The air outlet switching mechanism can realize three forms of air outlet: air outlet from the inner ring air duct, air outlet from the outer ring air duct, and air outlet from both the inner and outer ring air ducts simultaneously.

[0007] Furthermore, the air outlet switching mechanism includes an inner air ring adjustment plate that is rotatably mounted on the air outlet. The inner air ring adjustment plate is provided with an inner outlet. When the inner outlet coincides with the inner ring air duct, air can be discharged from both the inner and outer ring air ducts of the air outlet at the same time.

When the inner outlet coincides with the inner ring air duct and the outer outlet is misaligned with the outer ring air duct, air can be discharged from the inner ring air duct of the air outlet. When the inner outlet is misaligned with the inner ring air duct and the outer outlet coincides with the outer ring air duct, air can be discharged from the outer ring air duct of the air outlet. When the inner outlet coincides with the inner ring air duct and the outer outlet coincides with the outer ring air duct, air can be discharged from both the inner and outer ring air ducts of the air outlet simultaneously.

[0009] Furthermore, the inner air ring adjustment plate is provided with a toggle protrusion to facilitate gripping and rotation.

[0012] Furthermore, an outer limiting groove is provided on one side of the outer outlet, and an outer limiting rib is provided on one side of the outer ring air duct. When the outer limiting groove and the outer limiting rib are engaged and limited, the outer outlet and the outer ring air duct are in a misaligned state. When the outer limiting rib moves away from the outer limiting groove and abuts against the other side of the outer outlet, the outer outlet and the outer ring air duct are in an overlapping state.

[0013] Furthermore, the inner ring air duct is composed of a number of inner ventilation openings arranged in a ring; all the inner ventilation openings are evenly spaced; and / or, the outer ring air duct is composed of a number of outer ventilation openings arranged in a ring, all the outer ventilation openings are evenly spaced.

[0050] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0051] This invention provides an air outlet structure, including an air outlet 1, which has at least two air ducts, and an air outlet switching mechanism installed on the air outlet 1 to control the opening and closing of different air ducts. The air outlet switching mechanism can realize airflow through part or all of the air ducts to achieve multiple forms of air outlet control. Specifically, it can realize the switching of air outlet form from circular air outlet to annular air outlet to achieve the effect of changing the airflow.

[0052] To improve the real-time user experience and meet the needs of different customers, an air outlet switching mechanism is adopted to enable the hair dryer to correspond to different air outlet modes according to different air outlet structures, effectively improving the hair drying speed and shortening the usage time.

[0053] In this embodiment, there are two air ducts, namely the inner ring air duct 2 and the outer ring air duct 3. The air outlet switching mechanism can realize three forms of air outlet: air outlet from the inner ring air duct, air outlet from the outer ring air duct, and air outlet from both the inner and outer ring air ducts at the same time.

[0054] It should be noted that the inner ring air duct 2 and outer ring air duct 3 are defined by their distance from the center of the air outlet 1. The inner ring air duct 2 is closer to the center of the air outlet 1, while the outer ring air duct 3 is farther from the center of the air outlet 1 and closer to its outer edge. Furthermore, the shapes of the inner ring air duct 2 and outer ring air duct 3 can be customized as needed. However, both the inner ring air duct 2 and outer ring air duct 3 are arranged in a ring shape and include several ventilation openings. For example, the inner ring air duct 2 consists of several ring-shaped inner ventilation openings. All the inner ventilation openings are evenly spaced. Figure 1 , 2 Figures 3, 5, and 7-9 are schematic diagrams of a structural embodiment of the present invention. In these diagrams, the internal ventilation openings are annular fan-shaped, and there are three of them, spaced 120 degrees apart. Figures 29-31 The diagram shown is a structural schematic of another embodiment of the present invention. In this schematic diagram, the internal ventilation openings are in the shape of a ring segment structure, and there are three of them, spaced 120 degrees apart.

[0055] The outer ring duct 3 consists of several external ventilation openings arranged in a ring, with all external ventilation openings evenly spaced, such as... Figure 1 , 2 Figures 3, 5, and 10-12 are schematic diagrams of a structural embodiment of the present invention. In these diagrams, the external ventilation openings are in a ring structure, with six openings in total. Adjacent external ventilation openings are separated by blocks, thereby forming an outer ring air duct 3 with the largest possible area. Figure 14 , 29 As shown in -31, the external ventilation openings are in a ring structure, with three openings spaced 120 degrees apart.

