Description

Technical Field

[0001] This utility model relates to the field of snorkeling auxiliary equipment technology, and in particular to a snorkeling mask. Background Technology

[0002] A snorkeling mask is a diving device that integrates a snorkel and a mask, providing divers with a more comfortable and safer underwater experience.

[0003] Common snorkeling masks cover the entire face, such as full-face snorkeling masks, which extend from the eyebrows to the cheeks and chin, including the eye, nose, and mouth areas. This allows for natural breathing through the nose and mouth without needing to put the snorkel in the mouth. The snorkel is usually located at the top of the mask, connecting the inside of the snorkeling mask to the outside fluid. This allows outside air to enter the snorkeling mask for the user to breathe, while also allowing the user to expel carbon dioxide produced by breathing through the snorkel, enabling the user to achieve breathing circulation underwater without holding their breath.

[0004] However, full-face snorkeling masks cover the entire face, making the product larger and relatively heavier, which reduces the user's wearing experience. At the same time, the total space inside a full-face snorkeling mask that holds fluids (such as air) is larger, and it can hold more carbon dioxide / oxygen. When a user is underwater for a period of time, because the inside of the full-face snorkeling mask is in a sealed state, the carbon dioxide concentration inside the mask will increase and the total amount of carbon dioxide will be larger. Users are more likely to experience difficulty breathing or a feeling of not being able to breathe, which reduces the user's snorkeling experience.

[0005] Therefore, how to design the shape and structure of snorkeling masks to reduce the mask's volume and internal air capacity in order to improve the user's snorkeling experience has become an urgent technical problem to be solved. Utility Model Content

[0006] The main purpose of this utility model is to provide a snorkeling mask that aims to solve the technical problem of how to reduce the mask's volume and internal air capacity in order to improve the user's snorkeling experience.

[0007] To achieve the above objectives, this utility model provides a snorkeling mask, including a mask body and a breathing tube. The interior of the breathing tube is in fluid communication with the interior of the mask body. The mask body includes a breathing section and an observation section, which are separated and separated by a gap to expose the skin of the cheekbone. The breathing tube is connected to the breathing section and is bent and positioned behind the neck to allow direct fluid communication between the breathing section and the outside.

[0008] Optionally, the mask body includes a support frame and a flexible mask;

[0009] The flexible mask includes an observation chamber and a breathing chamber that are connected to each other. The observation chamber covers the periphery of the eyes, and the breathing chamber covers the periphery of the mouth and nose, while the cheekbone area is exposed.

[0010] The support frame includes an eye frame, a nose bridge support, and a mouth and nose frame. The eye frame and the mouth and nose frame are connected by the nose bridge support, and there is a gap between the eye frame and the mouth and nose frame.

[0011] Optionally, the front end of the flexible mask is fixed to the back of the support frame, and the back of the flexible mask is in contact with the skin of the face.

[0012] Optionally, the front end of the flexible mask is fixed to the back of the support frame as follows: the eye frame is engaged with the observation cavity, and the nose bridge support and the mouth and nose frame are engaged with the breathing cavity respectively.

[0013] Optionally, the eye frame is engaged with the observation cavity as follows: the front end of the observation cavity includes an eye connection opening, the mask body also includes an eye support frame, the eye support frame is fitted onto the eye connection opening, and the eye frame is engaged with the eye support frame.

[0014] Optionally, the nasal bridge support and the mouth and nose frame are respectively engaged with the breathing cavity as follows: the front end of the breathing cavity includes a mouth connection opening, the front edge of the mouth connection opening extends inward with a second engaging protrusion, and the outer peripheral edge of the mouth and nose frame is provided with a third engaging protrusion, the second engaging protrusion engaging with the third engaging protrusion.

[0015] Optionally, the mask body further includes a mouth opening frame, which is snapped into the mouth connection opening;

[0016] The outer peripheral edge of the opening frame is provided with a second snap-fit ​​ring groove, and the second snap-fit ​​protrusion snaps into the second snap-fit ​​ring groove so that the opening frame snaps into the opening.

[0017] Optionally, the breathing tube is connected to the breathing cavity, and one end of the breathing tube is snapped into the support frame.

[0018] Optionally, the breathing tube includes a breathing tube connector, and the mouth and nose frame is provided with a breathing tube plug, which is snapped into the breathing tube connector.

