The shell 100 has at least one opening, which is located at one side of the shell 100. The wind collecting plate 200 is detachably mounted at the opening of the shell 100, for closing the shell 100 and guiding airflow into the shell 100. The air duct structure is fixedly arranged at the inner side of the wind collecting plate 200, and is located in the shell 100. One end of the air duct structure is connected with the wind collecting plate 200, and the other end is arranged close to the bottom wall of the shell 100. The air duct structure communicates with the internal space of the shell 100, and has a function of guiding airflow.

[0041] As shown in Figure 4 , in the embodiment, the specific structure form of the air duct structure is not limited. The air duct structure is integrally connected to the wind collecting plate 200, that is, the air duct structure is integrally connected with the wind collecting plate 200. For example, when the air duct structure is a plastic part, it can be made by integrally injection molding, so that it is integrally formed with the wind collecting plate 200. As an alternative embodiment, the air duct structure can also be connected to the wind collecting plate 200 in a detachable manner, which is convenient for assembly or maintenance. In this case, the air duct structure is fixed at the inner side of the wind collecting plate 200 by buckling, threading or other mechanical connecting pieces. The connection mode of the air duct structure can be selected according to specific requirements to meet the application requirements in different scenes.

[0042] Specifically, the air duct structure comprises a base plate 202 which encloses to form an air duct. The base plate 202 is divided into two sides along the thickness direction, one side of which is fixedly connected to the inner surface of the wind collecting plate 200; the other side of the base plate 202 extends and abuts to the bottom wall of the shell 100, and is in sealing cooperation with the surface of the bottom wall to form a complete air duct.

[0043] Further, referring to Figure 4 、 Figure 5 and Figure 6The bottom wall of the shell 100 is provided with a convex rib 104. The convex rib 104 is located inside the bottom wall of the shell 100 and protrudes outward from the surface of the bottom wall of the shell 100. In the preferred embodiment, the substrate 202 is attached to the convex rib 104. On the one hand, the convex rib 104 can provide support for the substrate 202, so that the substrate 202 can maintain good strength, especially when the area of the bottom wall of the shell 100 is large, so that the substrate 202 can maintain its shape and good air duct performance. On the other hand, the convex rib 104 can form a certain sealing effect on the volute and the air duct. It prevents the volute and the air duct from leaking, thereby maintaining good volute and air duct performance. As an alternative embodiment, there can be a gap between the substrate 202 and the convex rib 104. In this embodiment, the convex rib 104 has a side after protruding, and the attachment of the substrate 202 to the convex rib 104 means that the side of the substrate 202 is attached to the side of the convex rib 104. In this embodiment, the first connecting part 107 is arranged corresponding to the substrate 202. Specifically, the first connecting part 107 corresponds to the shape of the substrate 202, so that the substrate 202 can be installed through the first connecting part 107. The substrate 202 itself has a volute function, which better maintains the linearity of the volute and maintains good air duct performance.

[0044] Based on the above embodiment, as a further defined embodiment, as shown in Figure 5 and Figure 6 , the bottom wall of the shell 100 is provided with a reinforcing rib 105. The reinforcing rib 105 extends to the inner surface of the bottom wall of the shell 100 in the form of a protruding structure. As an alternative embodiment, the reinforcing rib 105 extends to the outer surface of the bottom wall of the shell 100 in the form of a protruding structure. As an alternative embodiment, the reinforcing rib 105 extends to the inner surface and the outer surface of the bottom wall of the shell 100 in the form of a protruding structure, respectively. After the protrusion of the reinforcing rib 105, it plays a role in enhancing the structural strength and stability of the bottom wall. In this embodiment, the hair dryer further comprises a wind source 400. The wind source 400 is located inside the shell 100 and is used to provide airflow. The wind source 400 comprises a motor 401, which is fixedly connected to the reinforcing rib 105. The reinforcing rib 105 provides a mounting support point for the motor 401, making the installation of the motor 401 more stable, reducing vibration transmission, and improving the overall operation performance and structural stability of the device. In addition, after the local strength is enhanced by the reinforcing rib 105, the overall thickness of the shell 100 can be appropriately reduced, thereby reducing the amount of raw materials used and reducing production costs.

[0045] Further, the reinforcing rib 105 is arranged in a ring shape. The ring-shaped reinforcing rib 105 can uniformly distribute external or internal stress and prevent local deformation of the equipment when subjected to stress. Due to the symmetry and continuity of the ring structure, the load-bearing capacity of the bottom plate 110 can be effectively improved, and local stress concentration can be avoided.
