[0010] For the hair dryer according to the embodiment of this application, since the cross-sectional area of the first air outlet is larger than the cross-sectional area of the diversion section of the first air duct, the gas flow velocity at the first air outlet will be smaller than that at the diversion section. And the second air duct communicates with the diversion section of the first air duct.

That is to say, in addition to the air in the first air duct flowing to the first air outlet, the air in the second air duct will also flow to the first air outlet.

In addition, without contradiction, those skilled in the art can combine and combine the different embodiments or examples described in this specification and the features of different embodiments or examples.

[0037] The following is combined with Figures 1 to 4 to describe the hair dryer of the present application.

[0038] According to the embodiments of the present application, asFigure 1 and Figure 2 As shown in Figure 2 , the hair dryer includes a hair dryer body 1. A first air duct 11 is formed inside the hair dryer body 1. The hair dryer body 1 is formed with a first air outlet 12 communicating with the first air duct 11. The hair dryer body 1 is formed with a second air duct 13. The diversion section of the first air duct 11 communicates with the outside through the second air duct 13. Among them, the cross-sectional area of the diversion section is smaller than the cross-sectional area of the first air outlet 12, and / or the cross-sectional area of the diversion section is equal to the cross-sectional area of the first air outlet 12, and the cross-sectional area of the second air duct 13 is smaller than the cross-sectional area of the diversion section.

[0039] For the hair dryer according to the embodiment of the present application, since the cross-sectional area of the first air outlet 12 is larger than the cross-sectional area of the diversion section of the first air duct 11, the gas flow rate at the first air outlet 12 will be smaller than the gas flow rate at the diversion section. And the second air duct 13 communicates with the diversion section of the first air duct 11. Then, under the action of negative pressure, the outside air flow will flow into the first air duct 11 through the second air duct 13, and then flow out together from the first air outlet 12. When the cross-sectional area of the first air outlet 12 is equal to the cross-sectional area of the diversion section, and the cross-sectional area of the second air duct 13 is smaller than the cross-sectional area of the diversion section, when the air flow in the first air duct 11 flows to the first air outlet 12, a negative pressure will be formed between the diversion section and the second air duct 13, so that the outside air flow flows into the first air duct 11 through the third air duct 13, and then flows out together from the first air outlet 12. That is to say, in addition to the gas in the first air duct 11 flowing to the first air outlet 12, the gas in the second air duct 13 also flows to the first air outlet 12. Thus, the air volume at the first air outlet 12 can be effectively increased, that is, the air volume of the hair dryer can be effectively increased, improving the user experience.

[0040] It can be understood that a hair dryer generally includes a motor. The motor is arranged in the first air duct 11 and is adapted to drive the air flow in the first air duct 11 to flow towards the first air outlet 12. The motor 2 can drive the outside gas into the first air duct 11, make the air flow in the first air duct 11 flow towards the first air outlet 12, and finally blow out from the first air outlet 12.

[0041] In an embodiment of the present application, the diversion section is located at the position where the cross-sectional area of the first air duct 11 is the smallest.

[0042] It can be understood that by connecting the position with the smallest cross-sectional area of the first air duct 11 and the outside through the second air duct 13, it is ensured that the gas flow rate at the diversion section is the fastest in the entire first air duct 11, so that a negative pressure can be formed at the second air duct 13, ensuring that the outside gas can flow into the first air duct 11 under the action of negative pressure through the second air duct 13.

[0043] In an embodiment of the present application, from the diversion section to the first air outlet 12, the cross-sectional area of the first air duct 11 gradually increases.

[0044] It can be understood that setting the cross-sectional area of the first air duct 11 corresponding to the diversion section to the first air outlet 12 to gradually increase improves the air outlet area when the gas in the first air duct 11 blows out of the hair dryer body 1, making the user feel more comfortable when using the hair dryer.

[0045] It can be understood that the first air outlet 12 is formed at the end of the first air duct 11, that is, the cross-sectional area of the first air outlet 12 is relatively large, ensuring the air outlet area of the hair dryer.

[0046] It can be understood that setting the cross-sectional area of the first air duct 11 corresponding to the diversion section to the first air outlet 12 to gradually increase makes the flow rate of the gas in the first air duct 11 gradually decrease from the diversion section to the first air outlet 12, thereby ensuring that a negative pressure can be formed at the diversion section, enabling the outside gas to flow into the first air duct 11 through the second air duct 13.

