Description

Technical Field

[0001] The present invention relates to the technical field of diving masks, and specifically to a diving mask for underwater detection. Background Art

[0002] Although the first protection part of the diving mask in contact with the human face uses a flexible material for contact, in order to ensure stability, this flexible first protection part still needs to have a certain rigidity to avoid water leakage. At the same time, the back side of the mask is fastened by straps, thus forming a waterproof space for the face.

[0003] However, during diving, since the underwater pressure changes gradually with depth, the squeezing force of the mask on the human face is not constant. When the water pressure increases, the squeezing force of the mask on the human face will also increase significantly, giving a feeling that the mask is buckling tighter and tighter. In addition to bones, the human face also has epidermis and soft tissues on the outer surface. When the mask pressure increases, the first protection part of the mask will press tightly on the epidermis and remain relatively stationary, but the skin is soft and movable. Therefore, when the water pressure increases, the mask will have an action of tearing the skin on the human face, which will cause the human face to become rather distorted. Moreover, with the synchronous movement of the skin and the first protection part, it is easy to break the original tight sealing state under the action of facial bones in different regions, generating gaps, resulting in sealing failure, affecting vision and breathing. Therefore, it is necessary to provide a diving mask for underwater detection to solve the above technical problems. Summary of the Invention

[0004] The purpose of the present invention is to provide a diving mask for underwater detection to solve the problems raised in the above background art, that is, the underwater pressure increases with the increase of depth, resulting in an increase in the squeezing force of the mask on the face, the sealing state between the mask and the face is damaged, easy to generate gaps, resulting in water leakage, affecting vision and breathing. The technical solution of the present invention provides a solution significantly different from the prior art for the technical problem that the prior art solutions are too single.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A diving mask for underwater detection, including a body. A connecting cylinder is installed on the outer side of the upper jaw of the body, and a frame plate is connected to the outer side of the connecting cylinder. An activity plate is arranged above the frame plate. A plate member is connected to the inner side of the connecting cylinder. A first protection part also adheres to the inner surface of the body. It further includes an adjustment mechanism and a reaction mechanism. The adjustment mechanism cooperates with the reaction mechanism to enable a diver to trigger the reaction mechanism adaptively through the gradually increasing pressure during diving, so as to ensure the sealing between the body and the diver's face.

[0006] In a further embodiment, a support plate is installed inside the frame plate, and a telescopic rod is connected above the support plate. A spring is clamped on the outer side of the telescopic rod.

[0007] In a further embodiment, the adjusting mechanism includes a pressure rod connected to the bottom of the movable plate, and a sawtooth is provided at the end of the pressure rod, and a scroll groove is also provided at the end of the pressure rod.

[0008] In a further embodiment, the reaction mechanism includes a plurality of reaction cylinders connected to the inner side of the plate member, and plastic bags are correspondingly arranged on the inner walls of the plurality of reaction cylinders. A connecting bag is hermetically installed on the outer side of the plastic bag, and each reaction cylinder is connected to a branch pipe at the bottom. The plurality of branch pipes communicate with a main pipe below.

[0009] In a further embodiment, the pressure rod and the reaction cylinder are in a sealed sliding structure, and the sawteeth of the pressure rod on the inner side of each reaction cylinder are arranged in an increasing manner.

[0010] In a further embodiment, the plastic bag is in a ring-shaped wavy shape, and the space between each group of wave crests is hermetically connected to the connecting bag to form a cavity. Baking soda is arranged inside the cavity of the plastic bag, and citric acid is arranged inside the cavity of the connecting bag.

[0011] In a further embodiment, a cavity is arranged inside the first protection part, and a second protection part is hermetically connected to the opening of the cavity. The elasticity of the first protection part is less than that of the second protection part.

