Description

The present invention relates to a hair dryer and particularly to a hair dryer with an improved nozzle.

As shown in Patent Documents 1 and 2 below, the current hair dryer consists of two nozzles, an inner nozzle and an outer nozzle. The inner nozzle is fixed to the discharge port of the hair dryer, and the outer nozzle is rotated to rotate the air passage. A rotary nozzle that opens and closes and adjusts the wind speed is known.

That is, in the hair dryer shown in Patent Document 1 below, a rotary lid is rotatably attached to a nozzle body having a normally open type central nozzle port and vertical and left and right openable side nozzle ports, and the rotary lid is rotated. By opening the upper and lower side nozzles and closing the left and right side nozzles, the wind is in the vertical direction, and by opening the left and right side nozzles and closing the upper and lower side nozzles, the left and right sides are horizontal. It is a configuration that switches between the wind and the wind.

Further, the hair dryer shown in Patent Document 2 below is an improved version of the hair dryer shown in Patent Document 1, and an outlet grill having a higher rigidity than the nozzle is press-fitted into the inner circumference of the nozzle. The roundness of the nozzle can be corrected, and the shutter (rotary lid in Patent Document 1) can be smoothly slid along the inner circumference or the outer circumference of the nozzle.

However, the current rotary nozzle requires a rotating ring that makes it easier to grasp the rotating portion when the outer nozzle is rotated, which is a factor that impairs the aesthetic appearance. Further, as shown in Patent Document 1 or 2, in order to smoothly rotate the rotary lid with respect to the nozzle, various measures such as increasing the accuracy and increasing the hardness of the material are required, and the rotary nozzle has a rotary nozzle. At present, the one that works well has not been completed for the cost.

An object of the present invention is to eliminate the need for a rotating ring and improve the aesthetic appearance by adopting a sliding nozzle instead of the current rotating nozzle.

The hair dryer according to claim 1 of the present invention includes a hair dryer main body provided with a blower and a heater inside and a discharge port provided at the tip, and a nozzle set attached to the discharge port of the hair dryer main body. The nozzle set is attached so as to cover the inner nozzle detachably attached to the discharge port of the hair dryer main body and the inner nozzle, and can be pulled out or pushed in the wind discharge direction of the inner nozzle. The inner nozzle comprises a sliding outer nozzle, and the inner nozzle includes a tubular inner nozzle base portion attached to the discharge port of the hair dryer main body, a ventilation guide extending from the inner nozzle base portion, and the ventilation guide. A closed tongue that extends vertically from both ends near the tip, a first vent between the closed tongue and the inner nozzle base, and a second vent formed at the base of the ventilation guide. The outer nozzle is composed of a mouth, a ventilation passage formed by the closed tongue portion and the ventilation guide, and the outer nozzle includes a tubular outer nozzle base portion, a central nozzle opening at the tip portion of the outer nozzle base portion, and the like. At the positions of the sub-nozzle port provided at the base of the central nozzle port, the shutter portion of the outer nozzle base portion that closes the second ventilation port of the inner nozzle, and the side end portion in the outer nozzle. It consists of a side nozzle port extending in the wind discharge direction at the tip of the shutter portion so as to communicate with the sub nozzle port, and when the outer nozzle is pushed in the wind discharge direction of the inner nozzle, the closing tongue of the inner nozzle is closed. When the part closes the sub-nozzle opening of the outer nozzle and the second ventilation port of the inner nozzle is opened so as to be ventilated from the side nozzle opening of the outer nozzle, and the outer nozzle is pulled out in the air discharge direction of the inner nozzle. The closed tongue of the inner nozzle opens the sub-nozzle opening of the outer nozzle, and the second ventilation port of the inner nozzle is closed by the shutter portion of the outer nozzle.

The number of the ventilation guide, the closed tongue portion, the first ventilation port, the second ventilation port, the sub-nozzle port, the shutter part, and the side nozzle port is not limited, but as shown in Examples described later. , It is preferable to provide a pair of each because the air volume and the air direction are well-balanced on the left and right and the top and bottom.

