[0015] This application includes at least one of the following beneficial technical effects:

[0016] 1. This application utilizes multiple first heating tubes and multiple second heating tubes in combination to heat the interior of the first heating chamber and the second heating chamber, thereby heating and melting the solid raw material placed in the first heating chamber into a liquid raw material. A filter screen can be used to intercept and filter the raw material material placed in the first heating chamber, allowing the liquid raw material to flow through the filter screen into the second heating chamber for further heating, and allowing the solid raw material to continue to be heated and melted inside the second heating chamber.

[0017] 2. This application utilizes an air delivery assembly consisting of a booster air pump, an air collection box, an air outlet pipe, a first air delivery pipe, a serpentine heat-conducting pipe, and a second air delivery pipe. This assembly controls the pressurized air to be ejected from multiple jet holes into the second heating chamber. Furthermore, by utilizing the thermal conductivity of the heat-conducting plate and the serpentine heat-conducting pipe, a portion of the heat from the multiple second heating pipes is sequentially transferred to the pressurized air through the pipe walls of the heat-conducting plate and the serpentine heat-conducting pipe, thereby heating the pressurized air. This results in hot pressurized air being ejected from the multiple jet holes into the second heating chamber, which in turn accelerates the evaporation of the liquid raw material inside the second heating chamber, forming a smoke state. The smoke then passes through the spray pipe and is finally ejected from the nozzle.

[0018] 3. This application utilizes a stirring mechanism composed of a drive shaft, a first horizontal shaft, multiple stirring blades, multiple arc-shaped blades, a connecting shaft, a second horizontal shaft, and multiple stirring blades. During the spraying of the atomized active ingredient, a portion of the kinetic energy in the pressurized air discharged from the outlet pipe can be converted into mechanical energy. This allows control of the rotation of the drive shaft, the first horizontal shaft, the multiple stirring blades, the multiple arc-shaped blades, the connecting shaft, the second horizontal shaft, and the multiple stirring blades. The rotation of the multiple stirring blades disperses and stirs the solid active ingredient material inside the first heating chamber, ensuring more even heating and accelerating the melting efficiency of the solid active ingredient material. The multiple stirring blades stir the atomized active ingredient material inside the second heating chamber, mixing the volatilized atomized active ingredient material evenly within the second heating chamber, improving the uniformity of the volatilized concentration of the atomized active ingredient material, and thus ensuring a uniform concentration of the atomized active ingredient material sprayed from the nozzle.

[0019] 4. This application utilizes a casing composed of an inner metal cylinder layer and an outer insulation layer, which enables the casing to have the advantages of high strength, resistance to breakage, effective prevention of heat loss, improved heating efficiency, and energy saving.

[0029] The technical solution of this application will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0030] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 This application provides a thermal fogging machine, including a barrel 1. The barrel 1 has a first heating chamber 2 and a second heating chamber 3. The first heating chamber 2 provides heating space for solid raw material, and the second heating chamber 3 provides heating space for melted liquid raw material. A partition 4 is fixedly installed inside the barrel 1 to separate the first heating chamber 2 and the second heating chamber 3. A filter screen 5 is fixedly installed at the bottom of the partition 4, and the bottom of the filter screen 5 is fixedly connected to the bottom inner wall of the first heating chamber 2. The filter screen 5 can intercept and block the raw material placed inside the first heating chamber 2, preventing the solid raw material from entering the second heating chamber 3.