[0047] In an embodiment of the present application, as Figure 1 and Figure 2 shown, a heating module 3 and a motor 2 are provided in the hair dryer body 1. The diversion section is located between the heating module 3 and the first air outlet 12, and the air flow in the first air duct 11 sequentially flows through the motor 2, the heating module 3, and the diversion section.

[0048] It can be understood that the motor 2 drives the gas in the first air duct 11 to flow, so that the air flow in the first air duct 11 sequentially flows through the motor 2, the heating module 3, and the diversion section. When the air flow passes through the heating module 3, the heating module 3 heats the air flow. That is to say, the gas in the first air duct 11 has been heated by the heating module 3 before flowing to the diversion section, increasing the gas temperature at the diversion section, reducing the air pressure at the diversion section, increasing the pressure difference between the outside and the diversion section, and enabling the outside gas to flow into the first air duct 11 through the second air duct 13 more quickly and effectively.

[0049] In an embodiment of the present application, from the heating module 3 to the diversion section, the cross-sectional area of the first air duct 11 gradually decreases.

[0050] It can be understood that ensuring that the cross-sectional area of the first air duct 11 corresponding to the section from the heating module 3 to the diversion section gradually decreases makes the wind speed at the diversion section greater than that at the heating module 3, ensuring that a negative pressure can be formed between the diversion section and the outside, and enabling the outside gas to enter the first air duct 11 through the second air duct 13 under the action of the negative pressure.

[0051] In an embodiment of the present application, as Figure 1 andFigure 2 As shown, the hair dryer body 1 includes a body 14 and a handle 15. The handle 15 is connected to the body 14. A first air outlet 12 is formed at the end of the body 14. The body 14 is formed with a plurality of second air ducts 13, and the air inlets of the second air ducts 13 are arranged on the side wall of the body 14.

[0052] It can be understood that by forming the air inlet of the second air duct 13, that is, the second air inlet, on the side wall of the body 14 and forming the second air duct 13 in the body 14, the length of the second air duct 13 can be shortened.

[0053] In an embodiment of the present application, the first air outlet 12 is an annular air outlet, and the second air ducts 13 are evenly distributed along the circumferential direction of the body 14.

[0054] It can be understood that the outside air enters the first air duct 11 from different second air ducts 13 at the same time, so that the outside air can flow evenly to the first air outlet 12, ensuring the evenness of the air outlet at the first air outlet 12 and avoiding the situation that the air outlet amounts in different regions are different.

[0055] In an embodiment of the present application, as Figure 2 shown, the second air duct 13 gradually inclines towards the first air duct 11 in the direction close to the first air outlet 12.

[0056] It can be understood that by setting the second air duct 13 to gradually incline towards the first air outlet 12, when the air flow in the first air duct 11 flows through the diversion section, the air flow in the first air duct 11 is not likely to flow into the second air duct 13, avoiding the air flow in the first air duct 11 flowing directly to the outside from the second air duct 13, and also avoiding the air flow in the first air duct 11 flowing into the second air duct 13 and affecting the air flow in the second air duct 13 flowing into the first air duct 11, ensuring the air outlet amount of the hair dryer.

[0057] It can be understood that by setting the second air duct 13 to gradually incline towards the first air outlet 12, when the gas in the second air duct 13 flows into the first air duct 11, its flow direction is towards the first air outlet 12. The consistency of the flow direction of the gas in the second air duct 13 flowing into the first air duct 11 and the original air flow direction in the first air duct 11 is improved, which can reduce the mutual influence between the two air flows and ensure the air outlet speed of the hair dryer.

[0058] In an embodiment of the present application, the second air duct 13 is formed in the handle 15, and the second air duct 13 gradually inclines towards the first air duct 11 along the flow direction of the air flow at the diversion section.

[0059] It can be understood that the second air duct 13 is arranged to be gradually inclined along the flow direction of the air flow at the diversion section, so that when the air flow in the first air duct 11 flows to the diversion section, it is difficult to flow into the second air duct 13, ensuring that the air flow in the first air duct 11 can flow normally and will not affect the air flow in the second air duct 13 from flowing into the first air duct 11.

[0060] Moreover, when the air flow in the second air duct 13 flows into the first air duct 11 at the handle 15, the consistency of the flow direction between the air flow flowing from the second air duct 13 into the first air duct 11 and the original air flow in the first air duct 11 can be improved, reducing the mutual influence between the two air flows and ensuring the air outlet speed of the hair dryer.

