The whole system is completely closed and is waterproof under the normal state, the internal components are all in a sealing state, and the internal parts contacted with sodium hydroxide are all strong alkali resistant.
The working process of the invention is as follows:
and in the first step, the spring-up mechanism is triggered to feed water when opened. When the user encounters a danger in water, the upper dial 6 is opened after the trigger spring mechanism 12 is pressed (the opening mode is selected according to the requirement, for example, the upper dial is turned to one side through a hinge or the whole is fallen off), the compressed air bag 11 begins to expand, the spring 9 springs upwards, the compressed hot melt film 10 is carried up, a reaction container slightly higher than the height of the wristwatch body is formed inside the wristwatch by the spring 9 and the hot melt film 10, and the design is used for providing enough reaction raw materials and solvents for the reaction of aluminum and sodium hydroxide. The lower watch seat 13 is separated from the upper watch case 5 while the trigger spring mechanism 12 is pressed down, and the connecting rope 14 coiled in the wristwatch is torn off, so that the design is used for preventing the reaction heat release moment from being slightly higher in temperature and possibly causing scalding; at this time, water enters the bladder 11 through the fluid passage 522, and as the water inflow increases, the water level at the bottom of the bladder increases gradually and does not form the upper end of the reaction vessel of the hot melt film 10.
When water in the wrist surface starts to flow into the reaction container formed by the hot melt film 10, sodium hydroxide is dissolved in the water and the sodium hydroxide reacts with metal aluminum to release heat, so that the heat-sensitive metal sheet 4 is heated to deform to close the upper check valve 3, the closed fluid channel 522 is not filled with water, meanwhile, the metal sheet is separated from the bottom of the spring due to the deformation of the heat-sensitive metal sheet 4, the bottom channel flows in water, the reaction rate is increased, and the heat generated in the moment in the reaction stage can dissolve the hot melt film 10 to increase the reaction rate, so that the gas production rate is accelerated. Splash can be generated at the beginning of the reaction, and the splash-proof filter screen 7 is specially designed for preventing the splash, so that the reaction raw materials are prevented from being sprayed away, and the final reduction of gas yield is avoided. The splash-proof filter screen 7 is made of aluminum, and can still react with excessive sodium hydroxide slowly to generate hydrogen when the reaction approaches to tail sound, so that the stability of the pressure in the air bag is ensured, and the closing state of the upper check valve and the lower check valve is further ensured. The principle of this reaction is that aluminum reacts with aqueous sodium hydroxide to produce hydrogen and sodium metaaluminate, which react spontaneously with concomitant exotherm.
Before use, the color of the air bag is observed from the observation port 8, if the air bag changes color, the chemical components in the wristwatch are proved to be invalid and cannot be used, in addition, the wristwatch can be shaken by hands under normal use state by controlling the filling amount of aluminum and sodium hydroxide, if the sound is abnormal, the internal chemical substances are proved to be invalid, and the wristwatch is checked before use by the checking control of the two points, so that the reliability of the wristwatch is ensured.
The above-mentioned heat-sensitive metal sheet 4 is designed to be heat-sensitive material as the upper material, and the lower material may be designed to be heat-sensitive material to be crimped over the upper check valve, and the crimped outward expansion after being heated closes the upper check valve 3.
In the invention, 4 groups of comparison tests are mainly set on the reaction water inflow, 5 groups of comparison tests are set on the reaction medicament formula, and main observation parameters comprise the highest water temperature T1 of the reaction environment, the highest temperature T2 of the reaction and the complete filling time S of the air bag.
The principle of the invention: 2al+2naoh+2h2o=2naalo2+3h2 ∈
The medicament proportion is as follows: the generation of 7L of hydrogen under standard conditions requires 8.3g of sodium hydroxide and 5.6g of aluminum, the analytically pure grade reagent adopted in the experiment is granular, the aluminum is divided into aluminum powder and 0.8mm aluminum wire, and the excess of the reaction raw materials is 10 percent, namely 9.1g of sodium hydroxide and 6.2g of aluminum, in order to ensure the sufficient gas yield.
