[0019] like Figure 1 As shown, a portable, efficient and multifunctional waste heat energy recycling alcohol gasification furnace device comprises a heating container support 1, an outer combustion chamber wall 2, a temperature difference power generation sheet 3, a heat dissipation fin 4, an outer wall 5, a pressure switch 6, a diaphragm pump 7, a sealing tank 8, a leg 9, a transmission pipe 10, a gasification spiral tube 11, a combustion nozzle 12, an inner gasification combustion chamber 13, an inner gasification combustion chamber air outlet 14, an inner gasification combustion chamber air inlet 15, a fuel alcohol filling port 16 and a voltage stabilizing module 17. The sealing tank 8 is arranged at the bottom of the inner gasification combustion chamber 13, and the gasification spiral tube 11, the inner gasification combustion chamber 13, the outer combustion chamber surrounded by the outer combustion chamber wall 2 and the outer combustion chamber surrounded by the outer wall 5 is arranged in sequence from the inside to the outside, there is a gap between the inner gasification combustion chamber 13, the outer combustion chamber and the outer wall, the outer side of the outer combustion chamber wall 2 is in close contact with the temperature difference power generation sheet 3, the outer side of the temperature difference power generation sheet 3 is in close contact with the heat dissipation fin 4, the outer periphery of the heat dissipation fin 4 is the outer wall and there is a gap between the two, the outer wall is fixed on the sealed tank 8, the gasification spiral tube 11 extends into the sealed tank 8 through the transmission tube 10, the sealed tank 8 is provided with a fuel alcohol filling port 16, the inside of the sealed tank 8 is connected with the diaphragm pump 7, the outer wall of the sealed tank 8 is provided with a pressure switch 6, the pressure switch 6 is connected in series with the temperature difference power generation sheet 3 and the diaphragm pump 7, and the temperature difference power generation sheet 3 is also connected with the voltage stabilizing module 17.

[0020] The heating container support 1 is made of 310S stainless steel and is located at the top of the alcohol gasification furnace device. It is distributed in three equal parts of 360 degrees on the top of the outer combustion chamber wall 2. Its function is to support various pots and containers so that the pots and containers are in the best position for heating.

[0021] The outer combustion chamber wall 2 is made of 310S stainless steel, located outside the inner gasification combustion chamber 13 and inside the thermoelectric power generation sheet 3. Most of the bottom is hollowed out in three equal parts of 360 degrees. The outer combustion chamber with an annular structure formed by the outer combustion chamber wall 2 directs most of the heat upwards by convection, and at the same time conducts heat to the thermoelectric power generation sheet 3 in the surrounding area by radiation.

[0022] The thermoelectric power generation sheet 3 is made of finished semiconductor products. Multiple thermoelectric power generation sheets 3 are densely distributed at 360 degrees and closely attached to the outer side of the outer combustion chamber wall 2. The side of the thermoelectric power generation sheet 3 away from the outer combustion chamber wall 2 is attached with a heat dissipation fin 4. The thermoelectric power generation sheet 3 is divided into multiple groups, each group is connected in series, and multiple groups are connected in parallel to make up for the low efficiency of a single thermoelectric power generation sheet 3. Under the action of the outer combustion chamber wall 2 and the heat dissipation fin 4, the two opposite sides of the thermoelectric power generation sheet 3 have a temperature difference to generate electrical energy to supply the diaphragm pump 7 to work. At the same time, when the alcohol gasification furnace device is in the best working state, it can generate excess electrical energy to supply the voltage stabilizing module 17 to charge mobile phones, etc.

[0023] The heat dissipation fins 4 are made of aluminum, densely distributed at 360 degrees and closely attached to the outside of the thermoelectric power generation sheet 3. Their function is to quickly dissipate the temperature of the outside of the thermoelectric power generation sheet 3, so that the temperature difference between the two sides of the thermoelectric power generation sheet 3 is as large as possible, providing driving power for the diaphragm pump 7.

[0024] The outer wall 5 is made of aluminum alloy and is located outside the heat sink fins 4 in a 360-degree ring shape. The lower part of the outer wall 5 and the upper part of the sealing tank 8 are connected to a sealed state, forcing the air flow to pass between the heat sink fins 4 and the outer wall 5, taking away the heat of the heat sink fins 4. At the same time, the air after initial heating enters the outer combustion chamber space surrounded by the outer combustion chamber wall 2 and the inner gasification combustion chamber 13 to participate in combustion and convection.

