[0034] As shown in FIG1 , an embodiment of the present application provides a combined heating device, comprising: a heater body 1 and a mouthpiece 2 detachably mounted at one end of the heater body 1 ; the heater body 1 includes a first atomizing mechanism and at least one second atomizing mechanism; the mouthpiece 2 is provided with a mixing chamber 3 and a smoke outlet channel 4 therein; the smoke outlet channel 4 is in communication with the mixing chamber 3;

[0035] The first atomization mechanism includes a heating chamber 5, which is used to place solid smoking material and heat the solid smoking material to generate aerosol. One side of the heating chamber 5 is connected to the mixing chamber 3, and the other side of the heating chamber 5 is connected to the first air inlet channel 6;

[0036] The second atomization mechanism includes a smoke oil chamber 7 and an atomization chamber 8. An oil guide member 9 is provided in the atomization chamber 8. One end of the oil guide member 9 is communicated with the smoke oil chamber 7. One side of the atomization chamber 8 is connected to the mixing chamber 3, and the other side of the atomization chamber 8 is connected to the second air inlet channel 10.

[0037] The present embodiment provides a combined heating device, in which a solid smoking substance such as cigarettes and tobacco can be placed in the heating chamber 5 of the first atomizing mechanism, and the solid smoking substance such as cigarettes can be heated to generate aerosols, and the external gas enters the heating chamber 5 through the first air inlet channel 6, and brings the aerosol generated by the solid smoking substance into the mixing chamber 3, and the smoke oil chamber 7 of the second atomizing mechanism is used to place liquid smoking substances such as smoke oil, and the smoke oil in the smoke oil chamber 7 is transported to the atomizing chamber 8 through the oil guide 9, and is atomized into aerosol in the atomizing chamber 8, and the external gas enters the atomizing chamber 8 through the second air inlet channel 10, and brings the aerosol generated by the smoke oil into the mixing chamber 3, and the aerosol generated by the solid smoking substance and the aerosol generated by the smoke oil are mixed in the mixing chamber 3. The tobacco and the smoke are fully mixed and then inhaled by the smoker through the smoke outlet channel 4 from the mixing chamber 3. The combined heating device can heat the tobacco and the smoke-generating substance of the smoke oil at the same time, and can achieve full mixing of two or more aerosols through the mixing chamber 3, thereby improving the aroma of the inlet aerosol and maintaining the original aroma of tobacco, thereby diversifying the smoking taste and improving the smoking taste.

[0038] In this embodiment, the first atomizing mechanism and the second atomizing mechanism are preferably arranged in parallel, and one end of the first atomizing mechanism and the second atomizing mechanism are respectively close to the mouthpiece 2, the first air inlet channel 6 is located on the outside of the first atomizing mechanism, and the second air inlet channel 10 is located on the outside of the second atomizing mechanism. Specifically, the heater body 1 is cylindrical as a whole, and the first atomizing mechanism and the second atomizing mechanism are also cylindrical and arranged in parallel, so that the space utilization rate of the device is higher and it is convenient for the miniaturization of the device. A first air hole is provided on the outer wall of the heater body 1 near the first atomizing mechanism, and the first air hole is connected to the first air inlet channel 6. A second air hole is provided on the outer wall of the heater body 1 near the second atomizing mechanism, and the second air hole is connected to the second air inlet channel 10.

[0039] The mouthpiece 2 is detachably connected to the heater body 1 via a magnetic or snap-on connection. After removing the mouthpiece 2 from the heater body 1, a cigarette can be placed into the heating chamber 5 from the side of the heater body 1 near the mouthpiece 2, with the filter positioned near the mouthpiece 2. The second atomizer mechanism or the oil chamber 7 can be replaced from the side of the heater body 1 near the mouthpiece 2.

[0040] This embodiment optimizes the above technical solution. The inner diameter of the smoke outlet channel 4 gradually increases from one end near the heater body 1 to the other end. As the inner diameter of the smoke outlet channel 4 increases, the mixed aerosol smoke undergoes an expansion process from the small hole to the large hole in the gas outlet channel, which has the effect of lowering the smoke temperature and is beneficial for cooling the smoke.

[0041] Preferably, a central heating element 11 is provided in the middle of the heating chamber 5; alternatively, peripheral heating elements are provided on the side walls of the heating chamber 5. This embodiment preferably employs a central heating element 11, which has a pointed end for easy insertion into a cigarette or tobacco to heat the center of the cigarette or tobacco. Of course, peripheral heating elements (not shown in the accompanying drawings) can also be provided on the inner walls of the heating chamber 5 to heat the exterior of the cigarette or tobacco. Specifically, the peripheral heating elements can be heating resistors coated on the inner walls of the heating chamber 5 for heating.

