Abstract
The utility model provides an electrical kindling piezoelectric ceramic 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 piezoelectric ceramic, a positive conducting wire and a negative conducting wire, wherein, the upper part of the piezoelectric ceramic is connected with the pushbutton through the safety relief spring, the piezoelectric ceramic is 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 takes advantage of the piezoelectric ceramic to produce the instant high pressure by pressure to ignite fireworks and firecrackers, changes the prior open-fire kindling of fireworks and firecrackers to the electrical kindling, and has the advantages of safety and reliability and so on.
Description
(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, and human body safe distance between explosive is short, very easily damages, and is explosive inflammable in the transportation because fireworks and firecrackers leaves fuse outward, 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 piezoelectric ceramics to produce the immediate current electric igniter that ignites by pressure, thereby the safety electric of reliable ignition fireworks and firecrackers main body is lighted the miniature igniter of piezoelectric ceramic type fireworks and firecrackers.
The purpose of this utility model be achieved in that it comprise cavity, top cover, bottom, charged heated filament igniter head, be arranged on the security insurance spring, piezoelectric ceramics and the positive and negative electrode lead that are arranged on the button below in button on the top cover, the cavity, piezoelectric ceramics top connects button by the security insurance spring, piezoelectric ceramics connects the positive and negative electrode lead respectively, positive and negative electrode lead tie point duration and degree of heating.
The utility model also has some technical characterictics like this:
1, the left and right sides, top is provided with projection in the described cavity, and piezoelectric ceramics is arranged in the middle of the projection;
2, described bottom is provided with spring;
3, described button is provided with the button shell above top cover.
The utility model adopts the piezoelectric ceramics of 1.45kv voltage, 200PF electric capacity, make piezoelectric ceramics produce transient voltage by pushing button, and, light the fireworks and firecrackers main body thereby make igniter head internal electrical heated filament produce localized hyperthermia's point of ignition duration and degree of heating by igniter head that the both positive and negative polarity lead connects.Bottom of the present utility model can conveniently be installed the replacing inner body, and the security insurance spring is the lockable button when not using, and prevents maloperation.In addition, the utility model can be provided with the positive and negative electrode conductor length as required, thereby makes the people away from the firecracker main body, has substituted traditional ignition way, has more security and reliability.
(4) description of drawings
Accompanying drawing is the utility model structural representation.
(5) specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further described:
In conjunction with the accompanying drawings, present embodiment comprise cavity 5, charged heated filament igniter head 9, be arranged on the security insurance spring 3 that is arranged on button 1 below, piezoelectric ceramics 4 and positive and negative electrode lead 6,7 in button 1 on the cavity top cover 2, the cavity, the left and right sides, top is provided with projection in the cavity 5, piezoelectric ceramics 4 is arranged in the middle of the projection, its top connects button 1 by security insurance spring 3, button 1 is provided with the button shell above top cover 2, piezoelectric ceramics 4 connects positive and negative electrode lead 6,7 respectively, positive and negative electrode lead 6,7 tie point duration and degree of heatings 9.Present embodiment security insurance spring 3 lockable button 1 when not using prevents maloperation.Earlier igniter head is put into fireworks and firecrackers main body 9 during use, 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, when pushing button, in piezoelectric ceramics 4, produce instantaneous pressure,, thereby ignite fireworks and firecrackers main body 10 by lead 6 and 7 output voltage firing point duration and degree of heatings 9.The bottom 8 of cavity bottom is provided with spring, can use when being equipped with battery.
The said fireworks and firecrackers of the utility model equally also can be regarded as the pyrotechnics similar with it, priming system and all belongs to this case protection domain.