[0025] The pressure switch 6 is fixed on the upper part of one side of the sealed tank 8. The pressure switch 6 extends into the sealed tank 8, is connected to the temperature difference power generation sheet 3, and is connected in series with the diaphragm pump 7. The function is to detect the pressure of the sealed tank 8 through the pressure switch 6 and cut off or connect the circuit. When the air pressure in the sealed tank 8 is lower than the lower limit value of the pressure switch, the pressure switch 6 connects the circuit, and the electric energy generated by the temperature difference power generation sheet 3 is used as a power source to drive the diaphragm pump 7 to work and inflate and pressurize the sealed tank 8. When the pressure in the sealed tank 8 is higher than the upper limit value of the pressure switch, the pressure switch 6 cuts off the circuit, turns off the power supply, and stops the diaphragm pump 7 from working.

[0026] The diaphragm pump 7 is connected in series with the temperature difference power generation sheet 3 and the pressure switch 6. Its function is to inflate and pressurize the sealed tank 8 so that the alcohol in the sealed tank 8 enters the gasification spiral tube 11 through the transmission pipe 10 under the action of the air pressure and then is sprayed out from the combustion nozzle 12 for combustion.

[0027] The sealed tank 8 is made of aluminum alloy and is located on the top of the support leg 9. It is connected to the pressure sensing end of the pressure switch 6 and the output end of the diaphragm pump 7, and is connected to the fuel alcohol filling port 16. It serves as a container for fuel alcohol and maintains a sealed state to facilitate the storage of gaseous media.

[0028] The support leg 9 is made of aluminum alloy and is located at the bottom of the alcohol gasification furnace device. It is directly welded to the bottom of the sealed tank 8 and is distributed in three equal parts of 360 degrees concentric with the sealed tank 8. Its function is to stabilize the upright state of the device.

[0029] The transmission pipe 10 is made of aluminum alloy. The bottom end of the transmission pipe 10 is located at the bottom of the sealed tank 8. The top of the transmission pipe 10 passes through the upper part of the sealed tank 8 and is connected to the bottom of the gasification spiral tube 11. The passing part is welded and sealed. When there is pressure in the sealed tank 8, the fuel alcohol is sent to the gasification spiral tube 11 by pressure to participate in gasification and combustion.

[0030] The gasification spiral tube 11 is made of 310S stainless steel and is designed as an integrated unit with the combustion nozzle 12. At the same time, the gasification spiral tube 11 is connected to the transmission tube 10. The gasification spiral tube 11 is located inside the inner gasification combustion chamber 13. The function is to fully heat and gasify the fuel alcohol delivered by the transmission tube 10 by maximizing the heating surface of the spiral tube, and then the fuel alcohol is ejected in a gaseous state through the combustion nozzle 12 at the center of the gasification spiral tube 11 and burns violently. The gasification spiral tube 11 can gasify the alcohol to the greatest extent, thereby improving the combustion efficiency.

[0031] The combustion nozzle 12 is designed as an integral unit with the transmission pipe 10 and the gasification spiral tube 11, and is located at the center of the gasification spiral tube 11. The bottom of the combustion nozzle 12 is in a sealed state, and the top of the combustion nozzle 12 is connected to the gasification spiral tube 11. The three layers of the upper, middle and lower straight tube section of the combustion nozzle 12 each have 4 micropores, which are distributed in 4 directions and divided into four equal parts of 360 degrees in the straight tube section. The function is to spray and burn the fuel alcohol vaporized by the gasification spiral tube 11 from the combustion nozzle 12 in a gaseous state, thereby heating other related parts of the furnace body, and at the same time, the gasification spiral tube 11 performs heating circulation gasification combustion.