[0019] Optionally, the breathing tube also includes a tubular body and a buoyancy control valve, with the buoyancy control valve located at the other end of the breathing tube; one end of the tubular body is connected to the buoyancy control valve, and the other end of the tubular body is connected to the breathing tube connector.

[0020] The connection between the breathing tube connector and the tubular body is bent, and the bending angle formed by the extension line of the breathing tube connector and the extension line of the tubular body is α, where 100°≤α≤120°.

[0021] In the technical solution provided by this utility model, firstly, by leaving a gap between the breathing part and the observation part of the mask body, that is, by opening the first cheekbone adaptation incision on the left and right sides of the flexible mask, the first cheekbone adaptation incision is located in the area formed by the lower part of the observation cavity and the upper part of the breathing cavity, and a gap is left in the area formed by the lower part of the eye frame and the upper part of the mouth and nose frame of the support frame. While ensuring the waterproof and airtight performance of the snorkeling mask and the function of breathing air, the area covered by the user's face is reduced, the overall weight of the snorkeling mask is reduced, leaving only the necessary coverage area and breathing part, so that the user's skin has the function of sensing and can directly contact the water, thereby improving the user's experience.

[0022] Secondly, by creating a gap between the breathing section and the observation section, the capacity of the air bladder in the mask body 1 is reduced. The reduced capacity of the air bladder makes it more difficult for the user to breathe if the breathing tube is set up with separate exhaust and exhalation channels. However, the breathing tube of this utility model is connected to the breathing section, which is the part that stores air, so that the breathing tube has bidirectional fluid communication with the outside. The user can perform inhalation and exhalation operations through the same breathing tube, without having to use a separate dual-channel breathing tube for inhalation and exhalation when snorkeling. This makes breathing easier for the user when snorkeling and improves the user experience.

[0023] Third, the snorkel is designed to wrap around the neck at the back. The bending angle formed by the extension line of the snorkel connector and the extension line of the tubular body is about 110°. This bending angle is a biomimetic bending angle that conforms to ergonomics. This design overturns the traditional front-mounted snorkel design, extending the channel to the back of the neck and optimizing the breathing path of the snorkel mask through ergonomics. Furthermore, the air bladder of the mask body is relatively flat and has smooth lines, and the curved shape of the snorkel is also smooth. This reduces the ineffective gas exchange space inside the snorkel mask, reduces airflow dead zones, and accelerates the gas exchange rate. Carbon dioxide does not easily accumulate excessively in the air bladder of the mask body, making it easier for users to breathe and improving the user experience when snorkeling.

[0053] Example 1

[0054] To achieve the above objectives, this utility model provides a snorkeling mask, please refer to the attached document. Figures 1-24 , including Figure 1This is a schematic diagram of the structure of a snorkeling mask in one or more embodiments. Specifically, it includes a mask body 1 and a breathing tube 2. The inside of the breathing tube 2 is in fluid communication with the inside of the mask body 1. The mask body 1 includes a breathing section 01 and an observation section 02, which are separated and have a gap between them to allow the skin of the cheekbone to be exposed. The breathing tube 2 is connected to the breathing section 01 and is bent and positioned behind the neck to allow the breathing section 01 to be in direct fluid communication with the outside.

[0055] Among them, breathing section 01 is the part where a person breathes underwater through a snorkeling mask, and observation section 02 is the part where a person observes underwater through a snorkeling mask.

[0056] When the upper end of the breathing tube 2 is above the water surface, the breathing tube connects to the outside world, allowing gas exchange to take place inside the mask body 1. When the upper end of the breathing tube 2 is below the water surface, the upper end of the breathing tube 2 is closed to prevent the entry of external fluids, so that water will not enter the mask body 1 and the air inside the mask body 1 will not be lost. By controlling the rise and fall of the breathing tube 2, the user can exchange gases underwater.

[0057] When a person exhales and inhales, the passage for exhaling gas and the passage for inhaling gas share the same breathing tube 2, which is called "shared breathing tube".

[0058] In this embodiment, the gap between the breathing section 01 and the observation section 02 reduces the capacity of the air bladder in the mask body 1. This reduced capacity would make breathing difficult for the user if the breathing tube 2 were divided into separate exhaust and exhalation channels. However, the breathing tube 2 of this invention connects to the breathing section 01, which stores air, allowing the breathing tube 2 to have bidirectional fluid communication with the outside. The user can perform inhalation and exhalation through the same breathing tube 2, eliminating the need for separate inhalation and exhalation channels during snorkeling. This simplifies breathing and improves the user experience during snorkeling.