[0061] In an embodiment of the present application, along the air flow direction of the second air duct 13, the cross-sectional area of the second air duct 13 gradually decreases.

[0062] It can be understood that the cross-sectional area of the second air duct 13 is set to be smaller the closer it is to the diversion section, so that the gas flow rate is faster from the second air inlet to the diversion section, ensuring that the gas flow rate at the diversion section is fast enough, increasing the pressure difference between the outside and the second air duct 13, and enabling the outside air to flow more quickly into the first air duct 11 through the second air duct 13, ensuring the air output of the hair dryer.

[0063] In an embodiment of the present application, as Figure 2 shown, the hair dryer body 1 is formed with an air outlet hole 16, the air outlet hole 16 and the first air outlet 12 are formed on the same end face, the air outlet hole 16 is communicated with the first air duct 11 through a communication channel, and the connection part of the communication channel and the first air duct 11 is located between the diversion section and the first air outlet 12.

[0064] It can be understood that when the hair dryer is working, the motor 2 drives the gas flow in the first air duct 11. When the gas flow in the first air duct 11 flows to the diversion section, the outside gas will flow into the first air duct 11 through the second air duct 13 and mix with the original gas in the first air duct 11. The mixed gas continues to flow towards the first air outlet 12. When the mixed gas flows through the connection part of the communication channel and the first air duct 11, a part of the mixed gas will flow into the communication channel, that is, a part of the mixed gas will flow out from the air outlet hole 16 through the communication channel, and the other part will continue to flow out from the first air outlet 12 along the first air duct 11, thereby increasing the air outlet area of the hair dryer, and by diverting the gas between the diversion section and the first air outlet 12 through the communication channel, the gas flow rate between the diversion section and the first air outlet can be reduced.

[0065] It can be understood that when the air flow in the first air duct 11 flows out through the first air outlet 12, since the first air outlet 12 and the air outlet holes 16 are formed on the same end face, under the influence of the air flow at the first air outlet 12, the air flow velocity at the air outlet holes 16 will also increase, thereby promoting the gas in the first air duct 11 to flow into the communication channel.

[0066] In an embodiment of the present application, as Figure 3 and Figure 4 shown, a third air inlet 17 is formed on the outer wall surface of the hair dryer body 1. The third air inlet 17 is communicated with a third air outlet 19 through a third air duct 18, and the third air outlet 19 and the first air outlet 12 are formed at the same end of the hair dryer body 1.

[0067] According to the hair dryer of the embodiment of the present application, the motor 2 can drive the outside gas into the first air duct 11, and make the air flow in the first air duct 11 flow towards the first air outlet 12 and finally blow out from the first air outlet 12. Since the third air outlet 19 and the first air outlet 12 are formed at the same end of the hair dryer body, when the gas in the first air duct 11 blows out from the first air outlet 12, it will drive the gas flow at the third air outlet 19, increase the gas flow velocity at the third air outlet 19, and form a pressure difference between the third air inlet 17 and the third air outlet 19. The outside gas will flow into the third air duct 18 under the action of negative pressure and finally blow out from the third air outlet 19. That is, when the hair dryer of the present application is in use, the first air outlet 12 and the third air outlet 19 blow air towards the user at the same time, increasing the air outlet area of the hair dryer and effectively increasing the air volume of the hair dryer.

[0068] In an embodiment of the present application, the third air outlet 19 and the first air outlet 12 are formed on the same end face.

[0069] It can be understood that forming the third air outlet 19 and the first air outlet 12 on the same end face enables the wind at the first air outlet 12 to fully drive the gas flow at the first air outlet 12, ensuring that a pressure difference can be formed between the third air inlet 17 and the third air outlet 19, and the outside gas can flow into the third air outlet 19 through the third air duct 18.

[0070] In an embodiment of the present application, as Figure 4 shown, along the direction from the third air inlet 17 to the third air outlet 19, the cross-sectional area of the third air duct 18 gradually decreases.

[0071] It can be understood that the cross-sectional area of the third air duct 18 is set to be smaller closer to the third air outlet 19, so that the gas flow rate in the third air duct 18 is larger closer to the third air outlet 19, ensuring that the gas flow rate at the third air outlet 19 is always greater than that at the third air inlet 17. This guarantees that there is a pressure difference between the third air outlet 19 and the third air inlet 17 during the use of the hair dryer, and the external gas can continuously flow through the third air duct 18 to the third air outlet 19.

[0072] In an embodiment of the present application, as Figure 4 shown, the third air duct 18 gradually inclines towards the third air outlet 19 in the direction close to the first air outlet 12.

