Abstract

The utility model provides an electrical kindling battery type firework and firecracker micro ignitor, which comprises a cavity, a top cover, a bottom cover, a fuse head with an electrically heated wire, a pushbutton arranged on the top cover, a safety relief spring arranged below the pushbutton in the cavity, a switch, a positive conductor, a battery, a negative spring, a positive conducting wire and a negative conducting wire. The upper part of the switch is connected with the pushbutton through the safety relief spring, the positive conductor is arranged at the bottom of the switch, protuberances are arranged on both sides of the upper part in the cavity, the lower part of the switch is arranged between the protuberances, the battery is arranged below the lower part of the switch, the positive conductor is connected with the positive electrode of the battery, the negative spring is arranged on the bottom cover and is connected with the negative electrode of the battery, the positive conductor and the negative spring are respectively connected with the positive conducting wire and the negative conducting wire, the positive conducting wire and the negative conducting wire are connected with the fuse head. The utility model adopts the battery to produce instant current to ignite the electric fuse head, thereby being capable of safely and reliably igniting the bodies of fireworks and firecrackers; the utility model has the advantages of safety and reliability and so on.

Description

The miniature igniter of electrically-ignited battery type fireworks and firecrackers

(1) technical field

The utility model relates to a kind of miniature igniter, is specifically related to a kind of fireworks and firecrackers miniature igniter of electrically-ignited.

(2) background technology

Fireworks and firecrackers is widely used in China's traditional festival or the celebrating celebration always, and traditional ignition way of fireworks and firecrackers is to light with naked light, detonation velocity inconvenience control, human body safe distance between explosive is short, very easily damage, because fireworks and firecrackers leaves fuse outward, and is explosive inflammable in the transportation, the security extreme difference.Therefore, the improvement for fireworks and firecrackers and firing device thereof is the emphasis that people pay close attention to always.

(3) summary of the invention

The purpose of this utility model is to provide a kind of employing battery to produce the immediate current electric igniter that ignites, thereby the safety electric of reliable ignition fireworks and firecrackers main body is lighted the miniature igniter of battery type fireworks and firecrackers.

The purpose of this utility model is achieved in that it comprises cavity, top cover, bottom, igniter head of charged heated filament, be arranged on the button on the top cover, be arranged on the security insurance spring of button below in the cavity, switch, cathode conductor, battery, negative spring and just, cathode conductor, switch top connects button by the security insurance spring, cathode conductor is installed in the bottom of switch, the both sides of cavity internal upper part are provided with projection, the switch bottom is installed in the middle of the projection, battery is installed in the below, anodal conductor and anode join, negative spring is installed on the bottom and connects GND, cathode conductor just is being connected respectively with negative spring, cathode conductor, just, cathode conductor tie point duration and degree of heating.

The utility model also has some technical characterictics like this:

1, described button is provided with the button shell above top cover.

The utility model can produce the 1.3V burning voltage, make battery produce transient voltage by pushing button, and igniter head internal electrical heated filament that passes through the connection of both positive and negative polarity lead produces localized hyperthermia's point of ignition duration and degree of heating, thereby light the fireworks and firecrackers main body, the security insurance spring is the lockable button when not using, and prevents maloperation.The utility model can be provided with the both positive and negative polarity conductor length as required in addition, thereby makes the people away from the fireworks and firecrackers main body, has substituted traditional ignition way, has more security and reliability.

(4) description of drawings

Accompanying drawing is the utility model schematic diagram.

(5) specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is described further:

In conjunction with the accompanying drawings, present embodiment comprises plastic chamber 5, top cover 2, bottom 8, igniter head 12 of charged heated filament, be arranged on the button 1 on the top cover 2, be arranged on the security insurance spring 3 of button 1 below in the cavity 5, switch 4, cathode conductor 6, battery 7, negative spring 9, with both positive and negative polarity lead 10,11, switch 4 tops connect button 1 by security insurance spring 3, cathode conductor 6 is installed in the bottom of switch 4, the both sides on cavity top are provided with projection, switch 4 bottoms are installed in the middle of the projection, battery 7 is installed in the below, anodal conductor 6 joins with battery 7 positive poles, negative spring 9 is installed on the bottom 8 and connects battery 7 negative poles, cathode conductor 6 is connected both positive and negative polarity lead 10 respectively with negative spring 9,11, both positive and negative polarity lead 10,11 tie point duration and degree of heatings 12.Present embodiment carries out security protection by security insurance spring 3 locking switches and button, button is provided with the button shell above top cover, earlier the button shell is screwed off during use, security insurance spring 3 ejects automatically, screw on the button shell then or directly push button, in battery 7, produce transient voltage by switch 4,, thereby ignite fireworks and firecrackers main body 13 by lead 10,11 output current firing point duration and degree of heatings 12.

Fireworks and firecrackers described in the utility model equally also can be regarded as the pyrotechnics similar with it, priming system and all belongs to this case protection domain.
