[0032] Reference Figures 1 to 10 In an embodiment of the present application, a main body 200 of a hair dryer 1000 and a functional head 100 that can be detachably or fixedly installed on the main body 200 are provided. The functional head 100 includes a main body 10 and an air guide 20. An air inlet 11 of a first flow direction and an air outlet 12 of a second flow direction are constructed in the main body 10. The air inlet 11 and the air outlet 12 are connected and arranged at an angle. For example, in this embodiment, an air inlet is provided at the lower end of the main body 10, and an air outlet is provided on one side of the upper end, so that an air inlet 11 extending vertically upward (first flow direction) is formed at the lower end inside the main body 10, and an air outlet 12 extending horizontally (second flow direction) is formed at the upper end inside the main body 10. Furthermore, in order to facilitate the airflow in the air inlet duct 11 to flow more smoothly to the air outlet duct 12, the air guide member 20 includes an air outlet end portion 21 and an air guide portion 22, the air outlet end portion 21 covers the air outlet port of the air outlet duct 12, and is provided with a plurality of air outlet holes 211, the large diameter end 221 of the air guide portion 22 is connected to the inner surface of the air outlet end portion 21, the small diameter end 222 is located in the air outlet duct 12 and extends to the junction of the air inlet channel and the air outlet channel, so that an air collecting duct 30 is formed between the small diameter end 222 and the large diameter end 221 and the inner wall of the air outlet duct 12, and the air guiding cross-sectional area of ​​the air collecting duct 30 gradually decreases from the small diameter end 222 toward the large diameter end 221; the air flow flowing into the air inlet duct 11 is blocked by the air outlet end portion 21 after passing through the air collecting duct 30, and is discharged to the outside through the plurality of air outlet holes 211.

[0033] Specifically, Figure 4 As shown, in the embodiment of the present application, the multiple air outlet holes 211 provided at the air outlet end 21 are arranged at intervals around the air guide portion 22 and are in the shape of long strips, so that the airflow discharged from the air collecting duct 30 is evenly discharged to the outside along the multiple air outlet holes 211 circumferentially of the air guide portion 22.

[0034] Specifically, Figure 1 , Figure 3 Combination Figure 7 As shown, in the embodiment of the present application, the outer diameter from the large diameter end 221 to the small diameter end 222 gradually decreases, so that the connecting side wall 223 between the large diameter end 221 and the small diameter end 222 is inclined, so that the air guide cross-sectional area of ​​the air collecting channel 30 formed between the large diameter end 221 and the inner wall of the main body 10 gradually decreases, and the airflow is converged. At the same time, in order to prevent the large inclination angle, the difference between the outer diameters of the large diameter end 221 and the small diameter end 222 is large, resulting in a large change in the air guide cross-sectional area, and more airflows are gathered at the air outlet 211 in a short time, resulting in noise. At the same time, to avoid a small inclination angle, the difference between the outer diameters of the small diameter end 222 and the large diameter end 221 is small. Although the airflow is relatively smooth and the noise is small when it converges and is compressed through the long air collecting channel 30, the air inlet side of the air collecting channel 30 is relatively small, and the airflow conduction area of ​​the air inlet 11 is greatly different, resulting in a relatively unsmooth phenomenon when the airflow enters the air collecting channel 30 from the air inlet 11. In the embodiment of the present application, the value range of the inclination angle α is: 15°≤α≤45°. For example, the angles are 15°20°, 25°, 30°, 40°, 45°, etc. In the embodiment of the present application, the value of α is 25°, so that the airflow can flow smoothly into the air gathering duct 30, and flow out through multiple air outlets 211 after a relatively gentle convergence and compression process. And the difference in outer diameter between the small diameter end 222 and the large diameter end 221 is relatively small, so that a larger installation space can be set inside the air guide part 22 to form an installation cavity 224 for the installation of the functional board 2241, and the functional board 2241 can be equipped with one or more lighting circuits, temperature measurement circuits, and temperature control circuits.

[0035] It can be understood that, in actual use, the air guide portion 22 can be in the shape of a truncated cone or an elliptical cone, or a cone with a runway-shaped cross-section. When the air guide portion 22 is in the shape of a truncated cone, the inclination angle α of the connecting side wall 223 between the large diameter end 221 and the small diameter end 222 is consistent. When it is in the shape of an elliptical cone or a runway-shaped cone, the inclination angles α1 and α2 of each connecting side wall 223 are different, but are all within the value range of [15°, 45°].