[0031] The barrel 1 has two vertical cavities 6, with the first heating cavity 2 and the second heating cavity 3 located between them. Multiple equally spaced first heating tubes 7 are fixedly installed in each of the two vertical cavities 6. A horizontal cavity 8 is located below the first heating cavity 2 and the second heating cavity 3 within the barrel 1. A heat-conducting plate 9 is fixedly installed in the horizontal cavity 8, and multiple equally spaced second heating tubes 10 are fixedly installed on the top of the heat-conducting plate 9. The combined use of the multiple first heating tubes 7 and the multiple second heating tubes 10 allows for heating of the interior of the first heating cavity 2 and the second heating cavity 3. A feeding port 11 is provided on the inner top wall of the first heating cavity 2 for convenient placement of solid raw materials into the first heating cavity 2. An end cap 1 is threaded into the feeding port 11. 2. The feed port 11 can be sealed using the end cap 12. The barrel 1 is equipped with an air supply assembly for supplying pressurized air into the second heating chamber 3. The air supply assembly includes a booster pump 13, a gas collection box 14, an outlet pipe 15, a first air supply pipe 16, a serpentine heat-conducting pipe 17, and a second air supply pipe 18. The booster pump 13 and the gas collection box 14 are both fixedly installed on the left outer wall of the barrel 1. One end of the outlet pipe 15 is fixedly connected to the exhaust end of the booster pump 13, and the other end of the outlet pipe 15 extends into the gas collection box 14. The first air supply pipe 16 is fixedly installed at the bottom of the gas collection box 14 and communicates with the inside of the gas collection box 14. The serpentine heat-conducting pipe 17 is fixedly installed at the bottom of the heat-conducting plate 9, and the first air supply pipe 16 extends into the gas collection box 14. One end of the gas collecting box 14 extends into the transverse cavity 8 and is fixedly connected to one end of the serpentine heat-conducting pipe 17. The other end of the second gas supply pipe 18 is fixedly installed on the other end of the serpentine heat-conducting pipe 17. The end of the second gas supply pipe 18 away from the serpentine heat-conducting pipe 17 extends into the second heating chamber 3. Multiple jet holes 19 are opened at the end of the second gas supply pipe 18 located in the second heating chamber 3. The multiple jet holes 19 are evenly distributed. By utilizing the operation of the booster air pump 13, booster air can be delivered into the gas collecting box 14 through the air outlet pipe 15. The booster air entering the gas collecting box 14 then enters the serpentine heat-conducting pipe 17 through the first gas supply pipe 16. Utilizing the thermal conductivity of the heat-conducting plate 9 and the serpentine heat-conducting pipe 17, part of the heat from the multiple second heating pipes 10 can be transferred. The heat is transferred to the wall of the serpentine heat pipe 17, and then to the pressurized air flowing inside the serpentine heat pipe 17, thus heating the pressurized air. By utilizing the curved design of the serpentine heat pipe 17, the flow time of the pressurized air inside the serpentine heat pipe 17 can be increased, ensuring effective heating of the pressurized air. The heated pressurized air enters the second air delivery pipe 18 and is finally ejected from multiple jet holes 19, thereby accelerating the evaporation of the liquid raw material inside the second heating chamber 3 to form a smoke state. The smoke passes through the spray pipe 20 and is finally ejected from the nozzle 21. The barrel 1 is also equipped with a stirring mechanism for stirring the materials in the first heating chamber 2 and the second heating chamber 3. The stirring mechanism includes stirring component one and stirring component two.The stirring assembly includes a drive shaft 22, a first horizontal shaft 23, multiple stirring blades 24, and multiple arc-shaped blades 25. The drive shaft 22 is rotatably mounted on the left side wall of the barrel 1. The left end of the drive shaft 22 is located inside the gas collection box 14, and the right end of the drive shaft 22 is located inside the first heating chamber 2. The multiple arc-shaped blades 25 are all fixedly mounted on the left end of the drive shaft 22 and are distributed in a ring at equal intervals. The gas outlet pipe 15 is located directly above the arc-shaped blades 25. The multiple arc-shaped blades 25 can be used to pressurize the gas discharged from the gas outlet pipe 15. Part of the kinetic energy in the air is converted into mechanical energy, which in turn controls the rotation of the drive shaft 22, the first horizontal shaft 23, multiple stirring blades 24, and multiple arc-shaped blades 25. The rotation of the multiple stirring blades 24 disperses and stirs the solid raw material inside the first heating chamber 2, ensuring more even heating and accelerating the melting efficiency. The first horizontal shaft 23 is fixedly installed on the right end of the drive shaft 22. Multiple stirring blades 24 are all fixedly installed on the first horizontal shaft 23 and evenly distributed. A second stirring assembly is located on the right end of the first horizontal shaft 23. The second stirring assembly includes a connecting shaft 26, a second horizontal shaft 27, and multiple stirring blades 28. A mounting hole is provided on one side of the partition 4. The connecting shaft 26 rotates through the mounting hole via a bearing. The left end of the connecting shaft 26 is fixedly connected to the right end of the first horizontal shaft 23. The second horizontal shaft 27 is fixedly installed on the right end of the connecting shaft 26 and located inside the second heating chamber 3. Multiple stirring blades 28 are all fixedly installed on the second horizontal shaft 27 and evenly distributed. The rotation of the first horizontal shaft 23... This mechanism can drive the connecting shaft 26, the second horizontal shaft 27, and multiple stirring blades 28 to rotate. The stirring blades 28 agitate the raw material in a fume state inside the second heating chamber 3, increasing the flowability of the fume-state raw material and improving the uniformity of its volatile concentration within the second heating chamber 3. This ensures a uniform concentration of the fume-state raw material sprayed from the nozzle 21. A spray pipe 20, connected to the second heating chamber 3, is fixedly installed at the top of the barrel 1. A nozzle 21 is fixedly installed at the end of the spray pipe 20 furthest from the barrel 1.

[0032] In this embodiment, the barrel 1 includes an inner metal cylinder layer 101 and an outer insulation layer 102. The outer insulation layer 102 is fixedly connected to the outer wall of the inner metal cylinder layer 101. The inner metal cylinder layer 101 can be made of stainless steel, which gives the inner metal cylinder layer 101 good strength and thermal conductivity. The outer insulation layer 102 can be made of polyurethane, which gives the outer insulation layer 102 good thermal insulation performance, thereby effectively preventing heat loss, improving heating efficiency, and saving energy.

