Description

Technical Field

[0001] This utility model belongs to the field of ignition device technology, specifically a flame adjusting plate and a lighter. Background Technology

[0002] In ignition devices such as lighters, ignition guns, and small gas welding torches, a flame adjustment device is provided at the gas outlet to facilitate the adjustment of the size of the ignition flame. This device includes a guide tube that can extend into the liquid combustible gas. The upper end of the guide tube is connected to the flame adjustment plate by an aluminum nail. A rotating screw is also provided at the upper end of the flame adjustment plate, and the flame adjustment plate is sandwiched between the aluminum nail and the rotating screw.

[0003] Flame adjusters are typically made of foam. During ignition, turning a rotating screw adjusts the distance between the screw and the aluminum pin, allowing for the compression and release of the foam, thereby controlling the gas flow at the ignition device's outlet and thus adjusting the size of the ignition flame. Chinese utility model patent CN211854087U discloses a flame adjuster including a foam layer and a breathable reinforcing and stabilizing layer superimposed on the foam layer. By adding reinforcing and stabilizing layers made of polyurethane fabric to the upper and lower ends of the foam layer, excessive compression of the foam during mechanical assembly and subsequent use can be prevented.

[0004] In the aforementioned scheme, the fabrication of a multi-layered flame modulator requires the use of a pressing device to bond the foam and polyurethane fabric into a single structure. This process is cumbersome and incurs significant production costs. Furthermore, due to the uneven pore distribution within the foam and polyurethane fabric, combustible gas cannot smoothly pass through the pore structures of the different materials during its ascent. The more layers of material there are, the greater the obstruction to the combustible gas. When the ignition switch is pressed for the first time, the combustible gas cannot be fully discharged from the drain tube, resulting in unstable flame combustion and potentially causing flame spikes. Multiple presses of the ignition switch are required to achieve stable flame combustion. In addition, the polyurethane fabric has poor heat resistance and is prone to chemical reactions at high temperatures. After prolonged use, the polyurethane fabric may soften or decompose, losing its reinforcing and stabilizing effect on the foam, leading to foam damage and impairing its flame modulating function. Utility Model Content

[0005] To address the aforementioned shortcomings in the existing technology, this utility model aims to provide a flame adjustment plate and a lighter, which has a simple production process, stable flame combustion, and can be used for a long time.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a flame regulating plate, comprising a flame regulating layer made of microfiber material, the flame regulating layer having a circular sheet structure, and a through hole being formed at its axial position.

[0007] As a limitation of this utility model: the microfiber material is microfiber leather.

[0008] As a limitation of this utility model: a lighter includes an outer shell with an opening at the top, a flame adjustment device, and an ignition switch fixedly installed at the upper end of the outer shell. The flame adjustment device includes a drain tube located inside the outer shell, an aluminum nail fixedly installed at the upper end of the drain tube, and a rotating screw fixedly installed at the lower part of the ignition switch. A flame adjustment plate is fixedly clamped between the aluminum nail and the rotating screw.

[0009] Due to the adoption of the above technical solution, the beneficial effects achieved by this utility model compared with the prior art are as follows: by using a single layer of microfiber material as a flame modulator, there is no need to use a pressing equipment to press multiple layers of materials into an integral structure. It is only necessary to cut out circular sheets of the corresponding size and install them into the ignition device for use, which simplifies the production process of the flame modulator and reduces the production cost.

[0010] Meanwhile, as the combustible gas rises, it can smoothly pass through the dense and uniform pore structure inside the microfiber material. Compared with multi-layer flame adjusters, the flame adjuster made of single-layer microfiber material reduces the obstruction to the combustible gas. Only one press of the switch is needed to allow the combustible gas to be fully discharged from the drain tube without causing flame spikes, making the flame burn more steadily. This not only saves the user time and effort in ignition, but also prevents the ignition switch from being damaged by frequent pressing, increasing the service life of the ignition device.

[0011] In addition, using microfiber materials with good air permeability, heat resistance, and aging resistance as the constituent materials of the flame modulator prevents the flame modulator from softening or decomposing after prolonged use of the ignition device, thus ensuring the flame modulator's function of regulating the flame.

[0016] The preferred embodiments of this utility model are described below with reference to the accompanying drawings. It should be understood that the flame adjuster and lighter described herein are preferred embodiments and are only used for illustration and explanation of this utility model, and do not constitute a limitation thereof.

[0017] The directional terms or positional relationships used in this utility model, such as "up," "down," "left," and "right," are based on the positional relationships in the accompanying drawings of this utility model. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component must have a specific orientation, or that it must be constructed and operated in a specific orientation.

[0018] Example 1

[0019] A flame modulator, such as Figure 1 As shown, the flame adjusting layer 1 includes a circular sheet structure, with a through hole 2 at the axial center of the flame adjusting layer 1 for the aluminum nail to pass through. Since the flame adjusting sheet in this embodiment is a single-layer sheet structure, it is not necessary to use a pressing device to press multiple layers of material into a single structure during the manufacturing process. Only a circular sheet of the appropriate size needs to be cut and installed into the ignition device for use. Therefore, the production process of the flame adjusting sheet is simplified, and production costs are reduced.

[0020] In this embodiment, the flame regulating layer 1 is made of microfiber material. Specifically, microfiber, also known as ultrafine fiber, uses a three-dimensional network structure of non-woven fabric as a matrix and undergoes a series of processing steps to obtain the microfiber material. Due to the dense and uniform porous structure within the microfiber material, combustible gas can pass smoothly through it during its ascent. Compared to multi-layered flame regulating plates, a flame regulating plate made of a single layer of microfiber material reduces the obstruction to combustible gas. Only one press of the switch is needed to allow the combustible gas to be fully discharged from the drainage tube, promoting stable flame combustion and preventing flame spikes. Therefore, the ignition device with the aforementioned flame regulating plate exhibits more stable flame combustion, saving users time and effort in ignition and preventing damage to the ignition switch after frequent pressing, thus increasing the lifespan of the ignition device.

[0021] After multiple experimental verifications, it was found that multi-layered flame modulators composed of polyurethane fabric and foam are prone to damage during mechanical assembly or flame adjustment, resulting in a high defect rate. In contrast, microfiber materials possess better toughness, breathability, and abrasion resistance, making them less susceptible to damage during mechanical assembly or flame adjustment, effectively reducing the defect rate. Furthermore, microfiber materials exhibit good heat resistance, cold resistance, and aging resistance. Using them as a component of the flame modulator prevents the internal flame modulator from softening or decomposing after prolonged use of the ignition device, thus ensuring the flame modulator's flame adjustment function. Further, the microfiber material can be microfiber leather or microfiber polyvinyl chloride; in this embodiment, microfiber leather is used.

[0022] When using a flame adjusting plate with the above structure, an aluminum nail is passed through the through hole 2, and the flame adjusting layer 1 is fixed between the rotating screw and the aluminum nail.

[0023] Example 2

[0024] A lighter includes an outer casing with an opening at the top, a flame adjustment device, and an ignition switch fixedly mounted on the upper part of the outer casing. Figure 2 As shown, the flame adjustment device includes a drain tube 3 located inside the housing, an aluminum nail 4 fixedly installed at the upper end of the drain tube 3, and a rotating screw 5 fixedly installed at the lower part of the ignition switch. The flame adjustment plate in Embodiment 1 is fixedly clamped between the aluminum nail 4 and the rotating screw 5.