[0059] Optionally, the mask body 1 includes a support frame 11 and a flexible mask 12;

[0060] The flexible mask 12 includes an observation chamber 121 and a breathing chamber 122 that are connected to each other. The observation chamber 121 covers the periphery of the eyes, and the breathing chamber 122 covers the periphery of the mouth and nose, while the cheekbone area is exposed.

[0061] The support frame 11 includes an eye frame 111, a nose bridge support 112, and a mouth and nose frame 113. The eye frame 111 and the mouth and nose frame 113 are connected by the nose bridge support 112, and there are a large number of gaps between the eye frame 111 and the mouth and nose frame 113.

[0062] The support frame 11 only has an eye frame 111, a nose bridge support 112, and a mouth and nose frame 113. Compared with a full-face snorkeling mask, it removes the mask coverage area of ​​the cheeks and forehead on both sides, making the overall weight of the snorkeling mask lower. Users will not feel very heavy when snorkeling or carrying it, further improving the user experience.

[0063] The support frame 11 is a rigid, one-piece support that can be made of common rigid materials such as PC, PE, PS, and PP. This ensures that the support frame 11 has a certain ability to resist water pressure and can also support the flexible mask 12, making the flexible mask 12 fit the user's facial contours better.

[0064] Specifically, the breathing chamber 122 can accommodate a person's nose and mouth at the same time, and the observation chamber 121 can accommodate a person's eyes and the skin around the eyes.

[0065] Specifically, the flexible mask 12 has a first zygomatic bone adaptation incision 123 on the left and right sides of the middle part facing inward. The first zygomatic bone adaptation incision 123 is located between the breathing chamber 122 and the observation chamber 121. The first zygomatic bone adaptation incision 123 is used to fit tightly against the skin other than the zygomatic bone. The edge of the first zygomatic bone adaptation incision 123 is provided with an incision isolation wall 1231 for sealing and waterproofing. The incision isolation wall 1231 can fit tightly against the skin other than the user's zygomatic bone, so that the user's zygomatic bone skin is exposed and directly in contact with the outside world.

[0066] Optionally, a chamber partition 124 is provided at the upper rear end of the flexible mask 12. The chamber partition 124 is located at the connection between the observation chamber 121 and the breathing chamber 122. The chamber partition 124 can open the nose part of the breathing chamber 122 to leave a certain space to accommodate the user's nose.

[0067] Specifically, the chamber partition 124 is arranged in an inverted V shape; the height of the chamber partition 124 gradually decreases from top to bottom, further conforming to the contour of the human nose and the skin of the nose, and further improving the user experience.

[0068] Optionally, the upper part of the front end of the breathing chamber 122 is provided with a nasal fitting convex surface, and the back of the nasal fitting convex surface is the nasal fitting cavity, which conforms to the contour of the user's nose; the left and right sides of the nasal fitting convex surface are provided with several flat pressure protrusions 1226, which are used by the user to press the flat pressure protrusions during underwater snorkeling to balance the pressure between the nose and ears; since the surface of the underwater snorkeling mask is relatively slippery, the flat pressure protrusions 1226 can increase the friction between the snorkeling mask and the user's fingers, making it easier for the user's fingers to press the nose through the snorkeling mask, thereby achieving a state of ear and nose balance.

[0069] Optionally, the front end of the flexible mask 12 is fixed to the back of the support frame 11, and the back of the flexible mask 12 conforms to the skin of the face.

[0074] Optionally, the inner wall of the first snap-fit ​​protrusion 1212 extends inward to the lens fixing stage 1214, and the lens 3 is fixed on the lens fixing stage 1214.

[0075] The lens retainer 1112 extends inward from the side of the eye frame 111 and is pressed onto the lens 3.

[0076] Optionally, a forehead male stop 1216 is provided at the upper part of the front end of the observation cavity 121, and the support frame 11 includes a forehead female stop 114. The forehead female stop 114 is located at the upper part of the eye frame 111, and the forehead female stop 114 is inserted into the forehead male stop 1216 so that the upper part of the eye frame 111 of the support frame 114 is fixed to the upper part of the front end of the observation cavity 121. Specifically, the forehead male stop 1216 can be filled with adhesive so that the forehead female stop 114 is fixed at the forehead male stop 1216, further improving the sealing performance of the snorkeling mask. While reducing the overall volume and weight of the snorkeling mask, the sealing performance of the inside of the snorkeling mask is ensured, further improving the user experience.

