Description

Technical Field

[0001] The utility model belongs to the technical field of submersible masks, and relates to a mask simulating the background of ocean thermal infrared radiation. Background Art

[0002] According to the data of the National Oceanic and Atmospheric Administration of the United States, as of 2021, the average global ocean surface temperature was 15.4 °C, while the human body has a constant temperature, generally around 37 °C. Therefore, there is a significant temperature difference between the human body and the ocean.

[0003] When a diver dives from the seabed to collect information, it is usually necessary for the diver to protrude the head from the sea water. At this time, the diver's head will completely leave the water surface. Since the temperature of the human head is higher than that of the sea water, the surface temperature of the head of the diving suit exposed above the water surface is significantly higher than the surrounding ocean temperature. Since the commonly used diving suits at present do not have infrared hiding performance, mainly because in infrared detection instruments, the sea water with a lower surrounding temperature will appear as dark spots, while the head of the diver wearing a diving suit with a higher temperature will appear as bright spots, making it extremely easy for divers to be detected by infrared detection instruments, increasing the exposure risk and thus leading to the failure of the collection task. Therefore, there is an urgent need for a mask that can simulate the background of ocean thermal infrared radiation, so that the infrared radiation characteristics of the diver's head after leaving the sea water are similar to those of the sea water infrared radiation, and it can meet a certain sense of spatial structure and wearing comfort.

[0004] In view of this, the present utility model is specifically proposed. Content of the Utility Model

[0005] The purpose of the present utility model is to overcome the above-mentioned disadvantages of the prior art, provide a mask simulating the background of ocean thermal infrared radiation, solve the problem of easy infrared exposure of the existing head diving suits, make the infrared radiation characteristics of the diver's head after leaving the sea water similar to those of the sea water infrared radiation, achieve a good infrared hiding effect, and have good elasticity and softness, achieving a comfortable wearing effect.

[0006] To achieve the above-mentioned purpose of the function, the present utility model provides the following technical solutions:

[0007] A mask simulating the background of ocean thermal infrared radiation, comprising: a mask body and accommodation holes provided at positions corresponding to the eyes of the wearer on the mask body; the mask body is a double-layer structure, including a heat-insulating layer and a low-emissivity surface layer arranged in sequence from the inside to the outside, a through hole is provided at a position corresponding to the mouth of the wearer on the mask body, and the accommodation holes are used for accommodating diving goggles.

[0008] Furthermore, a circular telescopic member is further provided on the mask body, and the circular telescopic member is connected to the hole wall of the accommodation hole for adjusting the aperture size of the accommodation hole.

[0009] Further, the annular telescopic member is fixedly connected to the hole wall of the accommodating hole by means of edge sewing.

[0010] Further, the low-emissivity surface layer is made of neoprene fabric treated with black chromium plating.

[0011] Further, the emissivity of the low-emissivity surface layer < 0.07.

[0012] Further, the hole wall of the through hole is subjected to edge sealing treatment.

[0013] Further, the heat insulation layer is made of fiber heat insulation fabric.

[0014] Further, the shape of the accommodating hole is the same as the shape of the diving mask it accommodates.

[0015] Compared with the prior art, the technical solution provided by the present utility model has the following beneficial effects:

[0016] 1. For the mask simulating the marine thermal infrared radiation background of the present utility model, according to the Stefan-Boltzmann law, the infrared radiation emitted by an object is proportional to its own emissivity and to the fourth power of its surface absolute temperature. In the mask of the present invention, the heat insulation layer is made of heat insulation materials, which can block the heat of the investigator from being conducted to the diving suit. Thus, when the wearer's head protrudes out of the water surface, the temperature of the head part of the diving suit can be reduced. The low-emissivity surface layer is made of neoprene fabric with black chromium plating on the surface. The black chromium coating has an extremely low emissivity at normal temperature, which can effectively interfere with infrared thermal imaging reconnaissance. Moreover, the low-emissivity surface layer with black chromium plating is black in color, which has good deception visually. Therefore, through the combined action of the low-emissivity surface layer and the heat insulation layer, the thermal radiation energy of the human head can be further reduced, making the infrared radiation characteristics of the wearer's head similar to the infrared radiation background of the sea water, achieving the effect of infrared camouflage or concealment.

