[0035] It should also be understood that the terminology used in this utility model specification is merely for describing specific aspects of the present application. It is important to understand that terms such as "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," indicating orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0036] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0037] like Figures 1 to 11 As shown, according to a first aspect of this application, this application provides an air guiding device for use in a hair dryer. The air guiding device includes an outer cover 20, an inner cover 30, a clamping assembly 10, and a pin assembly 40. The outer cover 20 is disposed outside the inner cover 30. The clamping assembly 10 is disposed between the outer cover 20 and the inner cover 30. The pin assembly 40 is movably installed on the side of the inner cover 30 away from the outer cover 20 and forms a linkage system with the clamping assembly 10, so that by pressing the outer cover 20, the pin assembly 40 can be retracted into the inner cover 30, thereby causing the clamping assembly 10 to open, so that the front end of the hair dryer can be inserted between the clamping assemblies 10. When the pressure applied to the outer cover 20 is released, the pin assembly 40 extends out of the inner cover 30, causing the clamping assembly 10 to close, so that it can be clamped to the front end of the blower in an emergency, thereby achieving a fixed connection between the air guide device and the blower, reducing disassembly and assembly, and allowing for one-handed operation to complete the assembly and disassembly. Compared with threaded connections or snap-fit ​​fixation, it can reduce the number of operation steps and meet the requirements of ergonomics.

[0038] By adopting the above technical solution, this application can transform the axial pressing action of the pin assembly 40 into the radial clamping action of the clamping assembly 10 through the linkage between the pin assembly 40 and the clamping assembly 10, thereby achieving quick one-handed assembly and disassembly. That is, the clamping assembly 10 can be opened or closed by pressing the outer cover 20. This mechanical transmission design can avoid the cumbersome traditional threaded connection, rotation operation, or the dependence on precise alignment of the buckle structure. When the user holds the hair dryer with one hand, the clamping release can be triggered by pressing the outer cover 20, which is intuitive and can also improve efficiency and reduce wrist strain for the operator.

[0039] In one alternative embodiment, the outer casing 20 has an air inlet end 21 and an air outlet end 22, and the inner casing 30 is disposed at the air outlet end 22. The radial cross-sectional area of ​​the inner casing gradually increases in the direction away from the air inlet end 21 to form the reverse effect of the Laval nozzle, which gradually reduces the airflow velocity and increases the static pressure, thereby reducing turbulence. The clamping assembly 10 is disposed in the air inlet end 21, and the pin assembly 40 is movably mounted on the inner casing 30 and protrudes to the side opposite to the outer casing 20. This drives the clamping assembly 10 to open or close, allowing the air guide device to be fixed to the front end of the blower via the clamping assembly 10. This solves the problem of inconvenient disassembly and assembly of traditional nozzles and improves airflow quality.

[0040] In one optional embodiment, the clamping assembly 10 includes a first clamping member 10a, a second clamping member 10b, a third clamping member 10c, and a fourth clamping member 10d arranged in a circular array. The first clamping member 10a, the second clamping member 10b, the third clamping member 10c, and the fourth clamping member 10d are rotatably mounted between the outer casing 20 and the inner casing 30. One of the pin assemblies 40 is driveably connected to the first clamping member 10a and the second clamping member 10b, and the other pin assembly 40 is driveably connected to the third clamping member 10c and the fourth clamping member 10d, thereby achieving a highly stable radial clamping force through a symmetrically distributed transmission structure. The four clamping members are arranged in a 90-degree circular array, forming a force balance system. Compared to clamping with two jaws, this application not only prevents the front end of the hair dryer from tilting and loosening due to unilateral force, but also evenly distributes the clamping force to the circumference of the front end of the hair dryer, avoiding localized deformation.

[0041] In an optional embodiment, the pin assembly 40 is provided with a slope structure 411. The first clamping member 10a and the second clamping member 10b have a first slope at their opposite ends, and the third clamping member 10c and the fourth clamping member 10d have a second slope at their opposite ends. The slope structure 411 is slidably connected to the first slope and the second slope, and is used to drive the first clamping member 10a, the second clamping member 10b, the third clamping member 10c and the fourth clamping member 10d to open or close. This is the core technology for realizing one-handed operation by efficiently converting the linear motion of the pin 41 into the rotational motion of the clamping members.

