Description

Technical Field

[0001] This invention relates to the field of diving equipment technology, specifically to a life-saving diving breathing tube. Background Technology

[0002] A snorkel is an indispensable piece of equipment in diving activities. Its main function is to provide a breathing channel for divers, enabling them to breathe fresh air underwater. Currently, snorkels on the market are mainly divided into three types: wet snorkels, semi-dry snorkels, and fully dry snorkels.

[0003] Among them, wet breathing tubes have a simple structure with an open top, semi-dry breathing tubes have a baffle plate at the top to effectively reduce water entry, while fully dry breathing tubes have a baffle cover and a water stop valve at the top to more effectively prevent water from entering.

[0004] However, regardless of the type of snorkel, a certain amount of water will enter the snorkel when a lifeguard dives underwater. The difference lies in the amount of water entering. During a rescue operation, lifeguards may experience a decline in physical strength due to prolonged underwater breath-holding or frequent breathing. When using a snorkel, it is necessary to actively exhale and expel the water from the snorkel before breathing. If the lifeguard does not expel enough water, the water in the snorkel may not be completely expelled. Furthermore, after holding one's breath for a long time, the urge to inhale is stronger, which may lead to choking on water when using a snorkel, thus causing danger. Summary of the Invention

[0005] The purpose of this invention is to provide a life-saving diving breathing tube to solve at least one technical problem existing in the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a lifesaving diving snorkel, comprising a snorkel, a mouthpiece installed at the inhalation end of the snorkel, and a wave-proof design located at the air inlet of the snorkel, and further comprising:

[0007] A drain pipe is connected to the bend of the breathing tube and the mouthpiece. The inner wall of the straight section of the drain pipe is fixed with a partition block. The partition block divides the space near the bend of the breathing tube into a water storage chamber. The outer wall of the mouthpiece is provided with a connecting hole that allows the breathing tube to communicate with the water storage chamber.

[0008] The suction unit is installed inside the drain pipe and can draw water from the water storage chamber and maintain a negative pressure state inside the water storage chamber.

[0009] A trigger part is provided on the mouthpiece, and the trigger part controls whether the suction part is activated by sensing pressure.

[0010] Optionally, the suction unit includes a piston plate slidably mounted on the inner wall of the straight drain pipe, and a spring is connected between the piston plate and the partition block. A piston rod is fixed to the outer wall of the piston plate away from the partition block, and one end of the piston rod extends out of the drain pipe and is fixed with a button. A drain hole is opened on the outer wall of the drain pipe so that the piston rod can pass through. A drain channel is designed through the interior of the partition block. The drain channel is also connected to a bend extending into the water storage chamber. A branch pipe communicating with the outside of the drain pipe is also connected to the outer wall of the bend. One-way valves are provided in both the bend and the branch pipe, and the two one-way valves are in opposite directions.

[0011] The suction unit also includes a locking unit for locking the position of the piston plate.

[0012] Optionally, the locking part includes a mounting strip fixed to the outer wall of the drain pipe. The mounting strip has a mounting cavity, and a swing plate is rotatably mounted in the mounting cavity. A torsion spring is installed between the swing plate and the inner wall of the cavity, and the torsion spring applies a torsional force to the swing plate to rotate and fit against the outer wall of the drain pipe. A locking rod is slidably mounted through the outer wall of the drain pipe located in the cavity. One end of the locking rod extending into the drain pipe is set as a beveled tip, and the other end of the locking rod is connected to the swing plate through a pin-slide groove structure.

[0013] Optionally, the trigger part includes an air collecting ring installed on the outer wall of the bite joint. The air collecting ring is hollow and is connected to the mounting strip through an air supply pipe. A support rod is slidably installed at the connection between the air supply pipe and the mounting strip. The end of the support rod is a spherical structure and is embedded in the gap between the swing plate and the outer wall of the drain pipe.

