Description

Technical Field

[0001] The invention relates to the technical field of snorkeling auxiliary equipment, and in particular to a snorkeling mask. Background Art

[0002] A snorkeling mask is a diving equipment that integrates a breathing tube and a mask design, which provides divers with a more comfortable and safer underwater experience.

[0003] Common snorkeling masks cover the entire face, such as a full-face snorkeling mask, which covers the entire face from eyebrows to cheeks to chin, including the eye, nose, and mouth areas, allowing natural breathing through the nose and mouth without the need to hold a breathing tube in the mouth; the breathing tube is usually arranged on the top of the mask, and the breathing tube connects the inside of the snorkeling mask and the external fluid, allowing external air to enter the snorkeling mask for the user to breathe, and at the same time allowing the carbon dioxide generated by the user's breathing to be discharged to the outside through the breathing tube, so that the user can achieve breathing circulation underwater without holding his breath.

[0004] However, a full-face snorkeling mask covers the entire face, which makes the product larger and relatively heavy, reducing the user's wearing experience; at the same time, the total space inside the full-face snorkeling mask for containing fluid (such as air) is larger, and the amount of carbon dioxide / oxygen contained is greater. After the user dives underwater for a period of time, since the interior 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 is large, the user is prone to feel unable to breathe or having difficulty breathing, reducing the user's snorkeling experience.

[0005] Therefore, how to set the shape structure of the snorkeling mask to reduce the volume of the mask and the internal air capacity to improve the user's snorkeling experience has become a technical problem that needs to be solved urgently. Summary of the invention

[0006] The main purpose of the present invention is to provide a snorkeling mask, aiming to solve the technical problem of how to reduce the volume of the mask and the internal air capacity to improve the user's snorkeling experience.

[0007] To achieve the above-mentioned purpose, the present invention provides a snorkeling mask, comprising a mask body and a breathing tube, the interior of the breathing tube is fluidically connected to the interior of the mask body, the mask body comprises a breathing part and an observation part, the breathing part and the observation part are separated, and a gap is provided between the breathing part and the observation part to expose the cheekbone skin of a person; the breathing tube is connected to the breathing part, and the breathing tube is bent and arranged around the neck to enable the breathing part to be directly fluidically connected to the outside world.

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

[0009] The flexible mask includes an observation cavity and a breathing cavity connected to each other, wherein the observation cavity covers the periphery of the eyes, and the breathing cavity covers the periphery of the mouth and nose, with the cheekbones of the person being exposed;

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

[0011] Optionally, the front end of the flexible mask is fixed to the back side of the support frame, and the back side of the flexible mask fits the human facial skin.

[0012] Optionally, the front end of the flexible mask is fixed to the back side of the support frame such that: the eye frame is clamped to the observation cavity, and the nose bridge support part and the mouth and nose frame are clamped to the breathing cavity respectively.

[0013] Optionally, the eye frame is clamped to the observation cavity: the front end of the observation cavity includes an eye connecting opening, the mask body also includes an eye opening frame, the eye opening frame is sleeved on the eye connecting opening, and the eye frame is clamped to the eye opening frame.

[0014] Optionally, the nose bridge support portion and the mouth and nose frame are respectively clamped to the breathing cavity: the front end of the breathing cavity includes a mouth connecting opening, the front end edge of the mouth connecting opening extends inwardly with a second clamping protrusion, the outer peripheral edge of the mouth and nose frame is provided with a third clamping protrusion, and the second clamping protrusion is clamped to the third clamping protrusion.

[0015] Optionally, the mask body further comprises a mouth opening frame, and the mouth opening frame is snap-fitted into the mouth connection opening;

[0016] The outer peripheral edge of the mouth opening frame is provided with a second snap ring groove, and the second snap protrusion is snapped at the second snap ring groove, so that the mouth opening frame is snapped at the mouth connection opening.

[0017] Optionally, the breathing tube is connected to the breathing cavity, and one end of the breathing tube is clamped to 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, and the breathing tube plug is clamped to the breathing tube connector.

