Description

Technical Field

[0001] This invention relates to a snow goggles device with an actively defrosting thin film and its manufacturing method; particularly to a snow goggles device with an actively defrosting thin film on the glass surface and its manufacturing method; and even more particularly to a snow goggles device with an actively defrosting thin film and its manufacturing method in which the snow goggles glass surface can be directly heated. Prior Technology

[0002] Regarding conventional anti-frost goggle devices and their construction, for example, Chinese Patent Announcement No. CN-211985900, a new type of patent application for "goggles", discloses a goggle that includes a goggle body, a desiccant box, a transparent heated glass lens and a power source, and the power source includes a battery slot and a battery.

[0003] As mentioned above, the goggles body of the aforementioned CN-211985900 has an inner wall, and the desiccant box is provided on the inner wall. The goggles body and the desiccant box have a structure that can be plugged into and detached from each other, and the structure that can be plugged into and detached from each other is an arc-shaped support structure that can cooperate with each other.

[0004] As mentioned above, the goggle body of the aforementioned CN-211985900 is used to assemble the transparent heated glass lens, and a film is attached to the transparent heated glass lens, and an electric heating wire is attached to the film, and the electric heating wire is electrically connected to the power source, and the power source further includes a control switch.

[0005] Continuing from the above, the goggle body of the aforementioned CN-211985900 further includes an external power connection port, and the external power connection port has a USB interface. The goggle body also includes a temperature sensor, and the temperature sensor is electrically connected to a temperature adjustment knob.

[0006] However, the goggle device described in CN-211985900 simply forms the heating element (heating wire) within the diaphragm. As such, the heating element (heating wire) affects the line of sight of a goggle lens. Therefore, there is a need for further improvement in order to provide a photothermal conversion heating element or a similar photothermal conversion heating element on a goggle lens that does not affect the line of sight.

[0007] Another commonly used anti-frost goggle device and its manufacturing method is, for example, Canadian Patent Publication No. CA-2327006, "Anti-frost goggles and method for manufacturing the same", which discloses an anti-frost goggle device and its manufacturing method, wherein the anti-frost goggle device has a goggle body.

[0008] As mentioned above, the goggles of CA-2327006 have an inner surface and a heating element formed on the inner surface. The heating element has a pair of electrodes, which are respectively disposed on the upper portion and the lower portion of the inner surface of the goggles.

[0009] As mentioned above, the pair of electrodes in CA-2327006 are electrically connected to a power terminal via a pair of power supply lines and a pair of external wires, and the power terminal is electrically connected to a power supply means and a switch.

[0010] However, the aforementioned anti-frost goggle device in CA-2327006 simply forms the heating element on the inner surface. As such, the heating element cannot directly heat a goggle lens. Therefore, there is a need for further improvement in order to directly provide a photothermal conversion heating element or a similar element with photothermal conversion heating function on a goggle lens.

[0011] Another common optical lens structure with a side-reinforced structure is, for example, the invention patent "Side-coated Glass Polarizing Lens" in Republic of China Patent Publication No. TW-I336691, which discloses a side-coated glass polarizing lens, which includes a first glass layer, a second glass layer, a polarizing layer and a side coating.

[0012] As mentioned above, the first glass layer of the aforementioned No. TW-I336691 has a first optical surface, and the second glass layer has a second optical surface, and the second optical surface is away from the first optical surface. The polarizing layer is located between the first glass layer and the second glass layer, and the side coating is located on one side edge, and the side edge connects the edge of the first glass layer and the edge of the second optical surface.

[0013] Continuing from the above, the side coating of the aforementioned No. TW-I336691 is formed by a coating material subjected to ultraviolet irradiation and a free radical chain-linking polymerization reaction. The coating material comprises a urethane methacrylate, a reactive diluent, an adhesion promoter, and a photoinitiator. The urethane methacrylate is made from an aliphatic polyester polyol and is obtained by reacting an aliphatic polyester polyol, a hydroxyl-containing methacrylate, and a diisocyanate, and its average molecular weight is between 800 and 4500.

[0014] As stated above, the reactive diluent in the aforementioned No. TW-I336691 is selected from a methacrylate monomer, the adhesion promoter is selected from methacrylate-functionalized silane, aminomethacrylate-functionalized silane, vinyl-functionalized silane, or any combination thereof, and the photoinitiator is selected from α-hydroxy ketone, α-amino ketone, benzoin dimethyl ether, benzophenone, phosphine oxide, or any combination thereof.

