Abstract

The utility model discloses a fireworks and crackers trigger which comprises a direct current supply, as well as elements connected in series through the direct current supply, i.e. a direct current electronic high-pressure generator, a switch, and an electrode which is used for generating trigging spark; the switch and the electrode are connected together through a prolonged wire and the prolonged wire can leave an operator in safe distance when an operator presses the switch. The utility model enables the operator to set off firecrackers safely by separating the electrode from the switch and making the direct current supply discharge to inflame a lead wire. Moreover, the utility model has a simple structure and a low production cost.

Description

A kind of fireworks trigger

Technical field

The utility model relates to a kind of fireworks apparatus to cause bursting.

Background technology

Fireworks are the traditional celebrating articles for use of China, are used in the festival celebration such as the Spring Festival, wedding feast; in opening or the like the celebration, especially during the Spring Festival, in not by the city of firework control and rural area; almost every household all will be bought the fireworks of some and firecracker etc., the article of setting off during as festival celebration.

But lighting of present most of fireworks needs naked light, and the burning velocity of its lead-in wire is all very short, closely lighting the back, as easy as rolling off a log fireworks promptly fire at manipulator's safe distance that do not have enough time as yet to arrive, and cause the security incident in festivals or holidays to emerge in an endless stream.

Therefore, prior art has yet to be improved and developed.

The utility model content

The purpose of this utility model is to provide a kind of fireworks trigger, by high voltage direct current generator, can be by the lifting of DC voltage, and electrode point of discharge burning smoke firework bamboo outside safe distance, and guarantee manipulator's safety.

The technical solution of the utility model is as follows:

A kind of fireworks trigger is characterized in that, comprises a direct current power supply, and a direct current electronics high pressure generator that connects successively by this dc source, a switch, and one be used to produce the electrode of igniting spark; Be connected by extension lead between described switch and the described electrode, described extension lead is in the safe distance when being enough to make manipulator's push switch.

Described fireworks trigger wherein, also is provided with one and blocks over cap before the described electrode, the described over cap that blocks is provided with a hole portion that allows lead-in wire to pass.

Described fireworks trigger, wherein, the described over cap that blocks is discoid, described hole portion is arranged on the center, and with described electrode separation setting.

Described fireworks trigger, wherein, described dc source, described DC electronic high pressure generator and switch are arranged in the box body.

Described fireworks trigger wherein, also is provided with an indicator lamp on described box body, and is connected in parallel in the circuit, is used to whether indicate circuit turn-on.

Described fireworks trigger wherein, is characterized in that, described electrode is arranged on the finger of hand-type clip.

Described fireworks trigger wherein, is characterized in that, described dc source is a battery.

A kind of fireworks trigger provided by the utility model owing to adopt separating of electrode and switch, and the DC voltage discharge lead-in wire that ignites, realized the set off fireworks function of firecracker of manipulator's safety, and it is simple in structure, and production cost is low.

Fig. 2 is a hardware configuration schematic diagram of the present utility model.

The specific embodiment

Below preferred embodiment of the present utility model is described in detail.

Fireworks trigger 100 of the present utility model, in the circuit as shown in Figure 1, it has comprised a direct current power supply 110, can adopt disposable dry cell one joint or two joints, perhaps rechargeable battery, an and direct current electronics high pressure generator 120 that connects successively by this dc source 110, one switch 130, and one be used to produce the electrode 140 of igniting spark, this electrode can be arranged on the both sides of a clip, slightly leave certain space in clamping place, on the lead-in wire 200 that conveniently is clamped in fireworks; Be provided with extension lead 150 between described switch 130 and the described electrode 140 and be electrically connected, the length of described extension lead 150 needs long enough, for example can be provided with more than 5 to 10 meters, is enough to make the manipulator to be in the safe distance when push switch and gets final product.

The utility model fireworks trigger can also be provided with one and block over cap 160 before described electrode 140, the described over cap 160 that blocks is provided with a hole portion 161 that allows lead-in wire to pass; Specifically can be set to the described over cap 160 that blocks discoid; described hole portion 161 is arranged on the center; and can with described electrode separation setting, so can make things convenient for earlier lead-in wire is stretched into described block over cap after, then electrode 140 is clamped to described blocking on the lead-in wire that exposes behind the over cap.

For convenient for assembly; the utility model fireworks trigger is arranged on described dc source 110, described DC electronic high pressure generator 120 and switch 130 in the box body 170; as shown in Figure 2; this box body protection has loam cake and lower cover; and form one in inside and install the space, above-mentioned parts can be installed wherein.Described switch 130 can be arranged on box body directly over, expose the press section.And, also an indicator lamp 180 can be set in circuit, be arranged on the described box body 170, can be provided with near described switch 130, and be connected in parallel in the circuit, when when depressing switch 130 and make circuit turn-on, this indicator lamp can be used to whether indicate circuit turn-on.

Described electrode 140 of the present utility model is arranged on the finger of hand-type clip, and so the effect that can make the manipulator understand this electrode intuitively is used for the clamping lead-in wire.

The operation principle of the utility model fireworks trigger is as follows: at first, the lead-in wire of fireworks to be lighted is passed the centre bore portion 161 of blocking over cap 160, be exposed to outside the centre bore portion, described electrode 140 is clamped on this lead-in wire.Hold switch and box body 170 then in safe distance, can be by the push switch lead-in wire that ignites.Behind push switch 130, as shown in Figure 1, the entire circuit conducting because DC electronic high pressure generator 120 produces high pressure, produces the spark of enough energy, thereby ignites lead-in wire between electrode.

Like this, fireworks trigger of the present utility model just can make the manipulator on the scope safer apart from fireworks to be lighted, the some combustion wire.Its circuit theory is simple, and used unit all can obtain from the market at a low price, so cost is very low, is easy to promote.The utility model product concerning playing the fireworks and firecrackers person, especially not strong child to judgment, the enjoyment that their happy enjoyment fireworks and firecrackers is seted off can guarantee manipulator's safety again, is a kind of simple and effective safe ignition device.

Should be understood that, for those of ordinary skills, can be improved according to the above description or conversion, and all these improvement and conversion all should belong to the protection domain of the utility model claims.
