Description

Technical Field

[0001] The present invention relates to the technical field of diving equipment, in particular to a life-saving diving breathing tube. Background Art

[0002] The diving snorkel is one of the indispensable equipment in diving activities. Its main function is to provide a breathing channel for divers so that divers can breathe fresh air underwater. Currently, the diving snorkels on the market are mainly divided into three types: wet snorkels, semi-dry snorkels and full-dry snorkels.

[0003] Among them, the wet snorkel has a simple structure and an open top, the semi-dry snorkel has a wave-proof sheet on the top, which can effectively reduce the entry of water, and the fully dry snorkel has a wave-proof cover and a water stop valve on the top, which can more effectively prevent water from entering.

[0004] However, no matter which type of snorkel is used, when the lifeguard dives underwater, a certain amount of water will enter the snorkel. The difference is how much water enters. In the process of lifesaving and rescue, the lifeguard may experience a decline in physical strength due to holding the breath for a long time underwater or frequent breathing. When using the snorkel, it is necessary to actively exhale and drain the water first, that is, to drain the accumulated water in the snorkel by exhaling forcefully before breathing. Then the lifeguard may not completely drain the water in the snorkel due to insufficient exhaust volume, and people will have a stronger desire to inhale after holding their breath for a long time. The lifeguard may choke on water when using the snorkel, which is dangerous. Summary of the Invention

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] First, this invention optimizes the drainage method, transforming traditional active exhalation drainage into suction-assisted drainage. When lifeguards are exhausted or the exhaust volume is insufficient, drainage is automatically completed, avoiding the risk of choking due to incomplete drainage, thereby significantly improving the safety of lifeguards during underwater breathing. Furthermore, this optimized drainage method reduces the operational difficulty and physical exertion of the lifeguard using the snorkel, allowing them to breathe more efficiently, thereby improving their breathing efficiency and helping them better perform rescue operations.

[0024] Second, the present invention incorporates a trigger on the mouthpiece, allowing lifeguards to activate the suction unit simply by biting, without requiring any additional physical movement. This approach avoids disrupting the lifeguard's treading rhythm due to physical manipulation, further conserving energy and allowing them to focus more on the rescue mission. The trigger controls the suction unit by sensing pressure, and a preset pressure threshold is set, triggering it only when the applied pressure reaches a certain level. This design effectively prevents accidental contact with the suction unit when the mouthpiece is impacted or squeezed underwater, avoiding unnecessary drainage and improving the reliability of the snorkel.

[0025] Third, the present invention utilizes a water storage chamber design that allows water in the breathing tube to flow into the water storage chamber under the action of gravity before the connecting hole, thereby reducing the amount of water accumulated in the breathing tube. For semi-dry or fully dry breathing tubes, the amount of water entering the breathing tube is even less, and it is even possible for all the water in the breathing tube to enter the water storage chamber first, allowing it to be drawn out and transferred more quickly by the suction unit. This ensures smooth air flow in the breathing tube when the lifeguard inhales, reducing the risk of choking. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] See also Figures 1 to 10, the present invention provides a technical solution:

[0039] A life-saving diving snorkel, comprising a snorkel 1, a mouthpiece 2 mounted on the inhalation end of the snorkel 1, and a wave-proof design 3 located at the air inlet of the snorkel 1, and further comprising:

[0040] A drainage pipe 4 is connected to the elbow of the breathing tube 1 and the mouthpiece 2. A partition 11 is fixed to the inner wall of the straight portion of the drainage pipe 4. The partition 11 separates the space near the elbow of the breathing tube 1 from the drainage pipe 4 into a water storage chamber 20. A connecting hole 23 is formed on the outer wall of the mouthpiece 2 to connect the breathing tube 1 with the water storage chamber 20.

[0041] The suction part is installed in the drain pipe 4, and the suction part can suck and transfer the water in the water storage chamber 20, and maintain a negative pressure state in the water storage chamber 20;

[0042] The trigger portion is provided on the mouthpiece 2 and controls whether the suction portion is activated or not by sensing pressure.

[0043] At present, the function of a diving snorkel is to enable a diver to breathe while floating on the water surface without having to stick his entire head out of the water. The diving snorkel allows the diver to breathe with his head submerged in the water. This can save energy when floating on the water surface and treading water. On the other hand, burying the head in the water can also facilitate observation of the underwater situation, so as to facilitate rescue operations. When the lifeguard dives into the water, he will spit out the mouthpiece 2 to hold his breath, so that water will enter the snorkel from the mouthpiece 2 and mainly concentrate at the mouthpiece 2.

