Description

Technical Field

[0001] The utility model specifically relates to a laser cigarette lighter. Background Art

[0002] In life, a cigarette lighter is a small fire-making device, which is mainly used for making fire and smoking, and is also used for cooking and other fire-making. It is indispensable in life.

[0003] The gas used in cigarette lighters is mainly flammable gas. Kerosene was mostly used in the early days. Butane, propane and liquefied petroleum gas are mostly used today. They are pressurized and filled into the gas storage box. Once released into the air, they absorb heat and vaporize and expand rapidly, making them very easy to ignite. This type of cigarette lighting method relies on open flames.

[0004] Some cigarette lighters (lighters) are non-fire cigarette ignition methods, such as arc lighters, heating wire lighters, etc. The heating wire lighter is an electronic excitation device that passes current through the heating wire to generate heat. It uses the heating wire to heat and then ignite the flammable materials near the heating wire. However, this method is easy to touch the heating wire and cause damage to it. The arc lighter uses a high-voltage package to form an arc between two electrodes, and then ignites the flammable materials between the two electrodes. The above two ignition methods will generate a lot of heat, causing the cigarette lighter itself to heat up, such as the heating of the heating wire itself or the heating of the high-voltage package.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0025] As shown in the figure, the utility model provides a laser cigarette lighter, which uses the energy of an energy coherent light beam (such as a laser) to ignite the burning part of a cigarette, and the laser method can avoid the generation of its own heat, making the entire product safer. In addition, the ignition position of the cigarette is set inside the box body, which can also avoid the laser from being emitted outward to cause damage to the user.

[0026] The laser cigarette lighter comprises a box body 1, an ignition chamber 14 arranged in different areas in the box body, a photoelectric sensing device 5 arranged in the ignition chamber, a laser generator 6 and a control circuit board 8. The laser generator and the control circuit board are both arranged outside the ignition chamber, and the beam path of the laser generator is aligned with the ignition area 16 of the ignition chamber, thereby igniting the part of the cigarette to be ignited placed in the ignition area.

[0027] In addition, the laser generator and the control circuit board are fixed in the box through the card slots to ensure that the positions on both sides will not be offset.

[0028] The box body 1 is provided with an opening 11 on any side thereof, and a first switch 3 is provided at any position thereof. The first switch may be a touch switch, a toggle switch, a tactile switch, etc., which is arranged on the surface of the box body for easy operation. The opening is a shape adapted to the cigarette 4 and extends to the inside of the box body. The first switch is directly connected to the control circuit board, and may be directly arranged on the circuit board or connected by wires. If the wire connection is adopted, it can be adjusted according to the position.

[0029] The ignition chamber 14 is placed in the box body and has an ignition area 16, which can be reached through the opening 11; the ignition chamber is independently arranged in the box body and is axial, which is convenient for defining the position of the cigarette and ensuring that the cigarette inserted through the opening can directly reach the ignition area, thereby improving the ignition efficiency.

[0030] The laser generator 6 is arranged in the box body and can generate an energy coherent beam and emit the beam to the ignition area. The laser generator is arranged in the box body at a certain angle so that the beam path of the laser generator is aligned with the ignition area and just aligned with the center of the axis of the ignition chamber. The certain angle is greater than 15°, that is, the beam will not be emitted from the ignition chamber as much as possible to cause damage to the user.

[0031] The photoelectric sensing device 5 is arranged on both sides of the ignition chamber, that is, a groove is arranged on both sides of the ignition chamber, and the light receiver and the light transmitter are respectively arranged in the groove to fix them, and are used to obtain whether the cigarette to be ignited enters the ignition area and output an activation signal. By setting the photoelectric sensing device, when and only when the cigarette enters the ignition area from the opening, the control circuit board is activated, and the laser generator can be started when the first switch is triggered, which plays a protective role.

[0032] The control circuit board 8 is placed in the box body and located outside the ignition chamber. It is electrically connected to the laser generator, the first switch and the photoelectric sensing device respectively. The first switch outputs a control signal to start the laser generator when and only when the photoelectric sensing device outputs an activation signal.

[0033] A battery 7 is provided between the control circuit board and the ignition chamber, and the battery may be a rechargeable battery, so a charging interface may be provided on the control circuit board, and the battery is charged and discharged according to the power management module to achieve repeated use.

[0034] The control circuit board can start the laser generator only when it obtains the signals output by the photoelectric sensing device and the first switch at the same time. The double signal setting has a safety effect.

[0035] The opening, the ignition chamber and the ignition area are located on the same axis and are designed to be linear, which is more suitable for the size of the cigarette and is more convenient to operate.

[0036] The laser generator emits a coherent beam of energy that travels toward the opening and the axis of the ignition chamber.

[0037] An air inlet 13 is provided on any one or both sides of the ignition zone. The air inlet is designed to provide oxygen when the cigarette is ignited and to provide air intake and cooling after the ignition is completed.

[0038] An observation port 12 is provided on one or both sides of the ignition chamber. The observation port is located at the sensing path of the photoelectric sensing device, and it is possible to observe from the outside whether the cigarette is properly inserted.

[0039] An annular baffle 15 is provided between the ignition chamber and the ignition area. The annular baffle has a through hole. When the cigarette hits the annular baffle, the light beam of the laser generator is focused to a focal point adjacent to the through hole plane. The focal point is limited to the ignition area in the ignition chamber. In this way, the end of the cigarette next to the annular baffle will become the point of maximum light intensity, and this light intensity can make the temperature rise to a level sufficient to ignite the cigarette.

[0040] The photoelectric sensing device includes an optical transmitter and an optical receiver arranged relatively to each other, and a channel is formed between the two for the cigarette to pass through. When the cigarette is not inserted, the light beam emitted by the optical transmitter is received by the optical receiver. When the cigarette is inserted between the two, it blocks the light path between the optical transmitter and the optical receiver, thereby causing a signal change in the photoelectric sensing device, thereby judging that the cigarette has been inserted at this time.

[0041] The embodiments should not be regarded as limiting the present invention, but any improvements based on the spirit of the present invention should be within the protection scope of the present invention.
