Referring to FIG. 4 and FIG. 5 , it shows an embodiment of the adjustable wind direction hair dryer 1 of the present invention. In this embodiment, the adjustable wind direction blower 1 includes a casing 20, fan blades 30, a main motor 40, a motor frame 50, a heating component 60, a control circuit board (not shown in the figure) and a wind direction adjusting device 10 (as shown in the figure). 1). Among them, the casing 20 is composed of a left casing (not shown), a right casing 220, a rear cover 230, a rear casing cover 240 and a handle 250; The circuit board (not shown) and the driving assembly 130 are all placed in the casing 20, the driving assembly 130 is controlled by the control circuit board, and the head cover 110 is installed on the air outlet of the casing 20 place. Preferably, the head cover 110 is mounted on the air outlet of the casing 20 in a snap-fit manner and can rotate 360° relative to the casing 20 , as shown in FIGS. 9 a to 9 c . The main improvement of the adjustable wind direction hair dryer 1 of this embodiment lies in its wind direction adjusting device 10 , and the specific structures and principles of other parts are well known to those skilled in the art, and will not be repeated here.

Referring to Fig. 5 to Fig. 9c, the working principle of the adjustable wind direction hair dryer 1 of this embodiment will be briefly explained below.

The operating principle of wind direction adjusting device 10 is as follows:

When the swing drive motor 133 rotated forward, the screw shaft 132 also rotated forward, thereby impelling the rotating ring 131 to rotate forward. When the bottom of the opening 1313 is in contact), the rotating ring 131 no longer moves forward. At this time, the protruding shaft 1312 on it stretches into the elliptical groove 1223 of the swing arm 122, and performs circular motion in the elliptical groove 1223. because the groove 1223 on the swing arm 122 is elliptical, and the locus of motion of the protruding shaft 1312 of the rotating ring 131 is a perfect circle, therefore, in this process, under the promotion of the protruding shaft 1312, both sides of the swing arm 122 swing ( move back and forth along its length direction), and the window blade 121 is rotatably installed on the installation frame 112, and it also swings up and down relative to the installation frame 112 under the drive of the swing arm 122 (also along the length direction of the swing arm 122 back and forth), as shown in Figures 6a to 7c.

When the swing driving motor 133 rotates in the opposite direction, the screw shaft 132 drives the rotating ring 131 to turn back to the second position (the rotating ring 131 is in contact with the limit ring), at this time, the protruding shaft 1312 of the rotating ring 131 leaves the swing arm 122 The elliptical groove 1223, the rotating ring 131 no longer exerts force on the swing arm 122. At this time, under the action of the two slingshots 123 and 124 on the mounting bracket 112, the swing arm 122 is corrected to the initial state, as shown in Figures 8a to 8c As shown, the window blade 121 stays in a flat position, and the wind direction goes straight out, which is no different from an ordinary hair dryer.

The above-mentioned working process of the wind direction adjusting device 10 can be manually controlled by the control button on the blower 1, and can also be set by a program, such as controlling the polarity of the power supply of the swing drive motor 133, so that when the swing drive motor 133 rotates in the forward direction, when does it rotate forward? How long, when to reverse, how long to reverse, when to stop working, how long to stop, etc. The process can be automatically controlled by setting the program.

Hair dryer 1 working instructions are as follows:

The main motor 40 will rotate after the power is turned on, and the rotation of the main motor 40 will drive the fan blades 30 to rotate. Assembly 60 finally passes through the air outlet in front of the casing 20, and when it reaches the position of window blade 121, the passing wind is also swinging to the two poles because the window blade 121 is pushed by the two poles of the swing arm 122 and blows out; on the other hand, because the window blade assembly 120 is set on the head cover 110, and the head cover 110 can be manually rotated 360 degrees. Therefore, when the head cover 110 is manually rotated in which direction, the window blades 121 will swing on both sides of the direction, thereby realizing the multi-angle of wind direction. Adjustment, as shown in Figure 9a to Figure 9c.

As mentioned above, when the wind direction adjustment device provided by the utility model is used in a hair dryer, the swing of the window blades can be controlled by controlling the working state of the drive assembly, thereby controlling the air outlet direction of the hair dryer and realizing the effect of adjustable wind direction; Based on the adjustable wind direction function, when using hot air to blow hair, the heat will not gather at the same location and cause the hair and scalp to overheat, avoiding damage to the hair quality and scalp, and bringing a good user experience. In the same way, the adjustable wind direction hair dryer provided by the utility model has the above-mentioned wind direction adjustment device, thus has a corresponding wind direction adjustment function, and also has the above-mentioned advantages.

The utility model has been described above in conjunction with the best embodiments, but the utility model is not limited to the above-disclosed embodiments, but should cover various modifications and equivalent combinations based on the essence of the utility model.
