TECHNICAL FIELD
[0001] The utility model relates to laser cigarette lighter technical field especially relates to a laser cigarette lighter of preventing laser emission. BACKGROUND
[0002] In daily life, people often use various cigarette lighters to ignite cigarettes. With the development of science and technology, laser cigarette lighters gradually attract attention due to their energy-saving, environmental protection, long service life, windproof and other advantages. Laser cigarette lighters can accurately focus laser light on a specific part of the tobacco to ignite it, which not only reduces unnecessary tobacco loss, but also avoids the burnt taste caused by the spread of open flames around. However, the existing laser cigarette lighters also have some problems in use, such as if the laser is not turned off in time after igniting the cigarette, it will directly irradiate the human body, and the excessive power may cause laser radiation injury. Moreover, due to the small size of the laser beam spot, accurate alignment is required, and the existing laser cigarette lighters are not easy to align the cigarette, which increases the cigarette lighting time and reduces the use effect.
[0003] In the existing laser cigarette lighter, in order to prevent laser radiation, a common protective measure is to make the cigarette lighting cavity into a cylindrical shape, and the cigarette is inserted into the cigarette lighting cavity for lighting. The laser is blocked and absorbed in the cigarette lighting cylinder, and cannot radiate to the outside of the cigarette lighting cylinder. However, this method has obvious defects, as it cannot achieve accurate laser alignment of the cigarette, because the cigarette is not well fixed and positioned in the cigarette lighting cylinder, which makes the laser unable to effectively focus on the fixed position of the tobacco, thereby increasing the cigarette lighting time. In addition, if the cigarette cannot be aligned with the specific position in the cigarette lighting cylinder, it may also directly contact the inner wall of the cigarette lighting cylinder, causing pollution.

[0026] It should be noted that the following detailed description is exemplary and is intended to provide further explanation of the present application. Unless otherwise specified, all technical and scientific terms used in the present application have the same meaning as generally understood by those skilled in the art to which the present application belongs. In addition, it should be understood that when the terms "comprise" and / or "include" are used in the present specification, they indicate the presence of a feature, step, operation, device, component and / or their combination.
[0027] As shown in Figure 1 , Figure 2 , in view of the problems of laser radiation injury and difficulty in aligning the cigarette 3 with the laser, which results in long cigarette lighting time, the present embodiment provides a laser cigarette lighter capable of preventing laser emission, which comprises a shell 1, a flip cover 2, a laser emission device 6 and a supporting device 4. One side of the flip cover 2 is rotationally connected to one side of the shell 1. The laser emission device 6 is installed in the shell 1 and is arranged obliquely towards the direction of the open-state flip cover 2. A laser emission port 11 is formed in the shell 1, and the rays emitted by the laser emission device 6 can be emitted to the inner side of the open-state flip cover 2 through the laser emission port 11. The supporting device 4 comprises a needle stopper 41 and a cigarette support plate 42. The needle stopper 41 is arranged on the laser emission port 11, and the cigarette support plate 42 is arranged on the side of the laser emission port 11 away from the open-state flip cover 2.
[0028] The shell 1 serves as the shell of the laser cigarette lighter. The shell 1 is provided with a switch button 5 and contains components such as a battery 8, a laser emission device 6 and a circuit board 7, which support the structure of the entire laser cigarette lighter. A lighting port (laser emission port 11) is formed in the shell 1, and the rays emitted by the laser emission device 6 can be emitted through the lighting port.
[0029] The flip cover 2 is connected with one side of the shell 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 to be inclined towards the direction of the flip cover 2 at this time, so that the laser beam can irradiate to the inside of the flip cover 2 through the lighting hole, thereby accurately lighting the cigarette.
[0030] The needle stopper 41 is installed on the lighting hole, and mainly functions to support the cigarette and help align the cigarette with the laser. The cigarette supporting plate 42 is arranged on the side of the lighting hole away from the flip cover 2, and functions to stabilize the position of the cigarette, thereby ensuring that the laser can accurately irradiate to the position of the tobacco for lighting.
[0031] As shown in Figure 3 , the flip cover 2 is arranged with a rotating rod 21, the upper end of the shell 1 is provided with a groove, and the rotating rod 21 of the flip cover 2 is inserted into the groove of the shell 1 and is hinged by a pin shaft. Through the pin shaft hinge, the flip cover 2 can rotate around the pin shaft on the upper end of the shell 1. When the flip cover 2 rotates, the laser emitting device 6 is inclined towards the direction of the flip cover 2 in the open state, and the laser beam can directly irradiate to the inside of the flip cover 2, thereby ensuring that the laser is accurately focused on the cigarette 3 and avoiding scattering of the laser spot.
[0032] As shown in Figure 4 , Figure 5 , the side of the needle stopper 41 facing the cigarette supporting plate 42 is provided with a first supporting surface 413, and the top surface of the cigarette supporting 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 that the end surface of the cigarette stably contacts, thereby avoiding deviation of the cigarette from the alignment position. The second supporting surface 421 is an arc surface, the axis of the arc surface is perpendicular to the first supporting surface 413, the end surface of the cigarette 3 abuts against the first supporting surface 413 of the needle stopper 41, and the second supporting surface 421 is supported on the lower side of the cylindrical surface of the cigarette 3, thereby ensuring that the cigarette does not deviate from the laser path of the laser emitting device 6 when being lit.
