Description of the invention: [Technical field of the invention] The invention is a phase-type misplaced safety hitting city, _ means that the height of the pressing portion is increased at the end of the cross bar, and the horizontal distance between the secret point and the straight surface of the supporting surface Fixed, so that the thumb rotates the grinding wheel to rotate the distance, angle, and speed, resulting in the friction wheel to reduce the spark and not easy to ignite the gas, and the angle of inclination formed by the relative position of the fulcrum and the lever applying point becomes larger, then the lever Not only can it not be painful, but the effort is to make it easier for the younger person to use the lighter to ignite the lighter but still within the range of the user's ability to achieve the safe use of the lighter to prevent children from igniting. [Prior Art] Simple lighters bring considerable convenience and cost reduction to consumers. It is a big breakthrough in the history of modern material civilization since humans have used fire for thousands of years. Safety protection also creates a big worry. Especially when young children play with a lighter, it is likely to cause a fire. The so-called "star fire can cure the original", and the lighter can not be used inadvertently. Fig. 1 is an exploded perspective view showing the structure of a conventional simple type lever type lighter, and Fig. 2 is a plan half cross-sectional view of a known simple type lever type lighter. Early lighter structure As shown in Figs. 1 and 2, a lever type lighter is composed of a main body, a top cover 2, a grinding wheel 3, a fire cover 4, and a lever 5. The body 1 is a hollow body for filling the liquid gas of the ignition fuel of the lighter, and the closing portion 11 is fixed thereon. The closing portion u is provided with a burner base 12 having a tooth 121 and a 201015030 and having a neck. The burner 13 of the portion 131; the top cover _ above the closed (four) of the body i corresponding thereto, and the center of the job 2 is provided with - _ 22, the content of which is set to an elastic cyanine 32 and - flint 31 ' and its sides extend Two grinding wheel seats facing each other and the upper end of the grinding wheel seat 21 are respectively provided with fixing holes 2Π, and a fixing hole batch is also arranged at the lower end thereof, and the top cover 2 has an adjustment (4), and the inner surface has an inner surface. The arranging teeth 231 ′ can be sleeved on the fire nozzle 13 corresponding to the nozzle holder 12 and combined with the outer row teeth 121 (four) of the outer surface thereof for adjusting the gas outflow amount in the body 1; the crowbar ^ includes a pressing The base portion 52 and the sleeve hole 53 are respectively disposed on both sides of the base 52, and the convex portion 521 is used as a fulcrum c of the lever 5 (shown in FIG. 2). The convex portion 521 is sleeved on the grinding wheel base. The fixing hole 212 at the bottom of the 21, and the fixing hole is used as a fulcrum bearing to receive the convex portion 521. The sleeve hole 53 used as the resistance point of the lever 5 (see Fig. 2) passes through the burner 13 on the closing portion 11 and is inserted into the neck portion 13 of the lever 5 at the end of the lever 5. 51 ^ is used as the point of force A of the damage rod 5 (ie, the point of application p ' is the same as the second picture), and then the fire cover 4 is set on the outermost part to form the most widely used simple type of lever before the target. lighter. Figure 2 is a plan half-sectional view of the conventional simple type of type of lighter, when the horizontal position of the lever 5 from the fulcrum c to the point of application p (i.e., the point of application a) is inclined upward, and the point of application is Ρ The horizontal height is exactly higher than the outer diameter of the lowest point of the new core in the vertical direction of the grinding wheel 3, and the horizontal distance between the applied point Ρ and the vertical center line of the fulcrum C is a fixed value, and the fulcrum C is located adjacent to the vertical center line of the grinding wheel 3 Where, from the point of application ρ to the tangent height of the highest point of the center line of the grinding wheel 3 Η"; when used, the user presses the lever 5 with the thumb 20101530 before pressing the point p of the pressing portion 51, first by the center of the grinding wheel 3 The high speed of the vertical point of the line is rotated clockwise to drive the grinding wheel 3, so that the grinding wheel 3 and the flint 31 rotate and rub to generate a large amount of sparks. When the thumb moves down to contact the point P of the lever $, the lever 5 The gas burner 13 is then pulled up and the gas stored in the body is released, and the gas is simultaneously ignited by the spark to generate a flame. The simple lighter is located at the bottom of the outer diameter of the grinding wheel 3 due to the point of application of the pressing portion 51. Below, and its fulcrum C and The angle of inclination υ' formed by the horizontal tangential line of the outer diameter of the wheel 3 is closer to zero, and the angle of rotation of the point of application P to the highest point of the center line of the grinding wheel 3 is larger, so the rotation distance of the thumb to drive the grinding wheel 3 is higher. Large, when the user rotates the grinding wheel 3 