[0044] Therefore, no matter which type of snorkel is used, when the lifeguard dives underwater, a certain amount of water will enter the snorkel. The difference is how much water enters. During the lifesaving and rescue process, the lifeguard may experience a decrease in physical strength due to holding his breath for a long time underwater or frequently changing breaths. When using the snorkel, he needs to actively exhale and drain the water first, that is, expel the accumulated water in the snorkel by forceful exhalation before breathing. If the lifeguard exhales some air underwater during the period of holding his breath, the lifeguard may not be able to completely drain the water in the snorkel due to insufficient exhaust volume. Moreover, after holding his breath for a long time, the desire to inhale will be stronger. The lifeguard may choke on water when using the snorkel, which is dangerous. Therefore, the method of actively exhaling and draining water when the snorkel is first used needs to be further optimized to reduce or even avoid the possibility of choking. Therefore, this case further optimizes the method of draining the accumulated water in the snorkel, and the specific method is as follows:

[0045] When the lifeguard dives into the water and spits out the mouthpiece 2, the snorkel 1 is completely immersed in the water as the lifeguard dives, so that part of the water enters the snorkel 1.

[0046] When the lifeguard needs to float to the surface for air, he or she puts the mouthpiece 2 back into the mouth and controls the suction part to start by applying pressure to it with teeth. A preset pressure value can be set, and the suction part will not be controlled to start until a certain pressure is reached. This can prevent the mouthpiece 2 from being triggered when it is hit or squeezed to a certain extent underwater, thereby preventing accidental triggering. Then, as the trigger part controls the suction part to start, the suction part sucks and transfers the water in the water storage chamber 20, thereby drawing the accumulated water at the elbow of the breathing tube 1 into the water storage chamber 20 through the connecting hole 23, so as to achieve the purpose of draining the breathing tube 1 and ensure that the air in the breathing tube 1 can flow smoothly.

[0047] In this way, by optimizing the active exhalation drainage method to a method of using the suction part to assist drainage, not only can drainage be automatically completed when the lifeguard is insufficient in physical strength or the exhaust volume is insufficient, thus avoiding the risk of choking and improving the lifeguard's safety and breathing efficiency, but also by designing a trigger part on the mouthpiece 2, the involvement of limbs can be further reduced, thus avoiding disrupting the lifeguard's treading rhythm, and further achieving the effect of saving physical strength.

[0048] Furthermore, it is worth mentioning that Figure 6 Since the breathing tube 1 is generally in a vertical state or a slightly inclined state when in 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 communicating hole 23 under the action of gravity, thereby reducing the amount of water accumulated in the breathing tube 1. In addition, if it is a semi-dry or fully dry breathing tube, since the water intake is even smaller, it is even possible that all the water in the breathing tube 1 enters the water storage chamber 20 first. Therefore, its main purpose is to enable the water in the breathing tube 1 to be drawn out and transferred as quickly as possible. In this way, even when the lifeguard has a strong desire to inhale, the air can still circulate smoothly, further reducing the risk of choking.

[0049] In a preferred embodiment, an embodiment of a suction portion is provided;

[0050] The suction part includes a piston plate 13 slidably mounted 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 to 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 drainage hole 25 for the piston rod 14 to pass through. A drainage channel 16 is designed to penetrate the interior of the partition block 11. The drainage channel 16 is also connected to a bend pipe 21 extending into the water storage chamber 20. The outer wall of the bend pipe 21 is also connected to a branch pipe 22 communicating with the outside of the drain pipe 4. Both the bend pipe 21 and the branch pipe 22 are provided with a one-way valve, and the directions of the two one-way valves are opposite;

[0051] The suction portion further includes a locking portion for locking the piston plate 13 in position.

[0052] For details, please refer to 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 portion (which can be understood as being in a loaded state);

[0053] When the lifeguard puts the mouthpiece 2 into his mouth and applies pressure to it by biting, when the pressure exceeds the preset value, the locking part will be controlled to 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 away from the partition block 11. The generated negative pressure is used to draw the accumulated 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 to complete the transfer of the accumulated water.

