DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] like Figure 1-Figure 11 As shown, a water-washing humidifier function test device comprises a test bench 1 and a controller 2 arranged at one side of the test bench 1, a charging line 3 for power-on detection of the humidifier is connected to one side of the controller 2, the interior of the test bench 1 is in a cavity shape, two slide grooves 5 are symmetrically provided at the upper end of the test bench 1, and movable supporting blocks 6 are slidably provided inside the two slide grooves 5, and a driving component for driving the two movable supporting blocks 6 to move synchronously is provided inside the test bench 1;

[0040] The driving assembly includes a moving seat 12 and a screw rod 10 rotatably arranged inside the test bench 1. A motor 4 for driving the screw rod 10 to rotate is arranged on the outer side of the test bench 1. The motor 4 is electrically connected to the controller 2. A guide block 41 is fixedly arranged on the upper end of the moving seat 12 for slidingly cooperating with the inner top surface of the test bench 1. An internal threaded sleeve 18 for threadedly cooperating with the screw rod 10 is rotatably provided through the middle of the moving seat 12. A fixed plate 13 is respectively arranged at the lower end of the two moving supporting blocks 6. Constraint grooves 38 for vertically sliding cooperating with the moving seat 12 are opened on the surfaces of the two fixed plates 13. Limiting members for limiting the rotation of the internal threaded sleeve 18 and cooperating with the constraint grooves 38 are respectively arranged on both sides of the moving seat 12. A clamping member cooperating with the two fixed plates 13 is arranged in the middle of the inner bottom surface of the test bench 1. A transmission member is arranged at one end of the outer surface of the internal threaded sleeve 18. When in use, the staff first places the humidifier to be tested on the detection area in the middle of the test bench 1 (refer to the attached manual). Figure 1 , that is, the middle position of the test bench 1), the motor 4 drives the screw rod 10 to rotate, the rotation of the screw rod 10 drives the moving seat 12 to move, the movement of the moving seat 12 drives the two moving supporting blocks 6 to move synchronously, when the two moving supporting blocks 6 move to the middle position of the test bench 1, the limiter releases the rotation restriction on the internal threaded sleeve 18, that is, the continued rotation of the screw rod 10 will not drive the moving seat 12 to move.

[0041] Furthermore, the limiting member includes a first pressure block 23 and a first mounting groove opened on one side of the movable seat 12. The depth values ​​at the upper and lower ends of the constraint groove 38 are less than the depth value at the middle of the constraint groove 38. One side of the first pressure block 23 is connected to the first mounting groove through a first spring 22. A first clamping rod 21 is fixedly provided on one side of the first pressure block 23. A first clamping hole 24 matching the first clamping rod 21 is provided on the outer surface of the internal threaded sleeve 18. The limiting member described above releases the rotation restriction on the internal threaded sleeve 18, that is, the first clamping rod 21 is disengaged from the first clamping hole 24 under the action of the first spring 22 resetting. At this time, the internal threaded sleeve 18 is released from the restriction, that is, the screw rod 10 will drive the internal threaded sleeve 18 to idle.

[0042] Furthermore, the clamping member includes a fixed shell 11 fixed to the inner bottom surface of the test bench 1 and wedge-shaped limit blocks 16 symmetrically movable and penetrating through the two ends of the fixed shell 11. The two wedge-shaped limit blocks 16 are connected by a connecting spring 20. The lower end of the movable seat 12 is symmetrically provided with two extrusion plates 15 for extruding the wedge-shaped limit blocks 16 to slide into the fixed shell 11. The middle parts of the two extrusion plates 15 are provided with notches that match the extrusion plates 15. The lower ends of the two fixed plates 13 are provided with limit grooves 37 that match the wedge-shaped limit blocks 16. When the two movable supporting blocks 6 move synchronously to the middle position of the test bench 1, first, one end of the extrusion plate 15 squeezes the wedge surface of the wedge-shaped limit block 16, which will cause the wedge-shaped limit block 16 to slide into the fixed shell 11. When the notch of the extrusion plate 15 matches the notch of the notch, the wedge-shaped limit block 16 will slide into the fixed shell 11. After the wedge-shaped limit block 16 is aligned, the wedge-shaped limit block 16 slides outward under the reset action of the connecting spring 20, and further passes through the notch to get into the limit groove 37. Under the extrusion action of the wedge-shaped limit block 16, the fixed plate 13 moves upward, so that the extrusion of the first pressure block 23 by the upper end of the constraint groove 38 under the gravity of the fixed plate 13 is released, that is, the first clamping rod 21 described in the previous paragraph is disengaged from the first clamping hole 24 under the reset action of the first spring 22, and at the same time, the limit groove 37 of the fixed plate 13 maintains cooperation with the wedge-shaped limit block 16, effectively limiting the movement of the fixed plate 13, that is, limiting the movement of the movable seat 12, so that the rotation of the screw rod 10 will continuously drive the internal threaded sleeve 18 to rotate idly.

