Description
BACKGROUND OF THE INVENTION

1. Technical Field

The present utility model relates to a hair dryer or the fitting for a hair dryer in the field of daily necessities, more specifically, to an airflow concentrator sleeved or fixed onto a hair dryer.

2. Description of Related Art

A hair dryer is a hairdressing apparatus commonly seen in hair salons or at home for private use, in order to rapidly dry hair. Generally, to meet the needs of different using situations, an airflow concentrator can be arranged on the air supply outlet of the hair dryer to achieve diversified hairstyles.

However, the airflow concentrator (also known as airflow nozzle/air nozzle) currently available in the market is basically made of plastic, and with single function only (airflow concentration generally). Moreover, considering the user's normal using demands, the top of the airflow concentrator often directly contacts hair and slides (for example, straighten long hair by means of the airflow concentrator). The all-plastic airflow concentrator, on one hand, is easy to create friction (rubbing effect) with hair and damage the hair cuticle so that hair becomes injured; on the other hand, heat that is originated from the hair dryer may partly dissipate after passing the airflow concentrator, thus causing that repeated operation on hair is required for getting desired effect. Therefore, it is necessary to develop an airflow concentrator capable of reducing heat loss and damage to hair which overcomes the structural drawbacks of the airflow concentrators in the prior art.

BRIEF SUMMARY OF THE INVENTION

In view of the deficiencies in the prior art, the present invention aims at providing an airflow concentrator for a hair dryer with a rolling mechanism mounted on the top so as to, on one hand, reduce contact between hair and the airflow concentrator to further protect hair cuticle; on the other hand, retain heat in the hair dryer, with the help of the metal rolling mechanism, to further reduce loss and realize perm-like effects by concentrating heat on hair directly.

To realize the objective described above, the present utility model employs the following technical solution:

an airflow concentrator for a hair dryer, comprising an airflow concentrator base, wherein the base can be sleeved onto the air supply outlet of the hair dryer at the bottom, characterized in that, a rolling mechanism is further included, two sets of through holes of positional correspondence are provided on the two sides of the top of the base, and the rolling mechanism is mounted in the top of the base by means of the two sets of through holes of positional correspondence and realizes rolling movement; the rolling mechanism includes a first rolling wheel, a second rolling wheel, a first rotation shaft, a second rotation shaft, rolling wheel caps and a shaft rivet, wherein the first rolling wheel and the second rolling wheel are provided with a hollow cylindrical slot body respectively and used to make the two ends achieve connectivity respectively, the rolling wheel caps which are mounted on the two ends of the first rolling wheel and the second rolling wheel are provided with a hollow cylindrical open-slot respectively and used to make the two ends achieve connectivity; the first rotation shaft and the second rotation shaft extend into the cylindrical slot body of the first rolling wheel and the second rolling wheel after passing the through holes of one side on the top of the airflow concentrator and the cylindrical open-slot on one end of the rolling wheel caps respectively, the shaft rivet extends into the cylindrical open-slot on the other end of the rolling wheel caps after passing the through holes of the other side on the top of the airflow concentrator; a slot fit for the size and shape of the shaft rivet is arranged on one end of the first rotation shaft and the second rotation shaft, and the shaft rivet and the slot are spliced together in the cylindrical open-slot of the rolling wheel caps.

It shall be noted that, the rolling wheel caps include a cap part and a cap body, wherein the cap body has an outer diameter less than the inner diameter of the cylindrical slot body of the first rolling wheel and the second rolling wheel, and the cap body is closely connected with the inner diameter of the cylindrical slot body; the outer diameter of the first rotation shaft, the second rotation shaft and the shaft rivet is less than the inner diameter of the cylindrical open-slot respectively.

In the prior art, to achieve better thermal conduction, the air supply outlet of the airflow concentrator must be perpendicular to the hair surface and the hand must hold it for a long time, so it is prone to cause hand fatigue. To reduce the occurrence of such cases, the top of the base is configured to be a slope structure, the second rolling wheel is lower than the first rolling wheel, thus it is possible to get better heat without the necessity of keeping it vertical to hair surface in use; secondly, when the airflow concentrator in the prior art is in use, the body must directly contact hair, which may lead to damage to the hair cuticle on the hair surface. Therefore, the rolling mechanism in the present utility model after assembly is slightly higher than the slope structure to avoid damage to hair (reduce friction and rubbing effect).

It shall be also noted that, as a preferable technical solution, to prevent hair from getting in the rolling mechanism in use, an isolating plate that extends into the top of the base downwards is arranged in the base; the isolating plate is located between the first rolling wheel and the second rolling wheel.

It shall be further noted that, to reduce the damage of mechanical rubbing effect from conventional plastic air concentrator to hair cuticle and better concentrate heat of the hair dryer, the first rolling wheel and the second rolling wheel are made of metals, such as aluminum.

As a preferable technical solution, to further increase the area contacting hair surface and enhance the concentrated heat effect, the first rolling wheel and the second rolling wheel can be replaced by several rolling wheel to realize another type of improvement.

The following is an alternative structure of the airflow concentrator for the present utility model. It shall be noted that,
