Description

Technical Field

[0001] This application relates to the field of swimming equipment technology, and in particular to a dual-sided shunt breathing tube drain valve. Background Technology

[0002] Current mainstream semi-dry breathing tubes employ a simple single-sided drainage design. Their core feature is a one-way valve at the bottom of the mouthpiece, relying on the pressure difference generated during forceful exhalation to achieve automatic drainage. This design accomplishes both gas exchange and water drainage through a single outlet, relying on the one-way valve at the bottom of the mouthpiece for single-channel drainage. This structure leads to two significant drawbacks: first, the drainage path is singular and has a limited cross-sectional area, easily creating a momentary waterlock effect when the water volume is large, hindering normal breathing; second, the water flow direction completely overlaps with the airflow direction, requiring exhaled air to overcome the gravity of the water column before being expelled, resulting in energy loss and sluggish response. Summary of the Invention

[0003] In view of the aforementioned problems, this application is made to provide a dual-side shunt breathing tube drain valve that overcomes or at least partially solves the aforementioned problems.

[0004] This application discloses a dual-sided diversion breathing tube drain valve, characterized in that it includes a water valve body, two water valve covers, and two soft rubber valve parts; The water valve body includes a mouthpiece, a drain section, and a breathing tube connection section. The side opening of the drain section is connected to the mouthpiece, and the top of the drain section is connected to the breathing tube connection section. Two drain ports are symmetrically provided at the bottom of the drain section. The soft rubber valve is disposed at the drain port, and the water valve cover is connected to the drain port. The water valve cover is used to cover the soft rubber valve.

[0005] Furthermore, the breathing tube connection portion is provided with a sealing element, which is used to connect the breathing tube.

[0006] Furthermore, the bite portion is provided with several strip-shaped protrusions, which are used to connect the bite portion.

[0007] Furthermore, the soft rubber valve is a circular silicone valve.

[0008] Furthermore, the water valve cover is provided with several elliptical holes, and the water valve cover is detachably connected to the drainage part; When the water valve cover is connected to the drainage section, a number of strip-shaped gaps are formed between the water valve cover and the drainage section.

[0009] Furthermore, the water valve body has a symmetrical structure, and the two sides are connected and fixed by ultrasonic welding.

[0010] Furthermore, the drainage section is provided with guide ribs inside, which are symmetrically distributed along the inner wall of the drainage section. The guide ribs are used to guide the water flow to converge towards the drainage outlet.

[0011] Furthermore, the diameter of the drain outlet is 5-8mm, and the center-to-center distance between the two drain outlets is 15-20mm.

[0012] Furthermore, the water valve body is injection molded from food-grade PP material, and the wall thickness of the water valve body is 1.5-2mm.

[0013] A breathing tube includes a mouthpiece, a breathing tube body, and a drain valve, wherein the drain valve is a double-sided shunt breathing tube drain valve as described above, the mouthpiece is connected to the mouthpiece portion, and the breathing tube body is connected to the breathing tube connection portion.

[0014] This application has the following advantages: In the embodiments of this application, addressing the shortcomings of existing technologies where the snorkel has a single drainage path and limited cross-sectional area, the water flow direction completely overlaps with the airflow direction, and the exhaled gas must first overcome the gravity of the water column to be expelled, making it relatively strenuous to use, this application proposes a dual-sided diversion snorkel drainage valve, including a valve body, two valve covers, and two soft rubber valve components; the valve body includes a mouthpiece, a drainage section, and a snorkel connection section, the side opening of the drainage section is connected to the mouthpiece, and the top of the drainage section is connected to the snorkel connection section; the bottom of the drainage section has two symmetrically arranged drainage ports, the soft rubber valve components are disposed at the drainage ports, the valve covers are connected to the drainage ports, and the valve covers are used to cover the soft rubber valve components. By using a dual-sided diversion design, independent valve-type drain valves are added to both sides of the bottom of the mouthpiece, allowing water to be quickly drained from two symmetrical channels simultaneously. This not only doubles the effective water passage area but also achieves physical separation of the breathing airflow and water flow—when exhaling, the air flows through the central main channel, while the water is thrown into the side secondary channels by centrifugal force and discharged, fundamentally solving the problems of blockage risk and low efficiency caused by single-sided drainage.

