[0018] In the description of this utility model, it should be noted that, unless otherwise specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0019] See Figures 1 to 6 The diving mask 1 of the embodiment of the present invention includes a mask 1 and a frame 2, the mask 1 is arranged on the frame 2, the frame 2 is provided with a lens 3, the mask 1 is formed with a nasal cavity accommodating groove 11, and the outer wall of the nasal cavity accommodating groove 11 is provided with a supporting edge 12 on both sides, and a sealing edge 13 is also provided along the inner wall of the mask 1, and a partition 4 is provided between the sealing edge 13 and the nasal cavity accommodating groove 11. Strap brackets 5 are also provided on both sides of the frame 2, and the strap bracket 5 is provided with a roller assembly 6.

[0020] In the above embodiment, the diving mask 1 primarily consists of a mask 1 and a frame 2, with the mask 1 fixedly mounted on the frame 2. The frame 2 houses a lens 3 for viewing the underwater environment. The mask 1 is provided with a nasal cavity accommodating slot 11 to accommodate the wearer's nasal structure. The outer walls of the nasal cavity accommodating slot 11 are equipped with support ribs 12 on both sides to enhance wearer stability and comfort and to prevent slipping hands.

[0021] The inner wall of the mask 1 is provided with a sealing edge 13 along its edge, ensuring a tight fit against the face and preventing moisture from seeping in. A certain gap exists between the sealing edge 13 and the nasal cavity receiving groove 11. During initial wear, gently squeezing the mask 1 allows air between the mask 1 and the face to escape smoothly through this gap, thus ensuring an initial seal.

[0022] When a diver enters the water, the mask 1 may become loose due to water pressure and current, allowing water and air to enter. In this case, the mask 1 is squeezed firmly to drain the water. Then, by pressing against the support edge 12 and squeezing the nasal cavity 11, the accumulated water and air are forced out of the nasal cavity 11. Because the partition 4 is close to the nasal cavity 11, the water and air flow smoothly out through the partition 4, achieving effective drainage and exhaust, ensuring respiratory function.

[0023] Frame 2 is flanked by strap brackets 5, each equipped with a roller assembly 6. The strap passes over the roller assembly 6 and is secured by a fixing element. Multiple evenly spaced blocks abut against the fixing element, creating a stable, secure fit. When one end of the strap is pulled, the roller assembly 6 ensures smooth, non-stuck sliding. As the strap is tightened, the fixing blocks abut against the forward-facing blocks, further tightening the mask 1 and effectively preventing moisture from entering. This design improves drainage and airflow during diving.

[0024] See Figures 1 to 6 In another embodiment, the support edge 12 is bent and arranged on the nasal cavity receiving groove 11, and the curved shape of the support edge 12 matches the fingertip.

[0025] In the above embodiment, the support edge 12 is designed to be curved and positioned on either side of the outer wall of the nasal cavity receiving slot 11. This curve matches the shape of the fingertips, allowing the wearer to easily press against the support edge 12 and apply the necessary pressure when needed. The curved support edge 12 allows the wearer to more effectively utilize the strength of their fingers, thereby achieving a secure grip on the mask 1. When water or air enters the mask 1, the wearer can press against the curved support edge 12 with their fingertips and squeeze the nasal cavity receiving slot 11, squeezing the water and air out of the nasal cavity receiving slot 11, ensuring a tight seal and wearer comfort.

[0026] See Figures 1 to 6 In another embodiment, the roller assembly 6 includes a rotating rod 61 and at least one rotating wheel 62. The strap bracket 5 is provided with rotating holes opposite to each other on the upper and lower sides. The two ends of the rotating rod 61 are arranged in the rotating holes, and the rotating wheel 62 is fixedly provided on the rotating rod 61.

[0027] In the above embodiment, opposing rotation holes are provided on the upper and lower sides of the strap bracket 5, providing a location for the mounting of the rotating rod 61. The ends of the rotating rod 61 are precisely positioned in these two rotation holes, ensuring stable fixation. The rotating wheel 62 is fixedly mounted on the rotating rod 61 and rotates as the rotating rod 61 rotates. When the strap passes over the rotating wheel 62, the rolling of the rotating wheel 62 reduces friction between the strap and the bracket, allowing the strap to slide easily on the roller assembly 6, achieving smooth adjustment and fixation underwater and eliminating the feeling of catching when tightening the strap.

[0028] See Figures 1 to 6 In another embodiment, the sealing edge 13 is initially inclined inwardly at an angle of 60° to 70°.

[0029] In the above embodiment, the fit between the mask 1 and the face is optimized. When the wearer places the mask 1 against their face, the inwardly angled sealing edge 13 more effectively adapts to the facial contours, creating a tighter seal. This angle ensures that the sealing edge 13 provides sufficient pressure to maintain a seal without causing excessive pressure on the wearer. This structural principle not only improves the sealing performance of the mask 1 but also ensures wearing comfort.

[0030] See Figures 1 to 6 In another embodiment, a support block 7 is extended downward from the middle of the top end of the frame 2 where it is connected to the mask 1 .

[0031] In the above embodiment, the primary function of support block 7 is to support the wearer's forehead, ensuring that it does not directly contact the lens 3 when the mask 1 is worn. This design helps prevent the pressure caused by contact between the forehead and the lens 3, while also helping to maintain an appropriate distance between the lens 3 and the eyes, ensuring a clear and comfortable field of vision. The presence of support block 7 also enhances the stability of the mask 1, making it more secure during wear and less likely to slip or shift, thereby improving the safety and efficiency of diving operations.

[0032] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technician familiar with this profession can make some changes or modifications to equivalent embodiments of the technical content disclosed above without departing from the scope of the technical solution of the present invention. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