1. The reaction water inflow and experimental results are as follows
| Reaction water inflow (ml) | Ambient maximum water temperature T1 (. Degree.C) | Maximum temperature T2 (. Degree. C.) of reaction | Time S (seconds) for complete filling of air bag |
| 50 | 40 | 130 | >60 |
| 100 | 39 | 127 | 5 |
| 200 | 35 | 119 | 5.5 |
| 300 | 28 | 101 | 11 |
(the experimental proportion is tested by adopting the proportion with the medicament number of 2), and the experimental result analysis is that: the experimental result shows that the gas production is insufficient due to the too small water inflow, the water which is needed to be reacted is gasified into the air bag by the preliminary analysis of the reaction heat release, so that the water needed by the reaction is insufficient, in addition, when the water inflow is too large, the liquid water is gasified to be small due to the low reaction temperature, so that the gas charging speed is slowed down, and the water inflow is about 100 ml. That is, the inflow should be reduced while ensuring that the reaction gas production is sufficient, and the inflow in the wrist watch is controlled by the built-in spring, and the air bag swelled after the wrist watch is started forms negative pressure to guide the water to flow into the wrist watch.
2. The proportion of the reaction agent and the experimental result are as follows
| Medicament proportion number | Sodium hydroxide weight (g) | Aluminum powder weight (g) | Weight of aluminum wire (g) | Ambient maximum water temperature T1 (. Degree.C) | Maximum temperature T2 (. Degree. C.) of reaction | Time S (seconds) for complete filling of air bag |
| 1 | 9.1 | 6.2 | 0 | 40 | 129 | 4.5 |
| 2 | 9.1 | 4.65 | 1.55 | 38 | 115 | 5 |
| 3 | 9.1 | 3.1 | 3.1 | 31 | 107 | 15 |
| 4 | 9.1 | 1.55 | 4.65 | 28 | 95 | >60 |
| 5 | 9.1 | 0 | 6.2 | 26 | 79 | >60 |
(the water yield of the experiment is 100 ml) analysis of experimental results: the experimental result shows that the reaction is more intense along with the increase of the aluminum powder proportion, the reaction instant heat release amount is increased, the reaction temperature is increased, the gas production speed is increased, and the first group and the second group of comparison experiments show that although the aluminum powder proportion is reduced, the gas production speed is not greatly influenced. Further, it was observed in the experiments that the more the aluminum powder mixture ratio was, the more the reaction solution boiled, the more the reaction substance was sprayed, wherein the first group of experiments were sprayed more strongly, the pressure in the air bag was initially maintained at a pressure of 10KP or more, but the air bag pressure in the first group of experiments had a tendency to decrease over time, in addition, there was liquid water condensation in the air bag over time, and the less water eventually condensed down with the decrease in aluminum powder mixture ratio, which suggests that part of the water was gasified and charged into the air bag due to the high temperature of the reaction, and the water vapor in the air bag was cooled into liquid water by the ambient water, resulting in a decrease in the air bag pressure. It is worth mentioning that after 5 hours, the air bag pressure is observed again, the air bag pressure of the experimental group with less aluminum powder proportion is higher instead, and the preliminary analysis is that the instant high temperature of the aluminum powder and sodium hydroxide reaction not only gasifies part of liquid water, but also takes away part of liquid water and part of aluminum powder, so that the reaction raw material is reduced, and the gas production is reduced.
Summary of the experiment: in the early stage of the inflatable air bag, a large amount of water vapor is actually introduced, so that adverse factors are not generated for life saving, the key is that after the pressure is reduced under the condensation of the water vapor, the pressure of hydrogen is required to be supplemented, so that the reaction is not too severe, a certain aluminum wire is required to be added after the condensation of the later water vapor, the air bag cannot react at the first time, and the pressure can be supplemented when the subsequent pressure is reduced, so that the gas production rate is ensured, the proportion of aluminum powder is ensured, and in the above groups of comparison tests, the proportion of the second group of agents is optimal in five groups.
