Abstract
Description
Technical Field
[0001] This application relates to the field of diving equipment technology, and in particular to diving devices. Background Technology
[0002] The conservation and display of jellyfish in large aquariums is an important way to protect and educate the public about this animal. Cleaning and maintaining large jellyfish tanks requires staff to wear diving equipment and dive into the water.
[0003] In related technologies, diving equipment includes a diving mask, an air supply structure, an air inlet pipe, and an exhaust pipe. The diving mask includes an air inlet and an exhaust outlet. The air inlet pipe connects the air supply structure and the air inlet, and is used to transfer gas from the air supply structure to the diving mask for the diver to inhale. The exhaust pipe connects to the exhaust outlet, and is used to expel the gas exhaled by the diver from inside the diving mask to the outside of the mask.
[0004] However, the air exhaled by divers remains in the water outside their diving masks. Due to the habits and body structure of jellyfish, these air bubbles can enter the jellyfish's digestive sac, causing fatal damage. Utility Model Content
[0005] Therefore, it is necessary to provide a diving device that addresses the problem that the gas exhaled by divers remains in the water and can further enter the digestive sac of jellyfish, causing fatal damage to the jellyfish.
[0006] A diving device, comprising:
[0007] Face mask, including ventilation openings;
[0008] The first trachea includes a first port and a second port, which are located at opposite ends of the first trachea's extension direction. The first port is connected to the exhaust port, and the second port is used to communicate with the air.
[0009] The mask and at least part of the first trachea are designed to be placed inside the liquid.
[0010] In some embodiments, the diving device further includes:
[0011] A fastener is attached to the end of the first air tube furthest from the mask; the fastener is intended to be positioned outside the liquid.
[0012] In some embodiments, the diving device further includes:
[0013] A floating component is connected to the end of the first air tube furthest from the mask;
[0014] The density of the floating component is less than the density of the liquid.
[0015] In some embodiments, the density of the first trachea is less than the density of the liquid; and / or
[0016] The hardness range of the first trachea is 60HD-70HD.
[0017] In some embodiments, the mask further includes an air inlet; the air inlet and the exhaust outlet are spaced apart.
[0018] The diving device also includes a second air tube and an air supply unit; the air supply unit is spaced apart from the mask; one end of the second air tube is connected to the air inlet, and the other end of the second air tube is connected to the air supply port of the air supply unit.
[0019] In some embodiments, the face mask includes:
[0020] The air intake is located on the mask body;
[0021] The extension is connected to the surface of the mask body, and the exhaust port passes through the extension and the mask body;
[0022] The first air tube is fitted onto the extension part at one end near the mask and is connected to the extension part.
[0023] In some embodiments, the diving device further includes:
[0024] An adhesive component is wrapped around the end of the first trachea near the mask and its extension for connecting the end of the first trachea near the mask and its extension.
[0025] In some embodiments, the diving device further includes:
[0026] The protective component forms a cavity and is connected to the mask body and the first air tube; the adhesive component is located inside the cavity.
[0027] In some embodiments, the extension and the first air tube are integrally formed.
[0028] In some embodiments, the mask covers at least the user's face and ears; and / or
[0029] When the diving device is in use, the exhaust port is located on the side of the air inlet along the direction of gravity.
[0030] The aforementioned diving device includes a mask and a first air tube. The mask includes an exhaust port. The first air tube includes a first opening and a second opening, which are located at opposite ends of the first air tube's extension direction. The first opening communicates with the exhaust port, and the second opening communicates with air. The mask and at least a portion of the first air tube are both intended to be disposed within a liquid.
[0031] The diving device of this application includes a mask for divers to wear, allowing them to work in liquids while wearing the mask. Since the first trachea includes a first opening and a second opening, located at opposite ends of the trachea's extension direction, with the first opening connected to an exhaust port and the second opening connected to air, the diver can directly expel their exhaled air through the first trachea to the outside of the liquid during operations. This prevents exhaled air from entering the jellyfish's digestive sac and thus avoids potentially fatal harm to the jellyfish. Attached Figure Description

[0044] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.
