The fluid is a non-heated fluid or a heated fluid, and the corresponding hair drying device may be provided with a fan assembly, a heating assembly and a control panel for controlling the fan assembly and the heating assembly, the fan assembly and the heating assembly being controlled by the control panel to produce the corresponding fluid.

Further, the housing 10 is located on the first channel. The housing 10 is circumferentially provided with a second passage 30 communicating with the first passage. The location of the housing 10 in the first passage does not affect the connectivity of the first passage, i.e. the connectivity of the first passage is ensured by the second passage 30, ensuring that the fluid flows to the corresponding location in the first passage.

Further, the housing 10 includes a body 100 and a cover 200 detachably connected. The body 100 is formed with a groove and a third channel 110 for communicating the first channel and the groove. The cover 200 has an angle greater than 0 ° and less than 180 ° with the fluid flow direction. The cover body 200 is used for covering the groove, and the champignon carrier 20 is accommodated in the groove. The body 100 is detachable from the cover 200, so that the fragrance carrier 20 in the groove can be replaced conveniently, and the fragrance carrier 20 with different smells can be selected for replacement according to personal preference when the hair drying device is used. The fragrance carrier 20 diffuses the smell thereof into the first channel through the third channel 110, and an included angle larger than 0 degree and smaller than 180 degrees is formed between the cover body 200 and the fluid flowing direction, so that only one side of the fragrance carrier 20 is communicated with the first channel through the third channel 110, and the other side is shielded by the cover body 200, so that the fluid is prevented from scouring the fragrance carrier 20, and the rapid consumption of the fragrance carrier 20 is avoided.

Specifically, the fluid flows from one side of the cover body 200 to the housing 10, flows to the second channel 30 located in the circumferential direction of the housing 10 after being shielded by the cover body 200, further continues to flow to the corresponding position through the housing 10, and carries the fragrance diffused into the first channel; alternatively, the fluid flows from one side of the body 100 to the housing 10, meets the fragrance diffused into the first channel and carries it straight to the body 100, meets the body 100 and then flows to the second channel 30 located at the periphery of the housing 10, and then continues to flow to the corresponding position through the housing 10. In the two forms, the fluid does not pass through the aroma carrier 20, and the aroma carrier 20 and the fluid are only in contact with each other at the third channel 110, so that the contact surface is small, the too fast consumption of the aroma carrier 20 is effectively avoided, and the service life of the aroma carrier 20 is prolonged.

As shown in fig. 2, a protrusion 120 is formed on a side of the body 100 away from the cover 200 to form a groove, and the third channel 110 is formed on the protrusion 120. In the present embodiment, the number of the third passages 110 is plural and is uniformly formed on the groove bottom and/or the side wall of the protrusion 120. The protrusions 120 are preferably spherical protrusions 120 that help to facilitate fluid flow to the second channel 30 after the fluid encounters the body 100, reducing the obstruction of the fluid by the third channel 110. Further, the aroma carrier 20 is abutted between the protrusion 120 and the cover body 200 through the cover body 200. Fix fragrance carrier 20 in the recess through lid 200, avoid fragrance carrier 20 to remove relative casing 10 in hair drying device's use, produce to rattle and influence and use experience. The aroma carrier 20 is abutted between the protrusion 120 and the cover body 200 through the cover body 200, so that the aroma carrier 20 is abutted on one side of the third channel 110 located in the groove, and the aroma carrier 20 is closer to the first channel to facilitate the diffusion of aroma. Meanwhile, the fragrance carrier 20 is abutted between the protrusion 120 and the cover 200 through the cover 200, so that the overall rigidity of the casing 10 and the fragrance carrier 20 can be increased, and the fragrance carrier becomes an integral body to resist the impact of fluid.

Further, the aroma carrier 20 is a wood block impregnated with fragrance or a container containing fragrance, the container having a through hole for volatilization of fragrance. Specifically, the wood block is matched with the groove and provides a certain pressure through the cover body 200, so that the wood block can be abutted between the protrusion 120 and the cover body 200. The wood pieces may be impregnated with a fragrance, and when the fragrance of the wood pieces is depleted or a different fragrance is desired to be replaced, the wood pieces may be re-impregnated with the fragrance to obtain the same or a different fragrance. The same is true. By replacing different wood blocks, when the hair drying device is used, different fragrances can be replaced quickly. The fragrance contained in the container may also be replaced when the fragrance is depleted or when a different fragrance is exchanged. The same is true. By replacing different containers, the replacement of different fragrances is accelerated when the hair drying device is used.

The cover 200 is detachably connected to the main body 100 by means of clamping, screwing or magnetic attraction. As shown in fig. 2 and 3, the body 100 has an annular groove 130 for engaging with the cover 200.