In the hair dryer according to claim 2 of the present invention, in addition to the configuration of the hair dryer according to claim 1, an inner nozzle slide groove portion is formed in the vicinity of the second ventilation port of the ventilation guide of the inner nozzle, and the outer nozzle slide groove portion is formed. An outer nozzle slide rail portion is formed in the vicinity of the shutter portion of the nozzle, and the outer nozzle slide rail portion of the outer nozzle and the inner nozzle slide groove portion of the inner nozzle are engaged with each other.

The number of the inner nozzle slide groove portion and the outer nozzle slide rail portion provided is not limited, but as shown in Examples described later, it is preferable to provide the inner nozzle slide groove portion and the outer nozzle slide rail portion in pairs on the upper and lower sides because the stability is improved. ..

The hair dryer according to claim 3 of the present invention comprises a hair dryer main body provided with a blower and a heater inside and a discharge port provided at the tip, and a nozzle set attached to the discharge port of the hair dryer main body. The nozzle set includes an inner nozzle detachably attached to the discharge port of the hair dryer main body and an outer nozzle that is mounted so as to cover the inner nozzle and slides so as to be pulled out or pushed in the wind discharge direction of the inner nozzle. The outer nozzle is provided with a central nozzle port at the tip of the outer nozzle base portion and a sub nozzle port provided at the base portion of the central nozzle port, and either the outer nozzle is pulled out or pushed in. In some cases, the sub-nozzle opening of the outer nozzle is opened to form a ventilation path, and when the other is performed, the sub-nozzle opening of the outer nozzle is closed.

Since the hair dryer according to the present invention employs a sliding nozzle, the ring when the rotary nozzle described in the background technology is adopted becomes unnecessary, the aesthetic appearance can be improved, and the background technology can be used. Unlike a rotary nozzle, there is no need to make the rotation smooth or to select a material, and there is an advantage that the manufacturing cost is low.

In addition, the gap between the inner nozzle and the outer nozzle is reduced, and the wind speed is increased when the cross-sectional area of the air passage is narrowed, so that the hair can be dried quickly.

Further, there is a sharp change in the blast state, such as a slit-shaped blast for setting hair and a spot-shaped or focus-shaped blast for drying hair, and a switching effect is exhibited. In the case of spot-shaped or focused-shaped blast, the wind is concentrated in a narrow area, and the wind with high wind pressure is blown to the hair, so that the wind reaches the inside and root of the hair bundle even after bathing wet hair. Therefore, the drying time becomes faster.

It is a nozzle that is detachably attached to the air outlet of a hair dryer, and is composed of two members, an outer nozzle and an inner nozzle.

The inner nozzle is attached to the outlet of the hair dryer. The outer nozzle is mounted so as to cover the outside of the inner nozzle, and is freely attached to the inner nozzle by pulling out and pushing.

The wind speed, air volume, and direction of the wind blown from the hair dryer are adjusted by pulling out or pushing the outer nozzle with respect to the inner nozzle. It is not a type that adjusts the wind speed by rotating the outer nozzle with respect to the inner nozzle like the hair dryer shown in the background technology.

Next, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIGS. 1 and 2, the hair dryer A in this embodiment is composed of a hair dryer main body B and a nozzle set C. The hair dryer main body B is provided with a blower B1 and a heater B2 inside, and a discharge port B3 is provided at the tip of the hair dryer main body B in which air is blown by the blower B1 in the wind discharge direction. The nozzle set C is detachably attached to the discharge port B3 of the hair dryer main body B.

The nozzle set C is composed of an inner nozzle 10 and an outer nozzle 30. The inner nozzle 10 is detachably attached to the discharge port B3 of the hair dryer main body B. The outer nozzle 30 is mounted so as to cover the inner nozzle 10. The outer nozzle 30 is configured to slide in the wind discharge direction of the inner nozzle 10 so that it can be pulled out from the inner nozzle 10 and can be pushed in.

As shown in FIG. 3, the inner nozzle 10 is mainly composed of a tubular inner nozzle base portion 12, a pair of upper and lower closed tongue portions 16, and a pair of left and right ventilation guides 18. The tubular end of the inner nozzle base portion 12 on the side opposite to the wind discharge direction is attached to the discharge port B3 of the hair dryer main body B. The closed tongue portion 16 extends from the inner nozzle base portion 12, and has a pair of upper and lower first ventilation holes 14 between the inner nozzle base portion 12 and the closed tongue portion 16. Further, the ventilation guide 18 is also extended from the inner nozzle base portion 12, and a second ventilation port 20 is formed at the base of the ventilation guide 18, respectively. A ventilation passage 22 is formed in the inner nozzle 10 by the portion surrounded by the closed tongue portion 16 and the ventilation guide 18.

