[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example: Reference Figure 1-4The humidifying device for cold chain of fruits and vegetables shown in the figure comprises a cold chain transport vehicle body 1, an external refrigeration unit 2, a water tank and a humidifier 22. It should be noted that, in the present embodiment, the installation method of the cold chain transport vehicle body 1, the external refrigeration unit 2, the water tank and the humidifier 2 can refer to the technical content adopted in the humidifying mechanism of a cold chain transport vehicle disclosed in the Chinese patent with announcement number CN220180521U in the prior art, which will not be repeated here. Two mounting plates 3 are installed on the top inner wall of the cold chain transport vehicle body 1, and the sides of the two mounting plates 3 close to each other are jointly installed with a reciprocating screw rod 4. The inner wall of the side of the cold chain transport vehicle body 1 is fixed with a placement groove for placing An output motor 5 is installed on the inner wall of the side of the groove, one end of the reciprocating screw 4 is installed on the output shaft of the output motor 5, a U-shaped block 6 is threadedly sleeved on the reciprocating screw 4, two sliding rods 7 are installed on the relative inner walls of the U-shaped block 6, sliders 8 are slidably installed on the two sliding rods 7, and moving tubes 9 are installed at the bottom of the two sliders 8. Two elastic tubes 21 are installed at the output end of the humidifier 22, and the other ends of the two elastic tubes 21 are respectively installed on the sides of the two moving tubes 9 and are connected with the moving tubes 9. A plurality of humidifying heads 10 are installed at the bottom of the two moving tubes 9, and a driven mechanism is provided on the U-shaped block 6 to enable the moving tube 9 to move horizontally and longitudinally at the same time.

[0023] With the above structure, when in use, first start the humidifier 22. The output of the humidifier 22 will pass through the elastic tube 21 and the movable tube 9 to enable multiple humidification heads 10 to humidify the air. Then start the output motor 5. The output of the output motor 5 will cause the reciprocating screw 4 to rotate. The rotation of the reciprocating screw 4 will cause the U-shaped block 6 to move. The movement of the U-shaped block 6 will cause the slide bar 7 to move. The movement of the slide bar 7 will cause the slider 8 to move. The movement of the slider 8 will cause the movable tube 9 to move, thereby causing the humidification head 10 to move laterally. When the U-shaped block 6 moves, the slider 8 will move longitudinally through the driven mechanism. The longitudinal movement of the slider 8 causes the two movable tubes 9 to move longitudinally in an staggered manner, thereby causing the two rows of humidification heads 10 to move laterally and longitudinally at the same time, thereby evenly humidifying the inside of the cold chain transport vehicle body 1 for easy use.

[0024] like Figure 3As shown, the driven mechanism includes moving rods 12 respectively installed on the sides of the two sliders 8, two avoidance holes are provided on the side of the U-shaped block 6, one end of the two moving rods 12 passes through the two avoidance holes and is installed with a moving plate 13, two fixed plates 14 are installed on the side of the U-shaped block 6, the tops of the two fixed plates 14 are provided with rotating holes, and rotating rods 15 are rotatably installed on the two rotating holes, the bottoms of the two rotating rods 15 are installed with cams 17, the tops of the two rotating rods 15 are installed with gears 16, and the sides of the two mounting plates 3 close to each other are jointly installed with racks 18, and the two gears 16 are meshed with the racks 18, and the sides of the two sliders 8 are provided with elastic units. The advantage of such an arrangement is that the movable tube 9 can be easily moved longitudinally through the arrangement of the moving rod 12, the moving plate 13, the fixed plate 14, the rotating rod 15, the gear 16 and the cam 17.

[0025] Specifically, the movement of the U-shaped block 6 will cause the fixed plate 14 to move, and the movement of the fixed plate 14 will cause the gear 16 to move. Since the gear 16 is meshed with the rack 18 at this time, the gear 16 will rotate when it moves, and the rotation of the gear 16 will cause the rotating rod 15 to rotate, and the rotation of the rotating rod 15 will cause the cam 17 to rotate, and the rotation of the cam 17 will squeeze the movable plate 13 to move it, and the movement of the movable plate 13 will cause the movable rod 12 to move, and the movement of the movable rod 12 will cause the slider 8 to move, and the movement of the slider 8 will cause the movable tube 9 to move, thereby causing the humidifier head 10 to move laterally and longitudinally at the same time, so that the humidification is more uniform and easy to use.

[0026] like Figure 4 As shown, the elastic unit includes a spring 11 installed on the side of the slider 8, and the other end of the spring 11 is installed on the inner wall of the side of the U-shaped block 6. The advantage of this arrangement is that, through the arrangement of the spring 11, when the cam 17 is not squeezed, the slider 8 is reset under the action of the spring 11, and the reset of the slider 8 will reset the moving tube 9, thereby causing the moving tube 9 to reciprocate.

[0027] like Figure 3 As shown, the two cams 17 are staggered. The advantage of such arrangement is that it avoids the two cams 17 from contacting each other and makes the moving trajectories of the two moving tubes 9 different, thereby avoiding the situation where local spraying cannot occur.

[0028] Specifically, when one of the cams 17 squeezes the movable plate 13, the other cam 17 does not squeeze the other movable plate 13. At the same time, the two movable tubes 9 are biased in opposite directions. The movement at this time will cause one of the cams 17 to not squeeze the movable plate 13, and the other cam 17 to squeeze the other movable plate 13, thereby making the two movable tubes 9 opposite again and being in the position that was not humidified last time, thereby avoiding the situation where local spraying cannot occur.

[0029] like Figure 2As shown, the sides of the two mounting plates 3 close to each other are jointly installed with a guide rod 23, and the side of the U-shaped block 6 is provided with a guide hole, and the guide rod 23 passes through the guide hole. The advantage of such an arrangement is that the setting of the guide rod 23 has a certain guiding effect, so that the U-shaped block 6 moves in the horizontal direction.

[0030] like Figure 2 As shown, two limiting rings 20 are installed on the top of the cold chain transport vehicle body 1, and two elastic tubes 21 pass through the two limiting rings 20 respectively. The advantage of this arrangement is that through the arrangement of the limiting rings 20, it is convenient to limit the elastic tubes 21, thereby reducing the occurrence of the situation where the moving tube 9 moves and drives the elastic tubes 21 to move and contact with the vegetables.

[0031] like Figure 1 As shown, a drain pipe 19 is installed on the side of the water tank, and a through hole compatible with the drain pipe 19 is fixedly provided on the side of the cold chain transport vehicle body 1. A valve is fixedly provided on the drain pipe 19. The advantage of this arrangement is that through the setting of the drain pipe 19, it is convenient to replace the water in the water tank, avoiding the deterioration of water quality due to long-term use and affecting the subsequent humidification effect.

[0032] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. 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.
