Description

Technical Field

[0001] The utility model belongs to the technical field of lighter accessories, and particularly relates to an air outlet head, an air outlet part and a gasification furnace. Background Technique

[0002] A direct-jet lighter is an ignition device, which generally includes a housing, a gas storage tank assembly, an ignition device, a direct-jet gasification furnace and a gas supply control mechanism. The direct-jet gasification furnace generally consists of an air mixing pipe, an air outlet part and a heat insulation cup. The gas storage tank assembly, the air mixing pipe, the air outlet part and the heat insulation cup are connected in sequence. The gas in the gas storage tank assembly is mixed with air through the air mixing pipe, and the mixed gas is sprayed into the heat insulation cup through the air outlet part. The ignition device emits a spark and shoots it towards the heat insulation cup to ignite the mixed gas in the heat insulation cup to form a flame.

[0003] The conventional air outlet part includes a connecting pipe and an air outlet head arranged at the top of the connecting pipe. For example, an air outlet part and a gasification furnace disclosed in the patent application No. CN202222133201.1. The air outlet part includes an upper sleeve. The outer side surface of the upper sleeve is recessed inward to form a plurality of first grooves distributed along the circumferential direction. The lower end of the first groove extends to the lower end surface of the upper sleeve, and air outlet holes communicating with the upper end surface of the upper sleeve are arranged on the upper end surface of the first groove. The technical solution has a relatively simple structure and helps to reduce production costs. However, the upper end surface of the upper sleeve is a plane, the upper end of the central hole and the upper end of the air outlet hole are on the same plane, and there is no blocking object between them. The mixed gas ejected from the air outlet hole may gather towards the center and adhere to the mixed gas ejected from the central hole, forming a bundle of mixed gas with too high a concentration. The ratio of this bundle of mixed gas to the oxygen in the heat insulation cup is not coordinated and is not easy to ignite, resulting in a low ignition rate and poor user experience. Therefore, there is still room for improvement. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide an air outlet head, an air outlet part and a gasification furnace, which helps to improve the ignition rate.

[0005] The technical solution adopted by the utility model to solve the above technical problem is: an air outlet head, including a sleeve with a central hole, and a plurality of exhaust holes are arranged on the upper end surface of the sleeve, and the upper end surface of the central hole and the upper end surface of the exhaust holes are not on the same plane.

[0006] Preferably, the height of the upper end surface of the central hole is higher than the height of the upper end surface of the exhaust holes.

[0007] Preferably, the upper end surface of the sleeve is a first inclined surface that protrudes upward from the outside to the inside.

[0008] Preferably, the height of the upper end surface of the central hole is lower than the height of the upper end surface of the exhaust holes.

[0009] Preferably, the upper end face of the sleeve is a second inclined surface that is recessed downward from the outside to the inside.

[0010] Preferably, a plurality of strip-shaped grooves distributed along the circumferential direction are formed by inward recessing of the outer side surface of the sleeve. The lower ends of the strip-shaped grooves penetrate through the lower end face of the sleeve. The plurality of strip-shaped grooves correspond to the plurality of exhaust holes one by one, and the lower ends of the exhaust holes are communicated with the upper ends of the corresponding strip-shaped grooves.

[0011] Preferably, a prism is formed between two adjacent strip-shaped grooves. A support column is fixedly arranged at the lower end of the prism. The height of the lower end face of the support column is lower than the height of the lower end face of the sleeve.

[0012] And an air outlet part, including a connecting pipe and the above-mentioned air outlet head. An installation seat is fixedly arranged at the upper end of the connecting pipe. A slot is arranged at the upper end of the installation seat. A through hole communicated with the connecting pipe is arranged at the bottom of the slot. The lower part of the air outlet head is inserted into the slot.

[0013] And a gasifier, including a heat insulation cup, an air mixing pipe and the above-mentioned air outlet part. An installation hole is arranged at the bottom of the heat insulation cup. The lower end of the connecting pipe passes through the installation hole and then is inserted into the air mixing pipe. The installation seat and the air outlet head are both located inside the heat insulation cup.

[0014] Preferably, an air inlet hole is arranged in the middle of the air mixing pipe. A pressurizing cavity is arranged at the lower part of the air mixing pipe. A pressurizing sheet, a sealing ring, a filter screen and a rubber tail cap are sequentially arranged in the pressurizing cavity from top to bottom.

