However, the hair dryer shown in the above-mentioned known document has a blow-off nozzle attached to its blow-off port consisting of an outer nozzle and an inner nozzle, which are mutually rotatably supported, so as to be able to switch between a diffusion posture and a convergence posture. However, either the outer nozzle or the inner nozzle is fixed to the outlet, and the outlet nozzle itself does not rotate with respect to the outlet, so the diffusion position or In either convergent position, the degree of freedom in the direction of the airflow relative to the hair is limited, and the hair dryer itself has to change its position to apply the airflow to the hair, making it inconvenient to use. . Further, although the outer nozzle and the inner nozzle are configured to be rotatable, there is no means for regulating this rotation, and there is a problem that they may rotate inadvertently.

The present invention is a nozzle for a hair dryer that is composed of an inner nozzle and an outer nozzle, and is capable of diffusing and converging airflow by making the inner nozzle and the outer nozzle freely rotatable. Not only is it rotatable, but it is also rotatable relative to the hair dryer's outlet, so that the inner nozzle can be loosely fixed to the outlet, and the outer nozzle can be loosely fixed to the inner nozzle. It can be fixed.

It is characterized in that it is rotatably connected to.

With the above configuration, the outer nozzle and the inner nozzle rotatably engage with each other, and the inner nozzle and the air outlet of the hair dryer rotatably engage with each other.

As a result, since the outer nozzle and inner nozzle are rotatable, the outer nozzle rotates relative to the inner nozzle and changes its position, changing the airflow blown out from the hair dryer into four or more patterns. can.

That is, the inner engagement recess on the inner first engagement protrusion of the inner nozzle engages with the engagement protrusion on the outer nozzle, and the engagement protrusion on the outer nozzle and the inner first engagement protrusion come into contact. At this time, by rotating the outer nozzle, the inner nozzle rotates along the outlet. In this way, since the inner nozzle and the hair dryer outlet are rotatable, the inner nozzle, which is integrated with the outer nozzle, rotates and changes its position with respect to the hair dryer outlet.

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

The hair dryer A in this embodiment is composed of a main body case B and a nozzle C, as shown in FIGS. 1 to 3. The main body case B is provided with a fan B1 and a motor B2 for driving the fan. When the fan B1 is activated and rotated by the motor B2, the air flow sucked in from the mesh air intake port B3 is generated. Air is generated, and as shown in FIG. 3, an air flow is blown out from an air outlet 10 provided at the tip of the main body case B in the wind ejection direction. As will be described later, the nozzle C is composed of an outer nozzle 20 and an inner nozzle 30, and the inner nozzle 30 is removably attached to the outlet 10 of the main body case B of the hair dryer. It can be attached to and detached from the main body case B.

Of course, the main body case B is equipped with a heater included in a typical hair dryer, although illustration and description are omitted, and the main body case B is configured to be able to switch between cold air and hot air.

As shown in FIGS. 3 to 5, the air outlet 10 is provided with one or more (four in this embodiment) engaging portions 11 around the inner surface of its end. serves to attach an inner nozzle 30, which will be described later, in a detachable and rotatable manner. Furthermore, the engagement portion 11 on the inner surface of the end of the air outlet 10 is provided with an inner surface engagement recess 12, and as described later, the inner nozzle 30 that rotates with respect to the air outlet 10 can be freely rotated. can be engaged with.

As shown in FIGS. 6(a) to 6(c), the outer nozzle 20 includes an outer air outlet 21 that opens at its tip, and outer side openings 22 that open at both sides of the outer nozzle 20. There is. Further, as shown in FIGS. 6(b), 6(d), and 6(e), the outer periphery of the rear end of the outer nozzle 20 is provided with an engaging convex portion 23 that engages with the inner nozzle 30 and an outer A connecting step portion 24 is provided.

As shown in FIG. 7, the inner nozzle 30 includes an inner air outlet 31 that opens at its tip, and inner side openings 32 that open continuously from the inner air outlet 31 on both sides of the inner nozzle 30. ing. Further, inner eaves portions 33 are provided in regions of both side portions in a direction intersecting the direction of both side portions in which the inner side openings 32 are formed.

Further, on the outer periphery of the rear end of the inner nozzle 30, as shown in FIGS. 40. Further, the first inner engagement convex portion 35 includes an inner engagement recess 36 , and the engagement convex portion 23 of the outer nozzle 20 engages with the inner first engagement concave portion 36 . On the other hand, the outer nozzle 20 is rotatable. Note that the relationship between the first inner engaging convex portion 35 and the inner engaging recess 36 is relative, and the first inner engaging convex portion 35 does not necessarily need to protrude, and the inner first engaging convex portion 35 does not necessarily have to protrude. This also includes a case where the inner engaging recess 36 is flat with the outer circumferential surface and is recessed from the outer circumferential surface. The point is that the inner engaging recess 36 is recessed and serves as a guide groove for the engaging protrusion 23. Further, the second inner engagement recess 38 includes one or more inner elastic parts 39 on its outer wall side, and the engagement part 11 of the air outlet 10 engages with the second inner engagement recess 38. This allows the inner nozzle 30 to rotate with respect to the outlet 10.

