Description

一种安全打火机 Safety lighter

技术领域 Technical field

本实用新型涉及打火机，尤其涉及一种安全打火机。背景技术 The utility model relates to a lighter, in particular to a safety lighter. Background technique

一般已知的简易型打火机包括包括机身、机头，在机头上设有火嘴、火环、风罩、杠杆压板、弹簧、火石、支架以及打火轮组，打火轮组的中轮、边轮 (包括中轴）固定在一起，同时转动，同时停止，且边轮比中轮稍高，当使用者用一般的力量即可同时转动中轮、边轮（包括中轴），使中轮与火石发生摩擦产生火花，若同时下压压板将释放出燃料，即可达到点燃打火机的目的，但此类简易打火机不能有效地防止儿童玩耍或因意外转动中轮、边轮产生火花导致点燃打火机而发生的各类危险。 A generally known simple lighter includes a fuselage, a nose, a burner, a fire ring, a wind hood, a lever plate, a spring, a flint, a bracket, and a fire wheel set on the handpiece, in the middle of the fire wheel set. The wheel and the side wheel (including the middle shaft) are fixed together, rotate at the same time, stop at the same time, and the side wheel is slightly higher than the middle wheel. When the user uses normal force, the middle wheel and the side wheel (including the center shaft) can be rotated at the same time. The middle wheel and the flint are rubbed to generate a spark. If the press plate is released at the same time, the fuel is released, the purpose of igniting the lighter can be achieved, but such a simple lighter cannot effectively prevent children from playing or sparking due to accidental rotation of the middle wheel and the side wheel. The dangers that result from igniting a lighter.

为安全使用，防止误燃产生的危险，先前的各种,？丈进措施归纳起来有以下几种： For safe use, to prevent the risk of misfire, the previous variety,? There are several ways to summarize the measures:

( 1 )边轮与中轮联为一体，但可与中轴开，且中轴与'中轮、；边轮的间隙较大。另外，边轮的外侧（与拇指的接触面）有小齿。这种改进措施的特点是通过增大转动中轮的力量来增强打火机的安全性。但这种改进措施的缺点是：由于中轴与中轮、边轮的间隙较大，而且边轮的外侧有小齿，所以需要相对较大的力量才能转动中轮，正因为如此，该改进措施的实用性不强，在实践中难以推广。 (1) The side wheel is integrated with the middle wheel, but it can be opened with the middle shaft, and the gap between the middle shaft and the middle wheel; the side wheel is larger. In addition, the outer side of the side wheel (the contact surface with the thumb) has small teeth. This improvement is characterized by an increase in the safety of the lighter by increasing the force of the rotating middle wheel. However, the disadvantages of this improvement measure are: Since the gap between the center shaft and the middle wheel and the side wheel is large, and the outer side of the side wheel has small teeth, relatively large force is required to rotate the middle wheel, which is why the improvement The practicality of the measures is not strong and it is difficult to promote them in practice.

( 2 ) 中轮与中轴、轮的侧面的内 2 / 3联为一伴，中轮的外 1 / 3与前三者不同时转动或停止。中轮的外 1 / 3与内 2 / 3之间有较明显的间隙，两者是可分开的，前者是嵌在后者上的，该改进措施的安全性能较好，但相比较而言，其制造、设计难度较大，导致成本加大，利润降低。 (2) The middle wheel and the center shaft, the inner 2 / 3 side of the wheel are connected as one, and the outer 1 / 3 of the middle wheel rotates or stops at the same time as the first three. There is a clear gap between the outer 1 / 3 and the inner 2 / 3 of the middle wheel. The two are separable. The former is embedded in the latter. The safety of the improvement measures is better, but in comparison It is difficult to manufacture and design, resulting in increased costs and lower profits.

