[0004] The prior art patent document with publication number CN215627162U provides a water circulation system for a high and low temperature humidity test chamber. The water generated during the humidification operation of the humidifier main body of the circulation system is discharged through a drain port. The setting of the condensation plate facilitates the condensation of the humidified water. The condensed water is filtered through the filter mesh, filter cotton and nanofiltration membrane in the filter tube main body. The filtered water flows into the water tank, and the treated water is transported to the humidifier main body through the circulation pipe and the water pump to achieve recycling.

[0005] In the above-mentioned prior art, although the circulation system filters the condensed water through the cooperation of the filter screen, filter cotton and nanofiltration membrane in the filter tube body, and the filtered water flows into the water tank for recycling, the filter screen and other filtering mechanisms in the water circulation system of the patented technology are very troublesome to clean. The staff is required to disassemble the entire filtering mechanism, and then disassemble the filter screen, filter cotton and nanofiltration membrane separately, and finally clean them, which increases the cleaning difficulty of the staff. Therefore, we need a high and low temperature and humidity test chamber water circulation system. Utility Model Content

[0029] Through the above technical solution, by starting the motor 401, the screw rod 402 can be rotated and the lifting block 403 can be driven to move relatively, and then the connecting plate 406 on the connecting shaft 405 is pushed to move through the movable plate 404. The connecting plate 406 moves to pull most of the filter screen 407 out of the water outlet pipe 3. The staff only needs to open the box door on the box body 2 and then directly clean the filter screen 407. After cleaning, the screw rod 402 is rotated in the opposite direction to allow the filter screen 407 to be inserted into the card slot 408 for installation.

[0037] Through the above technical solution, it is convenient for the connecting shaft 405 to move and drive the connecting plate 406 to move, so that the filter screen 407 on one side of the connecting plate 406 can move. The filter screen 407 moves out to facilitate the staff to clean it, and the block set on one side of the filter screen 407 can limit it to prevent the filter screen 407 from directly detaching from the water outlet pipe 3, and a sealing ring is set at the connection between the filter screen 407 and the water outlet pipe 3, so that the sealing between the filter screen 407 and the water outlet pipe 3 is improved.

[0038] Specifically, the connecting frame 801 forms a sliding structure with the connecting block 802 through the movable groove 803 , and the shape and size of the inner wall of the movable groove 803 match the shape and size of the bottom of the connecting frame 801 .

[0042] Working principle: When using the high and low temperature humidity test chamber water circulation system, first, when cleaning the filter 407, first open the box door on the box body 2, and then start the motor 401, the motor 401 drives the screw rod 402 to rotate, the screw rod 402 drives the lifting block 403 to move up and down, because the threads on both sides of the screw rod 402 rotate in opposite directions, the two lifting blocks 403 are relatively lifted, the lifting blocks 403 drive the movable plate 404 to rotate, the two movable plates 404 rotate relative to each other to push the connecting plate 406 on the connecting shaft 405 to move, and then the connecting plate 406 drives the filter 407 to move outward, and the staff can reach into the box body 2 through tools to clean the filter 407. After cleaning, After completion, the motor 401 is rotated in the reverse direction so that the connecting plate 406 pushes the filter screen 407 back to the slot 408 in the water outlet pipe 3 for connection. When the test box is moved, the universal wheel 804 on the test box base 1 can enable it to move, because the movable slot 803 at the bottom of the connecting frame 801 can enable the connecting block 802 to move to a certain extent, and then during the movement of the universal wheel 804, the vibration can be buffered to a certain extent through the action of the spring 805 and the damper 806 to prevent the vibration from affecting the equipment in the test box when encountering a rugged road. This completes all the work. The content not described in detail in this manual belongs to the existing technology known to professional and technical personnel in this field.
