilation holes are not positioned or large enough to meet heat dissipation needs. Furthermore, the brim design of existing sun hats is also flawed. Many brims are too short, failing to provide sufficient sun protection for large areas of skin such as the face and neck. Additionally, some brims have unstable structures, easily sagging at the edges, which not only affects sun protection but may also obstruct vision and inconvenience the wearer. Moreover, such sagging brims hinder airflow, further exacerbating the stuffiness. When worn for extended periods, the wearer's head sweats profusely due to the stuffiness and lack of ventilation. Since the sweat cannot evaporate in time, it sticks to the skin, causing great discomfort and severely impacting the user experience of the sun hat. Therefore, a double-layered, heat-insulating, ventilated, and breathable foldable sun hat is needed to solve these problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a double-layer heat-insulating, ventilated, breathable, foldable sun-protective hat.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a double-layer heat-insulating, ventilated, breathable, foldable sun-protective hat, comprising a cap, a brim, and a mesh inner layer. The cap includes an arc-shaped top and a frustum-shaped body. The bottom of the frustum-shaped body is connected to the inner side of the brim. A certain gap is left between the arc-shaped top and the mesh inner layer. An insert is installed in the center of the top of the arc-shaped top. A pull bolt passes through the middle of the insert. A triangular locking block is installed on the top of the pull bolt. The arc-shaped top is laid on the bottom of the insert. Ventilation holes are arranged in a ring on the top and bottom of the side of the frustum-shaped body. A padding layer is provided between the top of the arc-shaped top and the bottom of the insert, and the padding layer is fitted onto the pull bolt.

[0006] Preferably, in the double-layer heat-insulating, ventilated, breathable, foldable sun hat of this utility model: the opening of the padding layer is smaller than the diameter of the insert.

[0007] Preferably, in the double-layer heat-insulating, ventilated, breathable, foldable sun hat of this utility model: a fastening ring is installed at the bottom of the headpiece, a top support arm is arranged in an outer ring array outside the fastening ring, the top support arm is connected to a flexible support arm, one end of the top support arm is movably connected to the fastening ring, and the other end of the top support arm is connected to one end of the flexible support arm.

[0008] Preferably, in the double-layer heat-insulating, ventilated, breathable, foldable sun hat of this utility model: a bottom connector is installed at the bottom end of the pull tab, and a support rod is arranged in a ring around the bottom connector. One end of the support rod is movably connected to the bottom connector, and the other end of the support rod is movably connected to the other end of the flexible support arm.

[0009] Preferably, in the double-layer heat-insulating, ventilated, breathable, foldable sun hat of this utility model: the other end of the support rod is provided with a side support arm and is movably connected to the top of the side support arm; the bottom end of the support arm is movably connected to one end of the brim support arm; an auxiliary support column is installed between the support rod and the brim support arm; and the auxiliary support column is movably connected to both the support rod and the brim support arm.

[0010] Preferably, in the double-layer heat-insulating, ventilated, breathable, foldable sun hat of this utility model: a brim channel is provided on the brim, and the brim support arm is installed in the brim channel.

Beneficial effects

[0012] This invention provides a sun hat with significant advantages in heat insulation and ventilation. The cap features a double-layer design with an arched top and a mesh inner layer, separated by a gap. The top and bottom of the frustum-shaped cap also incorporate ventilation holes and a mesh inner layer, creating double-sided heat insulation. Simultaneously, the ventilation holes at the top and bottom of the cap allow free airflow within the cap, forming excellent heat dissipation channels. When outside air enters, it exchanges hot and cold air through these ventilation holes, quickly removing heat and moisture generated on the head, greatly reducing stuffiness and preventing sweat from sticking to the skin, thus providing a comfortable environment for the wearer.

[0013] This sun hat offers numerous structural advantages. The widened brim significantly increases the sun protection area, better protecting the face, neck, and other skin from UV rays. Double-layered mesh ventilation holes along the lower edge of the brim work in conjunction with the ventilation holes on the cap to create vertical air circulation, further enhancing ventilation. Furthermore, the supporting frame of the entire hat resembles a folding umbrella, with convenient opening and closing via latches and triangular locking mechanisms. An openable / closeable structure at the top makes it easy to carry. This unique design not only ensures the stability and functionality of the sun hat during use but also allows for easy storage when not in use, improving its practicality and convenience, and greatly enhancing the user experience.

