DETAILED DESCRIPTION

[0024] The present invention will be described in more detail below in conjunction with the accompanying drawings. It should be noted that the following description of the present invention with reference to the accompanying drawings is only illustrative and not restrictive. The various embodiments can be combined with each other to form other embodiments not shown in the following description.

[0025] The present invention provides a coaxial asynchronous air outlet structure, referring to Figures 1 to 4 The coaxial asynchronous air outlet structure includes an outer shell 2, an inner shell 4, an air flow adjustment system, and an adjustment member 6. The outer shell 2 has an air inlet and an air outlet, and the inner shell 4 is arranged in the outer shell 2 and forms an air duct with the outer shell; the adjustment member 6 is arranged at the air outlet position and is connected to the air flow adjustment system in the inner shell; one end of the air flow adjustment system is deeply and rotatably arranged in the air duct to adjust the air volume of the air duct. One end of the adjustment member extends out of the air outlet and the outside of the outer shell, and the other end extends into the inner shell and is linked with the adjustment component to drive the adjustment component to rotate. Specifically, the air flow adjustment system includes a first adjustment component, which is connected to the inner shell, and the first adjustment component includes a driving part and a damper, which is rotatably arranged between the inner shell and the outer shell, and the driving part is arranged on the inner shell and is used to drive the damper to rotate, and the damper can be embedded on the outer side of the inner shell (the side facing the outer shell), such as when the air volume in the air duct reaches the maximum, the damper is embedded in the inner shell, and the damper is in a fully open state. It should be understood that the inner shell has a groove or a through hole or a bend or a mating surface that cooperates with the damper to accommodate the damper, so that when the damper is fully opened, the damper is embedded in the inner shell and does not occupy the space of the air duct. Therefore, when the damper is fully opened, the damper is embedded in the inner shell, reducing the flow resistance of the airflow in the air duct.

[0026] Among them, the adjusting part 6 includes a connecting part and a button. The connecting part is connected to the airflow adjustment system and is located in the inner shell 4. The button is located at the air outlet of the outer shell 2. When the air volume and wind direction of the air conditioner need to be adjusted, only the button needs to be pressed to link the airflow adjustment system to adjust the air volume of the air duct. Among them, the connection between the adjusting part 6 and the airflow adjustment system is set in the inner shell 4, and the connecting structure is hidden in the outer shell 2. Only the button is located on the outside, which improves the aesthetic effect of the air outlet structure.

It should be understood that the length of the straight portion 81 on the connecting member 8 should be greater than the width of the adjusting member, so as to provide a path for the adjusting member to slide laterally on the straight portion.

When the adjustment member 6 slides relative to the connecting member 8, the second adjustment component 10 is driven to move to adjust the air volume in the left and right directions of the upper and lower air ducts. The second adjustment component is used to adjust the air volume in the left and right directions of the air duct, and the first adjustment component is used to adjust the air volume in the up and down directions of the air duct.

[0036] That is to say, part 10 of the second adjusting component is located in the upper air duct and the lower air duct and is connected to the adjusting member 6, and is used to adjust the air volume and wind direction circulating in the upper air duct and the lower air duct; part of the first adjusting component 20 is located at the air inlet and is connected to the connecting member 8, and is used to adjust the air volume entering the upper air duct and the lower air duct through the air inlet, thereby realizing the adjustment of the wind direction of the air outlet of the air conditioner.
