Then, by starting the conduit 24, four spaces are divided inside, namely, air temperature, dust, water spray and air pressure. The test environment required by the non-electrical quantity sensor body 27 can be simulated. The conduit 24 and the nozzle 25 are driven to rotate by the environmental simulation device 22, and the nozzle 25 is sequentially used to spray to the surface of the non-electrical quantity sensor body 27 to perform a full range of environmental simulation.

During operation, when the rotating rod 61 rotates, the threaded slide 62 is driven to rotate. Since the threaded slide 62 is limited by the limiting column, the threaded slide 62 is threadedly connected and slides to the bottom, and then squeezes the guide rod 63, so that the guide rod 63 squeezes the slide groove 65 at the bottom to slide to the side end. When the slide groove 65 slides, it drives the cleaning sleeve 66 to slide on the surface of the lighting device 54, so as to clean the lighting device 54 and reduce the accumulation of sand and dust.

Since the upper part of the rotating knocking iron sheet 71 is thin and the bottom is thick, as the threaded slide 62 moves toward the bottom when it rotates, it drives the knocking rod 72 to knock on the top of the rotating knocking iron sheet 71 downward in sequence, and the generated sound changes, so as to detect whether the non-electrical quantity sensor body 27 is accurate under the influence of noise, thereby effectively improving the detection accuracy of the non-electrical quantity sensor body 27.

[0038] Further, such as Figure 6 and Figure 8 As shown, a groove 76 is provided inside the cleaning scraper 75; a clearing ball 78 is slidably connected inside the groove 76; a third spring 77 is fixed to the top of the clearing ball 78, and the other end of the third spring 77 is fixed to the inner wall of the groove 76; during operation, when the cleaning scraper 75 rotates, it drives the clearing ball 78 to rotate, and when it moves to the top of the material guide hole 79, the third spring 77 generates elastic force to push the clearing ball 78 to insert into the material guide hole 79 for squeezing, thereby clearing the blocked sand and dust, thereby reducing the problem of subsequent blockage, and the end of the clearing ball 78 is in a ring shape, thereby reducing the problem of getting stuck inside the material guide hole 79.

[0039] Further, such as Figure 6 and Figure 8 As shown, the inner wall of the collecting box 81 is slidably connected with a circular plate 82; a cleaning rod 83 is fixedly connected to the top of the circular plate 82; a protective head 84 is fixedly connected to the top of the cleaning rod 83; dredging rods 85 are fixedly connected to both sides of the cleaning rod 83 and fit on the inner wall of the guide hole 79; a limiting ring 86 is fixedly connected to the bottom of the circular plate 82; when the cleaning scraper 75 rotates during operation, the dredging ball 78 is driven to rotate, so that when the dredging ball 78 encounters the guide hole 79, it is elastically forced to the bottom by the third spring 77. The cleaning rod 83 is squeezed toward the bottom by squeezing the protective head 84, so that the protective head 84 is squeezed toward the bottom to squeeze the cleaning rod 83, so that the cleaning rod 83 squeezes the circular plate 82 to slide toward the bottom to squeeze the limiting ring 86 to generate elastic force, so that when the cleaning rod 83 slides toward the bottom, it drives the dredging rod 85 to slide inside the guide hole 79 to dredge the blocked sand and dust, thereby reducing the subsequent blockage problem, and with the continuous and uninterrupted squeezing of the dredging ball 78, the cleaning rod 83 shakes through the limiting ring 86 to quickly dredge the sand and dust.

[0040] Further, such as Figure 7 As shown, the end of the sealing cylinder 28 is fixedly connected to the limiting ring 86, and the pull rope 36 passes through the limiting ring 86 and is connected to the ends of the rack 32 and the slide plate 38; when working, by installing the limiting ring 86 on the end of the sealing cylinder 28, the pull rope 36 is limited by the limiting ring 86 when being pulled by the slide plate 38, thereby reducing the problem of shaking and deviation of the pull rope 36.

