It should be understood that those skilled in the art will recognize that this application can be made without using these specific details. In other instances, well-known structures and processes are not described in detail to avoid obscuring the description of this application with unnecessary detail. Therefore, this application is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0025] like Figures 1 to 4 As shown, on the one hand, this application provides an air duct structure 1, which includes a main air duct 10, an aromatherapy air duct 20 and an aromatherapy chamber 30. When realizing the aromatherapy function, no additional power is required, which significantly reduces the operating power consumption of the air conditioner 100 and has a better energy-saving effect.

[0026] Here, the air duct structure 1 can be applied to air supply equipment such as air conditioner 100, and the main air duct 10 can be the main air duct structure 1 of the air supply equipment to realize the functions of return air and air supply. When the air duct structure 1 is applied to air conditioner 100, the main air duct 10 can be the main heat exchange air duct of air conditioner 100, and functional components such as fan 2 and heat exchanger 3 can be installed in the main air duct 10.

[0027] The aromatherapy duct 20 has an air inlet contraction section 21, a throat 22, and an air outlet expansion section 23 connected in sequence. One end of the air inlet contraction section 21 opens into the side wall of the main air duct 10 to form an air inlet end 211, and one end of the air outlet expansion section 23 opens into the side wall of the main air duct 10 to form an air outlet end 231. In this way, the air inlet end 211 and the air outlet end 231 of the aromatherapy duct 20 are respectively connected to the main air duct 10. The gas in the main air duct 10 can enter the aromatherapy duct 20 from the air inlet end 211, flow through the air inlet contraction section 21, the throat 22, and the air outlet expansion section 23 in sequence, and then flow back into the main air duct 10 from the air outlet end 231. The air inlet contraction section 21 gradually contracts from the air inlet end 211 to the throat 22, that is, the flow cross-sectional area of ​​the air inlet contraction section 21 gradually decreases from the air inlet end 211 to the throat 22; the air outlet expansion section 23 gradually expands from the throat 22 to the air outlet end 231, that is, the flow cross-sectional area of ​​the air outlet expansion section 23 gradually increases from the throat 22 to the air outlet end 231.

[0028] The aromatherapy chamber 30 has an aromatherapy hole 31 opening into the side wall of the throat 22, so that the aromatherapy chamber 30 and the throat 22 are connected through the aromatherapy hole 31. The aromatherapy chamber 30 can store aromatherapy substances, such as essential oils and other substances that can produce aromatherapy gases.

[0029] When aromatherapy is needed, a portion of the airflow from the main air duct 10 can enter the aromatherapy duct 20 through the air inlet 211, and then pass through the air inlet contraction section 21 before entering the throat 22. During this process, due to the connection structure of the air inlet contraction section 21, the throat 22, and the air outlet expansion section 23, a negative pressure is formed in the throat 22. This negative pressure allows the aromatherapy gas generated in the aromatherapy chamber 30 to enter the throat 22 through the aromatherapy hole 31, and then mix with the airflow from the throat 22 before passing through the air outlet expansion section 23 and the air outlet 231 and converging into the main air duct 10. This allows the aromatherapy gas to be released into the indoor environment along with the airflow from the main air duct 10, thus achieving the aromatherapy function.

[0030] Compared with related technologies, the air duct structure 1 provided in this application embodiment does not require an additional power source. Instead, it uses the structure of the aromatherapy air duct 20 to release the aromatherapy gas in the aromatherapy chamber 30 into the throat 22 and the main air duct 10 in sequence. When realizing the aromatherapy function, no additional power is consumed, which significantly reduces the operating power consumption of the air conditioner 100 and achieves better energy-saving effect.

[0031] In some embodiments, the air duct structure 1 may include an air valve 40. The air valve 40 is disposed at the air inlet end 211 and is used to open and close the aromatherapy air duct 20. When aromatherapy is needed, the air valve 40 can be controlled to open, allowing a portion of the airflow from the main air duct 10 to enter the aromatherapy air duct 20 as described above, creating a negative pressure at the throat 22, thereby releasing the aromatherapy gas generated in the aromatherapy chamber 30 using the negative pressure. When aromatherapy is not needed, the air valve 40 can be controlled to close, preventing the airflow from the main air duct 10 from entering the aromatherapy air duct 20, thereby preventing the formation of negative pressure at the throat 22 and thus preventing the release of the aromatherapy gas generated in the aromatherapy chamber 30.

[0032] In some embodiments, the shrinkage ratio of the air inlet shrinkage section 21 can be set to greater than or equal to 1.5. Within this shrinkage ratio range, when a portion of the airflow from the main air duct 10 enters the aromatherapy duct 20 as described above, the aromatherapy duct 20 easily forms a negative pressure at the throat 22, thereby allowing for the rapid and reliable release of the aromatherapy gas from the aromatherapy chamber 30.

