Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-3 of the specification, an embodiment of the present invention provides a high-wind-power low-noise side-inlet air blower, which includes a casing composed of a left casing 110 and a right casing 120 with a handle, an inner air duct 610 disposed along an axial direction of the casing is disposed in the casing, an air inlet end of the inner air duct 610 extends to a rear side of the casing to form a semicircular motor bracket, a brushless dc motor assembly 700 with a fan is fixed in the motor bracket, and a fixing cover 620 is disposed on a side cover of a mounting opening of the motor bracket to fix the brushless dc motor assembly 700 on the motor bracket.

The left outer shell 110 and the right outer shell 120 are provided with annular air inlets, the axial directions of the annular air inlets are orthogonal to the axial direction of the inner air duct 610, and the outer sides of the annular air inlets are sequentially provided with air inlet iron nets (111, 121) and air inlet covers (112, 122), the air inlet iron nets (111, 121) can filter sundries, the air inlet covers (112, 122) can rotate when sucking air to increase the air inlet amount, and a large air amount providing basis is provided for the hair dryer.

When the brushless direct current motor assembly 700 is driven, external air is adsorbed in the housing from the annular air inlets on both sides, and because the annular air inlets are orthogonal to the brushless direct current motor assembly 700, the motor support and the fixed cover 620 wrap the peripheral side of the brushless direct current motor assembly 700 at the same time, so that air entering the housing needs to flow into the motor by bypassing the rear end of the motor support, and wind noise generated when the motor directly sucks air volume is effectively reduced.

In the present embodiment, the motor in the brushless dc motor assembly 700 is an ultra-high speed brushless motor with a diameter of 40mm, and the speed of the motor reaches 98000 rpm, which can provide a larger wind speed/wind volume compared to the low speed and large motor used in the conventional hair dryer products in the existing market.

In this embodiment, a heating rack 800 is disposed at the air duct portion of the inner air duct 610, a wave heating wire is wound on the heating rack 800, a front tube 130 is sleeved outside the inner air duct 610, and the rear end of the front tube 130 is connected with the housing in a fastening manner. From this, the air blows the frame 800 that generates heat in to interior dryer 610 after the motor pressure boost, and the wave heater heats the air through interior dryer 610, forms the high-speed air current that has the uniform temperature, can dry fast the hair.

In addition, in this embodiment, the motor mounting position of the brushless dc motor assembly 700 is disposed at a side close to the heat generating frame 800, which can reduce the meandering flow of the air flowing process to the maximum extent, so that the blown air flow channel is smoother and the wind power is larger.

In this embodiment, the FND display screen 200 and the motor driving board 300 are disposed inside the center of the annular air inlet of the left casing 110, the key board 500 is disposed at the rear side of the casing, the control board 400 is disposed inside the handle portion of the casing, the wind speed key, the heat key and the power key are disposed on the key board 500, and the control board 400 is electrically connected to the FND display screen 200, the motor driving board 300 and the key board 500. Control panel 400 can realize the intelligent thermostatic control to wave heater, and the user can select suitable heat and wind speed as required, makes the user when drying the hair fast, also can not damage the hair because of overheated.

Moreover, in the embodiment, the negative ion generator (not shown) is arranged in the shell, so that the user can quickly blow and dry hair in the operation process and continuously release negative ions to moisten and maintain the hair in the use process, and the hair is quickly blown and dried without generating fatigue.

A protective cover 113 is provided outside the center of the circular inlet of the left housing 110, and a protective cover 123 is provided outside the center of the circular inlet of the right housing 120 to keep the blower symmetrical as a whole.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