[0015] Another common optical lens construction with a side-strengthened structure is, for example, the invention patent US-4076863, "Process for cutting and edging chemically pre-strengthened finished uncut lens blanks without loss of impact resistance", which discloses a reinforced lens with side coating, wherein the reinforced lens with side coating has a side edge area and a side edge coating, and the side coating is located in the side edge area.

[0016] As stated above, the side coating of US-4076863 comprises epoxy resin, alkyd resin, polyurethane resin, unsaturated polyester resin, acrylic resin, cyanoacrylate, or any combination thereof.

[0017] Another common optical lens construction with a side-reinforced structure is, for example, the invention patent "Edge coating for laminated lenses" in US Patent No. US-5220358, which discloses a laminated lens with side coating, wherein the laminated lens with side coating has a side edge region and a side edge coating, and the side coating is located in the side edge region.

[0018] As mentioned above, the side coating of US-5220358 is selected from a dimethyl silicone coating, wherein the dimethyl silicone is coblocked with a vinyl group, and the vinyl group is crosslinked via a platinum-catalyzed addition reaction.

[0019] Another common optical lens construction with a side-reinforced structure is, for example, the US Patent No. US-6860600, "Edge coated ophthalmic lenses", which discloses an ophthalmic lens with side-coating and a method for manufacturing the same. The ophthalmic lens with side-coating has a side edge, a side area, and a side coating, and the side coating is located in the side area.

[0020] As stated above, the side coating in US-6860600 is selected from a UV-curable coating, and the UV-curable coating includes an acrylate coating, and the acrylate coating of the side coating has strong surface adhesion to the side edge and weak surface adhesion to the side area.

[0021] However, the aforementioned Republic of China Patent Publication No. TW-I336691, US Patent No. US-4076863, US-5220358 and US-6860600 only disclose various optical lens structures with side coating reinforcement. Therefore, there is a need for further improvement in order to directly provide a photothermal conversion heating element or a similar element with photothermal conversion heating function on a goggle lens.

[0022] Clearly, the aforementioned Chinese Patent Publication No. CN-211985900, Canadian Patent Publication No. CA-2327006, Republic of China Patent Publication No. TW-I336691, and US Patent Nos. US-4076863, US-5220358, and US-6860600 are merely references to the technical background of this invention and to illustrate the current state of technological development; they are not intended to limit the scope of this invention.

[0023] In view of this, in order to meet the above-mentioned needs, the present invention provides a goggle device with an active defrosting film and a method for manufacturing the same. An optical substrate layer is disposed on a goggle frame, and a first surface and a second surface are disposed on the optical substrate layer. At least one transparent photothermal conversion film is disposed on the first surface, the second surface, or between the two of the optical substrate layer. The transparent photothermal conversion film absorbs light or a light beam, and the light or light beam is converted into heat energy through the transparent photothermal conversion film. The heat energy converted by the transparent photothermal conversion film is used to heat the optical substrate layer, thereby improving the technical problem that the optical substrate layer of conventional goggle devices does not have a photothermal conversion heating function.

[0055] Figure 1 shows a block diagram of a snow goggle device with an active defrosting film according to a preferred embodiment of the present invention. Referring to Figure 1, for example, the snow goggle device with an active defrosting film according to a preferred embodiment of the present invention includes a snow goggle frame 1, an optical substrate layer 2, and several transparent photothermal conversion films 3a and 3b.

[0056] Figure 2 shows a front view of a snow goggle device with an active defrosting film according to a first preferred embodiment of the present invention, which corresponds to the snow goggle device with an active defrosting film shown in Figure 1. Figure 3 shows a side view of a snow goggle device with an active defrosting film according to a first preferred embodiment of the present invention, which corresponds to the snow goggle device with an active defrosting film shown in Figure 2.

[0057] Please refer to Figures 1, 2, and 3. For example, the goggle frame 1 can be appropriately selected with a predetermined appearance profile, such as: the appearance profile of industrial goggles, the appearance profile of ski goggles, or the appearance profile of goggles for other purposes (as shown in Figure 2), a predetermined pattern, a predetermined color, or a predetermined overall structural strength.

[0058] Please refer to Figures 1, 2, and 3. For example, the goggle frame 1 can be made of a predetermined material and can be made into a predetermined shape (e.g., industrial goggles, ski goggles, or other goggle shapes). The predetermined material can be selected from a plastic material, an alloy metal material, a composite material, or any combination thereof.