[0033] In some embodiments, the contraction ratio of the air outlet expansion section 23 can be set to be greater than or equal to 1.3. Within this contraction ratio range, when a portion of the air outlet airflow in the main air duct 10 enters the aromatherapy air duct 20 as described above, the aromatherapy air duct 20 easily forms a negative pressure at the throat 22, thereby enabling the rapid and reliable release of the aromatherapy gas in the aromatherapy chamber 30.

[0034] In some embodiments, the throat 22 has a throat body 221 and an annular cavity 222 surrounding the throat body 221, with the aromatherapy hole 31 opening onto the outer wall of the annular cavity 222. The sidewalls of the air inlet constriction section 21 and the air outlet expansion section 23 are fitted into the middle region of the throat body 221 to form an annular hole 223, which communicates with the annular cavity 222. Here, when part of the airflow in the main air duct 10 enters the aromatherapy air duct 20 as described above, the airflow flows sequentially through the air inlet contraction section 21, the throat body 221, and the air outlet expansion section 23, making the pressure in the throat body 221 less than that in the annular cavity 222, and the pressure in the annular cavity 222 less than that in the aromatherapy cavity 30. This creates a first negative pressure in the annular cavity 222 that is lower than the pressure in the aromatherapy cavity 30, and a second negative pressure in the throat body 221 that is lower than the pressure in the annular cavity 222. The aromatherapy gas in the aromatherapy cavity 30 is released into the annular cavity 222 by the first negative pressure, and then the aromatherapy gas in the annular cavity 222 is released into the throat body 221 through the annular hole 223 by the second negative pressure, thus achieving a rapid and reliable release of the aromatherapy gas in the aromatherapy cavity 30.

[0035] In some embodiments, the ratio of the depth of the annular hole 223 to the length of the throat body 221 is greater than or equal to 1 / 4. Here, the depth direction of the annular hole 223 is parallel to the length direction of the throat body 221. Within this ratio range, a negative pressure can be better formed between the annular cavity 222 and the throat body 221, thereby enabling the rapid and reliable release of aromatherapy gas from the aromatherapy chamber 30.

[0036] In some embodiments, the air inlet 211 and the air outlet 231 can be arranged sequentially at intervals along the gas flow direction of the main air duct 10. In other words, the air inlet 211 is located upstream of the air outlet 231 along the gas flow direction of the main air duct 10, so that the gas flow sequence in the aromatherapy air duct 20 is roughly consistent with the gas flow sequence in the main air duct 10, avoiding airflow conflict or turbulence.

[0037] In some examples, the main air duct 10 may have an air outlet 11, with the air outlet 231 located adjacent to the air outlet 11. In this way, after the airflow containing aromatherapy gas is released from the air outlet 231 into the main air duct 10, it can be directly released into the indoor environment from the adjacent air outlet 11, effectively increasing the aromatherapy effect.

[0038] In some embodiments, the ratio of the aperture of the aroma diffuser 31 to the length of the sidewall of the throat 22 can be set to 20% to 30%. Within this ratio range, the negative pressure formation effect of the throat 22 and the gas flow rate of the aroma diffuser 31 can be better guaranteed, thereby achieving the aroma diffuser function better.

[0039] In some embodiments, the end of the aromatherapy chamber 30 away from the aromatherapy hole 31 may also be provided with a vent 32. By providing the vent 32, the aromatherapy gas in the aromatherapy chamber 30 can be further forced to be released from the aromatherapy hole 31 to the throat 22.

[0040] In some embodiments, the aromatherapy cavity 30 can be a conical cavity, with the aromatherapy hole 31 located at the bottom of the conical cavity. The type of conical cavity can be determined according to actual needs, and can be a polygonal conical cavity, a semi-cylindrical conical cavity, etc., which is not limited in this application embodiment. In the conical cavity construction, the cross-sectional area of ​​the aromatherapy cavity 30 decreases from the top to the bottom, forming a shrinkage structure, thereby better ensuring that the aromatherapy gas in the aromatherapy cavity 30 is released from the aromatherapy hole 31.

[0041] On the other hand, this application embodiment provides an air conditioner 100, which includes the air duct structure 1 provided in any of the above embodiments. The type of air conditioner 100 can be determined according to actual needs, and may be, for example, a wall-mounted air conditioner, a cabinet air conditioner, a window air conditioner, a ceiling-mounted air conditioner, etc., and this application embodiment does not limit this. The air conditioner 100 provided in this application embodiment has the above-mentioned air duct structure 1, and does not require additional power consumption when realizing the aromatherapy function, significantly reducing the operating power consumption of the air conditioner 100 and having a better energy-saving effect.

[0042] In some embodiments, the air conditioner 100 may include a fan 2 and a heat exchanger 3, which are respectively disposed in the main air duct 10.

[0043] The duct structure and air conditioner provided in the embodiments of this application have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