[0042] Working principle: During operation, when the non-electrical quantity sensor body 27 needs to be tested, the non-electrical quantity sensor body 27 is placed on the top of the environmental simulation cabin 1, and then the driving device 23 is turned on to drive the conduit 24 to rotate, and then the conduit 24 is started to divide the interior into four spaces, namely, air temperature, dust, water spray and air pressure. The test environment required by the non-electrical quantity sensor body 27 can be simulated, and the conduit 24 and the nozzle 25 are driven to rotate by the environmental simulation device 22 to spray to the surface of the non-electrical quantity sensor body 27 through the nozzle 25 in turn, so as to perform a full range of environmental simulation. When the conduit 24 and the nozzle 25 in the dust area rotate, an extrusion device is installed at the bottom. When the plate 37 rotates to the side, it squeezes the slide plate 38 to slide to the side. When the slide plate 38 slides to the side, the pull rope 36 is pulled to make the pull rope 36 pull the rack 32 to slide to the bottom, squeezing the first spring 35 and the second spring 41 to generate elastic force. When the rack 32 slides to the bottom, the gear 31 is engaged, so that the gear 31 drives the shutter piece 29 to rotate inside the window leaf hole to cover the inside of the window leaf hole for sealing, so that when the sand and dust are sprayed out, they are blocked by the shutter piece 29, so that the sand and dust can only be spirally sprayed on the surface of the non-electrical quantity sensor body 27 without overflow. When it is necessary to test the humidity, the sand and dust area is turned away, so that the water spraying area is moved to the end of the sealing cylinder 28, and the non-electrical quantity sensor body 27 is sprayed. The surface of the dusty area is sprayed for testing. When the duct 24 and the nozzle 25 in the dusty area are rotated and moved to the side, since one end of the trapezoidal groove 39 is higher than the other end, when the slide plate 38 slides to the side to a lower position, the slide plate 38 and the trapezoidal groove 39 are separated and staggered from each other, so that the slide plate 38 is pushed by the elastic force generated by the second spring 41 and the first spring 35 to slide the rack 32 upward for reset, so that the louver 29 is rotated to open the window leaf hole, so that the airflow can circulate normally, which is convenient for the subsequent odor and air pressure test of the non-electrical quantity sensor body 27. The device is used for all-round simulation testing, so that the non-electrical quantity sensor body 27 can be quickly detected at one time, thereby improving the detection accuracy and efficiency of the non-electrical quantity sensor body 27. A light box 51 is installed on the top of the sealing tube 28, so that the lighting device 54 inside the light box 51 generates brightness, and then shines on the surface of the refractive lens 55 through the light hole 52 and the light irradiation tube 53, and refracts through the refractive lens 55, so that the light inside the environmental simulation cabin 1 is sufficient to test the performance and detection accuracy of the non-electrical quantity sensor body 27 during the illumination process. When the environmental simulation device 22 rotates, it drives the rotating rod 61 to rotate, so that the sealing rotating plate 56 is driven to rotate, so that the sealing rotating plate 56 covers the surface of the light hole 52 and separates during the rotation process, so that the light irradiated by the light irradiation tube 53 is always in the interval of light and dark and change, so as to test the detection accuracy of the non-electrical quantity sensor body 27 under different illumination;When the rotating rod 61 rotates, it drives the threaded slide 62 to rotate. Since the threaded slide 62 is limited by the limiting column, the threaded connection of the threaded slide 62 slides to the bottom, and then squeezes the guide rod 63, so that the guide rod 63 squeezes the bottom slide groove 65 to slide to the side end. When the slide groove 65 slides, it drives the cleaning sleeve 66 to slide on the surface of the lighting device 54 to clean the lighting device 54 and reduce the accumulation of sand and dust; when the rotating rod 61 is rotating, it drives the knocking rod 72 to rotate, so that when the knocking rod 72 rotates, it knocks on the surface of the rotating knocking iron sheet 71 to produce a sound. Since the upper part of the rotating knocking iron sheet 71 is thin and the bottom is thick, as the threaded slide 62 rotates and moves toward the bottom, it drives the knocking rod 72 to knock The top of the iron sheet 71 is knocked downward in rotation, and the sound produced changes to detect whether the non-electrical quantity sensor body 27 is accurate under the influence of noise, thereby effectively improving the detection accuracy of the non-electrical quantity sensor body 27; when the sealing rotating plate 56 rotates, it drives the connecting rod 73 to rotate, so that the connecting rod 73 drives the cleaning cotton 74 to rotate around the non-electrical quantity sensor body 27 during the rotation process to clean the sand and dust adhered to the surface of the non-electrical quantity sensor body 27 during the test process, thereby improving the detection accuracy of the non-electrical quantity sensor body 27; when the connecting rod 73 rotates, it drives the cleaning scraper 75 to rotate, so that the cleaning scraper 75 can remove the sand and dust accumulated on the surface of the support plate 26 during the rotation process. The dust is rotated to clean, so that the sand and dust flow into the collection box 81 through the opened guide hole 79, and then the sand and dust are collected by the collection box 81; when the cleaning scraper 75 rotates, it drives the dredging ball 78 to rotate, and when it moves to the top of the guide hole 79, the third spring 77 generates an elastic force to push the dredging ball 78 to be inserted into the guide hole 79 to squeeze and dredge the blocked sand and dust, so as to reduce the subsequent blockage problem, and the end of the dredging ball 78 is in a ring shape, so as to reduce the problem of being stuck in the guide hole 79; when the cleaning scraper 75 rotates, it drives the dredging ball 78 to rotate, so that when the dredging ball 78 encounters the guide hole 79, it is squeezed to the bottom by the elastic force generated by the third spring 77 to The surface of the protective head 84 is squeezed so that the protective head 84 is squeezed toward the bottom to squeeze the cleaning rod 83, so that the cleaning rod 83 squeezes the circular plate 82 to slide toward the bottom to squeeze the limiting ring 86 to generate elastic force, so that when the cleaning rod 83 slides toward the bottom, it drives the dredging rod 85 to slide inside the guide hole 79 to dredge the blocked sand and dust, thereby reducing the subsequent blockage problem. With the continuous and uninterrupted squeezing of the dredging ball 78, the cleaning rod 83 is shaken by the limiting ring 86 to quickly dredge the sand and dust. By installing the limiting ring 86 at the end of the sealing cylinder 28, the pull rope 36 is limited by the limiting ring 86 when it is pulled by the slide plate 38, thereby reducing the problem of shaking and deviation of the pull rope 36.By installing a wear-resistant strip 87 on the top of the limiting ring 86, when the pull rope 36 is pulled and slides, the surface of the wear-resistant strip 87 is squeezed, causing the wear-resistant strip 87 to deform and open outward, thereby achieving a protective and wear-resistant effect.
