[0028] It should be further understood that the term "and / or" used in this specification and the appended claims refers to and includes any and all possible combinations of one or more of the associated listed items.

[0029] Please refer to Figures 1 to 5The present invention provides a convenient diving mask suitable for snorkeling, diving, or underwater cleaning by frogmen, facilitating underwater vision. The diving mask includes a frame 1, a lens body 2, a flexible lens cover 3, a breathing tube 4, a drainage assembly 5, and an air inlet 6.

[0030] Specifically, the flexible lens skin 3 and the lens body 2 are embedded in the frame 1 to form an inner space 9 in the lens, and the embedded part of the flexible lens skin 3 is between the lens body 2 and the frame 1. The breathing tube 4 is detachably connected to the top of the frame 1, and the breathing tube 4 is used to connect the inner space 9 in the lens with the external environment so that people can breathe. The peripheral part of the flexible lens skin 3 along the edge is used to fit the face to adapt to users with different face shapes, thereby improving the applicability of the diving goggles; at the same time, the flexible lens skin 3 has an abutment portion 34 on one side of the inner space 9 located on both sides of the nose, and the abutment portion 34 can separate the inner space 9 into a viewing area 92 and a breathing area 91. The connection between the bottom of the lens body 2 and the flexible lens skin 3 is respectively penetrated by an air inlet 32, which connects the viewing area 92 and the breathing area 91, and an air inlet part 6 is provided at the air inlet 32.

[0031] The breathing tube 4 connects the viewing area 92 with the external environment and also has a first air outlet channel 492 that communicates with the external environment. The flexible lens cover 3 has second air outlet channels 35 along both sides of the lens body 2, connecting the breathing area 91 with the first air outlet channel 492. When the user inhales, external air enters the viewing area 92 through the breathing tube 4 and then enters the breathing area 91. When the user exhales, exhaled carbon dioxide enters the first air outlet channel 492 through the second air outlet channels 35 and is then discharged to the external environment through the exhaust hole 41.

[0032] The user can breathe through the nose while diving or working underwater with the diving mask, making it easier to use. During use, external air enters the viewing area 92 through the breathing tube 4. Breathing through the nose increases the air pressure in the breathing area 91, causing the air inlet member 6 to elastically deform toward the breathing area 91, opening the air inlet hole 32. This allows air to flow from the viewing area 92 into the breathing area 91, thereby improving the user's breathing comfort. At the same time, water inevitably enters the viewing area 92 through the breathing tube 4. The air inlet member 6 and the air inlet hole 32 can also be used to drain water, allowing accumulated water in the viewing area 92 to flow into the breathing area 91 through the air inlet hole 32.

[0033] A drainage hole 31 is formed through the bottom of the breathing area 91, connecting it to the external environment. A drainage assembly 5 is located at this hole. When the user dives underwater and fully submerges the breathing tube 4, it automatically seals, sealing the internal space 9 and preventing water from entering the breathing tube 4. When the air pressure within the breathing area 91 reaches a certain level, the water in the breathing area 91 flows to the drainage hole 31 under the influence of the air pressure and is then discharged from the breathing area 91 to the external environment through the drainage assembly 5. This allows the diving mask to automatically drain accumulated water during use, preventing water from entering the eyes or affecting breathing, thus improving the convenience of drainage and user comfort.

[0034] In one embodiment, the breathing tube 4 includes a float 43, a sealing gasket 44, a second tube cover 45, an upper tube body 46, and a lower tube body 47. The upper tube body 46, the lower tube body 47, and the frame 1 are detachably connected. Specifically, the upper tube body 46 is provided with a ventilation chamber 461 to accommodate the float 43. The sealing gasket 44 is fixed to the connection between the second tube cover 45 and the upper tube body 46. The sealing gasket 44 defines a first ventilation port 441 and a second ventilation port 442. The breathing tube 4 also has an air inlet channel 491. The viewing area 92, the air inlet channel 491, the first ventilation port 441, the second ventilation port 442, and the ventilation chamber 461 are sequentially connected to the external environment. When the breathing tube 4 is submerged, the float 43 floats upward to block the second ventilation port 442, thereby sealing the internal space 9 of the scope from the internal space of the tube. Here, the first air outlet channel 492 and the air inlet channel 491 together constitute the internal space 49 of the tube.

[0035] Furthermore, sealing rings 48 are respectively provided at the connection points of the upper tube body 46, the lower tube body 47 and the frame 1 of the breathing tube 4 to improve the airtightness of the breathing tube 4 and at the same time improve the stability of the connection between the upper tube body 46, the lower tube body 47 and the frame 1.

[0036] In one embodiment, air inlet members 6 are located at the bottom of each side of the lens body 2, and the air inlet holes 32 on the flexible lens cover 3 correspond to the air inlet holes 32 on the lens body 2. The air inlet members 6 are elastic and fixedly mounted at the air inlet holes 32. The air inlet members 62 are inserted and positioned on one side of the breathing zone 91.

