DETAILED DESCRIPTION OF THE EMBODIMENTS
[0032] To make the objectives, technical solutions and advantages of the present utility model clearer, the technical solutions in the present utility model will be clearly and completely described below with reference to the accompanying drawings in the present utility model. Apparently, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present utility model without making creative efforts fall within the scope of protection of the present utility model.
[0033] The following Figures 1-3 describes the solid oxygen generator for individual combat of the present utility model.
[0034] Referring Figures 1 to 3 , according to the present utility model, a solid oxygen generator for individual combat is provided, which includes a housing 100, a gas delivery structure 200 and an isolation structure 300. The housing 100 is provided with a chamber. The gas delivery structure 200 is used for outputting oxygen. The gas delivery structure 200 is arranged at one end of the housing 100 and is communicated with the chamber. The isolation structure 300 is arranged inside the chamber. The isolation structure 300 is used for dividing the chamber into multiple regions and for blocking the heat transfer between two adjacent regions. Among them, each region is provided with a corresponding solid oxygen cartridge 400, and the housing 100 is provided with a plurality of mechanical ignition structures. The plurality of mechanical ignition structures correspond to the plurality of regions one by one, and the mechanical ignition structure cooperates with the corresponding solid oxygen cartridge 400 for ignition.
[0035] For the solid oxygen generator for individual combat provided by the present utility model, during operation, after the mechanical ignition structure is activated, a chemical reaction occurs to release heat by combustion, and then the solid oxygen cartridge 400 is ignited to release oxygen with ultra-high purity. Since each region has a corresponding solid oxygen cartridge 400 and a corresponding mechanical ignition structure, when the solid oxygen generator is damaged (for example: severely damaged by gunshots or metal fragment impacts), the surviving solid oxygen cartridges 400 can still function normally to supply oxygen. The mechanical ignition method has high reliability, can adapt to a wide range of working temperatures, and does not rely on batteries or other power sources. And by providing the isolation structure 300, the adjacent two solid oxygen cartridges 400 are separated, and at the same time, the mutual influence between the solid oxygen cartridges 400 due to heat transfer is avoided, improving the working stability and reliability of the solid oxygen generator. Moreover, the solid oxygen generator has a certain battlefield adaptability, can adapt to various terrain structures, environmental temperatures and battlefield conditions, which helps to improve the overall combat level of our army in the plateau area and has a positive significance for improving the military combat level.
[0036] It should be noted that in the embodiments of the present utility model, the above-mentioned housing 100 is made of metal, which is beneficial to providing a certain protective effect.
[0037] It can be understood that referring Figures 1 to 3, in the embodiment of the present utility model, an installation groove is provided at the upper end of the solid oxygen charge 400. The mechanical ignition structure includes a mechanical igniter 510, an ignition charge 520, and a transfer charge 530. The ignition charge 520 and the transfer charge 530 are sequentially arranged in the installation groove from top to bottom. The mechanical igniter 510 cooperates with the ignition charge 520 to ignite the ignition charge 520 and the transfer charge 530. With the above structure, the ignition charge 520 is triggered by the mechanical igniter 510, thereby igniting the transfer charge 530 to achieve the ignition of the solid oxygen charge 400. The ignition method is more reliable because it does not rely on electricity or other electronic components that may malfunction. Since both the ignition charge 520 and the transfer charge 530 are installed in the groove and the mechanical igniter 510 cooperates with the ignition charge 520, the ignition process will be faster and more effective, ensuring rapid ignition when needed and improving the utilization efficiency of the solid oxygen charge 400. The overall structure is more compact, which helps to reduce the volume and weight of the solid oxygen charge 400, while improving its portability and ease of carrying.
[0038] It can be understood that, in the embodiment of the present utility model, the isolation structure 300 includes a plurality of isolation grids 310. The plurality of isolation grids 310 are connected end to end to form a plurality of regions. Isolation grids 310 are provided between the inner wall of the housing 100 and the solid oxygen charge 400 and between two adjacent solid oxygen charges 400 to prevent heat loss and avoid mutual influence between the solid oxygen charges 400 due to heat transfer, thereby improving the working reliability of the solid oxygen generator.
[0039] Specifically, in the embodiment of the present utility model, the thickness of the above-mentioned isolation grid 310 is L1, and the value range of L1 is from 1 mm to 3 mm, with appropriate size and reasonable design. It should also be noted that the above-mentioned isolation member is a heat-insulating member made of heat-insulating material, which further prevents heat loss and improves the working reliability of the solid oxygen generator.