[0054] Among them, it is worth mentioning that the design of the bend 21 and the branch pipe 22 and the one-way valve therein enables the piston plate 13 to suck the accumulated water in the water storage chamber 20 through the bend 21 during suction. Conversely, when the piston plate 13 resets by pushing the piston rod 14, the transferred accumulated water can be discharged from the branch pipe 22 to facilitate the next transfer.

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

[0056] The locking part includes a mounting strip 10 fixed to the outer wall of the drain pipe 4, a mounting cavity is opened in the mounting strip 10, and a swing plate 17 is rotatably installed 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 toward the outer wall of the drain pipe 4, and a locking rod 18 is slidably installed through the outer wall of the drain pipe 4 located in the cavity, and one end of the locking rod 18 extending into the drain pipe 4 is set as a bevel tip, and the other end of the locking rod 18 is connected to the swing plate 17 by a pin shaft slide groove structure.

[0057] For details, please refer to Figure 4The enlarged part, first before diving, by manually squeezing the piston rod 14, drives the piston plate 13 to move towards the partition block 11, so that the spring 15 is also compressed and accumulates elastic potential energy;

[0058] At the same time, 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 it, and 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] Also, see Figure 4 The locking rod 18 and the swing plate 17 are connected by a pin shaft and a slide groove structure. By utilizing the fault-tolerant cooperation between the pin shaft and the slide groove, the influence of the lateral displacement of the locking rod 18 caused by the swinging of the swing plate 17 can be eliminated, thereby avoiding interference problems in the stroke.

[0060] In a preferred embodiment, an implementation of a trigger unit is provided:

[0061] The triggering portion includes an air collecting ring 8 mounted on the outer wall of the connection portion of the mouthpiece 2. The air collecting ring 8 is hollow and connected to the mounting bar 10 via an air pipe 9. A support rod 19 is slidably mounted at the connection between the air pipe 9 and the mounting bar 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 holding portion 5, and the holding portion 5 is elastically designed. The interior of the holding portion 5 is set as an air cavity, and the air cavity is connected to the air collecting ring 8 through a delivery pipe 7 built into the mouthpiece 2.

[0063] For details, please refer to Figure 7 By virtue of the elasticity of the bite portion 5 and the design of the hollow cavity inside, when the lifeguard holds the mouthpiece 2 in his mouth, under normal breathing conditions, the teeth only need to fit or lightly bite the bite portion 5. However, when the mouthpiece 2 is initially held in the mouth, the bite portion 5 needs to be firmly bitten, thereby compressing and deforming it. The air pressure in the internal cavity is transported to the air delivery pipe 9 through the delivery pipe 7 and the air collecting ring 8, and the increased internal air pressure is used to push the support rod 19 outward. Figure 4 When it is pushed outward, the spherical structure at its end will drag the swing plate 17 to open, thereby driving the lock rod 18 to move, so as to achieve the purpose of unlocking the piston plate 13;

[0064] Subsequently, by reducing the bite force, the bite portion 5 will automatically elastically recover, and while the air pressure is reduced, the swing plate 17 exerts an extrusion action on it to reset the support rod 19 and wait for the next unlocking.

[0065] During this process, it should be noted that when initially biting the biting portion 5 with force, it is preferred to bite quickly with force, so that the instantaneous change of air pressure in the trachea will be more obvious, thereby ensuring that the support rod 19 can be pushed out. It is necessary to avoid slowly applying the biting force, so as to ensure that the piston plate 13 is unlocked so that it can complete the water transfer work.

[0066] Please see Figure 7 The delivery tube 7 is designed to be built into the mouthpiece 2, so as to avoid the appearance of unnecessary protrusions on the outside of the mouthpiece 2, so that the lifeguard can completely wrap the mouthpiece 2 when holding it in his mouth, and prevent external water from entering through the mouthpiece 2 when breathing.

[0067] In a further preferred embodiment, an intermediate rod 12 is fixed to the outer wall of the partition block 11 near the piston plate 13, and the drainage channel 16 extends along the interior of the intermediate rod 12 and is provided with an outlet on its outer wall. A channel for inserting the intermediate rod 12 is provided inside the piston plate 13 and the piston rod 14, and a hollow hole communicating with the channel is further provided on the outer wall of the piston rod 14, and the hollow hole is able to communicate with the outlet of the drainage channel 16 located on the intermediate rod 12.