[0033] As shown in Figure 5 , the needle stopper 41 includes two L-shaped rods arranged symmetrically with respect to the laser emitting hole 11, the L-shaped rod includes a column 411 and a crossbar 412, the lower end of the column 411 is installed on the shell 1, and the distance between the columns 411 is less than 5 mm, which can effectively resist the cigarette 3, and the crossbar 412 is used to support the end surface of the cigarette 3. Through the design of the L-shaped needle stopper 41, the crossbar 412 can stably support the cigarette 3, so that the cigarette 3 is always kept in the irradiation path of the laser, thereby ensuring that the laser can accurately light the tobacco.
[0034] The column 411 of the needle stopper 41 is parallel to the rays emitted by the laser emitting device 6, or the column 411 and the laser beam form a preset angle, the crossbar 412 intersects the laser beam, ensuring that the laser rays can accurately pass through the ignition port and irradiate the position of the cigarette 3. The cigarette support plate 42 is parallel to the column 411 of the needle stopper 41, or the cigarette support plate 42 and the column 411 form a preset angle, the distance from the upper end of the cigarette support plate 42 to the needle stopper 41 is less than or equal to the distance from the lower end of the cigarette support plate 42 to the needle stopper 41, ensuring that the tobacco can be stably placed and not easily moved during ignition, ensuring the efficiency and accuracy of the ignition process.
[0035] The inclination angle of the rays of the laser emitting device 6 is θ, the vertical distance from the crossbar 412 to the shell 1 is m, the vertical distance from the lowest point of the second supporting surface 421 to the needle stopper 41 is d, and the vertical distance from the lowest point of the second supporting surface 421 to the shell 1 is h, h = d(1-sinθ) / cosθsinθ+m-d+d(sinθ-cosθ) = m+d(1-sinθ) / cosθsinθ-d(1+cosθ-sinθ). Through the design of the inclination angle, the distance between the cigarette support plate 42 and the needle stopper 41, and the height difference, etc., after the cigarette 3 is placed on the cigarette support plate 42 and moves downward to the position of the needle stopper 41, the laser can directly and accurately irradiate the tobacco position of the cigarette 3 to ignite the cigarette.
[0036] The radius of the laser emitting window is r, the distance from the laser emitting window to the end of the flip cover 2 not connected to the shell 1 is f (i.e. the distance from the center of the emitting window to the upper end of the flip cover 2), the length of the flip cover 2 is g (i.e. Figure 2 the distance from the upper end to the lower end of the flip cover 2), and the vertical distance from the laser emitting window to the horizontal line of the end of the flip cover 2 connected to the shell 1 is n (i.e. the height difference between the center of the emitting window and the rotating position of the flip cover 2). When the laser cigarette lighter is placed vertically, the inclination angle θ of the rays of the laser emitting device is arctan(m / r). When the laser cigarette lighter is placed vertically (as shown in Figure 2 The inclination angle θ of the rays of the laser emitting device 6 to the horizontal line is arctan(m / r), and the flip angle α of the flip cover is less than arcsin[(fsinθ+n) / g]. This inclination angle is based on experimental data and engineering design to ensure that the laser beam can effectively irradiate the tobacco position of the cigarette and ignite, without deviating from the target or irradiating other positions, while also meeting the requirements of laser protection, blocking 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, ensuring that the flip cover 2 can effectively block the laser emitting port 11 when it is opened, preventing the laser from emitting outside when the lighter is not in use.
[0037] The horizontal bar 412 has a vertical distance m from the shell 1 greater than or equal to 3 mm and less than or equal to 5 mm, and the ignition port has a radius of 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 on the cigarette 3 and avoid the pollution of the window glass by the lit cigarette. Through the setting of these sizes, the design can enhance the function of the laser cigarette lighter while ensuring its efficient and safe performance.
[0038] The arc surface of the second supporting surface 421 has a diameter greater than or equal to 5 mm and less than or equal to 8 mm. Through such a design, whether it is a thick or thin cigarette 3, it can be stably placed on the tray of the cigarette lighter, avoiding the instability or shaking of the cigarette, which causes the laser to fail 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 fixation of the cigarette during ignition.
[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 of the horizontal bar 412 from the shell 1. In this embodiment, h is 8 mm, which 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 effectively focus on the tobacco part, reducing the waste of laser energy and time delay.
[0040] In summary, based on the existing laser cigarette lighter, the laser light path is rotated outward by a certain angle in this embodiment. By rotating the original laser light path of the laser cigarette lighter by a certain angle, the laser spot is made to hit the cigarette lighter flip cover 2 so that it cannot be directly radiated out, preventing laser radiation injury and improving the safety of the product during use. It can be applied in actual production and life scenes.
[0041] In addition, the existing laser ignition product has only a device similar to the stop pin 41. When lighting a cigarette, the angle at which the cigarette 3 is placed cannot be fixed, the cigarette is easy to shake, the laser cannot effectively focus on the fixed position of the tobacco, which increases the ignition time and reduces the use effect. Moreover, if the cigarette 3 cannot be aligned with the stop pin 41, it is easy to directly contact the window glass sheet, polluting the glass window. In this embodiment, through the cooperation of the cigarette supporting plate 42 and the stop pin 41, and by reasonably and scientifically setting the parameters of the cigarette supporting plate 42 and the stop pin 41, the position of the cigarette 3 can be effectively fixed to achieve rapid ignition, and the cigarette 3 can also be prevented from contacting the window glass to avoid pollution.
[0042] In summary, the laser cigarette lighter has high ignition efficiency and operation convenience, while maintaining high safety.
[0043] The utility model discloses above although the specific embodiment of the utility model has been described in conjunction with the drawing, is not the limit of the utility model protection scope, and the person skilled in the art should understand that on the basis of the technical scheme of the utility model, various modifications or deformation that the person skilled in the art can make without paying creative labour is still within the protection scope of the utility model.