[0056] like Figure 15 and 16 As shown, the air is supplied through the inner ring duct, meaning ventilation is only provided by the inner ring duct while the outer ring duct is closed. At this time, the airflow passes through the central area of ​​air outlet 1, resulting in low wind speed and gentle airflow. Figure 5 , 6 and Figure 19 , 20 As shown, air is supplied through the outer ring duct, meaning ventilation is only provided by the outer ring duct while the inner ring duct is closed. In this case, the airflow velocity is high, resulting in fast hair drying. Figure 3 , 4 and Figure 17 , 18 As shown, the inner and outer ring air ducts supply air simultaneously, which means that the inner and outer ring air ducts supply air at the same time, combining the advantages of the two air supply methods.

[0057] As an optional embodiment of the present invention, such as Figure 2 , Figure 7-9 As shown, the air outlet switching mechanism includes an inner air ring adjusting plate 4 rotatably mounted on the air outlet 1. The inner air ring adjusting plate 4 has an inner outlet 5. When the inner outlet 5 coincides with the inner ring air duct 2, air can be simultaneously discharged from both the inner and outer ring air ducts of the air outlet 1. When the inner outlet 5 is misaligned with the inner ring air duct 2, air can be discharged from the outer ring air duct of the air outlet. It should be noted that the specifications, shape, and quantity of the inner outlet 5 are adapted to the specifications, shape, and quantity of the inner ring air duct 2 to ensure that when the inner outlet 5 rotates to a designated position, it can fully open or completely block and close the inner ring air duct 2. Specifically, in this embodiment, the inner air ring adjusting plate 4 is provided with an elastic round buckle 16, and a corresponding mounting hole 17 is provided on the air outlet 1. The elastic round buckle 16 and the mounting hole 17 on the air outlet 1 are fitted together, allowing the inner air ring adjusting plate 4 to connect with the air outlet 1 and to rotate relative to it.

[0058] It should be noted that in this embodiment, the diameter of the inner air ring adjusting plate 4 is smaller than the diameter enclosed by the outer ring air duct 3, so that the inner air ring adjusting plate 4 will not block the outer ring air duct 3 of the air outlet 1, and the outer ring air duct 3 can always supply air. When the air outlet needs to be adjusted, it is only necessary to control the inner air ring adjusting plate 4 to rotate, so that the inner outlet 5 coincides with the inner ring air duct 2 and the inner ring air duct 2 is opened, thereby realizing the air supply of the inner ring air duct 2. This ultimately realizes the air supply mode of simultaneous air supply from the inner and outer ring air ducts. Alternatively, the inner outlet 5 can be adjusted to be completely offset from the inner ring air duct 2, and the inner ring air duct 2 can be closed, realizing the air supply mode switching of only the outer ring air duct supplying air.

[0059] Furthermore, to facilitate adjustment and air outlet switching, the inner air ring adjustment plate 4 is equipped with a toggle protrusion 8 for easy gripping and rotation.

[0060] Furthermore, to facilitate knowing the adjustment position and ensure that the adjustment is in place, an inner limiting groove 9 is provided on one side of the inner outlet 5, and an inner limiting rib 10 is provided on one side of the inner ring air duct 2. When the inner limiting groove 9 and the inner limiting rib 10 are engaged and limited, the inner outlet 5 and the inner ring air duct 2 are in an overlapping state. When the inner limiting rib 10 moves away from the inner limiting groove 9 and abuts against the other side of the inner outlet 5, the inner outlet 5 and the inner ring air duct 2 are in a misaligned state.

[0061] As another optional embodiment of the present invention, such as Figure 14 , 23As shown in Figure -28, the air outlet switching mechanism includes an inner air ring adjusting plate 4 and an outer air ring adjusting plate 6 that are rotatably mounted on the air outlet 1. The inner air ring adjusting plate 4 is provided with an inner outlet 5, and the outer air ring adjusting plate 6 is provided with an outer outlet 7. When the inner outlet 5 coincides with the inner ring air duct 2 and the outer outlet 7 is misaligned with the outer ring air duct 3, the air outlet can achieve air outlet through the inner ring air duct. When the inner outlet 5 is misaligned with the inner ring air duct 2 and the outer outlet 7 coincides with the outer ring air duct 3, the air outlet can achieve air outlet through the outer ring air duct. When the inner outlet 5 coincides with the inner ring air duct 2 and the outer outlet 7 coincides with the outer ring air duct 3, the air outlet can achieve air outlet through both the inner and outer ring air ducts simultaneously. Specifically, in this embodiment, the inner air ring adjusting plate 4 is provided with an elastic round buckle 16, and the air outlet 1 is provided with an assembly hole 17 at the corresponding position. The elastic round buckle 16 and the assembly hole 17 on the air outlet 1 are fitted together to connect the inner air ring adjusting plate 4 and the air outlet 1 and allow them to rotate relative to each other.

