Description
Technical Field
[0001] The invention relates to the technical field of laser cigarette lighters, and in particular to a laser cigarette lighter capable of preventing laser from emitting outward. Background Art
[0002] In daily life, people often use various cigarette lighters to light cigarettes. With the development of science and technology, laser cigarette lighters have gradually attracted attention due to their advantages such as energy saving, environmental protection, long life, and windproof. Laser cigarette lighters use the characteristics of laser precise focusing to aim the light spot at a specific part of the tobacco for ignition. Compared with the traditional open flame cigarette lighting method, it can not only reduce unnecessary loss of tobacco, but also avoid the burnt smell caused by the open flame spreading to the surrounding area. The accuracy advantage is obvious. However, there are also some problems with the existing laser cigarette lighters during use. For example, after the laser ignites the cigarette, if the laser is not turned off in time, it will directly irradiate the person, and excessive power may cause laser radiation damage. Moreover, since the laser beam spot is small and needs to be precisely aligned, the existing laser cigarette lighter is not easy to align with the cigarette, which increases the lighting time and reduces the use effect.
[0003] In existing laser cigarette lighters, in order to prevent laser radiation, a common protective measure is to make the cigarette lighter cavity into a cylindrical shape, and put the cigarette deep into the cigarette lighter cavity to light the cigarette. The laser is blocked and absorbed in the cigarette lighter tube and cannot be radiated to the outside of the cigarette lighter tube. However, this method has obvious defects. It cannot achieve accurate laser aiming at the cigarette, because the cigarette is not well fixed and positioned in the cigarette lighter tube, resulting in the laser being unable to effectively focus on the fixed position of the tobacco, thereby increasing the lighting time. In addition, if the cigarette cannot be aimed at a specific position in the cigarette lighter tube, it is easy to directly contact the inner wall of the cigarette lighter tube, causing pollution.

[0026] It should be noted that the following detailed descriptions are illustrative and are intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those of ordinary skill in the art to which the present invention belongs. In addition, it should also be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.
[0027] like Figure 1 , Figure 2 As shown, in view of the problems of laser radiation damage in existing laser cigarette lighters and the difficulty in aiming the laser at the cigarette 3, which leads to a long lighting time, this embodiment proposes a laser cigarette lighter that prevents laser from being emitted outward, including: a shell 1, a flip cover 2, a laser emitting device 6 and a supporting device 4; one side of the flip cover 2 is rotatably connected to one side of the shell 1; the laser emitting device 6 is installed in the shell 1 and is arranged obliquely toward the direction of the open flip cover 2, and a laser emitting port 11 is opened on the shell 1, and the rays emitted by the laser emitting device 6 can be emitted to the inner side of the open flip cover 2 through the laser emitting port 11; the supporting device 4 includes a stopper needle 41 and a cigarette support plate 42, the stopper needle 41 is arranged on the laser emitting port 11, and the cigarette support plate 42 is arranged on the side of the laser emitting port 11 away from the open flip cover 2.
[0028] The housing 1 is the outer shell of the laser cigarette lighter. The housing 1 has a switch button 5, and contains components such as a battery 8, a laser emitting device 6, and a circuit board 7 to support the structure of the entire laser cigarette lighter. The housing 1 is provided with an ignition port (laser emitting port 11), and the rays emitted by the laser emitting device 6 can be emitted through the ignition port.
[0029] The flip cover 2 is connected to one side of the housing 1 by rotation, and the flip cover 2 can be opened or closed. When lighting a cigarette, the flip cover 2 is in an open state, and the laser emitting device 6 is arranged tilted toward the flip cover 2 at this time, and the laser beam can be irradiated to the inside of the flip cover 2 through the ignition port, thereby accurately lighting the cigarette.
[0030] The stopper pin 41 is installed on the ignition port, and its main function is to support the cigarette and help it align with the laser. The cigarette support plate 42 is arranged on the side of the ignition port away from the flip cover 2, and plays a role in stabilizing the position of the cigarette, thereby ensuring that the laser can accurately irradiate the part of the tobacco to ignite it.