[0077] Optionally, the nasal bridge support 112 and the oral and nasal frame 113 are respectively engaged with the breathing cavity 122 as follows: the front end of the breathing cavity 122 includes an oral connection opening 1221, the front edge of the oral connection opening 1221 extends inward with a second engaging protrusion 1222, and the outer peripheral edge of the oral and nasal frame 113 is provided with a third engaging protrusion 1131, and the second engaging protrusion 1222 engages with the third engaging protrusion 1131.

[0078] Optionally, the outer periphery of the second snap-fit ​​protrusion 1222 is provided with a plurality of second snap-fit ​​grooves 12221, and the third snap-fit ​​protrusion 1131 is provided with a plurality of first snap-fit ​​protrusions 11331. The first snap-fit ​​protrusions 11331 are inserted into the second snap-fit ​​grooves 12221 to improve the connection and fixation between the nose bridge support 112 and the mouth and nose frame 113, and further improve the sealing and waterproof performance of the snorkeling mask.

[0079] The shape, quantity, and position of the first snap-fit ​​protrusion 11331 are adapted to the second snap-fit ​​groove 12221.

[0080] Optionally, the mouth and nose frame 113 protrudes forward to form a mouth support baffle 1132, and the mouth support baffle 1132 extends backward to the breathing chamber connecting wall 1133; a third snap-fit ​​ring groove 1223 is provided on the outer periphery of the front end of the mouth connecting opening 1221, and the breathing chamber connecting wall 1133 is fitted into the third snap-fit ​​ring groove 1223.

[0081] Optionally, a one-way drain valve 1135 is provided at the front end of the mouth and nose frame 113.

[0082] Optionally, the lower end of the mouth and nose frame 113 is provided with a pin holder 1136 for fixing an external shooting device, which can be used to connect an external underwater camera.

[0083] Optionally, the mask body 1 also includes a mouth opening frame 14, which is snapped into the mouth connection opening 1221.

[0084] Specifically, the mouth opening frame 14 is engaged with the mouth connection opening 1221 as follows: a second engaging ring groove 141 is provided on the outer peripheral edge of the mouth opening frame 14, and a second engaging protrusion 1222 is engaged with the second engaging ring groove 141, so that the mouth opening frame 14 is engaged with the mouth connection opening 1221.

[0085] Specifically, the front and rear walls of the second snap-fit ​​groove 141 are located at the front and rear ends of the second snap-fit ​​protrusion 1222, respectively. This means that the second snap-fit ​​groove 141 "clamps" the second snap-fit ​​protrusion 1222. Adhesive can be filled into the second snap-fit ​​groove 141 to further fix the second snap-fit ​​protrusion 1222 within the groove, thereby further improving the sealing performance of the snorkeling mask. At the same time, the mouth opening frame 14 supports the opening 1221 through the second snap-fit ​​groove 141, making the mouth opening 1221 less prone to deformation. When the user is snorkeling, the snorkeling mask still maintains a certain shape and will not deform or shift due to water pressure or external forces, further improving the sealing performance of the snorkeling mask and enhancing the user experience.

[0086] In this embodiment, a notch is provided at the upper part of the mouth opening frame 14, and the bottom of the notch is a bridging beam 142.

[0092] Optionally, the breathing tube 2 is connected to the breathing chamber 122, and one end of the breathing tube 2 is snapped into the support frame 11.

[0093] Optionally, the breathing tube 2 includes a breathing tube connector 21, and the mouth and nose frame 113 is provided with a breathing tube plug 1134, which is snapped into the breathing tube connector 21.

[0094] Optionally, the breathing tube plug 1134 is hollow, one end of the breathing tube plug 1134 is connected to the breathing tube connector 21, the breathing tube plug 1134 is provided with a plug through hole 11341, the breathing chamber 122 is provided with a breathing through hole 1225, and the breathing through hole 1225 is connected to the plug through hole 11341.

[0095] Optionally, the inner wall of the breathing tube connector 21 is provided with a plurality of first sealing rings 211, and a first sealing groove 212 is formed between adjacent first sealing rings 211;

[0096] The outer wall of the breathing tube plug 1134 is provided with a plurality of second sealing rings 11342, and a second sealing groove 11343 is formed between adjacent second sealing rings 11342.

[0097] At least one first sealing ring 211 is engaged in a second sealing groove 11343, or at least one second sealing ring 11342 is engaged in a first sealing groove 212.

