BACKGROUND

Hair dryer is composed of a group of electric heating wires and a high-speed fan. When the electric heating wires is powered on, it will generate heat, the airflow blown out by the fan will become hot after passing through the electric heating wires.

As an example, the housing 203 of the main body 201 is in the shape of long cylinder, the blowing port 2012 can be opened at one end of the housing, the housing can have a straight air channel, the hair dryer can provide a larger air volume and wind force under a certain power.

The housing 203 can also have an inlet, the inlet and the blowing port 2012 can be respectively arranged at both ends of the housing 203. The circuit board, the motor and the heating element can be arranged in the housing 203. The circuit board can be etched with a circuit for controlling the operation of the motor and the heating element, and the circuit board can be used for controlling the operation of the hair dryer 200. The motor can be used to be driven to generate airflow, and the airflow can be blown out from the hair dryer 200. The heating element can be a heating wire, which may be arranged at one end of the housing 203 close to the blowing port 2012, the heating element can be used to heat the airflow, so that hot airflow can be blown out from the hair dryer 200. When the hair dryer 200 is used, the motor and the heating element can be controlled to start by the circuit board, the air can be sucked into the housing 203 through the inlet to generate an airflow, the airflow can be heated by the heating element and entered the outlet assembly 100 through the blowing port 2012, and blown out from the outlet assembly 100 to dry hair.

Referring to FIG. 2 and FIG. 3, the outlet assembly 100 can include a outlet head 10, a first adjusting element 30, a second adjusting element 40 and an operating element 50. The outlet head 10 can be provided with an air channel 11 passed through the outlet head 10, an air inlet 12 and an air outlet 13 are formed at both ends of the outlet head 10, the air channel 11 can be communicated with the blowing port 2012 through the air inlet 12. The first adjusting element 30 and the second adjusting element 40 can be arranged in parallel in the air channel 11, and can be rotatably connected to the outlet head 10.

When user uses the hair dryer 200, the airflow can be entered the air channel 11 from the blowing port 2012, and can be blown out through the air outlet 13 to dry hair. At this time, the second side 34 and the fourth side 43 can be fitted to inner wall of the outlet head 10 to increase diameter of the outlet.

When the user needs to change the airflow pattern, the first adjusting element 30 and the second adjusting element 40 can be moved towards to each other relative to the outlet head 10 by controlling the operating element 50, so that the second side 34 and the fourth side 43 can be located at different positions of the air outlet 13, at this time, the airflow can be blown between the first adjusting element 30 and the second adjusting element 40. The first adjusting element 30 and the second adjusting element 40 can not be fitted with the inner wall of the outlet head 10, when the high-speed airflow is passed through the first adjusting element 30 and the second adjusting element 40, the noise emitted by the vibration of the first adjusting element 30 and the second adjusting element 40 will not be directly transmitted to the outside under the barrier of the side wall of the outlet head 10, which can reduce the generated noise.

In one embodiment, the outlet head 10 can include an air collecting part 14 and a molding part 15, the air collecting part 14 can be connected between the molding part 15 and the housing 203. The air channel 11 can be run through the air collecting part 14 and the molding part 15 successively. One end of the air collecting part 14 facing the housing 203 can be connected to the blowing port 2012 of the housing 203. The housing 203 and the air collecting part 14 can be connected by structural adhesive bonding, or by fasteners.

The molding part 15 can also be hollow and be connected to the air collecting part 14. One end of the molding part 15 can be connected to the air collecting part 14, so that the air channel 11 defined by the molding part 15 and the air collecting part 14 can be communicated. The air outlet 13 can be arranged at one end of the molding part 15 away from the air collecting part 14, the first adjusting element 30 and the second adjusting element 40 can be arranged in the air channel defined by the molding part 15.

In this embodiment, the cross section shapes of the molding part 15 and the air collecting part 14 are different.

In an embodiment, the cross-section of at least part of the structure of the air collecting part 14 can be circular, for example, the end of the air collecting part 14 connected to the housing 203 can be cylindrical to facilitate connection with the cylindrical housing 203. The air collecting part 14 can be a cylindrical shell as a whole. In the direction from the air inlet 12 to the air outlet 13, the inner diameter of the air collecting part 14 can be gradually reduced, so that the airflow from the blowing port 2012 can be concentrated into the molding part 15, and the force of the airflow in the molding part 15 can be increased. Specifically, the air collecting part 14 can be in the shape of a circular funnel with a gradually decreasing inner diameter. If the air collecting part 14 is nested with the housing 203, the outer diameter of the end of the air collecting part 14 near the housing 203 can be less than the outer diameter of the other outer walls, so the air collecting part can be embedded into the blowing port 2012, and the outer wall adjacent to the end of the blowing port 2012 can be smoothly connected to the outer wall of the housing 203.

The third side wall 1543 can be bent away from the air channel 11 to form a curved side wall, and the fourth side wall 1547 can also be bent away from the air channel 11 to form a curved side wall, which increases the cross sectional area of the air channel 11. The specific direction of the first direction wall Y and the second direction X are not limited in the present disclosure, for example, the first direction Y can be the thickness direction of molding part 15, and the second direction X can be the width direction of molding part 15, the first direction Y can be parallel to a diameter of the air collecting part 14. In another embodiment, the first direction Y is the width direction of the molding part 15, and the second direction X is the thickness direction of the molding part 15.

The first side wall 1541, the third side wall 1543, the second side wall 1545 and the fourth side wall 1547 can be successively connected to define the air outlet 13 and part of the air channel 11. In order to meet the precise styling of the user's hair, increase the outlet density and wind speed, the air outlet 13 can be in shape of a flat rectangle or an oval.