[0014] The inner ring wall of the mouthpiece is provided with a biting part, and the biting part is elastically designed. The inside of the biting part is set as an air cavity, and the air cavity is connected to the air collecting ring through a delivery tube built into the mouthpiece.

[0015] Optionally, the separator block is fixed with a middle rod near the outer wall of the piston plate, and the drainage channel extends along the inside of the middle rod and has an outlet on its outer wall. The piston plate and piston rod have a channel for the middle rod to be inserted inside. The outer wall of the piston rod also has a perforation communicating with the channel, and the perforation and the outlet of the drainage channel on the middle rod can be correspondingly communicated.

[0016] An adjusting sleeve is slidably installed on the outer wall of the piston rod located inside the drain hole, and a transfer channel is formed between the adjusting sleeve and the drain hole. The two ends of the adjusting sleeve extending out of the drain hole are respectively designed with a stop block or a stop ring, and a sealing ring is also fitted on the outer wall of the adjusting sleeve located outside the drain pipe, and the diameter of the sealing ring is larger than the diameter of the drain hole.

[0017] Optionally, two valves are installed on the inner wall of the connecting hole. Both valves are convex in design and the convex direction faces the inside of the water storage cavity.

[0018] Optionally, the outer wall of the biting part is provided with a plurality of elastic buttons, and the elastic buttons correspond to the positions of the posterior molars.

[0019] Optionally, the drain pipe has a groove at the drain hole outlet, and the groove allows the button on the piston rod to enter.

[0020] Optionally, the piston rod may also have a balance channel inside, which allows its internal passage to communicate with the external space.

[0021] Optionally, the outer walls of the gas supply pipe and the drain pipe are designed to fit together. The gas supply pipe is divided into two sections that are inserted into each other, and the two sections are respectively connected to the mounting strip and the gas collection ring.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] I. This invention optimizes the drainage method, transforming the traditional active exhalation drainage into drainage assisted by a suction unit. When the lifeguard's strength is insufficient or the exhalation volume is inadequate, drainage can be automatically completed, avoiding the risk of choking due to incomplete drainage. This significantly improves the safety of lifeguards during underwater breathing. Furthermore, the optimized drainage method reduces the difficulty and physical exertion of using a snorkel, allowing lifeguards to breathe more efficiently, thus improving breathing efficiency and facilitating better rescue operations.

[0024] II. This invention, by designing a trigger on the mouthpiece, allows lifeguards to control the activation of the suction unit by biting down, eliminating the need for additional limb movements. This method avoids disrupting the lifeguard's treading rhythm due to limb manipulation, further conserving energy and allowing the lifeguard to focus more on the rescue mission. Furthermore, the trigger controls the suction unit's activation by sensing pressure and has a preset pressure value; it only activates when the applied pressure reaches a certain threshold. This design effectively prevents accidental activation of the suction unit when the mouthpiece is impacted or squeezed underwater, avoiding unnecessary water drainage and improving the reliability of the breathing tube.

[0025] Third, the design of this invention, through the water storage chamber, allows water in the breathing tube to enter the water storage chamber before the connecting hole under the influence of gravity, reducing the water content in the breathing tube. For semi-dry or fully dry breathing tubes, the amount of water entering is even less, and it is even possible that all the water in the breathing tube enters the water storage chamber first, so that it can be extracted and transferred by the suction unit more quickly, ensuring that the air in the breathing tube can flow smoothly when the lifeguard inhales, reducing the risk of choking.

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Please see Figures 1 to 10The present invention provides a technical solution:

[0039] A lifesaving diving snorkel includes a snorkel 1, a mouthpiece 2 installed at the inhalation end of the snorkel 1, and a wave-proof design 3 located at the air inlet of the snorkel 1, and further includes:

[0040] The drain pipe 4 is connected to the elbow of the breathing tube 1 and the mouthpiece 2. The inner wall of the straight part of the drain pipe 4 is fixed with a partition block 11. The partition block 11 divides the space of the drain pipe 4 near the elbow of the breathing tube 1 into a water storage chamber 20. The outer wall of the mouthpiece 2 is provided with a connecting hole 23 that connects the breathing tube 1 and the water storage chamber 20.