[0012] In a further embodiment, the cavity is connected to the end of the main pipe.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] 1. In the present invention, an adjusting mechanism and a reaction mechanism are provided. When a diver dives, the underwater pressure will increase with the increase of depth. As the underwater pressure increases, the movable plate is squeezed and moves inward. The movement of the movable plate drives the pressure rod and the sawtooth to slide in the reaction cylinder, puncturing the plastic bag and the connecting bag. Baking soda and citric acid are mixed to generate carbon dioxide gas. The carbon dioxide gas enters the cavity inside the first protection part through the branch pipe and the main pipe. The pressure of the carbon dioxide gas causes the second protection part to expand. The expansion of the second protection part fills the gap between the mask and the face, and the underwater pressure cannot squeeze water into the mask through the gap. The diver's vision and breathing are not affected. Compared with the existing technology, in the present invention, through the adjusting mechanism and the reaction mechanism, the second protection part expands adaptively under the gradually increasing pressure, effectively filling the gap between the mask and the face, improving the sealing performance of the mask, thus ensuring the diver's vision and breathing. The expansion of the second protection part can also enhance the stability of the mask, making it fit more closely to the face, avoiding the mask from shifting or falling off due to changes in underwater pressure, and improving the safety of the diver.

[0015] 2. The present invention is provided with an adjusting mechanism and a reaction mechanism. When the diver continues to dive deeper, the underwater pressure further increases. The increase in underwater pressure causes the movable plate to move further inward. The further movement of the movable plate triggers the adjusting mechanism, which punctures new plastic bags and connecting bags to generate more carbon dioxide gas. The carbon dioxide gas enters the cavity inside the first protection part through the branch pipe and the main pipe. The pressure of the carbon dioxide gas causes the second protection part to expand further. The further expansion of the second protection part can better fill the gaps and resist greater underwater pressure, maintaining the sealing of the face mask. Compared with the existing technology, the present invention intermittently generates carbon dioxide gas through the cooperation of the adjusting mechanism and the reaction mechanism, causing the second protection part to expand further as the underwater pressure increases, thereby effectively maintaining the sealing of the face mask and ensuring the diver's vision and breathing.

[0016] 3. The present invention is provided with an adjusting mechanism. When the diver returns, the underwater pressure gradually decreases. As the underwater pressure decreases, the movable plate slowly moves outward under the elastic reset of the spring. The movement of the movable plate drives the pressure rod to move outward. The pressure rod cooperates with the reaction cylinder, the branch pipe, and the main pipe to suck out the carbon dioxide gas in the cavity. The reduction of the carbon dioxide gas causes the second protection part to gradually contract. The contraction of the second protection part can relieve the extrusion of the face mask on the face. Compared with the existing technology, the present invention makes the second protection part gradually contract as the underwater pressure decreases through the elastic reset of the spring and gas suction, thereby effectively relieving the extrusion of the face mask on the face and improving the comfort of the diver.

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0025] Please refer to Figures 1-6 An embodiment provided by the present invention: A diving mask for underwater detection includes a body 1. A connecting cylinder 2 is installed on the outer side of the upper jaw of the body 1, and a frame plate 3 is connected to the outer side of the connecting cylinder 2. A movable plate 4 is arranged above the frame plate 3. A plate member 6 is connected to the inner side of the connecting cylinder 2. A first protection part 8 is also attached to the inner surface of the body 1; It also includes an adjusting mechanism 5 and a reaction mechanism 7. The adjusting mechanism 5 cooperates with the reaction mechanism 7 to enable the diver to gradually increase the pressure during diving, so that the adjusting mechanism 5 adaptively triggers the reaction mechanism 7 to ensure the sealing between the body 1 and the diver's face.

[0026] Embodiment 1 Please refer to Figures 1-6, a support plate 301 is installed inside the frame plate 3, and a telescopic rod 302 is connected above the support plate 301. A spring 303 is clamped outside the telescopic rod 302. The adjusting mechanism 5 includes a pressure rod 501 connected to the bottom of the movable plate 4, and a sawtooth 502 is provided at the end of the pressure rod 501. A spiral groove 503 is also provided at the end of the pressure rod 501. The reaction mechanism 7 includes a plurality of reaction cylinders 701 connected to the inside of the plate member 6, and plastic bags 702 are correspondingly arranged on the inner walls of the plurality of reaction cylinders 701. A connecting bag 703 is hermetically installed outside the plastic bag 702, and each reaction cylinder 701 is connected to a sub-pipe 704 at the bottom. The plurality of sub-pipes 704 communicate with a main pipe 705 below. The pressure rod 501 and the reaction cylinder 701 are in a sealed sliding structure, and the sawteeth 502 of the pressure rod 501 inside each reaction cylinder 701 are arranged in an increasing manner. The plastic bag 702 is in a circular wave shape, and the space between each group of wave peaks is hermetically connected to the connecting bag 703 to form a cavity. Baking soda is provided inside the cavity of the plastic bag 702, and citric acid is provided inside the cavity of the connecting bag 703. A cavity 801 is provided inside the first protection part 8, and a second protection part 802 is hermetically connected to the opening of the cavity 801. The elasticity of the first protection part 8 is less than that of the second protection part 802. The cavity 801 is connected to the end of the main pipe 705;