[0018] 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.

[0019] The inventors discovered through analysis of existing technologies that traditional breathing tubes rely on a one-way valve at the bottom of the mouthpiece to achieve single-channel drainage. This structure leads to two significant drawbacks: first, the drainage path is singular and the cross-sectional area is limited, which can easily create a momentary water lock effect when the water volume is large, hindering normal breathing; second, the water flow direction completely overlaps with the airflow direction, and the exhaled gas must first overcome the gravity of the water column before it can be expelled, resulting in energy loss and response lag.

[0020] Reference Figure 1-2 The present invention illustrates a dual-sided shunt breathing tube drain valve, comprising a valve body 100, two valve covers 200, and two soft rubber valve components. The water valve body 100 includes a mouthpiece 102, a drain section 101, and a breathing tube connection section 103. The side opening of the drain section 101 is connected to the mouthpiece 102, and the top of the drain section 101 is connected to the breathing tube connection section 103. Two drain ports are symmetrically provided at the bottom of the drain section 101. The soft rubber valve is disposed at the drain port, and the water valve cover 200 is connected to the drain port. The water valve cover 200 is used to cover the soft rubber valve.

[0021] It's worth noting that the symmetrical drainage channel design on both sides exponentially increases water drainage efficiency. The dual-valve synchronous opening and closing mechanism not only doubles the drainage cross-sectional area but also optimizes breathing drainage through fluid dynamics. The central airflow channel focuses on gas exchange, while the two side openings handle water drainage, completely eliminating the interference of water flow on breathing impedance in traditional solutions and ensuring low-resistance, smooth ventilation even under high pressure. Employing a dual-channel diversion principle, utilizing the Bernoulli effect in fluid mechanics, when both valves open synchronously, water flow naturally diverts to the lower-pressure dual outlets, significantly reducing the actual blowing force required for the same lung pressure. Real-world testing shows that the blowing pressure required to completely empty the same volume of water is reduced after adopting the dual-channel diversion structure, significantly reducing user fatigue, especially suitable for professional scenarios such as technical diving that require frequent pipe cleaning. Simultaneously, the water flow impact force is evenly distributed across the two valves, extending the lifespan of critical components and allowing users to visually assess the system's health by observing the drainage status on both sides. Furthermore, the standardized water valve cover assembly method supports quick disassembly and maintenance, allowing for internal cleaning without the need for special tools, greatly improving the maintainability and service life of the equipment. Basic drainage function can still be maintained even if one side valve unexpectedly becomes stuck; the matching bite connection system provides double anti-dislodgement protection.

[0022] In the embodiments of this application, addressing the shortcomings of existing breathing tubes where the drainage path is singular and the cross-sectional area is limited, the water flow direction completely overlaps with the airflow direction, and the exhaled gas must first overcome the gravity of the water column to be expelled, making them relatively strenuous to use, this application proposes a dual-sided diversion breathing tube drainage valve, including a water valve body 100, two water valve covers 200, and two soft rubber valve components; the water valve body 100 includes a mouthpiece 102, a drainage section 101, and a breathing tube connection section 103, the side opening of the drainage section 101 is connected to the mouthpiece 102, and the top of the drainage section 101 is connected to the breathing tube connection section 103; the bottom of the drainage section 101 is symmetrically provided with two drainage ports, the soft rubber valve components are disposed at the drainage ports, the water valve covers 200 are connected to the drainage ports, and the water valve covers 200 are used to cover the soft rubber valve components. By using a dual-sided diversion design, independent valve-type drain valves are added to both sides of the bottom of the mouthpiece, allowing water to be quickly drained from two symmetrical channels simultaneously. This not only doubles the effective water passage area but also achieves physical separation of the breathing airflow and water flow—when exhaling, the air flows through the central main channel, while the water is thrown into the side secondary channels by centrifugal force and discharged, fundamentally solving the problems of blockage risk and low efficiency caused by single-sided drainage.

[0023] The following will further describe a dual-sided shunt breathing tube drain valve in this exemplary embodiment.

[0024] Reference Figure 2In one embodiment of this application, the breathing tube connection portion 103 is provided with a sealing element, which is used to connect the breathing tube body 400.

