Description

Technical field

[0001] The practical new skid type safety lighter is a kind of lighter, especially concerning a safety lighter that can prevent the children from playing fire.

Background technology

[0002] Common steel wheel lighter is composed of shell and external nose. The external nose is installed on the shell. The external nose is equipped with the following parts, including spring, flint, lever and striking fire wheel, etc. The striking fire wheel is composed of fixed wheel and middle wheel. By stirring the fixed wheel with fingers, the middle wheel can be driven and abraded with the flint so as to achieve the purpose of firing. However, such common steel wheel lighter ignores safety, especial the safety protection for children. Content of the practical new skid type safety lighter
The purpose of the practical new skid type safety lighter is to avoid the shortcoming of existing technology and provide a simple, convenient and low-cost lighter with children-resistance safety protection device.
The purpose of the practical new skid type safety lighter is achieved by the following measures: the lighter is composed of wheel, windshield, air valve assembly, spring, flint, lever and striking fire wheel. The striking fire wheel is composed of fixed wheel, middle wheel and slide wheel. Both ends of the fixed wheel are installed on the shell with shaft. The middle wheel is installed and encased to the fixed wheel. Slide wheel is installed and encased to the fixed wheel. The slide wheel is close to the fixed wheel. The diameter of slide wheel is larger than that of the fixed wheel. There is a difference in height between the slide wheel and the fixed wheel. By stirring the fixed wheel with fingers, the middle wheel is driven and abraded with the flint. While stirring the fixed wheel, the adult can stir both the fixed wheel and slide wheel with a thumb simultaneously; while the thumb of children is relatively small, they can only stir the slide wheel and let it run idle, instead of driving the middle wheel simultaneously with the presence of the difference in height between the slide wheel and fixed wheel. The middle wheel cannot be driven or abraded with the flint, so the purpose of safety is achieved.
For the practical new skid type safety lighter, a slide wheel is installed on both sides of the fixed wheel respectively, between the middle wheel and the fixed wheel.
For the practical new skid type safety lighter, a slide wheel is installed on both sides of the fixed wheel respectively, between the middle wheel and the fixed wheel.
The practical new skid type safety lighter has simple structure, convenient installation and high safety. By utilizing the feature that the thumb of adult is larger than that of the children skillfully, it can prevent the children below seven from striking the lighter by accident effectively so as to play a safety role of preventing the children from playing fire.

Detailed implementation method:

[0003] Further description is given below for the Practical new Skid Type Safety Lighter in combination with the attached figures. As shown in attached figure 1, the practical new lighter is composed of shell 10, windshield 1, air valve assembly (not shown), spring 8, flint 7, lever 3 and striking fire wheel 2. The striking fire wheel 2 is composed of fixed wheel 4, middle wheel 6 and slide wheel 5. Both ends of the fixed wheel 4 are rotatable installed on the shell 10 with shaft 9. The middle wheel 6 is installed on the fixed wheel 4. The slide wheel 5 is installed and encased to the fixed wheel 4. The slide wheel 5 is close to the fixed wheel 4. The diameter of slide wheel 5 is larger than that of the fixed wheel 4. There is a difference in height between the slide wheel 5 and the fixed wheel 4.

[0004] As shown in attached figure 2, the practical new lighter is composed of shell 10, windshield, air valve assembly (not shown), spring 8, flint 7, lever 3 and striking fire wheel 2. The striking fire wheel 2 is composed of fixed wheel 4, middle wheel 6 and slide wheel 5. Both ends of the fixed wheel 4 are rotatable installed on the shell 10 with shaft 9. The middle wheel 6 is installed on the fixed wheel 4. The slide wheel 5 is installed on one side of the fixed wheel 4 and is encased to the fixed wheel 4. The diameter of slide wheel 5 is larger than that of the fixed wheel 4. There is a difference in height between the slide wheel 5 and the fixed wheel 4.

[0005] As shown in attached figure 3, the striking fire wheel 2 of the practical new lighter is composed of fixed wheel 4, middle wheel 6 and slide wheel 5. The slide wheel 5 is installed on the fixed wheel 4. The diameter of the slide wheel 5 is larger than that of the fixed wheel 4. There is a difference in height between the slide wheel 5 and fixed wheel 4. By stirring the fixed wheel 4 and slide wheel 5 simultaneously with a thumb 14, the adult can stir the fixed wheel 4 to drive the middle wheel 6 and cause the abrasion between the middle wheel 6 and the flint 7. While the thumb of children is relatively small, they can only stir the slide wheel 5 and let it run idle, instead of driving the middle wheel 6 simultaneously with the presence of the difference in height between the slide wheel 5 and fixed wheel 4. The middle wheel 6 cannot be driven or abraded with the flint 7, so the purpose of safety is achieved.

[0006] However, it is a feature of the invention that the slide wheel 5 is fixed neither on the fixed wheel 4 nor on the middle wheel 6. This allows a rotation of the slide wheel 5 when activate by a thumb 14 with lost motion. For achieving the idle function the slide wheel 5 as shown in Fig. 2 and Fig. 3 is provided with a centre bore 11. By this centre bore 11 the slide wheel 5 is slackly attached on a shoulder 12 of the inner shaft 13 of the fixed wheel 4. Otherwise it is also possible to attach the slide wheel 5 directly on the inner shaft 13 or on the shaft 9. For attaching slackly the diameter of the centre bore 11 is larger than the diameter of the shoulder 12 or larger than the diameter of the shaft 9 or 13 since directly attached thereon.

[0007] It is a second important feature of the invention that the outer diameter of the slide wheel 5 is larger than the diameters of the adjacent wheels, i.e. in the example of Figs. 1 to 3 larger than the diameters of the fixed wheel 4. Thereby a thumb of a child could only engage the slide wheel 5 but not the fixed wheel 4 simultaneously and the slide wheel 5 is in idle function.

[0008] It is reasonable to arrange one or more slide wheels 5 in the neighborhood of the fixed wheel 4, i.e. between the shell 10 and the fixed wheel 4 or between the fixed wheel 4 and the middle wheel 6 as shown in the Figs. 1 to 3.

[0009] To increase the safety, the circumferential surface of the slide wheel 5 is knurled and the circumferential surface of the adjacent wheels, e.g. the fixed wheel 4 is unruffled. A torsion of the fixed wheel 4 is complicated whereas the useless torsion of the slide wheel 5 is facilitated.