[0031] like Figure 3 As shown, a rotating rod 21 is arranged in the flip cover 2, and a groove is provided at the upper end of the housing 1. The rotating rod 21 of the flip cover 2 is inserted into the groove of the housing 1 and is hinged by a pin. Through the hinge of the pin, the flip cover 2 can rotate around the pin at the upper end of the housing 1. When the flip cover 2 rotates, the laser emitting device 6 tilts toward the flip cover 2 in the open state, and the laser beam can directly irradiate the inner side of the flip cover 2, ensuring that the laser is accurately focused on the cigarette 3 and avoiding the scattering of the laser spot.
[0032] like Figure 4 , Figure 5 As shown, the side of the stopper needle 41 facing the cigarette support plate 42 is provided with a first supporting surface 413, and the top surface of the cigarette support plate 42 is provided with a second supporting surface 421. The first supporting surface 413 is an inclined surface, and the inclined surface design can ensure stable contact of the end face of the cigarette to prevent the cigarette from deviating from the alignment position. The second supporting surface 421 is an arc surface, and the axis of the arc surface is perpendicular to the first supporting surface 413. The end face of the cigarette 3 is against the first supporting surface 413 of the stopper needle 41, and the second supporting surface 421 is supported on the lower side of the cylindrical surface of the cigarette 3 to ensure that the cigarette will not deviate from the laser path of the laser emitting device 6 when it is ignited.
[0033] like Figure 5 As shown, the stopper needle 41 includes two L-shaped rods symmetrically arranged relative to the laser emission port 11, and the L-shaped rod includes a column 411 and a crossbar 412. The lower ends of the columns 411 are mounted on the housing 1. The distance between the columns 411 is less than 5 mm, which can effectively support the cigarette 3. The crossbar 412 is used to support the end face of the cigarette 3. Through the design of the L-shaped stopper needle 41, the crossbar 412 can stably support the cigarette 3, so that it always remains on the irradiation path of the laser, thereby ensuring that the laser can accurately ignite the tobacco.
[0034] The column 411 of the needle blocking 41 is parallel to the ray emitted by the laser emitting device 6, or the column 411 is at a preset angle with the laser beam, and the crossbar 412 intersects with the laser beam, ensuring that the laser ray can accurately irradiate the part of the cigarette 3 through the ignition port. The cigarette support plate 42 is parallel to the column 411 of the needle blocking 41, or the cigarette support plate 42 is at a preset angle with the column 411, and the distance from the upper end of the cigarette support plate 42 to the needle blocking 41 is less than or equal to the distance from the lower end of the cigarette support plate 42 to the needle blocking 41, ensuring that the cigarette can be stably placed and is not easy to move during the ignition process, ensuring the efficiency and accuracy of the ignition process.
[0035] The inclination angle of the laser emitting device 6 is θ, the vertical distance between the crossbar 412 and the housing 1 is m, the vertical distance between the lowest point of the second supporting surface 421 and the stopper needle 41 is d, and the vertical distance between the lowest point of the second supporting surface 421 and the housing 1 is h, h=d(1-sinθ) / cosθsinθ+m-d+d(sinθ-cosθ)=m+d(1-sinθ) / cosθsinθ-d(1+cosθ-sinθ). By designing parameters such as the inclination angle, the distance between the cigarette support plate 42 and the stopper needle 41, and the height difference, after the cigarette 3 is placed on the cigarette support plate 42 and moved downward to the position of the stopper needle 41, the laser can directly and accurately irradiate the tobacco position of the cigarette 3 to light the cigarette.
