Description

Technical Field

[0001] This utility model relates to the technical field of lighter accessories, and in particular to a gasification furnace gas outlet and a gasification furnace. Background Technology

[0002] In the prior art, the gasification furnace of a direct-fire lighter typically consists of an air mixing pipe, a nozzle, and a combustion chamber. The gas storage tank assembly, air mixing pipe, nozzle, and combustion chamber are connected in sequence. The gas in the gas storage tank assembly is mixed with air through the air mixing pipe. The mixed gas is then sprayed into the combustion chamber through the nozzle. The ignition device emits a spark that is directed into the combustion chamber, igniting the mixed gas in the combustion chamber into a flame.

[0003] Existing direct-fire lighters produce a straight "1"-shaped flame with a high temperature at the center, which can lead to excessive burning and waste when used to light cigars. Furthermore, the flame shape in existing lighters is monotonous and lacks aesthetic appeal. Summary of the Invention

[0004] To address the aforementioned problems, the present invention aims to provide a gasifier outlet and a gasifier. Compared to the gasifiers of traditional direct-fire lighters, the gasifier outlet of the present application improves the shape and arrangement of the main gas outlet, thereby providing a flame of a different shape and reducing the intensity of the flame center to prevent excessive burning when lighting a cigar.

[0005] A gasifier outlet section has an outer surface recessed inward to form a plurality of first grooves distributed circumferentially, the lower ends of the first grooves extending to the lower end face of the outlet section; one of the upper and lower end faces of the outlet section is provided with a plurality of first gas outlet holes, which are circumferentially distributed around the center line of the outlet section and positioned close to the center line; the other of the upper and lower end faces of the outlet section is provided with a plurality of second gas outlet holes, which correspond one-to-one with the first gas outlet holes and are connected, and are circumferentially distributed around the center line of the outlet section and positioned close to the bottom of the first grooves.

[0006] Preferably, the corresponding second air outlet and the first air outlet are connected by an inclined air outlet channel.

[0007] Preferably, six first air outlets and six second air outlets are provided.

[0008] Another object of this application is to provide a gasifier, including a gasifier outlet section and an air mixing pipe as described in any of the preceding claims, wherein the outlet end of the air mixing pipe is connected to a plurality of first outlet holes on the lower end face of the gas outlet section.

[0009] In existing gasifiers, the gas outlet section has only one large main gas outlet along its centerline. This application adopts the aforementioned solution, eliminating the main gas outlet along the centerline and instead providing multiple small gas outlets arranged around it. This disperses the gas output from the gas outlet section, reducing the heat at the flame center and preventing excessive burning when igniting cigars. Simultaneously, this dispersed arrangement increases the circumferential area of ​​the flame, increasing the contact area between the flame and the cigar, making it suitable for igniting larger diameter cigars. Furthermore, because the first and second gas outlets are offset radially within the gas outlet section, the gas passage connecting them is inclined. Consequently, part of the mixed gas from the gas outlet section is vertically upward from the first groove, while the other part is inclined upward through the first and second gas outlets, resulting in a flower-shaped flame.

[0017] First groove 11, first vent 12, second vent 13. Detailed Implementation

[0018] The embodiments of this utility model are described in detail below.

[0019] like Figure 1 and Figure 2As shown, this embodiment relates to a gas outlet section of a gasifier. The outer side of the gas outlet section is recessed inward to form a plurality of first grooves 11 distributed along the circumferential direction. The lower end of the first grooves 11 extends to the lower end face of the gas outlet section. One of the upper end face and the lower end face of the gas outlet section is provided with a plurality of first gas outlet holes 12. The plurality of first gas outlet holes 12 are circumferentially distributed with the center line of the gas outlet section as the center and are arranged close to the center line of the gas outlet section. The other of the upper end face and the lower end face of the gas outlet section is provided with a plurality of second gas outlet holes 13. The second gas outlet holes 13 correspond one-to-one with the first gas outlet holes 12 and are connected. The second gas outlet holes 13 are circumferentially distributed with the center line of the gas outlet section as the center and are arranged close to the bottom of the first grooves 11.

[0020] Example 1:

[0021] In this embodiment, the first vent 12 is located on the lower end face of the vent section, and the second vent 13 is located on the upper end face of the vent section. Because the vent section in this embodiment is structured as described above, the multiple vents located on the lower end face of the vent section are positioned close to the centerline of the vent section. Based on the gas transmission direction from the air mixing pipe to the vent section, more mixed gas can enter the first vent 12 and then be discharged through the second vent 13, ensuring sufficient gas output from the vent section. The multiple second vents 13 are positioned close to the bottom of the first groove 11, thereby dispersing the flame outwards, reducing the firepower at the flame center, and increasing the flame width. Furthermore, because the mixed air discharged from the second vents 13 is inclined upwards, the final flame of the vent section includes both inclined and straight upward shapes, resulting in a flower-like flame shape that is aesthetically pleasing. The final flame shape presented in this embodiment is as follows: Figure 3-4 As shown, the central vent is not provided, the central flame is eliminated, and the flame width is increased.

[0022] In this embodiment, the corresponding second air outlet 13 and the first air outlet 12 are connected by inclined air outlet channels. Therefore, due to the radial offset between the first air outlet 12 and the second air outlet 13 in the air outlet section, and the inclined air outlet channel connecting the first air outlet 12 and the second air outlet 13, part of the mixed gas delivered from the air outlet section is vertically upward from the first groove 11, and the other part is inclinedly upward through the first air outlet 12 and the second air outlet 13, ultimately resulting in a flower-shaped flame. Figure 3-4 As shown.

[0023] After the gasifier outlet section of the gasifier in this embodiment is installed, a plurality of first outlet holes 12 are aligned with the outlet end of the air mixing pipe. Preferably, after the gas outlet section is installed, the centerline of the gas outlet section coincides with the centerline of the air mixing pipe, and the outer diameter of the circle containing the plurality of first outlet holes 12 is the same as or slightly smaller than the diameter of the outlet hole at the outlet end of the air mixing pipe, thereby ensuring that a sufficient amount of mixed air enters the first outlet hole 12.

[0024] In this embodiment, six first air vents 12 and six second air vents 13 are provided respectively; the diameters of the first air vents 12 and the second air vents 13 are between 0.8mm and 1.2mm. In a preferred embodiment, the diameter between the first air vents 12 and the second air vents 13 is 1mm. This arrangement, through the matching of the number and size of the air vents, ensures sufficient air intake from the first air vents 12 and guarantees the final flame shape. Example 2:

[0025] The difference between this embodiment and Embodiment 1 is that the first vent 12 is located on the upper end face of the vent section, and the second vent 13 is located on the lower end face of the vent section. With this arrangement, since there is no central vent at the lower end of the vent section, the multiple second vents are located close to the outer end of the vent section. The mixed gas delivered from the air mixing pipe diffuses outward into the second vents. Although the multiple first vents are located close to the centerline of the vent section, compared to the prior art scheme with a central vent, less mixed gas enters the second vents. Although the flame in this embodiment still has a central flame, the intensity of the central flame is smaller, and the actual flame shape is as follows: Figure 5-6 As shown.

[0026] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