[0015] Compared with the prior art, the advantages of the present utility model are as follows:

[0016] 1. By arranging the upper end face of the central hole and the upper end face of the exhaust hole on different planes, the distance between the upper end face of the central hole and the upper end face of the exhaust hole is extended, avoiding or reducing the possibility that the mixed gas ejected from the exhaust hole gathers towards the center, ensuring that the mixed gas ejected from the exhaust hole can fully diffuse into the heat insulation cup to form a mixed gas for combustion support. The mixing ratio of this part of the mixed gas and the oxygen in the heat insulation cup is relatively appropriate, easy to ignite, and helps to improve the ignition rate;

[0017] 2. After the mixed gas ejected from the central hole is ignited to form a central main flame, and the mixed gas ejected from the exhaust hole is ignited to form a flame for combustion support, after staggering the upper end face of the central hole and the upper end face of the exhaust hole, the root of the central main flame will not be adhered to the root of the flame for combustion support, and the fullness of the ignited flame is better.

[0028] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model. In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0029] Embodiment 1: As Figure 1 andFigure 2 As shown in the figure, an air outlet head includes a sleeve 1 having a central hole 11. A plurality of exhaust holes 12 are provided on the upper end surface of the sleeve 1. The upper end surface of the central hole 11 and the upper end surface of the exhaust holes 12 are not in the same plane.

[0030] In this embodiment, the plurality of exhaust holes 12 are distributed around the central hole 11. The exhaust holes 12 can be formed on the air outlet head or formed by the cooperation of the air outlet head and a fire suppression ring 2.

[0031] Embodiment Two: As Figures 1 to 3 shown in the figure, the rest is the same as that of Embodiment One, and the difference is that the height of the upper end surface of the central hole 11 is higher than the height of the upper end surface of the exhaust holes 12.

[0032] In this embodiment, the upper end surface of the sleeve 1 is a first inclined surface 13 that bulges upward from the outside to the inside.

[0033] The mixed gas ejected from the exhaust holes 12 first diffuses. During the upward diffusion process, part of it may gather towards the center direction, but the rest of the mixed gas can diffuse into the heat insulation cup 5 to form the mixed gas for combustion support. The mixing ratio of this part of the mixed gas and the oxygen in the heat insulation cup 5 is relatively appropriate, easy to ignite, and helps to improve the ignition rate.

[0034] Embodiment Three: As Figure 4 and Figure 5 shown in the figure, the rest is the same as that of Embodiment One, and the difference is that the height of the upper end surface of the central hole 11 is lower than the height of the upper end surface of the exhaust holes 12.

[0035] In this embodiment, the upper end surface of the sleeve 1 is a second inclined surface 14 that depresses downward from the outside to the inside.

[0036] During the process of the mixed gas ejected from the central hole 11 passing through the second inclined surface 14, its flow rate will gradually slow down and certain diffusion will occur, thereby reducing the influence on the mixed gas ejected from the exhaust holes 12 and ensuring that the mixed gas ejected from the exhaust holes 12 can diffuse into the heat insulation cup (see Figure 3 ) to form the mixed gas for combustion support. The mixing ratio of this part of the mixed gas and the oxygen in the heat insulation cup 5 is relatively appropriate, easy to ignite, and helps to improve the ignition rate.

[0037] Embodiment Four: As Figure 6 shown in the figure, the rest is the same as that of Embodiment One, and the difference is that a plurality of strip-shaped grooves 15 distributed along the circumferential direction are formed by the inward depression of the outer side surface of the sleeve 1. The lower ends of the strip-shaped grooves 15 penetrate through the lower end surface of the sleeve 1. The plurality of strip-shaped grooves 15 correspond to the plurality of exhaust holes 12 one by one, and the lower ends of the exhaust holes 12 are communicated with the upper ends of the corresponding strip-shaped grooves 15.

[0038] In this embodiment, a prism 16 is formed between two adjacent strip grooves 15, and a support column 17 is fixedly disposed at the lower end of the prism 16, and the height of the lower end surface of the support column 17 is lower than the height of the lower end surface of the sleeve 1. Preferably, the support column 17 and the prism 16 are integrally formed.

[0040] In this embodiment, the mounting seat 4 and the connecting pipe 3 are integrally formed, which is easy to process and helps to improve production efficiency.

[0041] Example 6: Figure 3 As shown, a gasification furnace includes an insulating cup 5, an air mixing tube 6 and the air outlet portion disclosed in Example 5. The bottom of the insulating cup 5 is provided with a mounting hole 51. The lower end of the connecting tube 3 passes through the mounting hole 51 and is inserted into the air mixing tube 6. The mounting seat 4 and the air outlet head are both located in the insulating cup 5.

[0042] In this embodiment, an air inlet hole 61 is provided in the middle of the air mixing tube 6, and a boosting cavity 62 is provided at the lower part of the air mixing tube 6. A boosting plate 71, a sealing ring 72, a filter screen 73 and a rubber tail cap 74 are provided in the boosting cavity 62 from top to bottom.