[0025] It should be noted that the breathing tube connection 103 serves as the connection structure between the water valve body and the breathing tube body 400. Its end is equipped with a special sealing element. When the breathing tube and the breathing tube connection 103 are assembled, the sealing element fits tightly against the contact surface of the two, forming a reliable seal by filling the gap. This not only securely connects the breathing tube to prevent it from loosening, but also effectively prevents external water from seeping in or gas from leaking out of the tube, ensuring the airtightness and flowability of the breathing airflow channel, and guaranteeing the safety and smooth operation of the breathing tube when used underwater.

[0026] In one embodiment of this application, the bite portion 102 is provided with a plurality of strip-shaped protrusions, which are used to connect the bite portion.

[0027] It should be noted that the bite mouth portion 102 serves as the connection interface between the water valve body 100 and the bite mouth 300. Its outer surface is provided with several strip-shaped protrusions evenly distributed circumferentially. These protrusions extend axially along the bite mouth portion 102, forming an alternating concave-convex contact surface. When the bite mouth is fitted onto the bite mouth portion 102, the strip-shaped protrusions can form a mechanical engagement with the inner wall of the bite mouth. By increasing the friction and contact tightness between the two, it effectively prevents the bite mouth from loosening or slipping when the user bites or during underwater activities, ensuring a stable connection between the bite mouth 300 and the water valve body 100, while not affecting the wearing comfort of the bite mouth 300.

[0028] In one embodiment of this application, the soft rubber valve is a circular silicone valve.

[0029] It should be noted that the soft rubber valve is a one-way drainage valve. It features a circular silicone diaphragm structure that precisely matches the size of the drain outlet at the bottom of the drain section, completely covering the inside of the outlet. The silicone material itself has good elasticity and water resistance, making it suitable for underwater use. It can flexibly open under water pressure and automatically close when there is no water flow. The circular design ensures a tight seal between the diaphragm and the edge of the drain outlet, preventing localized leakage or incomplete closure, thus achieving both efficient drainage and backflow prevention.

[0030] In one embodiment of this application, the water valve cover 200 is provided with a plurality of elliptical holes, and the water valve cover 200 is detachably connected to the drainage part 101; When the water valve cover 200 is connected to the drainage section 101, a number of strip-shaped gaps are formed between the water valve cover and the drainage section.

[0031] It should be noted that the water valve cover 200 itself has several circumferentially evenly distributed elliptical pores. These pores can prevent larger external impurities from entering the interior and touching the soft rubber valve components without obstructing drainage, thus providing initial protection for the core drainage components. Simultaneously, the water valve cover 200 and the drainage section 101 adopt a detachable connection structure, allowing for easy disassembly and assembly without tools, facilitating subsequent cleaning of the inner wall of the drain outlet or replacement of aging soft rubber valve components. When the water valve cover 200 and the drainage section 101 are fully engaged, several circumferentially arranged strip-shaped pores will naturally form at their connection edges. These strip-shaped pores, together with the elliptical pores of the water valve cover 200 itself, form a double-flow guiding and filtering effect, further guiding the water flow from the drain outlet smoothly outwards, while also providing secondary blocking of small foreign objects to prevent them from clogging the drainage channel. At the same time, it does not affect the normal opening and closing of the soft rubber valve components under water flow impact, ensuring stable drainage and anti-backflow functions of the drain valve.

[0032] In one embodiment of this application, the water valve body 100 has a left-right symmetrical structure, and the two sides are connected and fixed by ultrasonic welding process.

[0033] It should be noted that the water valve body 100 adopts a symmetrical left-right structure design. The left and right sides of the water valve body 100 are connected and fixed by ultrasonic welding. This process does not rely on additional connecting parts such as screws and glue. Instead, it uses high-frequency mechanical vibration to generate high temperature on both sides of the connection surface and melt and bond them together. The joint formed after welding not only has high connection strength, but also achieves seamless sealing, effectively preventing water leakage caused by connection gaps. At the same time, it can also preserve the integrity of the body structure to the greatest extent and meet the reliability requirements of the breather drain valve for long-term underwater use.

[0034] In one embodiment of this application, the drainage section 101 is provided with guide ribs inside, and the guide ribs are symmetrically distributed along the inner wall of the drainage section 101. The guide ribs are used to guide the water flow to converge towards the drain outlet.

