[0032] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0033] Reference Figure 1-5 A uniform air outlet structure of a constant temperature and humidity testing machine includes a testing machine body 1. The testing machine body 1 is a constant temperature and humidity testing machine. An adjusting structure 2 is arranged on the testing machine body 1. The adjusting structure 2 is located on the inner wall of the testing machine body 1, and the interior of the adjusting structure 2 is hollow, which is convenient for sending out the air inside the testing machine body 1. The adjusting structure 2 includes a shell 201 arranged on the inner wall of the testing machine body 1. A first motor 202 is installed on the inner wall of the testing machine body 1. The first motor 202 is clamped on the testing machine body 1 to facilitate personnel to disassemble it.

[0034] The output end of the first motor 202 is rotatably connected to the outer wall of the shell 201, and a second rotating plate 203 is installed at the output end of the first motor 202. The side of the second rotating plate 203 adjacent to the first motor 202 is at a certain distance from the inner wall of the shell 201, which effectively avoids the second rotating plate 203 causing certain wear on it during rotation. The inner wall of the second rotating plate 203 is installed with a second motor 204. The second motor 204 is a micro reduction motor, usually composed of a worm gear, a reducer or a gear reducer. The model of the second motor 204 is S-37GR555-540-1218. The size of the micro reduction motor is usually between 3mm and 38mm. Multiple second motors 204 are equidistantly distributed around the circumference of the second rotating plate 203.

[0035] The output end of the second motor 204 is equipped with a fan blade 205, and each output end of the second motor 204 is equipped with a fan blade 205. The side of the fan blade 205 away from the second motor 204 is attached with a first rotating plate 207, and the side of the first rotating plate 207 away from the fan blade 205 is rotatably connected to the inner wall of the housing 201. Each fan blade 205 is equipped with a first rotating plate 207, and the inner wall of the first rotating plate 207 is rotatably connected to a rotating rod 206, and the rotating rod 206 is away from the first rotating plate 207. One side is rotatably connected to the outer wall of the fan blade 205, and the shell 201 is located at the air outlet position of the testing machine body 1. By starting the second motor 204, the output end of the second motor 204 drives the fan blade 205 to rotate, and the fan blade 205 drives the rotating rod 206 to rotate, and the fan blade 205 is adjusted to a suitable angle. When the temperature of the wind is cold or hot, the angle of the fan blade 205 will affect the characteristics of the wind flow, thereby affecting the uniformity of the air outlet. The characteristics of the wind flow can be effectively avoided by adjusting the fan blade 205.

[0036] By starting the second motor 204, the output end of the second motor 204 drives the fan blades 205 to rotate, and the fan blades 205 drive the rotating rod 206 to rotate. After the fan blades 205 are adjusted to a suitable angle, the first motor 202 is started again, and the output end of the first motor 202 drives the second rotating plate 203 to rotate, and the second rotating plate 203 drives the rotating rod 206 to rotate through the fan blades 205. Through the rotation of the second rotating plate 203, the fan blades 205 and the rotating rod 206, the wind inside the testing machine body 1 is output from the air outlet of the testing machine body 1.

[0037] Reference Figure 1 and Figure 3 A protective cover 6 is installed on the side of the shell 201 adjacent to the first motor 202, and the side of the protective cover 6 away from the shell 201 is in contact with the inner wall of the testing machine body 1, and the first motor 202 is located inside the protective cover 6. There is a certain distance between the protective cover 6 and the first motor 202, which is convenient for heat dissipation of the first motor 202. The protective cover 6 is set to avoid erosion of the first motor 202 caused by the interior of the testing machine body 1. A breathable plate 8 is provided on the side of the testing machine body 1 adjacent to the first motor 202, and the breathable plate 8 provided on the testing machine body 1 is in contact with the first motor 202, and the first motor 202 is further cooled by the breathable plate 8.

[0038] The outer wall of the shell 201 is threadedly connected with a bolt 7, and the outer wall of the bolt 7 is threadedly connected to the inner wall of the testing machine body 1. There are four bolts 7, which are symmetrically distributed at the four corners of the shell 201 to improve the connection effect between the shell 201 and the testing machine body 1. The set bolts 7 make it convenient for personnel to install and disassemble the shell 201.

[0039] Reference Figure 2 and Figure 6 A reinforcing structure 3 is provided on the testing machine body 1, and the reinforcing structure 3 includes a first pulley 303 rotatably connected to the air outlet of the testing machine body 1, and the two first pulleys 303 are symmetrically distributed with the air outlet of the testing machine body 1 as the center, and the outer wall of the first pulley 303 is transmission-connected with a belt 305, and a first connecting plate 304 is installed on the side of the first pulley 303 away from the belt 305, and both ends of the first connecting plate 304 are respectively installed on the two first pulleys 303, and the two first pulleys 303 are both rotationally connected to the testing machine body 1, and the other two first pulleys 303 are transmission-connected with the same belt 305.

