[0040] The following combination Figure 1-Figure 5 An electric hair dryer 100 of the present application is described.

[0041] See also Figure 1 As shown, the hair dryer 100 according to an embodiment of the present invention includes a main shell 110 , a heating component 140 and a nutrient bin 120 .

[0042] Specifically, the main housing 110 is provided with an air outlet 111 and an air inlet 112. A main air duct 113 and an auxiliary air duct 114 are provided inside the main housing 110. The main air duct 113 and the auxiliary air duct 114 are both connected to the air inlet 112 and the air outlet 111. The air flow of the auxiliary air duct 114 is smaller than the air flow of the main air duct 113. By providing the main air duct 113 and the auxiliary air duct 114, the air flow entering the main housing 110 is divided into two air flows with different flow rates, so that the wind flow rate and flow rate output from the air outlet 111 are more stable, the wind shape and air volume of the hair dryer 100 are improved, and the user experience is enhanced. Figure 3 As shown, in some embodiments, the air outlet 111 forms a first outlet 115 and a second outlet 116 , the first outlet 115 is connected to the main air duct 113 , and the second outlet 116 is connected to the auxiliary air duct 114 , wherein the first outlet 115 surrounds the second outlet 116 .

[0043] The heating component 140 is arranged in the main air duct 113, so that the heating component 140 can heat the airflow in the main air duct 113. At the same time, the airflow in the auxiliary air duct 114 will not be directly heated. The airflow in the auxiliary air duct 114 is less affected by the heating component 140, and the increase in the airflow temperature is smaller.

[0044] The nutrient bin 120 is suitable for storing nutrients, and nutrients can be hair care essential oil, hair cream, etc. The nutrient bin 120 is arranged in the auxiliary air duct 114 and is communicated with the auxiliary air duct 114. During the working process of the hair dryer 100, air flow enters the main housing 110 from the air inlet 112, wherein most of the air flow flows through from the main air duct 113 and flows out from the air outlet 111, and another part of the air flow flows through from the auxiliary air duct 114. When the air flow in the auxiliary air duct 114 flows through the nutrient bin 120, the nutrients in the nutrient bin 120 are taken out and blown onto the hair, so that the hair is cared for. By communicating the nutrient bin 120 with the auxiliary air duct 114, during the working process of the hair dryer 100, when the air flow flows to the air outlet 111, the nutrients are taken out and blown onto the hair, and there is no need to set the structure of the extra nutrients sent, thus simplifying the structure of the hair dryer 100, reducing its volume, and being convenient to use and take away.

[0045] At the same time, since the airflow in the auxiliary air duct 114 is less affected by the heating components and the air temperature is low, it will not damage the nutrients, thereby ensuring the maintenance effect of the nutrients. In addition, the nutrient bin 120 is placed in the auxiliary air duct 114 with a smaller air flow, making the airflow through the nutrient bin 120 more stable and with a lower flow rate, thereby stably providing nutrients and improving the user experience.

[0046] According to the electric hair dryer 100 of the embodiment of the present invention, by arranging the heating component 140 in the main air duct 113, the heating component 140 can heat the air flow of the main air duct 113, and at the same time, the air flow in the auxiliary air duct 114 will not be directly heated, and the air flow in the auxiliary air duct 114 is less affected by the heating component 140, and the temperature increase of the air flow is smaller. The nutrient bin 120 is arranged in the auxiliary air duct and is connected to the auxiliary air duct 114, so as to avoid the gas temperature in the auxiliary air duct 114 being too high and destroying the nutrients in the nutrient bin 120, thereby ensuring the use effect of the nutrients. In addition, during the operation of the electric hair dryer 100, when the air flow flows to the air outlet 111, the nutrients are taken out and blown onto the hair, and there is no need to set up an additional structure for sending nutrients, which simplifies the structure of the electric hair dryer 100, reduces its volume, and is convenient for use and storage.

[0047] In some embodiments, a heating element is provided on the peripheral wall of the heating assembly 140, and the heating element is located in the main air duct 113. The heating element can generate heat to heat the gas flowing through its surface. The auxiliary air duct 114 is provided in the heating assembly 140 and is separated from the heating element. In this way, when the airflow in the main air duct 113 and the auxiliary air duct 114 flows through the heating assembly 140, the airflow in the main air duct 113 can be heated by the heating assembly 140 to increase the temperature, while the airflow in the auxiliary air duct 114 will not be directly heated, and the airflow temperature in the auxiliary air duct 114 will be less affected.

