Description

[Technical field]

[0001] The present invention relates to an ignition device, and more particularly to an ignition device that has a simple configuration, is easy to operate, and ensures a high level of safety. [Background technology]

[0002] Conventional ignition devices are disclosed in, for example, Patent Documents 1 to 4. The folding igniter described in Patent Document 1 comprises a main body having a fuel tank, a piezoelectric unit, and an operating member, and a rotating arm portion rotatable relative to the main body. The folding igniter is provided with a locking mechanism, which prevents the operating member from being pushed in when the opening angle of the rotating arm portion is equal to or less than a predetermined angle. The locking mechanism includes a thick portion provided on a part of a cylindrical wall that is concentrically arranged around the rotation axis of the base of the rotating arm portion, and a hook portion provided on the operating member. When the opening angle of the rotating arm portion is greater than a predetermined angle, the thick portion and the hook portion do not interfere with each other, and the operating member can be pushed in to ignite the fire, but when the opening angle of the rotating arm portion is equal to or less than the predetermined angle, the thick portion and the hook portion interfere with each other, making it impossible to push in the operating member.

[0003] The multi-mode lighter described in Patent Document 2 has a wand assembly rotatably mounted in a housing, and a cam that rotates together with the wand assembly. The multi-mode lighter is equipped with a cam follower that operates in conjunction with a trigger for ignition operation and is pressed against the cam, and the cam and cam follower ensure that the ignition trigger cannot be pressed in unless the wand assembly is opened beyond a predetermined angle.

[0004] The ignition device described in Patent Document 3 has a flame nozzle rod section with a flame nozzle at its tip that is rotatably mounted relative to the main body section, and normally the tip of the lock lever is pressed against the pivot base and the rotation of the flame nozzle rod section is restricted by frictional force; however, when the lock lever is operated, the restriction on the rotation of the flame nozzle rod section is released and the lock section of the lock lever engages with the ignition lever, restricting the ignition operation using the ignition lever.

[0005] The folding safety lighter of Patent Document 4 has a rotatable extension tube attached to a housing in which a push button is installed. When not in use, the folding safety lighter is folded up, with the extension tube covering the push button. When in use, the extension tube is rotated to expose the push button and enable ignition. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] JP 2007-64605 A [Patent Document 2] Special Publication No. 2006-524310 [Patent Document 3] JP 2005-140475 A [Patent Document 4] Japanese Patent Application Laid-Open No. 60-122828 Summary of the Invention [Problem to be solved by the invention]

[0007] The above conventional configuration has the following problems. In the folding ignition device of Patent Document 1, the cylindrical wall around the pivot shaft and the hooks have a complex structure. The multi-mode lighter of Patent Document 2 employs a structure using a cam, which results in a complex structure. The ignition device of Patent Document 3 requires the operation of a lock lever, which is cumbersome. In the folding safety lighter of Patent Document 4, the user can still ignite the lighter even when his or her hand is close to the tip of the extension tube, so safety cannot be said to be guaranteed reliably.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] A first embodiment of the present invention will be described below with reference to FIGS. 1 to 5. FIG. As shown in Figures 1 to 3, the ignition device 1 according to the first embodiment has a main body case 3. As shown in Figure 2, a fuel tank 5 is placed in the main body case 3. The fuel tank 5 is filled with fuel 7. A nozzle 9 is provided on the upper side of the fuel tank 5 in FIG. 2. A valve 11 is provided on the lower side of the nozzle 9 in FIG. 2. A valve 13 is provided on the lower side of the valve 11 in FIG.

[0013] A piezoelectric device 15 is installed inside the main body case 3 and to the right of the fuel tank 5 in Fig. 2. A piezoelectric device switch 17 is provided above the piezoelectric device 15 in Fig. 2. The piezoelectric device switch 17 is normally biased upward in Fig. 2 by an elastic member (not shown) inside the piezoelectric device 15, but can be pushed downward in Fig. 2 against the elastic force of the elastic member (not shown). When the piezoelectric device switch 17 is pushed down, a high voltage can be generated by the piezoelectric device 15.

