Description

Technical Field

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

[0002] Although the first protective part of the diving mask that contacts the human face is made of flexible material, in order to ensure stability, the flexible first protective part still needs to have a certain rigidity to avoid water leakage. At the same time, the back of the mask is fastened by straps, thus forming a waterproof space on the face.

[0003] However, when diving, since the underwater pressure gradually changes with the 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, and there will be a certain feeling that the mask is getting tighter and tighter. In addition to the bones, the human face also has the epidermis and soft tissue on the outer surface. When the mask pressure increases, the first protective part of the mask will be pressed against the epidermis and remain relatively still, but the facial skin is soft and will move. Therefore, when the water pressure increases, the mask will have a tearing action on the human face, causing the human face to become more abstract, and as the facial skin and the first protective part 8 move synchronously, the original close sealing state is easily broken by the action of the facial bones in different areas, resulting in 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, so as to solve the problem proposed in the above background technology that the underwater pressure increases with the increase of depth, resulting in the increase of the squeezing force of the mask on the face, the sealing state between the mask and the face is destroyed, and gaps are easily generated, resulting in water leakage, affecting the field of vision and breathing. The technical solution of the present invention is aimed at the technical problem that the existing technical solutions are too single, and provides a solution that is significantly different from the existing technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a diving mask for underwater detection, comprising a main body, a connecting tube installed on the outer side of the upper jaw of the main body, and a frame plate connected to the outer side of the connecting tube, a movable plate is arranged above the frame plate, a plate is connected to the inner side of the connecting tube, and a first protective part is also attached to the inner side of the main body; it also includes an adjusting mechanism and a reaction mechanism, the adjusting mechanism cooperates with the reaction mechanism, and is used for the diver to gradually increase the pressure during the diving process, so that the adjusting mechanism adaptively triggers the reaction mechanism to ensure the sealing between the main body and the diver's face.

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

[0007] In a further embodiment, the adjustment mechanism includes a pressure rod connected to the bottom of the movable plate, and the end of the pressure rod is provided with saw teeth, and the end of the pressure rod is also provided with a vortex groove.

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

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

[0010] In a further embodiment, the plastic bag is annularly wavy, and each group of wave peaks is sealed and 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 provided inside the first protecting portion, and the second protecting portion is sealed and connected to the opening of the cavity, and the elasticity of the first protecting portion is smaller than the elasticity of the second protecting portion.

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

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The present invention is provided with a regulating mechanism and a reaction mechanism. When a diver dives, the underwater pressure increases 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 tube, puncturing the plastic bag and the connecting bag. The baking soda and citric acid are mixed to generate carbon dioxide gas. The carbon dioxide gas enters the cavity in 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. The underwater pressure cannot squeeze water into the mask through the gap, and the diver's field of vision and breathing are not affected. Compared with the existing technology, the present invention uses an adjustment mechanism and a reaction mechanism to enable the second protection part to adaptively expand under the gradually increasing pressure, effectively filling the gap between the mask and the face, improving the sealing of the mask, thereby ensuring the diver's field of vision and breathing. The expansion of the second protection part can also enhance the stability of the mask, making it fit the face more closely, avoiding the displacement or falling off of the mask 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, 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. The adjusting mechanism punctures the new plastic bag and the connecting bag to produce more carbon dioxide gas. The carbon dioxide gas enters the cavity in 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 further expand. The further expansion of the second protection part can better fill the gap, resist greater underwater pressure, and maintain the sealing of the mask. Compared with the existing technology, the present invention intermittently produces carbon dioxide gas through the adjusting mechanism and the reaction mechanism, so that the second protection part further expands with the increase of underwater pressure, thereby effectively maintaining the sealing of the mask and ensuring the diver's field of vision and breathing.

[0016] 3. The present invention is provided with an adjustment 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 the carbon dioxide gas in the cavity. The reduction of carbon dioxide gas causes the second protective part to gradually shrink. The shrinkage of the second protective part can relieve the squeezing of the mask on the face. Compared with the existing technology, the present invention uses the elastic reset of the spring and gas suction to make the second protective part gradually shrink as the underwater pressure decreases, thereby effectively relieving the squeezing of the mask on the face and improving the comfort of the diver.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0025] See also Figure 1-6 An embodiment of the present invention is a diving mask for underwater detection, comprising a main body 1, a connecting tube 2 is installed on the outer side of the upper jaw of the main body 1, and a frame plate 3 is connected to the outer side of the connecting tube 2, a movable plate 4 is arranged above the frame plate 3, a plate 6 is connected to the inner side of the connecting tube 2, and a first protective portion 8 is also attached to the inner side of the main body 1; it also includes an adjusting mechanism 5 and a reaction mechanism 7, and the adjusting mechanism 5 cooperates with the reaction mechanism 7, and is used for the diver to gradually increase the pressure during the diving process, so that the adjusting mechanism 5 adaptively triggers the reaction mechanism 7 to ensure the sealing between the main body 1 and the diver's face.