[0027] Due to the slow increase in water pressure, not only is the mask body 1 of the diver squeezed, but also the movable plate 4 on the outer side of the head of the mask body 1 will have its extrusion force gradually increase under the same environment. As a result, the movable plate 4 will slowly move towards the mask body 1 under the sealed sliding of the frame plate 3 and the cooperation of the telescopic rod 302 and the spring 303, and at the same time, it will drive the pressure rod 501 and the serrations 502 to move in the same direction under the sealed sliding of the reaction cylinder 701. Thus, the first pressure rod 501 on the left side and the serrations 502 at its end will first puncture the plastic bag 702 and the connecting bag 703 inside the reaction cylinder 701. Since the diver's mask body 1 faces the bottom of the water when diving, the baking soda inside the plastic bag 702 and the citric acid inside the connecting bag 703 can simultaneously fall into the vortex groove 503 inside the pressure rod 501. Since the chemical name of baking soda is sodium bicarbonate NaHCO3, it reacts with citric acid C6H8O7 to produce sodium citrate Na3C6H5O7, carbon dioxide CO2, and water H2O. In this process, the carbon dioxide gas produced is non-toxic to the human body at normal concentrations. Thus, the carbon dioxide gas enters the cavity 801 inside the first protection part 8 through the through hole at the bottom of the reaction cylinder 701, the branch pipe 704, and the main pipe 705. Since the second protection part 802 is made of an elastic material, it can be squeezed and expand towards the face, thereby effectively compensating for the gap generated when the mask body 1 is squeezed by the pressure through the expansion of the second protection part 802, ensuring the sealing between the mask body 1 and the face, and at the same time preventing the safety hazard of water leakage caused by the increase in pressure on the mask body 1. The above is the state of the diver just entering the water.

[0028] Example 2 Please refer to Figure 3, different from the first embodiment: a support plate 301 is installed inside the frame plate 3, and a telescopic rod 302 is connected above the support plate 301. A spring 303 is clamped outside the telescopic rod 302. The adjusting mechanism 5 includes a pressure rod 501 connected to the bottom of the movable plate 4, and a sawtooth 502 is arranged at the end of the pressure rod 501. A spiral groove 503 is also arranged at the end of the pressure rod 501. The reaction mechanism 7 includes a plurality of reaction cylinders 701 connected to the inside of the plate member 6, and plastic bags 702 are correspondingly arranged on the inner walls of the plurality of reaction cylinders 701. A connecting bag 703 is hermetically installed outside the plastic bag 702, and a branch pipe 704 is connected to the bottom of each reaction cylinder 701. The plurality of branch pipes 704 communicate with the main pipe 705 below. The pressure rod 501 and the reaction cylinder 701 are in a sealed sliding structure, and the sawteeth 502 of the pressure rod 501 inside each reaction cylinder 701 are arranged in an increasing manner. The plastic bag 702 is in a ring-shaped wavy shape, and a cavity is formed by a sealed connection between each group of wave crests and the connecting bag 703. Baking soda is arranged inside the cavity of the plastic bag 702, and citric acid is arranged inside the cavity of the connecting bag 703. A cavity 801 is arranged inside the first protection part 8, and a second protection part 802 is hermetically connected to the opening of the cavity 801. The elasticity of the first protection part 8 is less than that of the second protection part 802. The cavity 801 is connected to the end of the main pipe 705;

