Description

Technical Field

[0001] This application relates to the field of diving equipment technology, and in particular to a full-face diving mask. Background Technology

[0002] With the increasing popularity of underwater recreational activities, snorkeling has become a widely enjoyed underwater sport. When snorkeling, divers use a diving mask to keep their head underwater while observing and breathing. Traditional diving masks for snorkeling are mainly divided into two types based on breathing pattern: mouthpiece breathing and full-face mask breathing. A mouthpiece mask only covers the goggles and nose, leaving the mouth exposed to bite down on a separate tube for free breathing during the dive. A full-face mask completely covers the face, with the tube integrated into the mask; breathing is done using the tube attached to the top or side of the mask. Because the mask fits snugly against the user's face and has an independent structural space, the user can breathe freely within that space.

[0003] In existing full-face diving masks, since both inhalation and exhalation occur through the same tube during breathing, gas cannot be separated. This can cause a sharp increase in carbon dioxide concentration inside the mask, leading to insufficient oxygen supply when the user re-inhales it, which in turn causes discomfort. Utility Model Content

[0031] 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.

[0032] The inventors discovered through analysis of existing technologies that current diving masks do not have a connecting cavity. After the gas enters the mask for human breathing, the carbon dioxide exhaled by the human mixes with the gas in the mask and is then expelled through the breathing tube or exhaust valve. This causes the carbon dioxide in the mask to increase, leading to oxygen deficiency and a poor user experience.

[0033] Reference Figure 1-5 The diagram shows a structural schematic of a full diving mask provided in this application.

[0034] A full-face diving mask includes a frame 1 and a breathing tube 2 disposed on the top of the frame 1. The frame 1 has a first soft cover 3 for covering the face and a second soft cover 4 for covering the mouth and nose area. The first soft cover 3 has a connecting cavity 5. The connecting cavity 5 includes a long cavity 51 and a short cavity 52. ​​One end of the long cavity 51 is connected to the breathing tube 2 and the other end is connected to the second soft cover 4. One end of the short cavity 52 is connected to the breathing tube 2 and the other end is connected to the first soft cover 3.

[0035] In the embodiments of this application, addressing the problem in existing diving masks where inhalation and exhalation occur through the same tubing, making it impossible to separate inhaled and exhaled gases, this application provides a solution by adding a connecting cavity 5 and a separate breathing tube 2. Specifically, it includes a frame 1 and a breathing tube 2 disposed at the top of the frame 1. The frame 1 contains a first soft cover 3 for covering the face and a second soft cover 4 for covering the mouth and nose area. The first soft cover 3 contains a connecting cavity 5; the connecting cavity 5 includes a long cavity 51 and a short cavity 52; one end of the long cavity 51 communicates with the breathing tube 2, and the other end communicates with the second soft cover 4; one end of the short cavity 52 communicates with the breathing tube 2, and the other end communicates with the first soft cover 3. This device effectively solves the problem of existing full-face diving masks failing to effectively and quickly expel the increased carbon dioxide concentration during breathing, improving safety and user experience. Simultaneously, the above-mentioned full-face diving mask has good sealing and versatility, is not easily leaked, and is suitable for more face shapes.

[0036] The following will further describe a full-face diving mask in this exemplary embodiment.

[0037] In one embodiment of this application, the breathing tube 2 includes an air inlet channel 21 and an exhaust channel 22; the air inlet channel 21 is connected to the short cavity 52; the exhaust channel is connected to the long cavity 51. The long cavity 51 and the short cavity 52 are integrally formed and connected; a valve plate 53 is provided at one end of the long cavity 51 near the breathing tube 2.

[0038] It should be noted that the end of the breathing tube 2 away from the frame 1 is provided with a tube cap 23, and the end of the air inlet channel 21 of the breathing tube 2 away from the frame 1 is provided with a wave deflector 24 and an air inlet 25.

[0039] It should be noted that the breathing tube 2 is L-shaped, with the shorter end of the tube connected to the top of the first soft mask 3, and the longer end of the tube having a cap 23. The cap 23 and the breathing tube 2 are detachably connected.

[0040] In one embodiment of this application, the second soft mask 4 is provided with air inlet valves 41 on both sides and an exhaust valve 42 at the bottom. The first soft mask 3 and the second soft mask 4 are integrally formed and connected, with the second soft mask 4 disposed inside the first soft mask 3. When the full-face mask is worn, the first soft mask 3 and the second soft mask 4 are not connected. When the air inlet valve 41 is opened, the gas inside the first soft mask 3 enters the second soft mask 4 through the air inlet valve 41. At this time, the exhaled carbon dioxide is discharged through the exhaust channel of the breathing tube 2 via the elongated cavity 51, and is also directly discharged through the exhaust valve 42 at the bottom of the second soft mask 4. In this way, carbon dioxide will not enter the first soft mask 3, effectively isolating the exhaled gas from the input gas, more effectively expelling the exhaled gas, improving the purity of the gas inside the first soft mask 3, and solving the problem of oxygen deficiency caused by gas mixing in existing diving masks. For details on the gas flow direction, please refer to [reference needed]. Figures 7-9 ,in, Figure 7 It indicates the direction of air inlet and outlet in the connecting cavity. Figure 8 It is a diagram indicating the air intake direction of the entire mask and breathing tube. Figure 9 It is an indicator diagram showing the direction of airflow from the entire mask and breathing tube.

[0041] It should be noted that both the first soft cover 3 and the second soft cover 4 are made of liquid silicone. The edge of the first soft cover 3 is an elastic skirt. This elastic skirt can improve the universality of different users' faces, and also improve the fit between the face and the mask, thus increasing the sealing performance.

[0042] In one embodiment of this application, the diving mask further includes an elastic headband. Buckles 31 are provided on both sides of the first soft cover 3 for inserting the elastic headband.

[0043] In one embodiment of this application, the frame 1 includes a frame 11 and a lens 12 detachably connected to the frame 11.
