[0031] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0032] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. 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 element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0033] Example 1: As Figures 1 to 3 As shown, an air outlet includes a lower cylinder 1 capable of carrying a large airflow and an upper cylinder 2 capable of carrying a small airflow. The lower cylinder 1 and the upper cylinder 2 are located on the same axis. The lower cylinder 1 is provided with at least two protruding ribs 3, and all the protruding ribs 3 are distributed along the circumferential direction. The upper cylinder 2 is located between all the protruding ribs 3. A gap is left between the lower cylinder 1 and the upper cylinder 2 to form a lateral flow channel. All the protruding ribs 3 divide the flow channel into multiple side holes 4. A groove 5 is formed between two adjacent protruding ribs 3. The groove 5 corresponds to and is connected to the side hole 4. A ring 6 is provided on the outer side of the upper cylinder 2. The ring 6 is located directly above all the grooves 5.

[0034] In this embodiment, four protruding ribs 3 are provided. The four protruding ribs 3 are evenly distributed along the circumferential direction and extend along the vertical direction. The lower end face of the protruding rib 3 is integrally formed with the upper end face of the lower cylinder 1, which facilitates one-time stamping forming by Haval mold.

[0035] The annular ring 6 is used to block the combustion-supporting mixed gas flowing upward along the edge groove 5, reduce the flow rate of the combustion-supporting mixed gas, and make the combustion-supporting mixed gas in this part diffuse outward, so as to improve the uniformity of the combustion-supporting mixed gas distribution in this area, avoid the situation that the combustion-supporting mixed gas is too little in a local area, and ensure that the combustion-supporting mixed gas is sufficient on the movement track of the spark, which is easy to be ignited, and helps to ensure the ignition rate.

[0036] It should be noted that the convex rib 3 is used to connect the lower cylinder 1 and the upper cylinder 2, and the electric conduction can be conducted through the convex rib 3 or through the annular ring 6. Specifically, the inner section of the existing electric conduction cup 8 (see Figure 13 ) is cancelled in the technical solution, and the annular ring 6 cooperates with the electric conduction cup 8 to generate sparks for ignition when electrified, or the convex rib 3 cooperates with the electric conduction cup 8 to generate sparks for ignition. The inner section is described in the existing patent with the application number CN201720976426.X and the patent name of a lighter combustion head.

[0037] In addition, the convex rib 3, the upper cylinder 2, and the annular ring 6 can be integrally formed, which helps to simplify the processing technology, reduce the production cost, improve the production efficiency, and improve the consistency of the output gas part. Of course, the convex rib 3, the upper cylinder 2, and the annular ring 6 can also be integrally formed (see Figure 4 ), and then assembled after separate processing. The specific actual situation is determined.

[0038] Example two: as shown in Figures 1 to 3 , the remaining parts are the same as example one, and the difference is that the inner circle of the annular ring 6 is fixedly connected with the outer side surface of the upper cylinder 2, and preferably, the annular ring 6 is integrally formed with the upper cylinder 2; the lower end surface of the annular ring 6 is fixedly connected with the upper end surface of the convex rib 3, and preferably, the annular ring 6 is integrally formed with the convex rib 3.

[0039] Example three: as shown in Figure 1 and Figure 4 , the remaining parts are the same as example two, and the difference is that the lower end surface of the annular ring 6 abuts against the upper end surface of the convex rib 3.

[0040] In the technical solution, the upper cylinder 2 and the convex rib 3 are separately arranged, and the annular ring 6 is integrally arranged on the outer side surface of the upper cylinder 2. When assembled, the upper cylinder 2 is inserted between all the convex ribs 3, and the lower end surface of the annular ring 6 abuts against the upper end surface of the convex rib 3, which is relatively simple to operate.

[0041] Example four: as shown in Figure 5The rest is the same as example two, except that a gap is left between the lower end surface of the annular ring 6 and the upper end surface of the convex rib 3. The gap is arranged to facilitate the lateral diffusion of the combustion-supporting mixed gas to the upper area of the convex rib 3, and to help the combustion-supporting mixed gas diffuse uniformly.

[0042] Example five: as shown in Figure 6 and Figure 7 The rest is the same as example two, except that the outer side of the upper end surface of the upper cylinder 2 is concave downward to form an annular groove 21, and the annular ring 6 is sleeved at the annular groove 21. The annular ring 6 is in interference fit with the upper cylinder 2. At this time, the annular ring 6 and the upper cylinder 2 are arranged separately, and are separately processed before being assembled.

[0043] In this embodiment, the groove bottom of the annular groove 21 is flush with the upper end surface of the convex rib 3. After assembly, the annular ring 6 will abut against the upper end surface of the convex rib 3.

[0044] Example six: as shown in Figure 5 and Figure 7 The rest is the same as example five, except that the height of the groove bottom of the annular groove 21 is higher than the height of the upper end surface of the convex rib 3. After assembly, a gap is left between the lower end surface of the annular ring 6 and the upper end surface of the convex rib 3. The gap is arranged to facilitate the lateral diffusion of the combustion-supporting mixed gas to the upper area of the convex rib 3, and to help the combustion-supporting mixed gas diffuse uniformly.

[0045] Example seven: as shown in Figure 8 The rest is the same as example one, except that the lower end surface of the annular ring 6 is provided with an inclined guide surface 61 that inclines from inside to outside and upward. The arrangement of the inclined guide surface 61 helps guide the combustion-supporting mixed gas to flow obliquely upward to the movement track of the spark, ensuring that the spark contacts the combustion-supporting mixed gas more accurately and timely, and improving the ignition success rate.

[0048] In the technical solution, the circular ring 6 is used to block the combustion-supporting mixed gas flowing upward along the ridge groove 5, reduce the flow rate of the combustion-supporting mixed gas, and make the combustion-supporting mixed gas in this part diffuse outward, thereby improving the uniformity of the distribution of the combustion-supporting mixed gas in this area, avoiding the situation that the combustion-supporting mixed gas is too little in a local area, ensuring that the combustion-supporting mixed gas is sufficient in the movement track of the spark, easy to be ignited, and helping to ensure the ignition rate.

[0049] Compared with the first embodiment, the technical solution sets the circular ring 6 on the protrusion 3, and the inner circle of the circular ring 6 and the outer side surface of the upper cylinder 2 can be in abutment, fixed connection, or have a gap. When there is a gap between the circular ring 6 and the upper cylinder 2 (see Figure 11 ), the gap forms a pressure relief channel, and part of the combustion-supporting mixed gas flows upward through the pressure relief channel, which can play a pressure relief role.