[0029] As the diver continues to dive deeper, the pressure of the mask body 1 and the movable plate 4 in the water becomes greater and greater, and the squeezing force of the first protection part 8 and the second protection part 802 on the face also becomes greater and greater. To avoid the generation of new gaps at the squeezing and tearing part of the second protection part 802 on the face, in actual use, the movable plate 4 set in this application has a continuously increasing moving size as the pressure increases, so as to continuously drive the adjusting mechanism 5 to work. When the diver is diving downward and is in different pressure sections, the reaction mechanism 7 corresponding to different pressure sections will be intermittently triggered. Therefore, the carbon dioxide gas inside the cavity 801 can be intermittently increased, and then the expansion amount of the second protection part 802 can be increased. Therefore, it is avoided that when the diver is diving downward and the pressure is getting greater and greater, a safety hazard of water leakage will occur during the process of tearing between the first protection part 8 and the second protection part 802 of the mask body 1 and the face.

[0030] Embodiment Three Please refer to Figure 4, different from the second embodiment: a support plate 301 is installed inside the frame plate 3, and a telescopic rod 302 is connected above the support plate 301. A spring 303 is clamped outside the telescopic rod 302. The adjusting mechanism 5 includes a pressure rod 501 connected to the bottom of the movable plate 4, and a sawtooth 502 is provided at the end of the pressure rod 501. A scroll groove 503 is also provided at the end of the pressure rod 501. The reaction mechanism 7 includes a plurality of reaction cylinders 701 connected to the inside of the plate member 6, and plastic bags 702 are correspondingly arranged on the inner walls of the plurality of reaction cylinders 701. A connecting bag 703 is hermetically installed outside the plastic bag 702, and a branch pipe 704 is connected to the bottom of each reaction cylinder 701. The plurality of branch pipes 704 communicate with the main pipe 705 below. The pressure rod 501 and the reaction cylinder 701 are in a sealed sliding structure, and the sawteeth 502 of the pressure rod 501 inside each reaction cylinder 701 are arranged in an increasing manner. The plastic bag 702 is in a circular wave shape, and a cavity is formed by a sealed connection between each group of wave peaks and the connecting bag 703. Baking soda is provided inside the cavity of the plastic bag 702, and citric acid is provided inside the cavity of the connecting bag 703. A cavity 801 is provided inside the first protection part 8, and a second protection part 802 is hermetically connected to the opening of the cavity 801. The elasticity of the first protection part 8 is less than the elasticity of the second protection part 802. The cavity 801 is connected to the end of the main pipe 705;

[0031] When the diver returns, as the diver swims slowly upward, the pressure also gradually decreases. At this time, the mask body 1, the first protection part 8, and the second protection part 802 will gradually reduce the squeezing force on the face as the pressure decreases, and will also cause the first protection part 8 and the second protection part 802 to reduce the tearing of the diver's face;

[0032] Combined with the above principle, during the process of gradually decreasing pressure, the movable plate 4 will also move slowly outward under the elastic reset of the spring 303, driving the movable plate 4 and the adjusting mechanism 5 to move outward. At the same time, it will also drive the pressure rod 501 to move outward. The movement of the pressure rod 501 can cooperate with the reaction cylinder 701, the branch pipe 704, and the main pipe 705 to suck the carbon dioxide inside the cavity 801. Therefore, the expansion amount of the second protection part 802 is reduced, so that when the diver returns, the squeezing force of the mask body 1 on the face is slowly reduced, thereby reducing the discomfort caused by the squeezing of the mask body 1 on the face when the diver returns.

[0033] Working principle: As Figures 1-2 shown, before diving, the diver first buckles the mask body 1 on the face through the strap at the back and has it checked by a professional for the buckled mask body 1. After the check, the diver can go underwater for exploration.

[0034] The pressure of water is calculated by the formula p = ρgh, where ρ is the density of water, g is the acceleration due to gravity, and h is the water depth. Due to the relatively large density of water, when a diver jumps into the water and gradually dives downward, the pressure of water will also increase slowly.