[0026] Example 1 Please refer to Figure 1-6A support plate 301 is installed on the inner side of the frame plate 3, and a telescopic rod 302 is connected to the top of the support plate 301, and a spring 303 is clamped on the outer side of the telescopic rod 302. The adjustment 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, and a vortex 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 inner side of the plate 6, and the inner walls of the plurality of reaction cylinders 701 are correspondingly provided with plastic bags 702, and a connecting bag 703 is sealed and installed on the outer side of the plastic bag 702, and each reaction cylinder 701 is connected to a branch pipe 704 at the bottom, and the plurality of branch pipes 704 are connected to the bottom. The main pipe 705, the pressure rod 501 and the reaction cylinder 701 are in a sealed sliding structure, and the saw teeth 502 of the pressure rod 501 inside each reaction cylinder 701 are arranged in an increasing manner, the plastic bag 702 is annular and wavy, and each group of wave peaks is sealed and connected with the connecting bag 703 to form a cavity, baking soda is arranged inside the cavity of the plastic bag 702, citric acid is arranged inside the cavity of the connecting bag 703, a cavity 801 is arranged inside the first protection part 8, and the opening of the cavity 801 is sealed and connected with the second protection part 802, the elasticity of the first protection part 8 is less than the elasticity of the second protection part 802, and the cavity 801 is connected to the end of the main pipe 705;

[0027] As the water pressure increases slowly, not only the mask body 1 of the diver is squeezed, but also the extrusion force of the movable plate 4 outside the head of the mask body 1 will slowly increase under the same environment, so that the movable plate 4 will slowly move toward the mask body 1 under the sealing 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 sawtooth 502 to move in the same direction under the sealing sliding of the reaction cylinder 701, so that the first pressure rod 501 on the left and the sawtooth 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 is facing 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 fall into the inner side of the vortex groove 503 inside the pressure rod 501 at the same time. Since the chemical name of baking soda is sodium bicarbonate NaHCO 3 , which is combined with citric acid C 6 H 8 O 7 The reaction produces sodium citrate Na 3 C 6 H 5 O 7 、Carbon dioxide CO 2 and water 2O. In this process, the carbon dioxide gas produced is non-toxic to the human body at normal concentrations, so that the carbon dioxide gas enters into 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 elastic material, it can squeeze the second protection part 802 and expand toward the face, thereby effectively compensating for the interval caused by the pressure squeezing of the mask body 1 through the expansion of the second protection part 802, thereby ensuring the sealing between the mask body 1 and the face, and at the same time preventing the mask body 1 from leaking due to the increase in pressure. The above is the state of the diver just entering the water.

[0028] Example 2 Please refer to Figure 3 , which is different from the first embodiment, is that: a support plate 301 is installed on the inner side of the frame plate 3, and a telescopic rod 302 is connected to the top of the support plate 301, and a spring 303 is clamped on the outer side of the telescopic rod 302, the adjustment 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, and a vortex 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 inner side of the plate 6, and plastic bags 702 are correspondingly provided on the inner walls of the plurality of reaction cylinders 701, and a connecting bag 703 is sealed and installed on the outer side of the plastic bag 702, and a branch pipe 704 is connected to the bottom of each reaction cylinder 701, and the plurality of branch pipes 704 The main pipe 705 is connected to the bottom, the pressure rod 501 and the reaction cylinder 701 are in a sealed sliding structure, and the saw teeth 502 of the pressure rod 501 inside each reaction cylinder 701 are arranged in an increasing manner, the plastic bag 702 is annular and wavy, and each group of wave peaks is sealed and connected to the connecting bag 703 to form a cavity, baking soda is arranged inside the cavity of the plastic bag 702, citric acid is arranged inside the cavity of the connecting bag 703, a cavity 801 is arranged inside the first protection part 8, and the opening of the cavity 801 is sealed and connected to the second protection part 802, the elasticity of the first protection part 8 is less than the elasticity of the second protection part 802, and the cavity 801 is connected to the end of the main pipe 705;

[0029] As the diver continues to dive downward, 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 protective part 8 and the second protective part 802 on the face also becomes greater and greater. In order to avoid the second protective part 802 from creating a new gap at the place where the face is squeezed and torn, in actual use, the movable plate 4 provided in the present application continues to increase in movement size as the pressure increases, thereby continuously driving the adjustment mechanism 5 to work. When the diver is in different pressure segments during the diving process, the reaction mechanism 7 corresponding to the different pressure segments will be intermittently triggered, so that the carbon dioxide gas inside the cavity 801 can be intermittently increased, thereby increasing the expansion amount of the second protective part 802. Therefore, the safety hazard of water leakage caused by the first protective part 8 and the second protective part 802 of the mask body 1 tearing off the face is avoided when the pressure becomes greater and greater during the diving process.

