[0017] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0019] In the description of this application, unless otherwise expressly defined, terms such as "setup," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this application in conjunction with the specific content of the technical solution.

[0020] The following is combined with Figures 1 to 6 The embodiments of this utility model are described below.

[0021] This application provides a nozzle assembly, which includes a housing 100, a windshield 200 and a fastener 300, wherein the housing 100 has an air outlet chamber 104, and the air outlet chamber 104 has an air inlet 101 and an air outlet 102 that are interconnected. The windshield 200 is rotatably connected to the air outlet 102, and the windshield 200 is provided with a rotating groove 201 on the outer side; The fastener 300 is slidably connected to the rotating groove 201, and one end of the fastener 300 passes through the rotating groove 201 and is connected to the housing 100, so as to adjust the air volume of the air outlet 102 by means of the fastener 300 and the windshield 200.

[0022] When it is necessary to adjust the airflow, for example, the wind deflector 200 is rotatably connected to the housing 100 via a pivot. First, loosen the fastener 300. At this time, the wind deflector 200 can rotate around the housing 100 to adjust its angle. During adjustment, the fastener 300 slides within the rotating groove 201 on the outer side of the wind deflector 200. After adjusting to the desired angle, tighten the fastener 300 to fix the wind deflector 200 in that position, thereby changing the effective opening area of ​​the air outlet 102 and realizing the adjustment of the airflow.

[0023] By providing a wind deflector 200 and fasteners 300, the wind deflector 200 can rotate around the housing 100 when the fasteners 300 are loosened, so as to adjust the angle of the wind deflector relative to the air outlet. After adjustment, it is fixed by the fasteners, thereby changing the air volume of the air outlet. The structure is simple and the adjustment is convenient.

[0024] Therefore, it enables rapid and continuous adjustment of the airflow, is simple to operate, and requires no complicated tools. It also improves the applicability of the nozzle assembly, enabling it to adapt to airflow variations required by different processes.

[0025] In some embodiments, the housing 100 is divided into two air outlet chambers 104 by a guide ramp 103, thereby forming a structure with two dispersed air outlets 102 on the left and right. Each air outlet chamber 104 is provided with a wind deflector 200 and a plurality of fasteners 300 at the corresponding air outlet 102. For example, Figure 3 The diagram illustrates an airflow direction after air intake. Air enters the housing 100 through the air inlet 101, encounters the guide ramp 103, and is evenly distributed into two independent air outlet chambers 104, subsequently flowing out from the left and right air outlets 102 respectively. Each air outlet 102 is equipped with an independent wind deflector 200 and fastener 300. During operation, the fastener 300 on one side can be loosened individually to adjust the angle of the wind deflector 200 on that side, thereby independently controlling the airflow volume of the left and right air outlets 102. This is suitable for application scenarios where different airflow settings may be required on both sides.

[0026] When external air flows to the air outlet 102, it is easy to form vortices inside due to the sudden change in the size of the ventilation cross-sectional area through which the fluid passes, which affects the air outlet effect. Optionally, the cross-section of the guide slope 103 is an inverted V shape. The function of the slope is to guide the airflow, so that the air velocity is evenly distributed when the air is introduced, preventing the formation of vortices inside the housing 100 and improving the air outlet efficiency.

[0027] In some embodiments, the fastener 300 is a bolt or a wing bolt, and the housing 100 has a threaded hole. When the fastener 300 is a wing bolt, one end of the wing bolt passes through the rotating groove 201 and is threadedly connected to the threaded hole. During adjustment, the wing bolt is loosened or tightened by hand, allowing it to slide within the rotating groove 201 of the windshield 200. When loosened, the windshield 200 can rotate freely; when tightened, the bolt is secured to the threaded hole on the housing 100, fixing the windshield 200 in place. This ensures that the windshield 200 remains stable after adjustment, while also facilitating manual operation and convenient adjustment without the need for additional adjustment tools.

[0028] In some embodiments, the interior of the wind deflector 200 is divided into multiple independent airflow guiding chambers 202 along its length. Adjacent airflow guiding chambers 202 are separated by baffles 205. Specifically, the interior of the wind deflector 200 is divided into multiple independent airflow guiding chambers 202 along its length by baffles 205. Each chamber forms an air outlet area, allowing air to enter the wind deflector 200 from the air outlet 102 and then enter the multiple independent airflow guiding chambers 202, before being blown out from the air outlet areas of each chamber. Each airflow guiding chamber 202 is equipped with a rotatable adjusting blade 400. By rotating the adjusting blade 400, each airflow guiding chamber 202 acts as an independent air duct. The angle of the adjusting blade 400 controls the size of the air outlet gap 107 in that air outlet area. A larger air outlet gap 107 results in a larger airflow volume; conversely, a smaller airflow volume results in a smaller airflow volume, thus achieving regional airflow adjustment. Therefore, by changing the size of the air outlet gap 107 between the adjusting blade 400 and the wind deflector 200, the air outlet volume of the chamber can be adjusted, thereby controlling the air outlet volume of different areas to meet different coating process requirements.