[0045] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.
[0046] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.
[0047] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0048] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.
[0049] It should be noted that the conservation and display of jellyfish in large aquariums is one of the important ways to protect and educate the public about this animal. The cleaning and maintenance of large jellyfish pools require staff to dive into the water, and divers need to wear diving equipment to operate these tasks.
[0050] Jellyfish belong to the subphylum Meconopsis within the phylum Cnidaria. They lack brains, skeletons, hearts, blood, and gills, and their bodies typically contain over 95% water, resembling a transparent umbrella. The diameter of the umbrella-shaped body varies, with some reaching up to 2 meters. Tentacle-like appendages extend along the edge of the umbrella, some reaching lengths of 20-30 meters. Jellyfish lack eyes, but have "spots" in the notches along the edge of the umbrella that sense light intensity. They also lack mouths; after capturing food with their tentacles, they transport it through ducts to a digestive sac at the base of the umbrella-shaped body.
[0051] However, in related technologies, when divers are working underwater while wearing diving equipment, the air exhaled by the divers is released outside the diving mask and remains in the water. Due to the habits and body structure of jellyfish, the air bubbles in the water can enter the jellyfish's digestive sac and cause fatal damage to the jellyfish.
[0052] Meanwhile, during underwater cleaning and maintenance operations, if divers remove jellyfish to areas where work is not required, two problems arise. First, divers need to frequently clean and maintain the jellyfish tank, and the frequent movement of the jellyfish can cause them discomfort. Second, the large size of the jellyfish tanks in aquariums and the extended underwater work time can further exacerbate the damage to the jellyfish.
[0053] See Figure 1 and Figure 2As shown. One embodiment of this application provides a diving device 1, including a mask 11 and a first air tube 12. The mask 11 includes an exhaust port 11a. The first air tube 12 includes a first opening 12a and a second opening 12b, located at opposite ends of the extending direction of the first air tube 12. The first opening 12a communicates with the exhaust port 11a, and the second opening 12b communicates with air. The mask 11 and at least a portion of the first air tube 12 are both disposed within a liquid 2.
[0054] It should be noted that the diving device 1 in this application can be applied to any scenario where divers need to dive, and the environment and scenario for the application of the diving device 1 in this application are not limited here. Since this application aims to solve the problem of jellyfish being harmed by divers wearing the diving device 1 while working in a jellyfish pool, the diving device 1 in this application is particularly suitable for scenarios where divers wear the diving device 1 in a jellyfish pool. This application uses the application of the diving device 1 in the water of an aquarium as an example for illustrative purposes. The jellyfish pool is the environment and place required for jellyfish survival.
[0055] It should be further clarified that, in this application, "water body" and "liquid 2" are the same concept, both referring to the basic environment and material basis necessary for the survival of aquatic animals. Therefore, this application does not restrict the names of "water body" and "liquid 2". Furthermore, "diver" refers to the user who needs to wear diving equipment 1; therefore, this application does not limit the specific user of diving equipment 1.
[0056] Specifically, by setting up a mask 11 and a first trachea 12, the mask 11 is for the diver to wear, allowing the diver to work inside the liquid 2. Since the first trachea 12 includes a first port 12a and a second port 12b, located at opposite ends of the first trachea 12's extension direction, with the first port 12a connected to the exhaust port 11a and the second port 12b connected to air, the diver can exhale through the exhaust port 11a, the first port 12a of the first trachea 12, and the second port 12b of the first trachea 12 sequentially, directly expelling the exhaled air outside the liquid 2. This prevents the exhaled air from remaining inside the liquid 2 and entering the jellyfish's digestive sac, thus avoiding fatal harm to the jellyfish.
