Description

Technical Field

[0001] This invention relates to a multi-functional protective hat that can block solar heat radiation, belonging to the field of protective hat technology. Background Technology

[0002] Since people live in different environments, their choices of protective hat styles also vary. Meeting people's needs is the responsibility of science and technology workers.

[0003] Regarding the use of aluminum foil for human protection, there are currently no officially marketed products. The main technical basis is related to theories in quantum mechanics. Aluminum foil has a very low absorption and emissivity of solar thermal radiation energy, approximately 0.02~0.06s. For engineers, this data should be reliable. The engineer's responsibility is to find suitable scenarios, create appropriate technical methods, and find suitable materials, adhering to the characteristics of "wave-state heat transfer." Every detail must be meticulously executed to verify the theories of quantum mechanics through the product's excellent insulation effect. See also: *Aluminum Foil Insulation Materials and Their Applications*—by Huang Qiming, published by Zhejiang Science and Technology Press, first edition February 1985.

[0004] Section 6 Thermal Insulation Properties of Nameplate Emissivity of three-dimensional foil The thermal insulation properties of foil are manifested in the thermal radiation characteristics of its surface. Aluminum is a metal with extremely poor temperature radiation properties. Polished aluminum surfaces can be viewed as white bodies that do not emit or absorb thermal radiation, which can be explained from the perspective of quantum mechanics.

[0005] Thermal radiation can freely penetrate the surrounding dry air without producing a direct effect. It can only raise the temperature of objects that absorb radiation instead of reflecting it. ... Electrons in metals have an energy level distribution. Exciting an electron from a bound state to a conduction state requires energy absorption, and when the electron is captured again and becomes bound, this energy is released. Aluminum has a large energy level difference between its free electrons, and its atoms do not easily emit quanta. When exposed to external thermal radiation, energy is not easily captured by bound electrons. Therefore, aluminum foil has particularly low absorption and emission of radiation energy. Since the emissivity ε of aluminum foil is very close to its absorptivity α, it is considered a gray body in thermal calculations.

[0006] Polished aluminum surface, ε=0.02~0.06. Summary of the Invention

[0007] The technical problem to be solved by this invention is: how to make a protective hat that can block strong solar heat radiation, is ventilated, is shrinkable, and has a beautiful appearance.

[0008] To solve the above-mentioned technical problems, the technical solution of the present invention is to provide a multi-functional protective hat that can block solar heat radiation. The hat is characterized by comprising a top, a body, and a brim. The top is supported and fixed to the body via a suspended bracket and aluminum foil.

The positioning seats are symmetrically arranged on both sides with the positioning openings facing outwards. The suspended rod is installed in the pre-drilled circular hole in the middle of the vertical plate of the positioning seat with an interference fit and is fixed with locking pins. There is approximately a 2 mm gap between the bottom of the suspended rod and the inner side of the aluminum foil cloth.

[0011] Preferably, the top exhaust pipe has a cylindrical structure, with multiple outwardly protruding tabs at both the upper and lower ends. The top cover plate has a bowl-shaped structure, with multiple protruding tabs around its perimeter, protruding outwardly and upward at 45°. The top cover plate is fixedly connected to the protruding tabs at the upper end of the top exhaust pipe, and the outer diameter of the top cover plate is the same as the outer diameter formed by the outer edges of the protruding tabs at the upper end of the top exhaust pipe. The multiple outwardly protruding tabs at the lower end of the top exhaust pipe are fixedly seated on the ventilation clamp box.

[0012] Preferably, the top exhaust pipe has a cylindrical inner wall with an inner diameter larger than the outer side of the multiple vent holes provided on the venting clamp box; the colored side of the aluminum foil cloth above the top cover plate faces upward and the smooth side faces downward; the suspended supports of the upper and lower parts of the cap body are all rigid thin plastic tubes, and the suspended supports at the bends are flexible thin plastic tubes; the cap body suspended supports and the cap brim suspended supports are all thin plastic tubes.

[0013] Preferably, the outer side of the aluminum foil cloth on the outside of the brim suspension bracket is connected with plain weave cloth, and the inner side of all the brim suspension brackets is connected with colored plain weave cloth; the inner side of all the hat tube suspension brackets is provided with colored plain weave cloth.

[0014] Preferably, the colored plain weave fabric inside the hat stand suspension bracket is positioned only from the bottom to the top of the vertical tube of the hat stand suspension bracket.

[0015] Preferably, the upper end of the hat tube suspension bracket is evenly divided according to the center point of the center box as the standard point, and the division is the same as that of each protrusion of the ventilation clamp on the upper part of the center box; the upper end of the aluminum foil cloth on the outside of the hat tube body is fixed on multiple downwardly inclined protrusions on the outer extension of the ventilation clamp on the upper part of the center box.

