[0021] 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.
[0022] Please see Figures 1-5In this embodiment of the present invention, a self-pressurized high-efficiency energy-saving alcohol combustion device includes an alcohol tank 1, a heating coil 2, and an alcohol adding connector 17. The heating coil 2 is located at the center of the top of the alcohol tank 1. The heating coil 2 is a stainless steel tube with copper wire as filler inside. The bottom inlet of the heating coil 2 is fixedly connected to the top of the alcohol tank 1 by a nut. A first valve 3 is located at the bottom outlet of the heating coil 2 after a downward bend. The first valve 3 is fixedly connected to the top of the alcohol tank 1 by bolts. The outlet of the first valve 3 is located at the center of the heating coil 2. A flame furnace port 9 is located at the outlet of the first valve 3. Multiple small outlets are located at the outlet of the flame furnace port 9. The top of door 3 is equipped with a long pressure regulating handwheel 8. On the other side of the alcohol tank 1, opposite to the pressure regulating handwheel 8, a second valve 4 is connected by threads. The top of the second valve 4 is equipped with a rotating connector 16, and the top of the rotating connector 16 is rotatably connected to an alcohol adding connector 17. The top of the alcohol adding connector 17 is welded with a threaded connecting sleeve 18. The inside of the threaded connecting sleeve 18 is equipped with a hose that connects to the inlet of the second valve 4 through the rotating connector 16. The external alcohol bottle is connected to the threaded connecting sleeve 18 by threads, ensuring high airtightness. After opening the second valve 4, the alcohol bottle is inverted to allow alcohol to flow into the alcohol tank 1 without needing to turn off the alcohol stove, making it convenient to use.
[0023] Among them, a disc-shaped receiving plate 10 is welded to the bottom of the flame furnace opening 9. The outer diameter of the receiving plate 10 is larger than the circumference diameter of the heating coil 2, which can collect the alcohol liquid that is not fully burned at the beginning of ignition and prevent it from flowing and igniting foreign objects.
[0024] Among them, an electric igniter 5 is bolted to the side of the alcohol tank 1, located between the first valve 3 and the second valve 4. An L-shaped guide tube 6 is provided on the top of the electric igniter 5. The outlet of the guide tube 6 is close to the flame furnace opening 9. The igniter can preheat the flame furnace opening 9 and ignite the volatile alcohol, improve the ignition efficiency, and make it safer to use.
[0025] The alcohol tank 1 has four connecting ears 11 evenly welded to the top of its side. The connecting ears 11 have square fixing holes inside. An L-shaped bracket 12 with a square cross-section is slidably connected inside the connecting ears 11. A small corner is vertically set at the top of the short side of the bracket 12 so that the heating container can slide off the bracket 12. A circular limiting plate is set in the middle of the long side of the bracket 12 to facilitate the installation and disassembly of the bracket 12.
[0026] Among them, the bottom of the alcohol tank 1 is glued with a wooden heat insulation pad 7 to prevent the alcohol tank 1 from overheating and burning the table surface.
[0027] The bottom of the heat insulation pad 7 is provided with a cross-shaped storage groove 14. A cylindrical magnet 15 is embedded in the center of the storage groove 14. Metal support rods 13 are rotatably connected to the top of the four sides of the storage groove 14. The metal support rods 13 can increase the grounding area of the alcohol tank 1, making it more stable and preventing it from tipping over.
[0028] The working principle of this utility model is as follows: First, the support rod 13 at the bottom of the alcohol tank 1 is flipped to a horizontal position, so that the alcohol tank 1 is placed stably on the workbench. The first valve 3 and the electric igniter 5 are opened. The flame emitted by the electric igniter 5 is sprayed through the guide tube 6 towards the flame furnace opening 9, causing the flame furnace opening 9 and the heating coil 2 to heat up. After the heating coil 2 is preheated, it is easier to ignite for the first time. The alcohol in the heating coil 2 enters the heating coil 2 under capillary action and is heated to form gas, which is sprayed out from the flame furnace opening 9. The alcohol gas is ignited by the flame of the electric igniter 5. Then the electric igniter 5 is turned off. Due to the high temperature of the flame from the flame furnace opening 9, the pressure inside the alcohol tank 1 automatically increases, thereby... The system ensures a continuous flow of alcohol. Adjusting the first valve 3 regulates the flame size. The heating container is placed on top of the support 12 for heating, making it convenient to use. When little alcohol remains in the alcohol tank 1, the pressure decreases, and the flame at the burner nozzle 9 diminishes. Without shutting down the alcohol heater, the external alcohol bottle is threaded into the threaded sleeve 18 on the alcohol adding connector 17. This ensures a good seal and prevents spillage. Rotating the alcohol adding connector 17 inverts the alcohol bottle, and opening the second valve 4 allows the alcohol in the bottle to enter the alcohol tank 1 through the hose and the second valve 4 for refueling. This method is convenient and safe. The above description is merely a preferred embodiment of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