[0042] In one optional embodiment, the inner housing 30 is provided with a first rotating shaft 33, and the outer housing 20 is provided with a second rotating shaft 23. The first clamping member 10a, the second clamping member 10b, the third clamping member 10c, and the fourth clamping member 10d are provided with rotating holes 113. The second rotating shaft 23 passes through the rotating holes 113 and is connected to the first rotating shaft 33. The two sides of the pin assembly 40 are connected to the first rotating shaft 33 for transmission. Through the cooperation of the first rotating shaft 33 and the second rotating shaft 23, the first clamping member 10a, the second clamping member 10b, the third clamping member 10c, and the fourth clamping member 10d can rotate around the first rotating shaft 33 and the second rotating shaft 23.

[0043] In one optional embodiment, the inner cover 30 is provided with a first buckle 32 and a plurality of air outlets 31, and the outer cover 20 is provided with a first slot. The inner cover 30 is fixedly connected to the outer cover 20 by the first buckle 32 engaging with the first slot. The plurality of air outlets 31 are arranged around the inner cover 30, and the air inlet 21 communicates with the plurality of air outlets 31 for discharging the air entering from the air inlet 21.

[0044] In an alternative embodiment, the latch assembly 40 includes a button 42 and a latch 41 having a beveled structure 411. The inner cover 30 has button 42 holes formed on opposite sides. The button 42 is movably mounted in the button 42 holes. The latch 41 is inserted into the button 42 and can drive the first clamping member 10a, the second clamping member 10b, the third clamping member 10c and the fourth clamping member 10d to rotate through the beveled structure 411.

[0045] In one alternative implementation, guide grooves 421 are formed on both sides of the button 42. The guide grooves 421 cooperate with the first rotating shaft 33 to move the button 42 along the length direction of the first rotating shaft 33.

[0046] In one alternative embodiment, the first clamping member 10a, the second clamping member 10b, the third clamping member 10c, and the fourth clamping member 10d include a rotating plate 12, an adhesive strip 13, and a gripper 11. The gripper 11 is rotatably mounted between the outer cover 20 and the inner cover 30, the rotating plate 12 is rotatably mounted on the gripper 11, and the adhesive strip 13 is disposed on the rotating plate 12. Through the combination of a multi-stage rotating structure and an elastic contact surface, highly adaptable clamping is achieved.

[0047] In an optional embodiment, one end of the rotating plate 12 is provided with a rotating groove 114, and the other end of the rotating plate 12 is provided with a rotating hole 113. The rotating plate 12 is rotatably installed in the rotating groove 114, and the rotating hole 113 is rotatably connected to the second rotating shaft 23 of the outer cover 20.

[0048] In one alternative embodiment, mounting holes 1141 are formed on both sides of the rotating groove 114, and mounting shafts 121 are provided on both sides of the rotating plate 12, with the mounting shafts 121 rotatably mounted in the mounting holes 1141.

[0049] In an alternative embodiment, the gripper 11 is provided with a beveled portion 111 and a pivot portion 112. The pivot portion 112 is located on the side of the beveled portion 111 away from the rotating hole 113. The beveled portion 111 forms a first bevel and a second bevel that cooperate with the bevel structure 411 so that the pin assembly 40 can drive the gripper 11 to open or close.

[0050] In an alternative embodiment, the first clamping member 10a, the second clamping member 10b, the third clamping member 10c and the fourth clamping member 10d further include an elastic member 14, one end of which abuts against the gripper 11 and the other end of which abuts against the outer cover 20 and / or the inner cover 30, for driving the gripper 11 to close.

[0051] In an alternative embodiment, the gripper 11 is provided with ribs 115, which are arranged horizontally on both sides of the gripper 11 to enhance the strength of the gripper 11.

[0052] In one alternative embodiment, the inner cover 30 is provided with a guide rib 34 on the side facing the outer cover 20. The position of the guide rib 34 corresponds to the position of the air inlet 21 and is used to disperse the air blown into the air inlet 21 by the blower.