quickly, 'the inclination angle 此 of the pressing portion 51 is smaller (ie, the rotation angle is larger)', the larger the contact distance between the grinding wheel 3 and the flint 31, the greater the spark generated. Second, the distance from the point of application to the point C of the fulcrum C, the tilting, and the smaller, according to the Petri's theorem, the lower the height of the horizontal tangent to the point of the fulcrum c, the lower the height of the tangential point c, the lower the chord of the triangle The shorter, the effect of the lever force point ρ against the force point β can be more labor-saving and easy to release gas and ignite, so in general, the child is often caused by playing a lighter without a crisis consciousness. This is a shortcoming of the conventional simple type of stick lighter. [Disclosure] In view of the shortcomings of the above-mentioned common techniques, the main object of the present invention is to provide a method of reducing the safety and increasing the amount of money and the height of the support. User's thumb _ rim wheel _ small, and the angle of inclination formed by the relative position of the force point and the fulcrum level 201015030 line becomes larger, so as to reduce the distance, angle and speed of the grinding wheel rotation 'reducing the amount of spark generated' makes it difficult for young children The lighter will be ignited by the lighter's but it is still within the range of the general user's force, and the height H' of the pressing point of the pressing portion of the lever is the lowest point of the horizontal tangent of the vertical centerline diameter of the grinding wheel up 1/3* η *Between 2/3, 'the distance that the thumb rotates the grinding wheel becomes smaller; also, the higher the height of the pressing point of the pressing part, the larger the inclination angle formed by the relative position of the applied point and the fulcrum, then the point of application The smaller the rotation angle with the highest point of the vertical center line is, the vertical distance between the force application point and the fulcrum point is fixed, and the inclination angle formed by the relative position of the force application point and the fulcrum point is larger, the lever can not only save labor but effort, so Achieve safety in use. To achieve the above object, the dislocation safety lighter of the present invention comprises: a body, a top cover, a grinding wheel, a fire cover, and a lever; the lever includes an ink pressing portion, a base, and a set of holes in the base A convex portion is arranged on each side as a fulcrum of the lever, and the convex portion is sleeved on the surface of the filament portion, and the fine hole is used for the fulcrum as the fulcrum bearing seat, and the cover is With the occupation of the ton of overgrinding wheel and crossbar, where 'the lever-the point of the force of the part is at a height ^ with the horizontal line of the lever, the height Η is the lowest point of the vertical centerline diameter of the grinding wheel up to the point of application of the pressing part The horizontal tangent height-distance is in the range of the vertical point of the vertical centerline diameter of the grinding wheel up 1/3* Η * 2/3 between the 'height' pressing point and the relative position of the fulcrum. Shili _ grinding wheel vertical towel core, the lower the rotation angle of the highest point of the line, the smaller the rotation distance of the user's thumb to drive the grinding wheel, the smaller the speed and angle of the grinding wheel 201015030 and the flint, so that the spark generated by the grinding wheel is not enough to ignite Gas, when the point of force and The distance between the horizontal tangent of the vertical centerline is fixed, and the inclination of the applied point and the fulcrum is more than A. According to the fresh theorem, the lever can not only save labor but effort, but although the enemy fire The crossbar of the machine is laborious', but its swirling force is still within the range of the user's ability, so it can improve the safe use of the lighter. In order to enable the reviewing committee to have further understanding and understanding of the features, objects and functions of the present invention, the detailed description is as follows: [Embodiment] «Monthly Referring to FIG. 3 is a lighter of a preferred embodiment of the present invention. The knot is broken down, as can be seen from the figure. · The age of the age includes: the body top cover 2, the grinding wheel 3, the fire cover 4, and the lever 5; wherein the body top cover 2, the grinding wheel 3, and the fire cover 4 Both the conventional and the four-type lever type lighter structure shown in the figure are not mentioned here.杠杆 The lever 5 includes: a pressing portion 5 - a base 52 and a set of holes 53 , and a convex portion 521 is provided on both sides of the base 52 as a fulcrum c of the lever 5 (the same as the fourth, fifth) The convex portion 521 is sleeved on the fixing hole 212 at the bottom of the grinding wheel base 21, and the fixing hole 212 is used as a fulcrum bearing to receive the convex portion 521, and is used as a resistance point of the damaged rod 5. B (the same as the fourth and fifth figures), the fitting hole 53 is fitted into the neck portion 131 by the burner 13 on the closing portion u, and the pressing point P of the pressing portion 设置 provided at one end of the lever 5 is used.

