[0003] Hair dryers are commonly used household appliances, mainly used for drying and shaping hair, and can also be used for local drying, heating and treatment in laboratories, physiotherapy rooms, industrial production, art, etc., and are widely used. In particular, hot hair dryers are used for a variety of purposes, such as drying materials (such as paint and hair), and cleaning or stripping surface layers.

[0004] The outlet accessories are auxiliary parts connected to the outlet of the hair dryer. They come in various shapes and can change the air duct to provide a more diverse hair-drying experience. For example, the heat drying hood (commonly known as a diffuser) is used to dry curly hair when using a hair dryer to dry hair, so that the curly hair is not easily messy and can maintain the original curly hair shape after drying the hair. The diffuser guides the air flow, making the hair dryer have a better air outlet effect.

The air outlet direction through the air outlet is in an angle relationship with the longitudinal length direction of the air passage cavity, and under the cooperation of the plurality of air outlets, the airflow discharged through the air outlet surrounds the outer periphery of the plurality of arc-shaped shells, so that the hair near the arc-shaped shells can be adsorbed and wrapped around the outer surface of the arc-shaped shells. Example 2 has certain defects, for example: a single accessory has only a one-way air outlet structure (one of the forward or reverse directions), which cannot meet the hair styling needs of different users.

[0048] Embodiment 1

[0049] Reference Figure 1 to Figure 14 , an air duct structure of a hair dryer air outlet accessory, comprising:

[0050] The air outlet bracket 1 is cylindrical, and has a main flow channel 101, a plurality of clockwise air outlets 102, and a plurality of counterclockwise air outlets 103, and the clockwise air outlets 102 and the counterclockwise air outlets 103 are arranged at intervals from each other;

[0051] A switching shaft 2, which is arranged in the main flow channel 101 and is coaxially arranged with the air outlet bracket 1, and the switching shaft 2 acts on the air outlet bracket 1 to make the main flow channel 101 connected to one of the clockwise air outlet 102 and the counterclockwise air outlet 103, and disconnected from the other;

[0052] The main flow channel 101 is arranged parallel to the axial direction of the air outlet bracket 1, the clockwise air outlet 102 and the counterclockwise air outlet 103 are arranged perpendicular to the axial direction, and the clockwise air outlet 102 and the counterclockwise air outlet 103 have an arc-shaped turning section 104;

[0053] A plurality of partition ribs 105 are disposed in each of the clockwise air outlet 102 and the counterclockwise air outlet 103 to separate each of the clockwise air outlet 102 and the counterclockwise air outlet 103 into a plurality of independent air outlet units 1051 .

[0054] The above content is the basic structural scheme of the utility model. The air outlet attachment can be used in conjunction with the hair dryer 5, and is generally detachably assembled at the air outlet port of the hair dryer 5. When in use, the airflow blown out by the hair dryer 5 first enters the main flow channel 101 of the air outlet bracket 1, and then turns from the main flow channel 101 to each air outlet (clockwise to the air outlet 102 or counterclockwise to the air outlet 103) and is discharged outward.

[0055] Among them, in the process of the main flow channel 101 turning to each air outlet, a 90-degree turn of the airflow is achieved. In this case, the airflow is unstable and the flow direction is relatively chaotic. Therefore, by setting the subsequent arc-shaped turning section 104, it can guide the airflow, and the arc-shaped structure reduces the structural resistance and prevents the generation of reverse airflow, thereby accelerating the forward flow of the airflow and stabilizing the flow direction of the airflow. On the other hand, by setting a plurality of partition ribs 105, a plurality of independent air outlet units 1051 are formed, and preferably the spacing between adjacent partition ribs 105 is the same, so that the size of each air outlet unit 1051 is the same, so that the air output is more uniform.

[0056] It should be particularly emphasized that, unlike the prior art, the utility model has both a clockwise air outlet 102 and a counterclockwise air outlet 103. When the rotating shaft 2 is switched, the main flow channel 101 can be connected to only one of the clockwise air outlet 102 and the counterclockwise air outlet 103 at a single time, thereby forming a complete annular clockwise vortex airflow 1021 or a counterclockwise vortex airflow 1031 on the outer peripheral wall of the air outlet bracket 1. The bidirectional vortex airflow can meet the needs of different users for air outlet direction.

[0057] It is worth pointing out that the specific composition structure of the air outlet bracket 1 is as follows: the air outlet bracket 1 includes a bracket body 11 and a plurality of air outlet panels 12. A plurality of mounting grooves 111 are evenly provided on the outer wall of the bracket body 11. One air outlet panel 12 is correspondingly inserted into each mounting groove 111, and the clockwise air outlet 102 and the counterclockwise air outlet 103 are formed between the bracket body 11 and the air outlet panel 12. Preferably, there are 6 air outlet panels 12, and there are 6 mounting grooves 111 which are arranged on the bracket body 11 at intervals of 60 degrees. The air outlet panels 12 correspond to the mounting grooves 111 one by one, and are just adapted to the 360-degree cylindrical air outlet bracket 1, presenting a centrally symmetrical structure as a whole.