[0014] An ignition button 21 is provided on the upper side of the piezoelectric device switch 17 in Fig. 2 so as to be movable in the up and down direction in Fig. 2 relative to the main body case 3. The lower side of the ignition button 21 in Fig. 2 abuts against the tip (upper end in Fig. 2) of the piezoelectric device switch 17, so that the ignition button 21 can press down the piezoelectric device switch 17. For example, as shown in Figures 3(a) and 3(b), an ignition button side engaging protrusion 23 is formed on the left side of the ignition button 21 in Figure 3(a). The ignition button side engaging protrusion 23 is a cylindrical protrusion.

[0015] A gas lever 25 is rotatably installed in the main body case 3. As shown in Fig. 3, when the ignition button 21 is pressed down, the right end of the gas lever 25 in Fig. 3 is urged downward in Fig. 2, and the left end of the gas lever 25 in Fig. 3 is pushed up. The left end of the gas lever 25 in Fig. 3 abuts the lower side of the nozzle 9 in Fig. 3, and when the ignition button 21 is pressed down in Fig. 3, the nozzle 9 and the valve 11 are pulled up in Fig. 3, the valve 13 is opened, and the fuel 7 in the fuel tank 5 is discharged from the nozzle 9. When the ignition button 21 is pushed up in Fig. 3 by an elastic member (not shown) in the piezoelectric device 15 via the piezoelectric device switch 17 to the non-use state, the valve 13 is closed by an elastic member (not shown) to stop the discharge of the fuel 7 from the fuel tank 5.

[0016] A combustion cylinder case 31 is rotatably installed on the upper left side of the main body case 3 in Fig. 2. A gas discharge member 33 is installed on the tip side (lower side in Fig. 2) of the combustion cylinder case 31. The gas discharge member 33 and the nozzle 9 are connected by a gas conduit 35 which is a flexible tube, so that the gas 7 discharged from the nozzle 9 is discharged from the gas discharge member 33.

[0017] Further, a discharge terminal 37 is provided near the gas discharge member 33. The discharge terminal 37 and the piezoelectric device 15 are electrically connected by a piezoelectric lead wire 39, and a spark is generated at the tip of the discharge terminal 37 by the high voltage generated by the piezoelectric device 15, so that the gas 7 discharged from the gas discharge member 33 can be ignited and burned.

[0018] 2, for example, a rotating shaft portion 41 is provided on the base end side (upper side in FIG. 2) of the combustion cylinder case 31. The rotating shaft portion 41 passes through a through hole 43 provided in the main body case 3, and an enlarged flange portion 45 is provided on the right side of the rotating shaft portion 41 in FIG. 2, so that the combustion cylinder case 31 does not fall off from the main body case 3.

[0019] For example, as shown in Fig. 4(c) and Fig. 4(d), an ignition button operation restricting portion 51 is provided on the inside side of the rotating shaft portion 41 of the main body case 3 (the right side in Fig. 4(c)). The ignition button operation restricting portion 51 is formed with a rotating shaft side engaging recess 53 that opens on the ignition button 21 side (the right side in Fig. 4(c)). For example, as shown in Fig. 4(d), the rotating shaft side engaging recess 53 is a linear groove that is approximately the center of rotation of the rotating shaft portion 41 and extends from the position of the ignition button side engaging protrusion 23 when the ignition button 21 is not in use toward the outer periphery of the rotating shaft portion 41.

[0020] When the ignition device 1 is not in use as shown in Figures 3(a) and 5(a), the ignition button side engagement protrusion 23 is located on the end side of the pivot shaft side engagement recess 53, and the ignition button 21 is restricted from being pressed downward in Figure 5(a). When the ignition device 1 is used as shown in Figures 3(b) and 5(b), the combustion cylinder case 31 is rotated 180 degrees upward from the non-use state shown in Figure 5(a), the pivot shaft side engagement recess 53 is directed downward in Figure 5(b), and there is nothing to hinder the movement of the ignition button side engagement protrusion 23 downward in Figure 5(b), making it possible to press down the ignition button 21 as shown in Figure 5(c).

[0021] Next, the operation of the first embodiment will be described. First, when the ignition device 1 is not in use, the tip side of the combustion cylinder case 31 is directed downward as shown in Fig. 1(a) and Fig. 2. In this state, as shown in Fig. 5(a), the end of the rotary shaft side engagement recess 53 is located below the ignition button side engagement protrusion 23, and the pressing operation of the ignition button 21 is restricted.

