Description

lighter with igniter mechanism

The utility model relates to a lighter, in particular to a lighter with an igniter mechanism.

The flame of an ordinary lighter is located at the outlet of the ignition tube at the upper end of the lighter body, and the user can easily use the lighter to light cigarettes by holding the lighter. When used for other ignition purposes, such as lighting gas stoves, craft candles, kerosene lamps, etc. It is inconvenient to use near the ignited object.

There has been a lighter with an igniter mechanism, which is provided with a retractable ignition tube, which can lead the flame away from the lighter body, so that the flame can easily approach the ignited object, which is very convenient to use. No. JP-A-10-169980 Japanese Laid-Open Patent discloses a lighter with an igniter mechanism, as shown in Figure 1, this lighter is provided with a length that allows the elongated ignition tube 5 to stretch out from the lighter shell The backguy type telescopic mechanism of this telescoping mechanism is made of upper cable pulley 62, lower cable pulley 61, guide wheel 63, stay cord 64 and ignition tube slide seat 9. The upper wire pulley 62 and the pull wire pulley 61 are respectively rotatably fixed on the inner wall of the lighter casing and the pressing plate slide seat 33, and the guide wheel 63 is also rotatably fixed on the inner wall of the lighter casing. One end 64a of the stay cord 64 is fixed on the inner wall of the housing 1, and the stay cord 64 is wound around the pull wire pulley 61 and then the upper pull pull wire pulley 62, then returns to the pull pull wire pulley 61, and after passing around the pull pull wire pulley 61 for the second time Then go around the upper cable pulley 62, extend to the guide pulley 63 and walk around the guide pulley 63, and fix the other end 64b of the stay rope 64 on the ignition tube slide seat 9. The user holds the lighter and uses the thumb to turn the friction wheel 22 of the ignition device F, and presses the pressing plate 29 to make the gas outlet of the ignition tube 5 ignite the flame, then continues to press the pressing plate 29, and the pressing plate slide seat 33 follows the pressing plate. 29 moves down together, thus drives pull-down wire wheel 61 to move downward, and the distance between two pull-wire pulleys increases with the downward movement of pressing plate slide seat 33, and the ignition tube slide seat 9 that is connected to the other end 64b of stay cord 64 follows It is lifted up, and the ignition tube 5 that forms one with it is just promoted same height, stretches out shell. Because the stay cord walks around the guy wheel twice, the length that the ignition tube stretches out of the shell is about 4 times of the downward stroke of the pressing plate slide. Because the ignition tube leads the flame away from the lighter body, it can easily ignite the to-be-ignited object that is inaccessible to the hand-held lighter.

This kind of lighter with an ignition mechanism can be easily applied to various occasions, but due to the use of a double-wound runner pulley type telescopic mechanism, the structure is relatively complicated and difficult to install, so it is not conducive to large-scale industrial production. Large, the pull rope wears a lot, is easy to break, and has a short service life.

In view of the above-mentioned shortcomings in the prior art, the purpose of this utility model is to provide a lighter with an igniter mechanism that is simple in structure, easy to assemble and has a long service life.

In order to achieve the above purpose, the lighter with an igniter mechanism provided by the utility model includes: a casing, a liquefied gas storage chamber, an inflatable mechanism, a gas injection mechanism, an ignition tube telescopic mechanism, a pressing plate operating mechanism, an ignition mechanism and an ignition tube assembly , It is characterized in that the ignition tube telescopic mechanism is composed of a rack and pinion, a pulley and a guide belt two-stage transmission mechanism.

Because the two-stage transmission mechanism composed of rack and pinion and pulley guide belt is used to replace the cable-type transmission mechanism of the prior art, the wear of the belt rope is reduced, and the service life is prolonged, and the structure is relatively simplified, making it simple to assemble and easy to install. Form industrial scale production.

The action of the lighter will be described below.

The user holds the lighter in his hand and usually moves the friction ratchet 601 with his thumb. The friction ratchet 601 rubs against the flint 602 pressed against the lower periphery of the friction ratchet by the pressing spring, and sparks are emitted and shoot to the gas outlet of the ignition tube 701; Press the pressing plate 501, and the pressing plate 501 drives the connecting rod 504, prompting the lever opening and closing mechanism 304 to act, thereby opening the valve plate 301, allowing the liquefied gas in the liquefied gas storage chamber 102 to flow out. , The nozzle 303 sprays into the conduit 703, reaches the upper port of the ignition tube 701, and is ignited when encountering the spark emitted by the ignition mechanism 600, and ejects flames.

The rack 505 meshes with the gear 401 of the ignition tube telescopic mechanism 400, so the gear 401 rotates clockwise (Fig. 2) driven by the rack 505, and the pulley 402 also rotates at the same time, and the guide belt 404 is wound on the belt. On the wheel 402, the other end of the guide belt 404 connected to the ignition tube slide 702 moves upwards with the winding of the guide belt. 703 moves up, makes ignition tube 701 stretch out a certain height of lighter with the flame being ignited. Because the flame at the top of the ignition tube 701 is drawn away from the lighter body, it is easy to ignite the inflamed objects that are inaccessible to the hand-held lighter.

If the distance that the pressing plate 501 continues to be pushed down is H1, the diameter of the pulley 402 is D1, and the pitch circle diameter of the gear 401 is D2, then the stroke length H2=H1×D1/D2 of the upward movement of the ignition tube 701.

When the thumb released the pressing plate 501, the ignition tube 701, the pressing plate 501 and the pressing plate slide seat 502 returned to their original positions under the action of the coil spring 704 and the pressing plate spring 503 simultaneously, and the flame went out simultaneously.

Above, the utility model has been described illustratively in the form of embodiments, but the utility model is not limited to the above embodiments, for example, it is not only applicable to lighters that use flint to ignite, but also applicable to piezoelectric igniter lighters and the like.