[0073] It can be understood that setting the third air duct 18 to gradually incline towards the first air outlet 12 improves the consistency of the flow direction of the gas in the third air duct 18 when blowing out through the third air outlet 19 with the flow direction of the air flow at the first air outlet 12, avoiding the mutual influence between the air flow at the third air outlet 19 and the gas at the first air outlet 12, and ensuring the speed of the gas blown out by the hair dryer.

[0074] In an embodiment of the present application, as Figure 4 shown, the air outlet direction of the third air outlet 19 is the same as the air outlet direction of the first air outlet 12.

[0075] It can be understood that setting the orientation of the third air outlet 19 and the orientation of the first air outlet 12 to be the same makes the flow directions of the gas blown out through the first air outlet 12 and the gas blown out through the third air outlet 19 basically the same, avoiding the mutual influence between the gas at the first air outlet 12 and the gas at the third air outlet 19, which may cause a decrease in the wind speed of the hair dryer.

[0076] In an embodiment of the present application, the third air outlet 19 faces the first air outlet 12.

[0077] It can be understood that setting the third air outlet 19 to face the first air outlet 12 causes the wind blown out from the third air outlet 19 to converge with the wind blown out from the first air outlet 12. And there is a heating module 3 in the hair dryer body 1, and the wind in the first air duct 11 will be heated by the heating module 3 first and then blown out from the first air outlet 12. Thus, in the present application, the wind blown out from the third air outlet 19 converges with the hot wind at the first air outlet 12, avoiding uneven hot and cold of the wind blown to the user.

[0078] In an embodiment of the present application, as Figure 4 shown, the first air outlet 12 is an annular air outlet, and the annular air outlet is arranged around the third air outlet 19.

[0079] It can be understood that the first air outlet 12 surrounds the third air outlet 19, so that the air blown out from the third air outlet 19 can fill the air volume at the center of the first air outlet 12. While increasing the air volume of the hair dryer, the air outlet area of the hair dryer can be effectively increased.

[0080] In an embodiment of the present application, a heating element is provided in the third air duct 18, and the heating element is adapted to heat the gas in the third air duct 18.

[0081] It can be understood that the gas in the third air duct 18 can be heated by the heating element, so that the gas blown out through the third air outlet 19 also has a certain temperature instead of being at room temperature. And by adjusting the heating element, the air outlet temperature at the third air outlet 19 can be made the same as the air outlet temperature at the first air outlet 12, avoiding blowing two different temperatures of air to the user and improving the user experience.

[0082] It can be understood that by heating the gas in the third air duct 18 with the heating element, the temperature of the gas in the third air duct 18 rises, causing the gas pressure in the third air duct 18 to decrease, forming a pressure difference between the outside and the third air duct 18, which can promote the flow of outside gas into the third air duct 18 and ensure the air volume at the third air outlet 19.

[0083] In an embodiment of the present application, as Figure 4 shown, the hair dryer body 1 includes a body 14 and a handle 15. The handle 15 is connected to the body 14, and the body 14 is formed with a plurality of third air ducts 18. The third air inlet 17 is provided on the side wall of the body 14.

[0084] It can be understood that both the third air duct 18 and the third air inlet 17 are located in the body 14, which can shorten the length of the third air duct 18.

[0085] In an embodiment of the present application, as Figure 4 shown, a plurality of third air inlets 17 are evenly distributed along the circumferential direction of the body 14.

[0086] It can be understood that by evenly arranging a plurality of third air inlets 17 on the outer wall surface of the body 14, the outside gas can flow to the third air outlet 19 through different third air inlets 17 and be blown out, increasing the air intake volume of the hair dryer and ensuring the air volume of the hair dryer.

[0087] In an embodiment of the present application, as Figure 4 shown, the handle 15 is provided with a first air inlet 151 communicating with the first air duct 11.

[0088] It can be understood that when the motor 2 is working, the outside air enters the first air duct 11 through the first air inlet 151, and then, driven by the motor 2, the air flow in the first air duct 11 flows towards the first air outlet 12.

[0089] Finally, it should be noted that the above embodiments are only used to illustrate the present application, rather than to limit the present application. Although the present application has been described in detail with reference to the embodiments, those of ordinary skill in the art should understand that various combinations, modifications or equivalent replacements of the technical solutions of the present application do not depart from the spirit and scope of the technical solutions of the present application, and should all be covered by the scope of the claims of the present application.
