[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example: Figure 1-5 As shown, the air source structure applied to the hair dryer includes a frame 1, on which an air duct assembly 2 and a hot air assembly 3 are provided. The air duct assembly 2 has an air channel 201, an air outlet 202 and an air inlet 203. The air outlet 202 and the air inlet 203 are opposite each other and are respectively connected to the air channel 201. The air outlet 202 is in front and the air inlet 203 is in the back. The hot air assembly 3 is housed in the air channel 201 and is detachably fixedly connected to the air duct assembly 2. The hot air assembly 3 is used to drive the gas to flow along the air channel 201 from the air inlet 203 to the air outlet 202. An external air source component 5 for connecting an external air duct is provided on one side of the air inlet 203.

[0023] The air source structure used in hair dryers has the following two usage modes:

[0024] In mode 1, the hot air assembly 3 is installed in the air duct 201. The hot air assembly 3 drives the gas to flow along the air duct 201 from the air inlet 203 to the air outlet 202 to achieve hair blowing.

[0025] In mode two, the hot air assembly 3 is detached from the air duct 201, and the household or commercial air duct is connected to the air duct assembly 2 via the external air source component 5. The household or commercial air duct drives the gas to flow along the air duct 201 from the air inlet 203 to the air outlet 202 to achieve hair drying.

[0026] In summary, this embodiment provides an air source structure for a hair dryer to solve the problems of existing hair dryers where the air source structure is fixed on the frame, users cannot change the air source structure according to their needs, maintenance is inconvenient, and adaptability is poor. This is mainly achieved by configuring a hot air component 3 that is detachably and fixedly connected to the air duct assembly 2 in the air duct 201, and configuring an external air source component 5 for connecting an external air duct on one side of the air inlet 203. This allows the air source structure for the hair dryer to have multiple usage modes, allowing users to change the air source according to their needs, making it convenient to use, highly adaptable, and easy to maintain.

[0027] In this embodiment of the invention, the outer wall of the hot air assembly 3 is tightly fitted to the inner wall of the air duct 201, allowing the hot air assembly 3 to move along the air duct 201. A stop 208 is provided on the inner wall of the air duct 201, which abuts against the hot air assembly 3 to restrict its forward movement. The hot air assembly 3 is inserted into the air duct 201 through the air inlet 203 and can move along the air duct 201. This arrangement, by providing a stop 208 on the inner wall of the air duct 201 to restrict the forward movement of the hot air assembly 3, prevents the hot air assembly 3 from being over-inserted into the air duct 201 and becoming difficult to remove.

[0028] In this embodiment of the invention, the hot air assembly 3 includes an inner cylinder (not shown in the figure), a motor (not shown in the figure), fan blades (not shown in the figure), and a heating wire (not shown in the figure). The inner cylinder is disposed within the air duct 201 and is tightly fitted to the air duct 201. The inner cylinder can move along the air duct 201. The motor, fan blades, and heating wire are disposed within the inner cylinder. The fan blades are driven by the motor, and the heating wire is disposed on the side of the fan blades facing away from the air inlet 203. By configuring the hot air assembly 3 with an inner cylinder, a motor, fan blades, and a heating wire, the fan blades are driven by the motor, and the heating wire is disposed on the side of the fan blades facing away from the air inlet 203, the hot air assembly 3 can drive gas to flow along the air duct 201 from the air inlet 203 to the air outlet 202, delivering hot or cold air.

[0029] In this embodiment of the utility model, the duct assembly 2 is provided with a protective cover 4 that covers the air inlet 203. The protective cover 4 is detachably fixedly connected to the duct assembly 2 and has an air intake hole 401 communicating with the air duct 201. The above-mentioned arrangement, by configuring the protective cover 4 that covers the air inlet 203 on the duct assembly 2, avoids the danger of accidental contact with the motor by the user when using the device in mode 1.

[0030] In this embodiment of the invention, the air duct 201 has a front-to-back extending air inlet branch 204, and an air inlet 203 is formed at the rear end of the air inlet branch 204. The hot air assembly 3 is housed within the air inlet branch 204. The above arrangement, by placing the hot air assembly 3 within the front-to-back extending air inlet branch 204, makes the hot air assembly 3 easy to assemble and disassemble.

[0031] In this embodiment of the invention, the external air source component 5 is a magnetic component extending circumferentially along the air inlet 203. When using mode two, the user simply attaches the air duct to the external air source component 5, making the connection simple and quick.

[0032] In this embodiment of the utility model, the external air source component 5 is provided on the outer wall of the air duct assembly 2, and the air duct is magnetically attached to the external air source component 5 and sleeved on the outside of the air duct assembly 2.

[0033] In another embodiment, the external air source component 5 is located on the inner wall of the air duct 201, and when the air duct is magnetically attached to the external air source component 5, it is partially embedded in the air duct assembly 2.

[0034] In another embodiment, the external air source component 5 is attached to the rear end of the air duct assembly 2, and the air duct is magnetically attached to the external air source component 5 and abuts against the rear end of the air duct assembly 2.

[0035] In this embodiment of the invention, the duct assembly 2 includes an inlet duct 205 and an outlet duct 206. The inlet duct 205 is mounted on the frame 1 and extends back and forth. The outlet duct 206 is located at the front end of the inlet duct 205 and is strip-shaped. The inlet duct 205 and the outlet duct 206 are connected to form an air duct 201. An air inlet 203 is located at the rear end of the inlet duct 205, and an air outlet 202 is located on the side of the outlet duct 206 facing away from the frame 1. There are several outlets 202, which are spaced apart along the length of the outlet duct 206. The outlet duct 206 has an outlet branch duct 207 extending along its length. By configuring the duct assembly 2 with an inlet duct 205 extending back and forth and an outlet duct 206 located at the front end of the inlet duct 205 and being strip-shaped, the air duct 201 has a simple structure, and the hot air assembly 3 or the external air duct has a good blowing effect.