[0035] Due to the slow increase in water pressure, the mask body 1 of the diver will also be squeezed accordingly. Subsequently, the first protection part 8 attached to the inner side of the mask body 1 on the diver's face will also be squeezed. At this time, there will be a phenomenon of tearing the facial skin on the diver's face, which will cause the face to become rather distorted. Moreover, with the synchronous movement of the facial skin and the first protection part 8, it is prone to breaking the original tightly sealed state and generating gaps under the action of different regions of facial bones, resulting in seal failure and affecting vision and breathing. To solve this problem, as follows:

[0036] Due to the slow increase in water pressure, not only is the mask body 1 of the diver squeezed, but also the movable plate 4 on the outer side of the head of the mask body 1 will have its extrusion force gradually increase in the same environment. As a result, the movable plate 4 will slowly move towards the mask body 1 under the combined action of the sealed sliding of the movable plate 4 in the frame plate 3, the telescopic rod 302, and the spring 303. At the same time, it will drive the pressure rod 501 and the sawtooth 502 to move in the same direction under the sealed sliding of the reaction cylinder 701. Thus, the first pressure rod 501 on the left side and the sawtooth 502 at its end will first pierce the plastic bag 702 and the connecting bag 703 inside the reaction cylinder 701. Since the diver is facing the bottom when diving, the baking soda inside the plastic bag 702 and the citric acid inside the connecting bag 703 can simultaneously fall into the spiral groove 503 inside the pressure rod 501. Since the chemical name of baking soda is sodium bicarbonate NaHCO₃, it reacts with citric acid C₆H₈O₇ to generate sodium citrate Na₃C₆H₅O₇, carbon dioxide CO₂, and water H₂O. In this process, the carbon dioxide gas generated is non-toxic to the human body at normal concentrations. Therefore, the carbon dioxide gas enters the cavity 801 inside the first protection part 8 through the through hole at the bottom of the reaction cylinder 701, the branch pipe 704, and the main pipe 705. Since the second protection part 802 is made of an elastic material, it can be squeezed and expand towards the face, thereby effectively compensating for the gap generated when the mask body 1 is squeezed by pressure through the expansion of the second protection part 802, ensuring the sealing between the mask body 1 and the face, and at the same time preventing the safety hazard of water leakage caused by the increase in pressure of the mask body 1. The above is the state of the diver just entering the water. For details, please refer to Figures 3-6 as shown.

[0037] As the diver continues to dive deeper, the pressure of the mask body 1 and the movable plate 4 in the water becomes greater and greater, and the squeezing force of the first protection part 8 and the second protection part 802 on the face also becomes greater and greater. To avoid the generation of new gaps at the squeezing and tearing part of the second protection part 802 on the face, in actual use, the movable plate 4 set in this application has a continuously increasing moving dimension as the pressure increases, which will continuously drive the adjusting mechanism 5 to work. When the diver is diving downward, at different pressure sections, the reaction mechanism 7 corresponding to different pressure sections will be intermittently triggered. Therefore, the amount of carbon dioxide gas inside the cavity 801 can be intermittently increased, and then the expansion amount of the second protection part 802 can be increased. Therefore, during the diver's downward dive, when the pressure is getting greater and greater, the potential safety hazard of water leakage caused by the tearing between the first protection part 8 and the second protection part 802 of the mask body 1 and the face is avoided. For details, please refer to Figure 3 。

[0038] When the diver returns, as the diver slowly swims upward, the pressure also slowly decreases. At this time, the mask body 1, the first protection part 8 and the second protection part 802 will gradually reduce the squeezing force on the face as the pressure decreases, and it will also make the first protection part 8 and the second protection part 802 reduce the tearing of the diver's face;

[0039] Combined with the above principle, during the process of gradually decreasing pressure, the movable plate 4 will also be slowly pushed outward by the elastic reset of the spring 303, driving the movable plate 4 and the adjusting mechanism 5 to move outward. At the same time, it will also drive the pressure rod 501 to move outward. The movement of the pressure rod 501 can cooperate with the reaction cylinder 701, the branch pipe 704 and the main pipe 705 to suck the carbon dioxide inside the cavity 801. Therefore, the expansion amount of the second protection part 802 is reduced, so that when the diver returns, the squeezing force of the mask body 1 on the face is slowly reduced, and then the discomfort caused by the squeezing of the mask body 1 on the face when the diver returns is reduced.