[0040] It can be understood that, with reference to Figures 1 to 3 , in the embodiment of the present utility model, a heat-insulating and heat-preserving layer 600 is provided in each region of the housing 100. The heat-insulating and heat-preserving layer 600 covers the outer wall of the solid oxygen charge 400, and the heat-insulating and heat-preserving layer 600 is located between the isolation grid 310 and the solid oxygen charge 400. Among them, the thickness of the heat-insulating and heat-preserving layer 600 is L2, and the value range of L2 is from 1.5 mm to 6 mm. With the above structure, it is beneficial to prevent ignition failure, flameout, or oxygen supply interruption caused by too fast heat loss in the extreme low-temperature environment in plateau areas, and improves the working reliability of the solid oxygen generator.
[0041] Specifically, in the embodiment of the present utility model, a fixing structure is provided on the outer wall of the housing 100, and the fixing structure is used to install the solid oxygen generator to the installation position. It can be understood that in this embodiment, the solid oxygen generator is installed at the corresponding position of the user through the fixing structure, for example: installed on the soldier's shoulder, thigh or chest. It should be noted that the above fixing structure is a Velcro, and multiple solid oxygen generators can be distributed and pasted on the shoulder, thigh or chest, which is very convenient to carry. During the movement of the soldier, it will not swing left and right or up and down, affecting the stability of the soldier's body center of gravity, and the distributed carrying can provide backup capabilities and high battlefield adaptability. Of course, in some embodiments, the above fixing structure can also be a locking hoop or other structures, which are not limited herein.
[0042] It can also be understood that, referring to Figure 1 and Figure 2 , in the embodiment of the present utility model, a first heat insulation cotton layer 710 and a second heat insulation cotton layer 720 are provided in each area of the housing 100, and the first heat insulation cotton layer 710 and the second heat insulation cotton layer 720 are distributed on the upper and lower sides of the solid oxygen medicine column 400.
[0043] With the above structure, the first heat insulation cotton layer 710 and the second heat insulation cotton layer 720 can effectively isolate the high temperature inside the solid oxygen medicine column 400, prevent the influence of the external environment on the solid oxygen medicine column 400, provide more comprehensive heat insulation protection, and the presence of the first heat insulation cotton layer 710 and the second heat insulation cotton layer 720 can help control the temperature distribution of the solid oxygen medicine column 400. By adjusting the materials and thicknesses of the first heat insulation cotton layer 710 and the second heat insulation cotton layer 720, the temperature of the solid oxygen medicine column 400 can be effectively controlled to ensure its operation within the appropriate working temperature range, reduce the temperature on the surface of the shell of the solid oxygen medicine column 400, and reduce the risk of scalding when touched accidentally. The key components and materials inside the solid oxygen medicine column 400 can avoid being damaged by high temperature, thereby prolonging the service life of the solid oxygen medicine column 400 and reducing the maintenance and replacement costs. It should be noted that the oxygen filters out toxic dust after flowing through the heat insulation layer 600, the first heat insulation cotton layer 710 and the second heat insulation cotton layer 720.
[0044] Specifically, referring to Figure 1 and Figure 2, in the embodiment of the present utility model, a Hopcalite agent layer 810 and a microfiltration membrane layer 820 are provided in each area of the housing 100. The Hopcalite agent layer 810 and the microfiltration membrane layer 820 are sequentially arranged between the lower side of the second heat insulation cotton layer 720 and the upper side of the gas transmission structure 200 from top to bottom. With the above structure, toxic and harmful gases such as carbon oxide gas and chlorine gas are filtered by the Hopcalite agent layer 810, and then part of the dust from the Hopcalite agent layer 810 is further filtered by the microfiltration membrane layer 820, which is beneficial to making the remaining gas be medical oxygen with a purity of 99.55%. The remaining gas is collected at the gas transmission structure 200. The above design can effectively improve the gas purification effect of the solid oxygen cartridge 400, protect the equipment, improve the oxygen output quality, and thus better meet various application requirements.
[0045] Specifically, in the embodiment of the present utility model, the solid oxygen cartridge 400 is a sodium chlorate solid oxygen product. With the above setting, the chemical oxygen generation technology based on the sodium chlorate-based solid oxygen source is beneficial to solving the problems of the weight, volume, oxygen purity and working time of the individual oxygen supply equipment. It can be understood that the oxygen storage density of sodium chlorate solid oxygen is close to that of liquid oxygen, which is 3 times that of compressed oxygen, and the oxygen concentration released by thermal decomposition is usually higher than 99.5%. It has the advantages of light weight, small volume, high oxygen purity and long working time.
[0046] Specifically, in this embodiment, the solid oxygen cartridge 400 includes a sodium chlorate oxygen generating agent, a potassium perchlorate stabilizer, a cobalt sesquioxide catalyst and an inorganic binder. Among them, the content ratio of each component is: the sodium chlorate oxygen generating agent is 90-95%, the potassium perchlorate stabilizer is 1-5%, the cobalt sesquioxide catalyst is 1-5%, and the inorganic binder is 0.1-2%. And the density of the solid oxygen cartridge 400 is ρ, and the value range of ρ is 1.9-2.3 g / cm3.