[0019] Preferably, the upper end of the brim is inclined outward at an angle of less than 90° to the lower part of the hat body.

[0020] The protective helmet of this invention employs guided natural ventilation, the mechanism of which is as follows: airflow is influenced by three factors: 1) temperature, 2) pressure, and 3) density. Since solar thermal radiation rises from the east in the morning and sets in the west in the evening, when this radiation reaches the Earth's surface, the Earth absorbs and reflects some of the radiation energy. As the Earth absorbs this radiation, its surface temperature rises, and the temperature of the air above it also increases. As solar thermal radiation continues to irradiate the ground, the ground temperature continues to rise, and the air above the ground continues to rise. This airflow creates wind. Since thermal radiation has no effect on wind, this wind is the power source for the protective helmet's natural ventilation, enhancing the guided natural ventilation. The helmet body and top are equipped with guided natural ventilation measures. After the helmet is worn, air naturally enters from the bottom of the helmet body, passes over the head, and then exits into the atmosphere through the exhaust port on the top of the helmet, significantly improving head comfort.

[0021] The inventiveness of this invention is as follows: The suspended bracket for the cap body consists of a central suspended rod and positioning seats at both ends. The suspended bracket is fixed to the inner surface of the aluminum foil cloth via the positioning seats at both ends, arranged vertically. The suspended rod is installed in the pre-drilled hole in the middle of the vertical plate of the positioning seats at both ends. There is a gap between the suspended rod and the inner surface of the aluminum foil cloth. By using the suspended bracket method, approximately 99% of the inner surface of the aluminum foil cloth can be suspended, ensuring that an air gap is formed between the inner surface of the aluminum foil cloth and the skin of the human head. This method fully protects the thermal radiation characteristics of the aluminum foil surface and greatly improves the insulation efficiency of the aluminum foil cloth against thermal radiation.

[0022] Compared with the prior art, the present invention has the following beneficial effects: This invention is very effective at blocking solar heat radiation, which can enhance the comfort of the head.

[0023] The present invention uses a cap-shaped suspended bracket arranged vertically inside the aluminum foil cloth, with the colored side of the aluminum foil cloth on the outside and the smooth side of the aluminum foil cloth on the inside. When solar radiation energy shines on the aluminum foil cloth, most of the smooth side of the aluminum foil cloth is in contact with an air layer, which is a "wave-state heat transfer". At this time, the absorption coefficient of the aluminum foil is very small, about 0.02~0.06.

[0024] The attractive shape of this invention is a major feature. It retains the curvature of the cap while maintaining its retractable flexibility. Through research and analysis of the transforming plastic tube, this plastic tube can be modified into a highly flexible plastic tube. Using this flexible plastic tube in the curved part allows the protective cap to be retracted from its unfolded state into a smaller, elongated cylindrical shape with very little force. Moreover, the unfolding is also very smooth, solving the overall shrinkage problem and thus solving the problem of convenient carrying. Attached Figure Description

[0026] To make the present invention more apparent and understandable, preferred embodiments are described in detail below with reference to the accompanying drawings.

[0027] This invention provides a stylish and multifunctional protective hat that can block solar heat radiation, such as... Figures 1-3 As shown, the protective cap consists of three parts: the top 1, the body 2, and the brim 3. The top 1 is located at the top, the body 2 in the middle, and the brim 3 at the bottom. The top 1 is supported and fixed to the body 2 by a bone support and aluminum foil. The upper end of the brim 3 is movably connected to the lower outer side of the body 2 by a bone support and a soft plastic sheet. The corresponding outer side of the lower bone support of the body 2 is connected to the upper outer side of the brim 3 by an adjusting strap 11. Straps 4 are connected to both ends of the bottom of the body 2.

[0028] The top of the cap 1 includes multiple top exhaust pipes 7 and aluminum foil wrapped around the outside of all the top exhaust pipes 7. All the top exhaust pipes 7 form a cylindrical structure. The upper and lower ends of the multiple top exhaust pipes 7 are provided with multiple outwardly 90° protrusions. A top cover plate 9 is provided above the top exhaust pipes 7. The aluminum foil is fixed on the top cover plate 9. Multiple lateral exhaust ports 8 are provided above the top exhaust pipes 7 and below the top cover plate 9. The top cover plate 9 has a bowl-shaped structure. Multiple protrusions are also provided around the top cover plate 9, protruding outward and upward at about 45°. The top cover plate 9 is fixedly connected to the protrusions at the upper end of the top exhaust pipes 7. The outer diameter of the top cover plate 9 is the same as the outer diameter formed by the outer edge of the protrusions at the upper end of the top exhaust pipes 7. The multiple outwardly 90° protrusions at the lower end of the top exhaust pipes 7 are fixed on the ventilation clip box.

