Description

Electric igniter structure

The present invention relates to an igniter, and more particularly to an electric igniter structure having a small volume, high stability, and high excitation success rate.

According to the heat battery, the main function of the ignition head is to ignite the material called heat paper in the heat battery. The hot paper is mostly made of zirconium powder and barium strontium sulphate (BaCrO ₄ ) and glass fiber, ceramic fiber, etc. The mixture is then made into a paper shape through a papermaking process, and then used as a reel or a cut strip in accordance with the ignition method. The igniting of the hot paper is mainly the use of an igniter. The igniter generally provides lower heat, and the emphasis is on the fact that the heat can be reliably supplied to the hot paper. The igniter is mainly excited by electric energy and mechanical energy. The development of laser ignition has also begun. Basically, it provides sufficient heat energy to the gun in the ignition head to promote the complete reaction of the gunpowder. Therefore, the development of an effective and reliable ignition head excitation method is also the main direction of research. Among them, the semiconductor bridge uses directional physical vapor deposition to manufacture the wire. The semiconductor bridge igniter can overcome the shortcomings of the ordinary bridge wire heating unevenness, but can not solve the reliability problem of the highly sensitive gunpowder, mainly because of high sensitivity. The excitation energy of the gunpowder is low. If the semiconductor bridge is not designed with electromagnetic shielding, the energy generated by the electromagnetic wave can make the heat of the bridge reach the level of the reaction of the gunpowder. The use of laser ignition can greatly increase the ambient temperature that the thermal battery can withstand. Improvement, its main disadvantage is the loss of radiant energy and the need to adjust according to the density of the mixture Irradiation diameter, many need to install additional equipment, space and increase the cost of the financing.

In order to enable your review committee to have a better understanding and understanding of the purpose, features and effects of the present invention, please refer to the following [Simplified Description of the Drawings] for details: First, please see Figure 1 for an electric The igniter structure includes a base 10, a nano-multilayer sheet 20 and a two-silver glue film 30. The base 10 is provided with an insulator 11 and two metal guide sheets 12, and the insulator 11 of the base 10 is The glass guide material 12 is made of copper material, and the nanometer multilayer sheet 20 is formed by alternately stacking two metal thin films (21a) (21b), and the nano multilayer sheet 20 is disposed on The nanometer multilayer sheet 20 has a total thickness of between 40 μm and 300 μm on the susceptor 10, and the atoms of the two metal thin films (21a) (21b) are mixed to form a compound by energetic excitation, and further at 1 m/s. An exothermic reaction between 1000 and 3000 degrees Celsius is generated between 30 m/s, and the two metal films (21a) (21b) of the nano multilayer sheet 20 are nickel (Ni) and aluminum (Al), respectively, and the metal film (21a) (21b) has a thickness of between 10 nm and 100 nm, and the nano multilayer sheet 20 has a length of 10 mm and a width of 3 mm, and the silver The film 30 has a length of 1 mm to 4 mm and a width of 3 mm. The two silver film 30 is applied to the metal guide 12 of the base 10, and the nano film 20 is bonded by the silver film 30. The thickness of the adhesive film 30 is controlled between 10 μm and 20 μm, which avoids direct contact between the nano multilayer sheet 20 and the metal guide sheet 12, and forms a stable assembly of the nano multilayer sheet 20 and the base 10, and the silver paste The film 30 is made of a resin mixed silver powder to form a viscosity and conductivity, and a gunpowder is added to the silver film 30, and the powder component is a mixture of zirconium powder and potassium perchlorate (Zr/KClO ₄ ), and the proportion of the powder is added. Between 0.1 and 1% by weight (the more the resistance is added), the resistance of the silver film 30 can be increased by using the gunpowder to a range of 1 Ω to 10 Ω, so that the metal guide 12 can be turned on at a voltage of 4 V or higher. A short-circuit excitation is generated at the silver film 30, thereby exciting the nano-multilayer sheet 20 for ignition purposes.

