[0018] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of this application. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0019] Please see Figure 1 and Figure 4 The air vent device 100 includes an outer frame 1, a flow guide 2, and a fixing assembly 3. The outer frame 1 has a ventilation cavity 10 for airflow. The fixing assembly 3 is disposed on the outer frame 1 and is used to connect the flow guide 2 to the outer frame 1. The flow guide 2 is disposed in the ventilation cavity 10 and extends along the ventilation cavity 10. The flow guide 2 is used to guide and divert the airflow.

[0020] For the outer frame 1 mentioned above, please refer to Figure 4 The outer frame 1 is provided with a first cavity 101 and a second cavity 102, which are connected sequentially along a first direction z to form a ventilation cavity 10. An air inlet 103 is provided at the end of the first cavity 101 opposite to the second cavity 102, and an air outlet 104 is provided at the end of the second cavity 102 opposite to the first cavity 101. Along the first direction z, the cross-sectional area of ​​the first cavity 101 is smaller than that of the second cavity 102, and the area of ​​the air inlet end of the outer frame 1 is smaller than that of the air outlet end. This not only helps to save costs but also allows the airflow to diffuse and slow down when it enters the second cavity 102 from the first cavity 101, which helps to improve the coverage and uniformity of the airflow.

[0021] In some embodiments, the first direction z refers to the height direction of the outer frame 1.

[0022] In some embodiments, the cross-sectional area of ​​the first cavity 101 remains essentially unchanged along the first direction z, thereby improving the stability of the air intake.

[0023] In some embodiments, the cross-sectional area of ​​the second cavity 102 gradually increases along the first direction z, so that the airflow gradually diffuses and slows down along the second cavity 102, reducing the risk of turbulence generation.

[0024] In some embodiments, along the first direction z, the cross-section of the ventilation cavity 10 is rectangular, the vertical cross-section of the first cavity 101 is rectangular, and the vertical cross-section of the second cavity 102 is trapezoidal.

[0025] In some embodiments, along the circumference of the outer frame 1, a connecting portion 11 is provided on the outer side wall of the air outlet 104. The connecting portion 11 is used to connect with the mounting base to enhance the stability of the air outlet device 100 installed on the mounting base.

[0026] For the aforementioned guide vane 2, please refer to Figures 1 to 3 The guide member 2 is spaced apart from the inner wall of the ventilation cavity 10 to form a flow channel 20 for airflow between the outer wall of the guide member 2 and the inner wall of the ventilation cavity 10. The guide member 2 includes a guide section 21 and a diverting section 22, which are connected sequentially along a first direction z. The guide section 21 is at least partially located in the first cavity 101 and extends along the first direction z to guide the airflow entering from the first cavity 101 to flow along the first direction z, thereby improving stability. The diverting section 22 is located in the second cavity 102, and the outer wall of the diverting section 22 is parallel to the inner wall of the second cavity 102. When the airflow reaches the second cavity 102, the airflow can smoothly diffuse along the partial flow channel 20 formed by the outer wall of the diverting section 22 and the inner wall of the second cavity 102, forming an adhering flow airflow. This helps to reduce the generation of turbulence, reduce energy loss and noise generation, and make the airflow blown out from the air outlet device 100 more gentle and uniform.

[0027] When the gas from the air inlet 103 side of the air outlet device 100 enters the first cavity 101 from the air inlet 103, it first flows along the first direction z along the first cavity 101, then enters the guide channel 20, and flows along the outer side wall of the guide section 21 of the guide member 2. Then it diffuses and slows down along the outer side wall of the diversion section 22, so as to output a uniform and wide-coverage stable airflow from the air outlet 104 to the external environment.

[0028] In some embodiments, along the first direction z, the two ends of the guide segment 21 are located in the first cavity 101 and the second cavity 102, respectively, to improve the smoothness of the transition of airflow from the first cavity 101 to the second cavity 102.

[0029] In some embodiments, the outer wall of the guide section 21 is connected to the outer wall of the diversion section 22 without gaps, so that the airflow can flow smoothly along the surface of the guide member 2, reducing the risk of airflow leakage or turbulence caused by gaps.

[0030] In some embodiments, the end of the diversion section 22 that is away from the guide section 21 is flush with the air outlet 104.

[0031] In some embodiments, please refer to Figure 2 ,、 Figure 3 and Figure 5 The outer sidewall of the diversion section 22 includes a first sidewall 221, a second sidewall 222, a third sidewall 223, and a fourth sidewall 224. Along the circumference of the outer frame 1, these sidewalls are sequentially connected, forming a triangular prism. The first sidewall 221 and the second sidewall 222 are positioned opposite each other and connected along a second direction x, while the third sidewall 223 and the fourth sidewall 224 are positioned opposite each other along a third direction y. Along the third direction y, one end of the first sidewall 221 and one end of the second sidewall 222 are both connected to the third sidewall 223, and the other ends of the first sidewall 221 and the second sidewall 222 are both connected to the fourth sidewall 224. The connecting edge of the first sidewall 221 and the second sidewall 222 of the second sidewall 222 is connected to the guide section 21. The hollow design of the diversion section 22 helps reduce the weight of the air outlet device 100.