[0041] The suction unit is installed in the drain pipe 4, and the suction unit can draw and transfer the water in the water storage chamber 20, and maintain the negative pressure state in the water storage chamber 20.

[0042] A trigger part is provided on the mouthpiece 2, and the trigger part controls whether the suction part is activated by sensing pressure.

[0043] Currently, the purpose of a diving snorkel is to allow divers to breathe without having to expose their entire head above water. By using a diving snorkel, the head can be submerged in the water to breathe. This saves energy when treading water on the surface, and also allows for easier observation of the underwater situation, facilitating rescue operations. When a lifeguard dives into the water, they will exhale through the mouthpiece 2 to hold their breath. As a result, water will enter the snorkel through the mouthpiece 2 and mainly concentrate at that point.

[0044] Therefore, regardless of the type of snorkel, a certain amount of water will enter the snorkel when a lifeguard dives underwater; the difference lies in the amount. During rescue operations, lifeguards may experience fatigue due to prolonged breath-holding or frequent breathing. Since snorkels require active exhalation to expel water before breathing, if the lifeguard exhales some air underwater, the water may not be completely expelled. Furthermore, the urge to inhale is strong after prolonged breath-holding, potentially leading to choking on water while using the snorkel, posing a danger. Therefore, the method of active exhalation to expel water when first using a diving snorkel needs further optimization to reduce or even avoid choking. This paper further optimizes the method of expelling water from diving snorkels, as follows:

[0045] When the lifeguard dives into the snorkel and spits out the mouthpiece 2, the snorkel 1 will be completely submerged in water as the lifeguard descends, since it is usually connected to the diving mask. This will allow some water to enter the snorkel.

[0046] When the lifeguard needs to surface to breathe, he puts the mouthpiece 2 back into his mouth and controls the suction unit to start by applying pressure with his teeth. A preset pressure value can be set, and the suction unit will only start after a certain pressure is reached. This can prevent the mouthpiece 2 from being triggered by collision or compression underwater, thus preventing accidental activation. When the suction unit is activated by the trigger, the suction unit draws water from the water storage chamber 20 and transfers it. This allows the water accumulated at the elbow of the breathing tube 1 to be drawn into the water storage chamber 20 through the connecting hole 23, thereby draining the breathing tube 1 and ensuring that the air in the breathing tube 1 can flow smoothly.

[0047] By optimizing the active exhalation and drainage method into a suction-assisted drainage method, the lifeguard can automatically complete drainage when the lifeguard is short of energy or the amount of air expelled, avoiding the risk of choking and improving the lifeguard's safety and breathing efficiency. Furthermore, by designing a trigger on the mouthpiece 2, the involvement of the limbs can be further reduced, avoiding disruption of the lifeguard's treading rhythm and further saving energy.

[0048] Moreover, it is worth mentioning that, see Figure 6 Since the breathing tube 1 is generally in a vertical or slightly tilted position during use, the design of the water storage chamber 20 allows the water in the breathing tube 1 to enter the water storage chamber 20 before the connecting hole 23 under the action of gravity. This reduces the water content in the breathing tube 1. Furthermore, if it is a semi-dry or fully dry breathing tube, the water intake is even less, so it is possible that all the water in the breathing tube 1 will enter the water storage chamber 20 first. Therefore, its main purpose is to allow the water in the breathing tube 1 to be extracted and transferred as quickly as possible. This ensures smooth airflow even when the lifeguard has a strong urge to breathe, further reducing the risk of choking.