[0029] The cap body 2 is divided into an upper conical body and a lower cylindrical body. The transition between the upper and lower parts is a bend. The inclined outer edge of the conical body is covered with inclined aluminum foil. The aluminum foil on the outside of the top exhaust pipe 7 covers the inclined aluminum foil on the cap body 2 from the bottom outwards. The bone support on the cap body 2 is an integral structure formed by multiple cap suspension supports 10. The outer side of the integral structure of all cap suspension supports 10 is covered with aluminum foil. The ventilation clip box includes a ventilation clip 12 and a central box 5. After the cap body bone support is installed, the central box 5 is connected to the ventilation clip 12 as a whole. The upper ends of all cap suspension supports 10 are evenly distributed and fixed in the central box 5. The ventilation clip 12 has multiple ventilation holes 6 evenly distributed to allow airflow to enter the internal space of the cap top 1. All cap suspension supports 10 are vertically evenly distributed. In this embodiment, a total of 8 cap suspension supports 10 are provided. The inner side of the cap suspension supports 10 is covered with colored plain weave fabric.

[0030] The inner wall of the cylindrical shape formed by the top exhaust pipe 7 is located outside the vent hole 6 set on the venting clamp box; the colored side of the aluminum foil cloth above the top cover plate 9 faces upward and the smooth side faces downward; the bone support of the upper and lower parts of the cap body 2 is a rigid thin plastic tube, and the bone support at the bend is a flexible thin plastic tube.

[0031] The upper end of the brim 3 is located at the lower part of the hat body 2 and is connected to the hat body 2 at an outward 30-degree angle. The brim 3 includes the outermost plain weave fabric, the aluminum foil fabric inside the plain weave fabric, multiple brim suspension brackets inside the aluminum foil fabric, and the colored plain weave fabric inside the plastic tube.

[0032] The lower inner sides of the cap body 2 are connected to straps 4 with snap buckles. The upper ends of the eight cap suspension brackets 10 set inside the aluminum foil of the cap body 2 are fixed inside the central box 5. Taking the center point of the central box 5 as the standard point, the upper ends of the eight cap suspension brackets 10 are set according to the eight-phase equal division method, which is the same as the eight-phase equal division of the eight protrusions 14 of the ventilation clamp 12 on the upper part of the central box 5. The upper part of the eight vertical cap suspension brackets 10 in the cap body 2 is a flexible tube, and the middle and lower part is a vertical tube. About three horizontal flexible tubes are set between every two vertical tubes in the middle and lower part.

[0033] The colored plain weave fabric inside the hat stand suspension bracket 10 extends from the bottom to the top of the vertical tube of the hat stand suspension bracket 10. The inner side of the curved section of the hat stand suspension bracket 10 is not covered with colored plain weave fabric. Air flowing upwards from below can enter the upper part of the hat body 2 through the curved section and enter the top exhaust pipe 7 of the hat top 1 through the vent hole 6 on the vent plate 12. It then exits into the atmosphere through the exhaust port 8 at the top of the top exhaust pipe 7. This effectively dissipates heat from the head and any other heat entering the hat, ensuring a comfortable feeling for the head. The top exhaust pipe 7, the hat stand suspension bracket 10, and the brim suspension bracket are all thin plastic tubes.

[0034] The upper end of the aluminum foil cloth on the outside of the cap body 2 is fixed to the eight protrusions 14 on the outer end of the ventilation clamp 12 above the ventilation clamp box 5 (extending pieces at a downward 30-degree angle).

[0035] The eight cap-shaped suspension supports 10 inside the aluminum foil of the cap body 2 have flexible tubes at the top and vertical tubes in the middle and lower parts. When the protective cap needs to be retracted, the top 1 of the cap remains fixed, and the cap body 2 is subjected to inward and downward pressure from the user's hand. Under this inward and downward pressure, the flexible plastic tubes at the top of the cap body 2 will naturally retract inward and downward, and then be secured with the straps 4. When the protective cap needs to be unfolded, the straps 4 need to be loosened, and the protective cap can be easily unfolded.

[0036] When the protective hat of the present invention is worn, the human head will continuously radiate heat outward. Since the top of the hat 1 and the hat body 2 are equipped with guided ventilation measures, the following is the composition: In the design of the hat body 2, eight vertical hat body suspension brackets 10 are set on the inner side of the aluminum foil cloth. The gap between these eight suspension brackets is the air channel for air to flow from bottom to top. Air will naturally enter from the bottom of the hat body 2, pass through the head, and then be discharged to the atmosphere from the exhaust port on the exhaust pipe of the top of the hat 1, which can significantly improve the comfort of the head.

[0037] Note: The above components can be connected by glue or other methods.