Furthermore, as will be described later, the inner engagement recess 36 is loosely fixed by engaging with the engagement protrusion 23 of the outer nozzle 20 from the boundary between the inner engagement recess 36 and the inner first engagement protrusion 35. The inner small convex portion 41 is provided at a position where the inner nozzle 30 and the outer nozzle 20 can be loosely fixed. Further, the inner elastic portion 39 is provided with a locking convex portion 42 on its tip side, as described later, and by engaging with the end inner surface engagement recess 12 of the outlet 10, and the inner nozzle 30 can be loosely fixed.

By configuring the outer nozzle 20 and the inner nozzle 30 in this way, as shown in FIGS. By engaging with the recess 36, it is rotatably connected to the inner nozzle 30. 8(a) and 8(c) show the connected state, and FIG. 8(b) shows the disassembled state.

Moreover, FIG. 9 shows a state in which the engagement protrusion 23 of the outer nozzle 20 is fitted into the inner engagement recess 36 of the inner nozzle. FIG. 10 shows a non-engaged state of the inner engagement recess 36 at a portion of the outer nozzle 20 where the engagement protrusion 23 is not formed. The engagement protrusion 23 of the outer nozzle 20 can move freely at the location where the inner engagement recess 36 of the inner nozzle is formed, so that the outer nozzle 20 can rotate relative to the inner nozzle 30. Become free.

As described above, by configuring the outer nozzle 20 and the inner nozzle 30 to be rotatable, the outer nozzle 20 can be rotated and the inner eaves of the inner nozzle 30 can be inserted into the outer side opening 22, as shown in FIG. The portions 33 can be overlapped. In this case, the airflow at the outlet is blown out from the nozzle C as a convergent flow. Further, as shown in FIG. 12, the outer nozzle 20 can be rotated so that the outer side opening 22 and the inner side opening 32 of the inner nozzle 30 overlap. In this case, the air flow at the outlet is blown out from the nozzle C as a diffusion flow. In this way, when the outer nozzle 20 is used in a horizontal position, it is suitable for drying and setting hair on the top of the head and the back of the head.

Then, when the outer nozzle 20 is rotated from the state shown in FIG. 13 and the engagement protrusion 23 of the outer nozzle 20 comes into contact with the inner first engagement protrusion 35 as shown in FIG. Rotation of the outer nozzle 20 stops. Further, as shown in FIGS. 13 and 14, the inner first engaging convex portion 35 can be rotated by 90 degrees, that is, the inner nozzle 30 can change from the state shown in FIG. 11 to the state shown in FIG. An inner engagement recess 36 is formed therein.

By configuring the air outlet 10 and the inner nozzle 30 as described above, the inner nozzle 30 engages the inner second engagement recess 38 of the inner nozzle 30 with the engaging part 11 on the inner surface of the end surface of the air outlet 10. By matching them together, they are rotatably connected to the air outlet 10. Further, when the outer nozzle 20 is further rotated from the stopped state of the outer nozzle 20 described above, the outer nozzle 20 and the inner nozzle 30 are integrally rotated with respect to the outlet 10. It turns out.

With the above configuration, the outer nozzle 20 and the inner nozzle 30 are rotatably engaged, and the inner nozzle 30 and the air outlet 10 of the hair dryer A are rotatably engaged.

Therefore, the inner engagement recess 36 of the inner first engagement protrusion 35 of the inner nozzle 30 engages with the engagement protrusion 23 of the outer nozzle 20, and by moving the outer nozzle 20, the inner nozzle 30 is blown. It rotates along the exit 10. As described above, since the inner nozzle 30 and the air outlet 10 of the hair dryer are rotatable, the inner nozzle 30 integrated with the outer nozzle 20 can rotate with respect to the air outlet 10 of the hair dryer A. The entire position of the nozzle C can be changed.

As a result, since the outer nozzle 20 and the inner nozzle 30 are rotatable, the outer nozzle 20 rotates relative to the inner nozzle 30 and changes its position, resulting in four patterns of airflow blown out from the hair dryer A. , or even more. That is, two typical patterns are the case where the outer nozzle 20 is set horizontally as shown in FIGS. 11 and 12, and the two patterns when the outer nozzle 20 is set vertically as shown in FIGS. 18 and 19. If the outer nozzle 20 is in a vertical position, it is suitable for drying and setting the temporal region and ends of hair. In this way, the air flow blown out from the air outlet 10 can be made into a vertical convergence flow, a diffusion flow, and a horizontal convergence flow, and a diffusion flow, which improves the usability of the user and allows the user to maintain a comfortable posture. It can dry and set hair.

