Description

Lighter gas supply components

Technical Field

The utility model belongs to the field of lighters, in particular to a gas supply component for a lighter.

Background Art

As an ignition device, lighters are easily blown out by strong winds during daily use. Therefore, manufacturers have designed lighters with windproof properties. The gas is regulated and enters the gasification chamber. After being fully mixed with the air, it is ignited by the piezoelectric igniter. The gas is ejected from the ignition chamber at high pressure, thus forming a flame.

The existing lighter combustion head is usually plugged into the air outlet needle as a whole, and the rubber sealing sleeve in the air intake assembly of the combustion head cooperates with the upper end of the air outlet needle. Since the rubber sealing sleeve is small in size, a small amount will be larger in size during batch production, resulting in the rubber sealing ring being unable to be well fixed to the air outlet needle; in addition, if the burning time is long, the rubber sealing ring will expand due to heat, which will also cause the rubber sealing ring to be unable to fix the air outlet needle, affecting product quality; in addition, if one of the components of the lighter combustion head is damaged, it usually can only be replaced as a whole, and the maintenance cost is high.

Summary of the invention

In order to overcome the shortcomings of existing lighters such as poor product quality stability and high maintenance cost, the utility model provides a lighter gas supply assembly which improves product quality and reduces maintenance cost.

The technical solution adopted by the utility model to solve its technical problems is:

A lighter air supply assembly comprises a sleeve, an air inlet head and an air outlet needle, the air inlet head comprises an air inlet sleeve and an air inlet assembly, the air inlet assembly is located in the air inlet sleeve, the air outlet needle is connected to the air inlet assembly, an air inlet port is formed at the upper portion of the sleeve, the air inlet sleeve can be movably mounted in the lower portion of the inner cavity of the sleeve, the air supply assembly also comprises a fixed sleeve for positioning the sleeve, the lower portion of the sleeve is fixed in the fixed sleeve, and the fixed sleeve is fixedly connected to a ignition adjustment ring of the lighter.

Furthermore, the lower portion of the sleeve is inserted into the fixing sleeve.

Alternatively, the lower portion of the sleeve is clamped in the fixing sleeve.

Preferably, the lower part of the sleeve is provided with a convex part, the inner cavity of the fixing sleeve is provided with a groove, and the convex part is engaged with the groove. Of course, other engaging modes are also possible.

Furthermore, the fixing sleeve is integrated with the ignition adjustment ring of the lighter.

Furthermore, the air supply component also includes an air blocking member for preventing excess air supply, wherein the air blocking member is a normally closed air valve, and the air blocking member is located in the inner cavity of the sleeve. When the air intake sleeve moves upward to push open the air blocking member, it is in an open ventilation state, and when the air intake sleeve moves downward and the air blocking member is reset, it is in a closed state.

Furthermore, the gas blocking member is installed in a mounting groove in the middle of the inner cavity of the sleeve, which is a preferred mounting solution for the gas blocking member.

Preferably, a protrusion is provided on the top of the air inlet sleeve.

The air blocking member comprises an annular body and an air blocking member tip, wherein the air blocking member tip is located in the middle of the annular body and matches with the convex tip of the air inlet sleeve.

More preferably, a straight hole or a cross hole is opened in the center or eccentric position of the gas blocking member.

The lower part of the fire adjusting ring is connected with the fixing ring. This split arrangement is conducive to batch assembly. Of course, the fire adjusting ring and the fixing ring can also be integrated.

In the utility model, the sleeve is positioned on the fixed sleeve, and the fixed sleeve is fixed to the ignition ring of the lighter, so that the entire upper combustion head part is effectively fixed, and even if the fit between the air outlet needle and the rubber sealing ring of the air inlet component is loose, it will not affect the overall connection stability; in addition, since the sleeve and the air inlet head are not fixedly connected, if one of the components is damaged, it only needs to be replaced.

Since the gas blocking member is provided, even if there is residual gas, the residual gas can be exhausted downwards and no longer supply gas upwards; or even if the gas blocking member is not completely sealed and some gas is supplied upwards, the direction is changed by the blocking member, and the high-pressure gas is reduced to low-pressure compressed gas, which loses the power to supply gas upwards and is insufficient for upper combustion.

The beneficial effects of the utility model are mainly manifested in: 1. Improving product quality and reducing maintenance costs; 2. Since the gas blocking part is provided, the safety performance is effectively improved and the user experience is improved.

Furthermore, the fixing sleeve 6 - 2 is integrated with the lighter ignition ring 6 .

The air supply assembly also includes an air blocking member 7 for preventing excess air supply. The air blocking member 7 is a normally closed air valve. The air blocking member 7 is located in the inner cavity of the sleeve 5. When the air intake sleeve 14 moves upward to push open the air blocking member 7, it is in an open ventilation state. When the air intake sleeve 14 moves downward, the air blocking member 7 is reset and it is in a closed state.

Furthermore, the gas blocking member 7 is installed in the installation groove in the middle of the inner cavity of the sleeve 5. This is a preferred installation scheme of the gas blocking member 7.

A convex tip 14 - 1 is provided on the top of the air inlet sleeve 14. This solution is more conducive to opening the air blocking member 7.

The air blocking member 7 comprises an annular body and an air blocking member tip, wherein the air blocking member tip is located in the middle of the annular body and cooperates with the convex tip 14 - 1 of the air inlet sleeve.

Furthermore, the gas barrier 7 is an elastic material gas barrier. The elastic material is sealing rubber. Of course, it can also be other materials, such as elastic metal sheets.

Furthermore, a straight hole is provided in the middle of the air blocking member 7. Preferably, the air blocking member 7 has two straight holes, and the two straight holes are arranged crosswise. For example, it can be a cross hole, or a cross hole. More preferably, a straight hole or a cross hole is provided in the center or eccentricity of the air blocking member 7.