[0098] Optionally, the snorkel plug 1134 is located on at least one side of the mouth and nose frame 113. The number of snorkel plugs 1134 can be one or two. When there is one snorkel plug 1134, it is located on the left or right side of the mouth and nose frame 113, so that the snorkel 2 connected to the snorkel plug 1134 can be placed around the neck and positioned behind the neck. When there are two snorkel plugs 1134, the two snorkel plugs 1134 can be located on the left and right sides of the mouth and nose frame 113 respectively. Correspondingly, the number of snorkel 2 should also be the same as the number of snorkel plugs 1134, which is two, so that the snorkel 2 connected to the snorkel plug 1134 can be placed around the neck and positioned behind the neck, with the channel extending to the back of the neck. This optimizes the breathing path of the snorkeling mask using ergonomics and improves the efficiency of ventilation.

[0099] Optionally, the breathing tube 2 also includes a tubular body 22 and a buoyancy control valve 23, with the buoyancy control valve 23 located at the other end of the breathing tube 2; one end of the tubular body 22 is connected to the buoyancy control valve 23, and the other end of the tubular body 22 is connected to the breathing tube connector 21.

[0100] The connection between the snorkel connector 21 and the tubular body 22 is bent. The bending angle formed by the extension line of the snorkel connector 21 and the extension line of the tubular body 22 is α, where 100°≤α≤120°. When 100°≤α≤120°, the snorkel is positioned behind the neck. Preferably, α is 110°, and the bending angle formed by the extension line of the snorkel connector and the extension line of the tubular body 22 is approximately 110°. This bending angle is an ergonomic, biomimetic bending angle, which differs from the traditional front-mounted snorkel 2. It extends the air intake and exhaust channels to the back of the neck, optimizing the breathing path of the snorkeling mask through ergonomics. Furthermore, the airbag shape of the mask body 1 is relatively flat and has smooth lines, and the curved shape of the snorkel is smooth, thereby reducing the ineffective gas exchange space inside the snorkeling mask, reducing airflow dead zones, accelerating the gas exchange rate, and preventing excessive carbon dioxide accumulation in the airbag of the mask body 1. This makes it easier for the user to breathe and improves the user experience during snorkeling.

[0101] Preferably, the snorkel 2 is flexible, at least the tubular body 22 and the snorkel connector 21 are flexible, or the entire snorkel 2 can be flexible; optionally, the snorkel 2 is a flexible tube with a Shore hardness of 80, which can be integrally molded from flexible materials such as silicone, polyurethane (PU), thermoplastic elastomer (TPE), etc. It has both flexibility, which makes the snorkel foldable and easy to store, and a certain degree of rigidity, so that it will not easily deform during underwater snorkeling and affect the airflow. At the same time, the user can easily restore the snorkel 2 from the folded state to the upright state for use.

[0102] The flexible design makes the snorkel 2 easy for users to store and fold. Before use, the snorkel can return to its shape and will not deform when snorkeling underwater, making it convenient to use and carry.

[0103] There are two ways to set the breathing tube in a full-face snorkeling mask. One is to set the breathing tube at the top of the snorkeling mask. In this case, the face has to bear the weight of the exhaled air and the entire mask, which reduces the user's comfort. At the same time, because the breathing tube needs to go from the mouth and nose to the exhaust tube at the top for air exchange, the air inhalation and exhalation path is longer, requiring more effort to breathe. Compared with the separate mouthpiece breathing tube of this snorkeling mask, the advantages of this invention are that the mask body is set according to the contour of the face and human body, resulting in a better fit. The cheeks and eyes are not affected or fogged by exhaled air. The weight of the snorkeling mask is reduced, and the user's wearing experience is better. Secondly, the breathing tube is set at the bottom of the snorkeling mask. The breathing tubes are positioned on the left and right sides of the breathing chamber, with a rear-mounted neck loop design, allowing for simultaneous breathing and exhalation. This shortens the path for air inhalation and exhalation, making breathing easier for the user. Because the mask is designed based on the facial contours, the breathing chamber of the snorkeling mask stores less air and accumulates less carbon dioxide, making breathing smoother and easier, thus improving the user experience. Furthermore, due to the smaller air volume in the breathing chamber, the breathing tubes are located on the left and right sides of the lower breathing chamber of the snorkeling mask. A one-way valve is not required between the breathing tubes and the breathing chamber, allowing the user to exhale and exhale directly through the breathing tubes, making breathing easier and enhancing the user experience.
