专利汇可以提供Wind-proof cigarette lighter burner专利检索，专利查询，专利分析的服务。并且A miniature burner construction disclosed herein employs a jet pump driven by a fuel jet so as to aspirate air for combustion of the fuel. The jet pump opens into a flame tube in which is positioned a disk-like flameholder having a series of peripheral notches around a central hub. The central hub provides reliable re-circulation and ignition of the incoming air-fuel mixture. Critical ratios relating the cooperating dimensions of the jet pump and burner are disclosed together with the ranges over which satisfactory operation is obtained.，下面是Wind-proof cigarette lighter burner专利的具体信息内容。

权利要求

1. In a cigarette lighter operating on a compressed gas fuel, a burner construction comprising: means defining a fuel jet orifice of diameter D1; means defining a jet pump venturi which is aligned with said fuel orifice, said venturi having an effective diameter D2 and a length L2, the separation between said orifice and the entrance of said venturi being L; a flame tube aligned with said venturi, the inside diameter of said flame tube being D4; and inside said flame tube, a disk-like flameholder providing a central hub and, around said hub, a plurality of peripheral openings, the combined area of said openings being A, said flame-holder being spaced from the outlet of said venturi by a distance L3, said burner being characterized by having a flame tube diameter D4 of about 1/4 inch or less and having proportions such that

2. A burner construction as set forth in claim 1 wherein the length of the flame tube downstream of the flameholder is L4 and L4/D4 is about 1.16.

3. A burner construction as set forth in claim 2 wherein there is a cavity of diameter D3 separating said orifice and the entrance of said venturi and wherein D3/D2 is in the order of 2.4.

4. In a cigarette lighter operating on a compressed gas fuel, a burner construction comprising: means defining a fuel jet orifice of about 0.0019 inch diameter; means defining a jet pump venturi which is aligned with said fuel orifice, said venturi having an effective diameter of about 0.033 inch and a length of about 0.100 inch, the separation between said orifice and the entrance of said venturi being about 0.055 inch; a flame tube aligned with said venturi, the inside diameter of said flame tube being about 0.225 inch; and inside said flame tube a disk-like flameholder providing a central hub and, around said hub, a plurality of peripheral openings, the combined area of said openings being about 0.0025 square inches, said flameholder being spaced from the outlet of said venturi by a distance of about 0.050 inches.

5. A burner construction as set forth in claim 4 wherein the length of the flame tube downstream of the flameholder is about 0.260 inches.

6. A burner construction as set forth in claim 5 wherein there is a cavity of diameter in the order of 0.078 inches separating said orifice and the entrance of said venturi.
