Description

Technical Field

[0001] This utility model relates to the field of stove burner head technology, specifically an alcohol-based fuel stove burner head. Background Technology

[0002] Alcohol-based fuel stoves are mainly used in commercial catering kitchens, with liquid methanol as the primary fuel. They are mainly divided into gasification stoves and atomization stoves. Gasification stoves require a fan to mix the fuel with air and spray it out, which is then ignited by an ignition needle. The flame is emitted from the burner head, thus achieving combustion and heating. To ensure complete combustion of the liquid fuel, a separate gasification chamber is installed in the burner head. During fuel combustion, the gasification chamber is heated, causing the particulate fuel to further vaporize at high temperatures within the chamber, resulting in complete combustion. However, the gasification chamber design also leads to more components in the existing gasification stove burner head, increasing its cost.

[0003] To optimize the structure of the gasification stove burner head and ensure complete combustion of fuel, we designed this stove burner head with an integrated gasification chamber inside the burner head liner. Through cooperation with the baffle cover, the fuel can be fully gasified and burned in the gasification chamber, improving combustion efficiency. There is no need to set up a separate gasification chamber in the burner head liner, which optimizes the internal structure of the burner head, reduces processing costs, and is highly practical.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0028] Please see Figure 1-8 This embodiment provides an alcohol-based fuel stove burner, including an outer shell 1, and a burner inner liner 2 inside the outer shell 1. The burner inner liner 2 has a communicating ignition chamber 4, a mixing chamber 6, a gasification chamber 11 and a flame-spraying chamber 18 arranged sequentially from bottom to top inside the burner inner liner 2. A guide air chamber 3 is provided between the burner inner liner 2 and the outer shell 1.

[0029] The ignition chamber 4 is used to house the fuel nozzle and the ignition needle for ignition. As a conventional setting familiar to those skilled in the art, an ignition needle mounting hole 5 is provided on the outer wall of the ignition chamber 4 for installing the ignition needle. The nozzle extends from the bottom of the ignition chamber 4. This is a conventional and universal design and will not be described in detail.

[0030] Mixing chamber 6 is used to achieve thorough mixing of fuel and air, such as... Figure 1 as well as Figure 3-5 As shown, the outer wall of the mixing chamber 6 is provided with guide holes that communicate with the guide air chamber 3. These mainly consist of the first guide hole 7 on the side wall and the second guide hole 8 at the bottom, which are conventional settings familiar to those skilled in the art.

[0031] In this application, the gasification chamber 11 and the furnace inner liner 2 are integrated into a single design to achieve fuel particle gasification. It is located between the mixing chamber 6 and the flame chamber 18. Figure 1 as well as Figure 3-6As shown, the upper end of the outer wall of the gasification chamber 11 is provided with a guide hole communicating with the guide air chamber 3, which is the third guide hole 12 shown in the figure. This hole has the same function as the transverse air hole on a conventional gasification chamber, which is used to make the fuel and the air in the guide air chamber 3 more fully combined, thereby improving the combustion efficiency. In order to enable the gasification chamber 11 to heat up quickly and to allow the fuel particles to stay inside for a sufficient time to ensure the gasification effect, an upper gasification chamber cover plate 13 is fixed at the upper end of the gasification chamber 11. In order to ensure its ventilation, multiple fourth guide holes 14 are evenly opened on the periphery of the upper gasification chamber cover plate 13. At the same time, in order to further improve the gasification effect of the gasification chamber 11, a lower gasification chamber cover plate 9 is fixed at the lower end of the gasification chamber 11. Multiple lower guide holes 10 are evenly opened on the periphery of the lower gasification chamber cover plate 9. As is common knowledge familiar to those skilled in the art, the lower gasification chamber cover plate 9 can be placed as needed.

[0032] As a conventional design for the burner head, the flame-spraying chamber 18 is used to spray flames. A sixth guide hole 19 is also provided in the inner liner 2 of the burner head to connect the guide air chamber 3 and the flame-spraying chamber 18. An air outlet filter 15 is fixed at the upper end of the flame-spraying chamber 18. A fifth guide hole 16 is provided on the air outlet filter 15. A flame-collecting ring 17 is provided at the upper end of the inner liner 2 of the burner head, located around the air outlet filter 15. The above design is a conventional structure used to make the flames sprayed from the flame-spraying chamber 18 uniform and concentrated. This application will not elaborate further.

[0033] It should be noted that after the burner head is ignited, the temperature inside the gasification chamber 11 can be rapidly increased by the cooperation of the upper gasification chamber cover plate 13 and the lower gasification chamber cover plate 9, so that the unburned fuel particles are gasified and then mixed with air for complete combustion. Its working principle is common knowledge familiar to those skilled in the art and is the same as the working principle of existing burners, so this application will not elaborate further.

[0034] It should be noted that the above embodiments are only specific and clear descriptions of the technical solutions and features of this application.