[0049] In a preferred embodiment, an implementation of the suction section is provided;

[0050] The suction unit includes a piston plate 13 that is slidably installed on the inner wall of the straight pipe of the drain pipe 4, and a spring 15 is connected between the piston plate 13 and the partition block 11. A piston rod 14 is fixed on the outer wall of the piston plate 13 away from the partition block 11, and one end of the piston rod 14 extends out of the drain pipe 4 and is fixed with a button. The outer wall of the drain pipe 4 is provided with a drain hole 25 through which the piston rod 14 can pass. A drain channel 16 is designed through the interior of the partition block 11. The drain channel 16 is also connected to a bend pipe 21 that extends into the water storage chamber 20. The outer wall of the bend pipe 21 is also connected to a branch pipe 22 that communicates with the outside of the drain pipe 4. Both the bend pipe 21 and the branch pipe 22 are provided with one-way valves, and the two one-way valves are in opposite directions.

[0051] The suction section also includes a locking section for locking the position of the piston plate 13.

[0052] For details, please refer to [link / reference]. Figure 6 and Figure 7 During the diving phase, the spring 15 is in a compressed state (i.e., accumulating elastic potential energy) and the position of the piston plate 13 is locked by the locking part (which can be understood as being in a loaded state).

[0053] When the lifeguard puts the mouthpiece 2 into their mouth and applies pressure by biting it, when the pressure exceeds a preset value, the locking part will release the locking effect on the piston plate 13. At the same time, the elastic potential energy of the spring 15 is released (which can be understood as the firing state), and the piston plate 13 is pushed to move away from the partition block 11. The negative pressure generated is used to pump the water in the water storage chamber 20 into the space between the partition block 11 and the piston plate 13 through the drainage channel 16, so as to complete the transfer of water.

[0054] Of particular note is the design of the bend 21, the branch pipe 22, and the one-way valve inside them. This design allows the piston plate 13 to draw water from the water storage chamber 20 through the bend 21 during suction. Conversely, when the piston plate 13 moves to its reset position by pushing the piston rod 14, it can discharge the transferred water from the branch pipe 22 for the next transfer.

[0055] In a further preferred embodiment, an implementation of the locking part is provided:

[0056] The locking part includes a mounting strip 10 fixed to the outer wall of the drain pipe 4. The mounting strip 10 has a mounting cavity, and a swing plate 17 is rotatably mounted in the mounting cavity. A torsion spring is installed between the swing plate 17 and the inner wall of the cavity, and the torsion spring applies a torsional force to the swing plate 17 to rotate and fit against the outer wall of the drain pipe 4. A locking rod 18 is slidably mounted through the outer wall of the drain pipe 4 located in the cavity. One end of the locking rod 18 that extends into the drain pipe 4 is set as a beveled tip, and the other end of the locking rod 18 is connected to the swing plate 17 through a pin-slide structure.

[0057] For details, please refer to [link / reference]. Figure 4The amplification part first moves the piston plate 13 towards the partition block 11 by squeezing the piston rod 14 before diving, thereby compressing the spring 15 and accumulating elastic potential energy.

[0058] Meanwhile, due to the design of the swing plate 17 and the torsion spring on the inner wall of the cavity, the inclined tip of the locking rod 18 can be inserted into the drain pipe 4. When the piston plate 13 contacts it, it will press it back until the piston plate 13 passes over, and then the locking rod 18 will pop out again, thereby achieving the purpose of locking the position of the piston plate 13 (which can be understood as the loading process).

[0059] Furthermore, see Figure 4 The locking rod 18 and the swing plate 17 are connected by a pin and groove structure. By utilizing the fault-tolerant fit between the pin and the groove, the influence of the lateral displacement of the locking rod 18 caused by the swing plate 17 swinging can be eliminated, so as to avoid interference problems in the stroke.

[0060] In a preferred embodiment, an implementation of the triggering part is provided:

[0061] The triggering part includes an air collecting ring 8 installed on the outer wall of the mouthpiece 2 connection part. The air collecting ring 8 is hollow, and the air collecting ring 8 is connected to the mounting strip 10 through an air supply pipe 9. A support rod 19 is slidably installed at the connection between the air supply pipe 9 and the mounting strip 10. The end of the support rod 19 is a spherical structure and is embedded in the gap between the swing plate 17 and the outer wall of the drain pipe 4.

