Description

[Detailed Description of the Invention] Industrial Field of Use The present invention relates to an improvement in a wind collection nozzle provided at the tip of a blower tube in a hair dryer, particularly an air collection nozzle that is provided so as to be adjustable forward and backward.

2. Description of the Related Art In general, hair dryers are sometimes used with an air collection nozzle attached to the tip of the blower tube (as an attachment or integrally) for the purpose of increasing the force of hot air (or cold air) discharged.

As an improvement to this air collection nozzle, a structure in which the air collection nozzle is provided so that it can be adjusted forward and backward, specifically, the air collection nozzle is provided so that it can be moved forward and backward, and by making the nozzle protrude, the discharge port can be adjusted. A device that can narrow the opening area and thereby make it possible to blow out strong wind concentratedly on the hair (aperture adjustment effect) (Utility Model Publication No. 52-33435), or a wind collection nozzle. By forming the nozzle into a pair of upper and lower nozzle pieces and protruding both nozzle pieces together, a normal nozzle action can be obtained. In addition, by making only one of the nozzle pieces protrude, The discharge direction can be changed (wind direction adjustment effect) (Utility development 58-
No. 49609) has been proposed.

Problems to be solved by the invention However, in both of the above proposals, although the former can adjust the throttle of the discharge air, it is not possible to change the wind direction, and the latter cannot change the direction of the discharge air. In other words, in both proposals, either the discharge air throttling adjustment action or the wind direction change action can be obtained, but it is not possible to obtain both actions at the same time. The problem is that it cannot be obtained on a regular basis, and its uses are limited.

The present invention is an attempt to improve the above-mentioned problems in order to solve the above-mentioned problems. Our goal is to provide nozzles.

The specific means and actions for solving this problem are as follows.

Means for solving the problem A tapered part is formed so that it narrows toward the tip and gradually widens in both width directions, and an elongated rectangular shape is formed at the tip of the tapered part. A nozzle tube is provided with a discharge port opened, and a tapered piece is formed in correspondence with the tapered part, and the tip of the tapered piece has legs at both ends so as to form one side of the discharge port. A pair of nozzle pieces are provided by integrally connecting discharge pieces bent into a gate shape.

The nozzle pieces are arranged in such a manner that the legs formed at both ends of both the nozzle pieces engage with each other, and the tapered pieces slide along the tapered parts so that both the nozzle pieces can protrude and retract from the outlet. Fits into the cylinder so that it can move forward and backward.

Elongated guide holes extending in the front-rear direction are opened in both tapered parts, and guide pins that connect one end to the tapered piece are inserted into both guide holes, and the other ends of both guide pins are inserted into both guide holes. An operation button is provided which is in sliding contact with the surface of the tapered portion and has a size sufficient to cover the guide hole.

Function: By simultaneously protruding both nozzle pieces, the opening area of the discharge port can be narrowed, thereby making it possible to discharge even stronger discharge air to the hair in a concentrated manner ( aperture adjustment effect).

By protruding only one of the two nozzle pieces, the direction of the discharged air can be restricted to a specific direction (wind direction adjustment effect).

Since a gate-shaped discharge piece is provided at the tip of both nozzle pieces in parallel with the outlet of the nozzle tube, cold or hot air can be constantly discharged without creating a swirling flow at the outlet of the nozzle tube. It can be discharged parallel to the outlet.

The discharge pieces are formed in a gate shape and are provided so as to interlock with each other, so that when the nozzle piece is protruded, the legs formed at both ends of the discharge piece come into contact with the oppositely facing discharge piece. is obtained. That is, a minimum opening area can be ensured.

Specific embodiments of the present invention will be described below with reference to the drawings shown in FIGS. 1 to 6.

Embodiment 1 is a case body formed to extend in the front-rear direction, 2 is a handle portion extending downward from a rear end portion of the case body 1, and the handle portion 2 has a rear wall. Turn on the power switch S while facing the
However, there is also a control volume facing the front wall.
VR is provided for each.

The case main body 1 has a storage chamber 3 for a motor and a fan at the rear end, and a blower tube 4 facing forward.
The air collecting nozzle 5 is detachably attached to the front end of the air collector nozzle 5 as an attachment.