[0021] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0022] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific Implementation

[0023] Reference Figure 1-5 A double-layer heat-insulating, ventilated, breathable, foldable sun hat includes a cap 1, a circular brim 2, and a mesh inner layer 16. The cap 1 includes an arc-shaped top 8 and a truncated cone-shaped body 18. The bottom of the truncated cone-shaped body 18 is connected to the inner side of the brim 2. The mesh inner layer 16 is placed inside the truncated cone-shaped body 18 and is adapted to the size of the truncated cone-shaped body 18. A certain gap is left between the truncated cone-shaped body 18 and the mesh inner layer 16. An insert 5 is installed in the center of the top of the arc-shaped top 8. Ventilation holes 3 are arranged in a ring on the top and bottom of the side of the truncated cone-shaped body 18. The ventilation holes 3 can be made by using mesh fabric in the part where the truncated cone-shaped body 18 is located. A padding layer 4 is provided between the top of the arc-shaped top 8 and the bottom of the insert 5. The padding layer 4 is fitted on the pull tab 7, and the opening of the padding layer 4 is smaller than the diameter of the insert 5.

[0024] The size of ventilation hole 3 should be set according to the actual situation. The figure shown is for reference only. Figure 1 As shown, the entire hat's supporting frame consists of eight sets of supporting components, similar to the existing umbrella structure, allowing the entire hat to be opened and closed like an umbrella. It should be noted that the arc-shaped top 8 is laid on the top of the entire supporting frame, while the mesh inner layer 16 is laid inside the entire supporting frame, and the top and bottom joints 15 of the mesh inner layer 16 are attached together.

[0025] A bolt 7 runs through the middle of the insert 5, and a triangular locking block 6 is installed on the top of the bolt 7. An arc-shaped top 8 is laid at the bottom of the insert 5. The insert 5, bolt 7, and triangular locking block 6 are similar to the opening structure of a traditional umbrella. The entire support frame is pulled by the bolt 7. The triangular locking block 6 on one side of the bolt 7 is similar to that of an umbrella and is used for limiting the position.

[0026] The bottom of the insert 5 is equipped with a fastening ring 13, and the outer ring of the fastening ring 13 has a top support arm 17. One end of the top support arm 17 is movably connected to the fastening ring 13, and the other end of the top support arm 17 is connected to one end of the flexible support arm 9.

[0027] The bottom end of the bolt 7 is equipped with a bottom connector 15, and the outer ring of the bottom connector 15 has a support rod 14. The fastening ring 13 and the bottom connector 15 have similar structures. They both have a circular channel on the body with 8 mounting slots. One end of the support rod 14 or the top support arm 17 has a through hole. When one end of the support rod 14 or the top support arm 17 is installed in the mounting slot, it is movably connected by a wire locking element, such as an iron wire, passing through the through hole.

[0028] One end of the support rod 14 is movably connected to the bottom connector 15, and the other end of the support rod 14 is movably connected to the other end of the flexible support arm 9. The other end of the support rod 14 is movably connected to the top of the side support arm 10. The bottom end of the support arm 10 is movably connected to one end of the brim support arm 12. An auxiliary support column 11 is installed between the support rod 14 and the brim support arm 12. The auxiliary support column 11 is movably connected to both the support rod 14 and the brim support arm 12.

[0029] The flexible support arm 9, side support arm 10, auxiliary support column 11, support rod 14, bottom joint 15, and fastening ring 13 are all located between the cap 1 and the mesh inner layer 16. Eight cap brim channels 19 are provided on the cap brim 2, and eight cap brim support arms 12 are installed in the eight cap brim channels 19. The cap brim support arms 12 can extend and retract the cap brim channels along the channels.

[0030] It should be noted that the eight brim support arms 12 at the bottom of the entire frame have eight radially arranged brim channels 19 sewn onto the corresponding fabric. The eight brim support arms 12 are installed inside and can extend and retract along the radial channels to open or close. The top and bottom of the truncated cone-shaped hat body 18 are made of mesh fabric for ventilation and breathability. At the same time, the inner mesh layer 16 is also made of mesh fabric. This double-layer heat-insulating, ventilated, breathable, and easy-to-carry sun hat mainly achieves functions such as heat insulation, ventilation and breathability, and easy carrying through a special structural design.

[0031] The sun hat includes several components such as a cap 1 and a brim 2. The cap 1 has an arched top 8 and a frustum-shaped body 18. There are ventilation holes 3 around the top and bottom of the frustum-shaped body 18, which allow air to flow inside the cap. When outside air enters, it exchanges hot and cold air through these ventilation holes 3, thereby achieving the purpose of heat dissipation.

