[0035] Further, the handle air duct 22 is provided with a fan 23. The fan 23 can drive air to enter from the air inlet 21, flow to the air outlet 11 through the handle air duct 22 and the main body air duct, and then be blown out to the front through the air outlet 11.

[0036] Reference Figure 3In the embodiment, the handle air duct 22 is designed as a trumpet air duct that gradually expands without narrowing towards the main body part, which can slow down the airflow speed, so that the fluid in the handle air duct 22 flows smoothly to the air guide support 12, reducing noise.

[0037] Specifically, in the prior art, the connection area between the handle air duct and the annular air duct of the main body part usually has a sudden narrowing change in cross section, which will cause the airflow speed to suddenly increase, generating aerodynamic noise. In the embodiment, the handle 20 includes a sleeve 201 and a handle main body 202 arranged inside the sleeve 201, the air blower 23 is arranged in the handle main body 202, and the handle main body 202 is gradually expanded in the area between the air outlet of the air blower 23 and the main body part 10, thereby forming a trumpet air duct that directly expands without narrowing.

[0038] The main body part 10 is provided with an air guide support 12 relative to the air outlet 11, the air guide support 12 is arranged at the air outlet position of the handle air duct 22, and the air outlet of the handle air duct 22 enters the main body air duct through the air guide support 12.

[0039] Specifically, the main body air duct includes a circuit board cooling air duct 101 at the rear end of the main body part 10, a central air duct 102 separated from the circuit board cooling air duct 101 by the air guide support 12, and an annular air duct 103 arranged around the central air duct 102.

At the same time, the top end of the annular air guide strip 121 is provided with a baffle 123 extending in the direction of the air outlet 11, which can contact and guide the air flowing along both sides of the annular air guide strip 121 to the air outlet 11 through the baffle 123, ensuring smooth air intake and reducing noise caused by airflow collision.

[0042] Further, reference Figure 2In the embodiment, the air guide support 12 is arranged obliquely relative to the handle air duct 22, and the air guide support 12 is arranged obliquely with the top thereof facing the direction of the air outlet 11, and the oblique direction is such that the air guide support 12 is arranged obliquely in the direction in which the air duct travels and faces the air outlet 11.

At the same time, the air guide support 12 arranged obliquely can guide the airflow to flow along the oblique surface of the air guide support 12 smoothly, and the airflow is turned stably after being gathered at the top of the air guide support 12, thereby reducing the generation of noise.

[0043] Reference Figure 2 In the embodiment, the air outlet 11 includes a central air outlet 111 located at the middle of the front end of the main body 10, and an annular air outlet 112 arranged around the central air outlet 111.

[0044] The annular air duct 103 is arranged relative to the annular air outlet 112, and air can be driven by the fan 23 to enter the air inlet 21, pass through the handle air duct 22, be guided by the air guide support 12 to the annular air duct 103, flow to the annular air outlet 112, and be blown out forwardly by the annular air outlet 112.

[0045] The central air duct 102 is arranged between the air guide support 12 and the air outlet 11, and the ion assembly 13 is arranged in the central air duct. The air guide support 12 is provided with an air inlet through hole 124 which connects the circuit board cooling air duct 101 and the central air duct 102.

[0046] The circuit board cooling air duct 101 includes a circuit board chamber 14 arranged in the air outlet direction of the handle air duct 22, and the circuit board chamber 14 is located at the end of the main body 10 away from the air outlet 11. The control circuit board 15 is arranged in the circuit board chamber 14. At the same time, the end of the main body 10 away from the air outlet 11 is provided with a cover shell 141, and the cover shell 141 and the air guide support 12 correspondingly form the circuit board chamber 14. The control circuit board 15 can be correspondingly arranged in the circuit board chamber 14 and located at the rear end of the main body 10 away from the air outlet 11, so that the structure of the main body is more compact.

[0047] In the embodiment, a through hole (not shown in the figure) is arranged below the bottom end position of the annular air guide strip 121 in the air guide support 12. The air flowing out of the handle air duct 22 can enter the circuit board cooling air duct 101 through the through hole and flow into the circuit board cavity 14 as circuit cooling air to cool the circuit elements in the control circuit board 15. The circuit cooling air in the circuit board cooling air duct 101 can flow into the central air duct 102 through the air inlet through hole 124 and carry the ions generated by the ion assembly 13 and be blown out through the central air outlet 111.

[0048] In the embodiment, the air flow to the ion assembly 13 is controlled to be greater than or equal to 0.02 m3 / min by arranging the air inlet through hole 124, so as to ensure the ion air outlet flow.

[0049] The main body part 10 is provided with a heater support 16 arranged between the air guide support 12 and the air outlet 11. The annular air duct 103 is further provided with a heating assembly 161 arranged outside the heater support 16. Specifically, the heating assembly 161 is used to heat the air flowing therethrough. The air fan 23 drives the air to enter through the air inlet 21, and then the air is guided to the annular air duct 103 through the handle air duct 22 and the air guide support 12. After being heated by the heating assembly 161, the air forms hot air and is blown out through the annular air outlet 112.

[0050] The heater support 16 is internally provided with a high-voltage generator 17 connected with the ion assembly 13. Specifically, the high-voltage generator 17 is connected with the control circuit board 15 in the circuit board cavity 14, and the high-voltage generator 17 can control the ion assembly 13 to generate ions. At the same time, the high-voltage generator 17 is arranged inside the heater support 16, so that the structure of the main body part is more compact.