( 3 )增加元器件的方法来增强打火机的安全性能，如利用现有的简易型打确认本火机杠杆压板下方的机身顶端的凹穴，新增加弹片控制件构成一组安全开关，在该控制件的前端下方有一垂直的抵板（注：该抵板上窄下宽、上薄下厚），控制件的板体上设有一贯穿口，利用平时控制件位于下位时的上方板体的贯穿口和杠杆压板下端的突块形成的错位状态，使得杠杆压板不能下压，达到瓦斯无法外溢的安全效果但如果向内推并上抬控制件时，则控制件板体的贯穿口正好向上.套住杠杆压板下方的突块上，使得控制件不能发挥阻挡的作用，此时杠杆压板连同控制件一起降下, 瓦斯得以释放以供点火。而当杠杆压板松开位置上升时，则利用控制件抵板上窄下宽、上薄下厚的形状特点与弹片的互相挤压作用，使控制件维持在下方位置，此时上升后的杠杆压板下端的突块再次与控制件上方板体的贯穿口错置，恢复牡杆压板无法下压的安全状态。该种改进措施的确实增强了打火机的安全性能，但其设计、制造成本的增加也是显而易见的。，！ (3) Ways to increase components to enhance the safety performance of lighters, such as using the existing simple type to confirm this The pocket at the top of the fuselage under the firearm lever platen, the newly added shrapnel control member constitutes a set of safety switches, and there is a vertical abutting plate under the front end of the control member (Note: the plate is narrow, wide, and thin. Thick), the plate of the control member is provided with a through hole, and the displacement state formed by the through hole of the upper plate body and the lower end of the lever pressure plate when the control member is in the lower position is used, so that the lever platen cannot be pressed down, and the gas cannot be obtained. The safety effect of the overflow, but if the control member is pushed in and lifted up, the through hole of the control plate body is just upwards. It is placed on the protrusion below the lever pressure plate, so that the control member cannot play a blocking role, and the lever platen at this time With the control down, the gas is released for ignition. When the lever platen release position is raised, the control member is used to press the plate with a narrow width, a thin upper and a lower thickness, and the elastic member is pressed against each other to maintain the control member in the lower position. The protrusion at the lower end of the pressure plate is again misaligned with the through hole of the upper plate of the control member, and the safety state in which the ram plate is unable to be pressed is restored. This improvement does enhance the safety of the lighter, but the increase in design and manufacturing costs is also evident. , !

不论采用上述。那种方案，都存在着因设计、组装、原材料的增加导致成本提高，销售价格的上升或者利润的明显下降，因而在实践中难以推广的弊端。实用新型内容 Regardless of the above. In that kind of scheme, there are drawbacks that increase in cost due to the increase in design, assembly, and raw materials, an increase in sales price, or a significant drop in profits, and thus it is difficult to promote in practice.

Can effectively prevent accidents or dangers ¹ from happening.

当使用者用一般的力量（即相当于使用现有普通打火机的力量）转动打火轮组时，由于光滑边轮的内、外径大于中轮的外径，因用力不足，拇指不能触及中轮 ^其力量不能带动中轮，光滑边轮与中轮'（包括中轴）不能同时转动或同时停止，所以只能转动光滑边轮，即使拇指顺势压下杠杆压板釋放出了燃料，但由于中轮（包括中轴）并不转动，中轮与火石并没有发生摩擦产生火花，打火机因没有着火源而无法点燃。这样，就可有效地避免儿童玩耍点燃打火机或误将打火轮转动产生火花而引发的危险。 When the user rotates the lighter wheel set with the general strength (that is, the power of using the existing ordinary lighter), since the inner and outer diameters of the smooth side wheel are larger than the outer diameter of the middle wheel, the thumb cannot be touched due to insufficient force. The wheel can't drive the middle wheel, the smooth side wheel and the middle wheel' (including the middle shaft) can't rotate at the same time or stop at the same time, so only the smooth side wheel can be turned, even if the thumb presses down the lever platen to release the fuel, but because The middle wheel (including the middle shaft) does not rotate. The middle wheel and the flint do not have friction to generate sparks. The lighter cannot be ignited because there is no source of ignition. In this way, it is possible to effectively prevent the child from playing the risk of igniting the lighter or accidentally turning the lighter to produce a spark.

当.需要取火时，使用者用较大的力量（即明显大于使用现有普通打火机的力量）转动打火轮组时，指不仅带动光滑边轮，而且因力量足够，还可触及并转动中轮,，使中轮与火石发生摩擦产生火花，此时拇指顺势压下杠杆压板同时释放出了燃料，达到点燃打火机的目的。 When it is necessary to take a fire, when the user turns the lighter wheel group with a large force (that is, significantly greater than the power of using the existing ordinary lighter), the finger not only drives the smooth side wheel, but also has sufficient force to touch and rotate. In the middle wheel, the middle wheel and the flint are rubbed to produce a spark. At this time, the thumb presses down the lever pressure plate and simultaneously releases the fuel to achieve the purpose of igniting the lighter.
