[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] The present utility model provides as Figures 1-4A stainless steel air nozzle as shown includes an air nozzle body 1. A control structure 2 is arranged in the inner cavity of the air nozzle body 1. The control structure 2 includes a control board 201, a support rod 203 and an adjustment assembly. The control board 201 is movably arranged in the inner cavity of the air nozzle body 1. The control board 201 is used to control the air output volume of the air nozzle body 1. The control board 201 is located in the middle of the inner cavity of the air outlet port of the air nozzle body 1. The support rod 203 is movably inserted through the middle of the control board 201. The support rod 203 is used for the rotational support of the control board 201. The adjustment assembly is arranged at the end of the support rod 203. The adjustment assembly is used to adjust the distance between the support rod 203 and the inner wall of the air nozzle body 1.

[0023] As Figure 1 and Figure 2 shown in, the setting that the control board 201 is located in the middle of the inner cavity of the air outlet port of the air nozzle body 1 enables the air outlet range of the air nozzle body 1 to change with the rotation of the control board 201, so that different air volumes can be controlled according to the air outlet requirements. At the same time, under the rotation of the control board 201, the air outlet angle of the air nozzle body 1 can also be adjusted, thereby improving the diversity of the use of the air nozzle body 1 and strengthening the applicable range and flexibility of the air nozzle body 1. The middle part of the control board 201 is penetrated by the support rod 203, so that the support rod 203 provides effective support for the installation of the control board 201 in the inner cavity of the air nozzle body 1. The control board 201 and the support rod 203 are movably inserted. The control board 201 can rotate flexibly with the support rod 203 as the axis. After rotation, the position can be limited by the extrusion friction between the control board 201 and the inner wall of the air nozzle body 1. Since the support rod 203 is located in the middle of the control board 201, therefore, the control board 201 changes from a parallel state with the inner wall of the air nozzle body 1 to a state with a certain angle. At the same time, the two ends of the control board 201 do not contact the inner wall of the air nozzle body 1 by extrusion. Therefore, when air is discharged, it will be from the space between the two ends of the control board 201 and the air nozzle body 1, so that the two ends of the control board 201 are both subjected to the thrust of the air during air outlet, thereby avoiding the rotation of the control board 201 under the wind force. By using the force balance at both ends after the control board 201 is tilted, the effectiveness of the use of the control board 201 is further improved.

[0024] The adjustment assembly includes an adjustment rod 205 and a spring 206. The spring 206 is fixedly arranged between the adjustment rod 205 and the support rod 203. The adjustment rod 205 is movably inserted through the end of the support rod 203. A positioning suction cup 204 is fixedly arranged at the end of the adjustment rod 205 away from the support rod 203. The positioning suction cup 204 is used for fixing the positions of the adjustment rod 205 and the support rod 203 in the inner cavity of the air nozzle body 1. An external thread is provided on the outer wall of the end of the positioning suction cup 204 facing the adjustment rod 205. A threaded groove is provided at the end of the adjustment rod 205 facing the positioning suction cup 204. The end of the positioning suction cup 204 is threadedly inserted into the inner cavity of the threaded groove.

[0025] As Figure 4 shown in the figure, through the setting of the spring 206, the adjusting rod 205 is movably inserted into the inner cavity of the support rod 203. With the fixed setting of the positioning suction cup 204 and the adjusting rod 205, the support rod 203 can adjust the support height according to the height in the inner cavity of the nozzle body 1, ensuring the effectiveness of the support for the control board 201. At the same time, the positioning suction cup 204 is a plastic suction cup with good adsorption performance. By using the adsorption between the positioning suction cup 204 and the inner wall of the nozzle body 1, it provides structural support for the installation of the support rod 203, and thus also provides convenience for the disassembly and assembly of the support rod 203. Moreover, the positioning suction cup 204 and the adjusting rod 205 can also be disassembled and assembled by threaded rotation. When the positioning suction cup 204 is worn due to the disassembly and assembly of the support rod 203 and the inner wall of the nozzle body 1, the positioning suction cup 204 can be replaced separately, reducing the cost of supporting the control board 201, and further improving the convenience of using the support rod 203 and the adjusting rod 205.

[0026] The control structure 2 further includes two extrusion pads 202, which are respectively fixedly arranged at the bottom end and the top end of the control board 201. The two extrusion pads 202 are both used to limit the position of the control board 201 in the inner cavity of the nozzle body 1. The extrusion pads 202 fixedly arranged on the outer wall of the control board 201 are any one of elastic rubber or elastic silica gel.

[0027] As Figure 2 and Figure 3 shown in the figure, the extrusion pads 202 are respectively fixedly arranged at the top end and the bottom end of the control board 201, so that the control board 201 does not directly rub against the inner wall of the nozzle body 1, improving the safety of using the control board 201. At the same time, it can also increase the frictional resistance with the nozzle body 1 after the control board 201 rotates, thereby strengthening the stability of the position of the control board 201, and further facilitating the extension of the service life of the control board 201 and reducing the use cost of the control board 201. Moreover, the extrusion pads 202 and the control board 201 are adhered by glue. When the extrusion pads 202 are severely damaged due to friction after long-term use, the extrusion pads 202 can be flexibly removed from the control board 201, and then new extrusion pads 202 can be replaced for use on the control board 201, improving the convenience of repeated use of the control board 201, and at the same time reducing the replacement probability of the control board 201, extending the service life of the control board 201, and effectively reducing the use cost of the control structure 2.

[0028] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