[0068] An adjusting sleeve 26 is slidably mounted on the outer wall of the piston rod 14 located in the drain hole 25, and a transfer channel is formed between the adjusting sleeve 26 and the drain hole 25. Blocks or retaining rings are designed at both ends of the adjusting sleeve 26 extending out of the drain hole 25, and a sealing ring 27 is also sleeved 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 aperture 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 a certain amount of air in the drainage channel 16. This will affect the change in air pressure of the piston plate 13 in the above-mentioned firing state, thereby reducing the efficiency of transferring the accumulated water. Therefore, in this embodiment, the main purpose is to further improve the efficiency of transferring the accumulated water.

[0070] Please see the Figure 6 and Figure 7 Therefore, before diving, when the piston plate 13 is moved inward by squeezing the piston rod 14 by hand, the piston rod 14 will synchronously drive the adjustment sleeve 26 to move and block the drainage hole 25, so that Figure 6The space on the right side of the middle piston plate 13 forms a sealed space, and negative pressure is formed as the piston plate 13 moves to the left. At the same time, the accumulated water in the space on the left side 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 on the right side of the piston plate 13 is connected with the drainage channel 16 through the hollow hole. In this way, under the action of negative pressure, a certain negative pressure will be continuously maintained in the drainage channel 16, thereby sucking the water in the water storage chamber 20 into the drainage channel 16 and into the space on the right side of the piston plate 13. The purpose of this design is, on the one hand, to be able to partially transfer the accumulated water in advance, and on the other hand, to keep the drainage channel 16 full of water.

[0071] In this way, when the piston plate 13 is unlocked (i.e., in the firing state), the drainage channel 16 will be connected to the space on the left side of the piston plate 13 again when the piston plate 13 moves to the right, and the accumulated water will be sucked out and transferred. In addition, since the air in the drainage channel 16 is partially sucked out in advance, it will be able to react quickly to changes in pressure after it is filled with liquid, so that the remaining accumulated water in the water storage chamber 20 can be pumped out and transferred in the first time, thereby improving the transfer efficiency of the accumulated water.

[0072] At the same time, the accumulated water in the space on the right side of the piston plate 13 will be discharged from the transfer channel formed between the adjustment sleeve 26 and the drainage hole 25, preparing for the next advance extraction of air.

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

[0074] Please see Figure 8 By designing two valves 24 in the communicating hole 23, the downwardly protruding convex design can allow the accumulated water in the breathing tube 1 to be sucked into the water storage chamber 20. At the same time, when inhaling, due to the changes in flow rate and air pressure in the breathing tube 1, the two valves 24 will automatically close, thus preventing the water in the water storage chamber 20 from flowing back into the breathing tube 1, further improving safety.

[0075] In a preferred embodiment, a plurality of elastic buttons 6 are provided on the outer wall of the biting portion 5, and the elastic buttons 6 correspond to the positions of the posterior molars.

[0076] See Figure 7The enlarged part is designed with an elastic button 6 (similar to an elastic film button), which can increase the space range in the biting part 5 and further increase the change of the air pressure therein. Moreover, through the biting method, multiple elastic buttons 6 can be squeezed at the same time. If they are hit individually underwater, the pressure change is small, which can also play a certain role in preventing accidental touch and prevent the piston plate 13 from being unlocked in advance.

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

[0078] Please see Figure 6 The groove is also designed to partially retract the button to prevent accidental touches underwater.

[0079] In a preferred embodiment, a balancing channel is further provided inside the piston rod 14 to connect the internal channel thereof with the external space.

[0080] Please see Figure 6 The dotted position of the enlarged part can play a certain guiding role because the intermediate rod 12 always slides in the internal channel of the piston rod 14, and the design of the balancing channel is used to balance the pressure of the internal channel of the balancer to prevent it from affecting the movement of the piston plate 13.

[0081] In a preferred embodiment, the gas pipe 9 is designed to fit the outer wall of the drain pipe 4. The gas pipe 9 is divided into two sections that are plugged into each other, and the two sections are connected to the mounting strip 10 and the gas collecting ring 8 respectively; Figure 9 The two-section design of the air supply pipe 9 allows it to be easily disassembled and connected, making it convenient to replace the mouthpiece 2.

[0082] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components recorded in the specification and drawings can also be directly processed according to existing technical common sense without any doubt. At the same time, the connection method of each component adopts the mature conventional means in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so no specific description will be given here.

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