Description

[Detailed Description of the Invention] The present invention relates to a hair dryer, and particularly to a hair dryer in which the hot air discharge area and the discharge direction are changed in the same discharge section.

A hair dryer is used for the purpose of drying and styling hair, but when drying, it is necessary to efficiently dry the entire hair in a short period of time. Furthermore, when styling hair, it is necessary to blow warm air only to the areas that require hair styling. That is,
This is because the warm air hits areas other than those that require hair styling, causing hair to scatter in these areas. To this end, we installed a pair of knobs on the discharge port side of the case to create a square-shaped wind direction plate inside the discharge port, and enlarged it to vary the opening area.
The discharge direction was changed by rotating a nozzle connected to the outside of the discharge port.

However, the variable opening area and the rotation of the nozzle as described above only have one or the other.
Due to structural and space considerations, it was not possible to have both. To be more specific, the variable opening area and the rotation of the nozzle operate in different directions, making the structure quite complex and requiring a large installation space, which is an important problem for hair dryers that need to be miniaturized. Summer.

The present invention improves the above problems and will be explained below with reference to the drawings. 1 is a pair of left and right housings 2
a, 2b, a case with a connecting port 3 formed on the front surface and an intake port 4 formed on the rear surface; 5, a locking protrusion formed in the one housing 2b forming the connecting port; 6, a locking ridge formed inwardly; protruding elongated projection, 7,
Reference numeral 7 indicates a fitting protrusion protruding inwardly from the upper and lower edges of the housing 2b, and 8 indicates fitting grooves 9, 9 whose outer diameter is slightly smaller than the inner diameter of the connecting port 3 and which are flared toward the rear upper and lower edges. A hollow fixing ring 11 has an outer diameter slightly larger than the inner diameter of the fixing ring 8 at the front. A hollow discharge ring (hereinafter referred to as a movable ring) has a rectangular opening 13 formed by providing apertures 12, 12 at two opposing locations, and guide pins 14, 14 provided on both inner walls; The discharge ring 11 is located with spaces S and S for sending hot air, and a rectangular discharge port 17 smaller than the opening 13 is formed by providing apertures 16 and 16 at two opposite locations in the front part. A guide groove 18 is formed and extends in the front-rear direction on both side walls.
18, and a plurality of locking pieces 19, 19..., 1 on each of the rear sides.
9, 19... are provided at the rear end of the locking piece.
0, 20..., 20, 20... are provided.

Next, to explain the assembly order, first, from an oblique direction, fit the fitting grooves 9, 9 of the fixing ring 8 into the fitting protrusions 7, 7 of one housing 2b, fit the protrusion 6 into the elongated hole 10, and then The fitting protrusions 7, 7 of the housing 2a are fitted into the fitting grooves 9, 9, and at the same time, the protrusion 6 is fitted into the elongated hole 10. In this state, the fixing ring 8 is prevented from moving in the front-rear direction by the engagement between the protrusion 6 and the elongated hole 10, and is prevented from moving in the rotational direction by the engagement between the fitting protrusions 7, 7 and the fitting grooves 9, 9. be done. Next, the discharge nozzle 15 is fixed by first storing it in the movable ring 11, and then using the guide pin 14,
14 are engaged with the guide grooves 18, 18, and the hook projections 20, 20... are engaged with the locking protrusions 5 of the housings 2a, 2b.

The movable ring 11 assembled in this manner can freely move back and forth and rotate on the fixed ring 8.

When drying the hair after washing, the movable ring 11 is slid forward on the upper surface of the fixed ring 8 to increase the opening area of the hot air. Guide pins 14, 14 slide horizontally with the longitudinal direction of the main body using guide grooves 18, 18 as guides. The horizontal sliding movement by this guide pin and guide groove is the opening 1 of the movable ring 11 during hair styling, which will be described later.
3 and the constricted portions 16, 16 of the discharge nozzle 15, and this movable ring 11
When moving beyond a predetermined position in the forward direction, use guide pin 1.
4, 14 and the ends of the guide grooves 18, 18 come into contact with each other. As described above, during drying, the spaces S, S between the air ring 11 and the discharge nozzle 15 are opened, and the opening area of hot air increases. That is, a part of the hot air is sent from the connection port 3 to the discharge nozzle 1 via the fixing ring 8.
5 and the others are discharged from the inner wall side of the fixing ring 8 through spaces S, S. Therefore, the speed of the hot air is reduced and the air is discharged over a wide area, so that drying can be accomplished in a short period of time.