[0057] In some embodiments, see Figure 3 As shown, the diving device 1 also includes a fixing member 13. The fixing member 13 is connected to the end of the first air tube 12 away from the mask 11; the fixing member 13 is used to be positioned outside the liquid 2.
[0058] Thus, since the fastener 13 is connected to the end of the first air tube 12 away from the mask 11, and the fastener 13 is positioned outside the liquid 2, meaning the fastener 13 is always positioned outside the liquid 2, the connection between the fastener 13 and the end of the first air tube 12 away from the mask 11 ensures that the end of the first air tube 12 away from the mask 11 is positioned outside the liquid 2. This ensures that the second port 12b of the first air tube 12 is always in communication with the air, further ensuring that the gas exhaled by the diver is directly discharged to the outside of the liquid 2 through the first air tube 12. This further prevents the gas exhaled by the diver from entering the digestive sac of the jellyfish, thus avoiding fatal damage to the jellyfish.
[0059] Furthermore, during operations within the liquid 2, the diver's position may shift or the liquid 2 may flow, causing the first air tube 12 to sway. This swaying can then cause the second opening 12b of the first air tube 12 to enter the liquid 2 at some point. Since the fixing member 13 is connected to the end of the first air tube 12 furthest from the mask 11, the second opening 12b of the first air tube 12 is always in communication with the air outside the liquid 2, thereby improving the diver's reliability during operations.
[0060] Optionally, see Figure 3 As shown, the fastener 13 can be directly fixed to the solid 3 outside the liquid 2, thereby improving the stability and reliability of the fastener 13, and further improving the stability and reliability of fixing the end of the first air tube 12 away from the mask 11, which can further ensure that the second port 12b of the first air tube 12 is always in communication with the air.
[0061] It should be noted that the solid 3 in this application refers to a solid structure other than the liquid 2. The solid 3 can be an operating platform outside the jellyfish pool or the ground outside the jellyfish pool. Here, the concept of solid 3 in this application will not be limited or elaborated.
[0062] In some embodiments, see Figure 4 As shown, the diving device 1 also includes a floating component 14. The floating component 14 is connected to the end of the first air tube 12 away from the mask 11. The density of the floating component 14 is less than the density of the liquid 2.
[0063] Thus, since the floating component 14 is connected to the end of the first air tube 12 furthest from the mask 11, and the density of the floating component 14 is less than that of the liquid 2, the floating component 14 can float on the liquid 2. This allows the floating component 14 to simultaneously float the end of the first air tube 12 furthest from the mask 11 on the liquid 2. On one hand, this ensures that the second opening 12b of the first air tube 12 is always in contact with the air, further ensuring that the diver's exhaled air is directly expelled from the liquid 2 through the first air tube 12, thus preventing the exhaled air from entering the jellyfish's digestive sac and causing fatal harm. On the other hand, by simply setting the floating component 14, the connection between the second opening 12b of the first air tube 12 and the air outside the liquid 2 can be controlled, reducing the manufacturing difficulty of the diving device 1 and facilitating its use by divers. At the same time, the floating component 14 can drive the end of the first air tube 12 away from the mask 11 to float synchronously at any position on the liquid 2, so that the diver does not have to consider the position of the first air tube 12 during underwater operations, which can facilitate the diver's movement and reduce the burden of underwater operations.
[0064] In some embodiments, the density of the first trachea 12 is less than the density of the liquid 2.
[0065] Thus, since the density of the first air tube 12 is less than the density of the liquid 2, meaning the first air tube 12 floats within the liquid 2, and the end of the first air tube 12 furthest from the mask 11 floats on the surface of the liquid 2, on the one hand, no other components are needed to ensure that the end of the first air tube 12 furthest from the mask 11 floats on the liquid 2. This allows for communication between the second opening 12b of the first air tube 12 and the air outside the liquid 2, further simplifying the structure of the diving device 1, reducing its manufacturing difficulty, and facilitating its use by divers. On the other hand, the fact that the end of the first air tube 12 furthest from the mask 11 can float at any position on the liquid 2 means that divers do not need to consider the position of the first air tube 12 during underwater operations, facilitating their movement and reducing the burden of underwater work.