[0032] The entire hat's supporting frame consists of eight support components, similar to an umbrella structure, allowing it to open and close like an umbrella. The switch is located at the top of the hat and is operated via a pull tab 7 running through the center of the insert 5. A triangular locking block 6 is installed on one side of the pull tab 7 for locking, similar to the locking principle of an umbrella. This structure allows the sun hat to maintain a stable shape during use and can be easily folded up for convenient carrying when not in use.

[0033] It should be noted that when the pull bolt 7 is pulled, it acts as the main force-applying component, exerting an upward pulling force on the entire frame system. The pull bolt 7 is connected to the insert 5, which transmits the pulling force to the fastening ring 13. The triangular locking block 6 on one side of the pull bolt 7 plays a key limiting role, interacting with the internal structure of the frame (similar to the principle of an umbrella switch), causing the pull bolt 7 to move in a specific direction, ensuring stable opening action, similar to an umbrella limiting device, preventing excessive displacement or misalignment of the pull bolt 7. The force transmitted from the insert 5 to the fastening ring 13 is diffused outward through the top support arm 17. The top support arm 17 is connected to the flexible support arm 9, which extends outward under the pulling force. At the same time, the bottom joint 15 at the bottom of the pull bolt 7 is affected by the upward pulling force, and the support rods 14 in its outer ring array begin to move. One end of the support rod 14 is connected to the flexible support arm 9, working together with the flexible support arm 9 to extend and transmit the force to the periphery of the cap body. The eight brim support arms 12 installed inside the brim 2 are subjected to tension from the support rod 14 and the flexible support arm 9. Because the brim support arms 12 can extend and retract radially within the brim channel 19, they extend outwards under force, causing the brim 2 to gradually open. The auxiliary support column 11 at the bottom of the support rod 14, near the brim support arm 12, plays a crucial mechanical support role during the opening process. Working in conjunction with the brim support arms 12 and the brim channel, it shares the tension and converts it into a supporting force for the brim support arms 12, enhancing the stability of the brim 2 in the open state and ensuring that the brim 2 maintains its shape and position correctly after being fully opened, without sagging or deforming. When closing the sun hat, a downward pressure opposite to the direction of the opening tension is applied to the pull bolt 7. The triangular locking block 6 still acts as a limit, ensuring that the pull bolt 7 moves downwards along a predetermined trajectory, preventing the frame from jamming or misaligning during the closing process. As the pull rod 7 is pressed down, the bottom connector 15 drives the support rod 14 to retract inward. The support rod 14 pulls the flexible support arm 9 and the brim support arm 12 toward the center. At the same time, the top support arm 17 retracts toward the center under the action of the fastening ring 13, transmitting the force back to the insert 5. The brim support arm 12 is subjected to inward squeezing force in the air duct 3, causing the brim 2 to gradually close. The auxiliary support column 11 assists in adjusting the force distribution to ensure that the force is even when each component retracts, avoiding excessive local force that could damage the components. The entire closing process is the reverse of the opening process. The mechanical relationships of each component cooperate with each other, allowing the sun hat to smoothly switch between open and closed states, making it convenient to carry and store.

[0034] In summary:

[0035] 1. In this device, an opening and closing structure is added to the top of the hat for convenient carrying. The widened brim 2 increases the sun protection area and provides ventilation from all four sides. In addition, the top and bottom of the truncated cone-shaped hat body 18 and the inner mesh layer 16 are made of mesh fabric for ventilation and breathability. This is equivalent to the top and bottom of the side wall in the middle of the hat having a certain height of mesh fabric, which further enhances the ventilation and breathability effect. This effectively improves the problems of existing sun hats, such as the cap not insulating heat and not breathable, short brim, drooping around the edges, and not allowing light to pass through, making them stuffy and sweaty in summer, and causing sweat to stick to the skin. This provides users with a more comfortable wearing experience.

[0036] 2. A fastening ring 13 is installed at the bottom of the insert 5. A top support arm 17 is arranged in a ring outside the fastening ring 13. One end of the top support arm 17 is connected to a flexible support arm 9. A bottom connector 15 is installed at the bottom end of the pull bolt 7. A support rod 14 is arranged in a ring outside the bottom connector 15. One end of the support rod 14 is movably connected to the bottom connector 15. The other end of the support rod 14 is movably connected to the other end of the flexible support arm 9. The other end of the support rod 14 is also movably connected to the top of the side support arm 10. One end of the brim support arm 12 is movably connected to the bottom end of the support arm 10. An auxiliary support column 11 is installed between the support rod 14 and the brim support arm 12. The auxiliary support column 11 is movably connected to both the support rod 14 and the brim support arm 12. These components together form a support frame, ensuring the overall structural stability and functional realization of the sun hat.
