An igniter

Abstract

The present invention adopts an igniter, which is internally provided with a quick exhaust valve device, which includes an exhaust channel that is always in a normally open state, an opening and closing part that can control the opening or closing of the exhaust channel, and a linkage mechanism that can drive the opening and closing part to operate; wherein the air inlet end of the exhaust channel is used for air intake, and the air outlet end extends out of the shell to form an exhaust port; the action of the linkage mechanism drives the opening and closing part to form the closing or opening of the exhaust channel, thereby forming a quick exhaust valve device to quickly exhaust or hold air, and the air duct is connected to the outside air through the exhaust channel. The closing or opening of the exhaust channel should correspond to the opening or closing time node of the gas nozzle. When the igniter is turned off, at the same time as the gas nozzle is closed, the quick exhaust valve device is used to quickly discharge the remaining combustible gas in the air duct along the exhaust channel to the outside of the igniter, thereby accelerating the flame extinguishing speed in the combustion chamber, which is at least 1-3 seconds faster than the extinguishing speed of a conventional igniter, thereby improving the safety factor of the igniter.

Description

Technical Field

[0001] The present invention relates to a smoking article, in particular to an igniter for igniting. Background Art

[0002] The most common igniters in daily life are usually lighters, igniters or cigar flamethrowers. Usually, non-disposable lighters, cigar flamethrowers or igniters are composed of a shell, a gas tank, electronics, a gas nozzle, a rocker, a button, a gas duct and other components. The button is used to drive the rocker to open the gas nozzle to release gas; when it needs to be closed, the rocker is used to close the gas nozzle. However, even if the gas nozzle is closed, there will still be scattered flammable gas in the gas duct. When the combustion is incomplete, there will still be a certain flame, which cannot be quickly extinguished. There are certain safety hazards in use. Summary of the Invention

[0003] The purpose of the present invention is to overcome the defects of the prior art and provide an igniter that is safer to use.

[0004] To achieve the above-mentioned purpose, the present invention adopts an igniter, including a shell, an air storage box, electronics, an air nozzle, a rocker linked to the air nozzle, an air duct, and a quick exhaust valve device is also provided inside the igniter, which includes an exhaust channel that is in a normally open state for a long time, an opening and closing part that can control the opening or closing of the exhaust channel, and a linkage mechanism that can drive the opening and closing part to move; wherein the air inlet end of the exhaust channel is used for air intake, and the air outlet end extends out of the shell to form an exhaust port; the linkage mechanism drives the opening and closing part to form the closure or opening of the exhaust channel, thereby forming a quick exhaust valve device to perform quick exhaust or air-holding action, and the air duct is positively connected to the outside air through the exhaust channel, and the closing or opening of the exhaust channel should correspond to the opening or closing time node of the air nozzle.

[0005] When the igniter is turned off, at the same time as the gas nozzle is closed, the linkage mechanism drives the opening and closing parts to release the closed state of the exhaust channel. The exhaust channel enters a through state, that is, it is connected with the outside air. Because the pressure in the air duct is greater than the outside air, a positive pressure is formed. In this way, the remaining combustible gas in the air duct will be quickly discharged to the outside of the igniter along the exhaust channel, which greatly accelerates the flame extinguishing speed in the combustion chamber, which is at least 1-3 seconds faster than the extinguishing speed of a conventional igniter, greatly improving the safety factor of the igniter.

[0006] The quick exhaust valve device of the present invention can have many structures. The key is that the closing or opening of the exhaust channel should correspond to the opening or closing time node of the air nozzle, such as the following three structures:

[0007] 1. The linkage mechanism is electronic. One end of the electronics presses on one end of the rocker, and the other end of the rocker forms the opening and closing member. Any section of the exhaust passage is placed below the tail end of the rocker. When the electronics actuate to drive the rocker in linkage, the rocker presses on the exhaust passage to close it; when the electronics reset, they drive the rocker in linkage, and the rocker releases the pressure on the exhaust passage, and the exhaust passage opens for rapid exhaust.

[0008] This structure utilizes the conventional internal structure of the igniter to arrange this rapid exhaust valve device. Only an exhaust passage needs to be added, and the rocker is used as the opening and closing member, without the need to additionally add other components, with low cost and easy to implement.

[0009] Among them, the exhaust passage is a section of exhaust pipe, shaped like a U and lying horizontally. The intake end of the exhaust pipe is connected to the air nozzle, and the other end, the outlet end, is placed below the tail of the rocker.

[0010] Such a layout is suitable for igniters with the exhaust port set on the housing near the gas storage tank or the air nozzle. The electronics are in direct contact with the rocker, and the shape and installation position of the exhaust pipe facilitate arrangement and exhaust.

[0011] 2. An ignition button is also provided on the housing of the igniter. The linkage mechanism is the ignition button. Any section of the exhaust passage is adjacent to the electronics. An opening and closing member is formed on the side of the electronics close to the exhaust passage. When the ignition button acts to drive the electronics in linkage, the electronics press on the exhaust passage to close it; when the ignition button resets, the electronics also reset, releasing the pressure on the exhaust passage, and the exhaust passage opens for rapid exhaust.

[0012] This structure utilizes the conventional internal structure of the igniter to arrange this rapid exhaust valve device. Only an exhaust passage needs to be added, and the electronics are used as the opening and closing member, without the need to additionally add other components, with low cost and easy to implement.