[0043] Furthermore, the transmission member includes a winding sleeve 17 rotatably sleeved on the outside of the internal threaded sleeve 18 and two pull ropes 14 respectively wound around the outer surface of the winding sleeve 17. A second clamping rod 25 is movably penetrated through the side wall of the internal threaded sleeve 18. A second clamping hole matching the second clamping rod 25 is provided on the inner wall of the winding sleeve 17. A second pressure block 27 is provided at one end of the second clamping rod 25. The second pressure block 27 is connected to the internal threaded sleeve 18 through a second spring 26. Two side slideways 36 matching the second pressure block 27 are symmetrically provided on the surface of the screw rod 10. Through grooves 35 that are interconnected are respectively provided at both ends of the two side slideways 36. Connecting bodies that are connected and cooperated with the movable supporting block 6 for synchronous movement are respectively slidably provided on the inner bottom surface of the test bench 1. One end of the two pull ropes 14 movably penetrates the fixed plate 13 and is fixedly connected to the connecting body. The internal threaded sleeve 18 is idling. When the second clamping rod 25 is engaged with the second clamping hole, the internal threaded sleeve 18 drives the winding sleeve 17 to rotate synchronously, and the winding sleeve 17 rotates to reel in the two pull ropes 14. The reeling in of the pull rope 14 will make the pull rope 14 gradually tighten. In the process of tightening and straightening the pull rope 14, the fixed plate 13 will move upward further. The upward movement of the fixed plate 13 will cause the lower end of the constraint groove 38 to squeeze the first pressure block 23, preparing for the first clamping rod 21 to be clamped into the first clamping hole 24. The pull rope 14 is made of elastic material. When the first clamping rod 21 is not aligned with the first clamping hole 24, the pull rope 14 can be further stretched. At the same time, the upward movement of the fixed plate 13 drives the movable supporting block 6 to move upward, so that the humidifier to be tested placed on the test bench 1 is supported, preparing for the subsequent driving of the humidifier to move.

[0044] Further, the connecting body includes a moving plate 8 and a slide rail 9 fixed to the inner bottom surface of the test bench 1 for the moving plate 8 to slide horizontally. A T-shaped rod 31 is penetrated on the surface of the moving plate 8. One end of the T-shaped rod 31 is connected to the moving plate 8 through a third spring 30. A connecting plate 28 is fixedly provided at the other end of the T-shaped rod 31. A slider 40 is vertically slidably provided on the inner surface of the connecting plate 28. The slider 40 is connected to the connecting plate 28 through a fourth spring 39. The pull rope 14 is fixedly connected to the slider 40. A clamping plate 7 is slidably provided on the upper end of the moving support block 6. A plug-in plate 32 is fixedly provided on the lower end of the clamping plate 7. The connecting plate The upper end of 28 is provided with a plug-in slot 29 that matches the plug-in plate 32, and the surface of the movable support block 6 is provided with a sliding cavity 33 for the plug-in plate 32 to slide. When the winding sleeve 17 rotates to reel in the two pull ropes 14, the reeling of the pull rope 14 first drives the connecting plate 28 to move, and the movement of the connecting plate 28 drives the clamping plate 7 to move through the plug-in plate 32, so that the two clamping plates 7 are close to each other, and the humidifier to be tested is clamped. After clamping, the pull rope 14 cannot drive the clamping plate 7 to continue to move. At this time, the pull rope 14 continues to be reeled and will be gradually straightened, thereby driving the slider 40 upward The movement effectively avoids excessive clamping of the humidifier and causing damage to the humidifier. Then, during the process of tightening and straightening the pull rope 14, the fixing plate 13 moves upward. The upward movement of the fixing plate 13 drives the movable supporting block 6 to move upward to support the humidifier to be detected. On the other hand, the first clamping rod 21 is engaged with the first clamping hole 24. On the other hand, the limiting groove 37 of the fixing plate 13 is disengaged from the wedge-shaped limiting block 16, preparing for the subsequent movement of the moving seat 12. Then the staff connects the charging line 3 to the charging interface of the humidifier to be detected to detect whether the humidifier is It can be charged normally. After the detection is completed, the motor 14 drives the screw rod 10 to rotate, and the rotation of the screw rod 10 drives the movable seat 12 to move. When the second pressure block 27 is aligned with the through groove 35, the second spring 26 resets the second clamping rod 25 to disengage from the second clamping hole, and then the third spring 30 and the fourth spring 39 reset the winding sleeve 17 to rotate to release the pull rope 14, and then the two clamping plates 7 move in the opposite direction to release the clamping of the humidifier, and the two movable supporting blocks 6 move downward under the action of gravity, so that the humidifier is placed on the test bench 1.

[0045] Furthermore, a current sensor connected to the charging line 3 is provided inside the controller 2. During the detection process, if the charging interface of the humidifier is damaged, the current sensor detects that the current of the charging line 3 is not within the normal range, and feeds back to the controller 2. The controller 2 controls the motor 4 to rotate forward, driving the movable support block 6 to move to one side, that is, driving the defective product to move to one side. Conversely, if the charging interface of the humidifier is normal, the controller 2 controls the motor 4 to reverse, that is, driving the defective product to move to the other side. When in use, placement plates can also be set at both ends of the test bench 1, so that after each detection is completed, the movement of the movable support block 6 drives the movement of the humidifier that has been inspected. Under the pushing action of the humidifier, the humidifier can be pushed onto the placement plate, which is convenient for the subsequent centralized removal of the humidifiers that have been inspected.

[0046] Furthermore, a guide rod 34 is movably provided on one side of the movable supporting block 6, one end of the guide rod 34 is threadedly connected to the inner wall of the sliding cavity 33, and a guide hole matching the guide rod 34 is provided on the surface of the plug-in plate 32, which effectively ensures the stability of the movement of the plug-in plate 32 and facilitates the disassembly and replacement of the clamping plate 7.

[0047] Furthermore, guide rollers 19 are rotatably provided on the surface of the movable seat 12 and cooperate with the two pull ropes 14 to drive the slider 40 to slide upward, so that the height of the guide rollers 19 is higher than the height of the slider 40, that is, the subsequent pull ropes 14 can make the slider 40 move upward during the tightening and straightening process, and further tightening of the pull ropes 14 can drive the fixed plate 13 to move further upward.

[0048] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
