[0034] The guide structure 5 includes a connecting cover 501 fixedly installed at the lower end of the sprinkler head 404, a plurality of connecting rods 502 equidistantly distributed in a circle are fixedly installed on the inner side of the connecting cover 501, a connecting ring 503 is fixedly connected to the lower end of the connecting rod 502, the connecting ring 503 facilitates the downward flow of clean water, a sleeve ring 504 is movably sleeved on the outer side of the connecting ring 503, and the connection between the sleeve ring 504 and the connecting ring 503 is a rotating connection.

[0035] A plurality of guide plates 505 equidistantly distributed in a circle are fixedly mounted on the upper end of the collar 504, and the plurality of guide plates 505 are distributed on the outer side of the connecting cover 501, and the shape of the guide plates 505 is arc-shaped, and the arc-shaped guide plates 505 can allow clean water to rinse the inner top surface of the test box 1, and a reinforcement ring 506 is fixedly sleeved on the outer side of the plurality of guide plates 505, and a gear ring 507 is fixedly sleeved on the outer side of the collar 504, and a rack 508 is mounted on the outer side of the gear ring 507, and the rack 508 is fixedly connected to the retaining bar 403 through a plurality of rectangular rods.

[0036] Working principle: When it is necessary to flush the internal structure of the test box 1, the personnel turns on the water pump connected to the end of the conduit 405, so that the spray head 404 sprays clean water inside the test box 1, and at the same time drives the motor 408 to drive the worm 407 to rotate, and the rotation of the worm 407 drives the reciprocating screw 401 to rotate through the turbine 406, and the rotation of the reciprocating screw 401 drives the slider 402 to drive the spray head 404 to move back and forth inside the test box 1, so that the spray head 404 flushes the inside of the test box 1 in a large range;

[0037] When the shower head 404 sprays clean water, most of the clean water falls through the connecting ring 503, and a part of the clean water rushes upward through the multiple arc-shaped guide plates 505. In the process of the shower head 404 reciprocating left and right, the rack 508 drives the ring 504 and the multiple guide plates 505 to rotate through the gear ring 507, so that the multiple upward water columns can rotate to flush the top surface of the interior of the test box 1, so that the interior of the test box 1 can be cleaned more thoroughly.

[0038] Example 2: Please refer to Figure 4 , Figure 7 , Fig. 9 , this embodiment further explains the first embodiment, the material holding structure 6 includes a material tray 601 that can move up and down inside the test box 1, the material tray 601 is made of a perforated plate, the lower end of the material tray 601 is movably abutted against two symmetrically distributed support rails 602, the lower end of the material tray 601 is fixedly connected to two symmetrically distributed rollers 603, and the rollers 603 are in rolling contact with the support rails 602 through limiting straight grooves, the material tray 601 can be moved out of the test box 1 through the rollers 603, so as to facilitate material placement and retrieval, a connecting seat 604 is fixedly installed at the center of the side where the two support rails 602 are away from each other, a sliding rod 605 is installed on the left side of the material tray 601, and the sliding rod 605 is fixedly connected to the test box 1, and the connecting seat 604 on the left side is movably sleeved on the outer side of the sliding rod 605.

[0039] A threaded rod 606 is installed on the right side of the material tray 601, and the threaded rod 606 is fixedly connected to the worm 407. A threaded tube 607 is threadedly sleeved on the outer side of the threaded rod 606, and the threaded tube 607 is movably embedded in the inside of the right connecting seat 604. The cross-sectional shape of the threaded tube 607 is in the shape of an "I". The outer side of the threaded tube 607 is located inside the connecting seat 604 and is movably embedded with a plurality of pins 608 equidistantly distributed around the circumference. A hemispherical portion is provided at one end of the pin 608 close to the threaded tube 607, and the hemispherical portion of the pin 608 can reduce the friction resistance between the pin 608 and the threaded tube 607.

[0040] The connection between the hemispherical part of the pin rod 608 and the threaded tube 607 is a movable clamping connection. The end of the pin rod 608 away from the threaded tube 607 is fixedly connected with a gasket 609. The side of the gasket 609 away from the threaded tube 607 is movably abutted with a spring 610, and the end of the spring 610 away from the gasket 609 is movably abutted with the connecting seat 604. A plurality of limiting pillars 9 are fixedly installed on the inner bottom surface of the test box 1, and the connection between the material tray 601 and the limiting pillars 9 is a movable abutment. A retaining ring 10 is fixedly sleeved on the outer side of the threaded rod 606, and the upper end surface of the threaded tube 607 can be movably abutted with the lower end surface of the retaining ring 10, and the retaining ring 10 can limit the upward position of the material tray 601.