[0062] To facilitate adjustment and air outlet switching, both the inner air ring adjustment plate 4 and the outer air ring adjustment plate 6 are equipped with toggle protrusions 8 for easy gripping and rotation.

[0063] Since the outer diameter of the inner air ring regulating plate 4 is smaller than the diameter enclosed by the outer ring air duct 3, there is a gap between the actuating protrusions 8 on the inner and outer ring regulating plates, so they will not affect each other.

[0064] Furthermore, to facilitate knowing the adjustment position and ensure that the adjustment is in place, an inner limiting groove 9 is provided on one side of the inner outlet 5, and an inner limiting rib 10 is provided on one side of the inner ring air duct 2. When the inner limiting groove 9 and the inner limiting rib 10 are engaged and limited, the inner outlet 5 and the inner ring air duct 2 are in an overlapping state. When the inner limiting rib 10 moves away from the inner limiting groove 9 and abuts against the other side of the inner outlet 5, the inner outlet 5 and the inner ring air duct 2 are in a misaligned state.

[0065] Furthermore, an outer limiting groove 11 is provided on one side of the outer outlet 8, and an outer limiting rib 12 is provided on one side of the outer ring air duct 3. When the outer limiting groove 11 and the outer limiting rib 12 are engaged and limited, the outer outlet 7 and the outer ring air duct 3 are in a misaligned state. When the outer limiting rib 12 moves away from the outer limiting groove 11 and abuts against the other side of the outer outlet 7, the outer outlet 7 and the outer ring air duct 3 are in an overlapping state.

[0066] The air outlet structure provided by this invention allows for switching of air outlet modes by installing an air outlet switching mechanism on the air outlet, enabling users to switch air ducts at any time according to actual needs, thereby improving the drying speed and user comfort experience.

[0067] The present invention provides a hair dryer, including an air outlet structure.

[0068] Specifically, the hair dryer also includes a hair dryer housing 13, a heating element bracket 14, and a heating element 15.

[0069] The hair dryer provided by this invention can effectively and quickly switch between multiple airflow modes, with high convenience and fast drying speed, greatly shortening the hair dryer usage time. Users can select different airflow modes according to their real-time needs, improving the user experience.

[0070] How to use a hair dryer:

[0071] like Figure 1-12 The diagram shown is a structural schematic of one embodiment of a hair dryer. In this embodiment, as... Figure 5 and Figure 6 As shown, when the outer ring air duct needs to be used for air outlet, that is, when the inner air ring adjusting plate 4 is in the closed state, the actuating protrusion 8 on the inner air ring adjusting plate 4 is rotated clockwise or counterclockwise, so that the inner outlet 5 on the inner air ring adjusting plate 4 rotates relative to the air outlet 1 until the inner limiting groove 9 on it engages with the inner limiting rib 10 on the air outlet 1. At this time, the inner outlet 5 on the inner air ring adjusting plate 4 and the inner ring air duct 2 of the air outlet 1 are misaligned, thereby blocking the inner ring air duct 2. The airflow can only flow from the outer ring air duct 3 on the air outlet 1. At this time, the air outlet duct is annular and the wind speed is high.

[0072] like Figure 3 and Figure 4 As shown, when it is necessary to use the inner and outer ring air ducts to discharge air simultaneously, that is, when the inner air ring adjusting plate 4 needs to be in the open state, rotate the actuating protrusion 8 on the inner air ring adjusting plate 4 clockwise or counterclockwise. The inner outlet 5 on the inner air ring adjusting plate 4 rotates relative to the air outlet 1 until the inner limiting groove 9 on it is aligned with the inner limiting rib 10 on the air outlet 1. At this time, the inner outlet 5 on the inner air ring adjusting plate 4 is aligned with the inner ring air duct 2 of the air outlet 1, so that the inner ring air duct 2 is fully opened. The airflow can flow not only from the outer ring air duct 3 on the air outlet 1, but also from the inner ring air duct 2 of the air outlet 1. At this time, the air outlet channel area is annular + multiple fan-shaped, with a large air outlet area and large air volume.