When styling hair, move the movable ring 1 as shown in Figure 2 B.
1 to the rear of the fixing ring 8 so that the inner peripheral edge of the opening 13 matches the outer peripheral edge of the discharge port 17 of the discharge nozzle 15, thereby closing the spaces S and S and reducing the opening area of the hot air. At this time, the movable ring 11
The constricted parts 12 and 12 of the discharge nozzle 15
6 and 16 are substantially on the same plane, and the hot air passing through the inner wall of the fixing ring 8 is directed to the constricted portions 12, 12, 16, 16, respectively.
The hot air is then discharged from the discharge port 17 together with the warm air on the central side. Therefore, the wind speed of the hot air is increased and the hot air is discharged in a narrow area to prevent hair from scattering in other areas.

By the way, when changing the discharge direction during hair styling due to differences in hair style or handedness of the user, when the movable ring 11 is rotated, the discharge nozzle 15 is rotated by the engagement of the guide pins 14, 14 and the guide grooves 18, 18. The discharge nozzle 15 rotates by the hook projections 20, 20, . . . and the locking protrusion 5 by the rotation of the movable ring 11, and hot air can be obtained in a desired direction. That is,
The discharge port 17 of the discharge nozzle 15 can be turned in any direction perpendicular to the hot air discharge direction.

In this device, the movable ring is movable in the front-rear and rotational directions and can be stopped at any position, but since there is a concern that the discharge side portion may become hot and the resin portion may deform, causing the movable ring to wobble, a notch mechanism may be provided between the movable ring and the fixed ring to prevent wobble. Also, a fixed ring is provided between the movable ring and the discharge nozzle and the connecting port of the case, but this fixed ring is not necessarily required. For example, if the case is a cylindrical one-piece mold, the fixed ring is not required. In this case, it is sufficient to provide a step on the outer wall of the case on the connecting port side and a locking ridge on the inner wall.

As described above, the present invention has a case that has a connecting port at the front and an intake port at the rear, and an opening formed at the front, and the rear part is connected to the outside of the connecting port so that it can rotate and slide back and forth. A hollow discharge ring is located within the discharge ring with a space for sending hot air, a rectangular discharge opening smaller than the opening is formed in the front part, and the rear part is rotated to the connection port. a freely provided hollow discharge nozzle, the discharge ring and the discharge nozzle can be rotated in conjunction with each other by fitting a guide pin provided on one of them with a guide groove extending in the front-rear direction provided on the other; Since the opening is formed with a constriction portion that contacts the outer periphery of the discharge nozzle and closes the space by the backward sliding movement of the ring, the space for hot air discharge is opened by the forward sliding movement of the discharge ring, By discharging hot air from the rectangular outlet and space, hair can be dried efficiently in a short time, and the space for hot air discharge is closed by the backward sliding movement of the discharge ring, allowing hot air to be discharged from the rectangular outlet. Can be discharged only from the outlet. After the discharge ring is slid backwards, the rectangular discharge port can be moved in any direction by rotating the discharge ring, and the hot air collected in a flat shape can be discharged vertically or horizontally. Therefore, the range of movement of the hand that holds the hair dryer can be minimized and hair can be styled easily. Such adjustment can be performed with a simple structure without requiring a complicated mechanism unlike the conventional one, and without requiring a separate slide knob or the like. Furthermore, as described above, the shape of the ejection ring allows the sliding operation to be performed no matter where the ejection ring is gripped. Further, by fitting each of the discharge ring and the discharge nozzle into the guide pin and the guide groove extending in the front-rear direction, the sliding movement is ensured, the discharge ring can be positioned, and the rotation of the discharge nozzle can be reliably transmitted to the discharge nozzle.
