After the liquid in the second installation tank 46 flows into the main channel 47 through each branch channel 48, the liquid in the main channel 47 flows into the filter cotton interlayer 292 through the siphon effect of the liquid. The hot air in the activated carbon interlayer 291 and the filter cotton interlayer 292 are filtered to remove odors. The moist filter cotton interlayer 292 can also be used to humidify the hot air to prevent the gas discharged from each ventilation hole 25 from being too dry, thereby further improving the user's comfort.

[0027] An operating chamber 49 is provided on the rear side of the fireplace body 1. The operating chamber 49 communicates with the exhaust chamber 8. The opening of the operating chamber 49 is covered with a sealing plate 50. A first mounting plate 51 is installed at the opening of the exhaust chamber 8 away from the exhaust hood 20. The first mounting plate 51 is provided with a first mounting part that is inserted into the exhaust chamber 8. The first mounting part is provided with a sealing cover 53. The sealing cover 53 covers the corresponding placement cavity 17. The bottom surface of the aroma tray 9 abuts against the top surface of the sealing cover 53. The first mounting plate 51 is set on the sealing cover 53 to prevent the aroma stone 18 in the receiving cavity 57 that has not been switched to the fourth cavity from evaporating.

[0028] The inner wall of the operating cavity 49 has a receiving cavity 57 for accommodating the rotary drive device 10. The receiving cavity 57 communicates with the rotating hole 16. A synchronous transmission assembly 58 is provided between the movable part of the rotary drive device 10 and the lower end of the first rotating shaft 15. The synchronous transmission assembly 58 includes two synchronous pulleys and a transmission belt body sleeved on the two synchronous pulleys. The inner side wall of the transmission belt body and the outer side wall of the synchronous pulleys can be a meshing rack structure. A second rotating shaft 59 is rotatably connected inside the receiving cavity 57. The two synchronous pulleys are respectively located at the lower ends of the first rotating shaft 15 and the second rotating shaft 59. The movable part of the 10 is detachably connected to the upper end of the second rotating shaft 59. The opening cover of the accommodating cavity 57 is provided with a second mounting plate 52. The second mounting plate 52 is provided with a second mounting part that is inserted into the operating cavity 49. The rotary drive device 10 is provided on the upper part of the second mounting part. An movable space is formed between the upper part of the second mounting part and the inner wall of the accommodating cavity 57. The movable part of the rotary drive device 10 and the opposite end of the second rotating shaft 59 are in a concave-convex fit so that the second rotating shaft 59 rotates with the mounting part. The movable space allows the second mounting plate 52 to move upward so that the mounting part and the second rotating shaft 59 can be separated.

[0029] The user can detach the sealing plate 50 to open the operating chamber 49. The first mounting plate 51 and the second mounting plate 52 are both bolted to the inner wall of the operating chamber 49, and can disassemble and maintain the internal components of the fireplace body 1.

[0030] The blower position adjustment device includes a connecting plate 12, a first drive shaft 13 and a second drive shaft 14. The first drive shaft 13 and the second drive shaft 14 are rotatably connected to the connecting plate 12 in parallel and at intervals. The opposite ends of the first drive shaft 13 and the first rotating shaft 15 are respectively provided with two meshing bevel gears 42. Both the first drive shaft 13 and the second drive shaft 14 are provided with spur gears 43, which mesh with each other.

[0031] The exhaust hood 20 is provided with several air blowing areas. The inner side wall of the exhaust hood 20 is provided with guide cavities 45 corresponding to the air blowing areas. The inner cavity of the guide cavity 45 is conical. The larger opening of the guide cavity 45 corresponds to the exhaust cavity 8, and the smaller opening of the guide cavity 45 corresponds to each ventilation hole 25 of the air blowing area, so as to guide the hot air in the exhaust cavity 8 to be discharged from each ventilation hole 25 of the corresponding air blowing area.

[0032] When the user activates the rotary drive device 10 to switch the position of the aroma diffuser disc 9 as needed, the first rotating shaft 15 drives the first transmission shaft 13 to rotate under the meshing of the two bevel gears 42. Under the cooperation of the first spur gear 43 and the second spur gear 43, the first transmission shaft 13 drives the second transmission shaft 14 to rotate to drive the moving disc 44 to rotate. The blowing device 11 rotates circumferentially around the second transmission shaft 14 with the moving disc 44 until the pre-selected placement cavity 17 moves to the top opening of the combustion chamber 2. The blowing device 11 then corresponds to each ventilation hole 25 of the corresponding blowing area, so that the blowing device 11 adjusts the blowing height synchronously when switching the aroma diffuser disc 9. The aroma of different types of aroma stones 18 has different volatilization levels. When switching aromas, the fireplace can adjust the blowing height of the blowing device 11 according to the type of aroma stone 18 in the accommodating cavity 57 corresponding to the combustion chamber 2, so that the user can adjust the volatilization of the aroma according to different needs.

[0033] The first drive shaft 13 is located below the second drive shaft 14, so that the blower 11 and the moving plate 44 are both at a height difference with the first rotating shaft 15, thus avoiding interference between them.

[0034] Both the first drive shaft 13 and the second drive shaft 14 pass through the first mounting plate 51 and rotate. An observation groove 54 is provided on the outer wall of the first mounting plate 51. A first indicator 55 is provided at the end of the first drive shaft 13 that passes through the first mounting plate 51, and a second indicator 56 is provided at the end of the second drive shaft 14 that passes through the first mounting plate 51. The first indicator 55 and the second indicator 56 are offset and both move within the observation groove 54. When the user opens the operating cavity 49, the rotational movement of the first indicator 55 and the second indicator 56 within the observation groove 54 allows the user to determine whether the air blowing position adjustment device is operating normally.

[0035] Of course, the above are just typical examples of the present invention. In addition, the present invention may have many other specific embodiments. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed by the present invention.
