Description

Technical Field

[0001] This utility model relates to the field of atomizer technology, and in particular to a portable dry-burning atomizer based on hybrid heating and dynamic thermal management. Background Technology

[0002] Most existing dry burners use resistance heating, which involves passing an electric current through a heating element or conductive medium, such as a resistance wire, a thermistor (PTC), or a heating film, causing the heating element to heat up first. The heat generated by the heating element is then used to heat the target object. Existing devices often use nickel-chromium alloy (NiCr) or iron-chromium-aluminum alloy (FeCrAl) as the resistance wire, which is wound around a ceramic cup or metal support to form a heating plate or coil, directly or indirectly heating the target object. However, this method can easily cause localized carbonization of the target object, releasing harmful substances (such as benzene). Furthermore, resistance wire heating usually has low energy efficiency, as some electrical energy is converted into heat, while the rest is wasted on the resistance element itself.

[0028] Reference Figures 1 to 6 As shown, a portable dry-burning atomizer based on hybrid heating and dynamic thermal management includes a main body 1, an upper structure 2, a base 3, and a heating device 4. The upper structure 2 is placed on the main body 1 and the heating device 4, and the base 3 is placed at the bottom of the main body 1 and connected to the main body 1. The heating device 4 is placed on the main body 1 and includes an oven 5, a heat insulation tube 6, and a shell 7. The shell 7 is placed on the main body 1, the heat insulation tube 6 is placed inside the shell 7, the oven 5 is placed inside the heat insulation tube 6, and a heating coil 9 is provided inside the heat insulation tube 6. One end of the heating coil 9 is placed inside the oven 5, and the other end of the heating coil 9 is placed inside the heat insulation tube 6.

[0029] The main body 1 includes a support 11 and a top cover 12. The top cover 12 is placed on the support 11 and the outer shell 7. A first through hole 13 is provided on the top cover 12. The first through hole 13 is located above the oven 5. An oven cover 14 is provided inside the first through hole 13. The oven cover 14 is placed on the oven 5. A through hole is provided on the oven cover 14 directly above the oven 5.

[0030] A support rod 61 is installed inside the heat insulation tube 6. One end of the support rod 61 passes through the heating coil 9 and is connected to the oven 5. The other end of the support rod 61 passes through the outer shell 7 and is connected to the base 3. The heating coil 9 is placed on the support rod 61, which supports the oven 5 and fixes the positions of the oven 5 and the heating coil 9, so that the heating coil 9 can heat the oven 5 better.

[0031] The oven 5 has a cavity with several second through holes 51 at the bottom. The hot gas generated by the heating coil 9 enters the oven 5 through the second through holes 51 to heat the material inside. The current flows from the center of the heating coil 9 outward, which means that the heating coil 9 is hottest in the middle and the temperature gradually decreases as it moves away from the center. Since the heating coil 9 only contacts the oven 5 through its outer surface, the temperature of the oven 5 is always lower than the average air temperature that passes through the heating coil 9 and is calibrated for extraction. Therefore, the conduction temperature is always lower than the convection temperature.

[0032] The upper structure 2 includes a first housing 21, a second housing 22, a gas regulating valve 23, and a suction nozzle 24. The first housing 21 is placed on the upper cover 12, and the second housing 22 is placed on the first housing 21. The first housing 21 is located above the oven 5 and has a fifth through hole 25. Several layers of filter screens 26 are arranged in the fifth through hole 25. The gas regulating valve 23 is placed on the second housing 22, and the suction nozzle 24 is placed on the gas regulating valve 23. The fifth through hole 25 is in communication with the gas regulating valve 23, and the suction nozzle 24 is in communication with the gas regulating valve 23. The material in the oven 5 is heated and atomized. The atomized gas enters the fifth through hole 25 of the first housing 21. The filter screens 26 in the fifth through hole 25 filter the atomized gas. The filtered atomized gas passes through the fifth through hole 25, through the first housing 21, and into the gas regulating valve 23. It is then sucked out through the suction nozzle 24.

[0033] A stirring rod 16 is also provided on the upper cover 12. The stirring rod 16 is used to stir the material in the oven 5 and can also be used to clean the oven 5 and remove the residue left after the material in the oven 5 is heated. A locking gear 27 is also provided on the second housing 22. One end of the locking gear 27 passes through the second housing 22 and is connected to the first housing 21. The position of the upper structure 2 is fixed by the locking gear 27, so that the upper structure 2 is fixed on the main body 1.

[0034] A control board 31 is installed inside the base 3. The base 3 has a display screen 32, control buttons 33, and a Type-C interface 34, all of which are electrically connected to the control board 31. A negative electrode 91 is installed on the coil 9, with one end connected to the coil 9 and the other end electrically connected to the control board 31. The display screen 32 shows the control options and the heating temperature and time of the heating coil 9. The heating temperature of the heating coil 9 is adjusted using the control buttons 33.
