[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present invention and its application or use. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative work are within the scope of protection of the present invention.

[0035] like Figures 1 to 3 As shown, an embodiment of the present invention provides an aromatherapy component, including a shell 10, an aromatherapy box 20, a transmission part 30 and a driving part 40. The two sides of the shell 10 are respectively the outer side and the inner side. One end of the transmission part 30 is connected to the aromatherapy box 20, and the other end of the transmission part 30 is connected to the driving part 40. During operation, the driving part 40 drives one end of the transmission part 30 to rise or fall, so that the transmission part 30 drives the aromatherapy box 20 to rise from the outer side to the inner side for use, or drives the aromatherapy box 20 to fall from the inner side to the outer side for replacement.

[0036] In this solution, the housing 10, aromatherapy cartridge 20, transmission unit 30, and drive unit 40 work together to allow the aromatherapy cartridge 20 to be raised and lowered. This allows the cartridge 20 to be raised to a higher position for use and lowered to a position easily accessible for replacement. This solution eliminates the need for users to climb to a higher position to replace the aromatherapy cartridge 20, improving operational convenience and safety, and enhancing the user experience.

[0037] The drive unit 40 is located inside the housing 10. The transmission unit 30 includes a rotating shaft 31 and a flexible transmission belt 32. The drive unit 40 drives the rotating shaft 31 to rotate. The transmission belt 32 is wound around the rotating shaft 31. The lower end of the transmission belt 32 is connected to the aromatherapy box 20. The transmission belt 32 is unwound or wound to move the aromatherapy box 20 up and down. The winding and unwinding of the transmission belt 32 thus achieves the ascent and descent of the aromatherapy box 20. This structure allows for a large travel range for the aromatherapy box 20 while minimizing the space occupied by the transmission unit 30.

[0038] Optionally, the rotating shaft 31 is provided with two spaced stop rings, and the transmission belt 32 is located between the two stop rings. In this way, the transmission belt 32 can be limited by the two stop rings.

[0039] In this solution, the lower end of the transmission belt 32 is detachably connected to the aromatherapy box 20, so that the aromatherapy box 20 can be easily replaced.

[0040] The aromatherapy box 20 is provided with adhesive strips 21 on opposite sides, and the lower end of the transmission belt 32 includes two connecting strips, which are respectively bonded to the two adhesive strips 21. The bonding method does not require the use of tools and is convenient for user operation.

[0041] In this embodiment, the housing 10 has a notch 11 for the aromatherapy box 20 to pass through. When the aromatherapy box 20 is located inside, the notch 11 is blocked by the aromatherapy box 20, and the surface of the aromatherapy box 20 is flush with the outer surface of the housing 10. This ensures an aesthetically pleasing appearance and prevents mosquitoes from entering.

[0042] Furthermore, the aromatherapy component also includes a positioning structure 50, which is located inside the housing 10 and cooperates with the aromatherapy box 20 to limit the position of the aromatherapy box 20 inside. This ensures that the aromatherapy box 20 is accurately positioned inside to ensure the use effect.

[0043] Specifically, the positioning structure 50 includes a first positioning post 51 and a first magnetic member 52 disposed on the first positioning post 51. The first positioning post 51 is connected to the housing 10, and the first magnetic member 52 and the aromatherapy box 20 are detachably attracted. Through magnetic attraction, when the aromatherapy box 20 is sufficiently close to the first magnetic member 52, it can be automatically attracted and positioned, and can be easily separated.

[0044] like Figure 2 As shown, the first magnetic member 52 is located in the lifting path of the aromatherapy box 20. The first magnetic member 52 is an electromagnet whose magnetism can be changed to attract or repel the aromatherapy box 20. By controlling the magnetic attraction of the electromagnet, the aromatherapy box 20 can be attracted or repelled, thereby achieving installation and removal of the aromatherapy box 20.

[0045] like Figure 3 As shown, the aromatherapy box 20 includes a box body 22, a second positioning column 23, and a second magnetic member 24 connected in sequence. The second magnetic member 24 and the first magnetic member 52 can be detachably attracted to each other. In this way, the aromatherapy box 20 and the positioning structure 50 are positioned and matched by the cooperation of the two magnetic members.