[0029] Optionally, the nozzle assembly further includes multiple adjusting blades 400, each of which is rotatably disposed within a flow guide chamber 202. Each adjusting blade 400 and the wind deflector 200 form an air outlet gap 107. That is, each adjusting blade 400 is respectively disposed on a corresponding flow guide chamber 202, and the adjusting blade 400 and the wind deflector 200 are rotatably connected to form an air outlet gap 107 that adjusts the size of the air outlet 102. By rotating the adjusting blade 400, the size of the air outlet gap 107 in the corresponding flow guide chamber 202 can be adjusted, thereby achieving zoned adjustment of the airflow in different air outlet areas. Therefore, by adding adjusting blades 400 to the multiple flow guide chambers 202, the airflow in each area can be more precisely adjusted to adapt to different coating materials and process requirements.

[0030] In some embodiments, a rotating shaft 203 is rotatably connected inside the windshield 200, and the adjusting blade 400 is rotatably connected to the windshield 200 via the rotating shaft 203. Specifically, one end of the adjusting blade 400 is welded and fixed to the rotating shaft 203, which provides a stable rotation fulcrum, ensuring smooth rotation of the adjusting blade 400. Therefore, the overall structure is simple, the adjusting blade 400 rotates smoothly, the risk of jamming is reduced, and individual adjustment of multiple blades is facilitated, improving adjustment efficiency.

[0031] In some embodiments, an adjusting member 500 is further included for driving the adjusting blade 400 to rotate. The adjusting member 500 is disposed outside the windshield 200 and is connected to the adjusting blade 400. The windshield 200 is provided with a connecting groove 204, and the adjusting member 500 can move along the connecting groove 204. By rotating the adjusting member 500, the adjusting member 500 drives the rotating rod 401 to rotate, thereby changing the size of the air outlet gap 107 between the adjusting blade 400 and the windshield 200. This allows for independent adjustment of the airflow volume of each guide chamber 202, further improving the flexibility and accuracy of airflow adjustment.

[0032] In some alternative embodiments, the adjusting element 500 is a wing nut, and a rotating rod 401 with external threads is fixed on the adjusting blade 400. The wing nut and the rotating rod 401 are threaded together. By turning the wing nut, the rotating rod 401 is driven to rotate, thereby causing the adjusting blade 400 to rotate. When the operator turns the wing nut, the rotating rod 401 is driven to rotate through the thread transmission, thereby causing the adjusting blade 400 to rotate and adjusting the air outlet gap 107, thus realizing independent adjustment of each adjusting blade 400.

[0033] In some embodiments, one side of the windshield 200 is rotatably connected to the housing 100 via a hinge 600. Specifically, when the fastener 300 is loosened, the windshield 200 rotates about the hinge 600 axis, changing its angle; when the fastener 300 is tightened, the windshield 200 remains fixed. Thus, the hinge 600 provides a rotatable connection point, allowing the windshield 200 to rotate around it, facilitating angle adjustment. Optionally, one side of the windshield 200 can rotate relative to the housing 100 via a hinge, thereby adjusting the angle of the windshield 200 and facilitating installation and disassembly.

[0034] In some embodiments, the bottom of the housing 100 is provided with a return air hole 105 and a return air chamber for returning air. The return air hole 105 communicates with the return air chamber 106, which is separated from the outlet air chamber 104. After some air is blown out from the outlet 102, it enters the return air chamber 106 through the return air hole 105 at the bottom of the housing 100. The return air chamber 106 is separated from the outlet air chamber, allowing some air to be recycled or discharged, maintaining the balance of airflow within the oven. After returning, the air can be guided back to the system or the outside through the return air chamber 106. This helps maintain stable airflow within the oven, reduces energy loss, and minimizes interference of the return air with the intake air.

[0035] This application also provides a coating machine oven, which includes the nozzle assembly disclosed in any of the above embodiments. Since the coating machine oven uses the nozzle assembly disclosed in the embodiments of this application, the coating machine oven has the technical advantages of the nozzle assembly disclosed in the embodiments of this application. During use, the overall or local air volume can be adjusted according to the coating process requirements, making the operation flexible and adaptable to the air volume requirements of different coating processes.

Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention, and these equivalent modifications or substitutions are all included within the scope defined by the claims of the present disclosure.