The rotation distance is 'when the user's thumb drives the grinding wheel 3 The smaller the rotation distance, the slower the action speed of the grinding wheel 3 and the flint 31, and the smaller the angle of action. The spark generated by the friction between the grinding wheel 3 and the flint gas μ is insufficient to ignite the gas, thereby improving the safety of the lighter for preventing child ignition. . Figure 5 is a plan view, partly in section, of the second embodiment of the present invention. In the second reference embodiment of the present invention, the pressing point of the pressing portion 51 is Η, the diameter of the grinding wheel 3 is Η, and the vertical center line is the lowest. The horizontal tangential point is two-thirds upward, and the fulcrum c is located adjacent to the vertical center line of the grinding wheel 3, and the horizontal distance between the urging point ρ and the vertical center line of the fulcrum c is set to a fixed value 'and the point of force and the fulcrum The larger the inclination angle c formed by the relative position of c, the more the height Η' of the horizontal tangent to the fulcrum c is higher, the longer the chord of the triangle will be. The labor effort is more laborious; in addition, the rotation angle 为 is the rotation distance of the user's thumb from the highest point of the straightening diameter of the grinding wheel 3 to the 15015030 to the pressing point of the pressing portion 51. When the user's thumb drives the rotation of the grinding wheel 3 The smaller the distance, the smaller the speed of the grinding wheel 3 and the flint, and the smaller the 彳_degree. The effect of the wheel 3 and the flint and the illusion of the flakes is enough for the gas to be used. According to the fifth [Fig. 5, the range of the urging point of the lever (four) pressing portion 51 ρ disc convex portion ★ ★ degree H') is the height of the diameter of the vertical center line of the grinding wheel 3, the horizontal tangential minimum point is up 1/3 * Η *2/3, and the urging point p of the pressing portion 51 and the fulcrum c of the convex portion 521 form a slanting angular center, and the urging point p of the pressing portion 51 and the fulcrum c are horizontally tangentially perpendicular to the center line The higher the height H (and/or height H,), the smaller the rotation distance of the user's thumb to drive the grinding wheel 3, the larger the relative position of the force point p of the ink portion 51 and the fulcrum c is. It is known from the fresh principle that if the distance of the anti-arm is constant, and the distance between the arm is smaller, the urging force is greater, and as shown in the figure, the height of the pressing portion 51 - the point of the force point η The higher the (and/or height Η,), the larger the inclination angle 形成 formed by the relative position of the urging point ρ and the fulcrum c, and the smaller the rotation angle υ "or the rotation angle υζ", and then according to the Bishop's theorem It is known that when the fulcrum c is located adjacent to the vertical center line of the grinding wheel 3, and the horizontal distance between the urging point ρ and the vertical center line of the fulcrum c is set to a fixed value, the height of the applied point p is high. The higher the degree, the longer the chord of the triangle, and the more laborious the lever exerts, the greater the force required, due to the increase in the height Η (and/or high sound Η) of the pressing portion 51. The turning distance between the grinding wheel 3 and the thumb is 11 201015030, so it is generally difficult for young children to make a fire by igniting the lighter. Although the user's thumb section and the lighter grinding wheel 3 are smaller, and the lever is small. It is more laborious, but its swirling force is still in the range of the user's ability, so it can improve the safe use of the lighter. The above description is based on the preferred embodiments to explain the invention in detail and not to limit the invention. Anyone who is familiar with such a skilled person can make a slight change and adjustment. It will not lose the essence of the present invention, and will not deviate from the spirit and scope of this invention.