[0048] See also Figure 2 As shown, according to some embodiments of the present invention, the nutrient bin 120 has an air inlet and an air outlet, and the cross-sectional area of the air outlet is larger than the cross-sectional area of the air inlet, so as to reduce the speed of the air flow output from the nutrient bin 120 and increase the output area of the air flow carrying nutrients. At least one of the air inlet and the air outlet is provided with an air guide slope to facilitate the diffusion of nutrients, and the air guide slope extends toward the outside of the nutrient bin from the air inlet to the air outlet. Figure 2 As shown, the air inlet end face and the air outlet end face of the nutrient bin 120 can both be circular, wherein the diameter of the air inlet end is smaller than the diameter of the air outlet end, and the air outlet end can be trumpet-shaped. A plurality of steps can be provided on the peripheral wall between the air inlet end face and the air outlet end face to cooperate with the inner wall of the main shell 110 to support the nutrient bin 120. Figure 4 As shown, in some embodiments, a plurality of air outlet holes 121 are provided on the end face of the air outlet end, and the plurality of air outlet holes 121 are evenly distributed in the middle of the nutrient bin 120. Specifically, the plurality of air outlet holes 121 are evenly distributed around the central axis of the nutrient bin 120 to make the airflow at the air outlet end of the nutrient bin 120 more uniform.

[0049] According to some embodiments of the present invention, the hair dryer 100 further includes a flow guide 144, which is disposed in the main housing 110 and located at the air inlet 112. The flow guide 144 is used to divert the air flow at the air inlet 112, so that part of the gas flows to the main air duct 113 and the other part of the gas flows to the auxiliary air duct 114. Figure 2 The guide member 144 is provided with a bent structure that extends into the air inlet 112 to divide the air inlet 112 into two areas, one of which is connected to the main air duct 113 and the other is connected to the auxiliary air duct 114. The area of the area connected to the main air duct 113 is larger than the area of the area connected to the auxiliary air duct 114. The heating component 140 is disposed within the main housing 110 and is closer to the air outlet 111 than to the air inlet 112. The heating component 140 is used to heat the airflow. The main housing 110, the heating component 140, and the guide member 144 collectively define the main air duct 113 and the auxiliary air duct 114.

[0050] See also Figure 1 and Figure 2 As shown, according to some embodiments of the present invention, a heat insulating tube 130 is provided in the main shell 110, the heat insulating tube 130 is located at the air outlet 111, the heat insulating tube 130 is embedded in the main shell 110, and the heat insulating tube 130 is in contact with the inner wall of the main shell 110, as shown in FIG. Figure 5As shown, at least one limiting rib 132 is provided on the outer peripheral wall of the insulation tube 130, and a groove is provided on the inner wall of the main shell 110. The limiting rib 132 is suitable for being embedded in the groove to limit the insulation tube 130. There can be two limiting ribs 132, and the two limiting ribs 132 are distributed along the circumference of the insulation tube 130 at intervals and symmetrically distributed. The limiting rib 132 can extend along the circumferential direction of the insulation tube 130 to increase the contact area. The insulation tube 130 can separate the heating component 140 from the main shell 110, reduce the heat transfer between the heating component 140 and the main shell 110, and avoid the main shell 110 from being too hot and causing inconvenience in use. The nutrient bin 120 is arranged in the insulation tube 130 and connected to the insulation tube 130. The nutrient bin 120 can be connected to the insulation tube 130 by screws or magnetic parts.