[0062] The inner ring wall of the mouthpiece 2 is provided with a biting part 5, and the biting part 5 is elastically designed. The inside of the biting part 5 is set as an air cavity, and the air cavity is connected to the air collecting ring 8 through the delivery pipe 7 built into the mouthpiece 2.

[0063] For details, please refer to [link / reference]. Figure 7 Through the elasticity of the bite-holding part 5 and the design of the internal air cavity, when a lifeguard puts the mouthpiece 2 in their mouth, under normal breathing conditions, their teeth only need to be close to or lightly bite the bite-holding part 5. However, when initially putting the mouthpiece 2 into their mouth, they need to bite down hard on the bite-holding part 5, thereby compressing and deforming it. The air pressure in its internal air cavity is delivered to the air supply pipe 9 through the delivery pipe 7 and the air collection ring 8. The increased internal air pressure pushes the support rod 19 outward. (See reference...) Figure 4 When it is pushed outward, the spherical structure at its end will drag the swing plate 17 to open, thereby driving the locking rod 18 to move, so as to unlock the piston plate 13.

[0064] Subsequently, by reducing the biting force, the biting part 5 will automatically and elastically return to its original position. As the air pressure decreases, the squeezing action of the swing plate 17 will cause the support rod 19 to reset, ready for the next unlocking.

[0065] During this process, it is important to note that when initially applying force to bite the holding part 5, a rapid force should be applied first. This will result in a more significant instantaneous change in air pressure within the trachea, thus ensuring that the support rod 19 is pushed out. A slow application of biting force should be avoided, as this will ensure that the piston plate 13 can be unlocked and complete the water transfer process.

[0066] Please refer to Figure 7 The delivery tube 7 is designed to be built into the mouthpiece 2. This avoids the presence of extra protrusions on the outside of the mouthpiece 2, so that the lifeguard can completely cover the mouthpiece 2 when it is put into his mouth, and prevent water from entering through the mouthpiece 2 when breathing.

[0067] In a further preferred embodiment, the partition block 11 is fixed with an intermediate rod 12 near the outer wall of the piston plate 13, and the drainage channel 16 extends along the interior of the intermediate rod 12 and has an outlet on its outer wall. The piston plate 13 and the piston rod 14 have channels for the intermediate rod 12 to be inserted. The outer wall of the piston rod 14 also has a perforation communicating with the channel, and the perforation and the outlet of the drainage channel 16 on the intermediate rod 12 can communicate with each other.

[0068] An adjusting sleeve 26 is slidably installed on the outer wall of the piston rod 14 located inside the drain hole 25, and a transfer channel is formed between the adjusting sleeve 26 and the drain hole 25. The two ends of the adjusting sleeve 26 extending out of the drain hole 25 are respectively designed with a stop block or a stop ring, and a sealing ring 27 is also fitted on the outer wall of the adjusting sleeve 26 located outside the drain pipe 4, and the diameter of the sealing ring 27 is larger than the diameter of the drain hole 25.

[0069] Since there is air in the water storage chamber 20 and the breathing tube 1, there will also be some air in the drainage channel 16. This will affect the change of air pressure in the piston plate 13 under the above firing state, thereby reducing the efficiency of transferring accumulated water. Therefore, in this embodiment, the main purpose is to further improve the efficiency of transferring accumulated water.