[0030] Example 3, please refer to Figure 4 , which is different from the second embodiment, is that: a support plate 301 is installed on the inner side of the frame plate 3, and a telescopic rod 302 is connected to the top of the support plate 301, and a spring 303 is clamped on the outer side of the telescopic rod 302, the adjustment 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, and a vortex 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 inner side of the plate 6, and plastic bags 702 are correspondingly provided on the inner walls of the plurality of reaction cylinders 701, and a connecting bag 703 is sealed and installed on the outer side of the plastic bag 702, and a branch pipe 704 is connected to the bottom of each reaction cylinder 701, and the plurality of branch pipes 704 The main pipe 705 is connected to the bottom, the pressure rod 501 and the reaction cylinder 701 are in a sealed sliding structure, and the saw teeth 502 of the pressure rod 501 inside each reaction cylinder 701 are arranged in an increasing manner, the plastic bag 702 is annular and wavy, and each group of wave peaks is sealed and connected to the connecting bag 703 to form a cavity, baking soda is arranged inside the cavity of the plastic bag 702, citric acid is arranged inside the cavity of the connecting bag 703, a cavity 801 is arranged inside the first protection part 8, and the opening of the cavity 801 is sealed and connected to the second protection part 802, the elasticity of the first protection part 8 is less than the elasticity of the second protection part 802, and the cavity 801 is connected to the end of the main pipe 705;

[0031] When the diver returns, as the diver slowly swims upward, the pressure 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 the first protection part 8 and the second protection part 802 will also reduce the tearing of the diver's face;

[0032] Combined with the above principle, as the pressure of the movable plate 4 gradually decreases, the movable plate 4 and the adjustment mechanism 5 will be slowly pushed outward during the elastic reset of the spring 303, and the pressure rod 501 will also be driven 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 absorb the carbon dioxide inside the cavity 801, thereby reducing the expansion of the second protective part 802, so that the diver's mask body 1 can slowly reduce the squeezing force on the face of the diver when returning, thereby reducing the discomfort caused by the mask body 1 squeezing the face of the diver when returning.

[0033] Working principle: Figure 1-2 As shown, before diving, the diver first buckles the mask body 1 on the face through the straps at the back, and has the buckled mask body 1 inspected by professionals, and then can go into the water for detection.

[0034] The water pressure 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. Since the density of water is relatively large, when a diver jumps into the water and gradually dives downward, the water pressure will slowly increase.

[0035] As the water pressure gradually increases, the mask body 1 of the diver will also be squeezed, and then the first protective part 8 attached to the inner side of the mask body 1 of the diver's face will also be squeezed. At this time, the diver's face will be torn, which will make the face look more abstract. Moreover, as the face skin and the first protective part 8 move synchronously, the original close sealing state is easily broken by the action of the facial bones in different areas, resulting in gaps, causing sealing failure, affecting vision and breathing. To solve this problem, the following are made:

[0036] As the water pressure increases slowly, not only the mask body 1 of the diver is squeezed, but also the extrusion force of the movable plate 4 outside the head of the mask body 1 will slowly increase under the same environment, so that the movable plate 4 will slowly move toward the mask body 1 under the sealing 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 sawtooth 502 to move in the same direction under the sealing sliding of the reaction cylinder 701, so that the first pressure rod 501 on the left and the sawtooth 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 is facing 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 fall into the inner side of the vortex groove 503 inside the pressure rod 501 at the same time. Since the chemical name of baking soda is sodium bicarbonate NaHCO 3 , which is combined with citric acid C 6 H 8 O 7The reaction produces sodium citrate Na 3 C 6 H 5 O 7 、Carbon dioxide CO 2 and water 2 O, in this process, the carbon dioxide gas produced is non-toxic to the human body at normal concentrations, so that 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 elastic material, it can squeeze the second protection part 802 and expand toward the face, thereby effectively compensating the interval 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 mask body 1 from leaking due to the increase in pressure. The above is the state of the diver just entering the water. For details, please refer to Figure 3-6 shown.

[0037] As the diver continues to dive downward, 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 protecting part 8 and the second protecting part 802 on the face also becomes greater and greater. In order to prevent the second protecting part 802 from creating new gaps at the place where the face is squeezed and torn, in actual use, the movable plate 4 provided in the present application continues to increase in movement size as the pressure increases, thereby continuously driving the adjustment mechanism 5 to work. When the diver is in different pressure segments during the diving process, the reaction mechanism 7 corresponding to the different pressure segments will be triggered intermittently, so that the carbon dioxide gas inside the cavity 801 can be intermittently increased, thereby increasing the expansion amount of the second protecting part 802. Therefore, the safety hazard of water leakage caused by the increasing pressure during the diving process of the diver is avoided, which may cause the first protecting part 8 and the second protecting part 802 of the mask body 1 to tear off from the face. For details, please refer to Figure 3 .

[0038] When the diver returns, as the diver slowly swims upward, the pressure 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 the first protection part 8 and the second protection part 802 will also reduce the tearing of the diver's face;

[0039] Combined with the above principle, as the pressure of the movable plate 4 gradually decreases, the movable plate 4 and the adjustment mechanism 5 will be slowly pushed outward during the elastic reset of the spring 303, and the pressure rod 501 will also be driven 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 absorb the carbon dioxide inside the cavity 801, thereby reducing the expansion of the second protective part 802, so that the diver's mask body 1 can slowly reduce the squeezing force on the face of the diver when returning, thereby reducing the discomfort caused by the mask body 1 squeezing the face of the diver when returning.
