Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to an easy-to-use and safe household ignition device.

[0002]

[Prior art]

 When enjoying a barbecue, fireworks or bonfire outdoors, a commercially available match is generally used, and sometimes a commercially available disposable lighter is used. Pistol-type igniters are sold, but are relatively expensive and rarely used in general. As for products with automatic ignition, the igniter is dedicated to equipment and has no versatility, and cannot be used for barbecue or bonfire ignition.

[0003]

[Problems to be solved by the invention]

 For barbecues and bonfires, the match is very difficult to ignite because the burning time is very short. It is not easy to ignite with a commercially available disposable lighter, and it is dangerous to incline the lighter during ignition work because the flame will come close to your hand and your hand will easily burn your hand.

[0004] With respect to the pistol type ignition device, the type accommodating the dry batteries is relatively large and difficult to hold and is heavy, and if the use is continued, the batteries need to be replaced. In addition, the ignition position is not so far away from the position of the hand holding the appliance, the hand may become hot during the ignition work, and the remaining amount of the liquefied gas cannot be confirmed because the entire appliance is opaque.

The present invention has been proposed in order to improve the above-mentioned problems with the conventional igniter, and since the ignition position is far away, the hands do not become hot when used, and the remaining amount of the liquefied gas can be easily reduced. The purpose is to provide a household ignition device that can be confirmed and that is excellent in design.

[0006]

[Means for Solving the Problems]

 In order to achieve the above object, the household igniting device according to the present invention accommodates a liquefied gas cylinder in a hand-held housing, and when the trigger member is pressed down, the gas valve is opened and gas is ejected, and a flame is applied to the end of the ignition cylinder. Is a form that issues At this time, it is preferable that the trigger member is disposed below the through hole provided in the housing, and has a shape that allows the trigger member to be easily pushed down. Generally, the flame is generated only when the trigger member is pressed. However, the ignition may be continued by locking the trigger member, or may be a toggle type that repeats firing and extinguishing each time the trigger member is pressed.

In the present invention, the through hole of the hand-held housing is substantially an oval or a vertically long circular flat surface, and the size of the through hole is such that a finger can be inserted with a margin. If desired, the through-hole may be a perfect circular flat surface, or the inner peripheral wall may be partially uneven, and the trigger member may be slightly offset from the lower portion of the through-hole.

In the ignition device of the present invention, the tube communicating with the gas cylinder extends through the housing through the gas valve to the metal nozzle inside the ignition tube. This tube is usually a flexible vinyl tube, and can be easily extended from a liquefied gas valve housed in the lower part of the hand-held housing to a nozzle at the tip through a passage near the through hole. It is necessary that the ignition tube be made of metal so that the high voltage generated by the piezoelectric ignition element can be received from the lead wire and flow therethrough to generate a spark inside the ignition tube in front of the nozzle.

In the ignition device of the present invention, the elongated metal ignition tube fixed to the front end of the housing has a length of 60 to 100 mm, preferably around 80 mm. Generally, the longer the ignition cylinder, the better the usability. However, it is necessary to adjust the position of the metal nozzle according to its length, and the length is limited by the gas pressure in the cylinder. In the drawings, the firing tube is straight and can be gently curved or bent as desired.

In the ignition device of the present invention, it is preferable that the gas cylinder and the housing are transparent or translucent, since the amount of liquefied gas can be confirmed from the outside. The housing may have a colored or colored pattern, and only a portion corresponding to the gas cylinder may be transparent or translucent. If the gas cylinder is transparent when the housing is translucent, the amount of internal gas can be easily checked, and if the gas cylinder is colored when the housing is colorless and transparent, the design can be changed.

[0011] Further, the ignition device of the present invention preferably has a non-slip and a step on both sides of the housing, and preferably has a gas injection hole at a lower end of the housing. This non-slip may be composed of a number of parallel ridges that are linear or curved, or may be a suitable dispersion projection or depression, or may be formed on the entire surface of the housing. The gas injection hole of the housing is preferably provided so as to correspond to the gas injection mechanism of the gas cylinder.

[0012]

[Embodiment of the invention]

 Next, the present invention will be described based on embodiments. FIG. 1 shows an ignition device 1 according to the present invention. The ignition device has a total length of, for example, about 20 cm and includes a plastic hand-held housing 2 and a metal ignition tube 3. The half-split type housing 2 is entirely made of translucent hollow plastic, and includes a transparent liquefied gas cylinder 5, a gas valve 7, a vinyl tube 8, a piezoelectric ignition element 10, and a trigger member 12, as shown in FIG. The trigger member is housed in such a manner that the upper portion thereof is exposed to the inside of the inner peripheral wall of the through hole 14 so as to be pressed (see FIG. 1).

