Description

Technical Field

[0001] The utility model belongs to the technical field of lighter accessories, in particular to an air outlet portion and a lighter gasification furnace which are easy to process. Background Art

[0002] A lighter gasifier typically consists of an air mixing tube, an outlet section, an insulating cup, and a conductive structure. The tail of the outlet section plugs into the air mixing tube, while the head of the outlet section extends into the insulating cup. The gas in the gas tank assembly mixes with air through the air mixing tube. The mixed gas is then sprayed into the insulating cup through the outlet section. When the conductive structure is energized, sparks fly into the insulating cup, igniting the mixed gas inside and forming a flame.

[0003] The existing gas outlet part is an injection head recorded in the lighter gasification furnace with a straight through hole and a side hole injection head disclosed in application number CN201721042175.4, which has a straight through hole vertically passing through the injection head, and a side hole on its side wall connecting the straight through hole and the inner cavity of the insulation cup.

[0004] During the production and processing of the air outlet part, the main structure and straight-through holes are generally punched out by a machine tool first, and then the side holes are punched. It can be seen that the production and processing of the air outlet part is divided into two steps, and there is still room for improvement in processing efficiency. Utility Model Content

[0008] Preferably, the through hole is a variable diameter hole that is larger at the bottom and smaller at the top.

[0009] Preferably, the variable diameter hole includes large holes and small holes distributed from bottom to top, and the main body section is connected to the large holes.

[0010] Preferably, the extension section is connected to the large hole; or, the extension section is connected to both the large hole and the small hole.

[0011] And an air outlet portion that is easy to process, including a main body, a straight through hole is provided on the main body, and a side hole connected to the straight through hole is provided on the side of the main body. The straight through hole is a variable diameter hole that is larger at the bottom and smaller at the top. The upper side of the side hole passes through the upper end surface of the main body, and the upper side of the side hole is spaced from the upper end of the variable diameter hole.

[0012] Preferably, the variable diameter hole includes a large hole and a small hole distributed from bottom to top, the side hole is connected to the large hole, and the upper side of the side hole is spaced from the upper end of the small hole.

[0013] Preferably, an extension tube surrounding the small hole is integrally provided on the upper end surface of the main body, and the outer diameter of the extension tube is smaller than or equal to the inner diameter of the large hole.

[0014] Preferably, the inner diameter of the extension tube is consistent with the inner diameter of the small hole.

[0016] Compared with the prior art, the advantages of the present invention are:

[0017] 1. In this technical solution, the upper side of the side hole is connected to the step surface. When the main structure and the through hole are stamped through the Haval die, the side hole can be stamped simultaneously, eliminating the need for secondary processing of the side hole. This simplifies the processing technology, improves the processing efficiency, and helps improve the consistency of the output gas outlet.

[0018] 2. Compared with conventional side holes, the side holes in this technical solution are larger, which helps more mixed gas flow into the insulation cup through the side holes to form a combustion-supporting mixed gas, thereby ensuring the ignition rate;

[0019] 3. The design of the stepped surface helps to reduce material costs, and at the same time, it can also extend the distance between the side hole outlet end and the straight hole outlet end, avoiding the adhesion of the flame roots of the mixed gas flowing out of the two holes after being ignited to form a flame, that is, the flame formed by ignition is better in fullness.

[0032] In this embodiment, at least two side holes 12 are provided, all of which are evenly spaced along the circumference. The provision of multiple side holes 12 helps improve the uniformity of the distribution of the combustion-supporting mixed gas. Accordingly, the step surface 13 can be a continuous annular shape, with all of the side holes 12 communicating with this step surface 13. Alternatively, there can be multiple step surfaces 13 evenly spaced along the circumference, with each step surface 13 corresponding to each of the side holes 12, and the upper sides of the side holes 12 communicating with the corresponding step surface 13. Preferably, the step surface 13 is a continuous annular shape, which facilitates production and processing and helps reduce material costs.

[0033] In this embodiment, the main body 1 is cylindrical or in the shape of a regular polygonal column, preferably cylindrical.

[0034] Example 2: Figure 1 and Figure 2 As shown, the rest of the parts are the same as those in Example 1, except that the side hole 12 includes a main body section 121 and an extension section 122, the main body section 121 is connected to the straight hole 11, the extension section 122 is located on the upper side of the main body section 121, the extension section 122 is connected to the step surface 13, and is connected to the straight hole 11.

[0035] In this embodiment, the through hole 11 is a variable diameter hole that is larger at the bottom and smaller at the top. Furthermore, the variable diameter hole includes a large hole 111 and a small hole 112 distributed from bottom to top, and the main body section 121 is connected to the large hole 111.

[0036] In this embodiment, the extension section 122 is connected to both the large hole 111 and the small hole 112. Of course, the extension section 122 may also be connected only to the large hole 111 (see Figure 3 ), depending on the actual situation, in order to achieve a good exhaust effect.

[0037] Example 3: Figure 4 and Figure 5 As shown, a gas outlet portion that is easy to process includes a main body 1, which is provided with a vertical through hole 11. The through hole 11 is a variable diameter hole that is larger at the bottom and smaller at the top. A side hole 12 is provided on the side of the main body 1 and is connected to the through hole 11.
