Description

[Detailed Description of the Invention] The present invention relates to a hair dryer nozzle.

FIG. 1 shows a conventional example in which a front-expanding flap-like nozzle body 2 is provided at the air outlet 1a of a hair dryer 1. By blowing air from the plurality of discharge holes 3 provided in the head, the air blowing area is expanded and the air is applied to a wide area of the hair. Therefore, finger-like protrusions 5 protruding forward from the front surface of the front wall 4 are used to lift the hair and blow air to create so-called soft hair. However, when the finger-like protrusions 5 come into contact with hair, the nozzle body 2 may be deformed by chemicals (cosmetics), become dirty, or easily attract dust, and the finger-like protrusions 5 may break due to falling. It has the disadvantage of being easy to wake up.

This invention was created in view of the above-mentioned drawbacks.
The purpose is to provide a hair dryer nozzle that can obtain a suitable wind pressure over a wide range and can direct the wind to the inside of the hair.

The present invention will be explained below with reference to examples. FIG. 2 shows a cross-sectional view of a hair dryer using one embodiment. 2 in the diagram is the air outlet 1 of the hair dryer 1
This nozzle body 2 has a front opening with a plurality of third annular ribs 6 concentric with the center coaxial with the air blowing direction. It is arranged as shown in the figure.
These annular ribs 6 are connected and fixed by a columnar lattice 7 provided in the shape of a cross at the front opening so that the upper and lower end surfaces thereof are parallel to the direction of air blowing.

Further, the distance between adjacent annular ribs 6 is gradually decreased from the outer circumference toward the center. Furthermore, the front and back positions of these annular ribs 6 are such that the center part is closer to the rear, that is, the hair dryer 1 side.
The surface enveloped by the front end surface is formed into an R curved surface.

FIG. 4 is an enlarged cross-sectional view showing the joint portion between the nozzle body 2 and the hair dryer 1. As shown in the figure, a groove 8 is provided on the inner peripheral surface of the air outlet 1a of the hair dryer 1. A protrusion 9 on the outer periphery of the rear end of the nozzle body 2 is fitted into the groove 8 and held by the spring elastic force of the nozzle body 2 made of, for example, synthetic resin. Although the annular rib 6 and the columnar lattice 7 are both integrally molded with the nozzle body 2, they may be formed separately. In FIG. 2, 10 is a motor, 11 is a fan, 12 is a heater, 13 is a hot/cold air switch and power switch, 14 is a rubber bushing, and 15 is a suction port.

Thus, the motor 10 is rotated and the fan 1 is rotated.
When you turn 1, the hair dryer 1 is removed from the suction port 15.
The air sucked into the interior is heated by the heater 12, and the heated air becomes hot air and blows into the air outlet 1.
It is sent into the nozzle body 2 from a. The sent hot air spreads along the inner wall of the nozzle body 2 as shown by the arrow in the figure and is discharged forward from the gap 6a between the annular ribs 6. Here, since the upper and lower end surfaces of the annular rib 6 are parallel to the air blowing direction, air can be blown efficiently without reducing the wind pressure, and furthermore, the dimension of the gap 6a becomes smaller gradually from the outer circumference toward the center. Therefore, the amount of hot air flowing from the gap 6a between the outer periphery and the center becomes equal. In this way, an appropriate amount of wind pressure can be maintained evenly on the outer periphery, and hot air can be evenly applied to the inside of the hair.
A so-called soft hair finish can be obtained. Further, since the front surface of the nozzle body 2 is formed as an R curved surface, the wind speed in front of the nozzle body 2 can be made uniform without expanding beyond the outer diameter of the nozzle body 2.

The present invention has a plurality of annular ribs arranged concentrically with respect to the center coaxial with the air blowing direction at predetermined intervals on the front opening of the front opening of the front-expanding latch-shaped nozzle body provided in the air outlet of the hair dryer. Because of this arrangement, it is possible to rectify the wind flow that spreads in the nozzle body in the gaps between the annular ribs and suppress the wind flow from spreading. Since the curved surface is concave toward the center, it is possible to suppress the above-mentioned range of wind diffusion to the size of the outer diameter of the nozzle body. It can blow hot air to the inside of the hair without using conventional finger-like protrusions, and has the effect of efficiently achieving a so-called soft hair finish. Since the openings are gradually enlarged from the opening to the outer periphery, the intervals between the annular ribs at the center opening are closer than the intervals between the annular ribs at the outer periphery. This causes the wind to flow toward the outer periphery where there is less resistance (larger spacing between the annular ribs). R that is concave toward the rear toward the center opening
Wind flows along the curved surface,
As a result, the effect is that uniform air can be blown from the entire surface of the nozzle body.