[0013] Among them, the electronics are horizontally arranged inside the igniter housing. The exhaust port of the rapid exhaust valve device is set at the upper end of the electronics. The exhaust passage is a section of exhaust pipe. The intake end of this exhaust pipe is connected to the air nozzle, and the other end passes through below the button on the electronics and is fixed to the exhaust port. The button on the electronics forms the opening and closing member, and with the horizontal pressing or resetting of the button, it constitutes the pressure on or the release of the pressure on the exhaust pipe.

[0014] This is because it is considered that the exhaust ports of some igniters are suitable to be set above the electronics. In order to be more conducive to the internal layout of the igniter and convenient for exhaust, the horizontally arranged electronics are used as the opening and closing member.

[0015] 3. The linkage mechanism is independently arranged on the shell and exposed to the shell to form an on / off key. The other end of the on / off key is used to press the opening and closing part inside the igniter. When the on / off key is actuated, the opening and closing part drives the opening and closing part to press the exhaust channel to close it. When the on / off key is reset, the opening and closing part is also reset, releasing the pressure on the exhaust channel, and the exhaust channel is opened for rapid exhaust.

[0016] The quick exhaust valve device of this structure is a device in which an additional switch key is added to the shell to independently control the opening and closing of the quick exhaust valve device.

[0017] The connection between the exhaust channel and the air duct of the present invention can have the following three structures:

[0018] 1. The exhaust channel is connected to the upper end of the air duct, close to the combustion furnace.

[0019] 2. The exhaust channel is connected to the lower end of the air duct, close to the air nozzle.

[0020] 3. The exhaust channel and the air duct are connected with a three-way valve.

[0021] The above three connection methods are suitable for lighters with different internal layouts. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Figure 5 This is a schematic diagram of the internal structure of an igniter according to embodiment 2 of the present invention; DETAILED DESCRIPTION

[0027] like Figures 1 to 4As shown, embodiment 1 of the present invention is a conventional lighter, which consists of a shell, an ignition button 7, a gas storage box 1, an electronic device 2, a gas nozzle 3, a rocker 4 linked to the gas nozzle 3, an air guide tube 5, an exhaust pipe 6 and other components. The exhaust pipe 6 is U-shaped and arranged horizontally. The air inlet end 61 of the exhaust pipe 6 is connected to the gas nozzle, and the air outlet end 62 at the other end is located below the tail 41 of the rocker 4. The exhaust port is arranged on the shell near the gas nozzle 3, one end of the rocker 4 is pressed on the protrusion at the lower end of the electronic device 2, the middle part of the rocker 4 is linked to the gas nozzle 3, and the tail end of the rocker 4 is located above the air outlet end 61 of the exhaust pipe 6. When the electronic device 2 moves, the rocker 4 is linked, and the rocker 4 presses the exhaust pipe 6 to close it; when the electronic device 2 is reset, the rocker 4 is driven to link, and the rocker 4 releases the pressure on the exhaust pipe 6, and the exhaust pipe 6 is opened. The remaining gas in the air guide tube 5 is quickly exhausted through the exhaust port, discharged from the lighter, and into the outside air, so that the flame in the combustion chamber loses fuel support and is quickly extinguished.

[0028] like Figure 5 As shown, embodiment 2 of the present invention is an unconventional lighter, in which the electronic part 4 of the lighter is arranged horizontally in the lighter housing, the exhaust port of the quick exhaust valve device is arranged at the upper end of the electronic part 4, and the exhaust channel is a section of exhaust pipe 6. The air inlet end 61 of the exhaust pipe 6 is connected to the air nozzle 3, and the other end 62 passes under the button 21 on the electronic part 2 and is fixed on the exhaust port. A protrusion 211 is formed on the button 21 on the electronic part 2 toward the exhaust pipe 6, which serves as an opening and closing part. As the button 21 is pressed horizontally or reset, the protrusion 211 compresses or releases the exhaust pipe 6.

[0029] The quick exhaust valve device of the present invention can have many structures, not only the above two embodiments. It can also be considered to adopt a linkage mechanism independently set on the shell and exposed to the shell to form an open key. The other end of the switch key is used to press the opening and closing member inside the igniter. When the switch key is actuated, the opening and closing member is linked, and the opening and closing member presses the exhaust channel to form it closed; when the switch key is reset, the opening and closing member is also reset, releasing the pressure on the exhaust channel, and the exhaust channel is opened for rapid exhaust.

[0030] Such a quick exhaust valve device can be used on various igniters, not just lighters, but also cigar flamethrowers or igniters. As long as the method of igniting and burning by exhausting gas and then closing the exhaust gas to extinguish the flame is adopted, the key core is to add a quick exhaust valve device, and the closing or opening of the exhaust channel should correspond to the opening or closing time node of the gas nozzle 3. This correspondence means that when the igniter needs to ignite, while the gas nozzle 3 is opened to discharge gas, the exhaust channel must be closed to prevent gas from being discharged from one side of the exhaust channel; when the igniter is turned off and the gas nozzle 3 is closed, the exhaust channel must be opened immediately to allow the gas in the gas nozzle 3 or the air duct 5 to be quickly discharged from one side of the exhaust channel.

[0031] The exhaust pipe 6 in Implementation 1 or Implementation 2 is connected to the air nozzle 2. The exhaust pipe 6 can also be directly connected to the air guide pipe 5. The connection between the exhaust passage of the present invention and the air guide pipe 5 can have the following three structures:

[0032] 1. The exhaust passage is connected to the upper end portion of the air guide pipe 5, near the combustion furnace side.

[0033] 2. The exhaust passage is connected to the lower end portion of the air guide pipe 5, near the air nozzle 3 side.

[0034] 3. The connection between the exhaust passage and the air guide pipe 5 is connected by a three-way valve.