[0058] A more preferred positioning structure for the air outlet panel 12 is that the inner end of the air outlet panel 12 has a positioning strip 121, and the inner end of the mounting groove 111 is provided with a positioning slot 112, and the positioning strip 121 is inserted into the positioning slot 112 to form an interference fit, thereby making the plug-in fit between the air outlet panel 12 and the bracket body 11 more stable and preventing shaking, thereby making the shapes of the clockwise air outlet 102 and the counterclockwise air outlet 103 more stable, so that the wind direction of the air outlet is more stable.

[0059] It is worth mentioning that the center point of the air outlet panel 12, the positioning bar 121, the limit block 113 and the center point of the bracket body 11 are all arranged on the same straight line, so that the center of gravity of each component is on the same straight line, forming a symmetrical structure on the counterweight, so that the overall structure is more stable and reliable.

[0060] Embodiment 2

[0061] Based on the structure of the first embodiment, this embodiment provides an important upgrade, mainly about the air outlet bracket 1, specifically: Fig.11 The outer wall of the air outlet bracket 1 has a convex area 13 and a concave area 14, the concave area 14 is connected to the convex area 13 through an arc section 15, and the clockwise air outlet 102 and the counterclockwise air outlet 103 are arranged at the concave area 14. By setting the convex position 13 and the concave position 14 and limiting the position of the air outlet, the effect that can be achieved is that the airflow at the clockwise air outlet 102 or the counterclockwise air outlet 103 is discharged from a position close to the inside, and finally leaves the outer peripheral wall of the air outlet bracket 1 through the convex position 13 after flowing along the arc section 15. Firstly, the airflow can flow along an arc path to form a vortex airflow; secondly, in terms of physical structure, especially between the adjacent clockwise air outlet 102 and counterclockwise air outlet 103, a low-high-low surface structure is formed, and the convex position 13 plays a high-point diversion role, so that the airflow discharged from the clockwise air outlet 102 will not enter the counterclockwise air outlet 103, and the airflow discharged from the counterclockwise air outlet 103 will not enter the clockwise air outlet 102.

[0062] Embodiment 3

[0063] In this embodiment, the preferred configuration for the switching shaft 2 is as follows: Figure 2 , Figures 9 to 13 The switching shaft 2 has a blocking strip 21, and the blocking strip 21 can be aligned with any one of the clockwise air outlet 102 and the counterclockwise air outlet 103 to disconnect the clockwise air outlet 102 or the counterclockwise air outlet 103 from the main flow channel 101.

[0064] It should be noted that if the rotation of the switching shaft 2 is not effectively constrained, the switching shaft 2 may rotate excessively or insufficiently, resulting in inadequate blocking of the air outlet, and further causing air leakage, turbulence, etc. Therefore, in order to limit the movement trajectory of the blocking bar 21, the adopted structure is set as follows: a plurality of limit blocks 113 are evenly arranged on the inner peripheral wall of the bracket body 11, and a rotation gap 114 is formed between adjacent limit blocks 113, and a blocking bar 21 is correspondingly arranged in each rotation gap 114, and the blocking bar 21 can reciprocate in the rotation gap 114.

[0065] Furthermore, the switching shaft 2 is provided with a plurality of connecting rings 22, each connecting ring 22 connects the blocking strips 21 together; a ventilation gap 23 is formed between the connecting ring 22 and the blocking strips 21, and the ventilation gap 23 and the blocking strips 21 are arranged at intervals from each other. The connecting ring 22 can firstly play a structural connection role, connecting the blocking strips 21 in series and forming the ventilation gap 23; secondly, it can play a structural support role, improving the overall strength of the switching shaft 2.

[0066] Preferably, the switch shaft 2 is used in a structure where an operating knob 3 is connected to the switch shaft 2, and the operating knob 3 extends out of the air outlet bracket 1. The user can drive the switch shaft 2 to rotate relative to the air outlet bracket 1 (main flow channel 101) by turning the operating knob 3, thereby realizing the switching function of the air outlet (clockwise air outlet 102 and counterclockwise air outlet 103).

[0067] Embodiment 4

[0068] Based on the structure of any of the above embodiments, this embodiment provides a preferred docking structure between the air outlet attachment and the hair dryer 5, specifically: Figure 5 , Figure 6 , Fig.14 The air outlet bracket 1 is connected and conducted with the hair dryer 5 through the drainage bracket 4. The specific connection method can be magnetic connection, thread connection, screw connection, etc., which is not particularly limited here.

[0069] It is worth mentioning that an inverted cone-shaped air-gathering channel 41 is provided on the drainage bracket 4, and the main flow channel 101 is connected to the inverted cone-shaped air-gathering channel 41 to achieve the functions of airflow convergence, pressurization and acceleration.

[0070] It is worth noting that other technical solutions of the present invention belong to the prior art and will not be described in detail.

[0071] The above is only a preferred embodiment of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the concept of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
