Description

Technical Field

[0001] The utility model belongs to the field of cigarette lighters, in particular to a composite flame burner which uses liquid-stored combustible gas (such as butane gas) as fuel to generate a composite flame of a direct flame and an open flame, and further relates to a lighter containing the composite flame burner. Background Art

[0002] The operating principle of a lighter mainly depends on the energy conversion efficiency of the ignition mechanism, that is, how to effectively convert mechanical energy or electrical energy into thermal energy to ignite the fuel gas. For example, a piezoelectric ceramic lighter generates a high-voltage electric spark by applying physical pressure to the piezoelectric material. This spark instantly ignites the fuel gas and produces a continuous flame. According to the type of flame generated, lighters are divided into two types: open flame and direct fire. Each type has its own characteristics and is suitable for different usage scenarios.

[0003] Open flame lighter

[0004] Flame stability: The flame stability of open flame lighters is better and is not easily blown out by wind. This is because the flame outlet of open flame lighters is usually designed to be smaller and the flame temperature is higher, so that it can remain stable even under normal wind force.

[0005] Durability: The fuel consumption of open flame lighters is slow, so their durability is relatively good. This type of lighter will not generate excessive gas pressure when in use, thus reducing the wear of mechanical parts and extending the service life.

[0006] Applicable scenarios: Open flame lighters are particularly suitable for outdoor activities such as camping and barbecue due to their stable flame and durability. They are also suitable for daily household use, such as lighting candles and tobacco.

[0007] Straight fire lighter

[0008] Flame size: Straight-fire lighters usually have larger flames, which are suitable for quickly lighting items that require a large flame. This type of lighter is more convenient to use indoors or in a calm environment, and can quickly light tobacco, candles and other items.

[0009] Fuel consumption: Direct-fire lighters consume fuel quickly because they use gas compression and direct-fire. Although this can produce a larger flame, it also means rapid loss of gas.

[0010] Applicable scenarios: Direct-fire lighters have larger flames and are more suitable for use indoors or in quiet environments, such as homes and offices.

[0011] However, there is a need in the market for a lighter that is windproof, has the characteristics of a candlelight flame, can be ignited quickly and has a large-diameter flame body. Utility Model Content

[0012] The purpose of the utility model is to provide a composite flame burner, which has both windproof and candle flame, and comprises:

[0013] The inner ignition seat comprises an inner ignition seat body, which in turn comprises a straight-into-fire port and a mounting cavity, a straight-into-fire burner is fixed in the mounting cavity, a first gas supply pipe supplies fuel gas to the straight-into-fire burner and can form a straight-into-fire flame at the straight-into-fire port;

[0014] The external ignition seat comprises an external ignition seat body, the external ignition seat body comprises a gas supply pipe hole, and a second gas supply pipe is installed at the gas supply pipe hole and supplies fuel gas;

[0015] An ignition mechanism capable of igniting fuel gas at a direct-fire burner to form a direct-fire flame;

[0016] Among them, the outer ignition seat is arranged outside the inner ignition seat, and an open flame air supply port B is formed between the outer ignition seat and the inner ignition seat. The direct fire from the direct fire port can ignite the fuel gas in the open flame air supply port B and form an open flame and a composite flame.

[0017] Preferably, it also includes: there are multiple open flame air supply ports B, which are distributed circumferentially along the straight-fire port, and the open flames formed by the open flame air supply ports B cover the outer side of the straight-fire flame formed at the straight-fire port.

[0018] Preferably, the outer ignition seat further includes a fixed cavity, an annular cavity, and an inner wall of the outer ignition seat in sequence.

[0019] The fixing cavity contacts the outer wall of the inner ignition seat and fixes the inner ignition seat inside the outer ignition seat;

[0020] An annular gas supply groove A is formed between the annular cavity and the outer wall of the inner ignition seat, and the annular gas supply groove A is connected to the second gas supply pipe;

[0021] An open flame air supply port B is formed between the inner wall of the outer ignition seat and the outer wall of the inner ignition seat.

[0022] Preferably, it also includes: an outer wall of the inner ignition seat is provided with an air supply groove, and the air supply groove and the inner wall of the outer ignition seat together form an open flame air supply port B.

[0023] Preferably, it also includes: the open flame gas supply port B supplies fuel gas obliquely toward the straight-impact fire port.

[0024] Preferably, it also includes: the straight-into-fire port has a conical and enlarged air outlet.

