BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a nozzle for a hair dryer which can blow or blow hot air or cold air to set or dry hair.

[0002]

2. Description of the Related Art FIG. 5 shows a conventional hair dryer. The dryer body 3 has a cylindrical portion 3a.
And a handle portion 3b, and inside the tubular portion 3a, a heat generating portion formed by a heater or the like for warming the air and a blower portion formed by a motor or the like for blowing air (both not shown). And the like, and the handle portion 3b is provided with a switch 41 for controlling the operation of the heat generating portion and the blower portion, and a cord 42 for supplying power. Also the dryer body 3
At the tip of the cylindrical portion 3a, there is provided an air blowing port 4 through which hot air or cold air is blown, and a throttle nozzle 13 is detachably attached to the air blowing port 4. The throttle nozzle 13 is a cylindrical body in which the opening at the tip thereof is narrowed down from the blower opening 4 to form the exhaust opening 14, and the rear side opening is formed to have substantially the same diameter as the blower opening 4. Dryer body 3 on the edge
An engaging projection 12 which is engageable with a locking piece 11 provided over the entire length of the blower port 4 is formed over the entire length. Then, by engaging the engaging projection 12 with the locking piece 11 and attaching the throttle nozzle 13 to the blower port 4, the throttle nozzle 13 can narrow down the warm air or the cold air blown from the blower port 4, and The hair is easily set by blowing cold air in a concentrated state. When drying the hair, the squeezing nozzle 13 is removed from the air blowing port 4 so that hot air or cold air is directly blown out from the air blowing port 4, and hot air or cold air is blown onto the hair without being narrowed down. It was a thing.

However, since the number of women with long hair has increased in recent years due to changes in hair styles, there has been a problem that hair is scattered even with hot or cold air blown from the blower port 4 of the dryer body 3. Therefore, it has been attempted to diffuse the warm air and the cold air blown from the blower port 4. 63-
In Japanese Patent No. 37105, there is proposed a diffusion nozzle having an exhaust port 14 having an opening area larger than that of the ventilation port 4, and this diffusion nozzle is attached to the ventilation port 4 to prevent hot air or cold air blown from the exhaust port 14. It is an attempt to spread it.
Also, Japanese Utility Model Publication No. 63-48503 and Japanese Utility Model Publication No. 58-68.
No. 206 and No. 57-166809,
A nozzle has been proposed in which the opening area of the exhaust port 14 is adjustable, and the opening area of the exhaust port 14 can be narrowed or expanded to freely adjust the concentration or diffusion of hot or cold air as necessary. It was made possible.

Since the end portion is provided with engaging means that is engageable with the blower opening of the dryer body and the end portion of the inner cylinder on the large diameter side of the outer cylinder is provided with the engaging means that is engageable with the blower opening of the dryer body, By engaging the engaging means provided on the small-diameter end of the outer cylinder with the blower opening of the dryer body, hot air or cold air is diffused and blown out from the opening of the large-diameter end of the outer cylinder. Also, by engaging the engaging means provided at the end of the inner cylinder on the large diameter side of the outer cylinder with the air outlet of the dryer body, hot air or cold air is concentrated from the opening at the end of the inner cylinder. That can be blown out with a simple structure, and the concentration and diffusion of hot and cold air blown out with one nozzle can be adjusted freely A.

Further, a base nozzle is provided at the blower port of the dryer body, and one end has a large diameter and the other end has a small diameter. Since the fitting means which can be freely fitted is provided, the opening means of the enlarged large-diameter end portion of the tip nozzle is opened by engaging the engaging means provided at the small-diameter end portion of the tip nozzle with the tip opening of the base nozzle. The hot air or cold air can be diffused and blown out. Also, by engaging the engaging means provided at the wide end of the tip nozzle with a large diameter with the tip opening of the base nozzle, warm air or cold air is concentrated and blown out from the opening of the tip end of the small diameter. Is something that can be done.

Further, the tip end of the nozzle body provided at the blower opening of the dryer body is formed so as to be able to open wide between the state where it is opened wide and the state where it is opened small, and a wind direction plate is provided in the nozzle body to enlarge the nozzle body. The engaging means capable of engaging with the blower opening of the dryer body in the opened state is provided at the base of the nozzle body, and the engaging means capable of engaging with the blower opening of the dryer body in the opened state of the nozzle body winds. Since it is provided on the plate, it is possible to hold the nozzle body in a wide open state by engaging the engaging means of the nozzle main body with the blower opening of the dryer main body, and from the opening of the large open end of the nozzle main body. It is capable of diffusing hot air or cold air and blowing it out.
Further, the nozzle body can be held in a small opened state by engaging the engaging means provided on the airflow direction plate with the blower opening of the dryer main body, and hot air can be discharged from the opening of the small opened end of the nozzle body. The cold air can be concentrated and blown out.

In addition, a base nozzle is provided at the blower opening of the dryer main body, and an external nozzle is provided at the tip of the base nozzle, so that the tip of the external nozzle can be opened wide between a state where it is wide open and a state where it is small. The external nozzle is provided with engaging means capable of engaging with the tip opening of the base nozzle when the external nozzle is wide open, and can be engaged with the tip opening of the base nozzle when the external nozzle is small open. Since the engaging means is provided at the base of the external nozzle, the engaging means provided on the outer surface of the external nozzle can be held in a state where the external nozzle is greatly opened by engaging with the tip opening of the base nozzle. The hot air and the cold air can be diffused and blown out from the opening of the large opening end of the external nozzle. The engaging means provided at the base of the external nozzle is engaged with the tip opening of the base nozzle, so that the external nozzle can be kept in a small opening state, and the opening from the small opening end of the external nozzle can be maintained. The wind and cold air can be concentrated and blown out.