[0022] To put the ignition tool 1 into a usable state, the combustion tube case 31 is rotated 180 degrees upward to the state shown in Fig. 1(a) or Fig. 3(a). In this state, as shown in Fig. 5(b), there is an internal space of the rotation shaft side engagement recess 53 below the ignition button side engagement protrusion 23, and the depression of the ignition button 21 is not restricted. Here, when the ignition button 21 is depressed to the state shown in Fig. 3(b) or Fig. 5(c), the valve 13 is opened by the gas lever 25, the fuel 7 in the fuel tank 5 is released from the gas release member 33, and the piezoelectric device 15 discharges at the tip of the discharge terminal 37, and the combustion of the fuel 7 begins.

[0023] When the ignition button 21 is no longer pressed down, the elastic force of an elastic member (not shown) causes the ignition button 21 to return to its original position, the valve 13 closes, the release of fuel 7 from the fuel tank 5 is stopped, and the combustion of the fuel 7 at the tip side of the gas release portion 33 is stopped.

[0024] Next, the effects of the first embodiment will be described. An ignition button 21 is provided with an ignition button side engaging protrusion 23, and a pivoting shaft side engaging recess 53 is provided on the pivoting shaft portion 41 side of the combustion cylinder case 31. When the ignition button 21 is not in use, the movement of the ignition button 21 is restricted by the pivoting shaft side engaging recess 53 and the ignition button side engaging protrusion 23. When the combustion cylinder case 31 is rotated from the non-use state to the use state, the direction of the pivoting shaft side engaging recess 53 changes, the restriction on the movement of the ignition button 21 by the ignition button side engaging protrusion 23 is released, and ignition operation by the ignition button 21 becomes possible. Therefore, the simple configuration makes it easy to operate and ensures a high level of safety.

[0025] Furthermore, the rotation shaft side engaging recess 53 is a linear groove, and the ignition button side engaging protrusion 23 is a substantially cylindrical protrusion, so that the structure is simpler.

[0026] Hereinafter, a second embodiment of the present invention will be described with reference to FIG. The ignition device in the second embodiment has a configuration similar to that of the ignition device 1 in the first embodiment described above, but has a rotating shaft side engagement recess 101 that is oriented diagonally upward (for example, in a direction inclined 30 degrees from the vertical) when not in use, as shown in Fig. 6(a). Therefore, in the case of the first embodiment described above, the combustion cylinder case 31 is rotated 180 degrees from the non-use state to the use state, but in this second embodiment, the combustion cylinder case 31 can be set to the use state as shown in Fig. 6(b) without being vertical (for example, by rotating 150 degrees).

[0027] In the case of the second embodiment as well, the simple configuration allows for easy operation and ensures a high level of safety.

[0028] Hereinafter, a third embodiment of the present invention will be described with reference to FIG. The ignition device in the third embodiment has a configuration similar to that of the ignition device 1 in the first embodiment described above, but as shown in Fig. 7(a), linear engagement recesses 201, 203 on the rotary shaft side are formed to intersect at right angles. Therefore, the ignition device can be used not only in a state in which the combustion cylinder case 31 is oriented vertically upward as shown in Fig. 7(b), but also in a state in which the combustion cylinder case 31 is oriented horizontally as shown in Fig. 7(c).

[0029] In the case of the third embodiment, the simple configuration also ensures easy operation and high safety. Also, the orientation of the combustion cylinder case 31 in the usage state can be arbitrarily selected from two directions, the vertical direction and the horizontal direction.

[0030] It should be noted that the present invention is not limited to the first and second embodiments. Various cases are possible for the number, shape, angle, etc. of the pivot shaft side engaging recesses. Also, various cases are possible for the angle and number of orientations of the combustion casing in a usable state. In addition, the illustrated configuration is merely an example, and various other cases are possible. [Industrial Applicability]

[0031] The present invention relates to an ignition device, and in particular to an ignition device that has a simple configuration, is easy to operate, and ensures a high level of safety, and is suitable for use as a cigarette lighter, for example. [Explanation of symbols]