[0017] 2. For the mask simulating the marine thermal infrared radiation background of the present utility model, the aperture of the accommodating hole can be adjusted by the annular telescopic member to accommodate diving masks of different sizes; and both the heat insulation layer and the low-emissivity surface layer have good elasticity and can adapt to the head sizes of different wearers. Therefore, the provided camouflage mask has general applicability. Description of the Drawings

When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. On the contrary, they are only examples consistent with some aspects of the present invention detailed in the appended claims.

[0024] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below with reference to the drawings and embodiments.

[0025] See Figures 1-2 As shown, this embodiment provides a face mask that simulates the background of ocean thermal infrared radiation. The face mask is sleeved on the head of a person wearing a diving suit and includes: a face mask body 1 and an accommodating hole 2 provided at a position corresponding to the eyes of the wearer on the face mask body 1; the face mask body 1 is a double-layer structure, including a thermal insulation layer 4 and a low emissivity surface layer 5 arranged in sequence from the inside to the outside. A through hole 3 is provided at a position corresponding to the mouth of the wearer on the face mask body 1, and the accommodating hole 2 is used to accommodate diving goggles.

[0026] According to an embodiment of the present utility model, the accommodation hole 2 is a through hole for accommodating the diving goggles worn by the wearer. The size and shape of the accommodation hole 2 can be set according to the size and shape of the diving goggles. For example, when the accommodation hole 2 is a square hole, since the diving goggles are usually approximately square, the square accommodation hole 2 can more conveniently accommodate the diving goggles. Moreover, in order to enable the accommodation hole 2 to adapt to diving goggles of different sizes, an annular telescopic member 6 is fixedly connected to the hole wall of the accommodation hole 2, and the annular telescopic member 6 is used to adjust the aperture of the accommodation hole 2. In this way, after the diving goggles are located in the accommodation hole 2, the annular telescopic member 6 will adjust the aperture of the accommodation hole 2 according to the diving goggles accommodated therein, so that the edge of the accommodation hole 2 tightly fits on the edge of the diving goggles, making there no gap between the accommodation hole 2 and the diving goggles, and avoiding seawater from flowing in through the gap between the accommodation hole 2 and the diving goggles when the wearer is moving in the seawater, thus improving the comfort of the wearer.

[0027] According to an embodiment of the present utility model, for the sake of aesthetics, the annular telescopic member 6 and the hole wall of the accommodation hole 2 are fixedly connected by means of edge sewing.

[0028] According to an embodiment of the present utility model, a through hole 3 is provided at a position corresponding to the mouth of the wearer on the mask body 1, and the aperture of the through hole 3 can be set according to the use requirements, as long as it does not affect the wearer's wearing of the breathing tube. For the sake of aesthetics, the hole wall of the through hole 3 and the mask body 1 are subjected to edge sealing treatment.

[0029] According to an embodiment of the present utility model, the low emissivity surface layer 4 is a neoprene fabric treated by black chromium plating with an emissivity < 0.07. The neoprene fabric has excellent elasticity and good water isolation property, and also has a relatively low emissivity after being treated by black chromium plating. The heat insulation layer 5 is a fiber heat insulation fabric, which has good waterproof, heat insulation and heat preservation properties, and also has good elasticity and softness. Therefore, after the low emissivity surface layer 4 and the heat insulation layer 5 are stacked, it can not only meet the wearer's latent in the ocean, but also perform thermal infrared camouflage on the wearer's head after the wearer's head protrudes from the ocean, and it is also relatively comfortable to wear.

[0030] The mask provided by the present utility model for simulating the thermal infrared radiation background of the ocean can effectively prevent the exposure of the infrared characteristics of the wearer, and has the characteristics of convenient wearability and strong applicability.

[0031] The above are only the specific embodiments of the present utility model, which enable those skilled in the art to understand or implement the present utility model. Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present utility model.

[0032] It should be understood that the present utility model is not limited to the above-described content and various modifications and changes can be made without departing from its scope. The scope of the present utility model is only limited by the appended claims.