[0033] In this embodiment, the bottom inner wall of the first heating chamber 2 is higher than the bottom inner wall of the second heating chamber 3, so that the liquid raw material melted in the first heating chamber 2 can more easily and completely flow into the second heating chamber 3.

[0034] In this embodiment, the stirring blade 28 is provided with a plurality of evenly distributed vent holes 29, which can reduce the wind resistance when the stirring blade 28 rotates, making the rotation of the stirring blade 28 more stable and smooth.

[0035] In this embodiment, a U-shaped handle 30 is fixedly installed at the top center of the barrel 1 to facilitate carrying the hot fog machine by hand, and a pad 31 is fixedly installed at the bottom of the barrel 1 to facilitate supporting and placing the hot fog machine.

[0036] In this embodiment, a control panel 32 is fixedly installed on the right outer wall of the barrel 1. The control panel 32 is equipped with multiple control buttons. A power supply box 33 is fixedly installed at the bottom of the barrel 1. A rechargeable battery 34 is fixedly installed inside the power supply box 33. The booster pump 13, multiple first heating tubes 7, multiple second heating tubes 10, the control panel 32, and the rechargeable battery 34 are electrically connected. The rechargeable battery 34 is used to supply power to the booster pump 13, multiple first heating tubes 7, and multiple second heating tubes 10 respectively. The multiple control buttons can be used to control the start-up and operation of the booster pump 13, multiple first heating tubes 7, and multiple second heating tubes 10 respectively. It should be noted that the multiple first heating tubes 7 and multiple second heating tubes 10 are all temperature-adjustable electric heating tubes. Therefore, the heating temperature of the multiple first heating tubes 7 and multiple second heating tubes 10 can be adjusted by the multiple control buttons on the control panel 32. A charging port is provided on the front side wall of the power supply box 33. The charging port is electrically connected to the rechargeable battery 34 so as to charge the rechargeable battery 34 with a charger.

[0037] With the above structure, the thermal fogger provided in this application is easy to carry, improving ease of use. It also boasts high heating efficiency, allowing direct heating of the active pharmaceutical ingredient (API) without the use of solvents, causing it to evaporate and form a uniformly concentrated mist. This significantly saves resources, reduces environmental pollution, eliminates the need for dispensing, saves time and effort, and improves operational efficiency. In practical use, by unscrewing the end cap 12, the solid API is poured into the first heating chamber 2 through the feeding port 11. Then, the end cap 12 is screwed back into the feeding port 11. By energizing multiple first heating tubes 7 and multiple second heating tubes 10, the internal spaces of the first heating chamber 2 and the second heating chamber 3 can be heated. This process causes the solid raw material inside the first heating chamber 2 to melt and form a liquid raw material. The filter screen 5 intercepts and filters the solid raw material inside the first heating chamber 2, allowing the liquid raw material to flow through the filter holes in the filter screen 5 into the second heating chamber 3 for further heating. The solid raw material continues to melt and heat within the second heating chamber 3. By controlling the operation of the booster pump 13, boosted air enters the gas collection box 14 through the gas outlet pipe 15. The boosted air entering the gas collection box 14 then enters the serpentine heat-conducting pipe 17 through the first gas delivery pipe 16. Part of the heat from the multiple second heating pipes 10 is transferred to the wall of the serpentine heat-conducting pipe 17 via the heat-conducting plate 9, thereby... Heat is transferred to the pressurized air flowing within the serpentine heat pipe 17, heating the pressurized air. The heated air then passes through the second air supply pipe 18 and is finally ejected from multiple jet holes 19 from bottom to top. This accelerates the evaporation of the liquid active ingredient inside the second heating chamber 3, forming a smoke state. The smoke-like active ingredient then passes through the spray pipe 20 and is finally ejected from the nozzle 21. During the spraying of the smoke-like active ingredient, multiple arc-shaped blades 25 convert some of the kinetic energy of the pressurized air discharged from the outlet pipe 15 into mechanical energy, thereby controlling the drive shaft 22, the first horizontal shaft 23, multiple stirring blades 24, multiple arc-shaped blades 25, the connecting shaft 26, and the... The rotation of the two horizontal shafts 27 and multiple stirring blades 28, along with the rotation of multiple stirring blades 24, can disperse and stir the solid raw material inside the first heating chamber 2 evenly, making the solid raw material heat more evenly and accelerating the heating and melting efficiency of the solid raw material. The multiple stirring blades 28 can also stir the raw material in the smoke state inside the second heating chamber 3, mixing the volatilized smoke raw material evenly inside the second heating chamber 3, improving the uniformity of the concentration of the volatilized smoke raw material, and thus ensuring that the concentration of the smoke raw material sprayed from the nozzle 21 is uniform. After use, the booster air pump 13, multiple first heating tubes 7 and multiple second heating tubes 10 are turned off, and it can be carried away by hand.