[0073] like Figure 13-31 The diagram shown is a structural schematic of another embodiment of a hair dryer. In this embodiment, as... Figure 15 , 16As shown, when air needs to be discharged through the inner ring duct 2, that is, when the inner ring regulating plate 4 is in the open state and the outer ring regulating plate 6 is in the closed state, the actuating protrusion 8 on the inner ring regulating plate 4 is rotated clockwise or counterclockwise, and the inner outlet 5 on the inner ring regulating plate 4 rotates relative to the air outlet 1 until the inner limiting groove 9 on it and the inner limiting rib 10 on the air outlet 1 are locked and aligned to form an air outlet channel. The inner ring duct 2 is in the open state. The actuating protrusion 8 on the outer ring regulating plate 6 is rotated clockwise or counterclockwise, and the outer outlet 7 on the outer ring regulating plate 6 rotates relative to the air outlet 1 until the outer limiting groove 11 on it and the outer limiting rib 12 on the outer ring regulating plate 6 are locked and aligned. At this time, the outer outlet 7 on the outer ring regulating plate 6 and the outer ring duct 3 on the air outlet 1 are completely misaligned. The outer ring regulating plate 6 is in the closed state, the outer ring duct 3 is in the closed state, and the airflow flows out from the inner ring duct 2.

[0074] like Figures 19-20 As shown, when the outer ring air duct 3 needs to be used for air outlet, that is, when the outer air ring adjusting plate 6 is in the open state and the inner air ring adjusting plate 4 is in the closed state, the actuating protrusion 8 on the inner air ring adjusting plate 4 is rotated clockwise or counterclockwise, and the inner outlet 5 on the inner air ring adjusting plate 4 rotates relative to the air outlet 1 until the inner limiting groove 9 on it moves away from the inner limiting rib 10 on the air outlet 1, and the inner ring air duct 2 is in the closed state. The actuating protrusion 8 on the outer air ring adjusting plate 6 is rotated clockwise or counterclockwise, and the outer outlet 7 on the outer air ring adjusting plate 6 rotates relative to the air outlet 1 until the outer limiting groove 11 on it moves away from the outer limiting rib 12 on the outer air ring adjusting plate 6. At this time, the outer outlet 7 on the outer air ring adjusting plate 6 and the outer ring air duct 3 on the air outlet 1 are completely overlapped, the outer air ring adjusting plate 6 is in the open state, the outer ring air duct 3 is in the open state, and the airflow flows out from the outer ring air duct 3.

[0075] like Figure 17-18 As shown, when it is necessary to use the inner and outer ring air ducts to discharge air simultaneously, that is, when the outer air ring adjusting plate 6 is in the open state and the inner air ring adjusting plate 4 is in the open state, the actuating protrusion 8 on the inner air ring adjusting plate 4 is rotated clockwise or counterclockwise, and the inner outlet 5 on the inner air ring adjusting plate 4 rotates relative to the air outlet 1 until the inner limiting groove 9 on it is locked and aligned with the inner limiting rib 10 on the air outlet 1 to form an air outlet channel. The inner ring air duct 2 is in the open state. When the actuating protrusion 8 on the outer air ring adjusting plate 6 is rotated clockwise or counterclockwise, the outer outlet 7 on the outer air ring adjusting plate 6 rotates relative to the air outlet 1 until the outer limiting groove 11 on it is far away from the outer limiting rib 12 on the outer air ring adjusting plate 6. At this time, the outer outlet 7 on the outer air ring adjusting plate 6 is completely aligned with the outer ring air duct 3 on the air outlet 1. The outer air ring adjusting plate 6 is in the open state and the outer ring air duct 3 is in the open state. The airflow flows out from the inner ring air duct 2 and the outer ring air duct 3.

[0076] It should be noted that the hair dryer of the present invention, such as Figure 21 and 22 As shown, it can also control both the inner air ring adjusting plate 4 and the outer air ring adjusting plate 6 to the closed state. At this time, both the inner ring air duct 2 and the outer ring air duct 3 are in the closed state. The air outlet of the hair dryer can be adjusted to this state to achieve dust prevention.

[0077] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