The air collecting nozzle 5 consists of a nozzle tube 6 and a pair of nozzle pieces 7, 7, as described later.
A tapered portion 6B is formed at the tip of the nozzle tube 6.
The nozzle tube 6 is formed by being inserted into the nozzle cylinder 6 so as to be able to move forward and backward, and the discharge pieces 7B, 7B formed at the tip of the nozzle tube 6 being able to protrude and retract from the discharge port 8 formed at the tip of the nozzle tube 6.

More specifically, the nozzle tube 6 has a cylindrical portion 6A at its base (rear end), and has a pair of fan-shaped flattened portions 9 at its tip, which gradually narrow toward the front. It is formed by providing a tapered part 6B so as to expand in both width directions, and a discharge port 8 is opened at the tip of the tapered part 6B via a discharge frame part 10 formed in an elongated rectangular shape. be done. The flat parts 9, 9 forming the tapered part 6B are provided with a guide hole 11 extending in the front-rear direction and formed into a long hole shape.
A plurality of recesses 12a and 12b are provided on the inner surface of the guide hole 11 on an extension line of the stop line along the longitudinal direction of the guide hole 11. When the nozzle pieces 7, 7 are inserted into the nozzle tube 6 so as to be able to move forward and backward along the tapered part 6B as described above, both nozzle pieces 7, 7 slide on the inner surfaces of the flat parts 9, 9. Tapered piece 7 formed in a fan shape so that it can touch
A and a discharge piece 7B that extends horizontally from the tip of the tapered piece 7A, and the discharge piece 7B is formed into a gate shape by bending both ends in the width direction at right angles.

Further, a guide pin 13 is provided protruding from the tapered piece 7A in correspondence with the guide hole 11, and the guide pin 13 is fitted into the guide hole 11 so as to be movable forward and backward along the longitudinal direction thereof. The operation button 1 is located at the tip of the guide hole 11 protruding from the guide hole 11.
4 is attached so as to be in sliding contact with the surface of the flat part 9. Further, by providing a slit 15 along the outer periphery of the tapered piece 7A, a plate spring portion 16 is formed between the slit 15 and the outer periphery, and the plate spring portion 16 has the following features: The depressions 12a, 12
A protrusion 17 is bored corresponding to b. That is, by moving the nozzle pieces 7, 7 back and forth along the tapered portion 6B, the protrusion 17 can be selectively engaged with the depressions 12a, 12b through elastic deformation of the leaf spring portion 16. provided as possible. Although the guide pin 13 is formed in the shape of a round bar in the above embodiment, it is preferably formed in the shape of a square bar.

Next, its effect will be explained.

1 and 3 are drawings showing a state in which both nozzle pieces 7, 7 have slid toward the tip of the nozzle tube 6, and in this way, both nozzle pieces 7,
7 slides toward the tip of the nozzle tube 6, the projection 17 formed on the tapered piece 7A forms a depression 12a near the tip (close to the guide hole 11) through elastic deformation of the plate spring 16. The discharge pieces 7B, 7B formed at the tips of both nozzle pieces 7, 7 are in a state of being engaged with each other, and the discharge pieces 7B, 7B formed at the tips of the two nozzle pieces 7, 7 are in a state of protruding from the discharge opening 8, which opens at the tip of the nozzle cylinder 6.

That is, the opening of the discharge port 8 is narrowed by the discharge pieces 7B, 7B. In this state where the opening of the discharge port 8 is narrowed, hot air or cold air (discharged air) is discharged, and the discharged air is intensively blown against the hair with a stronger wind force than usual. is obtained. Such an effect can be obtained even more significantly by forming the discharge pieces 7B, 7B in a frame shape extending in parallel toward the tip end. That is, of course, when both nozzle pieces 7, 7 protrude from the discharge port 8 as described above, both nozzle pieces 7, 7 are connected to the discharge port 8.
In either case, cold air or hot air can be constantly discharged in parallel along both discharge pieces without creating a swirling flow at the opening of the discharge port 8. Also, in the state where the opening of the discharge port 8 is narrowed by both the discharge pieces 7B, 7B, both ends (legs) of the two discharge pieces 7B, 7B, which are bent into a gate shape, are opposite to each other. By being in mutual contact with the facing discharge pieces 7B, the opening of the discharge port 8 is not completely blocked, and a minimum opening area can be ensured. That is,
Abnormal overheating of the hair dryer when discharging hot air can be prevented.

