CN1415893A - Lighter with security structural metal case - Google Patents

Abstract

This invention is newly designed to the internal structure of combustion part in which when a safety state is needed, the metal case lighter only needs to turn an adjuster round to drive a conical unit with an inlet on it to contrarotate over 90 deg. to the state of picture and the inlet on sidewall of the conic and outlet of the combustion chamber will not connect again which enables the metal case lighter to control fuel with a witch, suitable for different moulding new safety structure.

Description

Metal shell lighter with safeguard construction

The present invention relates to a kind of metal shell lighter with safeguard construction.

Existing metal shell lighter, fuel all are from nozzle carrier ⁽⁴⁾(Fig. 3) Xia Mian cylinder ⁽⁹⁾The air admission hole of lower end (not being sidewall) (Fig. 3 10) is entered.Therefore, when lighter does not use, fuel compartment ⁽⁵⁾In fuel to nozzle ⁽¹⁾Air admission hole ⁽¹⁰⁾Remain unlimited.Because fuel compartment ⁽⁵⁾Venthole ⁽¹²⁾Open wide,, in children's hand, just be easy to generate problem if lighter does not add safety device.

The metal shell lighter is because different modeling, changes very soon, and according to existing structure, it is very difficult that existing safety device is installed.Have only from structure and deal with problems.

The present invention sets about from the internal structure of lighter, to fuel compartment ⁽⁵⁾Venthole (Fig. 3 12) and nozzle carrier ⁽⁴⁾Air admission hole (Fig. 3 10), redesign.Be not original straight hole down, directly and fuel compartment ⁽⁵⁾Venthole ⁽¹²⁾Join.But be designed to present structure, see Fig. 1, Fig. 2 they (10), (11), (12).Fuel compartment ⁽⁵⁾Venthole ⁽¹²⁾, pass through fuel compartment ⁽⁵⁾Outer wall ⁽⁶⁾On passage ⁽¹¹⁾, with nozzle carrier ⁽⁴⁾Following cone ⁽⁹⁾Air admission hole on the sidewall ⁽¹⁰⁾Link (seeing Fig. 2 they (10), (11), (12)).

Former nozzle carrier of while ⁽⁴⁾Be drilled with air admission hole below ⁽¹⁰⁾Parts ⁽⁹⁾, be designed to cone ⁽⁹⁾, but and nozzle carrier ⁽⁴⁾Do not combine as a whole (see Fig. 1, see Fig. 5 for details, Fig. 6), a sealing ring is housed between them, and, cone ⁽⁹⁾With fuel compartment ⁽⁵⁾Outer wall ⁽⁶⁾The conical bore of last design ⁽⁸⁾(seeing Fig. 4 for details) closely cooperates, and is combined into sealing surface ^(8,9)(see Fig. 2, work as cone ⁽⁹⁾At conical bore ⁽⁸⁾In when rotating, tight as can not leak gas).

Add and pass through adjuster ⁽²⁾(see Fig. 1, Fig. 7), adjuster ⁽²⁾Be one and have handle ^(2-1)With the cylinder that has sealing ring ^(2-2), by screw thread and cone ⁽⁹⁾Connect.Pass through adjuster ⁽²⁾Handle ^(2-1)Rotation regulator ⁽²⁾Drive cone ⁽⁹⁾, drive cone again ⁽⁹⁾On air admission hole ⁽¹⁰⁾More than the half-twist, the closed position to Fig. 1 makes cone ⁽⁹⁾Air admission hole on the sidewall ⁽¹⁰⁾With fuel compartment ⁽⁵⁾Venthole ⁽¹²⁾No longer be communicated with (seeing Fig. 1 they (10), (11), (12)).

Simultaneously, because cone ⁽⁹⁾With conical bore ⁽⁸⁾The sealing function of the conical surface, make fuel compartment ⁽⁵⁾The gas outlet ⁽¹²⁾Passage ⁽¹¹⁾With cone ⁽⁹⁾Air admission hole on the sidewall ⁽¹⁰⁾All sealed face is sealed simultaneously, and fuel can't be from the hole ⁽¹²⁾Release, also can't be from air admission hole ⁽¹⁰⁾Enter.Guaranteed the safety of the combustion gas when lighter is in Fig. 1 closed condition.