Further, as described above, the inner engagement recess 36 of the inner nozzle 30 is provided with one or more inner small protrusions 41. When the engagement protrusion 23 of the outer nozzle 20 rides over the inner small protrusion 41 and fits between the first inner engagement protrusion 35 and the inner small protrusion 41. Then, the outer nozzle 20 is loosely fixed to the inner nozzle 30. FIG. 13 shows a state in which the inner small protrusion 41 of the inner nozzle 30 is at the position of the engagement protrusion 23 of the outer nozzle 20, and when the inner nozzle 30 is slightly rotated counterclockwise from this state, the reverse occurs. In other words, when the outer nozzle 20 is rotated clockwise, it becomes the state shown in FIG. The portion 23 is fitted and fixed. Since this inner small convex portion 41 is a small convex portion, it can be easily fixed by rotating the inner nozzle 30 clockwise from the state shown in FIG. 14 or by rotating the outer nozzle 20 counterclockwise. It can be released and becomes freely rotatable. In this way, the above-mentioned fixation is a loose fixation, so to speak. This loose fixation is to prevent the outer nozzle 20 from inadvertently rotating relative to the inner nozzle 30, thereby making the hair dryer easier to operate.

In this embodiment, as shown in FIGS. 13 and 14, two inner small protrusions 41 are formed in each of the inner engagement recesses 36 located at opposing positions, and one of the inner small protrusions 41 as shown in FIG. From the state in which one of the engagement protrusions 23 is in contact with the first inner engagement protrusion 35 and is loosely fixed, the outer nozzle 20 is rotated counterclockwise so that the one engagement protrusion 23 contacts the other one. It is designed so that when it comes into contact with the inner first engaging protrusion 35, it is loosely fixed in that position as well. These two loosely fixing positions are designed at an angle of 90 degrees, and by switching the loosely fixing positions, the two states shown in FIGS. 11 and 12 can be changed.

By providing the inner small protrusion 41 in the inner engagement recess 36 of the inner nozzle 30 in this way, the inner nozzle 30 and the outer nozzle 20 can be loosely fixed, and in this loosely fixed state, the user can If the nozzle 20 is slightly rotated in the opposite direction to release the loose fixation, the inner nozzle 30 and the outer nozzle 20 can easily become rotatable.

Further, as described above, the engagement portion 11 on the inner surface of the end portion of the air outlet 10 includes the inner surface engagement recess 12 , and the inner elastic portion 39 in the second inner engagement recess 38 of the inner nozzle 30 A locking protrusion 42 is provided. As shown in FIG. 7(d), the inner elastic portion 39 is a narrow portion separated by two cuts in a part of the second inner engagement recess 38, so that it is imparted with elasticity. Further, the end inner surface engaging recess 12 is a shallow recess, and the locking projection 42 is a slight projection, and as shown in FIG. When engaged, the inner nozzle 30 is loosely fixed to the outlet 10, that is, loosely fixed. When the inner nozzle 30 is rotated from this state, the engagement between the end inner surface engaging recess 12 and the locking protrusion 42, which are loosely fixed by the elasticity of the inner elastic part 39, is released, and as shown in FIG. The inner elastic portion 39 shown at 16 is engaged with the end inner surface engaging recess 12, and the inner nozzle 30 becomes rotatable with respect to the air outlet 10. Note that in locations where the engaging portion 11 is not formed, the outlet 10 is not engaged with the inner nozzle 30 as shown in FIG. 17, and is in a freely rotatable state.

With the above configuration, the end inner surface engaging recess 12 and the locking convex portion 42 of the inner elastic portion 39 of the inner nozzle 30 engage with the inner surface of the end portion of the air outlet 10, so that the inner nozzle 30 Since the position of is fixed, the direction of the air flow blown out from the air outlet 10 can be loosely fixed in the direction desired by the user.

As described above, in the hair dryer A according to the present embodiment, the nozzle C of the hair dryer A is composed of the inner nozzle 30 and the outer nozzle 20, and the inner nozzle 30 and the outer nozzle 20 are rotatable. , since the inner nozzle 30 is configured to be rotatable not only with respect to the air outlet 10 of the hair dryer A, as shown in FIGS. 11, 12, 18, and 19, the hair dryer A The airflow blown out from the air outlet 10 can be changed into four or more patterns, and the airflow blown out from the outlet 10 can be changed into vertical convergence, diffusion, horizontal convergence, and diffusion. It is easier for the user to use, and allows the user to dry and set hair in a comfortable position.