The hand-held housing 2 is generally round and elongated, and generally longer than the width of a normal adult hand, for example, about 100 mm long and 40 mm wide. As shown in FIG. 2, the thickness of the housing 2 is slightly larger than that of the ignition tube 3, and is about 20 mm at the thickest point. The housing 2 is provided with a substantially elliptical through hole 14 at the center in the horizontal direction above the plane of the wide portion 13, and the size of the through hole allows a finger to be inserted with a margin. It is about 22 mm. The housing 2 further extends upward in a bar shape from the upper end of the wide portion 13, and the bar portion 15 has a length of, for example, about 37 mm, and most of the rod portion 15 is fitted into the ignition tube 3 (see FIG. 3).

The trigger member 12 is arranged inside the lower part of the through hole 14, and the upper end surface 12a of the trigger member is gently recessed. The trigger member 12 has a horizontally long rectangular side surface, and is slidable vertically along a lower guide mechanism 16. The trigger member 12 opens and closes the valve 7 of the cylinder 5 via the lever 17 by pressing down, and can be fixed by the lateral movement of the lock member 18 (FIG. 1) outside the housing, and the stoppers 19, 19 does not separate from the housing 2.

The liquefied gas cylinder 5 is provided with a flame adjusting lever 20 at the upper side and a gas injection mechanism 22 at the lower end, and a distal end 20 a of the lever 20 is projected outward from the housing 2 in the lateral direction. At the center of the lower end of the housing 2, a notch (not shown) is provided at a position corresponding to the gas injection mechanism 22, and the notch corresponds to a gas injection hole of the housing 2.

The vinyl tube 8 communicating with the cylinder 5 extends upward through the valve 7, through the left passage 23 near the through hole 14 and the housing rod 15, and is connected to the lower end of the metal nozzle 24 fixed to the tip of the housing. Connecting. On the other hand, the two lead wires 25, 25 extend from the piezoelectric ignition element 10 which is hit when the trigger member 12 is pushed down, and the lead wires extend upward through a right passage 26 near the through hole 14. One is connected to the metal nozzle 24 and the other is passed through the housing wall and connected to the fitted metal ignition tube 3.

The half molds 2 a and 2 b (FIG. 2) of the housing 2 are integrated with a cap 28 (FIG. 3) fitted on the tip of the rod-shaped part 15 by an engaging part (not shown) on the inner wall at the lower end. The whole is fixed with two bolts (not shown). The ignition tube 3 having a length of about 80 mm is fitted with the rod-shaped portion 15 of the housing 2, and when fitted, the nozzle 24 is located above the intermediate portion in the ignition tube 3. The ignition cylinder 3 is formed with a V-shaped cut in a part of the upper part thereof, and the V-shaped part 29 (FIG. 2) is folded inward to be used as a spark pin.

In the ignition device 1, when the trigger member 12 is pushed down with a finger, the valve 7 of the cylinder 5 is opened via the lever 17, gas is sent to the nozzle 24 via the tube 8, and the piezoelectric ignition element 10 is simultaneously struck. Then, a high voltage is generated inside the ignition tube 3. As a result, when the trigger member 12 is pressed down, gas is ejected from the tip of the nozzle 24, and a flame can be emitted at the tip of the ignition tube 3. When the finger is released from the trigger member 12, the trigger member rises and closes the valve 7.

As shown in FIG. 1, the hand-held housing 2 has shallow recesses 34 extending downward from below the trigger member 12 on both front and rear surfaces thereof, and a large number of parallel recesses are provided between the recesses and the housing lower end surface. A non-slip 30 as a ridge is provided. In addition, steps 32 are formed on both side walls of the housing 2. The presence of the non-slip 30 and the steps 32 and 32 makes it difficult for even a relatively small person to hold the housing 2 by hand and to push the trigger member 12 easily. Further, the recess 34, the non-slip 30 and the steps 32, 32 change the appearance of the igniter 1 and are excellent in design.

[Effect of the invention]

 Since the ignition device according to the present invention has a long ignition tube of 60 to 100 mm, it is easy to ignite a barbecue or bonfire, the ignition position is farther than the position of the hand holding the device, and the hand becomes hot during the ignition work. There is no. The ignition device of the present invention is safe because there is no danger of inclining at the time of ignition work and burning a hand with a flame, unlike a disposable lighter commercially available.

In the ignition device of the present invention, the gas cylinder and the hand-held housing are transparent or translucent, so that the remaining amount of the liquefied gas can be easily confirmed, and there is no danger that the gas will disappear and the ignition will not occur during use. Gas supply is easy because of the gas injection mechanism. The igniter of the present invention is smaller and easier to hold than a pistol-type igniter, and is lighter because it does not store AA batteries, etc., and does not require battery replacement even if it is used continuously.