Under this state, even taking lighter, children operate, because fuel is sealed, fuel can't enter nozzle ⁽¹⁾So, can not produce flame.

When needs use lighter, pass through adjuster ⁽²⁾Handle ^(2-1)Rotation regulator ⁽²⁾Cylinder ^(2-2)Drive cone ⁽⁹⁾Drive cone again ⁽⁹⁾On air admission hole ⁽¹⁰⁾Reverse rotation is more than 90 °, and the state to Fig. 2 makes fuel compartment ⁽⁵⁾Venthole ⁽¹²⁾, pass through passage ⁽¹¹⁾With cone ⁽⁹⁾Air admission hole on the sidewall ⁽¹⁰⁾Communicate.Gas will enter nozzle swimmingly ⁽¹⁾,, can produce flame as long as start ignition device.Operation is very easily.

Safeguard construction illustrates:

See Fig. 1, Fig. 2

1. nozzle ⁽¹⁾

2. adjuster ⁽²⁾(have handle ^(2-1)And sealing ring ⁽⁷⁾Cylinder ^(2-2)) (seeing Fig. 1, Fig. 7 for details)

4. nozzle carrier ⁽⁴⁾, (seeing Fig. 6 for details)

5. fuel compartment ⁽⁵⁾, (seeing Fig. 4 for details)

6. fuel compartment ⁽⁵⁾Outer wall ⁽⁶⁾, (seeing Fig. 4 for details)

7. sealing ring ⁽⁷⁾

8. fuel compartment ⁽⁵⁾Outer wall ⁽⁶⁾On conical bore ⁽⁸⁾, (seeing Fig. 4 for details)

9. nozzle carrier ⁽⁴⁾Following cone ⁽⁹⁾, (seeing Fig. 5 for details)

10. cone ⁽⁹⁾Nozzle on the sidewall ⁽¹⁾Air admission hole ⁽¹⁰⁾, (seeing Fig. 5 for details)

11. fuel compartment ⁽⁵⁾Outer wall ⁽⁶⁾Last fuel advances the nozzle air admission hole ⁽¹⁰⁾Passage ⁽¹¹⁾, (seeing Fig. 4 for details)

12. fuel compartment ⁽⁵⁾Venthole ⁽¹²⁾(fuel outlet), (seeing Fig. 4 for details)

Claims (1)

1. the feature of the safeguard construction of metal shell lighter of the present invention is: see specification Fig. 1, and shown in Figure 2: by cone ⁽⁹⁾And by cone ⁽⁹⁾Air admission hole on the sidewall ⁽¹⁰⁾(seeing Fig. 5 for details) is by fuel compartment ⁽⁵⁾Outer wall ⁽⁶⁾On conical bore ⁽⁸⁾(seeing Fig. 4 for details) is by cone ⁽⁹⁾With by fuel compartment ⁽⁵⁾Outer wall ⁽⁶⁾On conical bore ⁽⁸⁾The sealing surface of being formed ^(8,9)(seeing Fig. 2 they (8,9) for details) is by cone ⁽⁹⁾Air admission hole on the sidewall ⁽¹⁰⁾With fuel compartment ⁽⁵⁾Outer wall ⁽⁶⁾On passage ⁽¹¹⁾And fuel compartment ⁽⁵⁾Venthole ⁽¹²⁾The fuel channel of forming nozzle, (seeing Fig. 2 they (10), (11), (12) for details) adds by the band handle ^(2-1), have a cylinder of sealing ring again ^(2-2)Adjuster ⁽²⁾, adjuster ⁽²⁾On screw thread and cone are arranged ⁽⁹⁾Connect the regulation device of composition (Push And Release of control fuel), nozzle carrier ⁽⁴⁾With cone ⁽⁹⁾Separate, middle structure of isolating with sealing ring has guaranteed that the metal shell lighter can correctly control the Push And Release of fuel on the structure.
