[0048] When in use, the required air outlet accessories 60 (such as air nozzles) can be installed on the accessory connection structure 122, so that the channel of the air outlet accessories 60 is connected with the air outlet 121, that is, the airflow blown out from the air outlet 121 can enter the channel of the air outlet accessories 60, and then blown out from the airflow outlet of the air outlet accessories 60, so that different air outlet forms can be achieved through different air outlet accessories 60. It can also be used without installing the air outlet accessories 60, that is, the airflow directly blown out from the air outlet 121 can be used to dry water stains on the desktop, clothes or hair, etc.

[0049] The silicon carbide heating element 30 is a heating structure as a whole, that is, there are at least two spaced connection parts 37 on the silicon carbide heating element 30, and the power supply circuit is connected through at least two connection parts 37. After the power is turned on, the current flows through the silicon carbide heating element 30, thereby converting the electrical energy into thermal energy. When the airflow flows through the surface of the silicon carbide heating element 30, the airflow can be heat-exchanged with the silicon carbide heating element 30, thereby heating the airflow flowing through the silicon carbide heating element 30. The surface of the silicon carbide heating element 30 refers to the surface of the silicon carbide heating element 30 that is exposed to the air and can contact the airflow, including the gap wall surface formed by the silicon carbide heating element 30 and the inner wall surface of the through hole.

After the blank is dried, it is placed in a sintering furnace for sintering to obtain the silicon carbide heating element 30.

[0051] The technical solution of the utility model adopts a silicon carbide heating element 30, so that the surface of the silicon carbide heating element 30 is used as a heat exchange surface to directly exchange heat with the airflow flowing through the air duct 101. The silicon carbide heating element 30 has a high thermal efficiency and can quickly generate heat, so that the outlet airflow can be quickly heated. Compared with the transmission electric heating wire heating device, the silicon carbide heating element 30 is an integrated structure with a simple structure and a small size. While ensuring the heating effect, the space occupied in the handle 10 can be reduced. Therefore, the silicon carbide heating element 30 can be better arranged in the curved air outlet section 12, and the curved air duct 101 in the air outlet section 12 can be fully utilized, thereby improving the space utilization rate in the new air duct, which is conducive to reducing the size of the handle 10 and facilitating the user to hold and use it.

[0052] In some embodiments, the new hair dryer further includes an air outlet accessory 60, which is detachably connected to the accessory connection structure 122. In this way, the user can rotate and install the air outlet accessory 60 as needed, thereby increasing the application scenarios of the new hair dryer.

[0053] The air outlet accessory 60 may have various forms. For example, in some embodiments, Figure 3 and Figure 4 , the air outlet accessory 60 is an air nozzle, such as a diffuser air nozzle, a wind collection nozzle or an anti-flying air nozzle, etc. In other embodiments, refer to Figure 5 The air outlet accessory 60 is a comb head, and a plurality of comb teeth and a plurality of air outlets are arranged around the comb head, and the air outlets are located between the comb teeth. The comb teeth and the air outlets may be arranged only on one side or two opposite sides of the comb head, or on the outer circumference of the comb head.

[0054] In some embodiments, the new hair dryer further includes a heat insulating component 50, which is disposed inside the handle 10 and surrounds the circumference of the silicon carbide heating element 30. This can reduce the heat conduction of the silicon carbide heating element 30 to the outer surface of the handle 10, which is beneficial to reduce heat loss and prevent the handle 10 from overheating and scalding the user or causing discomfort during use. The heat insulating component 50 is cylindrical in shape and has a channel with two ends passing through it. The silicon carbide heating element 30 is disposed in the channel, and its material can be ABS plastic, PP plastic, or heat insulating foam, etc.

[0055] In some embodiments, a convex rib 38 is provided on the outer circumference of the silicon carbide heating element 30, and a slot is provided in the heat insulating component 50, the slot extends along the axial direction of the heat insulating component 50, and the convex rib 38 is correspondingly inserted into the slot. Specifically, the slot extends to one end of the heat insulating component 50 or the end of the slot close to one end of the heat insulating component 50 is open, so that the silicon carbide heating element 30 can be installed into the heat insulating component 50 from one end of the heat insulating component 50 in a state where the convex rib 38 corresponds to the slot.

[0056] In some embodiments, an air inlet 111 is provided at one end of the grip section 11 away from the air outlet section 12, and the fan assembly 20 is located between the silicon carbide heating element 30 and the air inlet 111. This can prevent the hot air flow from passing through the fan assembly 20, and can also better dissipate heat for the fan assembly 20.

[0057] Optionally, at least one of the end surface and the peripheral side of the gripping section 11 is provided with an air inlet 111. That is, the air inlet 111 can be provided on the peripheral side of the gripping section 11, or on the end surface of the gripping section 11, or on both the peripheral side and the end surface of the gripping section 11.

[0058] In some embodiments, the novel air duct further includes a circuit assembly 40, and the fan assembly 20 and the silicon carbide heating element 30 are both electrically connected to the circuit assembly 40; the circuit assembly 40 is located between the silicon carbide heating element 30 and the fan assembly 20, or the circuit assembly 40 is located on the side of the fan assembly 20 away from the silicon carbide heating element 30. Such an arrangement can prevent hot air from passing through the fan assembly 20 and the circuit assembly 40, and can also better dissipate heat from the fan assembly 20 and the circuit assembly 40.

[0059] In some embodiments, a protective net 123 is provided at the air outlet 121. This can prevent foreign objects from entering the air duct 101 even when the air outlet accessory 60 is not installed, and can also prevent users from accidentally inserting their fingers into the air duct 101 and getting burned.