As shown in FIG. 4, the outer nozzle 30 mainly includes a tubular outer nozzle base portion 32, a central nozzle port 34, a pair of upper and lower sub nozzle ports 36, a pair of left and right shutter portions 38, and a pair of left and right nozzles. It is composed of a side nozzle port 40. The central nozzle port 34 is formed at the tip of the outer nozzle base portion 32 in the wind discharge direction. The sub nozzle ports 36 are provided on both the upper and lower sides of the base of the central nozzle port 34. The shutter portion 38 is provided at a portion of the outer nozzle base portion 32 that can close the second ventilation port 20 of the inner nozzle 10.

Then, as shown in FIG. 5, the outer nozzle 30 is mounted so as to cover the inner nozzle 10. FIG. 6 shows a state in which the outer nozzle 30 is pushed into the inner nozzle 10, and FIGS. 7 and 8 show a state in which the outer nozzle 30 is pulled out from the inner nozzle 10.

FIG. 9 shows the flow of wind when the outer nozzle 30 is pushed into the inner nozzle 10. When the sub-nozzle port 36 of the outer nozzle 30 that was open when the outer nozzle 30 was pulled out pushed the outer nozzle 30 in the wind discharge direction of the inner nozzle 10, as shown in FIG. 9, the inner nozzle 10 Closed by the closed tongue 16.

At that time, the shutter portion 38 of the outer nozzle 30 that closed the second ventilation port 20 of the inner nozzle 10 when the outer nozzle 30 was pulled out is displaced to the opposite side in the wind discharge direction by pushing the outer nozzle 30 and the inner nozzle. The second ventilation port 20 of 10 is opened, and the second ventilation port 20 of the inner nozzle 10 is opened so as to be ventilated from the side nozzle port 40 of the outer nozzle 30.

Therefore, the air blown from the inner nozzle 10 is blown from the central nozzle port 34 of the outer nozzle 30 as indicated by the arrow a, and the air blown from the sub nozzle port 36 is closed by the closed tongue portion 16, so that the sub nozzle port 36 is closed. The amount of air blown from the side nozzle port 40 is blown from the side nozzle port 40 as indicated by the arrow b.

In this case, the air blown from above and below the outer nozzle 30 emitted from the sub nozzle port 36 is stopped by the closed tongue portion 16, and the air is blown out from the central nozzle port 34 and the side nozzle port 40 of the outer nozzle 30. The ventilation area in the vertical direction is narrowed, resulting in a so-called slit-shaped wind with a horizontally long spread. This slit-shaped wind makes it easier to set the hair and shortens the hair setting time.

FIG. 10 shows the flow of wind when the outer nozzle 30 is pulled out from the inner nozzle 10. When the sub-nozzle port 36, which was closed by the closed tongue portion 16 when the outer nozzle 30 was pushed into the inner nozzle 10, pulled out the outer nozzle 30 in the wind discharge direction of the inner nozzle 10, the inner nozzle The sub-nozzle opening 36 is displaced from the closed tongue portion 16 of the 10 in the wind discharge direction and opens.

At that time, the second ventilation port 20 of the inner nozzle 10 that was open when the outer nozzle 30 was pushed in, the shutter portion 38 of the outer nozzle 30 was displaced in the wind discharge direction by pulling out the outer nozzle 30, and the second ventilation port 20 of the inner nozzle 10 was opened. 2 Ventilation port 20 will be closed.

Therefore, along with the opening of the sub-nozzle port 36, the second ventilation port 20 of the inner nozzle 10 is closed by the shutter portion 38 of the outer nozzle 30, so that the air blown from the second ventilation port 20 goes toward the sub-nozzle port 36. The air blown from the inner nozzle 10 is blown from the central nozzle port 34 of the outer nozzle as indicated by the arrow a, and is blown from the upper and lower sub nozzle ports 36 of the outer nozzle as indicated by the arrow c.