[0037] Under normal conditions, the sides of the air intake member 6 fit over the air intake hole 32, thereby sealing it. When the user breathes, external air enters the viewing area 92 through the breathing tube 4. Breathing through the user's nose increases the air pressure in the breathing area 91, causing the air intake member 6 to elastically deform toward the breathing area 91, opening the air intake hole 32. Air then flows from the viewing area 92 into the breathing area 91, providing fresh air for the user. Simultaneously, accumulated water in the viewing area 92, under the influence of air pressure, flows downward toward the air intake hole 32, then into the breathing area 91, and out through the drainage hole 31, further enhancing the convenience of draining water from the diving mask.

[0038] Please refer to Figure 4 In one embodiment, the top of the breathing tube 4 is provided with exhaust holes 41 on either side, connecting the first air outlet channel 492 with the external environment. An air inlet member 6 is secured to the side of the exhaust hole 41 facing away from the first air outlet channel 492. A first tube cover 42 is secured to the outside of the breathing tube 4, forming a deformation chamber between the first tube cover 42 and the breathing tube 4, allowing the air inlet member 6 to elastically deform. The operating principle of the air inlet member 6 will not be further described here. By providing the air inlet member 6 in the breathing tube 4, the user's exhaled carbon dioxide can be discharged, further improving the user's breathing comfort and the ease of use of the diving mask.

[0039] In one embodiment, the drainage assembly 5 includes a water barrier 51 and a fixing cover 52, which are sequentially fixed to the drainage hole 31. The water barrier 51 is elastic, and a deformation cavity is formed between the drainage hole 31 and the fixing cover 52, allowing the water barrier 51 to elastically deform. The fixing cover 52 further restrains the water barrier 51 within the deformation cavity, improving the installation stability of the water barrier 51. At the same time, the water barrier 51 is not exposed, making the diving mask more aesthetically pleasing.

[0040] Under normal conditions, the perimeter of the water barrier 51 fits over the drainage hole 31, thereby sealing the hole 31 and preventing water from the external environment from entering the mirror interior space 9. Under drainage conditions, when water in the breathing zone 91 flows downward to the drainage hole 31 under the action of air pressure, the perimeter of the water barrier 51, under the action of the water pressure, bends away from the breathing zone 91, thereby opening the drainage hole 31. The water in the breathing zone 91 then flows out of the external environment through the gap between the flexible mirror skin 3 and the water barrier 51.

[0041] In one embodiment, to enhance the waterproofing of the diving mask, a waterproof strip 36 made of flexible silicone is provided at the bottom edge of the breathing zone 91 for contact with the face. When the user wears the diving mask, the strip 36 abuts between the nose and upper lip, preventing water from entering the mask during diving, thus enhancing the user experience.

[0042] In one embodiment, the top of the frame 1 is provided with a connector 11 for connecting to the lower tube 47, and the top of the lens body 2 is provided with a connecting portion 21. The position of the connecting portion 21 corresponds to that of the connecting portion 11. When the diving mask is assembled, the connecting portion 21 is inserted into the connecting portion 11 to connect the space inside the tube with the space inside the lens 9, thereby improving the stability of the connection between the lens body 2 and the frame 1. Stoppers 22 are provided at intervals on the outer periphery of the lens body 2, and stopper holes 33 corresponding in shape and position to the stopper holes 22 are formed through the outer periphery of the flexible lens cover 3. When the flexible lens cover 3 is fitted over the lens body 2, the stopper parts 22 are inserted and stopped in the stopper holes 33, thereby improving the stability of the connection between the flexible lens cover 3 and the lens body 2.

[0043] Please refer to Figure 5 In one embodiment, the diving goggles further include a detachable lens 7 disposed within the viewing area 92. The detachable lens 7 comprises a lens 71 and an assembly 72. The lens 71 is adjustably mounted on the assembly 72, and the assembly 72 is detachably connected to the inner side of the lens body 2. The lens 71 can be a myopia lens 71, which can be replaced according to the user's myopia level, or it can be another functional lens. The lens material is flexible and not easily broken, and can be removed when no longer needed, thereby improving the applicability of the diving goggles.

[0044] In one specific embodiment, the lens 71 is provided with an adjustment slot 711, with a positioning piece 712 integrally formed therein. The assembly part 72 includes a fixedly connected suction cup 721 and an adjustment portion 722. The adjustment portion 722 extends through the adjustment slot 711, and one side of the adjustment portion 722 is provided with a positioning tooth 723 that engages with the positioning piece 712. The suction cup 721 is attached to the inner side of the lens body 2, allowing the lens 71 to be detachably connected to the lens body 2. The user can adjust the height of the lens 71 according to their usage. After the lens 71 is adjusted to an appropriate height, the positioning piece 712 engages between two adjacent positioning teeth 723 to fix the height of the lens 71, further enhancing the applicability of the detachable lens 7.

[0045] In one embodiment, the diving mask further includes a camera holder 8 detachably connected to the breathing tube 4. The camera holder 8 includes a mounting portion 82 and a fixing portion 81 that are fixedly connected. The fixing portion 81 is sleeved on an end of the lower tube 47 near the frame 1. The mounting portion 82 can fix the underwater camera with screws, thereby improving the convenience of using the diving mask.

[0046] The above description is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present application, and such modifications or substitutions should be included in the scope of protection of the present application. Therefore, the scope of protection of the present application should be based on the scope of protection of the claims.