[0046] The box body 22 has a plurality of ventilation holes, and aromatherapy materials are placed in the box body 22. There are two first positioning posts 51, first magnetic members 52, second positioning posts 23, and second magnetic members 24, which can improve the reliability of the connection and the accuracy of the positioning.

[0047] Optionally, the first positioning post 51 has a tapered guide groove, and the first magnetic member 52 is located at the bottom of the guide groove, i.e., the end with the smaller diameter. During attraction, the second positioning post 23 and the second magnetic member 24 correspond to the guide groove and move toward the interior of the guide groove under the guidance of the guide groove, so that the second magnetic member 24 and the first magnetic member 52 are attracted to each other, achieving precise positioning.

[0048] Optionally, the housing 10 is further provided with a limiting frame having a limiting hole. The transmission belt 32 passes through the limiting hole to limit the position of the transmission belt 32 to prevent shaking and ensure that the aromatherapy box 20 accurately corresponds to the notch 11 of the housing 10. Furthermore, a roller is provided on the inner wall of the limiting hole, and the roller and the transmission belt 32 are in rolling engagement to reduce friction.

[0049] like Figures 4 to 6 As shown, the present invention also provides an air conditioner, which includes a panel body 60 and the above-mentioned aromatherapy component, the panel body 60 has an air outlet 61, the panel body 60 forms a shell 10 of the aromatherapy component, and the aromatherapy box 20 of the aromatherapy component is located on one side inside the air outlet 61 to emit fragrance through the air outlet 61.

[0050] In this solution, the panel 60, aromatherapy box 20, transmission unit 30, and drive unit 40 cooperate to enable the aromatherapy box 20 to be raised and lowered. This allows the aromatherapy box 20 to be raised to a higher position for use and lowered to a position easily accessible for replacement. This solution eliminates the need for users to climb to replace the aromatherapy box 20, improving operational convenience and safety, and enhancing the user experience.

[0051] Specifically, the air conditioner further includes a bottom shell 70, which is connected to the panel body 60. An air duct cavity is formed between the side walls of the bottom shell 70 and the panel body 60, and the air duct cavity is connected to the air outlet 61. An interlayer cavity 71 is formed between the bottom wall of the bottom shell 70 and the bottom wall of the panel body 60. The aromatherapy box 20, transmission unit 30, and drive unit 40 of the aromatherapy component are located within the interlayer cavity 71. The side walls of the bottom shell 70 have through holes 72, and the interlayer cavity 71 is connected to the air outlet 61 through the through holes 72. In this way, the existing interlayer cavity 71 between the bottom wall of the bottom shell 70 and the bottom wall of the panel body 60 can be used to accommodate the aromatherapy box 20, transmission unit 30, and drive unit 40 of the aromatherapy component, without taking up additional space. A plurality of through holes 72 can be provided to allow the fragrance generated by the aromatherapy box 20 to be dispersed to the air outlet 61 and blown out with the wind.

[0052] The present invention also provides a method for replacing an aromatherapy cartridge. The method is applied to the aforementioned air conditioner. The air conditioner's aromatherapy component includes a positioning structure 50, which is detachably connected to the aromatherapy cartridge 20. The method includes: disconnecting the positioning structure 50 from the aromatherapy cartridge 20 located within the panel body 60; lowering the lower end of the transmission unit 30 to drive the aromatherapy cartridge 20 to a predetermined position below the panel body 60; replacing the aromatherapy cartridge 20 at the predetermined position; raising the lower end of the transmission unit 30 to drive the replaced aromatherapy cartridge 20 into the panel body 60; and connecting the positioning structure 50 to the replaced aromatherapy cartridge 20 to define the position of the aromatherapy cartridge 20. In this manner, the aromatherapy cartridge 20 can be replaced by raising and lowering it, eliminating the need for the user to perform operations from a height, thereby improving user experience and safety.

[0053] Specifically, the positioning structure 50 includes an electromagnet, wherein, by changing the magnetism of the electromagnet, the electromagnet and the aromatherapy box 20 located in the panel body 60 are repelled from each other to disconnect, or the electromagnet and the aromatherapy box 20 are attracted to each other to connect. In this way, by changing the magnetism of the electromagnet, the aromatherapy box 20 can be easily replaced. In a specific embodiment, the operation process is as follows Figure 7 shown.