[0047] With the above structure, the solid oxygen generator with the solid oxygen cartridge 400 being a sodium chlorate solid oxygen product can withstand high temperature and mechanical shock. The oxygen generation process is close to normal pressure, and it is beneficial to reduce the working noise that affects concealment. It has excellent battlefield adaptability and high safety. Each solid oxygen generator is small in volume and light in weight, which is conducive to realizing distributed carrying and has a high backup capacity, further improving the working reliability in the battlefield environment.
[0048] It should be noted that, referring to Figure 1 and Figure 2, in the embodiment of the present utility model, a powder raw material with a suitable particle size is selected. After being uniformly mixed, it is pressed into a cuboid-shaped solid oxygen medicine column 400 by a press under a certain pressure. The above-mentioned solid oxygen generator has a cuboid shape, with a single weight of about 200 grams, a size of 8mm×4mm×15mm, which is larger than an ordinary cigarette case. The oxygen supply time is about 1 hour. A single soldier can carry at least 6 of them, and the total oxygen supply time is not less than 6 hours, which is beneficial to meeting the needs of soldiers in field operations and patrols. It has the advantages of light weight, small volume, long working time, and safety and reliability.
[0049] It can be understood that, referring to Figure 1 and Figure 2 , in the embodiment of the present utility model, the gas transmission structure 200 includes a gas storage chamber 210, a gas collecting pipe 220, and an oxygen delivery pipe 230. The intake side of the gas storage chamber 210 is communicated with the interior of the chamber to collect the oxygen generated by a plurality of solid oxygen medicine columns 400. The intake end of the gas collecting pipe 220 is communicated with the outlet side of the gas storage chamber 210, and one end of the oxygen delivery pipe 230 is communicated with the outlet end of the gas collecting pipe 220.
[0050] With the above structure, the intake side of the gas storage chamber 210 being communicated with the interior of the chamber means that the oxygen generated by a plurality of solid oxygen medicine columns 400 can be collected from the chamber. By concentrating and collecting the oxygen in the gas storage chamber 210, the oxygen can be managed and utilized more effectively. The intake end of the gas collecting pipe 220 being communicated with the outlet side of the gas storage chamber 210 means that it receives the oxygen from the gas storage chamber 210. The gas collecting pipe 220 is responsible for transporting the oxygen from the gas storage chamber 210 to the oxygen delivery pipe 230 for further delivery to the location where oxygen is needed.
[0051] It should be noted that, in this embodiment, the cross-sectional area of the above-mentioned gas storage chamber 210 is adapted to the cross-sectional area of the housing 100 to facilitate the collection of the oxygen generated by the solid oxygen medicine column 400.
[0052] It can be understood that in the embodiments of the present utility model, when soldiers are performing patrol, military exercise or combat tasks, they carry several solid oxygen generators with them and hang them on the shoulders, thighs and chests using Velcro. In case of an emergency oxygen deficiency situation, one of the mechanical igniters 510 of the several solid oxygen generators carried with them is pulled out, and the ignition powder 520 sensitive to flame immediately burns, with an instantaneous temperature reaching over 1000 °C, igniting the transfer powder 530 with high energy density. Under the continuous heating of the transfer powder 530, the solid oxygen medicine column 400 is thermally decomposed within 3 to 5 seconds to release high-purity oxygen. The oxygen filters out toxic dust after flowing through the heat insulation layer 600, the first heat insulation cotton layer 710 and the second heat insulation cotton layer 720, filters out toxic and harmful gases such as carbon oxide gas and chlorine through the Hopcalite layer 810, and further filters out some dust from the Hopcalite layer 810 through the microfiltration membrane layer 820. The remaining gas is medical oxygen with a purity of 99.55%, which is collected in the oxygen storage bin and then sent to the mouth and nose through the gas collecting pipe 220 and the oxygen delivery pipe 230. It can be understood that the surface temperature of the solid oxygen generator can be controlled within the range of 35 to 50 °C, which can play a certain role in keeping warm in high-altitude areas. In case of an emergency war situation, the solid oxygen generator module can also play a certain role in protecting the human body. When the solid oxygen generator housing 100 and most of the solid oxygen medicine columns 400 inside are severely damaged, the mechanical igniters 510 of the remaining solid oxygen medicine columns 400 are pulled out to supply oxygen; when the entire solid oxygen generator is damaged, the solid oxygen generators hung on other parts of the body are used to supply oxygen.
[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model and are not intended to limit them; although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present utility model.