[0035] It should be noted that the internal cavity wall of the drainage section 101 is provided with several guide ribs. These guide ribs are symmetrically distributed along the inner wall of the drainage section 101 and precisely correspond to the positions of the two drain outlets at the bottom of the drainage section 101. During the drainage process, the guide ribs can directionally guide the water flow entering the drainage section, preventing the water flow from spreading randomly, stagnating, or flowing along the cavity wall in the cavity. Instead, the water flow is smoothly guided to the corresponding drain outlets on both sides, ensuring that the water flow quickly converges and is discharged through the soft rubber valve. At the same time, the symmetrical distribution structure can ensure that the water inflow to the drain outlets on both sides is uniform, avoiding the difference in drainage efficiency caused by the water flow biased to one side. This further adapts to the core requirements of the dual-sided diversion design and improves the overall drainage effect.

[0036] In one embodiment of this application, the diameter of the drain outlet is 5-8 mm, and the center-to-center distance between the two drain outlets is 15-20 mm.

[0037] It should be noted that both drain outlets at the bottom of the drainage section 101 have a diameter of 5-8mm. This size ensures that water flows out quickly under gravity, preventing water accumulation in the pipe, and also precisely matches the circular silicone valve, allowing the valve to completely cover the edge of the drain outlet, ensuring a one-way seal. This prevents the valve from closing poorly due to an excessively large diameter, or from affecting drainage efficiency due to an excessively small diameter. At the same time, the center-to-center distance between the two drain outlets is 15-20mm. This distance allows the drain outlets to be symmetrically and reasonably distributed at the bottom of the drainage section 101. This avoids the mutual compression and interference caused by water flow convergence when the distance is too close, ensuring a balanced flow on both sides. It also matches the symmetrical structure of the water valve body and the guiding path of the internal guide ribs, allowing the guide ribs to accurately guide the water flow to the corresponding drain outlet, further improving the overall smoothness and stability of drainage.

[0038] In one embodiment of this application, the water valve body 100 is injection molded from food-grade PP material, and the wall thickness of the water valve body 100 is 1.5-2mm.

[0039] It should be noted that the water valve body 100 is made of food-grade PP material through injection molding. This material not only ensures safety in contact with the mouth and meets relevant hygiene standards, but also possesses excellent water resistance, heat and cold resistance, and impact resistance, making it suitable for long-term underwater use. Furthermore, injection molding allows for precise shaping of the complex structures of the mouthpiece, drainage section, and snorkel connection, ensuring dimensional accuracy in each functional area. The water valve body wall thickness is 1.5-2mm, avoiding insufficient structural strength due to excessive thinness, preventing deformation or damage during use due to collisions or bite stress, while also avoiding excessive thickness that would increase overall weight, thus maintaining portability. It also accommodates double-sided ultrasonic welding, ensuring fusion at the weld joints and overall structural stability, further enhancing product durability.

[0040] Reference Figure 2 In one embodiment of this application, a breathing tube is also provided, including a mouthpiece 300, a breathing tube body 400 and a drain valve, wherein the drain valve is a double-sided shunt breathing tube drain valve as described in any of the above claims, the mouthpiece 300 is connected to the mouthpiece portion 102, and the breathing tube body 400 is connected to the breathing tube connection portion 103.

[0041] It should be noted that the mouthpiece 300 is fitted onto the outside of the mouthpiece part 102 of the drain valve. The pre-set strip-shaped protrusions on the mouthpiece part 102 enhance the friction between the two, preventing the mouthpiece 300 from loosening or slipping during use, while ensuring a good fit. The snorkel body 400 is connected to the snorkel connection part 103 of the drain valve. The snorkel connection part 103 has its own sealing components, such as rubber sealing rings and "V"-shaped silicone rings, to fill the gaps between them. This ensures a stable assembly between the snorkel body 400 and the drain valve, and effectively prevents external water from seeping in and gas from leaking out of the tube. The snorkel proposed in this embodiment has the functions of smooth breathing, efficient dual-sided diversion drainage and anti-backflow, and is suitable for use in underwater diving, snorkeling and other scenarios.
