Technical Field

[0001] This utility model relates to the technical field of hair care devices, and in particular to a hair dryer nozzle and a hair dryer. Background Technology

[0002] A hair dryer nozzle is an accessory used on a hair dryer. It is usually used with the handle of the hair dryer and is used to direct the airflow generated by the hair dryer to dry the user's wet hair.

[0003] Existing hair dryer nozzles typically consist of a nozzle housing and an internal air guide component. The nozzle housing has an air outlet, from which the air guide component directs the air generated by the hair dryer. When using this type of hair dryer, the nozzle needs to be pointed directly at the hair, and the direction of the dryer needs to be adjusted frequently. When drying different parts of the hair on the user's head, the angle that needs to be adjusted is relatively large, making it inconvenient for the user and requiring improvement. Utility Model Content

[0004] In order to make the hair dryer easier for users to operate when drying their hair, this utility model provides a hair dryer nozzle and a hair dryer.

The air guide tube has an air inlet at its bottom and an air outlet on its side wall. The air outlet includes a first outlet and a second outlet respectively disposed on both sides of the nozzle housing. The inner cavity of the nozzle housing is divided by the partition plate to form a first air outlet channel communicating with the first outlet and a second air outlet channel communicating with the second outlet, so that the air guide tube can be rotated to select different air output levels, including a left level, a middle level, and a right level.

[0007] By adopting the above technical solution, and by opening air outlets on both sides of the nozzle housing, and by allowing the air duct to rotate, the hair dryer nozzle has three speed settings, corresponding to the first outlet blowing air, the second outlet blowing air, and both air outlets blowing air simultaneously.

In addition, the arc-shaped adsorption surface has a large surface area, so that the heating surface is large and more hair can be adsorbed.

[0014] Optionally, a plane in which an air outlet direction of the air outlet is located is tangent to the arc-shaped adsorption surface.

[0015] By adopting the technical scheme, when the air is blown out from the air outlet, the air is not easy to collide on the arc-shaped adsorption surface and be blown away. In addition, the air can be attached to the arc-shaped adsorption surface by the Coanda effect, and a negative pressure is formed on the arc-shaped adsorption surface. When a user uses the hair dryer to blow hair and straighten the hair along the hair, the hair can be adsorbed on the arc-shaped adsorption surface under the action of the negative pressure, so that the hair is not easy to fly up.

[0016] Optionally, the hair dryer further comprises a knob head arranged at the top of the air nozzle shell and connected with the air guide pipe to drive the air guide pipe to rotate, and the knob head is provided with a selection locking assembly for locking the air guide pipe at different gears.

DETAILED DESCRIPTION

[0038] The utility model will be described in further detail below in combination with the drawings and examples.

[0039] The utility model discloses a hair dryer air nozzle.

[0040] Referring to Figure 1 and Figure 2 , the hair dryer air nozzle comprises an air nozzle housing 1, an air guide pipe 2, a partition plate 3 and a knob 4.

[0042] The suction portion 12 is cylindrical and has an arc-shaped suction surface 121. The circumferential angle of the arc-shaped suction surface 121 is greater than 100°, and in this embodiment, is 120°. The first outlet 112 and the second outlet 113 are located at both ends of the arc-shaped suction surface 121.

[0043] Referring to Figures 1 to 3The air duct 2 rotates in the inner cavity of the air nozzle shell 1 and is coaxial with the adsorption part 12. The air duct 2 penetrates the bottom of the air nozzle shell 1, and the bottom of the air duct 2 is provided with an air inlet 21 for air to enter. The side of the air duct 2 is provided with an air outlet 22 for air entering from the air inlet 21 to blow out. The air outlet 22 is provided along the length direction of the air duct 2, and the shape of the air outlet 22 can be a long strip or a plurality of holes spaced apart, and the shape of the hole is arbitrary as long as it can blow out air.