[0019] Optionally, the breathing tube further comprises a tubular body and a buoyancy control valve, wherein the buoyancy control valve is arranged 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 joint;

[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, 100°≤α≤120°;

[0021] In the technical solution provided by the present invention, first, by leaving a gap between the breathing part and the observation part of the mask body, that is, opening a first zygomatic bone adaptation incision on the left and right sides of the flexible mask, the first zygomatic bone adaptation incision is arranged in the area formed by the lower part of the observation cavity and the upper part of the breathing cavity, and leaving a gap in the area formed by the lower part of the eye frame of the support frame and the upper part of the mouth and nose frame, the area covered by the user's face is reduced, the overall weight of the snorkeling mask is reduced, and only the necessary coverage area and breathing part are left, so that the user's skin has the function of perception and can directly contact the water body, thereby improving the user's experience;

[0022] Secondly, by setting a gap between the breathing part and the observation part, the capacity of the air bag of the mask body 1 is reduced. The reduced capacity of the air storage bag makes it difficult for the user to breathe if the breathing tube is divided into two channels for exhaust and exhalation. The breathing tube of the present invention is connected to the breathing part, and the breathing part is the part where air is stored, so that the breathing tube is in two-way fluid communication with the outside world. The user inhales and exhausts through the same breathing tube, and there is no need to breathe through a two-channel breathing tube with separate inhalation and exhaust when snorkeling. This makes it easier for the user to breathe when snorkeling, thereby improving the user's experience when snorkeling.

[0023] Thirdly, the breathing tube is designed to be wrapped around the neck and placed at the rear. The bending angle formed by the extension line of the breathing tube connector and the extension line of the tubular body is about 110°. The bending angle is an ergonomic bionic bending angle, which subverts the front design of the traditional breathing tube and extends the channel to the back neck, optimizing the breathing path of the snorkeling mask by ergonomics. Secondly, the air bag of the mask body is relatively flat in shape with smooth lines, and the curved surface of the breathing tube is smooth, thereby reducing the ineffective gas exchange space in the snorkeling mask, reducing airflow dead corners, and accelerating the gas exchange rate. The carbon dioxide in the air bag of the mask body is not easy to accumulate too much, making it easier for users to breathe and improving the user experience when snorkeling.

[0053] Embodiment 1

[0054] To achieve the above purpose, the present invention provides a snorkeling mask, please refer to the attached Figure 1-Figure 24 , including Figure 1It is a structural schematic diagram of a snorkeling mask in one or more embodiments, specifically, comprising a mask body 1 and a breathing tube 2, the interior of the breathing tube 2 is fluidically connected to the interior of the mask body 1, the mask body 1 comprises a breathing part 01 and an observation part 02, the breathing part 01 and the observation part 02 are separated, and a gap is provided between the breathing part 01 and the observation part 02 to expose the cheekbone skin of a person; the breathing tube 2 is connected to the breathing part 01, and the breathing tube 2 is bent and arranged around the neck to enable the breathing part 01 to be directly fluidically connected to the outside world.

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

[0056] When the upper end of the breathing tube 2 is exposed above the water surface, the breathing tube is connected to the outside world, so that gas exchange can be carried out in the mask body 1; when the upper end of the breathing tube 2 is sunk below the water surface, the upper end of the breathing tube 2 is closed to isolate the entry of external fluid, so that water will not enter the mask body 1 and the air in the mask body 1 will not be lost. The user can control the rise and sinking of the breathing tube 2, so that people can exchange gases underwater.

[0057] When a person exhales and inhales, the passage for exhausting gas and the passage for inhaling gas are the same breathing tube 2, that is, "breathing in the same tube".

[0058] In the present embodiment, the capacity of the air bag of the mask body 1 is reduced by setting a gap between the breathing part 01 and the observation part 02. The reduced capacity of the air storage bag makes it difficult for the user to breathe if the breathing tube 2 is set with two channels for exhaust and exhalation. The breathing tube 2 of the present invention is connected to the breathing part 01, and the breathing part 01 is a part for storing air, so that the breathing tube 2 is in two-way fluid communication with the outside world. The user inhales and exhausts through the same breathing tube 2, and there is no need to breathe through the dual-channel breathing tube 2 for separate inhalation and exhaust when snorkeling, which makes it easier for the user to breathe when snorkeling and improves the user experience when snorkeling.

