Description

Technical Field

[0001] This application relates to the field of swimming goggle technology, and in particular to a lightweight diving mask with a one-piece frame. Background Technology

[0002] Traditional diving goggles use a double-frame clamping structure or a rubber coating process to fix the lens to the frame. However, the inner and outer frames clamp the lens within a ring-shaped step on the inner edge of the frame, and the lens is assembled and fixed by a snap-fit ​​structure inside the frame. This requires precision assembly of multiple components, and the snap-fit ​​structure is complex. A single frame and lens are integrated into a single design using a rubber coating process. Although this simplifies the number of parts, it also means that the lens cannot be replaced independently, and the product is easily damaged during disassembly. Moreover, this structure is prone to loosening after long-term use, which leads to a decrease in the seal between the lens and the frame and affects the waterproof performance.

[0021] To make the objectives, features, and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0022] The inventors discovered through analysis of existing technologies that conventional diving masks use a double-frame clamping structure or a rubber coating process to fix the lens to the frame. However, the lens is clamped within the annular step on the inner edge of the frame by the inner and outer frames and is assembled and fixed by the snap-fit ​​structure inside the frame. This requires the precise assembly of multiple components, and the snap-fit ​​structure is complex. While the single frame and lens are integrated into a single design using a rubber coating process, which simplifies the number of parts, this process also makes it impossible to replace the lens independently, and the product is easily damaged during disassembly.

[0023] In the embodiments of this application, addressing the shortcomings of existing diving masks such as complex installation, inability to replace damaged lenses, and high usage costs, this application proposes a single-piece frame lightweight diving mask, including a frame, lens, strap, and soft rubber face shield. The inner edge of the frame has a recessed annular step for mounting the lens, and the outer edge of the inner edge of the frame has several retaining blocks. The lens is detachably mounted on the annular step, and an installation seam is provided between the lens and the retaining blocks. The soft rubber face shield is embedded in the installation seam. Connecting portions are provided at both ends of the frame, and the strap is connected to the frame through these connecting portions. By providing the annular step and retaining blocks, the lens is embedded in the annular step, and the soft rubber face shield is embedded between the lens and the retaining blocks, creating a relatively fixed, stable, and easy-to-install connection between the frame, lens, and soft rubber face shield, facilitating both installation and replacement of parts.

[0024] Reference Figure 1-3 The image shows a one-piece frame lightweight diving mask, including a frame 101, a lens 102, a strap 103, and a soft rubber face shield 104.

[0025] The inner edge of the frame 101 is recessed with an annular step 301 for mounting the lens 102, and the outer side of the inner edge of the frame 101 is provided with a plurality of retaining blocks 201; the lens 102 is detachably mounted on the annular step 301; an installation seam is provided between the lens 102 and the retaining blocks 201; the soft rubber mask 104 is embedded in the installation seam.

[0026] The frame 101 has connecting parts 105 at both ends, and the lens strap 104 is connected to the frame 101 through the connecting parts 105.

[0027] It should be noted that the annular step 301 is a recessed annular step 301 on the inner edge of the frame 101. It serves as the mounting reference for the lens 102. Its shape is adapted to the edge contour of the lens 102, which can accurately position the lens 102 and ensure that the lens 102 will not shift during use.

[0028] The soft rubber mask 103 is integrated with other components by being embedded in the mounting seam. The mounting seam serves to fix the soft rubber mask 103, preventing it from falling off during use. The retaining block 201 simultaneously holds the soft rubber mask 103 and the lens 102, thus fixing the lens 102, frame 101, and soft rubber mask 103 relatively in place. At the same time, the soft rubber mask 103 itself has a certain degree of elasticity. After being embedded in the mounting seam, it can fill the gap between the lens 102 and the retaining block 201, improving the sealing of the diving mask and effectively preventing water from entering the mask. The soft rubber mask 103 comes into contact with the face, and its embedded installation method ensures a smooth transition with the lens 102 and frame 101, avoiding any impact on wearing comfort due to abrupt connection structures.

[0029] The connecting portions 105 at both ends of the frame 101 serve as the mounting interfaces for the mask strap 104. The mask strap 104 is connected to the frame 102 via these connecting portions 105, thereby securing the diving mask to the user's head. The design of the connecting portions 105 must meet certain strength requirements to withstand the tensile force generated by the mask strap during wear, ensuring that the diving mask does not detach from the head during use.

[0030] The following will further describe a one-piece frame lightweight diving mask in this exemplary embodiment.

[0031] In one embodiment of this application, the number of the retaining blocks 201 is 6, and the 6 retaining blocks 201 are evenly distributed on the outer side of the inner edge of the frame.

[0032] It should be noted that the number of six retaining blocks 201 provides sufficient support points for the lens 102 to ensure connection strength without excessively increasing the difficulty of production and assembly. The even distribution of the retaining blocks 201 ensures that the clamping force on each point of the lens 102 is consistent, preventing deformation or damage to the lens 102 due to uneven local force. Especially for rigid lenses, uniform force can effectively extend their service life. At the same time, the evenly distributed retaining blocks ensure that the width and depth of the mounting seam are consistent, ensuring uniform fit between the soft rubber mask 103 and the frame 101 and lens 102 after insertion, further improving the overall sealing performance of the diving mask.