[0051] Further, referring to Figure 2 , after the high-voltage generator 17 is installed, it is located behind the ion assembly 13 and in the central air duct 102. During the process that the circuit cooling air in the circuit board cooling air duct 101 enters the central air duct 102 through the air inlet through hole 124 and flows to the central air outlet 111, the circuit cooling air can take away the heat around the ion assembly 13 and the heat of the high-voltage generator 17, and help the ions generated by the ion assembly 13 to be quickly blown out through the central air outlet 111, thereby improving the utilization efficiency of the air.

[0052] The heater support 16 is further internally provided with an ion support 18, and the ion assembly 13 is installed in the ion support 18. Specifically, the ion assembly 13 is installed in the ion support 18, and the ion support 18 is arranged inside the heater support 16 and makes the ion assembly 13 correspondingly arranged in the central air duct 102, so that the ion assembly 13 can stably provide ions in the central air duct 102 while making the structure of the main body part more compact.

[0053] Further, referring to Figure 4 , the central air duct where the ion assembly 13 is located is also the center of the annular air duct where the heating assembly 161 is located, which can effectively reduce the radial size of the main body part, so that the main body part structure is more compact.

[0054] Referring to Figure 4 , in this embodiment, the number of ion assemblies 13 is set to two, and the number of ion assemblies 13 can be adjusted according to actual assembly requirements.

[0055] In this embodiment, the ion assembly 13 includes a water ion generator and / or a negative ion generator.

[0056] Preferably, the ion assembly 13 is a negative ion generator, which includes but is not limited to a mineral ion generator and a metal ion generator. The type of ion assembly 13 can be adjusted according to actual design and use requirements, which is not limited here.

[0057] The main body part 10 also has an air outlet cover 19, which is matched with the air outlet 11. Specifically, the air outlet cover 19 has air outlet gaps corresponding to the annular air outlet 112 and the central air outlet 111. The air flow can be constrained by the air outlet cover 19, the air volume output can be concentrated, the blowing efficiency can be improved, and external foreign matter can be prevented from entering the main body part air duct. In addition, the shape and arrangement of the air outlet gaps in the air outlet cover 19 can be adjusted according to actual requirements, which is not limited here.

[0058] Further, in the existing technology, in order to avoid heat transfer generated by the high-voltage generator and the capacitor, the water ion assembly needs to be arranged in the assembly box, and the high-voltage generator and the capacitor are arranged radially outside the assembly box. It needs to occupy a large radial volume, at the same time, in order to avoid high temperature interference, the water ion assembly and the heating assembly are arranged at a certain distance, which further increases the radial required volume, resulting in a large overall size of the hair dryer.

[0059] Referring to Figure 2 and Figure 4 , in this embodiment, the ion assembly 13 is built in the central air duct 102, and the high-voltage generator 17 is arranged behind the ion assembly 13, which can effectively reduce the radial volume of the main body part 10, and further reduce the overall volume. At the same time, the high-voltage generator 17 is arranged inside the heater support 16, without occupying the extra internal space of the main body part 10, so that the overall structure is more compact. Further, in this embodiment, the ion assembly 13 is preferably a negative ion generator, which can stably provide negative ion blowing without setting a heat insulation structure.

[0060] Meanwhile, in the hair dryer using the ion assembly in the prior art, the air inlet provided by the handle air duct is divided into three streams when flowing to the main body part, and flows to the circuit board cavity, the ion assembly cavity in which the ion assembly is installed, and the annular air duct surrounding the ion assembly cavity respectively, the air is directly blown out to the main body part annular air duct while being divided to the circuit board cavity and the ion assembly cavity, which will result in the reduction of the air inlet utilization efficiency, the reduction of the effective air volume directly flowing to the air outlet, and the reduction of the air pressure.

[0061] Reference Figure 2 In the embodiment, the central air duct 102 and the annular air duct 103 are separated from the circuit board air duct 101 by the air guide support 12, most of the air flowing out can be directly guided to the annular air duct 103 of the main body part air duct by the air guide support 12 and blown out, which improves the effective air volume entering the annular air duct 103, further increases the air pressure, and improves the blowing efficiency. Meanwhile, the air flowing out of the handle air duct 22 does not need to be divided to the ion assembly 13, and part of the air flowing out of the handle air duct 22 only needs to be divided to the circuit board cooling air duct 101, after cooling the circuit elements, the air can flow to the central air duct 102 through the air inlet through hole 124 of the air guide support 12, and carry the ions generated by the ion assembly 13 in the central air duct 102 to flow out, which can carry away the heat around the ion assembly 13 and the heat of the high-voltage generator 13, and help the ions generated by the ion assembly 13 to be blown out quickly from the central air outlet 111. The air duct optimization design makes the overall structure more compact, improves the air inlet utilization efficiency, improves the effective air volume in the annular air duct 103, increases the air pressure, and ensures the functions of cooling the circuit elements and blowing out the ions through the central air duct 102.

[0062] In addition, in the embodiment, the structure through which the air flowing out of the handle air duct 22 flows in the main body part 10 is reduced, which effectively reduces the noise generated in the blowing process. In addition, the air volume flowing through the heating assembly 161 in the annular air duct 103 is increased, which can improve the red-hot condition of the heating wire in the heating assembly 161.

[0063] The above is only a preferred embodiment of the utility model, and is not used to limit the utility model, any modification, equivalent replacement and improvement made within the spirit and principle of the utility model should be included in the protection scope of the utility model.