Also, as mentioned above, both the discharge pieces 7B, 7B are connected to the discharge port 8.
By sliding one of the two nozzle pieces 7 toward the rear end in the more protruding state, the tapered piece 7A
The protrusion 17 formed on the plate comes out of the depression 12a through the elastic deformation of the leaf spring portion 16 and enters the other depression 12.
b, and the discharge piece 7B is retracted into the discharge port 8, that is, only the other discharge piece 7B is engaged with the discharge port 8.
A more prominent state can be obtained.

In this way, in a state where only one discharge piece 7B protrudes from the discharge port 8, more specifically, in a state where the discharge port 8 extends in the horizontal direction, only the discharge piece 7B located on the lower side protrudes from the discharge port 8. By discharging hot air or cold air (discharged air) upward in the state of
Effective spraying action can be obtained only on hair.

Moreover, contrary to the above, the discharge piece 7B located on the upper side
By discharging hot air or cold air (discharge air) in a state where only the discharge port 8 protrudes from the discharge port 8,
As shown in FIG. 5, the effect of spraying the hair downward in the direction in which the hair is laid (straightening effect) can be obtained.

Also, in a state where only the discharge piece 7B protrudes from the discharge port 8 as described above, by sliding the same nozzle piece 7 toward the rear end, both discharge pieces 7B, 7B are moved inside the discharge port 8. A state in which it can be retracted is obtained. And like this, both discharge pieces 7B,
By discharging hot air or cold air (discharged air) in a state where 7B is drawn into the discharge port 8, an effect of blowing the discharged air against the hair with normal wind force can be obtained.

Effects of the invention The invention is constructed as described above.
As shown above, it narrows towards the tip,
The nozzle tube has a tapered part formed to expand in the width direction, and has a nozzle tube with an elongated rectangular discharge opening at its tip, and a gate-shaped nozzle tube with one side of the discharge opening formed at the tip. A pair of nozzle pieces each having a discharge piece are provided, and both the nozzle pieces are moved forward and backward along the tapered part so that the two nozzle pieces formed at the tips of the nozzle pieces can be moved in and out of the discharge opening in a state where the two nozzle pieces are engaged with each other. By setting it up so that it can be done,
By making both discharge pieces protrude from the discharge port,
In addition to being able to strengthen the force of the discharge air and spray the hair intensively, the tip of the nozzle piece is provided with a discharge piece that is bent into a gate shape parallel to the opening of the discharge port. As a result, whether the nozzle piece is protruding from the nozzle tube or retracted into the nozzle tube, cold or hot air can always flow through the outlet opening without creating a swirling flow. It is possible to discharge in parallel along the discharge piece. In addition, in the present invention, both discharge pieces bent into a gate shape are provided so as to interlock with each other, and when both discharge pieces are pulled out from the opening of the discharge port, the legs formed at both ends of the discharge pieces are placed in the opposite surface. By allowing the discharge pieces to come into contact with each other, it has become possible to secure a minimum opening area without completely blocking the discharge port. And by being able to secure the minimum opening area in this way,
It has now become possible to effectively prevent abnormal overheating of a hair dryer when hot air is being discharged. In other words, it has become possible to improve its safety. In addition, by making only one of the discharge pieces protrude from the discharge port, the direction of the discharge air can be regulated, and the wind force and direction of the discharge air can be arbitrarily changed according to the purpose of use. I was able to do this. Furthermore, regarding this invention,
Elongated guide holes extending in the front-rear direction are opened in both tapered parts, and guide pins that connect one end to the tapered piece are inserted into both guide holes, and the other ends of both guide pins are inserted into both guide holes. By providing an operation button that is in sliding contact with the surface of the tapered part and is large enough to cover the guide hole, the nozzle piece can be moved into the nozzle by moving the operation button forward or backward. In both the state of protruding from the cylinder and the state of being retracted into the nozzle cylinder,
Since the elongated guide hole can be closed by the operation button, this combined with the shielding effect of the tapered piece on the back side reliably prevents the discharge air from leaking from the guide hole. Furthermore, since the guide hole can be covered and hidden by the same operation button, the guide hole is not exposed to the outside and its external appearance can be improved.