[0032] Among them, the first direction z, the second direction x, and the third direction y are all perpendicular to each other.

[0033] In some embodiments, the second direction x refers to the width direction of the outer frame 1, and the third direction y refers to the length direction of the outer frame 1.

[0034] In some embodiments, the first sidewall 221 and the second sidewall 222 are both parallel to the inner wall of the second cavity 102 to form a straight air outlet channel, reducing the risk of airflow turbulence and helping to reduce noise and improve air outlet uniformity.

[0035] In some embodiments, the distance between the first sidewall 221 and the inner wall of the second cavity 102 is equal to the distance between the second sidewall 222 and the inner wall of the second cavity 102.

[0036] In some embodiments, the third sidewall 223 and the fourth sidewall 224 extend straight along the first direction z.

[0037] In other embodiments, the third sidewall 223 and the fourth sidewall 224 are both parallel to the inner wall of the second cavity 102 to form a straight air outlet channel.

[0038] In some embodiments, the distance between the third sidewall 223 and the inner wall of the second cavity 102 is equal to the distance between the fourth sidewall 224 and the second cavity 102.

[0039] In some embodiments, the flow guide 2 is integrally formed.

The fixing member 31 is connected to one end of the guide section 21 away from the diversion section 22. The two ends of the fixing member 31 along the second direction x are connected to the inner wall of the first cavity 101 to connect the guide member 2 to the outer frame 1.

[0041] In some embodiments, the fixing member 31 and the flow guide 2 are connected by welding. In some examples, the fixing member 31 and the flow guide 2 are connected by argon arc welding or laser welding.

[0042] In some embodiments, when the width of the air outlet side of the outer frame 1 along the second direction x is less than or equal to 200 mm, the fastener 31 is connected to the outer frame 1 by welding. In some examples, the fastener 31 is connected to the outer frame 1 by argon arc welding or laser welding.

[0043] In other embodiments, when the width of the air outlet side of the outer frame 1 along the second direction x is greater than 200 mm, the fastener 31 is detachably connected to the outer frame 1 to improve the maintainability of the air outlet device 100. In some examples, the inner walls of opposite sides of the first cavity 101 along the second direction x are provided with connection holes (not shown). The fixing assembly 3 also includes an elastic element (not shown), with both ends of the fastener 31 engaging with the connection holes along the second direction x, one end of the elastic element being disposed on the fastener 31, and the other end of the elastic element abutting against the edge of a connection hole facing the first cavity 101, so as to detachably connect the fastener 31 to the outer frame 1.

[0044] In some embodiments, an elastic element is disposed at one end of the fixing element 31.

[0045] In some embodiments, the elastic element is configured as a spring, which is sleeved on one end of the fixing member 31. The fixing member 31 has limiting platforms at both ends along the second direction x. The limiting platform at one end of the fixing member 31 abuts against the spring, and the limiting platform at the other end of the fixing member 31 abuts against the edge of the connecting hole.

[0046] In some embodiments, the number of fixing components 3 is multiple, and the multiple fixing components 3 are spaced apart along the third direction y to improve the structural stability of the air outlet device 100.

[0047] In some embodiments, please refer to Figure 2 and Figure 3 The air vent device 100 also includes a decorative panel 4, which is disposed at the end of the diversion section 22 away from the guide section 21. Different patterns can be set on the surface of the decorative panel 4 facing outward to meet the personalized needs of users. The decorative panel 4 is also used to close the port of the diversion section 22 away from the guide section 21 to reduce the risk of airflow turbulence at the air outlet 104 of the air vent device 100.

[0048] In some embodiments, the outer frame 1, the flow guide 2, and the fastener 31 are made of metal or alloy materials, and the trim panel 4 is made of metal, alloy, or plastic materials. In some examples, the outer frame 1, the flow guide 2, and the fastener 31 are made of aluminum alloy profiles.

[0049] In this embodiment, the air outlet device 100 includes an outer frame 1, a flow guide 2, and a fixing component 3. The fixing component 3 connects the flow guide 2 and the outer frame 1. The outer frame 1 is provided with a ventilation cavity 10, which includes a first cavity 101 and a second cavity 102. Along the first direction z, the cross-sectional area of ​​the first cavity 101 is smaller than the cross-sectional area of ​​the second cavity 102. The diffused ventilation cavity 10 increases the coverage and uniformity of the airflow. The flow guide 2 includes a guide section 21 and a diverting section 22. The guide section 21 is at least partially located in the first cavity 101, and the diverting section 22 is located in the second cavity 102. A flow guide channel 20 is formed between the outer wall of the flow guide 2 and the inner wall of the ventilation cavity 10, so that the airflow passing through the ventilation cavity 10 forms an adhering airflow, reducing the generation of turbulence and further improving the uniformity of the airflow.