[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 , and the breathing tube plug 1134 is clamped to 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 cavity 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 second sealing grooves 11343 are formed between adjacent second sealing rings 11342 ;

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

[0098] Optionally, a breathing tube plug 1134 is disposed on at least one of the two sides of the mouth and nose frame 113. The number of breathing tube plugs 1134 can be one or two. When the number of breathing tube plugs 1134 is one, the breathing tube plug 1134 is disposed on the left or right side of the mouth and nose frame 113, so that the breathing tube 2 connected to the breathing tube plug 1134 can be arranged around the neck at the rear; when the number of breathing tube plugs 1134 is two, the two breathing tube plugs 1134 can be respectively disposed on the left and right sides of the mouth and nose frame 113, and correspondingly, the number of breathing tubes 2 should also be the same as the number of breathing tube plugs 1134, that is, two, so that the breathing tube 2 connected to the breathing tube plug 1134 can be arranged around the neck at the rear, and the channel extends to the back of the neck, thereby optimizing the breathing path of the snorkeling mask by ergonomics and improving the efficiency of ventilation.

[0099] Optionally, the breathing tube 2 further includes a tubular body 22 and a buoyancy control valve 23, and the buoyancy control valve 23 is disposed 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 breathing tube connector 21 and the tubular body 22 is bent, and the bending angle formed by the extension line of the breathing tube connector 21 and the extension line of the tubular body 21 is α, 100°≤α≤120°; when 100°≤α≤120°, the breathing tube is arranged around the neck and rearward; preferably, α is 110°, and the bending angle formed by the extension line of the breathing tube connector and the extension line of the tubular body is about 110°, and the bending angle is an ergonomic bionic bending angle, which is different from the front setting of the traditional breathing tube 2, and the air intake and exhaust channels are extended to the back neck, and the breathing path of the snorkeling mask is optimized by ergonomics. Secondly, the air bag shape of the mask body 1 is relatively flat and the lines are smooth, and the curved surface of the breathing tube is smooth, thereby reducing the invalid gas exchange space in the snorkeling mask, reducing the airflow dead angle, and accelerating the gas exchange rate. The carbon dioxide in the air bag of the mask body 1 is not easy to accumulate too much, so that the user can breathe more easily, and the user experience when snorkeling is improved.

[0101] Preferably, the breathing tube 2 is flexibly configured, at least the tubular body 22 and the breathing tube connector 21 are flexibly configured, or the breathing tube 2 as a whole may be flexibly configured; optionally, the hardness of the breathing tube 2 is a flexible tube with a Shore hardness of 80, and may be integrally formed of a flexible material such as silicone, polyurethane (PU), thermoplastic elastomer (TPE), etc., which not only has flexible characteristics so that the breathing tube can be folded for easy storage, but also has a certain hardness so that it is not easily deformed during underwater snorkeling and affects the airflow in and out. At the same time, it is also easy for the user to restore the breathing tube 2 from a folded state to an upright state for use.

[0102] The flexible setting makes the breathing tube 2 easy for the user to store and fold. The breathing tube can restore its shape before use and will not be deformed during underwater snorkeling. It is easy to use and carry.

[0103] There are two ways to set the breathing duct of a full-face snorkeling mask. One is to set the breathing duct at the top of the snorkeling mask. The face has to bear the weight of the exhaled gas and the full-face mask, which reduces the user experience. At the same time, because the breathing duct needs to go from the mouth and nose to the exhaust duct on the top for ventilation, the path of gas inhalation and exhaust is long, and people need to use more effort to breathe. The advantage of the present invention over the snorkeling mask with a split mouth-bite breathing tube is that the mask body is set based on the contour of the face and body, and the fit is good. The cheeks and eyes will not be affected or atomized by the exhaled gas, 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 for breathing, and the breathing tube is set at the bottom of the snorkeling mask for breathing. On the left and right sides of the cavity, the breathing tube is rear-mounted and wrapped around the neck to achieve a breathing tube setting, which shortens the path of gas inhalation and exhaust and makes it easier for users to breathe. Since the mask body is set based on the facial contour, the breathing cavity of the snorkeling mask stores a small amount of air, and the amount of accumulated carbon dioxide is also relatively small, which is not easy to accumulate more carbon dioxide, making users feel that breathing is smoother and easier, and the user experience is improved. At the same time, the breathing cavity of the snorkeling mask stores a small amount of air, and the breathing tube is set on the left and right sides of the breathing cavity at the bottom of the snorkeling mask. A one-way valve may not be set between the breathing tube and the breathing cavity. The user can directly exhale and exhaust in time through the breathing tube, which makes breathing easier and improves the user experience.