[0041] In this embodiment: when the driving motor 408 drives the worm 407 to rotate, the threaded rod 606 will also rotate accordingly. During the rotation of the threaded rod 606, the hemispherical parts of the plurality of pins 608 are embedded in the hemispherical grooves on the outside of the threaded tube 607 under the drive of the spring 1 610, so that the threaded tube 607 is positioned so that the threaded tube 607 cannot rotate inside the connecting seat 604. Therefore, when the threaded rod 606 rotates, the material tray 601 can be driven to move downward through the threaded tube 607. After 601 moves down and hits the limit support 9, the connecting seat 604 cannot move down further. At this time, under the action of greater resistance, the hemispherical part of the pin rod 608 will repeatedly rotate in and out of the hemispherical groove outside the threaded tube 607, and the threaded tube 607 will rotate together with the threaded rod 606, that is, the threaded tube 607 idles inside the connecting seat 604. After the spray head 404 flushes the inside of the test box 1 for a period of time, the material tray 601 can be completely immersed in clean water, which can avoid dead corners of the material tray 601 during flushing.

[0042] Example 3: Please refer to Figure 4 , Figure 7 , Figure 8 , this embodiment further explains the second embodiment, the driving structure 7 includes a bevel gear 1 701 fixedly sleeved on the outside of the threaded rod 606, and the bevel gear 1 701 is close to the inner bottom surface of the test box 1, and the outer side of the bevel gear 1 701 is matched with a bevel gear 2 702, and the interior of the test box 1 is rotatably installed with a rotating shaft 703 near its lower end through a sealed bearing, the positioning shaft of the bevel gear 2 702 and the right end of the rotating shaft 703 are fixedly sleeved with a synchronous wheel 704, and the outer side of the synchronous wheel 704 is matched with a synchronous belt 705, and a plurality of ejector rods 706 are installed on the outer side of the rotating shaft 703, and a plurality of equally spaced stoppers 707 are fixedly installed at the lower end of the material tray 601, and the connection between the ejector rod 706 and the stopper 707 is a movable abutment, and the ejector rod 706 can drive the material tray 601 to move through the stopper 707.

[0043] An extrusion assembly 8 is installed at the front end of the material tray 601, and the extrusion assembly 8 is close to the inner bottom surface of the test box 1. The extrusion assembly 8 includes a push plate 801 that is movably abutted against the material tray 601, and the side of the push plate 801 close to the material tray 601 is an arc surface. The arc surface of the push plate 801 can reduce the downward resistance of the material tray 601. A plurality of telescopic rods 802 distributed at equal distances are fixedly installed on the side of the push plate 801 away from the material tray 601, and a spring 2 803 is movably sleeved on the outer side of the telescopic rod 802, and the two ends of the spring 2 803 are respectively movably abutted against the test box 1 and the push plate 801.

[0044] In this embodiment: during the rotation of the threaded rod 606, the threaded rod 606 drives the rotating shaft 703 to rotate through the bevel gear 1 701, the bevel gear 2 702, the synchronous wheel 704 and the synchronous wheel 705, and the rotation of the rotating shaft 703 drives the multiple push rods 706 to rotate. When the material tray 601 moves down and abuts against the limiting pillar 9, the push rod 706 will abut against the block 707 during the rotation process, and push the material tray 601 forward through the block 707. The forward movement of the material tray 601 will compress the spring 2 803. When the push rod 706 rotates and disengages from the block 707, the material tray 601 will instantly move back and hit the rear side wall of the test box 1 driven by the compressed elastic force of the spring 2 803. In this way, the material tray 601 is immersed in the bottom of the test box 1 and swings back and forth, which is conducive to allowing the water flow to fully flush the gap of the material tray 601;

[0045] After the internal structure of the test box 1 is flushed, the driving motor 408 drives the worm 407 and the threaded rod 606 to rotate in the opposite direction. At this time, the hemispherical portion of the pin 608 will be re-embedded in the hemispherical groove outside the threaded tube 607 to position the threaded tube 607, so that the threaded rod 606 rotates in the opposite direction to drive the material tray 601 to move up and reset.

[0046] Example 4: Please refer to Figure 8 This embodiment further explains the second embodiment. The lower end of the material tray 601 is located on the rear side of the roller 603 and is fixedly installed with an extension block 11, and the extension block 11 is located inside the support rail 602. The extension block 11 and the support rail 602 are attached to each other on one side and are fixedly embedded with a magnetic block 12. The extension block 11 is movably magnetically attracted to the rear end of the support rail 602 through the magnetic block 12.

[0047] In this embodiment: after the material tray 601 is pulled out of the test box 1 to take out the material, the material tray 601 is pushed back into the test box 1, and the extension block 11 will move with the material tray 601. When the material tray 601 completely enters the test box 1, the magnetic block 12 on the extension block 11 will absorb the magnetic block 12 at the rear end of the support rail 602, which can effectively prevent the material tray 601 from being displaced during the subsequent up and down reciprocating movement inside the test box 1.