[0036] Furthermore, if Figure 1 As shown, in the embodiment of the present application, an air guiding arc surface 40 is constructed at the intersection of the air inlet duct 11 and the air outlet duct 12, and the air inlet side of the air guiding arc surface 40 corresponds to the air inlet duct 11, and the air outlet side corresponds to the air gathering duct 30, so as to guide the airflow to the air gathering duct 30. Here, by constructing the air guiding arc surface 40, the airflow is guided more smoothly, and the airflow is prevented from being blocked by the inner wall structure of the air outlet duct 12 when flowing from the air inlet duct 11 to the air outlet duct 12, and directly flowing in the opposite direction and colliding, resulting in the phenomenon of airflow turbulence.

[0037] Furthermore, if Figure 1 As shown, the airflow enters the air gathering duct 30 and flows more smoothly. In the embodiment of the present application, the diameter of one end of the air outlet duct 12 connected to the air inlet duct is smaller than the diameter of the air outlet port, so that the inner wall of the air outlet duct 12 is inclined and has a gradually widened design. Here, the surfaces constituting the air gathering duct 30 are all inclined, so that the airflow can converge toward the air outlet along the side wall of the air guide 22 and the inner wall of the air outlet duct 12. At the same time, the relationship between the inclination angle value β is: α>β. In the embodiment of the present application, the value of the bevel angle β is 15°. Therefore, the side wall of the air outlet channel is not parallel to the side wall of the air guide 22, and the cross-sectional area of ​​the air gathering duct 30 formed between the two gradually decreases with the gas flow direction. When there are differences in the inclination angles of the side walls of the air guide 22, the difference between the inclination angles β and α of the side walls constituting the air gathering duct is close to the same, and the relationship is: α-β=10°, so that the air guide area formed on each surface is close to the same, making the airflow more stable.

[0038] Specifically, Figure 1 As shown, in the embodiment of the present application, part of the air collecting duct 30 corresponding to the air outlet side of the air guiding arc surface 40 has more airflow. In order to reduce the difference in the overall airflow of the air collecting duct 30, the small diameter end 222 protrudes to a position located at one quarter to one half of the cross-section of the air inlet duct 11, so that part of the airflow in the air inlet duct 11 is obstructed by the small diameter end 222 and diverted. Part of it flows along the side wall of the small diameter end 222 into the air collecting duct 30, and part of it flows to the air guiding arc surface 40 and then flows into the air collecting duct 30 along the air outlet side of the air guiding arc surface 40, so that the airflow of each air outlet hole 211 is relatively uniform.

[0039] Furthermore, in order to better divert the gas, as Figure 1 Combination Figure 8 As shown, in the embodiment of the present application, the inner wall of the air inlet duct 11 is also provided with an airflow separation boss 50 toward the end surface of the small diameter end 222, and the airflow separation boss 50 is connected to the end surface of the small diameter end 222, so that the airflow flowing in from the air inlet duct 11 is divided along the two sides of the airflow separation boss 50, so that the airflow flowing into the air collection duct 30 around the air guide portion is more uniform. At the same time, the airflow separation boss 50 is connected to the air guide portion to enhance the connection stability of the air guide portion, and avoid the air guide portion being connected to the main body 10 only through the air outlet end 21. When used for a long time, the high-speed airflow continuously impacts the air guide portion 22, and the air outlet end 21 and the main body 10 become loose.

[0040] Specifically, Figure 7As shown, in the embodiment of the present application, the edge of the small diameter end 222 is provided with an arc chamfer 2221, one end of the arc chamfer 2221 is adjacent to the connection with the airflow separation boss 50, and the other end is connected to the side wall of the air guide portion 22 that constructs the air gathering duct 30, so that part of the airflow blocked by the airflow separation boss 50 flows along the arc chamfer 2221 toward the air gathering duct 30.

[0041] In order to better achieve the above goals, Fig. 9 Combination Fig.10 As shown, the present application also provides a hair dryer 1000, including a main unit 200 and a functional head 100 as described above. Since the hair dryer 1000 includes all the technical solutions of the functional head 100, it has all the beneficial effects of the technical solutions, which will not be repeated here. The main unit 200 is provided with an air supply duct 210, an air flow traction component 220 and a control component 230. The functional head 100 is installed on the main unit 200, and the air inlet duct 11 of the functional head 100 is connected to the air supply duct 210. Under the control of the control component 230, the air flow traction component 220 draws the external air flow from the air inlet hole 240 at the lower end of the main unit 200 to the air supply duct 210 and then flows into the air inlet duct 11. The air flow traction component 220 is a high-speed fan.

Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention.