[0036] The radius of the laser emission window is r, the distance from the laser emission window to the end of the flip cover 2 that is not connected to the housing 1 is f (i.e. the distance from the center of the emission window to the upper end of the flip cover 2), and the length of the flip cover 2 is g (i.e. Figure 2 The vertical distance between the laser emission window and the horizontal line of the connection end of the flip cover 2 and the housing 1 is n (i.e., the height difference between the center of the emission window and the rotation position of the flip cover 2). When the laser cigarette lighter is placed vertically, the inclination angle θ of the laser emission device is arctan (m / r). When the laser cigarette lighter is placed vertically (e.g. Figure 2 As shown in FIG. 1 , the inclination angle θ between the laser emitting device 6 and the horizontal line is arctan(m / r), and the flip angle α of the flip cover is less than arcsin[(fsinθ+n) / g]. The selection of this inclination angle is based on experimental data and engineering design to ensure that the laser beam can effectively irradiate the tobacco part of the cigarette and ignite it without deviating from the target or irradiating other parts. At the same time, it also meets the requirements of laser protection, and blocks the laser radiation by the flip cover 2 to avoid unnecessary harm to the human body. The flip angle of the flip cover 2 is less than 90 degrees, which ensures that the flip cover 2 can effectively block the laser emission port 11 when it is opened, preventing the laser from being emitted when the cigarette lighter is not in use.
[0037] The vertical distance m between the crossbar 412 and the housing 1 is greater than or equal to 3 mm, d is less than or equal to 5 mm, and the radius of the ignition port is 2.5 mm, so as to ensure that the distance between the laser emitting device 6 and the cigarette 3 supporting device 4 is appropriate, and the angle θ is 70°, which can effectively support the precise alignment of the laser to the cigarette 3 and prevent the lit cigarette from contaminating the window glass. By setting these dimensions, this design enhances the function of the laser cigarette lighter while ensuring its efficient and safe performance.
[0038] The diameter of the arc surface of the second supporting surface 421 is greater than or equal to 5 mm and less than or equal to 8 mm. With such a design, both thick and thin cigarettes 3 can be firmly placed on the tray of the cigarette lighter, avoiding the instability or shaking of the cigarette that causes the laser to be unable to accurately focus on the tobacco. The size design of the arc surface can adapt to the size of most common cigarettes and provide appropriate support force to ensure the fixity of the cigarette during the lighting process.
[0039] The vertical distance h from the lowest point of the second supporting surface 421 to the shell 1 is greater than the vertical distance m from the cross bar 412 to the shell 1. In this embodiment, h is 8 mm. The 8 mm design ensures that the inclination angle of the laser emitting device 6 can accurately match the position of the cigarette 3, so that the laser can be effectively focused on the tobacco part, reducing the waste of laser energy and time delay.
[0040] To sum up, based on the existing laser cigarette lighter, this embodiment rotates the laser light path outward by a specific angle. By rotating the laser light path of the original laser cigarette lighter by a certain angle, the laser spot is hit on the cigarette lighter flip cover 2 so that it cannot be radiated directly, thereby preventing laser radiation damage, improving the safety of the product during use, and can be applied in actual production and life scenarios.
[0041] In addition, the ignition point of the existing laser ignition product is only a device similar to the needle stopper 41. When lighting a cigarette, the angle at which the cigarette 3 is placed cannot be fixed, the cigarette is prone to shake, and the laser cannot be effectively focused on the fixed position of the tobacco, resulting in an increase in ignition time and reduced use effect. Moreover, if the cigarette 3 cannot be aligned with the needle stopper 41, it is easy to directly contact the window glass and pollute the glass window. In this embodiment, by cooperating with the cigarette support plate 42 and the needle stopper 41, and reasonably and scientifically setting the parameters of the cigarette support plate 42 and the needle stopper 41, the position of the cigarette 3 can be effectively fixed to achieve rapid ignition, and the cigarette 3 can be prevented from contacting the window glass to avoid pollution.
[0042] In general, the laser cigarette lighter has high ignition efficiency and easy operation while maintaining a high level of safety.
[0043] Although the above describes the specific implementation mode of the present invention in conjunction with the accompanying drawings, it is not intended to limit the scope of protection of the present invention. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art on the basis of the technical solution of the present invention without creative work are still within the scope of protection of the present invention.