[0070] Please refer to the following: Figure 6 and Figure 7 Therefore, before diving, when the piston plate 13 is moved inward by squeezing the piston rod 14, the piston rod 14 will simultaneously move the adjusting sleeve 26 to block the drain hole 25, so that... Figure 6The space to the right of the piston plate 13 forms a sealed space, and a negative pressure is formed as the piston plate 13 moves to the left. At the same time, the water in the space to the left of the piston plate 13 will be discharged outward through the drainage channel 16 and the branch pipe 22 until the outlet of the drainage channel 16 on the middle rod 12 completely enters the channel inside the piston rod 14 and passes the position of the piston plate 13. At this time, the negative pressure space to the right of the piston plate 13 is connected to the drainage channel 16 through the perforation. In this way, under the action of negative pressure, the drainage channel 16 will maintain a certain negative pressure, thereby drawing the water in the water storage chamber 20 into the drainage channel 16 and into the space to the right of the piston plate 13. The purpose of this design is, on the one hand, to transfer some of the accumulated water in advance, and on the other hand, to keep the drainage channel 16 full of water.

[0071] When the piston plate 13 is unlocked (i.e., in the firing state), as the piston plate 13 moves to the right, the drainage channel 16 will reconnect with the space on the left side of the piston plate 13 and draw out and transfer the accumulated water. Furthermore, since some air has been drawn out of the drainage channel 16 in advance, it can react quickly to pressure changes after being filled with liquid, thereby allowing the remaining accumulated water in the water storage chamber 20 to be drawn out and transferred in the first instance, improving the efficiency of water transfer.

[0072] Meanwhile, the water accumulated in the space on the right side of the piston plate 13 will be discharged through the transfer channel formed between the adjusting sleeve 26 and the drain hole 25, in preparation for the next early air extraction.

[0073] In a further preferred embodiment, two valves 24 are installed on the inner wall of the connecting hole 23. Both valves 24 are convex in design and the convex direction faces the inside of the water storage cavity 20.

[0074] Please refer to Figure 8 By designing two valves 24 inside the connecting hole 23, their downward protruding convex design allows water accumulated in the breathing tube 1 to be drawn into the water storage chamber 20. At the same time, during inhalation, due to changes in flow rate and air pressure in the breathing tube 1, the two valves 24 will automatically close, thus preventing water in the water storage chamber 20 from flowing back into the breathing tube 1, further improving safety.

[0075] In a preferred embodiment, the outer wall of the biting part 5 is provided with a plurality of elastic buttons 6, and the elastic buttons 6 correspond to the positions of the molars.

[0076] See Figure 7In the enlarged section, the design of the elastic button 6 (similar to the elastic membrane button) increases the internal space of the gripping part 5 and further improves the change of internal air pressure. Moreover, the biting action allows multiple elastic buttons 6 to be squeezed simultaneously. If a single button is impacted underwater, its pressure change is small, which can also play a certain role in preventing accidental touches and preventing premature unlocking of the piston plate 13.

[0077] In a preferred embodiment, the drain pipe 4 is provided with a groove at the outlet of the drain hole 25, and the groove allows the button on the piston rod 14 to enter.

[0078] Please refer to Figure 6 The groove design is also intended to partially house the button to prevent accidental activation underwater.

[0079] In a preferred embodiment, the piston rod 14 is further provided with a balance channel that allows its internal passage to communicate with the external space.

[0080] Please refer to Figure 6 The dotted lines in the magnified section indicate that the intermediate rod 12 always slides within the internal channel of the piston rod 14, which provides a certain guiding function. The design of the balance channel is used to balance the pressure within the internal channel of the balancer to prevent it from affecting the movement of the piston plate 13.

[0081] In a preferred embodiment, the outer walls of the gas supply pipe 9 and the drain pipe 4 are designed to fit together. The gas supply pipe 9 is divided into two interconnected sections, which are respectively connected to the mounting strip 10 and the gas collecting ring 8; see also Figure 9 The two-section design of the air supply tube 9 allows for easy disassembly and connection, making it convenient to replace the mouthpiece 2.

[0082] The standard parts used in this embodiment can be purchased directly from the market, while the non-standard structural parts described in the specification and drawings can be processed directly based on existing technical knowledge without any doubt. At the same time, the connection methods of each component adopt mature conventional methods in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so they will not be described in detail here.

[0083] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