[0066] Furthermore, since the density of the first air tube 12 is less than that of the liquid 2, its overall weight is lighter, which reduces the overall weight of the diving device 1. This reduces the gravitational force exerted on the diver by the diving device 1 while wearing it, thus reducing the load on the diver and facilitating underwater operations. Understandably, the lighter weight of the first air tube 12 reduces the risk of injury to the diver and improves the safety of underwater operations.
[0067] In some embodiments, the hardness of the first trachea 12 is in the range of 60HD-70HD.
[0068] It should be noted that 60HD-70HD refers to a Shore hardness between 60 and 70.
[0069] Thus, since the hardness range of the first air tube 12 is 60HD-70HD, it avoids damage to the jellyfish in the jellyfish pool due to excessive hardness, further preventing injury to the jellyfish. At the same time, it avoids damage to the first air tube 12 due to excessive softness caused by the flow of liquid 2, thereby increasing the service life of the first air tube 12 and thus increasing the overall service life of the diving device 1.
[0070] In some embodiments, see Figure 5 As shown, the mask 11 also includes an air inlet 11b; the air inlet 11b and the exhaust port 11a are spaced apart. The diving device 1 also includes a second air pipe 15 and an air supply component 16; the air supply component 16 is spaced apart from the mask 11; one end of the second air pipe 15 is connected to the air inlet 11b, and the other end of the second air pipe 15 is connected to the air supply port of the air supply component 16.
[0071] Thus, the air supply unit 16 is a component that stores and provides breathing gas, typically containing compressed air or other suitable diving gas mixtures. Connecting the air supply unit 16 to the air inlet 11b of the mask 11 via the second air tube 15 ensures a stable supply of breathing gas to the mask 11, providing a continuous source of air for the diver and ensuring normal underwater breathing. This configuration also helps maintain pressure balance within the mask 11, preventing injury to the diver due to pressure fluctuations. Furthermore, the stable air supply system and well-designed gas flow ensure that the diver will not experience oxygen deficiency or insufficient gas supply during the dive, improving diving safety.
[0072] In some embodiments, see Figure 6 As shown, the mask 11 includes a mask body 111 and an extension 112. An air inlet 11b is provided on the mask body 111. The extension 112 is connected to the surface of the mask body 111, and an exhaust port 11a passes through the extension 112 and the mask body 111. A first air tube 12, with one end near the mask 11, is fitted onto and connected to the extension 112.
[0073] Thus, the exhaust port 11a extends through the extension 112 and the mask body 111, allowing the diver's exhaled air to be discharged from the mask 11 through the exhaust port 11a. The extension 112 provides a certain extension space for the exhaust port 11a, which helps to guide the exhaled air to be discharged more smoothly, avoids the exhaled air from forming eddies or backflows inside the mask 11, and reduces interference with the breathing environment inside the mask 11.
[0074] Furthermore, the extension 112 is connected to the surface of the mask body 111, increasing the stability of the mask 11 structure. It can, to a certain extent, disperse the pulling force of the first air tube 12 on the mask 11, preventing damage or deformation to the mask body 111 caused by the connection of the first air tube 12 and the force generated by gas flow. In addition, the extension 112 can also protect the exhaust port 11a on the mask body 111, preventing external objects from colliding with or blocking the exhaust port 11a, ensuring the normal operation of the exhaust function.
[0075] In some embodiments, the diving device 1 further includes an adhesive element. The adhesive element is wrapped around one end of the first air tube 12 near the mask 11 and the extension 112 for connecting the one end of the first air tube 12 near the mask 11 and the extension 112.
