Description

Hair drier and nozzle for the same}

The present invention relates to a hair dryer, and more particularly, to a hair dryer and a blower nozzle of the hair dryer having a structure that can stabilize the coupling and facilitate attachment and detachment when the nozzle is coupled to the blower of the hair dryer body. .

In general, a hair dryer is a device that generates electricity by operating a blower by supplying electricity, and generally has a structure and a form that can easily dry wet hair by supplying warm air with a heater, and often a case of a rod or pistol Has a form.

These hair dryers are basically provided with a blowing fan and a motor to form a blower for injecting the outside air to discharge the wind, it can be divided into rotary type and propeller type hair dryer according to the shape of the blowing fan.

1 is an exploded perspective view of parts showing an example of a conventional pistol type and propeller hair dryer.

The pistol-type case is largely divided into the handle part 1 and the barrel part, and the barrel part is divided into the front part 3 and the rear part 2 based on the position at which the handle part 1 is coupled. A heater (8) device such as a heating wire is coupled to the front part (3), a blower (7) is coupled to the rear part, and the handle (1) is a control switch (5) for the blower (7) and the heater (8). ) Is installed.

In another example, the front part of the handle and the front part of the barrel are integrally formed in the pistol case, and the rear part of the handle and the rear part of the barrel are integrally formed so as to combine the two parts. A similar form to the example may be achieved.

By the way, in these conventional examples, the nozzle is coupled to the tuyeres of the hair dryer body in a structure that is simply inserted into the sleeve coupling form as a separate component. The nozzle is made to control the shape and concentration of the wind coming out for hair processing, such as the wind outlet is formed to one side. In such a coupling structure, as the nozzle is inserted into the hair dryer, the coupling part becomes loose, and the nozzle is easily detached from the main body or the direction of the nozzle is easily distorted during use.

However, manufacturing by fixing a nozzle to a main body has a problem that a main body becomes large and the ease of use also falls. For example, if the nozzle angle is fixed, the position of the hand holding the hair dryer should be changed and used. If the handgun is not a simple rod type, it is difficult to change the position of the hand, which is inconvenient to bend the hand.

The present invention is to alleviate the above-mentioned problems of the prior art, and an object of the present invention is to provide a hair dryer that can be easily loosened when using a nozzle and prevents it from falling off the main body, and a blowing nozzle used therein.

In addition, another object of the present invention is to provide a hair dryer which is convenient for changing the air outlet shape by changing the engagement angle with the main body as necessary while maintaining the nozzle with the hair dryer main body stably.

The hair dryer of the present invention for achieving the above object is provided with a heater, a blower, a heater having a heater and a blower, and a nozzle made of a separate component coupled to the blower of the case, the nozzle and the case is fitted with a protrusion and the protrusion Loss is characterized in that the coupling structure is coupled to each other by a groove or hole.

In the present invention, the protrusion may be formed at the nozzle side, and the nozzle may be provided with a nozzle body and a coupling lever. At this time, the coupling lever is formed with the protrusion on one side, the pressing portion is formed on the other side, the intermediate portion for rotatably coupling the coupling lever to the nozzle body between the protrusion and the pressing portion may be provided. Therefore, when pressing the pressing part, the projecting part moves to the outside (outside from the center of the vent hole) by the principle of the lever with the middle part as a supporting point, releasing from the groove or hole forming the joining structure together, and releasing the pressing pressure at the pressing part. When the projection is bound to the groove or hole to join the nozzle and the case.

In the coupling lever of the present invention, the protrusion forming the coupling structure is installed close to the case, that is, the hair dryer body, and the pressing portion may be formed farther from the case than the protrusion, and the nozzle body has a passage hole for allowing the protrusion to contact the case. May exist.

The coupling lever of the present invention may be fastened to the nozzle body by a coupling pin at an intermediate portion such that the coupling pin serves as a rotational central axis of the coupling lever.

On the other hand, when the pressing part of the coupling lever is released, when the hand is released to restore the position, the branch is branched at the pressing part on the opposite side of the protrusion relative to the middle part, so that the elastic force acts between the pressing part and the branch part. have.

In addition, when the pressing part of the coupling lever is released to release the position when the hand is released, the middle portion or the pressing portion is further provided with a separate elastic body is fastened to the coupling lever, pressing the pressing portion of the compression body while pressing the pressing portion Escape from the hole or groove of the, and release the pressure on the pressing portion, the elastic body is restored while the protrusion is inserted into the hole or groove of the case, the nozzle and the case can be combined again.

In the present invention, the coupling structure of the protrusion and the groove or the hole is formed in the sleeve coupling section for coupling the nozzle and the case, and the coupling between the nozzle and the case may be combined with the sleeve coupling in addition to the coupling structure of the protrusion and the groove or the hole.

In the present invention, the coupling portion coupled to the case or the nozzle may have a plurality of coupling structures including a protrusion and a groove or a hole to adjust an angle at which the nozzle and the case are coupled to each other. For example, if the tuyere that is combined with the nozzle has a circular shape, a plurality of protrusions (protrusions) are formed so as to form an angle difference of 30 degrees, 45 degrees, or 90 degrees only in the peripheral semicircle or quarter circumference section of the tuyere in consideration of symmetry. One groove is formed in the nozzle to adjust the coupling angle with the blower of the nozzle. Of course, a groove or a hole may be formed in the case, and a protrusion may be formed in the nozzle. When only one protrusion is formed in the case and a plurality of holes or grooves are formed in the nozzle, a plurality of coupling structures may be formed in both. It is possible.

The present invention is further required for a pistol type dryer having a handle and a barrel shape, but it is also possible to increase the convenience of a circular bar type hair dryer.
