Abstract

The utility model relates to a piezoelectric ignition lighter, which comprises a shell, a piezoelectric device in the shell, a gas chamber and gas valve components thereof. The upper end of the shell is provided with an activation button which presses against the piezoelectric device and an electric slice which is arranged between the piezoelectric device and the activation button; the gas valve components comprises a gas outlet pin and a metal seesaw with one end connecting with the pin. The utility model is characterized in that the piezoelectric device is reversely arranged inside the shell; a copper anvil which serves as one of electrodes is arranged at the top of the device while a piezoelectric cap is arranged at the bottom thereof; an exposed metal slice which serves as another electrode is positioned at the side wall of the piezoelectric device; the seesaw approximately shows a reverse 'L' shape and the side thereof is connected with the metal slice while the top side is connected with the gas outlet pin; the electric slice is provided with an extended part which stretches to the gas outlet pin side. Compared with the prior art, the utility model has the advantages that the piezoelectric device is reversely arranged inside the shell so as to ensure that the side of the seesaw can be directly contacted with the electrode; a wire is unnecessary to be led out from the side wall of the piezoelectric device with simple structure, thereby assembly is convenient, work efficiency is improved and labor is further saved during piezoelectric ignition.

Description

A kind of piezo-electric ignition formula lighter

Technical field

The utility model relates to a kind of lighter, particularly a kind of piezo-electric ignition formula lighter.

Background technology

At present, match withdraws from average family substantially, the substitute is lighter and burning torch, lighter wherein commonly used generally comprises shell, be positioned at the piezo-electric device of shell, fuel chamber and air-valve assembly thereof, shell upper end be provided with and piezo-electric device in the piezoelectricity cap offset press hand and place conducting strip between the two, wherein air-valve assembly comprises the metal seesaw that an air-out needle and an end link to each other with air-out needle again, piezo-electric device has two output electrodes, wherein one very be arranged on the copper anvil that one is brought in, in piezo-electric device inside, this copper anvil serves as that conduction is connected with piezoelectricity cap with the conductive plastics material, the lead that another very stretches out from its sidewall middle part, this lead must extend to air-out needle adjacent position and location, during use, press hand with subordinate's pressure, make the compression of piezoelectricity cap, drive the seesaw perk at the conducting strip of pressing between hand and the piezoelectricity cap simultaneously, air-out needle is pulled outwardly and makes the air valve venting, this moment, air-out needle was through the metal seesaw, conducting strip, the piezoelectricity cap has formed conduction with the copper anvil and has been connected, therefore when the piezoelectricity cap is compressed into the piezoelectricity stroke, will be between the lead of piezo-electric device side-walls and the air-out needle because of electrion produce spark, ignite and overflow combustion gas and light a fire from air valve.As seen, what piezo-electric device adopted in this lighter is the forward mounting means that the copper anvil places the bottom, therefore must draw the lead of another utmost point from its side-walls, and must be with the proper location of lead, its structure relative complex, and processing, installation be inconvenience to some extent all.

Summary of the invention

Technical problem to be solved in the utility model is at above-mentioned prior art present situation, and a kind of lighter easy, simple in structure that assembles is provided, and it need not to draw lead from sidewall.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: this piezo-electric ignition formula lighter includes shell, be positioned at the piezo-electric device of shell, fuel chamber and air-valve assembly thereof, be provided with in described shell upper end and piezo-electric device offsets presses hand and place conducting strip between the two, described air-valve assembly comprises the metal seesaw that an air-out needle and an end link to each other with this air-out needle, it is characterized in that described piezo-electric device inversion in the enclosure, also promptly place the top as the copper anvil of one of them electrode, the piezoelectricity cap then places the bottom, the sidewall of piezo-electric device is provided with the sheet metal that exposes as its another electrode, described seesaw roughly is " factory " font, its side promptly contacts with this sheet metal, its top margin promptly links to each other with air-out needle, and described conducting strip then has the extension that stretches to the air-out needle side.

Be the enhanced discharge effect, the extension front end of described conducting strip is good to be needle-like.

Compared with prior art, advantage of the present utility model is because piezo-electric device is inverted in the shell, make the side of seesaw directly to touch mutually with electrode, therefore need not to draw lead from the sidewall of piezo-electric device, more need not to set up an organization is located, thereby makes the overall structure of lighter become more simple, also therefore made things convenient for assembling, enhance productivity, on the other hand, the seesaw of " factory " font also makes when piezo-electric ignition more laborsaving.

Description of drawings

Fig. 2 shows schematic diagram for the partial cutaway that lighter among Fig. 1 is under the sparking state.

The specific embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

Extremely shown in Figure 2 as Fig. 1, present embodiment comprises shell 5, is positioned at the piezo-electric device 3 of shell 5, fuel chamber 4 and air-valve assembly thereof, be provided with in shell 5 upper ends and press hand 1, wherein air-valve assembly comprises the seesaw 6 of air outlet valve (not looking among the figure), air-out needle 8 and metal material, piezo-electric device 3 comprises copper anvil 31, piezoelectrics 33 and piezoelectricity cap 34, and piezo-electric device 3 is inverted in the shell 5 after assembling in the usual way, and promptly copper anvil 31 places the top, and be positioned at and press under the hand 1, be provided with conducting strip 2 between the two; In the present embodiment, above-mentioned seesaw 6 is " factory " font, and its top margin 61 links to each other with air-out needle 8, and its side 62 touches mutually with the exposed metal sheet 32 that is positioned at piezoelectrics 33 sidewalls; Described conducting strip 2 has the extension 21 that stretches to air-out needle 8 sides, and the front end of this extension 21 is needle-like, and when pressing when pressing hand 1, the front end of this extension 21 moves to the position of contiguous air-out needle 8; In the present embodiment, above air-out needle 8, also be provided with the flame adjusting ring 7 that is used for windproof fan housing 9 and regulates flame size.

When lighter uses, depress and press hand 1, make the conducting strip 2 that is positioned under it, the copper anvil 31 and the piezoelectrics 33 of piezo-electric device 3 move down, the protuberance 331 of piezoelectrics 33 sides is oppressed the side 62 of seesaws 6 simultaneously, make top margin 61 perks of seesaw 2 and jack-up air-out needle 8 and make the air outlet valve venting, when piezoelectrics 33 reach the piezo-electric ignition stroke, the transient voltage that in piezoelectrics 33, produces, one utmost point is delivered to air-out needle 8 by the sheet metal 32 of piezoelectrics 33 sidewalls through seesaw 6, another utmost point passes through copper anvil 31 to conducting strip 2, owing to the contiguous air-out needle 8 of extension 21 of conducting strip 2 this moment, therefore generation is immediately discharged and is lighted the combustion gas of releasing from air outlet valve between the two, realizes igniting.