[0025] The utility model also provides a lighter, which comprises a gas storage box and the aforementioned composite flame burner. The gas storage box supplies fuel gas to the composite flame burner through a first gas supply pipe and a second gas supply pipe.

[0026] Beneficial effects:

[0027] The composite flame burner has both the windproof property of a straight fire and the candlelight property of an open flame. When in use, a strong straight blue flame is first generated from the direct fire burner, and then the combustion gas from the open flame air supply port on the outer circle is ignited to form an evenly distributed open flame. Thus, a composite flame is generated with a straight blue flame inside and an open candlelight flame outside. The volume of the composite flame is significantly larger than that of a traditional straight flame, and it has the advantages of both fast ignition and even combustion, which is both fast and convenient.

DETAILED DESCRIPTION

[0034] The above and other technical features and functions of the present invention are described in detail below with reference to the attached Figures 1 to 5 The embodiments are described in detail.

[0035] the term:

[0036] Straight-fire burner: Straight-fire burner is the core component of straight-fire lighter in the prior art, which is responsible for mixing gas and air and igniting. Gas enters the straight-fire burner from the gas tank through a fine nozzle, where it is fully mixed with air and ignited by the spark generated by the ignition device. This process generates one or more strong straight-fire flames. The burner head is usually located at the top of the straight-fire burner and is the final port for flame formation and discharge. Its design directly affects the shape and size of the flame. The burner head of the straight-fire lighter can produce a rod-shaped, concentrated flame, which is more suitable for rapid ignition.

[0037] Ignition device: The ignition device ensures that the gas from the nozzle to the combustion head can be reliably ignited. At the moment when the user operates the ignition device, the ignition device ensures that the spark and the gas are in synchronous contact, achieving high-efficiency and high-reliability ignition. This process relies on the precise coordination of the ignition device and the gas system, ensuring the immediacy and safety of ignition.

[0038] Shell and gas tank assembly: The shell protects the internal mechanism and gas tank assembly of the lighter, while providing a user-friendly operating interface. The gas tank stores volatile liquid fuels such as butane or propane, providing a continuous gas supply for the lighter.

[0039] All functionality described in conjunction with one embodiment is intended to be applicable to the additional embodiments described below, unless expressly stated otherwise or the feature or functionality is incompatible with the additional embodiments. For example, when a given feature or functionality is expressly described in conjunction with one embodiment but not expressly mentioned in conjunction with an alternate embodiment, it is understood that the inventors intend that the feature or functionality may be deployed, utilized, or implemented in conjunction with the alternate embodiment, unless the feature or functionality is incompatible with the alternate embodiment.

[0040] exist Figure 1 An igniter for forming a composite flame in a lighter is shown, which can convert the combustion gas into a composite flame. The combustion gas can be a combustible gas in the prior art, such as liquefied petroleum gas, which is one of the common fuel gases in lighters. It is a gas produced by refineries when refining crude oil. These gases can be liquefied under pressurized and cooled conditions, which is convenient for storage and transportation; butane is another commonly used lighter gas, which is a colorless and odorless hydrocarbon with the characteristic of easy liquefaction, which makes it particularly suitable for use as a fuel for portable lighters. Propane is also a fuel that may be used in lighters. Similar to butane, it is also a colorless and odorless hydrocarbon, but its melting point is lower and it is more suitable for use in low temperature environments.

[0041] In this embodiment, the composite flame burner comprises: an inner ignition seat 20, which comprises an inner ignition seat body 21, the inner ignition seat body 21 comprises a straight-into-fire port 23 and a mounting cavity 22 in sequence, a straight-into-fire burner 30 is fixed in the mounting cavity 22, a first gas supply pipe 31 supplies fuel gas to the straight-into-fire burner 30 and can form a straight-into-fire flame at the straight-into-fire port 23;

[0042] The external ignition seat 10 includes an external ignition seat body 11, the external ignition seat body 11 includes a gas supply pipe hole 15, and a second gas supply pipe 16 is installed at the gas supply pipe hole 15 and supplies fuel gas;

[0043] like Figure 1 As shown, the outer ignition seat 10 is sleeved on the outside of the inner ignition seat 20, and an open flame air supply port B is formed between the outer ignition seat 10 and the inner ignition seat 20. The direct fire of the direct fire port 23 can ignite the fuel gas of the open flame air supply port B and form an open flame. That is, when in use, the ignition mechanism is first triggered, and the ignition mechanism controls the ignition device to ignite the fuel gas at the direct fire burner 30 to form a direct flame. Under the action of the direct flame, the fuel gas of the open flame air supply port B in the outer circle is ignited, forming a composite flame with a direct flame inside and an open flame outside.