One side edge of the positioning rib 131 is connected to the inner wall of the heat-insulating tube 130, and the other side edge defines a fixed space, and the nutrient bin 120 is fixed in the fixed space. Figure 2 As shown, a fixing platform 133 may be provided within the insulating cylinder 130, and the nutrient bin 120 may be detachably connected to the fixing platform 133. A magnetic member may be provided on the fixing platform 133, with the air inlet end of the nutrient bin 120 facing the magnetic member. The magnetic member generates suction to secure the nutrient bin 120. Furthermore, a stepped portion is provided on the peripheral wall of the nutrient bin 120, and a positioning portion is provided on the positioning wall to cooperate with the stepped portion. The stepped portion and the positioning portion cooperate to support the nutrient bin 120, so that the air inlet end of the nutrient bin 120 is spaced a certain distance from the fixing platform 133, allowing airflow to enter the nutrient bin 120 through the air inlet end. In some embodiments, an excitation coil is provided within the nutrient bin 120, which is used to stimulate the volatilization of nutrients. The power supply end of the excitation coil is located at the air inlet end of the nutrient bin 120. A connecting socket is provided within the insulating cylinder 130, and the air inlet end is connected to the connecting socket to power the excitation coil. The connecting socket can be provided on the fixing platform 133, and the air inlet end of the nutrient bin 120 can be plugged into the connecting socket.

[0052] like Figure 2 As shown, the peripheral wall of the nutrient bin 120 is spaced apart from the inner peripheral wall of the heat-insulating cylinder 130. The nutrient bin 120 can be supported by providing a plurality of spaced apart positioning ribs 131 so that the nutrient bin 120 is spaced apart from the inner wall of the heat-insulating cylinder 130. Figure 3 As shown, there are three air flows out of the air outlet 111, wherein the outermost air flow is the gas output from the main air duct 113 (as shown in FIG. Figure 3 The middle circle is the gas output from the auxiliary air duct 114 (as shown by the arrow 2). Figure 3The innermost circle is the gas with nutrients output from the nutrient bin 120 (as shown by the arrow 3). Figure 3 The flow rate and speed of each layer of air flow can be different.

[0053] See also Figure 1 and Figure 2 As shown, according to some embodiments of the present invention, the heating component 140 includes a fixed bracket 141 and a heating module 142, and the heating module 142 is sleeved on the fixed bracket 141 and connected to the fixed bracket 141. In some embodiments, the heating module 142 and the fixed bracket 141 are both cylindrical, and one of the outer circumferential surface of the fixed bracket 141 and the inner circumferential surface of the heating module 142 is provided with ribs, and the other is provided with a groove body, and the ribs and the groove body both extend along the axial direction of the fixed bracket 141, and the ribs are embedded in the groove body to connect the heating module 142 and the fixed bracket 141 and perform circumferential limiting. The insulation tube 130 is connected to the guide member 144, and the guide member 144 and the insulation tube 130 jointly define an installation space, and the heating component 140 is arranged in the installation space. Among them, the length of the installation space is equal to or slightly smaller than the length of the heating component 140, the heating module 142 is against the guide member 144, and the fixing bracket 141 is against the insulation tube 130, that is, the heating component 140 is clamped by the guide member 144 and the insulation tube 130 to fix the heating component.

[0054] like Figure 2 and Figure 3 As shown, the main shell 110, the guide member 144 and the fixed bracket 141 together define the auxiliary air duct 114. At the fixed bracket 141, the auxiliary air duct 114 is located inside the fixed bracket 141. The peripheral wall of the fixed bracket 141 separates the gas in the auxiliary air duct 114 from the heating module 142, preventing the air flow temperature in the auxiliary air duct 114 from being too high and causing damage to the nutrients in the nutrient bin 120. The main shell 110, the guide member 144 and the peripheral wall of the heating module 142 together define the main air duct 113. The heating module 142 heats the gas in the main air duct 113. Figure 2 As shown, according to some embodiments of the present invention, the hair dryer 100 further includes a fixing ring 145 . The fixing ring 145 is sleeved on the main housing 110 and abuts against the heat insulating tube 130 to limit the heat insulating tube 130 .

[0055] like Figure 1 and Figure 2As shown, in some embodiments, the hair dryer 100 further includes a handle assembly and a control panel 143, wherein the control panel 143 is connected to the heating element 140 to control the heating element 140.

Figure 3 As shown by the arrow 1, when the airflow passes through the guide member 144 at the air inlet 112, it is divided into two airflows, one of which flows toward the side of the guide member 144 away from the air outlet 111 and flows upward (as shown in FIG. Figure 3 ) into the fixing bracket 141 (as shown in the direction Figure 3As shown by the arrow 3 in the middle, the airflow flows to the right in the fixed bracket 141. At the air inlet end of the nutrition bin 120, the airflow in the auxiliary air duct 114 is divided into two airflows, one of which flows directly to the air outlet 111 and then flows out (as shown in the figure).
