Description

Technical Field

[0001] The invention relates to an ignition device, in particular to a flamethrower. Background Art

[0002] At present, flamethrowers are usually used for outdoor barbecue, jewelry welding, car maintenance, etc., and the existing flamethrowers generally include a flamethrower body, a main piezoelectric device of the flamethrower body, an ignition switch, a gas chamber and a gas valve assembly thereof. When in use, the piezoelectric cap in the piezoelectric device is compressed by the ignition switch. When the compression stroke reaches the ignition stroke, the piezoelectric device releases high-voltage electrical energy due to the hammer inside the piezoelectric crystal hitting the piezoelectric crystal, and emits electric sparks at the air outlet in the nozzle device through the power generation end connected by the lead wire. While operating the above process, the ignition switch also presses one end of the seesaw, and the other end of the seesaw pushes up the air outlet needle to deflate the air outlet valve, and the released gas meets the electric spark to achieve ignition.

[0003] For safety reasons, most of the current flamethrowers need to be equipped with a safety lock. The safety lock needs to be opened before the ignition operation can be performed, thereby preventing the flamethrower from being used by children or accidents caused by misoperation.

[0004] In addition, since most existing flamethrowers are used for baking or barbecuing, the switch must be pressed all the time during use, and the fire will be kept on, which will make the fingers very tired. Therefore, a fixed fire switch is added to maintain the continuous firing of the flamethrower.

[0005] The safety lock and the fire-fixing switch currently used on the flamethrower are two independent switches, which are complicated to operate. Summary of the invention

[0031] In addition, in the present invention, descriptions such as "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0032] A flamethrower, comprising a flamethrower body, wherein an ignition switch for ignition operation is provided on either side of the flamethrower body, a push button which can be slidably arranged is provided on the flamethrower body, and the bottom of the push button extends to form a limit block, wherein the limit block has a first position for limiting the movement of the ignition switch relative to the flamethrower body, a second position for not forming a limit fit with the ignition switch, and a third position for limiting the movement of the ignition switch in the opposite direction relative to the flamethrower body when the ignition switch is in a pressed state.

[0033] The method of limiting the action of the ignition switch is adopted to realize the switching of locking, operation and ignition setting. For example, the limit block and the ignition switch are matched to form a limit. When the limit block is placed at the lower end of the pressing direction of the ignition switch, the ignition switch in the current state cannot be pressed because it blocks its pressing path. The ignition switch can only be pressed when the restriction is released. When the ignition switch is pressed to ignite, the limit block and the ignition switch are locked to limit the resetting of the ignition switch, thereby completing the ignition setting. Example

[0034] As shown in the figure, the flamethrower body includes a gun body 2, a flamethrower is provided at the front end of the gun body, a nozzle 3 connected thereto is correspondingly provided at the flamethrower, a gripping portion 1 with a built-in fuel storage mechanism is provided at the bottom of the gun body, the ignition switch 5 is hingedly provided on one side of the gun body, and the push button 4 can be slidably provided on the surface of the ignition switch. The ignition switch preferably adopts a hand-pressed handle, one end of which is hinged to the gun body and can be subjected to force to move in the direction of the gun body. A triggering member 51 is provided at the bottom thereof, which can pass through the gun body shell and contact the piezoelectric switch provided in the gun body, that is, by pressing the ignition switch, the piezoelectric switch 6 is triggered. In order to better lock and unlock the ignition switch, the push button 4 is provided on the surface of the ignition switch, that is, a slide groove arranged along the axis of the ignition switch is provided on the ignition switch, and the push button is placed in the slide groove and forms a sliding fit with the slide groove.

[0035] The bottom of the push button extends to form a limit block 73, which is placed in the moving path of the ignition switch relative to the gun body when the push button slides, so as to limit the movement of the ignition switch.

[0036] A stopper 21 having an upper surface and a lower surface is provided on the side opposite to the hinge of the gun body and the ignition switch. The stopper is integrally formed with the shell of the gun body, and the cross section of the stopper is in the shape of a figure 7. That is, when in the first position, the stopper is pressed against the upper surface of the stopper, and its downward path is limited by the stopper, thereby limiting the pressing of the ignition switch.