[0044] In the composite flame, the internal straight fire provides a stable and continuous flame, which is suitable for occasions that require long-term stable heating. This type of flame can ensure stable operation even in harsh environments such as strong winds, and reduces the situation of being extinguished by wind or air pressure changes. The external open flame provides a strong and immediate heat source, which is suitable for quickly igniting tobacco or candles. Its existence makes ignition faster and greatly improves the efficiency of use. This embodiment provides a multifunctional, safe, reliable and efficient ignition solution. This design not only adapts to various environmental conditions, but also meets strict practical needs. It is an ideal choice for outdoor explorers, smokers, and those who need a fast and reliable fire source in daily life.

[0045] In order to provide a more stable composite flame, there can be multiple open flame air supply ports B, which are distributed circumferentially along the straight burner port 23, and especially evenly distributed circumferentially along the straight burner port 23. At this time, the open flame formed by the fire supply port B evenly covers the outside of the straight burner port 23 to form a composite flame.

[0046] In some embodiments, Figure 2 and Figure 3As shown, the outer ignition seat 10 is annular as a whole, and is used to be sleeved on the outer side of the inner ignition seat 20. The inner circle of the outer ignition seat 10 also includes a fixed cavity 12, an annular cavity 13, and an inner wall 14 of the outer ignition seat in sequence, and is adapted to the shape of the outer wall of the inner ignition seat 20. Among them, the fixed cavity 12 contacts the outer wall of the inner ignition seat 20 and fixes the inner ignition seat 20 inside the outer ignition seat 10; an annular gas supply groove A is formed between the annular cavity 13 and the outer wall of the inner ignition seat 20, and the annular gas supply groove A is connected to the second gas supply pipe 16; an open flame gas supply port B is formed between the inner wall 14 of the outer ignition seat and the outer wall of the inner ignition seat 20. After assembly, the outer ignition seat 10 and the inner ignition seat 20 are assembled into a composite flame burner.

[0047] In some embodiments, Figure 4 and Figure 5 As shown, the outer wall of the inner ignition seat 20 is provided with an air supply groove 24, which is formed at the upper end of the outer wall of the inner ignition seat 20 and is recessed inward from the flat outer wall surface. The air supply groove 24 and the inner wall 14 of the outer ignition seat together form an open flame air supply port B. Forming the air supply groove 24 in this way can greatly reduce the processing cost of the open flame air supply port B.

[0048] In some embodiments, the shape and direction of the gas supply port are the key design elements to be considered in this embodiment. The gas supply port is responsible for ejecting the fuel gas in a certain shape and speed. Not only the gas supply direction and gas supply volume should be considered, but also the full mixing with the air should be considered. The design of the gas supply port directly affects the size, shape and stability of the flame. In this embodiment, the open flame gas supply port B tilts the fuel gas toward the straight-fire port 23, so that it can cooperate with the conical flame formed by the straight-fire burner to form a substantially conical composite flame.

[0049] In some embodiments, in order to obtain a straight flame with a larger diameter, the straight flame port 23 has a tapered, enlarged air outlet, so that the size of the air outlet is expanded as much as possible, while also shortening the radial distance between the straight flame port 23 and the open flame air supply port.

[0050] In some embodiments, a lighter is provided, which includes a gas storage box and the aforementioned composite flame burner. The gas storage box supplies fuel gas to the composite flame burner through a first gas supply pipe 31 and a second gas supply pipe 16, and forms a composite flame with a straight flame inside and an open flame outside.

As noted above, some embodiments within the scope of the present disclosure and claims may not provide the specific advantages set forth above. That said, the most preferred embodiments provide many, most, or all of the aforementioned advantages relative to conventional heat-not-burn and e-cigarette devices.

[0052] Although certain embodiments have been described, these embodiments are given by way of example only and are not intended to limit the scope of the present disclosure. Indeed, the novel methods, devices, and systems described herein may be embodied in a variety of other forms; furthermore, various omissions, substitutions, and changes in the form of the methods, devices, and systems described herein may be made without departing from the spirit of the present disclosure.