[0076] Thus, by wrapping the adhesive around the end of the first air tube 12 near the mask 11 and the extension 112, the adhesive can firmly fix the two together, preventing the air tube and extension 112 from loosening or falling off during diving due to water flow, diver activities, or other external forces, ensuring that the exhaust channel for breathing gas remains unobstructed and stable. At the same time, the adhesive can fill any tiny gaps that may exist between the first air tube 12 and the extension 112, forming a good seal and preventing exhaled gas from leaking from these gaps. This ensures the normal operation of the exhaust system, maintains a suitable air pressure and breathing environment inside the mask 11, and prevents diving discomfort or safety hazards due to gas leakage.
[0077] In some embodiments, the diving device 1 further includes a protective member. The protective member surrounds and forms a cavity, and is connected to the mask body 111 and the first air tube 12; an adhesive member is disposed within the cavity.
[0078] Thus, the protective component forms a cavity that encloses the adhesive component, preventing it from being directly exposed to the external environment and protecting it from water erosion and scratches or impacts from other external objects. This extends the service life of the adhesive component and ensures stable connection performance. Furthermore, the protective component connects to the mask body 111 and the first air tube 12, providing reinforcement and support between them. It disperses the tension of the air tube on the mask 11, making the connection between the mask 11 and the air tube more secure, reducing the possibility of loosening or damage to the connection due to diver activity or water flow, and improving the structural strength and reliability of the entire diving device 1.
[0079] In some embodiments, the extension 112 and the first air tube 12 are integrally formed structures.
[0080] Thus, on the one hand, the one-piece molded structure has no connecting gaps, resulting in higher overall strength compared to spliced or assembled structures. During diving, it can better withstand the impact force from the liquid 2, the pulling force generated by the diver's activities, and the pressure from the flow of breathing gas, reducing the risk of cracking or damage due to structural weaknesses and improving the reliability and safety of the diving device 1. On the other hand, the one-piece molding eliminates the interfaces between components, fundamentally preventing gas leakage caused by poor sealing. This helps maintain stable air pressure inside the mask 11, providing a good breathing environment for the diver and avoiding breathing difficulties or other safety hazards caused by gas leakage.
[0081] In some embodiments, the mask 11 covers at least the user's face and ears.
[0082] In this way, the face mask fits snugly against the face, forming a relatively sealed space to prevent liquid 2 from entering the mask 11, ensuring that the diver's face remains dry underwater, providing a stable environment for breathing, and avoiding direct irritation and interference from water. Furthermore, it protects the face from impacts and scratches from underwater debris and plankton, as well as from injuries caused by sharp objects encountered during diving. The ear cover protects the ears from the direct effects of water pressure, reducing discomfort or damage caused by changes in water pressure, such as ear pain, tinnitus, or even eardrum rupture. It also helps to prevent cold water from stimulating the ears, reducing the risk of discomfort caused by ear chills.
[0083] In some embodiments, when the diving device 1 is in use, the exhaust port 11a is located on the side of the air inlet 11b along the direction of gravity.
[0084] Thus, since exhaled air contains more carbon dioxide, which is denser than fresh air, it will naturally sink under the influence of gravity. Placing the exhaust port 11a on the side of the air inlet 11b along the direction of gravity helps to make the exhaled air flow more smoothly to the exhaust port 11a, facilitating its discharge from the mask 11, thereby improving exhaust efficiency, reducing the amount of exhaled air remaining in the mask 11, and keeping the air inside the mask 11 fresh.
[0085] Furthermore, this design prevents exhaled air from directly mixing with the fresh air entering through the air inlet 11b. Improperly positioned exhaust outlet 11a and air inlet 11b could cause exhaled air to interfere with the normal inflow of fresh air, affecting the diver's breathing experience. By placing the exhaust outlet 11a on the side of the air inlet 11b along the direction of gravity, fresh air and exhaled air flow along different paths, ensuring that fresh air enters the mask 11 more purely for the diver's breathing, improving breathing quality and safety.
[0086] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0087] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