[0037] When the ignition switch is pressed into place by force, the limit block can be driven by the push button to be placed on the lower side of the limit piece. The upper surface of the limit block contacts the lower surface of the limit piece and is restricted from moving upward, thereby maintaining the force state of the ignition switch and achieving the effect of fixing the ignition.

[0038] Secondly, the lower surface of the limit piece is slightly inclined to facilitate the separation and insertion of the limit block and reduce damping.

[0039] The push button has a first position in which the limit block contacts the upper surface of the limit member and limits the movement of the ignition switch relative to the gun body, a second position in which the limit block does not form a limit fit with the limit member, and a third position in which the limit block contacts the lower surface of the limit member and limits the movement of the ignition switch in the opposite direction relative to the gun body when pressed.

[0040] A tubular structure is formed at the upper rear end of the gun body, one end of the ignition switch is hinged on the front side of the tubular structure, and the rear side of the tubular structure is integrally formed as a limit piece, that is, it has a horizontal portion, and the limit block constitutes a limit in two directions under different conditions with the horizontal portion, namely, a limit from top to bottom and a limit from bottom to top. When the ignition switch is not pressed, the limit block linked to the push button is always located on the upper side of the surface where the horizontal portion is located. Driven by the push button, the limit block can be placed directly above the horizontal portion to limit the downward movement of the ignition switch. When the ignition switch is subjected to force, the limit block is simultaneously driven by the ignition switch to be placed on the lower side of the surface where the horizontal portion is located. Driven by the push button, the limit block can be placed directly below the horizontal portion to limit the upward movement of the ignition switch.

[0041] A linkage piece 7 is provided at the bottom of the ignition switch, one end of which forms a limit block 73. The push button cooperates with the linkage piece. The push button and the linkage piece are designed separately, which can ensure that the push button is fixedly set on the ignition switch.

[0042] The bottom of the ignition switch extends to form a trigger member for performing an ignition operation. The trigger member is arranged through the linkage member and can slide in the through hole of the linkage member, that is, the movement of the linkage member driven by the push button will not affect the triggering action of the ignition switch.

[0043] The linkage part is provided with a through hole, and undercuts 71 are respectively provided on the two symmetrical side walls of the through hole. The bottom of the push button extends to form a buckle 41, and the buckle passes through the ignition switch and forms a snap fit with the undercut. The buckle and the undercut are cooperated to make the two become one, so that the linkage part is not easy to fall off, and the push button is not easy to fall off.

[0044] Two gear slots 72 are provided on the upper surface of the linkage member, and a gear bar 52 adapted thereto is provided on the lower surface of the ignition switch. The design of the gear bar and the gear slots provides a certain hand feel when operating the push button.

[0045] A gas regulating switch 8 is provided at the bottom of the gun body, which is used to adjust the gas output volume, thereby changing the size of the flame. The gas regulating switch includes an adjusting portion that is linked to the gas outlet valve of the fuel storage mechanism 10 and an operating portion for driving the adjusting portion to rotate. The adjusting portion is a circular ring structure with an internal thread on the inner side thereof, which forms a threaded engagement with the gas outlet valve. The gas output volume of the gas outlet valve can be adjusted by rotating the adjusting portion, while the operating portion is an incomplete dial wheel that can be rotatably arranged on one side of the gun body, and the adjusting portion can be driven to rotate by rotating the dial wheel.

[0046] In this embodiment, the operating part 81 and the adjusting part 82 are not arranged in the same plane, that is, the operating part is arranged higher than the adjusting part, and the two are connected by a connecting part 83, and the upper end of the operating part contacts the ignition bracket in the gun body. The bottom of the ignition bracket 9 is provided with a rotating shaft, and the operating part is provided with a rotating shaft hole 84, which is adapted to the rotating shaft. The adjusting part is arranged in linkage with the air outlet valve, and the upper end is pressed by the ignition bracket, thereby ensuring the firmness of its fixation. At the same time, compared with the previous adjustment method using a lever, the contact area of ​​the dial wheel is larger, which is more suitable for operation and more convenient to adjust.

[0047] The embodiments should not be regarded as limiting the present invention, but any improvements made based on the spirit of the present invention should be within the protection scope of the present invention.
