In one embodiment, the accessory further comprises a hair care assembly comprising a hair care medium. The hair care medium is capable of flowing from the accessory to the outside, such that the fluid and the hair care medium can cooperate with the hair to style the hair. The position of the hair care assembly may be any as long as it is sufficient that the hair care medium can act on the hair from the accessory stream to the outside. The hair care medium may be applied to the hair separately from the fluid. Alternatively, the conditioning medium may be mixed with the fluid to co-act with the hair, in which case the mixing location of the conditioning medium and the fluid may be the inlet end of the body section, the interior of the body section, and/or the outlet end of the body section. In addition, the number of hair care components may be plural, and the plural hair care components may include the same or different hair care media. The hair care media can flow from the accessory to the outside at the same time or at intervals. Further, the hair care component can be arranged in the first body, and the cover plate is provided with a through hole, so that the hair care medium can flow to the outside conveniently. When the fluid is discharged from the fluid outlet, the fluid can form negative pressure near the fluid outlet, and the formed negative pressure can accelerate the discharge of the hair care medium from the hair care assembly due to the fact that the body section surrounds the hair care assembly, so that the mixing proportion of the hair care medium and the fluid is improved. In addition, the hair care component can be arranged in the second body, and through holes are formed in the surrounding body, so that hair care media can be conveniently discharged. The hair care medium is at least one of nutrient or anion. In this embodiment, the hair care medium is a nutrient. Particularly, but not limited to, essential oils or hair films. The hair care assembly is provided with a storage cavity for storing nutrients. The nutrients can be volatilized by themselves and discharged out of the hair care assembly. Further, the heated fluid can also accelerate evaporation of nutrients and exit the hair care assembly as it passes through the accessory.

In one embodiment, the hair care assembly comprises a generating unit for generating a hair care medium and/or assisting the flow of the hair care medium from the accessory to the outside. For example, in certain embodiments, the generating unit is a heating unit to accelerate the evaporation of nutrients. In another embodiment, the generating unit is for generating negative ions for hair care. The hair care assembly further comprises a power supply unit for supplying power to the generating unit. Further, the power supply unit may be a power supply. It will be appreciated that in other embodiments, the power supply unit may also be a wireless receiving coil. The wireless transmitting coil is arranged on the body, and wireless power transmission is realized through cooperation of the wireless transmitting coil and the wireless receiving coil so as to supply power for the generating unit.

In one embodiment, the inner wall of the reducing section is provided with sound absorbing material. Therefore, the frequency range of the sound waves which are effectively attenuated can be widened through the arrangement of the sound absorbing material, and the noise reduction effect is further improved. In this embodiment, the sound absorbing material may be sound absorbing cotton.

The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
