As the improvement of above-mentioned technology side, the air channel inwall of described alloy wind gathering mouth is coniform gathering along wind direction.
As the further improvement of above-mentioned technology side, described air inlet structure is arranged on the fresh air inlet on the sleeve's inner wall.
As the further improvement of above-mentioned technology side, described air inlet structure is arranged on the ventilation slot of collet end.
As the further improvement of above-mentioned technology side, described air inlet structure is arranged on the ventilation slot of collet end.
As the further improvement of above-mentioned technology side, described air inlet structure is arranged on the wind groove on the shell.
As the further improvement of above-mentioned technology side, described housing is fixedly formed by fore shell and back cover combination.
As the further improvement of above-mentioned technology side, the position that is positioned at fan in the described shell is provided with blimp.
The beneficial effects of the utility model: hair dryer of the present utility model is when using hot blast to carry out hair drying and shaping, the cold wind that fan blows out can enter into the cold air duct that forms between collet and the shell along air inlet structure, and blow out in the sawtooth hole of the zigzag back-up ring by air outlet outer ring place, thereby around the hot blast that alloy wind gathering mouth blows out, produce the cold wind circle, the convenient hair that drying is crossed carries out cooling and shaping timely, can prevent effectively that hair and scalp are by continuous hot-fluid damage.

The specific embodiment
Referring to figs. 1 through Fig. 6, a kind of hair dryer of the present utility model, comprise shell 1 with tubular wind-tunnel, be extended with handle 2 on the described shell 1, be provided with heater 3 in the described shell 1, fan 4 and be used to drive fan 4 motor rotating 5, described shell 1 air outlet place is provided with zigzag back-up ring 11, be placed with external diameter on the described zigzag back-up ring 11 and be slightly less than the alloy wind gathering mouth 6 of zigzag back-up ring 11 sawtooth external diameters, also be provided with the collet 7 that front end withstands the tubular of described alloy wind gathering mouth 6 in the described shell 1, described collet 7 rear ends are fixed or are fitted on the inwall of described shell 1, be formed with cold air duct 8 between the outer wall of described collet 7 front ends and the inwall of described shell 1, described heater 3 is arranged in collet 7, described fan 4 is positioned at collet 7 rear ends, and described collet 7 and/or shell 1 are provided with air inlet structure, the cold wind that described fan 4 blows out can enter into cold air duct 8 by air inlet structure, and blows out by the sawtooth mouth of zigzag back-up ring 11.Because the footpath of the sawtooth of zigzag back-up ring 11 is greater than the external diameter of alloy wind gathering mouth 6, so after alloy wind gathering mouth 6 is placed on the zigzag back-up ring 11, alloy wind gathering mouth 6 can not cover sawtooth fully, and therefore, the air-flow in the cold air duct 8 can blow out the hair dryer outside by the sawtooth mouth that is not covered.Hair dryer of the present utility model is when using hot blast to carry out hair drying and shaping, the cold wind major part that fan 4 blows out enters into main air duct, and added the thermosetting hot blast by heater 3 and blow out from alloy wind gathering mouth 6, and the cold wind of periphery can enter into the cold air duct 8 that forms between collet 7 and the shell 1 along air inlet structure, and the zigzag back-up ring 11 sawtooth mouths of locating by the air outlet outer ring blow out, thereby around the hot blast that alloy wind gathering mouth 6 blows out, produce the cold wind circle, the convenient hair that drying is crossed carries out cooling and shaping timely, can prevent effectively that hair and scalp are by continuous hot-fluid damage.
In order to improve electric energy rate aluminium, the air channel inwall 61 of described alloy wind gathering mouth 6 is coniform gathering along wind direction, forms the guide face of taper.The taper guide face of alloy wind gathering mouth 6 can effectively be assembled hot blast, and the heat energy utilization rate in the unit of the making cross section improves, and saves energy consumption.Facts have proved that this structure can improve utilization rate of electrical 30% to more than 40%.
In the invention, those skilled in the art can realize air inlet structure to making numerous embodiments.For example, described air inlet structure is arranged on the fresh air inlet 71 on collet 7 inwalls, and the cold wind that fan 3 blows out directly is blown in the cold air duct 8 by fresh air inlet 71.
Further, described air inlet structure is arranged on the ventilation slot 72 of collet 7 ends.Like this, the inwall of collet terminal some and shell 1 is connected or fits, and ventilation slot 72 has then been designed at some position, is used for cold wind and is blown into cold air duct 8.
Further, described air inlet structure is arranged on the wind groove 12 on the shell 1.By the purpose that wind groove 12 also can reach air intake directly is set on the inwall of shell 1.
In addition, for the ease of making and assembling, described housing 1 is fixedly formed by fore shell 13 and back cover 14 combinations.Described fore shell 12 and back cover 14 can be respectively by the mould manufacturings.
As further corrective measure, in the present embodiment, the position that is positioned at fan 4 in the described shell 1 is provided with blimp 9.Combination between blimp 9 and shell 1 and other parts can be accomplished effectively quiet, absorbs fan 4 and the noise that motor 5 sends, and can create good environment for use.As preferably, blimp 4 is that arc is radial, and like this, after it covered on the fan 4, the wind that can effectively fan 4 be blown out was assembled, and guiding wind-tunnel direction further improves utilization rate of electrical.
Certainly, the invention is not limited to above-mentioned embodiment, those of ordinary skill in the art also can make equivalent variations or replacement under the prerequisite of the utility model spirit, modification that these are equal to or replacement all are included in the application's claim institute restricted portion.
