Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a gas burner for a cigarette lighter or a portable lantern that has a proof function.

Conventional technology In recent years, there has been a vigorous movement in the cigarette lighter industry to improve profitability through superiority in the market and higher added value, and the development and commercialization of cigarette lighters with new functions has been rapid. It's starting to change.

Conventional cigarette lighters are intended only for ignition, and recently a cigarette lighter called the Windbruch type, which uses a jet nozzle structure with a fine nozzle hole diameter and uses a burner internal combustion method, has been in the spotlight. Additionally, camping lanterns using gas as fuel have been known for a long time, using light-emitting catalysts for lighting portaple lanterns. Each of these has been commercialized as a single-function product, but in view of the market trends described above, products that link these are attracting attention as a composite product of ignition and lighting.

Problems to be Solved by the Invention In the conventional single-function products as described above, it is necessary to always carry both products as a portable type product, which is inconvenient when used outdoors.

The present invention is intended to solve these problems, and is intended to incorporate a cigarette lighter and a lighting lantern into the same product.

Means for Solving the Problems In order to solve this problem, the present invention provides a light-emitting catalyst on the outer periphery of the burner, further providing a heat-resistant glass on the outer periphery of the light-emitting catalyst with a slight interval, and a heat-resistant glass in the center of the burner. A fine-diameter nozzle hole consisting of a center nozzle hole provided and a plurality of side nozzle holes provided on the outer circumferential side in communication with the passage of the light-emitting catalyst is provided, and a gas flow path downstream of the nozzle hole is provided with a fine-diameter nozzle hole. The burner and heat-resistant glass are provided with air holes.

Effect With this configuration, the gas ejected from the center nozzle hole causes combustion inside the burner as a cigarette lighter, and the gas ejected from the side nozzle holes causes catalytic combustion of the light-emitting catalyst, causing a non-emission phenomenon, and light is emitted from the heat-resistant glass. The same burner can fulfill the two functions of ignition and illumination.

Embodiment FIGS. 1, 2 and 3 show a gas burner according to an embodiment of the present invention. The configuration will be explained according to the numbers along with the drawings. 1, 2, and 3, 1 is a burner, which has a center nozzle hole 1a with a minute diameter of about 30 to 80 μm in the center, and a plurality of identical (3
A side nozzle hole 1b having a fine diameter of about 0 to 80 μm is provided, and an air hole IC for sucking primary air is provided in the burner 1 downstream of the gas flow path of each nozzle hole 1a, lb. A diffuser provided in the burner 1 has the function of mixing and diffusing the gas from the center nozzle hole 1a and the primary air sucked in from the air hole 1c to create an optimal mixture for ignition.

3 is a wire mesh that makes it easy to check the combustion state from the outside due to the combustion inside the burner 1 (it becomes red hot, and has a windshield effect against slight winds). It is provided in the burner 1 at a position downstream of the flow path. 4 is a light-emitting catalyst, and is installed on the upper outer periphery of the burner 1 at a position downstream of the flow path of the side nozzle hole 1b. 5 is heat-resistant glass, and the light-emitting catalyst 4 An air hole 5a for sucking primary air is located downstream of the flow path of the side nozzle hole 1b in conjunction with the air hole 1c of the burner 1 at the same position as the air hole 1c of the burner 1. There is.

The combustion process will be explained below. First, gas ejected from a gas tank (not shown) is ejected from the center nozzle hole 1a and side nozzle hole 1b with increased gas pressure, and at the same time from the air holes 1c and 5a of the burner 1 and heat-resistant glass 5 immediately downstream. Primary air is sucked in due to the negative gas pressure, resulting in the optimum mixture for combustion. Next, the air-fuel mixture (to be ignited (the ignition means is not directly related to the present invention and will not be illustrated or described)) is heated inside the burner 1 and partially outside the wire mesh 3 as a normal internal heat cigarette lighter in the central burner section. Combustion is carried out, while the gas ejected from the side nozzle hole 1b reacts with the light-emitting catalyst 4 and catalytically burns.
The light emitted during combustion is transmitted through the heat-resistant glass 5 and produces an illumination effect.

Effects of the Invention As described above, according to the present invention, a light-emitting catalyst is provided on the outer periphery of the burner, heat-resistant glass is further provided on the outer periphery of the light-emitting catalyst with a slight interval, and the burner has a center nozzle provided in the center. A micro-diameter nozzle hole consisting of a hole and a plurality of side nozzle holes provided on the outer circumferential side in communication with the passage of the light-emitting catalyst is formed, and a burner and a heat-resistant glass are provided downstream of the gas flow path of this nozzle hole. The structure with air holes allows the same burner to have two functions: ignition and lighting, so it is used as a cigarette lighter with a new shiny image, and as a simple light at night. It is also possible to use Furthermore, if the fuel tank part is used as a grip and it is shaped like a conventional hunt lighter for igniting gas appliances, it can also be used as a porta-pull lighting device, and has extremely high practical value.