This creation proves its function by experimental results. Please firstly show the short-circuit excitation test of the nano-multilayer sheet 20, and observe the excitation state to find the best excitation condition. The short-circuit excitation test is to The nano-multilayer sheet 20 is fixed by an alligator clip on the positive electrode. After the voltage is set, the negative electrode wire is brought close to the nano-multilayer sheet 20. It is found by experiments that at least a voltage of 4 V is required to smoothly excite the nano-multilayer sheet 20, which proves that the voltage is higher than 4V can short-circuit the nano-multilayer sheet 20. In this experiment, the short-circuit voltages are further tested at 8V, 12V and 16V, and the composition analysis and SEM surface observation by EDS mapping show that the voltage rise will make the The exothermic reaction of the nano-multilayer sheet 20 is more intense. Since the arc-fired by close contact also requires the displacement mechanism to control the approach, the installation cost and the overall volume are additionally increased, and the probability of firing is also reduced. The means is that the nano-multilayer sheet 20 can be excited without moving, that is, the nano-layer sheet 20 is regarded as a ring of the whole electrical circuit during the production, and two of the nano-multilayer sheets 20 are Deliberately creating a short circuit condition, a silver paste film 30 having a thickness of about 10 μm to 20 μm is applied between the nano multilayer sheet 20 and the joined metal guide sheet 12, and the silver paste film can be applied when a voltage greater than 4 V is passed. A short circuit phenomenon occurs at 30 places, thereby generating thermal energy, and the heat energy generated by the short circuit is covered by the nano multilayer sheet 20 and the susceptor 10, so that the heat can be rapidly increased by more than 200 ° C / min, thereby short-circuiting The spark generated is sufficient to excite the nano-multilayer sheet 20, and a development test is conducted for the excitation method: the nano-layer sheet 20 has a thickness of 60 μm, a length and a width of 10 mm*3 mm, and is multilayered in the nano layer.

Test 2: The nano-multilayer sheet 20 was bonded to the metal guide sheets 12 at both ends of the susceptor 10 by using a silver glue film 30 to which no gunpowder was added. After applying a fixed voltage of 18 V, it was found that a short circuit effect could not be produced, and the nano-multilayer sheet 20 was unsuccessful. Excited, this type of test piece was later successfully excited by the arc, so it was confirmed that the failure of the nano-multilayer sheet 20 was not obtained, and the test result proved that the reason why the excitation could not be excited was that the resistance value of the silver film 30 was too low (about 0.002 Ω). ), causing the current to become a loop directly through unobstructed.

The higher the resistance value of the electrical circuit, the better the statistical value is between 0.1 Ω and 10 Ω, and the addition ratio of the gunpowder will be between 0.1 and 1 wt%, and the short circuit can ignite. The gunpowder can further increase the heat generated during the short circuit, so that the probability of exciting the nano multilayer sheet 20 is improved. In the test, it is known that the unilateral addition of the gunpowder and the bilateral addition of the gunpowder can produce the same short-circuit excitation effect, and it can be proved that the silver-glue film 30 can be selected to add the gunpowder only at the end of the metal guide 12, or the silver paste. The film 30 is provided with a gunpowder at both ends of the metal guide 12 at both ends, that is, the resistance between the two metal guides 12 is controlled to be in the range of 1 Ω to 10 Ω to achieve short-circuit excitation.

Test 4: The nano multilayer sheet 20 is bonded to the metal guide sheets 12 at both ends of the base 10 by using a silver paste film 30 to which a gunpowder (Zr/KClO ₄ ) is added, and the surface of the nano multilayer sheet 20 is provided with a gunpowder coating. 22 (Zr/KClO ₄ ), as shown in FIG. 2, it is found through the test results that the nano-multilayer sheet 20 ignites the powder coating 22 when excited, thereby improving the nano-layer sheet 20 in heat release.