[0032] The internal gasification combustion chamber 13 is made of 310S stainless steel, is in the shape of an annular cup, and is fixed at the top center of the sealed tank 8. A plurality of internal gasification combustion chamber air outlet holes 14 are densely distributed on the upper side wall of the internal gasification combustion chamber 13 at 360 degrees, and its lower side wall is divided into three equal parts at 360 degrees, and most of the wall surface is hollowed out to form three internal gasification combustion chamber air inlets 15; there are gasification spiral tubes 11 and combustion nozzles 12 inside the internal gasification combustion chamber 13, which are used to preheat and start the device and use its structure to make the fuel alcohol burn more violently inside it.

[0033] The inner gasification combustion chamber outlet holes 14 are densely distributed 360 degrees on the upper part of the annular structure wall of the inner gasification combustion chamber 13, and are divided into two layers. The function is to make the flame ejected from the combustion nozzle 12 burn and radiate to the surroundings to make the heating more uniform.

[0034] The air inlet 15 of the internal gasification combustion chamber is located on the lower side wall of the internal gasification combustion chamber 13 and is distributed in three equal parts of 360 degrees. It is used to hollow out most of the wall of the internal gasification combustion chamber 13 to supplement oxygen and make the combustion in the internal gasification combustion chamber 13 more intense.

[0035] The fuel alcohol filling port 16 is designed to be integrated with the sealed tank 8 and is used to add fuel alcohol into the sealed tank 8 .

[0036] The voltage stabilizing module 17 is connected to the thermoelectric power generation chip 3 to stabilize the electric energy generated by the thermoelectric power generation chip 3 at 5V, thereby providing a stable charging voltage for electronic devices such as mobile phones.

[0037] The working principle of the present invention is:

[0038] When in use, first add a proper amount of high-purity fuel alcohol into the sealed can 8 from the fuel alcohol filling port 16, then cover the top cover of the sealed can 8 to make the sealed can 8 in a sealed state; pour fuel alcohol into the bottom of the inner vaporization combustion chamber 13 and ignite it for preheating. At this time, the alcohol burns in the inner vaporization combustion chamber 13 to generate heat, and the heat emerges from the upper opening of the inner vaporization combustion chamber 13 and the air outlet 14 of the inner vaporization combustion chamber. At the same time, the oxygen added through the air inlet 15 of the inner vaporization combustion chamber makes the alcohol in the inner vaporization combustion chamber 13 burn more fully, and radiates and heats the surrounding outer combustion chamber wall 2; the outer combustion chamber wall 2 is heated Then the heat is transferred to the thermoelectric sheet 3, and the heat is dissipated through the heat dissipation fins 4 on the outer layer of the thermoelectric sheet 3, so that a temperature difference is generated on both sides of the thermoelectric sheet 3, so that the thermoelectric sheet 3 generates electrical energy, which is used as the power supply of the diaphragm pump 7 and the charging power supply of electronic products, etc. The circuit is turned on or off by the pressure switch 6, and the diaphragm pump 7 is driven to inflate and pressurize the sealed tank 8. When the pressure in the sealed tank 8 reaches the upper limit, the power is turned off by disconnecting the pressure switch 6, so that the diaphragm pump 7 stops working. When the pressure in the sealed tank 8 is lower than the lower limit, the pressure switch 6 is turned on to start the diaphragm pump 7. The pressure in the sealed tank 8 rises, and the alcohol in the sealed tank 8 is pressed into the transmission pipe 10. At this time, the alcohol in the internal gasification combustion chamber 13 is still burning, and the spiral body of the gasification spiral tube 11 is heated, and the fuel alcohol passing through the gasification spiral tube 11 is gasified into a combustible gas, which is then ejected from the combustion nozzle 12 and ignited by the flame that continues to burn outside. When the device burns to the optimal state, the internal space surrounded by the outer combustion chamber wall 2 generates airflow due to heat convection, driving the air between the heat dissipation fins 4 and the outer wall 5 to flow to the internal space surrounded by the outer combustion chamber wall 2. The flowing air will take away the heat of the heat dissipation fins 4, so that the two sides of the thermoelectric power generation sheet 3 maintain a temperature difference state to generate electrical energy to drive the diaphragm pump 7 to inflate and pressurize the sealed tank 8. At the same time, the excess electricity generated by the thermoelectric power generation sheet 3 is stabilized at 5V through the voltage stabilizing module 17, which can be used for emergency charging of electronic devices such as mobile phones and tablets to improve their endurance.