[0033] In one embodiment of this application, the frame 101 is a rigid shell formed by injection molding.

[0034] It should be noted that the rigid shell possesses high strength and rigidity, providing stable structural support for the entire diving mask. During diving, the rigid frame is less prone to deformation under the influence of underwater pressure, water flow, and tension during wear, ensuring the relative positional stability of components such as the lens, strap, and soft rubber mask, thus guaranteeing the normal function of the diving mask. The rigid shell also exhibits strong shape stability, enabling assembly structures such as the annular step 301, the retaining block 201, and the connecting part 105 to maintain precise dimensions and positions.

[0035] In one embodiment of this application, both the lens strap 104 and the soft silicone mask 103 are solid silicone.

[0036] It should be noted that the elasticity of solid silicone allows the mask strap 104 to adaptively adjust its tightness according to head size, securing the diving mask firmly without causing marks due to excessive tightness. At the same time, its soft texture reduces friction with the scalp, maintaining comfort even during extended wear.

[0037] The flexibility of solid silicone allows it to closely conform to the subtle contours of facial skin, filling the gaps between the skin and the frame 101 and effectively preventing water from entering the lens. Solid silicone also possesses a certain degree of hardness, maintaining a stable shape after being embedded in the mounting seam between the lens 102 and the retaining block 201, preventing it from easily detaching due to external pressure. Simultaneously, its elasticity fills the tiny gaps in the mounting seam, enhancing the overall sealing and connection strength of the structure.

[0038] In one embodiment of this application, the lens 102 is formed by PC injection molding, and the thickness of the lens 102 is 2-5mm.

[0039] It should be noted that a thickness of 2mm or more ensures sufficient structural stability of the lens and reduces optical distortion caused by excessive thinness. PC material itself has high light transmittance; within a thickness range of 2-5mm, the refraction and scattering of light passing through the lens are at a reasonable level, ensuring users obtain a clear and realistic underwater view and avoiding the impact of improper thickness on observation.

[0040] Lenses that are too thin will have reduced impact resistance, making them more susceptible to damage from impacts and water pressure during diving. On the other hand, lenses that are too thick will increase the weight of the lens, putting extra strain on the frame and potentially increasing the overall weight of the diving mask, thus affecting wearing comfort. A thickness of 2-5mm allows for a balance between maintaining lens impact resistance and controlling overall weight, achieving a balance between strength and lightweight design.

[0041] In one embodiment of this application, the surface of the lens 102 is provided with an anti-fog coating.

[0042] It should be noted that fogging of lenses is a common problem in diving scenarios. When the user's exhaled breath comes into contact with the cool surface of the lens, the water vapor in the breath condenses into tiny water droplets, which adhere to the lens and form fog, resulting in blurred vision.

[0043] In one specific implementation, a silica nano-coating is used as the anti-fog coating. A silica nanofilm is formed on the surface of a PC lens using a sol-gel method. The surface of this nanofilm contains numerous hydroxyl groups, exhibiting strong hydrophilicity. The nanoscale porous structure can adsorb water vapor and diffuse it rapidly, achieving the anti-fog effect. Simultaneously, the silica coating has high hardness and good wear resistance, and its coefficient of thermal expansion is similar to that of the PC lens, making it less prone to peeling off under temperature changes and able to withstand long-term underwater environmental conditions.

[0044] In one embodiment of this application, the edge of the soft rubber mask 103 that contacts the face is arc-shaped, the edge thickness gradually decreases from the end connected to the frame 101 to the free end, and the inner side of the edge is provided with several tiny anti-slip textures.

[0045] It should be noted that the curved design allows for a larger and more even contact area between the edges and facial skin, avoiding the risk of leakage due to poor fit in certain areas. When diving, the soft rubber mask 103 needs to be pressed against the face to achieve a seal. The curved edges distribute the pressure over a larger contact area, preventing skin pressure or marks caused by excessive local pressure, making it more suitable for extended wear.

[0046] The thinner free end near the face makes the edge softer and more deformable, adapting to the subtle contours of the face and tightly wrapping around the fine lines of the skin, filling tiny gaps that traditional edges of uniform thickness cannot cover, significantly improving sealing performance. The thicker end connecting to the frame provides sufficient structural support for the edge, ensuring it doesn't deform excessively or flare outwards under stress, maintaining overall shape stability. The thinner free end provides a softer feel when in contact with the skin, reducing the foreign body sensation caused by material hardness; simultaneously, the thin edge design reduces friction between the edge and the skin, preventing skin irritation caused by friction when wearing or removing the glasses. The thicker design of the connecting end ensures the connection strength between the soft silicone mask 103 and the frame 101, preventing the edge from detaching from the mounting seam and ensuring structural reliability.

[0047] In one embodiment of this application, the lens strap 104 is provided with adjustment buckles at both ends, and the adjustment port is used to adjust the length of the lens strap 104.

[0048] It should be noted that the adjustment buckles allow users to precisely adjust the length of the mask strap according to their own head features, making the diving mask fit the individual's head better, reducing wobbling or pressure caused by size mismatch, and improving wearing comfort and stability. The adjustment buckles at both ends of the mask strap are reasonably designed, allowing users to quickly operate them with one or both hands during the wearing process without the need for tools, making them suitable for quick operation underwater or in emergency situations.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the embodiments of the present application.
