[0001] This invention belongs to the field of hair dryer technology, specifically relating to an air outlet structure and a vertical hair dryer. Background Technology

[0002] Currently available upright high-speed hair dryers typically use a motor-driven fan that rotates at high speed to concentrate airflow through a heating element, which is then output to a fixed outlet for rapid hair drying. The problem with this type of airflow design is that the outlet direction is fixed, making it impossible to change the direction of the airflow and negatively impacting the user experience. Furthermore, the outlet structure is prone to rapid heating due to hot air, making it inconvenient for users to touch or adjust its position, further affecting the user experience. These features require further improvement. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a wind structure and a vertical hair dryer.

[0011] Furthermore, the aromatherapy holder includes an aromatherapy holder body and a bottom cover. The aromatherapy holder body is provided with an aromatherapy cavity extending upward from its bottom surface for placing aromatherapy tablets. The bottom cover is detachably disposed at the bottom of the aromatherapy holder body, and its opposite side to the aromatherapy cavity is provided with multiple support parts for supporting the aromatherapy tablets. The aroma outlet is disposed on the bottom cover and communicates with the aromatherapy cavity.

[0012] Furthermore, it also includes a negative ion generator, which is installed in the main body housing and includes a negative ion generating head and a negative ion wire. The first end of the negative ion wire is electrically connected to the negative ion generating head, and the second end extends to the bottom of the air outlet cavity and is arranged close to multiple air outlets.

[0013] Furthermore, the side of the air outlet near the air outlet is the air outlet surface. The air outlet includes a first air outlet housing, a second air outlet housing, and an air outlet base. The upper end of the first air outlet housing is connected to the lower end of the air inlet. The second air outlet housing is disposed at the lower end of the first air outlet housing. The air outlet base is disposed between the first air outlet housing and the second air outlet housing. The second end of the negative ion line is disposed near the air outlet surface. The heat insulation cavity is disposed between the first air outlet housing and the second air outlet housing. The air outlet cavity is disposed in the air outlet base. A plurality of air outlets are spaced apart at the bottom of the air outlet base. A plurality of air outlet holes are spaced apart at the bottom of the second air outlet housing. The plurality of air outlet holes are respectively opposite to the plurality of air outlets.

[0014] Furthermore, the bottom surface of the air outlet is provided with multiple positioning blocks for fixing the negative ion wires at intervals.

[0015] Furthermore, the air inlet includes an air inlet outer shell and an air inlet inner cylinder disposed within the air inlet outer shell. The air inlet cavity is disposed within the air inlet inner cylinder. The air inlet outer shell is connected to the first air outlet shell. A connecting portion is provided at the upper end of the air outlet seat. The lower end of the air inlet inner cylinder extends into the first air outlet shell and connects with the connecting portion. A heat insulation chamber is formed between the outer wall of the air inlet inner cylinder and the inner wall of the air inlet outer shell. The negative ion generator head is fixed to the outer surface of the air inlet inner cylinder, and the second end of the negative ion line extends along the air inlet inner cylinder to a position close to the air outlet surface.

The support rod is an adjustable-height lifting rod to allow the air outlet to blow air to the user from all directions at different heights and angles.

[0017] As can be seen from the above description of the present invention, compared with the prior art, the beneficial effects of the present invention are as follows: By defining the composition of the air outlet structure and setting an air guide component in conjunction with multiple air outlets, the air entering the air outlet cavity can be evenly distributed to multiple air outlets under the action of the air guide component, increasing the area of ​​the head receiving air, and increasing the heat insulation cavity surrounding the air outlet cavity and multiple air outlets, isolating the heat of the air outlet cavity and multiple air outlets from the outer surface of the main body shell, reducing the heat transfer from the air outlet cavity or air outlet to the outer surface of the main body shell, slowing down the rate of temperature rise of the outer surface of the main body shell, and making it convenient for users to touch and adjust the air outlet structure during use;

[0018] The structure of the main housing is further defined to facilitate the installation of the negative ion generator. The negative ion wire is located below the air outlet cavity, and the negative ion generator head is located on the outer surface of the air inlet cylinder, reducing its contact with hot air and increasing the service life of the negative ion generator head. The farther the negative ion generation location is from the air outlet, the lower the concentration of negative ions blown out from the air outlet. In this invention, the negative ion wire extends along the air inlet cylinder to the air outlet and is limited below the air outlet cavity, so that one end of the negative ion wire is placed as close as possible to the relative air outlet, allowing the air blown out from the air outlet to contain a higher concentration of negative ions. When blown onto the hair, it can eliminate static electricity and prevent tangling, improving the user experience. Attached Figure Description

One end of the negative ion line 52 extends below the air outlet cavity 35, and the negative ion generator head 51 is set on the outer surface of the air inlet inner cylinder, reducing the contact between the negative ion generator head 51 and the hot air, and increasing the service life of the negative ion generator head 51. The farther the location from the air outlet 36 is where the negative ions are finally emitted, the lower the concentration of negative ions blown out by the air outlet 36. In this invention, the negative ion wire 52 extends along the air inlet cylinder 412 into the air outlet 42 and is limited below the air outlet cavity 35, so that one end of the negative ion wire 52 is set as close as possible to the relative air outlet 36, so that the air blown out by the air outlet 36 contains a higher concentration of negative ions. When blown onto the hair, it can eliminate static electricity and prevent tangling, thus improving the user experience.