In this case, as for the air blown from the inner nozzle 10, the air blown from the central nozzle port 34 of the outer nozzle and the air blown from the sub-nozzle ports 36 above and below the outer nozzle are concentrated in the central direction, and the outer nozzle 30 is pushed into the inner nozzle 10. The area through which the wind passes is larger than in the normal state, resulting in a spot-like or focus-like blower with an almost circular cross section. Since this spot-like or focus-like wind is blown out in a concentrated manner, even if the hair is heavily wet due to the high-pressure wind being blown, the wind reaches the inside of the hair bundle and the root of the hair, and the drying time of the hair is short. Become.

Further, in this embodiment, in order to make it easier for the outer nozzle 30 to slide in the wind discharge direction with respect to the inner nozzle 10, the inner nozzle 10 is provided with an inner nozzle slide groove portion 24 as shown in FIGS. 3 and 4. The outer nozzle 30 is formed with an outer nozzle slide rail portion 44.

That is, the inner nozzle slide groove portion 24 is formed in the vicinity of the second ventilation port 20 of the ventilation guide 18 of the inner nozzle 10, and the outer nozzle slide rail portion 44 is formed in the vicinity of the shutter portion 38 of the outer nozzle 30. Since the outer nozzle slide rail portion 44 of the outer nozzle 30 and the inner nozzle slide groove portion 24 of the inner nozzle 10 are engaged, the outer nozzle slide rail portion 44 is guided by the inner nozzle slide groove portion 24 and the outer nozzle 30 is always directed in a fixed direction. Will slide with respect to the inner nozzle 10.

The inner nozzle slide groove portion 24 of the inner nozzle 10 has a recess in the inner nozzle slide groove portion at two positions, a position where the outer nozzle 30 is pushed in and a position where the outer nozzle is pulled out, according to the sliding distance of the outer nozzle 30. 25a and 25b are formed, and the end portion of the outer nozzle slide rail portion 44 of the outer nozzle 30 opposite to the wind discharge direction, that is, the inner recess 25a of the inner nozzle slide groove portion when the outer nozzle 30 is pushed in. When the outer nozzle 30 is fitted and the outer nozzle 30 is pulled out, the outer nozzle slide rail portion upper convex portion 45 that fits into the inner nozzle slide groove inner recess 25b is formed. As a result, when the pushing and pulling out of the outer nozzle 30 is completed, a clicking sound is generated and the feeling of fitting is transmitted, so that the click feeling can be felt, so that the pushing and pulling operations of the outer nozzle 30 can be performed lightly. There are advantages.

Further, in this embodiment, as shown in FIGS. 3 and 4, an inner nozzle locking convex portion 26 is formed at the end of the inner nozzle 10 on the side of the second ventilation port 20 in the wind discharge direction, and the outer nozzle 30 is formed. A side nozzle bar 46 is formed at the end of the side nozzle port 40 in the wind discharge direction. As a result, when the outer nozzle 30 is pushed into the inner nozzle 10, when the push of the outer nozzle 30 reaches a predetermined position, the side nozzle bar 46 of the outer nozzle 30 comes into contact with the inner nozzle locking convex portion of the inner nozzle 10 and is outside. The nozzle 30 is not pushed too much.

Furthermore, in this embodiment, as shown in FIGS. 3 and 4, the end of the inner nozzle base portion of the inner nozzle 10 is located at a position close to the discharge port B3 of the hair dryer A. An inner nozzle engaging portion 28 that circulates around the portion, and a ring-shaped recess 28 in this embodiment are formed, and outer nozzles are formed at two locations on the inner side of the outer nozzle base portion opposite to the wind discharge direction of the outer nozzle 30. The engaging portion 48 is formed. As a result, when the outer nozzle 30 is pushed into the inner nozzle 10, the inner nozzle engaging portion 28 of the inner nozzle 10 and the outer nozzle engaging portion of the outer nozzle 30 engage with each other, and the inside of the outer nozzle 30 is engaged. The fixing to the nozzle 10 is stable, and the outer nozzle 30 is prevented from being pushed too much into the inner nozzle 10.

The engagement of the inner nozzle engaging portion and the outer nozzle engaging portion is not limited to the concave-convex engagement, and modification examples such as pinching engagement are possible, but the concave-convex engagement is manufacturing and simple. Preferred in terms of points.
