[0036] In one embodiment of this utility model, such as Figures 1-3 and Figure 5 As shown, a nozzle device is provided, including a nozzle cylinder 10, a first magnetic absorbing member 20, a second magnetic absorbing member 30, and a connecting cylinder 40. The first magnetic absorbing member 20 and the second magnetic absorbing member 30 can be cylindrical. The nozzle cylinder 10 includes a flat section and a cylindrical section integrally formed, with a smooth transition between the flat section and the cylindrical section. The flat section and the cylindrical section are interconnected. A connecting post 11 is provided in the flat section, with both ends of the connecting post 11 connected to two opposite planes of the flat section. A mounting post 12 is also provided in the flat section, with one end of the mounting post 12 connected to the connecting post 40. The mounting post 11 is fixedly connected, and the other end of the mounting post 12 extends toward the cylindrical section. The axis of the mounting post 12 coincides with the central axis of the cylindrical section. A placement groove is opened at the other end of the mounting post 12 for placing the first magnetic component 20. The other end of the cylindrical section of the nozzle cylinder 10 is snapped together with the air outlet end of the connecting cylinder 40.

The first magnetic component 20 and the second magnetic component 30 are aligned and adsorbed together.

[0037] like Figure 1 and Figure 3 As shown, a limiting protrusion 42 is provided on the mounting platform 41. The cylindrical section of the nozzle cylinder 10 is fitted onto the limiting protrusion 42. The second magnetic suction component 30 is installed on the limiting protrusion 42. Multiple clearance holes 46 are provided on the limiting protrusion 42. The clearance holes 46 penetrate the mounting platform 41 and are connected to the connecting cylinder 40. A mounting groove 43 is provided on the limiting protrusion 42 and is located at the center of the surface of the limiting protrusion 42, aligned with the mounting column 12.

[0038] like Figure 1 and Figure 3As shown, an annular limiting plate 45 is provided on the side of the mounting platform 41. The annular limiting plate 45 is located at the connection between the mounting platform 41 and the end of the connecting cylinder 40. The open end of the cylindrical section of the nozzle cylinder 10 abuts against one side plane of the annular limiting plate 45. Positioning notches 451 are opened on the annular limiting plate 45 as needed. If there are multiple positioning notches 451, they are equally spaced, and the depth of the positioning notches 451 extends to a position flush with the outer side of the connecting cylinder 40.

[0039] like Figure 1 and Figure 3 As shown, a corresponding clearance groove 44 is provided on the side of the connecting cylinder 40 at the position corresponding to the positioning notch 451. One end of the clearance groove 44 passes through the end of the connecting cylinder 40, and the other end of the clearance groove 44 extends to the position adjacent to the corresponding positioning notch 451, guiding the sliding assembly of the connecting cylinder 40. The positioning protrusion provided on the air duct shell slides along the clearance groove 44 to the positioning notch 451 and engages. The groove width of the clearance groove 44 is the same as the opening width of the positioning notch 451 or the groove width of the clearance groove 44 is greater than the opening width of the positioning notch 451.

[0040] like Figure 1 and Figure 3 As shown, the side of the connecting cylinder 40 is provided with several snap-fit ​​holes 47. Each snap-fit ​​hole 47 is close to the air inlet end of the connecting cylinder 40 and is set through the side of the connecting cylinder 40.

The first annular groove 431 is provided along the bottom of the inner side of the mounting groove 43, and the second annular groove 432 is located at the center of the first annular groove 431. The centers of the first annular groove 431 and the second annular groove 432 coincide, and the second annular groove 432 is deeper than the first annular groove 431. The bottom of the second magnetic suction member 30 is aligned and engaged in the first annular groove 431 and the second annular groove 432.

[0042] like Figure 2As shown, the second magnetic suction component 30 includes a main body 31, a first annular protrusion 32, and a second annular protrusion 33. Both the first annular protrusion 32 and the second annular protrusion 33 are disposed on the bottom plane of the main body 31. The main body 31 is disc-shaped. The first annular protrusion 32 is disposed along the edge of the bottom plane of the main body 31. The radius of the second annular protrusion 33 is smaller than that of the first annular protrusion 32, so that the first annular protrusion 32 surrounds the second annular protrusion 33. The second annular protrusion 33 is higher than the first annular protrusion 32. The first annular protrusion 32 can be engaged in the first annular groove 431, and the second annular protrusion 33 can be engaged in the second annular groove 432. The side of the first annular protrusion 32 and the side of the main body 31 abut against the inner side of the mounting groove 43. The second annular protrusion 33 is engaged and positioned with the second annular groove 432. The first annular protrusion 32 and the first annular groove 431 assist in positioning to ensure the stability of the second magnetic suction component 30 during installation.

[0043] In another embodiment of this utility model, such as Figures 4-5 As shown, a hair dryer includes the aforementioned nozzle device, as well as a housing 50, a motor 60, and a control device 70. The housing 50 has a T-shaped structure, divided into a horizontal section for air outlet and a vertical grip section connected to the central area of ​​the horizontal section. A connecting cylinder 40 is installed at one end of the horizontal section of the housing 50. Several limiting members are provided on the inner side wall of the horizontal section, and each limiting member slides to a positioning notch 451 on the annular limiting plate 45 corresponding to a clearance groove 44 provided on the outer side wall of the connecting cylinder 40. Each limiting member is engaged with each positioning notch 451 to fix the installation angle of the connecting cylinder 40 and prevent rotation. A certain gap is left between the mounting platform 41 on the connecting cylinder 40 and the inner side of the opening of the horizontal section of the housing 50. One end of the cylindrical section of the nozzle cylinder 10 is engaged in the gap between the mounting platform 41 and the opening of the horizontal section of the housing 50. The air outlet end of the motor 60 is connected to the air inlet end of the connecting cylinder 40, and the motor 60 is connected to the connecting cylinder 40. The various snap-fit ​​holes 47 on the connecting cylinder 40 snap together to complete the fixed connection between the connecting cylinder 40 and the end of the motor 60. The outer wall of the motor 60 snaps together with the inner side of the outer shell 50. The air inlet end of the motor 60 extends to the other end of the horizontal section of the outer shell 50. An intercepting cover is set at the other end of the horizontal section of the outer shell 50 to prevent foreign objects from entering and affecting the normal operation of the motor 60. When the motor 60 is running, it drives the air on one side to be output to the air outlet through the other side of the motor 60, enters the connecting cylinder 40 and is output from the nozzle cylinder 10. The control device 70 is installed in the grip and is electrically connected to the motor 60. The wiring terminal of the control device 70 passes through the bottom of the grip and connects to the plug. When in use, the angle of the air outlet is adjusted by rotating the angle of the nozzle cylinder 10. External force pulls to separate the adsorption state between the first magnetic suction member 20 and the second magnetic suction member 30. Different nozzle cylinders 10 can be replaced.