[0059] Please refer to Figures 1, 2, and 3. For example, the optical substrate layer 2 may be appropriately selected from a single optical substrate layer or a composite film optical substrate layer. The optical substrate layer 2 may be appropriately selected to have a first thickness (i.e., uniform thickness or non-uniform thickness). The optical substrate layer 2 may be appropriately selected from a glass substrate layer, a plastic substrate layer, an environmentally friendly plastic substrate layer, a polymer substrate layer, a polycarbonate (PC) substrate layer, a poly(methyl methacrylate) (PMMA) substrate layer, a nylon substrate layer, or a substrate layer of a material with similar properties.

The curved lens can be selected from a cylindrical lens, a spherical lens, an ellipsoidal lens, or other curved surface mirrors. The optical substrate layer 2 can be selected from a single-layer lens, a single composite multilayer lens, an inner and outer layer combination lens, an inner and outer layer spaced combination lens, or other types of lenses.

The first surface 21 of the optical substrate layer 2 can be selected as a front surface (e.g., an outer surface), and the second surface 22 of the optical substrate layer 2 can be selected as a rear surface (e.g., an inner surface).

[0063] Please refer to Figures 1, 2 and 3. For example, the materials of the goggle frame 1 and the optical substrate layer 2 can be selected as the same material (e.g., materials with similar properties) or different materials (e.g., heterogeneous materials) to provide the same or various different material properties.

[0064] Please refer to Figures 1, 2, and 3 again. For example, the transparent photothermal conversion films (the gray areas shown in Figures 2 and 3) 3a and 3b can be integrally formed on the goggle frame 1. For example, the transparent photothermal conversion films 3a and 3b can be formed on the goggle frame 1 as a thin film. Alternatively, the transparent photothermal conversion films 3a and 3b can also be integrally formed on the optical substrate layer 2. For example, the transparent photothermal conversion films 3a and 3b can also be formed on the optical substrate layer 2 as a thin film.

[0065] Please refer again to Figures 1, 2, and 3. For example, the transparent photothermal conversion films 3a and 3b can be made from a photothermal conversion material, and the photothermal conversion material can be an infrared photothermal conversion material. In another preferred embodiment of the present invention, the infrared photothermal conversion material comprises a plurality of tungsten oxide particles, a plurality of composite tungsten oxide particles, a plurality of titanium dioxide particles, a plurality of antimony-doped tin dioxide-coated titanium dioxide particles, or any combination thereof.

[0066] Referring again to Figures 1, 2, and 3, for example, in another preferred embodiment of the present invention, the photothermal conversion material of the transparent photothermal conversion films 3a and 3b can be selectively added to the goggle frame 1, the optical substrate layer 2, or both. In another preferred embodiment of the present invention, the photothermal conversion material of the transparent photothermal conversion films 3a and 3b can selectively contain several nano-particles.

[0067] Please refer to Figures 1, 2 and 3 again. For example, the transparent photothermal conversion films 3a and 3b of the preferred embodiment of the present invention have good light transmittance, and the transparent photothermal conversion films 3a and 3b also have properties such as scratch resistance, chemical corrosion resistance, antistatic properties or flexibility.

[0068] Figure 4 is a schematic flowchart illustrating a preferred embodiment of the manufacturing method of a snow goggle device with an active defrosting film according to the present invention, corresponding to the snow goggle device with an active defrosting film in Figures 1, 2, and 3.

[0070] Please refer again to Figures 1, 2, and 3. For example, in another preferred embodiment of the present invention, the transparent photothermal conversion film 3a can also be a semi-transparent photothermal conversion film or an opaque photothermal conversion film, which can be disposed on a suitable position (e.g., outer surface, inner surface, or other suitable position) of the goggle frame 1 using appropriate technical means (e.g., sputtering, spraying, coating, material addition, or other configuration methods).

[0071] Please refer again to Figures 1, 2, 3 and 4. For example, the manufacturing method of the snow goggle device with an active defrosting film of the preferred embodiment of the present invention includes step S3: Next, for example, the photothermal conversion material of the transparent photothermal conversion films 3a and 3b can be selected to appropriately absorb a light ray or a light beam from the outside environment using appropriate technical means, and the light ray or light beam is converted into heat energy through the photothermal conversion material of the transparent photothermal conversion films 3a and 3b.

[0072] Please refer to Figures 1, 2, 3 and 4 again. For example, the manufacturing method of the goggle device with an active defrosting film of the preferred embodiment of the present invention includes step S4: Next, for example, the optical substrate layer 2 or the goggle frame 1 can be appropriately heated by using the heat energy converted by the photothermal conversion material of the transparent photothermal conversion film 3a and 3b with appropriate technical means. In this way, the optical substrate layer 2 or the goggle frame 1 can be prevented from frosting, fogging or both in a low temperature environment.