[0040] The inner wall of the belt 305 is transmission-connected to a second pulley 306, and the outer wall of the second pulley 306 is rotationally connected to the air outlet of the testing machine body 1. Multiple second pulleys 306 are equidistantly and symmetrically distributed on the testing machine body 1, and are transmission-connected to the inner wall of the first pulley 303. A second connecting plate 307 is installed on the side of the second pulley 306 away from the belt 305. There are six second connecting plates 307, and a second pulley 306 is installed at both ends of each second connecting plate 307.

[0041] A square groove 308 is provided on the testing machine body 1, and a round rod 301 is rotatably connected to the square groove 308 provided on the testing machine body 1. The round rod 301 is located at the center of the square groove 308 provided on the testing machine body 1, and one end of the round rod 301 is fixedly connected to the outer wall of the first pulley 303, and the left end of the round rod 301 is rotatably connected to the inner wall of the testing machine body 1 and fixedly connected to the outer wall of the first connecting plate 304. A turntable 302 is installed on the outer wall of the round rod 301, and an anti-slip groove is provided on the surface of the turntable 302 to facilitate operation by personnel without falling out of their hands.

[0042] By rotating the turntable 302, the round rod 301 is driven to rotate, the round rod 301 drives the first pulley 303 to rotate, the first pulley 303 drives the belt 305 to transmit, the belt 305 drives the second pulley 306 to transmit, and the first pulley 303 and the second pulley 306 are set to adjust the angle of the first connecting plate 304 and the second connecting plate 307. The air outlet angle is upward and the filter plate 4 slides about 5 degrees, which can effectively achieve the effect of uniform air outlet. Because the air will be affected by gravity when flowing in the air duct of the test machine body 1, when the air outlet angle is upward, the air can be better discharged from top to bottom Flow, thereby forming a uniform airflow in the test machine body 1. At the same time, since hot air is lighter than cold air, it will naturally rise. When the air outlet is upward, the hot air can flow from top to bottom better, making the temperature distribution in the test machine body 1 more uniform. When the test machine body 1 is no longer in use, the turntable 302 can be rotated to drive the first connecting plate 304 and the second connecting plate 307 to adjust the angle, and the first connecting plate 304 and the second connecting plate 307 can be adjusted to the same vertical horizontal plane to achieve the effect of closing the air outlet of the test machine body 1, thereby effectively preventing dust from entering the inside of the test machine body 1.

[0043] Reference Figure 2 and Figure 4 The air outlet of the testing machine body 1 is provided with a sliding opening 5, and the sliding opening 5 provided on the testing machine body 1 is located below the second connecting plate 307. When the temperature of the wind blown out by the testing machine body 1 is different from that of the external environment, condensation water may be generated at the air outlet of the testing machine body 1 due to the temperature drop. The sliding opening 5 provided on the testing machine body 1 is conducive to the discharge of condensation water, which effectively avoids water accumulation in the testing machine body 1 and causes certain impact on the testing machine body 1.

[0044] A filter plate 4 is installed on one side of the shell 201 adjacent to the test machine body 1. The filter plate 4 is located inside the air outlet of the test machine body 1. The filter plate 4 is at a certain distance from the second connecting plate 307, and the filter plate 4 can improve the uniformity of the air outlet in some cases. When the airflow passes through the filter plate 4, it can generate a certain resistance, so that the airflow is dispersed and flows evenly in all directions when passing through. This dispersion effect can make the airflow more evenly distributed, thereby improving the uniformity of the air outlet. In addition, when the airflow passes through the filter plate 4, larger particles will be blocked on the surface of the filter plate 4 or adsorbed on the filter plate 4, while smaller particles will be dispersed and removed by the holes on the filter plate 4, thereby making the air outlet purer and more uniform.

[0045] Working principle:

[0046] By starting the second motor 204, the output end of the second motor 204 drives the fan blades 205 to rotate, and the fan blades 205 drive the rotating rod 206 to rotate. After the fan blades 205 are adjusted to a suitable angle, the first motor 202 is started again, and the output end of the first motor 202 drives the second rotating plate 203 to rotate, and the second rotating plate 203 drives the rotating rod 206 to rotate through the fan blades 205. The wind inside the testing machine body 1 is sent out from the air outlet of the testing machine body 1 through the rotation of the second rotating plate 203, the fan blades 205 and the rotating rod 206. By effectively and evenly sending out the wind, the stability of the wind speed and wind direction is improved, and the test sample can be effectively prevented from being locally overheated or over-humidified due to the instability of the wind speed and wind direction, thereby effectively improving the accuracy and reliability of the test results.

[0047] By rotating the turntable 302, the round rod 301 is driven to rotate, the round rod 301 drives the first pulley 303 to rotate, the first pulley 303 drives the belt 305 to transmit, the belt 305 drives the second pulley 306 to transmit, and the first pulley 303 and the second pulley 306 are provided to adjust the angle of the first connecting plate 304 and the second connecting plate 307. By adjusting the connecting plates, changing the angle of the air outlet can not only effectively achieve the effect of uniform air outlet, but also avoid blowing directly to the human body, thereby reducing discomfort.

[0048] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