[0042] To facilitate smooth and complete entry of the aerosol in the heating chamber 5 into the mixing chamber 3, the side of the heating chamber 5 away from the mouthpiece 2 is in communication with the first air inlet channel 6, and the side of the heating chamber 5 closer to the mouthpiece 2 is in communication with the mixing chamber 3. Specifically, external airflow enters the heating chamber 5 from the bottom and then enters the mixing chamber 3 from the top of the heating chamber 5, facilitating the entry of the aerosol in the heating chamber 5 into the mixing chamber 3.

[0043] This embodiment further illustrates the second atomization mechanism. The smoke oil chamber 7 is located at one end close to the cigarette holder 2, and the atomization chamber 8 is located at one end away from the cigarette holder 2. The side of the atomization chamber 8 away from the cigarette holder 2 is connected to the second air inlet channel 10. The smoke oil chamber 7 is located at one end close to the cigarette holder 2. After the cigarette holder 2 is removed, it is convenient to replace the smoke oil chamber 7 or replace the second atomization mechanism as a whole. The bottom of the atomization chamber 8 is connected to the second air inlet channel 10, so that the external airflow enters the atomization chamber 8 and carries out the aerosol in the atomization chamber 8. In this embodiment, preferably, an oil filling port is provided on the smoke oil chamber 7. The oil filling port is located on the side of the smoke oil chamber 7 close to the cigarette holder 2, so as to facilitate the injection of smoke oil into the smoke oil chamber 7. Different flavors of smoke oil can also be injected into the smoke oil chamber 7 through the oil filling port, so that the flavor of the smoke oil can be switched.

[0044] In order to prevent the smoke liquid from entering the second air inlet channel 10, the connection between the atomizing chamber 8 and the second air inlet channel 10 is sealed with an air-permeable and oil-impermeable material. The connection between the second air inlet channel 10 and the atomizing chamber 8 is sealed with an air-permeable and oil-impermeable semi-permeable material to prevent oil leakage.

[0045] Specifically, in this embodiment, an outflow channel 12 is provided in the middle of the heater body 1. The atomizing chamber 8 is connected to the outflow channel 12, and the outflow channel 12 is connected to the mixing chamber 3. The outflow channel 12 is provided at the central axis of the heater body 1. All the second atomizing mechanisms and the first atomizing mechanism are arranged around the outflow channel 12. The atomizing chambers 8 of all the second atomizing mechanisms are evenly connected to the outflow channel 12, so that the aerosol in the atomizing chamber 8 can enter the mixing chamber 3 through the outflow channel 12.

[0046] In this embodiment, an atomizing element 13 is preferably provided within the atomizing chamber 8. The atomizing element 13 is wrapped around or embedded within the oil guide 9. The atomizing element 13 is in contact with the oil guide 9 by being wrapped around or embedded within the atomizing element 13. When current passes through the atomizing element 13, the e-liquid on the oil guide 9 is heated and atomized. Specifically, the atomizing element 13 may be a resistance wire, a metal hot plate, or a ceramic heater.

[0047] In this embodiment, the heater body 1 also includes a power slot 14 and a control switch. The positive and negative poles of the power slot 14 are respectively connected to the heating circuit, and the heating circuit is respectively electrically connected to the atomizing element 13, the central heating element 11 or the peripheral heating element. The control switch is connected to the heating circuit, and the control switch is used to control the heating circuit to power on or off the atomizing element 13, the central heating element 11 or the peripheral heating element.

[0048] Specifically, the power supply slot 14 and the heating circuit are both located at the end of the heater body 1 away from the cigarette holder 2. The power supply slot 14 is used to install the battery. A control switch button is provided on the outside of the heater body 1. The control switch is connected to the heating circuit. The control switch can individually control the atomizing element 13, the central heating element 11 or the peripheral heating element to power on or off, thereby achieving the best combined heating effect.

[0049] Furthermore, the oil guide member 9 is made of one or more materials selected from the group consisting of a cotton core, a silicone core, a stainless steel mesh, glass fiber, porous ceramics, and ceramic fibers. The oil guide member 9 is made of one or more materials selected from the group consisting of a cotton core, a silicone core, a stainless steel mesh, glass fiber, porous ceramics, and ceramic fibers, and is shaped like a column, a rod, or a core. Liquid oil in the oil storage chamber is transported to the interior of the atomization chamber 8 through the capillary action of the oil guide member 9.
